-# Codex's v1.18.0.0 review flagged that the existing evals.yml workflow uses

+# Same plan/run/verify model as free-tests.yml: one duration-balanced plan of
+# the curated files, one shard per Windows job, and an aggregate that requires

+# static (file contents and the git revision), so they run on Linux. Packing

-#     spawn('sh',...), or raw /tmp/ paths are excluded by scripts/test-free-shards.ts
-#     --windows-only. They need POSIX-bound surfaces to be ported off shell
-#     primitives before they can run on Windows.
-#   - Run Playwright/browser-backed tests. Browse server bring-up on Windows is
-#     a separate concern (PR #1238 windows-pty-bun-pty-fix is in flight).
+# Native browser qualification campaigns (Windows cookie extraction, launch
+# diagnostics, Dia on macOS) are dispatch-only in native-qualification.yml.

 # Changelog
 
+## [1.91.24.0] - 2026-10-05
+
+**PR evals stop throwing away work, and a red weekly census means something again.**
+**The free suite is faster, its flakes are visible, and broken commands are gone.**
+
+This release is a test, eval and CI audit wave. It touches no skill behavior. The paid PR lane keeps a cancelled run's finished results for the next push, waits briefly when pushes come in quick succession, and runs only the gate cases a change can affect once the change avoids a shared input. Every paid lane has a ceiling sized per runner, so a stuck shard ends as an honest `TIMEOUT` or `not_run` instead of holding a runner for four hours. The weekly census can no longer be cancelled by a branch dispatch, and a new weekly test-health report says which free tests are getting flaky or slow.
+
+### The numbers that matter
+
+| Check | v1.91.22.0 | v1.91.24.0 |
+|---|---|---|
+| Paid CI job ceiling (gate census / periodic) | 254 / 173 min for every slice | 34-82 min per slice; 50 min for ordinary periodic slices |
+| Local `eval:bg:pr` / `eval:bg:release` detach cap | 25.8 h / 32.4 h | 2.9 h / 2.25 h (1.5× planned work, never over 4 h) |
+| Passing results a cancelled PR run hands to the next push | 0 | every finished shard, failures included |
+| A branch dispatch that cancels main's weekly census | possible | no (concurrency is per ref and event) |
+| Windows free lane wall | 8.1 min on one runner | about 4.6 min on six runners |
+| Windows-safe files the curated lane runs | 573 | 638 |
+| zsh arms of the bash+zsh portability tests in CI | ~42 skipped (no zsh) | all run |
+| Free-suite flaky passes reported anywhere | none (a write-only artifact) | job summary + weekly `test:health` |
+| Sentence pins on skill prose in free tests | 2,332 | 1,190 |
+
+### What changes for you
+
+- **PR evals keep finished work.** A `recover-receipts` job restores the passes and failures of up to five cancelled runs of the same PR, checks where each came from, and hands them to the planner, so a re-push re-runs only what changed. A 90-second debounce skips a run that a newer push has already superseded; the `evals-no-debounce` label turns it off and `evals-fresh` turns reuse off.
+- **PR selection narrows where it can.** Duration seeds, free-only workflows, free tests and free fixtures (listed in `test/helpers/free-fixtures-data.ts`) no longer force the full gate. Other files map to the paid cases that actually consume them, derived from imports, bin names, template placeholders and build outputs (`scripts/pr-dependencies.ts`); deleted files are placed the same way. Shared inputs (package.json, the CI image, setup, the preamble resolvers, the eval policy) still run the full gate. The job summary names every fallback file and its fix.
+- **`bun run eval:bg:pr` and friends dispatch CI when your HEAD is clean and pushed**, and otherwise run locally with a cap sized to the planned work. Both paths end with `### gstack-detach EXIT=<code> ###`; `bun run scripts/eval-bg.ts status <log-or-run-id>` reads it.
+- **Weekly test health.** `bun run test:health` (and `.github/workflows/test-health.yml`, Mondays) reports PR-lane fallback rate, reuse, cancelled slice-minutes, flaky free tests over 5% of main runs, and unseeded free tests. Its tracking issue opens only from main.
+- **Branch census dispatches run the periodic lane only.** Add `-f include_gate_census=true` for the gate census too, or dispatch `evals.yml` with `-f evals_all=true` for gate cases alone.
+- **The OSV scan opens a tracking issue when it fails on main**, and a free test fails 14 days before any `ignoreUntil` suppression expires.
+
+### Behavior changes you may notice
+
+- **EVAL_POLICY is v2.** A case's pass-rate history resets only when its own files or the declared `HARNESS_VERSION` change, weeks for quarantine expiry count main runs only, and branch census trials count toward a case's history only when its files match a series main has run. Readers ignore records from a newer policy version and say how many they skipped. Shared-harness edits record a decision with `bun run scripts/bump-harness-version.ts --bump|--non-behavioral "<why>"`.
+- **The 15 `carve-section-loading-<skill>` test files are one case-sharded file** with a case id per skill (`--case carve-section-loading-review`); `GSTACK_CARVE_SKILL` is gone. `skill-e2e-qa-workflow` runs case by case.
+- **Paid slices pack 7 minutes of work (was 9)**, so more runners start at once.
+- **`eval:select` defaults to the PR profile.**
+- **`/cso` docs say contained runtime and scanner runs are not available yet**: no runtime profile is qualified and the scanner catalog is empty.
+
+### For contributors
+
+- These package scripts print their replacement and exit 1 for one release, then go away:
+
+| Retired | Use instead |
+|---|---|
+| `test:evals`, `test:e2e`, `eval:bg` | `bun run eval:bg:pr` |
+| `test:evals:all`, `test:e2e:all`, `eval:bg:all` | `bun run eval:bg:release` |
+| `test:gate` / `test:periodic` | `bun run test:gate:sharded` / `test:periodic:sharded` |
+| `test:codex`, `test:codex:all` | `bun run test:periodic:sharded` (they ran zero cases) |
+| `eval:flake-rank` | `bun run eval:pass-rates` |
+| `eval:watch` | tail the `gstack-detach` log, or `gh run watch <run-id>` |
+| `test:audit` | `bun run test` |
+
+- `docs/test-value-bar.md` narrows a "prompt-byte contract" to machine-read tokens. Check template and SKILL.md structure with `test/helpers/prompt-structure.ts` instead of pinning English sentences.
+- Free-suite tests share one install fixture (copy-on-write clones of a read-only seed) and inject short deadlines instead of waiting real seconds. Subprocess pipe tests use FIFOs; see TESTING_INTERNALS "Flake ledger" for the rules.
+- The free duration seed is shrink-only above 60 seconds per file (`scripts/free-test-seed-allowlist.json`), and only `bun run test:ubicloud --record-durations` produces an acceptable seed. Windows has its own seed, refreshed by a `record_durations` dispatch.
+- Deleted: `ci-image.yml` (the eval workflows build the same image), `scripts/update-readme-throughput.ts`, `scripts/eval-watch.ts`, orphaned fixtures, and ~160 unused imports in the paid runner (now split into `scripts/lib/paid-types.ts` and `paid-select.ts`). Native Windows and Dia qualification moved to the dispatch-only `native-qualification.yml`; ML, gitleaks and Swift opt-in tests run in the quarterly `platform-qualification.yml`. Small CI jobs run on free GitHub-hosted runners.
+- Evidence, the EVAL_POLICY v2 memo and its backtest are in [docs/test-audit-2026-10.md](docs/test-audit-2026-10.md).

