Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The PR improves parsing performance and prevents hidden or unterminated comments from bypassing quality checks, but an unterminated quoted plugin source can still be misclassified and produce an incorrect repair suggestion. Merge readiness is moderate because the PR also retains workflow permission and concurrent-push risks that require explicit owner attention before merging. Possibly related PRs

malformed quoted marketplace test to inject the existing locateCurrent seam with
a deterministic stub, preventing the default locateCurrentBundledMarketplace
filesystem discovery from running while preserving the assertion and cleanup.

- Line 62: Update the regex used by readMarketplaceTable to replace the
overlapping bare-value fallback [^#]+? with the linear [^\s#]+ form, preserving
quoted-value parsing and trailing comments. Add a regression test covering a
malformed quoted value followed by a long run of spaces and a non-space
terminator, ensuring diagnoseCodexBundledPlugins remains responsive.

GFM treats fenced-code contents as literal text, so a `<!--` inside a code sample never opens an HTML comment. Both quality gates stripped comments BEFORE removing code regions, so an unclosed comment-like literal in an example ran through EOF and swallowed everything after it. Two real rejections follow from that: - pr-quality: a GUI PR whose screenshot appeared after such an example lost its evidence and was blocked for a missing screenshot. - issue-quality: an issue whose goal contained such an example had the section emptied and was rejected as "too vague to act on", which the triage workflow can escalate to an auto-close. pr-quality now removes fenced code first, which is safe there because that function only asks whether rendered image syntax exists. issue-quality-core cannot simply delete fences: their contents are legitimate reproduction evidence that emptiness and duplicate detection need to see. It now masks fenced blocks and inline code spans, strips comments from what remains, and restores them. Regressions added on both sides, each paired with a negative case proving a genuine HTML comment is still stripped. Without the fix 2 of 190 fail; with it all 190 pass.
Re-review found the first fix both incomplete and dangerous. DANGEROUS: the masker combined a variable-length delimiter capture, a lazy whole-input scan and a backreference, which backtracks catastrophically. A 60,488-character template-shaped body took 10.5s - inside an issue-automation trust boundary anyone can post to. Measured now: 60k unclosed fence 0ms, 20k inline spans 4ms. INCOMPLETE: it required the closing fence to match the opener's length exactly and only masked single-line code spans. GFM allows a LONGER closing fence and allows line endings inside a code span, so both cases still let a comment-like literal run to EOF and swallow the visible section below it. Replaced with a single-pass scanner that walks the string once: fenced blocks (<=3 space indent, >=3 backticks or tildes, closing run of at least the opening length), inline spans (a run of N backticks closed by the next run of exactly N), and HTML comments outside both. Also removed a duplicate definition of the function that the previous patch left behind - the stale regex copy was the one actually being called, which is why the longer-fence case still failed after the first attempt. Regressions: longer closing fence, multiline code span, and a bounded-time assertion on adversarial input. 193 pass; reverting the source fails 1.

Summary
CodeQL findings addressed
This closes the 10 validated findings from the exported scan:
The other 74 open alerts from that export were triaged separately as false positive, non-actionable, or test-only, so this PR does not churn unrelated code just to make CodeQL green.
