Independent rereview: Plan 02 hosted feedback fix

Review only in /Users/amruth/orca/workspaces/reactive-resume/issue-3181-recovery-procedure. Exact target head: 325d1fcd1e2ea3744896c1688c6f6c0bfc3dd5ce. Do not edit tracked files, commit, push, reply, resolve threads, publish, merge, or mutate issues.

Read current repository instructions, pinned approved Plan 02, prior review reports, hosted-review fix report, full origin/main...HEAD diff, live PR #3460, and all four unresolved hosted threads. Refresh base and verify exact head. Run root Intent inventory and load matching review skill if any; no subagents.

Review Standards and Spec independently. Verify especially:

caseId, sourceResumeId, and non-null targetResumeId reject all Unicode control (Cc) and format (Cf) characters, including embedded and format-only U+200B, U+2066, U+202E, and U+FEFF values;
safe accepted identifiers remain byte-preserving and unnormalized;
strict current-v5 canonical equality and duplicate-member scanner remain fail-closed;
autofix cleanup is retained and no scope expansion or contract weakening occurred;
migration guidance exactly matches executable validation and does not imply raw-v4 conversion or real recovery;
Codacy scanner-complexity and scanner-coverage comments are non-actionable or already satisfied, and relaxing canonical equality would violate approved direction;
all 83 comparator cases and independent adversarial probes are mutation-sensitive enough to catch removal or partial application of the Cf guard.

Run focused comparator/API/auth tests, affected typechecks, boundaries, narrow non-writing Biome/Markdown lint, static-import, diff/base/scope gates, and any small independent probes needed. Report findings first with severity and anchors, publication verdict, exact head, and hosted-thread disposition in .orchestration/plan-02-hosted-rereview.md; send worker_done.
