refactor(b3-8): settings/audit family behind SettingsService (S-09, family 1) (#1477)

* feat(service): settings family — SettingsService over the Store seam

The B3-8 settings/audit family's service: List, Patch (whitelist,
boolean normalization, the require_2fa preconditions incl. the TOTP
census and the unrelated-key guard, atomic apply, one audit row per
changed key) and Setting (the read the hub and the backup scheduler
consume; wraps db.ErrNotFound as the store reports it). db gains
ApplySettings — the handler's raw upsert loop as one hand-written
transactional wrapper where raw SQL belongs — and Store carries it.

parseSettingsPatchBool duplicates auth.go's parseBooleanSettingValue
with the admin surface's own pinned error wording; both messages are
test-pinned, so the twins stay separate.

Service-level characterization in settings_test.go mirrors the
admin/api_test.go PATCH rows and adds the service-only contracts
(ErrNotFound wrap, audit rows, multi-key apply).

* refactor(admin): settings handlers thin over SettingsService; scheduler reads via it

handleGetSettings/handlePatchSettings become adapters (decode, delegate,
map ErrBadRequest to 400 with the service's prefix-free message); the
whitelist and every precondition now live only in the service, so
admin/types.go's copy is gone. MaintainBackups reads backup_schedule and
backup_retention through the service — its backup mechanics keep the
handle — and the maintenance chain threads Settings from the runtime the
hub stage built. NewHandler/NewAdminAPI gain the settings parameter;
all 207 construction sites wired via the newTestSettingsService helper.

Behavior parity pinned by the existing TestAdminAPI_*Settings* rows
(all green); the only unpinned change is the PATCH 500 path collapsing
its four stage-specific internal messages into one.

* refactor(ws): hub settings cache reads through a SettingsReader

The hub's server_name/motd cache consumes a consumer-side SettingsReader
interface (service.SettingsService satisfies it; HubOptions.Settings is
required and validated like DB and Limiter — the RequiredCollaborators
pin gains the refusal case). hub_settings.go no longer touches db at
all, so the import pin from the B3-5 finisher goes, and its allowlist
row goes with it; the thinned admin settings handler's row is deleted
too — two allowlist rows down, the settings family's persistence now
lives only in db/ and service/.

Test helpers (both ws package namespaces) default the reader over the
test database; newBareHub wires it explicitly; production passes
Services.Settings from StartRuntime.

* docs(boundaries,b3): settings/audit family re-measure and evidence

The backup pair takes its forecast boundary disposition; the family's
two deleted rows and the disposition counts (28/18/15 -> 24/18/17)
re-derived from the tool. Family evidence block appended to the B3-8
section; README B3 row records B3-5 complete and the family opened.

* fix(service): prefix-free ErrBadRequest wraps for the pinned admin bodies

The %.0w rework was meant to ride the service commit but was left
unstaged: with the plain %w wrap the PATCH error bodies carry a
'bad request: ' prefix the admin pins reject. Zero-width wrapping keeps
errors.Is(ErrBadRequest) while err.Error() stays exactly the pinned
message.

* test(app): lifecycle hub fixtures wire the required Settings reader

The two direct ws.NewHub sites in lifecycle_test predate Settings
becoming required; race across internal/app is green again.

* test(db): cover ApplySettings — the db coverage floor caught the gap

CI's coverage floor failed db at 78.9% against 79.3%: ApplySettings was
exercised only from service tests, which do not count toward db's own
figure. Four db-side rows cover the apply, the empty no-op, the
in-transaction failure rollback and the begin failure, using the
package's full-migration opener.

* chore(coverage): raise the service floor to the branch's measured 69.2

The settings family's tested service code raised the Linux figure from
the 67.8 floor to 69.2; the ratchet raises the floor in the same PR
(service is not in the run-varying set). db stays at 79.3 — this PR
restores its figure (79.5 with the ApplySettings tests), it did not set
out to raise it.

