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 logic gaps in the invisible character detection gate by migrating to Unicode codepoint escapes and ensuring binary-flagged files are scanned. Codacy reports that the changes are up to standards.
However, there is a risk that these regex patterns are not verified against actual samples, as no test files containing these characters were added to the PR. Additionally, the current implementation silences standard error, which could hide environment-specific regex compilation failures. Addressing these will ensure the CI gate is both reliable and maintainable.
About this PR
- The PR does not include any automated test cases or a sample file containing the targeted invisible characters (e.g., U+00A0, U+FEFF, C0 controls) to verify the regex patterns and prevent future regressions.
Test suggestions
- Verify detection of Non-Breaking Space (U+00A0) using \x{a0}
- Verify detection of Byte Order Mark (U+FEFF) using \x{feff}
- Verify detection of C0 control characters (e.g., Backspace \x08)
- Verify that files containing NUL bytes are successfully scanned and not skipped
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify detection of Non-Breaking Space (U+00A0) using \x{a0}
2. Verify detection of Byte Order Mark (U+FEFF) using \x{feff}
3. Verify detection of C0 control characters (e.g., Backspace \x08)
4. Verify that files containing NUL bytes are successfully scanned and not skipped

🟡 MEDIUM RISK
Suggestion: Silencing stderr hides potential regex compilation or execution errors. If the grep -P pattern is invalid for the environment's version of grep, or if PCRE errors out on certain file contents, the check will silently report zero findings. Additionally, the -r flag is redundant as find is already providing specific file paths via -type f.

Make the invisible-character scan fail closed.
grep -aPrl can reject PATTERNS because it contains code points above U+00FF. The command suppresses this error, and the empty results file then produces a zero-finding summary. Setting LC_ALL=C.UTF-8 alone does not prevent this failure on GNU grep 3.8. Use a Unicode-capable scanner and fail when EL_EXIT is neither 0 nor 1.

In @.github/workflows/dogfood-gate.yml at line 132, Update the
invisible-character scan in the workflow to use a Unicode-capable scanner that
accepts the PATTERNS code points, and stop suppressing scanner errors. Check
EL_EXIT explicitly and fail the gate when it is neither 0 nor 1, while
preserving the existing handling for successful scans and detected matches.

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.
