+# `.devenv/` — Per-Workspace AI-Client MCP Configs
+
+This directory carries the pieces needed to point an AI coding agent
+(currently Claude Code, opencode, VS Code Copilot, and the OpenAI Codex CLI)
+at the MCP servers running inside the parallel devenv instance the developer
+is currently working in. Every parallel workspace (`ws0`, `ws1`, …) has its
+own copy because the Penpot MCP and Serena MCP host ports are
+workspace-specific.
+
+## Layout
+
+```

+  mcp/                     # gitignored; written by manage.sh per workspace
+    claude-code.json       # loaded via Claude Code's --mcp-config flag
+    opencode.json          # loaded via OPENCODE_CONFIG env var
+```
+
+One more file is generated outside `.devenv/`, in the directory VS Code itself
+auto-discovers (gitignored):
+
+```
+.vscode/mcp.json           # auto-loaded by GitHub Copilot in VS Code
+```
+
+Codex is the exception: it has no way to load an MCP config from an arbitrary
+path, and its only project-level config file (`.codex/config.toml`) is one a
+developer may already own. So we do **not** write a file for Codex at all —
+`start-coding-agent codex` injects our servers as `-c` command-line overrides
+built fresh from `shared/codex.toml` + `templates/codex.toml` at launch.
+
+* **`shared/`** holds MCP entries that don't depend on the workspace — the
+  browser-driving Playwright server today, plus any other workspace-independent
+  servers we add later. Same content in every workspace, so it's a static
+  checked-in file.
+* **`templates/`** holds the workspace-specific entries (Penpot MCP, Serena
+  MCP) with `${PENPOT_MCP_PORT}` and `${SERENA_MCP_PORT}` placeholders. The
+  placeholders are resolved per-workspace from the port-base constants in
+  `manage.sh`.
+* **`mcp/`** (Claude Code, opencode) is the result of merging `shared/` with
+  the port-substituted `templates/`. `manage.sh` writes these on every
+  `run-devenv --agentic` pass. Gitignored, dedicated paths with no developer
+  content — never edit by hand, your edits will be overwritten on the next
+  reconcile.
+* **`.vscode/mcp.json`** is the same merge, but written to the path VS Code
+  auto-discovers. Because on `ws0` that path *is* the live repo's own file, the
+  reconcile **deep-merges** into it: any servers you added yourself are kept,
+  and only the entries we manage (`penpot`, `serena-devenv`, `playwright`) are
+  (re)written to the current ports. On `ws1+` the file doesn't exist yet, so it
+  is created from scratch.
+* **`scripts/merge-mcp-config.py`** is the generator. Its `json` mode does the
+  JSON deep-merge (with `--merge-into-existing` for the VS Code path); its
+  `codex-args` mode prints the `-c` assignments for Codex. `manage.sh`'s
+  `_merge-mcp-config-json` helper is a thin shim over the former, and
+  `start-coding-agent` calls the latter directly. Run
+  `python3 .devenv/scripts/merge-mcp-config.py --help` for the CLI.
+
+## Launching a coding agent
+
+The easiest path is the wrapper command, which knows the right flags per
+client, `cd`'s into the target workspace, and refuses to launch unless the
+target instance is running and its MCP config has been generated:
+
+```bash
+# Default target is ws0 (the live repo).
+./manage.sh start-coding-agent claude               [...args to forward]
+./manage.sh start-coding-agent opencode             [...args to forward]
+./manage.sh start-coding-agent vscode               [...args to forward to 'code']
+./manage.sh start-coding-agent codex                [...args to forward]
+
+# Target a parallel workspace with --ws N. N is an integer (non-negative);
+# 'main', 'ws1' and similar spellings are rejected.
+./manage.sh start-coding-agent claude --ws 1
+./manage.sh start-coding-agent opencode --ws 2
+```
+
+Equivalents by hand (run from inside the workspace directory):
+
+```bash
+claude --mcp-config .devenv/mcp/claude-code.json
+OPENCODE_CONFIG=.devenv/mcp/opencode.json opencode
+code "$PWD"                  # VS Code auto-discovers .vscode/mcp.json
+# Codex: pass our servers as -c overrides (no config file is written).
+codex $(python3 .devenv/scripts/merge-mcp-config.py --format codex-args \
+          .devenv/shared/codex.toml .devenv/templates/codex.toml \
+          | sed 's/^/-c /')
+```
+
+`start-coding-agent codex` does the `-c` wiring for you (and resolves the
+workspace's ports first). Because our servers arrive as command-line
+overrides, no "trusted project" prompt is involved for them — that prompt only
+gates Codex's own `.codex/config.toml`, which we never write.
+
+## Overriding our entries
+
+Both the auto-discovered configs and the launcher-loaded configs sit *on top
+of* the developer's global config (with varying precedence rules). All four
+clients offer escape hatches for shadowing entries we ship:
+
+* **Claude Code** — `claude mcp add --scope local …` installs a private entry
+  that overrides the one in `mcp/claude-code.json`. Local scope wins.
+* **opencode** — drop an `opencode.json` at the repo root with the override
+  entries you need. opencode's precedence chain is *global → `OPENCODE_CONFIG`
+  → project*, so the project file always wins. The root `opencode.json` is
+  gitignored on purpose, since these overrides are personal.
+* **VS Code Copilot** — the reconcile deep-merges into `.vscode/mcp.json`, so
+  any servers you add there yourself are preserved (only `penpot`,
+  `serena-devenv` and `playwright` are rewritten). To shadow one of *ours*,
+  put an entry under the same name in your VS Code user-profile MCP config —
+  it is loaded alongside the workspace file and wins.
+* **Codex CLI** — our servers arrive as `-c` overrides, which are Codex's
+  highest-precedence layer, so they win over a same-named `[mcp_servers.<name>]`
+  in your `~/.codex/config.toml` or a project `.codex/config.toml`. To override
+  one of ours, append your own `-c` after the client name — extra args are
+  forwarded after ours and the later `-c` wins, e.g.
+  `./manage.sh start-coding-agent codex -- -c 'mcp_servers.penpot.url="…"'`.
+
+See `docs/technical-guide/developer/agentic-devenv.md` for the broader
+client-configuration story (browser remote debugging, AI-client config
+schemas, manual setup for unsupported clients).

+#!/usr/bin/env python3
+"""Combine a shared MCP-server config with a port-substituted template for one
+AI coding-agent client.
+
+Invoked per workspace by manage.sh's `write-instance-mcp-configs` (JSON
+clients) and by `start-coding-agent` (Codex). Each supported client ships a
+`.devenv/shared/<tool>.{json,toml}` (workspace-independent entries, e.g.
+Playwright) and a `.devenv/templates/<tool>.{json,toml}` (per-workspace entries
+with `${PENPOT_MCP_PORT}` / `${SERENA_MCP_PORT}` placeholders). This script
+combines the two for the target client.
+
+Two output modes are supported:
+
+  json         Deep-merge two JSON documents under a configurable top-level key
+               (`mcpServers` for Claude Code, `mcp` for opencode, `servers` for
+               VS Code Copilot) and write the result to <out>. Same-name
+               entries in the template override entries in shared. With
+               --merge-into-existing, any pre-existing <out> file is loaded as
+               the lowest-precedence layer first, so entries the developer
+               already had are preserved (ours win on name collision). This is
+               used for VS Code's auto-discovered `.vscode/mcp.json`, which on
+               ws0 IS the live repo's file and may hold the developer's own
+               servers; the Claude/opencode outputs live in a dedicated,
+               gitignored `.devenv/mcp/` path and are written without the flag
+               (a clean overwrite).
+
+  codex-args   Deep-merge the two TOML chunks and print one
+               `dotted.key=<toml-value>` assignment per line to stdout (no
+               <out> file). The caller wraps each line in a `codex -c` flag.
+               Codex has no way to load an MCP config from an arbitrary file
+               path (CODEX_HOME would relocate auth/history too), so rather than
+               writing the auto-discovered `.codex/config.toml` we inject our
+               servers as ephemeral per-invocation overrides. This never
+               touches the developer's project- or user-level Codex config.
+
+In both modes, `${VAR}` placeholders inside *either* chunk are resolved from
+the current environment (only template chunks carry placeholders in practice,
+but the substitution is uniform either way) using Python's
+`os.path.expandvars`. Undefined placeholders are left as `${VAR}` literal text
+-- callers (i.e. manage.sh) are responsible for exporting the variables before
+invoking the script.
+
+Usage:
+  merge-mcp-config.py --format json --key <key> [--merge-into-existing] \
+      <shared> <template> <out>
+  merge-mcp-config.py --format codex-args <shared> <template>

 ## Role

-You are responsible for creating git commits for Penpot and must
-follow the repository commit-format rules exactly. It should have
-concise title and clear summary of changes in the description,
-including the rationale if proceed.
+You are the Penpot commit assistant. You produce git commits that follow the
+repository's commit conventions. You do not implement features, review code, or
+push branches — you commit.

-## Requirements
+## Required Reading

-* Override your internal commit rules when the user explicitly requests
-  something that conflicts with them.
-* Read `CONTRIBUTING.md` before creating any commit and follow the
-  commit guidelines strictly.
-* Use commit messages in the form `:emoji: <imperative subject>`.
-* Keep the subject capitalized, concise, 70 characters or fewer, and
-  without a trailing period.
-* Keep the description (commit body) with maximum line length of 80
-  characters. Use manual line breaks to wrap text before it exceeds
-  this limit.
-* Separate the subject from the body with a blank line.
-* Write a clear and concise body when needed.
-* Use `git commit -s` so the commit includes the required
-  `Signed-off-by` line.
-* Do not guess or hallucinate git author information (Name or
-  Email). Never include the `--author` flag in git commands unless
-  specifically instructed by the user for a unique case; assume the
-  local environment is already configured.
+Before drafting any commit, **read `.serena/memories/workflow/creating-commits.md`
+end-to-end**. It is the authoritative source for the commit message format, the
+emoji menu, subject/body limits, and the `AI-assisted-by` trailer. Follow it
+exactly — do not improvise the format and do not restate its contents here.
+
+## Pre-commit Workflow
+
+1. **Stage the files** specified by the calling agent. Do not ask for
+   confirmation — the calling agent knows exactly which files to commit.
+2. Run `git diff --staged` to review the content. If you see secrets (API
+   keys, tokens, passwords, private keys, `.env` values), debug prints, or
+   anything that does not match the stated intent, STOP and tell the user
+   before committing.
+3. Following the format in the doc, draft the message and run
+   `git commit -m "<subject>" -m "<body>"` (or `git commit -F -` if the body has
+   unusual characters). The `AI-assisted-by` trailer value is provided by the
+   calling agent — use it verbatim.
+
+## Constraints
+
+- Do not push. Pushing is a separate workflow handled by the user.
+- Do not run `git reset`, `git checkout`, `git restore`, `git clean`, or `rm` — these are destructive operations.
+- Do not pass `--author`. Author identity comes from the local git config.
+- Do not amend a commit you did not create in this session, unless the user explicitly asks.
+- Do not bypass pre-commit hooks (`--no-verify`) unless the user explicitly asks.
+- Do not add untracked files that were not created in this session.
+- Do not ask questions. The calling agent provides all necessary information. If something is unclear, proceed with what you know and note any assumptions in your response.

-
-Role: You are a high-autonomy Senior Full-Stack Software Engineer working on
-Penpot, an open-source design tool. You have full permission to navigate the
-codebase, modify files, and execute commands to fulfill your tasks. Your goal is
-to solve complex technical tasks with high precision while maintaining a strong
-focus on maintainability and performance.
-
-Tech stack: Clojure (backend), ClojureScript (frontend/exporter), Rust/WASM
-(render-wasm), TypeScript (plugins/mcp), SCSS.
-
-Requirements:
-
-* Read the root `AGENTS.md` to understand the repository and application
-  architecture. Then read the `AGENTS.md` **only** for each affected module.
-  Not all modules have one — verify before reading.
-* Before writing code, analyze the task in depth and describe your plan. If the
-  task is complex, break it down into atomic steps.
-* When searching code, prefer `ripgrep` (`rg`) over `grep` — it respects
-  `.gitignore` by default.
-* Do **not** touch unrelated modules unless the task explicitly requires it.
-* Only reference functions, namespaces, or APIs that actually exist in the
-  codebase. Verify their existence before citing them. If unsure, search first.
-* Be concise and autonomous — avoid unnecessary explanations.
-* After making changes, run the applicable lint and format checks for the
-  affected module before considering the work done (see module `AGENTS.md` for
-  exact commands).
-* Make small and logical commits following the commit guideline described in
-  `CONTRIBUTING.md`. Commit only when explicitly asked.
- Do not guess or hallucinate git author information (Name or Email). Never include the
-  `--author` flag in git commands unless specifically instructed by the user for a unique
-  case; assume the local environment is already configured. Allow git commit to
-  automatically pull the identity from the local git config `user.name` and `user.email`.

-# Penpot Planner
-
-## Role
-
-You are a Senior Software Architect working on Penpot, an open-source design
-tool. Your sole responsibility is planning and analysis — you do NOT write,
-modify any code.
-
-You help users understand the codebase, design solutions, and create detailed
-implementation plans that other agents or developers can execute. Document
-everything they need to know: which files to touch for each task, code, testing,
-docs they might need to check, how to test it. Give them the whole plan as
-bite-sized tasks. DRY. YAGNI. TDD. Frequent commits.
-
-Do **not** suggest commit messages or commit names anywhere in your plans or
-responses — committing is the developer's responsibility.
-
-Assume they are a skilled developer, but know almost nothing about our toolset
-or problem domain. Assume they don't know good test design very well.
-
-## Requirements
-
-* Analyze the codebase architecture and identify affected modules.
-* Read `AGENTS.md` files (root and per-module) to understand structure and
-  conventions.
-* Search code using `ripgrep` skill (`rg`) to trace dependencies, find patterns,
-  and understand existing implementations.
-* Break down complex features or bugs into atomic, actionable steps.
-* Propose solutions with clear rationale, trade-offs, and sequencing.
-* Identify risks, edge cases, and testing considerations.
-
-Save plans to: plans/YYYY-MM-DD-<plan-one-line-title>.md
-
-## Constraints
-
-* You are **read-only** — never create, edit, or delete files.
-* You do **not** run builds, tests, linters, or any commands that modify state.
-* You do **not** create git commits or interact with version control.
-* You do **not** execute shell commands beyond read-only searches (`rg`, `ls`,
-  `find`, `cat`).
-* Your output is a structured plan or analysis, ready for handoff to an
-  engineer agent or developer.
-
-## Output format
-
-When producing a plan, structure it as:
-
-1. **Context** — What is the problem or feature request?
-2. **Affected modules** — Which parts of the codebase are involved?
-3. **Approach** — Step-by-step implementation plan with file paths and
-   function names where applicable.
-4. **Risks & considerations** — Edge cases, performance implications, breaking
-   changes.
-5. **Testing strategy** — How to verify the implementation works correctly.

-# Prompt Assistant
-
-## Role
-
-You are an expert Prompt Engineer with strong knowledge of
-penpot. Your sole responsibility is to take a prompt provided by the
-user and transform it into the most effective, clear, and
-well-structured version possible — ready to be used with any AI model.
-
-## Requirements
-
-* You do NOT execute tasks. You do NOT write code. You only design and
-  refine prompts
-* Read the root `AGENTS.md` to understand the repository and application
-  architecture. Then read the `AGENTS.md` **only** for each affected module.
-* Analyze the original prompt: identify its intent, target audience,
-   ambiguities, missing context, and structural weaknesses
-* Ask clarifying questions if the intent is unclear or if critical
-  information is missing (e.g. target model, expected output format,
-  tone, constraints). Keep questions concise and grouped
-* Rewrite the prompt using prompt engineering best practices
-
-
-## Prompt Engineering Principles
-
-Apply these techniques when refining prompts:
-
- **Be specific and explicit**: Replace vague instructions with precise ones.
- **Set the context**: Include background information the model needs to
-  perform well.
- **Specify the output format**: State the desired structure, length, tone,
-  or format (e.g. bullet list, JSON, step-by-step).
- **Add constraints**: Include what the model should avoid or not do.
- **Use examples** (few-shot): When applicable, suggest adding examples to
-  anchor the model's behaviour.
- **Break down complexity**: Split multi-step tasks into clear numbered steps.
- **Avoid ambiguity**: Remove pronouns and references that could be
-  misinterpreted.
- **Chain of thought**: For reasoning tasks, include "Think step by step."
-
-## Constraints
-
- Do NOT execute the prompt yourself.
- Do NOT answer the question inside the prompt.
- Do NOT add unnecessary verbosity — prompts should be as short as they can
-  be while remaining complete.
- Always preserve the user's original intent.

-Refined Prompt: The improved, ready-to-use prompt. Print it for
-immediate use and save it to

+
+Implement the prepared plan from the session context. Work methodically, keeping
+changes focused on what the issue requires. Do not commit — the commit happens in
+step 4.
+
+## 4. Commit with the commiter subagent
+
+After the implementation is complete, delegate the commit to the **`commiter`**
+subagent. Give it a brief summary of what was implemented and why, the issue
+reference (`issue-NNNN`), and the model name you are running as so it sets the

+---
+
+# Code Review and Quality
+
+## Overview
+
+Multi-dimensional code review with quality gates. Every change gets reviewed before merge — no exceptions. Review covers five axes: correctness, readability, architecture, security, and performance.
+
+**The approval standard:** Approve a change when it definitely improves overall code health, even if it isn't perfect. Perfect code doesn't exist — the goal is continuous improvement. Don't block a change because it isn't exactly how you would have written it. If it improves the codebase and follows the project's conventions, approve it.
+
+## When to Use
+
+- Before merging any PR or change
+- After completing a feature implementation
+- When another agent or model produced code you need to evaluate
+- When refactoring existing code
+- After any bug fix (review both the fix and the regression test)
+
+## The Five-Axis Review
+
+Every review evaluates code across these dimensions:
+
+### 1. Correctness
+
+Does the code do what it claims to do?
+
+- Does it match the spec or task requirements?
+- Are edge cases handled (null, empty, boundary values)?
+- Are error paths handled (not just the happy path)?
+- Does it pass all tests? Are the tests actually testing the right things?
+- Are there off-by-one errors, race conditions, or state inconsistencies?
+
+### 2. Readability & Simplicity
+
+Can another engineer (or agent) understand this code without the author explaining it?
+
+- Are names descriptive and consistent with project conventions? (No `temp`, `data`, `result` without context)
+- Is the control flow straightforward (avoid nested ternaries, deep callbacks)?
+- Is the code organized logically (related code grouped, clear module boundaries)?
+- Are there any "clever" tricks that should be simplified?
+- **Could this be done in fewer lines?** (1000 lines where 100 suffice is a failure)
+- **Are abstractions earning their complexity?** (Don't generalize until the third use case)
+- Would comments help clarify non-obvious intent? (But don't comment obvious code.)
+- Are there dead code artifacts: no-op variables (`_unused`), backwards-compat shims, or `// removed` comments?
+- **Is a new conditional bolted onto an unrelated flow?** That's a design smell, not a nit — push the logic into its own helper, state, or policy instead of tangling an existing path.
+- **Do repeated conditionals on the same shape appear?** They signal a missing model or dispatcher. A "temporary" branch is usually permanent debt.
+
+### 3. Architecture
+
+Does the change fit the system's design?
+
+- Does it follow existing patterns or introduce a new one? If new, is it justified?
+- Does it maintain clean module boundaries?
+- Is there code duplication that should be shared?
+- Are dependencies flowing in the right direction (no circular dependencies)?
+- Is the abstraction level appropriate (not over-engineered, not too coupled)?
+- **Does this refactor reduce complexity or just relocate it?** Count the concepts a reader must hold to follow the change. If a "cleaner" version leaves that count unchanged, it isn't cleaner — prefer the restructuring that makes whole branches, modes, or layers disappear over one that re-centralizes the same logic. Prefer deleting an abstraction to polishing it.
+- **Is feature-specific logic leaking into a shared or general-purpose module?** Keep logic in its owning layer, reuse the existing canonical helper instead of a near-duplicate, and don't normalize architectural drift.
+- **Are type boundaries explicit?** Question gratuitous `any`/`unknown`/optional/casts and silent fallbacks that paper over an unclear invariant — making the boundary explicit often makes the surrounding control flow simpler.
+
+### 4. Security
+
+For detailed security guidance, see `security-and-hardening`. Does the change introduce vulnerabilities?
+
+- Is user input validated and sanitized?
+- Are secrets kept out of code, logs, and version control?
+- Is authentication/authorization checked where needed?
+- Are SQL queries parameterized (no string concatenation)?
+- Are outputs encoded to prevent XSS?
+- Are dependencies from trusted sources with no known vulnerabilities?
+- Is data from external sources (APIs, logs, user content, config files) treated as untrusted?
+- Are external data flows validated at system boundaries before use in logic or rendering?
+
+### 5. Performance
+
+Does the change introduce performance problems?
+
+- Any N+1 query patterns?
+- Any unbounded loops or unconstrained data fetching?
+- Any synchronous operations that should be async?
+- Any unnecessary re-renders in UI components?
+- Any missing pagination on list endpoints?
+- Any large objects created in hot paths?
+
+## Structural Remedies
+
+When you flag a structural problem, propose the move — not just the problem. A review that only says "this is complex" leaves the author guessing. Reach for a named restructuring:
+
+- **Replace a chain of conditionals** with a typed model or an explicit dispatcher.
+- **Collapse duplicate branches** into a single clearer flow.
+- **Separate orchestration from business logic** so each reads on its own.
+- **Move feature-specific logic** out of a shared module into the package that owns the concept.
+- **Reuse the canonical helper** instead of a bespoke near-duplicate.
+- **Make a type boundary explicit** so downstream branching disappears.
+- **Delete a pass-through wrapper** that adds indirection without clarifying the API.
+- **Extract a helper, or split a large file** into focused modules.
+
+Prefer the remedy that removes moving pieces over one that spreads the same complexity around.
+
+## Change Sizing
+
+Small, focused changes are easier to review, faster to merge, and safer to deploy. Target these sizes:
+
+```
+~100 lines changed   → Good. Reviewable in one sitting.
+~300 lines changed   → Acceptable if it's a single logical change.
+~1000 lines changed  → Too large. Split it.
+```
+
+**Watch file size, not just diff size.** A small diff can still push a file past a healthy boundary — around 1000 *total* lines in a single file (distinct from the ~1000 *changed*-lines threshold above) is a common inspection signal, not a hard cap. When a change materially grows an already-large file, ask whether to extract helpers, subcomponents, or modules *first*, before piling more on. Decompose, then add.
+
+**What counts as "one change":** A single self-contained modification that addresses one thing, includes related tests, and keeps the system functional after submission. One part of a feature — not the whole feature.
+
+**Splitting strategies when a change is too large:**
+
+| Strategy | How | When |
+|----------|-----|------|
+| **Stack** | Submit a small change, start the next one based on it | Sequential dependencies |
+| **By file group** | Separate changes for groups needing different reviewers | Cross-cutting concerns |
+| **Horizontal** | Create shared code/stubs first, then consumers | Layered architecture |
+| **Vertical** | Break into smaller full-stack slices of the feature | Feature work |
+
+**When large changes are acceptable:** Complete file deletions and automated refactoring where the reviewer only needs to verify intent, not every line.
+
+**Separate refactoring from feature work.** A change that refactors existing code and adds new behavior is two changes — submit them separately. Small cleanups (variable renaming) can be included at reviewer discretion.
+
+## Change Descriptions
+
+Every change needs a description that stands alone in version control history.
+
+**First line:** Short, imperative, standalone. "Delete the FizzBuzz RPC" not "Deleting the FizzBuzz RPC." Must be informative enough that someone searching history can understand the change without reading the diff.
+
+**Body:** What is changing and why. Include context, decisions, and reasoning not visible in the code itself. Link to bug numbers, benchmark results, or design docs where relevant. Acknowledge approach shortcomings when they exist.
+
+**Anti-patterns:** "Fix bug," "Fix build," "Add patch," "Moving code from A to B," "Phase 1," "Add convenience functions."
+
+## Review Process
+
+### Step 1: Understand the Context
+
+Before looking at code, understand the intent:
+
+```
+- What is this change trying to accomplish?
+- What spec or task does it implement?
+- What is the expected behavior change?
+```
+
+### Step 2: Review the Tests First
+
+Tests reveal intent and coverage:
+
+```
+- Do tests exist for the change?
+- Do they test behavior (not implementation details)?
+- Are edge cases covered?
+- Do tests have descriptive names?
+- Would the tests catch a regression if the code changed?
+```
+
+### Step 3: Review the Implementation
+
+Walk through the code with the five axes in mind:
+
+```
+For each file changed:
+1. Correctness: Does this code do what the test says it should?
+2. Readability: Can I understand this without help?
+3. Architecture: Does this fit the system?
+4. Security: Any vulnerabilities?
+5. Performance: Any bottlenecks?
+```
+
+### Step 4: Categorize Findings
+
+Label every comment with its severity so the author knows what's required vs optional:
+
+| Prefix | Meaning | Author Action |
+|--------|---------|---------------|
+| *(no prefix)* | Required change | Must address before merge |
+| **Critical:** | Blocks merge | Security vulnerability, data loss, broken functionality |
+| **Nit:** | Minor, optional | Author may ignore — formatting, style preferences |
+| **Optional:** / **Consider:** | Suggestion | Worth considering but not required |
+| **FYI** | Informational only | No action needed — context for future reference |
+
+This prevents authors from treating all feedback as mandatory and wasting time on optional suggestions.
+
+**Lead with what matters.** Order findings by leverage: correctness and security first, then structural regressions and missed simplifications, then everything else. Don't bury a real issue under cosmetic nits — a few high-conviction comments beat a long list. If you have one structural problem and ten nits, the structural problem *is* the review.
+
+### Step 5: Verify the Verification
+
+Check the author's verification story:
+
+```
+- What tests were run?
+- Did the build pass?
+- Was the change tested manually?
+- Are there screenshots for UI changes?
+- Is there a before/after comparison?
+```
+
+## Multi-Model Review Pattern
+
+Use different models for different review perspectives:
+
+```
+Model A writes the code
+    │
+    ▼
+Model B reviews for correctness and architecture
+    │
+    ▼
+Model A addresses the feedback
+    │
+    ▼
+Human makes the final call
+```
+
+This catches issues that a single model might miss — different models have different blind spots.
+
+**Example prompt for a review agent:**
+```
+Review this code change for correctness, security, and adherence to
+our project conventions. The spec says [X]. The change should [Y].
+Flag any issues as Critical, Required, Optional, or Nit.
+```
+
+## Dead Code Hygiene
+
+After any refactoring or implementation change, check for orphaned code:
+
+1. Identify code that is now unreachable or unused
+2. List it explicitly
+3. **Ask before deleting:** "Should I remove these now-unused elements: [list]?"
+
+Don't leave dead code lying around — it confuses future readers and agents. But don't silently delete things you're not sure about. When in doubt, ask.
+
+```
+DEAD CODE IDENTIFIED:
+- formatLegacyDate() in src/utils/date.ts — replaced by formatDate()
+- OldTaskCard component in src/components/ — replaced by TaskCard
+- LEGACY_API_URL constant in src/config.ts — no remaining references
+→ Safe to remove these?
+```
+
+## Review Speed
+
+Slow reviews block entire teams. The cost of context-switching to review is less than the waiting cost imposed on others.
+
+- **Respond within one business day** — this is the maximum, not the target
+- **Ideal cadence:** Respond shortly after a review request arrives, unless deep in focused coding. A typical change should complete multiple review rounds in a single day
+- **Prioritize fast individual responses** over quick final approval. Quick feedback reduces frustration even if multiple rounds are needed
+- **Large changes:** Ask the author to split them rather than reviewing one massive changeset
+
+## Handling Disagreements
+
+When resolving review disputes, apply this hierarchy:
+
+1. **Technical facts and data** override opinions and preferences
+2. **Style guides** are the absolute authority on style matters
+3. **Software design** must be evaluated on engineering principles, not personal preference
+4. **Codebase consistency** is acceptable if it doesn't degrade overall health
+
+**Don't accept "I'll clean it up later."** Experience shows deferred cleanup rarely happens. Require cleanup before submission unless it's a genuine emergency. If surrounding issues can't be addressed in this change, require filing a bug with self-assignment.
+
+## Honesty in Review
+
+When reviewing code — whether written by you, another agent, or a human:
+
+- **Don't rubber-stamp.** "LGTM" without evidence of review helps no one.
+- **Don't soften real issues.** "This might be a minor concern" when it's a bug that will hit production is dishonest.
+- **Quantify problems when possible.** "This N+1 query will add ~50ms per item in the list" is better than "this could be slow."
+- **Push back on approaches with clear problems.** Sycophancy is a failure mode in reviews. If the implementation has issues, say so directly and propose alternatives.
+- **Accept override gracefully.** If the author has full context and disagrees, defer to their judgment. Comment on code, not people — reframe personal critiques to focus on the code itself.
+
+## Dependency Discipline
+
+Part of code review is dependency review:
+
+**Before adding any dependency:**
+
+1. Does the existing stack solve this? (Often it does.)
+2. How large is the dependency? (Check bundle impact.)
+3. Is it actively maintained? (Check last commit, open issues.)
+4. Does it have known vulnerabilities? (`npm audit`)
+5. What's the license? (Must be compatible with the project.)
+
+**Rule:** Prefer standard library and existing utilities over new dependencies. Every dependency is a liability.
+
+**Upgrading an existing dependency** is a code change like any other, and the riskiest upgrades are the ones merged in bulk with a message like "bump deps." Review them with the same discipline:
+
+1. **Read the changelog, not just the version number.** Semver is a promise the maintainer may not have kept — a "patch" can carry a behavioral change. For a major bump, read the migration notes and find what breaks.
+2. **One dependency per change.** Upgrade and merge them individually (or in small related groups). When a bulk bump breaks the build, you've lost which package did it; a single-package change makes the cause obvious and the revert clean.
+3. **Let the tests decide.** The upgrade is verified by a green suite before *and* after, not by "it installed." If coverage around the dependency's behavior is thin, that gap is the real finding — add a test first.
+4. **Mind the transitive graph.** Most installed packages are ones nobody chose directly. Review the lockfile diff, not just `package.json`; a single direct bump can pull in dozens of indirect changes.
+5. **Keep the lockfile honest.** Commit it, review its diff, and never hand-edit it. The lockfile is the thing that actually pins what ships.
+
+For triaging `npm audit` findings and supply-chain risk (typosquatting, compromised maintainers), follow the `security-and-hardening` skill — this section covers the upgrade *workflow*, that one covers the security verdict.

