fix(ci): the invisible-character gate never matched anything#58hyperpolymath wants to merge 2 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.

Pull Request Overview
While this PR correctly identifies the failure of the previous byte-sequence matching, the implementation of Unicode escapes (\x{...}) in grep -P defaults to byte-mode. This prevents the detection of multi-byte UTF-8 characters in standard source files.
Additionally, the CI gate execution is currently inefficient, spawning a new grep process for every file scanned. Implementing the suggested performance improvements and the PCRE UTF-8 verb is necessary to ensure the gate is both effective and performant. There are no automated tests included to verify these CI logic changes.
About this PR
- The PR lacks automated test cases or sample 'bad' files to verify that the updated regex patterns and grep flags correctly trigger the gate within the CI environment. Consider adding a small set of test files containing targeted invisible characters.
Test suggestions
- Verify detection of Non-Breaking Space (U+00A0) using the new codepoint escape syntax.
- Verify detection of C0 control characters such as Backspace (\x08) or Vertical Tab (\x0B).
- Verify that files containing NUL bytes (\x00) are scanned rather than skipped (validating the -a flag).
- Verify that allowed whitespace characters like TAB (\x09), LF (\x0A), and CR (\x0D) do not trigger findings.
- Verify detection of Unicode-specific invisible characters like Zero Width Space (U+200B) and BOM (U+FEFF).
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify detection of Non-Breaking Space (U+00A0) using the new codepoint escape syntax.
2. Verify detection of C0 control characters such as Backspace (\x08) or Vertical Tab (\x0B).
3. Verify that files containing NUL bytes (\x00) are scanned rather than skipped (validating the -a flag).
4. Verify that allowed whitespace characters like TAB (\x09), LF (\x0A), and CR (\x0D) do not trigger findings.
5. Verify detection of Unicode-specific invisible characters like Zero Width Space (U+200B) and BOM (U+FEFF).

🔴 HIGH RISK
Suggestion: The PCRE patterns using the \x{...} syntax for Unicode code points (like Zero-Width Space \x{200b}) will fail to match multi-byte UTF-8 characters because grep defaults to byte-mode. To ensure these are correctly detected, you should prefix the regex string with the (*UTF8) PCRE verb.

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.
