Adversarial review of the storm/deadlock PR surfaced four issues:
- Offline blackhole (must-fix): a deposit made while relays were down
persisted its dedup key even though the drop only sat in the in-memory
pending queue — app killed before reconnect meant the relaunch lost the
drop but the persisted key blocked every re-deposit for 24h. The
persisted snapshot now excludes keys still pending; they become durable
only when flushPendingDrops actually publishes them.
- Gateway handoff: seen-event IDs were consumed before the deliverToPeer
handoff; a failed handoff (peer walked away) permanently dropped the
event for a single-gateway island. deliverToPeer now reports whether
the handoff was attempted, and a failure releases the seen slot so a
relaunch or backlog redelivery retries.
- Restore-path logs: central/peripheral-restore captures logged the init
sentinel bgRemaining=∞. The cache is now seeded in init's main-thread
branch and restore captures route through the sampler, which refreshes
the cached budget before logging.
- Persist cost: the dedup record was a full JSON encode + atomic write on
the main actor per mutation (once per event during a backlog re-fetch).
Writes now coalesce behind a 1s window, flushed immediately on
background/terminate; panic wipe stays immediate.