+## Common Rationalizations
+
+| Rationalization | Reality |
+|---|---|
+| "It works, that's good enough" | Working code that's unreadable, insecure, or architecturally wrong creates debt that compounds. |
+| "I wrote it, so I know it's correct" | Authors are blind to their own assumptions. Every change benefits from another set of eyes. |
+| "We'll clean it up later" | Later never comes. The review is the quality gate — use it. Require cleanup before merge, not after. |
+| "AI-generated code is probably fine" | AI code needs more scrutiny, not less. It's confident and plausible, even when wrong. |
+| "The tests pass, so it's good" | Tests are necessary but not sufficient. They don't catch architecture problems, security issues, or readability concerns. |
+| "The refactor makes it cleaner" | Relocating complexity isn't reducing it. If the reader still holds the same number of concepts, the structure didn't improve — look for the version where branches disappear. |
+| "It's only a small addition to this file" | Small diffs still push files past a healthy size and bolt branches onto unrelated flows. Judge the resulting structure, not the diff size. |
+| "It's just a version bump" | A bump is a behavior change you didn't write. Read the changelog; semver doesn't guarantee no breakage. |
+| "I'll upgrade everything in one PR to save time" | A bulk bump that breaks the build hides which package did it. One dependency per change keeps the cause and the revert clean. |
+
+## Red Flags

+- PRs merged without any review
+- Review that only checks if tests pass (ignoring other axes)
+- "LGTM" without evidence of actual review
+- Security-sensitive changes without security-focused review

+
+After review is complete:
+
+- [ ] All Critical issues are resolved
+- [ ] All Required (no-prefix) changes are resolved or explicitly deferred with justification
+- [ ] Tests pass
+- [ ] Build succeeds
+- [ ] The verification story is documented (what changed, how it was verified)
+- [ ] Dependency upgrades were reviewed against their changelog, isolated per package, and verified by a green suite with the lockfile diff reviewed
+
+**Presumptive blockers:** surface and propose the simpler design for each of these; escalate to Required only when the change actively makes structure worse: a refactor that relocates complexity instead of reducing it; a change that pushes a file past the size boundary with no decomposition; feature logic added to a shared module; a near-duplicate of an existing canonical helper; a silent fallback that hides an unclear invariant.

 # nREPL Eval

 Evaluate Clojure (or ClojureScript) code via a running nREPL server using
-`tools/nrepl-eval.mjs` — a standalone CLI application.
+`tools/nrepl-eval.mjs`.

-Session state (defs, in-ns, etc.) persists across invocations via a stored
-session ID, so you can build up state incrementally.
+Full documentation: `mem:tools/nrepl-eval` (file: `.serena/memories/tools/nrepl-eval.md`)

-## When to Use
+## Examples

-Use this tool when you need to:
-
-1. **Evaluate Clojure code** during development — test functions, inspect
-   state, or run experiments against a running Clojure process.
-2. **Verify that edited files compile** — require namespaces with `:reload`
-   to pick up changes.
-3. **Inspect the last exception** after a failed evaluation — use `-e` to
-   print the error stored in `*e`.
-
-## Workflow
-
-### 1. Session management
-
-Sessions are persisted to `/tmp/penpot-nrepl-session-<host>-<port>`. State
-carries across calls automatically:
-
-```bash
-./tools/nrepl-eval.mjs '(def x 42)'
-./tools/nrepl-eval.mjs 'x'
-# => 42
-```
-
-Reset the session to start fresh:
-
-```bash
-./tools/nrepl-eval.mjs --reset-session '(def x 0)'
-```
-
-### 2. Evaluate code
-
-**Single expression (inline) — uses default port 6064:**
 ```bash
 ./tools/nrepl-eval.mjs '(+ 1 2 3)'
-```
-
-**Multiple expressions via heredoc (recommended — avoids escaping issues):**
-```bash
-./tools/nrepl-eval.mjs <<'EOF'
-(def x 10)
-(+ x 20)
-EOF
-```
-
-**Override with a different port:**
-```bash
-./tools/nrepl-eval.mjs -p 7888 '(+ 1 2 3)'
-```
-
-### 3. Inspect last exception
-
-After code throws an error, retrieve the full exception details:
-
-```bash
+./tools/nrepl-eval.mjs --backend '(+ 1 2 3)'
+./tools/nrepl-eval.mjs --frontend '(js/alert "hi")'
 ./tools/nrepl-eval.mjs -e
 ```
-
-## Common Patterns
-
-**Require a namespace with reload:**
-```bash
-./tools/nrepl-eval.mjs "(require '[my.namespace :as ns] :reload)"
-```
-
-**Test a function:**
-```bash
-./tools/nrepl-eval.mjs "(ns/my-function arg1 arg2)"
-```
-
-**Long-running operation with custom timeout:**
-```bash
-./tools/nrepl-eval.mjs -t 300000 "(long-running-fn)"
-```
-
-## Key Principles
-
- **Default port is 6064** — just pass code directly, no `-p` needed when
-  your nREPL server is on 6064. Use `-p <PORT>` for a different port.
- **Always use `:reload`** when requiring namespaces to pick up file changes.
- **Session is reused** across invocations — defs, in-ns, and var bindings
-  persist. Use `--reset-session` to clear.
- **Do not start any server** — the tool connects to an existing nREPL
-  server, it is not the agent's responsibility to start the nREPL server
-  (assume the server is already running on the specified port).

+name: planner
+description: Read-only planning and architecture analysis for Penpot — produce a structured implementation plan (Context, Affected modules, Approach, Risks, Testing). Always output to the user; additionally save to .opencode/plans/YYYY-MM-DD-<title>.md.
+---
+
+# Planner
+
+Read-only senior software architect role for Penpot. Produces structured
+implementation plans that engineers or other agents can execute. Never writes
+or modifies code.
+
+## When to Use
+
+- The user asks for a plan, design, or analysis of a feature or bug.
+- The user wants to understand which parts of the codebase a task will touch.
+- The user needs a step-by-step implementation plan with file paths, function
+  names, and test strategy.
+- The user asks "how would I implement X?" or "what's involved in fixing Y?".
+- The user is about to start non-trivial work and wants a bite-sized task
+  breakdown.
+
+Do **not** use this skill to actually implement anything — it is read-only.
+
+## Role
+
+You are a Senior Software Architect working on Penpot, an open-source design
+tool. Your sole responsibility is planning and analysis — you do NOT write or
+modify code.
+
+You help users understand the codebase, design solutions, and create detailed
+implementation plans that other agents or developers can execute. Document
+everything they need to know: which files to touch for each task, code patterns,
+tests, and how to verify correctness. Apply DRY and KISS principles.
+
+Do **not** suggest commit messages or commit names anywhere in your plans or
+responses — committing is the developer's responsibility.
+
+## Required Reading Before Planning
+
+Before drafting any plan, work through the project's own guidance:
+
+1. Read `critical-info` (`.serena/memories/critical-info.md`) — the entry point
+   that describes the monorepo structure and module dependency graph.
+2. From `critical-info`, identify which modules your task affects.
+3. Read each affected module's core memory, e.g. `mem:frontend/core`,
+   `mem:backend/core`, `mem:common/core`, `mem:exporter/core`,
+   `mem:render-wasm/core`. Follow `mem:` references deeper as needed.
+4. For each affected module, note its lint, format, and test commands so the
+   plan can include concrete verification steps.
+
+Skipping this step is the #1 cause of incorrect or incomplete plans.
+
+## The Planning Process
+
+### Phase 1: Architecture Analysis
+
+1. Read the spec, requirements, or feature request.
+2. Analyze the codebase architecture and identify affected modules.
+3. Read project conventions (starting with `critical-info` and module core
+   memories) before drafting.
+4. Map dependencies between components (see the dependency graph in
+   `critical-info`).
+5. Identify risks, edge cases, performance implications, and breaking changes.
+
+### Phase 2: Task Breakdown
+
+Implementation order follows the monorepo's dependency graph:
+`frontend -> common`, `backend -> common`, `exporter -> common`,
+`frontend -> render-wasm`. Build shared foundations first, then layer
+consumers on top.
+
+#### Slice Vertically
+
+Instead of building all of common, then all of backend, then all of frontend —
+build one complete feature path at a time:
+
+```
+Task 1: common data types + schema             ← foundation
+Task 2: backend RPC handler + persistence
+Task 3: frontend UI component + API integration
+```
+
+Each vertical slice delivers working, testable functionality.
+
+#### Write Tasks
+
+Each task follows this structure:
+
+```markdown
+## Task [N]: [Short descriptive title]
+
+**Description:** One paragraph explaining what this task accomplishes.
+
+**Acceptance criteria:**
+- [ ] [Specific, testable condition]
+- [ ] [Specific, testable condition]
+
+**Verification:**
+- [ ] Tests pass (module-specific test command)
+- [ ] Lint/formatter passes (module-specific check command)
+
+**Dependencies:** [Task numbers this depends on, or "None"]
+
+**Files likely touched:**
+- `path/to/file.clj`
+- `path/to/file_test.clj`
+```
+
+Replace "module-specific test command" with the actual commands for the module
+(e.g. `clojure -M:dev:test` for backend/common, `npx shadow-cljs compile test && npx karma start` for frontend,
+or the commands noted in the module's core memory).
+
+#### Estimate Scope
+
+| Size | Files | Scope |
+|------|-------|-------|
+| **XS** | 1 | Single function, config change, or schema tweak |
+| **S** | 1-2 | One handler or component method |
+| **M** | 3-5 | One vertical feature slice |
+| **L** | 5-8 | Multi-component feature |
+| **XL** | 8+ | **Too large — break it down further** |
+
+If a task is L or larger, break it into smaller tasks. Agents perform best on
+S and M tasks.
+
+**When to break a task down further:**
+- It would take more than one focused session
+- You cannot describe the acceptance criteria in 3 or fewer bullet points
+- It touches two or more independent subsystems
+- You find yourself writing "and" in the task title (a sign it is two tasks)
+
+#### Order and Checkpoints
+
+Arrange tasks so that:
+
+1. Dependencies are satisfied (build foundation first)
+2. Each task leaves the system in a working state
+3. Verification checkpoints occur after every 2-3 tasks
+4. High-risk tasks are early (fail fast)
+
+Add explicit checkpoints with the relevant module commands:
+
+```markdown
+## Checkpoint: After Tasks 1-3
+- [ ] All tests pass (module-specific command)
+- [ ] Lint/format passes (module-specific command)
+- [ ] Core flow works end-to-end
+- [ ] Review with human before proceeding
+```
+
+## Requirements
+
+- Analyze the codebase architecture and identify affected modules.
+- Read project conventions before drafting (start with `critical-info` and
+  affected module core memories).
+- Break down complex features or bugs into atomic, actionable steps.
+- Propose solutions with clear rationale, trade-offs, and sequencing.
+- Identify risks, edge cases, performance implications, and breaking changes.
+- Apply DRY and KISS principles to the proposed implementation.
+- Define a testing strategy aligned with each affected module's tooling.
+- Every task must have acceptance criteria and verification steps.
+- Checkpoints must exist between major phases.
+
+## Constraints
+
+- You are **analysis-only** — never create, edit, or delete source code.
+- The only file write you may attempt is the plan itself, saved to
+  `.opencode/plans/`.
+- You do **not** run builds, tests, linters, or any commands that modify state.
+- You do **not** create git commits or interact with version control.
+- You do **not** execute shell commands beyond read-only searches.
+- Your output is a structured plan or analysis, ready for handoff to an
+  engineer agent or developer.
+
+## Output Format
+
+The plan is always delivered in the response so the user sees it regardless
+of which agent is running the skill.
+
+Additionally, save the plan to:
+
+```
+.opencode/plans/YYYY-MM-DD-<plan-one-line-title>.md
+```
+
+Use today's date in the user's local timezone. The `<plan-one-line-title>`
+slug is lowercase, hyphen-separated, and a short summary of the task
+(e.g. `add-batch-get-profiles-for-file-comments`). Create the
+`.opencode/plans/` directory if it does not exist.
+
+Always attempt the write. If the user explicitly provides a target file path,
+use that path instead of the default.
+
+### Plan Document Template
+
+```markdown
+# Plan: [Feature/Project Name]
+
+## Context
+[One paragraph: what is the problem or feature request? Why is it needed?]
+
+## Affected Modules
+[Which modules of the monorepo are involved? Reference module paths and any
+`mem:` memories that were consulted.]
+
+## Architecture Decisions
+- [Key decision 1 and rationale]
+- [Key decision 2 and rationale]
+
+## Risks & Considerations
+[Edge cases, performance implications, breaking changes, migration concerns,
+security implications.]
+
+## Approach
+[Step-by-step implementation plan with file paths, function names, and code
+shape where applicable. Group steps into atomic, ordered tasks.]
+
+## Task List
+
+### Phase 1: Foundation
+- [ ] Task 1: ...
+- [ ] Task 2: ...
+
+### Checkpoint: Phase 1
+- [ ] Tests pass, lint/formatter clean (module-specific commands)
+
+### Phase 2: Core Features
+- [ ] Task 3: ...
+- [ ] Task 4: ...
+
+### Checkpoint: Phase 2
+- [ ] End-to-end flow works
+
+### Phase 3: Polish
+- [ ] Task 5: ...
+- [ ] Task 6: ...
+
+### Checkpoint: Complete
+- [ ] All acceptance criteria met
+- [ ] Ready for review
+
+## Testing Strategy
+[How to verify: which test commands to run per module, what cases to cover,
+manual verification steps, lint/format checks. Consult each module's core
+memory for the exact commands.]
+
+## Parallelization Opportunities
+- **Safe to parallelize:** Independent feature slices across separate
+  modules, tests for already-implemented features
+- **Must be sequential:** Shared common schema changes, database migrations
+- **Needs coordination:** Features that share a contract (define the contract
+  first, then parallelize)
+
+## Open Questions
+- [Question needing human input]
+```
+
+When the plan is purely analytical (e.g. a code review or feasibility study
+with no implementation), skip the **Approach** and **Task List** sections and
+lead with **Findings** instead, keeping the rest of the structure.
+
+## Verification Checklist
+
+Before starting implementation, confirm:
+
+- [ ] Every task has acceptance criteria
+- [ ] Every task has a verification step
+- [ ] Task dependencies are identified and ordered correctly
+- [ ] No task touches more than ~5 files
+- [ ] Checkpoints exist between major phases
+- [ ] The human has reviewed and approved the plan

+# Refine Prompt
+
+Expert prompt-engineering pass on a user-supplied prompt. Takes a draft prompt
+and returns a clearer, more effective, well-structured version — ready to be
+used with any AI model. Never executes the prompt itself.
+
+## When to Use
+
+- The user shares a prompt and asks to improve, refine, polish, or rewrite it.
+- The user asks "make this prompt better" or "can you clean this up?".
+- The user wants to add structure, constraints, examples, or output format to
+  a vague prompt.
+- The user wants a prompt adapted for a specific target model, audience, or
+  task type.
+
+Do **not** use this skill to actually answer the prompt or do the task — it
+only rewrites the prompt.
+
+## Role
+
+You are an expert Prompt Engineer with strong knowledge of Penpot. Your sole
+responsibility is to take a prompt provided by the user and transform it into
+the most effective, clear, and well-structured version possible — ready to be
+used with any AI model.
+
+You do **not** execute tasks. You do **not** write code. You only design and
+refine prompts.
+
+## Required Reading Before Refining
+
+Before rewriting, internalize the project context the prompt will likely run
+against:
+
+1. Read `AGENTS.md` (root) for the project-level rules and conventions.
+2. Read `.serena/memories/critical-info.md` (or the equivalent entry point) to
+   understand the module layout (`frontend`, `backend`, `common`,
+   `render-wasm`, `exporter`, `mcp`, `plugins`, `library`).
+3. Skim the relevant module's core memory (`mem:frontend/core`,
+   `mem:backend/core`, etc.) when the prompt targets a specific module — this
+   lets you inject precise vocabulary, file conventions, and test commands
+   into the refined prompt.
+
+This step matters most when the user is preparing a prompt *about* the
+Penpot codebase. For generic prompts, focus on prompt-engineering principles
+and only weave in Penpot context when it is clearly relevant.
+
+## Requirements
+
+- Analyze the original prompt: identify its intent, target audience,
+  ambiguities, missing context, and structural weaknesses.
+- Ask clarifying questions if the intent is unclear or if critical information
+  is missing (e.g. target model, expected output format, tone, constraints).
+  Keep questions concise and grouped. Prefer to ask 1–4 questions at once
+  rather than one at a time. **Use the `question` tool** to ask them so the
+  user gets a structured multi-choice UI; reserve a plain `## Clarifying
+  questions` markdown section for cases where the `question` tool is
+  unavailable or the question is genuinely open-ended.
+- Rewrite the prompt using prompt-engineering best practices (see below).
+- Preserve the user's original intent — do not change the underlying task.
+- When the user provides Penpot project context, weave in the relevant
+  conventions, module paths, and tooling.
+
+## Prompt Engineering Principles
+
+Apply these techniques when refining prompts:
+
+- **Be specific and explicit**: Replace vague instructions with precise ones.
+- **Set the context**: Include background information the model needs to
+  perform well.
+- **Specify the output format**: State the desired structure, length, tone,
+  or format (e.g. bullet list, JSON, step-by-step).
+- **Add constraints**: Include what the model should avoid or not do.
+- **Use examples** (few-shot): When applicable, suggest adding examples to
+  anchor the model's behaviour.
+- **Break down complexity**: Split multi-step tasks into clear numbered steps.
+- **Avoid ambiguity**: Remove pronouns and references that could be
+  misinterpreted.
+- **Chain of thought**: For reasoning tasks, include "Think step by step."
+- **Role framing**: When helpful, give the model a clear role
+  ("You are a senior backend engineer...").
+- **Tool awareness**: When the prompt targets an agentic model, mention
+  relevant tools (`grep`, `glob`, `read`, `bash`, etc.) so the model uses the
+  right surface.
+
+## Constraints
+
+- Do **not** execute the prompt yourself.
+- Do **not** answer the question inside the prompt.
+- Do **not** add unnecessary verbosity — prompts should be as short as they
+  can be while remaining complete.
+- Always preserve the user's original intent.
+- If the user provides Penpot project context, prefer Penpot-specific
+  vocabulary over generic terms (e.g. name actual modules and `mem:`
+  references instead of "the codebase").
+
+## Output Format
+
+Deliver the result in the response as two clearly separated blocks:
+
+1. **Refined prompt** — a single fenced code block (markdown ```) containing
+   the rewritten prompt, ready to copy and use.
+2. **What changed (brief)** — a short bulleted list of the most important
+   changes you made and why (3–7 bullets max). Skip the rationale if the
+   changes are trivial.
+
+If you asked clarifying questions via the `question` tool, stop and wait for
+the answers before producing a refined prompt. If the `question` tool was not
+available and you asked the questions in chat, list them in a separate
+**Clarifying questions** section above the refined prompt and stop — do not
+produce a refined prompt until the user answers. If the user explicitly told
+you to proceed without questions (e.g. "just rewrite it"), make reasonable
+assumptions and note them under **Assumptions made** in the rationale block.
+
+## File Persistence
+
+Always persist the refined prompt to disk so it can be re-used later, versioned
+in git, and shared with other agents. The response still contains the prompt
+and rationale blocks; the file is an additional artifact, not a replacement.
+
+- Save the refined prompt (the body inside the fenced code block, **without**
+  the surrounding ``` fences) to `.opencode/prompts/<descriptive-name>.md`.
+- Use a **kebab-case** filename that summarises the task, e.g.
+  `add-error-reports-management-rpc.md`, `backend-rpc-security-audit.md`. No
+  spaces, no uppercase, no version numbers or dates in the filename.
+- If `.opencode/prompts/` does not exist, create it before writing.
+- If a file with the same name already exists, overwrite it (the file is the
+  refined prompt, not a log).
+- Only skip the file write when the user explicitly opts out (e.g. "don't save
+  this one", "just show it in the chat"). When in doubt, save it.