+`scripts/eval-bg.ts`, which prints `[eval-bg] backend=<dispatch|local> …` and
+`gstack-detach LOG <path>`, then returns immediately.
+
+- **Dispatch backend** (default when HEAD is clean and pushed to garrytan/gstack
+  and `gh` can dispatch): CI runs the lane on the pushed revision (`evals.yml`
+  and/or `evals-periodic.yml`, verified by `expected_sha`); the local log follows
+  the run and names its URL. Dispatched runs are validation runs: fresh, never
+  writing PR receipts. Commit and push first; uncommitted files or unpushed
+  commits fall back to local and the log says why.
+- **Local backend** (dirty tree, unpushed commits, a fork, no `gh`, or `--local`):
+  the sharded runner on this machine, capped at ceil(1.5 × planned serial seconds
+  / EVALS_JOBS) + 20 min, at most 4 h (`--timeout SECS` overrides). Export
+  `ANTHROPIC_API_KEY` first (never pass keys in argv).
+- **Forcing**: `--dispatch` refuses with the fix ("commit and push, or rerun with
+  --local") instead of falling back; `--local` or `GSTACK_EVAL_BG_MODE=local`
+  always runs here.
+- **Waiting**: poll the log until `### gstack-detach EXIT=<code> ###` (0 passed,
+  1 failed, 130 cancelled, 2 other); silence is not success. Keep checking until
+  it appears or the user tells you to stop, and report progress at each check.
+  `bun run scripts/eval-bg.ts status <log-or-run-id>` prints running, passed,
+  failed, cancelled or incomplete (died without a sentinel).
+- Both backends hold the machine-wide `gstack-evals` lock, so concurrent
+  worktrees queue instead of saturating the API; logs live under
+  `~/.gstack-dev/eval-runs/`. A second `eval:bg:<lane>` for the same revision and
+  base follows the queued, running or green dispatch instead of dispatching again.

 ### CI
 
 A GitHub Action (`.github/workflows/skill-docs.yml`) generates all hosts on pushes to main and on PRs, then rejects tracked differences and nonignored untracked output. Generation errors also fail the job. Optional ignored host caches are not compared against Git.
 
 Supply-chain gates run alongside it:
 
-- **Quality gate** (`.github/workflows/quality-gate.yml`, every PR and push) — scans the diff's added lines for credentials using gstack's own redact engine (`.github/scripts/gate-secret-scan.mjs`). HIGH findings fail the job; MEDIUM findings surface as an advisory count. Fails closed if the scan can't produce a report. Also gates critical dependency advisories and runs ShellCheck on the setup/build boundaries.
-- **Dependency review** (`.github/workflows/dependency-review.yml`) — reviews dependency changes on PRs that touch lockfiles or workflow files.
-- **OSV scanner** (`.github/workflows/osv-scanner.yml`) — weekly vulnerability scan against the OSV database. Config lives in `.osv-scanner.toml` and is loaded via an explicit `--config` flag (OSV does not auto-discover that filename); every ignore entry needs a reason and an `ignoreUntil` expiry, enforced by `test/osv-config-wiring.test.ts`.
+- **Quality gate** (`.github/workflows/quality-gate.yml`, every PR and push) — scans the diff's added lines for credentials using gstack's own redact engine (`.github/scripts/gate-secret-scan.mjs`). HIGH findings fail the job; MEDIUM findings surface as an advisory count. Fails closed if the scan can't produce a report. Also runs ShellCheck on the setup/build boundaries.
+- **Dependency review** (`.github/workflows/dependency-review.yml`) — reviews dependency changes on PRs that touch `package.json` or `bun.lock` files and fails on high or critical advisories. It and the weekly OSV scan are the dependency gates.
+- **OSV scanner** (`.github/workflows/osv-scanner.yml`) — weekly vulnerability scan against the OSV database. Config lives in `.osv-scanner.toml` and is loaded via an explicit `--config` flag (OSV does not auto-discover that filename); every ignore entry needs a reason and an `ignoreUntil` expiry, enforced by `test/osv-config-wiring.test.ts`. A failed main scan upserts the tracking issue "OSV scanner: vulnerable dependency needs triage" and a clean scan closes it; `test/osv-ignore-expiry.test.ts` fails 14 days before any `ignoreUntil`, so an expiring suppression surfaces in a PR.
+- **Weekly test health** (`.github/workflows/test-health.yml`, Mondays and on dispatch) — runs `bun run test:health --since-days 7 --enforce`. It fails when a free test file flakes in more than 5% of at least 20 main runs or more than 5 free files are missing from the duration seed, upserts one tracking issue on failure and closes it only when every previously failing check has evidence and passes. Metrics it cannot read print "unavailable: <reason>; next: <step>" and never fail the run.
 - **Dependabot** (`.github/dependabot.yml`) — grouped dependency update PRs.
 - **OpenSSF Scorecard** (`.github/workflows/scorecard.yml`) — weekly and on main pushes; results in the Security tab and api.scorecard.dev.
 
+- **Platform qualification** (`.github/workflows/platform-qualification.yml`, dispatch and quarterly) — runs the opt-in tests no other lane has prerequisites for: the ML prompt-injection classifier (`SECURITY_BENCH=1`), memory ingest against real gitleaks (`GSTACK_TEST_GITLEAKS`), and the DebugBridge Swift build (`GSTACK_TEST_SWIFT=1`, macOS). `test/platform-qualification-workflow.test.ts` pins each gate to its job.
+
 Every workflow pins its third-party actions to commit SHAs (`test/workflow-action-pins.test.ts`). The PR template (`.github/PULL_REQUEST_TEMPLATE.md`) asks for evidence — tests run, eval output — not promises.
 
 Tests run against the browse binary directly — they don't require dev mode. Anything that needs Aside itself (`test/skill-e2e-aside.test.ts`, the Aside qa/design cases, the live render in `test/aside-render.test.ts`) runs only on a Mac with the Aside app open and self-skips elsewhere; make-pdf's render gates and the `/diagram` E2E run on whichever engine resolves, so CI runs them on the browse binary it builds with `bun run build:gates`.

+PR selection (`scripts/test-pr-profile.ts`) classifies every changed file. A file
+mapped by a paid case's touchfiles selects that case. These files are exempt and
+select nothing: docs, any non-paid `*.test.ts(x)`, `FREE_ONLY_PR_FILES` (the

+paid evals, and free-only tools), and the fixtures in `FREE_FIXTURES`
+(`test/helpers/free-fixtures-data.ts`, each fixture with its free consumers).
+`PAID_WORKFLOW_FILES` (`evals.yml`, `evals-periodic.yml`, `evals-marathon.yml`)
+and any other unknown file restore the full gate (`prCoverage.mode =
+full-fallback`). The job summary and PR comment list each file that caused a
+fallback with one of three labels:
+
+- **needs touchfile entry**: a paid test, helper or fixture no case maps; add it
+  to the owning case in `E2E_TOUCHFILES` (`test/helpers/touchfiles-data.ts`).
+- **add to FREE_ONLY_PR_FILES**: a file only free lanes read; add it to the list
+  in `scripts/test-pr-profile.ts` (or a fixture to `FREE_FIXTURES`).
+- **real unknown dependency**: shared code (bin/, lib/, resolvers, hosts, setup)
+  whose dependents are not mapped; the full gate is the correct result.
+
+`test/free-fixtures.test.ts` holds the inventory: each `test/fixtures/**` path
+belongs to a paid touchfile or `FREE_FIXTURES`, and each workflow to the paid or

