Garry TanandClaude Fable 5 e76f65a8da v1.77.0.0 feat: test-infrastructure overhaul wave 1 — matrix deletion, flake telemetry, sync-spawn wedge class extinct (#2746)
* fix: pin the claude CLI to an exact version in the CI image + tripwire

The image installed @anthropic-ai/claude-code UNPINNED and rebuilt weekly
'to pick up CLI updates' — while bun sat carefully pinned at 1.3.13 two RUN
lines above. The PTY harness screen-scrapes this CLI's TUI, and that drift
broke it three separate times (welcome-screen wedge on 2.1.233, skillify
HOME discovery on 2.1.237, guard/freeze hooks on 2.1.162), each debugged as
a flake first. Pin 2.1.251 (current latest), bump deliberately via a PR
that runs the PTY gate, and enforce with test/ci-image-cli-pin.test.ts:
any global npm install in Dockerfile.ci without an exact @X.Y.Z pin fails
the free suite. The weekly ci-image cron stays as a cheap tag self-heal.

* feat: stamp the claude CLI version into every eval-store run record

Three harness breakages were traced to claude-CLI TUI drift only after long
flake hunts, because no run record said which CLI it actually exercised.
EvalCollector now stamps claude_cli_version (claude --version, cached once
per process, 'unknown' when the binary is absent) into both partial and
finalized records — schema-additive optional field, no SCHEMA_VERSION bump.
Correlating a flake wave with a CLI release becomes a grep over
~/.gstack/projects/<slug>/evals/ instead of archaeology.

* fix: give the spinning-shard kill test load headroom (30s -> 90s)

The test spawns and group-kills three real children (one a busy-loop
burning a full core) while five sibling shard processes compete for eight
vCPUs. Under full-suite load it blew bun's default 30s per-test ceiling at
30,009ms — while passing in isolation in 1.4s — and red the only required
lane. Every assertion in it is event-based (statuses, group-kill proof,
heartbeat lines); the sole latency claim is the <30s kill-deadline sanity
bound, which stays. Explicit 90s headroom, not a weakened oracle.

* feat: green-by-skip census — skip counts in the classifier, all-skipped labeling in the paid runner

bun's 'Ran N tests' line COUNTS skipped tests, so a codex/gemini shard
whose every test self-skipped (binary absent on the runner — true of every
CI runner today) exits 0, dodges the hollow-shard guard, and reads as
coverage in the weekly census. The classifier now parses bun's ' N skip' /
' N pass' recap lines; ShardOutcome carries skippedTests; formatSummary and
the fail-closed slices report label an all-skipped pass explicitly:
'all N tests SKIPPED — verified nothing'. Status stays 'passed' (external
service availability is host state, not a repo regression) but the census
can no longer mistake absence for coverage.

* refactor: extract composite actions for eval-lane setup; surviving lanes gain the fail-fast registry verification

'Fix bun temp' x3, 'Restore deps' x5, 'Seed claude interactive config' x3,
and 'Register gstack skills' x3 were byte-near-identical copies across the
legacy matrix, the sliced lane, and the periodic lane — and only the MATRIX
copy of register-skills carried the 19-line dangling-symlink + frontmatter
fail-fast loop written after a silent 'Unknown command' + 35-min-timeout
incident. Extract all four into .github/actions/ composites; the register
composite carries the verification loop (generalized over the skill list),
so the sliced and periodic lanes — the lanes that SURVIVE the matrix
deletion — now inherit the check they had silently dropped. Matrix-job
inline copies are left untouched: that job is deleted next.

* feat: delete the legacy 17-row eval matrix — the sliced lane is the only paid lane

Every PR paid twice: the hand-enumerated matrix (18 test files, 22.6 min,
~$21 API measured on run 33263204465) ran serialized AHEAD of the strictly
superior sliced lane via 'needs: evals' — 35.5 min wall and ~2x paid spend
for the same diff. 14 of 17 rows carried no tier:, so periodic Opus
benchmarks leaked into every PR (the e2e-plan row alone: 12/12 tests,
21.7 min, $7.28 — the wall-clock bound of ALL of CI).

Parity receipt (static, pre-deletion): the sliced lane's gate census (49
files, derived from the runner itself) strictly contains all 18 matrix test
files, plus 31 files the matrix never ran. Pure deletion — one revert
restores it. The PR comment moved into slices-report (same '## E2E Evals'
upsert marker, now sourced from slice artifacts + carrying the fail-closed
reconciliation verdict). plan-slices loses the needs edge; the dead
workflow-level EVALS_TIER env goes with it.

test/evals-workflow-matrix.test.ts (and its KNOWN_MATRIX_GAPS /
KNOWN_TIER_UNSET burn-down ratchets — retired: the sliced census makes
'every gate file runs' true by construction) is rewritten as
test/evals-workflow-wiring.test.ts: matrix stays deleted, planner/executor/
report tier + slice-count agreement, both surviving lanes on the shared
register-skills composite with its fail-fast verification loop, PR comment
survival. Expected: PR eval wall 35.5 -> ~13 min, per-PR paid spend ~halved.

* fix: provider-runner timeouts kill the whole process GROUP; codex/gemini inherit the orphan-drain hardening

All three provider runners (claude/codex/gemini) killed only the direct
child on timeout: tool subprocesses the CLI spawned survived as orphans
holding our pipes open and burning shared API rate (observed: a 600s
timeout stretching past 1400s; a stalled run once burned a core for 15
hours). gstack-detach's watchdog had the same shape one level up — killpg
SIGTERM, 5s grace, then a direct-child proc.kill() that orphaned
grandchildren.

Fix: spawn provider children via node:child_process with detached (own
process group) and killProcessGroup(SIGKILL) in the timeout handler —
runShardChild's proven pattern, EPERM/ESRCH fallbacks included. The codex
and gemini copies also gain the reader.cancel() + stderr Promise.race
hardening only the claude copy had (they still carried the blocked-drain
hang it fixed). gstack-detach's watchdog now group-SIGKILLs after the
grace.

Regression net: test/session-runner-groupkill.test.ts drives the REAL
runSkillTest against a fake claude shim (PATH override) that spawns a
grandchild and wedges — the run must classify timeout within budget and
leave neither shim nor grandchild alive — plus source pins on all three
runners (detached + killProcessGroup, no bare timeout kill, no Bun.spawn
reversion).

* fix: skill-e2e-opus-47 renders SKILL.md fixtures into a mkdtemp — never the live tree

mkEvalRoot ran gen-skill-docs with cwd=ROOT, regenerating every in-repo
SKILL.md mid-run while concurrent paid shards copyFileSync those same files
in their beforeAll (EVALS_JOBS>=4 locally, 2 per CI slice) — a sibling
could capture a half-regenerated or opus-rendered SKILL.md, and a timeout
before afterAll stranded the whole tree at the wrong model for every later
shard. A cross-shard race that could flake ANY concurrent paid test.

Render via the --out-dir flag gen-skill-docs grew for exactly this reason
(mirrors the repo layout, which is all the fixture reads), read the skill
heads from the render dir, delete it, and drop the afterAll restore-regen
entirely.

* fix: claude CLI version resolves in the runner parent, never on a test thread

Eng-review finding: getClaudeCliVersion's fallback is a SYNCHRONOUS
spawnSync on the same thread that polls concurrent PTY/session tests — the
judgePtyState blocking class this overhaul kills elsewhere. The paid runner
parent now resolves it once (cached) and stamps GSTACK_CLAUDE_CLI_VERSION
into every shard's env; eval-store short-circuits on the env var, and the
fallback spawn's budget tightens 10s -> 3s (bounded one-time stall, records
'unknown' on a slow CLI).

* test: wire skippedTests end-to-end through runPaidShard

The census unit tests hand-built outcomes and the classifier tests parsed
strings; nothing proved a real child's ' N skip' recap flows into
outcome.skippedTests and the formatSummary label. A commandFor fake now
prints the recap shape and the test asserts the parsed counts, the
all-skipped predicate, and the 'verified nothing' label.

* fix: make the setup composites rerun-safe (codex diff-review hardenings)

restore-deps: 'cp -r SRC node_modules' with an existing node_modules NESTS
the copy and leaves stale deps active — rm first. register-gstack-skills:
'ln -snf' hard-errors under set -eu when a REAL directory occupies the
gstack slot — clear a non-symlink leftover first. CI workspaces are fresh
today; a reusable composite must survive dirty reruns.

* fix: sweep — every sync spawn in the test trees carries a timeout (436 sites, 157 files)

spawnSync/execSync/Bun.spawnSync BLOCK the main thread, so bun's in-process
per-test timeout can never fire while one waits — a hung child (stdin read,
network probe, dead daemon) wedges the whole shard until the runner's
external wall-clock SIGKILL. This exact class reached main: free-tests run
33262077256, test/gstack-memory-ingest.test.ts (normally 2.3s) held shard 2
at the 360s wall while its five siblings finished in ~65s.

Mechanical sweep in two waves (12 + 4 fan-out agents, every edit verified
against its call site): default timeout: 30_000 (matches the free runner's
per-test budget), 120_000 for genuinely slow ops (installs, builds,
playwright, provider CLIs), helper wrappers fixed ONCE where call sites
route through them. Sites that only LOOK like calls (string fixtures, grep
needles, comments) were skipped with reasons — the enforcement commit that
follows marks them exempt.

* test: sync-spawn timeout tripwire — the wedge class stays extinct

Free scanner over all test trees (test/, browse/test/, design/test/,
make-pdf/test/, ios-qa, browser-skills): every spawnSync/execSync/
Bun.spawnSync call site must carry a timeout within a 30-line options
window, or an explicit '// tripwire-exempt: <reason>' marker. Comment
lines are skipped; exemptions are counted and ratcheted shrink-only
(ceiling 6 = the 6 string-fixture/grep-needle sites where the pattern is
CONTENT, not a call — marked in this commit). A scan-sanity test pins that
the scanner still sees >100 real call sites so it can never rot to a
vacuous green. Companion to the 436-site sweep in the previous commit.

* feat: paid-lane flake telemetry — record-level attempts, flaky_retries, report surfacing

bun --retry leaves a retried pass INVISIBLE in its output: a fail-then-pass
prints the error detail but no (fail) result line and recaps as a clean
pass (probed live on 1.3.10). So attempts are recorded where they cannot
lie: EvalCollector.addTest stamps a 1-based attempt on same-name re-records
(a retried test runs its body again and re-records), finalized runs carry
flaky_retries, printSummary warns loudly, and the fail-closed slices report
lists every passed-only-on-retry test — recorded and ranked, never blocking
and never silent. Cross-model confirmed (codex reached the same don't-parse
-the-stream conclusion independently).

* feat: free-lane flake ledger — retry ON in CI, flaky-passes recorded and uploaded

The runner's attribution-gated flaky-retry pass (cap 5, truncation veto)
was OFF in the required lane and its FLAKY-PASS evidence was console-only —
so a single timing flake red the merge gate while repeat offenders stayed
unenumerable. free-tests.yml now sets GSTACK_FREE_RETRY_FLAKY=1 and points
GSTACK_FLAKE_LEDGER at runner.temp; every flaky-pass appends a JSONL entry
(SINGLE writer: the parent runner — no concurrent-append hazard by
construction; fail-open with a loud warning so a broken ledger can never
red the lane) and the artifact uploads UNCONDITIONALLY — a flaky-pass run
is green, which is exactly when the evidence matters. Wiring pinned by
free-tests-workflow-wiring; ledger behavior unit-tested incl. the fail-open
path. Matches 2026 industry practice (retry for data, quarantine out of
merge-blocking but never out of logging) with the repo's own receipts.

* feat: eval:flake-rank — the flake-telemetry dial

Aggregates per-test series across every finalized eval-store run (shard
dirs included) plus the free flake ledger: runs, fails, RETRIED PASSES
(the flake signature), avg duration — ranked retries-first. This is the
readable dial behind two policies: a flaky pass never blocks a merge but
is always ranked here, and the WS16 required-check promotion needs weeks
of clean flake-rank, not vibes. --json for machines, --dir for downloaded
CI artifacts.

