[P2] EPIC: Retentive Knowledge Model foundation (v2, 10 sub-items)

[se-jo-ma]

Epic scope

v2 RKM foundation per design-docs/05-ecosystem-roadmap.md:443-458 (weeks 11-14). Single umbrella; each sub-item is its own PR.

Sub-items

• Event-sourcing design spike — validate shared event log for Blackboard persistence (prerequisite for Weakness 5 mitigation, design-docs/05-ecosystem-roadmap.md:195-231)
• Relationship facts (templates + initial manual authoring) — design-docs/03-living-brain.md §relationship facts
• Meta-rules: pattern tracking and relationship candidate detection
• Meta-rules: auto-promotion of high-confidence relationships
• Rule validation pipeline: static analysis (Fathom integration) — design-docs/03-living-brain.md:244
• Rule validation pipeline: shadow/subsumption check
• Rule validation pipeline: sandbox execution against audit log
• Rule validation pipeline: confidence scoring and promotion/rejection
• Human review queue for medium-confidence proposals
• Rule rollback and lineage tracking

Design references

• design-docs/03-living-brain.md — RKM full design (entire doc is v2)
• design-docs/05-ecosystem-roadmap.md:443-458 — checklist

Prerequisites

• v1 stable + deployed (per design assumption at 05:445)
• Sufficient audit-log history (~1000 labeled decisions per 03:238)

Closure

Epic closes when all 10 sub-items merged + integration test exercises full RKM loop (assert facts → meta-rule detects pattern → validation pipeline → human review → promotion → rollback).

Priority

P2 — v2 work, prerequisite-blocked on v1 stability.
