v1.64.0.0 fix wave: full tracker audit — 90 fixes, 52 issues closed, ~50 community PRs absorbed (#2571)
* fix(hooks): nest freeze/careful permissionDecision under hookSpecificOutput

Claude Code ignores a top-level permissionDecision, so the /freeze deny and
/careful ask guards silently allowed everything. Nest both under
hookSpecificOutput with permissionDecisionReason, update the shape-blind
tests to pin the nested form, and document the constraint in both skill
templates (regen included).

Closes half of #1459 (freeze enforcement chain).

dedicated team-init fix).

* fix(team-init): required-mode hook blocks with nested schema + exit 2

The generated check-gstack.sh emitted a flat permissionDecision payload and
exited 0, which Claude Code ignores — required mode enforced nothing. The
generated hook now nests the deny under hookSpecificOutput and exits 2 so
the block holds even if the JSON schema drifts again. Adds a temp-repo
regression test that runs the generated hook under both installed and
missing-gstack homes.

Fixes #2413, #2296.

* fix(careful): close three check-careful bypasses via real JSON extraction

The grep-based command extractor stopped at the first escaped quote, so any
quoted argument truncated the command before the pattern checks ran —
`git commit -m "wip" && rm -rf /` was silently allowed. Replace it with a
python3/node JSON parse that fails CLOSED on unreadable payloads, add an
IFS/base64-to-shell obfuscation tripwire, and stop multi-line commands from
riding the single-line safe-exception whitelist (line-based grep would have
approved `rm -rf /` when a later line matched node_modules — a hazard the
real newline decoding exposed).

Contributed by @wtamminga (PR #2426; the -R hunk was dropped — it landed in
v1.61.0.0 — and output shapes updated to the nested hookSpecificOutput form).

* fix(review,autoplan): require explicit run_in_background: false on specialist agents

Claude Code v2.1.198 made subagents run in the background by default, which
inverted the old "do not use the flag" guidance: review-army specialists and
autoplan dual voices silently launched in the background and the merge step
could proceed before they completed — regressing the #497 fix. The generated
guidance now instructs an explicit run_in_background: false, and a static
tripwire fails the free suite if the inert inverted phrasing ever returns to
any generated SKILL.md.

Fixes #2440.

* fix(investigate): anchor the scope-lock freeze hook on $HOME, not CLAUDE_SKILL_DIR

The investigate skill's PreToolUse hooks and Scope Lock probe resolved
check-freeze.sh via ${CLAUDE_SKILL_DIR}, which does not exist when
frontmatter hooks run — the || exit 0 tail then failed open, so the debug
scope boundary silently never engaged (#1871 follow-up). Anchor all four
sites on $HOME/.claude/skills/gstack/ like careful/freeze, and add a static
test asserting no frontmatter command: line in the guard-family skills ever
references CLAUDE_SKILL_DIR again.

Fixes #2469; closes the last live half of #1459 together with the
freeze/careful hookSpecificOutput fix. The broader portable-install-root
rewrite stays #1882 (its own focused PR per the TODOS.md decision).

Reported with a fix by @maxpetrusenkoagent (PR #1873; absorbed narrowly —
the cwd-walk rewrite belongs to #1882).

* fix(redact): scan large diffs in line-aligned slices; stop digit-UUIDs matching as cards/phones

The prepush guard blocked any push whose added lines exceeded the engine's
1 MiB cap with engine.input_too_large — a size error naming no credential —
which trains people onto GSTACK_REDACT_PREPUSH=skip. Scan in 768 KiB
line-aligned slices instead (no pattern is multi-line, so a boundary cannot
bisect a secret); a single oversized line still goes to the engine intact and
fails closed. Also suppress card/phone matches whose span sits ENTIRELY
inside a UUID — digit-only UUID fixtures were 14 of 21 MEDIUM findings on an
ordinary branch, the noise level that stops people reading MEDIUM at all.

Fixes #2304.

* fix(redact-prepush): resolve the real push base instead of EMPTY_TREE whole-repo scans

When the remote default branch is not main/master (or origin/HEAD is unset),
the merge-base guess failed and the hook fell back to scanning the ENTIRE
repository as added lines — re-attributing long-pushed secrets to the
current push and, on any real repo, tripping the engine byte cap so the push
blocked having scanned nothing. Derive the base from commits reachable from
no remote-tracking branch, keep the empty-tree path only for genuinely fresh
repos, and split the block message so an unscannable diff is reported as
"could not scan (fail closed)" rather than "credential found — rotate it".

* fix(redact-prepush): preserve the trailing newline handed to chained pre-push.local

The chaining wrapper captured stdin with $(cat), which strips the trailing
newline — a chained shell hook built on `while read` then never entered its
loop for the final (usually only) ref line and exited 0, failing OPEN. Use
the printf-x sentinel so the byte-exact input reaches the chained hook, with
tests covering both the pass-through and the short-circuit paths.

* fix(redact-prepush): close the ext-diff, header-lookalike, and ref-parse bypasses

Three ways the pushed diff escaped scanning: (1) a user-level diff.external
or textconv driver replaced the diff with its own output — zero '+' lines,
so the scan saw nothing (now --no-ext-diff --no-textconv); (2) an added
content line whose text begins with "++" renders as "+++…" and the blanket
header skip dropped it (now hunk-aware header detection); (3) a pre-push
ref line that failed to parse was silently skipped, leaving that ref
unscanned (now fails closed with the offending line named).