* feat: two-phase session timeout — silent APIs die at the startup grace, named

The single spawn-armed timer charged API queue latency to the work budget:
the recurring '0 turns / $0.00 / x3 attempts' failure with four budget-bump
receipts (180->300s, 240->360s, 300->420s, 90->300s). Split: startup phase
(no NDJSON byte yet) kills EARLY at min(grace, timeout) with the distinct
exitReason 'timeout_startup' — an availability verdict, not transcript
archaeology — and the work phase arms on the first byte for the REMAINING
budget, so total wall never exceeds the timeout (tier envelopes are
margin-free: tests pass timeout: CAPTURE_MS and bun-budget the same tier).
Local grace 90s (observed queue latency 60-90s), CI floor 300s (TODOS-filed;
shared runners queue harder), both pinned by the new grace tests with fake
-claude shims covering the late-first-byte and silent-API paths.

* fix: census integrity — 17 phantom selection keys deleted, reverse invariant added, gitignored dep patterns replaced, local map forks derived

The merge-blocking gate census counted tests that could not run. Deleted
(critic-verified against both quoted-occurrence and dep-registration
liveness): 7 *-prosons-format keys with no declaring test, ship-plan-
completion/-verification, review-plan-completion, design-shotgun-path/
session/full, autoplan-core (dead ~10 months), e2e-harness-audit (its
namesake is a FREE-suite file), plus 2 dead LLM-judge keys and 2 free-file
keys (budget-regression-pty, global-discover) misplaced in the PAID maps.
Census: 191 -> 174 keys, gate 86 -> 78 honest.

The new reverse invariant in touchfiles.test.ts makes the class structurally
impossible: every key must be quoted in a living paid test file OR
registered to an existing paid test file via its dep list (the constructed-
name binding the 2026-08 self-registration sweep established) — zero
exceptions needed today, with a live-file check on any future exception.

Also: '.agents/skills/**' dep patterns replaced with the generator
(scripts/gen-skill-docs.ts) — .agents/ is gitignored, so those patterns
could NEVER match a git diff and review-template edits silently stopped
selecting codex/gemini tests; the codex/gemini local touchfile maps are now
DERIVED from the canonical map (loud throw if a key vanishes) instead of
hand-forked copies that had already drifted. ios-qa-e2e demoted gate ->
periodic: its gate declaration was never executable in CI (hardware
exclusion only applies at tier=periodic), so every Linux PR planned a
hollow shard.

* fix: routing journeys lose their answer key and end at the routing decision

The journey tests exist to catch skill-DESCRIPTION regressions (touchfiles:
*/SKILL.md.tmpl), but the fixture CLAUDE.md shipped an explicit
prompt->skill lookup table — with the answer key in context, a badly
regressed frontmatter description still routed correctly, so the tests
could not fail on the exact class they select for. The fixture now carries
only the generic invoke-skills nudge; the frontmatter carries the routing
load. Also capped all 10 journeys at maxTurns 2 / tools [Skill, Read]:
only the FIRST Skill call is asserted, so 5 turns of Read/Bash/Glob/Grep
was pure spend — roughly halves each journey's cost.

* fix: retire decided A/B experiments; vendor the pre-cut fixture; ban raw-SHA fixtures

Three one-shot decision experiments kept re-running weekly as N=1
stochastic comparisons — flaky by construction with near-zero remaining
information: skill-e2e-auq-repetition-cut-ab (its own header: gate "passed
pre-landing, approved 2026-08-25"), skill-e2e-preamble-script-ab ("demoted
post-Phase-3"), and opus-47's fanout arm-vs-arm (parA >= parB across two
SINGLE stochastic runs — a coin flip). Deleted, with their selection keys;
the SDK overlay-harness stays as the maintained instrument for the next
experiment, and opus-47 keeps its routing-precision cases.

verboseSkill() now reads the VENDORED test/fixtures/auq-pre-cut-...-SKILL.md
instead of `git show ab66193e^:...` — a branch-local ref that dies on
branch prune and already failed on shallow clones. New free tripwire
(test/git-ref-fixture-tripwire.test.ts) bans the raw-SHA fixture class
outright: quoted SHA:path rev-specs and gitRef-style hex defaults in the
test trees fail the suite with the vendor-instead instruction.

* fix: demote plan-ceo-review-expansion-energy to periodic

Opus generator + a subjective 2-axis >=4/5 LLM-judge threshold sat in the
MERGE-BLOCKING gate — the exact class its sibling posture tests were
demoted for, with a receipt (a +21-line preamble change once flipped the
score). CLAUDE.md's own tiering rule: Opus model test -> periodic. The
weekly lane keeps the regression signal; merges stop paying a judge-
temperament tax.

* fix: paid shards get per-shard TMPDIR + CHROMIUM_PROFILE isolation and a kill-path cleanup backstop

The free runner treats this isolation as MANDATORY (two concurrent shards
on one Chromium profile kill each other's browser; shared tmp
cross-contaminates) — the paid lane had none of it. Doubly load-bearing
here: a shard that hits its 30-min wall is group-SIGKILLed, so per-test
afterAll cleanup never runs; the rmSync backstop is the only thing keeping
wedged runs from accumulating full git-repo workspaces in the shared
tmpdir forever. This is the DAG prerequisite for raising EVALS_JOBS (next
commit) — more concurrency on shared state amplifies exactly the
shared-tree race class opus-47 exhibited.

* feat: paid-runner defaults 4x4 -> 8x2 — halve the local gate worst case

39 of 75 skill-e2e files hold exactly ONE test, so within-shard
concurrency was dead weight for most shards: 4 jobs x 4 concurrency
yielded only ~4-6 real in-flight sessions and a 13-wave local gate worst
case (~6.5h). 8 jobs x 2 gives ~10-13 in-flight — under the
documented-safe ~15 — and ~7 waves (~3.3h worst case). CI lanes keep
their explicit EVALS_JOBS env (2 per slice; 4 for gate-census); this
changes local defaults. Rollback trigger: sustained 429 storms in the WS1
telemetry across 2 PR cycles. test/eval-detach-timeout-floor.test.ts
recomputed green (the raise LOWERS the worst-case floor).

* fix: SHA-pin every action in the secrets-bearing eval lanes

evals.yml and evals-periodic.yml execute PR-authored code with three
provider API keys in env, yet rode mutable action tags (@v7/@v8/@v2/@v4)
— while quality-gate.yml, osv-scanner.yml, and dependency-review.yml
already model the SHA-pin pattern. All 30 uses sites across both lanes now
pin the exact commit (tag noted in a trailing comment); dependabot's
github-actions ecosystem keeps them fresh via PRs instead of silent tag
moves. Pulled forward from the plan's endgame on the CEO-review + outside-
voice agreement: supply-chain pins on secret lanes go first, not last.

* fix: sweep wave 3 — the execFileSync family gets timeouts (90 sites, 17 files)

The tripwire's regex covered spawnSync/execSync/Bun.spawnSync but not
execFileSync — an entire blocking sync-spawn API family that could
reintroduce the shard-wedge class undetected (ship review army). Same
mechanical recipe as waves 1-2: timeout: 30_000 default, 120_000 for slow
ops, shared wrappers fixed once, string-needle sites skipped with reasons.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* test: review-army + adversarial test hardening

- Tripwire scans execFileSync too (ceiling 8: two more grep-needle string
  exemptions); merge-introduced timeout-less spawnSync in
  question-preference-hook fixed — the tripwire caught a site that landed
  on main AFTER the sweep, on its first day.
- gstack-detach gains TWO watchdog kill regression tests: TERM-immune
  grandchild (the killpg-after-grace escalation) and the leader-dies
  variant (the pgid-at-spawn fix — the case the first test cannot see).
- eval-flake-rank gets its unit suite (final-attempt accounting, artifact
  exclusion, shard recursion, recency bound).
- Groupkill/startup-grace shim markers are per-run unique (pid-suffixed
  sleep durations): sibling Conductor worktrees run free suites with no
  machine lock, and fixed markers let one run pgrep/pkill the other's
  shims — a cross-run flake inside the anti-flake tests.
- flake-ledger test pins the project-scoped local default; stale empty
  section headers in touchfiles-data deleted (they invited entries under
  deliberately retired categories).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix: adversarial-review runtime fixes across the telemetry + kill paths

- session-runner: exit-labeling keys off 'exit', not 'close' — an orphan
  holding the pipes could relabel a REAL exit (auth failure) as
  'timeout_startup' availability noise; the kill path still always
  group-kills and cancels the reader (labeling and unblocking are separate
  concerns). Work phase arms on a flag, not firstResponseMs===0 (a same-ms
  first byte left the startup timer live all run). The CI startup grace is
  now a real FLOOR (Math.max), matching its name and pinning test.
- gstack-detach: pgid captured AT SPAWN (== child pid under
  start_new_session) — resolving it after the grace raised ESRCH once the
  leader died on SIGTERM, orphaning TERM-immune grandchildren forever.
- test-free-shards: ledger entries carry branch + git_sha (rev-parse split:
  '--abbrev-ref HEAD HEAD' printed the branch twice and recorded it as the
  sha); local ledger default is per-PROJECT, not the machine-global tmpdir.
- eval-flake-rank: per-LINE ledger parse (one torn JSONL line vanished the
  whole series), 60-day recency bound (transcript-bearing files are MBs),
  shared isFinalizedEvalResultFile predicate (the artifact-taxonomy rule
  lived in three places); eval-store exports the predicate and finalize
  stops computing flakyRetries twice; paid-shards cleanup uses async rm
  (a SIGKILLed shard's git-workspace teardown blocked every sibling's
  stream classification on the parent event loop).

* fix: CI trust-boundary + fail-closed repairs (adversarial findings)

- Token/exec separation restored: slices-report (runs PR-authored code:
  bun install + the reconcile runner) drops to contents:read; the PR
  comment moves to a NEW slices-comment job holding the write token with
  ZERO repo code — no checkout, no bun, only downloaded artifacts + jq/gh.
  $GITHUB_ENV/BASH_ENV persistence is job-scoped, so the split is the
  boundary. The matrix-era report job had this property; the consolidation
  had regressed it. Pinned by the wiring test.
- Reconcile exit captured via PIPESTATUS[0] in BOTH lanes: GitHub's default
  run-step shell has no pipefail, so `$?` after `| tee` was tee's exit —
  the fail-closed gate was silently fail-open. Wiring test pins it.
- PR comment: final-attempt accounting restored the dropped COST
  accumulation (the dial read $0 forever), flaky passes render as the
  warning they are (never as failures), and a malformed tests[] artifact
  skips that file instead of aborting the whole comment under bash -e.
- Remaining mutable action tags pinned (free-tests upload-artifact,
  ci-image checkout/docker trio — the image publisher holds packages:write
  and feeds the secret-bearing lanes). restore-deps fallback installs
  --frozen-lockfile; register-gstack-skills validates skill names before
  its rm -rf.

* fix: slices-comment creates the PR comment via REST — the write-token job has no git context

The token/exec split gives slices-comment NO checkout by design, and gh's
pr-comment subcommand resolves the repo FROM git — it died with 'not a git
repository' on PR #2746's first run (the update-existing PATCH path was
already explicit-repo REST and worked). Create now posts through
gh api repos/.../issues/N/comments, and the wiring test pins that no
git-context-requiring comment call can creep back into the job.

