fix(ci): the invisible-character gate never matched anything#497hyperpolymath wants to merge 8 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
This PR correctly addresses the failure of the invisible-character CI gate by transitioning to PCRE-compatible Unicode escapes (\x{...}) and ensuring the scanner processes binary-flagged files. The addition of the -a flag is the most significant change; it prevents GNU grep from outputting 'Binary file matches' text which previously invalidated the filename processing loop.
While the logic changes are sound and the PR is up to standards, there is a lack of test assets (e.g., dummy files containing specific invisible characters) to verify the gate's efficacy. Without these assets, the fix is not explicitly validated within the repository's own test suite, which may lead to regressions.
About this PR
- The PR does not include any test files (e.g., a dummy file containing intentional invisible characters) to verify the fix or protect against future regressions. Validation currently relies on the CI's own output without explicit test assets in the diff.
Test suggestions
- Detect Non-breaking Space (NBSP) U+00A0 using \x{a0}
- Detect Zero-width space (ZWSP) U+200B using \x{200b}
- Detect C0 controls (e.g., Backspace \x08) while skipping allowed whitespace (LF/CR/TAB)
- Successfully scan a file containing a NULL byte (\x00) using the -a flag
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Detect Non-breaking Space (NBSP) U+00A0 using \x{a0}
2. Detect Zero-width space (ZWSP) U+200B using \x{200b}
3. Detect C0 controls (e.g., Backspace \x08) while skipping allowed whitespace (LF/CR/TAB)
4. Successfully scan a file containing a NULL byte (\x00) using the -a flag

Use a byte-oriented scan for malformed UTF-8 files
grep -aPl with (*UTF) can return an internal PCRE error for a scanned file containing malformed UTF-8. It then emits no path. Because the workflow continues under set +e and counts emitted paths, it can report zero findings. If malformed UTF-8 files are in scope, add a byte-oriented C0 scan or use the canonical linter implementation.

@hyperpolymath, this can be fixed.
The probe confirmed the failure on GNU grep 3.8. The Unicode scan returns an internal PCRE error and omits a malformed UTF-8 file. A separate byte-oriented C0 scan reports that file.
Update the workflow as follows:
- Keep the
(*UTF)scan for Unicode code points. - Remove C0 controls from that Unicode pattern.
- Add a second
grep -aPlscan with[\x00-\x08\x0B\x0C\x0E-\x1F]. - Merge and deduplicate both result files before counting findings.
This preserves detection of NBSP, zero-width characters, BOM, and bidi controls. It also reports NUL and other prohibited C0 controls in malformed UTF-8 files.
- Split the current pattern into Unicode and byte-oriented C0 patterns.
- Run each scan against the existing file selection.
- Deduplicate the emitted paths into
/tmp/empty-lint-results.txt. - Validate clean text, NBSP, NUL, and malformed UTF-8 fixtures.

reporting. Preserve the existing no-op result for unchanged content, and only
report “would modify” when the content actually differs.
- Line 273: Update the line handling in apply_modify to preserve CRLF endings

str::lines followed by LF-only joining, and retain the original or dominant line
terminator when rebuilding content.
- Around line 54-58: Update the path validation in the fixer before any mutating
action to canonicalize the repository root and nearest existing target ancestor,
then verify the resolved ancestor remains within the canonical root. Reject
targets that are symlinks, including dangling symlinks, for every mutation path
such as remove, write, modify, and create; preserve the existing
outside-repository error behavior.
- Around line 269-270: Update replace-pattern parsing in apply_modification to
use an explicit escaping or quoting rule that unambiguously separates the regex
and replacement fields while allowing colons in either field, then implement
that rule consistently and document it in the README. Preserve regex replacement
expansion semantics, including $1 and $name, unless the documented catalogue
contract explicitly requires literal replacements.
- Around line 358-370: The apply_and_commit flow must reject an existing
repository with staged changes before modifying the index or creating a commit.
Add a clean-index check before the fix-path updates in commit_changes (or its
caller), comparing the current index against HEAD, while preserving behavior for
clean repositories and isolated checkouts.
- Around line 63-92: The FixAction::Disable branch in Fixer::apply currently
reports success without modifying the target; implement the documented rename of
the target to a .yml.disabled path, or return a failed FixResult indicating the
action is unsupported. Ensure the result accurately reflects whether a file was
renamed and avoid reporting a successful applied fix when no change occurred.

Implement the documented FixAction::Disable transformation
ErrorCatalog::parse accepts disable, and the catalogue documents it as renaming the target to .yml.disabled. Fixer::apply instead returns success without changing the target. The fix flow then reports the fix as applied and may create a pull request with no corresponding file change. Implement the rename, or return an unsupported-action failure.

Check for an unchanged result before the dry-run report.
The dry-run branch runs before the new_text == original_text comparison. If the modification produces no change, dry-run mode still reports "DRY RUN: would modify ...". The preview then lists files that a real run would leave untouched.
Move the unchanged check above the dry-run check.

Define unambiguous replace-pattern: parsing.
The README documents replace-pattern:regex:replacement, but apply_modification splits the value at the first colon. A valid regex such as https://old is therefore parsed incorrectly. Define and document an escaping or quoting rule that supports colons in both fields. The README does not define replacement text as literal, so $1 and $name expansion by Regex::replace_all is not itself a contract violation; use regex::NoExpand only if the catalogue contract explicitly requires literal replacements.

Line splitting discards CRLF line endings.
str::lines splits on \n and removes a trailing \r from each line. Line 322 rejoins with "\n" only. A replace-line:, insert-before:, or insert-after: fix on a CRLF file therefore converts every line ending in the file to LF, not only the edited line. apply_modify sees a changed string, writes the whole file, and apply_and_commit commits a whole-file diff.
Detect the dominant line ending and restore it, or use split_inclusive('\n') so each line keeps its original terminator.
🐛 Proposed fix to preserve the original line ending
let mut lines: Vec<String> = content.lines().map(str::to_string).collect();

Reject repositories with pre-existing staged changes before committing fixes
resolve_repo_path accepts an existing local repository, and no clean-index check runs before apply_and_commit. commit_changes updates only the fix paths, then writes a tree from the entire index. Therefore, unrelated staged entries can enter the automated commit. Reject repositories whose index differs from HEAD before applying fixes, or use an isolated clean checkout.

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.
