The detector is open source. The rules it ships were already public in this
repo's git history and in every npm tarball of the JS engine, so a closed
binary bought nothing it could keep; the moat is the service (the catalog,
the labs, the review pipeline), not the check functions. Keeping them behind
a prebuilt archive cost a C-ABI, an exact toolchain pin, a build-time
download, a second release to order ahead of every engine release, and a
serde layer that had to serve two encodings.
Deleted
- crates/core/src/ffi.rs, crates/core/build.rs, crates/core/tests/boundary.rs
and the shim modules under src/checks and src/browser.
- crates/foundation/src/boundary.rs and the postcard dependency.
- DETECTOR_VERSION, scripts/check-detector-release.mjs and its test, the
check:detector-release script, the detector gate and
IMPECCABLE_SKIP_DETECTOR_CHECK in scripts/release.mjs.
- scripts/lib/detector-bundle.mjs and tests/detector-bundle.test.mjs (the
vendoring path for the closed browser bundle).
- scripts/build-browser-detector.js and the build:browser script (a stub
since the JS engine left the tree).
- xtask's detector-archive subcommand and its public-repo lookup.
Came back
- crates/core is now the rule logic itself: every check_* / scan_*, the
browser adapters, the visual-contrast decisions. It re-exports foundation
as before, so no consumer changed. Its vectors dispatcher is the union of
both id tables again, and tests/vectors.rs replays the frozen vectors
straight through it.
- crates/wasm and crates/xtask join the workspace. cargo xtask bundle builds
the in-page bundle from browser-bundle/ plus the wasm core, writes
dist/, refreshes the tracked crates/live/assets/detect-antipatterns-
browser.js, and writes extension/detector/. bun run build:extension runs
it instead of downloading.
- crates/live/assets/detect-antipatterns-browser.js is tracked again; live
mode embeds it and serves it as /detect.js.
- Serde is back to plain derives: no is_human_readable branch in
js::json_number, derived Serialize for Rgba and BrowserFinding with their
skip_serializing_if attributes.
- profile.release has lto = "fat" again; rust-toolchain.toml is plain
stable plus the wasm32 target. The rust, rust-windows and oracle CI jobs
lose continue-on-error and can be required.
Verified
- cargo build --workspace --all-targets: clean, no warnings.
- cargo test --workspace: 346 pass, 0 fail (the 8 boundary tests are gone
with the boundary).
- cargo build -p impeccable-wasm --target wasm32-unknown-unknown --release: ok.
- cargo xtask bundle && cargo xtask bundle --check: reproducible; the
regenerated bundle is committed (it differs from the archived one, which
was built with a pinned rustc and lto = false).
- cargo build --release -p impeccable: no linker warnings, 12.5 MB (the
same source at lto = false is 13.1 MB).
- oracle: 795 pass, 0 fail, 0 accepted deltas, 0 missing goldens.
- bun run build, bun run build:extension, web-ext lint (0 errors,
8 warnings), bun run test: 363 + 80 + 1 + 1 + 133 + 180 + 4 pass, 0 fail.
- impeccable detect --no-config --json tests/fixtures/antipatterns: 128.7 ms
median of 5.

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.
