fix(distributed): stop queue loops on agent nodes + dead-letter cap

pending_backend_ops rows targeting agent-type workers looped forever:
the reconciler fan-out hit a NATS subject the worker doesn't subscribe
to, returned ErrNoResponders, we marked the node unhealthy, and the
health monitor flipped it back to healthy on the next heartbeat. Next
tick, same row, same failure.

Three related fixes:

1. enqueueAndDrainBackendOp skips nodes whose NodeType != backend.
   Agent workers handle agent NATS subjects, not backend.install /
   delete / list, so enqueueing for them guarantees an infinite retry
   loop. Silent skip is correct — they aren't consumers of these ops.

2. Reconciler drain mirrors enqueueAndDrainBackendOp's behavior on
   nats.ErrNoResponders: mark the node unhealthy before recording the
   failure, so subsequent ListDuePendingBackendOps (filters by
   status=healthy) stops picking the row until the node actually
   recovers. Matches the synchronous fan-out path.

3. Dead-letter cap at maxPendingBackendOpAttempts (10). After ~1h of
   exponential backoff the row is a poison message; further retries
   just thrash NATS. Row is deleted and logged at ERROR so it stays
   visible without staying infinite.

Plus a one-shot startup cleanup in NewNodeRegistry: drop queue rows
that target agent-type nodes, non-existent nodes, or carry an empty
backend name. Guarded by the same schema-migration advisory lock so
only one instance performs it. The guards above prevent new rows of
this shape; this closes the migration gap for existing ones.

Tests: the prune migration (valid row stays, agent + empty-name rows
drop) on top of existing upsert / backoff coverage.

-## Importer integration
-
-When you add a new backend, you MUST also make it importable via the model import form (`/import-model`). The import form dropdown is sourced dynamically from `GET /backends/known` — it reads the importer registry at `core/gallery/importers/importers.go`, so the steps below are the ONLY way to make your backend show up.
-
-Required steps:
-
-1. **If your backend has unambiguous detection signals** (unique file extension, HF `pipeline_tag`, unique repo name pattern, unique artefact like `modules.json`):
-   - Create an importer file at `core/gallery/importers/<backend>.go` following the Match/Import pattern in `llama-cpp.go`.
-   - Register it in `importers.go:defaultImporters` in **specificity order** — more specific detectors must appear BEFORE more generic ones (e.g. `sentencetransformers` before `transformers`, `stablediffusion-ggml` before `llama-cpp`, `vllm-omni` before `vllm`). First match wins.
-2. **If your backend is a drop-in replacement** (same artefacts as another backend, e.g. `ik-llama-cpp` and `turboquant` both consume GGUF the same way `llama-cpp` does):
-   - Do NOT create a new importer. Extend the existing importer's `Import()` to swap the emitted `backend:` field when `preferences.backend` matches. See `llama-cpp.go` for the pattern.
-3. **If your backend has no reliable auto-detect signal** (preference-only — e.g. `sglang`, `tinygrad`, `whisperx`):
-   - Do NOT create an importer. Instead add the backend name to the curated pref-only slice in `core/http/endpoints/localai/backend.go` that feeds `/backends/known`. A single line addition.
-4. **Always** add a table-driven test in `core/gallery/importers/importers_test.go` (Ginkgo/Gomega):
-   - Use a real public HuggingFace repo URI as the test fixture (existing tests already hit the live HF API — follow that pattern).
-   - Cover detection (auto-match without preferences), preference-override (explicit `backend:` in preferences wins), and — if the backend's modality has a common `pipeline_tag` but ambiguous artefacts — an ambiguity test asserting `errors.Is(err, importers.ErrAmbiguousImport)`.
-
-Rules of thumb:
-
-- When in doubt, lean pref-only. A wrong auto-detect is worse than a forced preference.
-- Never silently emit a modality mismatch (e.g. emit `llama-cpp` for a TTS repo because `.gguf` is present). Return `ErrAmbiguousImport` instead.
-- Registration order is the single most common source of bugs. Check by running `go test ./core/gallery/importers/...` — the existing suite will fail if you've shadowed a pre-existing detector.

 This guide covers how to add new API endpoints and properly integrate them with the auth/permissions system.
 
-> **Before you ship a new endpoint or capability surface**, re-read the [checklist at the bottom of this file](#checklist). LocalAI advertises its feature surface in several independent places — miss any one of them and clients/admins/UI won't know the endpoint exists.
-
 ## Architecture overview
 
 Authentication and authorization flow through three layers:
@@ -236,66 +234,6 @@ Use these HTTP status codes:
 
 If your endpoint should be tracked for usage (token counts, request counts), add the `usageMiddleware` to its middleware chain. See `core/http/middleware/usage.go` and how it's applied in `routes/openai.go`.
 
