The engine binaries move from the impeccable-dist channel to this repo's own
GitHub Releases (tag engine-v<ENGINE_VERSION>), and the closed detector the
engine links arrives as detector-v<DETECTOR_VERSION> releases on the same
repo. This commit wires the public side for that; the crates themselves land
in the next commit.
- Launcher (sh + cmd), npm shim, fetch-engine and check-engine-release now
download from github.com/pbakaus/impeccable/releases/download/engine-v<X>/.
- release.mjs gains `engine`: verifies ENGINE_VERSION against the platform
package pins and the detector release, tags, pushes; release-engine.yml
builds the five targets and publishes. check-detector-release.mjs is the
matching release-order guard (with tests).
- Root Cargo.toml (workspace, lto = false with the reason), rust-toolchain.toml
(exact pin), DETECTOR_VERSION, /target ignored.
- CI: rust + rust-windows jobs and an oracle job that replays the goldens
against a source build, warn-only until the first detector release exists;
ci-test-plan exposes a `rust` output.
- docs/ENGINE.md (the crate map and the closed-detector mechanism) and the
CLAUDE.md engine, release-order and rules sections.

The four comp-fidelity scripts (comp-spec, comp-diff, font-match, build-phase)
and their six libs are ported into the impeccable-engine binary. This removes
the last Node .mjs from the skill: `git ls-files skill/scripts | grep '\.mjs$'`
now returns nothing.
- reference/new-work.md, reference/visualize.md, and the asset-producer /
finish-reviewer agents now invoke `{{scripts_path}}/impeccable <verb>` instead
of `node <script>.mjs`.
- Deleted the ten ported .mjs and the four JS unit tests that imported them
(their behavior is now covered by the engine's Rust tests and the oracle);
removed those files from scripts/test-suites.mjs.
- Added oracle cases (comp-*, font-match-*, build-phase-*) over a comp-basic
workspace, recorded from the engine binary; the deterministic outputs are
byte-identical to the JS the scripts left behind.
- docs/CLI-CONTRACT.md documents the four verbs, the CDP font rendering, and
the runtime-resolved (never-committed) font-index catalog.
The font-index catalog JSON stays shipped in the skill (data/font-index.json);
the engine resolves it at run time and never vendors it.

Two suites could hang forever and never print a tally, because the one
mechanism that could interrupt the wedged work was missing on both paths.
Hang 1 (bun run test / build-phase.test.mjs): the test's run() helper
spawned every child with spawnSync and no timeout. spawnSync blocks the
test worker's thread, so node's --test-timeout (an event-loop timer)
cannot interrupt a child that wedges (a fork/exec blocked on OS resources
under concurrency, a gate's comp-diff grandchild, or a stray browser
launch). Bound every child with spawnSync timeout + killSignal SIGKILL so
a wedge becomes a fast, named failure the next test survives.
Hang 2 (bun run test:skill-behavior): runTurn called generateText with no
client-side deadline, so a stalled provider stream kept the fetch (and the
whole node process) alive past the per-test timeout, producing no tally.
Attach a real AbortSignal (default 840s, under the 900s per-test cap):
on expiry the fetch aborts, the turn throws, and the scenario
fails-and-continues. The unref'd timer is cleared on completion.
Runner backstops: run-tests.mjs now spawns each command as a detached
process-group leader and enforces a per-suite wall-clock cap that SIGKILLs
the entire group (workers, grandchildren, browsers) on expiry, with
SIGINT/SIGTERM forwarded so Ctrl-C still reaps the tree. The core node
batch gets a finite --test-timeout (180s); skill-behavior gets a 60min
group cap. Env overrides: IMPECCABLE_TEST_WALL_CLOCK_MS,
IMPECCABLE_SKILL_BEHAVIOR_TURN_TIMEOUT_MS,
IMPECCABLE_BUILD_PHASE_RUN_TIMEOUT_MS.
Proof: bun run test green twice (~60s); scoped claude-sonnet-5
skill-behavior sweep terminates with a tally (20 tests, ~32min) where the
840s abort caught a wedged redesign turn and the sweep continued instead
of hanging.

