Tier 3 of a protest-hardening review. The BLE mesh is already properly
fenced off from network reachability and needs nothing here; every gap is
on the internet side, or in how someone gets a build they can trust.
Say when Tor is blocked. The bootstrap poll loop simply ended at its
75-second deadline, leaving isStarting true with no further state, so a
network that blocks Tor was indistinguishable from a slow one and the UI
said "starting tor…" indefinitely. TorManager now exposes
bootstrapDidStall and posts .TorBootstrapDidStall, and the app reports
that mesh messaging still works while internet delivery is paused. It is
cleared on each new start or restart, so a later attempt can report again.
Let relays be added by hand. The four built-in relays are well-known
clearnet hostnames, which is four names for a censor to block and no
recourse short of a new build. NostrRelaySettings persists up to eight
additional relays, normalized, .onion accepted, with a settings editor.
They join the same target set as the built-ins and are subject to the
same activation policy. Removal reconciles against the previous set:
the teardown path iterates the current targets, so without that a removed
relay's socket and queued sends would linger — covered by a test that
fails without it. The merged list is cached rather than recomputed,
because allowedRelayList consults it once per candidate URL and would
otherwise read UserDefaults inside that loop.
Stop stranding people who denied location. The activation gate required
location permission or a mutual favorite, but teleporting into a geohash
requires neither, so someone with no permission and no favorites could
sit in a channel that never connected while Tor and the relays stayed
suppressed and nothing said why. Being in a location channel is now a
third arm of the gate, in both the activation service and the relay
manager's copy of the policy, and leaving the channel closes it again.
Stop burning the Tor timeout when Tor is off. GeoRelayDirectory awaited
Tor readiness unconditionally, but with the preference off TorManager has
been shut down, so every refresh spent the full bootstrap deadline and the
directory froze on its cached copy. It now keys on the preference, not on
live readiness: Tor wanted but unavailable must still skip the fetch
rather than fall back to clearnet.
Say what turning Tor off costs. The toggle's copy described it as
hiding your IP "for location channels", understating both scope and
consequence. It now names private messages too, and while the toggle is
off the settings screen states that every relay can see the device IP.
Make builds verifiable. There was no release verification of any kind:
no signatures, no checksums, no documented procedure. Post-takedown that
is the acute gap, because mirrors appear and people install whatever they
can find during a shutdown. source-manifest.yml publishes a per-tag
SHA-256 manifest with a provenance attestation, self-checking before it
publishes, and docs/VERIFYING-A-BUILD.md explains how to verify source and
states plainly that compiled builds from anywhere but the App Store cannot
be verified. It also records the gaps honestly: no published signing key,
no reproducible build, no non-GitHub mirror.
docs/TOR-INTEGRATION.md was substantially stale — it documented a
torrc, SOCKSPort and ControlPort that the in-process Arti client does not
use, and claimed there are no user-visible settings — so it is rewritten,
including the deferred gap below.
Deferred: no Tor bridges or pluggable transports. arti-client is built
without pt-client or bridge-client and bootstraps from stock config, so
in a country that blocks Tor outright there is still no circumvention
path — only a clear report that there isn't. Closing it needs the Rust
features, bridge config through the FFI, and an xcframework rebuild under
the pinned toolchain with a provenance update, which is its own change.

