fix(ci): the invisible-character gate never matched anything#369hyperpolymath 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.

Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to The workflow can still treat files containing invisible characters as clean because its BOM pattern may be rejected by grep, bypassing the gate entirely. Merge should wait until the pattern is made runner-compatible or replaced with a reliable byte- or character-based scan. Poem

Pull Request Overview
The PR successfully addresses the failure of the invisible-character CI gate by migrating to Unicode codepoint escapes (\x{...}) and ensuring that binary/null-byte files are not skipped using the -a flag. The scope of detection has also been appropriately expanded to include C0 control characters while excluding standard whitespace.
While the logic is sound, two optimizations are recommended: first, explicitly enabling UTF-8 mode in the PCRE pattern to ensure consistent behavior across environments; and second, optimizing the find command to batch files into fewer grep processes. The latter is important for performance, as the current implementation could hit CI timeouts in larger repositories. Finally, the required test scenarios for the specific characters (NBSP, BOM, C0, and Null) appear to be missing from the verification process.
Test suggestions
- Verify that a file containing a Non-Breaking Space (U+00A0) is flagged by the linter.
- Verify that a file containing a Byte Order Mark (U+FEFF) is flagged by the linter.
- Verify that a file containing a C0 control character like Backspace (\x08) is flagged.
- Verify that files containing Null bytes (\x00) are scanned and reported rather than skipped by grep.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify that a file containing a Non-Breaking Space (U+00A0) is flagged by the linter.
2. Verify that a file containing a Byte Order Mark (U+FEFF) is flagged by the linter.
3. Verify that a file containing a C0 control character like Backspace (\x08) is flagged.
4. Verify that files containing Null bytes (\x00) are scanned and reported rather than skipped by grep.

🟡 MEDIUM RISK
Suggestion: Performance can be significantly improved by batching files using + instead of \;, which prevents spawning a separate grep process for every file. Additionally, the -r flag is redundant since find already provides file paths, and adding -- is a safety best practice to ensure filenames starting with a hyphen are not interpreted as options.

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.
