+Use this index for second-order workflow lessons.

+
+## When To Reflect
+
+Create a reflection only when work reveals a reusable lesson: skipped gates, repeated mistakes, durable debugging patterns, ineffective plans, human corrections, or candidates for new scripts or skills.
+
+Routine task completion belongs in `30-worklog/task-history.md`.
