chore(repo): untrack macOS chanora_bridge.framework build artifacts

The macOS chanora_bridge.framework tree at apps/chanora_flutter/macos/Frameworks/chanora_bridge.framework was being tracked in git despite being a pure build artifact. Both mechanisms in chanora_bridge.podspec rebuild the entire tree from scratch: * prepare_command (runs on `pod install`) — `rm -rf $FW` and reconstructs Versions/A, the Versions/Current and Resources symlinks, Info.plist, and copies the lipo-merged universal dylib. * script_phase :before_compile (runs on every Xcode build) — same rm -rf + reconstruction, gated on freshness of the cargo output. Tracking the tree therefore added zero value and ~36 MB per binary revision (the chanora_bridge dylib alone). The iOS counterpart at apps/chanora_flutter/ios/Frameworks/ has been correctly ignored since .gitignore:118-119 was added; this commit mirrors that rule for macOS. Changes: - git rm --cached -r the 5 tracked entries (binary, 3 symlinks, Info.plist). Working tree is untouched, so existing local builds keep functioning until the next `pod install` / Xcode build refreshes them. - Add /apps/chanora_flutter/macos/Frameworks/ to .gitignore alongside the existing iOS entry, with a comment pointing at the podspec mechanism so the next maintainer understands the rule. Verified the working tree binary survives the cache untrack and the path is now matched by .gitignore:125.

 // Force the linker to retain Swift @_cdecl symbols that the chanora_bridge
 // Rust framework resolves at runtime via dlsym(RTLD_DEFAULT). Two flags per
 // symbol, intentionally redundant:
 //
 //   -u _sym                marks the symbol as force-undefined at link time,
 //                          which keeps the object that defines it from being
 //                          dropped and prevents dead-strip from removing the
 //                          definition. This is the load-bearing flag.
 //   -exported_symbol _sym  re-exports the symbol in the final binary's
 //                          dynamic symbol table so dlsym(RTLD_DEFAULT) can
 //                          find it from the Rust framework at runtime.
 //
 // Without -u, Xcode Archive's -dead_strip (WMO + LTO) can remove the
 // symbol before the export list is applied, and CoreML VAD silently falls
 // back to WebRTC on TestFlight / App Store. The Swift-side static
 // `unsafeBitCast` references in SileroCoreMLBridge.swift are belt-and-
 // suspenders defense-in-depth, NOT the primary guarantee.

 The bridge is the trust and type boundary between Flutter and Rust. Flutter must not directly depend on protocol-library internals. Rust core must not expose platform-specific storage or audio details to UI code except through stable DTOs and capability fields.
 Current Core locality note: the public Core Interface remains available through `chanora_core::*` re-exports, while branch `simplify-project-review` has started moving internal Core responsibilities into focused Modules (`events.rs`, `network_diagnostics.rs`). This is an internal maintainability split, not a public Interface change.

 # Chanora Maintainability Review — 2026-06-08
 **Document status:** Working-branch review record
 **Branch:** `simplify-project-review`
 **Scope:** Project-wide simplification, fail-safe, and verification review
 ## 1. Purpose
 This record captures the current maintainability review so implementation, verification, and release documents do not drift behind the code. It focuses on unnecessary Modules, shallow Interfaces, duplicate Implementations, built-in replacement opportunities, and fail-safe gaps that need explicit evidence before release claims.
 ## 2. Changes Already Applied on the Branch
 | Area | Files | Maintainability result |
 |---|---|---|
 | Core event DTO locality | `core/chanora_core/src/events.rs`, `core/chanora_core/src/lib.rs` | Public Core event DTOs moved out of the oversized Core integration Module while preserving the public `chanora_core::*` Interface through re-exports. |
 | Core network diagnostics locality | `core/chanora_core/src/network_diagnostics.rs`, `core/chanora_core/src/lib.rs` | Private network diagnostic ring-buffer state and its regression test now live next to the Implementation they protect. |
 | Bounded queues | `core/chanora_core/src/network_diagnostics.rs`, `crates/chanora_diagnostics/src/lib.rs` | Replaced `Vec + remove(0)` queue behaviour with `VecDeque`, reducing custom queue code and avoiding O(n) front removal. |
 | PTT backend errors | `crates/chanora_audio/src/ptt_backends/mod.rs` | Replaced manual `Display` / `Error` Implementation with existing `thiserror::Error`; regression test keeps user-facing strings stable. |
 | Render downmix | `crates/chanora_audio/src/voice_render.rs`, `crates/chanora_audio/src/ios_raw_unit.rs` | Removed duplicate mono-i16 downmix loop by using the interleaved helper with one output channel. |
 | State reducer | `crates/chanora_state/src/lib.rs` | Reused the main snapshot reducer for reconnect snapshots instead of duplicating normalization and delta construction. |
 | Workspace metadata | `crates/chanora_resolver/Cargo.toml`, `Cargo.lock` | Resolver inherits workspace package metadata, improving release metadata Locality. |
 | Flutter voice fail-safes | `apps/chanora_flutter/lib/main.dart`, `apps/chanora_flutter/lib/widgets/voice_compact.dart`, `apps/chanora_flutter/lib/services/ios_audio_session_controller.dart` | Commit `d835394` preserves independent mute owners, releases touch PTT on disposal while held, and catches iOS audio-session `MissingPluginException` / activation failures so they do not become unhandled async errors. |
 | Rust realtime callback hardening | `crates/chanora_audio/src/android_voice_unit.rs`, `crates/chanora_audio/src/ios_raw_unit.rs`, `crates/chanora_audio/src/engine.rs` | Commit `8606eb4` hardens Android/iOS realtime callback paths. The current branch also migrates the Android-only JNI paths to `jni-rs` 0.22 so the supported ARM64 Android debug build compiles. Full lock-free audio-handler/config/debug-recorder redesign remains follow-up work. |
 ## 3. Remaining Simplification Opportunities
 | Recommendation | Candidate files | Strength | Notes |
 |---|---|---|---|
 | Continue splitting Core internals by responsibility | `core/chanora_core/src/lib.rs` | Strong | Next slices should be reconnect/session, voice projection, storage helpers, and diagnostics export. Keep public re-exports stable. |
 | Make Bridge depend on Core rather than Audio where possible | `crates/chanora_bridge/Cargo.toml`, `crates/chanora_bridge/src/api.rs`, `core/chanora_core/src/lib.rs` | Worth exploring | The Bridge currently has a direct audio edge. Apply the deletion test before removing it. |
 | Decide whether prefetch deserves a crate-level Seam | `crates/chanora_prefetch/src/lib.rs`, `crates/chanora_resolver/src/lib.rs`, `core/chanora_core/src/lib.rs` | Worth exploring | Prefetch is a small TTL cache and fire-and-forget resolver Adapter. Merge into resolver if it is resolver policy; merge into Core if it is app orchestration policy. |
 | Consolidate protocol/core/bridge event catalogues | `crates/chanora_protocol/src/dto.rs`, `core/chanora_core/src/events.rs`, `crates/chanora_bridge/src/api.rs` | Worth exploring | Protocol-owned deltas and Core-owned lifecycle events are currently mirrored through multiple DTO layers. |
 | Reduce bridge DTO mirror boilerplate | `crates/chanora_bridge/src/api.rs` | Worth exploring | Verify Flutter Rust Bridge support before deleting mirrors. If mirrors remain required, centralize conversion patterns and keep field order aligned with Core DTOs. |
 | Clarify protocol voice packet exception | `crates/chanora_protocol/src/lib.rs`, `crates/chanora_audio/Cargo.toml` | Worth exploring | The protocol crate documents `tsclientlib` isolation but deliberately re-exports voice packet types for audio. Document this as an explicit voice wire Seam or move packet construction fully into protocol. |
 | Remove shallow audio helpers only after public API check | `crates/chanora_audio/src/processor/noop.rs`, `crates/chanora_audio/src/processor/platform.rs`, `crates/chanora_audio/src/frame.rs` | Speculative | These Modules are shallow, but deletion must wait until external/public API expectations are checked. |
 | Redesign remaining audio shared state outside realtime callbacks | `crates/chanora_audio/src/engine.rs`, platform voice units, debug recorder/config paths | Strong follow-up | The focused callback hardening is complete, but a full lock-free `AudioHandler` / config / debug-recorder redesign should be planned separately and verified on device. |
 | Review protocol/core disconnect and control-plane bounds | `core/chanora_core/src/lib.rs`, `crates/chanora_protocol/src/adapter.rs` | Strong follow-up | Unless closed by a later code slice, sustained voice traffic and broken transport should be reviewed for bounded control request and disconnect progress. |
 ## 4. Fail-Safe Gaps That Need Evidence
 | Gap | Risk | Required evidence before release claim |
 |---|---|---|
 | Android Keystore-backed DEK remains deferred | Android identity/bookmark encryption has weaker fail-safe properties than final target secure-storage design. | Android secure-storage audit or waiver; explicit release-readiness limitation. |
 | Android permission/audio lifecycle needs deeper route exercise | Build/install/launch smoke now passes on the emulator, but full permission-flow and audio-route lifecycle behavior still need an interactive scenario or device test before release. | Device/emulator scenario covering permission request/denial/grant, voice controls, foreground service, audio focus, and route/SCO transitions. |
 | iOS device runtime verification not executed in this review | The iOS audio-session error path is hardened, but VoiceProcessingIO/session ordering and runtime audio behavior still need device evidence. | iOS device or simulator build/run plus audio-session smoke evidence before iOS runtime success is claimed. |
 | VAD / VoiceActivity wording drift | VAD assets, tests, and scaffolding exist, but product-enabled `VoiceActivity` remains reserved/disabled per DEC-030. | Release, README, and verification wording must distinguish scaffolding/assets/tests from shipped product behavior. |
 | Protocol voice packet re-export is an intentional exception | Future maintainers may assume complete protocol isolation and accidentally widen the Seam. | Architecture note in SAD/SDD or a decision-register entry. |
 | Bridge DTO mirror drift | Field additions can be missed across Core, Bridge, and Dart generated DTOs. | Bridge generation check plus Flutter analyze/test after bridge DTO changes. |
 | Full live reducer integration remains separate from reducer unit coverage | State reducer tests are strong, but runtime UI still has snapshot/probe paths. | SWE.5 integration run proving live protocol events fold through the intended state path, or explicit P1 deferral. |
 | Event replay tooling remains absent | Replay-based diagnosis and regression reproduction are limited. | Event replay tool implementation or waiver. |
 ## 5. Verification Policy for Future Code Changes
 | Change type | Required verification |
 |---|---|
 | Rust-only change | `cargo fmt --all`, `cargo check --workspace`, `cargo test --workspace` |
 | Bridge DTO/API change | Rust verification plus bridge generation check, `flutter analyze`, and `flutter test --exclude-tags e2e` in `apps/chanora_flutter` |
 | Android platform/audio/permission change | Rust/Flutter verification plus NDK target compilation, `adb devices -l`, Android build/install, and a device or emulator smoke test |
 | Documentation-only change | Read affected docs and ensure cross-links/document index stay current; code tests are not required unless docs describe a code change just made |
 ## 6. Android ADB Status for This Review
 `adb devices -l` now reports an authorized emulator target:
 ```text
 emulator-5554          device product:sdk_gphone64_arm64 model:sdk_gphone64_arm64 device:emu64a transport_id:1
 ```
 Android default debug build still fails because SDD-118 excludes `armeabi-v7a`; use a supported ABI target. ARM64 debug build/install/launch smoke evidence from 2026-06-08:
 ```text
 flutter build apk --debug --target-platform android-arm64
 ✓ Built build/app/outputs/flutter-apk/app-debug.apk
 adb -s emulator-5554 install -r apps/chanora_flutter/build/app/outputs/flutter-apk/app-debug.apk
 Success
 adb -s emulator-5554 shell am start -W -n app.chanora.chanora_flutter/.MainActivity
 Status: ok
 LaunchState: COLD
 Activity: app.chanora.chanora_flutter/.MainActivity
 TotalTime: 6514
 adb -s emulator-5554 shell pidof app.chanora.chanora_flutter
 7287
 ```
 `dumpsys window app.chanora.chanora_flutter` showed `MainActivity` visible with `isReadyForDisplay()=true`, and `dumpsys activity top` showed `app.chanora.chanora_flutter/.MainActivity` resumed with window focus. This is build/install/launch smoke evidence only; permission-flow success and audio-lifecycle success are not claimed by this review.
 ## 7. Release and Documentation Alignment Notes
 - Android minimum runtime baseline is API 28 (Android 9.0) per SysRS-288, SRS-187, DEC-004, and the Gradle `minSdk = 28` configuration. Documents must not revive the older API 24 baseline.
 - Flutter app version/build is `0.3.0+100` in `apps/chanora_flutter/pubspec.yaml`. Rust workspace package version remains `0.2.0-beta.1`. Release documents must distinguish these values instead of treating them as one candidate version.
 - The v0.3.0 changelog entry may mention VAD assets/backends only as implementation scaffolding; product-enabled `VoiceActivity` remains disabled/coming-soon until DEC-030 is superseded and runtime verification exists.
 - README wording must describe the existing Flutter/Rust workspace and app scaffold, not a future scaffold that has not been created.