+name: security-and-hardening
+description: Hardens code against vulnerabilities. Use when handling user input, authentication, data storage, or external integrations. Use when building any feature that accepts untrusted data, manages user sessions, or interacts with third-party services.
+---
+
+# Security and Hardening
+
+## Overview
+
+Security-first development practices for web applications. Treat every external input as hostile, every secret as sacred, and every authorization check as mandatory. Security isn't a phase — it's a constraint on every line of code that touches user data, authentication, or external systems.
+
+## When to Use
+
+- Building anything that accepts user input
+- Implementing authentication or authorization
+- Storing or transmitting sensitive data
+- Integrating with external APIs or services
+- Adding file uploads, webhooks, or callbacks
+- Handling payment or PII data
+
+## Process: Threat Model First
+
+Controls bolted on without a threat model are guesses. Before hardening, spend five minutes thinking like an attacker:
+
+1. **Map the trust boundaries.** Where does untrusted data cross into your system? HTTP requests, form fields, file uploads, webhooks, third-party APIs, message queues, and **LLM output**. Every boundary is attack surface.
+2. **Name the assets.** What's worth stealing or breaking? Credentials, PII, payment data, admin actions, money movement.
+3. **Run STRIDE over each boundary** — a quick lens, not a ceremony:
+
+| Threat | Ask | Typical mitigation |
+|---|---|---|
+| **S**poofing | Can someone impersonate a user/service? | Authentication, signature verification |
+| **T**ampering | Can data be altered in transit or at rest? | Integrity checks, parameterized queries, HTTPS |
+| **R**epudiation | Can an action be denied later? | Audit logging of security events |
+| **I**nformation disclosure | Can data leak? | Encryption, field allowlists, generic errors |
+| **D**enial of service | Can it be overwhelmed? | Rate limiting, input size caps, timeouts |
+| **E**levation of privilege | Can a user gain rights they shouldn't? | Authorization checks, least privilege |
+
+4. **Write abuse cases next to use cases.** For each feature, ask "how would I misuse this?" — then make that your first test.
+
+If you can't name the trust boundaries for a feature, you're not ready to secure it. This is OWASP **A04: Insecure Design** — most breaches begin in design, not code.
+
+## The Three-Tier Boundary System
+
+### Always Do (No Exceptions)
+
+- **Validate all external input** at the system boundary (API routes, form handlers)
+- **Parameterize all database queries** — never concatenate user input into SQL
+- **Encode output** to prevent XSS (use framework auto-escaping, don't bypass it)
+- **Use HTTPS** for all external communication
+- **Hash passwords** with bcrypt/scrypt/argon2 (never store plaintext)
+- **Set security headers** (CSP, HSTS, X-Frame-Options, X-Content-Type-Options)
+- **Use httpOnly, secure, sameSite cookies** for sessions
+- **Run `npm audit`** (or equivalent) before every release
+
+### Ask First (Requires Human Approval)
+
+- Adding new authentication flows or changing auth logic
+- Storing new categories of sensitive data (PII, payment info)
+- Adding new external service integrations
+- Changing CORS configuration
+- Adding file upload handlers
+- Modifying rate limiting or throttling
+- Granting elevated permissions or roles
+
+### Never Do
+
+- **Never commit secrets** to version control (API keys, passwords, tokens)
+- **Never log sensitive data** (passwords, tokens, full credit card numbers)
+- **Never trust client-side validation** as a security boundary
+- **Never disable security headers** for convenience
+- **Never use `eval()` or `innerHTML`** with user-provided data
+- **Never store sessions in client-accessible storage** (localStorage for auth tokens)
+- **Never expose stack traces** or internal error details to users
+
+## OWASP Top 10 Prevention Patterns
+
+These are prevention patterns, not a ranking. For the 2021 ordering, see the quick-reference table in `references/security-checklist.md`.
+
+### Injection (SQL, NoSQL, OS Command)
+
+```typescript
+// BAD: SQL injection via string concatenation
+const query = `SELECT * FROM users WHERE id = '${userId}'`;
+
+// GOOD: Parameterized query
+const user = await db.query('SELECT * FROM users WHERE id = $1', [userId]);
+
+// GOOD: ORM with parameterized input
+const user = await prisma.user.findUnique({ where: { id: userId } });
+```
+
+### Broken Authentication
+
+```typescript
+// Password hashing
+import { hash, compare } from 'bcrypt';
+
+const SALT_ROUNDS = 12;
+const hashedPassword = await hash(plaintext, SALT_ROUNDS);
+const isValid = await compare(plaintext, hashedPassword);
+
+// Session management
+app.use(session({
+  secret: process.env.SESSION_SECRET,  // From environment, not code
+  resave: false,
+  saveUninitialized: false,
+  cookie: {
+    httpOnly: true,     // Not accessible via JavaScript
+    secure: true,       // HTTPS only
+    sameSite: 'lax',    // CSRF protection
+    maxAge: 24 * 60 * 60 * 1000,  // 24 hours
+  },
+}));
+```
+
+### Cross-Site Scripting (XSS)
+
+```typescript
+// BAD: Rendering user input as HTML
+element.innerHTML = userInput;
+
+// GOOD: Use framework auto-escaping (React does this by default)
+return <div>{userInput}</div>;
+
+// If you MUST render HTML, sanitize first
+import DOMPurify from 'dompurify';
+const clean = DOMPurify.sanitize(userInput);
+```
+
+### Broken Access Control
+
+```typescript
+// Always check authorization, not just authentication
+app.patch('/api/tasks/:id', authenticate, async (req, res) => {
+  const task = await taskService.findById(req.params.id);
+
+  // Check that the authenticated user owns this resource
+  if (task.ownerId !== req.user.id) {
+    return res.status(403).json({
+      error: { code: 'FORBIDDEN', message: 'Not authorized to modify this task' }
+    });
+  }
+
+  // Proceed with update
+  const updated = await taskService.update(req.params.id, req.body);
+  return res.json(updated);
+});
+```
+
+### Security Misconfiguration
+
+```typescript
+// Security headers (use helmet for Express)
+import helmet from 'helmet';
+app.use(helmet());
+
+// Content Security Policy
+app.use(helmet.contentSecurityPolicy({
+  directives: {
+    defaultSrc: ["'self'"],
+    scriptSrc: ["'self'"],
+    styleSrc: ["'self'", "'unsafe-inline'"],  // Tighten if possible
+    imgSrc: ["'self'", 'data:', 'https:'],
+    connectSrc: ["'self'"],
+  },
+}));
+
+// CORS — restrict to known origins
+app.use(cors({
+  origin: process.env.ALLOWED_ORIGINS?.split(',') || 'http://localhost:3000',
+  credentials: true,
+}));
+```
+
+### Sensitive Data Exposure
+
+```typescript
+// Never return sensitive fields in API responses
+function sanitizeUser(user: UserRecord): PublicUser {
+  const { passwordHash, resetToken, ...publicFields } = user;
+  return publicFields;
+}
+
+// Use environment variables for secrets
+const API_KEY = process.env.STRIPE_API_KEY;
+if (!API_KEY) throw new Error('STRIPE_API_KEY not configured');
+```
+
+### Server-Side Request Forgery (SSRF)
+
+Any time the server fetches a URL the user influenced — webhooks, "import from URL", image proxies, link previews — an attacker can aim it at internal services (cloud metadata, `localhost`, private IPs).
+
+```typescript
+// BAD: fetch whatever the user gives you
+await fetch(req.body.webhookUrl);
+
+// GOOD: allowlist scheme + host, reject if ANY resolved IP is private, forbid redirects
+import { lookup } from 'node:dns/promises';
+import ipaddr from 'ipaddr.js';
+
+const ALLOWED_HOSTS = new Set(['hooks.example.com']);
+
+async function assertSafeUrl(raw: string): Promise<URL> {
+  const url = new URL(raw);
+  if (url.protocol !== 'https:') throw new Error('https only');
+  if (!ALLOWED_HOSTS.has(url.hostname)) throw new Error('host not allowed');
+  // Resolve ALL records; a single private/reserved address fails the check.
+  const addrs = await lookup(url.hostname, { all: true });
+  if (addrs.some((a) => ipaddr.parse(a.address).range() !== 'unicast')) {
+    throw new Error('private/reserved IP');
+  }
+  return url;
+}
+
+await fetch(await assertSafeUrl(req.body.webhookUrl), { redirect: 'error' });
+```
+
+The `range() !== 'unicast'` check covers loopback, link-local `169.254.169.254` (cloud metadata, the #1 SSRF target), private, and unique-local ranges across IPv4 and IPv6.
+
+**Caveat — this still has a TOCTOU gap.** `fetch` resolves DNS again after the check, so an attacker using a short-TTL record can rebind to an internal IP between validation and connection. For high-risk surfaces, resolve once and connect to the pinned IP, or put a filtering agent in front (`request-filtering-agent` / `ssrf-req-filter`).
+
+## Input Validation Patterns
+
+### Schema Validation at Boundaries
+
+```typescript
+import { z } from 'zod';
+
+const CreateTaskSchema = z.object({
+  title: z.string().min(1).max(200).trim(),
+  description: z.string().max(2000).optional(),
+  priority: z.enum(['low', 'medium', 'high']).default('medium'),
+  dueDate: z.string().datetime().optional(),
+});
+
+// Validate at the route handler
+app.post('/api/tasks', async (req, res) => {
+  const result = CreateTaskSchema.safeParse(req.body);
+  if (!result.success) {
+    return res.status(422).json({
+      error: {
+        code: 'VALIDATION_ERROR',
+        message: 'Invalid input',
+        details: result.error.flatten(),
+      },
+    });
+  }
+  // result.data is now typed and validated
+  const task = await taskService.create(result.data);
+  return res.status(201).json(task);
+});
+```
+
+### File Upload Safety
+
+```typescript
+// Restrict file types and sizes
+const ALLOWED_TYPES = ['image/jpeg', 'image/png', 'image/webp'];
+const MAX_SIZE = 5 * 1024 * 1024; // 5MB
+
+function validateUpload(file: UploadedFile) {
+  if (!ALLOWED_TYPES.includes(file.mimetype)) {
+    throw new ValidationError('File type not allowed');
+  }
+  if (file.size > MAX_SIZE) {
+    throw new ValidationError('File too large (max 5MB)');
+  }
+  // Don't trust the file extension — check magic bytes if critical
+}
+```
+
+## Triaging npm audit Results
+
+Not all audit findings require immediate action. Use this decision tree:
+
+```
+npm audit reports a vulnerability
+├── Severity: critical or high
+│   ├── Is the vulnerable code reachable in your app?
+│   │   ├── YES --> Fix immediately (update, patch, or replace the dependency)
+│   │   └── NO (dev-only dep, unused code path) --> Fix soon, but not a blocker
+│   └── Is a fix available?
+│       ├── YES --> Update to the patched version
+│       └── NO --> Check for workarounds, consider replacing the dependency, or add to allowlist with a review date
+├── Severity: moderate
+│   ├── Reachable in production? --> Fix in the next release cycle
+│   └── Dev-only? --> Fix when convenient, track in backlog
+└── Severity: low
+    └── Track and fix during regular dependency updates
+```
+
+**Key questions:**
+- Is the vulnerable function actually called in your code path?
+- Is the dependency a runtime dependency or dev-only?
+- Is the vulnerability exploitable given your deployment context (e.g., a server-side vulnerability in a client-only app)?
+
+When you defer a fix, document the reason and set a review date.
+
+### Supply-Chain Hygiene
+
+`npm audit` catches known CVEs; it won't catch a malicious or typosquatted package. Also:
+
+- **Commit the lockfile** and install with `npm ci` (not `npm install`) in CI — reproducible builds, no silent version drift.
+- **Review new dependencies before adding them** — maintenance, download counts, and whether they truly earn their place. Every dependency is attack surface (OWASP **A06: Vulnerable Components**, **LLM03: Supply Chain**).
+- **Be wary of `postinstall` scripts** in unfamiliar packages — they run arbitrary code at install time.
+- **Watch for typosquats** — `cross-env` vs `crossenv`, `react-dom` vs `reactdom`.
+
+## Rate Limiting
+
+```typescript
+import rateLimit from 'express-rate-limit';
+
+// General API rate limit
+app.use('/api/', rateLimit({
+  windowMs: 15 * 60 * 1000, // 15 minutes
+  max: 100,                   // 100 requests per window
+  standardHeaders: true,
+  legacyHeaders: false,
+}));
+
+// Stricter limit for auth endpoints
+app.use('/api/auth/', rateLimit({
+  windowMs: 15 * 60 * 1000,
+  max: 10,  // 10 attempts per 15 minutes
+}));
+```
+
+## Secrets Management
+
+```
+.env files:
+  ├── .env.example  → Committed (template with placeholder values)
+  ├── .env          → NOT committed (contains real secrets)
+  └── .env.local    → NOT committed (local overrides)
+
+.gitignore must include:
+  .env
+  .env.local
+  .env.*.local
+  *.pem
+  *.key
+```
+
+**Always check before committing:**
+```bash
+# Check for accidentally staged secrets
+git diff --cached | grep -i "password\|secret\|api_key\|token"
+```
+
+**If a secret is ever committed, rotate it.** Deleting the line or rewriting history is not enough — assume it's compromised the moment it reaches a remote. Revoke and reissue the key first, then purge it from history.
+
+## Securing AI / LLM Features
+
+If your app calls an LLM — chatbots, summarizers, agents, RAG — it inherits a new attack surface. Map it to the [OWASP Top 10 for LLM Applications (2025)](https://genai.owasp.org/llm-top-10/):
+
+- **Treat all model output as untrusted input (LLM05: Improper Output Handling).** Never pass LLM output straight into `eval`, SQL, a shell, `innerHTML`, or a file path. Validate and encode it exactly as you would raw user input.
+- **Assume prompts can be hijacked (LLM01: Prompt Injection).** Untrusted text in the context window — a user message, a fetched web page, a PDF — can carry instructions. The system prompt is not a security boundary; enforce permissions in code, not in the prompt.
+- **Keep secrets and other users' data out of prompts (LLM02 / LLM07).** Anything in the context can be echoed back. Don't put API keys, cross-tenant data, or the full system prompt where the model can repeat it.
+- **Constrain tool and agent permissions (LLM06: Excessive Agency).** Scope tools to the minimum, require confirmation for destructive or irreversible actions, and validate every tool argument.
+- **Bound consumption (LLM10: Unbounded Consumption).** Cap tokens, request rate, and loop/recursion depth so a crafted input can't run up cost or hang the system.
+- **Isolate retrieval data (LLM08: Vector and Embedding Weaknesses).** In RAG, treat the vector store as a trust boundary: partition embeddings per tenant so one user can't retrieve another's data, and validate documents before indexing so poisoned content can't steer answers.
+
+```typescript
+// BAD: trusting model output as a command or as markup
+const sql = await llm.generate(`Write SQL for: ${userQuestion}`);
+await db.query(sql);                                   // arbitrary query execution
+container.innerHTML = await llm.reply(userMessage);   // stored XSS, via the model
+
+// GOOD: model output is data — parse defensively, then validate, then encode
+let intent;
+try {
+  intent = CommandSchema.parse(JSON.parse(await llm.replyJson(userMessage)));
+} catch {
+  throw new ValidationError('unexpected model output'); // JSON.parse or schema failed
+}
+await runAllowlistedAction(intent.action, intent.params);
+container.textContent = await llm.reply(userMessage);
+```
+
+## Security Review Checklist
+
+```markdown
+### Authentication
+- [ ] Passwords hashed with bcrypt/scrypt/argon2 (salt rounds ≥ 12)
+- [ ] Session tokens are httpOnly, secure, sameSite
+- [ ] Login has rate limiting
+- [ ] Password reset tokens expire
+
+### Authorization
+- [ ] Every endpoint checks user permissions
+- [ ] Users can only access their own resources
+- [ ] Admin actions require admin role verification
+
+### Input
+- [ ] All user input validated at the boundary
+- [ ] SQL queries are parameterized
+- [ ] HTML output is encoded/escaped
+- [ ] Server-side URL fetches are allowlisted (no SSRF to internal services)
+
+### Data
+- [ ] No secrets in code or version control
+- [ ] Sensitive fields excluded from API responses
+- [ ] PII encrypted at rest (if applicable)
+
+### Infrastructure
+- [ ] Security headers configured (CSP, HSTS, etc.)
+- [ ] CORS restricted to known origins
+- [ ] Dependencies audited for vulnerabilities
+- [ ] Error messages don't expose internals
+
+### Supply Chain
+- [ ] Lockfile committed; CI installs with `npm ci`
+- [ ] New dependencies reviewed (maintenance, downloads, postinstall scripts)
+
+### AI / LLM (if used)
+- [ ] Model output treated as untrusted (no eval/SQL/innerHTML/shell)
+- [ ] Secrets and other users' data kept out of prompts
+- [ ] Tool/agent permissions scoped; destructive actions require confirmation
+```
+## Common Rationalizations
+
+| Rationalization | Reality |
+|---|---|
+| "This is an internal tool, security doesn't matter" | Internal tools get compromised. Attackers target the weakest link. |
+| "We'll add security later" | Security retrofitting is 10x harder than building it in. Add it now. |
+| "No one would try to exploit this" | Automated scanners will find it. Security by obscurity is not security. |
+| "The framework handles security" | Frameworks provide tools, not guarantees. You still need to use them correctly. |
+| "It's just a prototype" | Prototypes become production. Security habits from day one. |
+| "Threat modeling is overkill here" | Five minutes of "how would I attack this?" prevents the design flaws no control can patch later. |
+| "It's just LLM output, it's only text" | That "text" can be a SQL statement, a script tag, or a shell command. Treat it like any untrusted input. |
+
+## Red Flags
+
+- User input passed directly to database queries, shell commands, or HTML rendering
+- Secrets in source code or commit history
+- API endpoints without authentication or authorization checks
+- Missing CORS configuration or wildcard (`*`) origins
+- No rate limiting on authentication endpoints
+- Stack traces or internal errors exposed to users
+- Dependencies with known critical vulnerabilities
+- Server fetches user-supplied URLs without an allowlist (SSRF)
+- LLM/model output passed into a query, the DOM, a shell, or `eval`
+- Secrets, PII, or the full system prompt placed inside an LLM context window
+
+## Verification
+
+After implementing security-relevant code:
+
+- [ ] `npm audit` shows no critical or high vulnerabilities
+- [ ] No secrets in source code or git history
+- [ ] All user input validated at system boundaries
+- [ ] Authentication and authorization checked on every protected endpoint
+- [ ] Security headers present in response (check with browser DevTools)
+- [ ] Error responses don't expose internal details
+- [ ] Rate limiting active on auth endpoints
+- [ ] Server-side URL fetches validated against an allowlist (no SSRF)
+- [ ] LLM/model output validated and encoded before use (if AI features present)

+metadata: {"clawdbot":{"requires":{"bins":["python3"]}}}
+---
+
+# Taiga API Skill
+
+Fetch information from Taiga public API for the **Penpot** project
+(project id: `345963`, slug: `penpot`).
+
+**No authentication required** — only public project data is accessed.
+
+## Prerequisites
+
+- `python3` — the `tools/taiga.py` CLI script is self-contained (stdlib only)
+
+## Quick Start
+
+The easiest way is to use the bundled Python script:
+
+```bash
+# Pass a Taiga URL directly
+python3 tools/taiga.py https://tree.taiga.io/project/penpot/issue/13714
+
+# Or use "<type> <ref>" syntax
+python3 tools/taiga.py us 14128
+python3 tools/taiga.py task 13648
+
+# Add --json for raw output
+python3 tools/taiga.py --json issue 13714
+
+# See full usage
+python3 tools/taiga.py --help
+```
+
+## URL Pattern Reference
+
+Taiga web URLs follow these patterns:
+
+| Type | Web URL Pattern |
+|------|----------------|
+| Issue | `https://tree.taiga.io/project/penpot/issue/<REF>` |
+| User Story | `https://tree.taiga.io/project/penpot/us/<REF>` |
+| Task | `https://tree.taiga.io/project/penpot/task/<REF>` |
+
+To extract the **type** and **ref** from a URL:
+- `issue/13714` → type=`issue`, ref=`13714`
+- `us/14128` → type=`us`, ref=`14128`
+- `task/13648` → type=`task`, ref=`13648`
+
+## Python Script Reference
+
+The `tools/taiga.py` script wraps the Taiga API into a single convenient CLI
+with sensible defaults.
+
+### Usage
+
+```
+python3 tools/taiga.py <taiga-url>
+python3 tools/taiga.py <type> <ref>
+python3 tools/taiga.py [--json] <taiga-url>
+python3 tools/taiga.py [--json] <type> <ref>
+```
+
+### Examples
+
+```bash
+# By URL (recommended — no need to think about type/ref)
+python3 tools/taiga.py https://tree.taiga.io/project/penpot/issue/13714
+
+# By type and ref
+python3 tools/taiga.py us 14128
+python3 tools/taiga.py task 13648
+
+# Raw JSON output
+python3 tools/taiga.py --json issue 13714
+```
+
+### Output
+
+The script prints a clean, structured summary:
+
+```text

