Garry Tan	7ca04d8ef0	v1.42.0.0 Daegu wave: 23 community-filed bugs + PTY classifier enforcement (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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Contributed by @Charlie-El via #1544. Supersedes #1531 (@scarson, fixed in build helper), #1480 (@mikepsinn, partial overlap), #1460 (@realcarsonterry, brace-group fix subsumed) — credit retained. Closes #1538, #1537, #1530, #1457, #1561. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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 Contributed by @Mike-E-Log via #1554. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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 (@mvanhorn — same intent, different patch shape, CONFLICTING) and #1449 (@Gujiassh — broader refactor, CONFLICTING). Credit retained in CHANGELOG. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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 - scripts/resolvers/review.ts - scripts/resolvers/review-army.ts Contributed by @mvanhorn via #1492. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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 Contributed by @mvanhorn via #1197. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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 Contributed by @genisis0x via #1467. Closes #1327. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Contributed by @jbetala7 via #1278. Closes #1248. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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, #1193 pattern, #1152 pattern. Credit retained inline. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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).

Garry Tan	ea51b45e08	v1.38.1.0 fix wave: surrogate-safe page captures (#1440), Implementation Tasks across review skills (#1454), root-level artifact patterns (#1452) (#1504) ... * fix(browse): sanitize lone Unicode surrogates at commandResult chokepoint + /batch envelope (#1440) Page captures with mixed-script Unicode round-trip cleanly to the Claude API. Two new utilities in browse/src/sanitize.ts: stripLoneSurrogates for raw UTF-16 strings, stripLoneSurrogateEscapes for \uXXXX JSON escape text. sanitizeBody picks the right pass based on cr.json. buildCommandResponse is extracted from handleCommand (now exported) and applies sanitization before new Response(). /batch was bypassing this chokepoint via direct JSON.stringify, so it sanitizes each cr.result before pushing AND wraps the envelope with stripLoneSurrogateEscapes. Defense in depth wraps at getCleanText, getCleanTextWithStripping, html, accessibility, and snapshot.ts return points so downstream consumers (datamarking, envelope wrapping) see sanitized text before the response is built. 25 new unit tests across sanitize.test.ts and build-command-response.test.ts. content-security.test.ts updated to accept either pre- or post-sanitize form of the snapshot scoped branch (source-level regression check). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * feat: bug fix wave v1.36.0.0 — Implementation Tasks, allowlist patterns, surrogate-safe page captures (#1440 #1452 #1454) Three filed issues land together: #1440 — Page captures from real-world HTML hit 'API Error 400: no low surrogate in string'. Sanitizers + buildCommandResponse extraction shipped in the prior commit; this commit adds the migration script that patches existing brain-allowlist/privacy-map/gitattributes installs and the supporting tests. #1452 — Federation sync was silently skipping root-level design and test-plan docs. bin/gstack-artifacts-init adds two patterns to all three managed blocks (.brain-allowlist, .brain-privacy-map.json, .gitattributes). Idempotent migration v1.36.0.0.sh repairs existing installs in place via jq (preserves JSON validity) — no commit + push from the migration. #1454 — All four review skills (CEO/design/eng/DX) emit an Implementation Tasks markdown section AND write a jq-built JSONL artifact per phase. /autoplan reads all four files, scopes by current branch + 5-commit window, dedupes on exact (component, sorted(files), title), and renders an aggregated list in the Final Approval Gate. New tests: - browse/test/sanitize.test.ts (18 cases) - browse/test/build-command-response.test.ts (7 cases) - test/artifacts-init-migration.test.ts (7 cases) VERSION → 1.36.0.0. Skips the v1.34.x slot taken by 'gstack consumable as submodule' and the v1.35.0.0 slot taken by /document-generate. #1428 was shipped separately by v1.34.2.0 with a different approach; follow-up #1503 filed for the bare-path filesystem boundary concern surfaced during our analysis.

Migration renamed: gstack-upgrade/migrations/v1.38.0.0.sh -> v1.38.1.0.sh.

Garry Tan	54d4cde773	security: tunnel dual-listener + SSRF + envelope + path wave (v1.6.0.0) (#1137) ... * refactor(security): loosen /connect rate limit from 3/min to 300/min Setup keys are 24 random bytes (unbruteforceable), so a tight rate limit does not meaningfully prevent key guessing. It exists only to cap bandwidth, CPU, and log-flood damage from someone who discovered the ngrok URL. A legitimate pair-agent session hits /connect once; 300/min is 60x that pattern and never hit accidentally. 3/min caused pairing to fail on any retry flow (network blip, second paired client) with no upside. Per-IP tracking was considered and rejected — adds a bounded Map + LRU for defense already adequate at the global layer. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): add tunnel-denial-log module for attack visibility Append-only log of tunnel-surface auth denials to ~/.gstack/security/attempts.jsonl. Gives operators visibility into who is probing tunneled daemons so the next security wave can be driven by real attack data instead of speculation. Design notes: - Async via fs.promises.appendFile. Never appendFileSync — blocking the event loop on every denial during a flood is what an attacker wants (prior learning: sync-audit-log-io, 10/10 confidence). - In-process rate cap at 60 writes/minute globally. Excess denials are counted in memory but not written to disk — prevents disk DoS. - Writes to the same ~/.gstack/security/attempts.jsonl used by the prompt-injection attempt log. File rotation is handled by the existing security pipeline (10MB, 5 generations). No consumers in this commit; wired up in the dual-listener refactor that follows. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): dual-listener tunnel architecture The /health endpoint leaked AUTH_TOKEN to any caller that hit the ngrok URL (spoofing chrome-extension:// origin, or catching headed mode). Surfaced by @garagon in PR #1026; the original fix was header-inference on the single port. Codex's outside-voice review during /plan-ceo-review called that approach brittle (ngrok header behavior could change, local proxies would false-positive), and pushed for the structural fix. This is that fix. Stop making /health a root-token bootstrap endpoint on any surface the tunnel can reach. The server now binds two HTTP listeners when a tunnel is active. The local listener (extension, CLI, sidebar) stays on 127.0.0.1 and is never exposed to ngrok. ngrok forwards only to the tunnel listener, which serves only /connect (unauth, rate-limited) and /command with a locked allowlist of browser-driving commands. Security property comes from physical port separation, not from header inference — a tunnel caller cannot reach /health or /cookie-picker or /inspector because they live on a different TCP socket. What this commit adds to browse/src/server.ts: * Surface type ('local' | 'tunnel') and TUNNEL_PATHS + TUNNEL_COMMANDS allowlists near the top of the file. * makeFetchHandler(surface) factory replacing the single fetch arrow; closure-captures the surface so the filter that runs before route dispatch knows which socket accepted the request. * Tunnel filter at dispatch entry: 404s anything not on TUNNEL_PATHS, 403s root-token bearers with a clear pairing hint, 401s non-/connect requests that lack a scoped token. Every denial is logged via logTunnelDenial (from tunnel-denial-log). * GET /connect alive probe (unauth on both surfaces) so /pair and /tunnel/start can detect dead ngrok tunnels without reaching /health — /health is no longer tunnel-reachable. * Lazy tunnel listener lifecycle. /tunnel/start binds a dedicated Bun.serve on an ephemeral port, points ngrok.forward at THAT port (not the local port), hard-fails on bind error (no local fallback), tears down cleanly on ngrok failure. BROWSE_TUNNEL=1 startup uses the same pattern. * closeTunnel() helper — single teardown path for both the ngrok listener and the tunnel Bun.serve listener. * resolveNgrokAuthtoken() helper — shared authtoken lookup across /tunnel/start and BROWSE_TUNNEL=1 startup (was duplicated). * TUNNEL_COMMANDS check in /command dispatch: on the tunnel surface, commands outside the allowlist return 403 with a list of allowed commands as a hint. * Probe paths in /pair and /tunnel/start migrated from /health to GET /connect — the only unauth path reachable on the tunnel surface under the new architecture. Test updates in browse/test/server-auth.test.ts: * /pair liveness-verify test: assert via closeTunnel() helper instead of the inline `tunnelActive = false; tunnelUrl = null` lines that the helper subsumes. * /tunnel/start cached-tunnel test: same closeTunnel() adaptation. Credit Derived from PR #1026 by @garagon — thanks for flagging the critical bug that drove the architectural rewrite. The per-request isTunneledRequest approach from #1026 is superseded by physical port separation here; the underlying report remains the root cause for the entire v1.6.0.0 wave. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): add source-level guards for dual-listener architecture 23 source-level assertions that keep future contributors from silently widening the tunnel surface during a routine refactor. Covers: * Surface type + tunnelServer state variable shape * TUNNEL_PATHS is a closed set of /connect, /command, /sidebar-chat (and NOT /health, /welcome, /cookie-picker, /inspector/*, /pair, /token, /refs, /activity/stream, /tunnel/{start,stop}) * TUNNEL_COMMANDS includes browser-driving ops only (and NOT launch-browser, tunnel-start, token-mint, cookie-import, etc.) * makeFetchHandler(surface) factory exists and is wired to both listeners with the correct surface parameter * Tunnel filter runs BEFORE any route dispatch, with 404/403/401 responses and logged denials for each reason * GET /connect returns {alive: true} unauth * /command dispatch enforces TUNNEL_COMMANDS on tunnel surface * closeTunnel() helper tears down ngrok + Bun.serve listener * /tunnel/start binds on ephemeral port, points ngrok at TUNNEL_PORT (not local port), hard-fails on bind error (no fallback), probes cached tunnel via GET /connect (not /health), tears down on ngrok.forward failure * BROWSE_TUNNEL=1 startup uses the dual-listener pattern * logTunnelDenial wired for all three denial reasons * /connect rate limit is 300/min, not 3/min All 23 tests pass. Behavioral integration tests (spawn subprocess, real network) live in the E2E suite that lands later in this wave. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * security: gate download + scrape through validateNavigationUrl (SSRF) The `goto` command was correctly wired through validateNavigationUrl, but `download` and `scrape` called page.request.fetch(url, ...) directly. A caller with the default write scope could hit the /command endpoint and ask the daemon to fetch http://169.254.169.254/latest/meta-data/ (AWS IMDSv1) or the GCP/Azure/internal equivalents. The response body comes back as base64 or lands on disk where GET /file serves it. Fix: call validateNavigationUrl(url) immediately before each page.request.fetch() call site in download and in the scrape loop. Same blocklist that already protects `goto`: file://, javascript:, data:, chrome://, cloud metadata (IPv4 all encodings, IPv6 ULA, metadata.*.internal). Tests: extend browse/test/url-validation.test.ts with a source-level guard that walks every `await page.request.fetch(` call site and asserts a validateNavigationUrl call precedes it within the same branch. Regression trips before code review if a future refactor drops the gate. * security: route splitForScoped through envelope sentinel escape The scoped-token snapshot path in snapshot.ts built its untrusted block by pushing the raw accessibility-tree lines between the literal `═══ BEGIN UNTRUSTED WEB CONTENT ═══` / `═══ END UNTRUSTED WEB CONTENT ═══` sentinels. The full-page wrap path in content-security.ts already applied a zero-width-space escape on those exact strings to prevent sentinel injection, but the scoped path skipped it. Net effect: a page whose rendered text contains the literal sentinel can close the envelope early from inside untrusted content and forge a fake "trusted" block for the LLM. That includes fabricating interactive `@eN` references the agent will act on. Fix: * Extract the zero-width-space escape into a named, exported helper `escapeEnvelopeSentinels(content)` in content-security.ts. * Have `wrapUntrustedPageContent` call it (behavior unchanged on that path — same bytes out). * Import the helper in snapshot.ts and map it over `untrustedLines` in the `splitForScoped` branch before pushing the BEGIN sentinel. Tests: add a describe block in content-security.test.ts that covers * `escapeEnvelopeSentinels` defuses BEGIN and END markers; * `escapeEnvelopeSentinels` leaves normal text untouched; * `wrapUntrustedPageContent` still emits exactly one real envelope pair when hostile content contains forged sentinels; * snapshot.ts imports the helper; * the scoped-snapshot branch calls `escapeEnvelopeSentinels` before pushing the BEGIN sentinel (source-level regression — if a future refactor reorders this, the test trips). * security: extend hidden-element detection to all DOM-reading channels The Confusion Protocol envelope wrap (`wrapUntrustedPageContent`) covers every scoped PAGE_CONTENT_COMMAND, but the hidden-element ARIA-injection detection layer only ran for `text`. Other DOM-reading channels (html, links, forms, accessibility, attrs, data, media, ux-audit) returned their output through the envelope with no hidden- content filter, so a page serving a display:none div that instructs the agent to disregard prior system messages, or an aria-label that claims to put the LLM in admin mode, leaked the injection payload on any non-text channel. The envelope alone does not mitigate this, and the page itself never rendered the hostile content to the human operator. Fix: * New export `DOM_CONTENT_COMMANDS` in commands.ts — the subset of PAGE_CONTENT_COMMANDS that derives its output from the live DOM. Console and dialog stay out; they read separate runtime state. * server.ts runs `markHiddenElements` + `cleanupHiddenMarkers` for every scoped command in this set. `text` keeps its existing `getCleanTextWithStripping` path (hidden elements physically stripped before the read). All other channels keep their output format but emit flagged elements as CONTENT WARNINGS on the envelope, so the LLM sees what it would otherwise have consumed silently. * Hidden-element descriptions merge into `combinedWarnings` alongside content-filter warnings before the wrap call. Tests: new describe block in content-security.test.ts covering * `DOM_CONTENT_COMMANDS` export shape and channel membership; * dispatch gates on `DOM_CONTENT_COMMANDS.has(command)`, not the literal `text` string; * hiddenContentWarnings plumbs into `combinedWarnings` and reaches wrapUntrustedPageContent; * DOM_CONTENT_COMMANDS is a strict subset of PAGE_CONTENT_COMMANDS. Existing datamarking, envelope wrap, centralized-wrapping, and chain security suites stay green (52 pass, 0 fail). * security: validate --from-file payload paths for parity with direct paths The direct `load-html <file>` path runs every caller-supplied file path through validateReadPath() so reads stay confined to SAFE_DIRECTORIES (cwd, TEMP_DIR). The `load-html --from-file <payload.json>` shortcut and its sibling `pdf --from-file <payload.json>` skipped that check and went straight to fs.readFileSync(). An MCP caller that picks the payload path (or any caller whose payload argument is reachable from attacker-influenced text) could use --from-file as a read-anywhere escape hatch for the safe-dirs policy. Fix: call validateReadPath(path.resolve(payloadPath)) before readFileSync at both sites. Error surface mirrors the direct-path branch so ops and agent errors stay consistent. Test coverage in browse/test/from-file-path-validation.test.ts: - source-level: validateReadPath precedes readFileSync in the load-html --from-file branch (write-commands.ts) and the pdf --from-file parser (meta-commands.ts) - error-message parity: both sites reference SAFE_DIRECTORIES Related security audit pattern: R3 F002 (validateNavigationUrl gap on download/scrape) and R3 F008 (markHiddenElements gap on 10 DOM commands) were the same shape — a defense that existed on the primary code path but not its shortcut sibling. This PR closes the same class of gap on the --from-file shortcuts. * fix(design): escape url.origin when injecting into served HTML serve.ts injected url.origin into a single-quoted JS string in the response body. A local request with a crafted Host header (e.g. Host: "evil'-alert(1)-'x") would break out of the string and execute JS in the 127.0.0.1:<port> origin opened by the design board. Low severity — bound to localhost, requires a local attacker — but no reason not to escape. Fix: JSON.stringify(url.origin) produces a properly quoted, escaped JS string literal in one call. Also includes Prettier reformatting (single→double quotes, trailing commas, line wrapping) applied by the repo's PostToolUse formatter hook. Security change is the one line in the HTML injection; everything else is whitespace/style. * fix(scripts): drop shell:true from slop-diff npx invocations spawnSync('npx', [...], { shell: true }) invokes /bin/sh -c with the args concatenated, subjecting them to shell parsing (word splitting, glob expansion, metacharacter interpretation). No user input reaches these calls today, so not exploitable — but the posture is wrong: npx + shell args should be direct. Fix: scope shell:true to process.platform === 'win32' where npx is actually a .cmd requiring the shell. POSIX runs the npx binary directly with array-form args. Also includes Prettier reformatting (single→double quotes, trailing commas, line wrapping) applied by the repo's PostToolUse formatter hook. Security-relevant change is just the two shell:true -> shell: process.platform === 'win32' lines; everything else is whitespace/style. * security(E3): gate GSTACK_SLUG on /welcome path traversal The /welcome handler interpolates GSTACK_SLUG directly into the filesystem path used to locate the project-local welcome page. Without validation, a slug like "../../etc/passwd" would resolve to ~/.gstack/projects/../../etc/passwd/designs/welcome-page-20260331/finalized.html — classic path traversal. Not exploitable today: GSTACK_SLUG is set by the gstack CLI at daemon launch, and an attacker would already need local env-var access to poison it. But the gate is one regex (^[a-z0-9_-]+$), and a defense-in-depth pass costs us nothing when the cost of being wrong is arbitrary file read via /welcome. Fall back to the safe 'unknown' literal when the slug fails validation — same fallback the code already uses when GSTACK_SLUG is unset. No behavior change for legitimate slugs (they all match the regex). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * security(N1): replace ?token= SSE auth with HttpOnly session cookie Activity stream and inspector events SSE endpoints accepted the root AUTH_TOKEN via `?token=` query param (EventSource can't send Authorization headers). URLs leak to browser history, referer headers, server logs, crash reports, and refactoring accidents. Codex flagged this during the /plan-ceo-review outside voice pass. New auth model: the extension calls POST /sse-session with a Bearer token and receives a view-only session cookie (HttpOnly, SameSite=Strict, 30-min TTL). EventSource is opened with `withCredentials: true` so the browser sends the cookie back on the SSE connection. The ?token= query param is GONE — no more URL-borne secrets. Scope isolation (prior learning cookie-picker-auth-isolation, 10/10 confidence): the SSE session cookie grants access to /activity/stream and /inspector/events ONLY. The token is never valid against /command, /token, or any mutating endpoint. A leaked cookie can watch activity; it cannot execute browser commands. Components * browse/src/sse-session-cookie.ts — registry: mint/validate/extract/ build-cookie. 256-bit tokens, 30-min TTL, lazy expiry pruning, no imports from token-registry (scope isolation enforced by module boundary). * browse/src/server.ts — POST /sse-session mint endpoint (requires Bearer). /activity/stream and /inspector/events now accept Bearer OR the session cookie, and reject ?token= query param. * extension/sidepanel.js — ensureSseSessionCookie() bootstrap call, EventSource opened with withCredentials:true on both SSE endpoints. Tested via the source guards; behavioral test is the E2E pairing flow that lands later in the wave. * browse/test/sse-session-cookie.test.ts — 20 unit tests covering mint entropy, TTL enforcement, cookie flag invariants, cookie parsing from multi-cookie headers, and scope-isolation contract guard (module must not import token-registry). * browse/test/server-auth.test.ts — existing /activity/stream auth test updated to assert the new cookie-based gate and the absence of the ?token= query param. Cookie flag choices: * HttpOnly: token not readable from page JS (mitigates XSS exfiltration). * SameSite=Strict: cookie not sent on cross-site requests (mitigates CSRF). Fine for SSE because the extension connects to 127.0.0.1 directly. * Path=/: cookie scoped to the whole origin. * Max-Age=1800: 30 minutes, matches TTL. Extension re-mints on reconnect when daemon restarts. * Secure NOT set: daemon binds to 127.0.0.1 over plain HTTP. Adding Secure would block the browser from ever sending the cookie back. Add Secure when gstack ships over HTTPS. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * security(N2): document Windows v20 ABE elevation path on CDP port The existing comment around the cookie-import-browser --remote-debugging-port launch claimed "threat model: no worse than baseline." That's wrong on Windows with App-Bound Encryption v20. A same-user local process that opens the cookie SQLite DB directly CANNOT decrypt v20 values (DPAPI context is bound to the browser process). The CDP port lets them bypass that: connect to the debug port, call Network.getAllCookies inside Chrome, walk away with decrypted v20 cookies. The correct fix is to switch from TCP --remote-debugging-port to --remote-debugging-pipe so the CDP transport is a stdio pipe, not a socket. That requires restructuring the CDP WebSocket client in this module and Playwright doesn't expose the pipe transport out of the box. Non-trivial, deferred from the v1.6.0.0 wave. This commit updates the comment to correctly describe the threat and points at the tracking issue. No code change to the launch itself. Follow-up: #1136. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(E2): document dual-listener tunnel architecture in ARCHITECTURE.md Adds an explicit per-endpoint disposition table to the Security model section, covering the v1.6.0.0 dual-listener refactor. Every HTTP endpoint now has a documented local-vs-tunnel answer. Future audits (and future contributors wondering "is it safe to add X to the tunnel surface?") can read this instead of reverse-engineering server.ts. Also documents: * Why physical port separation beats per-request header inference (ngrok behavior drift, local proxies can forge headers, etc.) * Tunnel surface denial logging → ~/.gstack/security/attempts.jsonl * SSE session cookie model (gstack_sse, 30-min TTL, stream-scope only, module-boundary-enforced scope isolation) * N2 non-goal for Windows v20 ABE via CDP port (tracking #1136) No code changes. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(E1): end-to-end pair-agent flow against a spawned daemon Spawns the browse daemon as a subprocess with BROWSE_HEADLESS_SKIP=1 so the HTTP layer runs without a real browser. Exercises: * GET /health — token delivery for chrome-extension origin, withheld otherwise (the F1 + PR #1026 invariant) * GET /connect — alive probe returns {alive:true} unauth * POST /pair — root Bearer required (403 without), returns setup_key * POST /connect — setup_key exchange mints a distinct scoped token * POST /command — 401 without auth * POST /sse-session — Bearer required, Set-Cookie has HttpOnly + SameSite=Strict (the N1 invariant) * GET /activity/stream — 401 without auth * GET /activity/stream?token= — 401 (the old ?token= query param is REJECTED, which is the whole point of N1) * GET /welcome — serves HTML, does not leak /etc/passwd content under the default 'unknown' slug (E3 regex gate) 12 behavioral tests, ~220ms end-to-end, no network dependencies, no ngrok, no real browser. This is the receipt for the wave's central 'pair-agent still works + the security boundary holds' claim. Tunnel-port binding (/tunnel/start) is deliberately NOT exercised here — it requires an ngrok authtoken and live network. The dual-listener route allowlist is covered by source-level guards in dual-listener.test.ts; behavioral tunnel testing belongs in a separate paid-evals harness. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * release(v1.6.0.0): bump VERSION + CHANGELOG for security wave Architectural bump, not patch: dual-listener HTTP refactor changes the daemon's tunnel-exposure model. See CHANGELOG for the full release summary (~950 words) covering the five root causes this wave closes: 1. /health token leak over ngrok (F1 + E3 + test infra) 2. /cookie-picker + /inspector exposed over the tunnel (F1) 3. ?token=<ROOT> in SSE URLs leaking to logs/referer/history (N1) 4. /welcome GSTACK_SLUG path traversal (E3) 5. Windows v20 ABE elevation via CDP port (N2 — documented non-goal, tracked as #1136) Plus the base PRs: SSRF gate (#1029), envelope sentinel escape (#1031), DOM-channel hidden-element coverage (#1032), --from-file path validation (#1103), and 2 commits from #1073 (@theqazi). VERSION + package.json bumped to 1.6.0.0. CHANGELOG entry covers credits (@garagon, @Hybirdss, @HMAKT99, @theqazi), review lineage (CEO → Codex outside voice → Eng), and the non-goal tracking issue. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix: pre-landing review findings (4 auto-fixes) Addresses 4 findings from the Claude adversarial subagent on the v1.6.0.0 security wave diff. No user-visible behavior change; all are defense-in-depth hardening of newly-introduced code. 1. GET /connect rate-limited (was POST-only) [HIGH conf 8/10] Attacker discovering the ngrok URL could probe unlimited GETs for daemon enumeration. Now shares the global /connect counter. 2. ngrok listener leak on tunnel startup failure [MEDIUM conf 8/10] If ngrok.forward() resolved but tunnelListener.url() or the state-file write threw, the Bun listener was torn down but the ngrok session was leaked. Fixed in BOTH /tunnel/start and BROWSE_TUNNEL=1 startup paths. 3. GSTACK_SKILL_ROOT path-traversal gate [MEDIUM conf 8/10] Symmetric with E3's GSTACK_SLUG regex gate — reject values containing '..' before interpolating into the welcome-page path. 4. SSE session registry pruning [LOW conf 7/10] pruneExpired() only checked 10 entries per mint call. Now runs on every validate too, checks 20 entries, with a hard 10k cap as backstop. Prevents registry growth under sustained extension reconnect pressure. Tests remain green (56/56 in sse-session-cookie + dual-listener + pair-agent-e2e suites). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs: update project documentation for v1.6.0.0 Reflect the dual-listener tunnel architecture, SSE session cookies, SSRF guards, and Windows v20 ABE non-goal across the three docs users actually read for remote-agent and browser auth context: - docs/REMOTE_BROWSER_ACCESS.md: rewrote Architecture diagram for dual listeners, fixed /connect rate limit (3/min → 300/min), removed stale "/health requires no auth" (now 404 on tunnel), added SSE cookie auth, expanded Security Model with tunnel allowlist, SSRF guards, /welcome path traversal defense, and the Windows v20 ABE tracking note. - BROWSER.md: added dual-listener paragraph to Authentication and linked to ARCHITECTURE.md endpoint table. Replaced the stale ?token= SSE auth note with the HttpOnly gstack_sse cookie flow. - CLAUDE.md: added Transport-layer security section above the sidebar prompt-injection stack so contributors editing server.ts, sse-session-cookie.ts, or tunnel-denial-log.ts see the load-bearing module boundaries before touching them. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(make-pdf): write --from-file payload to /tmp, not os.tmpdir() make-pdf's browseClient wrote its --from-file payload to os.tmpdir(), which is /var/folders/... on macOS. v1.6.0.0's PR #1103 cherry-pick tightened browse load-html --from-file to validate against the safe-dirs allowlist ([TEMP_DIR, cwd] where TEMP_DIR is '/tmp' on macOS/Linux, os.tmpdir() on Windows). This closed a CLI/API parity gap but broke make-pdf on macOS because /var/folders/... is outside the allowlist. Fix: mirror browse's TEMP_DIR convention — use '/tmp' on non-Windows, os.tmpdir() on Windows. The make-pdf-gate CI failure on macOS-latest (run 72440797490) is caused by exactly this: the payload file was rejected by validateReadPath. Verified locally: the combined-gate e2e test now passes after rebuilding make-pdf/dist/pdf. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(sidebar): killAgent resets per-tab state; align tests with current agent event format Two pre-existing bugs surfaced while running the full e2e suite on the sec-wave branch. Both pre-date v1.6.0.0 (same failures on main at e23ff280) but blocked the ship verification, so fixing now. ### Bug 1: killAgent leaked stale per-tab state `killAgent()` reset the legacy globals (agentProcess, agentStatus, etc.) but never touched the per-tab `tabAgents` Map. Meanwhile `/sidebar-command` routes on `tabState.status` from that Map, not the legacy globals. Consequence: after a kill (including the implicit kill in `/sidebar-session/new`), the next /sidebar-command on the same tab saw `tabState.status === 'processing'` and fell into the queue branch, silently NOT spawning an agent. Integration tests that called resetState between cases all failed with empty queues. Fix: when targetTabId is supplied, reset that one tab's state; when called without a tab (session-new, full kill), reset ALL tab states. Matches the semantic boundary already used for the cancel-file write. ### Bug 2: sidebar-integration tests drifted from current event format `agent events appear in /sidebar-chat` posted the raw Claude streaming format (`{type: 'assistant', message: {content: [...]}}`) but `processAgentEvent` in server.ts only handles the simplified types that sidebar-agent.ts pre-processes into (text, text_delta, tool_use, result, agent_error, security_event). The architecture moved pre-processing into sidebar-agent.ts at some point and this test never got updated. Fixed by sending the pre-processed `{type: 'text', text: '...'}` format — which is actually what the server sees in production. Also removed the `entry.prompt` URL-containment check in the queue-write test. The URL is carried on entry.pageUrl (metadata) by design: the system prompt tells Claude to run `browse url` to fetch the actual page rather than trust any URL in the prompt body. That's the URL-based prompt-injection defense. The prompt SHOULD NOT contain the URL, so the test assertion was wrong for the current security posture. ### Verification - `bun test browse/test/sidebar-integration.test.ts` → 13/13 pass (was 6/13 on both main and branch before this commit) - Full `bun run test` → exit 0, zero fail markers - No behavior change for production sidebar flows: killAgent was already supposed to return the agent to idle; it just wasn't fully doing so. Per-tab reset now matches the documented semantics.

