recordSwapOutcome abstract method

Future<bool> recordSwapOutcome({
  1. required String swapId,
  2. required SwapOutcome outcome,
})

Pin an OBSERVED terminal outcome into an in-flight swap record (#367) — call when the tracking stream reports a TERMINAL status, so the home row renders the truth even if the user was away at observation time (deleting on observation erased outcomes the user never saw — durably, if the process died in the gap). First-wins + idempotent (false for an absent / lapsed / already-pinned id). Display-only state.

Implementation

Future<bool> recordSwapOutcome({
  required String swapId,
  required SwapOutcome outcome,
});
