Fixes the confirmed downlink/uplink defects from the PR #1384 review +
Codex findings:
- Downlink age + #g gate (Codex P2 / review #1): rebroadcastRelayEvent
now drops events outside the same freshness window receivers enforce
and whose #g tag mismatches the carrier geohash, BEFORE spending any
budget — so a 1h/200-event channel-resubscribe backfill no longer
burns the 30/min BLE budget on events every receiver drops.
- Rate-limit + dedup before Schnorr (review #2): handleUplinkDeposit now
runs cheap structural checks + carried-ID dedup + rate-token consume
before isValidSignature(), so a replay flood is bounded by cheap work
instead of unbounded main-actor verifies.
- Quota-dropped deposits not rendered (review #3): enqueueUplink reports
acceptance and injectInbound only fires for events actually
published/queued, ending the local-timeline divergence.
- Drain timer + mark-after-send (Codex P2 / review #4): a burst beyond
budget now arms a timer to drain when the window frees; rebroadcast
IDs are marked only after an event is actually sent, so overflow-
dropped events stay retryable.
- Symmetric publish path (review #5): the gateway publish closure now
refuses when no geo relay is known, matching the local send path
instead of publishing dead traffic to default relays.
- Loop-rule doc (review #7): softened to reflect that rule 3 is a
call-site convention with unit-tested backstops; added tests for the
publishedEventIDs backstop, downlink freshness/mismatch, drain timer,
and quota-drop non-injection.

An opt-in "internet gateway" toggle lets one connected phone bridge the
local geohash channel for mesh-only peers: signed kind-20000 events ride
a new nostrCarrier (0x28) packet — directed to the gateway for uplink,
broadcast with TTL for downlink — with Schnorr verification at every
hop, CourierStore-style quotas, and explicit loop-prevention rules.
- BitFoundation: MessageType.nostrCarrier = 0x28
- NostrCarrierPacket: 2-byte-length TLV codec (direction, geohash,
signed event JSON), 16 KiB cap, tolerant decoder
- GatewayService: closure-injected policy layer — verify gates (sig,
kind, #g tag, age, size), uplink quotas (10/min/depositor rate limit,
offline queue of 20 total / 5 per depositor, drop-oldest, flush on
reconnect), downlink budget (30/min, bounded drop-oldest backlog),
bounded loop-prevention ID sets
- BLEService: runtime capability bits (advertise .gateway only while
the toggle is on, re-announce on change), signed directed uplink
sends, carrier ingress with depositor signature verification
- Mesh-only senders uplink automatically from sendGeohash when no relay
is connected and a reachable peer advertises .gateway; once-per-
channel "sent via mesh gateway" notice
- UI: gateway toggle beside the Tor toggle, globe header indicator,
VoiceOver labels, xcstrings entries
