PR B: VALIDATING phase + unified ExceptionManager (arch steps 3, 7)
- services/exceptionManager.ts: single taxonomy (timing/data/control/ business/system) with §12 codes, deterministic route() table, and handle() dispatch to retry/DLQ/escalate - services/execution.ts: refactor executePlan to drive the full 12-state machine (DRAFT -> INITIATED -> ... -> VALIDATING -> COMMITTED -> CLOSED) via stateMachine.transition(), with a new validatePhase() that reconciles DLT tx hash + bank message id + per-step amounts before COMMIT; SoD-gated edges use distinct synthetic actors by default - api/plans.ts + index.ts: GET /api/plans/:planId/state returning current transaction_state + full audit trail of transitions - tests/unit/exceptionManager.test.ts: 14 tests for classification + routing matrix 59 tests pass. tsc clean.
