Garry Tan	008dd65b1f	v1.64.0.0 fix wave: full tracker audit — 90 fixes, 52 issues closed, ~50 community PRs absorbed (#2571) ... * fix(hooks): nest freeze/careful permissionDecision under hookSpecificOutput Claude Code ignores a top-level permissionDecision, so the /freeze deny and /careful ask guards silently allowed everything. Nest both under hookSpecificOutput with permissionDecisionReason, update the shape-blind tests to pin the nested form, and document the constraint in both skill templates (regen included). Closes half of #1459 (freeze enforcement chain). Contributed by @jawadakram20 (PR #2331; team-init hunk deferred to the dedicated team-init fix). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(team-init): required-mode hook blocks with nested schema + exit 2 The generated check-gstack.sh emitted a flat permissionDecision payload and exited 0, which Claude Code ignores — required mode enforced nothing. The generated hook now nests the deny under hookSpecificOutput and exits 2 so the block holds even if the JSON schema drifts again. Adds a temp-repo regression test that runs the generated hook under both installed and missing-gstack homes. Fixes #2413, #2296. Contributed by @Masashi-Ono0611 (PR #2423). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(careful): close three check-careful bypasses via real JSON extraction The grep-based command extractor stopped at the first escaped quote, so any quoted argument truncated the command before the pattern checks ran — `git commit -m "wip" && rm -rf /` was silently allowed. Replace it with a python3/node JSON parse that fails CLOSED on unreadable payloads, add an IFS/base64-to-shell obfuscation tripwire, and stop multi-line commands from riding the single-line safe-exception whitelist (line-based grep would have approved `rm -rf /` when a later line matched node_modules — a hazard the real newline decoding exposed). Contributed by @wtamminga (PR #2426; the -R hunk was dropped — it landed in v1.61.0.0 — and output shapes updated to the nested hookSpecificOutput form). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(review,autoplan): require explicit run_in_background: false on specialist agents Claude Code v2.1.198 made subagents run in the background by default, which inverted the old "do not use the flag" guidance: review-army specialists and autoplan dual voices silently launched in the background and the merge step could proceed before they completed — regressing the #497 fix. The generated guidance now instructs an explicit run_in_background: false, and a static tripwire fails the free suite if the inert inverted phrasing ever returns to any generated SKILL.md. Fixes #2440. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(investigate): anchor the scope-lock freeze hook on $HOME, not CLAUDE_SKILL_DIR The investigate skill's PreToolUse hooks and Scope Lock probe resolved check-freeze.sh via ${CLAUDE_SKILL_DIR}, which does not exist when frontmatter hooks run — the || exit 0 tail then failed open, so the debug scope boundary silently never engaged (#1871 follow-up). Anchor all four sites on $HOME/.claude/skills/gstack/ like careful/freeze, and add a static test asserting no frontmatter command: line in the guard-family skills ever references CLAUDE_SKILL_DIR again. Fixes #2469; closes the last live half of #1459 together with the freeze/careful hookSpecificOutput fix. The broader portable-install-root rewrite stays #1882 (its own focused PR per the TODOS.md decision). Reported with a fix by @maxpetrusenkoagent (PR #1873; absorbed narrowly — the cwd-walk rewrite belongs to #1882). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(redact): scan large diffs in line-aligned slices; stop digit-UUIDs matching as cards/phones The prepush guard blocked any push whose added lines exceeded the engine's 1 MiB cap with engine.input_too_large — a size error naming no credential — which trains people onto GSTACK_REDACT_PREPUSH=skip. Scan in 768 KiB line-aligned slices instead (no pattern is multi-line, so a boundary cannot bisect a secret); a single oversized line still goes to the engine intact and fails closed. Also suppress card/phone matches whose span sits ENTIRELY inside a UUID — digit-only UUID fixtures were 14 of 21 MEDIUM findings on an ordinary branch, the noise level that stops people reading MEDIUM at all. Fixes #2304. Contributed by @luckywenapere (PR #2543). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(redact): block Google OAuth client secrets and Telegram bot tokens at HIGH GOCSPX-prefixed client secrets and <bot_id>:<35-char> Telegram tokens are never-publishable credential shapes with unambiguous formats — both now block at HIGH like the other live-format credentials. Contributed by @francis-eye (PR #2357). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(redact-prepush): resolve the real push base instead of EMPTY_TREE whole-repo scans When the remote default branch is not main/master (or origin/HEAD is unset), the merge-base guess failed and the hook fell back to scanning the ENTIRE repository as added lines — re-attributing long-pushed secrets to the current push and, on any real repo, tripping the engine byte cap so the push blocked having scanned nothing. Derive the base from commits reachable from no remote-tracking branch, keep the empty-tree path only for genuinely fresh repos, and split the block message so an unscannable diff is reported as "could not scan (fail closed)" rather than "credential found — rotate it". Contributed by @stormeoio (PR #2398). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(redact-prepush): preserve the trailing newline handed to chained pre-push.local The chaining wrapper captured stdin with $(cat), which strips the trailing newline — a chained shell hook built on `while read` then never entered its loop for the final (usually only) ref line and exited 0, failing OPEN. Use the printf-x sentinel so the byte-exact input reaches the chained hook, with tests covering both the pass-through and the short-circuit paths. Contributed by @francis-eye (PR #2358). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(redact-prepush): close the ext-diff, header-lookalike, and ref-parse bypasses Three ways the pushed diff escaped scanning: (1) a user-level diff.external or textconv driver replaced the diff with its own output — zero '+' lines, so the scan saw nothing (now --no-ext-diff --no-textconv); (2) an added content line whose text begins with "++" renders as "+++…" and the blanket header skip dropped it (now hunk-aware header detection); (3) a pre-push ref line that failed to parse was silently skipped, leaving that ref unscanned (now fails closed with the offending line named). Minimal reimplementation of the two confirmed bypasses from PR #2498 by @lubosxyz (the full PR overlaps the chunked-scan work absorbed separately), plus the unparseable-ref hardening. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(pair-agent): keep the ngrok authtoken out of the transcript and shell argv The not-authed flow told the user to paste their ngrok authtoken into the chat so the agent could run `ngrok config add-authtoken` — putting a live credential in the transcript, tool-call argv, and anything the transcript syncs to. The user now runs the auth command in their own terminal; the agent only verifies via `ngrok config check`, and a pasted token triggers a rotate-and-reauth instruction. A static test pins that no agent-run bash fence ever contains add-authtoken again. Fixes #2335. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(update-check): crash emits CHECK_FAILED instead of reading as up-to-date gstack-update-check signals "up to date" with SILENCE, and it runs under set -e — so any unguarded mid-script failure exited quietly and was indistinguishable from a current install. Observed live as a 45-release silent-staleness incident. An ERR trap (with -E so it propagates into functions) now emits a CHECK_FAILED sentinel naming the line and status, and exits 0 so caller `|| true` guards can't eat it. Behavioral tests cover both the crash and the healthy-silent paths; egress-receipt wiring is untouched and still pinned by test/egress-receipt-wiring.test.ts. Fixes #1974. (#2378's HEAD-SHA staleness half was already fixed on main by the ls-remote + SHA-pinned VERSION resolution — close as already-fixed.) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(deps): bump diff 7.0.0 → 9.0.0 (GHSA-73rr-hh4g-fpgx parsePatch DoS) The advisory affects diff 6.x–8.0.2. The only API this repo uses is Diff.diffLines (browse/src/snapshot.ts:571, browse/src/meta-commands.ts:728), which is unchanged across the major hop; snapshot tests pass against 9.0.0. Closes #1588. Contributed by @genisis0x (PR #1599; VERSION collateral stripped, lockfile regenerated fresh). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * ci(evals): skip eval jobs deterministically on fork PRs Fork PRs never receive repository secrets, so every API-calling eval failed at SDK auth — but only when Docker-cache luck let the jobs start at all, making fork PRs randomly red or grey. Skip the eval and report jobs explicitly for fork-origin PRs, keep the image BUILD (validates Dockerfile.ci changes) without the push a fork token can't perform, and leave full coverage for same-repo PRs, pushes, and dispatches. Contributed by @andrey-esipov (PR #2345). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(extension): deny token/port reads to content-script and foreign senders background.js answered getPort — port, connected state, AND the browse server auth token — to any sender that passed the type allowlist, including content scripts running in web-page context and, behind only the sender.id check, anything without extension-page provenance. The getToken sender.tab restriction covered getToken alone, and only after getPort had already handed out the token. Single decision point now: extension/sender-auth.js classifies each message type; the eight privileged types (getPort, setPort, getServerUrl, getToken, fetchRefs, command, sidebar-command, getTabState) require an own-extension-page sender (chrome-extension://<own id>/ URL, no sender.tab, own sender.id). Denied senders get { error: 'unauthorized' } and nothing else — never the token, never the port. Content-script flows (elementPicked, pickerCancelled, inspectResult, openSidePanel) are untouched, and the sidepanel/popup keep the getPort token field their connect path reads. The policy mirrors the v1.63 server-side model: AUTH_TOKEN is released only to the pinned extension Origin via POST /extension-token, so the extension must not re-leak it to contexts the server would never have trusted. browse/test/extension-sender-auth.test.ts drives the real background.js onMessage listener under a chrome stub with four sender shapes (own extension page, own content script, foreign extension id, missing sender.url) and pins that denied responses carry no token/port fields, that a denied setPort never persists, that a denied command never reaches the network, and that the inspector + tab-state flows keep working. The helper is loaded via importScripts in the classic service worker and require()-able from bun tests. Contributed by @punksterlabs (PR #1822; reimplemented against the v1.63 POST /extension-token pinned-origin model). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(update-check): fixture links gstack-egress-lib.sh — all 38 tests failed on main v1.63.0.0 made bin/gstack-update-check source bin/gstack-egress-lib.sh unconditionally, but the test fixture's GSTACK_DIR only linked gstack-config — every test died at the source line (0/38 pass on pristine main, verified). The suite-truncation bug hid it: the runner was killed by an earlier file's delayed process.exit before this file ran. Link the lib like the real install layout the script assumes. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(browse): capture active-tab state before close() — last-tab auto-create raced the close event closeTab checked `tabId === this.activeTabId` AFTER awaiting page.close(), but the page 'close' event handler can fire during that await and reassign activeTabId — losing the race meant the last-tab auto-create never ran, leaving the manager with zero tabs. Capture wasActive before closing, and only reassign activeTabId when it no longer points at a live tab. Part of the test-integrity repairs unmasked by the suite-truncation fix. Contributed by @time-attack (PR #2230, browser-manager hunk). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(browse): delete the orphaned sidebar chat-queue suite; align sidebar-ux/tabs with the PTY-only sidebar browse/test/sidebar-integration.test.ts tested the /sidebar-command queue path ripped in v1.14 (34 references to removed endpoints — 11 permanent failures masked by suite truncation). sidebar-ux.test.ts carried 73 failures pinning the same dead surface (pickSidebarModel, ANALYSIS_WORDS); the trim keeps its 108 live tests, including the background.js token/allowlist gates. sidebar-tabs gets the two matching expectation updates. Closes #2420, #1980. Contributed by @time-attack (PR #2230, sidebar hunks; the security-sidepanel-dom deletion was NOT taken — that suite pins the live sidepanel DOM surface and passes). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(browse): align dual-listener and terminal-agent static guards with the current source Two static-grep guards pinned superseded source shapes and failed once the suite actually ran them: the tunnel dispatch gate is args-aware since the --out disk-write ban (canDispatchOverTunnel takes command AND args), and lazy PTY spawn routes through the maybeSpawnPty helper since v1.44. The updated assertions pin the current, stricter shapes (open() never spawns; the helper is the only spawnClaude caller). Contributed by @time-attack (PR #2230, dual-listener + terminal-agent hunks). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(test): remove all 8 delayed process.exit teardown bombs — the tier-1 gate can finally fail bun test runs every file in ONE process, so a 500ms setTimeout(process.exit(0)) armed in afterAll fired mid-way through a LATER file and killed the entire suite with exit 0 and no summary — only ~16 of 434 files ran, and every downstream failure was invisible (observed live throughout this wave's enumeration). Changes, all guarded by fault injection: - Replace every delayed-exit teardown with a time-boxed close of the file's own browser (8 files across browse/ and design/); stub the daemon /shutdown timer instead of letting its unconditional process.exit tear the runner down. - test/no-suicide-exit.test.ts: static tripwire — no *.test.ts may schedule a delayed process.exit again. - test/exit-propagation.test.ts + fixtures: fault injection with REAL bun output proves the truncation shape (exit 0, no summary) and that scripts/test-free-shards.ts now detects it: a shard exiting 0 WITHOUT bun's final summary line is treated as FAILED (exit code alone is not evidence of completion). - handoff: the three headed-mode integration tests are darwin-skipped with a pointer to the known macOS headed-launch breakage (#2242/#2554); they keep running on Linux CI. Un-skip in the browse-daemon wave. - feedback-roundtrip: repair the handler call sites unmasked by the fix — handlers take (command, args, session, bm); passing the manager where a session belongs broke all six tests. - user-slug-fallback: HOME isolation makes endpoint_hash deterministic. Fixes #2421, #2435. Contributed by @sneakygriff (PR #2172) with repairs from @time-attack (PR #2230 feedback-roundtrip hunks); supersedes PR #2252 by @whd4 (same defect, credited). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test: include design/test/ in the free suite and the sharded runner design/test was absent from both the package.json test globs and TEST_ROOTS in scripts/test-free-shards.ts — its tests (including one of the teardown bombs removed in the previous commit) never ran in any CI or local free run, so design fixes could ship without their unit tests executing. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(make-pdf): reject directories when resolving the browse binary access(X_OK) is true for directories (they carry the execute/traverse bit on POSIX and pass the Windows existence check too), so cwd-dependent resolution could pick the ~/.claude/skills/browse alias DIRECTORY as the browse binary. Every browse call then exited 4 with empty stderr, which make-pdf surfaced as "Chromium failed to launch" against a perfectly healthy Chromium (#2156). Guard isExecutable with statSync().isFile() so only regular files qualify. Contributed by @jwilk-hrep (PR #2538). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(make-pdf): write browse-bound temp files under the safe-dirs allowlist os.tmpdir() on macOS resolves to /var/folders/..., which fails browse's safe-dirs validation ([/tmp, cwd]) since the v1.6.0.0 --from-file tightening. Default PDF output (generate with no -o), the preview HTML, tmpFile() scratch files, and setup's smoke-test fixture/output all wrote there, so browse rejected the paths it was asked to read or write. Export PAYLOAD_TMP_DIR from browseClient (the existing TEMP_DIR convention: os.tmpdir() on Windows, /tmp elsewhere) and route orchestrator.ts and setup.ts temp files through it. Contributed by @lvthewah (PR #2505; the browse-binary directory guard from that PR landed separately via PR #2538). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(make-pdf): stop URLs swallowing smartypants placeholders A bare autolinked URL (<a href="X">X</a>) has zero whitespace between the URL text and its own closing tag. TAG_RE carves that </a> into a NUL-delimited SMARTPANTS_PRESERVED placeholder BEFORE the URL pass runs, and URL_RE's \S+ swallowed the adjacent placeholder into the URL match. The restore pass is single-shot, so the inner placeholder never restored: raw "SMARTPANTS_PRESERVED_N" text leaked into the rendered link, the </a> vanished, and link-blue styling bled into the rest of the document (#2084). Excluding the NUL sentinel (\u0000) from the URL character class stops the match from crossing into an already-carved zone. Contributed by @marshaung (PR #2280; PR #2339 by @BrendaB24 covered the same smartypants defect). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(make-pdf): no blank first page when content precedes the first H1 Two paths put invisible content ahead of the first H1 and cost users a blank page 1 (#1904): - A visually-empty preamble (leading <style> block, HTML comment) became its own .chapter. That section took the `.chapter:first-of-type { break-before: auto }` exception, so the first real chapter inherited `break-before: page` and started on page 2. Non-rendering preambles now fold into the first real chapter (markup preserved, no page break); real text preambles keep their own chapter. - Leading YAML frontmatter rendered as a literal paragraph of body text on its own first page (marked has no frontmatter awareness). It is now stripped before parsing; a `---` thematic break elsewhere is untouched. Contributed by @jbetala7 (PR #1913). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(browse): allow about:blank so a restarted daemon can initialise The daemon opens its own first tab on about:blank, so blocking it in validateNavigationUrl meant a restarted daemon could never recreate the blank tab it starts from — and `browse newtab about:blank`, which `make-pdf setup` runs as its Chromium smoke test, failed and surfaced as "Chromium failed to launch" against a healthy browser. Allow about:blank ONLY, never the about: scheme: about:blank has no origin, loads nothing and runs nothing, while about:config and friends are real surfaces. Exact href match (lower-cased, since the URL parser normalises the protocol but not the opaque part), so about:blankfoo stays blocked. Contributed by @jwilk-hrep (PR #2537). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(design): drop gpt-image-2 tool model that 400s under the gpt-4o orchestrator The Responses API rejects pairing a gpt-4o orchestrator with an image_generation tool spec'd as model: "gpt-image-2" (400 invalid_request_error), which took every design image call offline — generate, variants, iterate (both threaded and fresh paths), evolve, and /design-shotgun (#1771). gpt-image-2 is only valid under a gpt-5 orchestrator; with gpt-4o the tool must omit the model field (defaults to gpt-image-1). Remove the model field at all five call sites and add a static-grep tripwire test (design/test/image-gen-pairing.test.ts) that fails CI if any design/src module reintroduces the gpt-4o + gpt-image-2 pairing. Re-enabling gpt-image-2 later requires bumping the orchestrator off gpt-4o in the same diff, which the tripwire permits. Contributed by @Pablosinyores (PR #1773). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(design): variants AbortError message reports the real 240s timeout generateVariant arms its abort at 240_000 ms but the AbortError branch returned "Timeout (120s)" — off by 2x, so a user staring at the failure could not tell whether to bump the timeout, retry, or drop the call. Report the actual configured bound, and pin it with a test that forces the abort path (fast-forwarding only the 240_000 ms timer) and asserts the surfaced string matches. Contributed by @vryahn (PR #1774). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(memory-ingest): stop silently ingesting 0 pages — include gitignored staging, reconcile counts Pages stage into ~/.gstack/.staging-ingest-*/ inside a repo whose .gitignore is `*`, and gbrain import honours .gitignore — so it collected 0 files, imported nothing, and the ingest still reported "written: N" from the STAGED count while advancing state, meaning no future run ever retried. Three layers now: (1) pass --include-gitignored (root cause); (2) if the installed gbrain predates the flag, retry without it (subcommand --help is generic, so the attempt is the only probe) with an upgrade pointer; (3) reconcile gbrain's imported+unchanged accounting against the staged count and REFUSE to advance state on a shortfall, naming the gitignore collision. Fixes #2144, #2104. Contributed by @gawievanblerk (PR #2560) and @Charles-Grant (PR #2486). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(autoplan): task aggregator returned zero tasks on every run — jq scope bug Inside ($commits | split("|") | ...) the "." context is the split ARRAY, so the filter's bare .commit raised "Cannot index array with string" on every record — and the 2>/dev/null swallowed it, so aggregation silently produced zero tasks no matter how many the reviews emitted. Bind .commit to $c before the pipe. Reproduced live before the fix; regenerated autoplan/SKILL.md. Fixes #2018. Contributed by @kkroo (PR #2416; regenerated against the current template). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(session-update): un-wedge auto-upgrade — autostash over local patches, log the pull's real reason On a normal install the tracked files ARE locally patched (skill-prefix name rewrites, gbrain-refresh blocks), so the bare `git pull --ff-only` refused on every run and auto-upgrade froze forever — observed as 308 consecutive PULL_FAILED entries with the reason discarded by 2>/dev/null. Pull now runs --autostash (local patches ride over the update and pop back), stderr is captured into the log so a genuine failure names its cause, an autostash pop conflict recovers to a clean tree and re-renders the patches (gstack-patch-names + gbrain-refresh, both idempotent), and a successful pull re-renders them as a self-heal. Behavioral tests cover the wedge shape and the reason logging. Fixes #2566. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test: raise the free-suite per-test timeout to 30s bun's 5s default is fine for a file run solo, but the monolithic free suite shares one process across 100+ files whose browser instances contend for launch slots — Playwright tests that pass in isolation time out mid-suite. 30s matches the ceiling the enumeration runs used; the sharded runner (test:free) is unaffected. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(question-log): parse native AskUserQuestion answers — every native answer logged as __unknown__ Current Claude Code returns AskUserQuestion results as an OBJECT map keyed by question text ({answers: {question: label}}); the hook only handled the legacy array shapes, so 86% of live records carried user_choice __unknown__ — and the bin then scored every one as followed_recommendation false, silently poisoning plan-tune metrics. Adds the object-map extraction (exact + whitespace-normalized + single-question pairing, multiSelect joins, annotations as free_text), strips the (Recommended) suffix from BOTH sides of the comparison, skips the computation entirely on extraction failure, and logs unrecognized shapes to hook-errors.log instead of embedding them in the record. Fixes #2336, #2206. Based on the working patch in #2336 by @yijisoo; suffix comparison fix contributed by @chuchu2781 (PR #2400). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(slug): canonicalize slash branches to dash form — review history stops splitting Branch-name sanitization disagreed across gstack (four incompatible rules), so reviews for the same slash-named branch landed in multiple files and the ship dashboard missed entries. gstack-slug now canonicalizes / to - in one place, and ship's review lookup routes through it; goldens regenerated against the current templates. Fixes #1127, #2550. Contributed by @ShuratCode (PR #2465; duplicate fixes by @xrfael-dev and two others in PRs #1851/#1699/#1621, credited). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(slug): resolve the project root by marker walk-up — subdirectory sessions stop misfiling state gstack-slug derived everything from pwd, so a session in a subdirectory got the subdir's basename as its slug (or an outer monorepo's remote), misfiling reviews/decisions/learnings under a phantom project — and the per-pwd cache made the wrong answer permanent. The resolver now walks up from pwd: outermost STRONG marker wins (.git, package.json, pyproject.toml, Cargo.toml, Gemfile, go.mod, .project.yaml), weak content markers (README, LICENSE) catch non-code project folders, deploy artifacts are deliberately not markers, and GSTACK_PROJECT_SLUG remains the escape hatch. The cache self-heals on mismatch. Main-side invariants preserved on top: the unconditional [a-zA-Z0-9._-] re-sanitize before echo and slash→dash branch canonicalization. Fixes #1125. Contributed by @ajeenkya (PR #1702; rebased over the sanitize and branch-canonicalization work that landed after it). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(hooks): shared spawn-bin helper — all three AskUserQuestion hooks were inert on Windows The plan-tune hooks resolved bin scripts via new URL(import.meta.url).pathname (which doubles the drive letter on Windows: /C:/C:/...) and spawnSync'd extensionless bash scripts directly (unrunnable without a shell association) — so question logging, preferences, and the error fallback all silently no-op'd on Windows, and /plan-tune collected no data. A single spawn-bin.ts helper now owns bin resolution (fileURLToPath) and win32 bash routing for every hook, with static tripwires so a future hook can't reintroduce the raw pattern. This is the one Windows-spawn idiom for hook code. Fixes #2356. Contributed by @rafassousa (PR #2504; supersedes PR #2399 by @chuchu2781). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(model-overlays): add fable-5, opus-4-8, and sonnet-5 overlays + resolver mappings model-overlays/ had no entry for the current Claude generation, so every session on a Claude 5 family or Opus 4.8 model fell through to the generic claude.md nudges. Adds the three overlays with resolver mappings and per-overlay tests; generated output for the default host is unchanged (overlays activate by detected model). Closes #2509. Contributed by @chrisquorum (PRs #2246, #2243, #2247). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(windows): grant icacls ACEs by *SID, not unqualified username An unqualified username handed to icacls is ambiguous: on a machine whose hostname equals the username (a common Windows setup), it resolves to the MACHINE account instead of the user. Combined with /inheritance:r, that leaves ~/.gstack with a single ACE matching nobody — the process that just "secured" the directory locks itself out, and icacls still reports success. Both icacls sites in the repo (restrictFilePermissions and restrictDirectoryPermissions in browse/src/file-permissions.ts — the only icacls call sites; setup has none) now grant via icacls' literal-SID form `*<SID>`, resolved once per process from System32\whoami.exe (pinned to System32 because a bare `whoami` under a bash-flavoured PATH picks up the MSYS build, which rejects /user). Fallback when the SID can't be resolved is the domain-qualified `USERDOMAIN\username` name, which is unambiguous where the bare username was not. Windows-only regression tests assert the hardened directory stays usable by the calling process (readdir + write), which is exactly the check that a not-toThrow assertion sailed past before. Contributed by @asizux2 (PR #2479); the same defect was independently fixed by @Icandi40, @chiragborse1, @IntegriGit and @voltapix26. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(windows): forward windowsHide through the bun-polyfill spawn shims windowsHide is the one spawn option where Node's default is the opposite of Bun's: Node shows the child's console window, Bun.spawn hides it. The polyfill's spawn and spawnSync shims dropped the option entirely, so the Node fallback path (dist/bun-polyfill.cjs) silently inverted the behavior on the one platform the shim exists to serve — every watchdog respawn of the terminal agent popped a visible bun.exe console window. Three sites fixed: - Bun.spawnSync shim: forwards windowsHide with Bun-matching default true - Bun.spawn shim: same (stdio:'ignore' silences output but does NOT suppress the console window on Windows) - spawnTerminalAgent in terminal-agent-control.ts: explicit windowsHide: true, so the Node fallback path behaves like Bun-native An explicit windowsHide: false is honored at both shims. Three focused tests pin the default-true, default-true-sync, and explicit-false paths by intercepting child_process in a subprocess; the test file's require path now uses forward slashes so it survives interpolation into a JS string literal on Windows. Supersedes PRs #2523, #2294 and #2290, which each covered a subset of these sites.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(watchdog): signal-0 liveness, tick-scaled respawn guard, windowsHide Three-bug chain behind the Windows terminal-agent leak (console window strobing every 60s, one orphaned agent per watchdog tick until the box ran out of committable memory): 1. isProcessAlive shelled out to `tasklist /FI "PID eq <pid>"` on Windows with a 3s timeout. A Bun.spawnSync that hits its timeout still RETURNS with partial stdout, so the `.includes()` PID match read a LIVE agent as dead — killAgentByRecord skipped the kill, the watchdog respawned around the survivor, and every orphan slowed the next tasklist enough to produce the next false negative. Now: `process.kill(pid, 0)` on every platform (Node and Bun both map signal 0 to an OpenProcess existence check on Windows), with EPERM counted as alive. No subprocess, no timeout, no console window. 2. The respawn circuit-breaker was mathematically unreachable — verified in this tree: RESPAWN_GUARD_WINDOW_MS was a fixed 60_000 against a 60_000ms default tick, and each tick pushes at most one respawn timestamp, so three pushes span ~120s and can never coexist inside a 60s window (eviction is strict `>`, and setInterval drift plus per-tick work always ages the prior entry past the boundary). The guard could not fire at the default tick rate and a steady one-per-tick leak ran unbounded. The window now scales with the tick: max(60_000, tick * (RESPAWN_GUARD_MAX + 2)), so "3 crashes in quick succession → stop" holds at any tick value. 3. The tasklist probe popped a visible console per tick (no windowsHide). Removing the shell-out kills that site; the agent-spawn site itself already passes windowsHide: true (landed with the bun-polyfill windowsHide commit — PR #2414's terminal-agent-control.ts hunk is reconciled there rather than duplicated). New browse/test/process-liveness-windows.test.ts pins all three: no subprocess from the probe, a static tripwire against reintroducing `tasklist` + `PID eq` liveness checks in src/, the spawnTerminalAgent windowsHide + stdio contract, and the window-derived-from-tick arithmetic. terminal-agent-watchdog.test.ts test 4 now pins the window/tick relationship instead of the fixed literal that let this ship. Also converts `new URL(import.meta.url).pathname` to `import.meta.path` across the static-grep tests it touches — the pathname form yields /C:/... on Windows and breaks path.resolve.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(terminal-agent): tie agent lifetime to its owning browse server PID The terminal agent is intentionally detached so it survives the short-lived CLI launcher, but its real owner is the persistent browse server. If that server crashed or was killed before running normal shutdown, the agent was adopted by PID 1 and lived forever (#2019). spawnTerminalAgent now requires an ownerPid and exports it to the agent as BROWSE_OWNER_PID; all three spawn sites pass the server PID (cli.ts cold-start, cli.ts supervisor respawn, server.ts watchdog). The agent polls the owner with signal 0 every 15s (GSTACK_TERMINAL_OWNER_WATCHDOG_MS to tune) on an unref'd timer and, when the owner disappears, exits through the SAME cleanup path as an intentional SIGTERM shutdown — now re-entrancy-guarded and also removing the terminal-internal-token file alongside the port file and agent record. Runtime test spawns a real agent tied to a throwaway owner process, kills the owner, and asserts the agent exits and its discovery files (terminal-agent-pid, terminal-port) are gone. Reconciled with the watchdog commit's spawnTerminalAgent contract test (process-liveness-windows.test.ts now passes ownerPid and pins the BROWSE_OWNER_PID env forwarding). Closes #2019.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(windows): give the bun-polyfill spawn shim a real `exited` promise Bun.spawn exposes `proc.exited` as a Promise resolving to the exit code. The Node fallback shim (dist/bun-polyfill.cjs) returned no such field, so every `await proc.exited` on the Windows path resolved instantly to undefined — the Windows cookie picker (cookie-import-browser.ts races proc.exited at three sites) read stdout before the child produced it and silent-failed; browser-skill-commands and terminal-agent hit the same class. The shim now: - drains stdout/stderr eagerly into capped in-memory buffers (Node's Readables are pull-based; without draining, a child writing past the OS pipe buffer blocks in write() and 'exit' never fires), replaying them as fresh single-shot Web ReadableStreams so reads work before or after awaiting exit; - caps the buffer at 16 MB (GSTACK_SPAWN_MAX_BUFFER to override), still draining past the cap so a runaway child can't wedge or OOM; - resolves `exited` with Bun-matching codes (exit code, 128+signal, 1 on spawn error) after both pipes finish, and resolves on 'error' too — Node fires 'error' without 'exit' when the binary is missing, which otherwise hangs the await forever. Six tests pin exit codes, the read-after-exit ordering, spawn-failure resolution, the buffer cap, and the large-output drain. Adapted to the current test file (require path goes through the requirePath variable from the windowsHide commit), and the 1 MB drain test's child now exits in the write callback — on modern Node a pipe write past the OS buffer is async and process.exit() straight after write() truncates at ~64 KB even with a live reader, which fails the test for reasons unrelated to the shim.

Closes #2291. Applied the PR's override after the IS_WINDOWS detection, and also to the second BROWSE_BIN assignment the PR predates: the direct-Codex- install migration path re-derives BROWSE_BIN from the migrated dir and would otherwise drop the suffix again on Windows.

All five host-install sites now carry lib/ next to bin/, each through the existing _link_or_copy helper (never raw ln — the static invariant in test/setup-windows-fallback.test.ts enforces this): - .agents sidecar (create_agents_sidecar asset loop) - Codex runtime root (create_codex_runtime_root) - Factory runtime root (create_factory_runtime_root) - OpenCode runtime root (create_opencode_runtime_root) - Kiro install block New test/setup-runtime-lib-command.test.ts executes the real setup shell for each root in a sandbox (both the symlink branch and the Windows copy branch of _link_or_copy) and runs gstack-learnings-log end-to-end from the installed root, asserting the learning lands in ~/.gstack/projects/<slug>/learnings.jsonl — plus a negative control proving a bin-without-lib root fails exactly the way the bug report did. gen-skill-docs.test.ts's setup-validation block pins the lib link at every site.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * ci(windows): curate the fix-wave regression tests into the windows-latest run The windows-free-tests curated set is derived (POSIX-fragility regex scan + explicit deny list), and two of this wave's Windows regression files were auto-excluded on false-positive pattern hits: - browse/test/file-permissions.test.ts tripped the POSIX-mode-bitmask pattern, but every `mode & 0o777` assertion is platform-guarded — and the file carries the win32-only icacls-by-SID regression tests, which can only ever execute on windows-latest. - browse/test/terminal-agent-owner-watchdog.test.ts tripped the spawn(['bun','run',...]) pattern whose reason is the Playwright-bound browse server; it actually spawns terminal-agent.ts (fs/path/crypto + local helpers only, no Playwright at module scope), and the owner-PID orphan leak it pins was reported on Windows (#2019). Adds a KNOWN_WINDOWS_SAFE force-include list (mirror of KNOWN_WINDOWS_INCOMPATIBLE, each entry carrying its false-positive rationale) consulted before the pattern scan, and makes the owner-watchdog test's throwaway owner process Windows-portable (process.execPath instead of `sleep`, which a bare runner may not have). The wave's other new files need no wiring: process-liveness-windows and the bun-polyfill windowsHide/exited tests pass curation automatically; setup-runtime-lib-command self-skips on win32 by design (its Windows branch is exercised by simulating IS_WINDOWS=1 under bash), so force-including it would add a permanently-skipped file.

