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 now detects invisible characters with Unicode code point escapes, scans binary files as text, and fails when files contain C0 control characters or NUL bytes. Other invisible-character findings remain advisory. ChangesInvisible-character gate
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The gate can still pass malformed files when invalid UTF-8 precedes control or NUL bytes, and leading BOMs may be skipped entirely. Merge should wait until these cases are handled with an independent byte-safe scan or fail-closed behavior and an explicit leading-BOM check. Poem

It does not show the required matching updates to stdlib/ByteDetector.affine and config.ncl, or the separate leading-BOM check described in issue Resolution Update stdlib/ByteDetector.affine and config.ncl with the same C0-control range. Preserve or add the separate byte-wise leading-BOM check. Apply the corrected pattern to the required estate-wide copies, or provide evidence that those copies are outside this issue's scope.

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.

grep -aPrlcan omit a UTF-8 BOM at byte offset 0. A file that starts withEF BB BFis therefore absent from/tmp/empty-lint-results.txt, so its warning and finding count are missed. Add the required prefix check and deduplicate the combined paths before calculatingFINDINGS.

118-129: Add the separate leading-BOM check.The current
grep -aPrlscan still omits a UTF-8 BOM at byte offset 0. Add a prefix check, append its paths to/tmp/empty-lint-results.txt, and de-duplicate paths before calculatingFINDINGSand emitting annotations.

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.
