Loop Self-Improvement (Phase 9d)

Extract durable agent-facing learnings from a completed loop run. Do not update wiki (that's Phase 9c ce-compound).

When to run

• Profile has self_improvement: true (or rationale-only fallback for --repo without named profile)
• Loop completed Phases 1–8 at L2/L3
• L1 loops skip 9d → orchestrator ends 9d with NO_LEARNINGS / skip (no contract emitted)

Emit NO_LEARNINGS when:

• L1 mode
• self_improvement: false on profile
• Duplicate fingerprint with no new insight vs existing pattern/quirk
• No durable agent-facing learning from the run

Inputs

• Active profile YAML (pattern_doc, known_quirks, repos)
• Active --repo path
• JIRA key, PR URL, test names, failure router signals from the run
• docs/loop-learnings/README.md index (fingerprint run counts)

Scope routing

Scope	Min runs	Contract mode	Target
Single repo	1	loop_learning	pattern_doc append + upsert_known_quirk
context_skill	2+ (1 if Phase 8 AC→test map)	promotion_proposal	e.g. cell-health-mvp/SKILL.md
Profile family	2+	promotion_proposal	springboot-default.yaml
Spring Boot all	5+	promotion_proposal	java-springboot-standards.mdc
Ops	1	loop_learning	ops-incident-patterns.md
PR review	2+	promotion_proposal	pr-code-review.mdc
No profile	n/a	loop_learning	rationale only (targets: [])

Output (TOON contract)

Emit one shared <UTC-ts> = YYYYMMDDTHHMMSSZ per run.

1. Rationale: docs/loop-learnings/by-repo/<repo>/<JIRA-KEY>-<UTC-ts>.md
2. Learning contract: docs/loop-learnings/contracts/<repo>/<JIRA-KEY>-<UTC-ts>-learning.json
3. Promotion (if threshold met): docs/loop-learnings/pending-promotion/<scope>/<JIRA-KEY>-<UTC-ts>-promotion.json