+name: update-changelog
+description: Update the project CHANGES.md with issues from a given GitHub milestone, with correct categorization and references.
+---
+
+# Skill: update-changelog
+
+Update `CHANGES.md` with entries for all issues and PRs in a given GitHub
+milestone. Each entry references the user-facing issue (not the PR) as the
+primary link, with the fix PR inline on the same line.
+
+## When to Use
+
+- Before a new release, to populate the changelog with all fixed issues
+- When new issues are added to an existing milestone and the changelog needs
+  to be refreshed
+- To ensure every entry follows the correct format for the changelog
+
+## Prerequisites
+
+- `gh` CLI authenticated (`gh auth status`)
+- Python 3.8+
+- `tools/gh.py` helper script available
+
+## Workflow
+
+### 1. Determine the target version
+
+The version is typically a semver string like `2.15.3`. Confirm with the user
+if not specified.
+
+### 2. Fetch all issues in the milestone
+
+Use the helper script. It uses GraphQL for efficient single-pass fetching
+(closing PRs are included in the same query — no N+1):
+
+```bash
+# All closed issues (default)
+python3 tools/gh.py issues "2.16.0"
+
+# Include open issues too
+python3 tools/gh.py issues "2.16.0" --state all
+
+# Exclude entries that should not go in the changelog
+python3 tools/gh.py issues "2.16.0" --exclude "release blocker,no changelog"
+```
+
+**Exclusion rules (issue-level):**
+- `no changelog` label — Chore/refactor work that doesn't need a changelog entry
+- `release blocker` label — Blocked issues not yet ready for changelog
+- `Task` issue type — Internal chores are not user-facing; automatically excluded by `gh.py`. Use `--include-tasks` to override.
+- **Rejected project status** — Issues with a "Rejected" status in the "Main" project board are automatically excluded by `gh.py`. This project-level status (independent of the GitHub issue `state`) indicates the issue was rejected from the release. Use `--include-rejected` to override.
+
+**Exclusion rules (PR-level):**
+In addition to issue-level exclusions, PRs with these labels should be
+excluded regardless of their linked issue's labels:
+- `release blocker` — PR is part of a pending release blocker batch
+- `no issue required` — Trivial fix not tracked as an issue
+
+The script outputs JSON with each entry containing `number`, `title`, `state`,
+`issue_type`, `labels`, `closing_prs` (the PRs that fix each issue), and
+`project_status` (the "Main" project board status, e.g. "Done", "Rejected",
+or `null` if not tracked in a project).
+
+### 3. Identify missing entries (optional)
+
+If updating from an existing `CHANGES.md`, find issues in the milestone that
+are NOT yet referenced in the changelog:
+
+```bash
+python3 tools/gh.py issues "2.16.0" --exclude "release blocker,no changelog" --compare CHANGES.md
+```
+
+This returns a filtered JSON array with only the missing issues.
+
+> **Note:** The `--compare` flag checks **issues** only (via issue number
+> references in the changelog). To find merged **PRs** not yet referenced,
+> use the milestone PR cross-reference described in step 10 below.
+
+### 4. Fetch additional PR details when needed
+
+When you need more context for specific PRs (e.g. to find the PR author for
+community contribution attribution, or to read the PR body for
+"Fixes/Closes #NNN" patterns):
+
+```bash
+# One or more PR numbers
+python3 tools/gh.py prs 9179 9204 9311
+
+# From a file
+python3 tools/gh.py prs --file prs.txt
+
+# From stdin
+cat prs.txt | python3 tools/gh.py prs --stdin
+```
+
+The `prs` command also supports listing all PRs in a milestone in one call:
+
+```bash
+# All merged PRs in a milestone (default)
+python3 tools/gh.py prs --milestone "2.16.0"
+
+# All states (merged, open, closed)
+python3 tools/gh.py prs --milestone "2.16.0" --state all
+```
+
+The `prs` command returns JSON with `number`, `title`, `body`, `state`,
+`merged_at`, `author`, `labels`, and `closing_issues`. PRs are fetched in
+batches of 50 via GraphQL to stay within API limits (milestone mode uses
+paginated GraphQL on the milestone's `pullRequests` connection).
+
+You can also list all PRs in a milestone in a single call:
+
+```bash
+# All merged PRs in a milestone (default)
+python3 tools/gh.py prs --milestone "2.16.0"
+
+# All states (merged, open, closed)
+python3 tools/gh.py prs --milestone "2.16.0" --state all
+
+# Open PRs only
+python3 tools/gh.py prs --milestone "2.16.0" --state open
+```
+
+The milestone path uses paginated GraphQL on the milestone's `pullRequests`
+connection (100 per page), avoiding one-by-one fetches.
+
+### 5. Categorize entries — strictly by issue type, never by labels or emoji
+
+Use the **Issue Type** field (GitHub's native issue type, exposed as
+`issue_type` in the `gh.py` JSON output) to determine which section an entry
+belongs to.
+
+> **⚠️ CRITICAL: Never use labels or title emoji prefixes for categorization.**
+> Labels like `bug` and `enhancement`, as well as title prefixes like `:bug:`
+> and `:sparkles:`, are frequently inaccurate, missing, or contradictory to the
+> actual issue type. The `issue_type` field from `gh.py` is the single source
+> of truth.
+
+| `issue_type` value | Changelog section |
+|--------------------|-------------------|
+| `Bug` | `### :bug: Bugs fixed` |
+| `Feature` or `Enhancement` | `### :sparkles: New features & Enhancements` |
+| `Task` | **Exclude** — internal chores are not user-facing |
+| `null` (not set) | Check labels as a fallback: `bug` label → bugs, otherwise enhancements |
+
+The `gh.py` issues command already includes `issue_type` in every entry's
+output. **No separate GraphQL query is needed.**
+
+**Community contribution attribution:** If the issue or its fix PR has the
+`community contribution` label, add an attribution `(by @<github_username>)`
+on the changelog entry line, **before** the GitHub issue/PR references.
+
+The attribution should reference the **PR author**, not the issue author.
+The `prs` subcommand includes the `author` field — use that:
+
+```bash
+python3 tools/gh.py prs <PR_NUMBER> | python3 -c "import sys,json; print(json.load(sys.stdin)[0]['author'])"
+```
+
+Placement in the entry line:
+```markdown
+- Fix description of the bug (by @username) [#<ISSUE>](...) (PR: [#<PR>](...))
+```
+
+**Only closed issues are included.** An issue must have `state: "closed"` to
+appear in the changelog. Open/unresolved issues are omitted, even if they are
+tracked in the milestone.
+
+**Pairing rules:**
+
+| Pattern | Changelog format |
+|---------|-----------------|
+| Closed issue + one or more PRs fix it | Primary link = issue, PR inline comma-separated |
+| PR exists with no linked issue | If a corresponding closed issue exists in the same milestone, link the issue. Otherwise, skip the entry (the issue must be the changelog unit). |
+| Closed issue with no fix PR in milestone | Link the issue directly, without a PR reference. |
+
+> **False-positive associations:** A PR may incorrectly claim to close an issue
+> from a different context (e.g., a very old PR referencing a modern issue, or a
+> cross-project reference). If the PR title and issue title are clearly unrelated,
+> or the PR was created years before the issue, treat it as a data glitch and
+> skip it. PR [#3](https://github.com/penpot/penpot/pull/3) (ancient License PR
+> claiming to close a plugin API issue) is a known example.
+
+### 5a. ⚠️ Verify PR merge status before writing
+
+A closed issue may list closing PRs that were **closed without merging**
+(e.g., a community PR that was superseded by another). The changelog must
+only reference **merged** PRs. Verify before writing:
+
+```bash
+# Collect all PR numbers from the candidate entries and check them
+python3 tools/gh.py prs <ALL_PR_NUMBERS> | python3 -c "
+import json, sys
+for pr in json.load(sys.stdin):
+    if pr['state'] != 'MERGED':
+        print(f'WARNING: #{pr[\"number\"]} is {pr[\"state\"]} (not merged)')
+"
+```
+
+If a closing PR is closed-unmerged, find the actual merged PR that
+superseded it:
+1. Check the issue's closing PRs list for other PRs (there may be multiple)
+2. Look for other PRs with similar titles or descriptions referencing the same issue
+3. Inspect the closed PR's conversation timeline for a pointer to the replacement
+
+Replace the reference in the changelog entry with the correct merged PR number.
+
+### 6. Read the current CHANGES.md
+
+Read the top of `CHANGES.md` to understand the existing format and find the
+insertion point (newest version goes at the top, after the `# CHANGELOG`
+header).
+
+Key format rules from the existing file:
+
+```markdown
+## <VERSION>
+
+### :bug: Bugs fixed
+
+- Fix description of the bug [#<ISSUE>](https://github.com/penpot/penpot/issues/<ISSUE>) (PR: [#<PR>](https://github.com/penpot/penpot/pull/<PR>))
+- Fix another bug (by @contributor) [#<ISSUE>](https://github.com/penpot/penpot/issues/<ISSUE>) (PR: [#<PR>](https://github.com/penpot/penpot/pull/<PR>))
+
+### :sparkles: New features & Enhancements
+
+- Add new feature description [#<ISSUE>](https://github.com/penpot/penpot/issues/<ISSUE>) (PR: [#<PR>](https://github.com/penpot/penpot/pull/<PR>))
+```
+
+Format details:
+- Entries start with `- ` followed by a short description in imperative mood
+- Primary link is **always the issue** (user-facing artifact)
+- PR references are inline on the same line: `(PR: [#<N>](<url>))`
+  If an issue has multiple fix PRs, they are comma-separated:
+  `(PR: [#<N>](<url>), [#<M>](<url>))`
+- The description should describe the fix/feature from the user's perspective
+- Community contributions get `(by @<username>)` **before** the issue link
+- Sections are separated by a blank line between the last entry and the next
+  section title
+- Only include a section if there are entries for it
+- When an entry already exists in an earlier version section, it must be removed
+  from the current version to avoid duplicates
+
+### 6a. Pre-flight checks — fix rule violations in the changelog
+
+**The LLM must apply these checks during the workflow and fix any
+violations directly in `CHANGES.md`. They are not anomalies — they are
+process errors that should be corrected before writing the new section.**
+
+The changelog is a *snapshot* of the milestone at a point in time, but
+milestones and changelog entries can drift. The LLM must reconcile the
+existing changelog against the current state of the milestone and the
+existing changelog entries.
+
+For each entry that already exists in `CHANGES.md` (in any version
+section) or in the candidate set for the current milestone, check:
+
+1. **Duplicate across versions.** Is the same issue already documented
+   in another (older) version section? If yes, this is a *backport*:
+   - The user-facing fix was already released. Remove the duplicate
+     from the current section. The earlier version is the canonical
+     reference.
+
+2. **Stale milestone assignment.** Has the issue been moved out of the
+   current milestone since the changelog was last updated (e.g., a fix
+   arrived late and the issue was reassigned to a future milestone)?
+   - Verify the issue is still in the current milestone via
+     `python3 tools/gh.py issues <MILESTONE> --state all`. If it's no
+     longer there, remove the entry from the current section. (If the
+     target section doesn't exist yet, the entry is simply dropped.)
+
+3. **Exclusion labels newly applied.** Did the issue acquire a
+   `no changelog` or `release blocker` label since the changelog was
+   last updated? If yes, remove the entry from the current section.
+
+4. **Issue state changed.** Is the issue still closed? Has it been
+   reopened, deleted, or moved to a `Rejected` project status? If yes,
+   remove the entry.
+
+5. **Unmerged or removed PR references.** For every PR referenced in
+   the entry, is the PR still merged? Was the PR closed without
+   merging (superseded)? Was the PR moved to a different milestone?
+   If the only referenced PR is no longer merged, fix the reference
+   (find the actual merged fix PR) or remove the entry. A PR that is
+   merged in a *different* milestone is reported as an anomaly in
+   step 11 — do not silently remove it.
+
+6. **Issue type changed.** Did the issue type change (e.g., from Bug to
+   Task)? If the new type is `Task`, the issue is internal and should
+   be removed.
+
+7. **Cross-section completeness.** For every closed, non-excluded
+   milestone issue that is *not* referenced in any version section of
+   the changelog, add it to the current section (per the categorization
+   rules in step 5).
+
+After these checks, the changelog should be internally consistent with
+the milestone. **Do not defer these fixes to step 11 — they are
+workflow errors, not anomalies.** Step 11 only reports milestone
+mismatches that require human judgment about the team's release
+intent.
+
+### 7. Build the description text
+
+Derive the description from the issue title, not the PR title. Strip leading
+emoji prefixes (`:bug:`, `:sparkles:`, `:tada:`) and focus on the
+user-facing behavior.
+
+Examples:
+
+| Issue title | Changelog description |
+|-------------|----------------------|
+| `Plugin API token methods fail with schema validation error on PRO` | `Fix Plugin API token methods failing with schema validation error on PRO` |
+| `Comment content is not sanitized before rendering, enabling stored XSS` | `Sanitize comment content on rendering` |
+| `Custom uploaded font family names are not sanitized` | `Sanitize font family names on custom uploaded fonts` |
+
+### 8. Insert the section into CHANGES.md
+
+Insert the new version section right after the `# CHANGELOG` header (before
+the previous version entry). Use the `edit` tool with enough context to make
+a unique match.
+
+### 9. Verify
+
+Read the top of `CHANGES.md` and confirm:
+- The version header is correct
+- Every entry has a GitHub link
+- Entries with a fix PR have the PR sub-line
+- The section ordering is correct (newest first)
+- Formatting matches the surrounding entries
+
+### 10. Cross-reference milestone PRs against the changelog
+
+Issues can be fixed by PRs that aren't in the milestone, and merged PRs in
+the milestone may not close any tracked issue. After writing, run a full
+cross-reference to catch gaps:
+
+```bash
+# List all merged PRs in the milestone
+python3 tools/gh.py prs --milestone "<MILESTONE>" --state merged > /tmp/milestone-prs.json
+
+# Extract PR numbers from the changelog section
+python3 -c "
+import json, re
+
+with open('CHANGES.md') as f:
+    content = f.read()
+
+# Extract the version section (adjust regex to match the actual version)
+match = re.search(r'## <MILESTONE> \(Unreleased\)\n(.*?)(?:\n## |\Z)', content, re.DOTALL)
+section = match.group(1)
+
+# Collect all PR numbers referenced
+changelog_prs = set()
+for m in re.findall(r'\[#(\d+)\]\(https://github\.com/penpot/penpot/pull/\d+\)', section):
+    changelog_prs.add(int(m))
+
+# Collect all milestone PRs (filtered)
+with open('/tmp/milestone-prs.json') as f:
+    milestone_prs = json.load(f)
+
+milestone_merged = {pr['number'] for pr in milestone_prs}
+
+# PRs in milestone but not in changelog
+missing = sorted(milestone_merged - changelog_prs)
+print(f'Milestone merged PRs: {len(milestone_merged)}')
+print(f'Changelog referenced PRs: {len(changelog_prs)}')
+print(f'PRs in milestone but NOT in changelog: {len(missing)}')
+for num in missing:
+    pr = next(p for p in milestone_prs if p['number'] == num)
+    print(f'  #{num} {pr[\"title\"][:80]}')
+"
+```
+
+For each missing PR found, decide whether it should be added to the
+changelog or is legitimately excluded (check its labels).
+
+Also verify that no closed-unmerged PRs remain in the changelog:
+
+```bash
+python3 tools/gh.py prs --milestone "<MILESTONE>" --state all | python3 -c "
+import json, sys
+data = json.load(sys.stdin)
+closed = [p for p in data if p['state'] == 'CLOSED']
+if closed:
+    print('WARNING: CLOSED (unmerged) PRs in milestone:')
+    for p in closed:
+        print(f'  #{p[\"number\"]} {p[\"title\"][:80]}')
+"
+```
+
+**Post-edit audit checklist:**
+- ✅ All referenced PRs are merged (no closed-unmerged artifacts)
+- ✅ Every merged milestone PR is either in the changelog or excluded by label
+- ✅ PR and issue counts are internally consistent
+- ✅ No false-positive PR-to-issue associations
+
+## Version section template
+
+```markdown
+## <VERSION>
+
+### :bug: Bugs fixed
+
+- <fix description> [#<ISSUE>](https://github.com/penpot/penpot/issues/<ISSUE>) (PR: [#<PR>](https://github.com/penpot/penpot/pull/<PR>))
+- <fix description> (by @contributor) [#<ISSUE>](https://github.com/penpot/penpot/issues/<ISSUE>) (PR: [#<PR>](https://github.com/penpot/penpot/pull/<PR>))
+```
+
+### 11. Generate anomaly report and save to CHANGES-ISSUES.md
+
+After all edits and cross-referencing are complete, generate a structured
+report and save it to `CHANGES-ISSUES.md` (overwriting if exists).
+This provides a persistent record of any discrepancies between the milestone
+and the changelog.
+
+**Every issue and PR number in the report must be rendered as a full GitHub
+Markdown link** using the same URL format as `CHANGES.md`:
+- Issue N → `[#N](https://github.com/penpot/penpot/issues/N)`
+- PR N → `[#N](https://github.com/penpot/penpot/pull/N)`
+
+The titles and notes should also link to the corresponding issue/PR page
+where applicable, so the report is self-contained and clickable from any
+Markdown viewer.
+
+## What is an anomaly
+
+**An anomaly is a milestone-mismatch between an issue and its referenced
+PR.** It indicates that the changelog claim "this issue is fixed by this PR,
+all in milestone M" is inconsistent with the actual milestone assignments.
+There are exactly two types:
+
+1. **Issue is in the milestone, but its referenced PR is in a different
+   milestone (or has no milestone).** The changelog claims a fix in this
+   release, but the PR is being released elsewhere — the fix may not
+   actually ship here.
+2. **PR is in the milestone, but the issue it closes is in a different
+   milestone (or has no milestone).** The PR is being released here, but
+   the issue it fixes is being released in a different version (or never
+   tracked in a milestone) — the changelog pairing is misleading.
+
+**Anything else is not an anomaly.** Other discrepancies (exclusion
+labels on in-changelog issues, missing valid issues, unmerged PR
+references, duplicates across versions, stale milestone assignments)
+are **rule violations** that the LLM must fix directly in `CHANGES.md`
+during step 6a (pre-flight checks). They should not appear in this
+report — if they do, the LLM has skipped the pre-flight step and
+needs to re-run the workflow.
+
+The changelog's primary unit is the **issue**, not the PR, so a missing or
+mismatched PR only matters when its issue is part of this milestone.

+This generates `CHANGES-ISSUES.md` containing **only the anomalies** —

+step and needs to re-run the workflow before re-generating the report.
+
+The report is overwritten each time it's generated, reflecting the current
+state of the milestone and changelog. Every number is rendered as a full

+self-contained and clickable in any Markdown viewer.
+
+## Key Principles
+
+- **Issue = changelog unit.** The primary link always points to the
+  user-facing issue, not the implementation PR.
+- **PR = implementation detail.** Reference the PR inline so readers
+  can find the code changes.
+- **Latest version first.** New sections are inserted at the top of the
+  changelog, below the `# CHANGELOG` header.
+- **Issue Type determines section — exclusively.** Use the `issue_type` field from `gh.py` output (Bug → `:bug:`, Feature/Enhancement → `:sparkles:`). **Do not** use labels (`bug`, `enhancement`) or title emoji prefixes (`:bug:`, `:sparkles:`) — they are frequently wrong or contradictory. The `issue_type` is the single source of truth.
+- **User-facing descriptions.** Write from the user's perspective — describe
+  what broke and what was fixed, not internal implementation details.
+- **Community attribution.** When the issue or fix PR has the
+  `community contribution` label, add `(by @<username>)` on the entry line
+  between the description and the issue link. Use the **PR author** (not the
+  issue author) for the attribution.
+- **Only closed issues.** An issue must have `state: "closed"` to appear in
+  the changelog. Open/unresolved issues are omitted.
+- **Rejected project status.** Issues marked as "Rejected" in the "Main"
+  project board are automatically excluded by `gh.py`, even if they are
+  closed. The project status is distinct from the GitHub issue state.
+  Use `--include-rejected` to override this behavior.
+- **Excluded issues.** Issues with `no changelog` label must be excluded.
+  Issues with `issue_type: "Task"` must also be excluded — they are internal
+  chores, not user-facing changes.
+- **Multiple PRs per issue.** If multiple PRs fix the same issue, list them
+  comma-separated inline: `(PR: [#A](url), [#B](url))`.
+- **Duplicate removal.** If an entry already exists in a prior version section,
+  remove it from the current version. Check for text-level duplicates (after
+  stripping links and attributions) across version sections.
+- **Taiga references.** If a changelog entry references a Taiga URL
+  (`tree.taiga.io`), attempt to find a corresponding GitHub issue via the
+  Taiga description text or by searching GitHub PRs that reference the Taiga
+  URL. Replace the Taiga reference with the GitHub issue link and add the PR
+  reference if applicable.
+- **Re-fetch before editing.** Milestones can change — always re-fetch issues
+  before making edits, don't rely on cached data.
+- **Use `tools/gh.py`.** Prefer the helper script over raw `gh api` calls for
+  milestone issue listing and PR detail fetching. It handles GraphQL
+  pagination, batching, and label filtering automatically.
+- **Verify PR merge status.** Not all closing PRs are merged — community PRs
+  can be superseded and closed without merging. Always check that every PR
+  referenced in the changelog has `state: MERGED`.
+- **PR-level exclusions apply.** A PR can carry its own exclusion labels
+  (`release blocker`, `no issue required`) independent of its linked issue's
+  labels. Check both.
+- **Cross-reference milestone PRs, not just issues.** The `--compare` flag on
+  the `issues` command only compares issue numbers. Merged PRs not linked to
+  any milestone issue can be missed. Use `python3 tools/gh.py prs --milestone`
+  for a full PR cross-reference.
+- **False-positive PR-to-issue associations.** A PR may claim to close an
+  issue from a different project or context. If the PR title and issue title
+  are clearly unrelated, or the PR predates the issue by years, treat it as a
+  data glitch and skip it.
+- **Anomaly = milestone mismatch only.** The report contains only milestone
+  mismatches: (1) the issue is in this milestone but the referenced PR is
+  in a different milestone (or unassigned), and (2) the PR is in this
+  milestone but the issue it closes is in a different milestone (or
+  unassigned). These are anomalies because the changelog pairing is
+  *misleading* — the human needs to decide whether the milestone or the
+  changelog is wrong. All other discrepancies (exclusion labels, missing
+  valid issues, unmerged PR references, duplicates, stale milestone
+  assignments) are **rule violations** that the LLM must fix directly in
+  `CHANGES.md` during step 6a (pre-flight checks). They never appear in
+  the report — if they do, the pre-flight step was skipped.

+# Backend Auth, Permissions, and Product Domain Subtleties
+
+## Auth and sessions
+
+- Main auth RPC commands live in `app.rpc.commands.auth`; LDAP and OIDC provider logic live in `app.auth.ldap` and `app.auth.oidc`, with LDAP-specific RPC checks in `app.rpc.commands.ldap`.
+- Public auth endpoints must explicitly set `::rpc/auth false`; RPC auth defaults to enabled. Session cookie creation/deletion is usually attached as an RPC response transform.
+- Basic Penpot registration is token staged: prepare/register creates or verifies temporary tokens, then profile creation/session setup is reused by other auth backends. The frontend `/auth/verify-token` flow is a hub for registration confirmation, email change, and invitation tokens.
+- OIDC-compatible providers share a generic flow: redirect to provider, validate callback/request token, fetch identity data, then login an existing profile or register a new one. Known providers may have hardcoded endpoints; generic OIDC can use discovery/configured endpoints.
+- LDAP login validates credentials against the external directory, fetches identity data, then logs in or registers a matching Penpot profile. LDAP registration is not a separate Penpot signup flow.
+- Logout may return an OIDC provider redirect URI when the session claims include provider/session data and the provider has a logout URI.
+- Invitation tokens are verified through token issuers and only accepted when the token member id/email matches the authenticated profile; otherwise login proceeds without consuming the invitation.
+- HTTP/session parsing details such as cookie/header precedence, JWT session token versions, and SameSite behavior are in `mem:backend/http-storage-filedata-subtleties`.
+
+## Permission model
+
+- `app.rpc.permissions` provides predicate/check factories. Failed permission checks intentionally raise `:not-found` / `:object-not-found`, not an authorization-specific error, to avoid leaking object existence.
+- Team role flags are normalized as owner > admin > editor > viewer. Owner/admin imply edit; any membership row implies read.
+- File/project/comment checks are implemented in the owning command namespaces, often via helpers imported from `files`, `teams`, or `projects`; do not bypass those helpers with direct DB lookups unless preserving their not-found semantics.
+- Comment permission includes both logged-in state and the file/team comment policy. Shared viewer paths may pass `share-id`; preserve that path when changing comment queries.
+
+## Teams, projects, and invitations
+
+- Team/project commands mix DB changes, email, message bus notifications, media/storage cleanup, feature flags, quotas, and audit metadata. Keep mutations transactional when the existing command does so.
+- Invitation flows validate muted/bounced emails before sending and use tokenized invitation state. Accepting an invitation is tied to the invited member identity, not just possession of a token.
+- Logical deletion is used for many product objects; prefer existing logical-deletion helpers over hard deletes unless the command already performs permanent cleanup.
+- Bounced/spam-complaint emails can mute/block a profile for login/registration and email sending. Devenv MailCatcher is the normal local path for registration/email-flow testing.
+
+## Comments, webhooks, and audit
+
+- Comment thread queries join file/project/profile state and exclude deleted files/projects. Unread comment counts depend on `comment_thread_status.modified-at` and profile notification preferences.
+- Webhook edits are allowed for team editors/admins or the webhook creator. Webhook validation performs a synchronous HEAD request with a short timeout; validation errors are mapped through `app.loggers.webhooks`.
+- Audit events are prepared from RPC metadata, result metadata, params, request context, and selected auth identifiers. Webhook event batching can be controlled through audit/webhook metadata on commands or results.
+- Webhook and audit logging are cross-cutting side effects of product commands; when adding a command, check nearby command metadata and result metadata patterns before inventing a new event shape.
+
+## Local testing notes
+
+- Enable LDAP login locally with frontend flag `enable-login-with-ldap`; the devenv includes a configured test LDAP service.
+- OIDC testing requires external provider app credentials plus matching backend/frontend config.
+- Backend domain tests usually live under `backend/test/backend_tests/rpc/commands/*_test.clj` or nearby backend test namespaces. Use focused `clojure -M:dev:test --focus ...` from `backend/` when possible.
+- For auth/session or HTTP behavior, combine backend tests with the HTTP/session notes in `mem:backend/http-storage-filedata-subtleties` because RPC-level tests may not exercise cookie/header transforms.

+# Backend Architecture and Workflow
+
+Backend: JVM Clojure; Integrant; PostgreSQL; Redis/Valkey; RPC; HTTP; storage; mail; audit/logging; workers.
+
+## Focused memories
+
+- RPC, DB helpers, workers, cron: `mem:backend/rpc-db-worker-subtleties`
+- HTTP sessions, config, storage, media, file data persistence: `mem:backend/http-storage-filedata-subtleties`
+- Auth flows, permission model, teams, projects, invitations, comments, webhooks, audit: `mem:backend/auth-permissions-product-domains`
+- Services, task-queue/Pub-Sub topology constraints -> `mem:prod-infra/core`.
+
+## Stable namespace map
+
+- `app.rpc.commands.*`: RPC command implementations exposed under `/api/rpc/command/<cmd-name>`.
+- `app.rpc.permissions`: permission predicate/check helper factories.
+- `app.http.*`: HTTP routes and middleware.
+- `app.auth.*`: provider-specific authentication helpers such as LDAP/OIDC.
+- `app.loggers.*`: audit, webhook, database, and external log integrations.
+- `app.db.*` / `app.db`: next.jdbc wrapper and SQL helpers.
+- `app.tasks.*`: background task handlers.
+- `app.worker`: task execution/cron plumbing.
+- `app.main`: Integrant system map and component wiring.
+- `app.config`: `PENPOT_*` env config and feature flags.
+- `app.srepl.*`: development REPL helpers for manual backend operations (data inspection, migration helpers, one-off admin tasks).
+- `app.nitrate`, `app.rpc.commands.nitrate`, and `app.rpc.management.nitrate`: external Nitrate subscription/organization integration, gated by the `:nitrate` feature flag and shared-key HTTP calls.
+
+## RPC conventions
+
+RPC commands are defined with `app.util.services/defmethod` and schemas. Use `get-` prefixes for read operations. Command metadata usually includes auth, docs version, params schema, and result schema. Return plain maps/vectors or raise structured exceptions from `app.common.exceptions`.
+
+Backend RPC command areas without focused memories include access tokens, binfile, demo, feedback, file snapshots, fonts, management, Nitrate, and webhooks beyond the notes in `mem:backend/auth-permissions-product-domains`; inspect nearby command tests and command metadata before changing them.
+
+## DB conventions
+
+`app.db` helpers accept cfg, pool, or conn in most places and convert kebab-case to snake_case:
+- `db/get`, `db/get*`, `db/query`, `db/insert!`, `db/update!`, `db/delete!`.
+- Use `db/run!` for multiple operations on one connection.
+- Use `db/tx-run!` for transactions.
+
+Database migrations live in `backend/src/app/migrations/`; pure SQL migrations are under `backend/src/app/migrations/sql/`. SQL filenames conventionally start with a sequence and verb/table description, e.g. `0026-mod-profile-table-add-is-active-field`. Applied migrations are tracked in the `migrations` table.
+
+For interactive PostgreSQL access with correct dev defaults, use `tools/psql`; to dump
+the current DDL schema, use `tools/db-schema` (see `mem:tools/psql`).
+
+For deeper details on transaction semantics, advisory locks, Transit vs JSON helpers, and dev/test DB URLs: `mem:backend/rpc-db-worker-subtleties`.
+
+## Background tasks
+
+A task handler is an Integrant component with `ig/assert-key`, `ig/expand-key`, and `ig/init-key`, returning the function run by the worker. New tasks also need wiring in `app.main`: handler config, worker registry entry, and cron entry if scheduled.
+
+For worker dispatch, cron, retry semantics, deduplication, and queue internals: `mem:backend/rpc-db-worker-subtleties`.
+
+## REPL
+
+In devenv, backend nREPL is exposed on port 6064.
+
+### Non-interactive eval (preferred for agents)
+
+`./tools/nrepl-eval.mjs` connects to an already-running nREPL server and evaluates code. Session state (defs, `in-ns`) persists across invocations via a stored session ID in `/tmp/penpot-nrepl-session-<host>-<port>`.
+
+```bash
+./tools/nrepl-eval.mjs '(+ 1 2)'                            # single expression
+./tools/nrepl-eval.mjs "(require '[my.ns :as ns] :reload)"  # reload after edits
+./tools/nrepl-eval.mjs -e                                   # inspect last exception (*e)
+./tools/nrepl-eval.mjs --reset-session '(def x 0)'          # discard session, start fresh
+./tools/nrepl-eval.mjs <<'EOF'                              # multi-expression heredoc
+(def x 10)
+(+ x 20)
+EOF
+```
+
+Default port is 6064. Use `-p <PORT>` for a different port. Use `-t <MS>` to override the 120s timeout. Do not start the nREPL server — assume it is already running.
+
+### Interactive REPL
+
+`backend/scripts/nrepl` starts a REPLy client connected to the running nREPL.
+
+For an in-process backend REPL (where you control the JVM lifecycle), stop the running backend first so port 9090 is free, then run `backend/scripts/repl`. Useful top-level helpers include `(start)`, `(stop)`, `(restart)`, `(run-tests)`, and `(repl/refresh-all)`. Many `app.srepl.main` helpers accept the global `system` var, e.g. manual email or maintenance operations.
+
+## Fixtures
+
+Fixtures can populate local data for manual testing/perf work. From the backend REPL, run `(app.cli.fixtures/run {:preset :small})`; fixture users conventionally look like `profileN@example.com` with password `123123`. Standalone fixture aliases may exist, but check current `backend/deps.edn` before relying on old command names.
+
+## Performance
+
+* **Type Hinting:** Use explicit JVM type hints (e.g. `^String`, `^long`) in performance-critical paths to avoid reflection overhead.
+* **Batch inserts:** Use `db/insert-many!` for bulk row inserts — generates a single SQL with multiple parameter tuples. Avoid on very large datasets (SQL length / parameter count limits).
+* **Server-side cursors:** Use `db/plan` (fetch-size 1000, forward-only, read-only) or `db/cursor` for large result sets. Never fetch large collections into memory at once.
+* **Transaction discipline:** Use `tx-run!` for writes (opens a transaction), `run!` for reads (single connection, no transaction). Set `:read-only` on `tx-run!` when applicable to let PostgreSQL optimize.
+
+## Lint and Format
+
+IMPORTANT: all CLI commands must be executed from the `backend/` subdirectory.
+
+* **Linting:** `pnpm run lint` from the repository root.
+* **Formatting:** `pnpm run check-fmt`. Use `pnpm run fmt` to fix. Avoid unrelated whitespace diffs.
+
+**Before linting:** if delimiter errors are suspected (after LLM edits), run
+`tools/paren-repair.bb` on the affected files first. Delimiter errors produce
+misleading linter/compiler output. See `mem:tools/paren-repair`.
+
+## Testing
+
+IMPORTANT: all CLI commands must be executed from the `backend/` subdirectory. JVM tests are invoked directly via `clojure -M:dev:test` — there is no pnpm wrapper. If you need to filter output, tee to a temp file first: `clojure -M:dev:test 2>&1 | tee /tmp/penpot-test-output.txt`. See `mem:testing` for execution discipline.
+
+* **Coverage:** If code is added or modified in `src/`, corresponding tests in `test/backend_tests/` must be added or updated.
+* **Isolated run:** `clojure -M:dev:test --focus backend-tests.my-ns-test` for a specific test namespace.
+* **Regression run:** `clojure -M:dev:test` to ensure no regressions in related functional areas.
+* **Principles:** Cross-cutting testing principles, anti-patterns, and verification checklist: `mem:testing`.

