description	Capture one compounding repo-technical learning while a solved problem is still fresh. Use when: after a bug fix, diagnosis, delivery, review, or incident reveals a reusable pattern worth adding to `docs/solutions/`. Trigger: /compound, /capture-learning, /learning.

/compound

Capture the learning, not the whole story.

Contract

• One solved problem -> one learning.
• Corpus: docs/solutions/<category>/<slug>.md; schema: primitives/shared/references/learnings.md.
• Overlap first: rg -n --glob '*.md' '^(title|tags|applies_when):|<module>|<failure-mode>' docs/solutions.
• If an existing learning covers it, update that file only when the fresh evidence contradicts or sharpens it. Otherwise do not add a near-duplicate.
• If new, use grep-ready frontmatter: title, tags, module, problem_type, applies_when, severity, date.
• Cite checkable evidence: repo@SHA, PR, command, route, and file:line where possible. Session notes may provide context; they are not the anchor.
• Pattern docs are promoted from multiple learnings. Never author a broad doctrine page cold from one bug.

Write Discipline

Present evidence wins at read. Coherence-neighborhood at write: refresh only nearby learnings likely to conflict. On contradiction, scope the refresh to the smallest corpus slice that can be wrong.

Completion Gate

See primitives/shared/AGENTS.md (Prove) for the shared core. /compound adds: the path written or updated, the overlap query used, the evidence anchor, and 3-6 retrieval terms future agents should grep.
