Children of #471 (parent stays open for AAB hardware validation, #507).
The block list was one global unscoped list on the phone, unioned onto
every radio on connect. A stale block for one of the owner's own radios
therefore rode onto every fresh/erased radio, and clearing a radio never
stuck: any other radio still holding it re-seeded the global list on
connect, which re-pushed it back.
- #505 block_store.dart: scope keys/names by connected device key (like
the app's other stores); dropLegacyGlobal() deletes the legacy
block_keys_v1/block_names_v1 (drop-and-start-fresh, owner-approved).
No global list.
- #505 block_service.dart: load() drops the legacy global and starts
empty; loadForDevice(deviceKey) swaps the in-memory set per radio and
runs the #250 self-heal. All mutating ops serialized through a Future
chain so loadForDevice and importKeys (different connector frame
handlers, both unawaited) cannot interleave and wipe each other.
- #506 meshcore_connector.dart: the device-key hook loads the connected
radio's list, so the offload union reconciles within that one radio.
Existing radio-side firmware blocks left untouched (no auto-CLEAR on
migration, owner-approved). Tests: per-radio isolation, clear-sticks
across reconnect, legacy-drop, disconnect-clears, load/import race.

A transient upstream 503 (e.g. Hugging Face) hard-failed the model download and
surfaced it as an error (#229). The download requests (HEAD, single GET, range
GET) now go through sendModelDownloadWithRetry: 5xx/429 responses and network
exceptions retry with bounded exponential backoff (1..30s, <=5 attempts, honors
Retry-After, cancellable); terminal 4xx (e.g. 404) fail immediately. The retry
logic is a pure injectable top-level function, unit-tested (503-then-200,
persistent-503, 404-no-retry, network-exception, cancel).
Manual retry after a sustained failure is the existing "Download model" button
(re-invokes the download); no new UI added. Build of epic #422.
Follow-up to #457. Swept the em-dash character (U+2014) out of the test
tree (test descriptions and comments) and cleaned 8 em-dashes that
landed in lib comments via the #456 refactor after #457 merged, so the
tree is back to zero. Same rules: replaced with commas/colons/periods,
preserved the lone "no data" glyph placeholders, left non-English ARB
untouched.

Profile is now a container of capability-scoped sections (schema_version 2):
- wifi (WifiConfig) — any wifi device
- mqtt (MqttSection = region + status_interval + brokers) — observer capability
so MQTT is defined once and shared by observer / observer-repeater /
observer-companion, never redone per device. Future radio/repeater/companion/
display sections slot in alongside.
Parser reads the sectioned YAML and rejects the old flat v1 layout with a clear
message. Enumerator reads from sections but emits the SAME firmware keys, so
apply/diff/screens are unchanged. 45 config-profile tests updated + green.

A max-length DM built a 170-byte frame but this BLE link only writes
ATT_MTU-3 (=169) bytes, so writeCharacteristic threw. The DM path swallowed
the throw and never resolved the message, leaving it "active" forever and
silently blocking every later DM to that contact until force-stop+reconnect.
- Size: maxContact/ChannelMessageBytes take an MTU-aware frame budget
(BLE = mtuNow-3, USB/TCP = maxFrameSize); composers pass
connector.effectiveMaxFrameSize. The channel cap now also subtracts the
"Name: " prefix so a small-MTU link can't overflow.
- DM wedge: _sendMessageDirect propagates the failure and the retry callback
is awaited, so a failed send marks the message failed and drains the
per-contact queue. Added a RESP_CODE_SENT safety timeout.
- Channel wedge: sendChannelMessage clears the stuck queue id and marks the
message failed on a failed write.
- Tests: MTU-aware caps + failed-send-does-not-wedge regression.

The 172->176 ceiling raise made the existing "drops oversized frames and
resyncs" test's 173-byte frame a valid length, so it buffered instead of
dropping (it was red). Derive the over-max length from the ceiling so it stays
a genuine oversized frame and still exercises drop-and-resync, confirming the
higher ceiling doesn't weaken corrupt-frame recovery. Full suite: 643 green.

