fix(ci): the invisible-character gate never matched anything#42hyperpolymath wants to merge 4 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
The PR successfully updates the invisible-character CI gate to use Unicode codepoint escapes and Perl-Compatible Regular Expressions (PCRE), which fixes the issue where the gate previously failed to match anything.
However, a regression was found: the 'Narrow No-Break Space' (U+202F) was removed during the conversion. I have also recommended adding the (*UTF) verb to the regex to ensure consistent behavior across different environment locales. Codacy analysis indicates the PR is up to standards, but there are no automated tests or sample files provided to verify that these patterns actually catch the targeted characters. Addressing the missing character and adding the UTF verb are necessary before merging.
About this PR
- The PR does not include any automated test cases or fixture files (e.g., sample files containing invisible characters) to verify the effectiveness of the updated patterns or prevent future regressions. It is recommended to add a test step that intentionally includes these characters to confirm the gate fails as expected.
Test suggestions
- Verify detection of a Non-Breaking Space (U+00A0) in a source file
- Verify detection of C0 control characters (e.g., Backspace \x08) in a source file
- Verify detection of a Byte Order Mark (U+FEFF) at the start of a file
- Verify the linter does not skip files containing NUL bytes (using the -a flag)
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify detection of a Non-Breaking Space (U+00A0) in a source file
2. Verify detection of C0 control characters (e.g., Backspace \x08) in a source file
3. Verify detection of a Byte Order Mark (U+FEFF) at the start of a file
4. Verify the linter does not skip files containing NUL bytes (using the -a flag)

⚪ LOW RISK
Nitpick: The -r flag is redundant here because find is already iterating over the file list and passing each file individually to grep.

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.

Make scanner errors fail the job.
The warning for non-zero EL_EXIT allows incomplete results to pass. Also, find -exec grep ... {} \; can return zero when a child grep fails, so EL_EXIT does not reliably detect scan errors. Treat grep status 1 as “no match” and status 2 or greater as an error in both scan paths.

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.
