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.)

* 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

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

--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

* 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.

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

`.process()` only exists on browsers Playwright launched itself; a browser

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.

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()

env-var dirs through untouched; all five call sites route through it.

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

"Server failed to start within Ns" while the very next `browse status`

* 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.

* fix(slug): cached identity is sticky — heal ONLY the provable subdir-cache bug shape

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).

That is why every block read '+$0.00, +0s, Stable run, no regressions.'
This harness has never been able to detect a regression, and reassuring
output that cannot fail is worse than none. In-progress runs are now
excluded by role, and a run with nothing to compare against says NO
BASELINE instead of claiming stability.

* feat(evals): register shipped skills for hermetic PTY children

Hermetic children get a config dir that deliberately seeds no skills —
right for children that install their own, fatal for the PTY family that
TYPES /office-hours or /plan-ceo-review: claude rejects the command as
Unknown before any model turn, so the plan-family gate smokes measure
nothing. hermeticSkillsConfigDir() is a second, opt-in config dir under
the same runRoot that mirrors ./setup's registration exactly (real dir
per registry name, SKILL.md + sections/ symlinks, frontmatter-name
resolution, _gstack-command root alias), driven by the shared
skill-census so connect-chrome's dir symlink collapses the same way
setup's idempotent overwrite does.

Ported from fork commit 03c4eca2, tree walk rewritten for the upstream

* feat(evals): seedSkills opt-in for PTY slash-command tests + tripwire

Wire ClaudePtyOptions.seedSkills through launchClaudePty: when set (and
hermetic, and no per-test CLAUDE_CONFIG_DIR override), the child gets
hermeticSkillsConfigDir() so typed /skill slash commands resolve instead
of dying as Unknown command before any model turn. Opted in at the three
runPlanSkill* helpers and the four direct-launch slash-command tests
(plan-design-with-ui, plan-ceo-mode-routing, autoplan-chain,
ship-idempotency).

New static tripwire (test/pty-skill-seeding-wiring.test.ts): any test
file that sends a slash command over the PTY must route through a
runPlanSkill* helper or pass seedSkills: true — an unseeded slash-command
test spends money and measures nothing. hermetic-wiring.test.ts now
blesses the repo-tree seeding path explicitly (config dir under runRoot,
symlinks into the repo checkout, never operator ~/.claude).

The CI "Register gstack skills for PTY smoke" step keeps a keep-me note:
container cross-mount symlinks defeat the TUI scanner and HOME is not
hermeticized, so the real-file copies there must survive this change.

scripts/test-free-shards.ts derives its free/paid exclusion from it
instead of a private regex list, dropping the dead
browse/test/security-review-fullstack.test.ts pattern (file no longer

module, so a file added to one list can no longer silently miss the
other.

* feat(evals): env-driven lazy eval dir + shard-aware store and tooling

Importing eval-store no longer spawns the gstack-slug subprocess: the
module-level DEFAULT_EVAL_DIR constant is now a memoized defaultEvalDir()
resolved at collector construction. Resolution order: explicit
constructor arg, then GSTACK_EVAL_DIR, then slug detection — so the
sharded paid runner can point each shard child at its own
<evalDir>/shards/<slug>/ dir with plain env, no --preload.

Runs collected under a shards/ subdir record their slug in the eval
JSON (EvalResult.shard). findPreviousRun scans one shards/<slug>/ level
and prefers same-slug priors, so each shard baselines against its own
history instead of whichever shard flushed last. eval:list,
eval:summary, and eval:compare enumerate the same one level of shard
subdirs; eval:compare's no-arg mode also stops picking an in-progress
accumulator as the after-run.

eval-watch stays flat (documented follow-up): it tails a single dir for
live progress and gains nothing from per-shard baselines until the
runner emits a merged stream.

* feat(evals): sharded paid tier runner

scripts/test-paid-shards.ts runs the gate/periodic tier one Bun process
per test file, with an EXTERNAL wall-clock timeout that SIGKILLs the
shard's detached process group and an aggregate that distinguishes
passed / failed / timed-out / never-started — partial execution can no
longer read as a pass. Bun's native --shard/--isolate covers none of
this: no process-group kill (hung claude/codex PTY grandchildren
survive in-process isolation), no never-started taxonomy, no per-shard
env. Each shard child gets GSTACK_EVAL_DIR=<evalDir>/shards/<slug>/
(slug = test filename sans extension, stable across runs) so shard
baselines compare against their own prior runs.

Output classification lives in scripts/test-strict-output.ts (strict
exit-code derivation, incremental fail-line classifier, child signal
forwarding) so the runner and any future strict bun-test wrapper share
one implementation. Enumeration derives from the shared paid-test-set
module; tier exclusion fires only on an explicit whole-file
EVALS_TIER === '<other>' guard.

package.json gains test:gate:sharded / test:periodic:sharded, and
eval:bg:gate / eval:bg:periodic now run the sharded scripts with detach
timeouts sized to the worst case (gate: 49 shards x 30min / 4 jobs ~
6.2h -> 25200s; periodic: 59 -> 28800s).

test/paid-shards.test.ts pins enumeration, tier classification, and the
kill-and-continue property with a real busy-loop shard.

* feat(security): hash-chained egress receipt ledger (core)

Port lib/egress-receipt from the v2 fork as TypeScript: writeReceipt
(sync, fail-closed via typed EGRESS_RECEIPT_FAILED), best-effort
writeOutcome, readLedger/listReceipts/verifyLedger, GSTACK_HOME ->
GSTACK_STATE_DIR -> ~/.gstack resolution, 0600 ledger under a 0700
security dir, and an mkdir spin lock (2.5s budget) with documented
>10s-mtime stale-lock reclaim.

Changes vs the fork:
- lastRawLine tail-reads the final 4KB instead of loading the whole
  ledger, so appends stay O(1) as the file grows.
- WARN-at-size: past 25MB writeReceipt emits one self-explanatory
  stderr warning per process (what the ledger is, how to inspect it,
  rotation TODO); verifyLedger gains a sizeWarning field. Rotation
  TODO carries the chain-genesis sketch (new generation's first record
  embeds the prior file's tail hash).

bin/gstack-egress-receipt is a bun script bridging shell callers:

* chore(bin): delete dead brain-consumer/reader scripts

bin/gstack-brain-consumer and bin/gstack-brain-reader are byte-identical
dead scripts that POST the repo URL + a Bearer token to a /ingest-repo
endpoint gbrain removed (docs/gbrain-sync.md already documents the
removal in past tense). No live references remain; CHANGELOG mentions
are historical.

* feat(security): shared shell receipt helpers

bin/gstack-egress-lib.sh (sourced library, gstack-gbrain-lib.sh
precedent) provides _receipted_curl and _receipted_git: write the
egress receipt BEFORE the send via gstack-egress-receipt, hand curl the
SAME payload file via --data-binary @file so the receipt hash matches
the wire bytes exactly, then append a best-effort outcome. Per-call
fail policy: 'closed' refuses the send (return 3, problem/cause/fix
message on stderr) and 'open' warns and proceeds. Payload temp files
are consumed immediately per call — no EXIT traps, since callers like
gstack-telemetry-sync own their own EXIT trap and a sourced trap would
clobber it.

Tested end-to-end against a local Bun.serve listener: receipt sha256
equals the sha256 of the bytes the listener received, fail-closed
refusal never touches the network and carries the problem/cause/fix
stderr shape, fail-open warns and proceeds.

* feat(security): receipt core shell sinks

Wire the three core bash egress sinks through gstack-egress-lib.sh:

- gstack-telemetry-sync: the batch POST now writes the payload to a
  temp file, receipts those exact bytes fail-closed, and hands curl the
  SAME file. On refusal nothing is sent and the cursor does not
  advance, so the batch stays buffered for the next run. The HTTP
  status is recorded as the receipt outcome.
- gstack-update-check: fail-open receipts (warn + proceed) on the
  Supabase ping POST, both VERSION curls (via a local
  _receipted_version_fetch helper that skips non-network schemes), and
  git ls-remote. The ping receipt is written inside the backgrounded
  subshell, so it can never block the script's exit.
- gstack-brain-sync: fail-closed git-class receipts. The push receipt
  is written BEFORE the commit consumes the queue, so a refused receipt
  leaves the queue intact and the next run retries the whole drain
  (pinned by a new queue-intact-on-refusal test, including the
  problem/cause/fix refusal message shape). The retry-path fetch and
  retry push carry their own fail-closed receipts.

* feat(security): receipt TS module sinks + tunnel

writeReceipt (fail-closed, sha256:null — a subprocess or SDK owns the
wire bytes) before every TS-module network-bearing operation:

- bin/gstack-gbrain-sync.ts: before the gbrain code walk that ships
  repo content to the user's gbrain DB (may be remote Postgres). A
  refused receipt fails the stage with status refused-egress-receipt.
- bin/gstack-memory-ingest.ts: before the gbrain batch import of
  transcript pages. A refused receipt returns a system_error verdict
  without spawning the import.
- browse/src/server.ts: before both ngrok.forward call sites (start-up
  BROWSE_TUNNEL=1 path and the /tunnel/start endpoint). A receipt
  failure lands in the existing catch that tears the tunnel listener
  back down and refuses the start.

* feat(design): receipted fetch for OpenAI calls

design/src/receipted-fetch.ts wraps every api.openai.com call: a
content-free egress receipt (sink design-openai, sha256 of the JSON
body — hash only, never the body) is written BEFORE the send. Polarity
is FAIL-OPEN: user-facing generation must not die because an audit log
hiccuped, so a receipt failure warns on stderr and the call proceeds.
Streams pass through untouched (response bodies returned as-is;
non-string request bodies receipted as sha256:null rather than drained
to hash).

All ten call sites converted with per-command payload classes:
generate, variants (injected fetchFn passes through), iterate (both
threaded and fresh paths), evolve (image + screenshot analysis), check,
diff, design-to-code, memory.

Unit-tested with injected fetch: receipt-before-send ordering, stream
passthrough, and fail-open on an unwritable ledger.

* feat(security): receipt admin scripts + user git-ops (zero exceptions)

Wire the remaining shell egress through gstack-egress-lib.sh:

- gstack-gbrain-mcp-verify: both JSON-RPC probe POSTs (initialize +
  tools/list) receipted fail-closed via payload files (hash == wire
  bytes). A refused receipt lands in the NETWORK class — no send.
- gstack-security-dashboard / gstack-community-dashboard: the
  community-pulse GETs receipted fail-open (read-only stats must not
  break over an audit hiccup).
- gstack-gbrain-supabase-provision: api_call receipted fail-closed.
  Each retry attempt hands the helper a fresh copy of the body file
  (the helper consumes its payload). The receipt hashes the request
  body only — the PAT never reaches the ledger or any log. Refusal
  exits 8 without retrying.
- git-class sha256:null receipts, fail-open: gstack-artifacts-init
  (ls-remote, initial push, fetch/pull recovery, retry push),
  gstack-brain-restore (staging clone, existing-repo fetch),
  gstack-session-update (self-update pull).

gstack-team-init needs no wiring: every git clone in it is inside an
echoed instruction string, not an executed command.

The lib now self-locates with shell builtins only (no dirname), so
sourcing works under the whitelist-PATH test harnesses.

* test(security): egress wiring tripwire + polarity contract

Static-grep tripwire pinning the egress-receipt wiring (threat model in
the header: the ledger is forensic observability of ATTEMPTED egress,
not an exfiltration control):

- Per-sink assertions: every wired TS module imports egress-receipt and
  calls writeReceipt; every wired shell sink sources
  gstack-egress-lib.sh with each network op under a receipt;
  ngrok-proximity check for server.ts; every design api.openai.com call
  routes through receiptedFetch.
- Absence assertions: the dead brain-consumer/reader scripts stay
  deleted (lstat, so a dangling symlink also fails).
- Polarity table pinned as data (fail-closed: brain-sync,
  memory-ingest, gbrain-sync, telemetry-sync, ngrok, mcp-verify,
  supabase-provision; fail-open: design-openai, update-check,
  dashboards, git-class user ops, context-bill --exact) plus per-file
  polarity spot-checks.
- NEW-SINK SCANNER with zero KNOWN_UNWIRED: sweeps bin/, lib/,
  scripts/, design/src, browse/src for curl, absolute-URL fetch(, and
  git remote ops (never local rev-parse/get-url; heredoc bodies and
  message strings excluded) and requires every hit to be receipted or
  in a REASONED exemption list where each entry carries its why.
  Preamble-generated skill prose documented out-of-scope in the header.
- Shebang tripwire: no bin/gstack-* file may carry a node shebang.

* feat(cli): gstack-egress reader

bin/gstack-egress (bun) — the auditor's view of the receipts ledger:

- list: one row per receipt (what gstack ATTEMPTED to send), with
  --since/--host/--sink filters and --json.
- verify: recompute the hash chain; exit 3 on tamper naming the first
  broken line; prints the sizeWarning when the ledger passes 25MB.
- grants: what CAN leave, built on the upstream config keys only
  (telemetry, artifacts_sync_mode, redact_repo_visibility,
  redact_prepush_hook via gstack-config get) — each grant names its
  file, key, and the exact revoke command.

CLI smoke tests spawn the real bin against a temp GSTACK_HOME,
including a broken-chain fixture asserting exit 3.

* feat(cli): context-bill — token bill-of-materials (stripped port)

lib/context-bill.ts, ported from the v2 fork and STRIPPED to the tiers
this repo's skills can exercise: ALWAYS-ON (per-skill frontmatter bytes
with dead-key and foreign-host-file flags), EAGER (SKILL.md + any
forced 'for every invocation' references), on-disk totals, --diff,
--budget, and --exact with the calibration table. The fork's
CONDITIONAL/TRANSITIVE/LAZY/FAST-PATH parsers understand only its
dispatcher layout and were dropped; the tier fields stay in the report
shape (empty/zero/null) so re-adding a parser is additive.
TOKEN_DIVISORS and their provenance docblock kept; --help notes
recalibration via --exact's calibration block.

Three upstream fixes over the fork:
(a) findSkillDirs treats the walk ROOT as a container — the repo root's
    router SKILL.md is billed AND its children are walked (the fork
    short-circuited and billed one skill); walkMd skips node_modules
    and dot-directories.
(b) installed-tree layout: subdirs that are their own repo checkout
    (a gstack/ clone inside ~/.claude/skills, detected by .git) are
    skipped, and directory symlinks (connect-chrome) are followed with
    a container-recursion cycle guard.
(c) ROUTER_KEYS widened to the upstream frontmatter contract {name,
    description, version, allowed-tools, triggers, preamble-tier}.

