Summary

Ports time-attack/gstack's fork into upstream with the hardening it needed to actually ship. The architecture's load-bearing insight: drop XCTest, drop the simulator, drop WebDriverAgent. Embed an HTTP server in the iOS app under test, drive it from a Mac-side bun daemon over the USB CoreDevice IPv6 tunnel. With the optional --tailnet flag, the Mac daemon also binds Tailscale and accepts authenticated remote calls — your $500 Mac mini + an iPhone you already have replaces the BrowserStack line item.

Five new skills:

  • /ios-qa — live-device QA with warm-start session cache, Tailscale opt-in, demo + recording modes
  • /ios-fix — autonomous bug fixer that captures a reproducing /state/snapshot before editing source
  • /ios-design-review — 10-dimension Apple HIG audit on a real device (mirrors /plan-design-review)
  • /ios-clean — convenience wrapper to strip DebugBridge SPM + #if DEBUG wiring
  • /ios-sync — regenerates accessors against latest upstream gstack templates

Mac-side daemon (ios-qa/daemon/) owns tailnet ingress so the iPhone never directly binds Tailscale. Single-instance flock + readiness protocol, fail-closed tailscaled LocalAPI probe, capability-tier allowlist (observe/interact/mutate/restore), 1h default session TTL (24h hard cap), audit log of every authenticated mutating tailnet request, hashed-identity attempts log.

Codex outside voice flagged 15 issues during plan review — every one is absorbed:

  • StateServer is loopback-only ALWAYS (Codex caught an earlier contradiction)
  • Boot token rotates within ~5s of daemon spawn (was: durable in os_log)
  • Default session TTL is 1h (was: 24h — too long for device control)
  • /auth/mint split into self-service + owner-granted (was: ambiguous mix)
  • Snapshot envelope carries _accessor_hash + _app_build_id (was: silent corruption on schema drift)
  • GET /state/snapshot returns ONLY fields marked @Snapshotable (was: default-leak)
  • Tailnet listener fails closed if tailscaled LocalAPI unreachable
  • X-Agent-Identity is display-only, never trusted for auth

Test Coverage

95 tests pass against the iOS subsystem alone:

Suite Count Coverage
Daemon unit/integration 67 session tokens, allowlist, auth-mint, single-instance race, tailscaled probe, audit/attempts logging, sanitize-replacer, route classification, full HTTP integration
Codegen (TS port mirroring SwiftPM tool) 20 parser handles all 3 fork-regex-failure-mode fixtures, composite cache key invalidates on Swift-version / tool-rev / source / platform changes
E2E skill flow 8 codegen + daemon + stub StateServer + Tailscale gating + capability tiers; 1 skipped behind GSTACK_HAS_IOS_DEVICE=1

bun test full free suite: EXIT=0.

Pre-Landing Review

Plan went through CEO review + eng review + Codex outside voice (D1-D10 all resolved with explicit user decisions). Codex flagged ~15 substantive concerns; 4 escalated to cross-model tension and resolved by user, 11 absorbed as plan corrections/hardening before any code was written. No critical gaps in the failure-modes registry.

Plan Completion

All scope items shipped: 5 skills (L1), Swift templates (L2), Mac daemon (L3), gen-accessors tool with TS port (L4), E2E test battery (L5), VERSION/CHANGELOG/AGENTS/README/docs (L6). Sequential L1→L6 per user direction. Plan file: ~/.claude/plans/system-instruction-you-are-working-humming-meteor.md.

TODOS

Deferred to TODOS.md per CEO review:

  • E5: Self-hosted GitHub Actions runner pattern (~30min CC)
  • E6: Live co-pilot SSE state-change feed (~6-8h CC)
  • E7: SwiftUI Preview farming (~3h CC)
  • E8: Cross-platform StateServer pattern (Mac/Android/watchOS/tvOS) — long-term

Test plan

  • bun test ios-qa/ passes (94 pass + 1 skip)
  • bun test test/skill-e2e-ios.test.ts passes (7 pass + 1 skip)
  • bun run gen:skill-docs --host all --dry-run passes (no drift)
  • bun test full free suite EXIT=0
  • Manual: with iPhone connected, run /ios-qa against a fixture app, watch the blue border appear and a screen pass complete

Documentation

  • README.md — added gstack-ios-qa-daemon and gstack-ios-qa-mint to the standalone binaries table; iOS skill row now links to the new how-to.
  • AGENTS.md — added companion CLI table under the iOS device-farm section + how-to link.
  • docs/howto-ios-testing-with-gstack.md — new end-to-end walkthrough (~190 lines): prerequisites, architecture diagram, install the templates, build + install + launch on the device, spin up the daemon, raw HTTP surface table, capability tiers, optional Tailscale remote-agent mode via gstack-ios-qa-mint, /ios-clean before release, common failures.

Documentation Debt

The Diataxis coverage audit surfaced this gap:

  • ⚠️ Critical (now closed): gstack-ios-qa-daemon and gstack-ios-qa-mint had zero coverage outside ios-qa/SKILL.md. Fixed by this commit (reference rows in README + AGENTS, how-to in docs/).
  • Remaining: no tutorial-quadrant doc for first-time iOS QA users (the how-to assumes you know what an SPM dependency is). Not load-bearing for shipping this PR.

Authors ios-qa, ios-fix, ios-design-review, ios-clean, ios-sync as upstream gstack skills. Each follows the standard SKILL.md.tmpl pattern with preamble-tier:3 frontmatter. The fork at time-attack/gstack shipped these but as byte-identical .md/.tmpl pairs that wouldn't pass skill-docs.yml — this commit fixes that by authoring proper templates and regenerating through gen-skill-docs.
…ural Release guard

StateServer is loopback-only (::1 + 127.0.0.1) with boot-token rotation, per-device session lock (sliding on mutations only), snapshot/restore with schema-hash envelope, and 1MB body cap. DebugOverlay v2 has animated brand border + agent attribution chip (display-only) + recording watermark. Package.swift enforces structural Release-build exclusion via .when(configuration: .debug). Includes Tailscale ACL example doc.
…SB proxy

On-demand daemon spawns when /ios-qa needs it (single-instance flock + readiness protocol). Owns tailnet ingress: fail-closed tailscaled LocalAPI probe, dual-track /auth/mint (self-service for allowlisted identities, owner-granted via CLI), capability-tier allowlist (observe/interact/mutate/restore), 1h default session TTL (24h hard cap), audit log of every authenticated mutating tailnet request, hashed-identity attempts log. iOS StateServer never directly binds tailnet — identity validation lives Mac-side because iPhones can't reach tailscaled. 67 unit/integration tests covering session-lock concurrency, capability enforcement, fail-closed probe, identity canonicalization, body limits, and boot-token leak proofs.
Replaces fork's regex-based codegen with SwiftPM swift-syntax tool (production) plus a TS port (test + fast first-run). Composite cache key: sha256(source || swift_version || tool_git_rev || platform_triple). Codex flagged that source-only hash misses generator-logic changes — this hash invalidates correctly across all four dimensions. 20 tests cover the 3 known regex failure modes (computed properties, generics, multi-line types) plus full cache hit/miss/prune coverage.
8 E2E scenarios: codegen against SwiftUI fixture, daemon spawn + stub StateServer, schema-mismatch rejection, full agent loop, multi-agent contention, tailnet allowlist gating, capability-tier enforcement. Registered as gate-tier in E2E_TOUCHFILES + E2E_TIERS so diff-based selection picks up iOS work without slowing every PR.

…opback bind fix

Closes the gap from prior commits where E2E tests stubbed the Swift StateServer
in TypeScript. Now there's a real SwiftPM fixture at test/fixtures/ios-qa/FixtureApp/
that compiles the production templates and runs an XCTest suite against the
actual StateServer implementation. Three new test layers:

- swift build invariants (periodic-tier): debug-config build succeeds, XCTest
  suite passes (validates real Swift impl over Foundation + Network), release-config
  build has zero DebugBridge symbols (structural #if DEBUG gate works end-to-end).

- Real-device probe (periodic-tier, GSTACK_HAS_IOS_DEVICE=1): devicectl can list
  + pair the connected iPhone. Surfaces actionable instructions when the trust
  dialog hasn't been confirmed yet.

- Fixture sources copied from ios-qa/templates/ — Package.swift splits the
  bridge into DebugBridgeCore (Foundation+Network, cross-platform) and
  DebugBridgeUI (UIKit/SwiftUI, iOS-only) so swift build can validate the
  bulk of the production code on macOS without an iPhone or simulator.

Also fixes a real bug the XCTest unit suite caught: NWListener with
requiredLocalEndpoint on params silently fails to bind for listening (it's
an outbound-connection concept). Replaced with .requiredInterfaceType=.loopback
+ .acceptLocalOnly=true + a per-connection peer-address check. The fork's
inherited code had this bug; we shipped it untouched in v1.41.0.0 and the
new XCTest suite caught it immediately.

…ith #1574

The version-gate workflow flagged a collision: PR #1574
(garrytan/colombo-v3) already claims v1.41.0.0, and #1592
(fix/audit-critical-high-bugs) claims v1.41.1.0. Per CLAUDE.md's
workspace-aware ship rule, queue-advancing past a claimed version
within the same bump level is permitted — MINOR work landing on top
of a queued MINOR still reads as MINOR relative to main.

Util's suggested next slot is v1.42.0.0; taking it. CHANGELOG entry
header bumped + dated 2026-05-19; entry body unchanged (same wave
content, same credit list).

End-to-end verification on a connected iPhone 17 Pro Max via CoreDevice
tunnel exposed three bugs the TS-stubbed and macOS-XCTest layers missed:

1. acceptLocalOnly=true was too tight. Network.framework's "local" gate
   only allows ::1 / 127.0.0.1, silently dropping CoreDevice tunnel peers
   (the very transport the architecture is designed for). The device log
   showed "Ignoring non-local connection from fd72:8347:2ead::2" — the
   Mac's tunnel-side address. Replaced with explicit per-connection ULA
   gate (RFC 4193 fc00::/7) in isLoopbackPeer.

2. DebugBridgeCore (Foundation+Network) referenced DebugOverlayWindow
   which lives in DebugBridgeUI (UIKit). Backwards module dep. Compiled
   on macOS only because canImport(UIKit) stripped it; broke on iOS.
   Moved the overlay install responsibility to the consuming app's
   wiring (DebugBridgeWiring.swift.template already shows the pattern).

3. @observable macro + @Snapshotable property wrapper conflict. Both
   try to synthesize backing storage; can't coexist on the same property.
   The production guidance is: nest snapshot-eligible state in a struct
   inside an ObservableObject (or use the canonical-state-struct atomicity
   strategy). Fixture switched to a plain class to demonstrate.

Smoke loop on the real device now passes 7/8 endpoints:
- /healthz (200), /tap unauth (401), /auth/rotate (200), boot-token reuse
  rejected (401), /session/acquire (200), /state/snapshot (200 with schema
  envelope), /session/release (200). /tap with valid session returns 200
  HTTP + op:false because the FixtureApp doesn't wire MutationBridge.resolver
  to a real UI tap — expected for a minimal fixture; the production wiring
  template handles it.

Also adds:
- test/fixtures/ios-qa/FixtureApp/Sources/FixtureApp/FixtureAppApp.swift
  (SwiftUI @main entry that boots StateServer)
- test/fixtures/ios-qa/FixtureApp/Sources/FixtureApp/Info.plist
- test/fixtures/ios-qa/FixtureApp/project.yml (xcodegen project spec
  with DEVELOPMENT_TEAM 623FYQ2M88, bundle id com.gstack.iosqa.fixture)

End-to-end verified path:
  xcodegen generate
  xcodebuild -allowProvisioningUpdates -allowProvisioningDeviceRegistration
  devicectl device install app
  devicectl device process launch
  devicectl device copy from --source tmp/gstack-ios-qa.token
  curl -6 http://[<corodevice-ipv6>]:9999/...
Closes two layers of the device-control gap:

L1 — Mac daemon's tunnelProvider is now real, not a stub. New files:
- ios-qa/daemon/src/devicectl.ts: thin wrappers around `xcrun devicectl`
  (list, info, launch, install, copy-from) with spawn+resolve injection
  for unit testability.
- ios-qa/daemon/src/tunnel-bootstrap.ts: orchestrates find-device →
  launch-app → resolve IPv6 → wait-for-healthz → copy-boot-token →
  POST /auth/rotate → return DeviceTunnel with rotated bearer.
- ios-qa/daemon/test/tunnel-bootstrap.test.ts: 7 tests covering every
  error branch (no_devices, no_paired_device, device_locked,
  state_server_unreachable, resolve_failed, happy path, explicit-udid).
- index.ts wired to use bootstrapTunnel() when running as CLI; tests
  keep using injected stubs.

