Master Roadmap v3.1
Status: LOCKED (Enterprise Architecture Freeze)Charter Source: CLARITY_ENTERPRISE_ENGINEERING_CHARTER.md
1. Phases
| Phase | Scope |
|---|---|
| Phase 8 | Wizard Completion |
| Phase 8S | Ledger Hardening (sub-phase of Phase 8) — process_runs, inputs_hash, exactly-once enforcement |
| Phase 9 | Deterministic Math Engine |
| Phase 10 | Audit Outputs |
| Phase 11 | Governance & Enterprise Enhancements |
2. Core Principles (Frozen)
- Upload → Map → Discover → Configure — Ingestion wizard flow
- Exactly-once processing — Future process_runs ledger enforces idempotency
- Deterministic Python math — Decimal-only; no floats in computation
- Stage snapshots — Immutable, run-scoped; no destructive updates
- Dashboards read stage outputs only — No direct reads from ingestion tables (transaction_events_raw, stage1_bridge_rows)
- Explain-this-dollar lineage — Traceability from input to commission
- No label joins in payout logic — All joins on canonical business_id
- No silent inference — Explicit config; no implicit defaults
- Template/config driven SaaS — No tenant hardcoding; behavior from template registry
3. Partitioning Clarification
As-built: stage1_bridge_rows partitions byDATE(created_at).
Future enhancement (not implemented): Partition by period_label for period-scoped query performance. Do not imply period_label partition currently exists.
4. Enterprise Extensions (Future)
- Pending Inventory — Future
- Manual Match Memory — Alias mapping
- Variance Engine — Expected vs actual
- Commission SaaS layer — Built on forensic engine foundation
5. Stop Conditions
- No floats in computation
- No mutable stage snapshots
- No PHI in logs
- No direct reporting from raw ingestion
- No semantic drift in /process
6. Phase State Transitions
| Phase / Milestone | Status | Notes |
|---|---|---|
| Phase 8S / PR3-D | COMPLETE | See closure block below. Tag: pr3d-stage3-write-proof-2026-02 |
| Phase 9 | ACTIVE | Deterministic Math Engine |
PR3-D Closure (Phase 8S)
✅ PR3-D — Stage3 Write & Idempotency Proof — CLOSED
Scope: PR3-D validated deterministic Stage3 writes, replay idempotency, and ledger invariants for/process in production. This closes the final blocker in Phase 8S (Ledger + Stage3 write path).
Deployed SHA: 41c1f1e54cbe9b47a1a7466cbb56836ebd30850f (verified via /api/v1/healthz)
Proof batch: tenant creative_benefit_strategies_sandbox, batch 52fc3703-7273-4ddd-ad0d-9b906545e53b, period 2026-02-01, discovery_count 2
Run: run_id be1e5e13-8635-483b-8f8b-b696d7f2cb84, status SUCCEEDED, stage3_row_count 2
Ledger invariants: bridge_valid_count_for_run 5, stage1_row_count 5, stage3_row_count 2; verifier [PASS] All PR3-D ledger fields populated, status=SUCCEEDED, invariants satisfied
Replay: Same run_id, same stage3_row_count, same stage3_snapshot_ref; ledger re-verification PASS. Exactly-once semantics confirmed.
Fixes: Stage3 partition window validation, deterministic run-scoped Stage1, VIEW write guard, Decimal-safe processing, proof harness ledger SSOT, discovery SSOT alignment. No schema drift, no idempotency regression, no Decimal→float regression.
Phase 8S — COMPLETE. Phase 9 — ACTIVE.