--exact writes an egress receipt (sink context-bill-exact, host
api.anthropic.com) BEFORE any count_tokens POST; if the receipt cannot
be written the run degrades to the offline estimate with a warning —
nothing is sent unrecorded. bin/gstack-context-bill is the bun shim.

Tests: fixture-tree ledgers, the three fixes, --diff/--budget exit
codes, --exact with injected fetch (envelope subtraction, receipt
ordering, fail-open degradation), CLI smoke test, and ground truth
against THIS repo via test/helpers/skill-census.ts.

* test(catalog): aggregate discovery-surface budget with ratchet protocol

Every host loads every skill's frontmatter name + description at
discovery, every session. applyCatalogTrim in scripts/gen-skill-docs.ts
shapes each description and the 160KB per-file warn covers body size,
but nothing capped the aggregate frontmatter — the catalog could grow
one reasonable-looking description at a time. This test is that
enforcement layer.

Measures the catalog via test/helpers/skill-census.ts authoredSkills
(symlink-deduped, root router counted separately as the _gstack-command
alias line item): 53 skills + router = 4,420 bytes = 1,105
token-equivalents today, asserted <= 1,150 (~4% headroom). Per-skill
sub-cap of 260 bytes (largest today: design-consultation at 229), plus
a non-empty-description check.

Failure messages are self-service ratchets: they print the new total,
the delta, and the update protocol (bump the constant AND the
derivation comment in the same commit; trim instead of grow for
existing descriptions). Parser handles folded block scalars
(description: >-) for fork parity; import-free by design so it
survives generator refactors.

* fix(browse): extension token bootstrap moves to pinned-origin POST; /health carries no token

GET /health is now liveness/status only in every mode — both token
carve-outs (headed-mode disjunct AND chrome-extension:// Origin
disjunct) are removed. Token bootstrap is POST /extension-token on the
local listener: the Origin header must be exactly
chrome-extension://<GSTACK_EXTENSION_ID> and the Host header's hostname
must parse to 127.0.0.1 or localhost (parsed via new URL, never literal
equality — Host arrives as '127.0.0.1:34567'). Wrong origin/host → 403
with no detail. The tunnel surface 404s the endpoint (not in
TUNNEL_PATHS, verified by test).

The extension ID is pinned by a new "key" field (RSA public key) in
extension/manifest.json; browse/scripts/extension-id.ts reproduces the
ID derivation (first 16 bytes of SHA-256 of the DER public key, hex
mapped 0-9a-f → a-p). The private key is not committed anywhere —
unpacked/baked-in loads only need the public key.

Extension side: background.js bootstraps and refreshes the token via
POST /extension-token (403 → disconnected state); sidepanel.js direct
connect path does the same; sidepanel-terminal.js's dead /health token
fallback (read AUTH_TOKEN/authToken keys the server never sent,
hardcoded port) is replaced with the window.gstackAuthToken path.

MIGRATION NOTE: the manifest key pins the extension ID, so existing
installs' side-panel local state (saved port, snoozes) resets once —
explained in-product via a one-time notice (flag
gstack_id_migrated_v162). After upgrading the server, restart the
browser so the old service worker stops polling for a token GET /health
no longer serves.

* docs: correct stale compiled-binaries claim; file three egress/eval follow-ups

CLAUDE.md's compiled-binaries section claimed browse/dist binaries are
tracked by git and appear as modified in git status — false since
64d5a3e4 (v0.11.16.0) untracked them, and actively harmful: it trained
agents to ignore dist binaries in git status. The section now states
the truth (untracked + gitignored; a dist binary in git status means
someone force-added it) and covers make-pdf/dist too.

TODOS.md gains the three follow-ups filed by the v1.62 port-wave
reviews: ledger rotation with chain-genesis records, launch-nonce
token bootstrap, and eval-watch shard-awareness.

* fix: pre-landing review fixes for the v2 port wave

Review army (checklist + 5 specialists) + coverage/plan audits on the
assembled branch. Genuine correctness/security/hygiene fixes:

- test-paid-shards: strictTestExitCode now receives expectedFiles on the
  real bun path, so a shard that runs fewer files than planned (harness
  crash, nothing loaded) with exit 0 is no longer recorded 'passed' — the
  invisible-non-execution class the runner exists to kill. Pinned by the
  new test/strict-output.test.ts (also covers the chunk-boundary classifier).
- test-paid-shards: EVALS_TIER env is validated (gate|periodic) like the
  --tier flag, so a typo can't self-skip every test and exit 0 green.
- package.json: test:periodic:sharded sets EVALS_ALL=1, restoring the
  full-tier semantics the pre-shard script had (CI already set it; local
  eval:bg:periodic silently under-measured without it).
- brain-sync.test: run() pins HOME to the temp home so gstack-artifacts-init
  stops writing/clobbering the operator's real ~/.gstack-artifacts-remote.txt
  every free-suite run; afterEach now also scrubs the current filename.
- egress-receipt: cap each receipt field at 512B so a serialized line always
  fits the 4KB tail-read window — a longer line would make the next append
  hash a truncated prior line and verifyLedger report a permanent false
  TAMPER. warnLedgerSize short-circuits before statSync once fired (append
  hot path).
- gstack-egress: import.meta.dir (Windows-safe) instead of new URL().pathname
  so grants doesn't silently report defaults on Windows; strip control chars
  from ledger-derived fields on render so a crafted receipt can't spoof the
  auditor's view.
- extension/background.js + CLAUDE.md: renumber the identity-pin migration
  refs v1.62 -> v1.63 (main claimed 1.62.0.0; this wave queue-advances).
- egress-receipt-wiring: pin lib/context-bill.ts unconditionally (both land
  together now); drop the dead RunShardsOptions.tier field.

All fix-affected test files green; gate failures triaged as external-env
(codex/gemini CLI drift) or pre-existing (hermetic-canary fails identically
on base). Deferred polish tracked in the PR body + decision store.

* docs: file TODO to harden plan-design-with-ui PTY detection

The v1.63 seedSkills change made this gate test execute for the first
time; it reliably times out because its terminal scraper can't parse the
(correctly-rendered) scope-gate AskUserQuestion out of a spinner-mangled
PTY buffer. Shipped skill behavior is correct — test-harness limitation.

* chore: re-slot release as v1.62.1.0 (PATCH per user)

Main claimed 1.62.0.0 while the wave was in flight; the user chose the
PATCH slot over queue-advancing MINOR. Renumbers the identity-pin
migration notice (now version-free flag name so a re-slot never orphans
an already-set flag), the CLAUDE.md /health note, the CHANGELOG heading,
and the TODOS section titles.

* fix(test): stop hard-requiring the literal ok) case label in gbrain-refresh guards

The extractor grepped for 'ok)' but the case label grew to
ok|timeout|thin-client) (#1964, #2051), so the whole file errored on
import — the free suite's only red for months. The extractor now matches
any label starting with ok and its alternations; all 7 guard assertions
run again.

* fix(test): hermetic-canary probes with ${VAR:-} so nounset shells can't fail success

The probe echoed bare $CONDUCTOR_WORKSPACE_PATH — when scrubbing WORKS
the var is unset, and under a nounset shell the echo errors, failing the
canary exactly when isolation succeeds. Defaulted expansions assert
identically under any shell. Fails identically on base; fixed here.

* fix(evals): absorb codex/gemini CLI drift; external-service tests go periodic-tier

- codex exec gains --skip-git-repo-check: newer CLIs refuse exec in an
  untrusted non-git dir (our temp skill dirs) — empirically verified.
- gemini: --skip-trust was removed in gemini-cli 0.34 (argv parse error);
  dropped from the session runner and the benchmark adapter. A present-
  but-unusable CLI (deprecated individual code-assist auth path) now
  classifies as SKIP, not a false adapter failure; the benchmark live
  smoke skips on auth/rate_limit error codes (environmental) while still
  failing on timeout/unknown (the drift classes it exists to catch).
- codex-e2e, gemini-e2e, and benchmark-providers gain the canonical
  whole-file EVALS_TIER === 'periodic' guard per CLAUDE.md tiering rule 3
  (external service -> periodic) — the sharded gate runner now excludes
  all three (gate: 45 -> 42 shards).

* fix(evals): parse single-logical-line AskUserQuestions in the PTY runner

When the PTY reflows a boxed AUQ, ALL options land on ONE logical line
after stripAnsi — parseNumberedOptions parsed one option per line, found
only '1.', and the >=2 check failed forever while the correct question
sat on screen (plan-design-with-ui timed out this way twice, with the
rendered scope-gate AUQ visible in both failure buffers). The cursor
line is now parsed as a stream of ascending N. tokens; DEC cursor-
visibility residue is stripped before matching; plan-design-with-ui's
budgets grow to fit observed ~6min preamble+thinking latency. Pinned by
test/pty-auq-single-line.test.ts using the real failure buffers; all 142
existing parser-consumer unit tests still green.

* chore: restore v1.63.0.0 (MINOR — user-confirmed final slot)

The wave ships new capability (egress receipts + two CLIs, sharded paid
runner, hermetic skill seeding) at ~8K lines — MINOR scale per the
scale-aware bump rules. Supersedes the brief v1.62.1.0 re-slot; the
version-free migration flag means no state churn from the renumber.

Rename test/pty-auq-single-line.test.ts to

AskUserQuestion in full in filenames, identifiers, and comments.

* docs: sync every doc surface with the v1.63 release

/document-release audit (4-lane, all claims verified against branch code):

- README: gstack-egress + gstack-context-bill rows in the standalone-binaries
  table; Privacy & Telemetry gains the receipted-egress bullet (attempted-
  egress framing per the shipped threat model).
- ARCHITECTURE: /health is liveness-only, POST /extension-token endpoint row
  + bootstrap mechanics paragraph; new Egress receipt ledger subsection under
  Security model; eval persistence covers the sharded runner, GSTACK_EVAL_DIR,
  and the finalized-run baseline rule.
- CLAUDE.md: sharded test scripts in Commands; sharded semantics in the
  detached-evals section; PTY skill seeding in the hermetic section; egress
  invariant block beside the other server-egress invariants; catalog-budget
  ceiling beside the 160KB token ceiling; project-tree entries for
  lib/egress-receipt.ts, lib/context-bill.ts, scripts/test-paid-shards.ts.
- CONTRIBUTING: seedSkills + live-tree seeding in the hermetic paragraph;
  sharded runner in detached runs; catalog-budget in the Tier 1 list.
- BROWSER: extension token bootstrap section, tunnel egress receipts section,
  identity-pin migration note in manual install.
- REMOTE_BROWSER_ACCESS: tunnel-start receipt bullet in the security model.
- gbrain docs: /sync-gbrain + brain-sync egress-receipt behavior documented;
  dead consumer-token instructions removed (consumer machinery deleted this
  release); new fail-closed refusal added to the error catalog.
- CHANGELOG: measured-vs-ceiling catalog numbers, contributor notes for the
  external-service tier move and the PTY single-line AskUserQuestion parser,
  release date.
- TODOS: /health token-distribution TODO resolved by this release, removed;
  port-wave follow-up sections re-labeled to the shipped version.

* docs: sweep drift that predates this release

Surfaced by the /document-release audit; every fix verified against the
current binaries:

- gstack-brain-init was replaced by gstack-artifacts-init in v1.27.0.0
  (hard-delete, no compat shim), but README, USING_GBRAIN_WITH_GSTACK,
  docs/gbrain-sync.md, and docs/gbrain-sync-errors.md still instructed
  users to run it — command-not-found on every follow. Same sweep updates
  ~/.gstack-brain-remote.txt to the canonical ~/.gstack-artifacts-remote.txt
  (legacy name still honored on restore, noted where users copy the file).
- gbrain-sync-errors.md headings re-matched to the literal messages the
  binaries print today (the doc's whole value is grep-by-exact-message):
  'gstack-artifacts-init: ~/.gstack/ is already a git repo pointing at:',
  'Remote not reachable via SSH:', 'Failed to create or find ...'. The
  already-a-repo fix now leads with the command's own set-url suggestion.
- docs/gbrain-sync.md 'Under the hood' linked a plan file that does not
  exist in the repo; replaced with the decisions themselves.
- SIDEBAR_MESSAGE_FLOW startup timeline: /pty-session responds with
  {terminalPort, sessionId, attachToken, leaseExpiresAt} (v1.44 shape,
  verified at browse/src/server.ts:1860), not the retired
  {terminalPort, ptySessionToken} pair.

* docs: fold the Codex accuracy review of the release docs

Six findings, all verified against source before fixing:

1. 'Every send writes a receipt' overclaimed — fail-open sinks proceed with
   a stderr warning when the receipt write fails, so a fail-open send can go
   unrecorded (lib/egress-receipt.ts:8-14). Descriptive prose now says so;
   the receipted framing keeps 'attempted'.
2. 'Receipts hash the request body' is wrong for subprocess-owned sends —
   git pushes record sha256: null (lib/egress-receipt.ts:71).
3. 'grants shows every consent in force' overclaimed — it reports the four
   standing config settings (bin/gstack-egress:139-181). Reworded in
   README, ARCHITECTURE, and the CHANGELOG entry.
4. 'Zero-exception scanner' vs reality: the new-sink scanner carries a
   reasoned SCANNER_EXEMPT list (user-directed fetches, probes, instruction
   strings, skill prose). CLAUDE.md now names it.
5. Error-catalog cause/fix for the receipt refusal: the writer mkdirs the
   ledger dir itself, so 'missing' isn't a cause and bare chmod fails when
   it is absent — cause reworded, fix is mkdir -p && chmod.
6. gbrain-sync first-run steps described the retired binary's behavior:
   default repo is gstack-artifacts-$USER, and init PRINTS the gbrain
   hookup command (never auto-executes; bin/gstack-artifacts-init:384-419).

feat: gstack browser sidebar = interactive Claude Code REPL with live tab awareness (v1.14.0.0) (#1216)
* build: vendor xterm@5 for the Terminal sidebar tab

Adds xterm@5 + xterm-addon-fit as devDependencies and a `vendor:xterm`
build step that copies the assets into `extension/lib/` at build time.
The vendored files are .gitignored so the npm version stays the source
of truth. xterm@5 is eval-free, so no MV3 CSP changes needed.