L2 — In-process touch synthesis for non-UIControl widgets. New target
in the fixture SPM package:
- DebugBridgeTouch (Objective-C): KIF-derived UITouch + IOHIDEvent
  synthesis. Loads IOKit dynamically via dlopen/dlsym (IOKit is a
  private framework on iOS, can't link statically). Uses iOS 18+
  _UIHitTestContext for SwiftUI hit-testing. Public Swift-callable
  API: DebugBridgeTouch.sendTap(at:in:). MIT-attributed to
  kif-framework/KIF.
- DebugBridgeUI/Bridges.swift: rewritten MutationBridge.handleTap to
  delegate to DebugBridgeTouch. ScreenshotBridge + ElementsBridge
  implementations also land here.
- FixtureApp/Sources/FixtureApp/FixtureAppApp.swift: wires the bridges
  on app launch under #if DEBUG.

Real-iPhone evidence (Conductor sandbox → CoreDevice IPv6 → live app):
- /healthz returns 200 with on-device JSON body
- /screenshot returns 427KB PNG that decodes to your actual phone screen
- Boot-token rotation kills the original token (401 boot_token_invalid
  on reuse — the load-bearing security property verified live)
- Session lock + auth gate (401/423/200 paths all work)
- Schema-versioned state envelope (_schema_version + _accessor_hash)

Known partial: synthesized UITouch reaches SwiftUI's host view per
device-side syslog ("non-local connection from fd...:2" earlier showed
the per-connection peer gate working), and HTTP returns 200 ok:true,
but SwiftUI Button onTap handler doesn't fire. UIControl widgets DO
work via UIControl.sendActions. Next step is attaching lldb to the
live app on device to diagnose which validation SwiftUI's gesture
recognizer is failing. The architectural primary path
(`POST /state/<key>` to mutate @Snapshotable fields) is unaffected
and is the recommended control vector.

Documented sources for the KIF-derived synthesis:
- https://github.com/kif-framework/KIF (MIT)
- UITouch-KIFAdditions.m: init flow with _setLocationInWindow:,
  setGestureView:, _setIsFirstTouchForView:
- IOHIDEvent+KIF.m: digitizer event construction
- iOS 18+ _UIHitTestContext path for SwiftUI hit-testing
DBT_HitTestView was filtering _hitTestWithContext: results by
isKindOfClass:UIView and dropping the new SwiftUI.UIKitGestureContainer
(a UIResponder, not UIView). SwiftUI Buttons live behind that container
on iOS 18+, so every synthesized tap returned ok:true but onTap never
fired.

Mirror KIF PR #1323: return id, pass the responder through to
UITouch.setView: directly (the setter accepts non-UIView responders).

Verified: real iPhone 17 Pro Max, iOS 26.5, FixtureApp counter
incremented 0 → 1 → 4 over four /tap requests at the button location.

…ement (24 bisect commits) (#1594)

* fix(gstack-paths): guard CLAUDE_PLUGIN_DATA against cross-plugin contamination (#1569)

gstack-paths previously trusted CLAUDE_PLUGIN_DATA as a fallback for
GSTACK_STATE_ROOT whenever GSTACK_HOME was unset. When another plugin
(e.g. Codex) persists its own CLAUDE_PLUGIN_DATA into the session env
via CLAUDE_ENV_FILE, gstack picked it up and wrote checkpoints,
analytics, and learnings into that plugin's directory. Anyone with the
Codex plugin installed alongside gstack hit this silently.

Fix: guard the CLAUDE_PLUGIN_DATA branch so it only fires when
CLAUDE_PLUGIN_ROOT confirms we're running as the gstack plugin (path
contains "gstack"). Skill installs fall through to \$HOME/.gstack.

Contributed by @ElliotDrel via #1570. Closes #1569.

* fix(gbrain-sync): sourceLocalPath handles wrapped {sources:[...]} shape from gbrain v0.20+

gbrain v0.20+ changed `gbrain sources list --json` to return
{sources: [...]} instead of a flat array. sourceLocalPath crashed
upstream with `list.find is not a function` on every /sync-gbrain
invocation against modern gbrain. Accept both shapes for
forward/backward compat, matching probeSource/sourcePageCount in
lib/gbrain-sources.ts.

Contributed by @jakehann11 via #1571. Closes #1567. Supersedes #1564
(@tonyjzhou, same fix, different shape — credit retained).

* fix(brain-context-load): probe gbrain via execFile, not shell builtin (#1559)

gbrainAvailable() used `execFileSync("command", ["-v", "gbrain"])`,
which fails in any environment where the `command` builtin isn't on
the spawned process's PATH (most non-interactive shells). The probe
then reported gbrain as missing even when it was installed, and
context-load silently skipped vector/list queries.

Fix: probe `gbrain --version` directly with a 500ms timeout (matching
the rest of the file's MCP_TIMEOUT_MS). Same semantics, works
everywhere execFile works.

Contributed by @jbetala7 via #1560. Closes #1559.

* test(gbrain-doctor): pin schema_version:2 doctor parse path (#1418)

Adds an exec-path regression test that runs a fake gbrain shim emitting
the v0.25+ doctor JSON shape (schema_version: 2, status: "warnings",
exit 1 for health_score < 100, no top-level `engine` field). Confirms
freshDetectEngineTier recovers stdout from the non-zero exit and falls
back to GBRAIN_HOME/config.json for the engine label.

The pre-existing test for #1415 only stripped gbrain from PATH; this
test exercises the actual doctor parse path, closing the gap that
codex's plan review flagged.

Also documents the schema_version separation in
lib/gbrain-local-status.ts: the local CacheEntry stays at version 1,
distinct from the doctor-output schema_version which we accept across
versions in gstack-memory-helpers.

Closes #1418 (credit @mvanhorn for surfacing the doctor + schema_v2
collapse). The fix landed pre-emptively in v1.29.x; this commit pins
it with a stronger test.

* test(memory-ingest): pin put_page regression + scrub stale name from --help and comments (#1346)

#1346 reported that gstack-memory-ingest still called the renamed
gbrain put_page subcommand on gbrain v0.18+. The actual code migrated
to `gbrain put` and later to batch `gbrain import <dir>` before this
report landed — only documentation lag remained.

This commit:
- Updates the --help string ("Skip gbrain put calls (still updates
  state file)") so user-facing docs match the shipped subcommand
- Updates two inline comments that still referenced the old name
- Adds test/memory-ingest-no-put_page.test.ts: a regression pin that
  strips comments from bin/gstack-memory-ingest.ts and fails the build
  if "put_page" appears in any active code or string literal, plus a
  sanity check that the file still calls a supported gbrain page-write
  verb (put or import)

Closes #1346. Reporter @kylma-code surfaced the doc lag; the original
code migration credit is on the v1.27.x wave.

* fix(resolvers): rewrite all gbrain put_page instructions to canonical put <slug>

scripts/resolvers/gbrain.ts emitted user-facing copy-paste instructions
using the renamed `gbrain put_page` subcommand across 10 skills
(office-hours, investigate, plan-ceo-review, retro, plan-eng-review,
ship, cso, design-consultation, fallback, entity-stub). Every gstack
user copying those snippets hit "unknown command: put_page" on gbrain
v0.18+.

This commit:
- Rewrites all 10 instruction templates to use `gbrain put <slug>
  --content "$(cat <<EOF...EOF)"` with title/tags moved into YAML
  frontmatter inside --content, matching the v0.18+ subcommand shape
- Updates README.md and USING_GBRAIN_WITH_GSTACK.md "common commands"
  table to reference `gbrain put` and `gbrain get`
- Adds test/resolvers-gbrain-put-rewrite.test.ts pinning two
  invariants: (a) resolver source ships only canonical instructions,
  (b) every tracked SKILL.md file is free of `gbrain put_page`

CHANGELOG entries are deliberately left untouched (historical record).

* fix(build): extract package.json build to scripts/build.sh for Windows Bun compat (#1538, #1537, #1530, #1457, #1561)

Bun's Windows shell parser rejects multiple constructs the inline
package.json build chain used: brace groups `{ cmd; }`, subshells with
redirection `( git ... ) > path/.version`, and (in Bun 1.3.x) subshells
near redirections in general. Every Windows install + every
auto-upgrade since v1.34.2.0 has failed on `bun run build`.

Extracts the build chain to scripts/build.sh and the .version writes to
scripts/write-version-files.sh. POSIX-portable, no Bun shell parsing
involved. Also adds Windows-specific bun.exe handling for non-ASCII
PATHs (a separate Windows footgun where Bun's --compile fails when the
binary lives under a path with non-ASCII chars).

Updates test/build-script-shell-compat.test.ts to assert the new shape:
no subshells with redirections anywhere in the build chain, and build
delegates to scripts/build.sh which delegates .version writes.

* fix(windows): .exe glob in .gitignore + .exe extension resolution in find-browse (#1554)

bun build --compile on Windows appends .exe to the output filename,
producing browse.exe instead of browse. find-browse's existsSync probe
only checked the bare path and returned null on Windows even when the
binary was correctly built. .gitignore similarly only excluded the
bare bin/gstack-global-discover path, leaving the .exe variant
tracked.

This commit:
- .gitignore: changes `bin/gstack-global-discover` →
  `bin/gstack-global-discover*` so the Windows .exe variant is ignored
- browse/src/find-browse.ts: adds isExecutable + findExecutable helpers
  that fall back to .exe/.cmd/.bat probing on Windows, mirroring the
  same helper already in make-pdf/src/browseClient.ts and pdftotext.ts

* ci(windows): add fresh-install E2E gate that runs bun run build on windows-latest

Adds .github/workflows/windows-setup-e2e.yml as the gate that catches
Bun shell-parser regressions in the build chain before they reach
users. Triggers on PRs touching package.json, scripts/build.sh,
scripts/write-version-files.sh, setup, browse cli/find-browse, or
gstack-paths.

What it verifies:
1. bun run build completes on Windows (the previously-broken path that
   #1538/#1537/#1530/#1457/#1561 reported)
2. All compiled binaries land on disk (browse.exe, find-browse.exe,
   design.exe, gstack-global-discover.exe)
3. find-browse resolves to the .exe variant on Windows (regression
   gate for #1554)
4. gstack-paths returns non-empty GSTACK_STATE_ROOT/PLAN_ROOT/TMP_ROOT
   on Windows (regression gate for #1570)

Complements the existing windows-free-tests.yml (curated unit subset);
this new workflow exercises the install path itself.

* fix(codex): move diff scope into prompt instead of --base (Codex CLI 0.130+ argv conflict) (#1209)

Codex CLI ≥ 0.130.0 rejects passing a custom prompt and --base together
(mutually exclusive at argv level). Every /codex review, /review, and
/ship structured Codex review call ended with an argv error before the
model ran.

Fix: scope the diff in prompt text using
"Run git diff origin/<base>...HEAD 2>/dev/null || git diff <base>...HEAD"
instead of `--base <base>`. Preserves the filesystem boundary
instruction across all invocations and keeps Codex's review prompt
tuning.

Touches:
- codex/SKILL.md.tmpl + regenerated codex/SKILL.md
- scripts/resolvers/review.ts + regenerated review/SKILL.md, ship/SKILL.md
- test/gen-skill-docs.test.ts: new regression that fails if any of the
  five known files still contain the prompt+--base shape
- test/skill-validation.test.ts: corresponding negative + positive pin
  on the rendered SKILL.md files

Contributed by @jbetala7 via #1209. Closes #1479. Supersedes #1527

* fix(review): diff from git merge-base, not git diff origin/<base> (#1492)

git diff origin/<base> shows everything since the common ancestor in
both directions — it includes commits that landed on origin/<base>
after this branch was created as deletions. That made /review and
/ship's pre-landing structured review report inflated diff totals and
flagged "removed" code that was actually still present in the working
tree.

Fix: compute DIFF_BASE via git merge-base origin/<base> HEAD and diff
the working tree against that point. Same coverage of uncommitted
edits, no phantom deletions from out-of-order base advancement.

Applies to /review's Step 1 (diff existence check), Step 3 (get the
diff), the build-on-intent scope-creep check, the structured review
DIFF_INS/DIFF_DEL stats, and the Claude adversarial subagent prompt.
Same change flows into ship/SKILL.md via the shared resolver.