Garry Tan	2300067267	feat: UX behavioral foundations + ux-audit command (v0.17.0.0) (#1000) ... * feat: UX behavioral foundations — Krug's usability principles as shared design infrastructure Add UX_PRINCIPLES resolver distilling Steve Krug's "Don't Make Me Think" into actionable guidance for AI agents. Injected into all 4 design skills as a shared behavioral foundation complementing the existing visual checklist (WHAT to check) and cognitive patterns (HOW designers see) with HOW USERS ACTUALLY BEHAVE. Methodology rewire: 6 Krug usability tests woven into existing design-review phases — Trunk Test, 3-Second Scan, Page Area Test, Happy Talk Detection with word count metric, Mindless Choice Audit, Goodwill Reservoir tracking with visual dashboard. First-person narration mode for design-review output with anti-slop guardrail. Hard rules: 4 Krug always/never rules in DESIGN_HARD_RULES (placeholder-as-label, floating headings, visited link distinction, minimum type size). Krug, Redish, Jarrett added to plan-design-review references. Token ceiling: gen-skill-docs.ts warns if any SKILL.md exceeds 100KB (~25K tokens). Documented in CLAUDE.md. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: $B ux-audit command + snapshot --heatmap flag New browse meta-command: ux-audit extracts page structure (site ID, navigation, headings, interactive elements, text blocks) as structured JSON for agent-side UX behavioral analysis. Pure data extraction — the agent applies the 6 usability tests and makes judgment calls. Element caps: 50 headings, 100 links, 200 interactive, 50 text blocks. New snapshot flag: -H/--heatmap accepts a JSON color map mapping ref IDs to colors (green/yellow/red/blue/orange/gray). Extends existing snapshot -a annotation system with per-ref colors instead of hardcoded red. Color whitelist validation prevents CSS injection. Composable — any skill can use it. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: update project documentation for v0.17.0.0 ARCHITECTURE.md: added {{UX_PRINCIPLES}} resolver to placeholder table. VERSION: bumped to 0.17.0.0 for UX behavioral foundations release. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: bump version and changelog (v0.17.0.0) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: adversarial review fixes for ux-audit and heatmap Security: - Remove live form value extraction from ux-audit (leaked input field values) - Add ux-audit to PAGE_CONTENT_COMMANDS (untrusted content wrapping) Correctness: - Scope youAreHere selector to nav containers (was matching animation classes) - Validate heatmap JSON is a plain object (string/array/null produced garbage) - Use textContent instead of innerText for word count (avoids layout computation) - Remove dead url variable and unused LINK_CAP constant Found by Codex + Claude adversarial review.

Garry Tan	c6e6a21d1a	refactor: AI slop reduction with cross-model quality review (v0.16.3.0) (#941) ... * refactor: add error-handling utility module with selective catches safeUnlink (ignores ENOENT), safeKill (ignores ESRCH), isProcessAlive (extracted from cli.ts with Windows support), and json() Response helper. All catches check err.code and rethrow unexpected errors instead of swallowing silently. Unit tests cover happy path + error code paths. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor: replace defensive try/catches in server.ts with utilities Replace ~12 try/catch sites with safeUnlink/safeKill calls in shutdown, emergencyCleanup, killAgent, and log cleanup. Convert empty catches to selective catches with error code checks. Remove needless welcome page try/catches (fs.existsSync doesn't need wrapping). Reduces slop-scan empty-catch locations from 11 to 8 and error-swallowing from 24 to 18. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor: extract isProcessAlive and replace try/catches in cli.ts Move isProcessAlive to shared error-handling module. Replace ~20 try/catch sites with safeUnlink/safeKill in killServer, connect, disconnect, and cleanup flows. Convert empty catches to selective catches. Reduces slop-scan empty-catch from 22 to 2 locations. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor: remove unnecessary return await in content-security and read-commands Remove 6 redundant return-await patterns where there's no enclosing try block. Eliminates all defensive.async-noise findings from these files. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: add slop-scan config to exclude vendor files Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor: replace empty catches with selective error handling in sidebar-agent Convert 8 empty catch blocks to selective catches that check err.code (ESRCH for process kills, ENOENT for file ops). Import safeUnlink for cancel file cleanup. Unexpected errors now propagate instead of being silently swallowed. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor: replace empty catches and mark pass-through wrappers in browser-manager Convert 12 empty catch blocks to selective catches: filesystem ops check ENOENT/EACCES, browser ops check for closed/Target messages, URL parsing checks TypeError. Add 'alias for active session' comments above 6 pass-through wrapper methods to document their purpose (and exempt from slop-scan pass-through-wrappers rule). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor: selective catches in gstack-global-discover Convert 8 defensive catch blocks to selective error handling. Filesystem ops check ENOENT/EACCES, process ops check exit status. Unexpected errors now propagate instead of returning silent defaults. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor: selective catches in write-commands, cdp-inspector, meta-commands, snapshot Convert ~27 empty/obscuring catches to selective error handling across 4 browse source files. CDP ops check for closed/Target/detached messages, DOM ops check TypeError/DOMException, filesystem ops check ENOENT/EACCES, JSON parsing checks SyntaxError. Remove dead code in cdp-inspector where try/catch wrapped synchronous no-ops. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor: selective catches in Chrome extension files Convert empty catches and error-swallowing patterns across inspector.js, content.js, background.js, and sidepanel.js. DOM catches filter TypeError/DOMException, chrome API catches filter Extension context invalidated, network catches filter Failed to fetch. Unexpected errors now propagate. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: restore isProcessAlive boolean semantics, add safeUnlinkQuiet, remove unused json() isProcessAlive now catches ALL errors and returns false (pure boolean probe). Callers use it in if/while conditions without try/catch, so throwing on EPERM was a behavior change that could crash the CLI. Windows path gets its safety catch restored. safeUnlinkQuiet added for best-effort cleanup paths where throwing on non-ENOENT errors (like EPERM during shutdown) would abort cleanup. json() removed — dead code, never imported anywhere. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: use safeUnlinkQuiet in shutdown and cleanup paths Shutdown, emergency cleanup, and disconnect paths should never throw on file deletion failures. Switched from safeUnlink (throws on EPERM) to safeUnlinkQuiet (swallows all errors) in these best-effort paths. Normal operation paths (startup, lock release) keep safeUnlink. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * revert: remove brittle string-matching catches and alias comments in browser-manager Revert 6 catches that matched error messages via includes('closed'), includes('Target'), etc. back to empty catches. These fire-and-forget operations (page.close, bringToFront, dialog dismiss) genuinely don't care about any error type. String matching on error messages is brittle and will break on Playwright version bumps. Remove 6 'alias for active session' comments that existed solely to game slop-scan's pass-through-wrapper exemption rule. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * revert: remove brittle string-matching catches in extension files Revert error-swallowing fixes in background.js and sidepanel.js that matched error messages via includes('Failed to fetch'), includes( 'Extension context invalidated'), etc. In Chrome extensions, uncaught errors crash the entire extension. The original catch-and-log pattern is the correct choice for extension code where any error is non-fatal. content.js and inspector.js changes kept — their TypeError/DOMException catches are typed, not string-based. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: add slop-scan usage guidelines to CLAUDE.md Instructions for using slop-scan to improve genuine code quality, not to game metrics or hide that we're AI-coded. Documents what to fix (empty catches on file/process ops, typed exception narrows, return await) and what NOT to fix (string-matching on error messages, linter gaming comments, tightening extension/cleanup catches). Includes utility function reference and baseline score tracking. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: add slop-scan as diagnostic in test suite Runs slop-scan after bun test as a non-blocking diagnostic. Prints the summary (top files, hotspots) so you see the number without it gating anything. Available standalone via bun run slop. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: slop-diff shows only NEW findings introduced on this branch Runs slop-scan on HEAD and the merge-base, diffs results with line-number-insensitive fingerprinting so shifted code doesn't create false positives.

