Keep reverse history and stored SHM layout aligned so sparse IB
frames do not expose permanent zero-time reservations.
Deats,
- omit inclusive query endpoints from SHM but retain full storage
- serialize and bound farm resets, blanks, and cancellations
- run the final null sweep after reverse retrieval completes
- require valid timestamp boundaries for synthetic gap rows
- cover the live QQQ 653-row failure and reset interleavings
