fix(ci): the invisible-character gate never matched anything#57hyperpolymath wants to merge 1 commit 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.

Pull Request Overview
The PR successfully addresses the issue where the invisible-character gate was ineffective due to incorrect regex matching. By switching to Unicode codepoint escapes and adding the -a flag for grep, the logic is much more robust. Codacy analysis indicates the changes are 'up to standards'.
However, a regression was identified: the 'Narrow No-Break Space' (U+202F), which was handled by the previous byte-sequence implementation, was omitted in the new codepoint list. Additionally, while the logic is improved, there are no automated regression tests (such as a sample file with hidden characters) to ensure this gate remains functional in the future. These points should be addressed before merging to ensure full coverage and long-term stability.
About this PR
- The PR does not include any automated regression tests (e.g., a sample 'malicious' file containing invisible characters) to verify that the CI gate triggers as intended. Without this, future changes to the regex patterns could silently break the gate again.
Test suggestions
- Verify detection of Non-Breaking Space (U+00A0)
- Verify detection of C0 control characters (e.g., Backspace \x08)
- Verify detection of Zero-Width Space (U+200B)
- Verify that files containing Null Bytes (\x00) are scanned rather than skipped
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify detection of Non-Breaking Space (U+00A0)
2. Verify detection of C0 control characters (e.g., Backspace \x08)
3. Verify detection of Zero-Width Space (U+200B)
4. Verify that files containing Null Bytes (\x00) are scanned rather than skipped

🟡 MEDIUM RISK
The Narrow No-Break Space (\x{202f}) was removed during this refactor. Re-adding it and including modern BiDi isolate control characters ensures comprehensive coverage.

⚪ LOW RISK
Suggestion: Using + instead of \; improves performance by batching files. The -r flag is redundant when processing individual files from find.

Include U+202F in the pattern.
The stated U+202A–U+202F coverage stops at \x{202e}. A file containing U+202F is not reported. Add \x{202f} or use a range.

Add a separate raw leading-BOM check.
grep -aP can reject the \x{feff} pattern. Because set +e suppresses this failure, the results file can remain empty and report a false clean result. Inspect the first three bytes separately, then merge any match into /tmp/empty-lint-results.txt.

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.
