The 1.3 text below is kept verbatim as history. Where the disposition is Reframed, Superseded or Parked it is not the GGA oracle; use the replacing scenario. A Parked scenario has no GGA feedback and stays a Proposed carry-forward. The status stays Not executed. Register: Scenario-Dispositions.
Given
Two B users submit against the same opportunity and the client may lose a successful response.
When
Race submissions; retry key/payload after lost response and after access removal; reuse key with changed payload; try a separately authorised reopened attempt.
Then / oracle
One active EOI per B/opportunity. Scope idempotency to actor, command and attempt/generation plus key and payload hash. Check current authority before replay; never replay protected data to revoked actor. Same authorised request returns original result; changed payload fails. A permitted reopen uses new attempt/key, never old acceptance.
Evidence required
Database uniqueness; idempotency request hash/result; event-recipient uniqueness.
Decision dependency (verbatim)
Q05/Q07: active states, key retention and whether reopen/resubmit exists. No automatic resubmission is approved.