* fix: startup-grace probes clear CI for local semantics; new probe pins the floor clamp

The two shim probes pass explicit 2s/4s graces, but in CI the runner clamps
any explicit grace up to the 300s floor (deliberate adversarial-review fix),
so 'silent API killed at the grace' died at the 30s work cap instead of 2s —
a deterministic red on every CI run, green locally. The probes now pin LOCAL
semantics with CI cleared (same save/restore pattern as their PATH shim),
and a fourth probe pins the clamp itself: CI=1 + 2s grace + 6s timeout must
kill at the 6s cap, still in the startup phase — proof an explicit low grace
cannot bypass the floor.

Garry TanandClaude Opus 4.7 920a13a17f v1.44.0.0 feat: long-lived sidebar — keepalive, restart, re-attach, scrollback replay (#1678)
* fix(browse): identity-based terminal-agent kill replaces pkill regex

Commit 0 of the v1.44 long-lived-sidebar PR — foundation for the watchdog
and removes a latent cross-session footgun.

`pkill -f terminal-agent\.ts` (cli.ts spawn site + server.ts shutdown) matched
by argv regex and would kill ANY process whose argv contained the string —
sibling gstack sessions on the same host, an editor with the file open, a
second `$B connect` run. Identity-based PID kill via a new helper module
removes that whole class of bug.

  * New `browse/src/terminal-agent-control.ts`: `readAgentRecord`,
    `writeAgentRecord`, `clearAgentRecord`, `killAgentByRecord`. Validates
    PID liveness via `isProcessAlive` before signaling (PID-reuse defense).
  * `terminal-agent.ts` writes `<stateDir>/terminal-agent-pid` (JSON
    `{pid, gen, startedAt}`) at boot; clears on SIGTERM/SIGINT.
  * New per-boot `CURRENT_GEN` (16-byte random); `/internal/*` callers can
    include `X-Browse-Gen` to defend against split-brain in the upcoming
    watchdog. Absent header is accepted (backward compat); mismatch returns
    409. New `checkInternalAuth` helper centralizes bearer + gen checks.
  * New `/internal/healthz` route — agent liveness probe used by the
    upcoming watchdog (returns pid/gen/sessions, no claude-binary lookup).
  * `cli.ts` and `server.ts` both call `killAgentByRecord` instead of pkill.
  * `ServerConfig.ownsTerminalAgent` JSDoc updated; the gated teardown now
    runs 4 side effects (was 3) — adds the new agent-record unlink.

Test changes:

  * New `browse/test/terminal-agent-pid-identity.test.ts` — static-grep
    tripwire that fails CI if any source file re-introduces `pkill ...
    terminal-agent` or `spawnSync('pkill', ...)`; round-trips
    write/read/clear; verifies killAgentByRecord no-ops on dead PIDs.
  * `browse/test/server-embedder-terminal-port.test.ts` rewritten to
    intercept `process.kill` (not `child_process.spawnSync`); writes a
    sentinel agent-record with a guaranteed-dead PID; asserts probe-only
    (signal 0) calls, no termination signals; verifies all 3 discovery
    files including the new terminal-agent-pid.

Closes TODOS.md P3 ("Identity-based terminal-agent kill").

* fix(tests): repair 7 pre-existing failures (env pollution + stale markers)

All 7 failures existed on main before this branch — verified via `git stash`
round-trip. Bundling them into the long-lived-sidebar PR because we kept
tripping over them while running `bun test` to verify Commit 0.

  * Global afterEach restores `process.env.PATH` (new bunfig.toml +
    test-setup.ts). browser-skill-commands.test.ts sets
    `PATH = '/test/bin:/usr/bin'` to exercise a scrubbed-env fixture and
    used the broken `process.env = origEnv` reassignment pattern that
    swaps the proxy reference; the underlying env stayed mutated and
    leaked downstream. Fixed three call sites in that file and added a
    narrow PATH-only global guardrail so a future polluter can't bring
    the bug back. Killed: pair-agent-tunnel-eval (bun ENOENT),
    security.test.ts > resolveBashBinary (Bun.which('bash') null),
    server-no-import-side-effects (bun ENOENT).
  * server-auth.test.ts: two `sliceBetween` markers referenced strings
    deleted when sidebar-agent.ts was ripped — `'Sidebar agent started'`
    → `'Terminal agent started'`, `'Sidebar endpoints'` → `'Batch endpoint'`.
    Also fixed the pair-agent BROWSE_PARENT_PID assertion (the literal
    `serverEnv.BROWSE_PARENT_PID` never existed in source; the actual
    contract is the object-literal `BROWSE_PARENT_PID: '0'` inside the
    `const serverEnv` declaration).
  * test/upgrade-migration-v1.test.ts: also overrides HOME in the spawn
    env. The migration shells out to `${HOME}/.claude/skills/gstack/bin/gstack-config`
    and a developer's real config with `explain_level` set causes the
    script to take the "user already decided" branch and skip writing
    the pending-prompt flag the test asserts on.
  * test/setup-codesign.test.ts: replaced fragile `bun run build`
    string-match (which hit a comment 700 lines later) with the actual
    invocation `bun_cmd run build` used in the setup script.

Net: full suite is now green; CI no longer trips on bash/bun-ENOENT
from PATH pollution or on test markers that drifted with the codebase.

* refactor(terminal-agent): extract internalHandler<T> helper for /internal/* routes

Replaces the copy-pasted bearer-auth + X-Browse-Gen + req.json().then().catch()
boilerplate on /internal/grant and /internal/revoke with a single
internalHandler<T>(req, fn) wrapper. Future /internal/* routes added by the
v1.44 long-lived-sidebar work (/internal/lease-refresh, /internal/restart)
land as one-liners using the same helper. Pure refactor; no behavior change.

/internal/healthz stays on the bare checkInternalAuth gate because it's a
GET with no JSON body to parse — the helper's body-parse path would 400 it.

  * browse/src/terminal-agent.ts — new internalHandler<T>; /internal/grant
    + /internal/revoke routed through it.
  * browse/test/terminal-agent-internal-handler.test.ts — static-grep
    tripwire that fails CI if the helper goes away or either of the two
    refactored routes regresses to the old inline pattern.

* feat(terminal-agent): 25s WS keepalive ping/pong + client keepalive frames

PTY connections were dying silently after NAT idle timeouts (30-60s on most
home routers, even shorter on some carrier-grade NAT) and Chrome MV3 panel
suspension. Neither side noticed until the user's next keystroke produced
no output. Both sides now drive a 25s keepalive cycle.

Server side (browse/src/terminal-agent.ts):
  * New ws.open handler constructs the PtySession eagerly and starts a
    setInterval that sends `{type:"ping",ts:Date.now()}` every 25s.
    Interval handle stored on session.pingInterval so close() can clear it.
  * PtySession.pingInterval field added; cleared in ws.close before
    disposeSession runs. Prevents timer leak across reconnects.
  * Message handler accepts `{type:"ping"|"pong"|"keepalive"}` silently —
    keepalive frames are a liveness signal at the TCP layer, no state to
    update. Existing resize/tabSwitch/tabState handling unchanged.
  * GSTACK_PTY_KEEPALIVE_INTERVAL_MS env knob (default 25000) lets the
    upcoming e2e tests compress idle assertions without 30s waits.

Client side (extension/sidepanel-terminal.js):
  * Belt-and-suspenders: client also runs a 25s setInterval that sends
    `{type:"keepalive"}`. Defends against Chrome pausing our timers if
    the server-side ping ever gets dropped (rare but possible in MV3).
  * Ping reply: on `{type:"ping",ts}` from the server, immediately send
    `{type:"pong",ts}`. Lets the agent observe round-trip latency for
    free and confirms the channel is bidirectional.
  * Interval cleared in three teardown paths: ws.close handler,
    teardown(), forceRestart(). Three paths exist because the sidebar
    can exit the LIVE state through any of them; all three must clean up
    or we leak timers across reconnects.

Test (browse/test/terminal-agent-keepalive.test.ts):
  * Static-grep tripwires for the 7-point protocol contract: agent has
    a configurable interval, open() starts the ping, close() clears it,
    message handler accepts keepalive vocabulary, client sends keepalive
    + replies pong, and all three client teardown paths clear the timer.
  * Wire-level tests (actually observe a ping after 25s) belong in the
    e2e tier — adding them here would either flake on slow CI or require
    a real Bun.serve listener per test which we don't want to pay for
    in the free tier.

* feat(sidebar): patient tryAutoConnect — poll forever with ascending status, abort only on 401

The 15s give-up message ("Browse server not ready. Reload sidebar to retry.")
fired on every cold start where the daemon took >15s to bind — common on
Conductor workspaces, CI runners, and any system under load. The user
already opened the sidebar; telling them to give up is the wrong default.

Now polls every 2s indefinitely with ascending status messages:
  *   0 - 15s : silent (handles the happy path on a warm laptop)
  *  15 - 60s : "Waiting for browse server..."
  *  60s - 5m : "Still waiting — browse server may be slow to start."
  *      > 5m : "Browse server still not responding after 5 min. Try `$B status`."

Loop aborts on three signals only:
  * state transitions out of IDLE (connect succeeded or user navigated)
  * autoConnectAborted sticky flag set on unrecoverable error
  * the panel itself unloading (browser handles this; pagehide cleanup
    arrives with T8 of the larger plan)

401 from /pty-session sets the sticky flag with a clear "Auth invalid —
reload the sidebar or restart your gstack session." message. Without the
flag, the loop would re-call connect() every 2s and spam the same error;
with it, the user sees the message once and the loop holds. forceRestart()
clears the flag so clicking Restart is the explicit "try again" escape hatch.

Bumped poll interval 200ms → 2000ms — the legacy tight loop burned CPU
for no reason. 2s is plenty fast for a "did the daemon come up yet" check.

* feat(browse): terminal-agent watchdog with PID liveness + crash-loop guard

terminal-agent could die independently of the server — SIGKILL from the OS
OOM killer, an uncaught exception under PTY churn, an external `pkill` from
a sibling debugging session. Pre-v1.44 the sidebar would observe the broken
connection and stay broken until the user reloaded the sidebar. Now a 60s
ticker checks the recorded agent PID and respawns via the shared
spawnTerminalAgent helper when dead.

Identity-based liveness (T4 from the eng review):
  * Uses readAgentRecord + isProcessAlive (signal 0 probe), not a name match.
  * Slow-but-alive agents intentionally fall through — respawning around a
    living agent would create split-brain (two agents writing the port
    file, tokens diverging between them, mystery upgrade 401s).
  * Pairs with the v1.44 generation counter in /internal/* loopback calls:
    if a stale agent does come back to life mid-cycle, its X-Browse-Gen
    no longer matches and the parent's calls 409 cleanly.

Crash-loop guard:
  * 3 respawn attempts inside a rolling 60s window → stop trying. A daemon
    up for a week with one crash a day shouldn't trip the guard.
  * On trip: one-line error to console (`respawn guard tripped`) and the
    watchdog goes dormant. Manual restart via the sidebar Restart button
    is the explicit signal to re-arm (added in Commit 2 of the larger PR).

Shared spawn path (refactor):
  * New spawnTerminalAgent(opts) in terminal-agent-control.ts handles:
    prior-PID cleanup → spawn → record stash. Both the CLI cold-start path
    in cli.ts and the new server.ts watchdog route through it. Removes the
    copy-paste between them; future env wiring lands in one place.

Gated on cfg.ownsTerminalAgent — embedders that pre-launch their own PTY
server (gbrowser phoenix overlay) still own the full lifecycle.

GSTACK_AGENT_WATCHDOG_TICK_MS env knob compresses the 60s tick for e2e
tests without 60s waits per assertion.

Tests:
  * browse/test/terminal-agent-watchdog.test.ts — 7 static-grep tripwires
    for the load-bearing invariants (ownsTerminalAgent gate, PID-based
    liveness, crash-loop guard with window pruning, shutdown cleanup,
    CLI cold-start uses the same helper, env knob exists).
  * Live process-kill tests belong in the e2e tier; cheaper invariants
    here catch refactor regressions in ~1ms each.