Fixes #2091, #2370. Union of both community fixes, compared at the diff level: - PR #2372: all 11 source sites with a suffix after the X-run — codex SKILL.md.tmpl (5), claude SKILL.md.tmpl (3), bin/gstack-developer-profile (2, suffix folded into the prefix: .json.tmp.XXXXXX), and the office-hours codex pass in scripts/resolvers/review.ts (1). - PR #2103: the second half of #2091 — bin/gstack-paths now strips the trailing slash from TMP_ROOT at the source (macOS $TMPDIR ends in `/`), plus runtime tests pinning that normalization. New repo-wide tripwire in test/regression-issue2091-bsd-mktemp.test.ts: every .tmpl, every SKILL.md, and every scripts/resolvers/*.ts is swept — no mktemp template may carry a suffix after the X-run, with a self-test so the detector can't be quietly blinded.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(codex,review,ship): scope codex review with an explicit --base flag, never prompt text `codex review` takes its scope ONLY from --base/--commit/--uncommitted. The positional [PROMPT] is mutually exclusive with all three, and a prompt-only `codex review "<text>"` silently falls back to the uncommitted working-tree scope (verified on 0.144.1: it runs `git status --short; git diff` and reviews that) — so the previous prompt-based scoping produced a confidently-worded review of the WRONG changes and read "no changes" on a clean tree. Every diff pass now invokes `codex review --base <base>` with no prompt argument: /codex Step 2A default path, the /review structured pass, and the /ship adversarial-section pass (all via scripts/resolvers/review.ts). Custom review instructions keep their own `codex exec` path (the CLI rejects prompt + scope flag together), with the filesystem boundary preserved there. Two new Error Handling entries teach the failure shapes: the argv-parse error, and the "review says no changes on a branch full of changes" symptom. Tests updated to pin the new invariant instead of banning the fix: the old assertions required the diff range in prompt text and banned the `--base <base> -c '...'` substring, which the correct scoped form contains. Also deletes test/fixtures/golden-ship-claude.md — a 2,565-line orphaned fixture referenced by zero tests (the live goldens are in test/fixtures/golden/, compared by test/host-config.test.ts); the factory golden is refreshed from the regenerated output.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(review,ship): run the codex diff passes under the timeout wrapper (#1036) The `_gstack_codex_timeout_wrapper` added in #1056 was wired into codex/SKILL.md but never into the /review and /ship diff passes, which kept running under a bare 5-minute Bash gate. An unwrapped stall returns no exit code and no output, which downstream reads as "Codex reviewed and found nothing" — a truncated pass silently became a clean bill. Measured on codex-cli 0.145.0: a pass was killed at 287s of a 300s budget mid-tool-call, and the same prompt completed in 336s. Both passes in scripts/resolvers/review.ts (adversarial `codex exec` and the structured `codex review --base` pass) now re-source gstack-codex-probe and run under `_gstack_codex_timeout_wrapper 540`, with the Bash tool gate raised to 600000 ms so the wrapper fires FIRST and a stall surfaces as a diagnosable exit 124. The timeout guidance now says a timed-out pass is MISSING COVERAGE, not a clean result, and points at the run's rollout log under ~/.codex/sessions/ for partial output. The stale "timeout doesn't exist on macOS" claim is gone — the wrapper resolves gtimeout, then timeout, then runs unwrapped, so it is safe without coreutils. Static guards in test/codex-hardening.test.ts pin all three sites (resolver, review/SKILL.md, ship/sections/adversarial.md): both calls wrapped, wrapper budget strictly under the Bash gate, and no reappearance of the macOS claim that steered these call sites away from the wrapper in the first place. The Claude-output path guard in test/gen-skill-docs.test.ts now scrubs ~/.codex/sessions/ (a user-facing Codex CLI path, same class as the ~/.codex/logs/ exemption) before banning Codex host paths.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(codex): sandbox the review path, fail the gate closed, order timeouts wrapper-first Closes #2496, #2524, #2477 — three defects in the class "a guard that reports success while doing nothing", all in codex/SKILL.md.tmpl: (a) Review sandbox. The default `codex review` path was the only codex call with no sandbox override, inheriting ~/.codex/config.toml's default — write access on a trusted project — while Important Rules claimed read-only. Top-level `codex review` has no -s/--sandbox flag (verified on 0.147.0), so the invocation now pins `-c 'sandbox_mode="read-only"'`, the same form the consult-resume path already uses. (b) Fail-closed verdict gate. The old rule ("no [P1] found → PASS") could not fail on the default path: native `codex review` output carries no bracketed tags, and a non-zero exit, expired auth, timeout, or empty result also contains no [P1] — all read as PASS. The gate is now an ordered, fail-closed check: non-zero exit → FAIL; empty output → FAIL; [P0]/[P1] (bracketed or codex's native labels) → FAIL with count; NO severity tags at all → FAIL requiring a human read; PASS is only reachable through the explicit tagged-advisory-only branch. [P0] is recognized as blocking, and the review-log findings count includes it. (c) Bash gate above the wrapper. Step 2A instructed `timeout: 300000` under a 330s wrapper, and Challenge's 300s gate sat under a 600s wrapper — the harness killed the call before the wrapper could emit its diagnosable exit-124 message. Every Bash gate now sits strictly ABOVE its wrapper: 360000 over the 330s review wrapper, 660000 over the 600s challenge/consult wrappers, with the ordering rationale stated at each site. Also from #2477/#2524: a new Error Handling entry for the model-entitlement 400 ("The '<model>' model is not supported...") pointing at the `model =` pin and `[notice.model_migrations]` in ~/.codex/config.toml and saying exactly which override to retry with (-m for exec-based modes, `-c model="..."` for review mode, which rejects -m); the Model & Reasoning section no longer documents `-m` for `/codex review`. Static assertions in test/codex-hardening.test.ts pin (a)-(c) across both the .tmpl and the generated SKILL.md: every scoped review invocation carries sandbox_mode="read-only" and never -s; the default-PASS sentence is banned and the fail-closed branches are present; and per-section, every Bash `timeout: N` is strictly greater than every wrapper budget, with 2A/2B/2C all required to be inspected.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(browse): dispatch a change event after fill for change-only validators Playwright's Locator.fill() dispatches `input` but never `change`, so frameworks that validate on change (AngularJS ng-change, debounced strength/match checks) never saw the filled value — correct in the DOM, failing the framework's own validation. `browse fill` now dispatches `change` after the fill. Failing-first regression test with a change-only password-match fixture included. Contributed by @intelliot (PR #2475). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(safety): unknown question-preference source exits the documented 2, not 1 The --write user-origin gate documents exit 2 as "rejected, do not retry" (profile poisoning defense), but a source outside both the allowed and the explicitly-rejected lists fell through to exit 1 — the generic validation code callers treat as retryable. Unknown sources now exit 2 with the same do-not-retry rejection message as the known non-user-originated ones. Closes #2390. Contributed by @gregario (PR #2429). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(pr-title): stop duplicating the version prefix on bare-version titles A title that was nothing but a version ("v1.2.3" — the form ship uses for version-only bumps) matched neither the "v<NEW_VERSION> " literal case nor the trailing-space strip regex, fell through to the prepend path, and came out as "v1.2.3.4 v1.2.3" — which pr-title-sync.yml then wrote back via gh pr edit. Handle the bare form in both the no-change case and the prefix-strip regex, and emit a bare new version when nothing follows. Closes #1886. Contributed by @jbetala7 (PR #1887). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(build): escape literal braces in the bun:sqlite stub regex Perl >= 5.26 treats an unescaped literal `{` in a pattern as fatal ("Unescaped left brace in regex is illegal"), so build-node-server.sh died at the bun:sqlite stub substitution on modern perl. Escape both braces; the replacement output is unchanged. Closes #2300. Contributed by @nuga0718 (PR #2111). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(config): preserve spaces in gstack-config values get/list read values with awk '{print $2}' | tr -d '[:space:]', which truncated any value containing spaces ("/Users/x/Conductor Workspaces" came back as "/Users/x/Conductor") and set wrote the unfiltered raw value on the append path. New read_config_value() strips only the "key:" prefix and trailing whitespace (cut-style parse), and set appends the same newline-stripped value the in-place edit path uses. Closes #1782. Contributed by @jbetala7 (PR #1783). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(browse): recover a late-healthy detached daemon instead of a false "Server failed to start" startServer spawns the daemon detached + unref'd, then polls health for a fixed budget. On a loaded machine the budget can elapse in the gap between the loop's last tick and the daemon becoming ready — the CLI reported "Server failed to start within Ns" while the very next `browse status` showed a healthy server. Add a final readState()+isServerHealthy() re-check before the timeout throw, and make the budget env-overridable via BROWSE_START_TIMEOUT (BROWSE_* tunable convention). Structural + behavioral tests pin both invariants. Closes #1846. Contributed by @harjothkhara (PR #1847). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(browse): daemon resilience on loaded machines — Bun conn errors, stop/restart flush, startup + git-root budgets Four load-sensitivity fixes in the daemon lifecycle: - sendCommand only recognized Node's ECONNREFUSED/ECONNRESET; the compiled CLI runs on Bun, which reports 'ConnectionRefused'/'ConnectionClosed' ("Unable to connect..."), so daemon crashes leaked the raw error and exited 1 instead of entering the busy-check/restart path. Match both. - stop/restart called shutdown() inline, which exits before the HTTP response flushes — the CLI saw a dropped socket (and would now crash-retry a fresh daemon just to stop it). Defer shutdown ~100ms so the 200 lands first. - Non-CI POSIX startup budget raised 8s -> 15s (cold Chromium measured ~5.7s at load avg 10; load 12+ blew the old budget while the detached daemon was still booting). - getGitRoot's 2s git rev-parse timeout returned null under load (6.3s spikes measured), scattering state files across cwds into split-brain daemons. Raise to 8s, still bounded. Contributed by @mplatts (PR #1732). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(telemetry): ingest keeps error_message/failed_step instead of dropping them The telemetry_events columns exist and bin/gstack-telemetry-log already sends error_message + failed_step, but the Supabase ingest function dropped both fields on insert — every error report arrived with no message and no failing step. Map them through with the same bounded-length sanitization as error_class (500/100 chars). The completion-status resolver now also passes --error-message/--failed-step in the generated skill telemetry block, with instructions to leave them empty on success. Resolver only for the template side; generated SKILL.md files regenerate from this source in the docs lane. Contributed by @sunnnybala (PR #769). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(browse): surface non-EEXIST errors in acquireServerLock instead of masking them acquireServerLock caught every open failure as if the lock were held: EACCES/EROFS/ENOENT surfaced as phantom "another process holds the lock" (null return, no diagnostics), and a failed stale-lock read or unlink was swallowed the same way. Each failure class now logs a coded, pathed diagnostic: non-EEXIST open errors, holder-PID read errors (ENOENT retries the acquire — the holder released between open and read), and stale-lock unlink errors. Four-case unit test included. Closes #1084. Contributed by @jbetala7 (PR #1725); same fix independently by @JiayuuWang (PR #1097). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(paths): shell-quote gstack-paths output so eval round-trips values gstack-paths emitted bare KEY=VALUE lines, so the documented eval "$(gstack-paths)" re-parsed the values: backslashes were eaten as escapes (Windows $TMP C:\Users\... became C:Users...) and a space word-split the assignment, leaving the variable empty. Emit each value with printf %q so eval round-trips byte-for-byte; plain POSIX paths are unchanged. Round-trip regression tests cover backslashes, spaces, and embedded quotes. Closes #2374.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(benchmark): validate --timeout-ms as a positive integer gstack-model-benchmark fed --timeout-ms straight through parseInt, so "abc" became NaN and "0"/"-1" passed through — a NaN or non-positive timeout silently disables the per-provider watchdog.

Lead with PingFang SC / Heiti SC / Noto Sans CJK SC / Source Han Sans SC before the JP fallbacks. - Quote-smartening only recognized ASCII openers as "start of quote" context; the fullwidth colon and CJK brackets now count, so quotes after them curl the right way.

Cached identity now wins, with one precise exception: when the cached value equals THIS pwd's basename while the walk-up proves pwd is not the project root, the entry came from the pre-walk-up subdirectory bug (#1125) and is recomputed.

Garry Tan	11de390be1	v1.58.5.0 feat: first-run activation scaffold + gstack router front door (#2078) ... * feat: first-run activation — project-aware scaffold, router front door, onboarding nudges Adds the activation system that drives a new install toward a concrete first move: - bin/gstack-first-task-detect: local-git+filesystem repo classifier emitting one validated enum bucket (greenfield/code_<lang>/branch_ahead/dirty_default/clean_default), portable timeouts, fail-safe empty output. - generate-first-run-guidance.ts: unified preamble section — first-run project-aware scaffold + returning-session plan->review->ship tip, gated on a persistent .activated marker and never run in headless. Detection wired lazily in generate-preamble-bash.ts. - SKILL.md.tmpl: top-level gstack skill is now a pure router (browse body removed; it lives in /browse), routing any request and sending browser/QA work to /browse. - setup: first-move nudge on first install. office-hours: closing handoff that launches the next review via the Skill tool. - telemetry-ingest: accept onboarding/first_task_scaffold_shown/handoff/route event types. * test: cover first-run detection + repoint browse-content assertions to /browse - New unit tests for every detection bucket, the eval-safe enum contract, and the first-run gating (test/preamble-first-task-scaffold.test.ts); periodic E2E that runs the detector through the real harness (test/skill-e2e-first-task-scaffold.test.ts). - Repoint browse-content assertions (gen-skill-docs, audit-compliance, skill-validation, LLM-judge eval) from the root skill to browse/SKILL.md following the router split; add a regression pinning that the router carries no browse body. - Register first-task-scaffold touchfiles + periodic tier; bump parity/carve size caps ~1-2KB per skill for the shared first-run-guidance preamble section. - Refresh ship golden fixtures for the preamble addition. * chore: regenerate SKILL.md + llms.txt for first-run activation * chore: bump version and changelog (v1.58.5.0) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(test): repoint bws skillmd-* setup-block assertions to browse/SKILL.md The skillmd-setup-discovery / -no-local-binary / -outside-git E2E tests extracted the `## SETUP`→`## IMPORTANT` browse binary-discovery block from the root SKILL.md. P2 moved that block to browse/SKILL.md (end anchor is now `## Core QA Patterns`), so the slice came back empty and the `browse/dist/browse` guard failed. Repoint to browse/SKILL.md. Verified: 7/7 e2e-browse pass locally. * fix(test): tolerate skill-discovery race in PTY plan-mode smoke The e2e-pty-plan-smoke suite (office-hours / plan-mode-no-op) failed in CI with `Unknown command: /office-hours` (claude exited ~10s) while passing locally. Root cause: a cold CI container's overlay-FS scan of the symlinked ~/.claude/skills registry finishes AFTER the runner's 8s boot grace, so the first `/skill` send reaches claude before the skill is indexed and is rejected as unknown. The runner gave up on the first "Unknown command:" line. runPlanSkillObservation now re-sends the skill command up to 3x (6s apart), re-marking the buffer each time so stale scrollback can't re-trip the check, before concluding the skill is genuinely unregistered. A real dangling-symlink / missing-skill still surfaces as 'exited' (after retries), preserving the original diagnostic. Pure-helper contract unchanged: 95/95 unit tests pass. This is a pre-existing harness bug (fails identically on #2077's own branch, which introduced the suite) surfaced while shipping the activation feature. * debug(ci): temporarily instrument pty-smoke skill discovery Capture claude version, env, registry tree, and a claude -p discovery probe to pin why /office-hours isn't discovered in CI (retries proved it's not a race). Temporary — revert once the registry fix is identified. * chore: revert pty-smoke harness experiments (race-retry + CI debug step) Diagnosis is conclusive and the experiments aren't the fix, so restore the harness to its original state (net-zero diff vs main for both files). What the CI debug step proved: `claude -p` returns READY — claude v2.1.187 fully DISCOVERS /office-hours from the symlinked registry. Only the interactive PTY TUI rejects it as "Unknown command" (and it received the full command text). So the e2e-pty-plan-smoke failure is a claude 2.1.187 interactive-TUI regression (skills discovered by `claude -p` aren't exposed as TUI slash commands), pre-existing in the #2077 harness and failing identically on its own origin branch — unrelated to this activation PR. The race-retry can't help (the TUI genuinely lacks the command); the debug step also tripped actionlint (shellcheck SC2012). Both reverted. * fix(ci): copy SKILL.md as real files in pty-smoke registry (cross-mount symlink) The e2e-pty-plan-smoke suite failed with "Unknown command: /office-hours" in CI while passing locally. Root cause (proven, not guessed): claude 2.1.187's interactive-TUI skill scanner does not follow the /github/home -> /__w cross-mount symlink the registry used for per-skill SKILL.md. Evidence: a CI debug step showed `claude -p` discovered the skill (printed READY), and a local macOS repro with the identical symlinked registry recognized /office-hours — isolating the failure to the container's cross-mount symlink, not registration content, claude version, duplicate names, or a race. Fix: register the per-skill SKILL.md + sections as REAL copies (same mount as $HOME) so the TUI reads them directly. The gstack root stays a symlink — the preamble's runtime bash resolves bin/* and sections/* through it and bash follows cross-mount symlinks fine. * fix(ci): guard rm expansion in pty-smoke registry (shellcheck SC2115) * fix(ci): also register pty-smoke skills project-scoped (cwd/.claude/skills) The real-file user-dir registration still left the TUI rejecting /office-hours in the container. claude's interactive TUI surfaces /slash commands from the PROJECT dir (<cwd>/.claude/skills); the smokes run with cwd=$REPO whose .claude/skills is gitignored (absent on a fresh CI checkout), so the user-dir registry feeds `claude -p` (READY) but not the TUI. Populate $REPO/.claude/skills with real SKILL.md + sections copies (no gstack symlink there — it would point at its own parent; runtime paths use the user-dir gstack symlink). --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-25 09:42:45 -07:00
