fix(ci): the invisible-character gate never matched anything#734hyperpolymath wants to merge 9 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.

📝 WalkthroughSummary by CodeRabbit
WalkthroughThe workflow replaces the shell-based invisible-character scan with an embedded Python scanner. The workflow now records scanner errors and fails the job when file reads or UTF-8 decoding fail. ChangesInvisible-character gate
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The workflow's scanner still omits Lean files, so invisible characters in tracked Lean sources can pass the gate undetected.

Pull Request Overview
The PR fixes a non-functional CI gate for invisible characters by using Unicode codepoint escapes and ensuring binary file support. While the intent is correct, the implementation contains a critical logic flaw: grep -P requires the (*UTF) prefix to handle Unicode codepoints above 0xFF. Without this, the command may fail silently due to stderr redirection, resulting in false positives where the CI passes despite the presence of invalid characters.
Additionally, none of the required test scenarios (NBSP, Zero-Width Space, C0 controls, or NUL byte processing) are currently verified by automated tests in this change.
Test suggestions
- Detection of Non-Breaking Space (U+00A0)
- Detection of Zero-Width Space (U+200B)
- Detection of C0 control characters (e.g., Backspace \x08)
- Processing of files containing NUL bytes (\x00) using the -a flag
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Detection of Non-Breaking Space (U+00A0)
2. Detection of Zero-Width Space (U+200B)
3. Detection of C0 control characters (e.g., Backspace \x08)
4. Processing of files containing NUL bytes (\x00) using the -a flag

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.
