From e2ff625b6371c3f05a31e576fe9e7d063bcb112b Mon Sep 17 00:00:00 2001 From: Paul Bakaus Date: Fri, 4 Sep 2026 10:42:45 -0700 Subject: [PATCH] The Rust engine: one binary replaces every script and the JS detector, fully open (#714) * Add oracle harness: verb goldens and function-level vectors Records stdout/stderr/exit/files for every impeccable verb over a fixed corpus and replays them against an alternate implementation. Adds a loader hook that captures per-function call vectors from the pure engine modules. Prepared with AI assistance (Claude Code). * Oracle: hook, hook-before-edit, hook-admin cases and goldens Prepared with AI assistance (Claude Code). * Add docs/CLI-CONTRACT.md: observable behavior of every impeccable verb Prepared with AI assistance (Claude Code). * Oracle: context/doctor/pin/surface-brief/critique/palette/embed/signals/csp/seed/genimg/question cases and goldens Prepared with AI assistance (Claude Code). * Oracle: live-mode cases and goldens (roots, inject, wrap, insert, accept, session, manual edits, daemon) Prepared with AI assistance (Claude Code). * Oracle: mask the binary path before HOME; export launcher env to the binary Prepared with AI assistance (Claude Code). * detect: set process.exitCode instead of exiting after the final write process.exit() right after a large piped stdout write truncated JSON output at the pipe buffer boundary; found by the oracle harness. Re-record the six directory-scan goldens that had captured the truncation. Prepared with AI assistance (Claude Code). * Oracle: normalize the hook-admin command in both runtimes' forms and audit chars Prepared with AI assistance (Claude Code). * Skill text: invoke the impeccable launcher instead of node scripts Every `node {{scripts_path}}/.mjs` becomes `{{scripts_path}}/impeccable ` (context-signals -> signals, hook-admin -> hooks). Setup step 1 drops Node, points Windows shells without sh at impeccable.cmd, and says the launcher runs a self-contained binary. allowed-tools follows. Prepared with AI assistance (Claude Code). * Scripts dir: replace the Node scripts with the impeccable launcher 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/-/, and gitignores that bin dir. Prepared with AI assistance (Claude Code). * Build: ship the launcher instead of bundling the JS engine 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 `/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// 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). * CLI: turn the impeccable npm package into a platform-binary shim 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-- optional dependency (templates under cli/platform-packages/, published by the engine release), the ~/.impeccable/bin// 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). * Tests: gate behavior on the oracle and the engine binary 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//, 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). * Docs: describe the launcher, the engine pin, and the oracle gate 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). * Tests: tighten the hook command guard assertion Prepared with AI assistance (Claude Code). * Oracle: re-golden 46 cases for the engine's own command names; record them in DELTAS.md Prepared with AI assistance (Claude Code). * Build: ship launcher-only release zips by default 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). * Tests: drive the live-e2e orchestrator through the engine binary The session, fake-agent loop, steer test, and manual-edit probe spawn (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). Prepared with AI assistance (Claude Code). * Tests: run new-work-e2e through the engine's serve-question and generate-image verbs Prepared with AI assistance (Claude Code). * Tests: point the skill-behavior harness at the launcher and engine binary 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). * Tests: note what plugin-e2e validates before and after the generated-output sync Prepared with AI assistance (Claude Code). * Oracle: record the engine's 'wasm-unsafe-eval' CSP meta patch as a reviewed delta Prepared with AI assistance (Claude Code). * Rebase reconciliation: fold main's post-freeze work into the swapped tree 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. AI-assisted change: implemented with Claude Code. Co-Authored-By: Claude Claude-Session: https://claude.ai/code/session_01WaJv2c4oN8wS7Ttq4XRqyx * Launcher: engine-probe PATH validation, working .cmd download path; CI: drop stale path, add oracle job 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). * Oracle: restore detector goldens to post-fix behavior after the engine ports 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. Prepared with AI assistance (Claude Code). Co-Authored-By: Claude Fable 5 Claude-Session: https://claude.ai/code/session_01WaJv2c4oN8wS7Ttq4XRqyx * Oracle: pin the Aug 17-31 verb fixes ported to the Rust engine 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). Prepared with AI assistance (Claude Code). * Oracle: drop a duplicated DELTAS section The verb-fix section landed twice when two porting sessions staged the same file; keep one copy. Prepared with AI assistance (Claude Code). * Oracle: pin the hooks ignore-value inert-entry refusal 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). * Launcher: fail closed on a missing download checksum (engine triage C1) 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. Prepared with AI assistance (Claude Code). Co-Authored-By: Claude Code Claude-Session: https://claude.ai/code/session_01WaJv2c4oN8wS7Ttq4XRqyx * Enforce engine-before-skill release order (triage D4) 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-- 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. Prepared with AI assistance (Claude Code). * Oracle: re-record the Sep-1 verb fixes ported to the Rust engine 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. Co-Authored-By: Claude Opus 4.8 Claude-Session: https://claude.ai/code/session_01WaJv2c4oN8wS7Ttq4XRqyx * Tests: fix pre-existing release-guard staging on the swap branch 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. Co-Authored-By: Claude Opus 4.8 Claude-Session: https://claude.ai/code/session_01WaJv2c4oN8wS7Ttq4XRqyx * oracle: pin E8 stale-hook-manifest detector fallback (context) 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. Co-Authored-By: Claude Opus 4.8 Claude-Session: https://claude.ai/code/session_01WaJv2c4oN8wS7Ttq4XRqyx * Tests: stop two harness hangs from wedging a whole run 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. Prepared with AI assistance (Claude Code). * launcher: export skill-dir env before the IMPECCABLE_BIN exec (sync engine fix) Prepared with AI assistance (Claude Code). * Node-free swap: comp-fidelity verbs move to the engine 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 ` instead of `node + * Re-scan: window.impeccableScan() + */ +(function () { +if (typeof window === 'undefined') return; diff --git a/browser-bundle/10-probe.js b/browser-bundle/10-probe.js new file mode 100644 index 000000000..890bac3a4 --- /dev/null +++ b/browser-bundle/10-probe.js @@ -0,0 +1,202 @@ +// --- browser-bundle/10-probe.js --- +// The DOM probe the WASM rule core calls back into.