Cover the v3-to-launcher upgrade fix (triage E8) recorded from the engine
binary and hand-reviewed:
- context-stale-hook-manifest: a .claude/settings.local.json naming the retired
`node .../hook.mjs` script under the claude-code provider emits
MANUAL_DETECTOR_REQUIRED, because the stale marker no longer counts as an
active hook (its script is gone after the update).
- context-launcher-hook-active: the same manifest in the launcher form still
suppresses MANUAL_DETECTOR_REQUIRED, confirming the launcher marker is
recognized as active.
The only difference between the two goldens is the MANUAL_DETECTOR_REQUIRED
block. No existing golden moved: every other context case runs under the source
provider, whose hook-manifest list is empty, so none of them scan a manifest.
Also null IMPECCABLE_PROVIDER_ID in the case BASE_ENV so a recording machine's
value cannot leak. DELTAS.md records the intentional divergence from JS parity.

release.test.mjs was already red on the swap branch: release.mjs imports
check-engine-release.mjs and fetch-engine.mjs (the D4 engine release-order
guard), which the temp work tree never staged, so every dry run failed to
resolve the module instead of exercising the guard. Stage both modules and set
IMPECCABLE_SKIP_ENGINE_CHECK=1 so the guard does not probe the network; this
suite predates the guard and only covers the version/changelog/artifact checks.

Five fixes landed on main in JS between the swap branch and its rebase and were
ported to the engine; the goldens they touch are re-recorded from the fixed
binary, each engine output first diffed byte-for-byte against the upstream JS on
the same inputs. DELTAS.md documents every case with its upstream hash.
- critique-* (usage/unknown/latest-existing/write-then-read/write-monorepo-child):
the #660 critique close path (identity + fingerprint freshness, ~NNNN
collision suffix, closed flag, close verb, latest --json). Upstream 5211bdf4.
- detect-* (new overused-font fixture cases, dir/scope/no-advisory sweeps):
the #678 overused-font primary-face change (a system stack keeps its system
face, so a Roboto fallback no longer flags). Upstream 2cfd6076.

The launcher, npm shim, and `impeccable install` all resolve the engine
binary for the pinned ENGINE_VERSION, so a skill/CLI release or a rust-swap
merge published ahead of the engine release + platform packages dead-ends
every install path. Add a mechanical guard:
- scripts/check-engine-release.mjs: verifies all five dist binaries +
.sha256 and the five @impeccable/cli-<os>-<arch> npm platform packages
exist for the pinned ENGINE_VERSION; names missing assets, exits non-zero.
Honors IMPECCABLE_DOWNLOAD_BASE.
- release.mjs: hard-fails release:skill and release:cli when assets are
missing; extension is exempt (vendored WASM detector, no engine exec).
- CI engine-release-ready job: runs the check, continue-on-error with a
loud ::warning until the first engine release exists (flip to false then).
- CLAUDE.md Releases: documents the enforced ordering.

Byte-identical sync of the engine repo's launchers: a freshly downloaded
engine binary now runs only after verifying against its .sha256 sidecar.
A sidecar that cannot be fetched, or a machine with no sha256 tool,
refuses the download instead of exec'ing an unverified binary; the
wget-only path fetches the sidecar too. Binaries already on PATH or in
the cache that pass engine-probe are unaffected.

Three hadmin-ignore-value-inert-* cases record the engine's port of
be87f5eb (#662) to hooks ignore-value: an exact value for a rule whose
findings can never extract one is refused with the wildcard-plus-file
route (and no config write), while the wildcard scoped form for the same
rule is accepted. Goldens recorded from the engine binary and verified
byte-for-byte against the ea360025 hook-admin.mjs on the same sequences.
No existing golden changes, so no DELTAS entry is owed.
Prepared with AI assistance (Claude Code).
New cases: hook-session-grok-edit-then-stop (Grok Build camelCase envelope,
end_turn/shutdown/stopHookActive Stop handling, 35ae0733 + bfe634e2 +
3c442af7, #646), hook-session-codex-stop-decision (Codex Stop emits
decision/block, c9e7cd8a, #603), and doctor-order-boot-and-deep (boot and
deep findings keep their established artifact order, 80997663).
Re-recorded goldens whose old bytes froze pre-fix behavior, with a
DELTAS.md entry naming each upstream hash: the Stop finding-cache sync
(3c442af7), the Edit|Write manifests without the retired MultiEdit matcher
(7d5c60d2), and the failWithRollback field order (1f2c3f9d).

