James RichandClaude Sonnet 5 59fc12b4a8 fix(node): stop rendering saved-on-phone nodes as freshly heard
Root-caused via #6682/#6693: Node.hopsAway defaults to the sentinel -1
instead of null, and nothing distinguished a locally-retained node from
one the connected radio just reported this session. Together that made
a legitimately cached row (multi-radio use, or a radio with a smaller
NodeDB than the phone) render as if it were freshly heard with 0 hops,
0 SNR, 0 RSSI.

- Add Node.hopsAwayOrNull, extending the existing snrOrNull/rssiOrNull
  pattern, and fix both copies of getRelayNode (the live one in
  Packet.kt and the unused one in Node.kt) whose plain
  minByOrNull { it.hopsAway } let the unresolved -1 sentinel look
  closer than a real hop count.
- Track the current connection session's exact NodeDB membership via
  NodeManager.currentSessionNodeNums, published right after each Stage
  2 handshake and reconciled against the same generation-race window
  already used for connectionIdentity.
- Add a "Saved on phone" badge (node list rows + detail screen) for any
  node retained locally but absent from that snapshot, and stop those
  rows from claiming "online" from a cached, no-longer-current
  lastHeard (list rows, a11y description).

New/updated tests across core:model, core:data, core:ui, core:database
and feature:node; screenshot goldens regenerated for the new "Saved on
phone" previews. Full baseline
(spotlessApply/spotlessCheck/detekt/assembleDebug/test/allTests) and
:screenshot-tests:validateDebugScreenshotTest are green.

Fixes #6263

:core:model (Meshtastic Domain Models)

Overview

The :core:model module is a Kotlin Multiplatform (KMP) library containing the domain models and data classes used throughout the application and its API. These models are platform-agnostic and designed to be shared across Android, JVM, and future supported platforms.

Multiplatform Support

Models are plain commonMain Kotlin types — @Serializable (kotlinx.serialization) data classes and @JvmInline value classes — with no Android Parcelable dependency, so they are shared verbatim across Android, JVM, and iOS.

Key Models

  • DataPacket: Represents a mesh packet (text, telemetry, etc.).
  • Node: Contains detailed information about a node (position, SNR, battery, etc.).
  • NodeAddress / ContactKey: Type-safe node addressing (Broadcast/Local/ByNum/ById) and contact-key parsing, replacing stringly-typed "^all"/"!hex" handling.
  • DeviceHardware: Represents supported Meshtastic hardware devices and their capabilities.
  • Channel: Represents a mesh channel configuration.

Usage

This module is a core dependency of most feature modules.

// In commonMain
implementation(projects.core.model)

Structure

  • commonMain: Contains the majority of domain models and logic.
  • androidMain: Contains Android-specific utilities and implementations for expect declarations.
  • androidUnitTest: Contains unit tests that require Android-specific features (like Parcel testing via Robolectric).