Split-out safe half of #1437 (the kind-1402 wire migration stays held for Android coordination). Docs (README/WHITEPAPER/PRIVACY_POLICY/privacy-assessment) now describe the actual proprietary DM construction — kind 1059 gift wrap carrying XChaCha20-Poly1305 with a 24-byte nonce, base64url v2: framing, and an HKDF that borrows the nip44-v2 info label but is not the NIP-44 key schedule — instead of claiming NIP-17/44/59.
Hardens the existing legacy inbound path: 64 KiB ciphertext cap before decode (~46x the largest producible legacy envelope), outer kind/recipient-tag/signature binding, tagless kind-13 seal binding, unsigned kind-14 inner binding, inner tags restricted to the two shapes deployed clients emit (verified against every historical iOS release and a fixture frozen from Android production), SecRandomCopyBytes failure now throws, non-UTF-8 plaintext now throws instead of returning empty. Adds frozen cross-platform fixtures with hash-pinned generators; interop-reviewed with no rejection surface for deployed clients.
Raises the file-local waitUntil default from 1s to 10s (returns early on success, so zero cost on healthy runs) and fixes a latent race in the observers test: it waited on the fetch-probe request count, which increments before handleFetchSuccess settles isFetching/lastFetchAt on the MainActor, so the next trigger notification posted into that gap was silently swallowed by the guard. Now waits on the .geoRelayDirectoryDidRefresh notification posted at the end of the synchronous success handler. Negative checks assert against captured baselines. No assertion weakened; 15/15 x 9 local runs including under 2x-ncpu CPU load.
Replaces the scheduled workflow that pushed upstream georelay CSV directly to main unreviewed with a validator-backed automation that resolves an immutable upstream commit, validates against the reviewed baseline, and opens a non-auto-merged PR (or tracking issue) instead of writing to main. Adds a mirrored strict client-side validator in GeoRelayDirectory (all-or-nothing, size/row/host/coord caps, streamed 512KiB cap, >=50% baseline overlap) that fails safe to last-known-good, and retargets runtime refresh to bitchat's reviewed copy.
* NIP-13 proof-of-work for geohash channels: mine on send, relax rate limits for PoW senders
Outgoing kind-20000 geohash messages mine a NIP-13 nonce tag (8 leading
zero bits, ~256 hashes, typically <1 ms) off the main actor before
signing. Mining is hard-capped at 2 s and cancellable (newer send or
channel switch): on cap/cancel the committed target steps down so the
message still ships promptly with an honest commitment - sending is
never blocked and nothing is dropped. The hot loop serializes the
canonical event once and rewrites only the fixed-width nonce bytes.
Inbound kind-20000 events are scored per NIP-13 commitment semantics
(committed target counts; the ID must actually meet it, extra work
earns nothing) and never hard-rejected: validated PoW >= 8 bits skips
the per-sender rate-limit bucket while the per-content flood bucket
still applies, so old non-mining clients keep working under today's
strict limits while bulk spam gets expensive.
Presence heartbeats (kind 20001), kind-1 notes, and DMs are unchanged;
no UI beyond a pow= field in an existing sampled debug log.
Reimplemented from scratch rather than cherry-picking the stale
feature/pow-geohash-mining-ui branch (unbounded loop, hard receive
filtering, mining UI, XCTest, force unwraps).

* Geohash: serialize PoW sends so order matches send order
Two location-channel sends back-to-back only cancelled the previous
mining task and started a new one. Cancellation merely *expedites* NIP-13
mining (the target is polled and steps down; it never aborts the send),
so the cancelled task still appended + relayed once mining returned. Both
tasks ran concurrently and the second (shorter to mine) could finish
first, reordering messages in the timeline and on relays.
Chain the mining tasks: each geohash send captures the previous send's
task, cancels it (to expedite, so delays never stack), and awaits its
completion before it echoes and relays. Order is now always send order.
The >2s mining cap is preserved: cancellation expedites the awaited task,
so a send is never blocked beyond NostrPoW.miningTimeCap.
Test: two rapid sends where the first mines longer (larger content) still
land in send order for both the local echo and the relayed events.

* Make location notes robust: durable relay subscriptions, failure decay, auto-recovery
Location notes (and geohash chat / DMs) intermittently stopped showing
events because the Nostr relay layer lost subscriptions and blacklisted
relays:
- Replay active subscriptions on every relay (re)connect. Relays drop
REQs with the socket; previously a drop silently killed the
subscription on that relay for the rest of the session. Durable
subscription intent now also survives disconnect()/resetAllConnections
(background -> foreground).
- Keep failed REQ sends queued instead of dropping them.
- Raise the EOSE fallback from a fixed 2s Timer to a 10s injected
schedule (Tor needs more than 2s), and settle EOSE trackers when a
relay disconnects before answering so initial load doesn't stall.
- Decay "permanently failed" relay markings after a 10-minute cooldown;
previously ~9 minutes of outage (or one DNS hiccup) excluded a relay
until app restart, with nothing resetting it on macOS.
- Make geo relay selection deterministic (distance, then host) so
publishers and subscribers with the same directory agree on relays.
- Post .geoRelayDirectoryDidRefresh after a directory fetch and let
LocationNotesManager auto-resubscribe out of the "no relays" state
instead of requiring a manual retry.

* Guard subscription activation on connection identity
A REQ send completion from a dead socket could land after
handleDisconnection cleared the relay's subscriptions and re-mark the
subscription active, making the next connection skip the durable replay
and leave that relay silent. Only mark a subscription active if the
completing socket is still the relay's live connection.
Regression test defers send completions in the mock so the stale
completion deterministically interleaves between disconnect and
reconnect.
Addresses Codex review on #1333.