No runtime callers yet — this just stages the assets.

* feat(server): add pty-session-cookie module for the Terminal tab

Mirrors `sse-session-cookie.ts` exactly. Mints short-lived 30-min HttpOnly
cookies for authenticating the Terminal-tab WebSocket upgrade against
the terminal-agent. Same TTL, same opportunistic-pruning shape, same
"scoped tokens never valid as root" invariant. Two registries instead of
one because the cookie names are different (`gstack_sse` vs `gstack_pty`)
and the token spaces must not overlap.

No callers yet — wired up in the next commit.

* feat(server): add terminal-agent.ts (PTY for the Terminal sidebar tab)

Translates phoenix gbrowser's Go PTY (cmd/gbd/terminal.go) into a Bun
non-compiled process. Lives separately from `sidebar-agent.ts` so a
WS-framing or PTY-cleanup bug can't take down the chat path (codex
outside-voice review caught the coupling risk).

Architecture:
- Bun.serve on 127.0.0.1:0 (never tunneled).
- POST /internal/grant accepts cookie tokens from the parent server over
  loopback, authenticated with a per-boot internal token.
- GET /ws upgrades require BOTH (a) Origin: chrome-extension://<id> and
  (b) the gstack_pty cookie minted by /pty-session. Either gate alone is
  insufficient (CSWSH defense + auth defense).
- Lazy spawn: claude PTY is not started until the WS receives its first
  data frame. Idle sidebar opens cost nothing.
- Bun PTY API: `terminal: { rows, cols, data(t, chunk) }` — verified at
  impl time on Bun 1.3.10. proc.terminal.write() for input,
  proc.terminal.resize() for resize, proc.kill() + 3s SIGKILL fallback
  on close.
- process.on('uncaughtException'|'unhandledRejection') handlers so a
  framing bug logs but doesn't kill the listener loop.

Test-only `BROWSE_TERMINAL_BINARY` env override lets the integration
tests spawn /bin/bash instead of requiring claude on every CI runner.

Not yet spawned by anything — wired in the next commit.

* feat(server): wire /pty-session route + spawn terminal-agent

Server-side glue connecting the Terminal sidebar tab to the new
terminal-agent process.

server.ts:
- New POST /pty-session route. Validates AUTH_TOKEN, mints a gstack_pty
  HttpOnly cookie via pty-session-cookie.ts, posts the cookie value to
  the agent's loopback /internal/grant. Returns the terminalPort + Set-Cookie
  to the extension.
- /health response gains `terminalPort` (just the port number — never a
  shell token). Tokens flow via the cookie path, never /health, because
  /health already surfaces AUTH_TOKEN to localhost callers in headed mode
  (that's a separate v1.1+ TODO).
- /pty-session and /terminal/* are deliberately NOT added to TUNNEL_PATHS,
  so the dual-listener tunnel surface 404s by default-deny.
- Shutdown path now also pkills terminal-agent and unlinks its state files
  (terminal-port + terminal-internal-token) so a reconnect doesn't try to
  hit a dead port.

cli.ts:
- After spawning sidebar-agent.ts, also spawn terminal-agent.ts. Same
  pattern: pkill old instances, Bun.spawn(['bun', 'run', script]) with
  BROWSE_STATE_FILE + BROWSE_SERVER_PORT env. Non-fatal if the spawn
  fails — chat still works without the terminal agent.

* feat(extension): Terminal as default sidebar tab

Adds a primary tab bar (Terminal | Chat) above the existing tab-content
panes. Terminal is the default-active tab; clicking Chat returns to the
existing claude -p one-shot flow which is preserved verbatim.

manifest.json: adds ws://127.0.0.1:*/ to host_permissions so MV3 doesn't
block the WebSocket upgrade.

sidepanel.html: new primary-tabs nav, new #tab-terminal pane with a
"Press any key to start Claude Code" bootstrap card, claude-not-found
install card, xterm mount point, and "session ended" restart UI. Loads
xterm.js + xterm-addon-fit + sidepanel-terminal.js. tab-chat is no
longer the .active default.

sidepanel.js: new activePrimaryPaneId() helper that reads which primary
tab is selected. Debug-close paths now route back to whichever primary
pane is active (was hardcoded to tab-chat). Primary-tab click handler
toggles .active classes and aria-selected. window.gstackServerPort and
window.gstackAuthToken exposed so sidepanel-terminal.js can build the
/pty-session POST and the WS URL.

sidepanel-terminal.js (new): xterm.js lifecycle. Lazy-spawn — first
keystroke fires POST /pty-session, then opens
ws://127.0.0.1:<terminalPort>/ws. Origin + cookie are set automatically
by the browser. Resize observer sends {type:"resize"} text frames.
ResizeObserver, tab-switch hooks, restart button, install-card retry.
On WS close shows "Session ended, click to restart" — no auto-reconnect
(codex outside-voice flagged that as session-burning).

sidepanel.css: primary-tabs bar + Terminal pane styling (full-height
xterm container, install card, ended state).

* test: terminal-agent + cookie module + sidebar default-tab regression

Three new test files:

terminal-agent.test.ts (16 tests): pty-session-cookie mint/validate/
revoke, Set-Cookie shape (HttpOnly + SameSite=Strict + Path=/, NO Secure
since 127.0.0.1 over HTTP), source-level guards that /pty-session and
/terminal/* are NOT in TUNNEL_PATHS, /health does NOT surface ptyToken
or gstack_pty, terminal-agent binds 127.0.0.1, /ws upgrade enforces
chrome-extension:// Origin AND gstack_pty cookie, lazy-spawn invariant
(spawnClaude is called from message handler, not upgrade), uncaughtException/
unhandledRejection handlers exist, SIGINT-then-SIGKILL cleanup.

terminal-agent-integration.test.ts (7 tests): spawns the agent as a real
subprocess in a tmp state dir. Verifies /internal/grant accepts/rejects
the loopback token, /ws gates (no Origin → 403, bad Origin → 403, no
cookie → 401), real WebSocket round-trip with /bin/bash via the
BROWSE_TERMINAL_BINARY override (write 'echo hello-pty-world\n', read it
back), and resize message acceptance.

sidebar-tabs.test.ts (13 tests): structural regression suite locking the
load-bearing invariants of the default-tab change — Terminal is .active,
Chat is not, xterm assets are loaded, debug-close path no longer hardcodes
tab-chat (uses activePrimaryPaneId), primary-tab click handler exists,
chat surface is not accidentally deleted, terminal JS does NOT auto-
reconnect on close, manifest declares ws:// + http:// localhost host
permissions, no unsafe-eval.

Plan called for Playwright + extension regression; the codebase doesn't
ship Playwright extension launcher infra, so we follow the existing
extension-test pattern (source-level structural assertions). Same
load-bearing intent — locks the invariants before they regress.

* docs: Terminal flow + threat model + v1.1 follow-ups

SIDEBAR_MESSAGE_FLOW.md: new "Terminal flow" section. Documents the WS
upgrade path (/pty-session cookie mint → /ws Origin + cookie gate →
lazy claude spawn), the dual-token model (AUTH_TOKEN for /pty-session,
gstack_pty cookie for /ws, INTERNAL_TOKEN for server↔agent loopback),
and the threat-model boundary — the Terminal tab bypasses the entire
prompt-injection security stack on purpose; user keystrokes are the
trust source. That trust assumption is load-bearing on three transport
guarantees: local-only listener, Origin gate, cookie auth. Drop any
one of those three and the tab becomes unsafe.

CLAUDE.md: extends the "Sidebar architecture" note to include
terminal-agent.ts in the read-this-first list. Adds a "Terminal tab is
its own process" note so a future contributor doesn't bolt PTY logic
onto sidebar-agent.ts.

TODOS.md: three new follow-ups under a new "Sidebar Terminal" section:
  - v1.1: PTY session survives sidebar reload (Issue 1C deferred).
  - v1.1+: audit /health AUTH_TOKEN distribution (codex finding #2 —
    a pre-existing soft leak that cc-pty-import sidesteps but doesn't
    fix).
  - v1.1+: apply terminal-agent's process.on exception handlers to
    sidebar-agent.ts (codex finding #4 — chat path has no fatal
    handlers).

* feat(extension): Terminal-only sidebar — auth fix, UX polish, chat rip

The chat queue path is gone. The Chrome side panel is now just an
interactive claude PTY in xterm.js. Activity / Refs / Inspector still
exist behind the `debug` toggle in the footer.

Three threads of change, all from dogfood iteration on top of
cc-pty-import:

1. fix(server): cross-port WS auth via Sec-WebSocket-Protocol
   - Browsers can't set Authorization on a WebSocket upgrade. We had
     been minting an HttpOnly gstack_pty cookie via /pty-session, but
     SameSite=Strict cookies don't survive the cross-port jump from
     server.ts:34567 to the agent's random port from a chrome-extension
     origin. The WS opened then immediately closed → "Session ended."
   - /pty-session now also returns ptySessionToken in the JSON body.
   - Extension calls `new WebSocket(url, [`gstack-pty.<token>`])`.
     Browser sends Sec-WebSocket-Protocol on the upgrade.
   - Agent reads the protocol header, validates against validTokens,
     and MUST echo the protocol back (Chromium closes the connection
     immediately if a server doesn't pick one of the offered protocols).
   - Cookie path is kept as a fallback for non-browser callers (curl,
     integration tests).
   - New integration test exercises the full protocol-auth round-trip
     via raw fetch+Upgrade so a future regression of this exact class
     fails in CI.

2. fix(extension): UX polish on the Terminal pane
   - Eager auto-connect when the sidebar opens — no "Press any key to
     start" friction every reload.
   - Always-visible ↻ Restart button in the terminal toolbar (not
     gated on the ENDED state) so the user can force a fresh claude
     mid-session.
   - MutationObserver on #tab-terminal's class attribute drives a
     fitAddon.fit() + term.refresh() when the pane becomes visible
     again — xterm doesn't auto-redraw after display:none → display:flex.

3. feat(extension): rip the chat tab + sidebar-agent.ts
   - Sidebar is Terminal-only. No more Terminal | Chat primary nav.
   - sidebar-agent.ts deleted. /sidebar-command, /sidebar-chat,
     /sidebar-agent/event, /sidebar-tabs* and friends all deleted.
   - The pickSidebarModel router (sonnet vs opus) is gone — the live
     PTY uses whatever model the user's `claude` CLI is configured with.
   - Quick-actions (🧹 Cleanup / 📸 Screenshot / 🍪 Cookies) survive
     in the Terminal toolbar. Cleanup now injects its prompt into the
     live PTY via window.gstackInjectToTerminal — no more
     /sidebar-command POST. The Inspector "Send to Code" action uses
     the same injection path.
   - clear-chat button removed from the footer.
   - sidepanel.js shed ~900 lines of chat polling, optimistic UI,
     stop-agent, etc.

Net diff: -3.4k lines across 16 files. CLAUDE.md, TODOS.md, and
docs/designs/SIDEBAR_MESSAGE_FLOW.md rewritten to match. The sidebar
regression test (browse/test/sidebar-tabs.test.ts) is rewritten as 27
structural assertions locking the new layout — Terminal sole pane,
no chat input, quick-actions in toolbar, eager-connect, MutationObserver
repaint, restart helper.

* feat: live tab awareness for the Terminal pane

claude in the PTY now has continuous tab-aware context. Three pieces:

1. Live state files. background.js listens to chrome.tabs.onActivated /
   onCreated / onRemoved / onUpdated (throttled to URL/title/status==
   complete so loading spinners don't spam) and pushes a snapshot. The
   sidepanel relays it as a custom event; sidepanel-terminal.js sends
   {type:"tabState"} text frames over the live PTY WebSocket.
   terminal-agent.ts writes:
     <stateDir>/tabs.json          all open tabs (id, url, title, active,
                                   pinned, audible, windowId)
     <stateDir>/active-tab.json    current active tab (skips chrome:// and
                                   chrome-extension:// internal pages)
   Atomic write via tmp + rename so claude never reads a half-written
   document. A fresh snapshot is pushed on WS open so the files exist by
   the time claude finishes booting.

2. New $B tab-each <command> [args...] meta-command. Fans out a single
   command across every open tab, returns
   {command, args, total, results: [{tabId, url, title, status, output}]}.
   Skips chrome:// pages; restores the originally active tab in a finally
   block (so a mid-batch error doesn't leave the user looking at a
   different tab); uses bringToFront: false so the OS window doesn't
   jump on every fanout. Scope-checks the inner command BEFORE the loop.

3. --append-system-prompt hint at spawn time. Claude is told about both
   the state files and the $B tab-each command up front, so it doesn't
   have to discover the surface by trial. Passed via the --append-system-
   prompt CLI flag, NOT as a leading PTY write — the hint stays out of
   the visible transcript.

Tests:
- browse/test/tab-each.test.ts (new) — registration + source-level
  invariants (scope check before loop, finally-restore, bringToFront:false,
  chrome:// skip) + behavior tests with a mock BrowserManager that verify
  iteration order, JSON shape, error handling, and active-tab restore.
- browse/test/terminal-agent.test.ts — three new assertions for
  tabState handler shape, atomic-write pattern, and the
  --append-system-prompt wiring at spawn.

Verified live: opened 5 tabs, ran $B tab-each url against the live
server, got per-tab JSON results back, original active tab restored
without OS focus stealing.

* chore: drop sidebar-agent test refs after chat rip

Five test files / describe blocks targeted the deleted chat path:
- browse/test/security-e2e-fullstack.test.ts (full-stack chat-pipeline E2E
  with mock claude — whole file gone)
- browse/test/security-review-fullstack.test.ts (review-flow E2E with real
  classifier — whole file gone)
- browse/test/security-review-sidepanel-e2e.test.ts (Playwright E2E for
  the security event banner that was ripped from sidepanel.html)
- browse/test/security-audit-r2.test.ts (5 describe blocks: agent queue
  permissions, isValidQueueEntry stateFile traversal, loadSession session-ID
  validation, switchChatTab DocumentFragment, pollChat reentrancy guard,
  /sidebar-tabs URL sanitization, sidebar-agent SIGTERM→SIGKILL escalation,
  AGENT_SRC top-level read converted to graceful fallback)
- browse/test/security-adversarial-fixes.test.ts (canary stream-chunk split
  detection on detectCanaryLeak; one tool-output test on sidebar-agent)
- test/skill-validation.test.ts (sidebar agent #584 describe block)

These all assumed sidebar-agent.ts existed and tested chat-queue plumbing,
chat-tab DOM round-trip, chat-polling reentrancy, or per-message classifier
canary detection. With the live PTY there is no chat queue, no chat tab,
no LLM stream to canary-scan, and no per-message subprocess. The Terminal
pane's invariants are covered by the new browse/test/sidebar-tabs.test.ts
(27 structural assertions), browse/test/terminal-agent.test.ts, and
browse/test/terminal-agent-integration.test.ts.

bun test → exit 0, 0 failures.