-## Advertising surfaces — where to register a new capability
-
-Beyond routing and auth, LocalAI publishes its capability surface in **four independent places**. When you add an endpoint — especially one introducing a net-new capability like a new media type or a new auth-gated feature — you must update every relevant surface. These aren't optional: missing them means the endpoint works but is invisible to clients, admins, and the UI.
-
-### 1. Swagger `@Tags` annotation (mandatory)
-
-Every handler needs a swagger block so the endpoint appears in `/swagger/index.html` and in the `/api/instructions` output. The `@Tags` value is what groups the endpoint into a capability area:
-
-```go
-// MyEndpoint does X.
-// @Summary Do X.
-// @Tags my-capability
-// @Param request body schema.MyRequest true "payload"
-// @Success 200 {object} schema.MyResponse "Response"
-// @Router /v1/my-endpoint [post]
-func MyEndpoint(...) echo.HandlerFunc { ... }
-```
-
-Use an existing tag when the endpoint extends an existing area (e.g. `audio`, `images`, `face-recognition`). Create a new tag only when the endpoint introduces a genuinely new capability surface — and in that case, also register it in step 2.
-
-After adding endpoints, regenerate the embedded spec so the runtime serves it:
-
-```bash
-make protogen-go         # ensures gRPC codegen is fresh first
-make swagger             # regenerates swagger/swagger.json
-```
-
-### 2. `/api/instructions` registry (for new capability areas)
-
-`core/http/endpoints/localai/api_instructions.go` defines `instructionDefs` — a lightweight, machine-readable index of capability areas that groups swagger endpoints by tag. It's the primary discovery surface for agents and SDKs ("what can this server do?").
-
-**When to update:** only when adding a new capability area (a new swagger tag). Existing-tag additions automatically surface without any change here.
-
-Add an entry to `instructionDefs`:
-
-```go
-{
-    Name:        "my-capability",             // URL segment at /api/instructions/my-capability
-    Description: "Short sentence describing the capability",
-    Tags:        []string{"my-capability"},   // must match swagger @Tags
-    Intro:       "Optional gotcha/context that isn't in the swagger descriptions (caveats, defaults, cross-references to other endpoints).",
-},
-```
-
-Also bump the expected-length count in `api_instructions_test.go` and add the name to the `ContainElements` assertion.
-
-### 3. `capabilities.js` symbol (for new model-config FLAG_* flags)
-
-If your feature needs a new `FLAG_*` usecase flag in `core/config/model_config.go` (so users can filter gallery models by it, and so `/v1/models` surfaces it), also declare the matching symbol in `core/http/react-ui/src/utils/capabilities.js`:
-
-```js
-export const CAP_MY_CAPABILITY = 'FLAG_MY_CAPABILITY'
-```
-
-React pages that want to filter the ModelSelector by capability import this symbol. Declare it even if you're not building the UI page yet — the declaration keeps the Go/JS vocabularies in sync.
-
-### 4. `docs/content/` (user-facing documentation)
-
-A new capability deserves its own page under `docs/content/features/`, plus cross-links from related features and an entry in `docs/content/whats-new.md`. See the pattern used by `face-recognition.md` / `object-detection.md`.

-- **Tool added.** The new endpoint is something an admin would manage conversationally (install, list, edit, toggle, upgrade).

-- **Tool deliberately skipped.** The endpoint is internal/diagnostic and adding a chat path would be misleading. Document the decision in the PR description; no code action.
-- **Forgot.** This breaks the contract. The `TestToolHTTPRouteMappingComplete` test in `pkg/mcp/localaitools` is a partial guard (it checks every `Tool*` has a route mapping), but it does NOT detect new REST endpoints without a tool — that's still a process check on the PR author.