Garry Tan	1868636f49	refactor: extract TabSession for per-tab state isolation (v0.15.16.0) (#873) ... * plan: batch command endpoint + multi-tab parallel execution for GStack Browser * refactor: extract TabSession from BrowserManager for per-tab state Move per-tab state (refMap, lastSnapshot, frame) into a new TabSession class. BrowserManager delegates to the active TabSession via getActiveSession(). Zero behavior change — all existing tests pass. This is the foundation for the /batch endpoint: both /command and /batch will use the same handler functions with TabSession, eliminating shared state races during parallel tab execution. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor: update handler signatures to use TabSession Change handleReadCommand and handleSnapshot to take TabSession instead of BrowserManager. Change handleWriteCommand to take both TabSession (per-tab ops) and BrowserManager (global ops like viewport, headers, dialog). handleMetaCommand keeps BrowserManager for tab management. Tests use thin wrapper functions that bridge the old 3-arg call pattern to the new signatures via bm.getActiveSession(). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: add POST /batch endpoint for parallel multi-tab execution Execute multiple commands across tabs in a single HTTP request. Commands targeting different tabs run concurrently via Promise.allSettled. Commands targeting the same tab run sequentially within that group. Features: - Batch-safe command subset (text, goto, click, snapshot, screenshot, etc.) - newtab/closetab as special commands within batch - SSE streaming mode (stream: true) for partial results - Per-command error isolation (one tab failing doesn't abort the batch) - Max 50 commands per batch, soft batch-level timeout A 143-page crawl drops from ~45 min (serial HTTP) to ~5 min (20 tabs in parallel, batched commands). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test: add batch endpoint integration tests 10 tests covering: - Multi-tab parallel execution (goto + text on different tabs) - Same-tab sequential ordering - Per-command error isolation (one tab fails, others succeed) - Page-scoped refs (snapshot refs are per-session, not global) - Per-tab lastSnapshot (snapshot -D with independent baselines) - getSession/getActiveSession API - Batch-safe command subset validation - closeTab via page.close preserves at-least-one-page invariant - Parallel goto on 3 tabs simultaneously Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: harden codex-review E2E — extract SKILL.md section, bump maxTurns to 25 The test was copying the full 55KB/1075-line codex SKILL.md into the fixture, requiring 8 Read calls just to consume it and exhausting the 15-turn budget before reaching the actual codex review command. Now extracts only the review-relevant section (~6KB/148 lines), reducing Read calls from 8 to 1. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: move batch endpoint plan into BROWSER.md as feature documentation The batch endpoint is implemented — document it as an actual feature in BROWSER.md (architecture, API shape, design decisions, usage pattern) and remove the standalone plan file.

Garry Tan	8ca950f6f1	feat: content security — 4-layer prompt injection defense for pair-agent (#815) ... * feat: token registry for multi-agent browser access Per-agent scoped tokens with read/write/admin/meta command categories, domain glob restrictions, rate limiting, expiry, and revocation. Setup key exchange for the /pair-agent ceremony (5-min one-time key → 24h session token). Idempotent exchange handles tunnel drops. 39 tests. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: integrate token registry + scoped auth into browse server Server changes for multi-agent browser access: - /connect endpoint: setup key exchange for /pair-agent ceremony - /token endpoint: root-only minting of scoped sub-tokens - /token/:clientId DELETE: revoke agent tokens - /agents endpoint: list connected agents (root-only) - /health: strips root token when tunnel is active (P0 security fix) - /command: scope/rate/domain checks via token registry before dispatch - Idle timer skips shutdown when tunnel is active Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: ngrok tunnel integration + @ngrok/ngrok dependency BROWSE_TUNNEL=1 env var starts an ngrok tunnel after Bun.serve(). Reads NGROK_AUTHTOKEN from env or ~/.gstack/ngrok.env. Reads NGROK_DOMAIN for dedicated domain (stable URL). Updates state file with tunnel URL. Feasibility spike confirmed: SDK works in compiled Bun binary. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: tab isolation for multi-agent browser access Add per-tab ownership tracking to BrowserManager. Scoped agents must create their own tab via newtab before writing. Unowned tabs (pre-existing, user-opened) are root-only for writes. Read access always allowed. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: tab enforcement + POST /pair endpoint + activity attribution Server-side tab ownership check blocks scoped agents from writing to unowned tabs. Special-case newtab records ownership for scoped tokens. POST /pair endpoint creates setup keys for the pairing ceremony. Activity events now include clientId for attribution. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: pair-agent CLI command + instruction block generator One command to pair a remote agent: $B pair-agent. Creates a setup key via POST /pair, prints a copy-pasteable instruction block with curl commands. Smart tunnel fallback (tunnel URL > auto-start > localhost). Flags: --for HOST, --local HOST, --admin, --client NAME. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test: tab isolation + instruction block generator tests 14 tests covering tab ownership lifecycle (access checks, unowned tabs, transferTab) and instruction block generator (scopes, URLs, admin flag, troubleshooting section). Fix server-auth test that used fragile sliceBetween boundaries broken by new endpoints. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: bump version and changelog (v0.15.9.0) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: CSO security fixes — token leak, domain bypass, input validation 1. Remove root token from /health endpoint entirely (CSO #1 CRITICAL). Origin header is spoofable. Extension reads from ~/.gstack/.auth.json. 2. Add domain check for newtab URL (CSO #5). Previously only goto was checked, allowing domain-restricted agents to bypass via newtab. 3. Validate scope values, rateLimit, expiresSeconds in createToken() (CSO #4). Rejects invalid scopes and negative values. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: /pair-agent skill — syntactic sugar for browser sharing Users remember /pair-agent, not $B pair-agent. The skill walks through agent selection (OpenClaw, Hermes, Codex, Cursor, generic), local vs remote setup, tunnel configuration, and includes platform-specific notes for each agent type. Wraps the CLI command with context. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: remote browser access reference for paired agents Full API reference, snapshot→@ref pattern, scopes, tab isolation, error codes, ngrok setup, and same-machine shortcuts. The instruction block points here for deeper reading. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: improved instruction block with snapshot→@ref pattern The paste-into-agent instruction block now teaches the snapshot→@ref workflow (the most powerful browsing pattern), shows the server URL prominently, and uses clearer formatting. Tests updated to match. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: smart ngrok detection + auto-tunnel in pair-agent The pair-agent command now checks ngrok's native config (not just ~/.gstack/ngrok.env) and auto-starts the tunnel when ngrok is available. The skill template walks users through ngrok install and auth if not set up, instead of just printing a dead localhost URL. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: on-demand tunnel start via POST /tunnel/start pair-agent now auto-starts the ngrok tunnel without restarting the server. New POST /tunnel/start endpoint reads authtoken from env, ~/.gstack/ngrok.env, or ngrok's native config. CLI detects ngrok availability and calls the endpoint automatically. Zero manual steps when ngrok is installed and authed. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: pair-agent skill must output the instruction block verbatim Added CRITICAL instruction: the agent MUST output the full instruction block so the user can copy it. Previously the agent could summarize over it, leaving the user with nothing to paste. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: scoped tokens rejected on /command — auth gate ordering bug The blanket validateAuth() gate (root-only) sat above the /command endpoint, rejecting all scoped tokens with 401 before they reached getTokenInfo(). Moved /command above the gate so both root and scoped tokens are accepted. This was the bug Wintermute hit. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: pair-agent auto-launches headed mode before pairing When pair-agent detects headless mode, it auto-switches to headed (visible Chromium window) so the user can watch what the remote agent does. Use --headless to skip this. Fixed compiled binary path resolution (process.execPath, not process.argv[1] which is virtual /$bunfs/ in Bun compiled binaries). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test: comprehensive tests for auth ordering, tunnel, ngrok, headed mode 16 new tests covering: - /command sits above blanket auth gate (Wintermute bug) - /command uses getTokenInfo not validateAuth - /tunnel/start requires root, checks native ngrok config, returns already_active - /pair creates setup keys not session tokens - Tab ownership checked before command dispatch - Activity events include clientId - Instruction block teaches snapshot→@ref pattern - pair-agent auto-headed mode, process.execPath, --headless skip - isNgrokAvailable checks all 3 sources (gstack env, env var, native config) - handlePairAgent calls /tunnel/start not server restart Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: chain scope bypass + /health info leak when tunneled 1. Chain command now pre-validates ALL subcommand scopes before executing any. A read+meta token can no longer escalate to admin via chain (eval, js, cookies were dispatched without scope checks). tokenInfo flows through handleMetaCommand into the chain handler. Rejects entire chain if any subcommand fails. 2. /health strips sensitive fields (currentUrl, agent.currentMessage, session) when tunnel is active. Only operational metadata (status, mode, uptime, tabs) exposed to the internet. Previously anyone reaching the ngrok URL could surveil browsing activity. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: tout /pair-agent as headline feature in CHANGELOG + README Lead with what it does for the user: type /pair-agent, paste into your other agent, done. First time AI agents from different companies can coordinate through a shared browser with real security boundaries. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: expand /pair-agent, /design-shotgun, /design-html in README Each skill gets a real narrative paragraph explaining the workflow, not just a table cell. design-shotgun: visual exploration with taste memory. design-html: production HTML with Pretext computed layout. pair-agent: cross-vendor AI agent coordination through shared browser. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor: split handleCommand into handleCommandInternal + HTTP wrapper Chain subcommands now route through handleCommandInternal for full security enforcement (scope, domain, tab ownership, rate limiting, content wrapping). Adds recursion guard for nested chains, rate-limit exemption for chain subcommands, and activity event suppression (1 event per chain, not per sub). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: add content-security.ts with datamarking, envelope, and filter hooks Four-layer prompt injection defense for pair-agent browser sharing: - Datamarking: session-scoped watermark for text exfiltration detection - Content envelope: trust boundary wrapping with ZWSP marker escaping - Content filter hooks: extensible filter pipeline with warn/block modes - Built-in URL blocklist: requestbin, pipedream, webhook.site, etc. BROWSE_CONTENT_FILTER env var controls mode: off|warn|block (default: warn) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: centralize content wrapping in handleCommandInternal response path Single wrapping location replaces fragmented per-handler wrapping: - Scoped tokens: content filters + datamarking + enhanced envelope - Root tokens: existing basic wrapping (backward compat) - Chain subcommands exempt from top-level wrapping (wrapped individually) - Adds 'attrs' to PAGE_CONTENT_COMMANDS (ARIA value exposure defense) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: hidden element stripping for scoped token text extraction Detects CSS-hidden elements (opacity, font-size, off-screen, same-color, clip-path) and ARIA label injection patterns. Marks elements with data-gstack-hidden, extracts text from a clean clone (no DOM mutation), then removes markers. Only active for scoped tokens on text command. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: snapshot split output format for scoped tokens Scoped tokens get a split snapshot: trusted @refs section (for click/fill) separated from untrusted web content in an envelope. Ref names truncated to 50 chars in trusted section. Root tokens unchanged (backward compat). Resume command also uses split format for scoped tokens. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: add SECURITY section to pair-agent instruction block Instructs remote agents to treat content inside untrusted envelopes as potentially malicious. Lists common injection phrases to watch for. Directs agents to only use @refs from the trusted INTERACTIVE ELEMENTS section, not from page content. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test: add 4 prompt injection test fixtures - injection-visible.html: visible injection in product review text - injection-hidden.html: 7 CSS hiding techniques + ARIA injection + false positive - injection-social.html: social engineering in legitimate-looking content - injection-combined.html: all attack types + envelope escape attempt Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test: comprehensive content security tests (47 tests) Covers all 4 defense layers: - Datamarking: marker format, session consistency, text-only application - Content envelope: wrapping, ZWSP marker escaping, filter warnings - Content filter hooks: URL blocklist, custom filters, warn/block modes - Instruction block: SECURITY section content, ordering, generation - Centralized wrapping: source-level verification of integration - Chain security: recursion guard, rate-limit exemption, activity suppression - Hidden element stripping: 7 CSS techniques, ARIA injection, false positives - Snapshot split format: scoped vs root output, resume integration Also fixes: visibility:hidden detection, case-insensitive ARIA pattern matching. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: pair-agent skill compliance + fix all 16 pre-existing test failures Root cause: pair-agent was added without completing the gen-skill-docs compliance checklist. All 16 failures traced back to this. Fixes: - Sync package.json version to VERSION (0.15.9.0) - Add "(gstack)" to pair-agent description for discoverability - Add pair-agent to Codex path exception (legitimately documents ~/.codex/) - Add CLI_COMMANDS (status, pair-agent, tunnel) to skill parser allowlist - Regenerate SKILL.md for all hosts (claude, codex, factory, kiro, etc.) - Update golden file baselines for ship skill - Fix relink tests: pass GSTACK_INSTALL_DIR to auto-relink calls so they use the fast mock install instead of scanning real ~/.claude/skills/gstack Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: bump version and changelog (v0.15.12.0) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: E2E exit reason precedence + worktree prune race condition Two fixes for E2E test reliability: 1. session-runner.ts: error_max_turns was misclassified as error_api because is_error flag was checked before subtype. Now known subtypes like error_max_turns are preserved even when is_error is set. The is_error override only applies when subtype=success (API failure). 2. worktree.ts: pruneStale() now skips worktrees < 1 hour old to avoid deleting worktrees from concurrent test runs still in progress. Previously any second test execution would kill the first's worktrees. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: restore token in /health for localhost extension auth The CSO security fix stripped the token from /health to prevent leaking when tunneled. But the extension needs it to authenticate on localhost. Now returns token only when not tunneled (safe: localhost-only path). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test: verify /health token is localhost-only, never served through tunnel Updated tests to match the restored token behavior: - Test 1: token assignment exists AND is inside the !tunnelActive guard - Test 1b: tunnel branch (else block) does not contain AUTH_TOKEN Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: add security rationale for token in /health on localhost Explains why this is an accepted risk (no escalation over file-based token access), CORS protection, and tunnel guard. Prevents future CSO scans from stripping it without providing an alternative auth path. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: verify tunnel is alive before returning URL to pair-agent Root cause: when ngrok dies externally (pkill, crash, timeout), the server still reports tunnelActive=true with a dead URL. pair-agent prints an instruction block pointing at a dead tunnel. The remote agent gets "endpoint offline" and the user has to manually restart everything. Three-layer fix: - Server /pair endpoint: probes tunnel URL before returning it. If dead, resets tunnelActive/tunnelUrl and returns null (triggers CLI restart). - Server /tunnel/start: probes cached tunnel before returning already_active. If dead, falls through to restart ngrok automatically. - CLI pair-agent: double-checks tunnel URL from server before printing instruction block. Falls through to auto-start on failure. 4 regression tests verify all three probe points + CLI verification. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: add POST /batch endpoint for multi-command batching Remote agents controlling GStack Browser through a tunnel pay 2-5s of latency per HTTP round-trip. A typical "navigate and read" takes 4 sequential commands = 10-20 seconds. The /batch endpoint collapses N commands into a single HTTP round-trip, cutting a 20-tab crawl from ~60s to ~5s. Sequential execution through the full security pipeline (scope, domain, tab ownership, content wrapping). Rate limiting counts the batch as 1 request. Activity events emitted at batch level, not per-command. Max 50 commands per batch. Nested batches rejected. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test: add source-level security tests for /batch endpoint 8 tests verifying: auth gate placement, scoped token support, max command limit, nested batch rejection, rate limiting bypass, batch-level activity events, command field validation, and tabId passthrough.

Fixes check-freshness CI. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor: checkTabAccess uses options object, add own-only tab policy Refactors checkTabAccess(tabId, clientId, isWrite) to use an options object { isWrite?, ownOnly? }. Adds tabPolicy === 'own-only' support in the server command dispatch — scoped tokens with this policy are restricted to their own tabs for all commands, not just writes. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: add --domain flag to pair-agent CLI for domain restrictions Allows passing --domain to pair-agent to restrict the remote agent's navigation to specific domains (comma-separated). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * revert: remove batch commands CHANGELOG entry and VERSION bump The batch endpoint work belongs on the browser-batch-multitab branch (port-louis), not this branch.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: adopt main's headed-mode /health token serving Our merge kept the old !tunnelActive guard which conflicted with main's security-audit-r2 tests that require no currentUrl/currentMessage in /health.

Garry Tan	7665adf4fe	feat: headed mode + sidebar agent + Chrome extension (v0.12.0) (#517) ... * feat: CDP connect — control real Chrome/Comet via Playwright Add `connectCDP()` to BrowserManager: connects to a running browser via Chrome DevTools Protocol. All existing browse commands work unchanged through Playwright's abstraction layer. - chrome-launcher.ts: browser discovery, CDP probe, auto-relaunch with rollback - browser-manager.ts: connectCDP(), mode guards (close/closeTab/recreateContext/handoff), auto-reconnect on browser restart, getRefMap() for extension API - server.ts: CDP branch in start(), /health gains mode field, /refs endpoint, idle timer only resets on /command (not passive endpoints) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: browse connect/disconnect/focus CLI commands - connect: pre-server command that discovers browser, starts server in CDP mode - disconnect: drops CDP connection, restarts in headless mode - focus: brings browser window to foreground via osascript (macOS) - status: now shows Mode: cdp | launched | headed - startServer() accepts extra env vars for CDP URL/port passthrough Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: CDP-aware skill templates — skip cookie import in real browser mode Skills now check `$B status` for CDP mode and skip: - /qa: cookie import prompt, user-agent override, headless workarounds - /design-review: cookie import for authenticated pages - /setup-browser-cookies: returns "not needed" in CDP mode Regenerated SKILL.md files from updated templates. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: activity streaming — SSE endpoint for Chrome extension Side Panel Real-time browse command feed via Server-Sent Events: - activity.ts: ActivityEntry type, CircularBuffer (capacity 1000), privacy filtering (redacts passwords, auth tokens, sensitive URL params), cursor-based gap detection, async subscriber notification - server.ts: /activity/stream SSE, /activity/history REST, handleCommand instrumented with command_start/command_end events - 18 unit tests for filterArgs privacy, emitActivity, subscribe lifecycle Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: Chrome extension Side Panel + Conductor API proposal Chrome extension (Manifest V3, sideload): - Side Panel with live activity feed, @ref overlays, dark terminal aesthetic - Background worker: health polling, SSE relay, ref fetching - Popup: port config, connection status, side panel launcher - Content script: floating ref panel with @ref badges Conductor API proposal (docs/designs/CONDUCTOR_SESSION_API.md): - SSE endpoint for full Claude Code session mirroring in Side Panel - Discovery via HTTP endpoint (not filesystem — extensions can't read files) TODOS.md: add $B watch, multi-agent tabs, cross-platform CDP, Web Store publishing. Mark CDP mode as shipped. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: detect Conductor runtime, skip osascript quit for sandboxed apps macOS App Management blocks Electron apps (Conductor) from quitting other apps via osascript. Now detects the runtime environment: - terminal/claude-code/codex: can manage apps freely - conductor: prints manual restart instructions + polls for 60s detectRuntime() checks env vars and parent process. When Chrome needs restart but we can't quit it, prints step-by-step instructions and waits for the user to restart Chrome with --remote-debugging-port. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: detect Conductor via actual env vars (CONDUCTOR_WORKSPACE_NAME) Previous detection checked CONDUCTOR_WORKSPACE_ID which doesn't exist. Conductor sets CONDUCTOR_WORKSPACE_NAME, CONDUCTOR_BIN_DIR, CONDUCTOR_PORT, and __CFBundleIdentifier=com.conductor.app. Check these FIRST because Conductor sessions also have ANTHROPIC_API_KEY (which was matching claude-code). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: connection status pill — floating indicator when gstack controls Chrome Small pill in bottom-right corner of every page: "● gstack · 3 refs" Shows when connected via CDP, fades to 30% opacity after 3s, full on hover. Disappears entirely when disconnected. Background worker now notifies content scripts on connect/disconnect state changes so the pill appears/disappears without polling. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: Chrome requires --user-data-dir for remote debugging Chrome refuses --remote-debugging-port without an explicit --user-data-dir. Add userDataDir to BrowserBinary registry (macOS Application Support paths) and pass it in both auto-launch and manual restart instructions. Fix double-quoting in CLI manual restart instructions. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: Chrome must be fully quit before launching with --remote-debugging-port Chrome refuses to enable CDP on its default profile when another instance is running (even with explicit --user-data-dir). The only reliable path: fully quit Chrome first, then relaunch with the flag. Updated instructions to emphasize this clearly with verification step. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: bin/chrome-cdp — quit Chrome and relaunch with CDP in one command Quits Chrome gracefully, waits for full exit, relaunches with --remote-debugging-port, polls until CDP is ready. Usage: chrome-cdp [port] Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: use Playwright channel:chrome instead of broken connectOverCDP Playwright's connectOverCDP hangs with Chrome 146 due to CDP protocol version mismatch. Switch to channel:'chrome' which uses Playwright's native pipe protocol to launch the system Chrome binary directly. This is simpler and more reliable: - No CDP port discovery needed - No --remote-debugging-port or --user-data-dir hassles - $B connect just works — launches real Chrome headed window - All Playwright APIs (snapshot, click, fill) work unchanged bin/chrome-cdp updated with symlinked profile approach (kept for manual CDP use cases, but $B connect no longer needs it). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: green border + gstack label on controlled Chrome window Injects a 2px green border and small "gstack" label on every page loaded in the controlled Chrome window via context.addInitScript(). Users can instantly tell which Chrome window Claude controls. Also fixes close() for channel:chrome mode (uses browser.close() not browser.disconnect() which doesn't exist).