+their Bun test is named by the case id; the file's other cases stay deferred with
+a reason that says to name the test by its case id.
+
+### PR receipts, recovery and debounce
+
+Passes and failures of single-trial shards are written as receipts at the
+execution boundary, so a cancelled run's finished work survives. The
+`recover-receipts` job runs `scripts/recover-receipts.ts` from the base ref with
+`actions: read`: it merges the receipts of at most 5 completed, cancelled
+`evals.yml` runs of the same PR (oldest first, negatives before passes, so a newer
+FAIL blocks an older PASS) and hands the store to `plan-slices`, which keeps
+`contents: read` only. Its `recovery.json` checkpoint never advances past an
+unresolved run. `plan-slices` turns reuse off when recovery degraded, the
+checkpoint is missing or a cancelled run is still unresolved; recovery itself
+never fails the run, and the job summary names the reason (rate limit with its
+reset time, `gh auth status`, the 60-second budget). The whole store is saved by
+`slices-report`.
+
+On a `synchronize` push, when another run for the same PR started in the last 15
+minutes, the debounce job waits 90 seconds before planning; a run that outlives
+the wait reports "superseded by <sha>". PR labels: `evals-no-debounce` skips the
+wait and `evals-fresh` turns receipt reuse off. Labels apply from the next push,

+Free-suite flake rules:
+
+- Bun gives a child `stdio: 'pipe'` a unix socketpair. A test that must hold a
+  write blocked uses a FIFO the test never reads (`test/qa-evidence.test.ts`,
+  `test/qa-deadline.test.ts`), not a paused child stream: socket capacity follows
+  `net.core.{w,r}mem_default` and the parent's reader.
+- A test that rewrites CI provenance variables (`CI`, `GITHUB_*`, `CI_*`)
+  restores them. Free shards run many files in one process, and a later browse
+  daemon without `CI=true` launches Chromium sandboxed.
+- Handshakes with a runner wait for the runner's own observable effect (its
+  progress line, a coalesced read count), not for a fixture side file or a timer.
+
+### Free suite duration seed
+
+`scripts/free-test-durations.json` drives shard packing; files missing from it
+pack at the seed's 99th percentile. Acceptable seeds come from
+`bun run test:ubicloud --record-durations` (each file timed in its own child on a
+VM with the CI lane's environment) or a CI recording. A 4-core laptop or
+small-sandbox recording is not acceptable: browser and display tests skip or slow
+down there, so the seed misstates them.
+
+- `--ci-plan` warns in the job summary, with the refresh command, when more than 5
+  files are unseeded; it never fails a PR. `--ci-verify` lists shards that ran
+  longer than 1.5× their prediction and at least 30 seconds over.
+- The weekly test-health run fails its enforced `unseeded-free-files` check
+  ("stale seed: N unseeded file(s) > 5") when more than 5 free test files are
+  missing from the seed, so contributors without Ubicloud access learn within a
+  week that it needs a refresh.
+- `test/free-seed-ratchet.test.ts` (run with full history in `free-tests.yml`'s
+  `free-plan` job, `GSTACK_FREE_SEED_BASE=$(git merge-base HEAD origin/main)`)
+  fails when a seeded file over 60 seconds is missing from
+  `scripts/free-test-seed-allowlist.json`, when an allowlist entry is stale (gone,
+  or no longer over 60 seconds), or when an entry is added relative to the
+  merge-base copy without a `todo`. An annotated exception is
+  `{file, reason, todo}` and the test prints it. A merge-base without the

+### Windows free lane
+
+`windows-free-tests.yml` plans on Linux (`--windows-only --ci-plan --shards 6`),

+`gh workflow run windows-free-tests.yml --ref <branch> -f record_durations=true`,
+then download the `free-test-durations-windows` artifact and commit it.
+
+Curation lives in `scripts/lib/windows-curation.ts`. Every Windows plan and
+`--list` prints the curated count and the top exclusion reasons (also in the job
+summary). Files a probe proved safe despite a `/tmp` literal are force-included
+(`WINDOWS_PROBE_SAFE`). `test/windows-native-workflows.test.ts` holds
+`WINDOWS_CURATED_FLOOR`; when Windows-safe tests are deleted on purpose, lower it
+in the same PR with a reason.
+

+```
+
+### Real-setup install fixture
+
+Tests that run the real `setup` use `test/helpers/install-fixture.ts`. Each test
+file builds one read-only seed checkout and clones it per test with
+copy-on-write file copies (plain copy fallback), never hard links. Writes go
+through `put`, `setVersion` and the `fixture*Sync` helpers; files register
+`afterEach(cleanupFixtures)` and `afterAll(cleanupSeed)`.
+`test/install-fixture.test.ts` is the isolation tripwire: writes in one clone
+leave the seed and sibling clones unchanged.
+
+### Test-only timing knobs
+
+Defaults are the product's; tests shrink them instead of waiting real time:
+`GSTACK_RENDER_SLACK_MS` (`lib/aside-render.ts`, default 10000),
+`GSTACK_MEMORABLE_LOCK_TRIES` (`bin/gstack-memorable`, default 50 tries of 0.1 s),
+the `recordGraceMs` option of `test/helpers/office-hours-attempt.ts` (default

+## Corrections (2026-10 audit)
+
+Facts above that no longer hold, checked against main at v1.91.19.0:
+
+- `codex-e2e-recommendation-substance` is not census-only: it is no longer in
+  `PERIODIC_CI_EXCLUDE` and runs in every periodic census.
+- The after-metrics are superseded. Five days after release the free suite had
+  regrown by 132 test files and about 53% of serial time; the
+  [2026-10 audit](test-audit-2026-10.md) carries current numbers.
+- The duration seed again lacked 19 files, including the 115-second
+  `claude-overlay-setup.test.ts`, which the planner packed as a short file.
+- `browse/test/compare-board.test.ts` stayed quarantined through this audit; its
+  16 tests now pass headless and run in the free suite again.
+- `ci-image-tag-binding` now pins `evals.yml`, `evals-periodic.yml` and
+  `evals-marathon.yml`; `ci-image.yml` is deleted because those workflows push
+  the same content-hash tag.
+- The weak literal pins listed under Lane 5 are still present.

