Why: Preserve the accepted U7 account transaction and identity safeguards while retaining U3 material checkpoint startup ordering and runtime fixes. Evidence: The shared app.go edits are in separate startup/account-maintenance sections; full Go and parent composition checks will be rerun after this merge. Impact: Includes mainline account changes without changing U3 public contracts or model-call budget. Refs: U3 r0.4 resource-preparation sync; Dev main 05b997b