Minimal reimplementation of the two confirmed bypasses from PR #2498 by
@lubosxyz (the full PR overlaps the chunked-scan work absorbed separately),
plus the unparseable-ref hardening.

* fix(pair-agent): keep the ngrok authtoken out of the transcript and shell argv

The not-authed flow told the user to paste their ngrok authtoken into the
chat so the agent could run `ngrok config add-authtoken` — putting a live
credential in the transcript, tool-call argv, and anything the transcript
syncs to. The user now runs the auth command in their own terminal; the
agent only verifies via `ngrok config check`, and a pasted token triggers a
rotate-and-reauth instruction. A static test pins that no agent-run bash
fence ever contains add-authtoken again.

Fixes #2335.

* fix(update-check): crash emits CHECK_FAILED instead of reading as up-to-date

gstack-update-check signals "up to date" with SILENCE, and it runs under
set -e — so any unguarded mid-script failure exited quietly and was
indistinguishable from a current install. Observed live as a 45-release
silent-staleness incident. An ERR trap (with -E so it propagates into
functions) now emits a CHECK_FAILED sentinel naming the line and status,
and exits 0 so caller `|| true` guards can't eat it. Behavioral tests cover
both the crash and the healthy-silent paths; egress-receipt wiring is
untouched and still pinned by test/egress-receipt-wiring.test.ts.

Fixes #1974. (#2378's HEAD-SHA staleness half was already fixed on main by
the ls-remote + SHA-pinned VERSION resolution — close as already-fixed.)

* fix(deps): bump diff 7.0.0 → 9.0.0 (GHSA-73rr-hh4g-fpgx parsePatch DoS)

The advisory affects diff 6.x–8.0.2. The only API this repo uses is
Diff.diffLines (browse/src/snapshot.ts:571, browse/src/meta-commands.ts:728),

* ci(evals): skip eval jobs deterministically on fork PRs

Fork PRs never receive repository secrets, so every API-calling eval failed
at SDK auth — but only when Docker-cache luck let the jobs start at all,
making fork PRs randomly red or grey. Skip the eval and report jobs
explicitly for fork-origin PRs, keep the image BUILD (validates
Dockerfile.ci changes) without the push a fork token can't perform, and
leave full coverage for same-repo PRs, pushes, and dispatches.

* fix(extension): deny token/port reads to content-script and foreign senders

background.js answered getPort — port, connected state, AND the browse
server auth token — to any sender that passed the type allowlist,
including content scripts running in web-page context and, behind only
the sender.id check, anything without extension-page provenance. The
getToken sender.tab restriction covered getToken alone, and only after
getPort had already handed out the token.

Single decision point now: extension/sender-auth.js classifies each
message type; the eight privileged types (getPort, setPort, getServerUrl,
getToken, fetchRefs, command, sidebar-command, getTabState) require an
own-extension-page sender (chrome-extension://<own id>/ URL, no
sender.tab, own sender.id). Denied senders get { error: 'unauthorized' }
and nothing else — never the token, never the port. Content-script flows
(elementPicked, pickerCancelled, inspectResult, openSidePanel) are
untouched, and the sidepanel/popup keep the getPort token field their
connect path reads. The policy mirrors the v1.63 server-side model:
AUTH_TOKEN is released only to the pinned extension Origin via
POST /extension-token, so the extension must not re-leak it to contexts
the server would never have trusted.

browse/test/extension-sender-auth.test.ts drives the real background.js
onMessage listener under a chrome stub with four sender shapes (own
extension page, own content script, foreign extension id, missing
sender.url) and pins that denied responses carry no token/port fields,
that a denied setPort never persists, that a denied command never
reaches the network, and that the inspector + tab-state flows keep
working. The helper is loaded via importScripts in the classic service
worker and require()-able from bun tests.

* test(update-check): fixture links gstack-egress-lib.sh — all 38 tests failed on main

v1.63.0.0 made bin/gstack-update-check source bin/gstack-egress-lib.sh
unconditionally, but the test fixture's GSTACK_DIR only linked gstack-config
— every test died at the source line (0/38 pass on pristine main,
verified). The suite-truncation bug hid it: the runner was killed by an
earlier file's delayed process.exit before this file ran. Link the lib like
the real install layout the script assumes.

* fix(browse): capture active-tab state before close() — last-tab auto-create raced the close event

closeTab checked `tabId === this.activeTabId` AFTER awaiting page.close(),
but the page 'close' event handler can fire during that await and reassign
activeTabId — losing the race meant the last-tab auto-create never ran,
leaving the manager with zero tabs. Capture wasActive before closing, and
only reassign activeTabId when it no longer points at a live tab.

* test(browse): delete the orphaned sidebar chat-queue suite; align sidebar-ux/tabs with the PTY-only sidebar

browse/test/sidebar-integration.test.ts tested the /sidebar-command queue
path ripped in v1.14 (34 references to removed endpoints — 11 permanent
failures masked by suite truncation). sidebar-ux.test.ts carried 73 failures
pinning the same dead surface (pickSidebarModel, ANALYSIS_WORDS); the trim
keeps its 108 live tests, including the background.js token/allowlist gates.
sidebar-tabs gets the two matching expectation updates.