+description: Run a bug hunt and turn its findings into committed fixes. Use when starting a hunt, resuming one, or fixing findings already in the ledger. Covers the ledger handoff between the bughunt and bughunt-fix workflows.
+---
+
+# Running the bughunt pipeline
+
+Two workflows with a human gate between them. The ledger at
+`.superpowers/findings-ledger.json` is the interface. Both workflows are pure
+functions of their `args` — **the session does all file I/O**, because workflow
+scripts have no filesystem access.
+
+`.superpowers/` is gitignored. This repo is public and unfixed defects must never
+reach a commit, an issue, or a PR body.
+
+## 1. Hunt
+
+**Launch the hunt from a turn that carries a token-budget directive** (recommended:
+`+25M`, comfortably above a full coverage run's ~8-12M). The workflow's cost ceiling is gated
+on `budget.total`, which is null without a directive — a directive-less run has **no
+ceiling at all**. The workflow's first log line echoes the state: `budget=25M` means
+armed; `budget=NONE - cost ceiling disarmed` means stop the run and relaunch with a
+directive.
+
+Before launching, in order:
+
+1. **Build the inventory**: `node .superpowers/rank-explore.mjs` — writes
+   `.superpowers/explore-ranking.json`: EVERY non-test source file (~419 rows), each with
+   `examined` (already carries a ledger finding or a LIVE explored-clean record → the hunt
+   pre-seeds its covered set), `risky` (top coupling ∪ past-bug clusters ∪ top churn,
+   capped at 40 → they get an extra pass through all 5 bug-class lenses), and `churn`.
+   Explored-clean records carry content hashes: editing a file expires its clean record,
+   so re-runs automatically re-hunt what changed. The hunt cannot stop while any inventory
+   file is uncovered, so a full run now takes ~10-20 rounds and ~8-12M tokens — the `+25M`
+   directive still covers it. Regenerate the inventory and read `known` from the ledger in
+   the SAME session step: both derive from `findings-ledger.json`, and every `known` file
+   must be `examined` in the inventory — a `known` file the inventory does not mark
+   examined can never be drawn (the seen-filter blocks it) nor covered, which would
+   strand `uncoveredCount()` above zero and block convergence.
+2. Read the ledger and pass every record in as `known`, so the hunt does not
+   re-derive anything already found, fixed, declined, or refuted.
+
+```
+Workflow({
+  name: "bughunt",
+  args: {
+    known: <every record from findings-ledger.json, as {file, line, title, status}>,
+    graph: <the rows of .superpowers/explore-ranking.json>,
+    lenses: [ {key, prompt}, ... ],   // optional: scope the hunt to one subsystem
+    maxRounds: 30,   // safety backstop only - coverage + dry is the real stop
+    dryThreshold: 2,
+  },
+})
+```
+
+If `graph` is omitted or empty the hunt logs
+`explore: args.graph absent/empty - falling back to churn-based fresh eyes` and
+still runs — degraded targeting, never a smaller lens family.
+
+`converged: true` now means: every inventory file was covered by a completed
+explicit-file lens (or carries a verdict), the risky class sweep ran, and then
+`dryThreshold` consecutive eligible rounds confirmed nothing (a round where the
+lens family comes up empty with the pool drained counts as dry — family
+`exhausted`). Rows without the `examined` field fall back to the old
+quietness-only stop. Two new run outcomes: `stalledCoverage: true` means adaptive
+rounds stopped shrinking the uncovered pool (usually mass finder failures —
+investigate before re-running); a budget stop now reports
+`coverage.uncoveredAtStop` so the next run knows exactly what remains (re-run
+with the ledger as `known`; live explored-clean records pre-cover what was
+finished, so the sweep naturally continues where it stopped).
+
+Omit `lenses` for a general hunt across the rotating families.
+
+**Scoping a hunt while coverage mode is armed is a budget trap:** `lenses` only
+replaces round 1, and inventory rows with `examined` force the coverage stop
+rule — from round 2 the run sweeps the ENTIRE uncovered pool and the risky
+sweep before it may converge, at general-hunt cost. For a true scoped hunt,
+pass a subsystem-filtered inventory as `graph` (only the rows you want swept),
+or rows without the `examined` field to fall back to the legacy quietness-only
+stop.
+
+Each lens object is `{key, prompt}`. `key` must match `^[a-z0-9-]+$` —
+lowercase letters, digits, and hyphens only. Keys get interpolated into agent
+labels of the form `r<N>:hunt:<key>:<model>`, and a key containing uppercase,
+dots, or spaces breaks label parsing. A lens missing `key` or `prompt` is not
+validated — it reaches the finder prompt as the literal string `undefined`,
+silently degrading that lens instead of failing loudly. Check your lens
+objects before passing them.
+
+When it returns, first save the raw result verbatim to
+`.superpowers/hunts/<YYYY-MM-DD>-raw.json`, then:
+
+```bash
+node .superpowers/render-run-stats.mjs .superpowers/hunts/<YYYY-MM-DD>-raw.json <hunt-name>
+```
+
+This validates the result shape, appends the run's telemetry to
+`.superpowers/run-history.json`, updates `.superpowers/explored-clean.json`, and
+checks **every** confirmed finding's coordinates against the working tree (file
+exists, line within length — the report agent that used to spot-check two findings
+is gone). Resolve any `COORD` warnings before appending to the ledger: stale
+coordinates poison `bughunt-fix`.
+
+Then append each entry of `result.confirmed` to the ledger with
+`status: "open"`, an id from `nextId`, and today's date. Bump `nextId`. The
+incoming record carries a prose `fix` field (bughunt's suggested remedy) —
+rename it to `suggestedFix` when appending, so the ledger's `fix` field starts
+as `null` and is free for `bughunt-fix` to fill in with `{commit, test,
+revertProof}` once something is actually fixed. Then:
+
+```bash
+node .superpowers/render-ledger.mjs
+```
+
+Each confirmed record carries `finder: "opus"`. The dual-model finder panel was
+retired 2026-08-12: attribution over the only measured run priced sonnet's unique
+yield (1 high, 4 medium, 9 low) at roughly a third of the run's agents. The known
+cost: with one finder, a lazy-but-non-null finder round can read as "clean" where
+the panel required both models to agree it was. Watch `runStats` — per-lens
+candidate counts make an anomalously empty lens visible after the fact.
+
+## 2. Gate (human)
+
+Generate the readable rendering, then read it — it is gitignored, so a fresh
+clone has no copy until you make one:
+
+```bash
+node .superpowers/render-ledger.mjs   # writes .superpowers/FINDINGS.md
+```
+
+Mark anything you do not want fixed as `declined` with a rationale — declined
+findings are fed back into the next hunt's prompts and never re-reported. Edit
+`findings-ledger.json` to do that, not the rendering.
+
+## 3. Fix
+
+```
+Workflow({
+  name: "bughunt-fix",
+  args: {
+    findings: <records with status "open" from findings-ledger.json>,
+    branch: "fix/bughunt-YYYY-MM-DD",
+    only: ["OC-0042"],        // optional
+    maxSeverity: "medium",    // optional
+    circuitBreaker: { threshold: 0.5, minAttempts: 3 },  // optional; false to disable
+  },
+})
+```
+
+Create and check out the branch first — the workflow commits to whatever branch
+is current and does not create one.
+
+### Composing the batch
+
+The workflow clusters findings by the file the BUG is in, but its same-run
+overlap guard fires on the files the FIX touches. Compose the batch so the two
+can never disagree:
+
+- **Close over the file relation.** Pull in every open finding that shares a
+  file with anything already selected, regardless of severity — a same-file
+  finding left behind is a future cross-cluster block.
+- **Re-check coordinates against the working tree** (file exists, line within
+  length) before launching. render-run-stats checked them at hunt time only;
+  merges since then can stale them.
+- **Scan fix-touchpoints, then read only the hits.** Token-scan each finding's
+  `suggestedFix`/`why` for path-like tokens owned by another cluster, then read
+  just the flagged records to separate evidence citations from actual fix
+  edits — the scan over-predicts (a measured run: 6 flagged, 1 real). True
+  collisions go into **sequential waves**: launch the later wave after the
+  earlier wave's commits land, and the same-run guard never fires. Batch 4
+  skipped this and self-blocked 20/27 findings; batch 6 ran it and blocked
+  zero.
+
+### Security findings
+
+Fixed security findings ship in normal PRs at this project's stage (alpha,
+~zero external deployments): the fix and its disclosure land atomically.
+Commit subjects and PR text describe the fix, never the exploit — no
+severity labels, repro steps, or attack narratives in public text — and a
+release should follow soon after merge. The GHSA advisory route is reserved
+for coordinated disclosure once there is a real deployed user base. Never
+decline a finding merely for routing.
+
+## When a run trips the breaker
+
+The run stops early if more than `threshold` of attempted findings fail, once at
+least `minAttempts` have been tried. `declined` never counts as a failure — a run
+where several findings are correctly declined is a good run. There are two trip
+points: the fix stage (before any prove agent runs) and inside the prove loop.
+
+**A tripped run means stop and investigate, do not re-run.** The usual causes are
+being on the wrong branch, a broken test runner, or ledger coordinates gone stale
+after a rebase. Re-running without fixing the cause just spends the budget again.
+
+**Re-verify a blocked finding against HEAD before fixing it.** A deferred item
+ages against a moving codebase: later hunts routinely fix a blocked finding as a
+side effect of an overlapping sibling, and a saved debris patch stops applying
+once a refactor rewrites the files it touched. Check the _mechanism_ still exists
+at HEAD, not just the line coordinates. If it is already covered, mark it fixed
+with a pointer to the covering commit instead of re-fixing it. Of 6 findings
+blocked on 2026-08-14, 2 were already fixed 5 days later and the debris patch no
+longer applied at all.
+
+Findings from clusters the run never reached come back `blocked` with a rationale
+naming the breaker. Set those back to `open` once the underlying problem is fixed
+— they were never attempted. Their edits are sitting uncommitted in the working
+tree, so the debris warning above applies to them too.
+
+Whatever committed before the trip still goes through the gate, so `result.gate`
+tells you whether those commits are green.
+
+When it returns, for each entry in `result.results`:
+
+- `fixed` → status `fixed`, `fix: {commit, test, revertProof: "self-reported"}`
+  using the matching `result.commits` entry — the prove agent's own report, not
+  yet independently checked (see step 4)
+- `declined` → status `declined`, copy the rationale
+- `blocked` → status `blocked` (not `open`), record the rationale; these failed
+  their revert-proof, tripped the cross-cluster overlap guard, or their agent
+  died, and want a human. Do NOT leave them `open` — `bughunt-fix` only picks up
+  `open` findings, so `open` would silently re-enter one of these into the next
+  fix run, exactly the retry loop the design deliberately excludes ("one human
+  look beats three agent attempts").
+
+Ledger writes select records by id or `fix.commit` — never by date fields,
+which collide when two batches reconcile on the same day — and every bulk
+mutation asserts its expected match count before writing (a same-day sibling
+batch once inflated a 29-record update to 44 matches; only the count
+assertion caught it).
+
+Check `result.gate`. A failed gate leaves the commits in place on the branch —
+fix it yourself, do not re-run the workflow over it.
+
+A fix that tightens a guard and fails ONLY e2e/CI while unit tests and local
+gates stay green is usually a test-infrastructure defect, not a bad fix:
+triage the mock/harness first. Check that mock echoes carry the same fields
+the real server sends (real channel ids, not sentinels), and never assert
+broadcast delivery on a socket the same operation force-closes. Mocks
+calibrated against lenient code silently decay into lies — every
+guard-tightening fix is also a fidelity audit of the mocks that exercise it.
+The Playwright trace's console stream (grep the .trace file for the app's log
+lines) locates the mechanism in minutes.
+
+## 4. Verify the fixes independently — REQUIRED
+
+The workflow's prove agent _self-reports_ that each test went RED with the fix
+reverted. Nothing inside the workflow can verify that: workflow scripts have no
+filesystem access. You do. Run the independent proof over every commit the
+workflow made:
+
+```bash
+node .superpowers/verify-fixes.mjs <sha> <sha> ...
+```
+
+It reverse-applies each commit's own source diff onto the current tree, runs
+that commit's tests, and requires them to FAIL — then restores to HEAD and
+requires them to PASS. This is the only check in the pipeline no agent can
+fabricate. The reverse-apply/restore-to-HEAD shape is load-bearing for
+**stacked waves**: sequential waves pile commits onto shared files, and an
+older per-commit-snapshot restore silently corrupts every later verification
+(a mid-branch snapshot left in the tree once made a whole package
+uncompilable for five subsequent runs). Rust commits with in-file
+`#[cfg(test)]` tests fail the file-level source/test split entirely — prove
+those by hand at hunk level, splitting at the `mod tests` boundary.
+
+While it runs it checkouts and restores source files, so the working tree is
+not a stable read surface: anything reading concurrently — review agents,
+scanners, hooks — must read committed objects (`git show HEAD:<path>`) or
+pre-taken snapshots, and any live-tree scanner finding from that window needs
+re-verification against HEAD before it is believed.
+
+Any `FAIL ... VACUOUS TEST` means the fix was committed behind a test that
+proves nothing. Revert that commit and set its findings back to `open`; do not
+talk yourself into keeping it because the code change looks right.
+
+Two classes are exempt from the insta-revert, both artifacts of the verifier
+choosing the wrong detector rather than of a vacuous test:
+
+- **Race/deadlock-class fixes** whose test only fails under its detector.
+  verify-fixes escalates to `-race` before declaring vacuity; if an older copy
+  reports VACUOUS on such a fix, re-prove red/green by hand under the class's
+  detector (`go test -race ./<pkg>/`) before reverting anything.
+- **Cross-stack commits** whose test files belong to a different stack than
+  their source files (e.g. a vitest file pinning a `src-tauri/` config). The
+  script now keys the runner off the TEST files; an older copy keyed it off
+  the sources and ran the wrong stack's suite, which never executes the proof.
+  On any VACUOUS verdict for a cross-stack commit, re-prove by hand with the
+  test file's own runner before reverting.
+
+For every commit `verify-fixes.mjs` reports `PASS`, upgrade that commit's
+findings' `fix.revertProof` from `"self-reported"` to `"pass"` — this
+independent run is the only check in the pipeline no agent can fabricate, and
+it is what earns the upgrade. A `FAIL` commit needs no further edit here — it
+was already reverted and its findings set back to `open` above.
+
+Re-render. Before you review the branch and open the PR, inspect the working
+tree: a blocked or declined cluster can leave its edits and any new failing
+test it wrote sitting uncommitted. The gate's "N uncommitted modifications at
+gate time" note is the trigger list. **Classify before discarding** — an
+uncommitted modification to a TRACKED test file may be a required companion to
+a committed fix, not debris. Two known mechanisms: the old test locked the old
+buggy behavior, and the fix widened an interface that a fake/mock in a test
+file the cluster never named must now implement (without it the committed
+package does not even compile). The decisive test: `git stash push -- <file>`,
+then compile/test the committed state alone — if it fails, the modification is
+a companion; fold it into the causing commit (fixup + autosquash keeps the
+history coherent for verify-fixes) or commit it with attribution. Only then
+discard true debris — a reflexive `git add -A` would commit tests that
+describe unfixed defects into a public repo.
+
+**Capture before destroying, as separate verified steps.** Preserve blocked or
+declined edits by copying the files aside (or `git stash push -u` after
+confirming it actually saved something) BEFORE any rm/checkout, and never
+chain the capture and the destructive step into one command — a capture
+failure then becomes data loss (`git diff /dev/null <file>` fails outright on
+Windows git and has deleted debris before it was saved). Never blind
+`git stash pop`: a paired push on a clean tree saves nothing, and the pop then
+grabs whatever foreign stash sits on top (a preserved debris stash, in the
+measured case — ~40 conflicted paths). Pop only a ref you verified your own
+push created; for temporary file comparisons, skip stash entirely and read old
+versions from the object store (`git show <ref>:<path>`). Audit what got COMMITTED, too: parallel fix agents share the tree, so a
+prove agent can commit a sibling cluster's content that happened to sit in a
+shared test file or in regenerated output. Grep the committed tests for
+finding ids outside the run's fixed set, and re-run the generated-code
+verifies (sqlc/protocol) after the debris discard — a mismatch means a commit
+carries foreign regen content. Anything pinning or describing an UNFIXED
+finding must be excised from history (amend + rebase onto the amended
+commit), not merely removed by a follow-up commit.
+
+Then review the branch against the merge-base — `git diff
+origin/dev...HEAD` (three-dot), never two-dot: a concurrent merge plus a
+background fetch can move the base mid-run and turn the two-dot diff into
+phantom deletions. `dev` is the integration branch every PR targets
+(docs/contributing.md#branch-and-pr-model); use `origin/main` only for a
+release PR cut from `dev`. If origin moved, confirm zero file overlap and a
+clean `git merge-tree --write-tree origin/dev HEAD` before opening the PR by
+hand. The workflow never
+pushes and never opens a PR.

+Which is `scripts/check-doc-counts.mjs` plus, since B1-6, an actual render of
+the findings ledger:
+
+```bash
+node .superpowers/render-ledger.mjs
+```
+
+`.superpowers/FINDINGS.md` is **not tracked** — it is generated on demand and
+gitignored, so there is no committed rendering to go stale. The gate is that
+generation succeeds. Rendering subsumes `--check`: the renderer validates and
+exits 1 before it writes, so a schema break (including an unranked `severity`)
+fails here.
+
+CI does one thing more, in `Docs & Ledger Consistency` — it renders **twice**
+and compares, proving the output is a pure function of the ledger, then uploads
+the rendering as the `findings-ledger-rendering` artifact so a reviewer can read
+it without running Node.
+
+## Hygiene (from the repository root)
+
+```bash
+npm run check:hygiene
+```
+
+Which is:
+
+```bash
+npx prettier --check .          # every material tracked source, not just client TS
+shellcheck <tracked *.sh + .githooks/pre-commit + .githooks/pre-push>
+actionlint .github/workflows/*.yml
+```
+
+`shellcheck` and `actionlint` have no clean Windows install, so `run.mjs` marks
+them optional and prints `--- SKIP` instead of failing; CI runs them for real.
+Prettier is not optional and runs everywhere.
+
+The file lists come from `git ls-files`, never a filesystem glob:
+`.claude/worktrees/` holds gitignored copies of the tree that a glob would
+happily lint.
+
+Go formatting is not here. `gofmt -l` prints offenders and still exits 0, so it
+cannot fail a build; the `formatters` block in `Server/.golangci.yml` enforces
+it inside `golangci-lint run`, and `.githooks/pre-commit` catches staged files.
+
+## Rust (from `Client/src-tauri/`)
+

+cargo fmt --all -- --check               # runs ahead of clippy in CI

+cargo clippy --all-targets -- -D warnings
+cargo install cargo-audit@0.22.1 --quiet && cargo audit   # CI runs this in tauri-build
+```
+
+`cargo audit` is the one gate here that turns red with **zero** local changes —
+an advisory published upstream breaks a branch that was clean yesterday. Check the
+advisory date before hunting your diff. It is skipped on Dependabot PRs by design
+(it overlaps the scanning that opened them), so a clean Dependabot run does not
+mean the advisory set is clean. The client equivalents, `npm audit --omit=dev
+--audit-level=high` and `knip`, are advisory in CI.
+
 `fallback_crypto` is `cfg(not(windows))`, so its tests compile to nothing on a
 Windows box and only run on the Linux/macOS runners.
 