 # Chat Panel Switching Implementation Plan
 > **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
 **Goal:** Enable in-place conversation switching in the expanded 3-panel layout, add per-conversation draft persistence, and improve unread awareness — matching industry-standard UX patterns from Discord/Slack/Telegram/Element.
 **Architecture:** The expanded layout (≥1024dp) shows voice controls | channel tree | inline chat panel. Currently the chat panel locks to one conversation with no way to switch from the channel tree. The fix adds channel→chat triggers, in-place target swapping, per-target draft storage, and preserves chat state across switches. The state machine (`_inlineChatTarget` + `_chatOpen`) already supports switching — we just need UI affordances and draft persistence.
 **Tech Stack:** Flutter/Dart, existing `BridgeMessageTarget` sealed class, existing `ChatDetailView` / `ChatPanel` / `SnapshotView` widgets.
 **Design research basis:** Discord (in-place swap, dot/badge unread hierarchy), Telegram Desktop (adaptive 3-tier layout, per-conversation drafts + scroll anchoring), Element (per-room panel state, toggleable right panel), Slack (bold sidebar for unread, split view). All apps treat DMs and channels identically for switching behavior.
 ---
 ## Current State
 | UX Element | Status |
 |---|---|
 | Unread indicator | Single global badge count on app bar chat button |
 | Channel → chat trigger | **None.** Channel tiles only join voice |
 | Client → DM trigger | Works (right-click → "Direct Message") |
 | Header chat button when panel open | Idempotent — re-uses same `_inlineChatTarget` |
 | Draft persistence | None — single `TextEditingController`, lost on switch |
 | Scroll position memory | None — always auto-scrolls to bottom |
 | Per-conversation unread | None |
 ## Scope
 **In scope (this plan):**
 - Channel → chat switching in expanded layout
 - Channel right-click → "Chat" option
 - Header chat button → switch to current voice channel chat when panel already open
 - Per-target draft persistence (in-memory `Map`)
 - Close = dismiss (remember last target and draft)
 - Unread dot indicator on channels in `SnapshotView`
 **Out of scope (future):**
 - Scroll position memory per target
 - "New messages" divider
 - Per-target unread counts / badge numbers
 - Notification tiering (dot/badge/mention)
 - Split view (Slack power-user feature)
 ## Responsive Behavior
 | Tier | Width | Chat Mode | Changes in this plan |
 |---|---|---|---|
 | **Expanded** | ≥1024dp | Inline `ChatPanel` (right column) | ✅ All changes apply here |
 | **Medium** | 600–1023dp | Full-screen `ChatPage` route | No changes needed (already works) |
 | **Compact** | <600dp | Full-screen `ChatPage` route | No changes needed (already works) |
 ---
 ## File Structure
 | File | Action | Responsibility |
 |---|---|---|
 | `apps/chanora_flutter/lib/widgets/snapshot_view.dart` | **Modify** | Add `onOpenChannelChat` callback, channel context menu with "Chat" option, unread dot on channels |

