Garry TanandClaude Fable 5.1	b2e67d0097	fix(design-detect): an engine is a file named impeccable outside the project; DOM dumps scan without inline ignores ... Second review cycle, security + checklist: - IMPECCABLE_BIN=/bin/sh (or node) was READY, and `detect` with cwd=repoRoot made the interpreter run the repository's own `detect` file. Every engine candidate (env override, PATH entry, cache, sibling) is now judged by the realpath of the FILE and must be named impeccable[.exe]; PATH and cache candidates that resolve into the repository are skipped like the others. "Inside the project" means the repository, or cwd when cwd is a project directory: HOME and its ancestors are exempt, so a URL-mode review launched from HOME still finds the HOME-rooted installs. - A base for --changed that starts with `-` was spliced into git argv (`--output=<file>` made git write a file and report no changes); an option- like or missing base is DETECT_REFUSED (not a ref name), exit 1, and the parser no longer defaults a missing value to main. - DOM dumps are the audited page's bytes, so an in-file `impeccable-disable` comment there is page-controlled: batches under the designs root run with --no-inline-ignores, repository batches keep the project's own ignores. - neutralizeSentinels covers the shapes it missed (bare sentinels such as DETECT_TOP total= and IMPECCABLE_DISABLED, the DETECT_EXIT_CODE= echo, the `[rule-id] impact=` group header) in one precompiled alternation instead of 37 replaceAll passes per field; only kept findings are normalized, and the summary's total stays the engine's count. - The minimal engine environment compares keys case-insensitively on Windows (process.env enumerates Path, SystemRoot there) and passes PATHEXT, COMSPEC, HOMEDRIVE, HOMEPATH, PROGRAMDATA. - Bare 64s move into DETECT_LIMITS; the unused SentinelName type is gone; the header states the directory-target contract (the engine's own walk). Tests: an interpreter as IMPECCABLE_BIN never runs the repo's detect file; a PATH symlink into the repository is never READY; option-like and empty bases are refused with no file written; the designs-root batch carries --no-inline-ignores and the repo batch does not; the identity label is deterministic per binary; the bare-sentinel and header shapes are neutralized; the installed fake engine works without IMPECCABLE_FAKE_OUTPUT (the helper copies the sample beside it); two tests clean up in finally.

Garry TanandClaude Fable 5.1	60758c5ddf	fix(design-detect): never execute a repository-controlled engine; allow-list --changed targets; sanitize engine text ... Pre-landing review findings (security + checklist), all reproduced before the fix: - A checked-out branch could commit `.claude/skills/impeccable/scripts/bin/<os>-<arch>/impeccable` and the probe would report READY and `scan` would run it, with the agent's full environment. Launchers and sibling engines under the repo or cwd now count as "skill present" only (IMPECCABLE_NOT_CACHED: repository-local install, and the hint never names a repository-local launcher to run); only HOME-rooted installs, IMPECCABLE_BIN, the cache, and PATH entries outside the repo qualify, all by realpath. The engine now sees a minimal environment (PATH, HOME, TMPDIR, locale, IMPECCABLE_*), never the agent's tokens. - `scan --changed <base>` pushed git-derived paths without the allow-list, so a committed symlink with a frontend extension handed a file outside the repo to the engine. Derived targets now go through the same allow-list as explicit ones and symlinks named by git are refused outright. - A repo-controlled `scripts/VERSION` with embedded newlines forged probe lines; the version is trusted only when it is semver, and every printed version is sanitized. Engine text containing the untrusted-content fence or a `SENTINEL:` prefix is neutralized with a zero-width space (neutralizeSentinels in the contract), so page text cannot close the envelope or forge a probe line. - A failing `git diff <base>...HEAD` (unknown or unfetched base) was swallowed and read as "no frontend changes"; it is now DETECT_REFUSED with exit 1. - The scan allow-list root follows `${GSTACK_HOME:-$HOME/.gstack}` like the templates and gstack-slug (config.yaml keeps gstack-config's STATE_ROOT precedence); a quoted or commented design_detector value reads correctly. Smaller: raw engine chunks are kept only in --format raw; diagnostics are capped (200 kept, 20 echoed); the engine identity hash reads size + 4 MB, not the whole binary; PROBE_STEP and ENGINE_STDERR are contract sentinels; the --verbose gate covers every probe step; analytics use one sentinel vocabulary; bare limits live in DETECT_LIMITS. The fake engine's knobs are IMPECCABLE_FAKE_* (so they pass the minimal env) and a shared test helper installs it. New tests cover each item above plus clean runs, `{}` parse errors, missing paths, and the 50 MB stdout cap. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>	2026-09-08 17:31:30 +00:00
Garry TanandClaude Fable 5.1	3867dae355	feat(bin): gstack-design-detect wrapper + design_detector config key ... bin/gstack-design-detect.ts finds and runs an impeccable engine the user installed; it never installs, downloads, or executes anything that could download. `probe` reads only: config (design_detector off → DISABLED), IMPECCABLE_BIN (absolute, realpath outside the repo and cwd), a PATH walk (absolute entries outside the repo; a #! shim counts as launcher-present, never READY), the ~/.impeccable/bin/<newest semver>/ cache, and the engine installed beside a skill launcher (scripts/bin/<os>-<arch>/impeccable, the layout a real install produced). It reports IMPECCABLE_SKILL, host-aware IMPECCABLE_HOOK (+ HOOK_OTHER), the ignore lists from .impeccable/config*.json, IMPECCABLE_ENGINE_UNTESTED for versions outside the fixture set, and a hint only when a launcher exists without its engine. `scan` re-probes, refuses URLs and anything outside the repo root or the design-report allow-list (realpath, so symlinks cannot escape), derives `--changed <base>` targets NUL-safely through git and lib/frontend-scope.ts, batches 100 absolute paths per engine call with stdin ignored, a SIGKILL timeout, a 50 MB stdout cap, and sanitized length-capped fields, then prints one normalized JSON document (--format gstack) or the engine's bytes (--format raw); DETECT_TOP (fenced as untrusted content), DETECT_SUMMARY, and DETECT_EXIT go to stderr; exit code passes through with 1 over 2 over 0; exit 3 is a gstack bug. `rules` prints the mapped set. Every run appends a content-free line to the local analytics file. lib/design-detect-contract.ts owns every sentinel string, the limits, and the normalized-finding shape (pure module); test/design-detect-contract.test.ts asserts every sentinel-shaped token the agent can read exists there. lib/frontend-scope.ts mirrors gstack-diff-scope's frontend arm, pinned by a parity test that runs the bash script. bin/gstack-config gains design_detector (auto | off, default auto, invalid values rejected with the file unchanged). test/fixtures/fake-impeccable.ts is the env-driven engine stand-in; test/gstack-design-detect.test.ts covers READY/NOT_CACHED/ NOT_AVAILABLE/DISABLED, env trust (.env never loaded, in-repo IMPECCABLE_BIN ignored), newest-semver cache, hook and ignore detection, refusals, exit passthrough, raw byte-identity, normalization, the display cap, timeout, parse errors, diagnostics, --changed, and analytics. The egress scanner test records the wrapper as a documented non-sink. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>	2026-09-08 16:01:18 +00:00