 Do not attempt `npm run tauri build` locally — the full desktop build runs in
 CI on PRs to `main` and pulls heavy system dependencies.
 
+## Reading a red check
+
+**Causality before forensics.** Before opening a failing job's log, diff the
+PR's changed-file set against that job's input surface and ask whether the change
+could reach it. A diff touching only `.github/workflows/*.yml` cannot cause a Go
+goroutine leak — that failure is pre-existing or flaky by construction. Re-run
+first, and check `dev`/`main` is green to tell "flaky" from "already red". Only
+start log-reading once the change plausibly reaches the job.
+
+**Compare against the baseline, never against zero.** For any gate a repo
+knowingly runs red, the unit of verification is the _delta_ from a recorded
+baseline, not pass/fail — absolute pass/fail only means something when the
+intended state is zero. Get the delta with `git stash && <gate> > /tmp/base &&
+git stash pop && <gate> | diff /tmp/base -`. This repo currently carries **no**
+known-red gate: `golangci-lint`'s complexity backlog was cleared to zero, so a
+red `golangci-lint` is now genuinely yours. If a budget is ever retuned upward,
+record the new baseline here next to the command or the gate reports nothing.
+
+**A dependency bump that breaks the build may be a fork, not a version.** When an
+updated dependency suddenly demands configuration it never needed, suspect it was
+inheriting that configuration from a shared resolution with another dependent.
+Diff the lockfile _entry count_ for that dependency between base and PR: a 1 → 2
+transition means the update forked it into two semver-incompatible copies, feature
+unification stopped crossing the boundary, and the fix is to restore version
+alignment with whatever else requires it — not to set the feature the new copy
+asks for.

+Skills improve best from friction noticed during real work, not from sitting

+`[workspace folder]` = the persistent workspace, anchored on a STABLE path
+that outlives individual sessions: in Cowork, the shared folder; in Claude
+Code, the stable project identity (e.g.
+`~/.claude/projects/<project-id>/`), NOT the current working directory. A
+cwd inside an ephemeral checkout — a git worktree under
+`.claude/worktrees/`, a temporary clone — is torn down with the checkout
+and takes the observation log with it. The observation log lives at
+`[workspace folder]/skill-observations/log.md` unless the user's
+configuration pins it elsewhere.
+
+## Reference files — load on demand, not up front
+
+- `references/weekly-review.md` — the comprehensive review procedure
+  (scheduled or 7-day fallback), approval policy, delivery/staging of
+  updated skills. Load when a review triggers or the user asks for one.
+- `references/skill-authoring.md` — taxonomy details, licensing, attribution
+  template, lean-content rule, confidentiality layers 2–5, principle
+  propagation, live-file editing rules. Load before creating or editing any
+  skill.
+- `references/environments.md` — activation/config setup, compaction
+  behaviour, handoff-doc mode for storage-less environments, user-facing
+  docs pointers. Load for setup questions or when there's no filesystem.
+
+These loads are mandatory steps, not suggestions: when an episode fires
+(review triggers → weekly-review; creating/editing a skill →
+skill-authoring; setup/no-filesystem → environments), load the file before
+proceeding — never improvise the episode from this core file. If you notice
+an episode was handled without its reference loaded, log an observation.
+
+**Bundle manifest:** this skill consists of `SKILL.md` plus the three
+reference files listed above. If a referenced file is missing, the install
+is incomplete: proceed using the rules in this file, tell the user which
+files are missing, and point them to the full bundle at the canonical
+source (for the published version, the repository in the attribution
+above).
+
+## Session Start Protocol
+
+1. If `skill-observations/log.md` or `cross-cutting-principles.md` don't
+   exist, create them (templates below / in the principles section of
+   `references/skill-authoring.md`). Also create
+   `skill-observations/last-review-date.txt` containing the literal value
+   `never` if it doesn't exist — never write a date into it at setup; a
+   date means a review actually ran. Before creating or writing anything:
+   if the resolved workspace folder sits under an ephemeral path (e.g.
+   `.claude/worktrees/`, a temporary clone), warn the user and re-anchor
+   on the stable project path first — state written to an ephemeral
+   checkout is lost at teardown.
+2. Scan OPEN observations and active principles; hold them in awareness,
+   don't surface unprompted.
+3. Read `skill-observations/last-review-date.txt`. The value carries the
+   truth: a date = when the last review actually ran; `never` = no review
+   has run yet. A missing file is abnormal (step 1 creates it) — recreate
+   it with `never`, don't invent a date. If the value is `never` or older
+   than 7 days AND there are OPEN observations: in an interactive session,
+   offer the review in one line ("the observation backlog hasn't been
+   reviewed [in N days / yet] — run it now, or carry on with your task?")
+   and proceed with the user's task unless they opt in; never gate their
+   work on the review. Only a scheduled/autonomous run loads
+   `references/weekly-review.md` and runs the review unprompted.
+4. Once per session: if no CLAUDE.md (or equivalent) activation instruction
+   for this skill exists, briefly suggest adding one (see
+   `references/environments.md`). Skip if already configured.
+5. Note the log's modification time. If modified in the last few hours,
+   another session may be writing to it — re-read immediately before every
+   append, never trust a remembered "current number".
+
+## When to Observe
+
+Active for the entire task session: execution, post-task feedback and
+review discussion, meta-discussion about skills or methodology, and
+reflective/strategy conversations about how work should be done. **The
+observation mindset does not deactivate when the conversation shifts from
+doing the work to discussing it** — user feedback in review phases is often
+the highest-signal input. Inactive only for casual conversation and quick
+factual questions with no tools or deliverables involved.
+
+## What to Watch For
+
+**Signals for a NEW skill:** a reusable multi-step workflow; a methodology
+the user explains that no existing skill captures; a recurring task type
+with similar structure; a process with clear inputs, phases, outputs; the
+user describing a refined process ("I always do it this way"); a structured
+approach emerging naturally during work.
+
+**Signals for IMPROVING an existing skill:** anything from a task that used
+a skill and could make it better — problems, positive signals, or neutral
+gaps. Examples: the agent violates a documented rule (the skill needs
+enforcement, not louder rules); a user correction reveals a missing rule or
+edge case; a better workflow emerges than the skill recommends; a technique
+works well enough to promote from incidental to recommended; an undocumented
+use case; feedback that generalises; a wrong assumption; new tooling
+obsoletes a step; corrections forming a pattern; a principle that applies to
+other skills too; a naming/framing/structural suggestion, even
+conversational.
+
+**Signals for SIMPLIFYING a skill:** a section never relevant across many
+sessions; a rule from a single unvalidated observation; workflows users
+consistently shortcut; sections loaded but never acted on; contradictory
+rules; "just in case" complexity that never triggered; a rule the agent
+consistently fails to follow (convert to structural enforcement — checklist,
+verification step, unskippable tool call — or remove it). Treat these as a
+review checklist; ask "what can we remove?" as deliberately as "what should
+we add?"
+
+**Do NOT log:** one-off corrections that don't generalise; preferences
+already captured in a skill; tool bugs unrelated to methodology;
+observations that would need proprietary client information to be useful in
+an open-source skill (unless an internal skill is the right home).
+
+## How to Log
+
+Append to the log **silently, within the same turn or the next** — never
+batch mentally for later; the act of writing is the enforcement mechanism.
+
+**Mandatory observation checkpoint after every 3rd TodoWrite completion:** After
+marking the 3rd, 6th, 9th (etc.) TodoWrite item as completed in a session, you
+must **write to the log** — not merely pause to ask yourself a question. Either
+append any pending observations, or, if genuinely none have accumulated, append
+an explicit acknowledgement marker (a one-line `no observations` note for that
+checkpoint). The required action is a concrete log write; a remembered "ask
+whether" is not enforcement. This is a hard checkpoint, not a suggestion — the
+skill has demonstrated that softer "check when completing items" or "pause and
+ask" guidance gets lost during cognitively demanding analytical work, exactly
+when the most observations accumulate. The count doesn't need to be precise;
+the rule is: roughly every third completion, write to the log (observations or
+the acknowledgement marker). The write itself is the enforcement mechanism: it
+forces the mental check to surface as a recorded action, and it prevents the
+common failure mode where the skill is loaded but no observations are written
+until the user explicitly asks.
+
+**Deliverable-event flush:** Hard enforcement that hooks onto tool calls you are
+already making is the only reliable mechanism; soft prompts that rely on memory
+don't survive cognitive load during long substantive sessions (when the most
+insights surface). So tie observation-flushing to deliverable and workflow events
+that already involve a tool call. Whenever you present or render a major
+deliverable — `present_files`, a deck or PDF render, a staged skill file handed
+to the user — or complete a task/todo batch, flush any pending observations to
+the log at that moment, before moving on. These are natural, already-occurring
+checkpoints; piggy-backing the flush onto them means the write happens as a
+side effect of work you were doing anyway, rather than depending on a separate
+act of memory.
+
+**Your own delegates are concurrent writers.** A subagent dispatched into the
+same project has this skill active in its own context and appends to the same
+log, so it consumes numbers between your read and your write. Collisions are
+structural in any fan-out workflow, not a rare parallel-human accident — which
+is exactly why the pre-write assertion below matters most in the workflows that
+spawn helpers. When dispatching, say who owns logging for the session, or two
+writers record the same incident from different angles under different numbers.
+
+**Numbering discipline (mandatory, every append):**
+
+1. _Pre-check:_ read the actual log and find the highest existing number —
+   never trust session memory:
+
+   ```bash
+   # GNU grep:
+   grep -oP '### Observation \K\d+' log.md | sort -n | tail -1
+   # macOS / POSIX:
+   grep -o '### Observation [0-9]*' log.md | grep -o '[0-9]*' | sort -n | tail -1
+   ```
+
+2. _Pre-write assertion:_ immediately before appending, confirm the proposed
+   number doesn't already exist:
+
+   ```bash
+   PROPOSED=$(( $(grep -oP '### Observation \K\d+' log.md | sort -n | tail -1) + 1 ))
+   grep -qE "^### Observation ${PROPOSED}:" log.md && {
+     echo "COLLISION on #${PROPOSED}"; exit 1; }
+   ```
+
+   If it fires, increment past all existing numbers and re-check (and log a
+   meta-observation — it signals a parallel-session collision).
+
+3. _Post-write verification:_ after appending, count occurrences of the
+   number; if >1, a parallel writer collided between check and write —
+   renumber YOUR entry to max+1. Identify your entry from your own append
+   operation (capture the file's line count immediately before and after
+   your `>>`; your entry starts at the old line count + 1) — do NOT
+   re-grep and take the last occurrence, which may be a colliding writer's
+   entry appended after yours. After any `sed` renumber, re-read the
+   affected line to confirm the substitution actually took effect — a
+   line-addressed `s///` whose target shifted finds no match and still
+   exits 0. Pre-write catches stale reads; only a post-write check catches
+   the race. The pattern for shared logs written by parallel agents is
+   check-then-act-then-verify.
+
+**Log-write safety — never let a mutation span entry boundaries:** When
+mutating the log programmatically (marking entries ACTIONED/DECLINED,
+archiving, renumbering), a greedy or DOTALL pattern over the whole file can
+silently swallow everything from one match to EOF. This has happened: a
+`.*$` under `re.S` over the multi-entry file captured from one entry's
+Status line to end-of-file and overwrote 16 later entries in a single
+substitution. The log is shared state across many entries; mutate it one
+bounded entry at a time and verify every mutation.
+
+1. **Re-read and merge immediately before any write-back.** Any full-file
+   rewrite (archival, renumbering, reassembly from chunks) built from a
+   snapshot destroys whatever concurrent sessions appended after that
+   snapshot — the write-back succeeds, the victim gets no error, and the
+   loss is invisible. This has happened in production: a parallel session's
+   write-back erased two entries appended minutes earlier, hours after the
+   exact failure mode had been documented. So: take the snapshot, prepare
+   the mutation, then — immediately before writing — re-read the live log
+   and diff against the snapshot. If new entries appeared, merge them into
+   the write-back (or rebuild from the fresh read). Never write back a
+   stale snapshot.
+
+2. **Isolate the target entry, or anchor to a single line.** Either split
+   the log on `### Observation N:` headers, edit the TARGET entry's chunk in
+   isolation, and reassemble — OR, for a status-only edit, use a strictly
+   line-anchored multiline substitution that cannot cross a newline, e.g.
+   `re.sub(r'(?m)^(\s*-?\s*)\*\*Status:\*\*.*$', ...)` (multiline `^...$`
+   bounds the match to one line). NEVER use a DOTALL/greedy pattern across
+   the multi-entry file.
+
+3. **Assert a structural invariant against the LIVE pre-write file.** Count
+   `### Observation` headers in the live file immediately before writing and
+   again after. For a status-only edit the count MUST be unchanged; for
+   archival or append it must change by exactly the expected number. The
+   baseline must be the live file at write time, NOT your session's earlier
+   snapshot — an invariant computed against a stale snapshot validates that
+   you wrote what you intended while still destroying what others wrote in
+   between. Fail loudly if the count is off.
+
+4. **Keep the pre-write backup.** Copy `log.md` before any programmatic
+   mutation. This is what made full recovery trivial when the truncation
+   above occurred — it turned a destructive bug into a non-event.
+
+5. **Verify your entries SURVIVED, not just that they were written.** A
+   successful append proves nothing an hour later — a concurrent session's
+   write-back can silently delete it, and only the destroying session gets
+   any signal (none). Before surfacing observations at session end, grep
+   the log for every entry number this session wrote and confirm each still
+   exists exactly once; re-append any that are missing (with fresh numbers)
+   and log a meta-observation about the collision.
+
+Principle: a log shared across many entries must be mutated one bounded
+entry at a time; every rewrite must be based on a fresh read, verified by a
+structural invariant against the live pre-write file, and backed up. Writers
+must verify survival, not just successful writes — in a concurrent erase,
+the victim gets no error.
+
+**Format and insertion:** always `### Observation NNN:`, always appended to
+the END of the log, never mid-file, never alternative ID formats. One
+format, one insertion point. **Every new observation MUST include
+`**Status:** OPEN` as its first field — this is mandatory at write time, not
+optional.** Reviews classify entries by their Status line; an observation
+written without one is invisible to any status-filtered pass and risks being
+silently skipped instead of triaged.
+
+```markdown
+### Observation [N]: [Short descriptive title]
+
+**Status:** OPEN
+**Date:** [date]
+**Session context:** [what task was being worked on]
+**Skill:** [existing skill name, or "New skill candidate: [working name]"]
+**Type:** [open-source | internal]
+**Phase/Area:** [which part of the skill or workflow]
+
+**Issue:** [What happened — specific enough to understand weeks later
+without the original conversation.]
+
+**Suggested improvement:** [Concrete change. For existing skills, name the
+section or rule; for new skills, scope and key components.]
+
+**Principle:** [The generalisable takeaway — the most important field.]
+```
+
+**Context preservation:** if an observation depends on session-local data
+(uploads, API output), save that context into the workspace first and add a
+`**Reference file:**` line — an observation whose evidence dies with the
+session is incomplete.
+
+**Confidentiality at logging time:** for `type: open-source` observations,
+the Issue/Improvement fields may reference specifics for context, but the
+Principle must be fully generalised — no client names, domains, or details
+traceable to a real project. Full confidentiality layers for skill
+authoring: `references/skill-authoring.md`.
+
+## Referencing Observations
+
+When citing an observation by number — in conversation, in a review report,
+or from within another observation — the number must come from the entry's
+literal `### Observation N:` header line. Never cite an observation number
+that wasn't read from that header.
+
+- **Search-tool line numbers are positional metadata, not IDs.** `grep -n`
+  prefixes every match with a line number; when a match lands mid-entry
+  (e.g., on a Session context or Principle line rather than the header),
+  that line number is NOT the observation number. Resolve to the owning
+  header first — scan backwards from the matched line to the nearest
+  preceding `### Observation N:` header and take the number from there
+  (e.g., an awk backwards-scan, or re-grep for `^### Observation` and pick
+  the last header line before the match).
+- **Plausibility check (cheap second layer):** before quoting any
+  observation number, compare it against the known counter range — the
+  highest `### Observation N:` header in the log. A number outside that
+  range (e.g., citing #1365 when the log's counter is at #766) is almost
+  certainly a line number or other positional artefact misread as an ID.
+
+The general rule: IDs must come from the record's own identifier field,
+never from the positional metadata of the search tool that found it.
+
+## Taxonomy (quick version)
+
+**Open-source** — client-agnostic, methodology-driven, useful to other
+practitioners. **Internal** — contains user/client/project specifics or
+personal preferences. Default to open-source when it could go either way,
+stripping specifics. The boundary is also a confidentiality boundary. Full
+requirements (attribution, licensing, structure): `references/skill-authoring.md`.
+
+## Archival on Write
+
+On every log write, first move already-resolved entries to
+`skill-observations/archive/log-[YYYY-MM-DD].md` (preserving the log header
+in the archive). "Already resolved" is decided by date, read from the file:
+a resolved status MUST record its date — `ACTIONED (YYYY-MM-DD) — [what was
+done]` / `DECLINED (YYYY-MM-DD) — [reason]` — and archival moves only
+entries whose recorded date is before today. Entries resolved today stay in
+the active log until the next day, no matter which session resolved them:
+the grace period lives in the file, never in session memory, so it holds
+across parallel and subsequent sessions. A resolved entry with no readable
+date gets today's date added instead of being archived. The active log
+keeps its header, status key, all OPEN entries, and the same-day-resolved
+ones.
+
+Archival is a read-filter-rewrite — the highest-risk mutation the log
+undergoes, and the one that has destroyed concurrent appends in production.
+It MUST follow the full Log-write safety sequence above: backup, re-read
+the live log immediately before writing back and merge any entries that
+appeared since the snapshot, then verify the post-write header count equals
+the live pre-write count minus exactly the number of archived entries.
+
+## Log Structure
+
+```markdown
+# Skill Observation Log
+
+Observations captured during task-oriented work.
+
+**Status key:** OPEN = not yet actioned | ACTIONED (YYYY-MM-DD) = skill
+updated/created | DECLINED (YYYY-MM-DD) = user decided not to pursue —
+resolved statuses always carry their resolution date
+
+---
+
+## [Date]
+
+### Observation 1: [Title]
+
+**Status:** OPEN
+[... full format ...]
+```
+
+## Surfacing Protocol
+
+Default: at end of session, as a grouped summary — improvements grouped by
+skill, new-skill candidates listed separately; for each, one sentence plus
+suggested type; ask which to act on. Surface earlier when an observation
+needs user input to be complete, when a skill is actively producing wrong
+output, or when observations cluster on one skill.
+
+**Default to log-and-defer.** Surfacing an observation is not an invitation
+to act on it. The default is log-and-defer: state that the observation is
+logged for the next review, and stop. Reserve in-session application
+strictly for the two triggers already defined under "Acting on
+Observations" — an explicit user request that names the action, or
+correcting a skill that is producing wrong output in the current session.
+
+Do NOT routinely offer a binary "apply now vs leave for next review" choice
+when surfacing observations. For users who run regular reviews, that offer is
+unwanted friction repeated every session. If a user has expressed a standing
+preference to always defer to the next review, suppress the in-session
+"act now?" offer entirely rather than asking each time.
+
+**Self-check before surfacing:** observations were logged throughout the
+whole session (including discussion phases); logged silently; each follows
+Issue → Improvement → Principle; each is typed; existing-skill items name
+the section; no open-source Principle contains client-identifying info;
+every appended observation carries a Status line (`**Status:** OPEN` at
+write time) — a statusless entry is invisible to any status-filtered review
+pass, so if any observation lacks one, add it now. Finally, run the
+survival check (Log-write safety rule 5): grep the log for every entry
+number this session wrote and confirm each still exists exactly once — a
+concurrent session's write-back deletes silently. Fix failures before
+surfacing.
+
+## Acting on Observations
+
+Act only in three contexts: (1) the comprehensive review (load
+`references/weekly-review.md`); (2) an explicit user request ("update X
+skill", "act on observation #N"); (3) in-session correction when a skill is
+producing wrong output the user should know about. Otherwise: log, don't
+act.
+
+When acting: small, clearly-additive, low-risk changes (a new rule, a
+clarification, a factual fix) may be applied directly. Substantial changes
+(restructuring, new capabilities, changed methodology) and all new-skill
+creation: load `references/skill-authoring.md` first and follow its editing
+and staging rules. If an observation reveals a principle that applies to
+skills generally, propose it for the cross-cutting principles file (see the
+same reference).