Touches:
- review/SKILL.md.tmpl + regenerated review/SKILL.md, ship/SKILL.md

* test(codex): pin filesystem-boundary preservation across all codex review surfaces (#1503, #1522)

#1503 reported that the bare codex review --base path stripped the
filesystem boundary instruction, letting Codex spend tokens reading
.claude/skills/ and agents/. #1522 proposed adding a skill-path
detector that switched to the custom-instructions route when the diff
touched skill files.

After C10 (#1209) restructured codex review to always carry the
boundary in the prompt (the prompt+--base argv conflict forced the
restructure), the skill-path detector becomes redundant — every
default call already preserves the boundary.

This commit pins the post-#1209 invariant with a test that fails the
build if any future refactor strips the boundary from codex/SKILL.md,
review/SKILL.md, or ship/SKILL.md. Closes #1503 by regression test.

#1522 (@genisis0x) is superseded by #1209 (the prompt rewrite covers
its safety concern); credit retained in CHANGELOG.

* fix(skills): use command -v instead of which for codex detection (#1197)

`which` is not on PATH in every shell — some Windows shells, BusyBox-
only containers, and minimal CI images all fail when skills probe
codex availability via `which codex`. `command -v` is a POSIX builtin
and always available where the skill is running.

Touched:
- codex/SKILL.md.tmpl: CODEX_BIN=$(command -v codex || echo "")
- scripts/resolvers/review.ts and scripts/resolvers/design.ts:
  3 + 3 sites each rewritten to `command -v codex >/dev/null 2>&1`
- Regenerated all 10 affected SKILL.md files (codex, review, ship,
  design-consultation, design-review, office-hours, plan-ceo-review,
  plan-design-review, plan-devex-review, plan-eng-review)
- test/skill-validation.test.ts: updated pin + defensive regression
  test that fails if `which codex` returns to codex/SKILL.md
- test/skill-e2e-plan.test.ts: updated summary regex

* fix(codex): surface non-zero exits so wrappers stop reading as silent stalls (#1467, #1327)

When codex exits non-zero (parse errors, arg-shape breaks, model API
errors that propagate as non-zero status), the calling agent
previously saw an empty output and burned 30-60 minutes misdiagnosing
as a silent model/API stall. The hang-detection block only caught
exit 124 (the timeout-wrapper signal).

Adds elif blocks in all four codex invocation sites (Review default,
Challenge, Consult new-session, Consult resume) that:
- Echo "[codex exit N] <stderr first line>" to stdout
- Indent the first 20 stderr lines for inline context
- Log codex_nonzero_exit telemetry tagged with the call site

* fix(design): disclose OpenAI key source + warn on cwd .env match (#1278, closes #1248)

The design binary previously called process.env.OPENAI_API_KEY without
checking where the key came from. If a user ran $D inside someone
else's project that had OPENAI_API_KEY in its .env, the resulting
generation billed that project's account. Silent and irreversible.

Fix: resolveApiKeyInfo() returns both the key and its source. When the
env-var path matches an OPENAI_API_KEY entry in the current
directory's .env, .env.<NODE_ENV>, or .env.local file, we set a
warning. requireApiKey() prints "Using OpenAI key from <source>" plus
the warning before the run — never the key itself.

Adds 6 unit tests covering: config-vs-env precedence, env-only (no
match), env+cwd .env match, quoted/exported values, value-mismatch
(no false positive), and the no-leak invariant for requireApiKey
stderr output.

* fix(browse): guard full-page screenshots against Anthropic vision API >2000px brick (#1214)

Full-page screenshots of tall pages routinely exceeded 2000px on the
longest dimension, silently bricking the agent's session: the
resulting base64 reached the Anthropic vision API which rejected the
oversized image, leaving the agent burning turns on a useless blob
with no stderr trace from the browse side.

Adds browse/src/screenshot-size-guard.ts as a shared helper:
- guardScreenshotBuffer(buf) → downscales in-memory if max(w,h) > 2000
- guardScreenshotPath(path) → file-mode variant that rewrites in place
- Aspect ratio preserved via sharp's resize fit:inside
- Stderr diagnostic on any downscale so callers can see when it fired
- Lazy sharp import so non-screenshot paths pay no startup cost

Wires the guard into all three full-page callsites codex review
flagged:
- browse/src/snapshot.ts: annotated + heatmap fullPage captures
- browse/src/meta-commands.ts: screenshot command (path + base64
  fullPage modes) plus the responsive 3-viewport sweep
- browse/src/write-commands.ts: prettyscreenshot fullPage path

Covers seven unit cases (pass-through, downscale, aspect ratio,
exactly-2000px edge, file-mode rewrite) plus a static invariant test
that fails the build if any of the three callsites stops importing the
guard.

Closes #1214.

* feat(security): add Node sidecar entry for L4 prompt-injection classifier (#1370)

The L4 TestSavant classifier in browse/src/security-classifier.ts
can't be imported into the compiled browse server (onnxruntime-node
dlopen fails from Bun's compile extract dir per CLAUDE.md). The agent
that used to host it (sidebar-agent.ts) was removed when the PTY
proved out — leaving the classifier file shipped but with zero
callers. Exactly the gap codex flagged in #1370.

Adds browse/src/security-sidecar-entry.ts: a Node script that runs the
classifier as a subprocess of the browse server. It reads NDJSON
requests from stdin and writes id-correlated NDJSON responses to
stdout, supporting:
  - op: "scan-page-content" — full L4 classifier scan
  - op: "ping" — liveness probe for the client's health check
  - op: "status" — classifier readiness (used by /pty-inject-scan to
    surface l4 { available: bool } in its response)

Plus browse/src/find-security-sidecar.ts: a resolver that locates
node + the bundled JS entry (browse/dist/security-sidecar.js, built in
a follow-up package.json change) or falls back to the dev TS entry.
Returns null cleanly when node isn't on PATH so the calling endpoint
can degrade per D7 (extension WARN + user confirm).

C17 of the security-stack wave. C18 adds the IPC client + lifecycle
management; C19 wires the endpoint; C20 routes the extension through it.

* feat(security): sidecar IPC client with lifecycle + circuit breaker (#1370)

Adds browse/src/security-sidecar-client.ts to manage the Node L4
classifier subprocess from the compiled browse server:

- Lazy spawn on first scan; reuses the same process across requests
- Id-correlated request/response via NDJSON over stdio
- 5s default per-scan timeout; 64KB payload cap (short-circuits before
  spawn so oversized requests don't waste a process)
- 3-in-10-minutes respawn cap → trips circuit breaker; subsequent
  scans throw immediately so the /pty-inject-scan endpoint can surface
  l4 { available: false } to the extension and degrade to WARN+confirm
- process.on('exit') sends SIGTERM to the child for clean teardown
- isSidecarAvailable() lets the endpoint probe before scan calls so
  the response shape reflects degraded mode honestly

Unit tests cover the payload cap, the availability probe, and the
breaker-doesn't-crash invariant under repeated rejected calls.

C18 of the security-stack wave. C19 adds POST /pty-inject-scan; C20
routes the extension through it.

* feat(security): add POST /pty-inject-scan endpoint for pre-PTY-inject scans (#1370)

The sidebar's gstackInjectToTerminal callers (toolbar Cleanup,
Inspector "Send to Code") were piping page-derived text directly into
the live claude PTY with ZERO classifier processing — the gap codex
flagged in #1370. The documented sidebar security stack had a hole
the size of every Cleanup-button click.

Adds POST /pty-inject-scan to browse/src/server.ts:
- Local-only binding (NOT in TUNNEL_PATHS — tunnel attempts get the
  general 404 path; never reaches the scan logic)
- Root-token auth via existing validateAuth() — 401 on unauth
- 64KB request cap → 413 + payload-too-large body
- 5s scan timeout via sidecar client
- URL-blocklist forced to BLOCK in PTY context (page-derived REPL
  input is higher-risk than ordinary tool output)
- L4 ML classifier via the sidecar when available; degrades to WARN
  per D7 when sidecar is unavailable
- Response goes through JSON.stringify(..., sanitizeReplacer) per
  v1.38.0.0 Unicode-egress hardening
- Imports only from security-sidecar-client.ts, never directly from
  security-classifier.ts (which would brick the compiled Bun binary)

Seven static-invariant tests pin the POST verb, auth gate, 64KB cap,
tunnel-listener exclusion, sanitizeReplacer wrapping, l4 availability
shape, and the no-direct-classifier-import rule.

C19 of the security-stack wave. C20 routes the extension through it;
C21 adds the invariant AST check.

* feat(extension): route gstackInjectToTerminal through /pty-inject-scan (#1370)

Closes the documented-vs-shipped gap codex flagged in #1370. The
sidebar's two PTY-injection call sites (Inspector "Send to Code" and
toolbar Cleanup) now pre-scan via the new /pty-inject-scan endpoint
before writing to the live claude REPL.

Adds window.gstackScanForPTYInject(text, origin) to
extension/sidepanel-terminal.js:
- Async, returns { allow, verdict, reasons, l4 }
- POST to /pty-inject-scan with the existing root-token auth
- WARN+confirm on scan failure (network down, sidecar absent, etc.)
  rather than silent PASS — D7 honest-degradation

gstackInjectToTerminal stays synchronous, returns boolean. Per D6:
keeping the inject sync means existing `const ok = ...?.()` callers
don't break, and the invariant test in
test/extension-pty-inject-invariant.test.ts can statically pin that
every call goes through the scan first.

extension/sidepanel.js call sites updated:
- inspectorSendBtn click → await scan, BLOCK drops + WARN prompts via
  window.confirm, PASS injects silently
- runCleanup() → same flow. Static cleanup prompt always PASSes but
  still routes through scan to honor the invariant.

C20 of the security-stack wave. C21 adds the static invariant test.

* test(security): invariant — extension PTY inject must be scan-gated (#1370)

Static-analysis invariant test that fails the build if any
extension/*.js path calls window.gstackInjectToTerminal without a
preceding window.gstackScanForPTYInject in the same enclosing
function. Closes the documented-vs-shipped gap codex demanded a
machine check on.

Rules:
- Rule 1: any file that calls inject must also reference scan
- Rule 2: in the enclosing function (function declaration, arrow,
  async (), event handler), a scan call must appear before the inject
  call by source position
- Exemption: sidepanel-terminal.js (the file that DEFINES the inject
  function) is exempt from Rule 2 since the definition is not a call

Plus two structural checks:
- sidepanel-terminal.js defines both the inject and scan functions
- inject stays SYNCHRONOUS (no `async` modifier) per D6 — async would
  silently break the `const ok = ...?.()` pattern at every caller

C21 of the security-stack wave. The sidecar architecture (#1370) is
complete: server-side L1-L3 + L4-via-sidecar (C17+C18+C19), extension
pre-scan wiring (C20), and now the regression gate (C21).

* feat(browse): opt-in extended stealth mode with 6 detection-vector patches (#1112)

Rebases @garrytan's PR #1112 (Apr 2026, abandoned) onto the current
browse/src/stealth.ts contract. The existing minimal "codex narrowed"
stealth (webdriver-mask + AutomationControlled launch arg) stays the
default. PR #1112's six additional patches are added behind an opt-in
GSTACK_STEALTH=extended env flag.

Extended-mode patches (applied AFTER the default mask, in order):
  1. delete navigator.webdriver from prototype (not just the getter —
     detectors check `"webdriver" in navigator`)
  2. WebGL renderer spoof to Apple M1 Pro (SwiftShader was the #1
     software-GPU tell in containers)
  3. navigator.plugins returns a PluginArray-prototype-passing array
     with MimeType objects and namedItem()
  4. window.chrome populated with chrome.app, chrome.runtime,
     chrome.loadTimes(), chrome.csi() with realistic shapes
  5. navigator.mediaDevices backfilled when headless drops it
  6. CDP cdc_*-prefixed window globals cleared

Why opt-in: the default mode's contract is fingerprint CONSISTENCY,
which protects against detectors that flag spoofing mismatch. Extended
mode actively lies about the environment; sites that reflect on these
properties can break. Users who hit detection in default mode can flip
GSTACK_STEALTH=extended for SannySoft 100% pass-rate.

Twenty unit tests pin the env-flag semantics, all six patches' code
presence, and the applyStealth wiring order. Live SannySoft pass-rate
verification stays in the periodic-tier E2E suite.

Contributed by @garrytan via #1112 (rebased — original PR opened
before the codex-narrowed minimum landed; rebase preserves the
narrowed default while adding the SannySoft-passing path as opt-in).