The frame decoder capped companion frames at 172, but the firmware's real
MAX_FRAME_SIZE is 176 (BaseSerialInterface.h, "+4 for transport codes").
Full-size caplog CHUNK frames (176 B) were silently rejected; only the final
sub-172 partial chunk survived, so a download reassembled just the last chunk
(e.g. "received 95 of 5141"). Caplog is the first feature to use full frames,
so nothing exposed this before.
- usb_serial_frame_codec.dart: usbSerialMaxPayloadLength 172 -> 176.
- serial_capture_screen.dart: erase-on-start (Start / Start&Reboot) for a clean
session ("didn't start at 0").
- 3 decoder regression tests; 113 tests total green; analyze clean.
Root cause confirmed with firmware (TopazHill): firmware streams the full
buffer correctly (wire trace 5175/5175); the client decoder dropped oversized
chunks. My earlier firmware-ring hypothesis was wrong.

When the database can't open (e.g. the native sqlite library fails to load),
every read/write silently failed and the app opened to an empty, normal-looking
screen — the user thinks their history was wiped (SAFELANE §6 violation).
Probe the storage layer in main() before any store reads
(BlobStore.verifyReadWrite). On failure, a StorageHealthService one-way latch
records it, and a persistent, non-dismissable banner is shown above the whole
app: history is not lost, storage is unavailable, messages are NOT being saved,
restart after fixing. Cross-platform (probe goes through drift, covers web too).
Tests: service state/latch + banner show/hide widget test. Gemini-reviewed.

formatNotificationText used GifHelper.parseGif (Giphy only) while the chat
renders via resolveGifUrl (Giphy + allowlisted Tenor CDN). An allowlisted
Tenor GIF therefore rendered inline but still dumped a raw URL into the
notification tray.
Point both at resolveGifUrl so the tray summarises exactly the set the chat
displays. Off-allowlist URLs still pass through as plain text, pinned by test.
This is the same duplicate-detection drift that caused #284; closing it at the
source rather than shipping a known inconsistency.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Notifications summarised a GIF as "Sent a GIF" using their own hand-rolled
`^g:[A-Za-z0-9_-]+$` regex rather than GifHelper. #282 changed the payload to
`https://giphy.com/gifs/<id>`, which that regex does not match, so GIF
notifications regressed to dumping the raw URL into the tray.
Detection now goes through `GifHelper.parseGif`, matching how the adjacent
reaction case already delegates to ReactionHelper. That restores the summary
and covers every form the app can send, including replies (`@[Name] ` +
payload), which the old regex never matched even for legacy `g:<id>`.
Verified no other hand-rolled `^g:`/`^m:`/`^s:`/`^r:` payload regexes remain
outside their owning helpers, so this class of drift is closed.

Blocking yourself silently hid your own traffic with no visible cause,
and because blocks are offloaded to the radio it was pushed there and
could be pulled back by the connect-time union.
BlockService gains a selfKeyHex, injected by the connector when the self
key is learned and cleared on disconnect. Every add path refuses it
(block, importKeys, maybePromote) — importKeys specifically, so a
self-block already on the radio cannot be re-imported. setSelfKey also
heals an existing self-block and pushes REMOVE, covering the case where
the union pull lands before self-info arrives. Contacts and discovery
sheets hide the Block option for your own node.
Per Gemini review: heal on an unchanged key too (an early return would
strand a self-block introduced after the key was known), and order
setSelfKey so all in-memory state settles synchronously, keeping callers
consistent even though the connector fires it unawaited.
Adds test/services/block_service_test.dart — the first coverage for
BlockService (10 tests).

The broker-pool GET put a single fixed 6s deadline on the entire paginated dump. A large pool (6+ brokers) streams field-by-field over ~8s and blew the deadline, so the client falsely reported the pool as not finished even though the device sent it all (the END terminator arrives after the client gave up). Re-arm an inactivity Timer on each received frame: a steadily-streaming dump never times out; only a genuine stall (no frame for the timeout window) fails. Adds a TDD test - a slow-but-steady dump, frames under the timeout but total far over it, must complete.

