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.

Ben's style rule: no em-dash character in copy, docs, or code comments
(it reads as an AI tell), and the repo is going public. Replaced the
em-dashes in code comments and English UI strings with commas, colons,
or periods, whichever reads best. User-facing strings were hand-tuned
for natural punctuation rather than a blanket comma.
Preserved the lone "no data" glyph placeholders (a standalone dash used
as a not-available indicator in status displays); those are a design
element, not prose.
Regenerated app_localizations*.dart from app_en.arb (the English
fallback for untranslated keys propagates to every locale's generated
file). Non-English ARB translations left untouched.

The cache-bust helps federated catalogs on normal servers but does NOT defeat
raw.githubusercontent's CDN (ignores query + no-cache; ~5min TTL, verified).
Comment no longer overclaims. Known issue tracked in #452.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
raw.githubusercontent sits behind a CDN with a multi-minute TTL; a catalog edit
followed by a quick re-import returned the OLD profile (reported: a removed
region still showing as a change). Append a unique query param + no-cache
headers so every catalog/profile fetch is fresh.

Device-agnostic write enumerator (config_profile_writes.dart): a profile ->
ordered flat writes + per-broker field maps. Skips null/empty (never clobbers),
skips jwt_token (live-minted), holds enabled out for last-write, flags the
danger set (username/password/jwt_owner/jwt_email + wifi.pwd) for #406's gate.
Observer executor (observer_apply_service.dart): flats via setFlat, brokers via
the existing saveBroker (disable-first, fields, enabled LAST, stop-on-error
partial-safe #80); reads current enabled to preserve it when a profile omits it.
Result labels name keys/slots only, never values (no secret leak).
8 enumerator tests. Executor is thin orchestration over the tested service;
end-to-end covered by #408 hardware.

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 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.

Reactions sent from MeshCore One arrived as junk text: an emoji line
followed by an 8-character token such as "dyps6yf0". Those tokens are
Crockford Base32 target-message hashes, the second line of a two-line
reaction payload we did not recognise.
Receive-side only. Offband keeps sending its own r:hhhh:ii format; their
client already parses ours, so nothing about what we transmit changes.
Wire format (confirmed against a live capture, see #378):
channel: {emoji}@[{targetSender}]\n{hash}
direct: {emoji}\n{hash}
hash: sha256(body utf8 + timestamp uint32 LE seconds)[0:5],
Crockford Base32, 8 chars, lowercase
The body is hashed without the channel "SenderName: " prefix, which is
why the sender travels in @[...] instead.
- crockford_base32.dart: encode and normalise, 12-bit accumulator so the
web target's 32-bit bitwise ops cannot truncate a 40-bit value
- pocketmesh_reaction.dart: hash and a parser mirroring the reference
implementation, with a conservative leading-emoji check so a real
message is never swallowed
- reaction_helper.dart: ReactionInfo carries a dialect; applyReaction
picks the matching hash and, for the channel form, requires an exact
sender-name match (a node name can carry emoji and variation
selectors)
- pending_reactions.dart: a reaction arriving before its target is held
and retried rather than silently dropped, bounded at 50 entries with a
15 minute TTL and a warn-level log on expiry (closes the silent-drop
path in #382)
- the channel dedup key now includes the reacting sender, so two people
sending the same emoji no longer collapse into one
- notification tray summarises the foreign format as a reaction instead
of showing the raw token
Known limitation: on channels with Smaz or Cyr2Lat enabled the wire text
differs from the text we store, so a hash computed by another client
will not match. Flagged for a decision rather than worked around.
Epic #376. Fast-follow #383 adds reactor identity.

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.

#363 pins the DB to one directory and migrates ONE prior store in, but a user
who ran differently-built copies can have data split across several stores.
On startup (native only, after the prefs->drift migration) this discovers
every store on the machine and unions its bulk blobs (messages by id, contacts
by public key) into the current one, so nothing shows as a gap. Sources are
read-only and never deleted.
Not a one-shot: instead of a permanent flag it tracks each store's signature
(mtime+size), so a store that a stray older build later creates or grows is
re-merged rather than stranded. A store over a 200 MB guard, or one that
cannot be read, is skipped and NOT recorded as done, so it retries later.
Identity dedup is key-order independent. sqlite3 (dart:ffi) stays out of the
web build via a conditional import.