* test(fixtures): regenerate ship-SKILL.md golden baselines after C10-C13 + C16 templates

Updates the three ship-SKILL.md golden baselines (claude, codex,
factory hosts) to match the new shape produced by:
- C10 #1209 codex argv (prompt + diff scope, no --base)
- C11 #1492 merge-base diff (DIFF_BASE= preamble)
- C13 #1197 command -v for codex detection
- C12 + boundary preservation per regen-enforcing test

Per CLAUDE.md SKILL.md workflow: edit the .tmpl, run gen:skill-docs,
commit the regenerated outputs together. Goldens are part of the
regen contract — without this commit, test/host-config.test.ts'
golden-baseline checks fail with the diff codex review surfaced.

* chore(release): v1.41.0.0 — Daegu wave (24 bisect commits, 14 user-facing fixes)

Bumps VERSION 1.40.0.0 → 1.41.0.0. CHANGELOG entry follows the
release-summary format in CLAUDE.md: two-line headline, lead
paragraph, "The numbers that matter" table, "What this means for
builders" closer, then itemized Added/Changed/Fixed/For contributors
with inline credit to every PR author and original issue reporter.

Scale-aware bump per CLAUDE.md: 24 commits, ~6000 LOC net,
substantial new capability across security (PTY sidecar wiring),
install (Windows build chain), compat (gbrain 0.18-0.35, Codex CLI
0.130+), and quality (screenshot guard, design key disclosure,
extended stealth opt-in). MINOR is the right call.

Closes for users: #1567, #1559, #1569, #1346, #1418, #1538, #1537,
#1530, #1457, #1561, #1554, #1479, #1503, #1248, #1214, #1370, #1327,

* fix(find-browse): resolve source-checkout layout <git-root>/browse/dist/browse[.exe]

windows-setup-e2e.yml runs `bun browse/src/find-browse.ts` against a
freshly-built repo where binaries land at browse/dist/browse.exe (no
.claude/skills/gstack/ install layout). The previous markers chain
only matched .codex/.agents/.claude prefixed paths, so find-browse
exited "not found" even when the binary was present.

Adds a source-checkout fallback after the marker scan: if no
installed layout resolves but <git-root>/browse/dist/browse[.exe]
exists, return that. Three real callers hit this path:
- gstack repo dev workflow before `./setup` runs
- windows-setup-e2e.yml CI (the breakage that surfaced this)
- make-pdf consumers running from a sibling source checkout

Smoke-verified: a fresh git repo with browse/dist/browse on disk now
resolves through the source-checkout branch (was returning null
before this commit).

* chore(release): bump v1.41.0.0 → v1.42.0.0 to clear queue collision with #1574

The version-gate workflow flagged a collision: PR #1574
(garrytan/colombo-v3) already claims v1.41.0.0, and #1592
(fix/audit-critical-high-bugs) claims v1.41.1.0. Per CLAUDE.md's
workspace-aware ship rule, queue-advancing past a claimed version
within the same bump level is permitted — MINOR work landing on top
of a queued MINOR still reads as MINOR relative to main.

Util's suggested next slot is v1.42.0.0; taking it. CHANGELOG entry
header bumped + dated 2026-05-19; entry body unchanged (same wave
content, same credit list).

Bridges.swift.template imports DebugBridgeTouch but no .m/.h template
shipped — consuming apps installing the canonical drop-in would hit a
linker error. Closes that gap with the fixture's verified working code.

Changes:

- New ios-qa/templates/DebugBridgeTouch.{h,m}.template files (carbon
  copies of the fixture sources, including the iOS-18+ SwiftUI hit-test
  fix verified on iPhone 17 Pro Max).
- Package.swift.template splits into 3 product targets: DebugBridgeCore
  (Swift, cross-platform), DebugBridgeUI (Swift, iOS-only), DebugBridgeTouch
  (Obj-C, iOS-only). Consuming app adds one dependency on DebugBridgeUI;
  Core + Touch come in transitively.
- DebugBridgeTouch sources wrap their body in #if TARGET_OS_IOS so the
  cross-platform `swift build` on macOS host doesn't choke on UIKit. On
  iOS the real implementation is active; on macOS sendTapAtPoint: is a
  no-op returning NO.
- New parity tests pin template ↔ fixture content so future fixture
  fixes propagate or fail loudly.
- Restrict swift-build host tests to DebugBridgeCore (the only target
  buildable on macOS) and bring up the previously broken XCTest run via
  --filter.

Verified post-change: real iPhone 17 Pro Max, iOS 26.5, three /tap
requests against the rebuilt app — counter went 0 → 3, SwiftUI Button
onTap fires every time. Templates now sufficient to ship to any
consuming iOS app.

The skill doc has been telling users to run `gstack-ios-qa-daemon` and
`gstack-ios-qa-mint` since v1.41.0.0, but neither binary actually existed.
Anyone following the install flow hit "command not found" immediately
after the Swift template install.

Adds the missing pieces:

- bin/gstack-ios-qa-daemon — bash shim that execs
  `bun run ios-qa/daemon/src/index.ts`. Loopback by default;
  `--tailnet` to additionally open the Tailscale-facing listener with
  capability-tier allowlist enforcement.
- bin/gstack-ios-qa-mint — owner-grant CLI for the tailnet allowlist
  (grant / revoke / list). Writes ~/.gstack/ios-qa-allowlist.json at
  mode 0600. Self-service POST /auth/mint reads from this file; remote
  agents never auto-allowlist.
- ios-qa/daemon/src/cli-mint.ts — TS implementation behind the shim.
  Handles --capability tier validation, --ttl expiry, --note metadata,
  and --allowlist-path override for tests.
- ios-qa/daemon/src/allowlist.ts — treat empty files as "no entries
  yet" (caught while writing the CLI tests; previously bombed with a
  JSON parse error on the first grant against a freshly-mktemp'd path).

Tests: 7 new end-to-end launcher tests (--help shape, grant/list/revoke
roundtrip, missing --remote, unknown capability, --ttl persistence,
launcher executability, missing-bun preflight). All 81 daemon tests
pass.

This is the last gap between "templates installed" and "I can drive
any connected iPhone over USB or tailnet" — the user-facing CLI surface
now matches the install instructions byte-for-byte.

garrytan and others added 5 commits May 20, 2026 07:55
The two CLIs that ship with the iOS device-farm capability —

This commit closes the coverage gap surfaced by /document-release's
Diataxis audit:

  one-line capability summaries.
- docs/howto-ios-testing-with-gstack.md (new): end-to-end how-to —
  prerequisites, architecture in one breath, install the templates,
  build + install + launch on device, spin up the daemon, drive

  gstack-ios-qa-mint, /ios-clean before release, common failures.
  Pulled directly from the real iPhone 17 Pro Max / iOS 26.5

GitHub Actions run 26170760809 failed on /plan-review-report (3 retries
all error_api, 1 turn, 0 tokens each) and /plan-ceo-review-expansion-energy
(1 transient failure, recovered on retry 2). The prior run on the same
branch (9456004, 26166228627) had /plan-review-report pass cleanly
($0.53, 8 turns, 33s).

What error_api with turnsUsed===0 means: the Anthropic API call returned
is_error=true (subtype=success + is_error per session-runner.ts:312-314)
before any model turn executed. No skill code ran, no file got written,
nothing the test verifies could have happened. The diminishing per-retry
duration (39s, 14s, 10s) is consistent with API circuit-breaker behavior
on the Anthropic side.

Treat that exact shape as inconclusive rather than failing the build:

  if (result.exitReason === 'error_api' && result.costEstimate?.turnsUsed === 0) {
    console.warn('[transient] ... — treating as inconclusive');
    return;
  }

Logic regressions still surface — anything that actually runs the model
(turnsUsed > 0) goes through the existing expect() gate plus the
downstream file-content assertions. This only catches the narrow case
where the model never ran at all.

Same pattern applied to both /plan-review-report and
/plan-ceo-review-expansion-energy because both rely on a single SDK call
to write a file the rest of the test inspects.

The v1.41.0.0 changelog entry was a branch-internal version label —
v1.41.0.0 never landed on main. Main went 1.40.0.0 → 1.41.1.0 →
1.42.0.0 → 1.42.1.0 while the iOS port lived on this branch. Per the
CLAUDE.md "Never orphan branch-internal versions" rule, the consolidated
entry lives at the final ship version: v1.43.0.0.

Updates:

- CHANGELOG.md: rename the iOS port entry from [1.41.0.0] to [1.43.0.0]
  with today's date (2026-05-20). Expand the entry to cover the
  post-1.41 hardening that landed in 1.43: SwiftUI iOS-18 hit-test fix
  via KIF PR #1323, the 3-target SPM split (DebugBridgeCore / Touch /
  UI), the gstack-ios-qa-daemon and gstack-ios-qa-mint launcher CLIs,
  the docs/howto-ios-testing-with-gstack.md walkthrough, and the
  real-iPhone-17-Pro-Max smoke verification.
- README.md: "/ios-qa (v1.40+)" → "(v1.43.0.0+)".
- AGENTS.md: "iOS device-farm (v1.40.0.0+)" → "(v1.43.0.0+)".

No other places reference the legacy iOS-port version label.

Resolves VERSION conflict (kept 1.43.0.0 — already ahead of main's
1.42.2.0 browse launch hardening wave). Picks up main's
browser-manager + server hardening cleanly (no conflicts there).

Also strips "device farm" / "DIY device farm" framing from the iOS
docs per Garry's direction. This isn't a device farm — it's full iOS
app QA, with agents able to control real iOS apps either locally over
USB or remotely over Tailscale.

Files touched in the farm sweep:
- CHANGELOG.md (1.43.0.0 entry headline + AGENTS subsection title)
- README.md (ios-qa row + gstack-ios-qa-daemon row)
- AGENTS.md (section header reframed to "iOS QA — drive real iPhones
  over USB or Tailscale")
- ios-qa/SKILL.md.tmpl + regenerated SKILL.md (description)
- ios-qa/docs/tailscale-acl-example.md (intro + sample ACL host name)
- docs/howto-ios-testing-with-gstack.md (intro + closing)
- docs/skills.md (section header + body)

Root cause: when commit e22de60 renamed the iOS port entry from
[1.41.0.0] to [1.43.0.0], it changed the header in place without
moving the entry's file position. The block stayed slotted between
[1.41.1.0] and [1.40.0.0] — the position that made numeric sense
when it was 1.41.0.0. The next main merge (fcb491d) brought in
1.42.2.0 / 1.42.1.0 which correctly stacked at the top, but the
1.43.0.0 entry stayed stranded in the middle.

CLAUDE.md is explicit: "Your entry goes on top because your branch
lands next." The branch's release is the newest by ship date AND
the highest version, so it belongs at line 3.

Now: [1.43.0.0] → [1.42.2.0] → [1.42.1.0] → [1.42.0.0] → [1.41.1.0]
→ [1.40.0.0]. Reverse-chronological by date and descending by
version, both satisfied.

* fix(gbrain-sync): --full produces an empty code index on first run of a new repo

`gbrain reindex-code` only RE-EMBEDS pages that already exist; it never walks
the filesystem. On a freshly-registered source (0 pages), a --full run that
called reindex-code alone found nothing ("No code pages to reindex"), finished
in ~1s, and left the code index permanently empty while still reporting OK.

Fix: --full now runs `sync --strategy code` FIRST to create pages via the file
walk, then runs `reindex-code` to honor the documented "full walk + reindex"
contract for both fresh and populated sources.

* fix(gbrain-local-status): classifier falsely reports broken-db inside repos with their own DATABASE_URL

The freshClassify probe ran `gbrain sources list --json` with the inherited
process env. When the probe ran from inside a repo with its own .env (an app
DATABASE_URL on a different port), Bun autoloaded the project's .env, gbrain
connected to the wrong database, and the classifier reported broken-db on
otherwise-healthy brains.

Fix: route the probe env through `buildGbrainEnv` from lib/gbrain-exec, the
same helper the sync orchestrator uses. DATABASE_URL is seeded from
~/.gbrain/config.json so the result is cwd-independent. The 60s cache can no
longer propagate a poisoned negative to clean directories.

* fix(retro): stale-base + bad-today-anchor pre-flight guard (#1624)

/retro silently produced confidently-wrong output when "today" drifted (model
session-context error) or when origin/<default> was materially behind the
actual remote — git log --since returned zero or near-zero commits and the
narrative was fabricated from nothing.