 ### Task 1: Add `onOpenChannelChat` callback to `SnapshotView`
 **Files:**
 - Modify: `apps/chanora_flutter/lib/widgets/snapshot_view.dart:26-63` (constructor params)
 - Modify: `apps/chanora_flutter/lib/widgets/snapshot_view.dart:203-284` (`_channelTile`)
 - [ ] **Step 1: Add the callback field to `SnapshotView` widget**
 In `snapshot_view.dart`, add a new optional callback field after `onOpenClientPoke` (around line 71):
 ```dart
  /// Open chat for a channel.
  final ValueChanged<rust.BridgeChannel>? onOpenChannelChat;
 ```
 Update the constructor to include it (around line 32, after `onOpenClientPoke`):
 ```dart
    this.onOpenChannelChat,
 ```
 - [ ] **Step 2: Add a right-click/long-press context menu to `_channelTile`**
 Replace the `InkWell` in `_channelTile` (lines 243-284) with a context menu wrapper. The channel tile should support:
 - **Tap**: join voice (existing behavior, unchanged)
 - **Right-click / long-press**: show a popup menu with "Open chat" option
 ```dart
    return InkWell(
      onTap: onTap,
      onLongPress: widget.onOpenChannelChat != null
          ? () => widget.onOpenChannelChat!(channel)
          : null,
      child: PopupMenuButton<String>(
        position: PopupMenuPosition.under,
        enabled: widget.onOpenChannelChat != null,
        onSelected: (value) {
          if (value == 'chat') {
            widget.onOpenChannelChat?.call(channel);
          }
        },
        itemBuilder: (context) => [
          PopupMenuItem(
            value: 'chat',
            child: Row(
              children: [
                const Icon(Icons.chat_bubble_outline, size: 18),
                const SizedBox(width: 12),
                Text(AppLocalizations.of(context)!.chatAction),
              ],
            ),
          ),
        ],
        child: ConstrainedBox(
          constraints: const BoxConstraints(minHeight: 40),
          child: Row(
            children: [
              SizedBox(width: channelIndent),
              _expandButton(
                theme,
                hasVisibleChildren: hasVisibleChildren,
                expanded: expanded,
                onPressed: onToggleExpanded,
              ),
              SizedBox(
                width: _channelIconColumnWidth,
                child: Align(
                  alignment: Alignment.centerLeft,
                  child: Icon(
                    Icons.tag,
                    color: theme.colorScheme.onSurfaceVariant,
                  ),
                ),
              ),
              const SizedBox(width: _channelTextGap),
              Expanded(
                child: Text(
                  channel.name,
                  maxLines: 1,
                  overflow: TextOverflow.ellipsis,
                ),
              ),
              if (channel.hasPassword) ...[
                const SizedBox(width: 8),
                Icon(
                  Icons.lock_outline,
                  color: theme.colorScheme.onSurfaceVariant,
                ),
              ],
            ],
          ),
        ),
      ),
    );
 ```
 Note: The `PopupMenuButton` wraps the existing content as its `child`, so the tile looks identical until right-clicked. The `onTap` on `InkWell` continues to handle voice join.
 - [ ] **Step 3: Run `flutter analyze`**
 Run: `cd apps/chanora_flutter && flutter analyze`
 Expected: No new errors (the callback is optional, so existing call sites compile without changes)
 - [ ] **Step 4: Commit**
 ```bash
 git add apps/chanora_flutter/lib/widgets/snapshot_view.dart
 git commit -m "feat(chat): add onOpenChannelChat callback with context menu to channel tiles"
 ```
 ---
 ### Task 2: Wire `onOpenChannelChat` in `main.dart` and add per-target draft storage
 **Files:**
 - Modify: `apps/chanora_flutter/lib/main.dart:370-374` (state fields)
 - Modify: `apps/chanora_flutter/lib/main.dart:2521-2540` (SnapshotView constructor)
 - [ ] **Step 1: Add draft storage map**
 Add a new state field near line 374 (after `_inlineChatCollapseNoticeShown`):
 ```dart
  /// Per-target draft text. Populated when switching away from a conversation
  /// so the user's unfinished message is preserved.
  final Map<String, String> _chatDrafts = {};
 ```
 - [ ] **Step 2: Add `_lastDismissedTarget` field**
 Add a new state field to remember the last dismissed target so reopening returns to it:
 ```dart
  /// The last chat target before the panel was closed. Used to restore the
  /// previous conversation when the user reopens chat.
  rust.BridgeMessageTarget? _lastDismissedTarget;
  String _lastDismissedClientName = '';
 ```
 - [ ] **Step 3: Wire `onOpenChannelChat` in `SnapshotView` constructor**
 In the `SnapshotView(...)` constructor around line 2512, add the new callback:
 ```dart
                        onOpenChannelChat: (channel) => unawaited(
                          _onOpenChat(
                            target: rust.BridgeMessageTarget.channel(channel.id),
                          ),
                        ),
 ```
 - [ ] **Step 4: Run `flutter analyze`**
 Run: `cd apps/chanora_flutter && flutter analyze`
 Expected: No new errors
 - [ ] **Step 5: Commit**
 ```bash
 git add apps/chanora_flutter/lib/main.dart
 git commit -m "feat(chat): add per-target draft storage and wire onOpenChannelChat"
 ```
 ---
 ### Task 3: Fix `_onOpenChat` to support switching and draft save/restore
 **Files:**
 - Modify: `apps/chanora_flutter/lib/main.dart:1628-1685` (`_onOpenChat` and `_closeInlineChat`)
 - [ ] **Step 1: Update `_onOpenChat` to save current draft and restore new target's draft**
 Replace the `_onOpenChat` method (lines 1628-1676) with logic that:
 1. Saves the current `_inlineChatTarget` draft before switching
 2. Restores the new target's draft (if any)
 3. When called with no explicit target and panel is already open, switches to current voice channel's chat
 ```dart
  Future<void> _onOpenChat({
    rust.BridgeMessageTarget? target,
    String clientName = '',
  }) async {
    final initialSnapshot = _snapshot!;
    // Resolve the new target.
    // If no target passed and panel is already open, switch to current voice channel.
    // If no target passed and panel is closed, resolve from history or default.
    rust.BridgeMessageTarget newTarget;
    if (target != null) {
      newTarget = target;
    } else if (_chatOpen && _currentVoiceChannelId != null) {
      newTarget = rust.BridgeMessageTarget.channel(_currentVoiceChannelId!);
    } else if (_inlineChatTarget != null) {
      newTarget = _inlineChatTarget!;
    } else {
      newTarget = resolveInitialChatTarget(
        messages: _chatMessages,
        currentVoiceChannelId: _currentVoiceChannelId,
      ) ?? const rust.BridgeMessageTarget.server();
    }
    final newClientName = clientName.isNotEmpty
        ? clientName
        : (newTarget == _inlineChatTarget) ? _inlineChatClientName : '';
    final isExpanded =
        layoutClassFromWidth(MediaQuery.sizeOf(context).width) ==
        LayoutClass.expanded;
    if (isExpanded) {
      setState(() {
        // Save draft for the current target before switching.
        _saveCurrentDraft();
        _chatUnread = 0;
        _chatOpen = true;
        _inlineChatTarget = newTarget;
        _inlineChatClientName = newClientName;
        _inlineChatCollapseNoticeShown = false;
      });
      return;
    }
    setState(() {
      _chatUnread = 0;
      _chatOpen = true;
    });
    await Navigator.of(context).push(
      MaterialPageRoute(
        builder: (_) => ChatPage(
          messages: _chatMessages,
          snapshot: initialSnapshot,
          messagesSource: () => _chatMessages,
          snapshotSource: () => _snapshot ?? initialSnapshot,
          refreshListenable: _chatFeedRevision,
          initialTarget: newTarget,
          initialClientName: newClientName,
          onTs3ServerLink: _onTs3ServerLink,
        ),
      ),
    );
    if (mounted) setState(() => _chatOpen = false);
  }
 ```
 - [ ] **Step 2: Add `_saveCurrentDraft` and `_draftKeyForTarget` helper methods**
 Add these near `_onOpenChat`:
 ```dart
  /// Converts a [rust.BridgeMessageTarget] to a stable string key for draft storage.
  String _draftKeyForTarget(rust.BridgeMessageTarget target) {
    return switch (target) {
      rust.BridgeMessageTarget_Server() => 'server',
      rust.BridgeMessageTarget_Channel(:final id) => 'channel:$id',
      rust.BridgeMessageTarget_Client(:final id) => 'client:$id',
      rust.BridgeMessageTarget_Poke(:final id) => 'poke:$id',
    };
  }
  /// Saves the current draft text (if any) for the current inline chat target.
  /// Called before switching targets or closing the panel.
  void _saveCurrentDraft() {
    // Note: The actual draft text is read from ChatDetailView's
    // TextEditingController via a callback. This is wired in Task 4.
  }
 ```
 Note: `_saveCurrentDraft` will be completed in Task 4 when we wire the draft callback from `ChatDetailView`.
 - [ ] **Step 3: Update `_closeInlineChat` to preserve last target instead of nulling it**
 Replace `_closeInlineChat` (lines 1678-1685):
 ```dart
  void _closeInlineChat() {
    setState(() {
      // Save draft before closing.
      _saveCurrentDraft();
      // Remember the last target so reopening returns to it.
      _lastDismissedTarget = _inlineChatTarget;
      _lastDismissedClientName = _inlineChatClientName;
      _chatOpen = false;
      // Do NOT null _inlineChatTarget — we want to remember it for reopen.
    });
  }
 ```
 - [ ] **Step 4: Run `flutter analyze`**
 Run: `cd apps/chanora_flutter && flutter analyze`
 Expected: No new errors
 - [ ] **Step 5: Commit**
 ```bash
 git add apps/chanora_flutter/lib/main.dart
 git commit -m "feat(chat): switch chat target on channel click, save draft before switching, preserve target on close"
 ```
 ---
 ### Task 4: Add draft save/restore callback to `ChatDetailView` and `ChatPanel`
 **Files:**
 - Modify: `apps/chanora_flutter/lib/widgets/chat_views.dart:1054-1098` (`ChatDetailView` constructor + state)
 - Modify: `apps/chanora_flutter/lib/widgets/chat_panel.dart:12-75` (`ChatPanel` constructor + build)
 - [ ] **Step 1: Add draft callbacks to `ChatDetailView`**
 Add two new optional callbacks to `ChatDetailView` (after `messageMaxWidth` around line 1066):
 ```dart
  /// External draft text to restore when the widget initializes or the target changes.
  final String? restoredDraft;
  /// Called with the current draft text whenever the target changes or the widget is disposed.
  final ValueChanged<String>? onDraftChanged;
 ```
 - [ ] **Step 2: Implement draft restore in `_ChatDetailViewState`**
 In `_ChatDetailViewState` (line 1100), add `initState` and `didUpdateWidget` to handle drafts:
 ```dart
  @override
  void initState() {
    super.initState();
    if (widget.restoredDraft != null && widget.restoredDraft!.isNotEmpty) {
      _textCtl.text = widget.restoredDraft!;
    }
  }
  @override
  void didUpdateWidget(covariant ChatDetailView oldWidget) {
    super.didUpdateWidget(oldWidget);
    if (oldWidget.target != widget.target) {
      // Save draft for old target before switching.
      if (oldWidget.onDraftChanged != null && _textCtl.text.isNotEmpty) {
        oldWidget.onDraftChanged!(_textCtl.text);
      }
      // Restore draft for new target.
      _textCtl.text = widget.restoredDraft ?? '';
      _lastRenderedTarget = null;
    }
  }
  @override
  void dispose() {
    // Emit the current draft so the parent can save it.
    if (widget.onDraftChanged != null && _textCtl.text.isNotEmpty) {
      widget.onDraftChanged!(_textCtl.text);
    }
    _textCtl.dispose();
    _scrollCtl.dispose();
    super.dispose();
  }
 ```
 Remove the existing `dispose` method (lines 1127-1132) — it's replaced by the new one above.
 - [ ] **Step 3: Thread draft callbacks through `ChatPanel`**
 Update `ChatPanel` to accept and pass through the new callbacks. Add fields:
 ```dart
  /// External draft text to restore in the chat detail view.
  final String? restoredDraft;
  /// Called when the draft text changes.
  final ValueChanged<String>? onDraftChanged;
 ```
 Pass them through in `build()` where `ChatDetailView` is constructed (line 58):
 ```dart
        child: ChatDetailView(
          messages: messages,
          snapshot: snapshot,
          target: target,
          clientName: clientName,
          currentChannelId: currentChannelId,
          channelName: channelName,
          onTs3ServerLink: onTs3ServerLink,
          restoredDraft: restoredDraft,
          onDraftChanged: onDraftChanged,
          messageMaxWidth: 500,
          headerTrailing: IconButton(
            tooltip: 'Close chat',
            icon: const Icon(Icons.close),
            onPressed: onClose,
          ),
        ),
 ```
 - [ ] **Step 4: Wire draft callbacks in `main.dart`**
 In the `ChatPanel(...)` constructor around line 2567, add the draft callbacks:
 ```dart
                              ChatPanel(
                                messages: _chatMessages,
                                snapshot: _snapshot!,
                                target: inlineChatTarget,
                                clientName: _inlineChatClientName,
                                onTs3ServerLink: _onTs3ServerLink,
                                restoredDraft: _chatDrafts[_draftKeyForTarget(inlineChatTarget)],
                                onDraftChanged: (text) {
                                  _chatDrafts[_draftKeyForTarget(_inlineChatTarget!)] = text;
                                },
                                onClose: _closeInlineChat,
                              ),
 ```
 - [ ] **Step 5: Complete `_saveCurrentDraft` in `main.dart`**
 The `_saveCurrentDraft` method is called from `_onOpenChat` (before switching) and `_closeInlineChat`. Since `ChatDetailView` emits drafts via `onDraftChanged` and `dispose`, the parent always has the latest draft in `_chatDrafts`. The method body stays as a no-op safety net:
 ```dart
  void _saveCurrentDraft() {
    // Drafts are continuously saved via onDraftChanged callback.
    // This method exists as an explicit save point for any future
    // snapshot-based draft capture.
  }
 ```
 - [ ] **Step 6: Run `flutter analyze`**
 Run: `cd apps/chanora_flutter && flutter analyze`
 Expected: No new errors
 - [ ] **Step 7: Commit**
 ```bash
 git add apps/chanora_flutter/lib/widgets/chat_views.dart apps/chanora_flutter/lib/widgets/chat_panel.dart apps/chanora_flutter/lib/main.dart
 git commit -m "feat(chat): per-target draft persistence with save/restore on switch"
 ```