* chore: bump version and changelog (v1.14.0.0)

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

* fix(extension): xterm fills the full Terminal panel height

The Terminal pane only rendered into the top portion of the panel — most
of the panel below the prompt was an empty black gap. Three layered
issues, all about xterm.js measuring dimensions during a layout state
that wasn't ready yet:

1. order-of-operations in connect(): ensureXterm() ran BEFORE
   setState(LIVE), so term.open() measured els.mount while it was still
   display:none. xterm caches a 0-size viewport synchronously inside
   open() and never auto-recovers when the container goes visible.
   Flipped: setState(LIVE) → ensureXterm.

2. first fit() ran synchronously before the browser had applied the
   .active class transition. Wrapped in requestAnimationFrame so layout
   has settled before fit() reads clientHeight.

3. CSS flex-overflow trap: .terminal-mount has flex:1 inside the
   flex-column #tab-terminal, but .tab-content's `overflow-y: auto` and
   the lack of `min-height: 0` on .terminal-mount meant the item
   couldn't shrink below content size. flex:1 then refused to expand
   into available space and xterm rendered into whatever its initial
   2x2 measurement happened to be.

Fixes:
- extension/sidepanel-terminal.js: reorder + RAF fit
- extension/sidepanel.css: .terminal-mount gets `flex: 1 1 0` +
  `min-height: 0` + `position: relative`. #tab-terminal overrides
  .tab-content's `overflow-y: auto` to `overflow: hidden` (xterm has
  its own viewport scroll; the parent shouldn't compete) and explicitly
  re-declares `display: flex; flex-direction: column` for #tab-terminal.active.

bun test browse/test/sidebar-tabs.test.ts → 27/27 pass.
Manually verified: side panel opens → Terminal fills full panel height,
xterm scrollback works, debug-tab toggle still repaints correctly.

* fix(browse): Windows launcher extraEnv + headed-mode token (#822)

Community PR #822 by @pieterklue. Three fixes:
1. Windows launcher now merges extraEnv into spawned server env (was

2. Welcome page fallback serves inline HTML instead of about:blank
   redirect (avoids ERR_UNSAFE_REDIRECT on Windows)
3. /health returns auth token in headed mode even without Origin header

* feat: auto-track user-created tabs and handle tab close

browser-manager.ts changes:
- context.on('page') listener: automatically tracks tabs opened by the user
  (Cmd+T, right-click open in new tab, window.open). Previously only
  programmatic newTab() was tracked, so user tabs were invisible.
- page.on('close') handler in wirePageEvents: removes closed tabs from the
  pages map and switches activeTabId to the last remaining tab.
- syncActiveTabByUrl: match Chrome extension's active tab URL to the correct
  Playwright page for accurate tab identity.

* feat: per-tab agent isolation via BROWSE_TAB environment variable

Prevents parallel sidebar agents from interfering with each other's tab context.

Three-layer fix:
- sidebar-agent.ts: passes BROWSE_TAB=<tabId> env var to each claude process,
  per-tab processing set allows concurrent agents across tabs
- cli.ts: reads process.env.BROWSE_TAB and includes tabId in command request body
- server.ts: handleCommand() temporarily switches activeTabId when tabId is present,
  restores after command completes (safe: Bun event loop is single-threaded)

Also: per-tab agent state (TabAgentState map), per-tab message queuing,
per-tab chat buffers, verbose streaming narration, stop button endpoint.

* feat: sidebar per-tab chat context, tab bar sync, stop button, UX polish

Extension changes:
- sidepanel.js: per-tab chat history (tabChatHistories map), switchChatTab()
  swaps entire chat view, browserTabActivated handler for instant tab sync,
  stop button wired to /sidebar-agent/stop, pollTabs renders tab bar
- sidepanel.html: updated banner text ("Browser co-pilot"), stop button markup,
  input placeholder "Ask about this page..."
- sidepanel.css: tab bar styles, stop button styles, loading state fixes
- background.js: chrome.tabs.onActivated sends browserTabActivated to sidepanel
  with tab URL for instant tab switch detection

* test: per-tab isolation, BROWSE_TAB pinning, tab tracking, sidebar UX

sidebar-agent.test.ts (new tests):
- BROWSE_TAB env var passed to claude process
- CLI reads BROWSE_TAB and sends tabId in body
- handleCommand accepts tabId, saves/restores activeTabId
- Tab pinning only activates when tabId provided
- Per-tab agent state, queue, concurrency
- processingTabs set for parallel agents

sidebar-ux.test.ts (new tests):
- context.on('page') tracks user-created tabs
- page.on('close') removes tabs from pages map
- Tab isolation uses BROWSE_TAB not system prompt hack
- Per-tab chat context in sidepanel
- Tab bar rendering, stop button, banner text

* fix: resolve merge conflicts — keep security defenses + per-tab isolation

Merged main's security improvements (XML escaping, prompt injection defense,
allowed commands whitelist, --model opus, Write tool, stderr capture) with
our branch's per-tab isolation (BROWSE_TAB env var, processingTabs set,
no --resume). Updated test expectations for expanded system prompt.

* chore: bump version and changelog (v0.13.9.0)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: add inspector message types to background.js allowlist

Pre-existing bug found by Codex: ALLOWED_TYPES in background.js was missing
all inspector message types (startInspector, stopInspector, elementPicked,
pickerCancelled, applyStyle, toggleClass, injectCSS, resetAll, inspectResult).
Messages were silently rejected, making the inspector broken on ALL pages.

Also: separate executeScript and insertCSS into individual try blocks in
injectInspector(), store inspectorMode for routing, and add content.js
fallback when script injection fails (CSP, chrome:// pages).

* feat: basic element picker in content.js for CSP-restricted pages

When inspector.js can't be injected (CSP, chrome:// pages), content.js
provides a basic picker using getComputedStyle + CSSOM:
- startBasicPicker/stopBasicPicker message handlers
- captureBasicData() with ~30 key CSS properties, box model, matched rules
- Hover highlight with outline save/restore (never leaves artifacts)
- Click uses e.target directly (no re-querying by selector)
- Sends inspectResult with mode:'basic' for sidebar rendering
- Escape key cancels picker and restores outlines

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: cleanup + screenshot buttons in sidebar inspector toolbar

Two action buttons in the inspector toolbar:
- Cleanup (🧹): POSTs cleanup --all to server, shows spinner, chat
  notification on success, resets inspector state (element may be removed)
- Screenshot (📸): POSTs screenshot to server, shows spinner, chat
  notification with saved file path

Shared infrastructure:
- .inspector-action-btn CSS with loading spinner via ::after pseudo-element
- chat-notification type in addChatEntry() for system messages
- package.json version bump to 0.13.9.0

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: inspector allowlist, CSP fallback, cleanup/screenshot buttons

16 new tests in sidebar-ux.test.ts:
- Inspector message allowlist includes all inspector types
- content.js basic picker (startBasicPicker, captureBasicData, CSSOM,
  outline save/restore, inspectResult with mode basic, Escape cleanup)
- background.js CSP fallback (separate try blocks, inspectorMode, fallback)
- Cleanup button (POST /command, inspector reset after success)
- Screenshot button (POST /command, notification rendering)
- Chat notification type and CSS styles

* docs: update project documentation for v0.13.9.0

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: cleanup + screenshot buttons in chat toolbar (not just inspector)

Quick actions toolbar (🧹 Cleanup, 📸 Screenshot) now appears above the chat
input, always visible. Both inspector and chat buttons share runCleanup() and
runScreenshot() helper functions. Clicking either set shows loading state on
both simultaneously.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: chat toolbar buttons, shared helpers, quick-action-btn styles

Tests that chat toolbar exists (chat-cleanup-btn, chat-screenshot-btn,
quick-actions container), CSS styles (.quick-action-btn, .quick-action-btn.loading),
shared runCleanup/runScreenshot helper functions, and cleanup inspector reset.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: aggressive cleanup heuristics — overlays, scroll unlock, blur removal

Massively expanded CLEANUP_SELECTORS with patterns from uBlock Origin and
Readability.js research:
- ads: 30+ selectors (Google, Amazon, Outbrain, Taboola, Criteo, etc.)
- cookies: OneTrust, Cookiebot, TrustArc, Quantcast + generic patterns
- overlays (NEW): paywalls, newsletter popups, interstitials, push prompts,
  app download banners, survey modals
- social: follow prompts, share tools
- Cleanup now defaults to --all when no args (sidebar button fix)
- Uses !important on all display:none (overrides inline styles)
- Unlocks body/html scroll (overflow:hidden from modal lockout)
- Removes blur/filter effects (paywall content blur)
- Removes max-height truncation (article teaser truncation)
- Collapses empty ad placeholder whitespace (empty divs after ad removal)
- Skips gstack-ctrl indicator in sticky removal

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: disable action buttons when disconnected, no error spam

- setActionButtonsEnabled() toggles .disabled class on all cleanup/screenshot
  buttons (both chat toolbar and inspector toolbar)
- Called with false in updateConnection when server URL is null
- Called with true when connection established
- runCleanup/runScreenshot silently return when disconnected instead of
  showing 'Not connected' error notifications
- CSS .disabled style: pointer-events:none, opacity:0.3, cursor:not-allowed

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: cleanup heuristics, button disabled state, overlay selectors

17 new tests:
- cleanup defaults to --all on empty args
- CLEANUP_SELECTORS overlays category (paywall, newsletter, interstitial)
- Major ad networks in selectors (doubleclick, taboola, criteo, etc.)
- Major consent frameworks (OneTrust, Cookiebot, TrustArc, Quantcast)
- !important override for inline styles
- Scroll unlock (body overflow:hidden)
- Blur removal (paywall content blur)
- Article truncation removal (max-height)
- Empty placeholder collapse
- gstack-ctrl indicator skip in sticky cleanup
- setActionButtonsEnabled function
- Buttons disabled when disconnected
- No error spam from cleanup/screenshot when disconnected
- CSS disabled styles for action buttons

* feat: LLM-based page cleanup — agent analyzes page semantically

Instead of brittle CSS selectors, the cleanup button now sends a prompt to
the sidebar agent (which IS an LLM). The agent:
1. Runs deterministic $B cleanup --all as a quick first pass
2. Takes a snapshot to see what's left
3. Analyzes the page semantically to identify remaining clutter
4. Removes elements intelligently, preserving site branding

This means cleanup works correctly on any site without site-specific selectors.
The LLM understands that "Your Daily Puzzles" is clutter, "ADVERTISEMENT" is
junk, but the SF Chronicle masthead should stay.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: aggressive cleanup heuristics + preserve top nav bar

Deterministic cleanup improvements (used as first pass before LLM analysis):
- New 'clutter' category: audio players, podcast widgets, sidebar puzzles/games,
  recirculation widgets (taboola, outbrain, nativo), cross-promotion banners
- Text-content detection: removes "ADVERTISEMENT", "Article continues below",
  "Sponsored", "Paid content" labels and their parent wrappers
- Sticky fix: preserves the topmost full-width element near viewport top (site
  nav bar) instead of hiding all sticky/fixed elements. Sorts by vertical
  position, preserves the first one that spans >80% viewport width.

Tests: clutter category, ad label removal, nav bar preservation logic.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: LLM-based cleanup architecture, deterministic heuristics, sticky nav

22 new tests covering:
- Cleanup button uses /sidebar-command (agent) not /command (deterministic)
- Cleanup prompt includes deterministic first pass + agent snapshot analysis
- Cleanup prompt lists specific clutter categories for agent guidance
- Cleanup prompt preserves site identity (masthead, headline, body, byline)
- Cleanup prompt instructs scroll unlock and $B eval removal
- Loading state management (async agent, setTimeout)
- Deterministic clutter: audio/podcast, games/puzzles, recirculation
- Ad label text patterns (ADVERTISEMENT, Sponsored, Article continues)
- Ad label parent wrapper hiding for small containers
- Sticky nav preservation (sort by position, first full-width near top)

* feat: GStack Browser stealth + branding — anti-bot patches, custom UA, rebrand

- Add GSTACK_CHROMIUM_PATH env var for custom Chromium binary
- Add BROWSE_EXTENSIONS_DIR env var for extension path override
- Move auth token to /health endpoint (fixes read-only .app bundles)
- Anti-bot stealth: disable navigator.webdriver, fake plugins, languages
- Custom user agent: Chrome/<version> GStackBrowser (auto-detects version)
- Rebrand Chromium plist to "GStack Browser" at launch time
- Update security test to match new token-via-health approach

* feat: GStack Browser .app bundle — launcher script + build system

- scripts/app/gstack-browser: dual-mode launcher (dev + .app bundle)
- scripts/build-app.sh: compiles binary, bundles Chromium + extension, creates DMG
- Rebrands Chromium plist during build for "GStack Browser" in menu bar
- 389MB .app, 189MB compressed DMG, launches in ~5s

* docs: GStack Browser V0 master plan — AI-native development browser vision

5-phase roadmap from .app wrapper through Chromium fork, 9 capability
visions, competitive landscape, architecture diagrams, design system.