* test(browse): align dual-listener and terminal-agent static guards with the current source

Two static-grep guards pinned superseded source shapes and failed once the
suite actually ran them: the tunnel dispatch gate is args-aware since the
--out disk-write ban (canDispatchOverTunnel takes command AND args), and
lazy PTY spawn routes through the maybeSpawnPty helper since v1.44. The
updated assertions pin the current, stricter shapes (open() never spawns;
the helper is the only spawnClaude caller).

* fix(test): remove all 8 delayed process.exit teardown bombs — the tier-1 gate can finally fail

bun test runs every file in ONE process, so a 500ms setTimeout(process.exit(0))
armed in afterAll fired mid-way through a LATER file and killed the entire
suite with exit 0 and no summary — only ~16 of 434 files ran, and every
downstream failure was invisible (observed live throughout this wave's
enumeration). Changes, all guarded by fault injection:

- Replace every delayed-exit teardown with a time-boxed close of the file's
  own browser (8 files across browse/ and design/); stub the daemon
  /shutdown timer instead of letting its unconditional process.exit tear
  the runner down.
- test/no-suicide-exit.test.ts: static tripwire — no *.test.ts may schedule
  a delayed process.exit again.
- test/exit-propagation.test.ts + fixtures: fault injection with REAL bun
  output proves the truncation shape (exit 0, no summary) and that
  scripts/test-free-shards.ts now detects it: a shard exiting 0 WITHOUT
  bun's final summary line is treated as FAILED (exit code alone is not
  evidence of completion).
- handoff: the three headed-mode integration tests are darwin-skipped with
  a pointer to the known macOS headed-launch breakage (#2242/#2554); they
  keep running on Linux CI. Un-skip in the browse-daemon wave.
- feedback-roundtrip: repair the handler call sites unmasked by the fix —
  handlers take (command, args, session, bm); passing the manager where a
  session belongs broke all six tests.
- user-slug-fallback: HOME isolation makes endpoint_hash deterministic.

Fixes #2421, #2435.

* test: include design/test/ in the free suite and the sharded runner

design/test was absent from both the package.json test globs and TEST_ROOTS

* fix(make-pdf): reject directories when resolving the browse binary

access(X_OK) is true for directories (they carry the execute/traverse
bit on POSIX and pass the Windows existence check too), so cwd-dependent
resolution could pick the ~/.claude/skills/browse alias DIRECTORY as the
browse binary. Every browse call then exited 4 with empty stderr, which
make-pdf surfaced as "Chromium failed to launch" against a perfectly
healthy Chromium (#2156). Guard isExecutable with statSync().isFile()

* fix(make-pdf): write browse-bound temp files under the safe-dirs allowlist

os.tmpdir() on macOS resolves to /var/folders/..., which fails browse's
safe-dirs validation ([/tmp, cwd]) since the v1.6.0.0 --from-file
tightening. Default PDF output (generate with no -o), the preview HTML,
tmpFile() scratch files, and setup's smoke-test fixture/output all wrote
there, so browse rejected the paths it was asked to read or write.
Export PAYLOAD_TMP_DIR from browseClient (the existing TEMP_DIR
convention: os.tmpdir() on Windows, /tmp elsewhere) and route
orchestrator.ts and setup.ts temp files through it.

* fix(make-pdf): stop URLs swallowing smartypants placeholders

A bare autolinked URL (<a href="X">X</a>) has zero whitespace between
the URL text and its own closing tag. TAG_RE carves that </a> into a
NUL-delimited SMARTPANTS_PRESERVED placeholder BEFORE the URL pass
runs, and URL_RE's \S+ swallowed the adjacent placeholder into the URL
match. The restore pass is single-shot, so the inner placeholder never
restored: raw "SMARTPANTS_PRESERVED_N" text leaked into the rendered
link, the </a> vanished, and link-blue styling bled into the rest of
the document (#2084). Excluding the NUL sentinel (\u0000) from the URL
character class stops the match from crossing into an already-carved
zone.

* fix(make-pdf): no blank first page when content precedes the first H1

Two paths put invisible content ahead of the first H1 and cost users a
blank page 1 (#1904):

- A visually-empty preamble (leading <style> block, HTML comment)
  became its own .chapter. That section took the `.chapter:first-of-type
  { break-before: auto }` exception, so the first real chapter inherited
  `break-before: page` and started on page 2. Non-rendering preambles
  now fold into the first real chapter (markup preserved, no page
  break); real text preambles keep their own chapter.
- Leading YAML frontmatter rendered as a literal paragraph of body text
  on its own first page (marked has no frontmatter awareness). It is
  now stripped before parsing; a `---` thematic break elsewhere is
  untouched.

* fix(browse): allow about:blank so a restarted daemon can initialise

The daemon opens its own first tab on about:blank, so blocking it in
validateNavigationUrl meant a restarted daemon could never recreate the
blank tab it starts from — and `browse newtab about:blank`, which
`make-pdf setup` runs as its Chromium smoke test, failed and surfaced
as "Chromium failed to launch" against a healthy browser.

Allow about:blank ONLY, never the about: scheme: about:blank has no
origin, loads nothing and runs nothing, while about:config and friends
are real surfaces. Exact href match (lower-cased, since the URL parser
normalises the protocol but not the opaque part), so about:blankfoo
stays blocked.