-# CI Build Caching
-
-Container builds — both the root LocalAI image (`Dockerfile`) and the per-backend images (`backend/Dockerfile.*`) — share a registry-backed BuildKit cache. This file explains how that cache is laid out, what invalidates it, and how to bypass it.
-
-## Cache layout
-
-- **Cache registry**: `quay.io/go-skynet/ci-cache`
-- **Tag prefixes**:
-  - Backend builds (`backend_build.yml`) buildkit cache: `cache<tag-suffix>`
-    - e.g. `cache-gpu-nvidia-cuda-12-llama-cpp`, `cache-cpu-vllm`, `cache-nvidia-l4t-cuda-13-arm64-vllm`
-  - Root image builds (`image_build.yml`) buildkit cache: `cache-localai<tag-suffix>`
-    - e.g. `cache-localai-gpu-nvidia-cuda-12`, `cache-localai-gpu-vulkan`
-  - Layered base builds (`base_images.yml`) buildkit cache: `base-<stem>`
-    - e.g. `base-python-cpu-2404`, `base-cpp-cublas-2404-cuda13.0`
-  - Layered base **images** (the OCI manifests consumers FROM): `base-image-<stem>[-pr<N>]`
-    - e.g. `base-image-python-cpu-2404`, `base-image-cpp-cublas-2404-cuda13.0-pr9672`
-- The cache tags store multi-arch BuildKit cache manifests (`mode=max`); the `base-image-*` tags store ordinary OCI image manifests.
-
-## Read/write semantics
-
-| Trigger | `cache-from` | `cache-to` |
-|---|---|---|
-| `push` to `master` / tag | yes | yes (`mode=max,ignore-error=true`) |
-| `pull_request` | yes | **no** |
-
-PR builds read master's warm cache but never write — this prevents PRs from polluting the shared cache with their experimental state. After merge, the master build for that matrix entry refreshes the cache.
-
-`ignore-error=true` on the write side means a transient quay push failure does not fail the build; the next master push retries.
-
-## Self-warming, no separate populator
-
-There is no cron job that pre-warms the cache. The production builds *are* the populator. The first master build of a given matrix entry pays the cold cost; subsequent same-entry master builds reuse everything that hasn't changed (apt installs, gRPC compile in `Dockerfile.{llama-cpp,ik-llama-cpp,turboquant}`, Python wheel installs, etc.).
-
-Historically there was a `generate_grpc_cache.yaml` cron that targeted a `grpc` stage in the root Dockerfile. That stage was removed in July 2025 and the cron silently failed every night for 9 months without writing anything. It was deleted along with the registry-cache rollout.
-
-## The `DEPS_REFRESH` cache-buster (Python backends)
-
-Every Python backend goes through the shared `backend/Dockerfile.python`, which ends with:
-
-```dockerfile
-ARG DEPS_REFRESH=initial
-RUN cd /${BACKEND} && PORTABLE_PYTHON=true make
-```
-
-Most Python backends ship `requirements*.txt` files that **do not pin every transitive dep** (`torch`, `transformers`, `vllm`, `diffusers`, etc. are listed without a `==` pin, or with `>=` lower bounds only). With a warm BuildKit cache, the `make` layer hashes only on Dockerfile instructions + COPYed source — not on what `pip install` resolves at runtime. So a warm cache would ship the *first* version of `vllm` ever cached and never pick up upstream releases.
-
-`DEPS_REFRESH` defends against that:
-
-- `backend_build.yml` computes `date -u +%Y-W%V` (ISO week, e.g. `2026-W17`) before each build and passes it as a build-arg.
-- The `RUN ... make` layer's BuildKit hash now includes that string, so the layer invalidates **at most once per week**, automatically picking up newer wheels.
-- Within a week, builds stay warm.
-
-This applies only to `Dockerfile.python` because:
-- Go (`Dockerfile.golang`) pins versions in `go.mod` / `go.sum`.
-- Rust (`Dockerfile.rust`) pins via `Cargo.lock`.
-- C++ backends (`Dockerfile.{llama-cpp,ik-llama-cpp,turboquant}`) clone gRPC at a pinned tag (`v1.65.0`) and llama.cpp at a pinned commit; their inputs don't drift between rebuilds.
-
-### Adjusting the cadence
-
-If you need a faster refresh (e.g. while debugging an upstream flake), bump the format to daily (`+%Y-%m-%d`) or hourly (`+%Y-%m-%d-%H`). If you need a one-shot rebuild for a specific backend without changing the schedule, append a marker to the tag-suffix in the matrix or temporarily delete that backend's cache tag in quay.
-
-## Manually evicting cache
-
-To force a fully cold build for one backend or the whole image:
-
-```bash
-# Delete a single tag (requires quay credentials with admin on the repo)
-curl -X DELETE \
-  -H "Authorization: Bearer ${QUAY_TOKEN}" \
-  https://quay.io/api/v1/repository/go-skynet/ci-cache/tag/cache-gpu-nvidia-cuda-12-vllm
-
-# List all tags
-curl -s -H "Authorization: Bearer ${QUAY_TOKEN}" \
-  "https://quay.io/api/v1/repository/go-skynet/ci-cache/tag/?limit=100" | jq '.tags[].name'
-```
-
-Eviction is rarely needed in normal operation — `DEPS_REFRESH` handles weekly drift, source changes invalidate naturally, and `mode=max` keeps the cache scoped per matrix entry so a stale tag never bleeds into a different build.
-
-## What the cache **does not** cover
-
-- The "Free Disk Space" / "Release space from worker" steps run on every job — these reclaim ~6 GB on `ubuntu-latest` runners. They are runner-state cleanup, not Docker, and BuildKit caches don't apply.
-- Intermediate artifacts of `Build and push (PR)` are not pushed anywhere — PRs only build for verification.
-- Darwin builds (see below) — macOS runners have no Docker daemon, so the registry-backed BuildKit cache cannot apply.