The Aug 17-31 detector fixes (oklch parsing, color-mix nested hex, 1D grid
pass, comment stripping, root-relative linked stylesheets, URL userinfo
redaction, inert ignore-value refusal) and the comp-fidelity rules
organic-clip-path / buried-raster are ported to the engine. Re-records the
gap-pinning detect goldens from the fixed binary (glow.html included: its
.photo-opaque-grad column now carries the buried-raster finding it was
written for), replays the frozen checkHtmlPatterns call vectors through the
last JS engine state in history (db1462b9^; args untouched, 14 of 101
results moved), and rewrites the DELTAS gap section into the landed-ports
note. Each re-recorded json fixture golden byte-matches that JS state's
output; oracle: 770 pass, 0 fail.

Byte-identical copies of the engine repo's launchers (engine main
af7572c): the retired 3.x npm CLI on PATH or in ~/.impeccable/bin is
rejected by the engine-probe handshake instead of hijacking every verb;
impeccable.cmd's download path is rewritten as straight-line goto flow
(the parenthesized blocks expanded %url%/%cached% at parse time, making
it dead code) with certutil sha256 verification and a windows-arm64 ->
x64 asset fallback; the final error points at the release download
instead of npm i -g (npm still serves the 3.x CLI).
ci.yml: the generated-output check no longer diffs the deleted
cli/engine/detect-antipatterns-browser.js, and a new oracle job fetches
the pinned engine (bun run fetch:engine) and replays tests/oracle/
against it. The job is continue-on-error with a loud warning until the
first engine release exists; flipping it to required is a release-time
toggle, documented in the workflow.
Verified here: sh -n on both launcher copies, bun run build green, full
oracle replay against the rebuilt engine binary green (770 pass, 0
fail), and a launcher behavior test proving a fake 3.x CLI on PATH is
skipped while the download + checksum chain completes against a local
file server.
Prepared with AI assistance (Claude Code).
The rebase onto origin/main brought changes whose JS engine halves left the
tree with the swap. This commit reconciles what survives:
- Suite map: register main's comp-fidelity unit tests (build-phase,
comp-diff, font-match, hero-checks) in the core suite and
live-browser-ignores in the live suite.
- Payload guard: the skill scripts payload now allowlists the comp-fidelity
build pipeline (comp-spec/comp-diff/build-phase/font-match and their libs),
the one Node toolchain that has not moved into the engine.
- Drop skill/scripts/live/project-ignores.mjs, lib/live-path-globs.mjs, and
their test: they import hook-lib/live-inject/impeccable-paths, which the
swap deleted, and their consumer (the JS live server) is the engine now.
- skill text: the comp pipeline's calls to engine verbs (generate-image,
embed-prompt) use the launcher spelling.
- Oracle: re-record 17 detect goldens over the fixture set main changed
(oklch #592, color-mix #578, 1D grid #615, the two comp-fidelity rules)
and record the gap in DELTAS.md; those JS rule changes are not yet ported
to the engine, and the goldens pin its current behavior.
bun run test (oracle included) and bun run build are green on this tree.

The bash tool exports IMPECCABLE_BIN so the staged skill's launcher runs
without a download; scenarios assert on 'impeccable context' instead of
context.mjs and skip without a binary.
Prepared with AI assistance (Claude Code).
The session, fake-agent loop, steer test, and manual-edit probe spawn
<binary> <verb> (live-server, live, live-inject, live-wrap, live-insert,
live-accept, live-poll, live-complete) resolved by tests/lib/engine-bin.mjs
instead of node skill/scripts/live-*.mjs; the completion typing the agent
imported from the deleted live/completion.mjs is a small local helper. The
live-e2e helper unit tests move back into the default live suite (the steer
loop skips without a binary).