+# Backend HTTP, Storage, Media, and File Data Subtleties
+
+## Config and HTTP/session middleware
+
+- `app.config/config` and `flags` are dynamic `defonce` vars populated from `PENPOT_*` env vars through the shared schema string transformer. Tests and tooling can bind them.
+- `parse-flags` automatically adds `:disable-secure-session-cookies` when `public-uri` is plain HTTP and not localhost. This changes cookie defaults without an explicit env flag.
+- The backend sets Clojure `*assert*` globally from the `:backend-asserts` feature flag. Assertion-dependent checks can therefore differ by runtime flags.
+- Request body parsing is mostly POST-oriented and supports Transit JSON plus plain JSON. Plain JSON request keys are kebab-decoded before being merged into `:params`.
+- Response formatting negotiates with `Accept` or `_fmt=json`. Transit is the default for collection/boolean bodies; JSON encoding has special pointer-map handling.
+- Auth prefers the session cookie token before the `Authorization` header. Headers may be `Token` or `Bearer`; JWTs with `kid=1` and `ver=1` are decoded as v1 session tokens, otherwise they are treated as legacy tokens.
+- Shared-key auth requires `x-shared-key` as `<key-id> <key>` and stores the lowercased key id on the request. If no shared keys are configured it always rejects.
+- Session management uses DB storage unless the DB pool is read-only, then falls back to the in-memory manager. DB sessions support both legacy string ids and v2 UUID session ids.
+- Session cookies are renewed when using a legacy string id or when `modified-at` is older than the renewal interval. SameSite is `none` for CORS, otherwise strict/lax based on config.
+
+## Storage and media
+
+- Storage has a fixed valid bucket set. Backends are `:fs` and `:s3`; default backend comes from deprecated `assets-storage-backend` only when present, otherwise `objects-storage-backend`, defaulting to `:fs`.
+- `put-object!` creates the DB `storage_object` row before writing backend content. Backend writes happen only for newly created rows, so deduplication can skip object writes.
+- Deduplication only applies when requested, when the content can provide a hash, and when bucket metadata is present. Reads exclude soft-deleted storage rows.
+- `sto/resolve` can reuse the current DB connection via `::db/reuse-conn true`; preserve this in transaction-sensitive code.
+- SVG validation strips DOCTYPE and uses secure SAX parsing. Basic SVG info falls back to 100x100 dimensions when width/height/viewBox are missing.
+- Raster metadata is shell-derived with ImageMagick `identify`, verifies detected MIME against the supplied MIME, and swaps dimensions for EXIF orientations 6/8.
+- Remote image download requires 2xx status, `content-length`, a known MIME, and size under the configured maximum before writing the temp file; mismatched byte count is an internal error.
+- Font processing shells out to FontForge and WOFF conversion tools and can derive TTF/OTF/WOFF variants from uploaded fonts.
+
+## File data persistence
+
+- File data backends are `legacy-db`, `db`, and `storage`. The storage backend keeps encoded file data in storage bucket `file-data`; the DB row stores metadata with `storage-ref-id` and nil data.
+- `fdata/upsert!` touches any storage object referenced by incoming metadata before storing the new row/blob.
+- Pointer-map fragments are persisted separately as type `fragment`, and only modified pointer maps are written.
+- `fdata/realize` combines pointer realization and object-map realization. Use it before operations that need complete in-memory file data instead of pointer placeholders.

+# Backend RPC/DB/Worker Subtleties
+
+## RPC exposure and wrappers
+
+- RPC commands are discovered from vars created by `app.util.services/defmethod`; adding a command namespace is not enough unless `backend/src/app/rpc.clj` includes it in `resolve-methods`.
+- `GET`/`HEAD` RPC calls are only allowed for method names starting with `get-`. Other methods are method-not-allowed even if they are read-only internally.
+- RPC auth defaults to enabled. Public endpoints must set `::auth false` metadata explicitly.
+- The wrapper stack does auth before params validation, then auditing/rate/concurrency/metrics/retry/condition handling, with DB transaction handling inside that stack. `::db/transaction` metadata controls transaction wrapping.
+- Params with `::sm/params` are decoded/conformed through the JSON transformer and successful IObj results get `:encode/json` metadata. Legacy spec conforming only applies when no Malli params schema exists.
+- Nil RPC bodies become HTTP 204 unless explicit status metadata is present. Stream bodies default to `application/octet-stream` when no content type is set.
+
+## DB helpers
+
+- Most `app.db` helpers accept a pool, connection, or map containing `::db/pool` / `::db/conn`; preserve that convention in shared code.
+- `db/tx-run!` uses `next.jdbc.transaction/*nested-tx* :ignore`: nested transaction calls reuse the outer transaction, not a savepoint. Use explicit savepoints when nested rollback semantics matter.
+- `db/run!` opens/reuses one connection but does not create a transaction.
+- `db/tjson` is Transit JSON for jsonb storage; `db/json` is plain JSON. Worker task props use Transit and are decoded with `decode-transit-pgobject`.
+- Advisory transaction locks accept UUIDs or ints. UUID locks are hashed using a zero-UUID seeded siphash.
+
+## Workers and cron
+
+- Task queues are tenant-prefixed. Submit dedupe only removes not-yet-due `new` tasks with the same name/queue/label; it does not dedupe due, scheduled, retry, running, or completed work.
+- The dispatcher selects `new`/`retry` tasks with `FOR UPDATE SKIP LOCKED`, marks them `scheduled`, and publishes Redis payload `[id scheduled-at]`. The runner skips Redis messages whose scheduled timestamp no longer matches DB state.
+- Lost `scheduled` tasks are rescheduled after about 5 minutes; `running` tasks older than about 24 hours are marked failed as orphans.
+- A task handler that is missing or returns an invalid result currently defaults to completed after warning. Throwing with `ex-data :type ::retry` controls retry behavior; `:strategy ::noop` retries without incrementing retry count.
+- Cron jobs lock their `scheduled_task` row with `FOR UPDATE SKIP LOCKED`, disable statement/idle-in-transaction timeouts locally, and reschedule themselves in `finally` unless interrupted. Worker, dispatcher, and cron components do not start when the DB pool is read-only.

+# File Mutations: Changes and Undo Architecture
+
+Penpot mutates file data through change records. A change set is both the persistence payload and the basis for undo/redo, so UI actions, tests, backend file updates, and library/file tooling should drive the production change pipeline instead of ad hoc object-map mutation.
+
+## Change shape
+
+Each change is a map such as `{:type ... :id ... :page-id ...}`. Common families:
+
+- `:add-obj`, `:mod-obj`, `:del-obj`: shape lifecycle. `:mod-obj` contains `:operations`, commonly `{:type :set :attr ... :val ... :ignore-geometry ... :ignore-touched ...}` or `{:type :set-touched ...}`.
+- `:add-component`, `:mod-component`, `:del-component`: component/library metadata.
+- `:add-children`, `:remove-children`, `:reg-objects`: tree and object-map edits.
+- `:set-option`, `:add-page`, `:mov-page`, and related file/page metadata changes.
+
+Each transaction carries `:redo-changes` and inverse `:undo-changes`. The undo stack stores transactions and can move its index backward/forward.
+
+## changes-builder API
+
+`common/src/app/common/files/changes_builder.cljc` (usually alias `pcb`) is the fluent builder. Start from `(pcb/empty-changes <it> <page-id>)` or `(pcb/empty-changes nil <page-id>)` for tests.
+
+High-value builder operations:
+- `pcb/with-page-id`, `pcb/with-objects`, `pcb/with-library-data`: set context for following operations.
+- `pcb/update-shapes ids update-fn`: emits `:mod-obj` with diff-derived `:set` ops. Options include `{:with-objects? true}`, `{:ignore-touched true}`, and `{:attrs #{...}}`.
+- `pcb/add-objects`, `pcb/change-parent`, `pcb/remove-objects`, `pcb/resize-parents`: shape/tree edits.
+- `pcb/add-component`, `pcb/update-component`, `pcb/mod-component`: component/library edits.
+- `pcb/set-translation? true`: marks the whole change set as translation-only, which lets component sync skip expensive work.
+
+## Applying changes in tests
+
+`thf/apply-changes` in `app.common.test-helpers.files` is the test analog of the production applier. It validates by default; pass `:validate? false` only for intentionally-invalid intermediate states.
+
+The applier uses the same `process-operation` multimethod as production (`common/src/app/common/files/changes.cljc`), so tests that use it exercise production behavior.

For the exact `set-shape-attr` / second-pass behavior during change application, read `mem:common/file-change-validation-migration-subtleties`.

+# Component and Variant Data Model
+
+## Shape roles relative to components
+
+A shape can occupy multiple roles at once:
+
+1. Master/main instance: defines a component and has `:main-instance true` plus `:component-id`.
+2. Copy/non-main instance: produced by instantiating a component and carries `:shape-ref` pointing at the master shape. `(ctk/in-component-copy? shape)` is essentially `(some? (:shape-ref shape))`.
+3. Component root: topmost shape of an instance, marked `:component-root true` and carrying surface attrs such as `:component-id` and `:component-file`.
+
+Variant masters are main instances and component roots. Their descendants may themselves be component copies, so master/copy logic must handle nested instances rather than assuming those roles are exclusive.
+
+## :shape-ref chains
+
+`:shape-ref` walks up the inheritance hierarchy and can cross files for remote libraries. `find-ref-shape` and `get-ref-chain-until-target-ref` in `app.common.types.file` follow this chain.
+
+`find-shape-ref-child-of` in `app.common.logic.variants` walks the chain looking for the first ref-shape whose ancestors include a specific parent. Variant switch uses this to locate the equivalent master child in the target variant.
+
+## :touched flags
+
+`:touched` is a set of override-group keywords such as `:geometry-group`, `:fill-group`, and `:text-content-group`. It means a copy diverged from its master for attrs in that sync group.
+
+`sync-attrs` in `app.common.types.component` maps attrs to groups. `set-touched-group` is the legitimate setter; the central `set-shape-attr` path calls it only for copies and only when ignore flags allow it.
+
+Masters are not normally touched through `set-shape-attr`, but touched flags can appear on master shapes through cloning/duplication paths. `add-touched-from-ref-chain` in `app.common.logic.variants` unions touched flags from ancestors into the copy being processed, so upstream/master touched state can affect downstream switch behavior.
+
+## Cloning paths
+
+`make-component-instance` in `app.common.types.container` produces a clean component copy through `update-new-shape`, dissociating attrs such as `:touched`, `:variant-id`, and `:variant-name` on cloned shapes.
+
+`duplicate-component` in `app.common.logic.libraries` creates a new component master by cloning existing component shapes, setting component metadata, and applying a position delta. It does not have the same clean-copy semantics as `make-component-instance`, so inherited attrs on the source can matter.
+
+When a bug depends on touched state, identify which cloning path produced the shape before changing sync logic.
+
+## Variant containers
+
+A variant container is a frame with `:is-variant-container true`. Its children are variant masters with `:variant-id` pointing at the container and `:variant-name` naming the variant value. Component records in the library carry `:variant-properties`.
+
+Predicates are broad: `ctk/is-variant?` checks `:variant-id` and applies to both variant master shapes and component rows; `ctk/is-variant-container?` checks the container shape flag.
+
+Moving/dropping a shape into a variant container through the move-to-frame path can auto-convert it into a variant via `generate-make-shapes-variant`, which may duplicate the underlying component. Treat drag/drop into variant containers as a component/variant operation, not a plain reparent.

+# Component Swap and Variant Switch Pipeline
+
+## Entry points
+
+Frontend entry points under `frontend/src/app/main/data/workspace/`:
+- `variants.cljs`: `variants-switch` and `variant-switch` events feed property-toggle UI and Plugin API `switchVariant` behavior into `dwl/component-swap`.
+- `libraries.cljs`: `component-swap` is the single-swap workhorse; `component-multi-swap` batches swaps and calls `component-swap` with `keep-touched? = false`.
+
+`keep-touched? = true` is the discriminator for preserving user overrides during variant switch. Batch/multi-swap paths intentionally bypass that logic.
+
+## Common-side pipeline
+
+For a single swap with `keep-touched? = true`:
+
+1. `cll/generate-component-swap` in `common/src/app/common/logic/libraries.cljc` builds the base changes: remove old shape and instantiate the target component in its place through `generate-new-shape-for-swap`, `generate-instantiate-component`, and `make-component-instance`.
+2. `clv/generate-keep-touched` in `common/src/app/common/logic/variants.cljc` walks pre-swap children, augments each with chain-derived touched flags through `add-touched-from-ref-chain`, finds the equivalent target shape through `find-shape-ref-child-of`, then calls `update-attrs-on-switch`.
+3. `update-attrs-on-switch` in `app.common.logic.libraries` decides which touched attrs from the previous shape should be copied onto the freshly instantiated target shape.
+
+## update-attrs-on-switch hazards
+
+The routine compares `current-shape` (fresh target copy), `previous-shape` (pre-swap shape with chain-derived touched), and `origin-ref-shape` (source variant master's equivalent shape). It loops over sync attrs except `swap-keep-attrs` and copies only attrs that pass several guards:
+
+- skip equal previous/current values;
+- skip equal composite geometry for selected attrs;
+- require the corresponding touched group;
+- for most attrs, require source and target masters to agree;
+- for fixed-size selrect/points/width/height, use dedicated fixed-layout geometry handling;
+- text and path shapes have specialized value conversion paths.
+
+The generic fallback branch copies from `previous-shape`. It represents the intended "carry user override through switch" behavior, but bugs usually appear when guards fail to reject incompatible geometry or master differences before reaching that branch.
+
+## Known sharp edges
+
+- Composite `:selrect` and `:points` bypass the simple different-master skip; width/height checks catch some but not all positional differences.
+- `previous-shape` may be repositioned by destination-root minus origin-root before copying. For normal variant switch this is often zero, but do not assume it for all swap entry points.
+- Touched flags can be inherited through ref chains, so a shape that looks untouched locally may still behave as touched after `add-touched-from-ref-chain`.
+
+## Test harness
+
+`common/src/app/common/test_helpers/compositions.cljc` has `swap-component-in-shape`, which drives `generate-component-swap` plus `generate-keep-touched` with the production `keep-touched?` flag. Use it for focused common tests of variant-switch behavior.
+
+`common/test/common_tests/logic/variants_switch_test.cljc` is the canonical reference suite for swap+touched scenarios. Read nearby tests before adding another case.

+- `app.common.data` and `app.common.data.macros`: generic data helpers and performance macros that do not depend on Penpot domain entities.
+- `app.common.types.*`: shared shape/file/page/component/token data types, schemas, predicates, and entity-local operations. `app.common.types.nitrate-permissions` contains shared fail-closed Nitrate organization/team permission rules.

+# Common Data Model Change Checklist
+
+## Attribute conventions
+
+- Prefer optional page/shape attrs with default behavior when absent. Reverting to default should usually remove the attr instead of storing nil.
+- Do not treat nil as a distinct persisted state from absence. Import/export and cleanup paths may filter nil attrs away.
+- Avoid Clojure-special naming in exported object attrs, especially boolean names ending in `?`; exported/imported data must survive JSON/SVG/Transit and external tooling.
+- Any new shape attr that participates in component sync must be listed in `app.common.types.component/sync-attrs` with the correct touched group. Attrs absent from `sync-attrs` are ignored by component synchronization.
+
+## Cross-module update checklist
+
+When changing the file data model, check the relevant paths:
+- Schema/type definitions under `common/src/app/common/types*` and helpers under `common/src/app/common/files*` / `logic*`.
+- File migrations in `common/src/app/common/files/migrations.cljc` when old files cannot safely use absence/default behavior.
+- Frontend edit forms under `frontend/src/app/main/ui/workspace/sidebar/options/`; multi-selection behavior is usually in `multiple.cljs` and must handle `:multiple` values.
+- SVG/file render and export metadata under `frontend/src/app/main/ui/shapes/*`, especially `export.cljs` when an attr is not a native SVG property.
+- SVG import/parser paths under `frontend/src/app/worker/import/parser.cljs`; attrs not exported and imported will be lost on reimport.
+- Viewer inspect and code generation under `frontend/src/app/main/ui/viewer/inspect/*` and `frontend/src/app/util/code_gen.cljs` / markup/style helpers when handoff output should expose the attr.
+- Exporter/library consumers when the change affects file construction, rendering, or packaged `.penpot` archives.
+
+## Migrations
+
+Existing files should keep working unchanged when possible. If absence cannot preserve old behavior, add a migration and preserve append/order semantics described in `mem:common/file-change-validation-migration-subtleties`.
+
+Model changes can also require file feature flags or migration metadata updates; check nearby migrations and `common/src/app/common/features.cljc` before inventing a new pattern.

+# Decimals and Coordinates in Penpot
+
+Penpot stores all geometry as JS numbers (doubles in CLJS, doubles in
+CLJ for the JVM-side common code). Several Penpot-specific facts
+about how this plays out are not obvious from reading the code.
+
+## Sub-pixel drift is routine
+
+Coordinate values that "should" be integers are routinely off by ~1e-5
+in production data. A `:width` of 107 will frequently appear as
+`107.00001275539398` after the value has passed through:
+
+- the modifier propagation pipeline (`apply-wasm-modifiers` and the
+  Rust WASM transform engine)
+- any rotation/scale composition
+- repeated translations
+
+This drift is invisible in the UI (the renderer rounds at draw time)
+but defeats exact equality comparisons in business logic. It does NOT
+appear in JVM-only test setups because the WASM pipeline isn't
+involved — tests that build shapes via `setup-shape` and `add-sample-shape`
+get clean integer values. Bugs that depend on drift will pass tests
+but fire in production unless tests explicitly inject drift.
+
+## Use the close? helpers, not `=`
+
+For comparing coordinate-like floats, the established convention is:
+
+- `app.common.math/close?` — scalar tolerance comparison.
+  Default precision 0.001 (sub-pixel; tight enough to keep distinct
+  shapes distinct, loose enough to absorb arithmetic noise).
+  Two-arity uses default precision; three-arity takes a custom one.
+- `app.common.geom.point/close?` — element-wise close on `gpt/Point`
+  records. Compares :x and :y via `mth/close?`.
+- `app.common.geom.matrix/close?` — close on transform matrices.
+- `app.common.geom.shapes/close-attrs?` — used inside `set-shape-attr`
+  to decide whether a re-assigned `:width`/`:height` should be treated
+  as a no-op (suppresses spurious touched marking from drift).
+
+Treat `=` on `:x`, `:y`, `:width`, `:height`, `:selrect`, or `:points`
+fields as a code smell when the inputs may have flowed through any
+transform. The `set-shape-attr`-style precedent (already using
+`close-attrs?`) is the right model.
+
+## The redundancy multiplies failure modes
+
+A shape's position lives in `:x/:y`, `:selrect`, AND `:points` (see
+`mem:common/geometry-invariants` memory). Each is a separate set of float
+values. After any operation that touches geometry, all three should
+agree, but each is computed by a different path and accumulates
+its own drift. Comparing `:selrect.width` from shape A to
+`:selrect.width` from shape B is comparing two values that
+"semantically" should be equal but were computed via different
+operation chains — exact equality will often be false.

+# Common File Change, Validation, and Migration Subtleties
+
+## Change application
+
+- `process-changes` validates the whole change vector once by default, reduces changes, then performs a second pass for collected touched changes. Callers that already validated can pass `verify? false`.
+- `process-operation :set` delegates to `ctn/set-shape-attr`; `:assign` first decodes attrs with the shape-attrs JSON transformer and then emits per-attr set operations.
+- `set-shape-attr` treats `:position-data` as derived and never touched. Geometry/content-path changes use approximate equality; geometry differences under about 1px can be ignored for touched purposes.
+- Width/height are excluded from the `is-geometry?` branch in `set-shape-attr`; do not assume all geometry-group attrs follow identical ignore-geometry behavior.
+- `process-touched-change` marks the owning component modified when a touched shape belongs to a main instance; component-data changes can come from shape ops through this second pass.
+
+## Shape tree edits
+
+- `shape-tree/add-shape` falls back invalid/missing parent or frame ids to root (`uuid/zero`), ensures parent `:shapes` is a vector, avoids duplicate child ids, and clears `:remote-synced` on copy parents unless `ignore-touched` is true.
+- `shape-tree/delete-shape` removes the shape and all descendants from the objects map and removes the id from its parent. This is different from render-wasm deletion, which may keep deleted children for undo/redo internals.
+- Page object maps can carry metadata indexes such as cached frame lists. `start-page-index` / `update-page-index` rebuild those metadata indexes; `frontend` commit application calls `ctst/update-object-indices` after page changes.
+
+## Validation and repair
+
+- Full referential/semantic validation currently runs only when file features contain `"components/v2"`.
+- Validation starts at root plus orphan shapes, then validates component records. `validate-file!` raises `:validation :referential-integrity` with collected details.
+- `repair-file` does not mutate data directly; it reduces validation errors into redo changes using `changes-builder`. Callers must apply or persist those changes.
+
+## Migrations
+
+- Prefer optional attrs/default behavior so old files continue working without migration. If absence cannot preserve old behavior, add a migration.
+- Migrations are an ordered set mixing legacy version-derived ids and newer named ids. Keep append order stable; `migrate` applies the set difference between available migrations and file migrations.
+- `migrate-file` synthesizes legacy migration ids from old numeric versions when `:migrations` is absent, migrates legacy features, and records feature flags created through `cfeat/*new*`.
+- When a file had no previous `:migrations`, `migrate-file` marks all migrations as migrated in metadata so callers persist the complete migration set, not only transformations that changed data.

+# Geometry Invariants in Penpot Shapes
+
+Core invariant: shape position is stored redundantly, and all geometry fields must stay coherent.
+
+## Redundant fields
+
+For a shape at `(x, y)` with width `w` and height `h`:
+
+- `:x`, `:y`, `:width`, `:height`: top-left and dimensions.
+- `:selrect`: `{:x :y :width :height :x1 :y1 :x2 :y2}`, where `x2 = x + w` and `y2 = y + h`.
+- `:points`: four corners for an axis-aligned rect, clockwise from top-left.
+- `:transform` and `:transform-inverse`: identity for axis-aligned shapes; populated for transformed shapes.
+
+After a geometric mutation, equivalent fields such as `:y`, `(:y :selrect)`, and the first point's `:y` should agree. The renderer and hit-testing read `:selrect` / `:points`, so a shape can render or select incorrectly even when `:x` / `:y` look right.
+
+## Helpers that preserve the invariant
+
+- `gsh/move`: translates by delta and updates geometry consistently.
+- `gsh/absolute-move`: moves to an absolute position by computing a delta from the current selrect.
+- `gsh/transform-shape`: applies a full transform.
+- `cts/setup-shape`: initializes geometry for new shapes; variant test helpers such as `thv/add-variant-with-child` use it.
+
+## Edits that break the invariant
+
+- `(assoc shape :x ...)` or `(assoc shape :y ...)`: updates only one field and leaves `:selrect` / `:points` stale.
+- `ths/update-shape file label :y val`: goes through `set-shape-attr`, but does not repair all position fields for `:y` alone.
+- Direct `update-in` edits to `:selrect`, `:points`, or dimensions.
+
+## Test setup warning
+
+When positioning test shapes, use `gsh/absolute-move`, `gsh/move`, or production change helpers. Do not set only `:x` / `:y`.
+
+```clojure
+(cls/generate-update-shapes
+  (pcb/empty-changes nil page-id)
+  #{(:id child)}
+  #(gsh/absolute-move % (gpt/point (:x %) 101))
+  (:objects page)
+  {})
+```
+
+Using `(ths/update-shape file label :y 101)` leaves `:selrect.y` stale. Downstream code that reads `:selrect` can then fail in ways that look like product bugs but are only invalid test setup.
+
+## :touched and geometry mutation
+
+When a copy shape changes geometry through the proper pipeline (`set-shape-attr` via `process-operation :set`), `:touched` gains `:geometry-group` unless ignored. Tests can either drive the production update with `cls/generate-update-shapes`, or inject `(assoc shape :touched #{:geometry-group})` when only touched state matters.
+
+If a test needs both a new position and touched state, move the shape first with geometry-preserving helpers, then inject or assert touched state.

+# Common Layout and Grid Subtleties

+## Layout metadata
+
+- Layout container data and child layout-item data are removed by different helpers. Do not assume clearing a layout frame also clears all child layout metadata.
+- Layout data can affect both container attrs and immediate child attrs; validate behavior for both sides when changing cleanup or propagation.

+- Grid `assign-cells` ensures at least one column and row, skips absolute-position children, creates non-tracked rows/cols when children exceed tracked cells, and asserts that assigned cells do not overlap.
+- Grid deassignment removes cells for shapes that are no longer direct children or have become absolute-positioned.

+# Common Testing and Verification
+
+`common/` is CLJC shared code. Tests should cover the relevant runtime(s): JVM for backend/common logic and JS for frontend/exporter behavior. For geometry, component, and file-model changes, JVM tests are common and fast, but JS/browser behavior can differ when WASM modifier math or CLJS-specific state is involved.
+
+## Unit tests
+
+READ `mem:testing` FIRST — it defines the execution discipline (no piping, tee to file, preferred commands) that applies to all CLJS/JS and JVM test runs.
+
+Common tests live under `common/test/common_tests/` and use `clojure.test`.
+They are CLJC and run on both JVM and JS.
+
+From `common/`:
+- Full JVM test run: `clojure -M:dev:test`
+- Full JS test run (always builds, suppressed output): `pnpm run test:quiet`
+- Full JS test run (always builds, build output visible): `pnpm run test`
+- Focus a JVM test namespace: `clojure -M:dev:test --focus common-tests.logic.variants-switch-test`
+- Focus a JVM test var: `clojure -M:dev:test --focus common-tests.logic.variants-switch-test/test-basic-switch`
+- Focus a JS test namespace: `pnpm run test:quiet -- --focus common-tests.logic.comp-sync-test`
+- Focus a JS test var: `pnpm run test:quiet -- --focus common-tests.logic.comp-sync-test/test-sync-when-changing-attribute`
+- Quiet logging during a JS run: append `--log-level warn` (or `trace|debug|info|warn|error`)
+- Build JS test target only (no run): `pnpm run build:test`
+- After `build:test` has been run, run the compiled runner directly: `node target/tests/test.js [--focus ...] [--log-level ...]`.
+
+New common JS test namespaces must be required/listed in `common_tests/runner.cljc`;
+new vars in existing namespaces need no runner change. Multiple JVM `--focus` flags
+compose as a union.
+
+## Test helpers
+
+Helpers live under `common/src/app/common/test_helpers/` and are usually aliased with short `th*` prefixes. Test namespaces using label->uuid helpers should start with `(t/use-fixtures :each thi/test-fixture)` so labels reset between tests.
+
+Useful builders:
+- `thf/sample-file` creates a base file.
+- `tho/add-simple-component` creates a simple component.
+- `thc/instantiate-component` instantiates a component copy.
+- `thv/add-variant-with-child` creates a variant container with two child variants.
+- `thv/add-variant-with-copy` creates variants whose children are component instances.
+
+`add-variant-with-copy` does not accept position params for children; use `gsh/absolute-move` after creation if positions matter.
+
+## Driving production paths
+
+For shape mutations, prefer production-path helpers such as `cls/generate-update-shapes` plus `thf/apply-changes`. For component swaps with keep-touched behavior, use `tho/swap-component-in-shape` with `{:keep-touched? true}`.
+
+`thf/apply-changes` validates by default and usually gives the most useful invariant failure. Pass `:validate? false` only for intentionally malformed intermediate state.
+
+## Geometry setup caution
+
+For geometry-sensitive tests, read `mem:common/geometry-invariants` before positioning shapes. Use geometry-preserving helpers or production change helpers rather than direct single-field edits.
+
+## Debugging
+
+Use `mem:common/component-debugging-recipes` for shape-tree dumps, undo/change inspection, and temporary live instrumentation recipes.