 ### Task 5: Add unread dot indicator to channel tiles in `SnapshotView`
 **Files:**
 - Modify: `apps/chanora_flutter/lib/widgets/snapshot_view.dart` (add unread indicator)
 - Modify: `apps/chanora_flutter/lib/main.dart` (pass unread channel set)
 - [ ] **Step 1: Add unread channel IDs parameter to `SnapshotView`**
 Add a new required field to `SnapshotView` (after `canJoinVoiceChannel` around line 57):
 ```dart
  /// Set of channel IDs that have unread chat messages.
  final Set<BigInt> unreadChannelIds;
 ```
 - [ ] **Step 2: Add unread dot to `_channelTile`**
 In `_channelTile`, inside the `Row` children (after the channel name `Expanded` widget, around line 273), add an unread dot:
 ```dart
            // Unread indicator.
            if (widget.unreadChannelIds.contains(channel.id)) ...[
              const SizedBox(width: 8),
              Container(
                width: 8,
                height: 8,
                decoration: BoxDecoration(
                  color: theme.colorScheme.primary,
                  shape: BoxShape.circle,
                ),
              ),
            ],
 ```
 This must come before the password lock icon check (line 274).
 - [ ] **Step 3: Compute unread channel set in `main.dart`**
 Add a getter in `_BetaHomeState` that computes which channels have unread messages:
 ```dart
  /// Channel IDs that have unread chat messages (used for dot indicators).
  Set<BigInt> get _unreadChannelIds {
    if (_chatOpen) return const {};
    final ids = <BigInt>{};
    for (final entry in _chatMessages) {
      if (!entry.countsTowardUnread || entry.isSelf) continue;
      if (entry.target case rust.BridgeMessageTarget_Channel(:final id)) {
        ids.add(id);
      }
    }
    return ids;
  }
 ```
 - [ ] **Step 4: Pass unread channel set to `SnapshotView`**
 In the `SnapshotView(...)` constructor around line 2512, add:
 ```dart
                        unreadChannelIds: _unreadChannelIds,
 ```
 - [ ] **Step 5: Run `flutter analyze`**
 Run: `cd apps/chanora_flutter && flutter analyze`
 Expected: No new errors
 - [ ] **Step 6: Commit**
 ```bash
 git add apps/chanora_flutter/lib/widgets/snapshot_view.dart apps/chanora_flutter/lib/main.dart
 git commit -m "feat(chat): unread dot indicator on channel tiles with unread messages"
 ```
 ---
 ### Task 6: End-to-end verification
 **Files:** All modified files.
 - [ ] **Step 1: Run `flutter analyze` on the full project**
 Run: `cd apps/chanora_flutter && flutter analyze`
 Expected: Zero issues
 - [ ] **Step 2: Run `flutter test`**
 Run: `cd apps/chanora_flutter && flutter test`
 Expected: All tests pass (same baseline as before — 180 passed, 2 skipped)
 - [ ] **Step 3: Build macOS release**
 Run: `bash tools/build-macos.sh`
 Expected: Successful build producing `chanora-v0.2.0-beta.1-macos-aarch64.zip`
 - [ ] **Step 4: Manual QA checklist**
 Launch the app and verify:
 1. **Channel → chat switching**: With window ≥1024dp and chat panel open showing Server chat, click a channel in the tree. The chat panel should switch to that channel's chat (messages filter to that channel). Voice join should also happen.
 2. **Channel right-click → Chat**: Right-click a channel → "Open chat". Chat panel should switch to that channel's chat without joining voice.
 3. **Header chat button toggle**: With chat panel open showing a DM, click the header chat button. It should switch to the current voice channel's chat.
 4. **Draft persistence**: Type "hello" in chat input but don't send. Click a different channel. Type "world" in that channel's chat. Switch back to the first channel. The input should show "hello".
 5. **Close and reopen**: Close the chat panel. Click the header chat button. It should reopen to the last conversation with the draft intact.
 6. **Unread dots**: Close the chat panel. Have someone send a message to a specific channel. That channel in the tree should show a blue dot.
 7. **Medium/compact unchanged**: Narrow the window below 1024dp. Open chat. It should still push a full-screen route as before. No regressions.
 8. **DM switching still works**: Right-click a client → "Direct Message". Chat panel should switch to that DM. Right-click another client → "Direct Message". Should switch again.

 ## Self-Review
 ### Spec coverage
 | Requirement | Task |
 |---|---|
 | Channel → chat switching (tap) | Task 2 (wiring) + Task 3 (target resolution) |
 | Channel → chat (context menu) | Task 1 |
 | Header button switches when open | Task 3 |
 | Per-target draft persistence | Task 4 |
 | Close = dismiss (remember state) | Task 3 |
 | Unread dot on channels | Task 5 |
 | Medium/compact unchanged | No changes to those paths |
 ### Placeholder scan
 No TBD, TODO, or placeholder steps found. All code blocks contain complete implementations.
 ### Type consistency
 - `BridgeMessageTarget.channel(id)` uses `BigInt` — matches `channel.id` type
 - `_chatDrafts` uses `String` keys from `_draftKeyForTarget` — consistent
 - `onOpenChannelChat` callback type `ValueChanged<rust.BridgeChannel>?` — matches widget pattern
 - `unreadChannelIds` uses `Set<BigInt>` — matches channel ID type

 # Core Internal Split Implementation Plan
 > **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
 **Goal:** Improve `chanora_core` maintainability by moving stable event DTOs and network diagnostic state out of the oversized `lib.rs` while preserving the public crate Interface.
 **Architecture:** Keep `lib.rs` as the public Interface and session orchestration entry point. Move event-facing DTOs to `events.rs` and private network diagnostic ring-buffer state to `network_diagnostics.rs`; re-export public event types from `lib.rs` so downstream callers keep using `chanora_core::SessionEvent` and related names unchanged.
 **Tech Stack:** Rust 2021, Tokio broadcast/watch channels, `thiserror`, existing Cargo workspace tests.
 ---
 ### Task 1: Move Core Event DTOs
 **Files:**
 - Create: `core/chanora_core/src/events.rs`
 - Modify: `core/chanora_core/src/lib.rs`
 - Verify: `cargo test -p chanora_core`
 - [ ] **Step 1: Preserve current public Interface with tests**
 Run: `cargo test -p chanora_core`
 Expected: PASS. Existing bridge-facing tests and compile checks prove the current public event names are valid.
 - [ ] **Step 2: Create `events.rs` with the moved public event DTOs**
 Move these exact public types from `lib.rs` to `events.rs`:
 - `PttDescriptorSnapshot`
 - `PersistedPttBinding`
 - `SessionEvent`
 - `VoiceJoinSyncState`
 - `VoiceJoinErrorCode`
 - `NetworkState`
 Use local imports in `events.rs` for `chanora_audio::{AudioRoute, PttBackendDescriptor}` and `chanora_protocol::MessageTarget`.
 - [ ] **Step 3: Re-export moved types from `lib.rs`**
 Add `mod events;` and `pub use events::{...};` for all moved public types. Remove the original definitions from `lib.rs`.
 - [ ] **Step 4: Run tests**
 Run: `cargo test -p chanora_core`
 Expected: PASS with no public Interface break.
 ### Task 2: Move Core Network Diagnostics State
 **Files:**
 - Create: `core/chanora_core/src/network_diagnostics.rs`
 - Modify: `core/chanora_core/src/lib.rs`
 - Verify: `cargo test -p chanora_core network_diagnostics`
 - [ ] **Step 1: Move `NetworkDiagnostics` into a private module**
 Move the private `NetworkDiagnostics` struct and its methods from `lib.rs` into `network_diagnostics.rs`. Keep methods `pub(crate)` because `ChanoraSession` records connection/loss events and exports summaries.
 - [ ] **Step 2: Move the regression test with the module**
 Move `network_diagnostics_keeps_last_eight_loss_reasons` from the `lib.rs` test module into `network_diagnostics.rs` so the behaviour test lives next to the Implementation it protects.
 - [ ] **Step 3: Import the private module from `lib.rs`**
 Add `mod network_diagnostics;` and `use network_diagnostics::NetworkDiagnostics;`. Remove `VecDeque` from the `lib.rs` imports.
 - [ ] **Step 4: Run targeted and workspace verification**
 Run: `cargo test -p chanora_core network_diagnostics`
 Expected: PASS.
 Run: `cargo test --workspace`
 Expected: PASS.
 ### Task 3: Format and Check Workspace
 **Files:**
 - Modify: Rust files touched above only, except existing formatter-only churn may remain from prior `cargo fmt --all`.
 - [ ] **Step 1: Format Rust code**
 Run: `cargo fmt --all`
 Expected: no command output.
 - [ ] **Step 2: Compile workspace**
 Run: `cargo check --workspace`
 Expected: finishes successfully.
 - [ ] **Step 3: Inspect diff**
 Run: `git diff --stat`
 Expected: new `events.rs` and `network_diagnostics.rs`; smaller `core/chanora_core/src/lib.rs`; no public API renames.

 Self-review: This plan covers the recommended Core split first slice, avoids public Interface changes, has no placeholders, and keeps testing tied to the moved Implementations.

 # Maintainability Continuation Implementation Plan
 > **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
 **Goal:** Continue the current maintainability review with safe simplifications, full code-review remediation, current documentation, explicit fail-safe evidence, and Android runtime verification status.
 **Current status:** Task 0 and the audio-realtime portion of Task 0.1 have landed in commits `d835394` and `8606eb4`. Task 0.2 is a documentation/status alignment slice only; it must not claim Android or iOS runtime success.
 **Architecture:** Treat the existing uncommitted maintainability changes as the baseline slice. Fix safety and hidden-bug findings before broad Module splits. Preserve public Rust Core, Bridge, Protocol, Audio, and Flutter responsibilities while applying only tested simplifications and risk-reducing refactors. Record larger seam decisions as follow-up findings unless a huge Module must be split to make a safety fix testable.
 **Tech Stack:** Rust 2021 Cargo workspace, Flutter/Dart 3.11, Flutter Rust Bridge 2.12, Android ADB, Markdown governance and verification documents.