The write half of the broker editor, against RedCreek's confirmed field-at-a-time
contract. The existing 0xC0 key/value command already carries the broker keys --
no new wire codes -- so the codec comment at observer_config_client.dart:166 is
stale, not a gap.
- saveBroker(): disable a live slot first, write each changed field, write
`enabled` LAST. Stops at the first ERR/timeout and reports the failed field --
a partial save leaves the slot disabled, never live-corrupt (activation guard).
TDD: ordering + partial-failure tests.
- clearBroker(): mqtt.broker.<slot>.clear.
- getBroker(): single-slot re-GET via 14 per-field GETs (recovery / post-save
read), not the 84-frame pool dump. Password is write-only -> best-effort.
Key spellings (mqtt.broker.N.enabled / .clear, scalar field GET) are inferred
from the existing scheme; they're the one thing the joint firmware test confirms.
12/12 service tests green. UI (brokers screen + editor) next.

Three observer-delta fixes (per the #80 sync diagnosis / G2):
- A: settings screen gates the Observer category via context.select on the
supported flag, not a connector-wide context.watch -- the watch rebuilt the
whole settings screen on every sync frame, thrashing the UI thread.
- B: a flat Save re-reads only the flat settings (refresh includeBrokers:false),
never the 84-frame broker pool -- no BLE re-flood for a display toggle.
- C: the initial observer read is deferred until the device's channel/contact
sync settles, so it never competes with that sync for BLE.
TDD: B (no OCFG_BROKERS on a flat refresh) + C (refresh deferred while syncing,
fires once idle). Full observer suite green.

The G2 BLE log showed the config protocol works (GETs return values; the broker
dump starts) but the firmware's broker dump stalls without BROKERS_END, so
getBrokers() times out. The client was treating that as a TOTAL failure --
discarding the 7 flat settings it read cleanly and blanking the pane.
Now the broker pool loads independently: refresh() builds + shows the flat
config even when getBrokers fails, flags brokersUnavailable, and the pane shows
the broker section as "unavailable" instead of going stale. Flat settings stay
usable. TDD red->green; full observer suite (39) green.

Closes the 2 MINOR findings from the G1 re-review (#76):
- MINOR-A: ObserverConfigService.refresh() no longer wipes lastError / clears
stale on a PARTIAL read. A null from any getFlat is a failed read; the
snapshot is marked stale and the error kept (error-visibility).
- MINOR-B: the settings pane validates status_interval against the firmware
range (10-3600) before sending; an out-of-range value is not put on the wire
and the user is told.
TDD: both tests RED first (current sent '5'; refresh wiped the error), GREEN
after. Full observer suite (37 tests) green.

main.dart wiring verified correct (no change): the singleton MeshCoreConnector
(main.dart:38 -> field -> provided by value) is the SAME instance passed to
ObserverConfigService, so the service watches the live transport. Plain
ChangeNotifierProvider (not a proxy) is right -- the connector instance is
stable; only its state changes, which the service reads live. Lazy-safe: the
constructor has no side effects.
This test pins that contract: the service is reachable through Provider and a
mutation to the shared connector's caps flips the Observer gate (supported).

4 tests for ObserverConfigService via a fake connector (subclass override of
the 4 members the service uses -- no production change). 2 green (capability
gate, happy-path setFlat). 2 RED BY DESIGN, documenting the Gemini findings to
be fixed by S1 (#73):
- BLOCKER #1: overlapping getFlat/setFlat cross responses (single-flight is
assumed, not enforced) -- setFlat receives the GET's value, not its ACK.
- MINOR #6: a secret key name leaks into the error string
("SET wifi.pwd failed: ...").

PathHistoryService capped each contact's recentPaths at 100 but dropped any new distinct path once full, so the list froze on the first 100 ever seen and never refreshed with newer/better routes. Evict the lowest-_scorePathRecord entry to make room, keeping the strongest 100. Adds a regression test (full history evicts the weakest to admit a new path).
