fix(ci): the invisible-character gate never matched anything#74hyperpolymath wants to merge 3 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 addresses a critical flaw in the 'invisible-character' CI gate, which was previously ineffective due to incorrect character escaping. The switch to Unicode codepoints and the addition of the -a flag for NUL byte processing significantly improves the gate's coverage. Codacy reports the changes are up to standards.
While the technical fix is sound, two concerns should be addressed before merging: the suppression of standard error in the grep command on line 143 may hide regex engine errors, and the absence of committed test fixtures (files containing the targeted characters) leaves the gate vulnerable to future regressions. It is recommended to include the test cases mentioned in the PR description as repository artifacts.
About this PR
- The PR description mentions '0 of 6 invisible-character test cases' were caught, but these test cases are not included in the repository. To ensure the gate remains functional and to provide a baseline for future changes, please commit these test files as automated test fixtures.
Test suggestions
- Verify detection of Non-Breaking Space (U+00A0)
- Verify detection of Zero-Width Space (U+200B)
- Verify detection of C0 control character like Backspace (\x08)
- Verify detection of NUL byte (\x00) using the grep -a flag
- Verify detection of Byte Order Mark (BOM) (U+FEFF)
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify detection of Non-Breaking Space (U+00A0)
2. Verify detection of Zero-Width Space (U+200B)
3. Verify detection of C0 control character like Backspace (\x08)
4. Verify detection of NUL byte (\x00) using the grep -a flag
5. Verify detection of Byte Order Mark (BOM) (U+FEFF)

🟡 MEDIUM RISK
Suggestion: Optimize the execution and improve error visibility by using + instead of \; and removing the redundant -r flag (since find provides individual paths). Most importantly, remove 2>/dev/null so that regex engine failures or system errors are logged in the CI output rather than failing silently.

143-143: LGTM!
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.

grep -Pdoes not strip a leading UTF-8 BOM. PCRE2 treats the BOM as input, so the stated failure mechanism is false.

GNU findutils manual -exec action exit status find command returns nonzero child exit status find exit status
💡 Result:
The GNU find command returns a nonzero exit status if errors occur during its execution [1][2][3]. If all files are processed successfully, it exits with a status of 0 [1][3][4]. Regarding child processes and exit statuses: 1. Executed Commands (-exec... +): If the find command uses the -exec... + variant to run commands, and any of those command invocations return a nonzero exit status, the find command itself will return a nonzero exit status [4]. 2. General Error Handling: The find utility maintains a broad definition of "errors" that lead to a nonzero exit status, such as being unable to stat a file or directory [1][3]. If a nonzero exit status is returned, users are cautioned not to rely on the correctness or completeness of the command's results [1][2][3]. 3. Specific Actions: - The -delete action is explicitly documented to set find's exit status to a nonzero value if the removal fails [1][2][3]. - The -quit action causes find to exit immediately; if no errors have occurred, it exits with a return value of 0 [5][1]. Any command lines built by -exec... + or -execdir... + are invoked before find exits, even if -quit was called [5][1]. Because the exit status description is intentionally broad, a nonzero status serves as a general indicator that an error occurred, but it does not specify which part of the operation failed [1][3].

GNU findutils manual "-exec" "\;" nonzero exit status find child command
💡 Result:
In GNU findutils, the behavior of the -exec command; primary regarding the exit status of the child command is as follows: The -exec command; primary evaluates as true only if the executed command returns an exit status of 0 [1][2]. If the command returns a non-zero exit status, the primary evaluates as false [1][2]. This is distinct from the -exec command {} + variant, which always evaluates as true regardless of the child command's exit status [3][4]. However, for the + variant, if any invocation of the command returns a non-zero exit status, the overall exit status of the find utility itself will be non-zero [3][1][5]. In summary: -exec command;: Evaluates to true if the command succeeds (exit status 0) and false otherwise [1][2]. -exec command {} +: Always evaluates to true, but a failure (non-zero exit status) in the child command will cause the find process to exit with a non-zero status [3][1][5].

Fail the job when the scan fails.
When EL_EXIT is non-zero, emit an error and exit before evaluating blocking or FINDINGS. Otherwise, the gate can pass with incomplete results. Track each grep status explicitly because -exec grep ... {} \; only makes the find expression false when grep fails.

132-132: 🎯 Functional CorrectnessDo not add a separate leading-BOM check.
\x{feff}already matches a leading U+FEFF, so the reported clean result cannot occur with this pattern.
1 participant
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.
