Replace the repeatedly patched line scanner with the existing exact Marked 17.0.6 GFM lexer. Preserve real legacy values and silent current-thread label deltas while excluding quoted, nested, HTML and multiline-code declarations and upgrade-source title fallback. Install the complete one-package locked graph with scripts disabled and verify triage before minting its existing write token.
Contract-Neutral: Replace the issue metadata scanner within the existing silent classification contract; no product runtime, API, rendered Pulse UI, permissions, retest or disposition-authority change.
