description: Preserve the durable lessons from completed Task work.
action_style: procedural
---
Record only learnings that should change future behavior.
Read the Task design, review, and incident analysis when present. Confirm that
the lesson is already executable in the gated code, tests, nearby documentation,
or a transparent `.lf/` adaptation. Do not change material work after the gate;
if enforcement is missing, report the gap so the Task returns to its loop.
When the seed names a live Wave and a durable operating insight remains, record
it with `lf memory add`; never edit `wave/<name>/MEMORY.md` directly. A stopped
Wave or unavailable memory surface must not block shipping—record the useful
lesson in the PR instead.
Leave no generic retrospective. State the invariant learned, the evidence for
it, and where the repository now enforces it.