IMPECCABLE_BUNDLE_ENGINE=1 opts in to staging the engine binaries into the
dist skill copies. Bundling every target into every provider copy put
dist/universal.zip near 340 MB, past the 25 MB Cloudflare Pages file cap
that impeccable install downloads through.
Prepared with AI assistance (Claude Code).
CLAUDE.md gains an Engine binary section (launcher lookup order, ENGINE_VERSION,
untracked binaries, how tests get one, the oracle as behavior gate, what stays
JavaScript) and drops the Node-script and JS-detector descriptions; the CLI
and detection-rule sections point at the shim and the engine repo. README.md
states the skill needs no runtime and lists the launcher-based hook commands;
AGENTS.md follows. CLI-CONTRACT.md's intro notes the scripts it quotes are
the recorded source, not the tree.
Prepared with AI assistance (Claude Code).
Unit tests of the deleted Node scripts and the JS detector are removed;
their behavior is pinned by tests/oracle goldens (frozen JS behavior plus
reviewed deltas) and the engine's own tests. tests/oracle.test.mjs replays
the corpus against the binary (IMPECCABLE_BIN or skill/scripts/bin/<target>/,
via tests/lib/engine-bin.mjs) and skips cleanly without one; the framework
fixture sweep drives live-inject, live-wrap, and detect-csp through the
binary the same way. record.mjs learns --bin. The function-level vectors
under tests/oracle/vectors/calls are committed as the frozen snapshot they
can no longer be regenerated from. Suites: core trimmed to build and
transformer tests, oracle added to the default run, detector/live reduced to
packaging and reference checks, the live-e2e helper tests move to the opt-in
live-e2e lane pending its retarget, cli-remote-e2e is an empty placeholder.
Prepared with AI assistance (Claude Code).
cli/engine, cli/lib, and cli/bin/commands are gone; their behavior lives in
the engine binary. cli/bin/cli.js now resolves the binary from IMPECCABLE_BIN,
the @impeccable/cli-<os>-<arch> optional dependency (templates under
cli/platform-packages/, published by the engine release), the
~/.impeccable/bin/<version>/ cache, or a checksum-verified download, and
execs it. package.json drops the engine dependencies and the library
exports; puppeteer moves to devDependencies for the icon scripts.
README.npm.md describes the shim.
Prepared with AI assistance (Claude Code).
readSourceFiles no longer copies cli/engine into the skill; the scripts
payload is the launcher (executable bit preserved through dist, plugin/, and
universal.zip), impeccable.cmd, VERSION (synced from ENGINE_VERSION on every
build), the page JS, and command-metadata.json. Hook manifests call
`<scripts>/impeccable hook` behind an existence guard (Codex adds a
commandWindows sibling calling impeccable.cmd; Cursor runs hook-before-edit;
GitHub keeps the git rev-parse form; Grok mirrors Claude); the Node probe and
systemMessage notice are gone. build:release fetches the pinned engine for
every target (lenient) and stages bin/<os-arch>/ into the dist skill copies
after root harness dirs and plugin/ were synced, so git-delivered trees stay
launcher-only. The detection-rule count check reads the vendored
extension/detector/antipatterns.json and is skipped when absent.
build:browser is a stub; the codex prefix rewrite leaves
`{{scripts_path}}/impeccable` alone.
Prepared with AI assistance (Claude Code).
skill/scripts keeps command-metadata.json and the page JS; every .mjs entry
point, lib/, and live/ are gone (the binary owns those verbs). Adds the POSIX
launcher, impeccable.cmd, VERSION (copied from the new root ENGINE_VERSION),
scripts/fetch-engine.mjs (bun run fetch:engine) to pull the pinned binary
into skill/scripts/bin/<os>-<arch>/, and gitignores that bin dir.

Every `node {{scripts_path}}/<name>.mjs` becomes `{{scripts_path}}/impeccable <verb>`