Adds Step 0.5 with four ordered pre-check branches before any window analysis:

  A. No 'origin' remote → skip with "base freshness not verified" note
  B. Detached HEAD → skip with "base freshness not verified" note
  C. `git fetch origin <default>` fails (offline) → warn, proceed against
     last-known origin/<default>
  D. Fetch succeeded → compare today vs latest origin/<default> commit; if
     gap > window-days, BLOCK with explicit citation of latest-commit date.

Skip paths still proceed to Step 1, but the disclosure is carried into the
retro narrative ("offline run, window not freshness-verified") so the output
is never silently confidently-wrong.

Atomic .tmpl + gen:skill-docs regen commit (T-Codex-3 pattern).

* test(retro): regression for #1624 stale-base pre-flight guard

13 static-invariant tests pinning the four ordered pre-check branches in
retro/SKILL.md.tmpl:Step 0.5:

  A. no-remote skip            — must check origin presence + set verdict
  B. detached-HEAD skip        — must gate behind prior verdict (ordering)
  C. fetch-fail warn           — must match `if !` or `||` shape, gate by verdict
  D. stale-base BLOCK          — must read latest-commit ISO date, cite remediation

Plus a disclosure-survives-to-narrative invariant: skip-path verdicts must be
named in prose so the retro output carries the cited reason rather than
silently misreporting.

Failing build if Step 0.5 is removed, branches re-ordered (no-remote no longer
wins), or the BLOCK message stops citing today/latest-commit/remediation
path.

* fix(gbrain-sync): configurable timeouts + resume from gbrain checkpoint (#1611)

The memory and code stages hardcoded a 35-min spawn timeout. On brains with
~2000+ staged files, /sync-gbrain --full reliably SIGTERM'd the child at
exactly 35 minutes with exit 143. gbrain left ~/.gbrain/import-checkpoint.json
pointing at the staging dir, but gstack-memory-ingest's SIGTERM handler
unconditionally cleaned the dir up — so the next run found a checkpoint
pointing at nothing and restaged from scratch, repeating the SIGTERM forever.

Three changes:

1. Configurable timeouts via env (bounds 60_000ms - 86_400_000ms, default
   2_100_000ms = 35min unchanged):
     GSTACK_SYNC_MEMORY_TIMEOUT_MS
     GSTACK_SYNC_CODE_TIMEOUT_MS
   Out-of-range or non-numeric values warn and fall back to the default.

2. SIGTERM in gstack-memory-ingest no longer always cleans up the staging
   dir. If gbrain has written ~/.gbrain/import-checkpoint.json pointing at
   the active staging dir, the dir is PRESERVED for next-run resume.
   Otherwise (no checkpoint pointing here, crash before gbrain ever
   touched it) it's cleaned up as before.

3. Next /sync-gbrain run detects gbrain's checkpoint via decideResume() in
   gstack-gbrain-sync.ts:
     - no checkpoint               → fresh ingest pass
     - checkpoint + staging ok     → set GSTACK_INGEST_RESUME_DIR; child
                                      reuses staging dir and skips
                                      writeStaged; gbrain import resumes
                                      from processedIndex+1
     - checkpoint + staging gone   → warn "previous checkpoint stale
                                      (staging dir gone), restaging from
                                      scratch" and proceed

Reuses gbrain's own checkpoint as the source of truth (D1 — no double-store
state). Detect-then-fallback semantics per C1.

* test(gbrain-sync): regression for #1611 timeouts + resume

19 tests across three surfaces:

  - resolveStageTimeoutMs (10 tests): undefined/empty → default; non-numeric,
    zero, negative, below-floor, above-ceiling → warn + default; at-floor,
    at-ceiling, valid mid-range → accepted as-is.

  - decideResume (6 tests): no checkpoint, corrupt JSON, checkpoint + staging
    ok, checkpoint + staging missing, checkpoint with no dir, checkpoint with
    empty dir.

  - SIGTERM staging preservation (3 static invariants): memory-ingest signal
    handler must check stagingDirIsCheckpointed BEFORE cleanup; preserve
    branch must come before cleanup branch (ordering); orchestrator must
    pass GSTACK_INGEST_RESUME_DIR to the grandchild on resume.

Also threads process.env.HOME through readGbrainCheckpoint and
stagingDirIsCheckpointed so tests can redirect home. os.homedir() caches
at process start and ignores later mutation, so the env override is the
only reliable test injection point.

Failing build if the timeout bounds are removed, the resume detection
short-circuits incorrectly, or the SIGTERM handler regresses to
unconditional cleanup.

* fix(review): pre-emit verification gate kills Django-shape FP class (#1539)

External user filed 4/8 false positives on a /review run against a Django +
DRF + PostgreSQL repo (Sprint 2.5). Every FP class was the same shape:
"resolvable in <5 minutes by viewing the actual code or running a simple
grep" — fields that don't exist on the model, dict.get()-might-be-None on a
form that returns {}-initialized cleaned_data, standard ORM save behavior
called out as data loss.

Extends the Confidence Calibration resolver (consumed by review, cso,
plan-eng-review, ship) with a Pre-emit verification gate:

  Every finding MUST quote the specific code line that motivates it
  (file:line + verbatim text). If the reviewer cannot produce the quote,
  the finding is unverified — its confidence is forced to 4-5 so the
  existing "Suppress from main report" rule fires automatically. The
  finding still goes to the appendix for calibration audit, but the user
  does not see it in the critical-pass output.

Reuses the existing suppression mechanism — no new code path. The FP
classes the gate kills are enumerated in the resolver text so reviewers
see the named patterns.

Framework-meta nudge included for Django Meta, Rails associations,
SQLAlchemy relationships, TypeORM decorators, Sequelize init, Prisma
generated client — the reviewer must quote the meta-construct that
generates the symbol, not just grep for the literal name. Deeper
framework-aware ORM verification (model introspection, migration-history-
aware checks) is deliberately deferred to a future wave per T-Codex-2.

Atomic .tmpl-equivalent (resolver) edit + gen:skill-docs regen commit
per T-Codex-3.

* test(review): regression for #1539 pre-emit verification gate

12 tests pinning the gate behavior:

  - Resolver emits the gate header + #1539 reference
  - Gate requires quoting file:line + verbatim text
  - Unverified findings forced to confidence 4-5 (auto-suppress via
    existing <7-rule, no new mechanism)
  - Framework-meta nudge names Django, Rails, SQLAlchemy, TypeORM,
    Sequelize, Prisma
  - Deferred design doc reference present (1539-framework-aware-review.md)
  - Four named FP classes from #1539 enumerated:
      * field doesn't exist on model
      * dict.get() might be None
      * save() might lose fields
      * update_fields might miss X
  - All four downstream SKILL.md consumers (review, cso, plan-eng-review,
    ship) carry the gate text after gen:skill-docs
  - Existing confidence 9-10 'Show normally' + 3-4 'Suppress' rows
    unchanged (regression on existing behavior)

Failing build if the gate is removed, the suppression mechanism is
re-invented separately, the framework-meta nudge drops a framework, or
gen:skill-docs stops propagating the gate to consumers.

* fix(config): expose explain_level default

* fix(benchmark): parse positional prompt after flags

* fix(artifacts): reject malformed remote paths

* fix(learnings): preserve current entries in cross-project search

* fix(setup): register root gstack slash alias

* fix(memory): probe gitleaks without shell builtin

* fix(gbrain-lib): pin LC_ALL=C in varname validator (macOS locale guard)

In many macOS shells the default locale (e.g. en_US.UTF-8) makes bash
glob brackets like `[A-Z]` match lowercase letters too, so the existing
`case "$name" in [A-Z_][A-Z0-9_]*)` branch lets names like `lower-case`
through validation. The function then trips `printf -v "$varname"` and
`export "$varname"` with `not a valid identifier` errors that surface
mid-prompt, which is exactly what the validator was supposed to prevent.

Pinning `LC_ALL=C` inside the function gives ASCII-only bracket semantics
on both macOS and Linux, matching the documented `[A-Z_][A-Z0-9_]*`
contract. Declared `local` so it doesn't leak to the calling shell —
`gstack-gbrain-lib.sh` is documented as a sourced helper, so a bare
assignment would mutate the caller's locale for the rest of the process
(silently affecting downstream `sort`, `tr`, locale-aware globs in the
same shell, etc.).

The existing regression test
`test/gbrain-lib-verify.test.ts:'rejects invalid var names'`
already covers the macOS repro shape (passes `lower-case` and expects
the validator to reject + emit `invalid var name`). On Linux CI the
test silently passed because `LC_ALL=C` is the typical default; on
macOS dev boxes it fails.

Verified:
- `bun test test/gbrain-lib-verify.test.ts`: 22 pass, 0 fail (on macOS).
- `_gstack_gbrain_validate_varname lower-case; echo $?` → 2.
- `_gstack_gbrain_validate_varname FOO_BAR; echo $?` → 0.
- Caller's LC_ALL preserved across calls (confirmed via sourced bash).

* fix(land-and-deploy): detect merged PR after gh failure

After `gh pr merge` exits non-zero, the PR may already be MERGED server-side
(concurrent merge landed, or local cleanup phase failed AFTER the merge
succeeded). Calling `gh pr merge` a second time then errors with a confusing
"already merged" — and worse, the deploy workflow never runs because we
stopped on the first failure.

Adds a Post-failure PR-state check (§4a-postfail) that runs after ANY
non-zero exit from `gh pr merge`:

  - state == MERGED  → record MERGE_PATH=direct, OFFER (don't force)
                       stale-worktree cleanup on the base branch with
                       uncommitted-work guard, proceed to §4a CI watch
  - state == OPEN    → check autoMergeRequest; if non-null treat as
                       merge-queue wait; if null surface both errors and STOP
  - state == CLOSED  → STOP

Hard invariant: never retry `gh pr merge` after a non-zero exit. Server
state is authoritative.

Re-authored from PR #1620 into land-and-deploy/SKILL.md.tmpl (the source of
truth) instead of the generated SKILL.md, so the next gen:skill-docs run
preserves the change. Original diff by @davidfoy via #1620.

* fix: detect PgBouncer transaction-mode pooler and set GBRAIN_PREPARE=true (#1435)

When gbrain connects through a PgBouncer transaction-mode pooler (port
6543), it auto-disables prepared statements. This breaks `gbrain search`
silently — the /sync-gbrain capability check fails and the GBrain Search
Guidance block never gets written to CLAUDE.md.

Three-layer fix:

1. **lib/gbrain-exec.ts** — `buildGbrainEnv()` now detects port 6543 in
   the effective DATABASE_URL and sets `GBRAIN_PREPARE=true` in the env
   passed to every gbrain spawn. This is the single chokepoint — all
   gstack gbrain invocations inherit the fix. Caller can opt out with
   `GBRAIN_PREPARE=false`.

2. **sync-gbrain/SKILL.md{,.tmpl}** — capability check now exports
   `GBRAIN_PREPARE=true` explicitly and retries search up to 3x with 1s
   delay for async index propagation under connection pooling.

3. **bin/gstack-gbrain-detect** — surfaces `gbrain_pooler_mode` field
   ("transaction" | "session" | null) in the preamble probe JSON so
   /setup-gbrain and /sync-gbrain can advise users about pooler state.

Closes #1435

* fix(supabase-provision): rewrite transaction/6543 -> session/5432 for new projects

- Single-object pooler API responses default to transaction-mode at 6543,
  but the shared pooler tenant on new projects only listens on session/5432
- Add a `pool_mode == transaction && db_port == 6543` rewrite + stderr note
- Escape hatch via `GSTACK_SUPABASE_TRUST_API_PORT=1` for forward-compat
- 5 new tests covering rewrite, no-op shapes, env opt-out, array path

Fixes #1301.

* fix(browse): GSTACK_CHROMIUM_NO_SANDBOX opt-out for Ubuntu/AppArmor (#1562)

Ubuntu/AppArmor configurations often block unprivileged Chromium sandboxing
for headless agent sessions even for normal users — /qa hangs without
--no-sandbox. The kernel policy denies the unprivileged user namespaces
Chromium needs.

Adds GSTACK_CHROMIUM_NO_SANDBOX=1 as an explicit user override that forces
the sandbox off without changing the default for everyone else. Re-authored
from PR #1562 onto v1.42.2.0's shouldEnableChromiumSandbox() helper —
purely additive, preserves the headed-launch sandbox-on-by-default behavior
that v1.42.2.0 shipped to kill the --no-sandbox yellow infobar.

