Lesson Propose

The worker proposes lessons; it never promotes them. Promotion (candidate → control/approved_lessons/ or rules.md) is a human git action, not a tool the worker can call.

When to use

• Task wrap-up, postmortem, or when a correction/drift note should outlive this task.

Procedure

1. Read state/tasks/<task_id>/correction_journal.md and any session observations.
2. For each keeper, write a candidate into state/tasks/<task_id>/candidate_lessons.md, tagged with a target tier:
   • working-only — relevant to this task only; stays in state/.
   • approved-lesson-candidate — recurring; propose into control/approved_lessons/.
   • policy-candidate — stable, cross-task; propose into control/rules.md.
   • gate-candidate — binary, machine-checkable; a human may translate it into an agent-completion-gate check (this skill does NOT touch the gate).
3. Each candidate carries: the lesson, evidence (cite the journal entry), applies_when, and not_authoritative_until_reviewed: true.
4. Leave everything in candidate_lessons.md (pending). Do not move anything into control/ yourself.