* fix: restore package.json and sync version to 0.14.3.0

* chore: bump version and changelog (v0.14.4.0)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* chore: gitignore top-level dist/ (GStack Browser build output)

* feat: GStack Browser icon — custom .icns replaces Chromium's Dock icon

- Generated 1024px icon: dark terminal window with amber prompt cursor
- Converted to .icns with all macOS sizes (16-1024px, 1x and 2x)
- build-app.sh copies icon into both the outer .app and bundled Chromium's
  Resources (Chromium's process owns the Dock icon, not the launcher)
- browser-manager.ts patches Chromium's icon at runtime for dev mode too
- Both the Dock and Cmd+Tab now show the GStack icon

* feat: rename /connect-chrome → /open-gstack-browser

- Rename skill directory + update frontmatter name and description
- Update SKILL.md.tmpl to reference GStack Browser branding/stealth
- Create connect-chrome symlink for backwards compatibility
- Setup script creates /connect-chrome alias in .claude/skills/
- Fix package.json version sync (0.14.5.0 → 0.14.6.0)

* feat: rename /connect-chrome → /open-gstack-browser across all references

Update README skill lists, docs/skills.md deep dive, extension sidepanel
banner copy button, and reconnect clipboard text.

* feat: left-align sidebar UI + extension-ready event for welcome page

- Left-align all sidebar text (chat welcome, loading, empty states,
  notifications, inspector empty, session placeholder)
- Dispatch 'gstack-extension-ready' CustomEvent from content.js so
  the welcome page can detect when the sidebar is active

* chore: add GStack Browser TODOs — CDP stealth patches + Chromium fork

P1: rebrowser-style postinstall patcher for Playwright 1.58.2 (suppress
Runtime.enable, addBinding context discovery, 6 files, ~200 lines).
P2: long-term Chromium fork for permanent stealth + native sidebar.

* chore: regenerate open-gstack-browser/SKILL.md from template

Fix timeline skill name (connect-chrome → open-gstack-browser) and
preamble formatting from merge with main's updated template.

* feat: welcome page served from browse server on headed launch

- Add /welcome endpoint to server.ts, serves welcome.html
- Navigate to /welcome after server starts (not during launchHeaded,
  which runs before the server is listening)
- welcome.html bundled in browse/src/ for portability

* feat: auto-open sidebar on every browser launch, not just first install

- Add top-level setTimeout in background.js that fires on every service
  worker startup (onInstalled only fires on install/update)
- Remove misaligned arrow from welcome page, replace with text fallback
  that hides when extension content script fires gstack-extension-ready

* fix: sidebar auto-open retry with backoff + welcome page tests

- Replace single-attempt sidePanel.open() with autoOpenSidePanel() that
  retries up to 5 times with 500ms-5000ms backoff
- Fire on both onInstalled AND every service worker startup
- Remove misaligned arrow from welcome page, replace with text fallback
- Add 12 tests: welcome page structure, /welcome endpoint, headed launch
  navigation timing, sidebar auto-open retry logic, extension-ready event

* feat: reload button in sidebar footer

Adds a "reload" button next to "debug" and "clear" in the sidebar
footer. Calls location.reload() to fully refresh the side panel,
re-run connection logic, and clear stale state.

* feat: right-pointing arrow hint for sidebar on welcome page

Replace invisible text fallback with visible amber bubble + animated
right arrow (→) pointing toward where the sidebar opens. Always correct
regardless of window size (unlike the old up arrow at toolbar chrome).

* fix: sidebar auth race — pass token in getPort response

The sidebar called tryConnect() → getPort → got {port, connected} but
NO token. All subsequent requests (SSE, chat poll) failed with 401.
The token only arrived later via the health broadcast, but by then
the SSE connection was already broken.

Fix: include authToken in the getPort response so the sidebar has
the token from its very first connection attempt.

* feat: sidebar debug visibility + auth race tests

- Show attempt count in loading screen ("Connecting... attempt 3")
- After 5 failed attempts, show debug details (port, connected, token)
  so stuck users can see exactly what's failing
- Add 4 tests: getPort includes token, tryConnect uses token,
  dead state exists with MAX_RECONNECT_ATTEMPTS, reconnectAttempts visible

* fix: startup health check retries every 1s instead of 10s

Root cause: extension service worker starts before Bun.serve() is
listening. First checkHealth() fails, next attempt is 10 seconds
later. User stares at "Connecting..." for 10 seconds.

Fix: retry every 1s for up to 15 attempts on startup, then switch
to 10s polling once connected (or after 15s gives up). Sidebar
should connect within 1-2 seconds of server becoming available.

3 new tests verify the fast-retry → slow-poll transition.

* feat: detailed step-by-step status in sidebar loading screen

Replace useless "Connecting..." with real-time debug info:
- "Looking for browse server... (attempt N)"
- Shows port, server responding status, token status
- Shows chrome.runtime errors if extension messaging fails
- Tells user to run /open-gstack-browser if server not found

* fix: sidebar connects directly to /health instead of waiting for background

Root cause: sidepanel asked background "are you connected?" but background's
health check hadn't succeeded yet (1-10s gap). Sidepanel waited forever.

Fix: when background says not connected, sidepanel hits /health directly
with fetch(). Gets the token from the response. Bypasses background
entirely for initial connection. Shows step-by-step debug info:
"Checking server directly... port: 34567 / Trying GET /health..."

* fix: suppress fake "session ended" and timeout errors in sidebar

Two issues making the sidebar look broken when it's actually working:
1. "Timed out after 300s" error displayed after agent_done — this is a
   cleanup timer, not a real error. Now suppressed when no active session.
2. "(session ended)" text appended on every idle poll — removed entirely.
   The thinking spinner is cleaned up silently instead.

* fix: sidebar agent passes BROWSE_PORT to child claude

Ensures the child claude process connects to the existing headed
browse server (port 34567) instead of spawning a new headless one.
Without this, sidebar chat commands run in an invisible browser.

* feat: BROWSE_NO_AUTOSTART prevents sidebar from spawning headless browser

When set, the browse CLI refuses to start a new server and exits with
a clear error: "Server not available, run /open-gstack-browser to restart."
The sidebar agent sets this so users never get an invisible headless
browser when the headed one is closed.

* test: BROWSE_NO_AUTOSTART guard in CLI + sidebar-agent env vars

5 tests: CLI checks env var before starting server, shows actionable
error, sidebar-agent sets the flag + BROWSE_PORT, guard runs before
lock acquisition to prevent stale lock files.

* fix: stale auth token causes Unauthorized + invisible error text

background.js checkHealth() never refreshed authToken from /health responses,
so when the browse server restarted with a new token, all sidebar-command
requests got 401 Unauthorized forever.

Also: error placeholder text was #3f3f46 on #0C0C0C (nearly invisible).
Now shows in red to match the error border.

* fix: replace 40+ silent catch blocks with debug logging

Every empty catch {} in sidepanel.js, sidebar-agent.ts now logs with
[gstack sidebar] or [sidebar-agent] prefix. Chat poll 401s, stop agent,
tab poll, clear chat, SSE parse, refs fetch, stream JSON parse, queue
read/parse, process kill — all now visible in console.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: noisy debug logging + auto model routing in browse server

Server-side silent catch blocks (22 instances) now log with [browse] prefix:
chat persistence, session save/load, agent kill, tab pin/restore, welcome
page, buffer flush, worktree cleanup, lock files, SSE streams.

Also adds pickSidebarModel() — routes sidebar messages to sonnet for
navigation/interaction (click, goto, fill, screenshot) and opus for
analysis/comprehension (summarize, describe, find bugs). Sonnet is
~4x faster for action commands with zero quality difference.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: update sidebar tests for model router + longer stopAgent slice

- stopAgent slice 800→1000 to accommodate added error logging lines
- Replace hardcoded opus assertion with model router assertions

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: sidebar arrow hint stays visible until sidebar actually opens

Previously the welcome page arrow hid immediately when the extension's
content script loaded — but extension loaded ≠ sidebar open. Now the
signal flow is: sidepanel connects → tells background.js → relays to
content script → dispatches gstack-extension-ready → arrow hides.

Adds welcome-page.test.ts: 14 tests verifying arrow, branding, feature
cards, dark theme, and auto-hide behavior via real HTTP server.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: arrow hide signal chain (4-step) + stale session-ended assertion

8 new tests verify the sidebarOpened → background → content → welcome
signal chain. Updates stale "(session ended)" test that checked for
text removed in a prior commit.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: preserve optimistic UI during tab switch on first message

When the user sends a message and the server assigns it to a new tab
(because Chrome's active tab changed), switchChatTab() was blowing away
the optimistic user bubble and thinking dots with a welcome screen.
Now preserves the current DOM if we're mid-send with a thinking indicator.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: sidebar message flow architecture doc + CLAUDE.md pointer

SIDEBAR_MESSAGE_FLOW.md documents the full init timeline, message flow
(user types → claude responds), auth token chain, arrow hint signal
chain, model routing, tab concurrency, and known failure modes.

CLAUDE.md now tells you to read it before touching sidebar files.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: sidebar chat resets idle timer + shutdown kills sidebar-agent

Two fixes for the "browser died while chatting" problem:

1. /sidebar-command now calls resetIdleTimer(). Previously only CLI
   commands reset it, so the server would shut down after 30 min even
   while the user was actively chatting in the sidebar.

2. shutdown() now pkills the sidebar-agent daemon. Previously the agent
   survived server shutdown, kept polling a dead server, and spawned
   confused claude processes that auto-started headless browsers.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: disable idle timeout in headed mode — browser lives until closed

The 30-minute idle timeout only applies to headless mode now. In headed
mode the user is looking at the Chrome window, so auto-shutdown is wrong.
The browser stays alive until explicit disconnect or window close.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: cookies button in sidebar footer opens cookie picker

One-click cookie import from the sidebar. Navigates the headed browser
to /cookie-picker where you can select which domains to import from
your real Chrome profile.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: update project documentation for GStack Browser improvements

README.md: updated Real browser mode and sidebar agent sections with
model routing, cookie import button, no idle timeout in headed mode.
Updated skill table entries for /browse and /open-gstack-browser.

docs/skills.md: updated /open-gstack-browser deep dive with model
routing and cookie import details.

GSTACK_BROWSER_V0.md: added 6 new SHIPPED items to implementation
status table (model routing, debug logging, idle timeout, cookie
button, arrow hint, architecture doc).

TODOS.md: marked "Sidebar agent Write tool + error visibility" as
SHIPPED. Added new P2 TODO for direct API calls to eliminate
claude -p startup tax.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add Claude Code terminal example to welcome page TRY IT NOW

Fifth example shows the parent agent workflow: navigate, extract CSS,
write to file. The other four are all sidebar-only. This one shows
co-presence — the Claude Code session that launched the browser can
also control it directly.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: hide internal tool-result file reads from sidebar activity

Claude reads its own ~/.claude/projects/.../tool-results/ files as
internal plumbing. These showed up as long unreadable paths in the
sidebar. Now: describeToolCall returns empty for tool-result reads,
and the sidebar skips rendering tool_use entries with no description.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: collapse tool calls into "See reasoning" disclosure on completion

While the agent is working, tool calls stream live so you can watch
progress. When the agent finishes, all tool calls collapse into a
"See reasoning (N steps)" disclosure. Click to expand and see what
the agent did. The final text answer stays visible.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: 17 new tests for recent sidebar fixes

Covers: tool-result file filtering, empty tool_use skip, reasoning
disclosure collapse, idle timeout headed mode bypass, sidebar-command
idle reset, shutdown sidebar-agent kill, cookie button, and model
routing analysis-before-action priority.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: move cookies button to quick actions toolbar

Cookies now sits next to Cleanup and Screenshot as a primary action
button (🍪 Cookies) instead of buried in the footer. Same behavior,
more discoverable.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add instructional text to cookie picker page

"Select the domains of cookies you want to import to GStack Browser.
You'll be able to browse those sites with the same login as your
other browser."

Also fixes stale test that expected hardcoded '--model', 'opus'.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: 6-card welcome page with cookie import + dual-agent cards

3x2 grid layout (was 2x2). New cards: "Import your cookies" (click
🍪 Cookies to import login sessions from Chrome/Arc/Brave) and
"Or use your main agent" (your Claude Code terminal also controls
this browser). Responsive: 3 cols > 2 cols > 1 col.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: move sidebar arrow hint to top-right instead of vertically centered

The arrow was centered vertically which put it behind the feature cards.
Now positioned at top: 80px where there's open space and it's more visible.

feat: sidebar CSS inspector + per-tab agents (v0.13.9.0) (#650)
* feat: CDP inspector module — persistent sessions, CSS cascade, style modification

New browse/src/cdp-inspector.ts with full CDP inspection engine:
- inspectElement() via CSS.getMatchedStylesForNode + DOM.getBoxModel
- modifyStyle() via CSS.setStyleTexts with headless page.evaluate fallback
- Persistent CDP session lifecycle (create, reuse, detach on nav, re-create)
- Specificity sorting, overridden property detection, UA rule filtering
- Modification history with undo support
- formatInspectorResult() for CLI output

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: browse server inspector endpoints + inspect/style/cleanup/prettyscreenshot CLI

Server endpoints: POST /inspector/pick, GET /inspector, POST /inspector/apply,
POST /inspector/reset, GET /inspector/history, GET /inspector/events (SSE).
CLI commands: inspect (CDP cascade), style (live CSS mod), cleanup (page clutter
removal), prettyscreenshot (clean screenshot pipeline).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: sidebar CSS inspector — element picker, box model, rule cascade, quick edit

Extension changes for the visual CSS inspector:
- inspector.js: element picker with hover highlight, CSS selector generation,
  basic mode fallback (getComputedStyle + CSSOM), page alteration handlers
- inspector.css: picker overlay styles (blue highlight + tooltip)
- background.js: inspector message routing (picker <-> server <-> sidepanel)
- sidepanel: Inspector tab with box model viz (gstack palette), matched rules
  with specificity badges, computed styles, click-to-edit quick edit,
  Send to Agent/Code button, empty/loading/error states

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: auto-track user-created tabs and handle tab close

browser-manager.ts changes:
- context.on('page') listener: automatically tracks tabs opened by the user
  (Cmd+T, right-click open in new tab, window.open). Previously only
  programmatic newTab() was tracked, so user tabs were invisible.
- page.on('close') handler in wirePageEvents: removes closed tabs from the
  pages map and switches activeTabId to the last remaining tab.
- syncActiveTabByUrl: match Chrome extension's active tab URL to the correct
  Playwright page for accurate tab identity.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: per-tab agent isolation via BROWSE_TAB environment variable

Prevents parallel sidebar agents from interfering with each other's tab context.

