Session 737 lost its cost values when status changed to done/ended (cost shown while active, zeroed on completion)

Operator (Mike) report: session /sessions/737/segments had been showing a cost while active; when it transitioned to status=done/ended, the cost values were lost (dropped to 0/null). Suspect the status→ended lifecycle transition (or a re-ingest triggered by it) overwrites/recomputes/zeroes the session cost aggregates — e.g. a full-model save on status change overwriting cost fields, or a re-ingest that drops session_usage rows so the aggregate recomputes to 0. Needs: confirm session 737's current cost aggregate fields vs its session_usage rows once artisan boot is restored (currently broken by the in-flight Briefs\Show route). flower-ops triaging via code path now.
