The parser stopped reading a paths: list at its first comment line, so every glob after it was dropped and a pull request touching only those paths was answered false: its workflow's tests skipped, silently. wai-http, which has used this gate for weeks, was read as 10 of its 41 paths. The list now continues past comments and blank lines, and a trailing comment is not part of a glob; every workflow's list is read exactly as its YAML states it. The self-test gains the case, and fails it with the old parser. Co-Authored-By: Claude Opus 5.5 <[email protected]>

The forge matches a workflow's paths: against the push, not the pull request, so merging main into a branch fired every path-filtered workflow whatever the pull request changed. wai-pack and wai-web-reach already guarded against this with scripts/pr-touches-paths.py; wai-conformance, wai-formal-verification, wai-vector, wai-ops, wai-quantum-webgpu, conformance, wai-energy-receipts, wai-byte-equality, wai-jpegai-e2e, wai-neural-e2e, wai-sota-vectors, wai-neural-gates and wai-web-wasm now do too: a light job on linux-arm64 answers whether the pull request's diff touches the workflow's paths, and every other job waits on it. A push to main, a schedule, or anything the script cannot determine answers true. Co-Authored-By: Claude Opus 5.5 <[email protected]>
