ci(dogfood): make the invisible-character gate fail closed - #97
Conversation
PR #90 fixed the pattern so it can match at all, but the step still never failed: findings were emitted as ::warning and grep errors were sent to /dev/null (Codacy MEDIUM on #90, valid). A gate that only warns is not a gate. - planted positive at the top of the step: if the pattern does not fire on a literal NBSP the step exits 1 (the class of fault #90 repaired) - per-file annotations are ::error and the step exits 1 when any file matches; the summary step runs with if: always() - no 2>/dev/null on the thing under test - LICENSING.adoc, PROJECT_SUMMARY.adoc, SECURITY.adoc: five U+00A0 replaced with spaces so the first real run is green on merit Verified locally: step exits 0 on this tree, exits 1 with a planted NBSP file. First red must be recorded in standards gate-proofs.

📝 SummarySummary by CodeRabbit
WalkthroughThe Dogfood Gate now fails closed when invisible Unicode characters are detected. It validates its pattern, emits error annotations, and always writes the summary. Documentation files replace specified non-breaking spaces with regular spaces. ChangesInvisible Unicode detection
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The workflow can still report a successful or misleading result when scanning encounters invalid input or when the planted failure check trips early, so the gate may not reliably communicate repository compliance. Merge should wait for these bounded correctness issues to be addressed. Sequence Diagram(s)sequenceDiagram

Initialise the lint status before the planted-pattern guard.
When the grep -aqP check fails, exit 1 runs before findings and ready are written to $GITHUB_OUTPUT. The always() summary then reports Skipped: empty-linter not available instead of the guard failure.

Propagate scan errors from the find -exec scan.
At .github/workflows/dogfood-gate.yml:157, grep -aPrl returns status 2 for invalid UTF-8, but find treats the predicate as false and exits 0. The results file can remain empty, allowing the gate to pass an incomplete scan. Treat status 1 as “no match” and fail for status 2 or other scan errors.

Why
#90 made the invisible-character pattern able to match (
(*UTF),-a), but the step still could not fail: findings were::warningand grep's stderr went to/dev/null. Codacy's MEDIUM on #90 ("gate never fails") was valid. A gate that only warns is not a gate.What
printf 'x\xc2\xa0y' | grep -aqP "$PATTERNS"must fire or the step exits 1. This is the exact fault class fix(ci): the invisible-character gate never matched anything #90 repaired, so it cannot silently return.::errorannotations, exit 1 when any file matches. The summary step now hasif: always().2>/dev/nullon the thing under test.LICENSING.adoc,PROJECT_SUMMARY.adoc,SECURITY.adoc: five U+00A0 replaced with spaces, so the first run of the real gate is green on merit.Proof