Three findings from the adversarial review (standards#145), all real, all
fixed:
- Move-then-close inside the 400ms debounce lost the final position. The
service now setPreventClose(true) and saves on onWindowClose before
destroying the window, so the closing frame is always persisted.
- _isReachable mixed a display's visible ORIGIN with its total SIZE when
visibleSize was null, producing a rect offset from the real area. It now
uses the visible pair when both are known, else the total pair. Negative
visiblePosition (a monitor left of/above primary) is handled by intersect().
- The window listener and debounce timer are now released in onWindowClose.
flutter analyze clean, dart format clean, 509 tests pass.
The stock Flutter desktop runner never saved the window frame, so the window
always reopened at a default position and size (#349). Adds
WindowGeometryService (window_manager + screen_retriever): it saves the frame
on move/resize, debounced, and restores it on launch.
Restore is clamped against the connected displays. A window last placed on a
monitor that is now unplugged must not reopen off-screen where it cannot be
grabbed; if the saved frame does not overlap any display by at least 80px on
both axes it is discarded and the window opens at the default. A too-small or
undecodable saved value also falls through to the default (logged, not
swallowed).
Gated on PlatformInfo.isDesktop, so it is a no-op on mobile and web. Scoped
past just Windows deliberately: window_manager is desktop-only and the same gap
exists on Linux/macOS, so all three get the fix rather than Windows needing an
extra guard.
Known limitation, not addressed here: without a native runner change to start
the window hidden, restore repositions AFTER the window is shown, so there can
be a brief flash at the default position before it jumps to the saved frame.
Eliminating that needs a windows/runner edit; flagged for the owner to judge
during hardware test.
flutter analyze clean, dart format clean, tests pass. Windows-run verification
is the owner's (geometry is a real-desktop behaviour).
Owner hardware test on an S25 FE and Windows turned up five issues. Three of
them shared one root cause.
**Map: always show names.** New mapAlwaysShowNames setting, toggled from the
map panel. Names were shown only past zoom 14; the override wins at any zoom.
Evaluated at build rather than only on camera movement, so flipping the switch
repaints immediately instead of waiting for the next pan.
**Panel footer on every screen.** Disconnect and Settings now also appear
inside a channel. The footer is app-level, so it belongs anywhere the panel
is, not just the primary views.
**Back button (three reported symptoms, one cause).** Channels, Contacts and
Map each wrapped themselves in `PopScope(canPop: !isConnected)`, so while
connected the system back press was swallowed whole. That explains all three:
an open drawer would not close, Android would not background the app, and on
Windows the pinned layout has no Scaffold drawer, so the app bar auto-implied
a back arrow whose press PopScope then discarded - a button that visibly did
nothing.
AppShell now owns back handling for every screen that uses it, in order:
close an open drawer, else pop the route (a pushed chat returns to its list),
else hand back to the OS via SystemNavigator.pop() so Android returns to the
home screen or the previous app. The three per-screen PopScope wrappers are
removed. AppShell becomes stateful to hold the scaffold key this needs.
flutter analyze clean, dart format clean, 469 tests pass. Not yet re-tested on
hardware.
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.

Epic A of the navigation redesign (#102). Adds AppShell, which owns the
bottom QuickSwitchBar that Channels, Contacts, Map and Line-of-Sight each
mounted separately, plus a left nav drawer: a transient slide-out on narrow
layouts and a dockable panel that can be pinned open at >= 720px.
- New lib/widgets/app_shell.dart. Reuses the 720px breakpoint established by
settings_shell.dart. Pinned wide lays the panel out beside the body (Row),
unpinned uses a standard Scaffold drawer so the hamburger is injected
automatically; automaticallyImplyLeading:false was removed from the four
app bars to allow that.
- Pin state persists via UiViewStateService.navDrawerPinned. The load is
placed before the channel-sort block in initialize(), which returns early
and would otherwise skip it.
- drawerContent is an empty slot here; the channel list fills it in Epic B
(#289).
Per owner decisions on #102 (2026-07-16): the bottom bar stays a bottom bar
at every width (no left rail), and the drawer carries no view switcher, since
the bottom bar owns view switching.
flutter analyze clean, dart format applied. Not yet run on hardware.
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).

Adds ChannelNotifyMode { all, mentionsOnly, off } and a channelNotifyModes
map keyed by PSK identity via AppSettings.channelNotifyKey, mirroring the
psk_ marker scheme ChannelMessageStore uses for history (#194). Keying by
PSK rather than display name means the setting survives a channel rename
and does not bleed across a slot reassignment (#193).
Legacy muted_channels stays readable and keeps being written:
AppSettingsService.channelNotifyMode falls back to it by name so a channel
muted before this feature still reports off, and setChannelNotifyMode keeps
it in sync so rolling back to a build without notify modes still honours an
Off channel. Name cannot be resolved to a PSK at the data layer, so the
migration is a read-through fallback rather than an upfront pass.
The notification gate and Channels UI still use the legacy isChannelMuted
path; #261 and #262 switch them over.

