Independent review: Plan 02 round 5

Review only. Worktree: /Users/amruth/orca/workspaces/reactive-resume/issue-3181-recovery-procedure. Exact target head: 4125074f99ad91c161d8a9437259465d4b7f933b. No PR exists. Do not edit tracked files, commit, push, publish, mutate issues, or perform private recovery.

Read current instructions, pinned approved Plan 02, full origin/main...HEAD diff, every implementation/fix/review report, and live issues #3181/#2760 plus branch/PR state. Refresh origin/main and verify target head before review.

Review standards and spec. Independently adversarially verify:

• duplicate JSON member rejection at every depth, both orders, escaped-equivalent names, arrays/objects, and supported serialized source/target resume strings before gates, schema comparison, or hashing;
• lexical scanner correctness for valid JSON escapes, primitives, nested structures, malformed input, deep input, and no executable-object access;
• all safety flags remain literal booleans and fail closed;
• all three manifest IDs reject blank and Unicode control-containing strings while preserving accepted IDs verbatim;
• fresh invalid manifests, deterministic stable hashes, exact-envelope contract, docs, and four-file scope;
• proportionality and maintainability of complete implementation.

Run 59 comparator tests, independent probes, 54 API tests, 21 auth tests, affected typechecks, boundaries, narrow Biome/Markdown, import/diff/scope gates. Report findings first with severity and exact anchors. Write .orchestration/plan-02-review-round5.md; send worker_done with publication verdict. No subagents.
