EPIC: Inspectable memory and learned workflows

Programme: #1

Own explicit preferences, scoped and inspectable memory, optional adaptive patterns, and promotion of successful work into verified reusable workflow recipes.

## Child issues
- [ ] #89 MEM-01 — Explicit preferences and memory inspector
- [ ] #90 MEM-02 — Opt-in adaptive patterns and declared lenses
- [ ] #91 MEM-03 — Verified workflow recipes and procedural learning

## Cross-cutting gates
Origin, scope, confidence and expiry are visible; deletion removes future context eligibility; inferred preferences remain distinct from confirmed preferences; personalization cannot rewrite evidence; repeated success never auto-installs arbitrary scripts.

No files, tests, or entry points are named. Start by reading child issues #89, #90, and #91, then use the listed cross-cutting gates to understand the programme scope. Done means the child work addresses visible origin, scope, confidence, and expiry, safe deletion, preference separation, evidence protection, and controlled recipe promotion.
