## Prompt

The user asked why the in-progress `piker/storage` changes were omitted
from the earlier commit plan. After receiving an inventory of unfinished
Phase 3 requirements, the user instructed the agent to complete the work.

## Response summary

Finished non-destructive, atomic NativeDB updates and integrated them
with history startup and reverse backfill. Expanded tests through two
adversarial review rounds that caught and corrected cross-client lock
blocking, stale temp indexing, discontinuous persisted indexes, startup
snapshot races, missing latest-frame persistence, notification wedges,
and mutable/truncated SHM persistence.
