# Session Delta — 2026-05-28 (2nd pass)

## Authoritative Project Location

**Working copy:** `~/nexstream/` (273 Kotlin files, gradlew present, 131 tests)
**Fresh extraction:** `~/projects/nexstream/` (created from `~/projects/nexstream.tar.gz`, 119 files, no tests, no gradlew)

Always use `~/nexstream/` — it's the live working copy with all previous session fixes applied.

## Session Fixes Applied

### Force-unwrap elimination (final 2)
- `TorBoxClient.kt:73` — `result.files!!.mapNotNull` → `result.files?.mapNotNull ?: emptyList()`
- `OnboardingViewModel.kt:196` — `states[provider]!!.copy(` → `states[provider]?.let { ... } ?: return@update state`

### Updates tab — real version comparison
`AddonsViewModel.kt:346-361` — `checkForUpdates()` previously hardcoded `addonsWithUpdates = emptyList()`.
Now: snapshots old versions before refresh, refreshes all addons in parallel, compares old vs new,
filters to user (non-system) addons only.

```kotlin
fun checkForUpdates() {
    viewModelScope.launch {
        _uiState.value = _uiState.value.copy(isCheckingUpdates = true)
        val addons = addonRepository.addons.value

        // Snapshot old versions before refresh
        val oldVersions = addons.associate { it.id to it.manifest?.version }

        // Refresh all addon manifests in parallel
        addons.map { addon ->
            launch { addonRepository.refreshAddon(addon.id) }
        }.forEach { it.join() }

        // Compare old vs new versions (user addons only)
        val updated = addonRepository.addons.value.filter { addon ->
            !addon.isSystem &&
            addon.manifest != null &&
            addon.manifest?.version != null &&
            addon.manifest?.version != oldVersions[addon.id]
        }

        _uiState.value = _uiState.value.copy(
            isCheckingUpdates = false,
            addonsWithUpdates = updated,
        )
    }
}
```

## Test Breakdown (131 total, all passing)

| Suite | Tests | Area |
|---|---|---|
| RealDebridClientTest | 25 | Debrid API client |
| SourceRankerTest | 41 | Stream ranking + device caps |
| ContentFilterTest | 17 | Kids-mode safety |
| PlaybackOrchestratorTest | 16 | Playback handoff + fallback |
| StreamValidatorTest | 13 | URL validation |
| StreamDeduplicatorTest | 13 | Dedup + geometric rounding |
| FallbackEngineTest | 6 | Retry + fallback logic |

## Remaining Work (priority order)

1. `./gradlew :app:assembleRelease` — verify ProGuard doesn't break serialization
2. Add cert pinning to OkHttp clients (DebridModule, TraktModule, TmdbModule)
3. Gate P2P addon installs on `requiresDebrid` check in `AddonsViewModel.installAddon()`
4. Wire `ResolutionCutoff`/`QualityPreference` into `SourcePreferences` in `DetailsViewModel`
5. Add loading skeletons to HomeScreen, SearchScreen
6. Write ViewModel tests (requires Hilt test setup)
7. Real-device smoke test on Android TV