* fix(design): drop gpt-image-2 tool model that 400s under the gpt-4o orchestrator

The Responses API rejects pairing a gpt-4o orchestrator with an
image_generation tool spec'd as model: "gpt-image-2" (400
invalid_request_error), which took every design image call offline —
generate, variants, iterate (both threaded and fresh paths), evolve,
and /design-shotgun (#1771). gpt-image-2 is only valid under a gpt-5
orchestrator; with gpt-4o the tool must omit the model field (defaults
to gpt-image-1).

Remove the model field at all five call sites and add a static-grep
tripwire test (design/test/image-gen-pairing.test.ts) that fails CI if
any design/src module reintroduces the gpt-4o + gpt-image-2 pairing.
Re-enabling gpt-image-2 later requires bumping the orchestrator off
gpt-4o in the same diff, which the tripwire permits.

* fix(memory-ingest): stop silently ingesting 0 pages — include gitignored staging, reconcile counts

Pages stage into ~/.gstack/.staging-ingest-*/ inside a repo whose .gitignore
is `*`, and gbrain import honours .gitignore — so it collected 0 files,
imported nothing, and the ingest still reported "written: N" from the STAGED
count while advancing state, meaning no future run ever retried. Three
layers now: (1) pass --include-gitignored (root cause); (2) if the installed
gbrain predates the flag, retry without it (subcommand --help is generic, so
the attempt is the only probe) with an upgrade pointer; (3) reconcile
gbrain's imported+unchanged accounting against the staged count and REFUSE
to advance state on a shortfall, naming the gitignore collision.

* fix(session-update): un-wedge auto-upgrade — autostash over local patches, log the pull's real reason

On a normal install the tracked files ARE locally patched (skill-prefix
name rewrites, gbrain-refresh blocks), so the bare `git pull --ff-only`
refused on every run and auto-upgrade froze forever — observed as 308
consecutive PULL_FAILED entries with the reason discarded by 2>/dev/null.
Pull now runs --autostash (local patches ride over the update and pop back),
stderr is captured into the log so a genuine failure names its cause, an
autostash pop conflict recovers to a clean tree and re-renders the patches
(gstack-patch-names + gbrain-refresh, both idempotent), and a successful
pull re-renders them as a self-heal. Behavioral tests cover the wedge shape
and the reason logging.

bun's 5s default is fine for a file run solo, but the monolithic free suite

* fix(question-log): parse native AskUserQuestion answers — every native answer logged as __unknown__

Current Claude Code returns AskUserQuestion results as an OBJECT map keyed
by question text ({answers: {question: label}}); the hook only handled the
legacy array shapes, so 86% of live records carried user_choice __unknown__
— and the bin then scored every one as followed_recommendation false,
silently poisoning plan-tune metrics. Adds the object-map extraction (exact
+ whitespace-normalized + single-question pairing, multiSelect joins,
annotations as free_text), strips the (Recommended) suffix from BOTH sides
of the comparison, skips the computation entirely on extraction failure,
and logs unrecognized shapes to hook-errors.log instead of embedding them
in the record.

* fix(slug): resolve the project root by marker walk-up — subdirectory sessions stop misfiling state

gstack-slug derived everything from pwd, so a session in a subdirectory got
the subdir's basename as its slug (or an outer monorepo's remote), misfiling
reviews/decisions/learnings under a phantom project — and the per-pwd cache
made the wrong answer permanent. The resolver now walks up from pwd:
outermost STRONG marker wins (.git, package.json, pyproject.toml, Cargo.toml,
Gemfile, go.mod, .project.yaml), weak content markers (README, LICENSE) catch
non-code project folders, deploy artifacts are deliberately not markers, and
GSTACK_PROJECT_SLUG remains the escape hatch. The cache self-heals on
mismatch. Main-side invariants preserved on top: the unconditional
[a-zA-Z0-9._-] re-sanitize before echo and slash→dash branch canonicalization.

extensionless bash scripts directly (unrunnable without a shell association)

* fix(windows): grant icacls ACEs by *SID, not unqualified username

An unqualified username handed to icacls is ambiguous: on a machine whose
hostname equals the username (a common Windows setup), it resolves to the
MACHINE account instead of the user. Combined with /inheritance:r, that
leaves ~/.gstack with a single ACE matching nobody — the process that just
"secured" the directory locks itself out, and icacls still reports success.

Both icacls sites in the repo (restrictFilePermissions and
restrictDirectoryPermissions in browse/src/file-permissions.ts — the only
icacls call sites; setup has none) now grant via icacls' literal-SID form
`*<SID>`, resolved once per process from System32\whoami.exe (pinned to
System32 because a bare `whoami` under a bash-flavoured PATH picks up the
MSYS build, which rejects /user). Fallback when the SID can't be resolved
is the domain-qualified `USERDOMAIN\username` name, which is unambiguous
where the bare username was not.

Windows-only regression tests assert the hardened directory stays usable
by the calling process (readdir + write), which is exactly the check that
a not-toThrow assertion sailed past before.

* fix(windows): forward windowsHide through the bun-polyfill spawn shims

windowsHide is the one spawn option where Node's default is the opposite
of Bun's: Node shows the child's console window, Bun.spawn hides it.
The polyfill's spawn and spawnSync shims dropped the option entirely, so
the Node fallback path (dist/bun-polyfill.cjs) silently inverted the
behavior on the one platform the shim exists to serve — every watchdog
respawn of the terminal agent popped a visible bun.exe console window.