Updated command reference table, key components, env vars, source map. README.md: updated /browse description, added "Real browser mode" to What's New section. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: step-by-step Chrome extension install guide in BROWSER.md Replace terse bullet points with numbered walkthrough covering: developer mode toggle, load unpacked, macOS file picker tip (Cmd+Shift+G), pin extension, configure port, open side panel. Added troubleshooting section. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: add Cmd+Shift+. tip for hidden folders in macOS file picker macOS hides folders starting with . by default. Added both shortcuts: Cmd+Shift+G (paste path directly) and Cmd+Shift+. (show hidden files). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: integrate hidden folder tips into the install flow naturally Move Cmd+Shift+G and Cmd+Shift+. tips inline with the file picker step instead of as a separate tip block after it. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: auto-load Chrome extension when $B connect launches Chrome Extension auto-loads via --load-extension flag — no manual chrome://extensions install needed. findExtensionPath() checks repo root, global install, and dev paths. Also adds bin/gstack-extension helper for manual install in regular Chrome, and rewrites BROWSER.md install docs with auto-load as primary path. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: /connect-chrome skill — one command to launch Chrome with Side Panel New skill that runs $B connect, verifies the connection, guides the user to open the Side Panel, and demos the live activity feed. Extension auto-loads via --load-extension so no manual chrome://extensions install needed. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: use launchPersistentContext for Chrome extension loading Playwright's chromium.launch() silently ignores --load-extension. Switch to launchPersistentContext with ignoreDefaultArgs to remove --disable-extensions flag. Use bundled Chromium (real Chrome blocks unpacked extensions). Fixed port 34567 for CDP mode so the extension auto-connects. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: sync extension to DESIGN.md — amber accent, zinc neutrals, grain texture Import design system from gstack-website. Update all extension colors: green (#4ade80) → amber (#F59E0B/#FBBF24), zinc gray neutrals, grain texture overlay. Regenerate icons as amber "G" monogram on dark background. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: sidebar chat with Claude Code — icon opens side panel directly Replace popup flyout with direct side panel open on icon click. Primary UI is now a chat interface that sends messages to Claude Code via file queue. Activity/Refs tabs moved behind a debug toggle in the footer. Command bar with history, auto-poll for responses, amber design system. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: sidebar agent — Claude-powered chat backend via file queue Add /sidebar-command, /sidebar-response, and /sidebar-chat endpoints to the browse server. sidebar-agent.ts watches the command queue file, spawns claude -p with browse context for each message, and streams responses back to the sidebar chat. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: remove duplicate gstack pill overlay, hide crash restore bubble The addInitScript indicator and the extension's content script were both injecting bottom-right pills, causing duplicates. Remove the pill from addInitScript (extension handles it). Replace --restore-last-session with --hide-crash-restore-bubble to suppress the "Chromium didn't shut down correctly" dialog. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: state file authority — CDP server cannot be silently replaced Hardens the connect/disconnect lifecycle: - ensureServer() refuses to auto-start headless when CDP server is alive - $B connect does full cleanup: SIGTERM → 2s → SIGKILL, profile locks, state - shutdown() cleans Chromium SingletonLock/Socket/Cookie files - uncaughtException/unhandledRejection handlers do emergency cleanup This prevents the bug where a headless server overwrites the CDP server's state file, causing $B commands to hit the wrong browser. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: sidebar agent streaming events + session state management Enhance sidebar-agent.ts with: - Live streaming of claude -p events (tool_use, text, result) to sidebar - Session state file for BROWSE_STATE_FILE propagation to claude subprocess - Improved logging (stderr, exit codes, event types) - stdin.end() to prevent claude waiting for input - summarizeToolInput() with path shortening for compact sidebar display Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: sidebar chat UI — streaming events, agent status, reconnect retry Sidebar panel improvements: - Chat tab renders streaming agent events (tool_use, text, result) - Thinking dots animation while agent processes - Agent error display with styled error blocks - tryConnect() with 2s retry loop for initial connection - Debug tabs (Activity/Refs) hidden behind gear toggle - Clear chat button - Compact tool call display with path shortening Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: server-integrated sidebar agent with sessions and message queue Move the sidebar agent from a separate bun process into server.ts: - Agent spawns claude -p directly when messages arrive via /sidebar-command - In-memory chat buffer backed by per-session chat.jsonl on disk - Session manager: create, load, persist, list sessions - Message queue (cap 5) with agent status tracking (idle/processing/hung) - Stop/kill endpoints with queue dismiss support - /health now returns agent status + session info - All sidebar endpoints require Bearer auth - Agent killed on server shutdown - 120s timeout detects hung claude processes Eliminates: file-queue polling, separate sidebar-agent.ts process, stale auth tokens, state file conflicts between processes. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: extension auth + token flow for server-integrated agent Update Chrome extension to use Bearer auth on all sidebar endpoints: - background.js captures auth token from /health, exposes via getToken msg - background.js sets openPanelOnActionClick for direct side panel access - sidepanel.js gets token from background, sends in all fetch headers - Health broadcasts include token so sidebar auto-authenticates - Removes popup from manifest — icon click opens side panel directly Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: self-healing sidebar — reconnect banner, state machine, copy button Sidebar UI now handles disconnection gracefully: - Connection state machine: connected → reconnecting → dead - Amber pulsing banner during reconnect (2s retry, 30 attempts) - Red "Server offline" banner with Reconnect + Copy /connect-chrome buttons - Green "Reconnected" toast that fades after 3s on successful reconnect - Copy button lets user paste /connect-chrome into any Claude Code session Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: crash handling — save session, kill agent, distinct exit codes Hardened shutdown/crash behavior: - Browser disconnect exits with code 2 (distinct from crash code 1) - emergencyCleanup kills agent subprocess and saves session state - Clean shutdown saves session before exit (chat history persists) - Clear user message on browser disconnect: "Run $B connect to reconnect" Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: worktree-per-session isolation for sidebar agent Each sidebar session gets an isolated git worktree so the agent's file operations don't conflict with the user's working directory: - createWorktree() creates detached HEAD worktree in ~/.gstack/worktrees/ - Falls back to main cwd for non-git repos or on creation failure - Handles collision cleanup from prior crashes - removeWorktree() cleans up on session switch and shutdown - worktreePath persisted in session.json Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(qa): ISSUE-001 — disconnect blocked by CDP guard in ensureServer $B disconnect was routed through ensureServer() which refused to start a headless server when a CDP state file existed. Disconnect is now handled before ensureServer() (like connect), with force-kill + cleanup fallback when the CDP server is unresponsive. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: resolve claude binary path for daemon-spawned agent The browse server runs as a daemon and may not inherit the user's shell PATH. Add findClaudeBin() that checks ~/.local/bin/claude (standard install location), which claude, and common system paths. Shows a clear error in the sidebar chat if claude CLI is not found. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: resolve claude symlinks + check Conductor bundled binary posix_spawn fails on symlinks in compiled bun binaries. Now: - Checks Conductor app's bundled binary first (not a symlink) - Scans ~/.local/share/claude/versions/ for direct versioned binaries - Uses fs.realpathSync() to resolve symlinks before spawning Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: compiled bun binary cannot posix_spawn — use external agent process Compiled bun binaries fail posix_spawn on ALL executables (even /bin/bash). The server now writes to an agent queue file, and a separate non-compiled bun process (sidebar-agent.ts) reads the queue, spawns claude, and POSTs events back via /sidebar-agent/event. Changes: - server.ts: spawnClaude writes to queue file instead of spawning directly - server.ts: new /sidebar-agent/event endpoint for agent → server relay - server.ts: fix result event field name (event.text vs event.result) - sidebar-agent.ts: rewritten to poll queue file, relay events via HTTP - cli.ts: $B connect auto-starts sidebar-agent as non-compiled bun process Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: loading spinner on sidebar open while connecting to server Shows an amber spinner with "Connecting..." when the sidebar first opens, replacing the empty state. After the first successful /sidebar-chat poll: - If chat history exists: renders it immediately - If no history: shows the welcome message Prevents the jarring empty-then-populated flash on sidebar open. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: zero-friction side panel — auto-open on install, pill is clickable Three changes to eliminate manual side panel setup: - Auto-open side panel on extension install/update (onInstalled listener) - gstack pill (bottom-right) is now clickable — opens the side panel - Pill has pointer-events: auto so clicks always register (was: none) User no longer needs to find the puzzle piece icon, pin the extension, or know the side panel exists. It opens automatically on first launch and can be re-opened by clicking the floating gstack pill. