weichen fb3a8214df Specify U3 stage-six review repairs ...

Why: independent review found in-flight write, API-key admission, lock-order, and cross-instance cursor gaps in the U3 candidate.

Evidence: SELF source review of Backend 4053c4d against approved U3 r1; proposal records triggers, scope, and replay plan.

Impact: request stage-four and stage-five re-review before further affected implementation; no production action.