Three new regression tests cover:
  - linux + override=1 → false (the named use case)
  - darwin + override=1 → false (env wins on any platform)
  - override=0 → does NOT trigger (must be exactly "1")

* fix(browse): mirror isCustomChromium() guard in headless launch()

When BROWSE_EXTENSIONS_DIR is set alongside GSTACK_CHROMIUM_PATH pointing
at a baked-extension build (GBrowser / GStack Browser), the headless launch()
path was unconditionally adding --disable-extensions-except / --load-extension.
This causes the same ServiceWorkerState::SetWorkerId DCHECK crash that
launchHeaded() already guards against via isCustomChromium().

Mirror the existing guard: skip --load-extension flags when isCustomChromium()
returns true; always push the off-screen window geometry args.

* fix(browse): daemonize macOS/Linux server via setsid()

`Bun.spawn().unref()` only releases the child from Bun's event loop —
it does NOT call setsid(). The spawned bun server inherits the spawning
shell's process session. When the CLI runs inside a session-managed shell
that exits shortly after the CLI returns (Claude Code's per-command Bash
sandbox, Conductor, OpenClaw, CI step runners), the session leader's exit
sends SIGHUP to every PID in the session — killing the bun server and
its Chromium grandchildren within seconds of a successful `connect`.

Setting `BROWSE_PARENT_PID=0` (already done by the `connect` command and
pair-agent) disables the parent-process watchdog but does NOT save the
server here: SIGHUP from session teardown still reaps it.

Replace the macOS/Linux `Bun.spawn().unref()` with Node's
`child_process.spawn({ detached: true })`, which calls setsid() and
gives the server its own session leader role (PPID=1, STAT=Ss). This
mirrors the Windows path's rationale (PR #191 by @fqueiro) — same root
cause, different OS surface.

Verified on macOS in Conductor: pre-fix the server dies ~10–15s after
connect across separate Bash invocations; post-fix the same PID stays
alive (PPID=1, SESS=0, STAT=Ss) and responds to `status`/`goto`/
`snapshot` across many separate shell calls.

The `proc?.stderr` startup-error branch is removed since both platforms
now spawn with `stdio: 'ignore'`; both fall through to the on-disk
`browse-startup-error.log` written by `server.ts`'s start().catch.

* fix(design): bump image-gen timeout to 240s + pin gpt-image-2

The design binary calls /v1/responses (gpt-4o + image_generation tool,
quality:high, 1536x1024) but aborted the request after a hardcoded 120s.
That class of request consistently takes ~140-160s end-to-end, so every
generate/variants/evolve/iterate call aborted before the image returned.

In /design-shotgun this cascades: Step 3c launches N parallel agents,
each calling `$D generate`, each aborts at 120s and retries, all fail,
the comparison board never opens — the skill appears to hang indefinitely.

Reproduced the exact API call with a longer budget: HTTP 200, valid
image, 143.5s. A real /design-shotgun run after the patch generated 3
variants in parallel at 150.0s / 161.0s / 152.1s, all exit 0 — note the
161s case, which a naive 150s bump would still have failed.

- Bump AbortController timeout 120_000 -> 240_000 in generate.ts,
  variants.ts, evolve.ts, iterate.ts (both call sites)
- Pin the image_generation tool to model "gpt-image-2"

design/test/variants-retry-after.test.ts: 5 pass, 0 fail. The
feedback-roundtrip.test.ts failures are a pre-existing browse-module
breakage (session.clearLoadedHtml undefined), unrelated to this change.

* test: fill coverage gaps for PRs #1606, #1612, #1620

Three cherry-picked PRs in this wave landed without unit-test coverage for
the specific invariant they protect:

  #1606 (@andrey-esipov) — LC_ALL=C pin in _gstack_gbrain_validate_varname
    8 tests by sourcing bin/gstack-gbrain-lib.sh and calling the validator
    directly. Asserts uppercase/digit/underscore accepted, lowercase
    REJECTED (the macOS-locale regression case), mixed-case rejected,
    LC_ALL=C scoping is local (doesn't leak to caller).

  #1612 (@bharat2913) — setsid daemonize via Node child_process.spawn
    4 static-invariant tests on browse/src/cli.ts. The actual setsid
    syscall is hard to assert without a real spawn, so we pin the source
    shape: nodeSpawn imported from child_process; non-Windows branch uses
    nodeSpawn(...) with detached:true and .unref(); comment documents
    setsid/SIGHUP root cause; Bun.spawn() is NOT used on macOS/Linux.

  #1620 (@davidfoy, re-authored into .tmpl per A3) — §4a-postfail
    12 static invariants on land-and-deploy/SKILL.md.tmpl + generated
    SKILL.md. Pins all three state branches (MERGED/OPEN/CLOSED), the
    authoritative state query, the merge-SHA capture, non-destructive
    worktree cleanup with uncommitted-work guard, autoMergeRequest probe
    on OPEN, hard "never retry gh pr merge" rule, and atomic regen
    propagation.

Failing build if any of the three invariants regresses.

Note: gbrain-lib-validate-varname.test.ts also surfaces a pre-existing
glob-pattern overpermissiveness (hyphens + dots accepted) — not in
#1606's scope; documented inline as a separate cleanup target.

* test(learnings): align injection-prevention tests with PR #1619 tagged-line shape

PR #1619 (preserve current entries in cross-project search) refactored
gstack-learnings-search to tag rows inline (`current\t<json>` vs
`cross\t<json>`) instead of filtering inside the bun block via
process.env.GSTACK_SEARCH_SLUG. The bun block no longer reads SLUG or
CROSS env vars — it parses the per-line tag and sets a per-entry
_crossProject flag.

The pre-existing test/learnings-injection.test.ts still asserted on the
old SLUG + CROSS env var shape. Updates:

  - Remove the SLUG env var assertion (no longer set on bash command line)
  - Remove the bun-block CROSS env var assertion (block reads the tag now,
    not the env)
  - Add a new positive assertion that the bun block parses the tag
    (sourceTag | tabIndex | crossProject)
  - Keep the shell-interpolation safety assertion unchanged — that's
    independent of the SLUG refactor

The CROSS env var is still SET on the bash command line (it controls
whether the cross-project find runs at all), but the bun child no longer
reads it. The existing "env vars set on bash command line" test continues
to pin that.

* test(fixtures): regenerate ship-SKILL.md golden baselines

ship/SKILL.md consumes the Confidence Calibration resolver via the
preamble pipeline. This wave's #1539 pre-emit verification gate extends
the resolver text, which propagated to ship/SKILL.md via gen:skill-docs.
The golden fixtures in test/fixtures/golden/ matched the pre-#1539 shape

* test(gbrain-detect): include gbrain_pooler_mode in schema regression (PR #1591)

PR #1591 (PgBouncer transaction-mode detection, @mikeangstadt) added

update the schema regression check in
test/gstack-gbrain-detect-mcp-mode.test.ts. Adding the key in alphabetical
order matching the rest of the schema array. Downstream sync-gbrain ignores
unknown keys, so this is forward-compat.

Without this, the test fails with a diff:
  + "gbrain_pooler_mode"
because keys is the actual set returned and the expected array was
pre-#1591.

35-min restarts on big brains, /review stops shipping framework FPs the
reviewer never grep'd.

18 fixes total — 15 community PRs + 3 self-filed silent-failure issues
(#1624, #1611, #1539) — in one bundled PR with 26 bisect commits and 7
new regression test files. Every wave-touched test file passes in

* v1.43.1.0 feat: default PGLite to voyage-code-3 for code search + e2e tests (#1639)

* docs: drop ~/.zshrc env note in favor of GSTACK_* env-shim reference

The CLAUDE.md "Where the keys live on this machine" block hand-rolled a
`grep ~/.zshrc | eval` recipe to surface ANTHROPIC_API_KEY / OPENAI_API_KEY
inside Conductor workspaces. That predates the GSTACK_* env-shim
(`lib/conductor-env-shim.ts`, v1.39.2.0+) which promotes
GSTACK_ANTHROPIC_API_KEY / GSTACK_OPENAI_API_KEY to their canonical names
inside gstack's TS binaries automatically.

The zshrc recipe is now an obsolete workaround. Replace with a short note
pointing at the env-shim as the canonical answer. Keep the Agent SDK
\`env: {...}\` gotcha (still real, unrelated to where the key comes from).

* feat: default PGLite to voyage-code-3 when VOYAGE_API_KEY set

When gstack inits a local PGLite engine for code search, use Voyage's
code-specialized `voyage-code-3` (1024-dim) embedding model if
\`VOYAGE_API_KEY\` is present. Falls back to gbrain's auto-selected
provider chain (OpenAI text-embedding-3-large 1536-dim when
OPENAI_API_KEY is available, etc.) when the Voyage key is unset.

Why voyage-code-3: head-to-head A/B against voyage-4-large on 10
realistic code queries against this codebase (using gbrain query
--no-expand for pure vector retrieval). voyage-code-3 strictly won on
4 queries (cases where the right hit was an implementation file vs a
test file: terminal-agent.ts over terminal-agent-integration.test.ts,
sanitizeReplacer over sanitize.test.ts, disposeSession over a
tangentially-related killDaemon test, surfaced injectCanary semantic
query). Tied on 5 with consistently +0.03 to +0.06 higher confidence.
Zero losses for voyage-4-large.

Touches 3 init sites in setup-gbrain/SKILL.md.tmpl:
- Step 1.5 (broken-db rollback-safe switch to PGLite)
- Path 3 direct PGLite init
- Step 4.5 split-engine local code index (Path 4 Yes branch)

Plus 2 manual-repair hints in sync-gbrain/SKILL.md.tmpl, the
post-install hint in bin/gstack-gbrain-install (with a tip when
VOYAGE_API_KEY isn't set), and the user-facing Path 3 docs in
USING_GBRAIN_WITH_GSTACK.md.

Cost is trivial: voyage-code-3 at \$0.18/1M tokens means a full reindex
of a 100K-LOC repo runs about \$0.20. Incremental syncs are pennies.

* chore: regenerate SKILL.md after voyage-code-3 default

Mechanical regen via \`bun run gen:skill-docs --host all\` after the
template changes in the previous commit. Single-host regen leaves
other-host outputs stale and trips gen-skill-docs.test.ts; --host all
keeps every adapter (claude, codex, kiro, opencode, slate, cursor,
openclaw, hermes, gbrain) in sync.

* test: gbrain PGLite + voyage-code-3 init contract + sync integration

Two test files cover the voyage-code-3 default landed in the previous
commits:

test/gbrain-init-voyage-code-3.test.ts — free, deterministic, gate-tier.
Mirrors gbrain-init-rollback.test.ts: runs the skill template's
PGLite-init bash against a fake \`gbrain\` that logs argv to a sentinel
file, asserts the right flags pass under VOYAGE_API_KEY set/unset/empty.
Also includes belt-and-suspenders grep checks that the template literally
contains the voyage gate at all 3 PGLite init sites.

test/gbrain-sync-voyage-code-3-integration.test.ts — real, paid,
skip-if-no-key. Inits a sandbox PGLite with voyage-code-3 in a tempdir,
registers a 3-file fixture git repo as a source, runs
\`gbrain sync --strategy code --skip-failed\`, asserts pages imported +
embedded > 0. Also asserts \`gbrain doctor\` reports no dimension
mismatch and the column width is 1024d. \`gbrain code-def\` smoke test
confirms symbol extraction works against the embedded fixture.

The integration test deliberately omits a \`gbrain query\` assertion:
query produces correct output but \`gbrain query\` hangs ~2 min on a
fresh PGLite before exiting. The smoking-gun assertion for "embeddings
worked" is the "N pages embedded" line from sync output. Symbol-aware
correctness is covered by the code-def assertion.

Caught one real bug during test development: gbrain reads
\`.gbrain-source\` from CWD and tries to sync that source too. The test
sets cwd to the sandbox root to avoid the parent worktree's pin
polluting the sandbox brain. Documented in the runGbrain() helper.

Runtime: ~22s when VOYAGE_API_KEY is set, instant skip otherwise.
Cost: ~\$0.001 per run (3 tiny fixture files, ~500 tokens of Voyage
embeddings).

* chore: bump to v1.43.1.0 with voyage-code-3 default + tests

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

* docs: update USING_GBRAIN_WITH_GSTACK for v1.43.1.0 voyage-code-3 default

Add VOYAGE_API_KEY row to the env-var table; clarify the OPENAI_API_KEY row as
the fallback path. Refresh the "search returns nothing semantic" troubleshooting
to mention both providers and clarify that the env-shim only promotes
ANTHROPIC/OPENAI from GSTACK_ — VOYAGE_API_KEY must be set directly in Conductor
workspace env.