+# Test, eval and CI audit — October 2026
+
+This document records the evidence behind the October 2026 test, eval and CI
+wave: the EVAL_POLICY v2 decision memo (D1) with its pre-registered backtest,
+and the commands that reproduce every number. Metrics that need post-merge
+traffic are measured with `bun run test:health --since-days 7` (merge + 7 days)
+and `bun run test:health --since-days 28` (after the fourth scheduled census).
+
+## EVAL_POLICY v2 decision memo (D1)
+
+### Why the census is red
+
+The weekly census is red by arithmetic, not by a handful of broken tests.
+Over 22 censuses with trial outcomes the periodic lane recorded 76 failed
+trials in 3,550 (about 3.5 failed trials per run) and the gate census 27 in
+2,241 (about 1.2 per run). With independent failures, P(green) is e^-3.5 ≈ 3%
+for the periodic lane and e^-1.2 ≈ 30% for the gate census; observed green
+rates were 0/22 and 8/22. Holding a ~190-case single-trial lane green 80% of
+the time needs every case at or below about 0.12% failure per run, which a
+live agent judged by one trial does not reach. Fixing the top five chronic
+cases leaves the lane red.
+
+Three levers stay inside the no-retry, no-threshold, no-rejudge rule: make
+detectors deterministic over structured artifacts (W3), classify INFRA
+honestly (W2d, owned by the reliability follow-ups), and make quarantine
+reachable for detector, harness and model-latency failures. v2 targets the
+third lever.
+
+`test:health` reports the census as three separate numbers, so a policy
+change cannot read as a reliability gain: the raw trial failure rate per kind
+and failure class, P(lane red) from pooled per-case rates under the recorded
+panels, and the same evidence re-aggregated with every case judged on one
+trial. Both red probabilities treat every observed failure as
+nondeterminism, so they are upper bounds for known-good inputs.
+
+**False-blocking targets.** Periodic lane: at most 1.0 expected failed trial
+per census (P(red) ≤ 63%) at the 28-day check; gate census: at most 0.5
+(P(red) ≤ 39%). Neither target may be reached by a threshold, retry or
+rejudge change. A miss opens a P1 TODOS entry with the per-kind,
+per-failure-class breakdown from `test:health`.
+
+### What v2 changes
+
+- **Series identity (W4a, CEO-27, ENG-3).** A case's pass-rate series is keyed
+  by the bytes it owns plus `HARNESS_VERSION`: its paid test file, its
+  fixtures, and the prompt files of the skills it names (templates, sections,
+  manifests and the generated `SKILL.md` the model reads). The series key adds
+  the model id, the pinned Claude Code CLI version and the policy version.
+  Shared helpers no longer start new series. Every trial also records the
+  full consumed-input fingerprint (all touchfiles, globals included) as
+  `series_fingerprint`, plus `harness_version`, as provenance.
+  (`caseSeriesIdentitiesV2` in `scripts/eval-trial-series.ts`.)
+- **Harness guard.** `scripts/harness-version.json` pins the blob of every
+  shared execution-harness file: `GLOBAL_TOUCHFILES` plus the session runners,
+  the PTY harness, the e2e gate and the LLM judge (36 files). A free test
+  (`test/harness-version.test.ts`) fails when one changes without a decision.
+  `bun run scripts/bump-harness-version.ts --bump "<reason>"` raises
+  `HARNESS_VERSION` and starts a new series for every case;
+  `--non-behavioral "<reason>"` records the new blobs as compatible with no
+  reset. Entries are one line per file so concurrent PRs that touch different
+  files merge cleanly; on a conflict, take the higher version, then rerun.
+- **Weekly history (W4b).** Weeks for quarantine expiry and drift are
+  `evals-periodic.yml` runs on `main`: scheduled runs and main dispatches.
+  Trials from branch census runs in the same window pool into a series `main`
+  has also run (option (b) below, approved 2026-10-05); a branch identity
+  `main` has not run is dropped and never becomes the current series.
+- **Kinds (W4c).** No kind changes; see the evidence below.
+- **Pre-v2 evidence does not qualify.** Readers segment strictly by
+  `policy_version`: only v2 trials count toward the quarantine entry rule; v1
+  trials stay visible as display-only. Quarantine is not seeded at merge; a
+  case enters only after it reaches `entry.minTrials` qualifying v2 trials,
+  and `test:health` shows qualifying-vs-required counts with "insufficient
+  evidence" distinct from healthy (DX-12).
+
+### W4c: the named "stochastic" cases are deterministic in the record
+
+Recorded census and PR trials (all 95 recorded revisions, October 2026):
+
+| Case | Kind | Passed / trials | Failures |
+|---|---|---|---|
+| plan-ceo-finding-floor | rule | 26/27 | 1 timeout (608 s) |
+| plan-devex-finding-floor | rule | 27/27 | — |
+| plan-eng-finding-floor | rule | 9/9 | — |
+| plan-design-finding-floor | rule | 9/9 | — |
+| plan-ceo-review-plan-mode | rule | 34/34 | — |
+| plan-devex-review-plan-mode | rule | 27/27 | — |
+| plan-eng-review-plan-mode | rule | 9/9 | — |
+
+The comments calling `plan-*-finding-floor` "stochastic ask-first" are stale:
+the record shows these cases behave like rules. AGENTS.md forbids changing a
+kind without pass-rate evidence, and a 3-trial panel would triple their cost
+for no measurable gain, so they stay `rule`. `plan-design-review-plan-mode`
+(17/22) is handled by its detector repair, not by a kind change.
+
+### Backtest (ENG-3, DX-12)
+
+`bun run scripts/eval-trial-series.ts --backtest --weeks 30 --records <dir>`
+replays identities with today's registry over historical trees (cases whose
+test file did not exist at a revision are absent there).
+
+**Weekly main revisions** (29 Mondays, 06:00 UTC, 2026-03-16 to 2026-09-28).
+A case qualifies at a week when one identity holds long enough to collect 10
+trials within the last 10 weekly runs (rule and judge cases record one trial
+per run, behavior cases a panel of three):
+
+| Identity | Qualifying at the latest week | Mean qualifying share, last 8 weeks | Median identity changes per case |
+|---|---|---|---|
+| v1 (own touchfiles minus globals) | 0/195 | 0.3% | 15 |
+| v2 (case-owned bytes) | 0/195 | 0.7% | 14 |
+| v2, reset on every pinned-harness change | 0/195 | 0.1% | 14 |
+| v2 without the generated `SKILL.md` (prototype) | 0/217 | 2.0% | 7 |
+
+**Recorded trials** re-keyed by the v2 identity of the revision that produced
+them (blocking cases with at least 10 trials on one series):
+
+| Trial source | Recorded (v1) identity | v2 identity |
+|---|---|---|
+| 22 census runs (5,665 trials) | 52/210 | 67/210 |
+| Census + PR lane, 95 revisions (14,898 trials) | 107/210 | 134/210 |
+
+**Harness churn.** The pinned harness changed in 24 of 28 consecutive-week
+transitions, and 33 of the last 60 main commits (2026-08-04 to 2026-10-04)
+touched a pinned file. About half of PRs therefore record a
+`bump-harness-version` decision, and only `--bump` decisions reset series.
+
+### What the backtest shows
+
+1. v2 makes series honest and longer when trials are dense: on the recorded
+   census runs, 67 blocking cases reach 10 trials on one series versus 52
+   under v1, and 134 versus 107 with PR-lane trials included.
+2. Under the approved weekly history (main scheduled runs plus main
+   dispatches, about one run per week), no blocking case reaches 10
+   qualifying trials at any recent week. A rule case needs ten consecutive
+   weekly runs on unchanged owned bytes, and a case's own prompt files
+   change about every two weeks (the generated `SKILL.md` carries the shared
+   preamble). Excluding the generated `SKILL.md` halves identity churn but
+   still qualifies at most 2% of cases, and it would let preamble and resolver
+   prompt changes pool unless every such edit went through the harness guard.
+3. So v2 alone does not make quarantine reachable. Reaching it needs one of:
+   (a) keep the history as approved and accept that quarantine stays rare, so
+   census redness is fixed at source (W3) and tracked by `test:health`;
+   (b) pool trials from every v2 census run whose series key matches,
+   including branch dispatches, while weeks for expiry still count from main
+   only — the recorded backtest's 67/210, at the cost of pooling branch code
+   whose unbumped harness edits match; or (c) extra census dispatches on an
+   unchanged main revision (about $175 recorded each). Garry approved (b) on
+   2026-10-05, and this PR implements it: pooled branch trials count only
+   toward a series a `main` run also has.
+
+### Alternatives considered
+
+- **Gating vs trended.** The native CEO voice proposed keeping live-agent
+  cases trended (reported, never blocking) and gating only on deterministic
+  detectors. v2 keeps the census blocking because quarantine and the
+  pass-rate gate already provide a trended path per case; the
+  false-blocking targets above are the check on that choice. If the 28-day
+  check misses them, trended reporting for the remaining stochastic cases is
+  the next proposal.
+- **Adaptive sequential panels** (one trial, escalate to three on a failure,
+  about 1.04× cost across ~190 cases) would be the strongest lever for a
+  green census. They are not adopted: an escalation triggered by a failure is
+  a retry, which Garry's rule forbids.
+- **Buy vs build.** Hosted eval platforms (Braintrust, LangSmith, Weights &
+  Biases Weave) store per-case pass-rate history and cost natively, but
+  gstack's verdicts are produced inside GitHub Actions from Claude Code
+  sessions with pre-registered panels and receipts, and the history is a few
+  thousand JSONL lines per week that `gh` already serves. A platform would add
+  an external dependency and a second source of truth for verdicts without
+  removing the in-repo policy. Building on the existing artifacts stays the
+  choice; revisit if history outgrows artifact retention (90 days).
+
+### Rollout and rollback (ENG-14, DX-12)
+
+The reader-compatibility commit lands first: readers score only trials under
+their own `EVAL_POLICY.version`, show older-policy trials as display-only,
+and ignore newer-policy trials with a printed count. The v2 writer (identity
+stamping and `version: 2`) lands last. The supported rollback is reverting
+the v2 writer commits; a whole-PR revert is not claimed safe.
+
+On a mixed v1/v2 fixture (10 passing v1 trials, 12 v2 trials with 3
+failures), the pre-PR reader at 2db0b3a pools the v2 records as the current
+v1 series and fails its gate:
+
+```
+pass-rates: policy v1, 22 post-policy trial(s), 0 pre-policy (display only)
+  FAILING       rule      gate      9/12 [46.8%–91.1%]  ...  plan-ceo-review-plan-mode  (baseline reset)
+ACTION REQUIRED (2): [drift] ... [rule-as-behavior] ...
+exit=1
+```
+
+The compatibility reader ignores the v2 records and keeps the v1 series:
+
+```
+pass-rates: policy v1, 10 post-policy trial(s), 0 pre-policy (display only)
+  ignored 12 trial(s) recorded under a policy newer than v1: this checkout predates them. Fix: ...
+  PASSING       rule      gate      10/10 [72.2%–100%]  ...  plan-ceo-review-plan-mode
+exit=0
+```
+
+## Wave evidence
+
+### PR paid lane selection replay (CEO-23, ENG-18)
+
+The replay sends each recorded PR push's changed files through today's
+selector and dependency graph:
+
+```bash
+gh run list -R garrytan/gstack --workflow evals.yml --json databaseId,headSha,event,createdAt,conclusion -L 200 > runs.json
+bun run scripts/replay-pr-selection.ts --runs runs.json
+```
+
+Over 168 PR pushes with plan manifests (2026-09-25 to 2026-10-04):
+
+| Measure | Recorded | Replayed |
+|---|---:|---:|
+| Full-fallback pushes | 165 of 168 (98.2%) | 164 of 168 (97.6%) |
+| Misses (a failed case that depends on the diff and is no longer selected) | — | 0 |
+| Failed cases that no longer exist (counted apart) | — | 6 |
+
+113 of the 168 diffs exceed the compare API's 300-file cap and are replayed on
+their first 300 files. The rate barely moves because the replay uses each push's
+cumulative branch diff, and the wave branches of that week touch shared inputs
+that correctly select every case: `scripts/` in 156 pushes, `.github/` in 125
+(mostly the eval workflows), `bin/` in 120, `make-pdf/` in 90, `test/helpers/` in
+86, `design/` in 67, `lib/` in 58, `hosts/` in 56 and `tsconfig*.json` in 37. The
+selector removes the single-class fallbacks (duration seeds, free-only workflows,
+`scripts/ubicloud/**`, free tests and free fixtures; run 36497566037 now selects
+the `pr` profile) and cannot narrow a branch that changes `bin/` or `lib/`;
+narrowing those needs touchfile mappings for `bin/`, `lib/`, `hosts/` and
+`make-pdf/`. The post-merge `test:health` check measures the fallback rate on
+ordinary PRs.
+
+### Paid slices and concurrency (ENG-17)
+
+Live census with `EVALS_ALL=1` (periodic: `--list --slice-budget S --jobs 2`;
+gate census: `--emit-plan <file> --slice-budget S --jobs 2 --skip-judges`):
+
+| Lane | Before (540 s) | After (420 s) |
+|---|---|---|
+| Periodic slices / peak shard processes | 26 / 52 | 33 / 66 (max-parallel 26 → 36) |
+| Weekly gate census slices / peak | 12 / 24 | 16 / 32 (max-parallel 16 → 20) |
+| CI job ceiling | One value for every slice: 173 min periodic, 254 min gate census | Per slice: ordinary 50 min (30-minute shard wall + 20), periodic outliers 52 and 73 min, the overlay slice 173 min (5 serialized overlay wrappers); gate census 34–82 min |
+
+The PR lane (`evals.yml`) uses the same 420-second budget and per-slice ceilings.
+
+### Free suite
+
+- The Windows lane runs on six `windows-latest` jobs packed by Windows-measured
+  durations: about 4.6 minutes wall in the free-suite branch's validation runs,
+  down from 8.1 minutes on one runner.
+- Unseeded files pack at the 99th percentile (was the 75th), and the seed growth
+  ratchet (`test/free-seed-ratchet.test.ts`) keeps files over 60 seconds on a
+  shrink-only allowlist.
+- The bash+zsh portability tests (#2669) run in CI now that the free-suite job
+  installs zsh.
+- Native Windows and Dia qualification campaigns moved out of the PR workflow
+  into the dispatch-only `native-qualification.yml`.
+
+### Prose pins (D2)
+
+D2 is approved: the prompt-byte contract in
+[test-value-bar.md](test-value-bar.md) covers machine-read tokens only, and
+sentence pins in 55 free test files became structural checks through
+`test/helpers/prompt-structure.ts`. A sentence pin here is a 40-or-more-character
+English string literal, or a prose regex of five or more words, asserted against
+SKILL.md, template or section text in a free test.
+
+| Measure | main (2db0b3a) | This wave |
+|---|---:|---:|
+| Sentence pins | 2,332 in 217 files | 1,190 in 209 files |
+| Shouting pins (NEVER/MUST/ALWAYS/CRITICAL emphasis) | 8 | 4 |
+
+The 4 remaining shouting pins are enum or marker tokens (`PLAN MODE EXCEPTION —
+ALWAYS RUN`, `[CRITICAL]`, `ALWAYS-ON` CLI output), not emphasis. Most remaining
+sentence pins sit in QA caller, detector-helper and workflow files that other
+work in flight owns.