Three sites fixed:
- Bun.spawnSync shim: forwards windowsHide with Bun-matching default true
- Bun.spawn shim: same (stdio:'ignore' silences output but does NOT
  suppress the console window on Windows)
- spawnTerminalAgent in terminal-agent-control.ts: explicit
  windowsHide: true, so the Node fallback path behaves like Bun-native

An explicit windowsHide: false is honored at both shims. Three focused
tests pin the default-true, default-true-sync, and explicit-false paths
by intercepting child_process in a subprocess; the test file's require
path now uses forward slashes so it survives interpolation into a JS
string literal on Windows.

Supersedes PRs #2523, #2294 and #2290, which each covered a subset of
these sites.

* fix(watchdog): signal-0 liveness, tick-scaled respawn guard, windowsHide

Three-bug chain behind the Windows terminal-agent leak (console window
strobing every 60s, one orphaned agent per watchdog tick until the box
ran out of committable memory):

1. isProcessAlive shelled out to `tasklist /FI "PID eq <pid>"` on Windows
   with a 3s timeout. A Bun.spawnSync that hits its timeout still RETURNS
   with partial stdout, so the `.includes()` PID match read a LIVE agent
   as dead — killAgentByRecord skipped the kill, the watchdog respawned
   around the survivor, and every orphan slowed the next tasklist enough
   to produce the next false negative. Now: `process.kill(pid, 0)` on
   every platform (Node and Bun both map signal 0 to an OpenProcess
   existence check on Windows), with EPERM counted as alive. No
   subprocess, no timeout, no console window.

2. The respawn circuit-breaker was mathematically unreachable — verified
   in this tree: RESPAWN_GUARD_WINDOW_MS was a fixed 60_000 against a
   60_000ms default tick, and each tick pushes at most one respawn
   timestamp, so three pushes span ~120s and can never coexist inside a
   60s window (eviction is strict `>`, and setInterval drift plus
   per-tick work always ages the prior entry past the boundary). The
   guard could not fire at the default tick rate and a steady
   one-per-tick leak ran unbounded. The window now scales with the tick:
   max(60_000, tick * (RESPAWN_GUARD_MAX + 2)), so "3 crashes in quick
   succession → stop" holds at any tick value.

3. The tasklist probe popped a visible console per tick (no windowsHide).
   Removing the shell-out kills that site; the agent-spawn site itself
   already passes windowsHide: true (landed with the bun-polyfill
   windowsHide commit — PR #2414's terminal-agent-control.ts hunk is
   reconciled there rather than duplicated).

New browse/test/process-liveness-windows.test.ts pins all three: no
subprocess from the probe, a static tripwire against reintroducing
`tasklist` + `PID eq` liveness checks in src/, the spawnTerminalAgent
windowsHide + stdio contract, and the window-derived-from-tick
arithmetic. terminal-agent-watchdog.test.ts test 4 now pins the
window/tick relationship instead of the fixed literal that let this
ship. Also converts `new URL(import.meta.url).pathname` to
`import.meta.path` across the static-grep tests it touches — the
pathname form yields /C:/... on Windows and breaks path.resolve.

* fix(terminal-agent): tie agent lifetime to its owning browse server PID

The terminal agent is intentionally detached so it survives the
short-lived CLI launcher, but its real owner is the persistent browse
server. If that server crashed or was killed before running normal
shutdown, the agent was adopted by PID 1 and lived forever (#2019).

spawnTerminalAgent now requires an ownerPid and exports it to the agent
as BROWSE_OWNER_PID; all three spawn sites pass the server PID (cli.ts
cold-start, cli.ts supervisor respawn, server.ts watchdog). The agent
polls the owner with signal 0 every 15s (GSTACK_TERMINAL_OWNER_WATCHDOG_MS
to tune) on an unref'd timer and, when the owner disappears, exits
through the SAME cleanup path as an intentional SIGTERM shutdown — now
re-entrancy-guarded and also removing the terminal-internal-token file
alongside the port file and agent record.

Runtime test spawns a real agent tied to a throwaway owner process,
kills the owner, and asserts the agent exits and its discovery files
(terminal-agent-pid, terminal-port) are gone.

Reconciled with the watchdog commit's spawnTerminalAgent contract test
(process-liveness-windows.test.ts now passes ownerPid and pins the
BROWSE_OWNER_PID env forwarding).

Closes #2019.

* fix(windows): give the bun-polyfill spawn shim a real `exited` promise

Bun.spawn exposes `proc.exited` as a Promise resolving to the exit code.
The Node fallback shim (dist/bun-polyfill.cjs) returned no such field, so
every `await proc.exited` on the Windows path resolved instantly to
undefined — the Windows cookie picker (cookie-import-browser.ts races
proc.exited at three sites) read stdout before the child produced it and
silent-failed; browser-skill-commands and terminal-agent hit the same
class.

The shim now:
- drains stdout/stderr eagerly into capped in-memory buffers (Node's
  Readables are pull-based; without draining, a child writing past the
  OS pipe buffer blocks in write() and 'exit' never fires), replaying
  them as fresh single-shot Web ReadableStreams so reads work before or
  after awaiting exit;
- caps the buffer at 16 MB (GSTACK_SPAWN_MAX_BUFFER to override), still
  draining past the cap so a runaway child can't wedge or OOM;
- resolves `exited` with Bun-matching codes (exit code, 128+signal, 1 on
  spawn error) after both pipes finish, and resolves on 'error' too —
  Node fires 'error' without 'exit' when the binary is missing, which
  otherwise hangs the await forever.