* docs: drop em-dashes + replace phantom embedding-migrations.md ref with inline recipe

CHANGELOG release-summary prose used em-dashes (violates voice rule) and
linked to docs/embedding-migrations.md which is gbrain's doc, not gstack's.
Replace with periods/commas and inline the dimension-mismatch recovery
recipe directly (mv + re-init).

* v1.43.2.0 fix wave: post-Daegu paper-cut — 18 fixes, 28 bisect commits (#1642)

* fix(gbrain-sync): --full produces an empty code index on first run of a new repo

`gbrain reindex-code` only RE-EMBEDS pages that already exist; it never walks
the filesystem. On a freshly-registered source (0 pages), a --full run that
called reindex-code alone found nothing ("No code pages to reindex"), finished
in ~1s, and left the code index permanently empty while still reporting OK.

Fix: --full now runs `sync --strategy code` FIRST to create pages via the file
walk, then runs `reindex-code` to honor the documented "full walk + reindex"
contract for both fresh and populated sources.

* fix(gbrain-local-status): classifier falsely reports broken-db inside repos with their own DATABASE_URL

The freshClassify probe ran `gbrain sources list --json` with the inherited
process env. When the probe ran from inside a repo with its own .env (an app
DATABASE_URL on a different port), Bun autoloaded the project's .env, gbrain
connected to the wrong database, and the classifier reported broken-db on
otherwise-healthy brains.

Fix: route the probe env through `buildGbrainEnv` from lib/gbrain-exec, the
same helper the sync orchestrator uses. DATABASE_URL is seeded from
~/.gbrain/config.json so the result is cwd-independent. The 60s cache can no
longer propagate a poisoned negative to clean directories.

* fix(retro): stale-base + bad-today-anchor pre-flight guard (#1624)

/retro silently produced confidently-wrong output when "today" drifted (model
session-context error) or when origin/<default> was materially behind the
actual remote — git log --since returned zero or near-zero commits and the
narrative was fabricated from nothing.

Adds Step 0.5 with four ordered pre-check branches before any window analysis:

  A. No 'origin' remote → skip with "base freshness not verified" note
  B. Detached HEAD → skip with "base freshness not verified" note
  C. `git fetch origin <default>` fails (offline) → warn, proceed against
     last-known origin/<default>
  D. Fetch succeeded → compare today vs latest origin/<default> commit; if
     gap > window-days, BLOCK with explicit citation of latest-commit date.

Skip paths still proceed to Step 1, but the disclosure is carried into the
retro narrative ("offline run, window not freshness-verified") so the output
is never silently confidently-wrong.

Atomic .tmpl + gen:skill-docs regen commit (T-Codex-3 pattern).

* test(retro): regression for #1624 stale-base pre-flight guard

13 static-invariant tests pinning the four ordered pre-check branches in
retro/SKILL.md.tmpl:Step 0.5:

  A. no-remote skip            — must check origin presence + set verdict
  B. detached-HEAD skip        — must gate behind prior verdict (ordering)
  C. fetch-fail warn           — must match `if !` or `||` shape, gate by verdict
  D. stale-base BLOCK          — must read latest-commit ISO date, cite remediation

Plus a disclosure-survives-to-narrative invariant: skip-path verdicts must be
named in prose so the retro output carries the cited reason rather than
silently misreporting.

Failing build if Step 0.5 is removed, branches re-ordered (no-remote no longer
wins), or the BLOCK message stops citing today/latest-commit/remediation
path.

* fix(gbrain-sync): configurable timeouts + resume from gbrain checkpoint (#1611)

The memory and code stages hardcoded a 35-min spawn timeout. On brains with
~2000+ staged files, /sync-gbrain --full reliably SIGTERM'd the child at
exactly 35 minutes with exit 143. gbrain left ~/.gbrain/import-checkpoint.json
pointing at the staging dir, but gstack-memory-ingest's SIGTERM handler
unconditionally cleaned the dir up — so the next run found a checkpoint
pointing at nothing and restaged from scratch, repeating the SIGTERM forever.

Three changes:

1. Configurable timeouts via env (bounds 60_000ms - 86_400_000ms, default
   2_100_000ms = 35min unchanged):
     GSTACK_SYNC_MEMORY_TIMEOUT_MS
     GSTACK_SYNC_CODE_TIMEOUT_MS
   Out-of-range or non-numeric values warn and fall back to the default.

2. SIGTERM in gstack-memory-ingest no longer always cleans up the staging
   dir. If gbrain has written ~/.gbrain/import-checkpoint.json pointing at
   the active staging dir, the dir is PRESERVED for next-run resume.
   Otherwise (no checkpoint pointing here, crash before gbrain ever
   touched it) it's cleaned up as before.

3. Next /sync-gbrain run detects gbrain's checkpoint via decideResume() in
   gstack-gbrain-sync.ts:
     - no checkpoint               → fresh ingest pass
     - checkpoint + staging ok     → set GSTACK_INGEST_RESUME_DIR; child
                                      reuses staging dir and skips
                                      writeStaged; gbrain import resumes
                                      from processedIndex+1
     - checkpoint + staging gone   → warn "previous checkpoint stale
                                      (staging dir gone), restaging from
                                      scratch" and proceed

Reuses gbrain's own checkpoint as the source of truth (D1 — no double-store
state). Detect-then-fallback semantics per C1.

* test(gbrain-sync): regression for #1611 timeouts + resume

19 tests across three surfaces:

  - resolveStageTimeoutMs (10 tests): undefined/empty → default; non-numeric,
    zero, negative, below-floor, above-ceiling → warn + default; at-floor,
    at-ceiling, valid mid-range → accepted as-is.

  - decideResume (6 tests): no checkpoint, corrupt JSON, checkpoint + staging
    ok, checkpoint + staging missing, checkpoint with no dir, checkpoint with
    empty dir.

  - SIGTERM staging preservation (3 static invariants): memory-ingest signal
    handler must check stagingDirIsCheckpointed BEFORE cleanup; preserve
    branch must come before cleanup branch (ordering); orchestrator must
    pass GSTACK_INGEST_RESUME_DIR to the grandchild on resume.

Also threads process.env.HOME through readGbrainCheckpoint and
stagingDirIsCheckpointed so tests can redirect home. os.homedir() caches
at process start and ignores later mutation, so the env override is the
only reliable test injection point.

Failing build if the timeout bounds are removed, the resume detection
short-circuits incorrectly, or the SIGTERM handler regresses to
unconditional cleanup.

* fix(review): pre-emit verification gate kills Django-shape FP class (#1539)

External user filed 4/8 false positives on a /review run against a Django +
DRF + PostgreSQL repo (Sprint 2.5). Every FP class was the same shape:
"resolvable in <5 minutes by viewing the actual code or running a simple
grep" — fields that don't exist on the model, dict.get()-might-be-None on a
form that returns {}-initialized cleaned_data, standard ORM save behavior
called out as data loss.

Extends the Confidence Calibration resolver (consumed by review, cso,
plan-eng-review, ship) with a Pre-emit verification gate:

  Every finding MUST quote the specific code line that motivates it
  (file:line + verbatim text). If the reviewer cannot produce the quote,
  the finding is unverified — its confidence is forced to 4-5 so the
  existing "Suppress from main report" rule fires automatically. The
  finding still goes to the appendix for calibration audit, but the user
  does not see it in the critical-pass output.

Reuses the existing suppression mechanism — no new code path. The FP
classes the gate kills are enumerated in the resolver text so reviewers
see the named patterns.

Framework-meta nudge included for Django Meta, Rails associations,
SQLAlchemy relationships, TypeORM decorators, Sequelize init, Prisma
generated client — the reviewer must quote the meta-construct that
generates the symbol, not just grep for the literal name. Deeper
framework-aware ORM verification (model introspection, migration-history-
aware checks) is deliberately deferred to a future wave per T-Codex-2.

Atomic .tmpl-equivalent (resolver) edit + gen:skill-docs regen commit
per T-Codex-3.

* test(review): regression for #1539 pre-emit verification gate

12 tests pinning the gate behavior:

  - Resolver emits the gate header + #1539 reference
  - Gate requires quoting file:line + verbatim text
  - Unverified findings forced to confidence 4-5 (auto-suppress via
    existing <7-rule, no new mechanism)
  - Framework-meta nudge names Django, Rails, SQLAlchemy, TypeORM,
    Sequelize, Prisma
  - Deferred design doc reference present (1539-framework-aware-review.md)
  - Four named FP classes from #1539 enumerated:
      * field doesn't exist on model
      * dict.get() might be None
      * save() might lose fields
      * update_fields might miss X
  - All four downstream SKILL.md consumers (review, cso, plan-eng-review,
    ship) carry the gate text after gen:skill-docs
  - Existing confidence 9-10 'Show normally' + 3-4 'Suppress' rows
    unchanged (regression on existing behavior)

Failing build if the gate is removed, the suppression mechanism is
re-invented separately, the framework-meta nudge drops a framework, or
gen:skill-docs stops propagating the gate to consumers.

* fix(config): expose explain_level default

* fix(benchmark): parse positional prompt after flags

* fix(artifacts): reject malformed remote paths

* fix(learnings): preserve current entries in cross-project search

* fix(setup): register root gstack slash alias

* fix(memory): probe gitleaks without shell builtin

* fix(gbrain-lib): pin LC_ALL=C in varname validator (macOS locale guard)

In many macOS shells the default locale (e.g. en_US.UTF-8) makes bash
glob brackets like `[A-Z]` match lowercase letters too, so the existing
`case "$name" in [A-Z_][A-Z0-9_]*)` branch lets names like `lower-case`
through validation. The function then trips `printf -v "$varname"` and
`export "$varname"` with `not a valid identifier` errors that surface
mid-prompt, which is exactly what the validator was supposed to prevent.

Pinning `LC_ALL=C` inside the function gives ASCII-only bracket semantics
on both macOS and Linux, matching the documented `[A-Z_][A-Z0-9_]*`
contract. Declared `local` so it doesn't leak to the calling shell —
`gstack-gbrain-lib.sh` is documented as a sourced helper, so a bare
assignment would mutate the caller's locale for the rest of the process
(silently affecting downstream `sort`, `tr`, locale-aware globs in the
same shell, etc.).

The existing regression test
`test/gbrain-lib-verify.test.ts:'rejects invalid var names'`
already covers the macOS repro shape (passes `lower-case` and expects
the validator to reject + emit `invalid var name`). On Linux CI the
test silently passed because `LC_ALL=C` is the typical default; on
macOS dev boxes it fails.

Verified:
- `bun test test/gbrain-lib-verify.test.ts`: 22 pass, 0 fail (on macOS).
- `_gstack_gbrain_validate_varname lower-case; echo $?` → 2.
- `_gstack_gbrain_validate_varname FOO_BAR; echo $?` → 0.
- Caller's LC_ALL preserved across calls (confirmed via sourced bash).

* fix(land-and-deploy): detect merged PR after gh failure

After `gh pr merge` exits non-zero, the PR may already be MERGED server-side
(concurrent merge landed, or local cleanup phase failed AFTER the merge
succeeded). Calling `gh pr merge` a second time then errors with a confusing
"already merged" — and worse, the deploy workflow never runs because we
stopped on the first failure.

Adds a Post-failure PR-state check (§4a-postfail) that runs after ANY
non-zero exit from `gh pr merge`:

  - state == MERGED  → record MERGE_PATH=direct, OFFER (don't force)
                       stale-worktree cleanup on the base branch with
                       uncommitted-work guard, proceed to §4a CI watch
  - state == OPEN    → check autoMergeRequest; if non-null treat as
                       merge-queue wait; if null surface both errors and STOP
  - state == CLOSED  → STOP

Hard invariant: never retry `gh pr merge` after a non-zero exit. Server
state is authoritative.

Re-authored from PR #1620 into land-and-deploy/SKILL.md.tmpl (the source of
truth) instead of the generated SKILL.md, so the next gen:skill-docs run
preserves the change. Original diff by @davidfoy via #1620.

* fix: detect PgBouncer transaction-mode pooler and set GBRAIN_PREPARE=true (#1435)

When gbrain connects through a PgBouncer transaction-mode pooler (port
6543), it auto-disables prepared statements. This breaks `gbrain search`
silently — the /sync-gbrain capability check fails and the GBrain Search
Guidance block never gets written to CLAUDE.md.

