Verdict: PARTIAL.
Updates the substrate liveness registry with the L1 field substrate audit, including ADR enumeration, module/caller mapping, suite lane evidence, cross-layer contract findings, and downstream notes.
Cleanup: none; no unambiguously dead L1 code was found. Test-only helpers and pulse-only field operators are documented for review instead of deleted.
Verification: python3 -m core.cli test --suite smoke -q; python3 -m core.cli test --suite algebra -q; python3 -m core.cli test --suite pulse -q; python3 scripts/verify_lane_shas.py.
