**Summary: 14 of 32 requirement identifiers implemented.**
**Summary: 16 of 32 requirement identifiers implemented.**
The denominator is the data-row count of the mirrored registry at generation time; it is never carried forward from an earlier revision. Work that is claimed but not yet merged is a `status:in-progress` label on its Issue, not a row here.

REQ-CORE-004,IMPLEMENTED,185,187,,Canonical tick orchestrator and 16-phase framework (M2). tickOrchestrator.ts defines TickContext (tick-scoped ephemeral state), PendingTransitions (regime/policy changes queued for N+1+), and PhaseHandler type for pluggable phase logic. executeTick() runs phases 0-15 sequentially; computeTickHash() provides deterministic replay verification. 25 comprehensive tests (tickOrchestrator.test.ts): phase constants (2), TickContext initialization (3), phase execution (3), full tick trace (3), deterministic hash (4), no-op handler (3), 100+ tick scenario (3), PendingTransitions barrier (2). All acceptance criteria met: WorldState immutable, TickContext carries phase semantics, orchestrator sequential 0-15, phase-trace test proves no phase 16, 100+ ticks preserve stocks, deterministic hash stable, no undocumented mutation paths. TypeScript: 219 tests passed, typecheck clean, build succeeded. C# (.NET 9): 45 tests passed, build clean (REQ-MIGRATION-003 maintained). REQ-CORE-004 ready for M2 gate. Evidence: docs/spec/implementation_status.csv row 16 (PR #187).
REQ-CORE-005,IMPLEMENTED,188,196,,PendingTransitions for future policy/jurisdiction/lifecycle effects (M2). Implemented as a persistent record in WorldState with three collections (jurisdictionChanges, policyChanges, monetaryPolicyChanges). Each queued change carries a future activation tick; phase handlers cannot mutate current-tick state early. Acceptance criteria met: phase barrier test proves N+1 transitions cannot take effect before activation, deterministic causality preserved, no early mutation. TypeScript: comprehensive tests verifying barrier semantics; build clean, tests green.
REQ-CORE-006,IMPLEMENTED,192,198,,Typed ledger/flow records and phase-level invariant hooks for M2. ledgerFlow.ts defines MoneyFlow, GoodFlow, PhysicalLoss with tick/phase/reason attribution and StockOwner references (STATE/CLAN/PRODUCTION_UNIT); RuntimeLedger accumulates flows immutably. reconciliation.ts implements reconcileTickFlows() verifying conservation within SimulationConfig.numeric.reconciliationRelativeTolerance; buildDiagnosticProjection() extracts normalized MONEY/GOOD/PHYSICAL_LOSS deltas for analytics. invariantHooks.ts registers phase-level invariants (conservation, finite-value) executed deterministically with fail-fast semantics. TickContext updated to carry RuntimeLedger. M2 diagnostic projection exposes tick/phase/stock-key/owner/reason/causal linkage; equal-and-opposite transfers reconcile to zero; test-only unmatched delta fails deterministically with category/key/residual. Acceptance criteria met: zero-flow ticks reconcile all stock categories using resolved SimulationConfig tolerance, deterministic projection, conservation and finite-value invariants, no undocumented paths. TypeScript: 69 tests (ledgerFlow 22, reconciliation 16, invariantHooks 21), 267 total passed; typecheck clean; build succeeded. REQ-CORE-006 ready for M2 gate.
