+# Progress Log
+
+## 2026-07-19
+
+- Item: F001
+- Summary: Created the isolated worktree, loaded product and design context, started three read-only audits, and confirmed the supported agent-init command starts the branch-scoped development server.
+- Files: `docs/agent-runs/directory-routes/feature-list.json`, `docs/agent-runs/directory-routes/progress.md`
+- Verification: `./scripts/agent-init.sh`
+- Blockers: none
+- Next: Finish source archaeology and implement the directory registry as a route-only input.
+
+- Item: F001-F005
+- Summary: Implemented versioned deterministic directory snapshots, route-only resolution, exact-address Join and permalink behavior, atomic subscription provenance, consented winner-change actions, per-slot automatic switching with safe undo, exact action-route redirects, localized disclosure/update UI, and the architecture decision record.
+- Files: `src/data/seedit-directories/`, `src/hooks/use-directory-list.ts`, `src/hooks/use-resolved-community-route.ts`, `src/lib/utils/directory-subscriptions.ts`, `src/lib/utils/directory-account-transforms.ts`, `src/components/directory-*`, `src/components/exact-community-action-route/`, `docs/architecture/directory-routes.md`
+- Verification: 25 test files / 168 tests; build, lint, type-check, Knip, AI workflow parity, generated LLM context, changed-scope React Doctor, translation coverage, and `git diff --check` pass.
+- Blockers: Full-repository React Doctor still exits on pre-existing findings outside this change; changed-scope React Doctor reports no issues.
+- Next: Finish the multi-engine desktop/mobile and throttled Chromium browser pass, then split the Seedit diff into focused commits without pushing it.
+
+- Item: F006
+- Summary: Completed the final quality gate and browser matrix. Directory aliases disclose and join the exact winner, exact-address routes remain exact, submit aliases canonicalize before rendering, and no directory slug enters account subscriptions.
+- Files: `docs/agent-runs/directory-routes/feature-list.json`, `docs/agent-runs/directory-routes/progress.md`
+- Verification: 25 test files / 168 tests; build, lint, type-check, Knip, AI workflow parity, changed-scope React Doctor, generated LLM context, and `git diff --check`; Chrome, Firefox, and WebKit at 1440x1000 and 390x844; Chromium mid-throttle warm navigation; light and dark themes; no horizontal overflow.
+- Blockers: Full-repository React Doctor retains pre-existing findings outside this change; external P2P router CORS/404/521 failures were observed during browser verification but produced no directory-feature exceptions.
+- Next: Review the four focused local commits; keep the Seedit branch unpushed until explicitly approved.

+# Seedit directory routes
+
+## Status
+
+Accepted.
+
+## Decision
+
+Seedit directory codes are mutable discovery routes, not subscription identities.
+
+- `/s/funny` resolves the finalized `funny` directory snapshot and displays its deterministic winner.
+- `/s/funny.bso` and `/s/funny-posting.bso` identify exact communities.
+- `account.subscriptions` contains only exact community addresses or public keys. A directory code is never stored there.
+- The home feed reads the exact subscription array directly and never resolves directory codes.
+- Joining from `/s/funny` atomically subscribes to the exact current winner and records Seedit-only directory provenance.
+- Generated post permalinks always use the post owner's exact community address and `/comments/<cid>`.
+- A winner change does not alter a subscription by default. Seedit presents an inline choice to switch, keep both, or keep the current community.
+- Automatic switching is an explicit per-directory preference. An automatic change produces a persistent notice with undo.
+
+The short route is therefore a contested front door. The user's feed and durable links remain pinned to identities they can inspect and carry to another Bitsocial client.
+
+## Snapshot rules
+
+Directory payloads use `schemaVersion: 1` and a monotonically increasing `revision`. The revision is the atomic change boundary: candidate membership or winner selection must not change at the same revision.
+
+Candidates are ordered deterministically by:
+
+1. score, descending;
+2. `addedAt`, ascending;
+3. exact address, ascending.
+
+Clients do not rotate to another candidate based on local availability. Every client using the same finalized snapshot must resolve the same winner.
+
+The current `bitsocialnet/lists` publication is a bootstrap transport for these snapshots. It does not define the eventual decentralized voting or finalization protocol.
+
+## Subscription provenance
+
+Seedit stores directory provenance separately from the portable exact subscription array. Each tracked slot records:
+
+- its exact attributable subscription address;
+- the last acknowledged winner address and revision;
+- whether the user explicitly enabled automatic switching.
+
+This metadata lets Seedit offer winner-change actions without inventing a second kind of subscription. Other Bitsocial clients can ignore it and still read the user's exact subscriptions correctly.
+
+## Defaults
+
+Seedit's default-subscription list remains a list of exact addresses. A default entry may also include `directoryCode` and `directoryRevision` to record which finalized directory snapshot selected it. New accounts receive exact subscriptions plus the matching Seedit provenance; existing accounts retain their exact choices until they act on an update or previously enabled automatic switching.
+
+## Rejected alternatives
+
+- Directory codes in `account.subscriptions`: this makes feeds change at read time and is not portable across clients.
+- Directory-coded post permalinks: a winner change can make an old post URL resolve through the wrong community.
+- Client-local offline failover: two clients could resolve the same short route to different communities.
+- Permanent Seedit-owned community subdomains: community identity should remain portable between Bitsocial clients.
+- Administrator allocation of short names: this recreates the centralized veto power the directory mechanism is meant to replace.
