Store-and-forward previously delivered to an out-of-range peer only if a
mutual favorite happened to be connected at send time and later met the
recipient directly, and everything except courier envelopes died with the
app process. This closes those gaps end to end:
- Persist the MessageRouter outbox to disk, sealed with a ChaChaPoly key
held only in the Keychain (no plaintext at rest); queued private
messages now survive an app kill and flush on next launch.
- Deposit retry: queued messages are re-deposited whenever a new eligible
courier connects, tracked per message so the same courier is never
double-burned, until 3 distinct couriers carry it or it expires.
- Tiered open couriering: signature-verified strangers can now carry mail
(2 envelopes/depositor into a 20-slot pool) alongside mutual favorites
(5 each); overflow evicts verified-tier mail before favorites'.
- Spray-and-wait: envelopes carry a copy budget (4, capped 8, new TLV,
wire-compatible with old clients); couriers split half their remaining
budget with each newly encountered courier so mail diffuses through a
moving crowd.
- Remote handover: a verified relayed announce now floods a copy toward
the multi-hop recipient (directed-relay treatment, 10-min per-envelope
cooldown) while the carried original stays put for a direct encounter.
- Public history: gossip-sync window for whole public messages widened
from 15 min to 6 h, matched on the receive-acceptance side, and the
message store persists to disk so devices bridge partitions and
restarts ("town crier").
- Privacy-safe local delivery counters (bare tallies, log-only) so the
store-and-forward stack is measurable on-device.
- Panic wipe now also clears the sealed outbox, gossip archive, and
counters.
- Rewrite WHITEPAPER.md to describe the app as implemented (Noise XX/X,
actual flood control, courier system, gossip sync, Nostr path); the old
document described a bloom filter, three fragment types, and a
MessageRetryService that don't exist.
1037 macOS tests pass (17 new); iOS builds.