Three-layer fix:
- sidebar-agent.ts: passes BROWSE_TAB=<tabId> env var to each claude process,
  per-tab processing set allows concurrent agents across tabs
- cli.ts: reads process.env.BROWSE_TAB and includes tabId in command request body
- server.ts: handleCommand() temporarily switches activeTabId when tabId is present,
  restores after command completes (safe: Bun event loop is single-threaded)

Also: per-tab agent state (TabAgentState map), per-tab message queuing,
per-tab chat buffers, verbose streaming narration, stop button endpoint.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: sidebar per-tab chat context, tab bar sync, stop button, UX polish

Extension changes:
- sidepanel.js: per-tab chat history (tabChatHistories map), switchChatTab()
  swaps entire chat view, browserTabActivated handler for instant tab sync,
  stop button wired to /sidebar-agent/stop, pollTabs renders tab bar
- sidepanel.html: updated banner text ("Browser co-pilot"), stop button markup,
  input placeholder "Ask about this page..."
- sidepanel.css: tab bar styles, stop button styles, loading state fixes
- background.js: chrome.tabs.onActivated sends browserTabActivated to sidepanel
  with tab URL for instant tab switch detection

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: per-tab isolation, BROWSE_TAB pinning, tab tracking, sidebar UX

sidebar-agent.test.ts (new tests):
- BROWSE_TAB env var passed to claude process
- CLI reads BROWSE_TAB and sends tabId in body
- handleCommand accepts tabId, saves/restores activeTabId
- Tab pinning only activates when tabId provided
- Per-tab agent state, queue, concurrency
- processingTabs set for parallel agents

sidebar-ux.test.ts (new tests):
- context.on('page') tracks user-created tabs
- page.on('close') removes tabs from pages map
- Tab isolation uses BROWSE_TAB not system prompt hack
- Per-tab chat context in sidepanel
- Tab bar rendering, stop button, banner text

* fix: resolve merge conflicts — keep security defenses + per-tab isolation

Merged main's security improvements (XML escaping, prompt injection defense,
allowed commands whitelist, --model opus, Write tool, stderr capture) with
our branch's per-tab isolation (BROWSE_TAB env var, processingTabs set,
no --resume). Updated test expectations for expanded system prompt.

* chore: bump version and changelog (v0.13.9.0)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: add inspector message types to background.js allowlist

Pre-existing bug found by Codex: ALLOWED_TYPES in background.js was missing
all inspector message types (startInspector, stopInspector, elementPicked,
pickerCancelled, applyStyle, toggleClass, injectCSS, resetAll, inspectResult).
Messages were silently rejected, making the inspector broken on ALL pages.

Also: separate executeScript and insertCSS into individual try blocks in
injectInspector(), store inspectorMode for routing, and add content.js
fallback when script injection fails (CSP, chrome:// pages).

* feat: basic element picker in content.js for CSP-restricted pages

When inspector.js can't be injected (CSP, chrome:// pages), content.js
provides a basic picker using getComputedStyle + CSSOM:
- startBasicPicker/stopBasicPicker message handlers
- captureBasicData() with ~30 key CSS properties, box model, matched rules
- Hover highlight with outline save/restore (never leaves artifacts)
- Click uses e.target directly (no re-querying by selector)
- Sends inspectResult with mode:'basic' for sidebar rendering
- Escape key cancels picker and restores outlines

* feat: cleanup + screenshot buttons in sidebar inspector toolbar

Two action buttons in the inspector toolbar:
- Cleanup (🧹): POSTs cleanup --all to server, shows spinner, chat
  notification on success, resets inspector state (element may be removed)
- Screenshot (📸): POSTs screenshot to server, shows spinner, chat
  notification with saved file path

Shared infrastructure:
- .inspector-action-btn CSS with loading spinner via ::after pseudo-element
- chat-notification type in addChatEntry() for system messages
- package.json version bump to 0.13.9.0

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: inspector allowlist, CSP fallback, cleanup/screenshot buttons

16 new tests in sidebar-ux.test.ts:
- Inspector message allowlist includes all inspector types
- content.js basic picker (startBasicPicker, captureBasicData, CSSOM,
  outline save/restore, inspectResult with mode basic, Escape cleanup)
- background.js CSP fallback (separate try blocks, inspectorMode, fallback)
- Cleanup button (POST /command, inspector reset after success)
- Screenshot button (POST /command, notification rendering)
- Chat notification type and CSS styles

* docs: update project documentation for v0.13.9.0

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: cleanup + screenshot buttons in chat toolbar (not just inspector)

Quick actions toolbar (🧹 Cleanup, 📸 Screenshot) now appears above the chat
input, always visible. Both inspector and chat buttons share runCleanup() and
runScreenshot() helper functions. Clicking either set shows loading state on
both simultaneously.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: chat toolbar buttons, shared helpers, quick-action-btn styles

Tests that chat toolbar exists (chat-cleanup-btn, chat-screenshot-btn,
quick-actions container), CSS styles (.quick-action-btn, .quick-action-btn.loading),
shared runCleanup/runScreenshot helper functions, and cleanup inspector reset.

* feat: aggressive cleanup heuristics — overlays, scroll unlock, blur removal

Massively expanded CLEANUP_SELECTORS with patterns from uBlock Origin and
Readability.js research:
- ads: 30+ selectors (Google, Amazon, Outbrain, Taboola, Criteo, etc.)
- cookies: OneTrust, Cookiebot, TrustArc, Quantcast + generic patterns
- overlays (NEW): paywalls, newsletter popups, interstitials, push prompts,
  app download banners, survey modals
- social: follow prompts, share tools
- Cleanup now defaults to --all when no args (sidebar button fix)
- Uses !important on all display:none (overrides inline styles)
- Unlocks body/html scroll (overflow:hidden from modal lockout)
- Removes blur/filter effects (paywall content blur)
- Removes max-height truncation (article teaser truncation)
- Collapses empty ad placeholder whitespace (empty divs after ad removal)
- Skips gstack-ctrl indicator in sticky removal

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: disable action buttons when disconnected, no error spam

- setActionButtonsEnabled() toggles .disabled class on all cleanup/screenshot
  buttons (both chat toolbar and inspector toolbar)
- Called with false in updateConnection when server URL is null
- Called with true when connection established
- runCleanup/runScreenshot silently return when disconnected instead of
  showing 'Not connected' error notifications
- CSS .disabled style: pointer-events:none, opacity:0.3, cursor:not-allowed

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: cleanup heuristics, button disabled state, overlay selectors

17 new tests:
- cleanup defaults to --all on empty args
- CLEANUP_SELECTORS overlays category (paywall, newsletter, interstitial)
- Major ad networks in selectors (doubleclick, taboola, criteo, etc.)
- Major consent frameworks (OneTrust, Cookiebot, TrustArc, Quantcast)
- !important override for inline styles
- Scroll unlock (body overflow:hidden)
- Blur removal (paywall content blur)
- Article truncation removal (max-height)
- Empty placeholder collapse
- gstack-ctrl indicator skip in sticky cleanup
- setActionButtonsEnabled function
- Buttons disabled when disconnected
- No error spam from cleanup/screenshot when disconnected
- CSS disabled styles for action buttons

* feat: LLM-based page cleanup — agent analyzes page semantically

Instead of brittle CSS selectors, the cleanup button now sends a prompt to
the sidebar agent (which IS an LLM). The agent:
1. Runs deterministic $B cleanup --all as a quick first pass
2. Takes a snapshot to see what's left
3. Analyzes the page semantically to identify remaining clutter
4. Removes elements intelligently, preserving site branding

This means cleanup works correctly on any site without site-specific selectors.
The LLM understands that "Your Daily Puzzles" is clutter, "ADVERTISEMENT" is
junk, but the SF Chronicle masthead should stay.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: aggressive cleanup heuristics + preserve top nav bar

Deterministic cleanup improvements (used as first pass before LLM analysis):
- New 'clutter' category: audio players, podcast widgets, sidebar puzzles/games,
  recirculation widgets (taboola, outbrain, nativo), cross-promotion banners
- Text-content detection: removes "ADVERTISEMENT", "Article continues below",
  "Sponsored", "Paid content" labels and their parent wrappers
- Sticky fix: preserves the topmost full-width element near viewport top (site
  nav bar) instead of hiding all sticky/fixed elements. Sorts by vertical
  position, preserves the first one that spans >80% viewport width.

Tests: clutter category, ad label removal, nav bar preservation logic.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: LLM-based cleanup architecture, deterministic heuristics, sticky nav

22 new tests covering:
- Cleanup button uses /sidebar-command (agent) not /command (deterministic)
- Cleanup prompt includes deterministic first pass + agent snapshot analysis
- Cleanup prompt lists specific clutter categories for agent guidance
- Cleanup prompt preserves site identity (masthead, headline, body, byline)
- Cleanup prompt instructs scroll unlock and $B eval removal
- Loading state management (async agent, setTimeout)
- Deterministic clutter: audio/podcast, games/puzzles, recirculation
- Ad label text patterns (ADVERTISEMENT, Sponsored, Article continues)
- Ad label parent wrapper hiding for small containers
- Sticky nav preservation (sort by position, first full-width near top)

* fix: prevent repeat chat message rendering on reconnect/replay

Root cause: server persists chat to disk (chat.jsonl) and replays on restart.
Client had no dedup, so every reconnect re-rendered the entire history.
Messages from an old HN session would repeat endlessly on the SF Chronicle tab.

Fix: renderedEntryIds Set tracks which entry IDs have been rendered. addChatEntry
skips entries already in the set. Entries without an id (local notifications)
bypass the check. Clear chat resets the set.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: agent stops when done, no focus stealing, opus for prompt injection safety

Three fixes for sidebar agent UX:
- System prompt: "Be CONCISE. STOP as soon as the task is done. Do NOT keep
  exploring or doing bonus work." Prevents agent from endlessly taking
  screenshots and highlighting elements after answering the question.
- switchTab(id, opts): new bringToFront option. Internal tab pinning
  (BROWSE_TAB) uses bringToFront: false so agent commands never steal
  window focus from the user's active app.
- Keep opus model (not sonnet) for prompt injection resistance on untrusted
  web pages. Remove Write from allowedTools (agent only needs Bash for $B).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: agent conciseness, focus stealing, opus model, switchTab opts

Tests for the three UX fixes:
- System prompt contains STOP/CONCISE/Do NOT keep exploring
- sidebar agent uses opus (not sonnet) for prompt injection resistance
- switchTab has bringToFront option, defaults to true (opt-out)
- handleCommand tab pinning uses bringToFront: false (no focus steal)
- Updated stale tests: switchTab signature, allowedTools excludes Write,
  narration -> conciseness, tab pinning restore calls

* test: sidebar CSS interaction E2E — HN comment highlight round-trip

New E2E test (periodic tier, ~$2/run) that exercises the full sidebar
agent pipeline with CSS interaction:
1. Agent navigates to Hacker News
2. Clicks into the top story's comments
3. Reads comments and identifies the most insightful one
4. Highlights it with a 4px solid orange outline via style injection

Tests: navigation, snapshot, text reading, LLM judgment, CSS modification.
Requires real browser + real Claude (ANTHROPIC_API_KEY).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: sidebar CSS E2E test — correct idle timeout (ms not s), pipe stdio

Root cause of test failure: BROWSE_IDLE_TIMEOUT is in milliseconds, not
seconds. '600' = 0.6 seconds, server died immediately after health check.
Fixed to '600000' (10 minutes).

Also: use 'pipe' stdio instead of file descriptors (closing fds kills child
on macOS/bun), catch ConnectionRefused on poll retry, 4 min poll timeout
for the multi-step opus task.

Test passes: agent navigates to HN, reads comments, identifies most
insightful one, highlights it with orange CSS, stops. 114s, $0.00.

fix: security audit round 2 (v0.13.4.0) (#640)
* fix: chrome-cdp localhost-only binding

Restrict Chrome CDP to localhost by adding --remote-debugging-address=127.0.0.1
and --remote-allow-origins to prevent network-accessible debugging sessions.

Clears 1 Socket anomaly (Chrome CDP session exposure).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: extension sender validation + message type allowlist

Add sender.id check and ALLOWED_TYPES allowlist to the Chrome extension's
message handler. Defense-in-depth against message spoofing from external
extensions or future externally_connectable changes.

Clears 2 Socket anomalies (extension permissions).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: checksum-verified bun install

Replace unverified curl|bash bun installation with checksum-verified
download-then-execute pattern. The install script is downloaded, sha256
verified against a known hash, then executed. Preserves the Bun-native
install path without adding a Node/npm dependency.

Clears Snyk W012 + 3 Socket anomalies.

* fix: content trust boundary markers in browse output

Wrap page-content commands (text, html, links, forms, accessibility,
console, dialog, snapshot) with --- BEGIN/END UNTRUSTED EXTERNAL CONTENT ---
markers. Covers direct commands (server.ts), chain sub-commands, and
snapshot output (meta-commands.ts).

Adds PAGE_CONTENT_COMMANDS set and wrapUntrustedContent() helper in
commands.ts (single source of truth, DRY). Expands the SKILL.md trust
warning with explicit processing rules for agents.

Clears Snyk W011 (third-party content exposure).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: harden trust boundary markers against escape attacks

- Sanitize URLs in markers (remove newlines, cap at 200 chars) to prevent
  marker injection via history.pushState
- Escape marker strings in content (zero-width space) so malicious pages
  can't forge the END marker to break out of the untrusted block
- Wrap resume command snapshot with trust boundary markers
- Wrap diff command output with trust boundary markers
- Wrap watch stop last snapshot with trust boundary markers

Found by cross-model adversarial review (Claude + Codex).