Six tests pin exit codes, the read-after-exit ordering, spawn-failure
resolution, the buffer cap, and the large-output drain. Adapted to the
current test file (require path goes through the requirePath variable
from the windowsHide commit), and the 1 MB drain test's child now exits
in the write callback — on modern Node a pipe write past the OS buffer
is async and process.exit() straight after write() truncates at ~64 KB
even with a live reader, which fails the test for reasons unrelated to
the shim.

* fix(setup): BROWSE_BIN carries the .exe suffix on Windows

On Windows, `bun build --compile` emits browse.exe, but setup's
BROWSE_BIN pointed at the suffixless path — so the post-build gate
(`[ ! -x "$BROWSE_BIN" ]` → "browse binary missing") could never pass on
Windows even after a fully successful build, while the build step itself
reported success. Closes #2291.

Applied the PR's override after the IS_WINDOWS detection, and also to
the second BROWSE_BIN assignment the PR predates: the direct-Codex-
install migration path re-derives BROWSE_BIN from the migrated dir and
would otherwise drop the suffix again on Windows.

* fix(setup): link lib/ beside bin/ at all five host-install sites

bin/ scripts import shared modules via ../lib (gstack-learnings-log →
lib/jsonl-store.ts is the reported case), so any runtime root that
exposes bin/ without lib/ breaks 13 bin/ commands — learnings-log,
decision-log, telemetry and friends fail with "Cannot find module
.../lib/jsonl-store.ts" on every non-Claude install, silently from the
skills' perspective.

All five host-install sites now carry lib/ next to bin/, each through
the existing _link_or_copy helper (never raw ln — the static invariant
in test/setup-windows-fallback.test.ts enforces this):

- .agents sidecar (create_agents_sidecar asset loop)
- Codex runtime root (create_codex_runtime_root)
- Factory runtime root (create_factory_runtime_root)
- OpenCode runtime root (create_opencode_runtime_root)
- Kiro install block

New test/setup-runtime-lib-command.test.ts executes the real setup shell
for each root in a sandbox (both the symlink branch and the Windows copy
branch of _link_or_copy) and runs gstack-learnings-log end-to-end from
the installed root, asserting the learning lands in
~/.gstack/projects/<slug>/learnings.jsonl — plus a negative control
proving a bin-without-lib root fails exactly the way the bug report did.
gen-skill-docs.test.ts's setup-validation block pins the lib link at
every site. Cross-checked against PRs #2433, #2410 and #2198: all three
cover subsets of these sites; nothing they fix is missing here.

* fix(setup): ship supabase/config.sh with every host runtime root

Distinct from the lib/-beside-bin/ defect: gstack-telemetry-sync,
gstack-update-check, gstack-security-dashboard and
gstack-community-dashboard all source $GSTACK_DIR/supabase/config.sh to
resolve GSTACK_SUPABASE_URL, where GSTACK_DIR is the installed root
(parent of bin/). The [ -f ... ] guard means a root without the file
degrades SILENTLY — telemetry and update checks just stop resolving the
project URL on non-Claude installs. Closes #2215.

setup now links supabase/config.sh (file-level on purpose — migrations/
and functions/ are dev-only) via _link_or_copy at all five host-install
sites: the PR's four (Codex, Factory, OpenCode runtime roots + the Kiro
block) plus the .agents sidecar, whose bin/ resolves the same relative
path and which the PR predates covering.

The runtime-root test now asserts supabase/config.sh is present in
every built root, on both the symlink and Windows-copy branches.

* ci(windows): curate the fix-wave regression tests into the windows-latest run

The windows-free-tests curated set is derived (POSIX-fragility regex scan
+ explicit deny list), and two of this wave's Windows regression files
were auto-excluded on false-positive pattern hits:

- browse/test/file-permissions.test.ts tripped the POSIX-mode-bitmask
  pattern, but every `mode & 0o777` assertion is platform-guarded — and
  the file carries the win32-only icacls-by-SID regression tests, which
  can only ever execute on windows-latest.
- browse/test/terminal-agent-owner-watchdog.test.ts tripped the
  spawn(['bun','run',...]) pattern whose reason is the Playwright-bound
  browse server; it actually spawns terminal-agent.ts (fs/path/crypto +
  local helpers only, no Playwright at module scope), and the owner-PID
  orphan leak it pins was reported on Windows (#2019).

Adds a KNOWN_WINDOWS_SAFE force-include list (mirror of
KNOWN_WINDOWS_INCOMPATIBLE, each entry carrying its false-positive
rationale) consulted before the pattern scan, and makes the
owner-watchdog test's throwaway owner process Windows-portable
(process.execPath instead of `sleep`, which a bare runner may not have).

The wave's other new files need no wiring: process-liveness-windows and
the bun-polyfill windowsHide/exited tests pass curation automatically;
setup-runtime-lib-command self-skips on win32 by design (its Windows
branch is exercised by simulating IS_WINDOWS=1 under bash), so
force-including it would add a permanently-skipped file.

* fix(mktemp): move the X-run to the end of every temp-file template (BSD/busybox safe)

BSD mktemp (macOS) does not substitute an X-run that has a suffix after it:
`mktemp "$TMP_ROOT/codex-err-XXXXXX.txt"` creates a LITERAL
codex-err-XXXXXX.txt on the first call (exit 0) and every later call fails
with `mkstemp failed: File exists` — so /codex breaks from the SECOND run on
every Mac, masquerading as a model stall. busybox mktemp (Alpine) rejects the
template on the first run. Fixes #2091, #2370.