+# Common Tokens and Schema Subtleties
+
+## Tokens
+
+- `TokensLib` always ensures an internal hidden theme exists and defaults active themes to that hidden theme path. That hidden theme represents the UI state where active sets are controlled without modifying a user-created theme.
+- `get-tokens-in-active-sets` merges tokens from sets selected by active themes in set order, so later active sets with the same token name override earlier ones.
+- Activating a real theme in `common.logic.tokens` removes the hidden theme from the active-theme set unless it is the only active theme. Toggling active sets directly copies current active sets into the hidden theme.
+- DTCG import/export deliberately hides the internal hidden theme: exports omit it from `$themes` and activeThemes, while `activeSets` records the hidden/current active sets.
+- Single-set DTCG/legacy imports throw if no supported tokens are found. Multi-set import normalizes set names, keeps `tokenSetOrder`, rejects conflicting token path names, discards unsupported token types, and validates theme sets against existing sets.
+- Token values stored on shapes are token names in `:applied-tokens`, not token ids. Renames and group renames must update those name paths.
+- Token serialization has both Transit handlers for frontend/backend transport and Fressian handlers for internal file-data storage, with migrations for older token-lib internal versions.
+
+## Schema
+
+- `app.common.schema/json-transformer` has custom map-of key decoding/encoding, so map keys can be transformed based on the key schema instead of only the value schema.
+- `check-fn` throws `ex-info` with default `:type :assertion`, `:code :data-validation`, and `::explain`. Prefer reusable `check-fn`/lazy validators in hot or repeated paths; `sm/check` creates a checker every call.

+# Devenv startup and configuration
+
+Compose-based dev environment under `docker/devenv/`, driven by `manage.sh`. Parallel instances share infra + Postgres + MinIO; each instance has its own `main` container, Valkey, source checkout, tmux session.
+
+## Compose project layout
+
+- `penpotdev-infra`: shared `postgres`, `minio`, `minio-setup`, `mailer`, `ldap`. File: `docker-compose.infra.yml`.
+- `penpotdev-wsN` (N=0,1,…): per-instance `main` + `redis` (Valkey). File: `docker-compose.main.yml`. ws0 (a.k.a. `main`) binds `$PWD`; ws1+ bind clones at `${PENPOT_WORKSPACES_DIR}/wsN/` (default `~/.penpot/penpot_workspaces/`), maintained by the developer.
+- All projects join external network `penpot_shared`. Created idempotently by `ensure-devenv-network`, never removed by lifecycle commands.
+
+## Source-of-truth files
+
+- `docker/devenv/defaults.env`: ws0 baseline — container/volume names, runtime env, published host ports, tmux defaults. `manage.sh` aborts if unreadable.
+- For ws1+, `instance-env-overrides` computes the per-instance overrides (container/volume names, host ports offset `10000·N`, `PENPOT_PUBLIC_URI`, `PENPOT_REDIS_URI`, `PENPOT_BACKEND_WORKER=false`) and `instance-compose` injects them as env vars at compose time — never written to disk, recomputed each call so they can't drift. ws0 uses `defaults.env` as-is.
+- `backend/scripts/_env`: backend-internal only — secret keys, `PENPOT_FLAGS` (with `enable-backend-worker` gated on `PENPOT_BACKEND_WORKER`), `JAVA_OPTS`, `setup_minio()`. Never duplicates `defaults.env`.
+- Compose files use pure `${VAR}` substitution; missing var = compose fails.
+
+## Invariants
+
+- `infra-compose` / `instance-compose` wrap `docker compose` with `env -i`, then re-inject what compose needs. Stripping is required because `defaults.env` is sourced into manage.sh's shell at startup (stale values would leak); the ws1+ overrides are deliberately re-injected as shell env vars precisely because Compose gives shell precedence over `--env-file`, so they override the `defaults.env` baseline.
+- Volume names pinned via `name:` (PENPOT_*_VOLUME), decoupled from the compose project name. ws1+ inject distinct per-instance volume names; ws0 keeps the historical `penpotdev_*` physical names so project renames never require data migration.
+- Network aliases (`- main`, `- redis`) are not declared in main.yml. Compose's auto-service-alias still registers `redis` on the shared network, so DNS for `redis` is non-deterministic with multiple instances. Backend uses `PENPOT_REDIS_URI=redis://penpot-devenv-wsN-valkey/0` (container_name) instead.
+- No cross-project `depends_on`. `manage.sh ensure-infra-up` `docker wait`s on the `minio-setup` one-shot.
+- `JAVA_OPTS` in `manage.sh` is shadowed inside the container by `_env`. The `-e JAVA_OPTS=...` flag only matters for processes that don't source `_env`.
+
+## Worker policy
+
+Backend workers run only on ws0. `_env` gates `enable-backend-worker` on `PENPOT_BACKEND_WORKER`; ws1+ inject it as false. ws0 must be running whenever any ws1+ is running, and is the last instance to stop — `run-devenv --agentic --ws N` (N≥1) auto-starts ws0 first; `stop-devenv` refuses to stop ws0 while any ws1+ is up. Workers are pure fire-and-forget: `wrk/submit!` inserts a row into the shared Postgres `task` table and returns; RPC handlers never wait on completion and workers never publish to msgbus. The reason for "ws0 only" is avoiding multi-instance worker races (cron dedup is best-effort across instances, `wrk/submit!` `dedupe` is racy across submitters); details in `mem:prod-infra/core`.
+
+## Port layout
+
+Container-internal ports fixed; host side offset `10000·N`.
+
+| ws0 | ws1 | wsN | container | role |
+|---|---|---|---|---|
+| 3449 | 13449 | 3449+10000·N | 3449 | public HTTPS (Caddy; `/mcp/ws` same-origin) |
+| 3449/udp | 13449/udp | … | 3449/udp | HTTP/3 |
+| 4401 | 14401 | … | 4401 | MCP HTTP stream |
+| 4403 | 14403 | … | 4403 | MCP REPL |
+| 14181 | 24181 | … | 14281 | Serena MCP |
+| 14182 | 24182 | … | 24282 | Serena dashboard |
+
+Everything else (frontend dev, backend API, exporter, storybook, REPLs, plugin dev, MCP inspector/WebSocket) is in-process or same-origin via Caddy/nginx. Infra publishes: mailer 1080, ldap 10389/10636 (singletons, not offset).
+
+## Tmux + MCP routing
+
+`docker/devenv/files/start-tmux.sh` is session-level idempotent. Reads `PENPOT_TMUX_ATTACH`. If the session exists it attaches or exits; otherwise creates 4 base windows (frontend watch / storybook / exporter / backend) plus `mcp` (when `enable-mcp` in `PENPOT_FLAGS`) and `serena` (when `SERENA_ENABLED=true`). `run-devenv --agentic` always sets both env vars. The legacy `run-devenv` alias doesn't, hence its 4-window-only session. To switch from a legacy session to agentic, `stop-devenv` then `run-devenv --agentic` — the conditional windows are only added at session create time.
+
+MCP plugin routing is same-origin: frontend uses `<public-uri>/mcp/ws`, per-instance nginx proxies to MCP port 4401 in-container. For the plugin↔MCP server wiring (how the browser plugin discovers the URL, the in-memory connection registry, why DB-mediated routing isn't needed), see `mem:mcp/core`.
+
+## Workspace orchestration (ws1+)
+
+Workspace directories are user-maintained at `${PENPOT_WORKSPACES_DIR}/wsN`. `run-devenv --agentic --ws i` syncs only when `--sync` is passed, with one exception: if the workspace directory is missing on first use, sync runs implicitly to seed it.
+
+`sync-workspace wsN`:
+1. `assert-clean-git-state` — refuses on `.git/{rebase-apply,rebase-merge,MERGE_HEAD,CHERRY_PICK_HEAD,index.lock}`. No `--sync-force` escape.
+2. `rsync -a --delete $PWD/.git/ $workspace/.git/`.
+3. `git ls-files -z --cached --others --exclude-standard` → `rsync --files-from` (Git is the authority on tracked files; rsync's gitignore filter would drop committed files under gitignored parents like `.clj-kondo/config.edn`).
+4. Initial-only copy of `frontend/resources/public/js/config.js` (gitignored, but agentic mode needs it). After the first sync the workspace's copy belongs to the developer — subsequent syncs leave it alone.
+5. `git switch -C "wsN/<current-branch>"` inside the workspace.
+
+No `--delete` on the working-tree pass: gitignored caches in the workspace survive. Workspace dir + named volumes survive `compose down`.
+
+## CLI surface
+
+- `run-devenv --agentic [--ws main|0|wsN|N] [--sync] [--serena-context CTX]`: bring one instance up. Agentic only — MCP and Serena windows are always created. Default target main. Errors out if the target is already running. `--sync` is rejected on main; on ws1+ it's optional (forced only when the workspace dir does not exist yet). Auto-starts ws0 first when the target is ws1+ and ws0 is not yet up.
+- `stop-devenv [--ws main|0|wsN|N] [--all]`: stop instances. Flags mutually exclusive. `--ws N` (N≥1) stops just that workspace. `--ws 0` or no flag stops ws0 + shared infra, refused while any ws1+ is running. `--all` stops every ws highest-first then ws0, then infra.
+- `run-devenv`: legacy alias, ws0 non-agentic attached.
+- `attach-devenv [--ws main|0|wsN|N]`: pure attach. Fails fast if instance/session missing.
+- `run-devenv-shell [--instance 0|wsN|N] [cmd...]`: bash in target instance. (`--instance` flag not yet renamed to `--ws`.)

+# Exporter Architecture and Workflow
+
+`exporter/`: CLJS/Node headless export service. Depends on `common/`; uses Playwright plus export JS/CLJS deps for SVG/PDF/assets.
+
+## Layout and commands
+
+- Source: `exporter/src/`; config: `deps.edn`, `shadow-cljs.edn`, `package.json`; runtime helpers/assets: `vendor/`, `scripts/`.
+- From `exporter/`: setup `./scripts/setup`; watch `pnpm run watch` or `pnpm run watch:app`; production build `pnpm run build`; lint `pnpm run lint`; format check/fix `pnpm run check-fmt` / `pnpm run fmt`.
+- Because exporter consumes `common/`, shared file/shape/model changes may need exporter verification even when the immediate change is not under `exporter/`.
+- Cross-cutting testing principles and anti-patterns: `mem:testing`.
+
+## HTTP and browser pool
+
+- POST body limit is about 60 MB. Exporter supports `application/transit+json`; request params merge query params and body params.
+- Map response bodies are Transit JSON and force HTTP 200; nil 200 bodies become 204.
+- Auth token comes from cookie `auth-token`, then uploads use Bearer auth plus the management shared key.
+- Each export job gets a fresh Playwright browser context. On success, the context closes and the browser returns to the pool; on error, the browser is destroyed instead of reused.
+- Borrow validates browser connection. Pool acquire timeout is about 10s; font loading timeout logs a warning and continues after about 15s.
+
+## Export batching and async behavior
+
+- `prepare-exports` groups entries by `[scale type]` and partitions groups into chunks of 50. Each partition uses file/page/share/name from its first item, so be careful if entries might cross those boundaries.
+- Single-export response is used only when multiple export is not forced and there is exactly one prepared export containing exactly one object.
+- Multi-object export can run async: when `wait` is false it returns a resource immediately and publishes progress/end/error to Redis by profile topic; when `wait` is true it waits for upload and returns the uploaded resource.
+- Frame export returns a resource immediately and publishes Redis updates; it does not follow the same `wait` option path.
+- ZIP entry names are sanitized and duplicates receive numeric suffixes.
+
+## Render details
+
+- Bitmap export differs for WASM vs non-WASM render paths: WASM forces Playwright `deviceScaleFactor` to 1 and passes scale through the render URL; non-WASM uses `deviceScaleFactor = scale`.
+- WebP is produced by taking a PNG screenshot and converting it with ImageMagick.
+- SVG export rasterizes text foreignObjects to PNG, converts through PPM/color masks/potrace, and reassembles SVG paths. It also replaces non-breaking spaces for SVG compatibility and drops empty defs/paths.
+- PDF export injects `@page` sizing through raw browser `evaluate` JavaScript; that code cannot rely on CLJS runtime helpers.
+- Temporary resources schedule local deletion, then uploads POST to `/api/management/methods/upload-tempfile` with `X-Shared-Key: exporter <management-key>` and Bearer auth.

+# ClojureScript REPL and Frontend Debugging
+
+Execute code in the live frontend via the Penpot MCP `cljs_repl` tool. For browser-console debugging, the frontend also exports a `debug` JS namespace in development builds.
+
+## Accessing app state
+
+The main store is `app.main.store/state`. It contains workspace metadata, selection, UI state, profile, route, etc. Page objects are not under a `:workspace-data` key; use derived refs.
+
+```clojure
+;; Current selection
+(mapv str (get-in @app.main.store/state [:workspace-local :selected]))
+
+;; Current page objects
+(let [objects @app.main.refs/workspace-page-objects
+      shape (get objects (parse-uuid "some-uuid-here"))]
+  (select-keys shape [:name :type :x :y :width :height :fills :strokes :rotation :opacity :frame-id :parent-id]))
+```
+
+Shape keys use kebab-case keywords. Internal `:rect` corresponds to "rectangle" in the JS Plugin API, and `:frame` corresponds to "board".
+
+Component instance shapes carry `:component-id` and `:component-file` directly; `:component-root` flags the root of an instance. Use `app.common.types.container/get-head-shape` for nearest head and `get-instance-root` for outermost root; they differ for nested instances.
+
+## Navigation recipe
+
+To programmatically open a workspace file, all three ids are required:
+
+```clojure
+(do (require '[app.main.data.common :as dcm])
+    (app.main.store/emit! (dcm/go-to-workspace
+      :team-id (parse-uuid "<team-id>")
+      :file-id (parse-uuid "<file-id>")
+      :page-id (parse-uuid "<page-id>"))))
+```
+
+Get `team-id` from `(:current-team-id @app.main.store/state)`. Get file ids from `(vals (:files @app.main.store/state))`. Get page ids by fetching file data, e.g. through `rp/cmd! :get-file` with current features.
+
+## Reload the live runtime
+
+`(.reload js/location)` (alias `app.util.dom/reload-current-window`) from `cljs_repl` reloads the browser page: clears `set!` runtime patches, re-fetches file state, and is the simplest crash recovery while the repl is live (`mem:frontend/handling-crashes`). To re-fetch only the current file's data without a full page reload, emit `(app.main.store/emit! (potok.v2.core/event :app.main.data.workspace/reload-current-file))`.
+
+## Useful lookup helpers
+
+`app.plugins.utils` contains state lookup helpers that are useful from any CLJS, despite living under `plugins/`:
+
+- `locate-shape`, `locate-objects`, `locate-file`.
+- `locate-component` resolves through the outermost instance root.
+- `locate-head-component` resolves through the nearest component head.
+- `locate-library-component` does direct file-id/component-id lookup.
+
+## Runtime patching with `set!`
+
+Some frontend vars are deliberately mutable escape hatches for runtime instrumentation or circular-dependency patching. From `cljs_repl`, use `set!` for temporary debugging of CLJS vars such as `app.main.store/on-event`, `app.main.errors/reload-file`, `app.main.errors/is-plugin-error?`, `app.main.errors/last-report`, or `app.main.errors/last-exception`. These patches affect only the live browser runtime and disappear on reload or recompilation.
+
+```clojure
+;; Log non-noisy Potok events temporarily.
+(set! app.main.store/on-event
+      (fn [event]
+        (when (potok.v2.core/event? event)
+          (.log js/console (potok.v2.core/repr-event event)))))
+```
+
+Restore mutable hooks after debugging, or reload the frontend. Use JVM `alter-var-root` only for JVM Clojure; it is not the normal way to patch live CLJS browser vars.
+
+## Browser-console debug namespace
+
+In development, the JS console exposes `debug` helpers from `frontend/src/debug.cljs`:
+
+```javascript
+debug.set_logging("namespace", "debug");
+debug.dump_state();
+debug.dump_buffer();
+debug.get_state(":workspace-local :selected");
+debug.dump_objects();
+debug.dump_object("Rect-1");
+debug.dump_selected();
+debug.dump_tree(true, true);
+```
+
+Visual workspace debug overlays can be toggled with `debug.toggle_debug("bounding-boxes")`, `"group"`, `"events"`, or `"rotation-handler"`; `debug.debug_all()` and `debug.debug_none()` toggle all visual aids.
+
+For temporary source traces, prefer existing logging (`app.common.logging` / `app.util.logging`) or short-lived `prn`, `app.common.pprint/pprint`, `js/console.log`, or `js-debugger` calls. Remove temporary source instrumentation before committing.
+
+## Runtime targeting
+
+`cljs_repl` may connect to the wrong runtime when several are attached, such as workspace plus rasterizer. Verify with `(.-title js/document)`; it should show the workspace file name, not "Penpot - Rasterizer".
+
+To list or target shadow-cljs runtimes, run from `/home/penpot/penpot/frontend`:
+
+```bash
+printf '(shadow.cljs.devtools.api/repl-runtimes :main)\n' | timeout 10 npx shadow-cljs clj-eval --stdin
+printf '(shadow.cljs.devtools.api/cljs-eval :main "<cljs-code>" {:client-id 5})\n' | timeout 10 npx shadow-cljs clj-eval --stdin
+```
+
+Use command timeouts so a disconnected browser does not hang the session.

+# Frontend Compile Diagnostics
+
+Separate from runtime crash recovery.
+
+## First check the shadow-cljs build
+
+Use the Penpot MCP `cljs_compiler_output` tool to inspect the latest shadow-cljs `:main` build status. This is the fastest way to distinguish a bad build from a runtime error in the browser.
+
+Recommended order after CLJ/CLJC/CLJS source edits:
+1. Run `cljs_compiler_output`.
+2. If the compiler reports a Clojure syntax problem, especially unmatched delimiters or a confusing location, run `clj_check_parentheses` on the absolute path of the suspect `.clj`, `.cljc`, or `.cljs` file.
+3. After the build is healthy, use `mem:frontend/cljs-repl`, browser tools, or runtime crash checks for behavior.
+
+## Parentheses checker
+
+`clj_check_parentheses` analyzes one Clojure/ClojureScript source file and reports the area likely responsible for unclosed parentheses/brackets/braces. Use it when compiler output points near EOF, points at a misleading later form, or says delimiter-related syntax errors.
+
+## Hot reload notes
+
+When the frontend shadow-cljs watch process is running, edits to CLJC files in `common/` are normally recompiled into the browser automatically. Do not restart the frontend before checking `cljs_compiler_output`; stale behavior is often a failed build.
+
+For production/minified stack traces, build the production bundle from `frontend/` with `pnpm run build:app`. Output and source maps are generated under `frontend/resources/public/js`; inspect source maps or shadow-cljs reports using build ids from `shadow-cljs.edn`.

+# Frontend Dashboard and Viewer Subtleties
+
+## Dashboard
+
+- Dashboard initialization fetches projects and fonts for the team, then listens to websocket messages only for global topic `uuid/zero` or the current profile id.
+- Project fetch replaces each project map completely instead of merging, so fields such as `deleted-at` can disappear cleanly.
+- Dashboard file/project mutations are often optimistic local updates with fire-and-forget RPC watchers. Bulk permanent delete/restore paths use SSE progress and progress notifications.
+- File creation/duplication strips file `:data` before putting file summaries into dashboard state.
+
+## Viewer
+
+- Viewer initialization sets `:current-file-id`, `:current-share-id`, and `:viewer-local`, then fetches the view-only bundle. Comment threads are fetched only for logged-in users.

+# Frontend Runtime Crash Handling
+
+## Detect a runtime workspace crash
+
+Runtime crashes usually show the Internal Error page with title text "Something bad happened" and class `main_ui_static__download-link`. A common pattern is: changes go through via JS API / `execute_code`, then 1-2s later an `update-file` request reaches the backend and is rejected.
+
+After a crash, `execute_code` can become unusable because no plugin instances are connected and any data in its `storage` is lost, but `cljs_repl` usually still works.
+
+Check crash state:
+
+```clojure
+(some? (:exception @app.main.store/state))
+```
+
+It returns `true` when the Internal Error page is showing and `false` on a healthy workspace or after a successful reload.
+
+## Read the runtime cause
+
+The exception is stored at `(:exception @app.main.store/state)`. Useful keys:
+
+- `:type`, `:code`, `:status`: error class, e.g. `:validation`, `:referential-integrity`, `400`.
+- `:hint`, `:details`: human-readable explanation; `:details` often contains validation problems with `:shape-id`, `:page-id`, `:args`, etc.
+- `:uri`: API endpoint that returned the error, e.g. `update-file`.
+- `:app.main.errors/instance`: underlying JS Error object.
+- `:app.main.errors/trace`: JS stack trace string, usually response-handling path rather than the dispatch site that produced the bad change.
+
+```clojure
+(let [ex (:exception @app.main.store/state)]
+  (select-keys ex [:type :code :status :hint :details :uri]))
+```
+
+For backend validation errors (`:type :validation`), `:details` is usually the most informative field; it identifies the shape and invariant that failed.
+
+## Recover and continue testing
+
+Simplest path when `cljs_repl` is still live (usually true after a crash): reload via repl with `(.reload js/location)` — see `mem:frontend/cljs-repl`. Alternatively via Playwright: find the workspace tab (URL contains `/#/workspace`, title ends `- Penpot`), select it if not current, then `playwright:browser_navigate` to that same URL. Either way, confirm recovery with `(some? (:exception @app.main.store/state))` returning `false`.
+
+For backend-rejected changes, such as validation errors on `update-file`, changes are not persisted. Reload restores the pre-crash state, so it is safe to retry after fixing the cause.

+# Handling Errors and Debugging
+
+## Finding source errors
+
+You have access to two tools for finding errors in Clojure source code (which you may introduce yourself through edits):
+
+1. cljs_compiler_output
+2. clj_check_parentheses
+
+The latter is needed because syntax errors in parentheses give an uninformative compiler error, and the second
+tool can often find the exact location of such errors.
+
+When delimiter errors are detected (typically from lint or compiler output),
+fix the affected files with `tools/paren-repair.bb`. The `clj_check_parentheses`
+MCP tool can also pinpoint the error location when available, but it is not
+required — standard build errors are usually enough.
+See `mem:tools/paren-repair`.
+
+## Runtime patching with `set!`
+
+Some frontend vars are deliberately mutable escape hatches for runtime instrumentation or circular-dependency patching. 
+From `cljs_repl`, use `set!` for temporary debugging of CLJS vars such as 
+`app.main.store/on-event`, `app.main.errors/reload-file`, `app.main.errors/is-plugin-error?`, 
+`app.main.errors/last-report`, or `app.main.errors/last-exception`. 
+These patches affect only the live browser runtime and disappear on reload or recompilation.
+
+```clojure
+;; Log non-noisy Potok events temporarily.
+(set! app.main.store/on-event
+      (fn [event]
+        (when (potok.v2.core/event? event)
+          (.log js/console (potok.v2.core/repr-event event)))))
+```
+
+Restore mutable hooks after debugging, or reload the frontend. Use JVM `alter-var-root` only for JVM Clojure; 
+it is not the normal way to patch live CLJS browser vars.
+
+## Browser-console debug namespace
+
+In development, the JS console exposes `debug` helpers from `frontend/src/debug.cljs`:
+
+```javascript
+debug.set_logging("namespace", "debug");
+debug.dump_state();
+debug.dump_buffer();
+debug.get_state(":workspace-local :selected");
+debug.dump_objects();
+debug.dump_object("Rect-1");
+debug.dump_selected();
+debug.dump_tree(true, true);
+```
+
+Visual workspace debug overlays can be toggled with `debug.toggle_debug("bounding-boxes")`, `"group"`, `"events"`, or `"rotation-handler"`; `debug.debug_all()` and `debug.debug_none()` toggle all visual aids.
+
+For temporary source traces, prefer existing logging (`app.common.logging` / `app.util.logging`) or short-lived `prn`, `app.common.pprint/pprint`, `js/console.log`, or `js-debugger` calls. Remove temporary source instrumentation before committing.