-`backend_build_darwin.yml` runs natively on `macOS-14` GitHub-hosted runners — there is no Docker, no BuildKit, no cross-job registry cache. Instead, the reusable workflow uses `actions/cache@v4` for four native caches that mirror the spirit of the Linux cache (warm by default, weekly refresh for unpinned Python deps, PRs read-only).
-
-| Cache | Path(s) | Key | Scope |
-|---|---|---|---|
-| Go modules + build | `~/go/pkg/mod`, `~/Library/Caches/go-build` | `go.sum` (managed by `actions/setup-go@v5` `cache: true`) | All darwin jobs |
-| Homebrew | `~/Library/Caches/Homebrew/downloads`, selected `/opt/homebrew/Cellar/*` | hash of `backend_build_darwin.yml` | All darwin jobs |
-| ccache (llama.cpp CMake) | `~/Library/Caches/ccache` | pinned `LLAMA_VERSION` from `backend/cpp/llama-cpp/Makefile` | `inputs.backend == 'llama-cpp'` only |
-| Python wheels (uv + pip) | `~/Library/Caches/pip`, `~/Library/Caches/uv` | `inputs.backend` + ISO week (`+%Y-W%V`) + hash of that backend's `requirements*.txt` | `inputs.lang == 'python'` only |
-
-Read/write semantics match the BuildKit cache: `actions/cache/restore` runs every time, `actions/cache/save` is gated on `github.event_name != 'pull_request'`. PRs read master's warm cache but never write back.
-
-The Python wheel cache uses the same ISO-week cache-buster as the Linux `DEPS_REFRESH` build-arg — same problem (unpinned `torch`/`mlx`/`diffusers`/`transformers` resolve to fresh wheels weekly), same ~one-cold-rebuild-per-week solution.
-
-The brew Cellar cache requires `HOMEBREW_NO_AUTO_UPDATE=1` and `HOMEBREW_NO_INSTALL_CLEANUP=1` (set as job-level env). Without those, `brew install` would mutate the very directories that were just restored, defeating the cache.
-
-For ccache, the workflow exports `CMAKE_ARGS=… -DCMAKE_C_COMPILER_LAUNCHER=ccache -DCMAKE_CXX_COMPILER_LAUNCHER=ccache` via `$GITHUB_ENV` before running `make build-darwin-go-backend`. The Makefile in `backend/cpp/llama-cpp/` already forwards `CMAKE_ARGS` through to each variant build (`fallback`, `grpc`, `rpc-server`), so no script changes are needed. The three variants share most TUs, so ccache dedupes object files across them.
-
-### Cache budget on Darwin
-
-GitHub Actions caches are limited to 10 GB per repo. Steady-state worst case: ~800 MB Go cache + ~2 GB brew Cellar + up to 2 GB ccache + ~1.5 GB × 5 python backends. If the cap is hit, prefer collapsing the per-backend Python keys into a shared `pyenv-darwin-shared-<week>` key (accepts more cross-backend churn for a smaller footprint) before reducing other caches.
-
-## Layered base images (`ci-cache:base-image-*`)
-
-The registry-backed BuildKit cache deduplicates **within** a matrix entry's
-cache tag, but each matrix entry has its own tag — so the same `apt-get`,
-GPU SDK install, and language toolchain bootstrap runs into N different
-cache tags across the backend matrix. The layered base images factor that
-shared work out of the per-backend builds.
-
-They live in the same `quay.io/go-skynet/ci-cache` repo as the buildkit
-caches, under a distinct `base-image-` tag prefix so the OCI image
-manifests coexist with `base-<stem>` (the cache for building the base),
-`cache<tag-suffix>` (per-backend caches), and `cache-localai<tag-suffix>`
-(root image caches). Reusing `ci-cache` means no new quay repo or robot
-grant is needed — the same credentials that write the cache also write
-the image.