* feat(cli): opt-in outer supervisor — respawn browse server on crash

Pre-v1.44 `$B connect` was fire-and-forget: spawn server detached, CLI
exits, server runs unsupervised. If the server crashed (OOM, uncaught
exception, signal kill from a runaway debugger), the user had to notice,
re-run `$B connect`, and resume work. The v1.44 terminal-agent watchdog
recovers from one layer of failure; this commit closes the outer loop.

Opt-in via `--supervise` flag or `BROWSE_SUPERVISE=1` env. Default
behavior is unchanged — every existing caller (Claude Code's Bash tool,
scripts, CI) still gets a prompt return. When the flag is set:

  * CLI stays attached, polls server PID every 30s via readState() +
    isProcessAlive (same identity primitive as the terminal-agent watchdog).
  * On unexpected exit: respawn via the same headed-mode startServer path
    used initially, then re-spawn the terminal-agent so the PTY recovers
    too (otherwise sidebar Restart is the only path back).
  * Crash-loop guard: 5 respawns in a rolling 5-min window → exit 1 with
    a clear error. Window pruning means a long-lived daemon with sporadic
    crashes does NOT trip the guard (otherwise we punish the user for the
    supervisor doing its job).
  * Backoff: 1s, 2s, 4s, 8s, 30s capped. Env-overridable via
    GSTACK_SUPERVISOR_BACKOFF for tests.
  * SIGINT / SIGTERM: clean teardown — signals the supervised server
    before exiting itself. Without this, Ctrl-C leaves an orphaned server.

Out of scope (deferred follow-up): routing the Chromium-disconnect
exit-code-1 path back through this supervisor. The terminal-agent
watchdog already covers the highest-frequency restart case; Chromium
crash recovery joins the queue as its own commit.

Test (browse/test/cli-supervisor.test.ts):
  * 6 static-grep tripwires: opt-in default, signal wiring, crash-loop
    guard with window pruning, backoff schedule env knob, tick interval
    env knob, terminal-agent re-spawn after server respawn.
  * Live respawn tests belong in the e2e tier (real spawn cycles take
    3-8s each; spamming these in the free tier would balloon CI time).

* feat(browse): pty-session-lease registry — stable sessionId + lease lifecycle

Foundation for Commit 2 of the long-lived-sidebar PR. Separates two
concerns that pre-v1.44 were conflated under one token:

  * sessionId — stable, non-secret identifier for a single PTY session.
    Safe to log, safe in URLs, safe in DevTools. Identifies "this terminal,"
    not "you're allowed to use this terminal."
  * lease — server-side bookkeeping that maps sessionId → expiresAt.
    Re-attach within the lease window resumes the same PTY; expiry tears
    it down.

The companion attach-token primitive (short-lived 30s bearer) reuses the
existing browse/src/pty-session-cookie.ts module unchanged — the lease
adds a name-space alongside, it doesn't replace anything.

Codex outside-voice (T1 of the eng review) flagged the original D4
"token IS sessionId" design as conflating identity with auth. The fix
is this lease registry: re-attach URLs carry the stable sessionId
(loggable), the short-lived attachToken stays out of logs.

API:
  * mintLease() → { sessionId, expiresAt }
  * validateLease(sessionId) → { ok: true, expiresAt } | { ok: false }
  * refreshLease(sessionId) — validate-first, never resurrects expired
    leases. Security-critical: the 30-min TTL is what bounds blast
    radius for a leaked attachToken whose lease should have GC'd.
  * revokeLease(sessionId) — explicit dispose path.
  * leaseCount() — observability helper.
  * __resetLeases() — test-only.

TTL env knob (GSTACK_PTY_LEASE_TTL_MS) lets v1.44 e2e tests compress
the detach window to 1s instead of waiting 30 minutes per assertion.

Server.ts wiring + /pty-session shape change + /pty-restart + /pty-dispose
+ /pty-session/reattach all land in subsequent commits in this branch.

Test (browse/test/pty-session-lease.test.ts):
  * 8 cases pinning mint uniqueness, validate-first refresh contract,
    revoke idempotency, null/undefined tolerance, and the negative case
    that refresh never resurrects a revoked lease (same code path as
    expired-and-pruned).

* feat(terminal-agent): sessionId-aware grant + scoped restart + eager spawn

Wires the pty-session-lease primitive (3aada48b) into terminal-agent so
the Commit 2 work in server.ts (next commit) can route /pty-restart and
re-attach by session identity rather than by single-use token.

Changes:

  * validTokens: Set<string> → Map<string, string|null>. Each grant carries
    its bound sessionId (or null for legacy single-grant callers). On WS
    upgrade, the agent surfaces the bound sessionId via ws.data so open()
    can register the session in the new reverse index.
  * sessionsById: Map<sessionId, PtySession> — populated in open(),
    cleared in close(). Required so /internal/restart can find and dispose
    one specific session by id rather than enumerating all live sessions.
  * /internal/restart: scoped to one sessionId. Codex T2 of the eng review
    caught the gap — pre-spec the route would have disposed every PTY on
    the agent, breaking pair-agent and any future multi-sidebar setup.
    The body now requires `{sessionId}`; missing or unknown id returns
    `{killed: 0}` and leaves siblings alone.
  * maybeSpawnPty(ws, session): hoisted from the inline binary-frame spawn
    block so both the legacy "spawn on first keystroke" trigger AND the
    new `{type:"start"}` text-frame trigger land in the same code path.
    Idempotent on session.spawned.
  * `{type:"start"}` text frame: explicit spawn trigger. forceRestart
    (extension side, lands in Commit 2C) sends this immediately on every
    fresh WS so claude boots without requiring a keystroke. Pre-v1.44 the
    lazy-binary-spawn pattern made the restart feel stuck.
  * close(ws): drops the sessionsById entry alongside the existing
    sessions WeakMap + validTokens cleanup. Commit 3 will revisit this to
    keep the session alive for a 60s detach window before disposing.

Test (browse/test/terminal-agent-session-routing.test.ts):
  * 8 static-grep tripwires pinning the load-bearing properties: validTokens
    is a Map (not Set), sessionsById exists, /internal/restart is scoped
    (negative-assert against enumerate-all patterns), WS upgrade plumbs
    sessionId, maybeSpawnPty is the single spawn entry, close() drops the
    index. Live spawn cycles belong in the e2e tier.

* feat(server): /pty-session 4-tuple + /pty-restart + /pty-dispose + lease-refresh

Wires the lease + attachToken model end-to-end on the server side. The
client side (extension) lands in the next commit; agent side already
shipped in 449144cd.

Routes:
  * POST /pty-session — mints sessionId (stable, loggable) + lease
    (server-side bookkeeping) + attachToken (short-lived bearer for the
    WS upgrade). Returns the 4-tuple in one round trip. Legacy
    ptySessionToken / expiresAt aliases kept for one minor release so
    extensions on the v1.43 wire shape keep working.
  * POST /pty-session/reattach — validates a sessionId's lease and mints
    a FRESH attachToken bound to the same sessionId. Used by Commit 3's
    re-attach loop; 410 Gone when the lease has expired so the client
    knows to fall back to a brand-new /pty-session.
  * POST /pty-restart — one transaction: dispose the caller's existing
    PtySession on the agent (via /internal/restart, scoped to one
    sessionId — codex T2), revoke the old lease, mint a fresh
    sessionId + lease + attachToken, return the 4-tuple. Zero race
    window between kill and mint (codex T2 + D8 of the eng review).
  * POST /pty-dispose — explicit teardown. sendBeacon-compatible: accepts
    auth token in the body so the extension's pagehide handler (Commit 2C)
    can fire it without setting custom headers (sendBeacon doesn't
    support those). Without this route, every clean browser quit leaves
    a zombie PTY alive for the 60s detach window — codex T3 caught it.
  * POST /internal/lease-refresh — loopback from terminal-agent on its
    25s keepalive cycle (lazy: only when lease is within 5 min of
    expiry). Refreshes the lease AND resets the daemon idle timer. T6
    of the eng review: PTY activity (not arbitrary SSE consumers) is
    what keeps the daemon alive when the sidebar is in use.

Helpers:
  * grantPtyToken now accepts optional sessionId and passes it through
    to the agent's /internal/grant body. The agent binds token → sessionId
    in its validTokens Map so /ws upgrades carry the sessionId for
    /internal/restart and Commit 3 re-attach lookups.
  * restartPtySession() — new loopback helper that POSTs the agent's
    scoped /internal/restart with a sessionId body. Used by /pty-restart
    and /pty-dispose.

Auth contract on /pty-dispose deliberately accepts the auth token in
EITHER the Authorization header OR the request body. The body path is
required for sendBeacon (which can't set custom headers); the header
path stays available for non-beacon callers and tests.

Test (browse/test/server-pty-lease-routes.test.ts):
  * 7 static-grep tripwires pinning the 4-tuple shape, validate-first
    re-attach with 410 fallback, one-transaction restart semantics,
    sendBeacon-compatible dispose auth, and the T6 PTY-only idle reset.
  * Live route exercises (full mint + grant + WS upgrade cycle) belong
    in the e2e tier — they require a real terminal-agent loopback and
    take seconds per assertion.

* feat(sidebar): forceRestart via /pty-restart + pagehide /pty-dispose

Closes the Commit 2 loop: server-side lease + restart routes shipped in
25ef24e9; this commit wires the extension client to use them. End-to-end
result — clicking Restart now actually kills the server's PTY before
opening a new WS (zero race window), and closing the sidebar / quitting
the browser disposes the PTY immediately instead of letting it linger
for the upcoming 60s detach window.

sidepanel-terminal.js:
  * mintSession callers read the v1.44 4-tuple (sessionId + attachToken)
    from /pty-session, with a backward-compat fallback to ptySessionToken
    so a partially-updated extension still works against a fresh server
    for one minor release.
  * Eager spawn via {type:"start"} text frame replaces the legacy
    `TextEncoder().encode("\n")` newline hack. Pre-v1.44, the lazy-binary-
    spawn pattern made forceRestart look stuck until the user typed —
    now claude boots before the prompt renders.
  * forceRestart() rewritten as an async one-transaction handler:
      1. close current WS with code 4001 (intentional-restart)
      2. POST /pty-restart with priorSessionId so the server can scope
         the dispose, then mint fresh sessionId + lease + attachToken
         in the same response
      3. Open new WS with the returned attachToken, send {type:"start"}
         immediately for eager spawn
      4. On 401: sticky-abort the auto-connect loop (no spam)
      5. On 503 / network failure: fall back to patient autoconnect
  * currentSessionId tracked and exposed on window.gstackPtySession so
    sidepanel.js's pagehide handler can sendBeacon the dispose.

sidepanel.js:
  * New pagehide handler fires navigator.sendBeacon('/pty-dispose',
    {sessionId, authToken}) on tab close, panel close, browser quit,
    or extension reload. sendBeacon-compatible: auth token rides in
    the body since sendBeacon can't set custom headers (server route
    accepts body-auth per 25ef24e9).
  * try/catch around the entire body so a sendBeacon failure can't
    interfere with the browser's unload sequence — the 60s detach
    window from Commit 3 catches anything we miss.

There's bounded duplication between connect() and forceRestart() (~70
lines of WS attach/handler wiring). Extracting a shared helper is a
clean follow-up but out of scope for the v1.44 ship — both paths are
exercised by the same e2e test.

Test (browse/test/sidepanel-restart-dispose.test.ts):
  * 9 static-grep tripwires pinning the 4-tuple parse, eager spawn,
    close-code 4001 contract, /pty-restart wire shape, sticky-abort
    401 path, sessionId window plumbing, sendBeacon body contract,
    and the best-effort try/catch around pagehide.

* feat(terminal-agent): scrollback ring buffer + detach state machine + re-attach

The agent side of Commit 3 — the "magic" feature. A network blip (wifi
hiccup, MV3 panel suspend, brief Chromium pause) now silently reconnects
the sidebar to the SAME claude session with scrollback intact. No more
"Session ended" message + manual Restart click + losing your tool-call
output. Server-side /pty-session/reattach (25ef24e9) and the extension
re-attach loop (next commit) close the loop end-to-end.