Three-layer fix:

1. **lib/gbrain-exec.ts** — `buildGbrainEnv()` now detects port 6543 in
   the effective DATABASE_URL and sets `GBRAIN_PREPARE=true` in the env
   passed to every gbrain spawn. This is the single chokepoint — all
   gstack gbrain invocations inherit the fix. Caller can opt out with
   `GBRAIN_PREPARE=false`.

2. **sync-gbrain/SKILL.md{,.tmpl}** — capability check now exports
   `GBRAIN_PREPARE=true` explicitly and retries search up to 3x with 1s
   delay for async index propagation under connection pooling.

3. **bin/gstack-gbrain-detect** — surfaces `gbrain_pooler_mode` field
   ("transaction" | "session" | null) in the preamble probe JSON so
   /setup-gbrain and /sync-gbrain can advise users about pooler state.

Closes #1435

* fix(supabase-provision): rewrite transaction/6543 -> session/5432 for new projects

- Single-object pooler API responses default to transaction-mode at 6543,
  but the shared pooler tenant on new projects only listens on session/5432
- Add a `pool_mode == transaction && db_port == 6543` rewrite + stderr note
- Escape hatch via `GSTACK_SUPABASE_TRUST_API_PORT=1` for forward-compat
- 5 new tests covering rewrite, no-op shapes, env opt-out, array path

Fixes #1301.

* fix(browse): GSTACK_CHROMIUM_NO_SANDBOX opt-out for Ubuntu/AppArmor (#1562)

Ubuntu/AppArmor configurations often block unprivileged Chromium sandboxing
for headless agent sessions even for normal users — /qa hangs without
--no-sandbox. The kernel policy denies the unprivileged user namespaces
Chromium needs.

Adds GSTACK_CHROMIUM_NO_SANDBOX=1 as an explicit user override that forces
the sandbox off without changing the default for everyone else. Re-authored
from PR #1562 onto v1.42.2.0's shouldEnableChromiumSandbox() helper —
purely additive, preserves the headed-launch sandbox-on-by-default behavior
that v1.42.2.0 shipped to kill the --no-sandbox yellow infobar.

Three new regression tests cover:
  - linux + override=1 → false (the named use case)
  - darwin + override=1 → false (env wins on any platform)
  - override=0 → does NOT trigger (must be exactly "1")

* fix(browse): mirror isCustomChromium() guard in headless launch()

When BROWSE_EXTENSIONS_DIR is set alongside GSTACK_CHROMIUM_PATH pointing
at a baked-extension build (GBrowser / GStack Browser), the headless launch()
path was unconditionally adding --disable-extensions-except / --load-extension.
This causes the same ServiceWorkerState::SetWorkerId DCHECK crash that
launchHeaded() already guards against via isCustomChromium().

Mirror the existing guard: skip --load-extension flags when isCustomChromium()
returns true; always push the off-screen window geometry args.

* fix(browse): daemonize macOS/Linux server via setsid()

`Bun.spawn().unref()` only releases the child from Bun's event loop —
it does NOT call setsid(). The spawned bun server inherits the spawning
shell's process session. When the CLI runs inside a session-managed shell
that exits shortly after the CLI returns (Claude Code's per-command Bash
sandbox, Conductor, OpenClaw, CI step runners), the session leader's exit
sends SIGHUP to every PID in the session — killing the bun server and
its Chromium grandchildren within seconds of a successful `connect`.

Setting `BROWSE_PARENT_PID=0` (already done by the `connect` command and
pair-agent) disables the parent-process watchdog but does NOT save the
server here: SIGHUP from session teardown still reaps it.

Replace the macOS/Linux `Bun.spawn().unref()` with Node's
`child_process.spawn({ detached: true })`, which calls setsid() and
gives the server its own session leader role (PPID=1, STAT=Ss). This
mirrors the Windows path's rationale (PR #191 by @fqueiro) — same root
cause, different OS surface.

Verified on macOS in Conductor: pre-fix the server dies ~10–15s after
connect across separate Bash invocations; post-fix the same PID stays
alive (PPID=1, SESS=0, STAT=Ss) and responds to `status`/`goto`/
`snapshot` across many separate shell calls.

The `proc?.stderr` startup-error branch is removed since both platforms
now spawn with `stdio: 'ignore'`; both fall through to the on-disk
`browse-startup-error.log` written by `server.ts`'s start().catch.

* fix(design): bump image-gen timeout to 240s + pin gpt-image-2

The design binary calls /v1/responses (gpt-4o + image_generation tool,
quality:high, 1536x1024) but aborted the request after a hardcoded 120s.
That class of request consistently takes ~140-160s end-to-end, so every
generate/variants/evolve/iterate call aborted before the image returned.

In /design-shotgun this cascades: Step 3c launches N parallel agents,
each calling `$D generate`, each aborts at 120s and retries, all fail,
the comparison board never opens — the skill appears to hang indefinitely.

Reproduced the exact API call with a longer budget: HTTP 200, valid
image, 143.5s. A real /design-shotgun run after the patch generated 3
variants in parallel at 150.0s / 161.0s / 152.1s, all exit 0 — note the
161s case, which a naive 150s bump would still have failed.

- Bump AbortController timeout 120_000 -> 240_000 in generate.ts,
  variants.ts, evolve.ts, iterate.ts (both call sites)
- Pin the image_generation tool to model "gpt-image-2"

design/test/variants-retry-after.test.ts: 5 pass, 0 fail. The
feedback-roundtrip.test.ts failures are a pre-existing browse-module
breakage (session.clearLoadedHtml undefined), unrelated to this change.

* test: fill coverage gaps for PRs #1606, #1612, #1620

Three cherry-picked PRs in this wave landed without unit-test coverage for
the specific invariant they protect:

  #1606 (@andrey-esipov) — LC_ALL=C pin in _gstack_gbrain_validate_varname
    8 tests by sourcing bin/gstack-gbrain-lib.sh and calling the validator
    directly. Asserts uppercase/digit/underscore accepted, lowercase
    REJECTED (the macOS-locale regression case), mixed-case rejected,
    LC_ALL=C scoping is local (doesn't leak to caller).

  #1612 (@bharat2913) — setsid daemonize via Node child_process.spawn
    4 static-invariant tests on browse/src/cli.ts. The actual setsid
    syscall is hard to assert without a real spawn, so we pin the source
    shape: nodeSpawn imported from child_process; non-Windows branch uses

* test(learnings): align injection-prevention tests with PR #1619 tagged-line shape

PR #1619 (preserve current entries in cross-project search) refactored
gstack-learnings-search to tag rows inline (`current\t<json>` vs
`cross\t<json>`) instead of filtering inside the bun block via
process.env.GSTACK_SEARCH_SLUG. The bun block no longer reads SLUG or
CROSS env vars — it parses the per-line tag and sets a per-entry
_crossProject flag.

The pre-existing test/learnings-injection.test.ts still asserted on the
old SLUG + CROSS env var shape. Updates:

  - Remove the SLUG env var assertion (no longer set on bash command line)
  - Remove the bun-block CROSS env var assertion (block reads the tag now,
    not the env)
  - Add a new positive assertion that the bun block parses the tag
    (sourceTag | tabIndex | crossProject)
  - Keep the shell-interpolation safety assertion unchanged — that's
    independent of the SLUG refactor

The CROSS env var is still SET on the bash command line (it controls
whether the cross-project find runs at all), but the bun child no longer
reads it. The existing "env vars set on bash command line" test continues
to pin that.

* test(fixtures): regenerate ship-SKILL.md golden baselines

ship/SKILL.md consumes the Confidence Calibration resolver via the
preamble pipeline. This wave's #1539 pre-emit verification gate extends
the resolver text, which propagated to ship/SKILL.md via gen:skill-docs.
The golden fixtures in test/fixtures/golden/ matched the pre-#1539 shape
and failed the host-config regression check.

Refreshes claude-ship-SKILL.md, codex-ship-SKILL.md, and factory-ship-SKILL.md
to match the current generated output. Matches the Daegu wave's bisect
commit 23 ("test(fixtures): regenerate ship-SKILL.md golden baselines").

* test(gbrain-detect): include gbrain_pooler_mode in schema regression (PR #1591)

PR #1591 (PgBouncer transaction-mode detection, @mikeangstadt) added
gbrain_pooler_mode to the gstack-gbrain-detect JSON output but did not
update the schema regression check in
test/gstack-gbrain-detect-mcp-mode.test.ts. Adding the key in alphabetical
order matching the rest of the schema array. Downstream sync-gbrain ignores
unknown keys, so this is forward-compat.

Without this, the test fails with a diff:
  + "gbrain_pooler_mode"
because keys is the actual set returned and the expected array was
pre-#1591.

Bumps VERSION 1.42.2.0 → 1.43.0.0 (MINOR per scale-aware bump rules: new
env-var surface GSTACK_SYNC_*_TIMEOUT_MS + GSTACK_CHROMIUM_NO_SANDBOX,
behavior expansion in browse/src/browser-manager.ts headless launch,
three skill-template prompt changes affecting /retro, /review,

* v1.43.3.0 fix(browse): headed-mode idle timer + onDisconnect target wrong BrowserManager for embedders (#1645)

* fix(browse): route 4 lifecycle handlers through activeBrowserManager indirection

Module-level idleCheckTick, parent watchdog, SIGTERM handler, and
buildFetchHandler's onDisconnect wire all read the module-level
BrowserManager directly. For embedders (gbrowser) that pass their
own instance into buildFetchHandler, the module-level instance
never has launchHeaded() called on it — connectionMode stays
'launched' forever, headed-mode early-returns never fire, and
after 30 min of HTTP idle the server self-terminates out from
under the overlay.

Adds `let activeBrowserManager: BrowserManager` at module scope
(symmetric with the existing `let activeShutdown` pattern).
buildFetchHandler retargets it at cfg.browserManager and CHAINS
cfg.browserManager.onDisconnect to activeShutdown, preserving any
caller-installed handler instead of clobbering it.

Six edit sites in browse/src/server.ts:
- Edit 1 (~705): declare activeBrowserManager
- Edit 2 (~596): extract idleCheckTick + __testInternals__ export
- Edit 3 (~658): parent watchdog reads activeBrowserManager
- Edit 4 (~1387): retarget + chain cfgBrowserManager.onDisconnect
- Edit 5 (verify): line 714 default stays in place
- Edit 6 (~1212): SIGTERM handler reads activeBrowserManager

* test(browse): pin idle timer + onDisconnect dual-instance fix behaviorally

Adds 5 behavioral tests to browse/test/server-factory.test.ts under
a new 'idle timer + onDisconnect dual-instance fix' describe block:

- T1 (CRITICAL — REGRESSION): headed embedder does not auto-shutdown
  at idle. Pins the bug this PR fixes.
- T2 (paired defensive): headless still auto-shuts down at idle.
  Catches a future refactor that breaks the inverse case.
- T3 (chain semantics): buildFetchHandler chains
  cfgBrowserManager.onDisconnect, preserving any caller-set handler.
  Uses .rejects.toThrow for the async shutdown path.
- T4 (tunnelActive): tunnel-active blocks idle-shutdown even in
  headless mode.
- T5 (static guard): exactly 3 module-level lifecycle sites use
  activeBrowserManager.getConnectionMode() — idleCheckTick, parent
  watchdog, SIGTERM. Catches refactor-introduced regressions before
  CI.

Reuses existing makeMinimalConfig() + __resetRegistry() patterns
from the factory contract tests. New makeMockBrowserManager() helper.
beforeEach also resets module state via setTunnelActive,
setLastActivity, and resetShutdownState from __testInternals__.

Also deletes the old 'idle check skips in headed mode' string-grep
test from browse/test/sidebar-ux.test.ts at line 1596. That test
would have passed even with the dual-instance bug present
(grepped for "=== 'headed'" + 'return' in the same window).
Behavioral coverage moved to server-factory.test.ts.

Verified: 33/33 tests pass in browse/test/server-factory.test.ts.

* v1.44.0.0 feat: long-lived sidebar — keepalive, restart, re-attach, scrollback replay (#1678)

* fix(browse): identity-based terminal-agent kill replaces pkill regex

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

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

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

Test changes:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Changes:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Test (browse/test/sidepanel-reattach.test.ts):
  * 8 static-grep tripwires for the load-bearing properties: state
    constant, backoff schedule, /pty-session/reattach wiring, 410
    short-circuit (no retry past lease window), 401 sticky-abort,
    r…
