Retrieval Module - Future Enhancements

Scope

• transition EPIC 1 retrieval contracts from scaffold to production behavior
• deepen reliability, observability, and policy controls across retrieval layers
• complete benchmark-backed readiness gates for release integration

Design Constraints

• keep contract compatibility within the active major release line
• preserve explicit dependency sequencing with EPIC 2 and EPIC 3
• fail safely when optional backend capabilities are unavailable

Planned Enhancement Themes

1. runtime hardening for error handling and degraded-mode behavior
2. deeper contract and scenario test coverage for multi-stage retrieval flows
3. benchmark-backed performance envelopes and release gates
4. clearer operational diagnostics for policy/governance decisions

Validation Strategy

• expand tests/epic1_retrieval/ for contract, edge-case, and integration scenarios
• implement benchmarks/epic1_retrieval/ for stage-level and end-to-end profiling
• promote only after roadmap phase-gate criteria are satisfied

RAG-Readiness Audit Backlog (2026-09-23)

• Retrieval-Scopes zwischen README/ROADMAP/Future Enhancements konsolidieren (Target: Q4 2026)

  • Rationale: Aktuelle Modultexte enthalten widerspruechliche Reifeaussagen (Scaffold vs. fortgeschrittener Rollout).
  • Umsetzungsschritte: (1) deklarativen Ist-Scope fuer src/retrieval festschreiben, (2) nicht gelieferte EPIC-Surfaces explizit als geplant markieren, (3) Verweise auf src/rag/src/index fuer aktive Retrieval-Pfade klaeren.
  • Abhaengigkeiten: src/retrieval/README.md, src/retrieval/src/README.md, src/retrieval/ROADMAP.md.
  • Messbares DoD: Keine widerspruechlichen Reifestatus mehr in retrieval-nahen Moduldokumenten; alle Claims source-verifizierbar.

• Verbindlicher Delivery-Entscheid fuer EPIC1 Retrieval-Sources (Target: Q1 2027)

  • Rationale: Fuer RAG-Planbarkeit muss klar sein, welche Retrieval-Surfaces real geliefert werden oder dauerhaft out-of-scope bleiben.
  • Umsetzungsschritte: (1) pro geplanter Source (ann_frontdoor, tensor_midlayer, graph_validator, ...) Entscheidung implementieren vs retiren, (2) Gate-Kriterien je Entscheidung, (3) CMake/Test-Mapping.
  • Abhaengigkeiten: src/index, src/query, src/rag, tests/epic1_retrieval.
  • Messbares DoD: 100% der EPIC1-Sources haben Status + Termin + Test-Gate; kein "unassigned"-Eintrag.