+ *
+ * A case consumes the transitive reference closure of its owning paid test
+ * file plus every tracked file its touchfiles declare. References are:
+ *   - static and literal dynamic imports of code (resolved relative paths);
+ *   - repository paths written in code, shell or skill text (bin/, lib/,
+ *     scripts/, browse/, design/, make-pdf/, hosts/, test/helpers/ ...),
+ *     including `path.join(..., 'lib', 'x.ts')` segments;
+ *   - bin script names (`gstack-*`) a skill, test or script invokes;
+ *   - compiled binaries (scripts/build.sh `--outfile`): text naming
+ *     `design/dist/design` consumes the whole `design/src/**` tree;
+ *   - package scripts invoked as `bun run <name>`;
+ *   - template placeholders: a skill whose template uses `{{NAME}}` consumes
+ *     the resolver module behind RESOLVERS.NAME and that module's imports;
+ *   - host configs: `hosts/<id>.ts` and `hosts/<id>/**` feed cases whose test
+ *     names that host id.
+ * Selection data modules are opaque (their literals classify files rather
+ * than consume them), and the walk never enters another paid test file.
+ *
+ * A file the derivation cannot place is not guessed: PR selection restores
+ * the full gate for it (scripts/test-pr-profile.ts), and PR_FULL_GATE_FILES
+ * there lists the inputs every case consumes that must always do so.