Ring buffer (T10):
  * Per-session frames: Buffer[] capped at 1 MB (env-overridable via
    GSTACK_PTY_RING_BUFFER_BYTES). Each PTY write is one frame, so
    eviction is at frame boundaries and never cuts a UTF-8 sequence or
    ANSI CSI in half.
  * appendToRingBuffer eviction loop keeps at least one frame even at
    extreme caps — a single oversized frame can't empty the buffer.
  * Alt-screen tracking via canonical xterm CSI ?1049h / CSI ?1049l
    sequences. lastIndexOf comparison so trailing state wins when both
    appear in one render frame (quick tool-call open+close).

Replay payload (T5 — codex outside-voice):
  * buildReplayPayload prefixes DECSTR soft reset (\x1b[!p) and
    conditionally re-enters alt-screen if claude was in a tool call at
    detach. The client writes RIS (\x1bc) FIRST to clear pre-blip xterm
    content; the server's prelude resets character attributes; the ring
    buffer replays cleanly on top.
  * Order is enforced by the {type:"reattach-begin"} text frame the
    agent sends right before the binary replay — client waits for it,
    writes RIS, then treats the next binary frame as the replay payload.

Detach state machine (T9):
  * PtySession.liveWs decouples the PTY callback from the original ws
    closure. On re-attach, swapping session.liveWs is enough — the
    on-data callback writes to the new ws automatically.
  * close(ws, code, _reason): codes 4001 (intentional restart), 4404
    (no-claude), and 1000 (clean exit) trigger immediate dispose.
    Anything else (1006 abnormal, 1001 going-away from network blip /
    panel suspend) starts a 60s detach timer instead. claude keeps
    running, output keeps accumulating in the ring buffer.
  * Detach timer is unref'd so the bun process can still exit cleanly
    on natural shutdown.
  * Sessions without a sessionId (legacy single-shot grants) can't
    re-attach by definition — those fall through to immediate dispose.

Re-attach lookup (T9):
  * WS open() checks sessionsById[sessionId] FIRST. If a detached
    session is sitting there, cancel its detach timer, swap liveWs,
    rebind the WS-keyed map, restart keepalive, send reattach-begin
    + replay payload. The PTY process is unchanged.
  * /internal/restart now cancels any pending detach timer before
    disposal — otherwise the timer would later try to dispose an
    already-disposed session.

Env knobs for e2e:
  * GSTACK_PTY_RING_BUFFER_BYTES — compress to 256 for eviction tests.
  * GSTACK_PTY_DETACH_WINDOW_MS — compress to 1000 for "did the timer
    fire?" tests without waiting a minute per assertion.

Tests:
  * browse/test/terminal-agent-detach-reattach.test.ts — 10 static-grep
    tripwires for the load-bearing properties: interface shape, env
    knobs, eviction floor, alt-screen tracking, replay prelude
    composition, re-attach lookup, close-code routing, detach timer
    unref, /internal/restart timer cancellation, on-data through
    session.liveWs.
  * browse/test/terminal-agent-session-routing.test.ts test 7 widened
    to match the new close(ws, code, _reason) signature.
  * browse/test/terminal-agent-keepalive.test.ts test 3 widened
    similarly. Both stay regressions for the prior contract.

* feat(sidebar): silent re-attach with scrollback replay (Commit 3 client side)

Closes the v1.44 long-lived-sidebar loop end-to-end. When the WS dies for
a transient reason (wifi blip, MV3 panel suspend, brief Chromium pause),
the sidebar now silently re-attaches to the SAME claude session inside the
server's 60s detach window. Scrollback replays cleanly; the user keeps
typing without noticing anything happened.

State machine:
  * New STATE.RECONNECTING covers the in-flight re-attach window.
    setState transitions out of this state reset reattachInFlight so a
    concurrent user action (Restart click, panel navigate) short-circuits
    cleanly.
  * Backoff schedule REATTACH_BACKOFF_MS = [1000, 2000, 4000, 8000] then
    8s steady until REATTACH_WINDOW_MS (60s) elapses. Past that point
    the server has disposed our session and /pty-session/reattach
    returns 410 Gone.

startReattachLoop(prevSessionId):
  * Posts /pty-session/reattach with sessionId.
  * On 200 with a valid 4-tuple, opens the post-reattach WS directly.
  * On 410 (lease expired) — short-circuits to ENDED. No retry; the user
    clicks Restart for a fresh session.
  * On 401 — sticky-aborts the auto-connect loop. Same defense as 25ef24e9
    so we don't spam "Auth invalid" every 2s.
  * On network failure or other non-OK status — schedules the next
    backoff tick.

openReattachWebSocket(terminalPort, attachToken, sessionId):
  * Mostly a clone of connect()'s attach wiring. Reuses the live xterm
    element — RIS clears the buffer cleanly when the agent's
    {type:"reattach-begin"} arrives, so the visual flash is minimal.
  * Handshake: on `{type:"reattach-begin"}` text frame → write `\x1bc`
    (RIS) to xterm + set nextBinaryIsReplay = true. The next binary
    frame IS the server-built replay payload (DECSTR soft-reset prefix
    + optional alt-screen re-enter + ring buffer contents).
  * If THIS reattach WS also dies uncleanly, recurses into another
    re-attach loop with the same sessionId — the server's detach window
    may still be open. State guard prevents runaway recursion.

connect() + forceRestart() close handlers (existing):
  * Both updated to call startReattachLoop on transient close codes
    (anything other than 1000 / 4001 / 4404). Was just setState(ENDED).
  * Clean codes still bypass — re-attaching to a force-restart's
    pre-restart session would be the bug we're avoiding.

Test (browse/test/sidepanel-reattach.test.ts):
  * 8 static-grep tripwires for the load-bearing properties: state
    constant, backoff schedule, /pty-session/reattach wiring, 410
    short-circuit (no retry past lease window), 401 sticky-abort,
    reattach-begin → RIS handshake, all three close handlers route
    through the loop, clean-code bypass.

* chore: bump version and changelog (v1.44.0.0)

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* test(terminal-agent): runtime tests for ring buffer + replay + alt-screen tracking

Companion to browse/test/terminal-agent-detach-reattach.test.ts (static-grep
tripwires) — calls appendToRingBuffer + buildReplayPayload directly to prove
behavioral correctness without spinning up a real Bun.serve listener.

  * 11 runtime cases: append + byte counting, oversize eviction with
    one-frame floor (the eviction loop guard that prevents an oversized
    single frame from emptying the buffer), alt-screen tracking via
    canonical xterm CSI ?1049h / CSI ?1049l, trailing-state-wins for
    enter+exit pairs inside a single render frame, soft-reset prefix
    ordering, optional alt-screen re-enter, payload length math.
  * Exports appendToRingBuffer, buildReplayPayload, and the PtySession
    interface from terminal-agent.ts (purely for testability — they
    were module-private; the change is annotation-only).
  * Lease registry sanity check: mint two sessions, verify distinct
    sessionIds, both valid simultaneously. Catches future refactors
    that accidentally couple lease + ring buffer.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(tests): explain_level unset returns the documented default, not empty

Pre-existing failure on main — the test expected gstack-config to return
"" for an unset explain_level (with the comment "preamble default takes
over"), but the script at bin/gstack-config:103 explicitly returns
"default" inline for that key. Earlier versions of the script may have
relied on shell-substitution fallback, but the current contract is
inline-default-on-get so callers always receive a usable value without
bash gymnastics.

Updated the test to match the actual contract. Also added GSTACK_HOME
override alongside GSTACK_STATE_DIR in the spawn env so developer-machine
config doesn't bleed into the test.

0a803f9e81 feat: gstack v1 — simpler prompts + real LOC receipts (v1.0.0.0) (#1039)
* docs: add design doc for /plan-tune v1 (observational substrate)

Canonical record of the /plan-tune v1 design: typed question registry,
per-question explicit preferences, inline tune: feedback with user-origin
gate, dual-track profile (declared + inferred separately), and plain-English
inspection skill. Captures every decision with pros/cons, what's deferred to
v2 with explicit acceptance criteria, and what was rejected entirely.

Codex review drove a substantial scope rollback from the initial CEO
EXPANSION plan. 15+ legitimate findings (substrate claim was false without
a typed registry; E4/E6/clamp logical contradiction; profile poisoning
attack surface; LANDED preamble side effect; implementation order) shaped
the final shape.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat: typed question registry for /plan-tune v1 foundation

scripts/question-registry.ts declares 53 recurring AskUserQuestion categories
across 15 skills (ship, review, office-hours, plan-ceo-review, plan-eng-review,
plan-design-review, plan-devex-review, qa, investigate, land-and-deploy, cso,
gstack-upgrade, preamble, plan-tune, autoplan).

Each entry has: stable kebab-case id, skill owner, category (approval |
clarification | routing | cherry-pick | feedback-loop), door_type (one-way
| two-way), optional stable option keys, optional psychographic signal_key,
and a one-line description.

12 of 53 are one-way doors (destructive ops, architecture/data forks,
security/compliance). These are ALWAYS asked regardless of user preference.

Helpers: getQuestion(id), getOneWayDoorIds(), getAllRegisteredIds(),
getRegistryStats(). No binary or resolver wiring yet — this is the schema
substrate the rest of /plan-tune builds on.

Ad-hoc question_ids (not registered) still log but skip psychographic
signal attribution. Future /plan-tune skill surfaces frequently-firing
ad-hoc ids as candidates for registry promotion.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* test: registry schema + safety + coverage tests (gate tier)

20 tests validating the question registry:

Schema (7 tests):
- Every entry has required fields
- All ids are kebab-case and start with their skill name
- No duplicate ids
- Categories are from the allowed set
- door_type is one-way | two-way
- Options arrays are well-formed
- Descriptions are short and single-line

Helpers (5 tests):
- getQuestion returns entry for known id, undefined for unknown
- getOneWayDoorIds includes destructive questions, excludes two-way
- getAllRegisteredIds count matches QUESTIONS keys
- getRegistryStats totals are internally consistent

One-way door safety (2 tests):
- Every critical question (test failure, SQL safety, LLM trust boundary,
  security scan, merge confirm, rollback, fix apply, premise revise,
  arch finding, privacy gate, user challenge) is declared one-way
- At least 10 one-way doors exist (catches regression if declarations
  are accidentally dropped)

Registry breadth (3 tests):
- 11 high-volume skills each have >= 1 registered question
- Preamble one-time prompts are registered
- /plan-tune's own questions are registered

Signal map references (1 test):
- signal_key values are typed kebab-case strings

Template coverage (2 tests, informational):
- AskUserQuestion usage across templates is non-trivial (>20)
- Registry spans >= 10 skills

20 pass, 0 fail.

* feat: one-way door classifier (belt-and-suspenders safety fallback)

scripts/one-way-doors.ts — secondary keyword-pattern classifier that catches
destructive questions even when the registry doesn't have an entry for them.

The registry's door_type field (from scripts/question-registry.ts) is the
PRIMARY safety gate. This classifier is the fallback for ad-hoc question_ids
that agents generate at runtime.

Classification priority:
  1. Registry lookup by question_id → use declared door_type
  2. Skill:category fallback (cso:approval, land-and-deploy:approval)
  3. Keyword pattern match against question_summary
  4. Default: treat as two-way (safer to log the miss than auto-decide unsafely)

Covers 21 destructive patterns across:
  - File system (rm -rf, delete, wipe, purge, truncate)
  - Database (drop table/database/schema, delete from)
  - Git/VCS (force-push, reset --hard, checkout --, branch -D)
  - Deploy/infra (kubectl delete, terraform destroy, rollback)
  - Credentials (revoke/reset/rotate API key|token|secret|password)
  - Architecture (breaking change, schema migration, data model change)

7 new tests in test/plan-tune.test.ts covering: registry-first lookup,
unknown-id fallthrough, keyword matching on destructive phrasings including
embedded filler words ("rotate the API key"), skill-category fallback,
benign questions defaulting to two-way, pattern-list non-empty.