+# Environments, Activation Setup, and Handoff-Doc Mode
+
+Load this for setup questions, compaction/resume behaviour, or when running
+in an environment without filesystem access.
+
+## Recommended activation setup
+
+Description-level matching alone can miss invocation when the agent is
+focused on the task, so pair the skill with a configuration-level
+instruction (CLAUDE.md, project instructions, or equivalent):
+
+```
+At the start of any task-oriented session — any interaction where you will
+use tools and produce deliverables — invoke the task-observer skill before
+beginning work. This ensures skill improvement opportunities are captured
+throughout the session.
+
+When loading any skill, check the observation log for OPEN observations
+tagged to that skill. Apply their insights to the current work, even if
+the skill file hasn't been updated yet. This enables immediate application
+of observations before they're permanently integrated during the weekly
+review.
+```
+
+**Config detection (once per session):** with filesystem access, check the
+workspace root's CLAUDE.md (or equivalent) for a task-observer activation
+instruction — suggest adding it if absent, creating the file if none
+exists. Without filesystem access, check the system prompt / project
+instructions and suggest the user add the instruction there. Keep the
+suggestion to a sentence or two.
+
+**Anti-pattern:** don't chain activation through another skill — load
+task-observer and related skills independently from configuration; a broken
+chain silences all observation activity.
+
+**If CLAUDE.md (or the equivalent config) is governance-protected:** some
+setups guard shared config files with hooks or file-protection rules that
+deny agent edits. If an edit to the config is denied, never retry the same
+edit blindly and never attempt to bypass the guard — a denial is the
+governance system working as intended, and a silent skip is just as bad
+(the user believes activation is set up when only description-level
+matching is active). Surface the denial to the user and offer these
+fallbacks: (a) ask the user to paste the activation block into the file
+themselves; (b) if the user's environment provides its own
+temporary-authorization mechanism (a marker file, an environment variable,
+or similar), ask the user to authorize the edit through that mechanism and
+revoke it afterwards; (c) where the platform supports unguarded
+project-level instruction files, add the activation instruction there
+instead. Never assume unrestricted edit access to shared or
+governance-tracked config — many setups gate exactly those files.
+
+## Compaction behaviour
+
+When context compacts mid-task, the CLAUDE.md structural trigger re-invokes
+this skill on the resumed session automatically (the resumed session reads
+CLAUDE.md anew). Observations before and after compaction append to the
+same log with continuous numbering. This is the main reason the structural
+trigger exists — a resumed session's opening message may not match the
+description triggers.
+
+## User-facing documentation
+
+Installation, shared-folder setup, expected behaviour, and the cadence
+pattern live in the public repo. These links are for the human reader:
+share them with the user rather than fetching the pages — the skill's
+behaviour is defined entirely by its own files, never by external content:

+## Handoff-doc mode (no persistent storage)
+
+The methodology is environment-independent; only persistence varies. In
+web-chat-style environments, collect observations in-session and deliver
+them in a structured handoff document the user stores and pastes into the
+next session. **Offer the handoff proactively when the conversation winds
+down** — a premature offer is a minor interruption; a missing one is lost
+work.
+

+
+## Handoff-doc analysis (when one arrives)
+
+1. Log all explicitly stated observations first, unfiltered.
+2. Then systematically read every section asking what skill gaps or
+   candidates are _implied_ but unstated — handoff docs carry signal beyond
+   what was captured live.
+3. Pay special attention to action items (each may imply a missing skill),
+   open questions (ambiguity signals a decision-framework gap), the
+   work-completed narrative (patterns may reveal meta-skills), and session
+   notes.
+4. Attribute derived observations as coming from handoff-doc analysis, not
+   the original session.