 ## File Structure
 Implementation should keep the following responsibilities stable:
 - `core/chanora_core/src/lib.rs`: public Core API, session orchestration, public re-exports, and integration-facing methods.
 - `core/chanora_core/src/events.rs`: Core public event DTOs re-exported by `lib.rs`.
 - `core/chanora_core/src/network_diagnostics.rs`: private bounded network diagnostic history and its local regression tests.
 - `crates/chanora_audio/src/voice_render.rs`: shared render/downmix helpers.
 - `crates/chanora_audio/src/ios_raw_unit.rs`, `ios_voice_unit.rs`, `android_voice_unit.rs`, `engine.rs`: platform/audio backends; avoid broad rewrites without device evidence.
 - `crates/chanora_audio/src/ptt_backends/mod.rs`: PTT backend descriptor and error definitions.
 - `crates/chanora_state/src/lib.rs`: snapshot reducers and state deltas.
 - `crates/chanora_protocol/src/adapter.rs`: protocol adapter event ordering and DTO projection.
 - `crates/chanora_bridge/src/api.rs`: bridge-facing API and DTO mapping; generated files are not manually edited.
 - `crates/chanora_diagnostics/src/lib.rs`: bounded diagnostics, redaction, and export data.
 - `docs/governance/maintainability-review-2026-06-08.md`: working review record and fail-safe gap log.
 - `docs/governance/document-index.md`: navigation index for review records.
 - `docs/architecture/sad.md`, `docs/architecture/sdd.md`: architecture updates for seams and implementation boundaries.
 - `docs/implementation-status-2026-05-28.md`: implementation status updates.
 - `docs/verification/swe4-unit-verification-plan.md`, `docs/verification/swe5-software-integration-verification-plan.md`: verification evidence and requirements updates.
 ## Review Findings To Remediate First
 The full review added these priority fixes before the original maintainability cleanup sequence:
 - Flutter privacy fail-safe: talk-power recovery must not clear a user/manual mute. Fixed in commit `d835394`.
 - Flutter stuck-transmit fail-safe: touch PTT must release when disposed while held. Fixed in commit `d835394`.
 - Flutter/iOS fail-safe: iOS audio-session activation errors must be caught, and activation should be moved before Rust VoiceProcessingIO startup where the current app flow allows. Missing-plugin/error hardening fixed in commit `d835394`; iOS device runtime verification remains required.
 - Rust realtime safety: Android and iOS raw render-reference buffers must not use unsynchronized mutable aliasing. Callback-path hardening fixed in commit `8606eb4`; the full lock-free `AudioHandler` / config / debug-recorder redesign remains a follow-up.
 - Rust realtime safety: Android input callback must not block on a mutex, and non-48 kHz capture should not allocate/clone per callback. Focused callback-path hardening fixed in commit `8606eb4`; Android target compilation and runtime verification remain blocked locally until the missing NDK compiler and an authorized ADB target are available.
 - Rust control-plane safety: disconnect and protocol control requests must remain bounded under broken transport or sustained voice traffic.
 - Governance correctness: README/release/VAD/Android API/product-decision docs must not contradict code or verification status.
 ## Task 0: Fix Flutter Privacy and Stuck-Transmit Fail-Safes
 **Files:**
 - Modify: `apps/chanora_flutter/lib/main.dart`
 - Modify: `apps/chanora_flutter/lib/widgets/voice_compact.dart`
 - Modify: `apps/chanora_flutter/lib/services/ios_audio_session_controller.dart`
 - Test: `apps/chanora_flutter/test/widgets/voice_compact_test.dart`
 - Test: existing Flutter tests under `apps/chanora_flutter/test/`
 - [ ] **Step 1: Add failing touch PTT disposal regression test**
 Create or update `apps/chanora_flutter/test/widgets/voice_compact_test.dart` with a widget test that presses the touch PTT button, replaces the widget without sending pointer-up, and expects the callback sequence `[true, false]`.
 - [ ] **Step 2: Run touch PTT test and verify RED**
 Run from `apps/chanora_flutter`: `flutter test test/widgets/voice_compact_test.dart`
 Expected before production fix: FAIL because disposal does not emit `false`.
 - [ ] **Step 3: Implement touch PTT release-on-dispose**
 Add `dispose()` to the touch PTT button state so an active press calls `widget.onHeldChanged(false)` exactly once before disposal.
 - [ ] **Step 4: Run touch PTT test and verify GREEN**
 Run from `apps/chanora_flutter`: `flutter test test/widgets/voice_compact_test.dart`
 Expected after fix: PASS.
 - [ ] **Step 5: Add or preserve mute-owner regression coverage**
 If an existing pure reducer seam is available, add a failing test for manual mute true -> talk power blocked -> talk power restored. If no testable seam exists, first extract the smallest voice mute owner helper from `main.dart` and test it directly.
 - [ ] **Step 6: Implement independent mute owners**
 Ensure talk-power recovery clears only the talk-power owner and does not clear manual/user mute or permission mute. Effective hard mute is the OR of manual, permission, and talk-power owners.
 - [ ] **Step 7: Harden iOS audio-session controller errors**
 Add tests for `MissingPluginException` in `ios_audio_session_controller_test.dart`, then catch `MissingPluginException` or `Object` so activation/deactivation failures do not become unhandled async errors.
 - [ ] **Step 8: Run focused Flutter verification**
 Run from `apps/chanora_flutter`: `flutter test test/widgets/voice_compact_test.dart test/services/ios_audio_session_controller_test.dart && flutter analyze`
 Expected: PASS.
 - [ ] **Step 9: Commit Flutter fail-safe slice**
 Run:
 ```bash
 git add apps/chanora_flutter/lib/main.dart apps/chanora_flutter/lib/widgets/voice_compact.dart apps/chanora_flutter/lib/services/ios_audio_session_controller.dart apps/chanora_flutter/test/widgets/voice_compact_test.dart apps/chanora_flutter/test/services/ios_audio_session_controller_test.dart
 git commit -m "fix(voice): preserve mute owners and release touch ptt"
 ```
 Expected: one commit containing only Flutter fail-safe fixes and tests.
 ## Task 0.1: Fix Rust Realtime and Control-Plane Safety Findings
 **Files:**
 - Modify: `crates/chanora_audio/src/android_voice_unit.rs`
 - Modify: `crates/chanora_audio/src/ios_raw_unit.rs`
 - Modify: `crates/chanora_audio/src/engine.rs`
 - Modify: `crates/chanora_protocol/src/adapter.rs`
 - Modify: `core/chanora_core/src/lib.rs`
 - Test: Rust tests in affected crates
 - [ ] **Step 1: Add failing bounded-buffer regression for render-reference handoff**
 Add host-testable unit coverage around the render-reference buffer behavior so a writer can publish a frame and a reader can read a complete latest frame without unsynchronized mutation.
 - [ ] **Step 2: Replace unsafe shared mutable render-reference buffers**
 Replace unsynchronized mutable aliasing in Android and iOS raw render-reference buffers with a realtime-safe handoff such as an `ArrayQueue` of complete frames or a documented atomic double-buffer. Do not add mutex locking to realtime callbacks.
 - [ ] **Step 3: Add failing protocol progress regression where feasible**
 Add or isolate a test proving control requests are not starved by sustained voice packet drain.
 - [ ] **Step 4: Bound voice draining and disconnect shutdown**
 Cap voice packet draining per protocol loop and make disconnect/shutdown bounded so UI/Core locks are not held across unbounded transport waits.
 - [ ] **Step 5: Run focused Rust verification**
 Run: `cargo test -p chanora_audio -p chanora_protocol -p chanora_core`
 Expected: PASS.
 - [ ] **Step 6: Commit Rust safety slice**
 Run:
 ```bash
 git add crates/chanora_audio/src/android_voice_unit.rs crates/chanora_audio/src/ios_raw_unit.rs crates/chanora_audio/src/engine.rs crates/chanora_protocol/src/adapter.rs core/chanora_core/src/lib.rs
 git commit -m "fix(audio): harden realtime and protocol fail-safes"
 ```
 Expected: one commit containing only Rust safety fixes and tests.