-
-The base image is **always** built before backends consume it, in the same
-workflow run. There is no cross-workflow dependency, no chicken-and-egg
-on first push, and no manual matrix to keep in sync — adding a backend
-matrix entry is just an edit to `.github/backend-matrix.yaml`.
-
-### Tag scheme
-
-`<stem>` is computed by `tagStem()` in `scripts/changed-backends.js` from
-the (lang, build-type, ubuntu, cuda, base-image) tuple. Arch is
-intentionally NOT in the stem — bases are built multi-arch when any
-consumer needs multi-arch, and single-arch otherwise (the `platforms`
-field on each base entry is the union of its consumers' platforms).
-
-| Build-type | Stem template |
-|---|---|
-| `''` (CPU) | `<lang>-cpu-<ubuntu>[-<base-image-slug>]` |
-| `cublas` / `l4t` | `<lang>-<build-type>-<ubuntu>-cuda<major>.<minor>[-<base-image-slug>]` |
-| anything else (vulkan, hipblas, intel, sycl_*) | `<lang>-<build-type>-<ubuntu>[-<base-image-slug>]` |
-
-The base-image slug is empty for the default `ubuntu:24.04` and a short
-parseable suffix otherwise (`jetpack-r36.4.0`, `rocm-7.2.1`,
-`oneapi-2025.3.2`, etc.).
-
-| Event | Pushed tag (in `quay.io/go-skynet/ci-cache`) |
-|---|---|
-| `push` (master/tag) | `:base-image-<stem>` |
-| `pull_request` | `:base-image-<stem>-pr<PR_NUMBER>` |
-
-The buildkit cache for the base build itself lives at
-`quay.io/go-skynet/ci-cache:base-<stem>` (`mode=max,ignore-error=true`),
-parallel to the per-matrix-entry caches. The `base-` (cache) and
-`base-image-` (image) prefixes never collide.
-
-The script also runs a collision check across consumers of each stem: if
-two consumers map to the same stem but disagree on `base-image` or
-`skip-drivers` (and skip-drivers is meaningful for that build-type), the
-script fails loudly. Resolve by encoding the differing input in
-`tagStem()` rather than letting the dedup silently pick a winner.
-
-### PR testability
-
-PRs run the same pipeline as master: derive bases → build bases (tagged
-`-pr<N>`) → run filtered backend matrix consuming those `-pr<N>` tags.
-End-to-end validation always lives within the PR.
-
-For PRs that only change `.docker/bases/Dockerfile.<lang>` (no backend
-source touched), `changed-backends.js` adds one canary backend matrix
-entry per (lang × build-type × arch × cuda × ubuntu) tuple to the filtered
-matrix so each base flavour gets exercised.
-
-### Existing language tiers
-
-| Tier (lang) | Recipe | Consumer Dockerfile(s) | Distinct stems |
-|---|---|---|---|
-| `python` | `.docker/bases/Dockerfile.python` | `backend/Dockerfile.python` | 9 |
-| `golang` | `.docker/bases/Dockerfile.golang` | `backend/Dockerfile.golang` | 8 |
-| `cpp` | `.docker/bases/Dockerfile.cpp` (apt + GPU + protoc + cmake + GRPC) | `backend/Dockerfile.{llama-cpp,ik-llama-cpp,turboquant}` | 8 |
-| `rust` | `.docker/bases/Dockerfile.rust` | `backend/Dockerfile.rust` | 1 |
-
-The C++ trio share a single `cpp` base because they only differ in their
-per-backend `make` targets. `langOf()` in `scripts/changed-backends.js`
-remaps `Dockerfile.{llama-cpp,ik-llama-cpp,turboquant}` → `cpp` so dedup
-works across the trio. If a future C++ consumer needs a *different* base
-(e.g. without GRPC, or with a different protoc version), give it its own
-`Dockerfile.<newlang>` recipe and remove it from the cpp remap.
-
-### Adding a new (accel × arch × cuda × lang) flavour
-
-Just add the matrix entry to `.github/backend-matrix.yaml` for the new
-flavour. The bases matrix and the per-entry `base-image-prebuilt` are
-derived automatically by `scripts/changed-backends.js`. Nothing else to
-change.
-
-### Adding a new language tier
-
-1. Create `.docker/bases/Dockerfile.<lang>` mirroring an existing tier
-   (apt + accel install + lang-specific toolchain).
-2. Slim `backend/Dockerfile.<lang>` to `FROM ${BASE_IMAGE_PREBUILT}` plus
-   the per-backend source COPY + build (no inline accel install).
-3. Add the new recipe to `baseTriggerFiles` in
-   `scripts/changed-backends.js` so PRs touching it fan out to canaries.
-4. Add `<lang>: (item) => item.dockerfile.endsWith("<lang>")` to
-   `langTriggerSelector` in the same file.
-5. Add a `LOCAL_BASE_<LANG>_TAG`, a `docker-build-<lang>-base` target,
-   and a clause in `local-base-tag` / `local-base-target` in `Makefile`.
-
-The `langsWithBase` set in `scripts/changed-backends.js` is auto-detected
-from the `.docker/bases/` directory at script startup, so step 1 alone is
-enough for the script to start emitting bases (and annotating matrix
-entries with `base-image-prebuilt`) for that lang. Steps 3–5 plug it
-into the canary fan-out and the local-build path.
-
-### Why not just rely on `mode=max` cache?
-
-`mode=max` deduplicates at the layer level, but each matrix entry has its
-own cache tag (`cache<tag-suffix>`). A change that invalidates the GPU SDK
-layer in one backend does not invalidate it in any other; each entry pays
-the full cost on its next rebuild. The shared base image is built once per
-(accel × arch × cuda × lang), then pulled by every backend that consumes
-it — that's the actual cross-matrix dedup.
-
-### Local builds
-
-All `backend/Dockerfile.{python,golang,cpp,rust}` consumers require
-`BASE_IMAGE_PREBUILT` (no inline fallback). The Makefile wires the right
-`docker-build-<lang>-base` as a prerequisite for each backend's
-`docker-build-<backend>` target, so:
-
-```bash
-# Build any backend; the matching base is built first if needed.
-make docker-build-vllm BUILD_TYPE=cublas CUDA_MAJOR_VERSION=12 CUDA_MINOR_VERSION=8
-make docker-build-llama-cpp BUILD_TYPE=cublas CUDA_MAJOR_VERSION=13 CUDA_MINOR_VERSION=0
-make docker-build-rerankers   # golang
-make docker-build-kokoros     # rust
-```
-
-Or build a base directly: `make docker-build-{python,golang,cpp,rust}-base
-BUILD_TYPE=...`. Or pull a pre-built one from quay if it exists for your
-target tuple.
-
-## Touching the cache pipeline
-
-When changing `image_build.yml`, `backend_build.yml`, or any of the `backend/Dockerfile.*` files:
-
-1. **Don't drop `DEPS_REFRESH=...` from the build-args** without a replacement strategy (lockfiles, pinned requirements). Otherwise master will silently freeze on whichever versions were cached at the time.
-2. **Keep `tag-suffix` unique per matrix entry** — it's the cache namespace. Two matrix entries sharing a tag-suffix would clobber each other's cache.
-3. **Keep `cache-to` gated on `github.event_name != 'pull_request'`** — PRs must not write.
-4. **Keep `ignore-error=true` on `cache-to`** — quay registry hiccups must not fail builds.
-5. **`tagStem()` in `scripts/changed-backends.js` is the single source of truth for base image tags.** The matrix entries are annotated with `base-image-prebuilt` in the same script run; backend-jobs reads the value as-is. There's no parallel YAML expression to keep in sync. Adding a new dimension to the stem (e.g. a slug for a new base-image variant) is a script change only.