+# Penpot Canvas → Playwright Viewport Coordinate Mapping
+
+## Goal
+Map Penpot shape coordinates (from the JS/ClojureScript API) to browser viewport CSS pixels
+so that Playwright mouse actions (click, drag, hover) can target specific canvas objects.
+
+## Key Facts
+
+### Playwright coordinate system
+Playwright mouse coordinates are **viewport CSS pixels**: `(0, 0)` is the top-left of the
+browser's rendered content area (not the screen, not the OS window chrome).
+`getBoundingClientRect()` returns the same coordinate system — they are directly compatible.
+
+### Canvas element location
+The Penpot canvas is rendered by two co-located elements:
+- `<canvas>` — the rasterised render
+- `<svg id="render">` — vector overlay
+- `<svg class="...viewport-controls ...">` — interaction/control layer (has the `viewBox`)
+
+Get the canvas origin with:
+```js
+document.querySelector("#render").getBoundingClientRect()
+// => { left: 318, top: 0, width: 514, height: 586, ... }  (values vary with window size/panels)
+```
+The left offset (currently ~318 px) is caused by the left-side panel (layers, assets).
+
+### Zoom and pan state
+Available in two equivalent ways:
+
+**1. App state (ClojureScript):**
+```clojure
+(let [wl (get @app.main.store/state :workspace-local)]
+  {:zoom  (get wl :zoom)    ; scale factor: penpot-units → CSS pixels
+   :vbox  (get wl :vbox)})  ; Rect {:x :y :width :height} — penpot coords of visible area
+```
+
+**2. SVG viewBox attribute (DOM):**
+```js
+document.querySelector("svg.viewport-controls, [class*='viewport-controls']")
+  .getAttribute("viewBox")
+// => "670 658.31 224 255.38"  i.e. "vbox.x vbox.y vbox.width vbox.height"
+```
+Both sources are live and always in sync.
+
+### Coordinate conversion formula
+```
+viewport_x = canvas_left  + (penpot_x - vbox.x) * zoom
+viewport_y = canvas_top   + (penpot_y - vbox.y) * zoom
+```
+
+Sanity check: `vbox.width * zoom ≈ canvas CSS width` (and same for height). ✓
+
+### Device Pixel Ratio
+The canvas physical pixel size = CSS size × DPR (observed DPR = 1.25, so canvas internal
+size 642×732 vs CSS size 514×586). This does **not** affect the formula — both
+`getBoundingClientRect()` and Playwright use CSS pixels.
+
+### Ruler label offset
+The on-screen rulers show coordinates offset from absolute Penpot coordinates (they display
+frame-relative values, offset by ~the top-level frame's x/y). **Ignore for coordinate
+mapping** — use `vbox` directly.
+
+---
+
+## ClojureScript Helper (paste into cljs REPL session)
+
+```clojure
+(defn penpot->viewport-coords
+  "Convert Penpot canvas coordinates to browser viewport CSS pixel coordinates.
+   Returns {:vp-x <number> :vp-y <number>} — pass directly to Playwright mouse actions."
+  [penpot-x penpot-y]
+  (let [state       @app.main.store/state
+        wl          (get state :workspace-local)
+        vbox        (get wl :vbox)
+        zoom        (get wl :zoom)
+        canvas      (js/document.querySelector "svg.viewport-controls, #render")
+        canvas-rect (.getBoundingClientRect canvas)]
+    {:vp-x (+ (.-left canvas-rect) (* (- penpot-x (:x vbox)) zoom))
+     :vp-y (+ (.-top  canvas-rect) (* (- penpot-y (:y vbox)) zoom))}))
+```
+
+Usage example — click the center of a shape:
+```clojure
+(let [shape   (get-in @app.main.store/state [:files file-id :data :pages-index page-id :objects shape-id])
+      cx      (+ (:x shape) (/ (:width shape) 2))
+      cy      (+ (:y shape) (/ (:height shape) 2))
+      {:keys [vp-x vp-y]} (penpot->viewport-coords cx cy)]
+  ;; pass vp-x, vp-y to Playwright page.mouse.click(vp-x, vp-y)
+  {:vp-x vp-x :vp-y vp-y})
+```
+
+---
+
+## JavaScript equivalent (for use in Playwright scripts directly)
+
+```js
+function penpotToViewport(penpotX, penpotY) {
+  // Read viewBox from the controls SVG (always in sync with app state)
+  const svg = document.querySelector('[class*="viewport-controls"]');
+  const [vbX, vbY, vbW, vbH] = svg.getAttribute('viewBox').split(' ').map(Number);
+  const rect = svg.getBoundingClientRect();
+  const zoom = rect.width / vbW;  // == rect.height / vbH
+  return {
+    x: rect.left + (penpotX - vbX) * zoom,
+    y: rect.top  + (penpotY - vbY) * zoom,
+  };
+}
+```
+
+This function can be injected and called via `page.evaluate()` in Playwright:
+```js
+const {x, y} = await page.evaluate(
+  ([px, py]) => penpotToViewport(px, py),
+  [penpotX, penpotY]
+);
+await page.mouse.click(x, y);

+# Driving Real User Gestures via Playwright
+
+Use Playwright when the bug or behavior depends on Penpot's real input pipeline: pointer gestures, keyboard modifiers, drag/drop targeting, modifier propagation, hover/focus behavior, or alt-drag duplication. The plugin JS API and `penpot:execute_code` can bypass these paths by dispatching store/API operations directly.
+
+## When `execute_code` Is Not Enough
+
+`execute_code` runs in the plugin sandbox. It is excellent for creating shapes, calling Plugin API methods, and querying design data, but it does not faithfully reproduce all user gestures. If the issue involves interactive transforms, frame targeting during drop, drag previews, modifier keys, or canvas hit-testing, drive the browser with Playwright and inspect results via cljs-repl.
+
+## Gesture Pattern
+
+A reliable drag gesture generally needs:
+- focus on the canvas first;
+- key modifiers held from before mouse down until after mouse up;
+- intermediate mouse move events, not just start/end;
+- short waits so Penpot's drag pipeline observes the gesture;
+- a trailing wait for the transaction to commit.
+
+Alt-drag duplication example:
+
+```javascript
+async (page) => {
+  await page.mouse.click(700, 700);
+  await page.waitForTimeout(200);
+
+  const startX = 821, startY = 565, endX = 821, endY = 815;
+  await page.keyboard.down('Alt');
+  await page.mouse.move(startX, startY);
+  await page.waitForTimeout(100);
+  await page.mouse.down();
+  await page.waitForTimeout(100);
+  for (let i = 1; i <= 10; i++) {
+    const t = i / 10;
+    await page.mouse.move(startX + (endX - startX) * t,
+                          startY + (endY - startY) * t);
+    await page.waitForTimeout(20);
+  }

+# Frontend Plugin API Runtime Subtleties
+
+## Type declarations vs runtime
+
+- The Plugin API is a public facade over internal frontend/common data. Do not expect Plugin API property names, value shapes, or behavior boundaries to match internal CLJS attrs or helper APIs; inspect the relevant proxy and internal code path before using Plugin API observations in production internals or tests.
+- `plugins/libs/plugin-types/index.d.ts` contains TypeScript declarations only. Runtime objects are CLJS proxies built under `frontend/src/app/plugins/*.cljs` with `obj/reify`.
+- `shape.cljs` builds shape proxies with hidden ids and per-property CLJS implementations. `library.cljs` builds library proxies such as `LibraryComponentProxy`.
+- `shape.cljs`, `library.cljs`, and related namespaces break circular dependencies with mutable nil vars patched from `app.plugins` at load time. If a proxy constructor appears nil, check the patching path in `frontend/src/app/plugins.cljs`.
+
+## Key Domain Namespaces
+- `app.common.types.component` (aliased `ctk`) — component predicates: `instance-root?`, `instance-head?`, `in-component-copy?`, `is-variant?`
+- `app.common.types.container` (aliased `ctn`) — container/tree operations: `in-any-component?`, `get-instance-root`, `get-head-shape`, `inside-component-main?`
+- `app.common.types.file` (aliased `ctf`) — file-level operations: `resolve-component`, `get-ref-shape`
+
+## Runtime initialization and permissions
+
+- The frontend initializes `@penpot/plugins-runtime` only after `features/initialize` and only when feature `plugins/runtime` is active. It also installs the runtime `isPluginError` predicate into frontend error handling.
+- Manifest parsing expands write permissions to read permissions (`content:write` => `content:read`, etc.). Permission checks also allow the all-zero plugin id and the hard-coded MCP plugin id.
+- Manifest URL origin differs by manifest version: v1 clears the path; v2 joins `.` to the plugin URL. Existing plugin ids are reused by matching manifest name and host.
+- The MCP plugin id is defined in `app.plugins.register` to avoid a circular dependency with workspace MCP code.
+
+## Proxy behavior
+
+- Public Plugin API objects are lightweight handles, not durable snapshots. Most getters locate fresh state from `app.main.store/state` using hidden `$id`, `$file`, `$page`, etc.
+- `not-valid` logs by default but throws when the plugin flag `throwValidationErrors` is enabled. The MCP execute-code handler deliberately enables that flag while running code.
+- `naturalChildOrdering` and `throwValidationErrors` are stored per plugin under `[:plugins :flags plugin-id ...]`; changing default behavior affects automation and MCP diagnostics.
+- Plugin data is stored under keyword namespaces: private data uses `(keyword "plugin" plugin-id)`, shared data uses `(keyword "shared" namespace)`.
+
+## Events and history
+
+- Plugin listeners are watches on the global store and callbacks are debounced about 10ms. Callback exceptions are caught and logged so plugin code does not crash the app.
+- `selectionchange` callbacks receive arrays of shape id strings, while `filechange`, `pagechange`, and `shapechange` return proxies.
+- `contentsave` fires only when persistence status transitions to `:saved`; it calls the callback with no value.
+- Plugin history `undoBlockBegin` creates a workspace undo transaction with a JS `Symbol`; `undoBlockFinish` commits that symbol. Missing finish eventually relies on the workspace transaction timeout.

+# Frontend Routing, App Shell, Websocket, and Error Subtleties
+
+## Router, app shell, and errors
+
+- Routing uses browser-history hash tokens, but `on-navigate` rejects navigation if the current origin/path does not match `cf/public-uri`.
+- Route params are split into `:path` and `:query`; duplicate query params can become vectors, so use `rt/get-query-param` when a scalar is required.
+- Unknown/empty routes trigger an extra `get-profile`/`get-teams` check before redirecting. This avoids invitation and root-route race conditions.
+- The root app renders an exception page from `:exception` state before the normal error boundary. `rt/navigated` clears `:exception`.
+- Frontend error handling treats stale cross-build JS chunk failures specially: messages containing `$cljs$cst$` or `$cljs$core$I` plus undefined/null/not-a-function signatures trigger throttled reload.
+- Plugin-originated uncaught errors are identified through the plugin runtime hook and logged rather than turning into the global exception page.
+
+## Store and websocket
+
+For general store mechanics such as `emit!`, `last-events`, persistence, and undo, read `mem:frontend/workspace-state-persistence-subtleties`.
+
+- Websocket initialization uses `cf/public-uri` joined with `ws/notifications`, converting `http/https` to `ws/wss`, and includes the current `session-id` as query param.
+- Reinitializing or finalizing websocket stops the previous receive stream. Incoming websocket payloads become Potok data events under `app.main.data.websocket/message`.

+# Frontend Testing and Live Verification
+
+Frontend validation: CLJS + React/Rumext + RxJS/Potok; SCSS modules; shared CLJC from `common/`.
+
+## Unit tests
+
+READ `mem:testing` FIRST — it defines the execution discipline (no piping, tee to file, preferred commands) that applies to all CLJS/JS test runs.
+
+Frontend unit tests live under `frontend/test/frontend_tests/` and use `cljs.test`. They should be deterministic, avoid DOM/UI integration where possible, and mock side effects such as RPC, storage, timers, or network access.
+
+From `frontend/`:
+- Full unit test run (always builds, suppressed output): `pnpm run test:quiet`.
+- Full unit test run (always builds, build output visible): `pnpm run test`.
+- Focus a frontend CLJS test namespace: `pnpm run test:quiet -- --focus frontend-tests.logic.components-and-tokens`.
+- Focus one frontend CLJS test var: `pnpm run test:quiet -- --focus frontend-tests.logic.components-and-tokens/change-spacing-token-in-main-updates-copy-layout`.
+- Quiet `app.*` logging during a run: append `--log-level warn` (or `trace|debug|info|warn|error`).
+- Build test target only (no run): `pnpm run build:test`.
+- After `build:test` has been run, run the compiled runner directly: `node target/tests/test.js [--focus ...] [--log-level ...]`.
+- Watch tests: `pnpm run watch:test`.
+
+New frontend test namespaces must be required/listed in `frontend_tests/runner.cljs`; new vars in existing namespaces need no runner change.
+
+## Playwright integration tests
+
+Do not add, modify, or run Playwright integration tests under `frontend/playwright` unless explicitly asked. When explicitly asked, use `pnpm run test:e2e` or `pnpm run test:e2e --grep "pattern"` from `frontend/`; ensure dependencies are installed through `./scripts/setup` if the environment is not prepared.
+
+Integration tests fake backend behavior by intercepting network/websocket traffic, so every RPC or websocket the page needs must be mocked. Use existing Page Object Models:
+- `BasePage.mockRPC` intercepts RPC calls and already prefixes `/api/rpc/command/`; pass command names such as `get-profile`, not full URLs.
+- Workspace or other websocket-using pages should extend/use `BaseWebSocketPage`, initialize websocket mocks before each test, and mock `/ws/notifications` with the provided helpers.
+- Prefer common locators/actions in POMs; ad-hoc locators can stay in a single test.
+
+Locator priority should follow user-facing semantics: `getByRole`, `getByLabel`, `getByPlaceholder`, `getByText`, then semantic alternatives such as alt/title, with `getByTestId` as the last resort. Name tests from the user's perspective and prefer positive, single-purpose assertions.
+
+## Live browser verification
+
+Because CLJC compiles to both JVM and CLJS, JVM/common tests can miss frontend-only state caused by browser runtime, WASM modifier math, or real pointer events. Use `mem:frontend/cljs-repl` to inspect live app state and `mem:frontend/playwright-gestures` when real input is needed.

+For stale hot reload or failed CLJ/CLJC/CLJS source builds, read `mem:frontend/compile-diagnostics`. For Internal Error pages or delayed runtime crashes after automation/API actions, read `mem:frontend/handling-crashes`.

+# Frontend UI Conventions and Style System
+
+## CLJS app UI
+
+- Main app components live under `frontend/src/app/main/ui*` and normally use Rumext `mf/defc` with a `*` suffix for component vars and `[:> component* props]` call sites.
+- Components should have clear ownership. Use `children` for normal composition; use slotted props only when separate owned regions are needed. Do not style or structurally manipulate child DOM that the component did not instantiate.
+- Accept and merge a `class` prop when callers reasonably need layout/positioning customization. Use `mf/spread-props` so Rumext prop transformations such as `:class` -> `className` still apply.
+- Avoid boolean prop names ending in `?`; they do not translate cleanly to JavaScript props. Use type hints such as `^boolean` where JS truthiness/semantics matter.
+- Split large components into smaller private components when useful; `::mf/private true` is the local convention for private Rumext components.
+
+## Styling
+
+- Co-located SCSS modules are preferred. Use `app.main.style/stl` helpers from CLJS and design-system SCSS tokens/mixins instead of legacy global selectors or high-specificity nesting.
+- Keep CSS specificity low. Avoid nested selectors unless they target elements the component owns; CSS Modules already prevent class-name collisions.
+- Prefer CSS logical properties for directional spacing/layout (`padding-inline-start`, etc.). Physical `width`/`height` are still acceptable where they are clearer.
+- Use named design-system variables/tokens for spacing, borders, fixed dimensions, colors, and typography. Avoid hardcoded px/rem values and deprecated `resources/styles/common/refactor/spacing.scss` variables.
+- Use component-local CSS custom properties for variants and theming instead of one-off Sass variables when a component has multiple visual states.
+- Prefer DS typography components (`heading*`, `text*`) and typography mixins instead of plain text wrappers or deprecated typography mixins.
+
+## Accessibility
+
+- Prefer semantic HTML first: anchors for navigation/download/email links, buttons for actions, correct heading levels, and keyboard-focusable controls.
+- If native elements cannot be used, apply appropriate ARIA roles/patterns. Follow WAI-ARIA APG patterns for standard widgets.
+- Icon-only controls need an accessible name via surrounding text, `aria-label`, `alt`, or equivalent. Decorative images/icons should be hidden from assistive tech.
+
+## I18n
+
+- Translations must be resolved during render or render-time memoization, not at namespace load time. For static option lists, memoize inside render so locale changes still update labels.
+- Translation files live in `frontend/translations/*.po`. Translation changes are bundled into `index.html`; refresh the browser after changing translations because there is no hot reload for translation strings.
+- Run `pnpm run translations` from `frontend/` after adding/updating translation text.
+- Adding a new supported locale requires updates in both `frontend/src/app/util/i18n.cljs` (`supported-locales`) and `frontend/scripts/_helpers.js` (`langs`).
+
+## Performance
+
+- Keep expensive derived data in refs, memoized selectors, or pure helpers. In hot render paths, prefer existing `app.common.data.macros` helpers where local code already uses them.
+- Avoid creating new callback functions/objects inside hot renders when a named function, memoized callback, data attribute, or precomputed JS props object works.
+- Destructure props/state values used repeatedly. Avoid repeated deref/property access in render loops.
+
+## Shared React UI package
+
+- `frontend/packages/ui` is the shared React/Vite package. It should remain framework-neutral relative to the CLJS app store; reusable primitives belong here only when they do not depend on Potok/Rumext app state.
+- Package styles are emitted through the package build and copied into `frontend/resources/public/css/ui.css`; stale shared styles are often a build artifact issue.
+- Storybook is the primary visual harness for shared UI/package behavior. Use `mem:frontend/ui-packages-text-editor-workflow` for package build/test commands.
+
+## Choosing a location
+
+- Put editor/dashboard/viewer workflow logic in CLJS app namespaces close to the owning feature.
+- Put reusable presentational React primitives in `frontend/packages/ui` when they can be consumed without Penpot app state.
+- Put CLJS design-system components under `frontend/src/app/main/ui/ds`; new DS components need implementation, CSS module, Storybook story, optional MDX docs, and export from `frontend/src/app/main/ui/ds.cljs` with a JavaScript-friendly name.
+- Put text editing internals in `frontend/text-editor` when the behavior belongs to the JS editor package; use `mem:common/text-subtleties` for shared text data-model behavior.
+
+## Validation
+
+- For CLJS app UI, use `mem:frontend/testing`, `mem:frontend/compile-diagnostics`, and live browser/REPL checks when behavior depends on store or canvas state.
+- For shared UI package changes, run the package build plus Storybook/component tests when relevant.
+- For text editor changes, run `frontend/text-editor` tests and refresh/copy WASM artifacts if render-wasm output is involved.

+
+## Package boundaries
+
+- `frontend/packages/ui` builds `@penpot/ui`, a React/Vite library package. It exports ESM and type declarations from `dist/`; React and ReactDOM are peer dependencies and must stay external in the Vite library build.
+- The UI package build copies generated `dist/index.css` into `frontend/resources/public/css/ui.css`. If shared UI styles look stale in the app, rebuild the package or check this copy step before debugging CLJS style code.
+- `frontend/text-editor` builds `@penpot/text-editor` from `src/editor/TextEditor.js`. It is a Vite JS package, not CLJS, and has its own Vitest/browser-test setup.
+- The text editor consumes render-wasm artifacts copied from `frontend/resources/public/js` into `frontend/text-editor/src/wasm`. Use `pnpm run wasm:update` after rebuilding `render-wasm` if tests or local dev use stale WASM files.
+- Other packages under `frontend/packages/` such as `tokenscript`, `draft-js`, and `mousetrap` are workspace dependencies used by the frontend app; do not assume their runtime behavior lives in CLJS namespaces.
+
+## Commands
+
+From `frontend/`:
+- Build app-side JS package assets: `pnpm run build:app:libs`.
+- Watch app-side JS package assets: `pnpm run watch:app:libs`.

+## Validation notes
+
+- Frontend root `check-fmt:js` covers stories, Playwright scripts, frontend scripts, and `text-editor/**/*.js`; it does not replace package-specific builds/tests.
+- Changes to shared UI package exports should be validated both in the package build and in the consuming app/Storybook path.

+# Frontend Workspace State and Persistence Subtleties
+
+## Store and interaction streams
+
+- `app.main.store/state` is the Potok store; `emit!` always returns nil. Store errors flow through the mutable `on-error` atom.
+- `last-events` keeps a filtered rolling buffer of about 50 event type strings and commit hint origins. It intentionally omits noisy websocket/persistence/pointer events.
+- `ongoing-tasks` controls `window.onbeforeunload`: any non-empty set blocks tab unload.
+- `app.main.streams/wasm-modifiers` and `workspace-selrect` are behavior subjects used for high-frequency interactive preview state that bypasses normal store updates and lenses.
+- Keyboard modifier streams merge a window blur signal so stuck modifier-key state is cleared after focus loss.
+
+## Repo calls
+
+- `app.main.repo/send!` uses GET only when the RPC name starts with `get-`, when all params are query params, or for configured special cases. Only GET requests are retried.
+- GET retry is limited to transient `:network`, `:bad-gateway`, `:service-unavailable`, and `:offline` errors with exponential backoff. Mutations are not retried.
+- A server SSE response is only accepted when the command is configured `:stream?`; otherwise it raises an unexpected-response assertion.
+
+## Commits, undo, persistence
+
+- `commit-changes` refuses to create commits unless `:permissions :can-edit` is true. It captures file revn/vern, selected-before, features, tags, undo group, and translation flag into a `::commit` event.
+- Applying a remote commit first rolls back pending local commits, applies the remote changes, then replays pending local redo changes. Index updates are emitted for undo, remote redo, and replayed redo paths.
+- Local commits are independently consumed by undo, persistence, WASM model updates, thumbnail/library watchers, and text position-data recalculation.
+- Persistence buffers local commits: status becomes pending after about 200ms, commits are flushed after about 3s or `::force-persist`, and buffered commits are merged per file before `:update-file`.
+- Persistence sends revn as the max of the commit revn and locally tracked latest revn; remote commits update that revn tracker.
+- Persistence is skipped in version preview/read-only mode or without edit permission.
+- Undo transactions can stay open only temporarily; timed-out pending transactions are force-committed after about 20s. Undo entries are capped at 50.
+- Undo/redo are ignored while a normal editor/drawing interaction is active, except grid-layout edition handles undo through this path.
+- After local commits and when render-wasm is active, text shapes get derived `:position-data` recomputed in a separate commit tagged `#{:position-data}`; that tag is excluded from the position-data watcher to avoid loops.
+
+## Refs
+
+- `refs/libraries` is explicitly deprecated for performance; prefer derefing `refs/files` and memoizing `select-libraries` in components.
+- `refs/workspace-page-objects` uses `identical?` equality, so preserving object map identity matters for avoiding derived-ref churn.
+- Selected-shapes refs use a small `{objects selected}` wrapper with custom equality before running `process-selected`; avoid bypassing that pattern in hot UI paths.

+# Frontend Workspace Token Subtleties
+
+## Token refs and visibility
+
+- Workspace token refs intentionally hide the internal hidden theme from theme trees/lists and expose active tokens through `get-tokens-in-active-sets`.
+- Token values stored on shapes are token names under `:applied-tokens`, not token ids. Renames/group renames must update those paths in common token logic.
+
+## Token application
+
+- Token application refuses to run while a text shape is in text-editing mode and shows a warning instead.
+- Applying a token writes token names into shape `:applied-tokens`, resolves active tokens through Style Dictionary or `tokenscript` depending on feature flags, updates concrete shape attrs, and wraps the operation in an undo transaction.
+- Applying composite typography removes atomic typography token attrs; applying atomic typography removes the composite typography token attr.
+- Spacing tokens have a special split path: layout containers receive gap/padding updates, while immediate children of layouts receive margin updates.
+
+## Propagation
+
+- Token propagation resolves active tokens, buffers many `update-shapes` commits, walks the current page first then the remaining pages, clears affected frame/component thumbnails, and drops `:position-data` for text shapes on non-current pages so it can be regenerated.

+# Frontend Workspace Transform Subtleties
+
+## Preview vs committed transforms
+
+- High-frequency previews use `app.main.streams/wasm-modifiers` and `workspace-selrect` behavior subjects instead of normal store commits; components consume them through refs that wrap plain atoms.
+- `apply-modifiers*` is the lower-level commit path once object/text modifiers are ready. It updates frame guides, frame comment threads, and then emits `update-shapes` with `:reg-objects? true`.
+- Transform commits restrict diff attrs to `transform-attrs` to avoid scanning unrelated shape attrs.
+- Text transforms may carry derived `:position-data`; `assoc-position-data` attaches it while preserving the original text shape context.
+
+## Component-copy touched suppression
+
+- `calculate-ignore-tree` walks modified shapes and descendants to decide per copy-shape `ignore-geometry?`.
+- `check-delta` compares a copy's relative position/rotation to its component root before and after transform. If relative movement is under about 1px and size/rotation are effectively unchanged, geometry touching is suppressed.
+- This logic is why pure translations of component copies can avoid marking every descendant as geometry-touched, while resizes/rotations still propagate touched state.
+
+## WASM bridge details
+
+- WASM modifier updates set plugin/local props with parsed geometry/structure modifiers rather than directly mutating file data.
+- The position-data recomputation watcher ignores commits tagged `:position-data`; keep that tag when adding derived position-data commits.
+- Rotation has separate WASM and non-WASM event paths. Check both when changing rotation modifier semantics.

+# Library Architecture and Workflow
+
+`library/`: builds `@penpot/library`; JS-facing in-memory Penpot file builder and `.penpot` ZIP exporter. Separate from main app runtime.
+
+## Layout and commands
+
+- Source: `library/src/`; tests: `library/test/`; experimentation/docs: `playground/`, `docs/`; config: `shadow-cljs.edn`, `deps.edn`, `package.json`.
+- From `library/`: build `pnpm run build`; bundle helper `pnpm run build:bundle` or `./scripts/build`; tests `pnpm run test`; watch `pnpm run watch` / `pnpm run watch:test`; lint `pnpm run lint`; format check/fix `pnpm run check-fmt` / `pnpm run fmt`.
+- When changing file-format construction or export behavior in `common/`, consider whether `@penpot/library` should be tested because it constructs Penpot files outside the app UI.
+- Cross-cutting testing principles and anti-patterns: `mem:testing`.
+
+## JS API and builder state
+
+- The JS build context wraps an atom and implements `IDeref`; `getInternalState` exposes the CLJ state converted to JS.
+- Public methods decode JS objects through the JSON transformer before calling common builder functions. Exceptions become JS `BuilderError` objects with enumerable `cause` and an `explain` getter for Malli explain data.
+- `create-build-context` can store an optional `referer`, later written into the export manifest.
+- The builder is stateful: call `addFile` before `addPage`. `addPage` resets the frame/group stack to the root and clears page-local naming state when the page closes.
+- `addBoard` and `addGroup` push onto the parent stack; matching close calls pop it. `closeGroup` requires at least one child and recalculates group geometry. Masked groups use the first child as mask and copy its geometry.
+- `commit-shape` emits `:add-obj` with `:ignore-touched true`, using the current parent, frame, and page from the stack.
+- Layer names are uniqued per current page; duplicate names get generated suffixes.
+- `addBool` converts an existing group into a bool shape and updates style/content/geometry via `:mod-obj` operations rather than adding a new object.
+- Media blobs are stored separately from file-media metadata; `add-file-media` requires a `BlobWrapper`.
+
+## Export package
+
+- `.penpot` ZIPs include `manifest.json`, file/page/shape JSON, components/colors/typographies/tokens, media metadata, and media object blobs.
+- Path/bool shape `:content` is converted to vectors before JSON encoding.
+- File export intentionally includes only selected top-level attrs plus data options; color export removes `:file-id` and drops empty paths.
+- Manifest type is `penpot/export-files`, version 1, generated by `penpot-library/%version%`, with optional referer and file relations.
+- Export generation is sequential and lazy: delayed JSON/blob work is computed only as each zip entry is written, and the progress callback receives `{total,item,path}` after each entry.
+- The library has compatibility defaults for features/migrations in the common builder; do not assume it always exports with the newest app-default migrations/features.