+ * reports, per push, the recorded mode and case count against the new mode
+ * and case count, the gate cases the new selector no longer runs, and every
+ * MISS: a case that actually failed in that run, still exists, and depends
+ * on the diff (today's touchfiles), yet is not selected now. Acceptance is
+ * zero misses. The replay uses today's dependency graph (ENG-18): cases that
+ * no longer exist are counted separately, never as misses.
+ *
+ * Inputs come from GitHub with `gh` (read-only): each run's `paid-plan`
+ * manifest, its trial-outcomes artifact, and the three-dot compare of the
+ * merge-base with the run's head SHA. Downloads are cached under --cache.

+ * test:health — the audit's success metrics as one command, read from CI
+ * history (scripts/lib/ci-history.ts, the same reader pass-rates uses) plus
+ * the local tree. Every metric prints its counting rule; a metric whose input
+ * cannot be read prints "unavailable: <reason>; next: <step>", never 0.
+ *
+ * Enforced checks (`--enforce`): a free test file that flakes in more than 5%
+ * of main free-tests runs over a window of at least 20 runs (W7a), and more
+ * than 5 free test files missing from scripts/free-test-durations.json
+ * (CEO-10). Without `--enforce` the command always exits 0; an unavailable
+ * check never fails it. Needs `gh` with read access to the repository.
+ *
+ * Usage:
+ *   bun run test:health [--since-days 7] [--json] [--enforce] [--summary <file>]
+ *                       [--repo owner/name] [--complexity-base <ref>]
+ *   bun run test:health flake-summary <dir>   # job-summary table of downloaded flake-ledger-* artifacts

 /**
- * test-paid-shards — enumerate, shard, and run the paid (gate/periodic) tier.
+ * test-paid-shards — enumerate, shard, plan and run the paid (gate/periodic/marathon) tiers.
  *
- * The single-process `test:gate` fan-out has never completed a run: one wedged
- * or spinning file takes the whole tier down, and an in-process `--timeout`
- * cannot save it because a spinning main thread never fires a timer. This
- * runner applies the free tier's proven fix — one Bun process per shard — plus
- * the two things the paid tier additionally needs:
+ * Every paid test file (or case, or trial) runs in its own Bun process with an
+ * EXTERNAL wall-clock timeout that kills the shard's process GROUP, so a wedged
+ * file or a surviving `claude`/`codex` PTY grandchild never takes a run down or
+ * outlives it. Each shard gets its own GSTACK_EVAL_DIR, TMPDIR and Chromium
+ * profile. The aggregate distinguishes passed, failed, timed-out, never-started
+ * and skipped-by-diff, so partial execution can never look like a pass.
  *
- *   - an EXTERNAL wall-clock timeout that kills the shard's process GROUP, and
- *   - an aggregate that distinguishes failed from timed-out from never-started,
- *     so 26% execution can never again look like a pass.
+ * Modes:
+ *   --emit-plan   PLANNER: select once (tier, diff/PR profile, exclusions) and
+ *                 pack shards into slices by recorded duration
+ *                 (scripts/paid-test-durations.json); each slice gets its own CI
+ *                 job ceiling (scripts/lib/paid-plan.ts sliceCiTimeoutMinutes).
+ *   --plan/--slice EXECUTOR: run one slice of that manifest, stop starting work at
+ *                 the slice deadline (job ceiling minus a 5-minute upload
+ *                 reserve: not_run), kill in-flight shards there (hung), and
+ *                 checkpoint the slice result after every shard.
+ *   --report      REPORT: reconcile slice results against the manifest,
+ *                 fail-closed (a missing slice is a failure, not an absence).
+ *   (none)        local run of a whole tier; --list previews the plan.
+ *   --case        local diagnosis of one case through the CI panel runner.
  *
- * Why not Bun 1.3.13's native `--shard` / isolated runs? Three gaps, each one
- * fatal for this tier:
- *   1. No detached-process-group SIGKILL. Paid tests spawn `claude` / `codex`
- *      PTY grandchildren; when a shard hangs, in-process isolation kills the
- *      Bun worker but the grandchildren survive and burn cores for hours.
- *   2. No never-started taxonomy. A run that aborts partway reports only what
- *      executed — the shards that never ran are invisible, which is exactly
- *      the 26%-execution-looks-like-a-pass bug.
- *   3. No per-shard env / eval dir. Each shard needs its own GSTACK_EVAL_DIR
- *      so eval baselines are per-test-file instead of last-flush-wins.
+ * Background local runs and CI dispatch go through scripts/eval-bg.ts
+ * (`bun run eval:bg:<lane>`), which caps a local run at
+ * ceil(1.5 x planned serial seconds / EVALS_JOBS) + 20 min, at most 4 h.
  *
- * Worst-case wall clock = ceil(shards / jobs) × shard timeout. Shard counts
- * drift as test files land, so treat any number written here as stale.
- * Do NOT hand-derive the eval:bg:* detach timeouts from a snapshot of
- * these counts — test/eval-detach-timeout-floor.test.ts recomputes the bound
- * from the live shard census every run and fails CI if package.json's numbers
- * dip below it (undersized detach timeouts recreate never-started truncation).
+ * Env contract: EVALS_JOBS = how many shard PROCESSES run at once.
+ * EVALS_CONCURRENCY = bun's --max-concurrency WITHIN a shard. Exporting 15 as
+ * the shard count would start 15 claude-spawning processes (the 429 storm).
  *
- * Env contract: EVALS_JOBS = how many shard PROCESSES run at once (this
- * runner). EVALS_CONCURRENCY = bun's --max-concurrency WITHIN a shard (and the
- * legacy single-process scripts). They were previously conflated: exporting
- * the legacy value 15 gave you 15 concurrent Bun processes each spawning
- * claude — the 429 storm.
+ * Enumeration uses test/helpers/paid-test-set.ts and honors EVALS_TIER against
+ * E2E_TIERS (test/helpers/touchfiles.ts). Spawn, kill, sandbox, logs, seeds and
+ * output classification come from scripts/lib/shard-engine.ts; selection and
+ * planning live in scripts/lib/paid-{types,select,cases,plan,report}.ts; this
+ * file keeps the runner and the CLI.
  *
- * Enumeration matches package.json's `test:gate` globs (via the shared
- * test/helpers/paid-test-set.ts) and honors EVALS_TIER against the E2E_TIERS
- * map in test/helpers/touchfiles.ts. Spawn, kill, sandbox, logs, seeds and
- * output classification come from the shared shard engine
- * (scripts/lib/shard-engine.ts); this file keeps only paid-lane policy.
- *
- * Parallelism now lives ACROSS shards (--jobs), not inside one Bun process, so
- * each shard runs its own file sequentially and can be killed independently.
- *
- * Usage:
- *   bun run scripts/test-paid-shards.ts --list                # shard plan only
- *   bun run scripts/test-paid-shards.ts --tier gate           # run gate tier
- *   bun run scripts/test-paid-shards.ts --timeout 600 --jobs 2
+ * Usage: bun run scripts/test-paid-shards.ts --help

- * Detach-timeout floor — free, gate-tier tripwire.