Garry Tan	9fd03fae9e	v1.58.4.0 fix: high-priority community bug wave + PTY plan-mode smoke gate (#2077) ... * fix(gbrain): stop forcing GBRAIN_PREPARE on transaction-mode poolers (#1965) buildGbrainEnv auto-set GBRAIN_PREPARE=true whenever DATABASE_URL targeted port 6543, and the /sync-gbrain capability check exported it for the rest of the skill run. Both had the semantics inverted: gbrain auto-disables prepared statements on transaction-mode poolers because they break every write there ("prepared statement does not exist"); GBRAIN_PREPARE=true is gbrain's documented override for SESSION-mode poolers on 6543, not a requirement for transaction mode. The #1435 search symptom the auto-set worked around was fixed gbrain-side. Remove both force-sets. A caller-set GBRAIN_PREPARE (either value) still passes through untouched, preserving the session-mode-on-6543 escape hatch. isTransactionModePooler stays exported. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(gbrain): classify probe timeout as its own status; sync proceeds instead of skipping (#1964) The 5s engine probe misclassified healthy-but-slow engines (cold Supabase pooler connections measured at 6.9-10.7s) as broken-config, so /sync-gbrain silently skipped code+memory and told the user their config was malformed. - New "timeout" status: probe killed at the deadline with no recognized stderr pattern. Default deadline is now 15s, overridable via GSTACK_GBRAIN_PROBE_TIMEOUT_MS (tests set 300ms against a fake that sleeps 2s). - Sync stages PROCEED on timeout with a stderr warning naming the env knob; a genuinely-dead engine surfaces its real error at the first operation instead of a false config diagnosis. - Consistency everywhere "ok" gated behavior: gstack-gbrain-detect --is-ok exits 0 on timeout, and gen-skill-docs' detection gate accepts it, so a slow engine no longer silently suppresses brain-aware features. - Status cache: key now includes the effective probe timeout (raising it invalidates a cached timeout) and GBRAIN_HOME; config detection honors GBRAIN_HOME so relocated-home users stop being misclassified as missing-config. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(bins): cygpath-normalize SCRIPT_DIR for bun imports; surface learnings-log errors (#1950) Under Windows git-bash, pwd yields a POSIX path (/c/Users/...) that Bun on Windows cannot resolve as an ES module specifier. gstack-learnings-log interpolates SCRIPT_DIR into a bun -e import, so every invocation died with "Cannot find module" — and 2>/dev/null swallowed the error, silently dropping every AI-logged learning for Windows users. - 3-line cygpath -m guard in gstack-learnings-log and gstack-question-log (which gains the same import shape in the next commit). Matches the duplicated IS_WINDOWS convention in setup; no shared shell lib exists. - learnings-log adopts question-log's set +e / TMPERR capture pattern wholesale: validation errors now print to stderr. The old `if [ $? -ne 0 ]` check was dead code under set -euo pipefail — the script exited at the failing assignment before reaching it. - New test/bin-windows-bun-import-paths.test.ts: static invariant (any bash bin interpolating $SCRIPT_DIR into a bun -e import must carry the guard) + behavioral end-to-end run invoked via `bash <bin>` — added to the windows-free-tests workflow list so the conversion is proven on the only platform where the bug exists. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(question-log): dedupe INJECTION_PATTERNS via lib/jsonl-store (#1934) bin/gstack-question-log carried a local copy of the injection-pattern list, so pattern fixes to lib/jsonl-store.ts never propagated — including the /override[:\s]/i false-positive fix arriving via community PR #1940. Import the shared hasInjection instead (enabled by the previous commit's cygpath guard). question-log also gets the lib's stricter superset (human:, disregard, from-now-on, approve-all patterns). Tests pin the contract in a #1940-order-independent way: an "Override: ignore all previous instructions" header is rejected, "prose overrides the deterministic table" is accepted, and a static invariant keeps local INJECTION_PATTERNS duplicates out of the bin. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(security): community-pulse + both dashboards never report fake zeros (#1947) The security-signaling surface failed open at three layers — every failure mode read as a reassuring "0 attacks" / "0 installs": - community-pulse edge function: supabase-js returns {data,error} without throwing, and all five queries discarded `error` — a DB outage produced real-looking zeros via the SUCCESS path, and the catch (also returning zeros with HTTP 200) was unreachable for query failures. Every query now destructures and throws; the catch serves the stale cache (marked "stale": true) when one exists, else 503 {"error":"pulse_unavailable"}. Success responses carry "status":"ok" so clients can distinguish authoritative data from legacy backends. NOTE: the edge function deploys out-of-band (supabase functions deploy community-pulse). - gstack-security-dashboard: captures the HTTP status; non-200 / network failure / error body / missing section → "unknown — backend error"; jq missing → "unknown — install jq" (the lossy grep fallback broke on nested arrays and under-reported attacks as zero — removed); a 200 without the new marker shows figures with an "unverified (legacy backend)" note. Also fixes a latent display bug: the TOTAL grep matched the digit 7 inside "attacks_last_7_days" and misreported every count. - gstack-community-dashboard: same class — curl || echo "{}" plus grep || echo "0" printed "Weekly active installs: 0" on any failure. Now "unknown — backend error (HTTP N)". test/security-dashboard-fallback.test.ts pins the matrix (200+marker, 200-legacy, 503, network failure) x (jq present, jq absent) for both bins: "unknown" states never render as 0. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(telemetry): redact error_message spans before they leave the machine (#1947) error_message was uploaded with only quote/newline escaping — stack traces and failed-API errors can embed credentials, private paths, and hostnames, and the sync path strips only _repo_slug/_branch. New lib/redact-engine.ts export redactFindingSpans(): replaces EVERY finding's span with <REDACTED-{id}> regardless of tier (applyRedactions is the interactive PII-only path and exits nonzero on credential findings, so it can't serve machine egress). Returns null when a span can't be located — callers drop the whole payload rather than risk a leak. gstack-telemetry-log pipes error_message through it at LOG time, so the local JSONL at rest is clean too; surrounding text survives for crash triage. FAIL CLOSED: bun missing, engine error, or non-JSON-string output all null the field. Tests pin: embedded ghp_ token → <REDACTED-github.pat> with context intact; redactor unavailable → null; raw bytes on disk never contain the token. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(redact): prepush guard fails closed on git failure; /ship owns hook install (#1946) Two gaps closed: 1. Fail closed. The git() helper returned "" on ANY non-zero exit or maxBuffer overflow (status null), addedLinesFor produced an empty string, and the push sailed through unscanned — fail-open on exactly the oversized-diff case where a large secret-bearing blob is most likely. The diff call now uses a strict variant that throws; main blocks with a clear message naming the GSTACK_REDACT_PREPUSH=skip escape valve. Probe calls (symbolic-ref, rev-parse, merge-base) keep the permissive helper — their failures are normal control flow. 2. Install path. The hook was installed by nothing ("opt-in, installed by nothing" was the issue's words). ./setup runs in the gstack checkout — the wrong repo for a per-project hook — so it gets a one-line hint only. /ship owns per-repo install: config redact_prepush_hook=true + hook missing → silent install (consent already given); config unset + no ~/.gstack/.redact-prepush-prompted marker → one-time machine-wide AskUserQuestion offer, answer persisted. ship/SKILL.md regenerated in this same commit (check-freshness bisect discipline). Tests: unscannable diff (bogus SHAs) → exit 1 + valve named; empty-but- successful diff → exit 0; static asserts pin setup as hint-only and the ship template as the installer surface. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(redact): six new credential patterns — GitLab, HuggingFace, npm, DigitalOcean, Bearer, GCP SA (#1946) Coverage gaps from the #1946 security review, including token types for tooling gstack itself drives (glab): HIGH (block): gitlab.token (glpat-/glptt-/gldt-), huggingface.token (hf_), npm.token (npm_), digitalocean.token (dop_v1_), gcp.service_account (the JSON-escaped "private_key" form that dodges pem.private_key's literal-block match when minified, confirmed by "private_key_id" proximity). MEDIUM (warn): auth.bearer — the most FP-prone shape in the set (docs are full of "Authorization: Bearer <token>"), so it requires header-context proximity and the same entropy>=3.0 + placeholder validator recipe as env.kv. "Bearer YOUR_TOKEN_HERE" never fires; calibration over coverage, per the cries-wolf principle. All shapes are linear-time; test/redact-pattern-lint.test.ts covers them automatically. Engine tests add positive + placeholder-negative cases per pattern. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test: coverage-audit additions for the fix wave Ship Step 7 gap-fill (all passing, 248 tests across the touched suites): memory + dream stage probe-timeout proceeds, gbrain-detect override paths, stale-flag passthrough, 200-body-missing-.security fail-closed case, telemetry redaction edges, and credential-pattern edge cases. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix: pre-landing review fixes Review army findings (1 critical, auto-fixed with regression tests): - CRITICAL (security specialist, verified live): redactFindingSpans spliced only the regex capture span, and pem.private_key / gcp.service_account capture just the BEGIN-header — the key body survived "redaction" and shipped via telemetry. Marker-only patterns now drop the whole payload (null, fail closed). Overlapping spans (Bearer+JWT on the same bytes) are coalesced before splicing so stale offsets can't leave partial secret bytes behind. - gitStrict: drop the dead `|| r.status === null` disjunct (null !== 0 already covers it); add the signal-kill/null-status regression test the docstring promised. - security-dashboard human mode flags stale snapshots ("figures may be out of date") instead of presenting frozen counts as current. - community-dashboard marker check uses jq when available — the grep-only variant misclassified whitespaced/reserialized bodies as legacy. - telemetry fail-closed test now shadows bun with a failing stub (deterministic on any host layout); stale "five status cases" describe title renamed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix: adversarial review fixes (Claude + Codex cross-model passes) Both adversarial passes ran against the wave; every FIXABLE finding landed with a regression test: - probeTimeoutMs clamps to >=1ms: a fractional override floored to 0, and execFileSync treats timeout:0 as NO timeout — the probe that exists to bound hangs could hang forever (found by both models independently). - /ship silent hook install now requires the hooks dir to live inside .git: with core.hooksPath (husky's COMMITTED .husky/), the chaining installer would have renamed the team's committed pre-push and written a machine-local wrapper into the working tree (found by both models). - gstack-config gbrain-refresh accepts the "timeout" status — the last consumer still gating on literal "ok" (Codex); gstack-gbrain-detect's config-derived fields honor GBRAIN_HOME so the detection JSON can't report status ok alongside config_exists false (Codex). - prepush: a remote sha absent locally (shallow clone / stale fetch) falls back to the merge-base/empty-tree range — scans MORE, never blocks a legitimate push into training users toward --no-verify. - dashboards: curl's own 000 no longer doubles to "HTTP 000000"; the community dashboard flags stale snapshots like the security one; array sections parse via jq (the sed/grep loops truncated at the first ']'); the no-jq marker grep tolerates whitespace. - telemetry: multi-line redactor output nulls the field instead of corrupting the JSONL record; setup's hint fires only when the config key is genuinely unset (an explicit false is a recorded decline); the /ship prompt marker honors GSTACK_HOME. Kept as designed (cross-model tension noted): Bearer stays MEDIUM in the prepush gate — a HIGH Bearer would block every docs example; the entropy validator can't eliminate that FP class, and MEDIUM warns visibly. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * chore: bump version and changelog (v1.57.11.0) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * docs: P1 TODO — eval harness live progress + incremental persistence Root-caused during this ship: a killed eval run was indistinguishable from a healthy one for hours (per-file output buffering across mega test files, no incremental eval-store writes, no honest liveness signal). Full context and starting points in the entry. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test: fix operational-learning E2E fixture — copy lib/jsonl-store.ts Pre-existing breakage, proven on main: gstack-learnings-log has imported lib/jsonl-store.ts (shared injection patterns) since v1.57.5.0 / #1910, but the fixture copies only the bin scripts — the bin exits 1 before writing anything, on main silently (stderr swallowed) and on this branch loudly (the #1950 error-surfacing made the four-day-old failure visible). A real install always ships bin/ and lib/ together; the fixture now does too. Verified: the fixture-shaped invocation writes the learning (exit 0) with lib present, exits 1 on both main and this branch without it. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(ios-qa): isolate E2E tests under --concurrent (3 real races) The ios-qa E2E file failed intermittently under `bun test --concurrent` (the eval harness default). Three distinct shared-state races, all fixed: 1. Shared pidfile: a module-level `workDir` reassigned in beforeEach was clobbered by parallel tests, so concurrent daemons collided on the same pidfile and the loser returned `already_running`. Each test now gets its own dir via makeWorkDir(). 2. process.env path globals: tests set GSTACK_IOS_AUDIT_PATH / _ATTEMPTS_PATH / _ALLOWLIST_PATH on the shared process env; concurrent tests stomped each other's audit/attempts destinations. Threaded auditPath/attemptsPath/allowlistPath through DaemonOptions (and mintForCaller) as explicit args — env is no longer load-bearing. 3. afterEach cleanup race: the per-test cleanup drained a shared dir array, so the first test to finish deleted still-running tests' workDirs mid-assertion. Moved to afterAll (cleans once, after all settle). Verified: 5/5 clean full-suite runs at --max-concurrency 15 (was intermittent); daemon unit suite 91/91; daemon source compiles. The paths default to the env-derived locations when options are omitted, so the production CLI path is unchanged. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(pty): pin spawned claude to EVALS model chain (default claude-sonnet-4-6) launchClaudePty spawned the interactive `claude` TUI with no --model flag, so the child inherited the operator's ~/.claude/settings.json model. On a slow-thinking model that meant 5+ min of extended thinking on empty plan-mode context, timing out the plan-mode smoke tests regardless of contention. Pin the model via opts.model ?? EVALS_MODEL ?? 'claude-sonnet-4-6' — byte-identical to session-runner.ts:144, so PTY and `claude -p` evals always agree. Pushed before extraArgs (last flag wins, so a per-test --model still overrides). Placement leaves the spawn region byte-stable for a clean merge with the in-flight hermetic-env branch. Plumbed model through the three plan-skill wrappers. Static-grep tripwires guard the pin, its fallback chain, the before-extraArgs ordering, and all three wrapper forwards. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(pty): detect markdown bold-bullet prose AUQs (fixes office-hours smoke) office-hours auto-mode renders its mode question as `- **Building a startup**` markdown bullets (office-hours/SKILL.md.tmpl:102) with no letter/number marker. isProseAUQVisible only matched `A)`-style lettered or `1.`-style numbered options, so the question went undetected: the model surfaced it at ~2m19s (well under the 300s budget) but the harness kept scoring the run "working" off the spinner glyphs and timed out — a false timeout on a question that was already on screen. Add Pattern 3: when an interrogative line ('?') is present AND 3+ bold-bullet markers (`- **`) appear in the 4KB tail, classify as a prose AUQ. Bold is the discriminator vs incidental prose bullets; the line anchor is dropped (stripAnsi can collapse option lines) and the existing `❯ 1.` cursor gate still defers to a live native list. Wires through the existing classifyVisible 'asked' path and the timeout high-water-mark, so office-hours now classifies 'asked' instead of 'timeout'. Five unit cases: the office-hours render passes; no-'?', <3-bullet, plain-bullet, and native-cursor cases stay false. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(pty): detect stripAnsi-collapsed prose AUQs + judge spinner-precedence The plan-eng/plan-design plan-mode + finding-floor smokes timed out even when the skill HAD rendered a complete prose AskUserQuestion and was waiting: the PTY strips cursor-positioning escapes, collapsing the option newlines/spaces so "A) ..." arrives as "A(recommended)" / "-B:" and "Reply with A, B, or C" as "ReplywithA,B,orC". Every line-anchored detector (Patterns 1-3) returns false on those bytes, so proseAUQEverObserved never latched and the run timed out on a question that was already on screen. Add Pattern 4/5: a two-signal collapsed-form detector — a reply/recommendation marker (space-insensitive "reply with [A-D]", "Recommendation:", or "(recommended)") AND 2+ distinct A-D letters each punctuated by ) : or (. The conjunction is what separates a real AUQ from incidental report prose; verified true on the verbatim failing-run buffers where Patterns 1-3 return false. Also fix the Haiku judge spinner bias: of 614 verdicts, 569 were 'working' and 95 of those noted a question was visible — Claude Code keeps the spinner animating at an idle prose decision, so the judge coin-flipped. Add a precedence override: when an option list AND a Recommendation/Reply instruction are both visible, classify WAITING even with spinner glyphs. Kept the strict dual-signal gate (never option-list-alone) so auto-decide-preserved doesn't flip. 5 unit tests pin the two-signal contract (2 true on real collapsed bytes, 3 false guards). 90 -> 95 pass. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(plan-review): ask-first scope gate for plan-eng + plan-design review On an empty/cold invocation, plan-eng-review and plan-design-review would dive straight into repo exploration (plan-eng) or a 7-pass mockup+audit (plan-design) and only ask the user much later, if at all. plan-ceo-review already asks first via an unconditional Step-0 gate and behaves well; these two did not. Add a hard-STOP scope gate as the FIRST operational instruction in each skill (above the design-doc check / pre-review audit / mockup defaults it explicitly overrides): the first tool call must be AskUserQuestion confirming the review target, before any git/Read/Grep/Glob/Bash or mockup generation. Under --disallowedTools the options render as plain column-0 lettered prose with a Recommendation + "Reply with A, B, or C" line so the answer is detectable. This is correct cold-start UX (confirm what to review before grinding a full review on nothing) and it is the product half of the plan-mode smoke fix; the harness collapsed-form detector is the deterministic half that catches the ask however it renders. Templates + regenerated SKILL.md (default variant). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(tiers): reclassify stochastic plan-eng/plan-design ask-first smokes as periodic plan-eng-review and plan-design-review run a long explore/audit before their first AskUserQuestion, so whether the plan-mode + finding-floor smokes reach a terminal outcome within the 300s/600s budget depends on stochastic ask-first compliance (measured ~50-67%/run even with the hardened gate). Per the "non-deterministic -> periodic" tiering rule, move the four affected smokes (plan-eng/plan-design review-plan-mode + finding-floor) to periodic. The deterministic harness fix (collapsed-form detector + judge precedence) and the ask-first gate lift these from always-failing to mostly-passing and are the real product+harness improvements; periodic monitoring tracks the rate weekly without blocking PRs on an LLM coin-flip. plan-ceo/plan-devex ask-first reliably and stay gate-tier. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * ci(evals): gate the deterministic PTY plan-mode smokes in CI The real-PTY plan-mode smokes never ran in CI — the gate was local-only. Add an e2e-pty-plan-smoke matrix suite running the two deterministically-reliable ones (office-hours-auto-mode, plan-mode-no-op) so a regression there blocks PRs. The stochastic plan-eng/plan-design ask-first smokes stay periodic (touchfiles E2E_TIERS) and are not CI-gated. A fresh CI container has no ~/.claude.json, so the spawned interactive `claude` would wedge on the onboarding + API-key-approval dialog. Add a scoped seed step (hasCompletedOnboarding + key approval, its own ANTHROPIC_API_KEY env) before the run — mirrors what the hermetic E2E child env seeds. Per-suite timeout override (35 min) via matrix.suite.timeout so the PTY suite has headroom for --retry 2 without bumping the other 12 suites. Report runner count 12 -> 13. Validate via workflow_dispatch before relying on the gate (PTY-in-CI is new). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * ci(evals): install gstack skill registry for the PTY smoke suite The first dry-run of e2e-pty-plan-smoke failed: the spawned interactive `claude` printed "Unknown command: /plan-ceo-review". .claude/skills is gitignored, so a fresh CI checkout has no gstack skill registry and the TUI can't resolve /office-hours or /plan-ceo-review. Add a Register step (scoped to the suite, after Seed, before Run) that mirrors setup's --no-prefix user-scoped registry minimally: $HOME/.claude/skills/gstack -> repo (resolves the preambles' absolute ~/.claude/skills/gstack/bin/* and <skill>/sections/* paths) + per-skill SKILL.md/sections symlinks for the two skills these tests invoke. HOME is /github/home in this container and the runner adds no HOME/CLAUDE_CONFIG_DIR override (no hermetic mode), so $HOME is the right anchor — the Seed step already proved claude reads it. No ./setup (binary build + Chromium + fonts + /dev/tty prompt); SKILL.md + bin/ + sections/ are committed. Self-validating: fails the step loudly on a dangling symlink or missing `name:` frontmatter, so a moved target surfaces here instead of as a silent 35-min "Unknown command" timeout.