-
-All Go tests — including backend tests — must use [Ginkgo](https://onsi.github.io/ginkgo/) (v2) with Gomega matchers, not the stdlib `testing` package with `t.Run` / `t.Errorf`. A test file should register a suite with `RegisterFailHandler(Fail)` in a `TestXxx(t *testing.T)` bootstrap and use `Describe`/`Context`/`It` blocks for the actual cases. Look at any existing `*_test.go` under `core/` or `pkg/` for a template.
-
-Do not mix styles within a package. If you are extending tests in a package that already uses Ginkgo, keep using Ginkgo. If you find stdlib-style Go tests in the tree, treat them as tech debt to be migrated rather than as a pattern to follow.
-
-This is enforced by `golangci-lint` via the `forbidigo` linter (see `.golangci.yml`); calls like `t.Errorf` / `t.Fatalf` / `t.Run` / `t.Skip` / `t.Logf` are flagged. Run `make lint` locally before submitting; the same check runs in CI (`.github/workflows/lint.yml`).

-# LocalAI Assistant — admin MCP server
-
-This document is the contract for **anyone** (human or AI agent) touching LocalAI's admin REST surface, the in-process MCP server that wraps it, or the embedded skill prompts that teach the assistant how to use it. Read this before adding/removing/renaming admin endpoints, MCP tools, or skill recipes.
-
-## What this feature is
-
-`pkg/mcp/localaitools/` is a public Go package that exposes LocalAI's admin/management surface as an MCP server. It is used in two ways:
-
-1. **In-process**: when an admin opens a chat with `metadata.localai_assistant=true`, the chat handler injects the in-memory MCP server (paired `net.Pipe()` transport, no HTTP loopback) so the LLM can install models, manage backends and edit configs by chatting.
-2. **Standalone**: the `local-ai mcp-server --target=…` subcommand serves the same MCP server over stdio, talking HTTP to a remote LocalAI instance.
-
-The two modes share **all** tool definitions and skill prompts. They differ only in their `LocalAIClient` implementation (`inproc/` calls services directly; `httpapi/` calls REST).
-
-## The three things you must keep in sync
-
-When you change LocalAI's admin surface, three layers must stay aligned:
-
-1. **REST endpoint** in `core/http/endpoints/localai/*.go`.
-2. **MCP tool registration** in `pkg/mcp/localaitools/tools_*.go`, plus a method on `LocalAIClient` (in `client.go`) and implementations in both `inproc/client.go` **and** `httpapi/client.go`.
-3. **Skill prompt** under `pkg/mcp/localaitools/prompts/skills/*.md` — the markdown that teaches the LLM how to use the new tool. If the new tool fits an existing recipe, update that recipe; otherwise add a new file.
-
-If you ship a REST endpoint without (2) and (3), conversational admins won't see the feature.
-
-## Checklist for adding a new admin endpoint
-
-- [ ] REST endpoint exists in `core/http/endpoints/localai/*.go` and is gated by `auth.RequireAdmin()` in `core/http/routes/localai.go`.
-- [ ] `LocalAIClient` interface in `pkg/mcp/localaitools/client.go` has a method covering the new operation.
-- [ ] DTOs added/updated in `pkg/mcp/localaitools/dto.go` (JSON-tagged; never expose raw service types).
-- [ ] `inproc/client.go` implements the new method by calling the service directly (not via HTTP loopback).
-- [ ] `httpapi/client.go` implements the new method by calling the REST endpoint.
-- [ ] Tool registration added in the appropriate `pkg/mcp/localaitools/tools_*.go`. Mutating tools must reference safety rule 1 in the description.
-- [ ] If the tool is mutating, ensure `Options{DisableMutating: true}` skips it (mirror the pattern in `tools_models.go`).
-- [ ] Skill prompt added or updated under `pkg/mcp/localaitools/prompts/skills/`. The prompt must instruct the LLM when to call the tool, what to ask the user first, and what to do on error.
-- [ ] Tests:
-   - `pkg/mcp/localaitools/server_test.go` adds the tool name to `expectedFullCatalog` and `expectedReadOnlyCatalog` (if read-only).
-   - Tool dispatch is added to `TestEachToolDispatchesToClient`.
-   - `pkg/mcp/localaitools/httpapi/client_test.go` covers the new HTTP path.
-
-## Adding a new skill recipe (no new tool)
-
-Sometimes you want to teach the LLM a new pattern that uses existing tools. Drop a markdown file under `pkg/mcp/localaitools/prompts/skills/<verb>_<noun>.md`. The file is automatically embedded by `//go:embed` and assembled into the system prompt in lexicographic order. No Go changes needed.
-
-Conventions:
-- Filename: `<verb>_<noun>.md` (e.g. `install_chat_model.md`, `upgrade_backend.md`).
-- First line: `# Skill: <Title Case description>`.
-- Number the steps. Reference exact tool names in backticks.
-- If the skill mutates state, remind the LLM to confirm with the user.
-
-## Code conventions
-
-These rules guard against the magic-literal drift that surfaced in the first audit. Do not re-introduce bare strings.
-
-- **Tool names** always come from the `Tool*` constants in `pkg/mcp/localaitools/tools.go`. Tool registrations, the test catalog (`server_test.go`'s `expectedFullCatalog` / `expectedReadOnlyCatalog`), and dispatch tables reference the constants. The embedded skill prompts under `prompts/` keep bare strings — that's the one allowed exception, and `TestPromptsContainSafetyAnchors` enforces alignment.
-- **Toggle/pin actions** use the `modeladmin.Action` type (`pkg/mcp/localaitools` and `core/services/modeladmin`). Use `ActionEnable`/`ActionDisable`/`ActionPin`/`ActionUnpin`; never bare `"enable"`/`"pin"` strings.
-- **Capability tags** for `list_installed_models` use the `localaitools.Capability` type (`capability.go`). The `LocalAIClient.ListInstalledModels` interface takes a typed `Capability`, and the `inproc` switch only accepts canonical values (`"embed"`/`"embedding"` are not aliases — only `CapabilityEmbeddings`).
-- **HTTP error checks** in `httpapi.Client` use `errors.Is(err, ErrHTTPNotFound)`, not substring matches on `err.Error()`. The typed `*HTTPError` carries `StatusCode` and `Body`; add new sentinel errors as needed rather than re-introducing string matching.
-- **Channel sends** to `GalleryService.ModelGalleryChannel` / `BackendGalleryChannel` from inproc clients MUST select on `ctx.Done()` so a cancelled chat completion releases the goroutine. See `inproc.sendModelOp` / `sendBackendOp`.
-- **Disk writes** of model config YAML go through `modeladmin.writeFileAtomic` (temp file + `os.Rename`). `os.WriteFile` truncates on crash and corrupts the model.
-- **MCP server lifecycle**: every initialised holder MUST register `Close()` with `signals.RegisterGracefulTerminationHandler`. The standalone `mcp-server` CLI uses `signal.NotifyContext` to honour SIGINT/SIGTERM.