  *
- * The eval:bg:gate / eval:bg:periodic scripts wrap the sharded paid runner in
- * bin/gstack-detach with a hard --timeout. If that number dips below the
- * runner's worst-case wall clock — ordinary waves plus registered excess — the
- * watchdog kills a healthy run mid-flight and the tail shards report
- * never-started: paid truncation by configuration. That nearly shipped once
- * (a review pass proposed 10800s against a 19,800s gate worst case), so the
- * bound is enforced here against the LIVE shard census instead of a comment
- * snapshot that goes stale every time a paid test file is added.
- *
- * If this test fails you have two honest options: raise the --timeout in the
- * package.json script it names, or reduce the tier's worst case (split fewer
- * files per shard, raise DEFAULT_JOBS after verifying API rate headroom).
+ * The old contract made multi-hour detach walls legitimate (a 26 h eval:bg:pr
+ * floor sized for every shard at its worst case). The contract now:
+ *   - every eval:bg:<lane> script runs `scripts/eval-bg.ts <lane>`, never a
+ *     literal --timeout;
+ *   - local cap = ceil(1.5 x planned serial seconds / EVALS_JOBS) + 20 min,
+ *     at most 4 h (--timeout overrides);
+ *   - dispatch only from a clean HEAD pushed to garrytan/gstack with gh able
+ *     to dispatch; otherwise local with the reason, or a refusal under --dispatch;
+ *   - both backends run under bin/gstack-detach with the gstack-evals lock and
+ *     end with the `### gstack-detach EXIT=<code> ###` sentinel; a followed CI
+ *     run maps success 0, failure 1, cancelled 130, other 2.