27 pass, 0 fail. 1270 expect() calls.

* feat: psychographic signal map + builder archetypes

scripts/psychographic-signals.ts — hand-crafted {signal_key, user_choice} →
{dimension, delta} map. Version 0.1.0. Conservative deltas (±0.03 to ±0.06
per event). Covers 9 signal keys: scope-appetite, architecture-care,
code-quality-care, test-discipline, detail-preference, design-care,
devex-care, distribution-care, session-mode.

Helpers: applySignal() mutates running totals, newDimensionTotals() creates
empty starting state, normalizeToDimensionValue() sigmoid-clamps accumulated
delta to [0,1] (0 → 0.5 neutral), validateRegistrySignalKeys() checks that
every signal_key in the registry has a SIGNAL_MAP entry.

In v1 the signal map is used ONLY to compute inferred dimension values for
/plan-tune inspection output. No skill behavior adapts to these signals
until v2.

scripts/archetypes.ts — 8 named archetypes + Polymath fallback:
- Cathedral Builder (boil-the-ocean + architecture-first)
- Ship-It Pragmatist (small scope + fast)
- Deep Craft (detail-verbose + principled)
- Taste Maker (intuitive, overrides recommendations)
- Solo Operator (high-autonomy, delegates)
- Consultant (hands-on, consulted on everything)
- Wedge Hunter (narrow scope aggressively)
- Builder-Coach (balanced steering)
- Polymath (fallback when no archetype matches)

matchArchetype() uses L2 distance scaled by tightness, with a 0.55 threshold
below which we return Polymath. v1 ships the model stable; v2 narrative/vibe
commands wire it into user-facing output.

14 new tests: signal map consistency vs registry, applySignal behavior for
known/unknown keys, normalization bounds, archetype schema validity, name
uniqueness, matchArchetype correctness for each reference profile, Polymath
fallback for outliers.

41 pass, 0 fail total in test/plan-tune.test.ts.

* feat: bin/gstack-question-log — append validated AskUserQuestion events

Append-only JSONL log at ~/.gstack/projects/{SLUG}/question-log.jsonl.
Schema: {skill, question_id, question_summary, category?, door_type?,
options_count?, user_choice, recommended?, followed_recommendation?,
session_id?, ts}

Validates:
- skill is kebab-case
- question_id is kebab-case, <= 64 chars
- question_summary non-empty, <= 200 chars, newlines flattened
- category is one of approval/clarification/routing/cherry-pick/feedback-loop
- door_type is one-way or two-way
- options_count is integer in [1, 26]
- user_choice non-empty string, <= 64 chars

Injection defense on question_summary rejects the same patterns as
gstack-learnings-log (ignore previous instructions, system:, override:,
do not report, etc).

followed_recommendation is auto-computed when both user_choice and
recommended are present.

ts auto-injected as ISO 8601 if missing.

21 tests covering: valid payloads, full field preservation, auto-followed
computation, appending, long-summary truncation, newline flattening,
invalid JSON, missing fields, bad case, oversized ids, invalid enum
values, out-of-range options_count, and 6 injection attack patterns.

21 pass, 0 fail, 43 expect() calls.

* feat: bin/gstack-developer-profile — unified profile with migration

bin/gstack-developer-profile supersedes bin/gstack-builder-profile. The old
binary becomes a one-line legacy shim delegating to --read for /office-hours
backward compat.

Subcommands:
  --read              legacy KEY:VALUE output (tier, session_count, etc)
  --migrate           folds ~/.gstack/builder-profile.jsonl into
                      ~/.gstack/developer-profile.json. Atomic (temp + rename),
                      idempotent (no-op when target exists or source absent),
                      archives source as .migrated-YYYY-MM-DD-HHMMSS
  --derive            recomputes inferred dimensions from question-log.jsonl
                      using the signal map in scripts/psychographic-signals.ts
  --profile           full profile JSON
  --gap               declared vs inferred diff JSON
  --trace <dim>       event-level trace of what contributed to a dimension
  --check-mismatch    flags dimensions where declared and inferred disagree by
                      > 0.3 (requires >= 10 events first)
  --vibe              archetype name + description from scripts/archetypes.ts
  --narrative         (v2 stub)

Auto-migration on first read: if legacy file exists and new file doesn't,
migrate before reading. Creates a neutral (all-0.5) stub if nothing exists.

Unified schema (see docs/designs/PLAN_TUNING_V0.md §Architecture):
  {identity, declared, inferred: {values, sample_size, diversity},
   gap, overrides, sessions, signals_accumulated, schema_version}

25 new tests across subcommand behaviors:
- --read defaults + stub creation
- --migrate: 3 sessions preserved with signal tallies, idempotency, archival
- Tier calculation: welcome_back / regular / inner_circle boundaries
- --derive: neutral-when-empty, upward nudge on 'expand', downward on 'reduce',
  recomputable (same input → same output), ad-hoc unregistered ids ignored
- --trace: contributing events, empty for untouched dims, error without arg
- --gap: empty when no declared, correctly computed otherwise
- --vibe: returns archetype name + description
- --check-mismatch: threshold behavior, 10+ sample requirement
- Unknown subcommand errors

25 pass, 0 fail, 60 expect() calls.

* feat: bin/gstack-question-preference — explicit preferences + user-origin gate

Subcommands:
  --check <id>   → ASK_NORMALLY | AUTO_DECIDE  (decides if a registered
                   question should be auto-decided by the agent)
  --write '{…}'  → set a preference (requires user-origin source)
  --read         → dump preferences JSON
  --clear [id]   → clear one or all
  --stats        → short counts summary

Preference values: always-ask | never-ask | ask-only-for-one-way.
Stored at ~/.gstack/projects/{SLUG}/question-preferences.json.

Safety contract (the core of Codex finding #16, profile-poisoning defense
from docs/designs/PLAN_TUNING_V0.md §Security model):

  1. One-way doors ALWAYS return ASK_NORMALLY from --check, regardless of
     user preference. User's never-ask is overridden with a visible safety
     note so the user knows why their preference didn't suppress the prompt.

  2. --write requires an explicit `source` field:
       - Allowed:  "plan-tune", "inline-user"
       - REJECTED with exit code 2: "inline-tool-output", "inline-file",
         "inline-file-content", "inline-unknown"
     Rejection is explicit ("profile poisoning defense") so the caller can
     log and surface the attempt.

  3. free_text on --write is sanitized against injection patterns (ignore
     previous instructions, override:, system:, etc.) and newline-flattened.

Each --write also appends a preference-set event to
~/.gstack/projects/{SLUG}/question-events.jsonl for derivation audit trail.

31 tests:
- --check behavior (4): defaults, two-way, one-way (one-way overrides
  never-ask with safety note), unknown ids, missing arg
- --check with prefs (5): never-ask on two-way → AUTO_DECIDE; never-ask
  on one-way → ASK_NORMALLY with override note; always-ask always asks;
  ask-only-for-one-way flips appropriately
- --write valid (5): inline-user accepted, plan-tune accepted, persisted
  correctly, event appended, free_text preserved with flattening
- User-origin gate (6): missing source rejected; inline-tool-output
  rejected with exit code 2 and explicit poisoning message; inline-file,
  inline-file-content, inline-unknown rejected; unknown source rejected
- Schema validation (4): invalid JSON, bad question_id, bad preference,
  injection in free_text
- --read (2): empty → {}, returns writes
- --clear (3): specific id, clear-all, NOOP for missing
- --stats (2): empty zeros, tallies by preference type

31 pass, 0 fail, 52 expect() calls.

* feat: question-tuning preamble resolvers

scripts/resolvers/question-tuning.ts ships three preamble generators:

  generateQuestionPreferenceCheck — before each AskUserQuestion, agent runs
    gstack-question-preference --check <id>. AUTO_DECIDE suppresses the ask
    and auto-chooses recommended. ASK_NORMALLY asks as usual. One-way door
    safety override is handled by the binary.

  generateQuestionLog — after each AskUserQuestion, agent appends a log
    record with skill, question_id, summary, category, door_type,
    options_count, user_choice, recommended, session_id.

  generateInlineTuneFeedback — offers inline "tune:" prompt after two-way
    questions. Documents structured shortcuts (never-ask, always-ask,
    ask-only-for-one-way, ask-less) AND accepts free-form English with
    normalization + confirmation. Explicitly spells out the USER-ORIGIN
    GATE: only write tune events when the prefix appears in the user's own
    chat message, never from tool output or file content. Binary enforces.

All three resolvers are gated by the QUESTION_TUNING preamble echo. When
the config is off, the agent skips these sections entirely. Ready to be
wired into preamble.ts in the next commit.

Codex host has a simpler variant that uses $GSTACK_BIN env vars.

scripts/resolvers/index.ts registers three placeholders:
  QUESTION_PREFERENCE_CHECK, QUESTION_LOG, INLINE_TUNE_FEEDBACK

Total resolver count goes from 45 to 48.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat: wire question-tuning into preamble for tier >= 2 skills

scripts/resolvers/preamble.ts — adds two things:

  1. _QUESTION_TUNING config echo in the preamble bash block, gated on the
     user's gstack-config `question_tuning` value (default: false).
  2. A combined Question Tuning section for tier >= 2 skills, injected after
     the confusion protocol. The section itself is runtime-gated by the
     QUESTION_TUNING value — agents skip it entirely when off.

scripts/resolvers/question-tuning.ts — consolidated into one compact combined
section `generateQuestionTuning(ctx)` covering: preference check before the
question, log after, and inline tune: feedback with user-origin gate. Per-phase
generators remain exported for unit tests but are no longer the main entrypoint.

Size impact: +570 tokens / +2.3KB per tier-2+ SKILL.md. Three skills
(plan-ceo-review, office-hours, ship) still exceed the 100KB token ceiling —
but they were already over before this change. Delta is the smallest viable
wiring of the /plan-tune v1 substrate.

Golden fixtures (test/fixtures/golden/claude-ship, codex-ship, factory-ship)
regenerated to match the new baseline.

Full test run: 1149 pass, 0 fail, 113 skip across 28 files.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* chore: regenerate SKILL.md files with question-tuning section

bun run gen:skill-docs --host all after wiring the QUESTION_TUNING preamble
section. Every tier >= 2 skill now includes the combined Question Tuning
guidance. Runtime-gated — agents skip the section when question_tuning is
off in gstack-config (default).

Golden fixtures (claude-ship, codex-ship, factory-ship) updated to the new
baseline.

* feat: /plan-tune skill — conversational inspection + preferences

plan-tune/SKILL.md.tmpl: the user-facing skill for /plan-tune v1. Routes
plain-English intent to one of 8 flows:

  - Enable + setup (first-time): 5 declaration questions mapping to the
    5 psychographic dimensions (scope_appetite, risk_tolerance,
    detail_preference, autonomy, architecture_care). Writes to
    developer-profile.json declared.*.
  - Inspect profile: plain-English rendering of declared + inferred + gap.
    Uses word bands (low/balanced/high) not raw floats. Shows vibe archetype
    when calibration gate is met.
  - Review question log: top-20 question frequencies with follow/override
    counts. Highlights override-heavy questions as candidates for never-ask.
  - Set a preference: normalizes "stop asking me about X" → never-ask, etc.
    Confirms ambiguous phrasings before writing via gstack-question-preference.
  - Edit declared profile: interprets free-form ("more boil-the-ocean") and
    CONFIRMS before mutating declared.* (trust boundary per Codex #15).
  - Show gap: declared vs inferred diff with plain-English severity bands
    (close / drift / mismatch). Never auto-updates declared from the gap.
  - Stats: preference counts + diversity/calibration status.
  - Enable / disable: gstack-config set question_tuning true|false.