* chore: bump version and changelog (v0.13.4.0)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* chore: gitignore .factory/ and remove from tracking

Factory Droid support was removed in this branch. The .factory/ directory
was re-added by merging main (which had v0.13.5.0 Factory support).
Gitignore it so it stays out.

fix: security audit remediation — 12 fixes, 20 tests (v0.13.1.0) (#595)
* fix: remove auth token from /health, secure extension bootstrap (CRITICAL-02 + HIGH-03)

- Remove token from /health response (was leaked to any localhost process)
- Write .auth.json to extension dir for Manifest V3 bootstrap
- sidebar-agent reads token from state file via BROWSE_STATE_FILE env var
- Remove getToken handler from extension (token via health broadcast)
- Extension loads token before first health poll to prevent race condition

* fix: require auth on cookie-picker data routes (CRITICAL-01)

- Add Bearer token auth gate on all /cookie-picker/* data/action routes
- GET /cookie-picker HTML page stays unauthenticated (UI shell)
- Token embedded in served HTML for picker's fetch calls
- CORS preflight now allows Authorization header

* fix: add state file TTL and plaintext cookie warning (HIGH-02)

- Add savedAt timestamp to state save output
- Warn on load if state file older than 7 days
- Auto-delete stale state files (>7 days) on server startup
- Warning about plaintext cookie storage in save message

* fix: innerHTML XSS in extension content script and sidepanel (MEDIUM-01)

- content.js: replace innerHTML with createElement/textContent for ref panel
- sidepanel.js: escape entry.command with escapeHtml() in activity feed
- Both found by security audit + Codex adversarial red team

* fix: symlink bypass in validateReadPath (MEDIUM-02)

- Always resolve to absolute path first (fixes relative path bypass)
- Use realpathSync to follow symlinks before boundary check
- Throw on non-ENOENT realpathSync failures (explicit over silent)
- Resolve SAFE_DIRECTORIES through realpathSync (macOS /tmp → /private/tmp)
- Resolve directory part for non-existent files (ENOENT with symlinked parent)

* fix: freeze hook symlink bypass and prefix collision (MEDIUM-03)

- Add POSIX-portable path resolution (cd + pwd -P, works on macOS)
- Fix prefix collision: /project-evil no longer matches /project freeze dir
- Use trailing slash in boundary check to require directory boundary

* fix: shell script injection in gstack-config and telemetry (MEDIUM-04)

- gstack-config: validate keys (alphanumeric+underscore only)
- gstack-config: use grep -F (fixed string) instead of -E (regex)
- gstack-config: escape sed special chars in values, drop newlines
- gstack-telemetry-log: sanitize REPO_SLUG and BRANCH via json_safe()

* test: 20 security tests for audit remediation

- server-auth: verify token removed from /health, auth on /refs, /activity/*
- cookie-picker: auth required on data routes, HTML page unauthenticated
- path-validation: symlink bypass blocked, realpathSync failure throws
- gstack-config: regex key rejected, sed special chars preserved
- state-ttl: savedAt timestamp, 7-day TTL warning
- telemetry: branch/repo with quotes don't corrupt JSON
- adversarial: sidepanel escapes entry.command, freeze prefix collision

* chore: bump version and changelog (v0.13.1.0)

fix: sidebar agent uses real tab URL instead of stale Playwright URL (v0.12.6.0) (#544)
* fix: sidebar agent uses extension's activeTabUrl instead of stale Playwright URL

When the user navigates manually in headed Chrome, Playwright's page.url()
stays on the old page. The sidebar agent was using this stale URL in its
system prompt, causing it to navigate to the wrong page (e.g., Hacker News
instead of the user's current page).

The Chrome extension now captures the active tab URL via chrome.tabs.query()
and sends it as activeTabUrl in the /sidebar-command POST body. The server
prefers this over Playwright's URL. The URL is sanitized (http/https only,
control chars stripped, 2048 char limit) to prevent prompt injection.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: connect-chrome pre-flight cleanup + improved onboarding docs

Adds Step 0 pre-flight cleanup that kills stale browse servers and cleans
Chromium profile locks before connecting. Improves the onboarding flow with
clearer instructions for finding the extension, opening the Side Panel, and
troubleshooting connection issues. Fixes Mode check from cdp to headed.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: sidebar agent test suite (layers 1-2)

Layer 1 (unit): 18 tests for URL sanitization in sidebar-utils.ts — http/https
pass, chrome:// rejected, javascript: rejected, control chars stripped, truncation.

Layer 2 (integration): 13 tests for server HTTP endpoints — auth, sidebar-command
queue writes, activeTabUrl override/fallback, event relay to chat buffer, message
queuing, queue overflow (429), chat clear, agent kill.

Source changes for testability:
- Extract sanitizeExtensionUrl() to browse/src/sidebar-utils.ts
- Add BROWSE_HEADLESS_SKIP env var to skip browser launch in HTTP-only tests
- Add SIDEBAR_QUEUE_PATH env var to both server.ts and sidebar-agent.ts
- Add SIDEBAR_AGENT_TIMEOUT env var to sidebar-agent.ts
- Sync package.json version to match VERSION (0.12.2.0)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: sidebar agent round-trip tests with mock claude (layer 3)

Starts server + sidebar-agent together with a mock claude binary (shell script
outputting canned stream-json). Verifies the full queue-based message flow:

- Full round-trip: POST /sidebar-command → queue → agent → mock claude → events → chat
- Claude crash recovery: mock exits 1, agent_error appears, status returns to idle
- Sequential queue drain: two rapid messages both process in order

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: sidebar agent E2E tests with real Claude (layer 4)

Two E2E tests that exercise the full sidebar agent flow with real Claude:

- sidebar-navigate: POST /sidebar-command asking Claude to describe a fixture
  page, verify it responds with page content through the chat buffer
- sidebar-url-accuracy: POST with activeTabUrl differing from Playwright URL,
  verify the queue prompt uses the extension URL (the core bug fix)

Both registered as periodic tier (~$0.80 total, non-deterministic).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: sidebar E2E tests — sequential execution + eval collector fix

Both tests now pass:
- sidebar-url-accuracy: deterministic queue file check (no Claude needed)
- sidebar-navigate: real Claude responds through sidebar agent queue

Fixed: testIfSelected (sequential, not concurrent) to avoid queue file
conflicts. Added cost_usd field for eval collector compatibility.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: kill stale sidebar-agent processes before starting new one

Each /connect-chrome starts a new sidebar-agent subprocess with unref()
but never kills the previous one. Old agents accumulate as zombies with
stale auth tokens. When they pick up queue entries, their event relay
fails (401), so the server never receives agent_done and marks the agent
as "hung". The user sees the sidebar freeze.

Fix: pkill any existing sidebar-agent.ts processes before spawning.

feat: headed mode + sidebar agent + Chrome extension (v0.12.0) (#517)
* feat: CDP connect — control real Chrome/Comet via Playwright

Add `connectCDP()` to BrowserManager: connects to a running browser via
Chrome DevTools Protocol. All existing browse commands work unchanged
through Playwright's abstraction layer.

- chrome-launcher.ts: browser discovery, CDP probe, auto-relaunch with rollback
- browser-manager.ts: connectCDP(), mode guards (close/closeTab/recreateContext/handoff),
  auto-reconnect on browser restart, getRefMap() for extension API
- server.ts: CDP branch in start(), /health gains mode field, /refs endpoint,
  idle timer only resets on /command (not passive endpoints)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: browse connect/disconnect/focus CLI commands

- connect: pre-server command that discovers browser, starts server in CDP mode
- disconnect: drops CDP connection, restarts in headless mode
- focus: brings browser window to foreground via osascript (macOS)
- status: now shows Mode: cdp | launched | headed
- startServer() accepts extra env vars for CDP URL/port passthrough

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: CDP-aware skill templates — skip cookie import in real browser mode

Skills now check `$B status` for CDP mode and skip:
- /qa: cookie import prompt, user-agent override, headless workarounds
- /design-review: cookie import for authenticated pages
- /setup-browser-cookies: returns "not needed" in CDP mode

Regenerated SKILL.md files from updated templates.

* feat: activity streaming — SSE endpoint for Chrome extension Side Panel

Real-time browse command feed via Server-Sent Events:
- activity.ts: ActivityEntry type, CircularBuffer (capacity 1000), privacy
  filtering (redacts passwords, auth tokens, sensitive URL params),
  cursor-based gap detection, async subscriber notification
- server.ts: /activity/stream SSE, /activity/history REST, handleCommand
  instrumented with command_start/command_end events
- 18 unit tests for filterArgs privacy, emitActivity, subscribe lifecycle

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: Chrome extension Side Panel + Conductor API proposal

Chrome extension (Manifest V3, sideload):
- Side Panel with live activity feed, @ref overlays, dark terminal aesthetic
- Background worker: health polling, SSE relay, ref fetching
- Popup: port config, connection status, side panel launcher
- Content script: floating ref panel with @ref badges

Conductor API proposal (docs/designs/CONDUCTOR_SESSION_API.md):
- SSE endpoint for full Claude Code session mirroring in Side Panel
- Discovery via HTTP endpoint (not filesystem — extensions can't read files)

TODOS.md: add $B watch, multi-agent tabs, cross-platform CDP, Web Store publishing.
Mark CDP mode as shipped.

* fix: detect Conductor runtime, skip osascript quit for sandboxed apps

macOS App Management blocks Electron apps (Conductor) from quitting
other apps via osascript. Now detects the runtime environment:
- terminal/claude-code/codex: can manage apps freely
- conductor: prints manual restart instructions + polls for 60s

detectRuntime() checks env vars and parent process. When Chrome needs
restart but we can't quit it, prints step-by-step instructions and
waits for the user to restart Chrome with --remote-debugging-port.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: detect Conductor via actual env vars (CONDUCTOR_WORKSPACE_NAME)

Previous detection checked CONDUCTOR_WORKSPACE_ID which doesn't exist.
Conductor sets CONDUCTOR_WORKSPACE_NAME, CONDUCTOR_BIN_DIR, CONDUCTOR_PORT,
and __CFBundleIdentifier=com.conductor.app. Check these FIRST because
Conductor sessions also have ANTHROPIC_API_KEY (which was matching claude-code).

* feat: connection status pill — floating indicator when gstack controls Chrome

Small pill in bottom-right corner of every page: "● gstack · 3 refs"
Shows when connected via CDP, fades to 30% opacity after 3s, full on hover.
Disappears entirely when disconnected.

Background worker now notifies content scripts on connect/disconnect state
changes so the pill appears/disappears without polling.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: Chrome requires --user-data-dir for remote debugging

Chrome refuses --remote-debugging-port without an explicit --user-data-dir.
Add userDataDir to BrowserBinary registry (macOS Application Support paths)
and pass it in both auto-launch and manual restart instructions.

Fix double-quoting in CLI manual restart instructions.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: Chrome must be fully quit before launching with --remote-debugging-port

Chrome refuses to enable CDP on its default profile when another instance
is running (even with explicit --user-data-dir). The only reliable path:
fully quit Chrome first, then relaunch with the flag.

Updated instructions to emphasize this clearly with verification step.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: bin/chrome-cdp — quit Chrome and relaunch with CDP in one command

Quits Chrome gracefully, waits for full exit, relaunches with
--remote-debugging-port, polls until CDP is ready. Usage: chrome-cdp [port]

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: use Playwright channel:chrome instead of broken connectOverCDP

Playwright's connectOverCDP hangs with Chrome 146 due to CDP protocol
version mismatch. Switch to channel:'chrome' which uses Playwright's
native pipe protocol to launch the system Chrome binary directly.

This is simpler and more reliable:
- No CDP port discovery needed
- No --remote-debugging-port or --user-data-dir hassles
- $B connect just works — launches real Chrome headed window
- All Playwright APIs (snapshot, click, fill) work unchanged

bin/chrome-cdp updated with symlinked profile approach (kept for
manual CDP use cases, but $B connect no longer needs it).

* feat: green border + gstack label on controlled Chrome window

Injects a 2px green border and small "gstack" label on every page
loaded in the controlled Chrome window via context.addInitScript().
Users can instantly tell which Chrome window Claude controls.

Also fixes close() for channel:chrome mode (uses browser.close()
not browser.disconnect() which doesn't exist).

* chore: cleanup chrome-launcher runtime detection, remove puppeteer-core dep

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* style(design): redesign controlled Chrome indicator

Replace crude green border + label with polished indicator:
- 2px shimmer gradient at top edge (green→cyan→green, 3s loop)
- Floating pill bottom-right with frosted glass bg, fades to 25%
  opacity after 4s so it doesn't compete with page content
- prefers-reduced-motion disables shimmer animation
- Much more subtle — looks like a developer tool, not broken CSS

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: document real browser mode + Chrome extension in BROWSER.md and README.md

BROWSER.md: new sections for connect/disconnect/focus commands,
Chrome extension Side Panel install, CDP-aware skills, activity streaming.
Updated command reference table, key components, env vars, source map.

README.md: updated /browse description, added "Real browser mode" to
What's New section.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: step-by-step Chrome extension install guide in BROWSER.md

Replace terse bullet points with numbered walkthrough covering:
developer mode toggle, load unpacked, macOS file picker tip (Cmd+Shift+G),
pin extension, configure port, open side panel. Added troubleshooting section.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: add Cmd+Shift+. tip for hidden folders in macOS file picker

macOS hides folders starting with . by default. Added both shortcuts:
Cmd+Shift+G (paste path directly) and Cmd+Shift+. (show hidden files).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: integrate hidden folder tips into the install flow naturally

Move Cmd+Shift+G and Cmd+Shift+. tips inline with the file picker
step instead of as a separate tip block after it.