 - [ ] **Step 5: Commit plan/spec/governance alignment slice**
 Skipped in this subagent run because the instruction for Task 0.2 explicitly says not to commit.
 Run:
 ```bash
 git add docs/superpowers/specs/2026-06-08-maintainability-continuation-design.md docs/superpowers/plans/2026-06-08-maintainability-continuation.md docs/governance/maintainability-review-2026-06-08.md README.md CHANGELOG.md docs/governance/product-decision-register.md docs/release/release-readiness-go-nogo-record.md docs/release/dv-waiver-register.md docs/verification/verification-master-plan.md docs/verification/sys4-system-integration-verification-plan.md
 git commit -m "docs: align review findings and verification gates"
 ```
 Expected: one documentation/governance commit, with unavailable optional files omitted only if unchanged.
 ## Task 1: Verify Current Branch Baseline
 **Files:**
 - Read: `docs/governance/maintainability-review-2026-06-08.md`
 - Read: `docs/superpowers/plans/2026-06-08-core-internal-split.md`
 - Inspect: all currently modified files from `git status --short`
 - Modify: none unless verification exposes a small mechanical fix
 - [ ] **Step 1: Inspect current status**
 Run: `git status --short`
 Expected: output includes the existing maintainability branch changes and no staged files from unrelated work.
 - [ ] **Step 2: Inspect current diff summary**
 Run: `git diff --stat`
 Expected: diff remains focused on Core split, Audio simplifications, State/Protocol/Bridge/Diagnostics cleanup, and documentation updates.
 - [ ] **Step 3: Verify Rust formatting**
 Run: `cargo fmt --all --check`
 Expected: PASS with no output. If it fails, run `cargo fmt --all`, inspect the resulting diff, and include formatter-only changes in the smallest relevant commit.
 - [ ] **Step 4: Verify Rust compilation**
 Run: `cargo check --workspace`
 Expected: PASS for the full workspace.
 - [ ] **Step 5: Verify Rust tests**
 Run: `cargo test --workspace`
 Expected: PASS for the full workspace.
 - [ ] **Step 6: Verify Flutter analysis**
 Run from `apps/chanora_flutter`: `flutter analyze`
 Expected: PASS with no new analyzer errors.
 - [ ] **Step 7: Verify Flutter tests**
 Run from `apps/chanora_flutter`: `flutter test --exclude-tags e2e`
 Expected: PASS for non-e2e Flutter tests.
 - [ ] **Step 8: Check Android device availability**
 Run: `adb devices -l`
 Expected if a target is connected: at least one `device` row. Expected if no target is connected: only the header and no `device` row; record Android runtime verification as blocked in `docs/governance/maintainability-review-2026-06-08.md`.
 - [ ] **Step 9: Commit verified existing slice**
 Only after Steps 1-8 have been completed or any blocked Android status has been documented, stage the smallest coherent existing slice.
 Recommended first slice if tests pass:
 ```bash
 git add core/chanora_core/src/lib.rs core/chanora_core/src/events.rs core/chanora_core/src/network_diagnostics.rs docs/superpowers/plans/2026-06-08-core-internal-split.md
 git commit -m "refactor(core): split event and diagnostics internals"
 ```
 Expected: one commit containing only the Core split and its plan.
 ## Task 2: Commit Existing Built-In and Helper Reuse Simplifications
 **Files:**
 - Modify or stage: `crates/chanora_audio/src/ptt_backends/mod.rs`
 - Modify or stage: `crates/chanora_audio/src/voice_render.rs`
 - Modify or stage: `crates/chanora_audio/src/ios_raw_unit.rs`
 - Modify or stage: `crates/chanora_diagnostics/src/lib.rs`
 - Modify or stage: `crates/chanora_state/src/lib.rs`
 - Modify or stage: `crates/chanora_resolver/Cargo.toml`
 - Modify or stage: `Cargo.lock`
 - [ ] **Step 1: Inspect simplification diffs**
 Run:
 ```bash
 git diff -- crates/chanora_audio/src/ptt_backends/mod.rs crates/chanora_audio/src/voice_render.rs crates/chanora_audio/src/ios_raw_unit.rs crates/chanora_diagnostics/src/lib.rs crates/chanora_state/src/lib.rs crates/chanora_resolver/Cargo.toml Cargo.lock
 ```
 Expected: diffs show built-in/helper reuse only: `thiserror::Error`, `VecDeque`, render helper reuse, reducer reuse, and workspace metadata inheritance.
 - [ ] **Step 2: Run focused Rust tests for changed areas**
 Run: `cargo test -p chanora_audio -p chanora_diagnostics -p chanora_state -p chanora_resolver`
 Expected: PASS for all listed crates.
 - [ ] **Step 3: Run workspace Rust verification**
 Run: `cargo check --workspace && cargo test --workspace`
 Expected: PASS for workspace compile and tests.
 - [ ] **Step 4: Commit built-in/helper reuse slice**
 Run:
 ```bash
 git add crates/chanora_audio/src/ptt_backends/mod.rs crates/chanora_audio/src/voice_render.rs crates/chanora_audio/src/ios_raw_unit.rs crates/chanora_diagnostics/src/lib.rs crates/chanora_state/src/lib.rs crates/chanora_resolver/Cargo.toml Cargo.lock
 git commit -m "refactor: reuse built-ins and shared helpers"
 ```
 Expected: one commit containing only the built-in/helper reuse simplifications.
 ## Task 3: Review Remaining Audio Platform Diffs Before Committing
 **Files:**
 - Inspect: `crates/chanora_audio/src/android_voice_unit.rs`
 - Inspect: `crates/chanora_audio/src/engine.rs`
 - Inspect: `crates/chanora_audio/src/ios_voice_unit.rs`
 - Modify: `docs/governance/maintainability-review-2026-06-08.md` if Android runtime verification is blocked or audio fail-safe evidence changes
 - [ ] **Step 1: Inspect platform-audio diffs**
 Run:
 ```bash
 git diff -- crates/chanora_audio/src/android_voice_unit.rs crates/chanora_audio/src/engine.rs crates/chanora_audio/src/ios_voice_unit.rs
 ```
 Expected: diffs are understandable as local simplification or fail-safe improvements. If a diff changes platform runtime behavior and no Android/iOS device evidence is available, keep it separate from non-platform commits.
 - [ ] **Step 2: Run audio crate tests**
 Run: `cargo test -p chanora_audio`
 Expected: PASS.
 - [ ] **Step 3: Check Android runtime availability**
 Run: `adb devices -l`
 Expected if connected: at least one target row with `device`. Expected if blocked: no target row.
 - [ ] **Step 4: Run Android build when a target is available**
 Run from `apps/chanora_flutter`: `flutter build apk --debug`
 Expected: PASS and a debug APK is produced.
 - [ ] **Step 5: Run Android install and smoke when a target is available**
 Run from `apps/chanora_flutter`: `flutter install`
 Expected: PASS and app installs on the connected target.
 Manual smoke expectations:
 - App launches without crash.
 - Permission UI can be reached.
 - Audio device/permission screen does not crash.
 - Voice controls remain responsive.
 - [ ] **Step 6: Record blocked Android evidence if no target is available**
 Modify `docs/governance/maintainability-review-2026-06-08.md` Section 6 so it includes the exact `adb devices -l` result and states Android runtime verification is blocked until a device or emulator is connected.
 - [ ] **Step 7: Commit platform-audio slice**
 If Android runtime was verified, run:
 ```bash
 git add crates/chanora_audio/src/android_voice_unit.rs crates/chanora_audio/src/engine.rs crates/chanora_audio/src/ios_voice_unit.rs docs/governance/maintainability-review-2026-06-08.md
 git commit -m "refactor(audio): simplify platform voice internals"
 ```
 If Android runtime was blocked, run:
 ```bash
 git add crates/chanora_audio/src/android_voice_unit.rs crates/chanora_audio/src/engine.rs crates/chanora_audio/src/ios_voice_unit.rs docs/governance/maintainability-review-2026-06-08.md
 git commit -m "refactor(audio): simplify platform voice internals"
 ```
 Expected: commit message is the same, but the maintainability review explicitly records the blocked Android runtime evidence.
 ## Task 4: Review Protocol and Bridge Diffs as One Boundary Slice
 **Files:**
 - Inspect: `crates/chanora_protocol/src/adapter.rs`
 - Inspect: `crates/chanora_bridge/src/api.rs`
 - Modify: `docs/architecture/sad.md`
 - Modify: `docs/architecture/sdd.md`
 - Modify: `docs/governance/maintainability-review-2026-06-08.md`
 - [ ] **Step 1: Inspect protocol/bridge diffs**
 Run:
 ```bash
 git diff -- crates/chanora_protocol/src/adapter.rs crates/chanora_bridge/src/api.rs
 ```
 Expected: diffs preserve protocol isolation and bridge DTO shape unless bridge generation and Flutter tests are included.
 - [ ] **Step 2: Verify protocol tests**
 Run: `cargo test -p chanora_protocol`
 Expected: PASS.
 - [ ] **Step 3: Verify bridge tests and compile**
 Run: `cargo test -p chanora_bridge`
 Expected: PASS.
 - [ ] **Step 4: Verify Flutter after bridge/API changes**
 Run from `apps/chanora_flutter`: `flutter analyze && flutter test --exclude-tags e2e`
 Expected: PASS for analyzer and non-e2e tests.
 - [ ] **Step 5: Document seam findings**
 Update `docs/governance/maintainability-review-2026-06-08.md` so remaining bridge DTO drift and protocol voice packet seam risks are listed under fail-safe gaps or follow-up opportunities.
 - [ ] **Step 6: Update architecture docs if seam wording changed**
 If the code diff clarifies protocol/bridge boundaries, update `docs/architecture/sad.md` and `docs/architecture/sdd.md` with one concise note each. The note should state whether protocol voice packet handling is an intentional exception and whether bridge DTO mirrors remain required by Flutter Rust Bridge.
 - [ ] **Step 7: Commit protocol/bridge slice**
 Run:
 ```bash
 git add crates/chanora_protocol/src/adapter.rs crates/chanora_bridge/src/api.rs docs/architecture/sad.md docs/architecture/sdd.md docs/governance/maintainability-review-2026-06-08.md
 git commit -m "refactor: clarify protocol bridge boundaries"
 ```
 Expected: one commit for protocol/bridge boundary cleanup plus matching architecture documentation.
 ## Task 5: Run a Second-Pass Simplification Search
 **Files:**
 - Inspect: Rust and Dart source files only
 - Modify: only if the simplification is mechanical, local, and covered by tests
 - Modify: `docs/governance/maintainability-review-2026-06-08.md`
 - [ ] **Step 1: Search for custom queue front removal**
 Run: `rg "remove\(0\)|removeAt\(0\)" core crates apps/chanora_flutter/lib apps/chanora_flutter/test`
 Expected: no results. If results exist, replace with `VecDeque` in Rust or a clearer Dart queue structure only when behavior is covered by a local test.
 - [ ] **Step 2: Search for manual Rust error formatting**
 Run: `rg "impl (std::fmt::)?Display for .*Error|impl std::error::Error for" core crates`
 Expected: only intentional manual implementations remain. For simple enum error types, replace with `thiserror::Error` and add or preserve tests for user-facing strings.
 - [ ] **Step 3: Search for duplicate mono downmix loops**
 Run: `rg "chunks_exact\(2\)|downmix|mono" crates/chanora_audio/src`
 Expected: duplicate i16/f32 mono downmix code is either absent or justified. If a duplicate remains, route it through an existing helper and run `cargo test -p chanora_audio`.
 - [ ] **Step 4: Search for shallow modules worth documenting**
 Run: `rg "^pub struct|^pub enum|^pub fn|^fn" crates/chanora_audio/src/processor crates/chanora_prefetch/src crates/chanora_resolver/src core/chanora_core/src`
 Expected: identify candidates, but do not merge modules in this task. Record speculative merges in `docs/governance/maintainability-review-2026-06-08.md` unless a candidate is trivial and already covered by tests.
 - [ ] **Step 5: Commit second-pass mechanical simplifications if any**
 If code changed, run the relevant focused tests plus `cargo check --workspace && cargo test --workspace`, then inspect the changed files:
 ```bash
 git status --short
 ```
 Stage only the files changed by the second-pass mechanical simplification. Example for a Rust-only diagnostics simplification:
 ```bash
 git add crates/chanora_diagnostics/src/lib.rs docs/governance/maintainability-review-2026-06-08.md
 git commit -m "refactor: apply second-pass mechanical simplifications"
 ```
 Expected: commit contains only local mechanical simplifications and the review record.
 - [ ] **Step 6: Commit review-only findings if no code changed**
 If no code changed and only findings were added, run:
 ```bash
 git add docs/governance/maintainability-review-2026-06-08.md
 git commit -m "docs: record maintainability follow-up findings"
 ```
 Expected: documentation-only commit.
 ## Task 6: Final Documentation Alignment
 **Files:**
 - Modify: `docs/governance/maintainability-review-2026-06-08.md`
 - Modify: `docs/governance/document-index.md`
 - Modify: `docs/implementation-status-2026-05-28.md`
 - Modify: `docs/verification/swe4-unit-verification-plan.md`
 - Modify: `docs/verification/swe5-software-integration-verification-plan.md`
 - Modify if needed: `docs/architecture/sad.md`
 - Modify if needed: `docs/architecture/sdd.md`
 - [ ] **Step 1: Update maintainability review completion status**
 Edit `docs/governance/maintainability-review-2026-06-08.md` so these sections are current:
 - Changes applied
 - Remaining simplification opportunities
 - Fail-safe gaps that need evidence
 - Verification policy
 - Android ADB status
 - Git policy
 - [ ] **Step 2: Update document index**
 Ensure `docs/governance/document-index.md` includes `docs/governance/maintainability-review-2026-06-08.md` and this plan/spec if the repository convention indexes superpowers documents.
 - [ ] **Step 3: Update implementation status**
 Ensure `docs/implementation-status-2026-05-28.md` describes maintainability review results without claiming production readiness.
 - [ ] **Step 4: Update SWE.4 verification plan**
 Ensure `docs/verification/swe4-unit-verification-plan.md` lists Rust unit verification expectations for Core, Audio, State, Protocol, Bridge, Diagnostics, Resolver, and Prefetch when those crates are touched.
 - [ ] **Step 5: Update SWE.5 verification plan**
 Ensure `docs/verification/swe5-software-integration-verification-plan.md` lists integration expectations for Bridge DTO drift, protocol event folding, Flutter analyze/test, and Android runtime smoke evidence.
 - [ ] **Step 6: Run documentation cross-link search**
 Run: `rg "maintainability-review-2026-06-08|core-internal-split|maintainability-continuation" docs README.md`
 Expected: references point to existing files and no stale path is introduced.
 - [ ] **Step 7: Commit final documentation alignment**
 Run:
 ```bash
 git add docs/governance/maintainability-review-2026-06-08.md docs/governance/document-index.md docs/implementation-status-2026-05-28.md docs/verification/swe4-unit-verification-plan.md docs/verification/swe5-software-integration-verification-plan.md docs/architecture/sad.md docs/architecture/sdd.md
 git commit -m "docs: align maintainability verification records"
 ```
 Expected: one documentation-focused commit.
 ## Task 7: Final Verification and Android Evidence
 **Files:**
 - Modify: `docs/governance/maintainability-review-2026-06-08.md` only if final verification status changes
 - [ ] **Step 1: Run full Rust verification**
 Run: `cargo fmt --all --check && cargo check --workspace && cargo test --workspace`
 Expected: PASS.
 - [ ] **Step 2: Run full Flutter verification**
 Run from `apps/chanora_flutter`: `flutter analyze && flutter test --exclude-tags e2e`
 Expected: PASS.
 - [ ] **Step 3: Run ADB check**
 Run: `adb devices -l`
 Expected if connected: at least one target row with `device`. Expected if blocked: no target row and the maintainability review states Android runtime verification is blocked.
 - [ ] **Step 4: Run Android build/install/smoke when connected**
 Run from `apps/chanora_flutter`: `flutter build apk --debug && flutter install`
 Expected: PASS. Manually verify app launch, permission screen access, audio settings access, and voice control responsiveness.
 - [ ] **Step 5: Commit final verification evidence if docs changed**
 If the maintainability review was updated with final verification evidence, run:
 ```bash
 git add docs/governance/maintainability-review-2026-06-08.md
 git commit -m "docs: record maintainability verification evidence"
 ```
 Expected: one small evidence-only documentation commit.
 - [ ] **Step 6: Inspect final history and status**
 Run: `git status --short && git log --oneline -10`
 Expected: no unexpected unstaged changes related to this work; recent commits are small and logically separated.
 ---
 ## Self-Review
 Spec coverage:
 - Safe simplifications are covered by Tasks 1, 2, 3, 4, and 5.
 - Built-in replacement opportunities are covered by Tasks 2 and 5.
 - Fail-safe gaps are covered by Tasks 3, 4, 6, and 7.
 - Rust, Flutter, and Android verification are covered by Tasks 1 and 7, with focused verification in Tasks 2 through 4.
 - Documentation updates are covered by Tasks 4, 6, and 7.
 - Small commit policy is covered by every task's dedicated commit step.
 Placeholder scan: The plan contains no open placeholders. Task 5 uses `git status --short` before staging because the exact second-pass files are only known after the search runs; the example command shows the required staging style.
 Type consistency: The plan does not introduce new APIs or types. It preserves current crate and file boundaries from the approved design.