The DTR low→high pulse in the desktop USB open path resets ESP32 USB-Serial/JTAG
chips (VID 303A: C6/H2/S3-HWCDC) into ROM download mode mid-handshake, wedging
the device until a physical reset. The pulse exists for nRF52 (VID 239A)
reconnect-after-unclean-disconnect, so it can't just be removed.
connect() now recovers the port's USB VID from the flserial enumeration
(hardware_id) and gates the pulse: 239A keeps the DTR low→high pulse; 303A and
any unknown/unparseable VID open with DTR asserted and no pulse. VID lookup is
enumeration-only (never opens the port). New usb_vid helper parses both flserial
hardware_id formats (Windows VID_XXXX and macOS/Linux VID:PID=xxxx:xxxx), unit
tested. Build of epic #245.
BlockService gains a firmwareSync sink (fired on real block/unblock/promote) and
importKeys (pull side, no echo). Connector sets the sink in initialize, pushes
ADD/REMOVE via 0xC2 when supportsOffbandBlock, and on device-info (caps landed)
pulls BLOCK_LIST. On dump completion: UNION — import node keys missing locally
(no echo), push local keys the node lacks; never remove (only explicit unblock
sends REMOVE). Non-Offband radios skip all of it (app-local only).

getBrokers logs request-sent, header count, and completed-with-N-brokers-in-Xms or failed-after-Xms (frames + expected count) via FileLogService. A tester Share-logs capture then shows in plain text whether the broker pool load succeeds, stalls, or times out - which the raw BLE frames cannot reveal. Behaviour unchanged (parse-once refactor; all 13 service tests green).

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.

Always-on file logging so users/support can retrieve a log without enabling
anything in the UI. No-op on web (no filesystem).
- FileLogWriter: rotating file writer (size cap + max files), single + batch
writes, unit-tested against a real temp dir.
- FileLogService: singleton initialised in main(); resolves
getApplicationSupportDirectory()/logs, queues lines, periodic 2s batched
flush, bounded queue, never crashes the app on an IO error.
- AppDebugLogService.log + BleDebugLogService.logFrame write every entry to the
file (app logs always, independent of the in-app viewer's enable gate).
Location per the #97 decision: standard support dir on all platforms (Windows
%APPDATA%\app.offband.meshcore\logs). Still TODO before recompile: access UI
("Open logs folder" on desktop / "Share logs" on mobile).

A firmware build can ACK a broker enable/disable as success without applying it
(HV4; meshcore-firmware#179). The quick toggle and the editor save previously
trusted the ACK and showed a success snackbar, so an ack-but-no-op looked like
it worked.
Both paths now SET, wait a short settle, re-read the slot, and report what the
device ACTUALLY did:
- applied -> confirm
- notApplied -> warn "possible firmware issue"; the editor stays and re-seeds to
the device's true state instead of popping a false success
- unverified -> re-read failed (e.g. an enable that rebooted the device)
Every device is treated identically: the UI reflects the re-read, never assuming
a change took that the device didn't confirm.
- BrokerConfig.classifyApply pure classifier + BrokerApplyOutcome (unit-tested)
- ObserverConfigService.applySettleDelay
- wired into mqtt_brokers_screen quick toggle + broker_editor_screen save

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.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
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.

Greens A2's adversarial tests, fixing the Gemini findings:
- BLOCKER #1 (race): a chain-lock (_serialized) serializes every transport
round-trip, so overlapping refresh()/setFlat() can no longer cross responses
(firmware has no request id; responses correlate by order).
- MINOR #6 (secret leak): error messages redact secret key names
(wifi.pwd / *.password / *.pwd -> "<secret>").

- screens/settings/observer_settings_view.dart: staged-save pane for WiFi
(ssid/pwd/enabled), MQTT region (iata/status_interval), display
(always_on/rotation 0|180), with Save (changed keys only) + Refresh +
stale/error banners; the broker pool renders read-only (enable/clear await
the firmware F-task).
- settings_screen.dart: register the Observer category, gated on
ObserverConfigService.supported (re-evaluated as the connector's offband_caps
flips on connect/disconnect).
- connector/meshcore_connector.dart: parse the offband_caps byte (device-info
byte 82, after path_hash_mode) + expose offbandCaps.

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.
