Tyrell Build 13 canary-context rereview v4

Reviewed the three-file GUI/effective-user context correction and approved resuming the same bounded canary transaction.

• Scope: read-only review on rdmsm4x; no project source, installation, runtime, LaunchServices, process, or production archive mutation.
• Report: /Users/richh/dev/_handoff/tyrell-build13-stale-app-archive-rereview-v4-20260903.md
• Report SHA-256: 1f445e490ffc59dbd71f7a8cc4a56e5b9e5cb166f0fd53ebfbbc46e7ed9d4dee
• Frozen base/HEAD: 7bd842f51c749473ba274648c26e49ec3e618962
• Tracked delta SHA-256: ccb6df3c55593cc2e1d397ef6fc064f301c253afcee0ba0fda6b690da57536b4
• Verification: exact hashes/status rechecked; syntax passed; focused executable archive contract passed; delta diff check clean.
• Decision: GO to resume the same designated canary; no fleet expansion is implied.
• Outstanding: require the resumed canary's exact LaunchServices, app/helper cardinality, API, archive, and rollback proof.
• Undo: remove this changelog and its handoff report if these review records are no longer required; neither changed product runtime state.
