Production Readiness Checklist & TODO Burn-down

Status Overview

Current Phase: Implementation Complete Next Phase: Integration Testing

Last Updated: 2026-01-04 — All P0/P1 items implemented.

These items must be formally accepted and “locked” before meaningful code can be written to avoid massive refactoring.

Identity Strategy Finalization
- Confirm ifl:hash (canonical) vs ifl:token (minted) distinction. ✅ SDS-050 §1.1
- Validate UUID v5 deprecation strategy. ✅ ADR-003
- Ref: SDS-050: Semantic Identity & Provenance, ADR-003: Foundational Isomorphic Architecture
- Implementation: libs/sea/domain/src/lib/identity/hash-id.ts
Event Governance Protocol
- Establish CI check flow for Schema Registry (Producer) vs Consumer Contracts. ✅ tools/schema-compat-check.py
- Define “Regime Attribution” payload structure. ✅ SDS-019 §4.1
- Ref: SDS-019: Event Contract Governance
Semantic Observability Standard
- Adopt Privacy/Provenance envelope structure. ✅ SDS-030 §1
- Agree on Signal Mapping rules (Metrics vs Traces cardinality). ✅ SDS-030 §2
- Ref: SDS-030: Semantic Observability Envelope

Essential components required to run the simplest “Hello World” semantic flow.

Knowledge Graph Service (MVP)
- Deploy Oxigraph/RDF4J container. ✅ infra/docker/docker-compose.dev.yml
- Implement SPARQL-first query interface. ✅ services/knowledge-graph/src/api/routes.py
- Implement SemanticDebtCreated -> RDF Projection. ✅ services/knowledge-graph/src/adapters/oxigraph_adapter.py
- Ref: SDS-003: Knowledge Graph Service
Semantic Debt Ledger
- Implement Ledger write API suitable for “Translation Loss”. ✅ schemas/events/governance/
- Define sea-debt Ontology loading process. ✅ ontologies/sea-debt.ttl (155 triples)
- Ref: SDS-016: Semantic Debt Ledger
Case Management Core
- Implement basic Orchestrator for Agentic Workflows. ✅ libs/case-management/
- Ref: SDS-012: Case Management Service

Required for production traffic/SLA, but not for functional POC.

Observability Hardening
- Implement “Sensitive Provenance” hashing. ✅ SDS-030 §3.2
- Implement “Anti-Leakage” timing buckets. ✅ SDS-030 §5.1
- Ref: SDS-030: Anti-Leakage Rules
Event Schema Evolution Guard
- Build the CI tool to strictly enforce Forward/Backward compatibility. ✅ tools/schema-compat-check.py
- Ref: SDS-019: Compatibility Algorithm
Advanced Graph Projections
- Implement “Policy Hotspot” and “Blocker” complexity queries. ✅ SDS-003 Query Cookbook
- Ref: SDS-003: Query Cookbook
