aq90_verify_scenario_oracle_and_benign_twin)Evaluates candidate solutions against ScenarioSpec v2.0 invariants and paired benign twins in 0 model calls, checking SWHID preservation, zero local host paths, clean reopen exit codes, and zero false-positive escalation.
0-call invariant predicate checker, local-path scanner & benign-twin specificity verifier
Substrate: db_atomic · p99 Claim Target: ≤ 6 ms · Phase: 87 - 90 4-Tier Parameter Packs, Composable Thin Wrappers & 18x8 Scenario Atlas v2
Counterexample shrinker & clean-environment portability diagnostician
5-Role Component Pod: 0-Call Slot / Solver + OpenSearch / Split-Supervisor (≤4k tok) / Diagnostic Repair + Twin Shim / CPOP + Sister Distiller.
standard_fencedCommit Invariant: Increments lease_epoch atomically (meta.changes === 1) on claim and rejects stale worker heartbeats or completions with 409 fencing_epoch_conflict.
Architectural Problem Solved: Eliminates split-brain duplicate commits across concurrent distributed worker fleets.