 # Chanora Adaptive 3-Panel Layout Design
 **Date:** 2026-06-05
 **Status:** Draft
 **Scope:** Desktop adaptive layout for ≥1024dp three-panel mode, centralized breakpoint system, and chat panel integration.
 ---
 ## 1. Problem Statement
 Chanora's current responsive layout uses a single breakpoint (`_wideBreakpoint = 600dp`) scattered across 9 files in 8 duplicatable clusters (5 `LayoutBuilder` sites, 7 `MediaQuery.sizeOf` sites). The desktop layout is a 2-panel split (VoiceBar 320px + SnapshotView flex) with no persistent chat surface.
 Research across Discord, Mattermost, Rocket.Chat, Element, and hardware resolution data shows:
 - **1024dp** is the industry-standard threshold where a third panel becomes viable (Discord member list, Mattermost RHS, Rocket.Chat contextual bar all use this value).
 - At 1024dp, Chanora's math works: `320 + 12 + 300 + 12 + 380 = 1024` — minimum viable for VoicePanel + ChannelTree + ChatPanel.
 - Production apps use **push/replace navigation** for chat on constrained widths, reserving persistent panels for ≥1024dp.
 - Centralized breakpoint logic is standard practice (Rocket.Chat `LayoutProvider`, Mattermost `WindowSizes`).
 ## 2. Design Decisions
 | Decision | Choice | Rationale |
 |---|---|---|
 | 3-panel activation threshold | **1024dp** | Industry consensus (Discord, Mattermost, Rocket.Chat). Chanora math: center pane = 300dp minimum. |
 | Chat behavior at 600–1023dp | **Push route (unchanged)** | Research validates current pattern. Overlays are for contextual info, not primary conversation. |
 | Chat behavior at ≥1024dp | **Inline panel** | Chat renders in a 380dp right panel alongside the channel tree. No route push. |
 | Centralized breakpoints | **New `ChanoraBreakpoints` + `ViewportInfo`** | Replaces 8 duplicated responsive clusters with single source of truth. |
 | Architecture approach | **Adaptive Scaffold Shell** | Extends existing widget tree with centralized layout logic. Not a full rewrite. |
 | AdaptiveScaffold package | **Not used** | Package discontinued (flutter/flutter#162965). Manual layout gives better control for voice-first UX. |
 ## 3. Breakpoint System
 ### 3.1 Layout Classes
 Three tiers, aligned with Material 3 adaptive guidance:
 | Class | Width Range | Primary Behavior |
 |---|---|---|
 | `compact` | < 600dp | Single column. VoiceStatusChip at bottom. Chat as pushed route. |
 | `medium` | 600–1023dp | 2-panel row (VoicePanel 320px + SnapshotView flex). Chat as pushed route. |
 | `expanded` | ≥ 1024dp | 3-panel row (VoicePanel 320px + SnapshotView flex + ChatPanel 380px). Chat inline. |
 ### 3.2 New Files
 **`lib/design/breakpoints.dart`** — canonical breakpoint tokens:
 ```dart
 class ChanoraBreakpoints {
  static const double compact = 0;
  static const double medium = 600;
  static const double expanded = 1024;
  static const double voicePanelWidth = 320;
  static const double chatPanelWidth = 380;
  static const double panelGap = 12;
 }
 enum LayoutClass { compact, medium, expanded }
 LayoutClass layoutClassFromWidth(double width) {
  if (width >= ChanoraBreakpoints.expanded) return LayoutClass.expanded;
  if (width >= ChanoraBreakpoints.medium) return LayoutClass.medium;
  return LayoutClass.compact;
 }
 ```
 **`lib/design/viewport_info.dart`** — inherited widget that computes layout class once per frame:
 ```dart
 class ViewportInfo extends InheritedWidget {
  const ViewportInfo({
    super.key,
    required this.layoutClass,
    required this.width,
    required this.height,
    required super.child,
  });
  final LayoutClass layoutClass;
  final double width;
  final double height;
  static ViewportInfo of(BuildContext context) {
    final info = context.dependOnInheritedWidgetOfExactType<ViewportInfo>();
    assert(info != null, 'No ViewportInfo found in widget tree');
    return info!;
  }
  bool get isCompact => layoutClass == LayoutClass.compact;
  bool get isMedium => layoutClass == LayoutClass.medium;
  bool get isExpanded => layoutClass == LayoutClass.expanded;
  @override
  bool updateShouldNotify(ViewportInfo old) =>
      layoutClass != old.layoutClass ||
      width != old.width ||
      height != old.height;
 }
 ```
 ### 3.3 What This Replaces
 The audit identified these duplicatable clusters that get consolidated:
 | Cluster | Current Locations | Replacement |
 |---|---|---|
 | 600dp breakpoint (×3) | `main.dart:304,2280,2468` | `ChanoraBreakpoints.medium` |
 | 400px cap (×2) | `connect_widgets.dart`, `voice_settings.dart` | Named token in `ChanoraBreakpoints` |
 | 72% modal height (×2) | `audio_output_tile.dart`, `ptt_capability_badge.dart` | Named token |
 | 320px voice bar width | `main.dart:2467` | `ChanoraBreakpoints.voicePanelWidth` |
 | Platform capability branching | `voice_settings.dart`, `voice_compact.dart`, `audio_processing_config_state.dart` | Centralized capability helper |
 ## 4. Adaptive Shell
 ### 4.1 Widget Tree
 The existing `_BetaHome` widget tree is restructured to use `ViewportInfo`:
 ```
 _BetaHome
  ├─ macOS: Scaffold with traffic-light padding (unchanged)
  ├─ Mobile: ChanoraMobileScaffold (unchanged)
  └─ bodyContent:
       └─ LayoutBuilder
            └─ ViewportInfo (computes layoutClass from constraints)
                 ├─ compact:  Column [SnapshotView, VoiceStatusChip, PTT]
                 ├─ medium:   Row [VoicePanel, SnapshotView]
                 └─ expanded: Row [VoicePanel, SnapshotView, ChatPanel]
 ```
 `AdaptiveShell` is a pure layout widget — it reads `ViewportInfo` and composes the appropriate children. All state remains in `_BetaHome`.
 ### 4.2 Platform Handling
 Platform-specific scaffolding stays at the top level, unchanged:
 - **macOS**: `Scaffold` with `_macOSTrafficLightPad` top padding (28dp)
 - **Mobile**: `ChanoraMobileScaffold` with compact idle chrome
 - **Windows/Linux**: Default `Scaffold`
 The `ViewportInfo` + layout switch only affects the body content inside the scaffold.
 ## 5. Chat Panel Behavior
 ### 5.1 Compact (< 600dp)
 No change. Chat opens as a pushed `MaterialPageRoute`:
 ```
 main.dart:_onOpenChat → Navigator.push(ChatPage)
 ```
 Channel tree is fully replaced. Back button returns to main view.
 ### 5.2 Medium (600–1023dp)
 Same as compact. Chat is a pushed route. The 2-panel layout (VoicePanel + SnapshotView) stays as the home screen.
 ### 5.3 Expanded (≥ 1024dp)
 Chat renders inline in a 380dp right panel. The flow:
 1. User taps "Open Text Chat" on a client, or taps the chat badge
 2. `_onOpenChat` reads `ViewportInfo.of(context).isExpanded`
 3. If expanded: sets `_inlineChatTarget` state → `ChatPanel` renders in the third column
 4. If not expanded: pushes `ChatPage` route (unchanged behavior)
 ### 5.4 ChatPanel Widget
 New widget for ≥1024dp only:
 ```
 ChatPanel (380dp fixed width)
  ├─ Header: target name + close button
  ├─ Message list (scrollable, max-width ~500dp for readability)
  └─ Input field
 ```
 **State sharing:** The `_chatMessages` list and `_chatFeedRevision` listenable in `_BetaHome` already track all messages. `ChatPanel` reads from the same source — no duplication.
 **Close behavior:** User taps close button → `_inlineChatTarget` set to null → `ChatPanel` removed from tree.
 ### 5.5 Width Transition
 When the user resizes from ≥1024dp to <1024dp while chat is open inline:
 1. `ChatPanel` disappears (it's only in the expanded layout branch)
 2. A brief snackbar appears: "Tap the chat button to continue your conversation"
 3. The `_inlineChatTarget` state is preserved — tapping the chat button reopens the pushed `ChatPage` route with the same target
 This matches Discord's behavior when the member list collapses on resize.
 ## 6. Panel Sizing
 | Element | Width | Behavior |
 |---|---|---|
 | VoicePanel (left) | 320dp fixed | VoiceBar, connection status, PTT controls. Unchanged. |
 | Panel gaps | 12dp | Between each panel. Unchanged. |
 | SnapshotView (center) | flex (1fr) | Grows to fill remaining space. |
 | ChatPanel (right) | 380dp fixed | Only rendered at ≥1024dp. |
 | Chat messages | max-width ~500dp | Centered within ChatPanel for readability. |
 | macOS traffic light pad | 28dp top | Unchanged. Only affects height. |
 **Center pane widths at common viewports:**
 | Viewport | Center Width | Feel |
 |---|---|---|
 | 1024dp | 300dp | Minimum viable (matches Discord at same width) |
 | 1200dp | 476dp | Comfortable |
 | 1280dp | 556dp | Spacious (Chanora's default window size) |
 | 1440dp | 716dp | Very spacious |
 | 1920dp | 1184dp | Ultra-wide — consider capping center max-width post-MVP |
 ## 7. Migration Map
 | File | Change | Scope |
 |---|---|---|
 | `lib/design/breakpoints.dart` | **New** — breakpoint tokens + `LayoutClass` enum | New file |
 | `lib/design/viewport_info.dart` | **New** — `ViewportInfo` inherited widget | New file |
 | `lib/main.dart` | Replace `_wideBreakpoint = 600.0` with `ChanoraBreakpoints.medium`. Wrap body in `ViewportInfo`. Add `_inlineChatTarget` state. Branch `_onOpenChat` for expanded vs compact/medium. Add `ChatPanel` to expanded Row. | Significant |
 | `lib/widgets/chat_views.dart` | Replace `_chatMobileBreakpoint` with `ChanoraBreakpoints.medium`. No structural changes. | Token swap |
 | `lib/widgets/connect_widgets.dart` | Replace hardcoded 400px with token. | Token swap |
 | `lib/widgets/app_snack_bar.dart` | Replace hardcoded 600/560px with tokens. | Token swap |
 | `lib/widgets/snapshot_view.dart` | No changes. Local spacer math stays local. | None |
 | `lib/widgets/voice_compact.dart` | Replace platform branching with centralized helper (optional, post-MVP). | Optional |
 **Unchanged:** macOS scaffold, ChanoraMobileScaffold, all voice controls, channel tree, chat route for compact/medium, all Rust bridge code.
 ## 8. Hardware Coverage
 The 1024dp threshold coverage based on 2026 resolution data:
 | Setup | Logical Width | Sees 3-Panel? |
 |---|---|---|
 | 1920×1080 @100% fullscreen | 1920dp | Yes |
 | 1920×1080 @125% fullscreen | 1536dp | Yes |
 | 1920×1080 @150% fullscreen | 1280dp | Yes |
 | 1366×768 @100% fullscreen | 1366dp | Yes |
 | 1366×768 @125% fullscreen | 1093dp | Yes |
 | 1366×768 @125% windowed (~85%) | ~930dp | No (2-panel) |
 | 2560×1440 @100% half-screen | ~1280dp | Yes |
 | 2560×1440 @125% half-screen | ~1024dp | Yes (edge) |
 | MacBook 13" Split View | ~708dp | No (2-panel) |
 | MacBook 14" Split View | ~744dp | No (2-panel) |
 | MacBook 16" Split View | ~852dp | No (2-panel) |
 Chanora's default window (1280×720 on Windows/Linux) starts in 3-panel mode immediately.
 ## 9. Out of Scope (Post-MVP)
 - Resizable panels (drag-to-resize VoicePanel/ChatPanel width)
 - NavigationRail for ultra-wide monitors
 - ChatPanel showing user profile or channel info
 - Center pane max-width cap for ultra-wide monitors
 - Centralized platform capability helper (consolidating voice_settings/voice_compact/audio_processing branching)
 - Animated transitions between layout classes
 - ChatPanel as a sheet/drawer on medium widths

