…-usage gate Refs #4111. That issue auto-closed on #4114's merge with two of its three items undone. #4114 handled item 1 (five unreferenced favicons). This does items 2 and 3. Item 2 (the logo). Verified byte-identity with git hash-object/sha256: the logo exists at exactly three tracked paths (not the issue's claimed four), each ~1.39 MB — apps/viewer/public/logo.png, apps/landing/assets/logo.png, docs/assets/logo.png. All three are genuinely necessary: apps/viewer is the SPA at ifclite.com; apps/landing is a separate static site (its own vercel.json, no build step) whose build-docs.sh also assembles the mkdocs site under it for the ifclite.dev Vercel deploy; docs/ is additionally built and deployed standalone to GitHub Pages by .github/workflows/docs.yml, which requires docs/assets/logo.png to exist in the mkdocs source tree regardless of the landing build. No safe dedup exists without adding a symlink or a build-script copy step for marginal benefit, so all three are kept — but all three are losslessly recompressed (Pillow optimize=True, verified pixel-identical) from 1,457,769 to 1,320,603 bytes each, saving ~411 KB across the three copies for zero visible change. Also deleted four more unreferenced favicon originals under apps/viewer/public (favicon-{16x16,32x32,48x48,64x64}.png, ~6.4 KB total) — the same leftover pattern as #4114's five, flagged in the issue thread but left for this PR. apps/viewer/public: 4,456,048 -> 4,312,468 bytes (26 -> 22 tracked files). Item 3 (the gate). scripts/check-asset-usage.mjs fails when apps/viewer/public gains a file no tracked text file anywhere in the repo references (a substring search over basename / scan-relative path / root-absolute path, deliberately permissive so it errs toward a missed dead file rather than a live one flagged dead). Its ALLOWLIST covers convention-fetched paths a browser or crawler requests by fixed name with no in-repo link (favicon.ico, apple-touch-icon.png, robots.txt, sitemap.xml). Detection logic lives in scripts/lib/asset-usage.mjs, tested against synthetic asset/corpus lists in scripts/check-asset-usage.test.mjs (8 cases) so a future change to the repo's real assets can't make the tests vacuously pass. Wired into .github/workflows/test.yml's node-tests job (both the gate and its regression test), named check-asset-usage.mjs so check-test-wiring.mjs's GATE_NAME_RE actually sees it — confirmed: check-test-wiring reports 50 gate scripts / 98 scripts/ test files (up from 49/97) with this one counted as wired, not listed among the @unwired-by-design exceptions. Proved both directions locally: adding a git-added, unreferenced file under apps/viewer/public makes the gate fail naming it; removing it makes the gate pass again. Not done: nothing — items 2 and 3 are both addressed here, item 2 by keeping all three copies (justified above) rather than by deleting any. #4111 is closed (auto-closed by #4114's merge), so this can't close it. Either a maintainer reopens it, or applies `unqueued` themselves — a self-applied label is stripped as SELF_APPLIED_LABEL, so this PR carries neither.

Context for review — this finishes the two items #4111 still had outstanding when it auto-closed on #4114's merge (the Two things worth highlighting for the reviewer: The issue's premise was wrong, and the fix is not a dedup. #4111 said the logo was committed under four paths; there are three, all byte-identical ( Collapsing those to one copy would couple two doc pipelines that are currently independent. So all three are kept and losslessly recompressed instead — pixel identity verified before overwriting, ~411 KB saved, nothing visibly changed. A broken logo in production would cost far more than the bytes. The gate is the part that stops recurrence. Proven both directions against a real tracked file, and genuinely wired:

The gate's substring scan skipped .mts/.cts, so tools/demo-kit/derive- variants.mts — which builds apps/viewer/public/samples/* paths — was invisible to it. Nothing misfires today only because each sample name also appears verbatim in apps/viewer/src/lib/tours/demo-kit.ts and AGENTS.md, both already-scanned extensions; removing that redundant mention while the .mts generator remained the only reference would have made the gate call a live asset dead and block CI. Moved TEXT_EXTENSIONS into scripts/lib/asset-usage.mjs so it's importable from the test file without spawning the CLI. Did not add .sh/.py/.rs: grepped every tracked file with those extensions against every current apps/viewer/public asset's basename and found no consumer, so there's nothing to justify the extra scan cost for them yet. Verified: constructed a case where an asset is referenced only from a .mts file — 8/8-passing gate flagged it dead (RED), passes after the fix (GREEN). Reverting the extension list fails the new regression test (mutation check). Gate still passes for all 22 current files and still fails for a genuinely unreferenced one. Runtime unaffected (dominated by node/git-subprocess startup; two extra small files read). Refs #4111.

Exclude each candidate asset from its own corpus.
corpusFiles includes every tracked text file, including the candidate under apps/viewer/public. An unreferenced text asset such as foo.txt that contains foo.txt will therefore mark itself as referenced and make the gate pass. Keep references from other public assets, but exclude only the current asset when evaluating it.

…bsolute-form test check-ci-path-coverage.mjs flagged scripts/check-asset-usage.test.mjs for reading vercel.json with no filter that can trigger the job. The literal was a fixture label in a synthetic corpus entry, not a real read: the gate's derivation only sees that it names a path that exists in the tree. findUnreferencedAssets matches on the corpus entry's `content`, never its `path`, so the label was free to change. Renamed it to a name with no real-file collision instead of adding an allowlist exemption, since that keeps the coverage gate able to catch an actual uncovered path in this same file untouched.

…ment The comment claimed .sh/.py/.rs were excluded because none of them reference a path under apps/viewer/public. That's false for .rs: two Rust tests (rust/processing/tests/instancing_dont_bake.rs and rust/geometry/tests/clash_intersection_real_model.rs) reference hello-wall.ifc and infra-bridge.ifc under that directory. The gate still passes today only because both assets are also referenced from McpPlayground.tsx, an already-covered extension. Kept the exclusion rather than adding .rs to TEXT_EXTENSIONS: a basename-only substring search over the repo's ~800 Rust files matches generic test-fixture names (e.g. "manifest.json" in unrelated test corpora) that have nothing to do with apps/viewer/public, so it would add scan noise without closing the actual gap — the two real .rs references are already covered elsewhere. Added a short comment at the McpPlayground.tsx reference noting the gate depends on it.