+# Skill Authoring — taxonomy, licensing, confidentiality, editing rules
+
+Load this before creating any skill or making substantial changes to one.
+
+## Taxonomy in full
+
+**Open-source skills** are client-agnostic and methodology-driven.
+Recognise one: the methodology works across clients and contexts; no
+proprietary information is needed; other practitioners would find it
+valuable; it captures a process, not personal preferences. Required
+elements: the body identifies itself as open-source; author attribution
+block (template below); a licence statement; a feedback/support section
+routing methodology feedback to the creator; tool-agnostic language
+(capabilities like "browser access", not product names); built-in
+enforcement (see Pre-Flight Principle). Default to open-source when a skill
+could go either way — strip specifics and generalise.
+
+**Internal skills** contain user/client/project specifics, personal
+preferences, or context only the user has. They identify themselves as
+internal, need no attribution or licence, and can be shorter and less
+formal. They're working documents — keep them current, don't over-engineer.
+
+## The Pre-Flight Principle
+
+Rules documented in a skill are not reliably followed during creative flow.
+Every skill with explicit rules needs a verification step where the agent
+re-reads the rules and checks its output against them before delivery. When
+creating or improving any skill ask: "Does it have rules? Does it have a
+mechanism to enforce them?" If not, add one.
+
+**Embedded commands are pre-flight items too — execute before you ship.**
+Prose rules and command snippets fail differently: a prose rule is
+re-interpreted in context on every run, so ambiguity can be caught at
+execution time; an embedded command runs verbatim, unattended, forever —
+and a subtly wrong command can read as correct on every re-read
+(`git log -1 --format=%cI --reverse` returns the NEWEST commit, because
+`-1` applies before `--reverse`, while the plausible reading is "oldest").
+Any command embedded in a skill must be executed once against real data,
+with its output inspected for plausibility, before the skill file is
+saved. An unverified snippet is among the highest-risk lines in a skill:
+it ships bugs that no re-read can catch.
+
+## Lean Content
+
+A skill should contain only content that changes the agent's behaviour at
+execution time. Move changelogs, credits beyond the author block, long
+backstories, and maintainer notes to supporting docs. Do NOT cut examples,
+anti-patterns, or worked scenarios — bare rules get violated more than
+rules with context. Test: would removing it change behaviour? Keep
+per-session rules in the skill body and episodic material in reference
+files loaded on demand (progressive disclosure) — a skill loaded every
+session is fixed overhead and should be audited like one.
+
+## Licensing
+
+Include a licence statement in the preamble and a LICENSE file with full
+text. Options: **CC BY 4.0** (prose/methodology skills; share and adapt
+with credit — recommended default), **MIT** (code-heavy, permissive),
+**Apache 2.0** (MIT plus patent grant), **CC BY-SA 4.0** (share-alike
+derivatives), **GPL family** (strong copyleft). The author chooses; the
+requirement is that there is one.
+
+**Private client sharing** is a third channel with its own rights framing:
+a client-agnostic skill shared privately with one client is NOT open source
+and NOT internal. Keep the attribution block; replace the licence statement
+with a short usage notice (e.g., "shared privately for internal use; please
+don't redistribute without checking with the author"); no LICENSE file
+needed. All confidentiality sweeps still apply — other-client information
+must not leak even when the recipient is a known client. Do not treat "not
+internal" as "therefore open source": distribution channel determines the
+rights framing, not just the feedback routing (see the distribution-channel
+note below).
+
+## Author Attribution Template
+
+```markdown
+**Created by [Author Name] / [website or contact link]**
+
+[1-2 sentence description of what the skill does and its provenance.]
+
+**Licence:** This skill is released under [LICENCE NAME]. [One-sentence
+summary — e.g., "share and adapt for any purpose with credit."]
+
+**Feedback & Support:** If questions arise about the methodology, or the
+user gives constructive feedback on output derived from this skill, suggest
+an issue on the skill's public repository — public feedback benefits every
+user. Direct contact: [contact link]. If feedback stems from the
+methodology, log it and suggest sharing it; if from the agent not following
+the skill's rules, acknowledge and correct.
+```
+
+**Distribution-channel note:** the template's feedback routing assumes
+public-repo distribution. Only reference a repository URL once that
+repository actually exists — never write a reference to an artefact before
+the artefact exists. Until publication, route feedback to direct author
+contact only; when the skill is published, inject the repo URL at publish
+time. When an open-source skill is distributed privately (shared directly
+with a client rather than published), keep the direct-author-contact
+routing — a public-repo reference is wrong for that channel.
+
+## Confidentiality layers
+
+The open-source/internal boundary is a confidentiality boundary; enforce it
+in layers so any one catches what others miss:
+
+1. **Observation-level stripping** — open-source observations carry a fully
+   generalised Principle (covered in SKILL.md).
+2. **Pre-creation review** — before drafting/regenerating an open-source
+   skill, scan all source material for client names, URLs, domains,
+   internal terminology, identifiably-specific structures; replace with
+   generic equivalents first.
+3. **Post-draft sweep** — a separate re-read focused only on leakage:
+   proper nouns besides the author, domains/URLs/project identifiers,
+   vertical details that narrow the client, examples traceable to a real
+   project.
+4. **Structural principle** — when in doubt, remove. Slightly more generic
+   beats slightly leaky.
+5. **Cross-product re-identifiability sweep** — the final pass before any
+   public release. Individually-sanitised examples can combine to identify
+   a client (enumerated counts matching a public client list; specific
+   numbers in a thin vertical; thinly-disguised placeholder names in the
+   same vertical as a real client). List every example and its fields
+   (vertical, geography, numbers, timing, counts); ask whether a reader
+   with the author's public client list could map them; mitigate by
+   blurring counts, widening verticals, using illustrative ranges, or
+   consolidating into composites. Run this mechanically — the author is the
+   least reliable judge because they know the ground truth.
+
+## Editing skills — always start from the live file
+
+1. The live file is the authoritative source: in Claude Code,
+   `~/.claude/skills/{skill}/SKILL.md`; in Cowork, a read-only mount at
+   `.claude/skills/{skill}/SKILL.md` (writes fail with EROFS by design).
+   Do not edit skill files in place, in any environment — staging-only is
+   what keeps the autonomous review safe.
+2. Always base edits on a fresh read of the live file — never a workspace
+   copy, prior draft, or memory.
+3. Before overwriting any staged/workspace copy, diff it against the live
+   file; if they differ, rebase your edits on the live version. (Observed
+   failure: an update built on a stale snapshot silently dropped two
+   sections added to the live skill the same day; only a pre-merge diff
+   caught it.)
+4. Stage every update to
+   `[workspace folder]/skill-updates/[date]/[skill-name]/` — the FULL
+   skill directory (SKILL.md plus references/, scripts/, assets/ where
+   present), never SKILL.md alone — and present it for review and
+   installation; nothing goes live until the user installs it. Where no
+   presentation/upload tool exists (e.g. Claude Code CLI), present the
+   staged path and a change summary in chat instead; staging-only applies
+   in every environment — it's the review loop's safety property, not a
+   filesystem constraint. For any
+   skill with supporting files, zip the staged directory into a `.skill`
+   bundle and present the bundle, never the bare SKILL.md: a single-file
+   delivery convention applied to a multi-file skill truncates it
+   silently (the install succeeds, the skill loads, and the missing
+   pieces only surface when a reference load or script call fails
+   mid-task). **Pre-delivery gate — two items, checked at the moment of
+   delivery, not just at drafting time:** (1) every `references/`,
+   `scripts/`, `assets/` path in the staged SKILL.md body has its file in
+   the staged set; (2) if the skill is multi-file, the delivery artefact
+   is the `.skill` bundle — bare file links fail this gate even when all
+   files are staged. (Reading this rule while drafting does not enforce
+   it at delivery; run the gate as the last step before presenting.)
+   Packaging hygiene: before zipping, sweep the staged tree for build
+   artefacts (`__pycache__/`, `*.pyc`, `.DS_Store`, `.~lock.*`) left by
+   in-session checks, and read the archive listing back after zipping —
+   the listing is the cheap verification that catches leaked artefacts.
+5. When seeding a staged copy by copying from the read-only mount, reset
+   write permissions immediately (`chmod -R u+w` on the staged path, or
+   `cp --no-preserve=mode`) — the mount's read-only mode travels with
+   the copy, for directories as well as files, and the follow-up edit
+   otherwise fails with a permission error.
+6. Match process rigour to the change: complex/open-source/uncertain design
+   → use the skill-creator if available; internal skills with requirements
+   already established in conversation → write directly, flagging
+   substantial changes for review.
+
+## Verifying relocations and restructures
+
+When content is relocated verbatim (splits into core + references, merges,
+restructures), "nothing was lost" is checkable mechanically — but only with
+a two-tier check:
+
+1. Enumerate every added/moved line via `diff` of the old base vs the new
+   base.
+2. Exact-match each non-empty line against the restructured file set
+   (`grep -F`).
+3. For misses, substance-check via a distinctive mid-line substring before
+   concluding loss — most misses are container artifacts (heading-level
+   changes, list-to-prose adaptation, re-wrapped lines splitting a phrase
+   across newlines), not real losses.
+4. Word-count sanity check per file.
+
+One tier alone either misses losses (substance-only) or cries wolf
+(exact-only). Additionally, inventory the original's enforcement
+mechanisms (checkpoints, assertions, invariants, mandatory-write rules,
+defaults) as an explicit checklist — compression preferentially destroys
+enforcement machinery because it reads as redundancy — and sweep any "pure
+restructuring" change for net-new behaviour, which hides well in a large
+rewording diff.
+
+## New skills
+
+Use the skill-creator when available, passing the observation(s) as the
+brief. Determine type early: open-source → strip and generalise; internal →
+include specifics freely; uncertain → default open-source and let the user
+add internal detail afterwards.
+
+## Principle Propagation
+
+When an observation's Principle applies to skills in general, log it with
+`Skill: All skills` and surface it; if the user approves, add it to
+`[workspace folder]/skill-observations/cross-cutting-principles.md`. That
+file is a mandatory checklist during any skill creation or regeneration.
+The user chooses propagation timing: immediate (update all skills now — for
+things like confidentiality rules) or opportunistic (apply at each skill's
+next update).

