Development queue recovery for stranded slot indices (Issue #731)
2026-04-05
- Fixed tick queue processing so build/research rows with invalid `slotIndex` values are repaired to a valid slot instead of getting orphaned.
- Repaired rows are now processed in the same tick, so stranded pending development can promote and progress normally.
- If an invalid-row was marked `ACTIVE`, it is safely demoted back to `PENDING` before standard slot arbitration.
