Replaces the single shared per-stage retryCount (reset on TransitionExecuted,
shared across all post-stage gates) with a per-gate budget. Motivated by run
2e468f9f, where a promising freestyle run was terminally FAILED because the
contract gate burned all 3 shared retries on one trivial miss before the
semantic-review gate ever ran.
- StageExecutionResult.Failure gains a `gate` id; each gate tags its failures.
- OrchestrationState gains gateRetryBudgets / gateFailureFingerprints /
gateSalvageUsed (all rebuilt from events, reset per-stage on TransitionExecuted).
- FailureFingerprint normalizes+hashes the failure reason; RetryCoordinator.decide
charges a gate's budget only when the fingerprint is unchanged (no progress),
so a moving run is never penalised. Returns Retry | Exhausted.
- Hybrid exhaustion: deterministic gates fail; the review gate consults a
SalvageJudge (LLM, or a deterministic allow-one-reset fallback), recorded as
RetrySalvageDecidedEvent (invariant #9). CONTINUE resets the gate budget once;
a second exhaustion is terminal.
- Review gate is now the sole authority on review-retry termination; the old
REVIEW_BLOCK_RETRY_CAP is repurposed as a high absolute backstop only.
- ServerModule escaped-exception path now records a truthful terminal
WorkflowFailed (real stage/reason/retryExhausted) via recordUnhandledFailure.
Tests: DefaultRetryCoordinatorTest (fingerprint charging) +
GateRetryBudgetExhaustionTest (deterministic exhaust / review CONTINUE-then-
terminal / review FAIL / null-judge fallback) + reducer coverage.