+# Comprehensive Review (scheduled or fallback)
+
+Cross-checks all OPEN observations against all skills, propagates
+cross-cutting principles, and applies improvements that don't need user
+input. Two modes:
+
+- **Scheduled autonomous review (preferred):** a recurring task (e.g.
+  Mon/Wed/Fri mornings) via the platform's scheduler. Runs without the user
+  present and applies non-escalated observations autonomously.
+- **In-session 7-day fallback:** pending at session start when BOTH are
+  true: no scheduled review is registered (or none succeeded in 7+ days),
+  AND `skill-observations/last-review-date.txt` contains `never` or a date
+  more than 7 days old (a missing file is recreated with `never` — see
+  Session Start steps 1 and 3; the file's value is authoritative, a date
+  means a review actually ran). In an interactive session a pending
+  fallback surfaces as a one-line offer and runs only if the user opts in
+  (SKILL.md, Session Start step 3) — it never gates the user's task.
+
+**Reachability — where does scheduled work actually run?** Scheduled mode
+requires the scheduling agent's execution environment to read and write
+the workspace folder. Persistence and execution context are independent
+axes: knowing where the state lives is not enough — check whether the
+scheduler runs somewhere that can reach it. Three regimes:
+
+1. **Shared filesystem** (e.g. Cowork's mounted folder): scheduled mode
+   works as described.
+2. **Local-only filesystem with a cloud scheduler** (e.g. remote routines
+   that run on hosted infrastructure): scheduled mode is physically broken
+   — the remote agent cannot read `skill-observations/` or stage updates
+   to `skill-updates/`. Do not register a routine. Recommend a recurring
+   calendar reminder plus a manual "run the skill review" trigger in a
+   local session, or syncing the observation log to storage the scheduler
+   can reach (e.g. a git repository it can clone).
+3. **Local-only filesystem with a local scheduler** (cron, Task Scheduler,
+   a terminal-resident loop): works, but the user must keep the local
+   agent runnable.
+
+## Approval policy
+
+**Interactive (user present):** always present observations grouped by
+skill (number, title, one-sentence summary), flag judgment calls as "needs
+your input", and wait for blanket or selective approval before applying.
+
+**Scheduled autonomous (user absent):** apply non-escalated observations by
+default — safety comes from the staging-plus-review pattern (nothing is
+live until the user installs it). **Escalate without applying** when: (1)
+the observation proposes a NEW skill (naming/scope/type/licence need the
+user); (2) it removes or substantially restructures existing content; (3)
+it self-flags uncertainty ("not sure if…", "worth discussing…"); (4) two
+observations conflict. A scheduled run should still apply every
+non-escalated item — a review that applies nothing is just a report
+generator.
+
+## Steps
+
+**Step 0 — recommend scheduled setup (fallback mode only).** Ordering
+guard: run Step 1's no-observations short-circuit FIRST — if there are no
+OPEN observations and no outstanding principles, skip Step 0 entirely and
+just update the timestamp. A brand-new install must never get a setup
+prompt before it has done any work. Otherwise: check
+`skill-observations/scheduled-review-decline.txt`: if under 30 days old and
+the fallback isn't firing repeatedly, skip. Check for a registered
+scheduled task (scheduler presence or
+`skill-observations/scheduler-registered.txt`); if found, skip. Before
+offering, check reachability (see the regimes above): if the platform's
+scheduler runs where it cannot reach the workspace folder (regime 2), do
+NOT offer registration — recommend the calendar-reminder-plus-manual-
+trigger pattern instead, and skip the rest of this step. Otherwise
+offer to set one up. Yes → register via the platform scheduler (Cowork:
+`create-shortcut` / `set_scheduled_task`; terminal: cron), name it
+`weekly-skill-review`, use the draft prompt at
+`skill-observations/scheduled-task-draft.md` if present, then verify the
+registration actually succeeded (the scheduler lists the task, or the
+platform confirmed creation) BEFORE writing today's date to
+`scheduler-registered.txt`. If registration fails or can't be verified, do
+NOT write the marker — the marker would permanently suppress the fallback
+while no review ever runs. Tell the user registration failed and leave the
+fallback active. No → write today's date to
+`scheduled-review-decline.txt` (suppresses for 30 days; repeated fallback
+firings within the window re-surface the offer). No scheduler available in
+this environment → skip silently.
+
+**Step 1 — load.** Archive entries resolved in _previous_ sessions (see
+Archival on Write in SKILL.md). Read the observation log.
+
+Build the work queue from the structural identifiers, not from a status
+filter. The OPEN set is defined as: **status is literally OPEN, OR the
+observation has no Status line at all.** Concretely:
+
+1. Enumerate all `### Observation N:` headers first — this is the
+   authoritative list of entries in the log.
+2. For each header, classify the entry's status by looking for a
+   `**Status:**` line within its body. Treat a missing, blank, or any
+   non-ACTIONED / non-DECLINED status as OPEN.
+3. Never derive the work queue from a `grep '**Status:** OPEN'` alone.
+   Derive it from the header list minus the resolved (ACTIONED /
+   DECLINED) entries. A grep on an optional field silently drops every
+   entry missing that field — the review then confidently reports a
+   clean log while a backlog of untriaged observations is skipped.
+
+**Reconciliation guard:** before proceeding, assert that
+`count(### Observation headers) == count(status-classified entries)`.
+If the counts differ, the delta is statusless entries — surface and
+triage them (as OPEN) rather than proceeding as if the log were clean.
+
+Also read all active cross-cutting principles. If there are no OPEN
+observations and no outstanding principles: report "no open observations
+or outstanding principles", update the timestamp, and stop.
+
+**Step 2 — inventory skills.** List all skills (system prompt
+`<available_skills>` or the skills directory). Only user-owned custom
+skills can be updated. Known read-only system skills: docx, pdf, xlsx,
+pptx, skill-creator, schedule (grow this list when an update fails for
+permissions). Observations targeting a system skill are NOT skipped — route
+them to a complementary user-owned `{system-skill}-extras` skill containing
+only the delta, creating it if needed and noting the pairing in
+configuration.
+
+**Step 3 — cross-check observations.** Evaluate every OPEN observation
+against every skill — not just the skill named in its header; Principles
+often generalise. Build skill → [relevant observations]. Interactive:
+present all of it and await approval. Autonomous: apply the approval policy
+above and continue.
+
+**Step 4 — cross-check principles.** Flag every skill that doesn't yet
+comply with each active cross-cutting principle.
+
+**Step 5 — apply.** For each skill with approved/non-escalated items,
+produce an updated SKILL.md: integrate insights into the sections where
+they belong (never append an observations list at the bottom); preserve
+structure, voice, and attribution; place new rules where they logically
+live. Follow the editing rules in `references/skill-authoring.md` (live
+file as base, staging, diff-before-overwrite).
+
+**Step 6 — mark ACTIONED.** Update each applied observation's status:
+`ACTIONED (YYYY-MM-DD) — Applied to [skill-name] (weekly review)`. The
+date immediately after the status word is load-bearing: archival is gated
+on it (entries archive only when it's before today), so a dateless mark
+breaks the cross-session grace period. Do NOT archive same-session — the
+next log write on a later day archives them.
+
+**Step 7 — timestamp.** Write today's date to
+`skill-observations/last-review-date.txt`.
+
+**Step 8 — deliver and summarise.** Stage updated skills (see Delivery
+below), then present:
+
+```
+## Weekly Skill Review Complete — [date]
+
+Updated skills ([N] observations, [N] principles applied):
+
+**[skill-name]** — [1-sentence change summary]; observations #[N], #[N]
+
+### Observations Actioned
+[numbers and titles]
+
+### Skipped (needs manual review)
+[items with reasons]
+```
+
+Wait for the user to acknowledge before other work.
+
+## Constraints
+
+- Don't modify observation entries beyond their status field.
+- Don't create new skills in a review — note candidates for the user to
+  action via the skill-creator.
+- Unsure how to integrate an observation → skip it and say so in the
+  summary.
+- Treat internal observations with the same rigour as open-source.
+
+## Delivering updated skills
+
+Save each updated skill to
+`[workspace folder]/skill-updates/[date]/[skill-name]/` — the FULL skill
+directory (SKILL.md plus references/, scripts/, assets/ where present),
+never SKILL.md alone — and present it for review and installation. In
+Cowork: via `present_files` and its upload button. In environments without
+a presentation tool (e.g. Claude Code CLI): report the staged path and a
+change summary in chat and let the user review and install from there.
+Never write to the live skill directly, even where the skills directory is
+writable — staging-only is a deliberate safety property of the review loop
+(nothing goes live without the user's sign-off), not a filesystem
+constraint. For any skill with
+supporting files, zip the staged directory into a `.skill` bundle and
+present the bundle; a bare SKILL.md install silently truncates a
+multi-file skill. Pre-delivery gate (two items, run as the last step
+before presenting): (1) grep the staged SKILL.md body for `references/`,
+`scripts/`, `assets/` paths and fail the delivery if any referenced file
+is missing from the staged set; (2) for multi-file skills, fail the
+delivery if the artefact being presented is bare file links rather than
+the `.skill` bundle. Sweep build artefacts (`__pycache__/`, `*.pyc`,
+`.DS_Store`, `.~lock.*`) before zipping and read the archive listing back
+after. When seeding staged
+copies from the read-only mount, `chmod -R u+w` the staged path first —
+the mount's read-only mode travels with the copy, for directories as
+well as files. Do not edit skill files in place — nothing goes live
+until the user installs it. **Keep-two rule:** for any skill, keep only
+the two most recent date directories under `skill-updates/`; delete
+older ones.

+    `You own this CLUSTER for this run: no other agent has this file as its cluster, so fix ALL of the ` +
+    `findings below together rather than one at a time. But cluster fixes may share a file (rule 4 cuts ` +
+    `both ways), so another cluster's root-cause edit can still land in this file while you work. ` +
+    `Re-read the exact region you are about to edit immediately before each edit rather than trusting a ` +
+    `full-file read from the start of your turn, and treat any editor warning that the file changed ` +
+    `since you last read it as a signal to re-read and re-target, never to force the edit through.\n\n` +
+    `RULES\n` +
+    `  1. Test first. For each finding, write a test that FAILS against the current code before you ` +
+    `change anything, and run it to watch it fail. A test that passes before the fix does not pin the ` +
+    `bug and will be rejected mechanically later.\n` +
+    `  2. Never make a failing test pass by weakening an assertion. The existing suite is green and must ` +
+    `stay green on its current assertions.\n` +
+    `  3. Fix the ROOT CAUSE. Grep every caller of the function you are about to change. One guard in a ` +
+    `shared function beats a guard in every caller, and patching only the path a finding names leaves its ` +
+    `siblings broken.\n` +
+    `  4. You may edit a shared file outside your own cluster (${cluster.file}) when that is where the ` +
+    `root cause lives. If you do, you MUST list every SOURCE file you modified - including this cluster's ` +
+    `own file - in touchedPaths, repo-relative with forward slashes. Test files belong in testPath, not ` +
+    `touchedPaths. If you regenerate shared generated output (sqlc, protocol), list EVERY generated ` +
+    `file the regeneration changed - check with git status --porcelain (read-only, allowed despite ` +
+    `rule 6), do not guess: an unlisted generated file defeats the cross-cluster overlap guard.\n` +
+    `  5. Because several findings share this file, look for one change that closes more than one of them ` +
+    `before writing separate patches.\n` +
+    `  6. DO NOT run any git command. No add, no commit, no stash, no checkout. Other agents are working ` +
+    `in this same working tree and git operations collide on the index lock. Leave your changes in the ` +
+    `working tree; a later serial phase commits them.\n` +
+    `  7. If a finding is wrong, or the correct fix is a deliberate product decision you should not make ` +
+    `alone, return outcome "declined" with a rationale. Do not invent a fix you do not believe in.\n` +

 ## Test Plan

+- [ ] `npm run check` passes from the repository root — the one entry point that
-- [ ] TypeScript check passes (`npx tsc --noEmit`)
+      runs what CI gates on. `check:server` / `check:client` / `check:rust` /
+      `check:hygiene` / `check:docs` run a single stack if that is all you touched