-
-## Why two clients
-
-The in-process MCP server runs inside the same LocalAI binary that serves chat. Going over HTTP loopback would (a) require minting a synthetic admin API key for the server to authenticate against itself, (b) double-marshal every tool dispatch, and (c) lose access to in-process channels (e.g. `GalleryService.ModelGalleryChannel` for streaming install progress). So in-process uses `inproc.Client`. The standalone stdio CLI talks to a *remote* LocalAI; HTTP is the only option, so it uses `httpapi.Client`. Both implement the same `LocalAIClient` interface, and the parity test in `pkg/mcp/localaitools/parity_test.go` (when present) keeps their output equivalent.
-
-## Why prompt-enforced confirmation, not code gates
-
-The user chose KISS. Every mutating tool has a safety rule (`prompts/10_safety.md` rule 1) that requires the LLM to summarise the action and wait for explicit user confirmation before calling it. There is no `plan_*`/`apply_*` two-step in code. If you add a mutating tool, do **not** add per-tool confirmation logic in Go — instead, list the new tool name in `prompts/10_safety.md` so the LLM knows it falls under the confirmation rule.
-
-## Distributed mode
-
-The in-memory MCP server runs only on the head node (where the chat handler runs). `inproc.Client` wraps services that are already distributed-aware (`GalleryService` coordinates with workers; `ListNodes` reads the NATS-populated registry). No NATS routing of MCP tools — the admin surface lives on the head, period.

-name: 'Configure apt mirror'
-description: |
-  Reconfigure the GitHub Actions runner's Ubuntu apt sources to use an
-  alternate mirror, and emit the effective URLs as outputs so callers can
-  forward them as Docker build-args.
-
-  Two mirror profiles depending on where the runner lives, because the
-  best mirror differs by network:
-
-    * github-hosted runners run on Azure, so they default to the
-      Azure-hosted Ubuntu mirror (lowest latency, same VPC).
-    * self-hosted runners (arc-runner-set, bigger-runner, ...) typically
-      cannot route to azure.archive.ubuntu.com, so they default to the
-      kernel.org mirror, which is publicly reachable from anywhere.
-
-  Pass an empty string to either input to skip the rewrite for that
-  profile and keep upstream archive.ubuntu.com / ports.ubuntu.com.

-# Builds and pushes one (lang, accel, arch, ubuntu, cuda) base image flavour
-# to quay.io/go-skynet/ci-cache:base-image-<stem>[-pr<N>]. Consumed by
-# backend builds via the BASE_IMAGE_PREBUILT build-arg. PR builds tag with
-# `-pr${PR_NUMBER}` so the same PR's backend matrix can opt-in to the
-# freshly-built base; master builds overwrite the unsuffixed tag for
-# downstream consumption. The image lives in the same ci-cache repo as the
-# buildkit cache (under a `base-image-` prefix that doesn't collide with
-# the `base-<stem>` cache prefix), so no separate quay repo + grant is
-# needed. See .agents/ci-caching.md for the full tagging scheme.

