+## Implementation Status
+
+### Phase 1 – Deterministic evaluation core (Complete)
+- DSL compiler with caching, static analysis, runtime guardrails
+- Batch evaluator with deterministic ordering, change-stream inputs
+- Append-only effective findings ledger
+- Explain trace generation with evidence linking
+
+### Phase 2 – Orchestration & incremental runs (In Progress)
+- Run scheduler with job leasing, fair-share per tenant/policy
+- Determinism hash verification and replay validation
+- Incremental delta processing with change-stream integration
+- Time-travel snapshots and resume cursors
+
+### Phase 3 – Policy Studio workflows (Planned)
+- Policy registry with draft/review/approved lifecycle
+- Signed promotion pipeline with multi-step approvals
+- Console integration: editor, simulation, approvals, explain viewer
+- CLI parity for policy management operations
+
+### Phase 4 – Simulation & approvals (Planned)
+- Diff/simulation APIs with rationale breakdown
+- Approval queues with change management workflows
+- Integration with CLI/Console for policy previews
+
+### Phase 5 – Exports & offline parity (Planned)
+- Policy bundles with deterministic manifests
+- Explain archives for audit and review
+- Offline Kit assets with signed packages
+- Export Center integration
+
+### Phase 6 – Observability & hardening (Planned)
+- Metrics: run duration, evaluation verdict counts, simulation latency
+- Guard violation detection and alerting
+- Incident response runbooks and compliance attestations
+
+### Key Acceptance Criteria
+- Evaluation deterministic across runs; effective findings materialised only by Policy Engine
+- Incremental runs handle deltas within ≤5 min SLA; replay verification succeeds
+- Policy Studio supports full lifecycle with signed promotions and explain traces
+- Exports reproducible with signed manifests; Offline Kit delivers same tooling
+- Guardrails prevent forbidden IO; static analysis integrated into CI
+
+### Technical Decisions & Risks
+- Non-determinism prevented via strict static analysis, runtime guards, replay tests
+- Policy drift managed through simulation previews, approval workflow, audit trail
+- Scaling handled via sharded workers, incremental deltas, caching, queue fairness
+- Guard bypass prevented by analyzers in CI and runtime rejection of forbidden operations

 ## Epic alignment
 - **Epic 2 – Policy Engine & Editor:** deliver deterministic evaluation, DSL infrastructure, explain traces, and incremental runs.
 - **Epic 4 – Policy Studio:** integrate registry workflows, simulation at scale, approvals, and promotion semantics.
