The Android SDK lives in the read-only Nix store, so the Gradle build
cannot auto-install missing components. Pin everything the Flutter
Android build needs in the dev shell's composeAndroidPackages:
platforms 33-36 (app targets 36; plugins pin 34 and 35), build-tools
35.0.0 (AGP 8.11.1), NDK 28.2.13676358 (flutter.ndkVersion), and
cmake 3.22.1 (plugin native builds).
Also redirect the Android Gradle Plugin to the Nix-patched aapt2 from
the SDK via android.aapt2FromMavenOverride, written to the user-global
~/.gradle/gradle.properties on shell entry (the project's tracked
gradle.properties must not contain a machine-specific store path).
AGP's Maven-downloaded aapt2 cannot run on NixOS.
Ignore the generated frontend/android/build/ directory.

Pin the Android SDK composition (platform 36 + google_apis x86_64 system
image + emulator) via composeAndroidPackages so the emulator image is
always available and reproducible across machines. Auto-create the
"oott_api36" AVD idempotently on dev-shell entry, and add
frontend/android-emulator.sh to launch it.

The status screen was a non-scrolling Column, so it overflowed
whenever the offline banner consumed vertical space or the viewport
was too short to fit all scanner cards. Wrap it in a
SingleChildScrollView, matching the other screens.

The version string was duplicated across six places. Collapse it to two
ecosystem sources of truth and derive the rest:
- backend/src/web_server.rs: omit the OpenAPI info.version so utoipa fills
it from CARGO_PKG_VERSION (backend/Cargo.toml); add a test pinning this.
- nix/package.nix: read the version from backend/Cargo.toml via fromTOML.
- nix/frontend.nix: read the version from frontend/pubspec.yaml by splitting
into lines (a whole-file regex triggers catastrophic backtracking in Nix's
regex engine).
- frontend/lib/about/about.dart: read the version at runtime via
package_info_plus instead of a hardcoded constant.
Also drop frontend/pubspec.lock.json: it is unreferenced (Nix's
autoPubspecLock generates its own JSON from pubspec.lock) and was going stale.

Break the 372-line frontend API client into focused files under
lib/utils/api/: error mapping (api_error.dart), Dio setup behind a
buildDio factory (dio_config.dart), and device/scanner/notification
endpoints as extensions in part files. Collapse the five near-identical
scanner-status methods via a generic _getModel helper and de-duplicate
the pagination logic via a shared _paginate helper.
The BackendAPI singleton and dioErrorToUserMessage remain importable
from oott_api.dart unchanged, so no call sites are affected.

Replace the lifetime "devices seen since start" counter in the mDNS, SSDP
and DHCP scanners with a rolling count of distinct devices (deduped by
MAC) seen within the last hour.
Each scanner's status now tracks a MAC -> last-seen-time map; the snapshot
prunes entries older than 60 minutes and reports the remaining count. The
API field name (devices_seen) is unchanged, so only its meaning and the
frontend labels ("N devices in the last hour") are updated.

The ARP and SNMP scanner status endpoints and front-end cards now expose
the number of devices found by the most recent successful scan, following
the existing mDNS device-count pattern. The count persists across the
running/waiting transitions, and for SNMP a failed poll keeps the last
good count rather than overwriting it.

Introduce a sixth scanner that periodically queries an SNMP agent
(typically the router/firewall) for its ARP/neighbour cache via
SNMPv2c and feeds discovered devices into the shared devices, events
and notifications pipeline. Unlike the ARP scanner it generates no
traffic on the local segment and can surface devices across all
subnets the agent routes.
Scope is intentionally minimal: SNMPv2c only, a single target, and the
ipNetToMediaTable (ARP) only. SNMPv3 and switch MAC/forwarding-table
polling are left as follow-ups in TODO.md.
- backend: csnmp dependency; SnmpScanner config (opt-in, off unless a
[snmp_scanner] section is present); DeviceEventScanner::Snmp;
scanners/snmp/{finder,scanner,status}; main.rs wiring; status API
endpoint wired into OpenAPI
- frontend: SNMP scanner status model, card, API method, status screen
and summary card rows, and device-event label
- docs/config: sample TOML, README options, NixOS module option, and
setup notes for enabling SNMP on pfSense/OPNsense

Add a DHCP scanner card to the Status screen and a DHCP row to the

Surface the SSDP/UPnP scanner alongside ARP and mDNS: a dedicated card on
the Status screen and a row in the consolidated Status card on Home. Mirrors

PolledValue infrastructure. Also maps the 'Ssdp' device-event scanner to the
"SSDP/UPnP" label.

Extract ScannerStatusCard<T> and PaginationBar so the ARP/mDNS cards and

Defense-in-depth: the persisted value is the (XOR-obfuscated) API key,
so a future SharedPreferences backend that surfaced the value in its
exception could leak it through the UI. Log the detail via debugPrint
and show a fixed message to the user instead.

Wrap main in runZonedGuarded and install FlutterError.onError /
PlatformDispatcher.onError so background async failures get logged
instead of dying silently. Guard PrefUtil.init so a SharedPreferences
platform error no longer aborts startup. Recognize TypeError and
FormatException in dioErrorToUserMessage to give a clearer message
when the backend returns an unexpected JSON shape or bad timestamp.
Wrap Settings._save in try/catch so prefs write failures show a
snackbar instead of leaving the Save button silently dead.

PrefUtil.setValue now returns the underlying SharedPreferences result
and throws on unsupported types; settings save reports failures rather
than always showing success. Device detail and event history report
the real Dio error message and skip cancellations.

