Final independent review: plan 02 serialized recovery comparator

Review only. Read pinned approved plan 02, current AGENTS.md, RTK, applicable code-review skill, every Plan 02 report, and complete origin/main...00855fa1667b35502ec66d609a603716d647466d four-file diff. Start fresh; prior churn is not evidence of correctness.

Reproduce every prior P1/P2 bypass. Verify primitive-string guard runs before any object access/trap/getter/method; parsed envelope validation is exact, non-coercing, finite-JSON-only, rejects unknown/missing keys and invalid/empty IDs/flag types; valid false gates retain named reasons; target invariant and invalid source/target order are conservative; invalid manifests are fresh and deterministic. Audit recursive validation/canonicalization for false identity, normalization, mutation, exceptions, stack/size behavior appropriate to local synthetic tooling, and hash determinism. Ensure serialized-request docs match actual API and do not claim raw-v4 support or real recovery.

Run fresh base/live issue/PR state, all 36 comparator tests plus independent adversarial probes, API/auth tests/typechecks, boundaries, narrow Biome/Markdown, import/no-output/diff/four-file scope. Review Standards and Spec axes, including whether 596-line tool/test diff remains proportionate and maintainable for approved procedure.

Write .orchestration/plan-02-final-review.md with findings first and file/line evidence, exact head, commands/results, skips, risks, and publication verdict. Do not edit tracked files, push, open PR, merge, mutate issues, or spawn subagents. Final response at most ten lines.