Three panels: `QuickActions` (links into existing workflows from the action registry's three actions, filtered by server-side eligibility), `NotificationsPanel` (member-specific alerts with persistent read state, latest first), `ActivityFeed` (immutable audit history of workspace changes, latest first).\n- One new read endpoint `GET /api/dashboard` composing existing repository methods; member and workspace IDs come from the existing session and membership middleware, never from the request. No schema change, no new mutation API.\n- \"Mark all as read\" uses the existing member-scoped, idempotent bulk-read API, which marks notifications created at or before a supplied snapshot time. It opens a confirmation dialog built on the existing dialog primitive.\n- Toast feedback for actions; per-panel loading skeleton, empty, error, and success states; Tailwind, mobile-first at sm/md/lg; hover and focus-visible on every control; accessibility policy (named controls, live region, contrast, reduced motion).\n- Existing test stack: Vitest, React Testing Library, Playwright; fixtures for authenticated member, other workspace, empty lists, service failures.\n- Out of scope by the user: dark mode; personalization/customization; action ranking; a configuration service.\n- Limitation of this review: the repository under review contains no application code (fixture), so every \"existing\" contract above is taken from the plan text. Two facts that depend on code are resolved as the first implementation step (see Accepted Scope, \"Code-dependent checks\").\n\n## Vision\n\n### 10x Check\nThe dashboard becomes the member's \"what's next\" home: ranked next-best actions drawn from the action registry, live unread counts visible in the shell on every page, real-time updates for alerts and changes, and a per-member layout. Concrete shape: a ranking service over the existing eligibility predicates, an SSE or WebSocket channel, a shell badge, saved panel order. This plan lands the page, the instrumentation that proves or kills it, and two shared primitives (`AsyncPanel`, `Toast`) that the 10x version reuses. Ranking, configuration, personalization, and real-time are explicitly separate work.\n\n### Platonic Ideal\nNot produced (SELECTIVE EXPANSION mode).\n\n## Scope Decisions\n\n| # | Proposal | Effort | Decision | Reasoning |\n|---|----------|--------|----------|-----------|\n| E1 | Per-panel result envelope + `generatedAt` + `unreadCount` in the aggregate response | S | ACCEPTED | Correctness: partial failure isolation; total unread drives the heading and the dialog copy |\n| E2 | Shared `AsyncPanel` presentational wrapper used by all three panels, fed by one page-level fetch coordinator | S | ACCEPTED | One state machine instead of three copies; one fetch, so retry cannot cancel sibling panels |\n| E3 | Toast as a shared app-level primitive with one live region, mounted once at the app root | S | ACCEPTED | A11y policy requires a live region anyway; page-local would be duplicated. The app-root mount is a one-line edit to the existing shell and is in blast radius because the page requires it |\n| E4 | Empty states with a next step | S | ACCEPTED | In blast radius, minutes of work |\n| E5 | Notification rows link to target when the model provides one | S | ACCEPTED with fallback | If the existing notification model exposes no target, rows render as non-linking text (code-dependent check) |\n| E6 | Refetch after mark-all-read + stale-response guard | S | ACCEPTED | Async schedule shows a stale overwrite without it |\n| E7 | Row-shaped skeletons, reduced-motion aware | S | ACCEPTED | Policy requirement |\n| E8 | \"View all\" links to existing full pages | S | ACCEPTED | Reuses existing pagination pages |\n| E9 | Pull production baseline from existing analytics before rollout | S | ACCEPTED | The 75s figure is from a team walkthrough; the real events exist |\n| E10 | Numeric guardrail thresholds, sample-size rule, hold criterion, kill rule, named fallback experiment | S | ACCEPTED | Rollout criteria are in the plan's own \"must be specified\" list |\n| E11 | Unread count badge in the existing shell nav on every page | S | DEFERRED | A new query plus new UI on every page of the app; not required by the dashboard |\n| E12 | Manual refresh + last-updated | S | DEFERRED | Not required by any state |\n| E13 | Keyboard shortcuts for quick actions | S | SKIPPED | Unearned complexity; existing shortcut conflicts unknown |\n| E14 | Optimistic UI for mark-all-read | S | SKIPPED | Pessimistic flow is explicit and the API is fast |\n| E15 | Real-time updates (SSE/WebSocket) | L | DEFERRED | New infrastructure |\n| E16 | Action ranking / personalization | \u2014 | REJECTED | Explicitly out of scope in the user's plan |\n\n## Accepted Scope (added to this plan)\n- **Endpoint shape.** `GET /api/dashboard` runs the activity read, the notification read (items plus total unread count), and the eligible-action evaluation in parallel, each time-boxed at 800ms. Response: `{ generatedAt, activity, notifications, quickActions }`, each panel a `PanelResult<T> = { ok: true, data } | { ok: false, error: { code: 'unavailable' | 'timeout' } }`; `notifications.data = { items, unreadCount }`. There is no per-panel `forbidden` code: membership is gated once by the existing middleware in this single-role workspace. `generatedAt` is the server time at response assembly. The endpoint returns HTTP 200 for any authenticated workspace member, including when all three panels are `ok: false`; 401 and 403 come from the existing middleware. Lists are capped at 10 rows, created-at descending.\n- **Fetch ownership.** `UserDashboard` owns one coordinator hook, `useDashboardData`, that calls the endpoint, tags each request with a sequence number, aborts the in-flight request when a new one starts, discards responses older than the latest, and exposes per-panel `PanelResult` plus `retryingPanel`. `AsyncPanel` is presentational: it receives a result, a loading flag, an empty state, and `onRetry`.\n- **Retry.** Panel Retry asks the coordinator to refetch with that panel's id. Only that panel shows loading. Panels already in success or empty update in place without a skeleton. Panels still failing stay in error. A panel that was ok and comes back `ok: false` keeps its last good data and shows an inline \"Couldn't refresh\" note with Retry.\n- **Toast.** Shared `ToastProvider`/`useToast` mounted once at the app root: one `role=\"status\"` `aria-live=\"polite\"` region, at most 3 visible with queueing, 5s auto-dismiss paused on hover or focus, no motion under reduced motion. Toasts carry no interactive controls (WCAG 2.2.1 timing); anything needing an action is shown inline.\n- **Mark all as read.** Button disabled with explanatory text when `unreadCount` is 0. Dialog copy: \"Mark N notifications as read?\" with N = `unreadCount`. Confirm disabled while submitting. The request sends `generatedAt` as the bulk-read snapshot time, so notifications created after the dashboard response stay unread. Outcomes: success \u2192 dialog closes, notifications refetch through the coordinator, toast \"N notifications marked as read\". 401 \u2192 dialog closes; the existing unauthenticated handling redirects to login. 403 \u2192 dialog closes, toast \"You don't have permission to do that\", notifications refetch (membership may have changed). 5xx or network \u2192 dialog stays open with an inline `role=\"alert\"` message \"Couldn't mark notifications as read. Try again.\" and Confirm serves as retry; no toast, no refetch. Escape or cancel returns focus to the trigger.\n- **Copy and layout.** Empty states with a next step (\"Nothing to do right now\"; \"You're all caught up\"; \"No recent changes yet\", linking to the first eligible action only when the quick-actions panel is ok and non-empty, otherwise plain text); \"View all\" links; relative timestamps with full time in `title`; unread count in the Notifications heading; panel order Quick actions, Notifications, Activity; stacked at sm, actions strip plus two columns at md/lg.\n- **Landing redirect and bucketing.** Flag `dashboard_landing` is evaluated server-side in the existing post-login redirect handler with sticky member-level bucketing (hash of member id against the cohort percentage), so a member stays in the same arm for the whole rollout. Cohort members are redirected to `/dashboard` with history replace; control members go to the current landing page unchanged. A route guard sends direct visits to `/dashboard` by non-cohort members back to the current landing page.\n- **Code-dependent checks (first implementation step, recorded in the PR description).** (a) Whether an existing unread-count method exists; if not, add one member+workspace-scoped count query on the existing indexed table (no schema change). (b) Whether the notification model exposes a route target; if yes, rows link to it; if no, rows render as non-linking text.\n- **Baseline pull (before the 5% step).** From existing analytics: median login-to-first-completed-task, defined as login event to first action-completion event in the same session, segmented by the first action-start event's action id (the \"first intent\"; if a first page-visit dimension exists, segment by that too), plus eligible-action counts per member.\n- **Rollout ladder.** Deploy endpoint; deploy frontend with flag off; staging smoke (authenticated GET 200 with three ok panels; unauthenticated 401); then cohort 5% \u2192 25% \u2192 100%, at least 2 business days per step, guardrails checked daily, each step evaluated only once both arms have at least 500 sessions.\n- **Guardrails** (defaults, confirmed against the baseline; all cohort vs concurrent control cohort, never vs the 75s walkthrough): completed-task rate (sessions with at least one action-completion \u00f7 sessions) not more than 2% relative below control; permission-error rate (sessions with at least one permission-error event on an action-start \u00f7 sessions) not more than 0.5 percentage points above control; total `GET /api/dashboard` latency p95 under 1s (staging target 300ms; the 800ms per-read time-box sits below the 1s total guardrail).\n- **Hold criterion.** After at least one week at 25% with at least 500 sessions per arm, the cohort's median login-to-first-completed-task must be at least 15s better than control; otherwise hold the rollout at 25% and review.\n- **Kill rule.** If the shortfall is unexplained after review, set `dashboard_landing` off for all cohorts (the page stays deployed but unreachable) and run the pre-registered smart-default routing experiment next. Rollback at any step is flag off.\n\n## Kept as specified (subagent disagreed; taste decisions for the final gate)\n- Aggregate endpoint rather than three per-resource requests (T1).\n- Confirmation modal on \"Mark all as read\", because no undo/mark-unread API exists (T2).\n- Activity feed stays in v1 (T3).\n- Toast kept, as a shared primitive rather than page-local or cut (T4).\n\n## Deferred to TODOS.md\n- Shell unread badge (P2): surfaces alerts on every page; add if cohort data shows members leave before triaging. Depends on dashboard analytics.\n- Manual refresh + last-updated (P3): superseded by real-time if that ships.\n- Real-time dashboard updates (P3): SSE/WebSocket; depends on the metric being validated first.\n- Smart-default landing route experiment (P2, pre-registered as the kill fallback): route members to their most likely destination after login; depends on the baseline segmented by first intent.\n",

- * Real-setup fixtures for the install conformance kit (test/host-conformance.test.ts)

+ * Real-setup fixtures for the install tests: host conformance, the install
+ * registry, the Claude overlay, Conductor hooks and Codex scope.
  *
  * A fixture is a throwaway gstack checkout (the working tree's tracked and
  * untracked-but-not-ignored files, so uncommitted changes are under test) plus
  * a clean HOME. Binaries are stubbed and `bun run build` is refused, so setup
  * runs its real registration path without compiling (GSTACK_SKIP_PLAYWRIGHT,
  * GSTACK_SETUP_SKIP_CSO_BUILD, GSTACK_SKIP_FONTS). Every write the test makes
- * goes through `put`, which refuses paths outside the fixture root.
+ * goes through `put` or the `fixture*Sync` wrappers, which refuse paths
+ * outside the fixture roots.
+ *
+ * The checkout is built once per test file into a read-only seed and cloned
+ * per fixture (copy-on-write reflink/clonefile where the filesystem has one,
+ * else a full copy). Clones are independent files, never hard links, because
+ * tests and `put` write into the checkout in place.

 Delivery throughout this non-interactive run: keep chat to brief progress and actual decision acknowledgements. Write the complete diagnostic, premise challenge, alternatives, independent opinion and rationale into the design instead of first publishing a separate walkthrough in chat. After design approval, write the full relationship closing and handoff directly into REPORT.md. These file writes deliver the required content; do not narrate it in full and then transcribe it again.
 Completion delivery, after the full workflow and design approval:
 1. Compose REPORT.md as a completion record: summarize each phase's outcome and actual decisions with their rationale, and link the approved design and saved review evidence. The design retains the detailed diagnostic, alternatives, and independent opinion; do not replay those as a second transcript. Include the full actual Assignment, coaching/relationship closing, approval outcome, and Handoff, including the user's declined downstream launch. This changes delivery only; complete every required phase and preserve all findings.