Previously BackendAPI.test() called response.toString().contains('OOTT_API_OK'),
which scans the full stringified Response (status line, headers, body, request
path). A reverse proxy or captive portal returning HTML that happens to echo the
token would falsely pass the connectivity check. Compare response.data — the
JSON-decoded String the backend's /api/test handler returns — against the
expected value with exact equality instead.

Send no Authorization header at all on a fresh install (rather than
"Bearer " with an empty token), so the backend can distinguish "no

Adds a centralized BackendReachability singleton fed by a Dio
interceptor (connection-level failures only) and connectivity_plus.
PolledValue subscribes to it and pauses on offline / reloads
immediately on reconnect, replacing the previous per-card error
cascade. MainShell renders a global OfflineBanner with Retry and
Settings actions; cards downgrade error→stale when offline so the
banner is the only red element.

Remove dead _pageSize from BackendAPI and centralise the
"fetch perPage+1, detect hasNextPage, trim" logic into
listDevices and listNotifications. Both methods now accept
page/perPage and return ({items, hasNextPage}) records,
eliminating the duplicated boilerplate at each call site.

PolledValue gains pause()/resume() methods. ScannersStatusCard and
NotificationsList now implement RouteAware (didPushNext/didPopNext)
and WidgetsBindingObserver to stop API calls and tick timers when
the widget is not visible, resuming with an immediate fetch on return.

Transient network hiccups and temporary backend errors (5xx, timeouts)
now retry transparently up to twice (1 s then 3 s backoff) before
surfacing an error to the user. Non-idempotent methods (POST, PUT,
DELETE), cancellations, and non-retryable status codes are excluded.

Three intertwined fixes so that marking a notification as read from the
trailing menu, swipe-dismiss, and 'Mark all as read' all consistently
update the UI and surface backend failures.
- Guard the mark-read, mark-new, and mark-all calls with try/catch; on
failure show a snackbar with the mapped error and leave the list
untouched.
- Use the State's own `mounted` and `context` after the await instead of
the per-card BuildContext, so the SliverList rebuild reliably runs
even when the originating NotificationCard's element has been swapped
out by the reconciliation. _setRead and _markAllAsRead no longer take
a BuildContext.
- Replace `Dismissible(key: UniqueKey())` with `ValueKey(item.id)` in
the notification card. UniqueKey was regenerated on every build,
forcing the Dismissible/PopupMenuButton subtree to be disposed on any
parent rebuild; the open menu's `mounted` check would then drop
`onSelected` silently.
- Add `ValueKey(device.macAddress)` to the device list rows for the
same reason, anchoring each row's Element (and its PopupMenuButton
State) to its device identity instead of its list position.

The four polling status cards (ARP, mDNS, scanners summary, devices
summary) each rolled their own Timer/_status/_error/_isLoading state and
flipped to a red 'Error' UI on the first failed poll, throwing away
last-known-good data that was still in memory. A momentary backend blip
made every card flash red.
Introduce PolledValue<T>, a ChangeNotifier that owns the periodic timer,
in-flight CancelToken, last value, last error, and a freshness
classification (initialLoading / fresh / stale / error). 'stale' kicks in
on the first failure but keeps the value visible; 'error' only takes over
after staleErrorAfter elapses without a success (30s for the 5s scanner
polls, 3min for the 1min device-summary poll). All four cards now branch
on freshness and show a small live-updating warning icon with a tooltip
('Last updated N ago — <error>') while stale, instead of flipping red.
Also threads CancelToken? through the three polled GET endpoints.

Every BackendAPI method had hand-rolled 'About to call ...' and
'Received: ...' debug lines, and the constructor printed the base URL and
a masked API-key marker. Replace all of that with a single LogInterceptor
attached under `if (kDebugMode)` to both the singleton Dio and the
ephemeral Dio used by BackendAPI.test(). Headers and bodies are kept off
so the Authorization bearer never lands in the console. The interceptor
is tree-shaken from release builds.

Rapidly switching filter chips, sort columns, or pagination on the devices
and notifications lists could overlap fetches, and an older response
landing after a newer one would silently overwrite the list with results
that no longer match the active query.
Thread an optional CancelToken into listDevices and listNotifications.
Each State now keeps one active token, cancels it on every new fetch and
on dispose, and bails from both success and catch branches when its token
has been superseded. DioExceptionType.cancel is silenced so internal
cancellations don't surface as user-visible errors. The notifications
list's prior `if (_isLoading) return;` guard is removed so the 1-min
periodic refresh is no longer skipped during user activity.

Settings._save wrote new base_url/api_key to prefs but the BackendAPI
singleton kept the Dio it built at first access, so URL/key changes only
took effect after an app restart. Expose reconfigureFromPrefs() on
BackendAPI and call it from Settings._save so subsequent requests pick up
the new config immediately.

Set 5s/15s/15s connect/receive/send timeouts so calls fail fast instead of
hanging. Introduce dioErrorToUserMessage() and route DioException-throwing
call sites (device actions, devices list, notifications list, scanners
status card) through it, replacing raw e.toString() output. Notifications
list now surfaces load errors inline in the theme's error color, matching
the devices list pattern. Status dots show the mapped detail as a tooltip.
Stop logging the API key in cleartext.

Extend PUT /api/devices/{mac} to accept an optional name and surface an

GET /api/devices accepts sort_by/sort_order (whitelisted columns; default
last_seen DESC, stable secondary sort on mac_address), device registration
