- Add rankings StateFlow to DiscoverySummaryViewModel
- Compute rankings from PresetRankingInput on loadNodes and rerunAnalysis
- Pass rank/isTied to PresetResultCard for display
- Show rank badge (#1, #2, tied) in preset header
- Rank 1 (untied) highlighted in primary color
Validated: spotlessApply, allTests, compileKotlinJvm
Implement the spec's ranking and recommendation heuristic:
1. Highest unique discovered node count
2. Highest neighbor-report diversity (direct + mesh)
3. Highest non-duplicate packet count
4. Best median link quality (SNR first, then RSSI)
5. Greatest best known distance
6. Lowest failure/reconnect penalty
Presets tied after all 6 criteria share the same rank with isTied=true.
Includes RankingScoreBreakdown for transparent per-criterion scoring.
11 unit tests covering each criterion as tiebreaker, full ties,
edge cases (empty/single preset, no nodes, failed presets).

- Add Preparing, Cancelling, Failed states to DiscoveryScanState (FR-008)
- Change Complete to data class with CompletionOutcome enum
- Add local-mesh-discovery deep link routes to DeepLinkRouter (FR-031)
- Compute packetSuccessRate/packetFailureRate in scan engine (FR-012)
- Fix DiscoveryScanEngineTest compilation and restructure with shared scheduler
- All 8 tests pass, kmpSmokeCompile clean
- Replace platform-specific `String.format` with Kotlin standard library `padStart` in `DwellProgressIndicator` to support common code.
- Simplify fully qualified icon references in `DiscoveryGoogleMap` by adding explicit imports.
- Implement distance tracking using `latLongToMeter` and a new `getMaxDistance` DAO query
- Calculate Airtime Rate as a delta over time to align with telemetry specifications
- Capture and restore the full `LoRaConfig` instead of just the modem preset after a scan
- Persist local radio statistics (Tx/Rx counts, uptime, relay stats) in preset results
- Backfill missing node names and positions from the local NodeDB during discovery
- Refactor `DiscoveryScanEngine` to use injected `CoroutineDispatchers` and `ApplicationCoroutineScope`
- Reduce BLE connection priority request delay in `BleRadioTransport` to 1 second
- Improve test reliability by replacing fixed `Thread.sleep` calls with state-based polling and `delay`
* Introduce a new `:feature:discovery` module for scanning mesh topology across multiple LoRa presets
