fix(ci): close the carry gate on an unclosed HTML comment - #3343
Conversation
The carry-attribution scanner stripped HTML comments with a pattern that required the closing delimiter. An unterminated `<!--` therefore matched nothing and the entire tail stayed in the scanned text, while GitHub renders none of it. That is a divergence between what the gate enforces and what a reader sees, and it runs both ways: a carry claim the gate reads but nobody can see, or one the gate misses because an author closed the comment somewhere the scanner did not expect. pr-quality.cjs already got this right - its comment pattern carries the `(?:-->|$)` alternative for exactly this reason - so this is the two files agreeing rather than a new rule. CodeQL raised it as js/incomplete-multi-character-sanitization (high) on the v2.41.0 promotion. Its own framing does not apply: this output is fed to a regex, never to a renderer, so there is no HTML element injection here. The underlying observation is still correct for what the strip is actually for. Two regression tests, one per direction: carry language after an unclosed comment is ignored, and carry language after a properly closed one is still read - the guard must not swallow the body wholesale. Verification: node --test .github/scripts/*.test.cjs 543 pass 0 fail; bun test tests/ci-workflows.test.ts 135 pass 0 fail.

GitHub Flavored Markdown specification HTML comment <!--> inline code <!-- behavior
💡 Result:
In GitHub Flavored Markdown (GFM), which is based on the CommonMark specification, the handling of <!-- depends entirely on its position and context within the document [1][2]. 1. HTML Block Comments: If a line begins with <!-- (optionally preceded by up to three spaces), it is classified as an HTML block (specifically, Type 2) [1][3]. The parser treats this as the start of an HTML block, and it will continue to consume lines until it encounters the closing string --> [1][3]. Because this is treated as a block-level element, it can interrupt paragraphs [4][3]. 2. Inline Comments: If <!-- appears anywhere else on a line (e.g., preceded by text), it is not treated as the start of an HTML block [1][5]. In these cases, it is simply treated as raw text [1][6]. Markdown parsers generally do not provide a standard mechanism for inline HTML comments to be "hidden" or parsed as structural comments; they are treated as literal text content within the paragraph [1][6]. 3. Behavior of <!-->: The string <!--> is not a standard HTML comment opener. A valid HTML comment must begin with <!-- and end with --> [1][3]. If you write <!-->, it does not satisfy the requirements for an HTML block, and it will be rendered as literal text in the final output [1][3]. 4. Inline Code <!--: When you wrap <!-- in backticks (e.g., <!--), the Markdown parser treats it as an inline code span [7]. The characters inside the backticks are escaped or rendered as literal code, meaning they will never be interpreted as an HTML comment, regardless of where they appear in the document [7]. In summary, <!-- only functions as a structural HTML comment if it starts a line (potentially with minor indentation) and is followed later by --> [1][3]. Any other usage, or usage inside code spans, results in the characters being treated as literal text [1][6][7].

Preserve visible carry claims after inline code and invalid comment-like text.
At .github/scripts/pr-carry-attribution.cjs:75, HTML_COMMENT_RE runs before INLINE_CODE_RE. It therefore consumes `<!--` Supersedes `#2797`. through end-of-text, so assessCarryAttribution returns no missing_coauthor_credit failure. It also consumes <!--> Supersedes #2797., which GFM renders as literal text. Replace the sequential regexes with a left-to-right tokenizer that handles inline code before valid HTML comments. Add both regression cases to .github/scripts/pr-carry-attribution.test.cjs and expect one attribution failure for each. Obtain explicit security review for this .github/** automation change.

@lidge-jun Functional review of exact head 313fe246f is clean: the regex now treats an unclosed <!-- as running to EOF while still stopping at the first real -->, and the focused carry-attribution suite passes 18/18 in an isolated HOME. Protected runtime config hashes are unchanged.
I am not recording the required security approval yet. The repository policy classifies .github gate changes as a security boundary, and the targeted security-diff preflight cannot run on this host because its only Python is 3.10 and neither tomllib nor tomli is installed. I did not install packages or alter Codex configuration to bypass that preflight. Exact-head hosted CI/another maintainer security sign-off can satisfy the remaining gate; the functional patch itself has no blocker from my review.
