Roadmap node: 1-3-3-2. Remaining cleanup and broader edge-write ownership slices

Plan: docs/plans/2026-06-25-rust-hybrid-finalization-cleanup-ownership-contract-plan.md

What to build

Close out the finalization cleanup ownership contract slice after diagnostics and deterministic tests land. Update the plan and roadmap evidence so the next agent can see what cleanup ownership means, what was deliberately not migrated, and what remains for broader edge-write ownership.

This issue should not add new cleanup behavior or resolver semantics. It is a closeout and decision-hygiene slice.

Acceptance criteria

• The plan records closeout evidence and verification commands.
• Roadmap node 1-3-3-2 is updated with completed diagnostics/test evidence.
• Any remaining broader edge-write ownership work is preserved as future work instead of being implied complete.
• The closeout explicitly states that cleanup was not migrated into Rust core.
• Verification commands are recorded in the closing comment.

Blocked by

• Add cleanupOwnership profile contract diagnostics #525
• Add deterministic finalization cleanup ownership contract tests #526

Closing with plan and roadmap closeout complete. 1-3-3-2-1 records the completed cleanup ownership contract diagnostics, while 1-3-3-2-2 keeps broader edge-write ownership as pending future work. Closeout evidence is recorded in docs/plans/2026-06-25-rust-hybrid-finalization-cleanup-ownership-contract-plan.md.