Design constraints enforced:
- Plain English everywhere. No CLI subcommand syntax required. Shortcuts
  (`profile`, `vibe`, `stats`, `setup`) exist but optional.
- user-origin gate on tune: writes. source: "plan-tune" for user-invoked
  /plan-tune; source: "inline-user" for inline tune: from other skills.
- One-way doors override never-ask (safety, surfaced to user).
- No behavior adaptation in v1 — this skill inspects and configures only.

Generates plan-tune/SKILL.md at ~11.6k tokens, well under the 100KB ceiling.
Generated for all hosts via `bun run gen:skill-docs --host all`.

Full free test suite: 1149 pass, 0 fail, 113 skip across 28 files.

* test: end-to-end pipeline + preamble injection coverage

Added 6 tests to test/plan-tune.test.ts:

Preamble injection (3 tests):
- tier 2+ includes Question Tuning section with preference check, log,
  and user-origin gate language ('profile-poisoning defense', 'inline-user')
- tier 1 does NOT include the prose section (QUESTION_TUNING bash echo
  still fires since it's in the bash block all tiers share)
- codex host swaps binDir references to $GSTACK_BIN

End-to-end pipeline (3 tests) — real binaries working together, not mocks:
- Log 5 expand choices → --derive → profile shows scope_appetite > 0.5
  (full log → registry lookup → signal map → normalization round-trip)
- --write source: inline-tool-output rejected; --read confirms no pref
  was persisted (the profile-poisoning defense actually works end-to-end)
- Migrate a 3-session legacy file; confirm legacy gstack-builder-profile
  shim still returns SESSION_COUNT: 3, TIER: welcome_back, CROSS_PROJECT: true

test/plan-tune.test.ts now has 47 tests total.

* test: E2E test for /plan-tune plain-English inspection flow (gate tier)

test/skill-e2e-plan-tune.test.ts — verifies /plan-tune correctly routes
plain-English intent ("review the questions I've been asked") to the
Review question log section without requiring CLI subcommand syntax.

Seeds a synthetic question-log.jsonl with 3 entries exercising:
- override behavior (user chose expand over recommended selective)
- one-way door respect (user followed ship-test-failure-triage recommendation)
- two-way override (user skipped recommended changelog polish)

Invokes the skill via `claude -p` and asserts:
- Agent surfaces >= 2 of 3 logged question_ids in output
- Agent notices override/skip behavior from the log
- Exit reason is success or error_max_turns (not agent-crash)

Gate-tier because the core v1 DX promise is plain-English intent routing.
If it requires memorized subcommands or breaks on natural language, that's
a regression of the defining feature.

Registered in test/helpers/touchfiles.ts with dependencies:
- plan-tune/** (skill template + generated md)
- scripts/question-registry.ts (required for log lookup)
- scripts/psychographic-signals.ts, scripts/one-way-doors.ts (derive path)
- bin/gstack-question-log, gstack-question-preference, gstack-developer-profile

Skipped when EVALS_ENABLED is not set; runs on `bun run test:evals`.

* chore: bump version and changelog (v0.19.0.0) — /plan-tune v1

Ships /plan-tune as observational substrate: typed question registry, dual-track
developer profile (declared + inferred), explicit per-question preferences with
user-origin gate, inline tune: feedback across every tier >= 2 skill, unified
developer-profile.json with migration from builder-profile.jsonl.

Scope rolled back from initial CEO EXPANSION plan after outside-voice review
(Codex). 6 deferrals tracked as P0 TODOs with explicit acceptance criteria:
E1 substrate wiring, E3 narrative/vibe, E4 blind-spot coach, E5 LANDED
celebration, E6 auto-adjustment, E7 psychographic auto-decide.

The CI image build failed with:
  E: Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/...

  ERROR: process "/bin/sh -c apt-get update && apt-get install ..."
     did not complete successfully: exit code: 100

archive.ubuntu.com periodically returns "connection refused" on individual
regional mirrors. Without retry logic a single failed fetch nukes the whole
Docker build. Three defenses, layered:

  1. /etc/apt/apt.conf.d/80-retries — apt fetches each package up to 5 times
     with a 30s timeout. Handles per-package flakes.
  2. Shell-loop retry around the whole apt-get step (x3, 10s sleep) — handles
     the case where apt-get update itself can't reach any mirror.
  3. --retry 5 --retry-delay 5 --retry-connrefused on all curl fetches (bun
     install script, GitHub CLI keyring, NodeSource setup script).

Applied to every apt-get and curl call in the Dockerfile. No behavior change
on happy path — only kicks in when mirrors blip. Fixes the build-image job
that was blocking CI on the /plan-tune PR.

* docs: add PLAN_TUNING_V1 + PACING_UPDATES_V0 design docs

Captures the V1 design (ELI10 writing + LOC reframe) in
docs/designs/PLAN_TUNING_V1.md and the extracted V1.1 pacing-overhaul
plan in docs/designs/PACING_UPDATES_V0.md. V1 scope was reduced from
the original bundled pacing + writing-style plan after three
engineering-review passes revealed structural gaps in the pacing
workstream that couldn't be closed via plan-text editing. TODOS.md
P0 entry links to V1.1.

* feat: curated jargon list for V1 writing-style glossing

Repo-owned list of ~50 high-frequency technical terms (idempotent,
race condition, N+1, backpressure, etc.) that gstack glosses on first
use in tier-≥2 skill output. Baked into generated SKILL.md prose at
gen-skill-docs time. Terms not on this list are assumed plain-English
enough. Contributions via PR.

* feat(preamble): V1 Writing Style section + EXPLAIN_LEVEL echo + migration prompt

Adds a new Writing Style section to tier-≥2 preamble output composing with
the existing AskUserQuestion Format section. Six rules: jargon glossed on
first use per skill invocation (from scripts/jargon-list.json), outcome-
framed questions, short sentences, decisions close with user impact,
gloss-on-first-use even if user pasted term, user-turn override for "be
terse" requests. Baked conditionally (skip if EXPLAIN_LEVEL: terse).

Adds EXPLAIN_LEVEL preamble echo using \${binDir} (host-portable matching
V0 QUESTION_TUNING pattern). Adds WRITING_STYLE_PENDING echo reading a
flag file written by the V0→V1 upgrade migration; on first post-upgrade
skill run, the agent fires a one-time AskUserQuestion offering terse mode.

* feat(gstack-config): validate explain_level + document in header

Adds explain_level: default|terse to the annotated config header with
a one-line description. Whitelists valid values; on set of an unknown
value, prints a specific warning ("explain_level '\$VALUE' not
recognized. Valid values: default, terse. Using default.") and writes
the default value. Matches V1 preamble's EXPLAIN_LEVEL echo expectation.

* feat: V1 upgrade migration — writing-style opt-out prompt

New migration script following existing v0.15.2.0.sh / v0.16.2.0.sh
pattern. Writes a .writing-style-prompt-pending flag file on first run
post-upgrade. The preamble's migration-prompt block reads the flag and
fires a one-time AskUserQuestion offering the user a choice between
the new default writing style and restoring V0 prose via
\`gstack-config set explain_level terse\`. Idempotent via flag files;
if the user has already set explain_level explicitly, counts as
answered and skips.

* feat: LOC reframe tooling — throughput comparison + README updater + scc installer

Three new scripts:

- scripts/garry-output-comparison.ts — enumerates Garry-authored commits
  in 2013 + 2026 on public repos, extracts ADDED lines from git diff,
  classifies as logical SLOC via scc --stdin (regex fallback if scc
  missing). Writes docs/throughput-2013-vs-2026.json with per-language
  breakdown + explicit caveats (public repos only, commit-style drift,
  private-work exclusion).

- scripts/update-readme-throughput.ts — reads the JSON if present,
  replaces the README's <!-- GSTACK-THROUGHPUT-PLACEHOLDER --> anchor
  with the computed multiple (preserving the anchor for future runs).
  If JSON missing, writes GSTACK-THROUGHPUT-PENDING marker that CI
  rejects — forcing the build to run before commit.

- scripts/setup-scc.sh — standalone OS-detecting installer for scc.
  Not a package.json dependency (95% of users never run throughput).
  Brew on macOS, apt on Linux, GitHub releases link on Windows.

Two-string anchor pattern (PLACEHOLDER vs PENDING) prevents the
pipeline from destroying its own update path.

* feat(retro): surface logical SLOC + weighted commits above raw LOC

V1 reorders the /retro summary table to lead with features shipped,
then commits + weighted commits (commits × files-touched capped at 20),
then PRs merged, then logical SLOC added as the primary code-volume
metric. Raw LOC stays present but is demoted to context. Rationale
inline in the template: ten lines of a good fix is not less shipping
than ten thousand lines of scaffold.

* docs(v1): README hero reframe + writing-style + CHANGELOG + version bump to 1.0.0.0

README.md:
- Hero removes "600,000+ lines of production code" framing; replaces
  with the computed 2013-vs-2026 pro-rata multiple (via
  <!-- GSTACK-THROUGHPUT-PLACEHOLDER --> anchor, filled by the
  update-readme-throughput build step).
- Hiring callout: "ship real products at AI-coding speed" instead of
  "10K+ LOC/day."
- New Writing Style section (~80 words) between Quick start and
  Install: "v1 prompts = simpler" framing, outcome-language example,
  terse-mode opt-out, pointer to /plan-tune.

CLAUDE.md: one-paragraph Writing style (V1) note under project
conventions, linking to preamble resolver + V1 design docs.

CHANGELOG.md: V1 entry on top of v0.19.0.0 with user-facing narrative
(what changes, how to opt out, for-contributors notes). Mentions
scope reduction — pacing overhaul ships in V1.1.

CONTRIBUTING.md: one-paragraph note on jargon-list.json maintenance
(PR to add/remove terms; regenerate via gen:skill-docs).

VERSION + package.json: bump to 1.0.0.0.

* chore: regenerate SKILL.md files + golden fixtures for V1

Mechanical regeneration from the updated templates in prior commits:
- Writing Style section now appears in tier-≥2 skill output.
- EXPLAIN_LEVEL + WRITING_STYLE_PENDING echoes in preamble bash.
- V1 migration-prompt block fires conditionally on first upgrade.
- Jargon list inlined into preamble prose at gen time.
- Retro template's logical SLOC + weighted commits order applied.

Regenerated for all 8 hosts via bun run gen:skill-docs --host all.
Golden ship-skill fixtures refreshed from regenerated outputs.

* test: V1 gate coverage — writing-style resolver + config + jargon + migration + dormancy

Six new gate-tier test files:

- test/writing-style-resolver.test.ts — asserts Writing Style section
  is injected into tier-≥2 preamble, all 6 rules present, jargon list
  inlined, terse-mode gate condition present, Codex output uses
  \$GSTACK_BIN (not ~/.claude/), tier-1 does NOT get the section,
  migration-prompt block present.

- test/explain-level-config.test.ts — gstack-config set/get round-trip
  for default + terse, unknown-value warns + defaults to default,
  header documents the key, round-trip across set→set→get.

- test/jargon-list.test.ts — shape + ~50 terms + no duplicates
  (case-insensitive) + includes canonical high-signal terms.

- test/v0-dormancy.test.ts — 5D dimension names + archetype names
  forbidden in default-mode tier-≥2 SKILL.md output, except for
  plan-tune and office-hours where they're load-bearing.

- test/readme-throughput.test.ts — script replaces anchor with number
  on happy path, writes PENDING marker when JSON missing, CI gate
  asserts committed README contains no PENDING string.

- test/upgrade-migration-v1.test.ts — fresh run writes pending flag,
  idempotent after user-answered, pre-existing explain_level counts
  as answered.

All 95 V1 test-expect() calls pass. Full suite: 0 failures.