* feat: auto-load Chrome extension when $B connect launches Chrome

Extension auto-loads via --load-extension flag — no manual chrome://extensions
install needed. findExtensionPath() checks repo root, global install, and dev
paths. Also adds bin/gstack-extension helper for manual install in regular
Chrome, and rewrites BROWSER.md install docs with auto-load as primary path.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: /connect-chrome skill — one command to launch Chrome with Side Panel

New skill that runs $B connect, verifies the connection, guides the user
to open the Side Panel, and demos the live activity feed. Extension auto-loads
via --load-extension so no manual chrome://extensions install needed.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: use launchPersistentContext for Chrome extension loading

Playwright's chromium.launch() silently ignores --load-extension.
Switch to launchPersistentContext with ignoreDefaultArgs to remove
--disable-extensions flag. Use bundled Chromium (real Chrome blocks
unpacked extensions). Fixed port 34567 for CDP mode so the extension
auto-connects.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: sync extension to DESIGN.md — amber accent, zinc neutrals, grain texture

Import design system from gstack-website. Update all extension colors:
green (#4ade80) → amber (#F59E0B/#FBBF24), zinc gray neutrals, grain
texture overlay. Regenerate icons as amber "G" monogram on dark background.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: sidebar chat with Claude Code — icon opens side panel directly

Replace popup flyout with direct side panel open on icon click. Primary
UI is now a chat interface that sends messages to Claude Code via file
queue. Activity/Refs tabs moved behind a debug toggle in the footer.
Command bar with history, auto-poll for responses, amber design system.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: sidebar agent — Claude-powered chat backend via file queue

Add /sidebar-command, /sidebar-response, and /sidebar-chat endpoints
to the browse server. sidebar-agent.ts watches the command queue file,
spawns claude -p with browse context for each message, and streams
responses back to the sidebar chat.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: remove duplicate gstack pill overlay, hide crash restore bubble

The addInitScript indicator and the extension's content script were both
injecting bottom-right pills, causing duplicates. Remove the pill from
addInitScript (extension handles it). Replace --restore-last-session with
--hide-crash-restore-bubble to suppress the "Chromium didn't shut down
correctly" dialog.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: state file authority — CDP server cannot be silently replaced

Hardens the connect/disconnect lifecycle:
- ensureServer() refuses to auto-start headless when CDP server is alive
- $B connect does full cleanup: SIGTERM → 2s → SIGKILL, profile locks, state
- shutdown() cleans Chromium SingletonLock/Socket/Cookie files
- uncaughtException/unhandledRejection handlers do emergency cleanup

This prevents the bug where a headless server overwrites the CDP server's
state file, causing $B commands to hit the wrong browser.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: sidebar agent streaming events + session state management

Enhance sidebar-agent.ts with:
- Live streaming of claude -p events (tool_use, text, result) to sidebar
- Session state file for BROWSE_STATE_FILE propagation to claude subprocess
- Improved logging (stderr, exit codes, event types)
- stdin.end() to prevent claude waiting for input
- summarizeToolInput() with path shortening for compact sidebar display

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: sidebar chat UI — streaming events, agent status, reconnect retry

Sidebar panel improvements:
- Chat tab renders streaming agent events (tool_use, text, result)
- Thinking dots animation while agent processes
- Agent error display with styled error blocks
- tryConnect() with 2s retry loop for initial connection
- Debug tabs (Activity/Refs) hidden behind gear toggle
- Clear chat button
- Compact tool call display with path shortening

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: server-integrated sidebar agent with sessions and message queue

Move the sidebar agent from a separate bun process into server.ts:
- Agent spawns claude -p directly when messages arrive via /sidebar-command
- In-memory chat buffer backed by per-session chat.jsonl on disk
- Session manager: create, load, persist, list sessions
- Message queue (cap 5) with agent status tracking (idle/processing/hung)
- Stop/kill endpoints with queue dismiss support
- /health now returns agent status + session info
- All sidebar endpoints require Bearer auth
- Agent killed on server shutdown
- 120s timeout detects hung claude processes

Eliminates: file-queue polling, separate sidebar-agent.ts process,
stale auth tokens, state file conflicts between processes.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: extension auth + token flow for server-integrated agent

Update Chrome extension to use Bearer auth on all sidebar endpoints:
- background.js captures auth token from /health, exposes via getToken msg
- background.js sets openPanelOnActionClick for direct side panel access
- sidepanel.js gets token from background, sends in all fetch headers
- Health broadcasts include token so sidebar auto-authenticates
- Removes popup from manifest — icon click opens side panel directly

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: self-healing sidebar — reconnect banner, state machine, copy button

Sidebar UI now handles disconnection gracefully:
- Connection state machine: connected → reconnecting → dead
- Amber pulsing banner during reconnect (2s retry, 30 attempts)
- Red "Server offline" banner with Reconnect + Copy /connect-chrome buttons
- Green "Reconnected" toast that fades after 3s on successful reconnect
- Copy button lets user paste /connect-chrome into any Claude Code session

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: crash handling — save session, kill agent, distinct exit codes

Hardened shutdown/crash behavior:
- Browser disconnect exits with code 2 (distinct from crash code 1)
- emergencyCleanup kills agent subprocess and saves session state
- Clean shutdown saves session before exit (chat history persists)
- Clear user message on browser disconnect: "Run $B connect to reconnect"

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: worktree-per-session isolation for sidebar agent

Each sidebar session gets an isolated git worktree so the agent's file
operations don't conflict with the user's working directory:
- createWorktree() creates detached HEAD worktree in ~/.gstack/worktrees/
- Falls back to main cwd for non-git repos or on creation failure
- Handles collision cleanup from prior crashes
- removeWorktree() cleans up on session switch and shutdown
- worktreePath persisted in session.json

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(qa): ISSUE-001 — disconnect blocked by CDP guard in ensureServer

$B disconnect was routed through ensureServer() which refused to start a
headless server when a CDP state file existed. Disconnect is now handled
before ensureServer() (like connect), with force-kill + cleanup fallback
when the CDP server is unresponsive.

* fix: resolve claude binary path for daemon-spawned agent

The browse server runs as a daemon and may not inherit the user's shell
PATH. Add findClaudeBin() that checks ~/.local/bin/claude (standard
install location), which claude, and common system paths. Shows a clear
error in the sidebar chat if claude CLI is not found.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: resolve claude symlinks + check Conductor bundled binary

posix_spawn fails on symlinks in compiled bun binaries. Now:
- Checks Conductor app's bundled binary first (not a symlink)
- Scans ~/.local/share/claude/versions/ for direct versioned binaries
- Uses fs.realpathSync() to resolve symlinks before spawning

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: compiled bun binary cannot posix_spawn — use external agent process

Compiled bun binaries fail posix_spawn on ALL executables (even /bin/bash).
The server now writes to an agent queue file, and a separate non-compiled
bun process (sidebar-agent.ts) reads the queue, spawns claude, and POSTs
events back via /sidebar-agent/event.

Changes:
- server.ts: spawnClaude writes to queue file instead of spawning directly
- server.ts: new /sidebar-agent/event endpoint for agent → server relay
- server.ts: fix result event field name (event.text vs event.result)
- sidebar-agent.ts: rewritten to poll queue file, relay events via HTTP
- cli.ts: $B connect auto-starts sidebar-agent as non-compiled bun process

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: loading spinner on sidebar open while connecting to server

Shows an amber spinner with "Connecting..." when the sidebar first opens,
replacing the empty state. After the first successful /sidebar-chat poll:
- If chat history exists: renders it immediately
- If no history: shows the welcome message

Prevents the jarring empty-then-populated flash on sidebar open.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: zero-friction side panel — auto-open on install, pill is clickable

Three changes to eliminate manual side panel setup:
- Auto-open side panel on extension install/update (onInstalled listener)
- gstack pill (bottom-right) is now clickable — opens the side panel
- Pill has pointer-events: auto so clicks always register (was: none)

User no longer needs to find the puzzle piece icon, pin the extension,
or know the side panel exists. It opens automatically on first launch
and can be re-opened by clicking the floating gstack pill.

* refactor: kill CDP naming, delete chrome-launcher.ts dead code

The connectCDP() method and connectionMode: 'cdp' naming was a legacy
artifact — real Chrome was tried but failed (silently blocks
--load-extension), so the implementation already used Playwright's
bundled Chromium via launchPersistentContext(). The naming was
misleading.

Changes:
- Delete chrome-launcher.ts (361 LOC) — only import was in unreachable
  attemptReconnect() method
- Delete dead attemptReconnect() and reconnecting field
- Delete preExistingTabIds (was for protecting real Chrome tabs we
  never connect to)
- Rename connectCDP() → launchHeaded()
- Rename connectionMode: 'cdp' → 'headed' across all files
- Replace BROWSE_CDP_URL/BROWSE_CDP_PORT env vars with BROWSE_HEADED=1
- Regenerate SKILL.md files for updated command descriptions
- Move BrowserManager unit tests to browser-manager-unit.test.ts

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: converge handoff into connect — extension loads on handoff

Handoff now uses launchPersistentContext() with extension auto-loading,
same as the connect/launchHeaded() path. This means when the agent
gets stuck (2FA, CAPTCHA) and hands off to the user, the Chrome
extension + side panel are available automatically.

Before: handoff used chromium.launch() + newContext() — no extension
After: handoff uses chromium.launchPersistentContext() — extension loads

Also sets connectionMode to 'headed' and disables dialog auto-accept
on handoff, matching connect behavior.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: gate sidebar chat behind --chat flag

$B connect (default): headed Chromium + extension with Activity + Refs
tabs only. No separate agent spawned. Clean, no confusion.

$B connect --chat: same + Chat tab with standalone claude -p agent.
Shows experimental banner: "Standalone mode — this is a separate
agent from your workspace."

Implementation:
- cli.ts: parse --chat, set BROWSE_SIDEBAR_CHAT env, conditionally
  spawn sidebar-agent
- server.ts: gate /sidebar-* routes behind chatEnabled, return 403
  when disabled, include chatEnabled in /health response
- sidepanel.js: applyChatEnabled() hides/shows Chat tab + banner
- background.js: forward chatEnabled from health response
- sidepanel.html/css: experimental banner with amber styling

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: file drop relay + $B inbox command

Sidebar agent now writes structured messages to .context/sidebar-inbox/
when processing user input. The workspace agent can read these via
$B inbox to see what the user reported from the browser.

File drop format:
  .context/sidebar-inbox/{timestamp}-observation.json
  { type, timestamp, page: {url}, userMessage, sidebarSessionId }

Atomic writes (tmp + rename) prevent partial reads. $B inbox --clear
removes messages after display.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: $B watch — passive observation mode

Claude enters read-only mode and captures periodic snapshots (every 5s)
while the user browses. Mutation commands (click, fill, etc.) are
blocked during watch. $B watch stop exits and returns a summary with
the last snapshot.

Requires headed mode ($B connect). This is the inverse of the scout
pattern — the workspace agent watches through the browser instead of
the sidebar relaying to it.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: add coverage for sidebar-agent, file-drop, and watch mode

33 new tests covering:
- Sidebar agent queue parsing (valid/malformed/empty JSONL)
- writeToInbox file drop (directory creation, atomic writes, JSON format)
- Inbox command (display, sorting, --clear, malformed file handling)
- Watch mode state machine (start/stop cycles, snapshots, duration)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: TODOS cleanup + Chrome vs Chromium exploration doc

- Update TODOS.md: mark CDP mode, $B watch, sidebar scout as SHIPPED
- Delete dead "cross-platform CDP browser discovery" TODO
- Rename dependencies from "CDP connect" to "headed mode"
- Add docs/designs/CHROME_VS_CHROMIUM_EXPLORATION.md memorializing
  the architecture exploration and decision to use Playwright Chromium

* docs: add Conductor Chrome sidebar integration design doc

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: sidebar-agent validates cwd before spawning claude

The queue entry may reference a worktree that was cleaned up between
sessions. Now falls back to process.cwd() if the path doesn't exist,
preventing silent spawn failures.

* fix: gen-skill-docs resolver merge + preamble tier gate + plan file discovery

The local RESOLVERS record in gen-skill-docs.ts was shadowing the imported
canonical resolvers, causing stale test coverage and preamble generators
to be used instead of the authoritative versions in resolvers/.

Changes:
- Merge imported RESOLVERS with local overrides (spread + override pattern)
- Fix preamble tier gate: tier 1 skills no longer get AskUserQuestion format
- Make plan file discovery host-agnostic (search multiple plan dirs)
- Add missing E2E tier entries for ship/review plan completion tests

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: ungate sidebar agent + raise timeout to 5 minutes (v0.12.0)

Sidebar chat is now always available in headed mode — no --chat flag needed.
Agent tasks get 5 minutes instead of 2, enabling multi-page workflows like
navigating directories and filling forms across pages.

Changes:
- cli.ts: remove --chat flag, always set BROWSE_SIDEBAR_CHAT=1, always spawn agent
- server.ts: remove chatEnabled gate (403 response), raise AGENT_TIMEOUT_MS to 300s
- sidebar-agent.ts: raise child process timeout from 120s to 300s

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: headed mode + sidebar agent documentation (v0.12.0)

- README: sidebar agent section, personal automation example (school parent
  portal), two auth paths (manual login + cookie import), DevTools MCP mention
- BROWSER.md: sidebar agent section with usage, timeout, session isolation,
  authentication, and random delay documentation
- connect-chrome template: add sidebar chat onboarding step
- CHANGELOG: v0.12.0 entry covering headed mode, sidebar agent, extension
- VERSION: bump to 0.12.0.0
- TODOS: Chrome DevTools MCP integration as P0

* feat: network idle, state persistence, iframe support, chain pipe format (v0.12.1.0) (#516)

* feat: network idle detection + chain pipe format

- Upgrade click/fill/select from domcontentloaded to networkidle wait
  (2s timeout, best-effort). Catches XHR/fetch triggered by interactions.
- Add pipe-delimited format to chain as JSON fallback:
  $B chain 'goto url | click @e5 | snapshot -ic'
- Add post-loop networkidle wait in chain when last command was a write.
- Frame-aware: commands use target (getActiveFrameOrPage) for locator ops,
  page-only ops (goto/back/forward/reload) guard against frame context.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: $B state save/load + $B frame — new browse commands

- state save/load: persist cookies + URLs to .gstack/browse-states/{name}.json
  File perms 0o600, name sanitized to [a-zA-Z0-9_-]. V1 skips localStorage
  (breaks on load-before-navigate). Load replaces session via closeAllPages().
- frame: switch command context to iframe via CSS selector, @ref, --name, or
  --url. 'frame main' returns to main frame. Execution target abstraction
  (getActiveFrameOrPage) across read-commands, snapshot, and write-commands.
- Frame context cleared on tab switch, navigation, resume, and handoff.
- Snapshot shows [Context: iframe src="..."] header when in frame.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: add tests for network idle, chain pipe format, state, and frame

- Network idle: click on fetch button waits for XHR, static click is fast
- Chain pipe: pipe-delimited commands, quoted args, JSON still works
- State: save/load round-trip, name sanitization, missing state error
- Frame: switch to iframe + back, snapshot context header, fill in frame,
  goto-in-frame guard, usage error

New fixtures: network-idle.html (fetch + static buttons), iframe.html (srcdoc)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: review fixes — iframe ref scoping, detached frame recovery, state validation

- snapshot.ts: ref locators, cursor-interactive scan, and cursor locator
  now use target (frame-aware) instead of page — fixes @ref clicking in iframes
- browser-manager.ts: getActiveFrameOrPage auto-recovers from detached frames
  via isDetached() check
- meta-commands.ts: state load resets activeFrame, elementHandle disposed after
  contentFrame(), state file schema validation (cookies + pages arrays),
  filter empty pipe segments in chain tokenizer
- write-commands.ts: upload command uses target.locator() for frame support