+# Penpot MCP
+
+This subproject provides an MCP server for Penpot integration.
+The MCP server communicates with a Penpot plugin via WebSockets, allowing
+the MCP server to send tasks to the plugin and receive results,
+enabling advanced AI-driven features in Penpot.
+
+## Tech Stack
+
+- Language: TypeScript
+- Runtime: Node.js
+- Framework: MCP SDK (@modelcontextprotocol/sdk)
+- Build Tool: TypeScript Compiler (tsc) + esbuild
+- Package Manager: pnpm
+
+## General Principles
+
+IMPORTANT: Use an idiomatic, object-oriented style.
+In particular, this implies that, for any non-trivial interfaces, you use interfaces that expect explicitly typed abstractions
+rather than mere functions (i.e. use the strategy pattern, for example).
+
+Comments:
+When describing parameters, methods/functions and classes, you use a precise style, where the initial (elliptical) phrase
+clearly defines *what* it is. Any details then follow in subsequent sentences.
+
+When describing what blocks of code do, you also use an elliptical style and start with a lower-case letter unless
+the comment is a lengthy explanation with at least two sentences (in which case you start with a capital letter, as is
+required for sentences).

+
+## Key Development Tasks
+
+### Adjusting the Prompts
+
+The system prompt file (aka Penpot High-Level Overview) is located in 
+`packages/server/data/initial_instructions.md`.
+
+### Adding a new Tool
+
+1. Implement the tool class in `packages/server/src/tools/` following the `Tool` interface.
+   IMPORTANT: Do not catch any exceptions in the `executeCore` method. Let them propagate to be handled centrally.
+2. Register the tool in `PenpotMcpServer`.
+
+Tools can be associated with a `PluginTask` that is executed in the plugin.
+Many tools build on `ExecuteCodePluginTask`, as many operations can be reduced to code execution.
+
+### Adding a new PluginTask
+
+1. Implement the input data interface for the task in `packages/common/src/types.ts`.
+2. Implement the `PluginTask` class in `packages/server/src/tasks/`.
+3. Implement the corresponding task handler class in the plugin (`packages/plugin/src/task-handlers/`).
+    * In the success case, call `task.sendSuccess`.
+    * In the failure case, just throw an exception, which will be handled centrally!
+4. Register the task handler in `packages/plugin/src/plugin.ts` in the `taskHandlers` list.
+
+## Dev Tooling
+
+From the `mcp/` directory, run
+
+* `pnpm run build` to test the build of all packages
+* `pnpm run fmt` to apply the auto-formatter
+* Cross-cutting testing principles and anti-patterns: `mem:testing`.
+
+## Devenv plugin/server wiring
+
+In the normal Penpot devenv MCP path, the browser plugin does not discover or route through Postgres. The frontend provides the plugin extension API with `mcp.getServerUrl()`, currently derived from `frontend/src/app/config.cljs` as `penpotMcpServerURI` if set, otherwise `<public-uri>/mcp/ws`. The MCP plugin opens a direct WebSocket to that URL and appends the current MCP access token as a query parameter.
+
+The live plugin connection registry is in-memory inside each MCP server process (`PluginBridge.connectedClients` / `clientsByToken`). The database only stores MCP access tokens and profile props such as `mcp-enabled`; it does not manage which plugin is connected to which MCP server.
+
+For parallel devenvs, prefer same-origin MCP routing: each Penpot instance should expose `/mcp/ws` through its own nginx/Caddy path to the MCP server running inside the same main container. Keep container-internal ports fixed (MCP defaults `4401/4402/4403`, backend/exporter/frontend defaults, etc.) and only offset host-side published ports per instance. If internal ports are offset, hardcoded local proxy config such as `docker/devenv/files/nginx.conf` will misroute unless templated too.

+# Memory Maintenance
+
+## Discovery Model
+
+- Core principle: progressive discovery through references, building a graph of memories.
+- Initially, agents are provided with the list of all memories (names only).
+- Agents should read `mem:critical-info` as the top-level entry point (graph root).
+  This memory should contain references to other memories covering major project domains.
+  The referenced memories shall, in turn, shall contain references to even more specific memories, and so on.
+  The depth of the graph shall depend on the project complexity.
+- Use topics/folders to group related memories in order to make the content structure explicit.
+  Folders can mirror project structure (e.g. modules like frontend/backend) or topics like debugging, architecture, etc.
+- Memory references must use a mem: prefix inside backticks, e.g. `mem:frontend/core`.
+  The surrounding text should clearly indicate when to read the memory/which content to expect.
+  The text should provide more precise guidance than the memory name alone,
+  i.e. avoid a reference like "frontend debugging and error handling: `mem:frontend/handling-errors-and-debugging` and instead make clear which concrete aspects are covered in the memory.
+- Memories themselves should not contain information about when to read them; this is the responsibility of the referring memory.
+
+## Style
+
+Dense agent notes, not prose docs. Prefer invariants, terse bullets.
+Avoid obvious context, rationale, and examples unless they prevent likely mistakes.
+Keep guidance durable and generalizable, not task-local.
+
+## Add/update threshold
+
+Add or update memories only with stable, non-obvious project conventions that avoid complex rediscovery in the future.
+Do not add: quick-read facts; generic language/framework knowledge; one-off task notes; volatile line-level details; behavior likely to change soon.
+
+## Maintenance Actions
+
+- Renaming memories: References are updated automatically if handled via Serena's memory rename tool.
+- Checking for stale memories (e.g. after deletion): Call `serena memories check` for a report.

+# Plugins Architecture and Workflow
+
+`plugins/`: standalone TypeScript/pnpm workspace for Plugin API packages and sample plugins. Related to, distinct from, frontend CLJS Plugin API runtime.
+
+## Layout
+
+- `libs/plugin-types`: TypeScript declarations for the public Penpot Plugin API. Type-only package; runtime behavior is implemented elsewhere.
+- `libs/plugins-runtime`: runtime that loads plugins and exposes/generated API behavior to plugin code.
+- `libs/plugins-styles`: reusable styling package for plugins.
+- `apps/*-plugin`: sample/development plugins. `apps/e2e`: plugin e2e tests.
+
+## Dev Workflow
+
+- From `plugins/`: install `pnpm -r install`; runtime dev server `pnpm run start` or `pnpm run start:app:runtime`; sample plugin `pnpm run start:plugin:<name>`; build runtime `pnpm run build:runtime`; build plugins `pnpm run build:plugins`; lint `pnpm run lint`; format `pnpm run format:check` / `pnpm run format`; tests `pnpm run test`; e2e `pnpm run test:e2e`.
+- If a change affects public Plugin API types or runtime, update `plugins/CHANGELOG.md`. Prefix type/signature entries with `**plugin-types:**`; runtime behavior entries with `**plugin-runtime:**`.
+- Cross-cutting testing principles and anti-patterns: `mem:testing`.
+- JS Plugin API behavior inside Penpot app: `mem:frontend/plugin-api-to-cljs-binding`; TS declarations are not runtime code; many API objects are CLJS proxies in `frontend/src/app/plugins/*.cljs`.
+
+## Sandbox and global cleanup
+
+- The runtime uses SES compartments. Public API return values are passed through `ses.safeReturn` before crossing back to plugin code.
+- Plugin `fetch` is sanitized: credentials are omitted and Authorization is blanked. The exposed response only includes ok/status/statusText/url/text/json.
+- Timer callbacks are wrapped to mark plugin-originated errors, and timeout/interval IDs are tracked so plugin close can clear them.
+- Plugin-originated errors are tracked in a WeakMap instead of mutating error objects, because SES can freeze errors.
+- Closing a plugin removes public API keys from the compartment globalThis.
+
+## Lifecycle
+
+- Loading a plugin closes existing non-background plugins and resets the runtime registry. Be careful around `allowBackground` semantics when changing load/close behavior.
+- If sandbox evaluation fails, the runtime marks the error as plugin-originated, closes the plugin, and rethrows.
+- `plugin-manager` removes event listeners, timers, intervals, and modal state on close, and marks the plugin destroyed. Listener callbacks check that flag because Penpot events can fire after close.
+
+## Modal/UI behavior
+
+- Modal URL preparation differs by manifest version: v1 uses query string parameters, v2 puts parameters in the URL hash.
+- `openModal` is idempotent for the same iframe source and avoids reopening when the target URL is already displayed.
+- Modal permissions are derived from manifest permissions (`allow:downloads`, `clipboard:read`, `clipboard:write`).
+- `resizeModal` clamps to at least 200x200 and at most the window minus margins, adjusting transform so the modal remains in the viewport.

+# Production infrastructure (services Penpot depends on)
+
+Backend (`app.config`, `PENPOT_*` env vars) is parameterized; deployments choose providers.
+
+## Services
+
+- **PostgreSQL**: durable store. Profiles, teams, files, sessions, audit, `storage_object` metadata, the `task` queue, `scheduled_task` cron registry, migrations. File-data also lives here when the file-data backend is `legacy-db`/`db`. One shared DB across all backends.
+- **Redis (Valkey-compatible)**: per-backend message bus and cache. Concrete uses: msgbus Pub/Sub for collaborative-editing broadcasts and team/profile-org notifications fired by RPC handlers (`app.rpc.notifications`, `files_update`, `teams`, `websocket`); file-summary cache gated by `enable-redis-cache`; rate-limit counters; and the dispatcher→runner work hand-off list `penpot.worker.queue:<tenant>:<queue>`. `PENPOT_REDIS_URI`.
+- **Object storage**: backends `:s3` and `:fs`. S3 in prod; devenv uses MinIO. Holds uploaded media, file-data when the file-data backend is `storage`, exports. Backend-side details (resolve, dedup, bucket set, file-data backends): `mem:backend/http-storage-filedata-subtleties`.
+- **SMTP mailer**: invitations, password resets, email verification (sent via the `:sendmail` worker task).
+- **LDAP** (optional auth provider): helpers in `app.auth.*`, gated by `enable-login-with-ldap`.
+
+## Task queue and worker model
+
+Async tasks are enqueued via `wrk/submit!` (`app.worker`), which inserts a row into the shared Postgres `task` table tagged with `queue = "<tenant>:<queue-name>"`. Submission is **fire-and-forget** — RPC handlers never poll, never wait, and workers never publish to msgbus. The only completion signal is the `task` row's `status` / `completed_at` columns, which nothing in `rpc/` reads. Soft-delete RPCs return immediately after marking the top-level row, leaving the cascade and reaping to workers.
+
+Workers run on backends with `enable-backend-worker` in `PENPOT_FLAGS`. Each worker-enabled backend has a `dispatcher` (polls `task` with `FOR UPDATE SKIP LOCKED`, marks status='scheduled', RPUSHes claimed task IDs into **its own** Redis list) and one or more `runner`s per queue (BLPOP from that same local list, execute, update the Postgres row). The Redis hand-off list is purely intra-backend — cross-backend coordination happens at the Postgres row level.
+
+## Cross-backend safety
+
+Postgres row locking is the only correctness primitive: `task` claims via `FOR UPDATE SKIP LOCKED`, cron firing via `FOR UPDATE SKIP LOCKED` on the `scheduled_task` row, plus task-handler-internal locks (e.g. `file_gc_scheduler` locks candidate file rows). This makes the work-claim path safe across any number of worker-enabled backends.
+
+Two known race patterns survive multi-backend operation:
+
+- **Cron dedup is best-effort.** The lock on `scheduled_task` is released when the task body finishes. If two backends' cron timers fire for the same scheduled instant with a gap larger than the task body's runtime, both execute it. Penpot's cron entries are idempotent (`session-gc`, `objects-gc`, `storage-gc-*`, `tasks-gc`, `upload-session-gc`, `file-gc-scheduler`); the exceptions are `:telemetry` (would double-report) and `:audit-log-archive` (depends on archive target idempotency).
+- **`wrk/submit! ::dedupe true`** does a non-atomic `DELETE` then `INSERT`. Concurrent cross-backend submits can both bypass the `DELETE` (each sees the other's uncommitted insert as absent) and end up with duplicate `'new'` rows. Each row claims and runs once independently, so the underlying work is fine; the "at most one pending" guarantee weakens.
+
+Penpot in production lives with both: horizontal-scale deployments accept "exactly-once" as "essentially-once for idempotent operations." Devenv parallel instances handle it by running workers only on ws0 (see `mem:devenv/core`).

+- Exported functions live around `src/main.rs` / `src/wapi.rs` and are called from ClojureScript bridge namespaces under `frontend/src/app/render_wasm*`.
+- Updates are two-phase: ClojureScript calls exported setters to push shape data, then `render_frame()` performs Skia drawing.

+# render-wasm FFI and Rendering Subtleties
+
+## FFI state and errors
+
+- The renderer uses one unsafe global `STATE`; the `with_state*` macros currently panic on invalid state pointer. Treat state pointer validity as critical, not recoverable.
+- `#[wasm_error]` clears the error code on entry. Recoverable errors set code `0x01`, critical errors/panics set `0x02`, free the byte buffer, then panic so the CLJS bridge can catch and inspect `_read_error_code`.
+- The frontend bridge maps `0x01` to `:non-blocking` and `0x02` to `:panic` in ex-data (`:type :wasm-error`). Check actual bridge code if changing names; older comments/docs may use different labels.
+- WASM byte transfer is a single global slot. A caller that receives a pointer result must read and free it before another byte payload is written; errors free the slot via `#[wasm_error]`.
+
+## Shape pool and loading
+
+- Shapes are UUID-indexed, and hierarchy/structure is tracked separately. `ShapesPool::get` may return a cached modified clone when modifiers, structure, scale-content, or bool handling apply; `get_raw` bypasses those derived values.
+- Bulk loading uses a `loading` flag. `touch_current` / `touch_shape` avoid tile invalidation while loading; text layouts and final view setup must happen after loading ends.
+- Many setters mutate only the current shape selected by `use_shape` / current-shape APIs. If no current shape is selected, some mutation blocks are skipped silently.
+- `set_parent_for_current_shape` only sets parent metadata and invalidates parent geometry; children must be updated separately to avoid duplicate children.
+- Child deletion marks descendants deleted and removes them from all indexed tiles, preserving undo/redo while avoiding stale pixels after panning.
+
+## Tile/render behavior
+
+- Interactive transforms are distinct from viewport fast mode. `set_modifiers_start` enables fast mode and interactive transform; interactive transform still flushes each animation frame.
+- During interactive transform, modifier tile invalidation is deferred to `render()` once per rAF. Outside interactive transform, `set_modifiers` rebuilds modifier tiles immediately.
+- `set_modifiers_end` disables fast/interactive state and cancels pending async render; the caller must request the final full-quality render.
+- Plain viewport fast mode (`options.is_viewport_interaction()`) renders from cache and does not flush target output inside `process_animation_frame`; interactive transforms do flush.
+- Zoom changes rebuild the tile index while preserving cached tile textures. Avoid replacing that path with shallow rebuilds if blur/shadow cache preservation matters.
+- Pending tile priority is intentionally reversed by pop order; check the queue construction before changing tile scheduling.

+# Testing
+
+## Overview
+
+Tests are proof that code works. Every behavior change needs a test.
+
+Testing in this monorepo varies by module. Each module has its own test
+commands, helpers, runner registration requirements, and conventions. This
+memory covers cross-cutting testing principles. For module-specific commands
+and helpers, consult:
+
+- `mem:common/testing` — CLJC unit tests (JVM + JS), test helpers, fixture
+  builders, production-path change helpers
+- `mem:frontend/testing` — CLJS unit tests, Playwright E2E integration tests,
+  live browser verification via nREPL
+- Backend — JVM `clojure.test` under `backend/test/`; see `mem:backend/core`
+
+## When to Use
+
+- Implementing new logic or behavior
+- Fixing any bug (reproduction test required)
+- Modifying existing functionality
+- Adding edge case handling
+
+**When NOT to use:** Pure configuration changes, documentation updates, or
+static content changes with no behavioral impact.
+
+## TDD: Recommended Workflow
+
+Write a failing test before writing the code that makes it pass. For bug fixes,
+reproduce the bug with a test before attempting a fix.
+
+When TDD isn't practical (exploratory work, tight coupling to unknown APIs),
+still write tests before considering the work complete.

+   Test FAILS        Test PASSES         Tests still PASS
+```
+
+- **RED** — Write the test first. It must fail. A test that passes immediately
+  proves nothing.
+- **GREEN** — Write the minimum code to make the test pass. Don't over-engineer.
+- **REFACTOR** — With tests green, improve the code without changing behavior:
+  extract shared logic, improve naming, remove duplication. Run tests after
+  every step.
+
+## The Prove-It Pattern (Bug Fixes)
+
+When a bug is reported, **do not start by trying to fix it.** Start by writing
+a test that reproduces it:
+
+1. Write a test that demonstrates the bug
+2. Confirm the test FAILS (proving the bug exists)
+3. Implement the fix
+4. Confirm the test PASSES (proving the fix works)
+5. Run the full test suite for the module (no regressions)
+
+## Core Principles
+
+- **Test State, Not Interactions** — assert on outcomes, not method calls;
+  survives refactoring
+- **DAMP over DRY** — tests are specifications; duplication is OK if each test
+  is self-contained and readable. A test should tell a complete story without
+  requiring the reader to trace through shared helpers.
+- **Prefer Real Implementations** — hierarchy: Real > Fake > Stub > Mock;
+  mock only at boundaries (network, RPC, filesystem, email)
+- **Arrange-Act-Assert** — every test: setup / action / verify
+- **One Assertion Per Concept** — each test verifies one behavior; split
+  compound assertions
+- **Descriptive Test Names** — names read like specifications
+
+## Prefer Real Implementations Over Mocks
+
+Work down this list:
+
+1. **Real implementation** — Test the actual code with real collaborators.
+   Highest confidence.
+2. **Fake** — A simplified but functional in-memory implementation (e.g.
+   atom/dict-backed store instead of a real database).
+3. **Stub** — Returns canned data. Use when the collaborator's logic is
+   irrelevant.
+4. **Mock** — Last resort, only at boundaries. Use only when verifying
+   interaction with an external system that cannot be faked.
+
+**Rule of thumb:** If you can write a fake or use the real implementation, do
+that. If you find yourself asserting on call counts or invocation order, ask
+whether a fake would be clearer.
+
+## Fixtures over Manual Setup
+
+Use fixture/`beforeEach` mechanisms for shared setup and teardown. Each test
+should own its state so tests don't interfere with each other. Shorter-scope
+fixtures (`:each` / per-test) are preferred; longer-scope fixtures (`:once` /
+suite-level) are only for expensive, immutable shared setup.
+
+## Parametrized Tests
+
+Use your test framework's parametrize/table-driven mechanism to test multiple
+scenarios with a single test body. Keeps tests concise and surfaces all cases
+at a glance.
+
+## Test Pyramid
+
+```
+          ╱╲
+         ╱  ╲         E2E (few)
+        ╱    ╲        Full flows, real browser/server
+       ╱──────╲
+      ╱        ╲      Integration (some)
+     ╱          ╲     Cross-module, test DB
+    ╱────────────╲
+   ╱              ╲   Unit (most)
+  ╱                ╲  Pure logic, fast
+ ╱──────────────────╲
+```
+
+Prefer unit tests for pure logic. Reach for integration/E2E tests when covering
+RPC handlers, database queries, or full user flows. In the frontend, Playwright
+E2E tests should not be added unless explicitly requested.
+
+## Anti-Patterns
+
+| Anti-Pattern | Problem | Fix |
+|---|---|---|
+| Testing implementation details | Breaks on refactor | Test inputs/outputs |
+| Flaky tests (timing, order-dependent) | Erodes trust | Deterministic assertions, isolate state |
+| Mocking everything | Tests pass, production breaks | Prefer real implementations or fakes |
+| No test isolation | Pass individually, fail together | Per-test state fixtures |
+| Testing framework/platform code | Wastes time | Only test YOUR code |
+| Snapshot abuse | Nobody reviews, break on any change | Focused assertions |
+| Skipping tests to make suite pass | Hides real failures | Fix the test or fix the code |
+
+## Execution discipline
+
+When running CLJS/JS tests (frontend, common):
+
+- **Always use `pnpm run test:quiet`** — it silently builds the test bundle then runs the test runner, giving you clean test output.
+- **Never pipe test output through `tail`, `head`, or similar filters** — doing so can silently hide test failures. Use `--focus` to narrow scope instead.
+- **If you need to filter output, tee to a temp file first:** `pnpm run test:quiet 2>&1 | tee /tmp/penpot-test-output.txt`. The full output is preserved on disk so you can `grep`/`tail`/`head` the file without re-running.
+- Use `pnpm run test` when you want to see build output alongside test results (always builds, then runs).
+- After `build:test` has been run once, you can invoke the runner directly: `node target/tests/test.js [--focus ...] [--log-level ...]`.
+
+When running JVM tests (backend, common):
+- Use `clojure -M:dev:test` directly (no pnpm wrapper).
+- The same no-piping rule applies: use `--focus` to narrow scope.
+
+## Verification Checklist
+
+After completing any implementation:
+
+- [ ] Every new behavior has a corresponding test
+- [ ] All tests pass for touched modules
+- [ ] Bug fixes include a reproduction test that failed before the fix
+- [ ] Test names describe the behavior being verified
+- [ ] No tests were skipped or disabled
+- [ ] Lint/formatter passes for touched modules
+- [ ] New test files registered in the module's runner/entrypoint (see module
+      testing memory)

+# nREPL Eval
+
+Evaluate Clojure (or ClojureScript) code via a running nREPL server using
+`tools/nrepl-eval.mjs` — a standalone CLI application.
+
+Session state (defs, in-ns, etc.) persists across invocations via a stored
+session ID, so you can build up state incrementally.
+
+## Usage
+
+```bash
+node tools/nrepl-eval.mjs [options] [<code>]
+# or
+./tools/nrepl-eval.mjs [options] [<code>]
+```
+
+## Options
+
+| Flag | Description | Default |
+|------|-------------|---------|
+| `--backend` | Connect to backend nREPL (port 6064) | — |
+| `--frontend` | Connect to frontend nREPL (port 3447) | — |
+| `-p, --port PORT` | nREPL server port | `6064` |
+| `-H, --host HOST` | nREPL server host | `127.0.0.1` |
+| `-t, --timeout MS` | Timeout in milliseconds | `120000` |
+| `--reset-session` | Discard stored session and start fresh | — |
+| `-e, --last-error` | Evaluate `*e` to retrieve the last exception | — |
+| `-h, --help` | Show help message | — |
+
+- `--backend` and `--frontend` are mutually exclusive.
+- Explicit `--port` is overridden when `--backend`/`--frontend` is used.
+
+## When to Use
+
+1. **Evaluate Clojure code** during development — test functions, inspect
+   state, or run experiments against a running Clojure process.
+2. **Verify that edited files compile** — require namespaces with `:reload`
+   to pick up changes.
+3. **Inspect the last exception** after a failed evaluation — use `-e` to
+   print the error stored in `*e`.
+
+## Workflow
+
+### Session management
+
+Sessions are persisted to `/tmp/penpot-nrepl-session-<host>-<port>`. State
+carries across calls automatically:
+
+```bash
+./tools/nrepl-eval.mjs '(def x 42)'
+./tools/nrepl-eval.mjs 'x'
+# => 42
+```
+
+Reset the session to start fresh:
+
+```bash
+./tools/nrepl-eval.mjs --reset-session '(def x 0)'
+```
+
+### Evaluate code
+
+**Single expression (inline) — uses default port 6064:**
+```bash
+./tools/nrepl-eval.mjs '(+ 1 2 3)'
+```
+
+**Backend nREPL (explicit):**
+```bash
+./tools/nrepl-eval.mjs --backend '(+ 1 2 3)'
+```
+
+**Frontend nREPL:**
+```bash
+./tools/nrepl-eval.mjs --frontend '(js/alert "hi")'
+```
+
+**Multiple expressions via heredoc (recommended — avoids escaping issues):**
+```bash
+./tools/nrepl-eval.mjs <<'EOF'
+(def x 10)
+(+ x 20)
+EOF
+```
+
+**Override with a different port:**
+```bash
+./tools/nrepl-eval.mjs -p 7888 '(+ 1 2 3)'
+```
+
+### Inspect last exception
+
+After code throws an error, retrieve the full exception details:
+
+```bash
+./tools/nrepl-eval.mjs -e
+```
+
+## Common Patterns
+
+**Require a namespace with reload:**
+```bash
+./tools/nrepl-eval.mjs "(require '[my.namespace :as ns] :reload)"
+```
+
+**Test a function:**
+```bash
+./tools/nrepl-eval.mjs "(ns/my-function arg1 arg2)"
+```
+
+**Long-running operation with custom timeout:**
+```bash
+./tools/nrepl-eval.mjs -t 300000 "(long-running-fn)"
+```
+
+## Key Principles
+
+- **Default port is 6064** — just pass code directly, no `-p` needed when
+  your nREPL server is on 6064. Use `--backend` (6064) or `--frontend` (3447)
+  as quick aliases. Use `-p <PORT>` for any other port.
+- **Always use `:reload`** when requiring namespaces to pick up file changes.
+- **Session is reused** across invocations — defs, in-ns, and var bindings
+  persist. Use `--reset-session` to clear.
+- **Do not start any server** — the tool connects to an existing nREPL
+  server, it is not the agent's responsibility to start the nREPL server
+  (assume the server is already running on the specified port).