+      `Server/ws/message_types.go`, `Client/src/lib/protocolTypes.ts`,
+      `Client/src/generated/`, `.superpowers/FINDINGS.md`. CI fails on drift
 - [ ] Docs updated — anything under `docs/architecture/` (incl. `ux/`) whose
       "Source of truth" files this PR touches is updated in the same PR
       (their maintenance rule), and reference docs (`api.md`, `protocol.md`,
       `schema.md`, `server-configuration.md`) reflect any surface changes

+# Every ecosystem groups its updates into a single PR. Splitting per package
+# means each ecosystem's lockfile (go.sum, package-lock.json, Cargo.lock) is
+# rewritten once per PR, so merging any one of them invalidates all the rest —
+# every sibling then rebases and re-runs the full ~15 minute CI matrix. The
+# 2026-08-10 batch opened 17 PRs for one weekly refresh.
+#
+# Grouping also keeps release trains together. The OpenTelemetry modules move
+# in lockstep, and npm families version-lock their own packages with exact peer
+# pins (typescript-checker@9.6.0 requires core@9.6.0, not ^9.6.0), so a partial
+# merge is an ERESOLVE failure waiting to happen.
+#
+# Majors are ignored everywhere below, so each group only ever carries patch and
+# minor updates. If one member of a group is bad, add it to that ecosystem's
+# ignore list rather than ungrouping the rest.
+#
+# Each package root gets its own block rather than one block with `directories:`.
+# Grouping only works because a group rewrites exactly one lockfile; a block
+# spanning roots would put several lockfiles in one PR and reintroduce the very
+# conflict the grouping prevents. The three npm roots stay separate for the same
+# reason — see docs/contributing.md#dependency-policy for the measured decision

CHANGELOG.md

@@ -5,6 +5,383 @@ tooling (`npm run changelog`) auto-generates entries from commit messages
 on each release; this file is the curated counterpart that calls out
 behavioural changes operators must know about.
 
