fix(ci): the invisible-character gate never matched anything#65hyperpolymath wants to merge 6 commits into
Conversation
MEASURED 2026-08-27: this gate's pattern caught 0 OF 6 invisible-character test
cases. It has never detected an NBSP, zero-width space, BOM, soft hyphen, bidi
override or word joiner.
ROOT CAUSE: the pattern used UTF-8 BYTE sequences (\xc2\xa0) while grep -P
matches CHARACTERS. Bytes c2 a0 are ONE character U+00A0; \xc2\xa0 asks for TWO
characters, U+00C2 then U+00A0, which is never present.
grep -P '\xc2\xa0' -> miss
grep -P '\x{a0}' -> MATCH
Only \x00 worked, being single-byte in both readings.
FIXED: codepoint escapes; C0 control characters \x01-\x08,\x0B,\x0C,\x0E-\x1F
added (TAB/LF/CR excluded); and grep -a, without which grep skips any NUL-bearing
file as binary.
The C0 range matters: a stray BACKSPACE byte made a workflow unparseable in
developer-ecosystem, so it never ran, and this linter called it clean.
Canonical fix: hyperpolymath/empty-linter#70. 1 file(s) here.
VERIFIED: YAML re-parsed, and the corrected pattern was confirmed to catch a real
NBSP before the change was kept.
📝 WalkthroughSummary by CodeRabbit
WalkthroughThe Dogfood Gate workflow now detects invisible characters with Unicode codepoint escapes, includes C0 control characters, scans binary files as text, and fails on blocking findings. ChangesInvisible-character gate
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The workflow’s invisible-character gate can still pass malformed files without reporting them because scan errors may be treated as empty results and a leading UTF-8 BOM may be missed. Merge should wait until scan failures are propagated and BOM bytes are checked explicitly. Poem

Pull Request Overview
While this PR corrects the regex patterns for invisible characters, it contains a significant logic bug in the CI script. The current implementation captures the exit status of the find command rather than the output of the grep scan, meaning the gate will likely report success even if forbidden characters are found.
Additionally, the workflow is currently configured only to issue warnings and does not block PRs upon detection. There are also no regression tests (sample files with target characters) included to ensure the gate works as expected or to prevent future regressions. Codacy analysis indicates the code is up to standards, but these structural CI issues should be addressed to make the gate effective.
About this PR
- The PR lacks automated regression tests. Including sample files containing the targeted invisible characters would verify the fix and ensure the regex continues to work in the future.
- The workflow is currently configured to issue warnings only. If this is intended to be a 'gate', it should explicitly exit with a non-zero status to block PRs when invisible characters are detected.
Test suggestions
- Verify detection of Non-Breaking Space (U+00A0) in a .yml file
- Verify detection of Zero-Width Space (U+200B) in a source file
- Verify detection of C0 Control characters (e.g., Backspace \x08)
- Ensure valid whitespace (TAB, LF, CR) does not trigger the gate
- Verify a file containing a NUL byte is scanned and identified using the -a flag
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify detection of Non-Breaking Space (U+00A0) in a .yml file
2. Verify detection of Zero-Width Space (U+200B) in a source file
3. Verify detection of C0 Control characters (e.g., Backspace \x08)
4. Ensure valid whitespace (TAB, LF, CR) does not trigger the gate
5. Verify a file containing a NUL byte is scanned and identified using the -a flag

135-135: LGTM!
Second layer of the empty-linter fix, scoped by an owner ruling after a census.
DETECTION (layer 1, earlier commit on this branch) sees everything the
pattern covers. ENFORCEMENT (this commit) distinguishes two classes:
BLOCKING C0 control characters and NUL. Never legitimate; proven damage -
a backspace byte made a workflow unloadable (it never ran once),
and LaTeX maths in wiki files was silently mangled where a
generation step turned backslash-b commands into backspaces.
ADVISORY NBSP, BOM, zero-width marks. A gate-lens census found ~2,100
first-party files carry these as legitimate typography in prose;
blocking would fail 2,333 files estate-wide for no safety gain.
Enforcement lives INSIDE the scan step: if the scanner crashes, the step
fails the job directly, so empty counts can never drift into a separate
check that passes silently (review finding). The blocking count re-greps
only the files the full pattern already flagged, so the find expression is
not duplicated and cannot drift.
1 file(s). YAML re-parsed per edit; reverted on any mis-apply.

Fail on blocking-scan errors.
If the blocking grep -qaP returns 2, the if condition treats it as no match. blocking stays zero, and the warning-only path can pass the job. Capture the blocking-scan status and fail when it is greater than 1.

Run the C0/NUL scan independently of UTF-8 validation.
The grep -aPrl scan uses (*UTF). For a file containing an invalid UTF-8 byte and 0x08, it returns status 2 without outputting the file path. The blocking loop then skips that file, so the gate can pass C0/NUL corruption. Run the blocking scan in byte mode with LC_ALL=C and without (*UTF) over all candidate files.

In @.github/workflows/dogfood-gate.yml at line 124, The C0/NUL blocking scan
currently depends on UTF-8 validation and can skip files containing invalid
bytes. Update the PATTERNS-based grep scan in the blocking loop to run
independently in byte mode with LC_ALL=C, removing (*UTF), while preserving
scanning across all candidate files.

Propagate discovery-scan failures.
This changed command no longer records a status, while EL_EXIT is still written and tested later. With the normal shell environment, EL_EXIT is empty. The numeric test then fails inside the if condition, and set -e does not stop the step. A failed grep -P can therefore leave an empty results file and produce a false clean result. Use a wrapper that preserves each grep status, treat status 1 as “no match”, and treat statuses greater than 1 as scan errors. Apply the same handling to the blocking scan.

Measured 2026-08-27: this gate caught 0 of 6 invisible-character test cases. It has never detected an NBSP, zero-width space, BOM, soft hyphen, bidi override or word joiner.
Root cause
The pattern used UTF-8 byte sequences (
\xc2\xa0) whilegrep -Pmatches characters. Bytesc2 a0are one character U+00A0;\xc2\xa0asks for two, U+00C2 then U+00A0 — never present.Only
\x00worked, being single-byte in both readings. The gate ran, passed, and could not see what it exists to see.Fixed
\x01-\x08,\x0B,\x0C,\x0E-\x1Fadded (TAB/LF/CR excluded)grep -a— without it grep skips any NUL-bearing file as binaryThe C0 range matters: a stray backspace byte made a workflow unparseable in
developer-ecosystem, so it never ran — and this linter called it clean.Canonical fix: hyperpolymath/empty-linter#70. 1 file(s) here.
Verified: YAML re-parsed, and the corrected pattern was confirmed to catch a real NBSP before the change was kept.