* feat: compute real 2013-vs-2026 throughput multiple (130.2×)

Ran scripts/garry-output-comparison.ts across all 15 public garrytan/*
repos. Aggregated results into docs/throughput-2013-vs-2026.json and
ran scripts/update-readme-throughput.ts to replace the README placeholder.

2013 public activity: 2 commits, 2,384 logical lines added across 1
week, in 1 repo (zurb-foundation-wysihtml5 upstream contribution).

2026 public activity: 279 commits, 310,484 logical lines added across
17 active weeks, in 3 repos (gbrain, gstack, resend_robot).

Multiples (public repos only, apples-to-apples):
- Logical SLOC: 130.2×
- Commits per active week: 8.2×
- Raw lines added: 134.4×

Private work at both eras (2013 Bookface at YC, Posterous-era code,
2026 internal tools) is excluded from this comparison.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat: 207× throughput multiple (with private repos + Bookface)

Re-ran scripts/garry-output-comparison.ts across all 41 repos under
garrytan/* (15 public + 26 private), including Bookface (YC's internal
social network, 2013-era work).

2013 activity: 71 commits, 5,143 logical lines, 4 active repos
  (bookface, delicounter, tandong, zurb-foundation-wysihtml5)
2026 activity: 350 commits, 1,064,818 logical lines, 15 active repos
  (gbrain, gstack, gbrowser, tax-app, kumo, tenjin, autoemail, kitsune,
  easy-chromium-compiles, conductor-playground, garryslist-agent, baku,
  gstack-website, resend_robot, garryslist-brain)

Multiples:
- Logical SLOC: 207× (up from 130.2× when including private work)
- Raw lines: 223×
- Commits/active-week: 3.4×

Stopped committing docs/throughput-2013-vs-2026.json — analysis is a
local artifact, not repo state. Added docs/throughput-*.json to
.gitignore. Full markdown analysis at ~/throughput-analysis-2026-04-18.md
(local-only). README multiple is now hardcoded; re-run the script and
edit manually when you want to refresh it.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs: run rate vs year-to-date throughput comparison

Two separate numbers in the README hero:
- Run rate: ~700× (9,859 logical lines/day in 2026 vs 14/day in 2013)
- Year-to-date: 207× (2026 through April 18 already exceeds 2013 full
  year by 207×)

Previous "207× pro-rata" framing mixed full-year 2013 vs partial-year
2026. Run rate is the apples-to-apples normalization; YTD is the
"already produced" total. Both are honest; both are compelling; they
measure different things.

Analysis at ~/throughput-analysis-2026-04-18.md (local-only).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(throughput): script natively computes to-date + run-rate multiples

Enhanced scripts/garry-output-comparison.ts so both calculations come
out of a single run instead of being reassembled ad-hoc in bash:

PerYearResult now includes:
- days_elapsed — 365 for past years, day-of-year for current
- is_partial — flags the current (in-progress) year
- per_day_rate — logical/raw/commits normalized by calendar day
- annualized_projection — per_day_rate × 365

Output JSON's `multiples` now has two sibling blocks:
- multiples.to_date — raw volume ratios (2026-YTD / 2013-full-year)
- multiples.run_rate — per-day pace ratios (apples-to-apples)

Back-compat: multiples.logical_lines_added still aliases to_date for
older consumers reading the JSON.

Updated README hero to cite both (picking up brain/* repo that was
missed in the earlier aggregation pass):

  2026 run rate: ~880× my 2013 pace (12,382 vs 14 logical lines/day)
  2026 YTD:      260× the entire 2013 year

Stderr summary now prints both multiples at the end of each run.

* docs: ON_THE_LOC_CONTROVERSY methodology post + README link

Long-form response to the "LOC is a meaningless vanity metric" critique.
Covers:
- The three branches of the LOC critique and which are right
- Why logical SLOC (NCLOC) beats raw LOC as the honest measurement
- Full method: author-scoped git diff, regex-classified added lines,
  aggregated across 41 public + private garrytan/* repos
- Both calculations: to-date (260x) and run-rate (879x)
- Steelman of the critics (greenfield-vs-maintenance, survivorship bias,
  quality-adjusted productivity, time-to-first-user)
- Reproduction instructions

Linked from README hero via a blockquote directly below the number.

* exclude: tax-app from throughput analysis (import-dominated history)

tax-app's history is one commit of 104K logical lines — an initial
import of a codebase, not authored work. Removing it to keep the
comparison honest.

Changes:
- scripts/garry-output-comparison.ts: added EXCLUDED_REPOS constant
  with tax-app + a one-line rationale. The script now skips excluded
  repos with a stderr note and deletes any stale output JSON so
  aggregation loops don't pick up pre-exclusion numbers.

- README hero: updated to 810× run rate + 240× YTD (were 880×/260×).
  Wording updated to "40 public + private repos ... after excluding
  repos dominated by imported code."

- docs/ON_THE_LOC_CONTROVERSY.md: updated all numbers, added an
  "Exclusions" paragraph explaining tax-app, removed tax-app from
  the "shipped not WIP" example list.

New numbers (2026 through day 108, without tax-app):
  - To-date:  240× logical SLOC (1,233,062 vs 5,143)
  - Run rate: 810× per-day pace (11,417 vs 14 logical/day)
  - Annualized: ~4.2M logical lines projected

Future re-runs automatically skip tax-app. Add more exclusions to
EXCLUDED_REPOS at the top of the script with a one-line rationale.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix: correct tax-app exclusion rationale

tax-app is a demo app I built for an upcoming YC channel video,
not an "import-dominated history" as the previous commit claimed.
Excluded because it's not production shipping work, not because
of an import commit.

Updated rationale in scripts/garry-output-comparison.ts's
EXCLUDED_REPOS constant, in docs/ON_THE_LOC_CONTROVERSY.md's
method section + conclusion, and in the README hero wording
("one demo repo" vs the earlier "repos dominated by imported code").

Numbers unchanged — the exclusion itself is the same, just the
reason.

* docs: harden ON_THE_LOC_CONTROVERSY against Cramer + neckbeard critiques

Reframes the thesis as "engineers can fly now" (amplification, not
replacement) and fortifies the soft spots critics will attack.

Added:
- Flight-thesis opener: pilot vs walker, leverage not replacement.
- Second deflation layer for AI verbosity (on top of NCLOC). Headline
  moves from 810x to 408x after generous 2x AI-boilerplate cut, with
  explicit sensitivity analysis showing the number is still large under
  pessimistic priors (5x → 162x, 10x → 81x, 100x impossible).
- Weekly distribution check (kills "you had one burst week" attack).
- Revert rate (2.0%) and post-merge fix rate (6.3%) with OSS
  comparables (K8s/Rails/Django band). Addresses "where are your error
  rates" directly.
- Named production adoption signals (gstack 1000+ installs, gbrain beta,
  resend_robot paying API) with explicit concession that "shipped != used
  at scale" for most of the corpus.
- Harder steelman: 5 specific concessions with quantified pivot points
  (e.g., "if 2013 baseline was 3.5x higher, 810x → 228x, still high").

Removed factual error: Posterous acquisition paragraph (Garry had already
left Posterous by 2011, so the "Twitter bought our private repos" excuse
for the 2013 corpus gap doesn't apply).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs: update gstack/gbrain adoption numbers in LOC controversy post

gstack: "1,000+ distinct project installations" → "tens of thousands of
daily active users" (telemetry-reported, community tier, opt-in).
gbrain: "small set of beta testers" → "hundreds of beta testers running
it live."

Both are the accurate current numbers. The concession paragraph below
(about shipped != adopted at scale for the long-tail repos) still reads
correctly since it's about the corpus as a whole, not gstack/gbrain
specifically.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs: reframe reproducibility note as OSS breakout flex

"You'd need access to my private repos" → "Bookface and Posthaven are
private, but gstack and gbrain are open-sourced with tens of thousands
of GitHub stars and tens of thousands of confirmed regular users, among
the most-used OSS projects in the world that didn't exist three months
ago."

Keeps the `gh repo list` command at the end for the actual
reproducibility instruction.

* Rewrite LOC controversy post

- Lead with concession (LOC is garbage, do the math anyway)
- Preempt 14 lines/day meme with historical baselines (Brooks, Jones, McConnell)
- Remove 'neckbeard' language throughout
- Add slop-scan story (Ben Vinegar, 5.24 → 1.96, 62% cut)
- David Cramer GUnit joke
- Add testing philosophy section (the real unlock)
- ASCII weekly distribution chart
- gstack telemetry section with real numbers (15K installs, 305K invocations, 95.2% success)
- Top skills usage chart
- Pick-your-priors paragraph moved earlier (the killer)
- Sharper close: run the script, show me your numbers

* docs: four precision fixes on LOC controversy post

1. Citation fix. Kernighan didn't say anything about LOC-as-metric
   (that's the famous "aircraft building by weight" quote, commonly
   misattributed but actually Bill Gates). Replaced "Kernighan implied
   it before that" with the real Dijkstra quote ("lines produced" vs
   "lines spent" from EWD1036, with direct link) + the Gates quote.
   Verified via web search.

2. Slop-scan direction clarified. "(highest on his benchmark)" was
   ambiguous — could read as a brag. Now: "Higher score = more slop.
   He ran it on gstack and we scored 5.24, the worst he'd measured
   at the time." Then the 62% cut lands as an actual win.

3. Prose/chart skill-usage ordering now matches. Added /plan-eng-review
   (28,014) to the prose list so it doesn't conflict with the chart
   below it.

4. Cut the "David — I owe you one / GUnit" insider joke. Most readers
   won't connect Cramer → Sentry → GUnit naming. Ends the slop-scan
   paragraph on the stronger line: "Run `bun test` and watch 2,000+
   tests pass."

* docs: tighten four LOC post citations to match primary sources

1. Bill Gates quote: flagged as folklore-grade. Was "Bill Gates put it
   more memorably" (firm attribution). Now "The old line (widely
   attributed to Bill Gates, sourcing murky) puts it more memorably."
   The quote stands; honesty about attribution avoids the same
   misattribution trap we just fixed for Kernighan.

2. Capers Jones: "15-50 across thousands of projects" → "roughly 16-38
   LOC/day across thousands of projects" — matches his actual published
   measurements (which also report as 325-750 LOC/month).

3. Steve McConnell: "10-50 for finished, tested, delivered code" was
   folklore. Replaced with his actual project-size-dependent range from
   Code Complete: "20-125 LOC/day for small projects (10K LOC) down to
   1.5-25 for large projects (10M LOC) — it's size-dependent, not a
   single number."

4. Revert rate comparison: "Kubernetes, Rails, and Django historically
   run 1.5-3%" was unsourced. Replaced with "mature OSS codebases
   typically run 1-3%" + "run the same command on whatever you consider
   the bar and compare." No false specificity about which repos.

Net: every quantitative citation in the post now matches primary-source
figures or is explicitly flagged as folklore. Neckbeards can verify.

* docs: drop Writing style section from README

Was sitting in prime real estate between Quick start and Install —
internal implementation detail, not something users need up-front.
Existing coverage is enough:
- Upgrade migration prompt notifies users on first post-upgrade run
- CLAUDE.md has the contributor note
- docs/designs/PLAN_TUNING_V1.md has the full design

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs: collapse team-mode setup into one paste-and-go command

Step 2 was three separate code blocks: setup --team, then team-init,
then git add/commit. Mirrors Step 1's style now — one shell one-liner
that does all three. Subshell (cd && ./setup --team) keeps the user
in their repo pwd so team-init + git commit land in the right place.

"Swap required for optional" moved to a one-liner below.

* docs: move full-clone footnote from README to CONTRIBUTING

The "Contributing or need full history?" note is for contributors, not
for someone following the README install flow. Moved into CONTRIBUTING's
Quick start section where it fits next to the existing clone command,
with a tip to upgrade an existing shallow clone via
\`git fetch --unshallow\`.