Union of both community fixes, compared at the diff level:
- PR #2372: all 11 source sites with a suffix after the X-run — codex
  SKILL.md.tmpl (5), claude SKILL.md.tmpl (3), bin/gstack-developer-profile
  (2, suffix folded into the prefix: .json.tmp.XXXXXX), and the office-hours
  codex pass in scripts/resolvers/review.ts (1).
- PR #2103: the second half of #2091 — bin/gstack-paths now strips the
  trailing slash from TMP_ROOT at the source (macOS $TMPDIR ends in `/`),
  plus runtime tests pinning that normalization.

New repo-wide tripwire in test/regression-issue2091-bsd-mktemp.test.ts:
every .tmpl, every SKILL.md, and every scripts/resolvers/*.ts is swept —
no mktemp template may carry a suffix after the X-run, with a self-test so
the detector can't be quietly blinded. Generated SKILL.md files regenerated

* fix(codex,review,ship): scope codex review with an explicit --base flag, never prompt text

`codex review` takes its scope ONLY from --base/--commit/--uncommitted. The
positional [PROMPT] is mutually exclusive with all three, and a prompt-only
`codex review "<text>"` silently falls back to the uncommitted working-tree
scope (verified on 0.144.1: it runs `git status --short; git diff` and
reviews that) — so the previous prompt-based scoping produced a
confidently-worded review of the WRONG changes and read "no changes" on a
clean tree. Every diff pass now invokes `codex review --base <base>` with no
prompt argument: /codex Step 2A default path, the /review structured pass,
and the /ship adversarial-section pass (all via scripts/resolvers/review.ts).

Custom review instructions keep their own `codex exec` path (the CLI rejects
prompt + scope flag together), with the filesystem boundary preserved there.
Two new Error Handling entries teach the failure shapes: the argv-parse
error, and the "review says no changes on a branch full of changes" symptom.

Tests updated to pin the new invariant instead of banning the fix: the old
assertions required the diff range in prompt text and banned the
`--base <base> -c '...'` substring, which the correct scoped form contains.
Also deletes test/fixtures/golden-ship-claude.md — a 2,565-line orphaned
fixture referenced by zero tests (the live goldens are in
test/fixtures/golden/, compared by test/host-config.test.ts); the factory
golden is refreshed from the regenerated output. Generated SKILL.md files

* fix(review,ship): run the codex diff passes under the timeout wrapper (#1036)

The `_gstack_codex_timeout_wrapper` added in #1056 was wired into
codex/SKILL.md but never into the /review and /ship diff passes, which kept
running under a bare 5-minute Bash gate. An unwrapped stall returns no exit
code and no output, which downstream reads as "Codex reviewed and found
nothing" — a truncated pass silently became a clean bill. Measured on
codex-cli 0.145.0: a pass was killed at 287s of a 300s budget mid-tool-call,
and the same prompt completed in 336s.

Both passes in scripts/resolvers/review.ts (adversarial `codex exec` and the
structured `codex review --base` pass) now re-source gstack-codex-probe and
run under `_gstack_codex_timeout_wrapper 540`, with the Bash tool gate raised
to 600000 ms so the wrapper fires FIRST and a stall surfaces as a diagnosable
exit 124. The timeout guidance now says a timed-out pass is MISSING COVERAGE,
not a clean result, and points at the run's rollout log under
~/.codex/sessions/ for partial output. The stale "timeout doesn't exist on
macOS" claim is gone — the wrapper resolves gtimeout, then timeout, then runs
unwrapped, so it is safe without coreutils.

Static guards in test/codex-hardening.test.ts pin all three sites (resolver,
review/SKILL.md, ship/sections/adversarial.md): both calls wrapped, wrapper
budget strictly under the Bash gate, and no reappearance of the macOS claim
that steered these call sites away from the wrapper in the first place. The
Claude-output path guard in test/gen-skill-docs.test.ts now scrubs
~/.codex/sessions/ (a user-facing Codex CLI path, same class as the
~/.codex/logs/ exemption) before banning Codex host paths. Generated files
regenerated via gen:skill-docs; factory golden refreshed.

* fix(codex): sandbox the review path, fail the gate closed, order timeouts wrapper-first

Closes #2496, #2524, #2477 — three defects in the class "a guard that
reports success while doing nothing", all in codex/SKILL.md.tmpl:

(a) Review sandbox. The default `codex review` path was the only codex call
with no sandbox override, inheriting ~/.codex/config.toml's default — write
access on a trusted project — while Important Rules claimed read-only.
Top-level `codex review` has no -s/--sandbox flag (verified on 0.147.0), so
the invocation now pins `-c 'sandbox_mode="read-only"'`, the same form the
consult-resume path already uses.

(b) Fail-closed verdict gate. The old rule ("no [P1] found → PASS") could
not fail on the default path: native `codex review` output carries no
bracketed tags, and a non-zero exit, expired auth, timeout, or empty result
also contains no [P1] — all read as PASS. The gate is now an ordered,
fail-closed check: non-zero exit → FAIL; empty output → FAIL; [P0]/[P1]
(bracketed or codex's native labels) → FAIL with count; NO severity tags at
all → FAIL requiring a human read; PASS is only reachable through the
explicit tagged-advisory-only branch. [P0] is recognized as blocking, and
the review-log findings count includes it.

