fix(ci): the invisible-character gate never matched anything#69hyperpolymath wants to merge 5 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.

WalkthroughThe dogfood gate now detects invisible characters with Unicode code-point patterns and scans binary files with ChangesInvisible-character gate
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟠 High · up to The workflow still has correctness gaps that can let forbidden characters pass undetected: invalid UTF-8 files may be skipped, leading BOMs are not separately checked, and filenames containing newlines can be misprocessed.

Pull Request Overview
This PR fixes the invisible-character CI gate, which previously failed to detect most targeted characters. The transition to PCRE codepoint escapes and the inclusion of C0 control characters effectively address the functional gap. Codacy results indicate the changes are up to standards.
While the logic is improved, there are opportunities to optimize the execution and increase the reliability of the check. Specifically, the regex should explicitly enable UTF-8 mode to ensure consistency across environments, and the file scanning command should be batched for performance. There is also a risk of silent failures due to error suppression that should be addressed to ensure the CI gate remains trustworthy.
About this PR
- Although the PR description mentions manual verification, there are no automated regression tests (e.g., a test file containing these specific invisible characters) included in the PR to ensure the regex logic remains functional in the future.
Test suggestions
- Detect Non-Breaking Space (U+00A0) using codepoint escape
- Detect C0 Control characters such as Backspace (\x08)
- Detect Zero-Width characters (ZWSP, ZWJ, ZWNJ)
- Scan files containing NUL bytes without 'grep' skipping them as binary
- Detect Byte Order Mark (U+FEFF)
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Detect Non-Breaking Space (U+00A0) using codepoint escape
2. Detect C0 Control characters such as Backspace (\x08)
3. Detect Zero-Width characters (ZWSP, ZWJ, ZWNJ)
4. Scan files containing NUL bytes without 'grep' skipping them as binary
5. Detect Byte Order Mark (U+FEFF)

separately detect a leading UTF-8 BOM byte sequence using head -c 3 and cmp

Add the separate byte-wise leading-BOM check.
The \x{feff} pattern is not sufficient for a BOM at byte offset zero because grep strips a leading BOM before matching. The -a option only changes binary-file handling. A file beginning with EF BB BF can therefore be omitted from /tmp/empty-lint-results.txt and pass the gate.
Add a byte-wise head -c 3 and cmp check before writing the results, then merge and deduplicate its paths with the PCRE results. Add a regression test for a leading BOM.
Suggested check
if head -c 3 "$filepath" | cmp -s - <(printf '\357\273\277'); then
printf '%s\n' "$filepath"

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.

126-137: Add the separate leading-BOM check required by Issue#70.The current

126-137: Make the Unicode matching mode explicit.
PATTERNSincludes code points above0xFF, but this step sets neitherLC_CTYPE/LC_ALLnor(*UTF). Verify theubuntu-latestlocale or make the mode explicit so the Unicode matches do not depend on the runner image. GNUgrepderives encoding fromLC_CTYPE, and PCRE2 requires UTF mode unless the application enables it. (gnu.org)

set +e, redirects errors to/dev/null, and convertsEL_EXIT != 0into a warning. The blocking re-scan has the same gap:grep -qaPis anifcondition, so status2does not triggerset -eand falls through as “not blocking”. An incomplete scan can therefore pass withblocking=0.

Use NUL-delimited paths for the blocking pass.
grep -l writes newline-delimited file names, while read -r also uses LF as the delimiter. A tracked file whose name contains LF is split into multiple bf values. The blocking re-scan can then miss C0/NUL content and report incorrect paths. Use grep -Zl with read -r -d '', and update FINDINGS and the warning loop to use the same delimiter.

Run the blocking C0/NUL scan independently of the UTF-8 scan.
(*UTF) can make PCRE2 reject a file with invalid UTF-8 before it matches a C0 or NUL byte. The first scan then omits the file from /tmp/empty-lint-results.txt, so Lines 150-156 do not inspect it. grep -a does not change this behaviour.
Use a byte-oriented C0/NUL scan for every candidate file, or make UTF-8 scan errors fail the job. Do not allow Lines 170-172 to turn incomplete results into a successful job.

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.
