fix(ci): the invisible-character gate never matched anything#46hyperpolymath 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.
📝 WalkthroughSummary by CodeRabbit
WalkthroughThe empty-linter workflow now uses Unicode code-point patterns and scans binary files as text. It treats NUL and C0 control characters as blocking findings, while other invisible Unicode characters remain advisory. ChangesInvisible-character gate
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The workflow now detects more invisible characters, but it can still miss affected files when paths contain newlines and may not detect a UTF-8 BOM at the beginning of a file. These gaps can let malformed files pass the gate, so merge should wait for both cases to be handled or explicitly accepted by the owner. Poem

Pull Request Overview
The PR correctly addresses the failure of the invisible-character gate by moving from byte sequences to Unicode codepoint escapes and ensuring files with NUL bytes are not skipped. Codacy reports the changes are up to standards.
However, there are two primary risks: the lack of automated test files to verify that these patterns actually catch the intended characters, and potential environment-specific behavior of the PCRE engine. Implementing the suggested efficiency and observability improvements in the workflow file is recommended to prevent future silent failures.
About this PR
- There are no automated test cases or sample files containing invisible characters (e.g., a known-bad fixture file) included in this PR. Without these, it is difficult to verify that the new patterns effectively catch the targeted characters or to prevent future regressions.
Test suggestions
- Verify detection of Non-Breaking Space (U+00A0)
- Verify detection of Byte Order Mark (U+FEFF)
- Verify detection of C0 controls (e.g., Backspace \x08)
- Verify NUL byte (\x00) detection does not cause grep to skip the file
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify detection of Non-Breaking Space (U+00A0)
2. Verify detection of Byte Order Mark (U+FEFF)
3. Verify detection of C0 controls (e.g., Backspace \x08)
4. Verify NUL byte (\x00) detection does not cause grep to skip the file

🟡 MEDIUM RISK
Suggestion: The -r flag is redundant when grep is called by find on specific files. Using + instead of \; improves performance by bundling multiple file arguments into fewer processes. Additionally, removing the stderr redirection (2>/dev/null) is recommended to ensure regex compilation or encoding errors are surfaced in CI logs.

Suggestion: To ensure consistent Unicode matching across different runner environments, explicitly enable UTF-8 mode in the PCRE engine by prefixing the pattern with (*UTF).

Add a separate BOM check.
The grep -aPrl scan does not detect UTF-8 BOM bytes at byte offset 0 or later, despite PATTERNS containing \x{feff}. Add a raw-byte BOM check and merge its paths into /tmp/empty-lint-results.txt. De-duplicate paths before counting findings.

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.

118-118: Add the separate raw-byte BOM scan.The required byte-level UTF-8 BOM check is still absent.
\x{feff}does not detect a BOM thatgrepstrips at byte offset 0. Scan for\xEF\xBB\xBFseparately, then merge and de-duplicate its paths with the PCRE results.
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.