(c) Bash gate above the wrapper. Step 2A instructed `timeout: 300000` under
a 330s wrapper, and Challenge's 300s gate sat under a 600s wrapper — the
harness killed the call before the wrapper could emit its diagnosable
exit-124 message. Every Bash gate now sits strictly ABOVE its wrapper:
360000 over the 330s review wrapper, 660000 over the 600s challenge/consult
wrappers, with the ordering rationale stated at each site.

Also from #2477/#2524: a new Error Handling entry for the model-entitlement
400 ("The '<model>' model is not supported...") pointing at the `model =`
pin and `[notice.model_migrations]` in ~/.codex/config.toml and saying
exactly which override to retry with (-m for exec-based modes,
`-c model="..."` for review mode, which rejects -m); the Model & Reasoning
section no longer documents `-m` for `/codex review`.

Static assertions in test/codex-hardening.test.ts pin (a)-(c) across both
the .tmpl and the generated SKILL.md: every scoped review invocation carries
sandbox_mode="read-only" and never -s; the default-PASS sentence is banned
and the fail-closed branches are present; and per-section, every Bash
`timeout: N` is strictly greater than every wrapper budget, with 2A/2B/2C
all required to be inspected. Generated SKILL.md regenerated via
gen:skill-docs in this commit.

* fix(browse): skip the .gitignore append when git already ignores .gstack/

ensureStateDir appended ".gstack/" to a tracked .gitignore even when git
already ignored the directory via global excludes, .git/info/exclude, or a
parent .gitignore — dirtying the working tree on every daemon start. Run
`git check-ignore -q -- .gstack/` first and return early when git says it's

* fix(browse): guard browser.process() in resolveDisconnectCause

`.process()` only exists on browsers Playwright launched itself; a browser
from connectOverCDP() (or a test stub) has no such method, so the blind call
threw "browser?.process is not a function" inside the disconnect handler and
took down the daemon. Type-check the method before calling it and treat the
no-method case as no process handle.

* fix(resolvers): stop env-var hosts from doubling $HOME in the binary fallback path

The browse/design/make-pdf setup resolvers built the fallback binary path as
"$HOME" + dir.replace(/^~/, ''), which is only correct for ~-rooted dirs.
Env-var hosts carry an absolute $GSTACK_* dir, so the generated fallback
became $HOME$GSTACK_.../browse — a path that never exists. New toShellPath()
in scripts/resolvers/types.ts expands ~ to $HOME and passes absolute
env-var dirs through untouched; all five call sites route through it.

* fix(browse): recover a late-healthy detached daemon instead of a false "Server failed to start"

startServer spawns the daemon detached + unref'd, then polls health for a
fixed budget. On a loaded machine the budget can elapse in the gap between
the loop's last tick and the daemon becoming ready — the CLI reported
"Server failed to start within Ns" while the very next `browse status`
showed a healthy server. Add a final readState()+isServerHealthy() re-check
before the timeout throw, and make the budget env-overridable via
BROWSE_START_TIMEOUT (BROWSE_* tunable convention). Structural + behavioral

* fix(browse): daemon resilience on loaded machines — Bun conn errors, stop/restart flush, startup + git-root budgets

Four load-sensitivity fixes in the daemon lifecycle:

- sendCommand only recognized Node's ECONNREFUSED/ECONNRESET; the compiled
  CLI runs on Bun, which reports 'ConnectionRefused'/'ConnectionClosed'
  ("Unable to connect..."), so daemon crashes leaked the raw error and
  exited 1 instead of entering the busy-check/restart path. Match both.
- stop/restart called shutdown() inline, which exits before the HTTP
  response flushes — the CLI saw a dropped socket (and would now
  crash-retry a fresh daemon just to stop it). Defer shutdown ~100ms so
  the 200 lands first.
- Non-CI POSIX startup budget raised 8s -> 15s (cold Chromium measured
  ~5.7s at load avg 10; load 12+ blew the old budget while the detached
  daemon was still booting).
- getGitRoot's 2s git rev-parse timeout returned null under load (6.3s
  spikes measured), scattering state files across cwds into split-brain
  daemons. Raise to 8s, still bounded.

The telemetry_events columns exist and bin/gstack-telemetry-log already

both fields on insert — every error report arrived with no message and no
failing step. Map them through with the same bounded-length sanitization as
error_class (500/100 chars). The completion-status resolver now also passes
--error-message/--failed-step in the generated skill telemetry block, with
instructions to leave them empty on success.

The walk-up rewrite recomputed the slug on every run and "healed" the cache

the remote-derived slug, orphaning everything under ~/.gstack/projects/.
Cached identity now wins, with one precise exception: when the cached value
equals THIS pwd's basename while the walk-up proves pwd is not the project
root, the entry came from the pre-walk-up subdirectory bug (#1125) and is
recomputed. All four slug contracts pass together (repo-mode #2212,
walk-up #1125, sanitize, user-slug).

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.

* 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.

* 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.

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.

* 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.

* 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.

* 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.

* fix(ci): harden Dockerfile.ci against transient Ubuntu mirror failures

The CI image build failed with:
  E: Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/...
     Connection failed [IP: 91.189.92.22 80]
  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.

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

* 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.

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

* 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.

* 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.

* 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.

* 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.

* 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).

* 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.

* 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

* 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\`.