-## Policy for AI-Assisted Contributions
-
-LocalAI follows the Linux kernel project's [guidelines for AI coding assistants](https://docs.kernel.org/process/coding-assistants.html). Before submitting AI-assisted code, read [.agents/ai-coding-assistants.md](.agents/ai-coding-assistants.md). Key rules:
-
-- **No `Signed-off-by` from AI.** Only the human submitter may sign off on the Developer Certificate of Origin.
-- **No `Co-Authored-By: <AI>` trailers.** The human contributor owns the change.
-- **Use an `Assisted-by:` trailer** to attribute AI involvement. Format: `Assisted-by: AGENT_NAME:MODEL_VERSION [TOOL1] [TOOL2]`.
-- **The human submitter is responsible** for reviewing, testing, and understanding every line of generated code.

 ## Quick Reference
 
@@ -36,7 +22,5 @@ LocalAI follows the Linux kernel project's [guidelines for AI coding assistants]
 - **Go style**: Prefer `any` over `interface{}`
 - **Comments**: Explain *why*, not *what*
 - **Docs**: Update `docs/content/` when adding features or changing config
-- **New API endpoints**: LocalAI advertises its capability surface in several independent places — swagger `@Tags`, `/api/instructions` registry, auth `RouteFeatureRegistry`, React UI `capabilities.js`, docs. Read [.agents/api-endpoints-and-auth.md](.agents/api-endpoints-and-auth.md) and follow its checklist — missing any surface means clients, admins, and the UI won't know the endpoint exists.
-- **Admin endpoints → MCP tool**: every admin endpoint that an admin would manage conversationally (install/list/edit/toggle/upgrade) MUST also be exposed as an MCP tool in `pkg/mcp/localaitools/`. The LocalAI Assistant chat modality and the standalone `local-ai mcp-server` consume that package; drift between REST and MCP is a real risk. Read [.agents/localai-assistant-mcp.md](.agents/localai-assistant-mcp.md) — the `TestToolHTTPRouteMappingComplete` test fails until you wire the new tool and update the route map.
 - **Build**: Inspect `Makefile` and `.github/workflows/` — ask the user before running long builds
 - **UI**: The active UI is the React app in `core/http/react-ui/`. The older Alpine.js/HTML UI in `core/http/static/` is pending deprecation — all new UI work goes in the React UI

-## AI Coding Assistants
-
-LocalAI follows the **same guidelines as the Linux kernel project** for AI-assisted contributions: <https://docs.kernel.org/process/coding-assistants.html>.
-
-The full policy for this repository lives in [`.agents/ai-coding-assistants.md`](.agents/ai-coding-assistants.md). Summary:
-
-- **AI agents MUST NOT add `Signed-off-by` tags.** Only humans can certify the Developer Certificate of Origin.
-- **AI agents MUST NOT add `Co-Authored-By` trailers** attributing themselves as co-authors.
-- **Attribute AI involvement with an `Assisted-by` trailer** in the commit message:
-
-  ```
-  Assisted-by: AGENT_NAME:MODEL_VERSION [TOOL1] [TOOL2]
-  ```
-
-  Example: `Assisted-by: Claude:claude-opus-4-7 golangci-lint`
-
-  Basic development tools (git, go, make, editors) should not be listed.
-- **The human submitter is responsible** for reviewing, testing, and fully understanding every line of AI-generated code — including verifying that any referenced APIs, flags, or file paths actually exist in the tree.
-- Contributions must remain compatible with LocalAI's **MIT License**.
-
 ## Testing
 
 All new features and bug fixes should include test coverage. The project uses [Ginkgo](https://onsi.github.io/ginkgo/) as its test framework.

-#      server-side random per-instance marker) with the legacy "<__media__>"
-#      literal. The fork branched before that PR, so server-common.cpp has no
-#      get_media_marker symbol. The fork's mtmd_default_marker() still returns
-#      "<__media__>", and Go-side tooling falls back to that sentinel when the
-#      backend does not expose media_marker, so substituting the literal keeps
-#      behavior identical on the turboquant path.
-#   3. Revert the `common_params_speculative` field references to the

-    Speaker (voice) recognition backend — the audio analog to
-    insightface. Wraps SpeechBrain ECAPA-TDNN (default engine, 192-d
-    embeddings, ~1.9% EER on VoxCeleb) plus an OnnxDirectEngine for
-    pre-exported WeSpeaker / 3D-Speaker ONNX models.
-
-    Exposes speaker verification (/v1/voice/verify), speaker embedding
-    (/v1/voice/embed), speaker analysis (/v1/voice/analyze), and 1:N
-    speaker identification (/v1/voice/{register,identify,forget}).
-    Registrations use LocalAI's built-in vector store — same in-memory
-    backing the face-recognition registry uses, separate instance.