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor: kill CDP naming, delete chrome-launcher.ts dead code The connectCDP() method and connectionMode: 'cdp' naming was a legacy artifact — real Chrome was tried but failed (silently blocks --load-extension), so the implementation already used Playwright's bundled Chromium via launchPersistentContext(). The naming was misleading. Changes: - Delete chrome-launcher.ts (361 LOC) — only import was in unreachable attemptReconnect() method - Delete dead attemptReconnect() and reconnecting field - Delete preExistingTabIds (was for protecting real Chrome tabs we never connect to) - Rename connectCDP() → launchHeaded() - Rename connectionMode: 'cdp' → 'headed' across all files - Replace BROWSE_CDP_URL/BROWSE_CDP_PORT env vars with BROWSE_HEADED=1 - Regenerate SKILL.md files for updated command descriptions - Move BrowserManager unit tests to browser-manager-unit.test.ts Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: converge handoff into connect — extension loads on handoff Handoff now uses launchPersistentContext() with extension auto-loading, same as the connect/launchHeaded() path. This means when the agent gets stuck (2FA, CAPTCHA) and hands off to the user, the Chrome extension + side panel are available automatically. Before: handoff used chromium.launch() + newContext() — no extension After: handoff uses chromium.launchPersistentContext() — extension loads Also sets connectionMode to 'headed' and disables dialog auto-accept on handoff, matching connect behavior. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: gate sidebar chat behind --chat flag $B connect (default): headed Chromium + extension with Activity + Refs tabs only. No separate agent spawned. Clean, no confusion. $B connect --chat: same + Chat tab with standalone claude -p agent. Shows experimental banner: "Standalone mode — this is a separate agent from your workspace." Implementation: - cli.ts: parse --chat, set BROWSE_SIDEBAR_CHAT env, conditionally spawn sidebar-agent - server.ts: gate /sidebar-* routes behind chatEnabled, return 403 when disabled, include chatEnabled in /health response - sidepanel.js: applyChatEnabled() hides/shows Chat tab + banner - background.js: forward chatEnabled from health response - sidepanel.html/css: experimental banner with amber styling Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: file drop relay + $B inbox command Sidebar agent now writes structured messages to .context/sidebar-inbox/ when processing user input. The workspace agent can read these via $B inbox to see what the user reported from the browser. File drop format: .context/sidebar-inbox/{timestamp}-observation.json { type, timestamp, page: {url}, userMessage, sidebarSessionId } Atomic writes (tmp + rename) prevent partial reads. $B inbox --clear removes messages after display. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: $B watch — passive observation mode Claude enters read-only mode and captures periodic snapshots (every 5s) while the user browses. Mutation commands (click, fill, etc.) are blocked during watch. $B watch stop exits and returns a summary with the last snapshot. Requires headed mode ($B connect). This is the inverse of the scout pattern — the workspace agent watches through the browser instead of the sidebar relaying to it. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test: add coverage for sidebar-agent, file-drop, and watch mode 33 new tests covering: - Sidebar agent queue parsing (valid/malformed/empty JSONL) - writeToInbox file drop (directory creation, atomic writes, JSON format) - Inbox command (display, sorting, --clear, malformed file handling) - Watch mode state machine (start/stop cycles, snapshots, duration) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: TODOS cleanup + Chrome vs Chromium exploration doc - Update TODOS.md: mark CDP mode, $B watch, sidebar scout as SHIPPED - Delete dead "cross-platform CDP browser discovery" TODO - Rename dependencies from "CDP connect" to "headed mode" - Add docs/designs/CHROME_VS_CHROMIUM_EXPLORATION.md memorializing the architecture exploration and decision to use Playwright Chromium Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: add Conductor Chrome sidebar integration design doc Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: sidebar-agent validates cwd before spawning claude The queue entry may reference a worktree that was cleaned up between sessions. Now falls back to process.cwd() if the path doesn't exist, preventing silent spawn failures. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: gen-skill-docs resolver merge + preamble tier gate + plan file discovery The local RESOLVERS record in gen-skill-docs.ts was shadowing the imported canonical resolvers, causing stale test coverage and preamble generators to be used instead of the authoritative versions in resolvers/. Changes: - Merge imported RESOLVERS with local overrides (spread + override pattern) - Fix preamble tier gate: tier 1 skills no longer get AskUserQuestion format - Make plan file discovery host-agnostic (search multiple plan dirs) - Add missing E2E tier entries for ship/review plan completion tests Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: ungate sidebar agent + raise timeout to 5 minutes (v0.12.0) Sidebar chat is now always available in headed mode — no --chat flag needed. Agent tasks get 5 minutes instead of 2, enabling multi-page workflows like navigating directories and filling forms across pages. Changes: - cli.ts: remove --chat flag, always set BROWSE_SIDEBAR_CHAT=1, always spawn agent - server.ts: remove chatEnabled gate (403 response), raise AGENT_TIMEOUT_MS to 300s - sidebar-agent.ts: raise child process timeout from 120s to 300s Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: headed mode + sidebar agent documentation (v0.12.0) - README: sidebar agent section, personal automation example (school parent portal), two auth paths (manual login + cookie import), DevTools MCP mention - BROWSER.md: sidebar agent section with usage, timeout, session isolation, authentication, and random delay documentation - connect-chrome template: add sidebar chat onboarding step - CHANGELOG: v0.12.0 entry covering headed mode, sidebar agent, extension - VERSION: bump to 0.12.0.0 - TODOS: Chrome DevTools MCP integration as P0 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: regenerate SKILL.md files Generated from updated templates + resolver merge. Key changes: - Tier 1 skills no longer include AskUserQuestion format section - Ship/review skills now include coverage gate with thresholds - Connect-chrome skill includes sidebar chat onboarding step - Plan file discovery uses host-agnostic paths Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: regenerate Codex connect-chrome skill Updated preamble with proactive prompt and sidebar chat onboarding step. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: network idle, state persistence, iframe support, chain pipe format (v0.12.1.0) (#516) * feat: network idle detection + chain pipe format - Upgrade click/fill/select from domcontentloaded to networkidle wait (2s timeout, best-effort). Catches XHR/fetch triggered by interactions. - Add pipe-delimited format to chain as JSON fallback: $B chain 'goto url | click @e5 | snapshot -ic' - Add post-loop networkidle wait in chain when last command was a write. - Frame-aware: commands use target (getActiveFrameOrPage) for locator ops, page-only ops (goto/back/forward/reload) guard against frame context. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: $B state save/load + $B frame — new browse commands - state save/load: persist cookies + URLs to .gstack/browse-states/{name}.json File perms 0o600, name sanitized to [a-zA-Z0-9_-]. V1 skips localStorage (breaks on load-before-navigate). Load replaces session via closeAllPages(). - frame: switch command context to iframe via CSS selector, @ref, --name, or --url. 'frame main' returns to main frame. Execution target abstraction (getActiveFrameOrPage) across read-commands, snapshot, and write-commands. - Frame context cleared on tab switch, navigation, resume, and handoff. - Snapshot shows [Context: iframe src="..."] header when in frame. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test: add tests for network idle, chain pipe format, state, and frame - Network idle: click on fetch button waits for XHR, static click is fast - Chain pipe: pipe-delimited commands, quoted args, JSON still works - State: save/load round-trip, name sanitization, missing state error - Frame: switch to iframe + back, snapshot context header, fill in frame, goto-in-frame guard, usage error New fixtures: network-idle.html (fetch + static buttons), iframe.html (srcdoc) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: review fixes — iframe ref scoping, detached frame recovery, state validation - snapshot.ts: ref locators, cursor-interactive scan, and cursor locator now use target (frame-aware) instead of page — fixes @ref clicking in iframes - browser-manager.ts: getActiveFrameOrPage auto-recovers from detached frames via isDetached() check - meta-commands.ts: state load resets activeFrame, elementHandle disposed after contentFrame(), state file schema validation (cookies + pages arrays), filter empty pipe segments in chain tokenizer - write-commands.ts: upload command uses target.locator() for frame support Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: regenerate SKILL.md files + rebuild binary Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: bump version and changelog (v0.12.1.0) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-26 11:15:24 -06:00
Garry Tan	d7c732b282	fix: Windows support — Node.js server fallback for Playwright (#255) ... * fix: Windows support — Node.js server fallback for Playwright Setup hangs on Windows 11 because Bun's child_process can't handle Playwright's --remote-debugging-pipe (fd 3/4 pipe handles). Fall back to Node.js on Windows for both the setup verification and server runtime. macOS/Linux completely unaffected — all Windows code behind IS_WINDOWS / process.platform === 'win32' guards. Based on community PR #194 by @sozairali. Fixed sed -i portability (perl -pi -e) in build-node-server.sh for macOS compatibility. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: cross-platform path handling for Windows compatibility Replace hardcoded '/tmp' and 'dir + "/"' path checks with platform-aware constants from new platform.ts module.
