fix(ci): the invisible-character gate never matched anything#57hyperpolymath wants to merge 6 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.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Add a separate raw-byte check for a leading UTF-8 BOM.
PATTERNS includes \x{feff}, but the scan still relies only on grep -aPrl. A file that starts with a BOM can therefore pass the gate. Check the first three bytes separately, merge those paths with the regex results, and de-duplicate the list before calculating FINDINGS.
Also applies to: 133-133

Pull Request Overview
The pull request successfully updates the invisible-character gate to use PCRE codepoint escapes and expands the detection range, which is a significant improvement over the previous literal byte matching. However, there are systemic issues with how the scan is executed and how failures are reported.
The logic relies on 'grep' returning a specific exit code, but the current implementation of the 'find -exec' loop and the redirection of stderr to /dev/null creates a blind spot where malformed files or regex errors are silently ignored. While Codacy results are up to standards, these execution-level issues should be addressed to ensure the gate is truly effective.
About this PR
- The PR does not include regression test files containing the problematic characters (e.g., U+00A0, U+FEFF, NUL bytes). Without these, it is difficult to verify that the fix works as expected or to prevent future regressions of this CI gate.
Test suggestions
- Missing recommended test scenario: Verify detection of a file containing a Non-Breaking Space (U+00A0)
- Missing recommended test scenario: Verify detection of a file containing a Zero-Width Space (U+200B)
- Missing recommended test scenario: Verify detection of a file containing a Byte Order Mark (U+FEFF)
- Missing recommended test scenario: Verify detection of a file containing a Backspace character (\x08)
- Missing recommended test scenario: Verify that a file containing a NUL byte is scanned and reported rather than skipped as binary
- Missing recommended test scenario: Verify scanner behavior and GITHUB_STEP_SUMMARY when grep encounters an exit error

3. Missing recommended test scenario: Verify detection of a file containing a Byte Order Mark (U+FEFF)
4. Missing recommended test scenario: Verify detection of a file containing a Backspace character (\x08)

🟡 MEDIUM RISK
The captured exit_code is currently unused in the summary step. If the scanner fails to run (e.g., due to a regex syntax error), the job will report success because the results file will be empty. Update the 'Write summary' step to check if the exit_code is non-zero and report a scanner failure if so.

🟡 MEDIUM RISK
The (*UTF) prefix forces strict UTF-8 validation. If a file contains invalid UTF-8 sequences, grep will error out and skip that file. Because stderr is redirected to /dev/null on line 133, these failures are silent, meaning invisible characters in malformed files will go undetected. Consider removing the stderr redirection or adding a mechanism to alert when files fail validation.

Nickel language official syntax K9! source file magic header
💡 Result:
The K9! magic header is not part of the standard Nickel language specification, but rather a mandatory requirement for K9, a separate project that utilizes Nickel as a configuration and validation format [1][2]. K9 is a system for self-validating components that uses Nickel for its logic and contract enforcement [1][3]. In the K9 ecosystem, source files (which use the.k9 or.k9.ncl extensions) are required to begin with the magic bytes K9! on the first line [1][4][2]. This header identifies the file as a K9 component, allowing specialized tools to distinguish them from standard Nickel files [1][5]. In summary: - K9! is not a feature of Nickel itself, but of the K9 Self-Validating Components project [1][6]. - The header is used for file identification and security tier detection (Kennel, Yard, or Hunt) [1][7]. - Standard Nickel files do not require or use this magic header [8].

Do not pass the raw K9! header to Nickel.
nickel typecheck container/deploy.k9.ncl parses standard Nickel syntax, but K9! is not valid Nickel syntax. The command can stop at line 1 before it checks the deployment body. Strip the first line before invoking Nickel, or use a K9 validator that removes the header before the Nickel check.

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.