+## How to write an entry
+
+**Scannable lists, never walls of text.** A reader should be able to find what
+affects them in about ten seconds, without reading a paragraph they do not care
+about. Entries below `v1.2.0-alpha.3` do not follow this and are left as
+shipped history; everything from the next release forward does.
+
+The rules:
+
+1. **Open with what is user-visible and what is not.** Most releases carry a
+   mixture. Say which is which up front, so nobody reads twenty lines of
+   repository plumbing looking for a fix.
+2. **Group by the area a user recognises** — Login & connection, Voice,
+   Mentions, Messages & files, Accounts & admin, Desktop UI. Not by subsystem,
+   package, or which PR it came from.
+3. **One line per fix.** If it needs two lines, it needs two entries or it does
+   not belong here.
+4. **Say what was broken, then what it does now.** "Banned users could still
+   connect — ban is re-checked on connect." A reader must be able to tell
+   whether it bit them, without opening the PR.
+5. **Plain language.** Name the thing a user sees, not the function that owned
+   the bug. `voiceJoinLeaveCurrent` means nothing to an operator; "moderator
+   mute survives a channel move" does.
+6. **No `OC-*` ids, no file paths, no PR-body prose.** The ledger and the pull
+   request already carry those, and this file is the one place that does not
+   need them. A PR number is fine where it genuinely helps someone dig.
+7. **Counts belong in a summary line, not per item.** "62 fixes" once at the
+   top beats a number attached to every bullet.
+
+Anything a user cannot observe — repository layout, CI gates, generated-code
+ownership, dependency automation — gets **at most a short block at the end**,
+and only when it changes something a contributor or fork holder must do
+(a moved directory, a renamed module, a new required command).
+
+## Unreleased
+
+User-visible: one change to how updates roll out, and two new documents.
+Not user-visible: the protocol now carries a version number.
+
+### Login & connection
+
+- The client and server now agree on a protocol version ("epoch") when
+  connecting. This release is epoch 1; clients from v1.2.0-alpha.4 and earlier
+  still connect.
+- A client too old for its server is told "update the client" on the connect
+  screen, with the usual Update Now button — instead of failing in confusing
+  ways. The saved login is kept, so the updated client signs back in by
+  itself.
+- **Upgrade the server before the clients.** The server only offers client
+  releases that speak its own protocol epoch, so a protocol-changing release
+  reaches clients once the server runs it. Releases that do not change the
+  protocol are offered as before.
+
+### Admin panel
+
+- Creating or revoking an invite, and installing or uninstalling a plugin, now
+  show up in the audit log. Invite entries name the invite by id, never by
+  code.
+
+### Documentation
+
+- `docs/trust-model.md` answers "who can read my messages?": the server
+  operator can read text and files; voice, video and screen share are
+  end-to-end encrypted; what beta does not claim. Every claim cites the code
+  or test behind it.
+- `docs/architecture/plugins.md`: plugins are experimental, off by default,
+  compiled out of release binaries, and carry no API promise.
+
+### Repository
+
+- `protocol/schema.json` declares `protocol_epoch`; `npm run generate` emits it
+  as `ws.ProtocolEpoch` and `PROTOCOL_EPOCH`. Rules for bumping it:
+  `docs/protocol.md`, Compatibility.
+
+## v1.2.0-alpha.4
+
+**62 bug fixes**, all user-visible, plus repository work that changes nothing an
+operator can see. Fixes first; the repository half is the short block at the end.
+
+### Login & connection
+
+- Connecting with a failed role lookup silently made you a plain **member** — it
+  now fails closed instead of guessing.
+- **Banned users could still connect.** Ban status is re-checked on connect.
+- Reconnecting left a **phantom voice E2EE key holder** and a stale voice-channel
+  marker behind.
+- Typing indicators in DMs could **disconnect you** under load.
+
+### Voice
+
+- Moderator mute and deafen are **preserved across a channel move** — they were
+  silently dropped.
+- Voice E2EE keys **re-sync on reconnect**, and a departed peer's key is always
+  retired so a replayed announce cannot overwrite a fresh one.
+- A kicked client no longer receives frames.
+- A rolled-back join now reaches everyone present, including people without
+  permission to read the channel.
+- A **failed microphone unmute now shows as failed** instead of quietly
+  reporting you as unmuted.
+- Noise suppression rebuilds correctly after a microphone restart.
+
+### Mentions
+
+- **`@here` no longer behaves like `@everyone`** — the two are distinguished.
+- Mention badges are reversed on delete, purge and account deletion, and can no
+  longer be reversed twice.
+
+### Messages & files
+
+- Deleting a message now **actually deletes its attachment files**.
+- A failed avatar upload no longer deletes a committed file's reference.
+
+### Accounts & admin
+
+- The `require_2fa` enrollment gate misfired after a temporary ban lapsed, and
+  applied its precondition to unrelated settings.
+- A DM partner with no live connection now shows **offline everywhere** — it was
+  inconsistent between views.
+- Plugin installation rolls back properly when it fails.
+- The diagnostics endpoint honours trusted proxies.
+
+### Desktop app
+
+- Fixed event-listener leaks in the message list, member list, emoji picker,
+  quick switcher, sidebar popovers and drag-reorder.
+- Recent emoji, channel mutes and custom status are now **per-server** instead of
+  bleeding between servers.
+- The DM sidebar filter survives updates, the call button cannot redial, the
+  incoming-call banner uses nicknames, and Ctrl+I unwraps correctly on bold text.
+
+### Repository — no runtime effect
+
+Phases B0 and B1 of the
+[repository-health roadmap](docs/plans/repo-health-roadmap-2026-08-23.md).
+Desktop behaviour, release asset names and the update contract are unchanged by
+design. Three items affect anyone holding a working copy or a fork:
+
+- **`Client/tauri-client/` is now `Client/`** (#1411). Rebase an in-flight
+  branch rather than merging across the move.
+- **The Go module is now `github.com/J3vb/OwnCord/Server`** (#1417), was
+  `github.com/owncord/server`.
+- **The protocol schema is now `protocol/schema.json`** (#1417), was
+  `docs/protocol-schema.json`.
+
+One command runs what CI gates on, Windows and Linux, no `make` needed:
+`npm run bootstrap`, then `npm run check`. Go-only contributors still do not
+need Node.
+
+## v1.2.0-alpha.3
+
+- **fix:** eight bug-hunt batches closed **199 verified defects** since
+  `v1.2.0-alpha.2` — 30 in #1366/#1367, 110 in #1369–#1372, 34 in #1374 and
+  25 in #1375 — each fixed test-first with the failing assertion watched red
+  against the unpatched code. The behavioural consequences worth knowing
+  about are listed below; the rest are one-line correctness fixes with no
+  operator-visible change.
+- **security(client): voice E2EE was never actually enabled** (#1370). The
+  full ECDH/HKDF/AES-GCM key exchange completed, the room key was set, and
+  the UI showed 🔒 Secured — but `createRoom` never called
+  `room.setE2EEEnabled(true)`, so every audio and video frame reached the
+  SFU in plaintext. It is enabled now, and a dead E2EE worker is no longer
+  invisible to the Secured badge. Related voice-crypto fixes: a joining key
+  holder sent its room-key offers _before_ its own announce, so existing
+  participants dropped them as "unknown peer" (#1370, #1374); rotation
+  offers exceeded the server rate limit in large channels and permanently
+  starved the same peers; both rotation paths and the reconnect-to-Secured
+  path now carry session-generation guards; a departing peer's ephemeral
+  key is retired on leave so a replayed pre-leave announce cannot overwrite
+  the fresh key they rejoined with (#1372, #1374). The client also refreshed
+  its LiveKit token every 23 hours while the server mints it with a 5-minute
+  TTL, so auto-reconnect failed for any voice session older than five
+  minutes (#1370).
+- **security(server):** access-control holes (#1369–#1372, #1374, #1375) —
+  `voice_join` into a 1:1 DM had no block gate, so a blocked user could
+  enter the blocker's DM voice room; the attachment-serve admin bypass let
+  an ADMINISTRATOR download files from private DMs they were not in; the
+  archived-channel read-only gate covered `SendMessage` only, so edit,
+  reaction, pin, purge, delete and `channel_focus` still mutated or
+  subscribed to archived channels (every write sink now routes through one
+  `requireChannelWritable` gate); `EditMessage` and `handleReaction` DM
+  detection failed _open_ on a `GetChannel` error, skipping the block gate;
+  group-DM creation only block-checked the creator, letting a third party
+  force two users who blocked each other into a shared room; an invisible
+  user's real custom status leaked on both presence emitters; `PATCH
+/users/{id}` with `banned` + `role_id` committed and broadcast the ban
+  before authorizing the role change; admin API-token creation accepted a
+  negative `expires_hours` and minted a token that never expires; upload
+  rejections echoed raw storage errors (absolute server paths) to any
+  authenticated user; the GIF proxy's log redaction missed the
+  percent-encoded API key; `chat_command` was the only client message type
+  without a rate limiter while each frame ran a WASM plugin invocation; and
+  the login and typing rate limiters built their keys from _unvalidated_
+  input, letting an unauthenticated caller pin unbounded heap for six hours.
+- **fix(auth):** accounts whose username contains `'`, `"` or `&` were
+  permanently unloggable — registration HTML-escaped the name but login did
+  not — and a profile rename to such a name locked the user out (#1370). If
+  you had users hit this, they can log in again with no action on your side.
+  Also: message search returned 500 for any query containing a hyphen (the
+  one FTS5 operator the sanitizer allowlisted); usernames with an uppercase
+  non-ASCII letter could never be @mentioned; registration recorded the
+  reverse-proxy address as the session IP.
+- **server:** WS hub, reconnect and replay (#1369, #1371, #1372, #1374,
+  #1375) — REST DM events never bumped the visibility watermark, while
+  _every_ ordinary DM message re-emitted `dm_channel_open` and bumped the
+  global watermark, forcing every other client's next reconnect into a full
+  resync; the client's `lastSeq` was never reset by a full-ready resync and
+  desynced permanently; cold-tier replay had no interior-gap detection, so
+  events the persister dropped were skipped and presented as a complete
+  resume; `buildReady` swallowed three DB errors and shipped an
+  authoritative-looking empty snapshot (the client wiped its DM list, member
+  list and unread badges) and dropped the user's own live voice room when
+  not READ-visible; `channel_focus` could re-subscribe after a concurrent
+  visibility revoke, and role demotion's live-subscription revocation was
+  gated on a cosmetic role re-read; a failed reconnect handshake ran the
+  full disconnect teardown twice; presence events from every source now
+  share one ordered per-client FIFO.
+- **server:** voice lifecycle (#1369, #1371, #1374) — a stale join's
+  rollback deleted `voice_states` by user id alone, destroying a concurrent
+  newer membership; deleting a voice channel raced a concurrent `voice_join`
+  into a permanent hub/SFU ghost no sweep could heal; the stale-state sweep
+  could delete a just-committed join's row, leaving the client in voice with
+  no DB row; `handleVoiceJoin` handed out a live 5-minute LiveKit credential
+  _after_ a concurrent kick/move/revocation had already torn the membership
+  down (the token is now withheld); the `participant_left` webhook never
+  told the leaver, and a transient DB read error on `participant_joined`
+  ejected a legitimate participant mid-call; `voice_mod_move` lacked the
+  archived-channel gate; `CleanupVoiceForChannel` resolved an empty
+  `voice_leave` audience because both callers archive first. Camera and
+  screenshare now draw from the same per-channel `voice_max_video` budget —
+  screenshare had no cap check at all, and the camera gate did not count
+  screensharing occupants.
+- **server:** DM and message fan-out (#1369, #1371, #1372, #1375) — a DM
+  send, edit, delete or reaction survived a transient participant lookup
+  failure by silently dropping live fan-out to everyone including the
+  sender; emoji create/delete and group-DM creation tied their broadcasts to
+  the request context, so an aborted request committed the mutation and
+  skipped the event; slow mode consumed its cooldown token before content
+  validation, so a rejected send locked the composer for the full window; an
+  attachment-metadata read failure broadcast the message with no
+  attachments; `GET /channels/{id}/pins` had no LIMIT and failed permanently
+  past ~32k pins; pinning a soft-deleted message returned 500;
+  `LinkAttachmentsToMessage` no longer claims a user's live avatar as a
+  message attachment; `PATCH /channels/{id}` now rejects a blank name.
+- **server:** admin and plugins (#1369, #1370, #1372, #1375) — "Restore
+  backup" wrote to a hardcoded `data/chatserver.db`, so it silently no-oped
+  on any server with a configured `database.path`; the WAF inline engine
+  rejected every request body ≥ 1 MiB, breaking plugin install and large
+  avatar uploads when `waf_enabled` was on; self-account-deletion emitted no
+  `member_ban`, so every other client kept the deleted user; the admin live
+  log stream blanked every error attribute to `{}`; `CheckForUpdate` had no
+  in-flight dedupe and stampeded GitHub on cache expiry; a failed self-update
+  swap left every client counting down to a restart that never came (a
+  corrective `update_aborted` is now broadcast, and deferred cleanup runs
+  before the restart exits — on Windows that file-handle release is the
+  reason the restart exists). Plugin enable/re-install left
+  `plugins.enabled = 1` while the runtime instance was deactivated, and
+  uninstall reported success while the on-disk directory survived and
+  resurrected the plugin on the next start.
+- **fix(client):** voice reliability (#1366, #1367, #1370–#1372, #1374,
+  #1375) — a failed voice channel-switch left the user live in the call
+  (mic hot, audio flowing) with the voice UI hidden and no way to leave;
+  selecting the "Default" microphone (or losing the pinned one to a hot
+  unplug) never changed the capture device; a camera or screenshare disable
+  that completed while the enable's `publishTrack` was in flight left the
+  server and every peer believing it was on (`leaveVoice` and reconnect
+  teardown now bump the same generation guard); a `VIDEO_LIMIT` rollback
+  assumed the camera and tore down a working camera while leaving refused
+  screen tracks published — it now correlates by envelope id; auto-idle's
+  return-to-online `presence_update` was always swallowed by the 1-per-10s
+  limiter, so every user showed Idle to everyone else after their first idle
+  period; connection-quality degradation was never reported; a group-DM
+  decline silenced every other participant's ring and never reached the
+  caller.
+- **fix(client):** messaging and stores (#1366, #1367, #1369, #1372) —
+  re-opening a channel visited earlier in the session rendered a permanently
+  stale window (live broadcasts only cover the focused channel; the tail is
+  now refetched); the virtual scroll window never followed the scroll
+  position, so rows past the initial overscan rendered as blank space; a
+  scroll-up page past the 500-row cap deleted the user's pending/failed
+  rows, the only copy of their composed text; the scroll-to-bottom button
+  and "Jump to Present" pill scrolled out of view exactly when they became
+  visible; a user named exactly "System" had every message rendered as a
+  server notice with no moderation controls; DM permalinks failed until the
+  DM had been opened once; the reaction picker dropped the server's custom
+  emoji; Ctrl+K was dead with CapsLock on; the composer's slow-mode cooldown
+  was applied to whichever channel was mounted, not the one that sent.
+- **fix(client):** settings, session and platform (#1367, #1370–#1372,
+  #1375) — the built-in light theme overrode only 4 of ~45 tokens (composer
+  and inputs near-invisible), the Font Size slider and High Contrast toggle
+  were no-ops, and the tray Status menu bypassed the client's own status
+  state so a tray-set Do Not Disturb silenced nothing; a failed TOTP verify
+  tore down the overlay so the code could not be re-entered; channel
+  create/edit/delete modals locked up permanently on an API failure; login
+  to an IPv6-literal host was impossible; a host stored with an explicit
+  `:443` lost its bearer token and cert-pinned proxy on attachment fetches;
+  one malformed stored server profile discarded _all_ saved profiles; a
+  banned/revoked token reconnected forever if the session ended before
+  MainPage mounted; a previous server's block list, collapsed categories and
+  DM notes bled into the next server; the Rust HTTP proxy tunnel's data
+  phase had no deadline, so a remote that completed TLS then went silent
+  parked the connection forever (bounded at 600s — loose on purpose, this
+  path carries uploads); the autostart toggle raced its own write.
+- **infra:** observability, backups, guardrails and deployment hardening
+  (#1376). **`/health` now returns a real verdict** — hub dispatch-loop
+  liveness, a bounded DB ping and a free-disk check, answering **503 with a
+  subsystem reason** (`hub`, `database`, `disk`) when degraded; results are
+  cached so the unauthenticated endpoint cannot amplify load. Point uptime
+  monitors at it and treat any 503 as actionable. **The hub's panic breaker
+  now exits the process** so a supervisor can restart it, instead of leaving
+  broadcast delivery silently dead while clients still appear online — if
+  you run the bare binary without a supervisor, use the new hardened
+  `deploy/owncord.service` systemd unit (see "Running as a Linux Service").
+  **Backups now actually run:** `backup_schedule` and `backup_retention`
+  had existed in the admin panel since the initial schema but were never
+  read by any code; the 15-minute maintenance loop now enforces them,
+  verifies each backup with `PRAGMA integrity_check` (and again before a
+  restore may overwrite the live DB), and prunes by age keeping the newest.
+  Expect backup files to start appearing and pruning for the first time.
+  `/api/v1/metrics` gains reconnect-tier, backpressure, DB-writer-wait,
+  permission-cache, `ws_conn_rejects` and `disk_free_mb` signals, and the
+  declared-but-never-recorded OTel instruments are wired. Upload storage
+  failures return **507** instead of blaming the client with a 400. A
+  single-process lock beside the SQLite file makes a second server process
+  fail fast instead of silently fighting the first. **Unknown config keys
+  now warn at startup** (a typo previously kept the default silently), and
+  startup warns when `admin_allowed_cidrs` is customized while
+  `trusted_proxies` is empty. Shutdown now joins the pruner and maintenance
+  loop before the DB closes, drains HTTP handlers into a live hub, and skips
+  the 5s client-notice window when nobody is connected. Write-path work:
+  no-op read-state UPSERTs are skipped, boot-time `ANALYZE` runs only when a
+  migration applied, role-scoped override changes evict only that role's
+  members from the permission cache, and connect/disconnect presence passes
+  through a 300ms latest-wins coalescer (wire format and seq ordering
+  unchanged).
+- **config:** new keys, all defaulting to current behaviour (#1376) —
+  `server.max_ws_connections` (0 = unlimited; over the cap answers 503 +
+  Retry-After), `server.metrics_allowed_cidrs` and
+  `server.livekit_webhook_allowed_cidrs` (both fall back to
+  `admin_allowed_cidrs`, so a central Prometheus scraper or an
+  externally-hosted LiveKit no longer requires widening the admin
+  perimeter), `database.max_readers` (0 = auto), `backup.dir`
+  (`data/backups`), `security.auth_rate_limit_multiplier` (1.0; raise for
+  shared-NAT communities), `event_persistence.replay_ring_size` (1000) and
+  `event_persistence.replay_cold_limit` (5000 — watch `reconnect_tier_full`
+  before raising). Three stored-but-inert admin settings (`server_icon`,
+  `max_upload_bytes`, `voice_quality`) are now shown read-only with a
+  pointer at the real `config.yaml` keys instead of pretending to apply.
+  Documented in `docs/server-configuration.md`.
+- **deploy:** new `chatserver healthcheck` subcommand probes `/health`
+  pinning the server's own certificate from disk (WebPKI when none exists,
+  i.e. ACME) and is now the docker-compose healthcheck — the distroless
+  image has no shell; plain `docker compose` only _surfaces_ unhealthy, pair
+  it with a watchdog for auto-restart. Compose gains json-file log rotation
+  (`10m` × 3) on both services. `release.yml` now cold-boots the freshly
+  built server binaries and Docker image and probes them healthy **before
+  anything is signed or pushed** — the release feed drives signed
+  self-updates, so a binary that compiled but died on boot would previously
+  have shipped itself to every auto-updating instance. New "Reverse Proxy
+  Topology" docs section (nginx snippet; only WebRTC media ports need to be
+  directly reachable, `/livekit/*` is already proxied). Release binaries
+  are built with Go 1.26.6 (stdlib CVE fixes flagged by govulncheck).
+- **migrations:** **031** normalizes legacy `sessions.expires_at` values to
+  RFC3339-UTC and adds `idx_sessions_expires_at`, so the 15-minute expired-
+  session sweep is an index lookup instead of a full-table scan on the
+  writer. Applies automatically on first start; no operator action needed.
+- **protocol:** no wire changes — `docs/protocol-schema.json`,
+  `message_types.go` and `protocolTypes.ts` are byte-identical to
+  `v1.2.0-alpha.2`. Older clients and servers interoperate unchanged.
+- **fix(ws):** the LiveKit health check shared the process-wide
+  `http.DefaultTransport` pool with every other user in the server; it now
+  owns a private transport (#1356).
+- **chore:** bug-hunt tooling under `.claude/` (fix pipeline, findings
+  ledger, circuit breaker, single-finder hunt with graph-fed targeting —
+  #1361–#1365, #1373); dependency bumps (OTel 1.45.0, koanf, sqlite,
+  eslint/oxlint/knip/typescript-eslint, tauri-plugin-updater, GitHub
+  Actions; #1353–#1360). No runtime impact.