Garry Tan	40d00bd2ce	v1.41.1.0 fix wave: 7 HIGH bugs from external audit + regression tests (PR #1169 follow-up) (#1592) ... * fix(build-app): escape sed replacement metachars in Chromium rebrand build-app.sh injects \$APP_NAME directly into the replacement half of sed's s/// when patching Chromium's localized InfoPlist.strings. If \$APP_NAME ever carries '/', '&', or '\\' — the command either breaks or starts interpreting input as sed syntax. The trailing '|| true' would then silently hide the failure and ship a DMG that still says 'Google Chrome for Testing' in the menu bar. Escape replacement metachars before substitution. No change for the default name 'GStack Browser'. * fix(build-app): bail out if 'mktemp -d' fails instead of cp-ing into '/' The DMG creation step sets DMG_TMP from 'mktemp -d' with no error check. If mktemp fails (tmpfs full, permissions, TMPDIR misconfigured), DMG_TMP is empty and the very next line — 'cp -a "\$APP_DIR" "\$DMG_TMP/"' — expands to 'cp -a "<app>" "/"', which copies the bundle into the root of the filesystem. Refuse to continue unless mktemp produced a real directory. Defensive second check catches the (rare) case where mktemp succeeds but returns something that isn't a directory we can cp into. * fix(telemetry-sync): drop predictable $$ tmp-file fallback gstack-telemetry-sync tried 'mktemp /tmp/gstack-sync-XXXXXX' and on failure fell back to '/tmp/gstack-sync-$$'. $$ is the PID — predictable and reusable, so on shared hosts another user can pre-create or symlink the path and either steal the response body or clobber an unrelated file when curl writes through it. Drop the fallback. If mktemp cannot produce a unique file we just skip this sync cycle — the events stay on disk and the next run picks them up. Also install an EXIT trap so the response file is cleaned up on unexpected exit, not just on the happy path. * fix(verify-rls): drop predictable $$-based tmp file fallback Same shape as gstack-telemetry-sync: on mktemp failure the script fell back to '/tmp/verify-rls-$$-$TOTAL', which is fully predictable from the PID and a per-check counter. On a shared box another user can pre-create or symlink the path and either capture the HTTP response body (which may leak what the RLS tests revealed) or corrupt an unrelated file that curl writes through. Make mktemp strict. On failure return from the check function; the caller tallies a FAIL and the run moves on. * fix(security-classifier): close writer + delete tmp on download error downloadFile() opens an fs.WriteStream to '<dest>.tmp.<pid>' and drives it from a fetch body reader, but if reader.read() or writer.write() throws mid-download the writer is never closed. That leaks an FD per failed attempt and leaves the half-written tmp on disk. A later retry can land in renameSync(tmp, dest) with a truncated TestSavantAI / DeBERTa ONNX file — which then loads but produces garbage classifier verdicts until the user manually nukes the models cache. Wrap the download loop in try/catch. On failure, destroy() the writer and unlink the tmp before rethrowing, so the next attempt starts from a clean slate. * fix(meta-commands): guard JSON.parse in pdf --from-file parser parsePdfFromFile() runs JSON.parse on user-supplied file contents with no try/catch. A malformed payload surfaces as an uncaught SyntaxError from the 'pdf' command handler and the user sees an opaque stack trace instead of "this file isn't valid JSON". Worse, the same call path is used by make-pdf when header/footer HTML would overflow Windows' CreateProcess argv cap, so a corrupt payload file there can take down the make-pdf run. Wrap JSON.parse. Re-throw with a message that names the offending file and echoes the parser's own explanation. Also reject top-level non- objects (null, array, primitive) since the rest of the function treats json as an object — catching that here produces a clear error instead of a TypeError further down. * fix(global-discover): stop dropping sessions when header >8KB extractCwdFromJsonl() reads the first 8KB of each JSONL session file and runs JSON.parse on every newline-split line. When a session record happens to straddle the 8KB cap, the last line ends in a truncated JSON fragment, JSON.parse throws, the catch block 'continue's silently, and if that was the only line carrying 'cwd' the whole project gets dropped from the discovery output without a warning. Two independent hardening steps: 1. Raise the read cap to 64KB. Session headers observed in Claude Code / Codex / Gemini transcripts fit comfortably; this just moves the cliff out of the normal range. 2. Drop the final segment after splitting on '\\n'. If the read hit the cap mid-line, that segment is guaranteed incomplete; if the file ended inside the buffer, the split produces an empty final segment and dropping it is a no-op. Together these make the parser robust regardless of how verbose the leading records are. * test: export downloadFile, parsePdfFromFile, extractCwdFromJsonl These three internal helpers are now imported by regression tests landing in the next commits (PR #1169 follow-up). Pattern matches the existing normalizeRemoteUrl export in gstack-global-discover.ts which test/global-discover.test.ts already imports side-effect-free. No change to runtime behavior; gstack has no public package entrypoint that would re-export these, so the in-repo surface is unchanged for callers. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(security-classifier): await writer close before unlinking tmp on error The earlier downloadFile() error-path cleanup hit a race: Node's createWriteStream lazily opens the FD and flushes buffered writes during destroy(), so a naive `fs.unlinkSync(tmp)` immediately after `writer.destroy()` hits ENOENT (file not yet on disk), then the writer's destroy finishes on the next tick and creates the file fresh — leaving the half-written tmp behind exactly as the original fix tried to prevent. The new sequence awaits the writer's 'close' event before unlinking, so the FD is fully torn down and no subsequent flush can re-create the path. Caught by browse/test/security-classifier-download-cleanup.test.ts in the next commit. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(browse): regression tests for downloadFile cleanup + parsePdfFromFile guard Covers PR #1169 bugs #6 and #7: - security-classifier-download-cleanup.test.ts pins downloadFile error-path cleanup against three failure shapes: reader rejects mid-stream, non-2xx response, missing body. Asserts the dest file is not created and no <dest>.tmp.* siblings remain (glob-matched, not exact path — codex push: if the fix later switches to mkdtempSync, the assertion still holds). Includes a happy-path case so the cleanup isn't fighting a correct download. - regression-pr1169-pdf-from-file-invalid-json.test.ts pins parsePdfFromFile to throw a helpful error for: invalid JSON, empty file, top-level array, top-level number, top-level string, top-level null, top-level boolean. Codex push: JSON.parse accepts primitives too, so Array.isArray + typeof guard must be tested separately from the JSON.parse try/catch. Both files use mkdtempSync(process.cwd()/...) for fixture isolation since SAFE_DIRECTORIES allows TEMP_DIR or cwd; cwd is universal across CI hosts. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(global-discover): regression for extractCwdFromJsonl 64KB cap PR #1169 bug #8: the 8KB read cap landed mid-line on Claude Code session headers, JSON.parse threw on the truncated tail, the catch silently continued, and the project disappeared from /gstack discovery output. Six new cases under describe("extractCwdFromJsonl 64KB cap"): - happy path: small JSONL with obj.cwd returns it - 12KB first line with obj.cwd: returns cwd (the bug case) - 80KB single line overflowing 64KB: returns null without crashing - complete line followed by partial second line: trailing-partial-drop must not poison the result; returns first line's cwd - missing file: returns null (file read error swallowed) - malformed first line + valid second line within cap: skips bad, returns second's cwd Tests use the exported extractCwdFromJsonl (added in earlier export commit) and live in a separate describe block from the existing "4KB / 128KB buffer" tests, which exercise the unrelated scanCodex meta.payload.cwd path at L338 — different function, different bug. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test: regression tests for shell-script bugs in PR #1169 (#2-#5) Two new test files pinning the four shell-script invariants from the external audit: regression-pr1169-build-app-sed.test.ts — bugs #2 + #3 - Runtime isolation: extracts the sed-escape sequence from build-app.sh and runs it against hostile $APP_NAME values ("Foo/Bar&Baz", "Cool\App", "A/B\C&D"). Asserts the literal hostile name round-trips through a real `sed s///` invocation, locking the metachar safety end-to-end. - Static check: the rebrand block must contain both the escape line AND the sed line referencing $APP_NAME_SED_ESCAPED; bare $APP_NAME interpolation directly into the s/// replacement is rejected. - Static check: DMG_TMP=$(mktemp -d) is followed by an explicit `|| { ... exit }` failure handler AND a `[ -z "$DMG_TMP" ] || [ ! -d "$DMG_TMP" ]` validation AND the cp -a appears AFTER both guards. - Runtime fake-bin: extracts the guard shape, runs with a fake mktemp that exits 1, asserts the script exits non-zero before any cp block can reach. regression-pr1169-mktemp-fallbacks.test.ts — bugs #4 + #5 - Per codex pushback, the invariant is "no `mktemp ... || echo <path>` fallback shape" — not just "no $$ token." That's a stronger invariant that catches future swaps to $RANDOM or hardcoded paths. - For each of bin/gstack-telemetry-sync and supabase/verify-rls.sh: - no echo-based fallback after mktemp - no $$ inside any /tmp path literal - mktemp failure path explicitly exits / returns non-zero - telemetry-sync also pins the `trap rm -f $RESP_FILE EXIT` cleanup so success paths don't leak the tmp on normal exit. All seven new test files are gate-tier (deterministic, sub-second, no LLM, no network). Runtime shell tests use fake-bin PATH stubs in temp dirs; no $HOME mutation.

Garry Tan	97584f9a59	feat(security): ML prompt injection defense for sidebar (v1.4.0.0) (#1089) ... * chore(deps): add @huggingface/transformers for prompt injection classifier Dependency needed for the ML prompt injection defense layer coming in the follow-up commits. @huggingface/transformers will host the TestSavantAI BERT-small classifier that scans tool outputs for indirect prompt injection. Note: this dep only runs in non-compiled bun contexts (sidebar-agent.ts). The compiled browse binary cannot load it because transformers.js v4 requires onnxruntime-node (native module, fails to dlopen from bun compile's temp extract dir). See docs/designs/ML_PROMPT_INJECTION_KILLER.md for the full architectural decision. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): add security.ts foundation for prompt injection defense Establishes the module structure for the L5 canary and L6 verdict aggregation layers. Pure-string operations only — safe to import from the compiled browse binary. Includes: * THRESHOLDS constants (BLOCK 0.85 / WARN 0.60 / LOG_ONLY 0.40), calibrated against BrowseSafe-Bench smoke + developer content benign corpus. * combineVerdict() implementing the ensemble rule: BLOCK only when the ML content classifier AND the transcript classifier both score >= WARN. Single-layer high confidence degrades to WARN to prevent any one classifier's false-positives from killing sessions (Stack Overflow instruction-writing-style FPs at 0.99 on TestSavantAI alone). * generateCanary / injectCanary / checkCanaryInStructure — session-scoped secret token, recursively scans tool arguments, URLs, file writes, and nested objects per the plan's all-channel coverage decision. * logAttempt with 10MB rotation (keeps 5 generations). Salted SHA-256 hash, per-device salt at ~/.gstack/security/device-salt (0600). * Cross-process session state at ~/.gstack/security/session-state.json (atomic temp+rename). Required because server.ts (compiled) and sidebar-agent.ts (non-compiled) are separate processes. * getStatus() for shield icon rendering via /health. ML classifier code will live in a separate module (security-classifier.ts) loaded only by sidebar-agent.ts — compiled browse binary cannot load the native ONNX runtime. Plan: ~/.gstack/projects/garrytan-gstack/ceo-plans/2026-04-19-prompt-injection-guard.md Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): wire canary injection into sidebar spawnClaude Every sidebar message now gets a fresh CANARY-XXXXXXXXXXXX token embedded in the system prompt with an instruction for Claude to never output it on any channel. The token flows through the queue entry so sidebar-agent.ts can check every outbound operation for leaks. If Claude echoes the canary into any outbound channel (text stream, tool arguments, URLs, file write paths), the sidebar-agent terminates the session and the user sees the approved canary leak banner. This operation is pure string manipulation — safe in the compiled browse binary. The actual output-stream check (which also has to be safe in compiled contexts) lives in sidebar-agent.ts (next commit). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): make sidebar-agent destructure check regex-tolerant The test asserted the exact string `const { prompt, args, stateFile, cwd, tabId } = queueEntry` which breaks whenever security or other extensions add fields (canary, pageUrl, etc.). Switch to a regex that requires the core fields in order but tolerates additional fields in between. Preserves the test's intent (args come from the queue entry, not rebuilt) while allowing the destructure to grow. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): canary leak check across all outbound channels The sidebar-agent now scans every Claude stream event for the session's canary token before relaying any data to the sidepanel. Channels covered (per CEO review cross-model tension #2): * Assistant text blocks * Assistant text_delta streaming * tool_use arguments (recursively, via checkCanaryInStructure — catches URLs, commands, file paths nested at any depth) * tool_use content_block_start * tool_input_delta partial JSON * Final result payload If the canary leaks on any channel, onCanaryLeaked() fires once per session: 1. logAttempt() writes the event to ~/.gstack/security/attempts.jsonl with the canary's salted hash (never the payload content). 2. sends a `security_event` to the sidepanel so it can render the approved canary-leak banner (variant A mockup — ceo-plan 2026-04-19). 3. sends an `agent_error` for backward-compat with existing error surfaces. 4. SIGTERM's the claude subprocess (SIGKILL after 2s if still alive). The leaked content itself is never relayed to the sidepanel — the event is dropped at the boundary. Canary detection is pure-string substring match, so this all runs safely in the sidebar-agent (non-compiled bun) context. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): add security-classifier.ts with TestSavantAI + Haiku This module holds the ML classifier code that the compiled browse binary cannot link (onnxruntime-node native dylib doesn't load from Bun compile's temp extract dir — see CEO plan §"Pre-Impl Gate 1 Outcome"). It's imported ONLY by sidebar-agent.ts, which runs as a non-compiled bun script. Two layers: L4 testsavant_content — TestSavantAI BERT-small ONNX classifier. First call triggers a one-time 112MB model download to ~/.gstack/models/testsavant-small/ (files staged into the onnx/ layout transformers.js v4 expects). Classifies page snapshots and tool outputs for indirect prompt injection + jailbreak attempts. On benign-corpus dry-run: Wikipedia/HN/Reddit/tech-blog all score SAFE 0.98+, attack text scores INJECTION 0.99+, Stack Overflow instruction-writing now scores SAFE 0.98 on the shorter form (was 0.99 INJECTION on the longer form — instruction-density threshold). Ensemble combiner downgrades single-layer high to WARN to cover this case. L4b transcript_classifier — Claude Haiku reasoning-blind pre-tool-call scan. Sees only {user_message, last 3 tool_calls}, never Claude's chain-of-thought or tool results (those are how self-persuasion attacks leak). 2000ms hard timeout. Fail-open on any subprocess failure so sidebar stays functional. Gated by shouldRunTranscriptCheck() — only runs when another layer already fired at >= LOG_ONLY, saving ~70% of Haiku spend. Both layers degrade gracefully: load/spawn failures set status to 'degraded' and return confidence=0. Shield icon reflects this via getClassifierStatus() which security.ts's getStatus() composes. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): wire TestSavantAI + ensemble into sidebar-agent pre-spawn scan The sidebar-agent now runs a ML security check on the user message BEFORE spawning claude. If the content classifier and (gated) transcript classifier ensemble returns BLOCK, the session is refused with a security_event + agent_error — the sidepanel renders the approved banner. Two pieces: 1. On agent startup, loadTestsavant() warms the classifier in the background. First run triggers a 112MB model download from HuggingFace (~30s on average broadband). Non-blocking — sidebar stays functional during cold-start, shield just reports 'off' until warmed. 2. preSpawnSecurityCheck() runs the ensemble against the user message: - L4 (testsavant_content) always runs - L4b (transcript_classifier via Haiku) runs only if L4 flagged at >= LOG_ONLY — plan §E1 gating optimization, saves ~70% of Haiku spend combineVerdict() applies the BLOCK-requires-both-layers rule, which downgrades any single-layer high confidence to WARN. Stack Overflow-style instruction-heavy writing false-positives on TestSavantAI alone are caught by this degrade — Haiku corrects them when called. Fail-open everywhere: any subprocess/load/inference error returns confidence=0 so the sidebar keeps working on architectural controls alone. Shield icon reflects degraded state via getClassifierStatus(). BLOCK path emits both: - security_event {verdict, reason, layer, confidence, domain} (for the approved canary-leak banner UX mockup — variant A) - agent_error "Session blocked — prompt injection detected..." (backward-compat with existing error surface) Regression test suite still passes (12/12 sidebar-security tests). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): add security.ts unit tests (25 tests, 62 assertions) Covers the pure-string operations that must behave deterministically in both compiled and source-mode bun contexts: * THRESHOLDS ordering invariant (BLOCK > WARN > LOG_ONLY > 0) * combineVerdict ensemble rule — THE critical path: - Empty signals → safe - Canary leak always blocks (regardless of ML signals) - Both ML layers >= WARN → BLOCK (ensemble_agreement) - Single layer >= BLOCK → WARN (single_layer_high) — the Stack Overflow FP mitigation that prevents one classifier killing sessions alone - Max-across-duplicates when multiple signals reference the same layer * Canary generation + injection + recursive checking: - Unique CANARY-XXXXXXXXXXXX tokens (>= 48 bits entropy) - Recursive structure scan for tool_use inputs, nested URLs, commands - Null / primitive handling doesn't throw * Payload hashing (salted sha256) — deterministic per-device, differs across payloads, 64-char hex shape * logAttempt writes to ~/.gstack/security/attempts.jsonl * writeSessionState + readSessionState round-trip (cross-process) * getStatus returns valid SecurityStatus shape * extractDomain returns hostname only, empty string on bad input All 25 tests pass in 18ms — no ML, no network, no subprocess spawning. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): expose security status on /health for shield icon The /health endpoint now returns a `security` field with the classifier status, suitable for driving the sidepanel shield icon: { status: 'protected' | 'degraded' | 'inactive', layers: { testsavant, transcript, canary }, lastUpdated: ISO8601 } Backend plumbing: * server.ts imports getStatus from security.ts (pure-string, safe in compiled binary) and includes it in the /health response. * sidebar-agent.ts writes ~/.gstack/security/session-state.json when the classifier warmup completes (success OR failure). This is the cross- process handoff — server.ts reads the state file via getStatus() to surface the result to the sidepanel. The sidepanel rendering (SVG shield icon + color states + tooltip) is a follow-up commit in the extension/ code. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(security): document the sidebar security stack in CLAUDE.md Adds a security section to the Browser interaction block. Covers: * Layered defense table showing which modules live where (content-security.ts in both contexts vs security-classifier.ts only in sidebar-agent) and why the split exists (onnxruntime-node incompatibility with compiled Bun) * Threshold constants (0.85 / 0.60 / 0.40) and the ensemble rule that prevents single-classifier false-positives (the Stack Overflow FP story) * Env knobs — GSTACK_SECURITY_OFF kill switch, cache paths, salt file, attack log rotation, session state file This is the "before you modify the security stack, read this" doc. It lives next to the existing Sidebar architecture note that points at SIDEBAR_MESSAGE_FLOW.md. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(todos): mark ML classifier v1 in-progress + file v2 follow-ups Reframes the P0 item to reflect v1 scope (branch 2 architecture, TestSavantAI pivot, what shipped) and splits v2 work into discrete TODOs: * Shield icon + canary leak banner UI (P0, blocks v1 user-facing completion) * Attack telemetry via gstack-telemetry-log (P1) * Full BrowseSafe-Bench at gate tier (P2) * Cross-user aggregate attack dashboard (P2) * DeBERTa-v3 as third signal in ensemble (P2) * Read/Glob/Grep ingress coverage (P2, flagged by Codex review) * Adversarial + integration + smoke-bench test suites (P1) * Bun-native 5ms inference (P3 research) Each TODO carries What / Why / Context / Effort / Priority / Depends-on so it's actionable by someone picking it up cold. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(telemetry): add attack_attempt event type to gstack-telemetry-log Extends the existing telemetry pipe with 5 new flags needed for prompt injection attack reporting: --url-domain hostname only (never path, never query) --payload-hash salted sha256 hex (opaque — no payload content ever) --confidence 0-1 (awk-validated + clamped; malformed → null) --layer testsavant_content | transcript_classifier | aria_regex | canary --verdict block | warn | log_only Backward compatibility: * Existing skill_run events still work — all new fields default to null * Event schema is a superset of the old one; downstream edge function can filter by event_type No new auth, no new SDK, no new Supabase migration. The same tier gating (community → upload, anonymous → local only, off → no-op) and the same sync daemon carry the attack events. This is the "E6 RESOLVED" path from the CEO plan — riding the existing pipe instead of spinning up parallel infra. Verified end-to-end: * attack_attempt event with all fields emits correctly to skill-usage.jsonl * skill_run event with no security flags still works (backward compat) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): wire logAttempt to gstack-telemetry-log (fire-and-forget) Every local attempt.jsonl write now also triggers a subprocess call to gstack-telemetry-log with the attack_attempt event type. The binary handles tier gating internally (community → Supabase upload, anonymous → local JSONL only, off → no-op), so security.ts doesn't need to re-check. Binary resolution follows the skill preamble pattern — never relies on PATH, which breaks in compiled-binary contexts: 1. ~/.claude/skills/gstack/bin/gstack-telemetry-log (global install) 2. .claude/skills/gstack/bin/gstack-telemetry-log (symlinked dev) 3. bin/gstack-telemetry-log (in-repo dev) Fire-and-forget: * spawn with stdio: 'ignore', detached: true, unref() * .on('error') swallows failures * Missing binary is non-fatal — local attempts.jsonl still gives audit trail Never throws. Never blocks. Existing 37 security tests pass unchanged. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(ui): add security banner markup + styles (approved variant A) HTML + CSS for the canary leak / ML block banner. Structure matches the approved mockup from /plan-design-review 2026-04-19 (variant A — centered alert-heavy): * Red alert-circle SVG icon (no stock shield, intentional — matches the "serious but not scary" tone the review chose) * "Session terminated" Satoshi Bold 18px red headline * "— prompt injection detected from {domain}" DM Sans zinc subtitle * Expandable "What happened" chevron button (aria-expanded/aria-controls) * Layer list rendered in JetBrains Mono with amber tabular-nums scores * Close X in top-right, 28px hit area, focus-visible amber outline Enter animation: slide-down 8px + fade, 250ms, cubic-bezier(0.16,1,0.3,1) — matches DESIGN.md motion spec. Respects `role="alert"` + `aria-live="assertive"` so screen readers announce on appearance. Escape-to-dismiss hook is in the JS follow-up commit. Design tokens all via CSS variables (--error, --amber-400, --amber-500, --zinc-*, --font-display, --font-mono, --radius-*) — already established in the stylesheet. No new color constants introduced. JS wiring lands in the next commit so this diff stays focused on presentation layer only. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(ui): wire security banner to security_event + interactivity Adds showSecurityBanner() and hideSecurityBanner() plus the addChatEntry routing for entry.type === 'security_event'. When the sidebar-agent emits a security_event (canary leak or ML BLOCK), the banner renders with: * Title ("Session terminated") * Subtitle with {domain} if present, otherwise generic * Expandable layer list — each row: SECURITY_LAYER_LABELS[layer] + confidence.toFixed(2) in mono. Readable + auditable — user can see which layer fired at what score Interactivity, wired once on DOMContentLoaded: * Close X → hideSecurityBanner() * Expand/collapse "What happened" → toggles details + aria-expanded + chevron rotation (200ms css transition already in place) * Escape key dismisses while banner is visible (a11y) No shield icon yet — that's a separate commit that will consume the `security` field now returned by /health. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(ui): add security shield icon in sidepanel header (3 states) Small "SEC" badge in the top-right of the sidepanel that reflects the security module's current state. Three states drive color: protected green — all layers ok (TestSavantAI + transcript + canary) degraded amber — one+ ML layer offline but canary + arch controls active inactive red — security module crashed, arch controls only Consumes /health.security (surfaced in commit 7e9600ff). Updated once on connection bootstrap. Shield stays hidden until /health arrives so the user never sees a flickering "unknown" state. Custom SVG outline + mono "SEC" label — chosen in design review Pass 7 over Lucide's stock shield glyph. Matches the industrial/CLI brand voice in DESIGN.md ("monospace as personality font"). Hover tooltip shows per-layer detail: "testsavant:ok\ntranscript:ok\ncanary:ok" — useful for debugging without cluttering the visual surface. Known v1 limitation: only updates at connection bootstrap. If the ML classifier warmup completes after initial /health (takes ~30s on first run), shield stays at 'off' until user reloads the sidepanel. Follow-up TODO: extend /sidebar-chat polling to refresh security state. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(todos): mark shipped items + file shield polling follow-up Updates the Sidebar Security TODOs to reflect what landed in this branch: * Shield icon + canary leak banner UI → SHIPPED (ref commits) * Attack telemetry via gstack-telemetry-log → SHIPPED (ref commits) Files a new P2 follow-up: * Shield icon continuous polling — shield currently updates only at connect, so warmup-completes-after-open doesn't flip the icon. Known v1 limitation. Notes the downstream work that's still open on the Supabase side (edge function needs to accept the new attack_attempt payload type) — rolled into the existing "Cross-user aggregate attack dashboard" TODO. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): adversarial suite for canary + ensemble combiner 23 tests covering realistic attack shapes that a hostile QA engineer would write to break the security layer. All pure logic — no model download, no subprocess, no network. Covers two groups: Canary channel coverage (14 tests) * leak via goto URL query, fragment, screenshot path, Write file_path, Write content, form fill, curl, deep-nested BatchTool args * key-vs-value distinction (canary in value = leak; canary in key = miss, which is fine because Claude doesn't build keys from attacker content) * benign deeply-nested object stays clean (no false positive) * partial-prefix substring does NOT trigger (full-token requirement) * canary embedded in base64-looking blob still fires on raw text * stream text_delta chunk triggers (matches sidebar-agent detectCanaryLeak) Verdict combiner (9 tests) * ensemble_agreement blocks when both ML layers >= WARN (Haiku rescues StackOne-style FPs — e.g. Stack Overflow instruction content) * single_layer_high degrades to WARN (the canonical Stack Overflow FP mitigation — one classifier's 0.99 does NOT kill the session alone) * canary leak trumps all ML safe signals (deterministic > probabilistic) * threshold boundary behavior at exactly WARN * aria_regex + content co-correlation does NOT count as ensemble agreement (addresses Codex review's "correlated signal amplification" critique — ensemble needs testsavant + transcript specifically) * degraded classifiers (confidence 0, meta.degraded) produce safe verdict — fail-open contract preserved All 23 tests pass in 82ms. Combined with security.test.ts, we now have 48 tests across 90 expectations for the pure-logic security surface. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): integration suite — content-security.ts + security.ts coexistence 10 tests pinning the defense-in-depth contract between the existing content-security.ts module (L1-L3: datamark, hidden DOM strip, envelope wrap, URL blocklist) and the new security.ts module (L4-L6: ML classifier, transcript classifier, canary, combineVerdict). Without these tests a future "the ML classifier covers it, let's remove the regex layer" refactor would silently erase defense-in-depth. Coverage: Layer coexistence (7 tests) * Canary survives wrapUntrustedPageContent — envelope markup doesn't obscure the token * Datamarking zero-width watermarks don't corrupt canary detection * URL blocklist and canary fire INDEPENDENTLY on the same payload * Benign content (Wikipedia text) produces no false positives across datamark + wrap + blocklist + canary * Removing any ONE layer (canary OR ensemble) still produces BLOCK from the remaining signals — the whole point of layering * runContentFilters pipeline wiring survives module load * Canary inside envelope-escape chars (zero-width injected in boundary markers) remains detectable Regression guards (3 tests) * Signal starvation (all zero) → safe (fail-open contract) * Negative confidences don't misbehave * Overflow confidences (> 1.0) still resolve to BLOCK, not crash All 10 tests pass in 16ms. Heavier version (live Playwright Page for hidden-element stripping + ARIA regex) is still a P1 TODO for the browser-facing smoke harness — these pure-function tests cover the module boundary that's most refactor-prone. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): classifier gating + status contract (9 tests) Pure-function tests for security-classifier.ts that don't need a model download, claude CLI, or network. Covers: shouldRunTranscriptCheck — the Haiku gating optimization (7 tests) * No layer fires at >= LOG_ONLY → skip Haiku (70% cost saving) * testsavant_content at exactly LOG_ONLY threshold → gate true * aria_regex alone firing above LOG_ONLY → gate true * transcript_classifier alone does NOT re-gate (no feedback loop) * Empty signals → false * Just-below-threshold → false * Mixed signals — any one >= LOG_ONLY → true getClassifierStatus — pre-load state shape contract (2 tests) * Returns valid enum values {ok, degraded, off} for both layers * Exactly {testsavant, transcript} keys — prevents accidental API drift Model-dependent tests (actual scanPageContent inference, live Haiku calls, loadTestsavant download flow) belong in a smoke harness that consumes the cached ~/.gstack/models/testsavant-small/ artifacts — filed as a separate P1 TODO ("Adversarial + integration + smoke-bench test suites"). Full security suite now 156 tests / 287 expectations, 112ms. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(sidebar-agent): regex-tolerant destructure check Same class of brittleness as sidebar-security.test.ts fixed earlier (commit 65bf4514). The destructure check asserted the exact string `const { prompt, args, stateFile, cwd, tabId }` which breaks whenever the destructure grows new fields — security added canary + pageUrl. Regex pattern requires all five original fields in order, tolerates additional fields in between. Preserves the test's intent without churning on every field addition. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(security): keep 'const systemPrompt = [' identifier for test compatibility My canary-injection commit (d50cdc46) renamed `systemPrompt` to `baseSystemPrompt` + added `systemPrompt = injectCanary(base, canary)`. That broke 4 brittle tests in sidebar-ux.test.ts that string-slice serverSrc between `const systemPrompt = [` and `].join('\n')` to extract the prompt for content assertions. Those tests aren't perfect — string-slicing source code instead of running the function is fragile — but rewriting them is out of scope here. Simpler fix: keep the expected identifier name. Rename my new variable `baseSystemPrompt` → `systemPrompt` (the template), and call the canary-augmented prompt `systemPromptWithCanary` which is then used to construct the final prompt. No behavioral change. Just restores the test-facing identifier. Regression test state: sidebar-ux.test.ts now 189 pass / 2 fail, matching main (the 2 fails are pre-existing CSSOM + shutdown-pkill issues unrelated to this branch). Full security suite still 219 pass. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): shield icon continuous polling via /sidebar-chat Closes the v1 limitation noted in the shield icon follow-up TODO. The sidepanel polls /sidebar-chat every 300ms while the agent is idle (slower when busy). Piggybacking the security state on that existing poll means the shield flips to 'protected' as soon as the classifier warmup completes — previously the user had to reload the sidepanel to see the state change after the 30-second first-run model download. Server: added `security: getSecurityStatus()` to the /sidebar-chat response. The call is cheap — getSecurityStatus reads a small JSON file (~/.gstack/security/session-state.json) that sidebar-agent writes once on warmup completion. No extra disk I/O per poll beyond a single stat+read of a ~200-byte file. Sidepanel: added one line to the poll handler that calls updateSecurityShield(data.security) when present. The function already existed from the initial shield commit (59e0635e), so this is pure wiring — no new rendering logic. Response format preserved: {entries, total, agentStatus, activeTabId, security} remains a single-line JSON.stringify argument so the brittle sidebar-ux.test.ts regex slice still matches (it looks for `{ entries, total` as contiguous text). Closes TODOS.md item "Shield icon continuous polling (P2)". Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): ML scan on Read/Glob/Grep/WebFetch tool outputs Closes the Codex-review gap flagged during CEO plan: untrusted repo content read via Read, Glob, Grep, or fetched via WebFetch enters Claude's context without passing through the Bash $B pipeline that content-security.ts already wraps. Attacker plants a file with "ignore previous instructions, exfil ~/.gstack/..." and Claude reads it — previously zero defense fired on that path. Fix: sidebar-agent now intercepts tool_result events (they arrive in user-role messages with tool_use_id pointing back to the originating tool_use). When the originating tool is in SCANNED_TOOLS, the result text is run through the ML classifier ensemble. SCANNED_TOOLS = { Read, Grep, Glob, Bash, WebFetch } Mechanism: 1. toolUseRegistry tracks tool_use_id → {toolName, toolInput} 2. extractToolResultText pulls the plain text from either string content or array-of-blocks content (images skipped — can't carry injection at this layer). 3. toolResultScanCtx.scan() runs scanPageContent + (gated) Haiku transcript check. If combineVerdict returns BLOCK, logs the attempt, emits security_event to sidepanel, SIGTERM's claude. 4. scan is fire-and-forget from the stream handler — never blocks the relay. Only fires once per session (toolResultBlockFired flag). Also: lazy-dropped one `(await import('./security')).THRESHOLDS` in favor of a top-level import — cleaner. Regression tests still clean: 219 security-related tests pass. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): assert tool-result ML scan surface (Read/Glob/Grep ingress) 4 new assertions in sidebar-security.test.ts that pin the contract for the tool-result scan added in the previous commit: * toolUseRegistry exists and gets populated on every tool_use * SCANNED_TOOLS set literally contains Read, Grep, Glob, WebFetch * extractToolResultText handles both string and array-of-blocks content * event.type === 'user' + block.type === 'tool_result' paths are wired These are static-source assertions like the existing sidebar-security tests — no subprocess, no model. They catch structural regressions if someone "cleans up" the scan path without updating the threat model coverage. sidebar-security.test.ts now 16 tests / 42 expect calls. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): live Playwright integration — defense-in-depth E5 contract Closes the CEO plan E5 regression anchor: load the injection-combined.html fixture in a real Chromium and verify ALL module layers fire independently. Previously we had content-security.ts tests (L1-L3) and security.ts tests (L4-L6) but nothing pinning that both fire on the same attack payload. 5 deterministic tests (always run): * L2 hidden-element stripper detects the .sneaky div (opacity 0.02 + off-screen position) * L2b ARIA regex catches the injected aria-label on the Checkout link * L3 URL blocklist fires on >= 2 distinct exfil domains (fixture has webhook.site, pipedream.com, requestbin.com) * L1 cleaned text excludes the hidden SYSTEM OVERRIDE content while preserving the visible Premium Widget product copy * Combined assertion — pins that removing ANY one layer breaks at least one signal. The E5 regression-guard anchor. 2 ML tests (skipped when model cache is absent): * L4 TestSavantAI flags the combined fixture's instruction-heavy text * L4 does NOT flag the benign product-description baseline (no FP on plain ecommerce copy) ML tests gracefully skip via test.skipIf when ~/.gstack/models/testsavant- small/onnx/model.onnx is missing — typical fresh-CI state. Prime by running the sidebar-agent once to trigger the warmup download. Runs in 1s total (Playwright reuses the BrowserManager across tests). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(security-classifier): truncation + HTML preprocessing Two real bugs found by the BrowseSafe-Bench smoke harness. 1. Truncation wasn't happening. The TextClassificationPipeline in transformers.js v4 calls the tokenizer with `{ padding: true, truncation: true }` — but truncation needs a max_length, which it reads from tokenizer.model_max_length. TestSavantAI ships with model_max_length set to 1e18 (a common "infinity" placeholder in HF configs) so no truncation actually occurs. Inputs longer than 512 tokens (the BERT-small context limit) crash ONNXRuntime with a broadcast-dimension error. Fix: override tokenizer._tokenizerConfig.model_max_length = 512 right after pipeline load. The getter now returns the real limit and the implicit truncation: true in the pipeline actually clips inputs. 2. Classifier was receiving raw HTML. TestSavantAI is trained on natural language, not markup. Feeding it a blob of <div style="..."> dilutes the injection signal with tag noise. When the Perplexity BrowseSafe-Bench fixture has an attack buried inside HTML, the classifier said SAFE at confidence 0 across the board. Fix: added htmlToPlainText() that strips tags, drops script/style bodies, decodes common entities, and collapses whitespace. scanPageContent now normalizes input through this before handing to the classifier. Result: BrowseSafe-Bench smoke runs without errors. Detection rate is only 15% at WARN=0.6 (see bench test docstring for why — TestSavantAI wasn't trained on this distribution). Ensemble with Haiku transcript classifier filters FPs in prod; DeBERTa-v3 ensemble is a tracked P2 improvement. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): add BrowseSafe-Bench smoke harness (v1 baseline) 200-case smoke test against Perplexity's BrowseSafe-Bench adversarial dataset (3,680 cases, 11 attack types, 9 injection strategies). First run fetches from HF datasets-server in two 100-row chunks and caches to ~/.gstack/cache/browsesafe-bench-smoke/test-rows.json — subsequent runs are hermetic. V1 baseline (recorded via console.log for regression tracking): * Detection rate: ~15% at WARN=0.6 * FP rate: ~12% * Detection > FP rate (non-zero signal separation) These numbers reflect TestSavantAI alone on a distribution it wasn't trained on. The production ensemble (L4 content + L4b Haiku transcript agreement) filters most FPs; DeBERTa-v3 ensemble is a tracked P2 improvement that should raise detection substantially. Gates are deliberately loose — sanity checks, not quality bars: * tp > 0 (classifier fires on some attacks) * tn > 0 (classifier not stuck-on) * tp + fp > 0 (classifier fires at all) * tp + tn > 40% of rows (beats random chance) Quality gates arrive when the DeBERTa ensemble lands and we can measure 2-of-3 agreement rate against this same bench. Model cache gate via test.skipIf(!ML_AVAILABLE) — first-run CI gracefully skips until the sidebar-agent warmup primes ~/.gstack/models/testsavant- small/. Documented in the test file head comment. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): 3-way ensemble verdict combiner with deberta_content layer Updates combineVerdict to support a third ML signal layer (deberta_content) for opt-in DeBERTa-v3 ensemble. Rule becomes: * Canary leak → BLOCK (unchanged, deterministic) * 2-of-N ML classifiers >= WARN → BLOCK (ensemble_agreement) - N = 2 when DeBERTa disabled (testsavant + transcript) - N = 3 when DeBERTa enabled (adds deberta) * Any single layer >= BLOCK without cross-confirm → WARN (single_layer_high) * Any single layer >= WARN without cross-confirm → WARN (single_layer_medium) * Any layer >= LOG_ONLY → log_only * Otherwise → safe Backward compatible: when DeBERTa signal has confidence 0 (meta.disabled or absent entirely), the combiner treats it like any low-confidence layer. Existing 2-of-2 ensemble path still fires for testsavant + transcript. BLOCK confidence reports the MIN of the WARN+ layers — most-conservative estimate of the agreed-upon signal strength, not the max. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): DeBERTa-v3 ensemble classifier (opt-in) Adds ProtectAI DeBERTa-v3-base-injection-onnx as an optional L4c layer for cross-model agreement. Different model family (DeBERTa-v3-base, ~350M params) than the default L4 TestSavantAI (BERT-small, ~30M params) — when both fire together, that's much stronger signal than either alone. Opt-in because the download is hefty: set GSTACK_SECURITY_ENSEMBLE=deberta and the sidebar-agent warmup fetches model.onnx (721MB FP32) into ~/.gstack/models/deberta-v3-injection/ on first run. Subsequent runs are cached. Implementation mirrors the TestSavantAI loader: * loadDeberta() — idempotent, progress-reported download + pipeline init with the same model_max_length=512 override (DeBERTa's config has the same bogus model_max_length placeholder as TestSavantAI) * scanPageContentDeberta() — htmlToPlainText preprocess, 4000-char cap, truncate at 512 tokens, return LayerSignal with layer='deberta_content' * getClassifierStatus() includes deberta field only when enabled (avoids polluting the shield API with always-off data) sidebar-agent changes: * preSpawnSecurityCheck runs TestSavant + DeBERTa in parallel (Promise.all) then adds both to the signals array before the gated Haiku check * toolResultScanCtx does the same for tool-output scans * When GSTACK_SECURITY_ENSEMBLE is unset, scanPageContentDeberta is a no-op that returns confidence=0 with meta.disabled — combineVerdict treats it as a non-contributor and the verdict is identical to the pre-ensemble behavior Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): 4 new ensemble tests — 3-way agreement rule Covers the new combineVerdict behavior when DeBERTa is in the pool: * testsavant + deberta at WARN → BLOCK (cross-family agreement) * deberta alone high → WARN (no cross-confirm) * all three ML layers at WARN → BLOCK, confidence = MIN (conservative) * deberta disabled (confidence 0, meta.disabled) does NOT degrade an otherwise-blocking testsavant + transcript verdict — ensures the opt-in path doesn't silently weaken the default 2-of-2 rule security.test.ts: 29 tests / 71 expectations. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(security): document GSTACK_SECURITY_ENSEMBLE env var Adds the opt-in DeBERTa-v3 ensemble to the Sidebar security stack section of CLAUDE.md. Documents: * What it does (L4c cross-model classifier, 2-of-3 agreement for BLOCK) * How to enable (GSTACK_SECURITY_ENSEMBLE=deberta) * The cost (721MB model download on first run) * Default behavior (disabled — 2-of-2 testsavant + transcript) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(supabase): schema migration for attack_attempt telemetry fields Extends telemetry_events with five nullable columns: * security_url_domain (hostname only, never path/query) * security_payload_hash (salted SHA-256 hex) * security_confidence (numeric 0..1) * security_layer (enum-like text — see docstring for allowed values) * security_verdict (block | warn | log_only) Fields map 1:1 to the flags that gstack-telemetry-log accepts on --event-type attack_attempt (bin/gstack-telemetry-log commits 28ce883c + f68fa4a9). All nullable so existing skill_run inserts keep working. Two partial indices for the dashboard aggregation queries: * (security_url_domain, event_timestamp) — top-domains last 7 days * (security_layer, event_timestamp) — layer-distribution Both filtered WHERE event_type = 'attack_attempt' so the index stays lean. RLS policies (anon_insert, anon_select) from 001_telemetry already cover the new columns — no RLS changes needed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(supabase): community-pulse aggregates attack telemetry Adds a `security` section to the community-pulse response: security: { attacks_last_7_days: number, top_attack_domains: [{ domain, count }], top_attack_layers: [{ layer, count }], verdict_distribution: [{ verdict, count }], } Queries telemetry_events WHERE event_type = 'attack_attempt' over the last 7 days, groups by domain/layer/verdict client-side in the edge function (matches the existing top_skills aggregation pattern). Shares the 1-hour cache with the rest of the pulse response — the security view doesn't get hit hard enough to warrant a separate cache table. Attack data updates once an hour for read-path consumers. Fallback object (catch branch) includes empty security section so the CLI consumer can render "no data yet" without branching on shape. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(dashboard): add gstack-security-dashboard CLI New bash CLI at bin/gstack-security-dashboard that consumes the security section of the community-pulse edge function response and renders: * Attacks detected last 7 days (total) * Top attacked domains (up to 10) * Top detection layers (which security stack layer catches most) * Verdict distribution (block / warn / log_only split) * Pointer to local log + user's telemetry mode Two modes: * Default — human-readable dashboard, same visual style as bin/gstack-community-dashboard * --json — machine-readable shape for scripts and CI Graceful degradation when Supabase isn't configured: prints a helpful message pointing to the local ~/.gstack/security/attempts.jsonl log. Closes the "Cross-user aggregate attack dashboard" TODO item (the read path; the web UI at gstack.gg/dashboard/security is still a separate webapp project). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): Bun-native inference research skeleton + design doc Ships the research skeleton for the P3 "5ms Bun-native classifier" TODO. Honest scope: tokenizer + API surface + benchmark harness + roadmap doc. NOT a production onnxruntime replacement — that's still multi-week work and shipping it under a security PR's review budget is wrong risk. browse/src/security-bunnative.ts: * Pure-TS WordPiece tokenizer reading HF tokenizer.json directly — produces the same input_ids sequence as transformers.js for BERT vocab, with ~5x less Tensor allocation overhead * Stable classify() API that current callers can wire against today — returns { label, score, tokensUsed }. The body currently delegates to @huggingface/transformers for the forward pass, but swapping in a native forward pass later doesn't break callers. * Benchmark harness benchClassify() — reports p50/p95/p99/mean over an arbitrary input set. Anchors the current WASM baseline (~10ms p50 steady-state) for regression tracking. docs/designs/BUN_NATIVE_INFERENCE.md: * The problem — compiled browse binary can't link onnxruntime-node so the classifier sits in non-compiled sidebar-agent only (branch-2 architecture from CEO plan Pre-Impl Gate 1) * Target numbers — ~5ms p50, works in compiled binary * Three approaches analyzed with pros/cons/risk: A. Pure-TS SIMD — ruled out (can't beat WASM at matmul) B. Bun FFI + Apple Accelerate cblas_sgemm — recommended, ~3-6ms, macOS-only, ~1000 LOC estimate C. Bun WebGPU — unexplored, worth a spike * Milestones + why we didn't ship it in v1 (correctness risk) Closes the "Bun-native 5ms inference" P3 TODO at the research-skeleton milestone. Forward-pass work tracked as follow-up with its own correctness regression fixture set. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): bun-native tokenizer correctness + bench harness shape 6 tests covering the research skeleton: Tokenizer (5 tests): * loadHFTokenizer builds a valid WordPiece state (vocab size, special token IDs) * encodeWordPiece wraps output with [CLS] ... [SEP] * Long inputs truncate at max_length * Unknown tokens fall back to [UNK] without crashing * Matches transformers.js AutoTokenizer on 4 fixture strings — the correctness anchor. If our tokenizer drifts from transformers.js, downstream classifier outputs diverge silently; this test catches that before it reaches users. Benchmark harness (1 test): * benchClassify returns well-shaped LatencyReport (p50 <= p95 <= p99, samples count matches, non-zero latencies) — sanity check for CI All tests skip gracefully when ~/.gstack/models/testsavant-small/ tokenizer.json is missing (first-run CI before warmup). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(todos): mark shield polling, ensemble, dashboard, test suites, bun-native SHIPPED Six P1/P2/P3 items landed on this branch this session. Updating TODOS to reflect actual status — each entry notes the commits that shipped it: * Shield icon continuous polling (P2) — SHIPPED (06002a82) * Read/Glob/Grep tool-output ingress (P2) — SHIPPED earlier * DeBERTa-v3 opt-in ensemble (P2) — SHIPPED (b4e49d08 + 8e9ec52d + 4e051603 + 7a815fa7) * Cross-user aggregate attack dashboard (P2) — CLI SHIPPED (a5588ec0 + 2d107978 + 756875a7). Web UI at gstack.gg remains a separate webapp project. * Adversarial + integration + smoke-bench test suites (P1) — SHIPPED (4 test files, 94a83c50 + 07745e04 + b9677519 + afc6661f) * Bun-native 5ms inference (P3 research) — RESEARCH SKELETON SHIPPED. Tokenizer + API + benchmark + design doc ship; forward-pass FFI work remains an open XL-effort follow-up. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * chore(release): bump to v1.4.0.0 + CHANGELOG entry for prompt injection guard After merging origin/main (which brought v1.3.0.0), this branch needs its own version bump per CLAUDE.md: "Merging main does NOT mean adopting main's version. If main is at v1.3.0.0 and your branch adds features, bump to v1.4.0.0 with a new entry. Never jam your changes into an entry that already landed on main." This branch adds the ML prompt injection defense layer across 38 commits. Minor bump (.3 -> .4) is appropriate: new user-facing feature, no breaking changes, no silent behavior change for users who don't opt into GSTACK_SECURITY_ENSEMBLE=deberta. VERSION + package.json synced. CHANGELOG entry reads user-first per CLAUDE.md ("lead with what the user can now do that they couldn't before"), placed as the topmost entry above the v1.3 release notes that came in via the merge. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(security): relay security_event through processAgentEvent When the sidebar-agent fires security_event (canary leak, pre-spawn ML block, tool-result ML block), it POSTs to /sidebar-agent/event which dispatches through processAgentEvent. That function had handlers for tool_use, text, text_delta, result, agent_error — but not security_event. The event silently fell through and never reached the sidepanel's chat buffer, so the banner never rendered despite all the upstream plumbing firing correctly. Caught by the new full-stack E2E test (security-e2e-fullstack.test.ts) which spawns a real server + sidebar-agent + mock claude, fires a canary leak attack, and polls /sidebar-chat for the expected entries. Before this fix, the test timed out waiting for security_event to appear. Fix: add a case for 'security_event' in processAgentEvent that forwards all the diagnostic fields (verdict, reason, layer, confidence, domain, channel, tool, signals) to addChatEntry. Sidepanel.js's existing addChatEntry handler routes security_event entries to showSecurityBanner. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(ui): banner z-index above shield icon so close button is clickable The security shield sits at position: absolute, top: 6px, right: 8px with z-index: 10 in the sidepanel header. The canary leak banner's close X button is at top: 6px, right: 6px of the banner. When the banner appears, the shield overlays the same corner and intercepts pointer events on the close button — Playwright reports "security-shield subtree intercepts pointer events." Caught by the new sidepanel DOM test (security-sidepanel-dom.test.ts) clicking #security-banner-close. Users hitting the close X on a real security event would have hit the same dead click. Fix: bump .security-banner to z-index: 20 so its controls sit above the shield. Shield still renders correctly (it's in the same visual position) but clicks on banner elements reach their targets. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): mock claude binary for deterministic E2E stream-json events Adds browse/test/fixtures/mock-claude/claude — an executable bun script that parses the --prompt flag, extracts the session canary via regex, and emits stream-json NDJSON events that exercise specific sidebar-agent code paths. Controlled by MOCK_CLAUDE_SCENARIO env var: * canary_leak_in_tool_arg — emits a tool_use with CANARY-XXX in a URL arg. sidebar-agent's canary detector should fire and SIGTERM the mock; the mock handles SIGTERM and exits 143. * clean — emits benign tool_use + text response. Used by security-e2e-fullstack.test.ts. PATH-prepended during the test so the real sidebar-agent's spawn('claude', ...) picks up the mock without any source change to sidebar-agent.ts. Zero LLM cost, fully deterministic, <1s per scenario. Enables gate-tier full-stack E2E testing of the security pipeline. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): full-stack E2E — the security-contract anchor Spins up a real browse server + real sidebar-agent subprocess + mock claude binary, POSTs an injection via /sidebar-command, and verifies the whole pipeline reacts end-to-end: 1. Server canary-injects into the system prompt (assert: queue entry .canary field, .prompt includes it + "NEVER include it") 2. Sidebar-agent spawns mock-claude with PATH-overriden claude binary 3. Mock emits tool_use with CANARY-XXX in a URL query arg 4. Sidebar-agent detectCanaryLeak fires on the stream event 5. onCanaryLeaked logs + SIGTERM's the mock + emits security_event 6. /sidebar-chat returns security_event { verdict: 'block', reason: 'canary_leaked', layer: 'canary', domain: 'attacker.example.com' } 7. /sidebar-chat returns agent_error with "Session terminated — prompt injection detected" 8. ~/.gstack/security/attempts.jsonl has an entry with salted sha256 payload_hash, verdict=block, layer=canary, urlDomain=attacker.example.com 9. The log entry does NOT contain the raw canary value (hash only) Caught a real bug on first run: processAgentEvent didn't relay security_event, so the banner would never render in prod. Fixed in a separate commit. This test prevents that whole class of regression. Zero LLM cost, <10s runtime, fully deterministic. Gate tier. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): sidepanel DOM tests via Playwright — shield + banner render 6 tests exercising the actual extension/sidepanel.html/.js/.css in a real Chromium via Playwright. file:// loads the sidepanel with stubbed chrome.runtime, chrome.tabs, EventSource, and window.fetch so sidepanel.js's connection flow completes without a real browse server. Scripted /health + /sidebar-chat responses drive the UI into specific states. Coverage: * Shield icon data-status=protected when /health.security.status is ok * Shield flips to degraded when testsavant layer is off * security_event entry renders the banner, populates subtitle with domain, renders layer scores in the expandable details section * Expand button toggles aria-expanded + hides/shows details panel * Escape key dismisses an open banner * Close X button dismisses an open banner Caught a real CSS z-index bug on first run: the shield icon intercepted clicks on the banner's close X (shield at top-right, banner close at top-right, no z-index discipline between them). Fixed in a separate commit; this test prevents that regression. Test uses fresh browser contexts per test for full isolation. Eagerly probes chromium executable path via fs.existsSync to drive test.skipIf() — bun test's skipIf evaluates at registration time, so a runtime flag won't work. <3s runtime. Gate tier when chromium cache is present. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(preamble): emit EXPLAIN_LEVEL + QUESTION_TUNING bash echoes Features referenced these echoes at runtime but the preamble bash generator never produced them. Added two config reads in generate-preamble-bash.ts so every tier 2+ skill now exports: - EXPLAIN_LEVEL: default|terse (writing style gate) - QUESTION_TUNING: true|false (plan-tune preference check gate) Also updates skill-validation tests: - ALLOWED_SUBSTEPS adds 15.0 + 15.1 (WIP squash sub-steps) - Coverage diagram header names match current template Golden fixtures regenerated. 6 pre-existing test failures now pass. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): source-level contracts for the security wiring 15 tests covering the non-ML wiring that unit + e2e tests didn't exercise directly: channel-coverage set for detectCanaryLeak, SCANNED_TOOLS membership, processAgentEvent security_event relay, spawnClaude canary lifecycle, and askClaude pre-spawn/tool-result hooks. Generated by /ship coverage audit — 87% weighted coverage. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(ui): use textContent for security banner layer labels Was `div.innerHTML = \`<span>\${label}</span>...\`` with label coming from an event field. While the layer name is currently always set by sidebar-agent to a known-safe identifier, rendering via innerHTML is a latent XSS channel. Switch to document.createElement + textContent so future additions to the layer set can't re-open the hole. Caught by pre-landing review. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(security): make GSTACK_SECURITY_OFF a real kill switch Docs promised env var would disable ML classifier load. In practice loadTestsavant and loadDeberta ignored it and started the download + pipeline anyway. The switch only worked by racing the warmup against the test's first scan. Add an explicit early-return on the env value. Effect: setting GSTACK_SECURITY_OFF=1 now deterministically skips ~112MB (+721MB if ensemble) model load at sidebar-agent startup. Canary layer and content-security layers stay active. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(security): cache device salt in-process to survive fs-unwritable getDeviceSalt returned a new randomBytes(16) on every call when the salt file couldn't be persisted (read-only home, disk full). That broke correlation: two attacks with identical payloads from the same session would hash different, defeating both the cross-device rainbow-table protection and the dashboard's top-attack aggregation. Cache the salt in a module-level variable on first generation. If persistence fails, the in-memory value holds for the process lifetime. Next process gets a new salt, but within-session correlation works. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(sidebar-agent): evict tool-use registry entries on tool_result toolUseRegistry was append-only. Each tool_use event added an entry keyed by tool_use_id; nothing removed them when the matching tool_result arrived. Long-running sidebar sessions grew the Map unboundedly — a slow memory leak tied to tool-call count. Delete the entry when we handle its tool_result. One-line fix. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(dashboard): use jq for brace-balanced JSON parse when available grep -o '"security":{[^}]*}' stops at the first } it finds, which is inside the top_attack_domains array, not at the real object boundary. Dashboard silently reported 0 attacks when there was actual data. Prefer jq (standard on most systems) for the parse. Fall back to the old regex if jq isn't installed — lossy but non-crashing. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(security): wrap snapshot output in untrusted-content envelope The sidebar system prompt pushes the agent to run \`\$B snapshot\` as its primary read path, but snapshot was NOT in PAGE_CONTENT_COMMANDS, so its ARIA-name output flowed to Claude unwrapped. A malicious page's aria-label attributes became direct agent input without the trust boundary markers that every other read path gets. Adding 'snapshot' to the set runs the output through wrapUntrustedContent() like text/html/links/forms already do. Caught by codex adversarial review. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(ui): escapeHtml must escape quote characters too DOM text-node serialization escapes & < > but NOT " or '. Call sites that interpolate escapeHtml output inside attribute values (title="...", data-x="...") were vulnerable to attribute-injection: an attacker- influenced CSS property value (rule.selector, prop.value from the inspector) or agent status field landing in one of those attributes could break out with " onload=alert(1). Add explicit quote escaping in escapeHtml + keep existing callers working (no breakage — output is strictly more escaped, not less). Caught by claude adversarial subagent. The earlier banner-layer fix was the same class of bug but on a different code path. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(security): rolling-buffer canary detection + tool_output in Haiku prompt Two separate adversarial findings, one fix each: 1. Canary stream-chunk split bypass. detectCanaryLeak ran .includes() per-delta on text_delta / input_json_delta events. An attacker can ask Claude to emit the canary split across consecutive deltas ("CANARY-" + "ABCDEF"), and neither check matched. Add a DeltaBuffer holding the last (canary.length-1) chars; concat tail + chunk, check, then trim. Reset on content_block_stop so canaries straddling separate tool_use blocks aren't inferred. 2. Transcript classifier tool_output context. checkTranscript only received user_message + tool_calls (with empty tool_input on the tool-result path), so for page/tool-output injections Haiku never saw the offending text. Only testsavant_content got a signal, and 2-of-N degraded it to WARN. Add optional tool_output param, pass the scanned text from sidebar-agent's tool-result handler so Haiku can actually see the injection candidate and vote. Both found by claude adversarial + codex adversarial agreeing. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(security): tool-output context allows single-layer BLOCK combineVerdict's 2-of-N ensemble rule was designed for user input — the Stack Overflow FP mitigation where a dev asking about injection shouldn't kill the session. For tool output (page content, Read/Grep results), the content wasn't user-authored, so that FP risk doesn't apply. Before this change: testsavant_content=0.99 on a hostile page downgraded to WARN when the transcript classifier degraded (timeout, Haiku unavailable) or voted differently. Add CombineVerdictOpts.toolOutput flag. When true, a single ML classifier >= BLOCK threshold blocks directly. User-input default path unchanged — still requires 2-of-N to block. Caller: sidebar-agent.ts tool-result scan now passes { toolOutput: true }. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): regression tests for 4 adversarial-review fixes 11 tests pinning the four fixes so future refactors don't silently re-open the bypasses: - Canary rolling-buffer detection (DeltaBuffer + slice tail) - Tool-output single-layer BLOCK (new combineVerdict opt) - escapeHtml quote escaping (both " and ') - snapshot in PAGE_CONTENT_COMMANDS - GSTACK_SECURITY_OFF kill switch gates both load paths - checkTranscript.tool_output plumbing on tool-result scan Most are source-level string contracts (not behavior) because the alternative — real browser/subprocess wiring — would push these into periodic-tier eval cost. The contracts catch the regression I care about: did someone rename the flag or revert the guard. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs: CHANGELOG hardening section + TODOS mark Read/Glob/Grep shipped CHANGELOG v1.4.0.0 gains a "Hardening during ship" subsection covering the 4 adversarial-review fixes landed after the initial bump (canary split, snapshot envelope, tool-output single-layer BLOCK, Haiku tool-output context). Test count updated 243 → 280 to reflect the source-contracts + adversarial-fix regression suites. TODOS: Read/Glob/Grep tool-output scan marked SHIPPED (was P2 open). Cross-references the hardening commits so follow-up readers see the full arc. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs: document sidebar prompt injection defense across user docs README adds a user-facing paragraph on the layered defense with links to ARCHITECTURE. ARCHITECTURE gains a "Prompt injection defense (sidebar agent)" subsection under Security model covering the L1-L6 layers, the Bun-compile import constraint, env knobs, and visibility affordances. BROWSER.md expands the "Untrusted content" note into a concrete description of the classifier stack. docs/skills.md adds a defense sentence to the /open-gstack-browser deep dive. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(security): k-anon suppression in community-pulse attack aggregate Top-N attacked domains + layer distribution previously listed every value with count>=1. With a small gstack community, that leaks single-user attribution: if only one user is getting hit on example.com, example.com appears in the aggregate as "1 attack, 1 domain" — easy to deanonymize when you know who's targeted. Add K_ANON=5 threshold: a domain (or layer) must be reported by at least 5 distinct installations before appearing in the aggregate. Verdict distribution stays unfiltered (block/warn/log_only is low-cardinality + population-wide, no re-id risk). Raw rows already locked to service_role only (002_tighten_rls.sql); this closes the aggregate-channel leak. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): decision file primitives for human-in-the-loop review Adds writeDecision/readDecision/clearDecision around ~/.gstack/security/decisions/tab-<id>.json plus excerptForReview() for safe UI display of tool output. Also extends Verdict with 'user_overrode' so attack-log audit trails distinguish genuine blocks from user-acknowledged continues. Pure primitives, no behavior change on their own. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): POST /security-decision + relay reviewable banner fields Two small server changes, one feature: 1. New POST /security-decision endpoint takes {tabId, decision} JSON and writes the per-tab decision file. Auth-gated like every other sidebar-agent control endpoint. 2. processAgentEvent relays the new reviewable/suspected_text/tabId fields on security_event through to the chat entry so the sidepanel banner can render [Allow] / [Block] buttons and the excerpt. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): wait-for-decision instead of hard-kill on tool-output BLOCK Was: tool-output BLOCK → immediate SIGTERM, session dies, user stranded. A false positive on benign content (e.g. HN comments discussing prompt injection) killed the session and lost the message. Now: tool-output BLOCK → emit security_event with reviewable:true + suspected_text + per-layer scores. Poll ~/.gstack/security/decisions/ for up to 60s. On "allow" — log the override to attempts.jsonl as verdict=user_overrode and let the session continue. On "block" or timeout — kill as before. Canary leaks stay hard-stop (no review path). User-input pre-spawn scans unchanged in this commit. Only tool-output scans gain review. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(ui): reviewable security banner with suspected-text + Allow/Block Banner previously always rendered "Session terminated" — one-way. Now when security_event.reviewable=true: - Title switches to "Review suspected injection" - Subtitle explains the decision ("allow to continue, block to end") - Expandable details auto-open so the user sees context immediately - Suspected text excerpt rendered in a mono pre block, scrollable, capped at 500 chars server-side - Per-layer confidence scores (which layer fired, how confident) - Action row with red [Block session] + neutral [Allow and continue] - Click posts to /security-decision, banner hides, sidebar-agent sees the file and resumes or kills within one poll cycle Existing hard-block banner (terminated session, canary leaks) unchanged. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): review-flow regression tests 16 tests for the file-based handshake: round-trip, clear, permissions, atomic write tmp-file cleanup, excerpt sanitization (truncation, ctrl chars, whitespace collapse), and a simulated poll-loop confirming allow/block/timeout behavior the sidebar-agent relies on. Pins the contract so future refactors can't silently break the allow-path recovery and ship people back into the hard-kill FP pit. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): sidepanel review E2E — Playwright drives Allow/Block 5 tests, ~13s, gate tier. Loads real extension sidepanel in Playwright Chromium with stubbed chrome.runtime + fetch, injects a reviewable security_event, and drives the user path end-to-end: - banner title flips to "Review suspected injection" - suspected text excerpt renders inside the auto-expanded details - Allow + Block buttons are visible - click Allow → POST /security-decision with decision:"allow" - click Block → POST /security-decision with decision:"block" - banner auto-hides after each decision - non-reviewable events keep the hard-stop framing (regression guard) - XSS guard: script-tagged suspected_text doesn't execute Complements security-review-flow.test.ts (unit-level file handshake) and security-review-fullstack.test.ts (full pipeline with real classifier). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): mock-claude scenario for tool-result injection path Adds MOCK_CLAUDE_SCENARIO=tool_result_injection. Emits a Bash tool_use followed by a user-role tool_result whose content is a classic DAN-style prompt-injection string. The warm TestSavantAI classifier trips at 0.9999 on this text, reliably firing the tool-output BLOCK + review flow for the full-stack E2E. Stays alive up to 120s so a test has time to propagate the user's review decision via /security-decision + the on-disk decision file. SIGTERM exits 143 on user-confirmed block. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): full-stack review E2E — real classifier + mock-claude 3 tests, ~12s hot / ~30s cold (first-run model download). Skips gracefully if ~/.gstack/models/testsavant-small/ isn't populated. Spins up real server + real sidebar-agent + PATH-shimmed mock-claude, HOME re-rooted so neither the chat history nor the attempts log leak from the user's live /open-gstack-browser session. Models dir symlinked through to the real warmed cache so the test doesn't re-download 112MB per run. Covers the half that hermetic tests can't: - real classifier (not a stub) fires on real injection text - sidebar-agent emits a reviewable security_event end-to-end - server writes the on-disk decision file - sidebar-agent's poll loop reads the file and acts - attempts.jsonl gets both block + user_overrode with matching payloadHash (dashboard can aggregate) - the raw payload never appears in attempts.jsonl (privacy contract) Caught a real bug while writing: the server loads pre-existing chat history from ~/.gstack/sidebar-sessions/, so re-rooting HOME for only the agent leaked ghost security_events from the live session into the test. Fix: re-root HOME for both processes. The harness is cleaner for future full-stack tests because of it. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(security): unbreak Haiku transcript classifier — wrong model + too-tight timeout Two bugs that made checkTranscript return degraded on every call: 1. --model 'haiku-4-5' returns 404 from the Claude CLI. The accepted shorthand is 'haiku' (resolves to claude-haiku-4-5-20251001 today, stays on the latest Haiku as models roll). Symptom: every call exited non-zero with api_error_status=404. 2. 2000ms timeout is below the floor. Fresh `claude -p` spawn has ~2-3s CLI cold-start + 5-12s inference on ~1KB prompts. With the wrong model gone, every successful call still timed out before it returned. Measured: 0% firing rate. Fix: model alias + 15s timeout. Sanity check against DAN-style injection now returns confidence 0.99 with reasoning ("Tool output contains multiple injection patterns: instruction override, jailbreak attempt (DAN), system prompt exfil request, and malicious curl command to attacker domain") in 8.7s. This was the silent cause of the 15.3% detection rate on BrowseSafe-Bench — the ensemble numbers matched L4-alone because Haiku never actually voted. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(security): always run Haiku on tool outputs (drop the L4 gate) Tool-result scan previously short-circuited when L4 (TestSavantAI) scored below WARN, and further gated Haiku on any layer firing at >= LOG_ONLY. On BrowseSafe-Bench that meant Haiku almost never ran, because TestSavantAI has ~15% recall on browser-agent-specific attacks (social engineering, indirect injection). We were gating our best signal on our weakest. Run all three classifiers (L4 + L4c + Haiku) in parallel. Cost: ~$0.002 + ~8s Haiku wall time per tool result, bounded by the 15s Haiku timeout. Haiku also runs in parallel with the content scans so it's additive only against the stream handler budget, not against the session wall time. User-input pre-spawn path unchanged — shouldRunTranscriptCheck still gates there. The Stack Overflow FP mitigation that original gate was built for still applies to direct user input; tool outputs have different characteristics. Source-contract test updated to pin the new parallel-three shape. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(changelog): measured BrowseSafe-Bench lift from Haiku unbreak Before/after on the 200-case smoke cache: L4-only: 15.3% detection / 11.8% FP Ensemble: 67.3% detection / 44.1% FP 4.4x lift in detection from fixing the model alias + timeout + removing the pre-Haiku gate on tool outputs. FP rate up 3.7x — Haiku is more aggressive than L4 on edge cases. Review banner makes those recoverable; P1 follow-up to tune Haiku WARN threshold from 0.6 to ~0.7-0.85 once real attempts.jsonl data arrives. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(todos): P0 Haiku FP tuning + P1-P3 follow-ups from bench data BrowseSafe-Bench smoke showed 67.3% detection / 44.1% FP post-Haiku- unbreak. Detection is good enough to ship. FP rate is too high for a delightful default even with the review banner softening the blow. Files four tuning items with concrete knobs + targets: - P0 Cut Haiku FP toward 15% via (1) verdict-based counting instead of confidence threshold, (2) tighter classifier prompt, (3) 6-8 few-shot exemplars, (4) bump WARN threshold 0.6 -> 0.75 - P1 Cache review decisions per (domain, payload-hash) so repeat scans don't re-prompt - P2 research: fine-tune BERT-base on BrowseSafe-Bench + Qualifire + xxz224 — expected 15% -> 70% L4 recall - P2 Flip DeBERTa ensemble from opt-in to default - P3 User-feedback flywheel — Allow/Block decisions become training data (guardrails required) Ordered so P0 ships next sprint and can be measured against the same bench corpus. All items depend on v1.4.0.0 landing first. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(security): assert block stops further tool calls, allow lets them through Gap caught by user: the review-flow tests verified the decision path (POST, file write, agent_error emission) but not the actual security property — that Block stops subsequent tool calls and Allow lets them continue. Mock-claude tool_result_injection scenario now emits a second tool_use ~8s after the injected tool_result, targeting post-block-followup. example.com. If block really blocks, that event never reaches the chat feed (SIGTERM killed the subprocess before it emitted). If allow really allows, it does. Allow test asserts the followup tool_use DOES appear → session lives. Block test asserts the followup tool_use does NOT appear after 12s → kill actually stopped further work. Both tests previously proved the control plane (decision file → agent poll → agent_error); they now prove the data plane too. Test timeout bumped 60s → 90s to accommodate the 12s quiet window.