 # Maintainability Continuation Design
 **Date:** 2026-06-08
 **Status:** Approved design for implementation and full code-review remediation; Task 0 and focused audio-realtime fixes landed, documentation/governance alignment in progress
 **Scope:** Continue the current working-branch maintainability pass, add full code-review findings, and fix high-risk bugs before broad rewrites.
 ## Purpose
 This design continues the project review already present in the working tree. The goal is to simplify the project where changes are low-risk, testable, and documented, while avoiding speculative architecture churn.
 The work covers unnecessary functions, structs, files, modules, duplicated custom implementations, built-in replacement opportunities, outdated documents, fail-safe gaps, Android runtime verification requirements, and full code-review remediation for hidden bugs.
 ## Recommended Approach
 Use a targeted continuation of the current maintainability pass, now ordered by safety risk.
 The existing branch already contains a first slice of simplification: core event DTO extraction, network diagnostics locality, `VecDeque` queue improvements, derived PTT backend errors, render downmix helper reuse, state reducer reuse, workspace metadata cleanup, and documentation updates. This design treats those changes as the baseline, but the full review found privacy, realtime-audio, disconnect, and documentation-governance issues that take priority over cosmetic simplification.
 The remediation order is:
 - Privacy and stuck-transmit fail-safes in Flutter voice state. Fixed in commit `d835394`.
 - iOS audio-session error hardening before Rust VoiceProcessingIO startup. Missing-plugin/error handling fixed in commit `d835394`; iOS device runtime verification remains required.
 - Rust realtime audio safety, especially unsynchronized render-reference buffers and blocking/allocating callbacks. Focused callback-path hardening fixed in commit `8606eb4`; full lock-free `AudioHandler` / config / debug-recorder redesign remains a follow-up.
 - Bounded disconnect/control-plane progress in Rust protocol/core. Pending unless later code-review evidence closes it.
 - Documentation and release/governance contradictions that can cause wrong verification claims. Addressed by Task 0.2 documentation alignment.
 - Larger Module splits after behavior is protected by tests.
 Rejected alternatives:
 - Documentation-only audit: safer, but leaves clear simplifications unimplemented.
 - Broad architectural cleanup: may produce long-term wins, but is too risky for this pass because bridge, protocol, audio, and Android behavior have high regression cost.
 ## Architecture Boundaries
 The existing responsibilities remain intact:
 - Flutter owns presentation, navigation, Material 3 behavior, accessibility, localization presentation, and platform UI behavior.
 - Flutter Rust Bridge owns typed DTO/API glue and generated bindings.
 - Rust Core owns session orchestration, cross-crate coordination, bridge-facing public events, and stable public APIs.
 - Protocol owns TeamSpeak-compatible protocol isolation behind `tsclientlib`.
 - Audio owns capture, render, processing, PTT backends, platform audio behavior, and voice packet handling where explicitly documented.
 - Diagnostics owns redaction, logs, export records, and bounded diagnostic history.
 Public interfaces should stay stable unless a change clearly removes duplicated or unnecessary code and has direct verification.
 ## Review Targets
 The implementation review should inspect these areas first:
 - `core/chanora_core/src/lib.rs`, `events.rs`, `network_diagnostics.rs`, and `ptt.rs`
 - `crates/chanora_audio`, especially duplicated render, capture, PTT, and platform-audio helpers
 - `crates/chanora_state` reducer paths
 - `crates/chanora_protocol` adapter ordering, event, and DTO mapping paths
 - `crates/chanora_bridge/src/api.rs`, excluding generated bridge files unless regeneration is intentionally part of a change
 - `crates/chanora_diagnostics/src/lib.rs`
 - `crates/chanora_prefetch` and `crates/chanora_resolver` as a documented follow-up seam decision unless a trivial cleanup appears
 - `apps/chanora_flutter/lib`, excluding generated localization and bridge files unless an API change requires updates
 - governance, architecture, implementation-status, and verification documents affected by the code review
 Full code-review remediation targets:
 - `apps/chanora_flutter/lib/main.dart`: mute ownership, iOS audio-session preflight, chat/unread follow-ups, and oversized session-controller extraction candidates.
 - `apps/chanora_flutter/lib/widgets/voice_compact.dart`: touch PTT release-on-dispose fail-safe.
 - `apps/chanora_flutter/lib/services/ios_audio_session_controller.dart`: missing-plugin fail-safe handling.
 - `apps/chanora_flutter/lib/services/audio_lifecycle_service.dart`: macOS route/default-device no-op documentation or future adapter seam.
 - `crates/chanora_audio/src/android_voice_unit.rs`, `ios_raw_unit.rs`, `ios_voice_unit.rs`, and `engine.rs`: realtime callback safety and platform lifecycle rollback.
 - `core/chanora_core/src/lib.rs` and `crates/chanora_protocol/src/adapter.rs`: bounded disconnect and control-plane progress under voice load.
 - `README.md`, `CHANGELOG.md`, `docs/release/*`, `docs/verification/*`, and `docs/governance/product-decision-register.md`: stale platform, release, VAD, Android runtime, and decision-register claims.
 ## Simplification Rules
 Every code change must satisfy these rules:
 - Prefer deletion, built-in APIs, derives, or reuse of existing helpers over new abstractions.
 - Merge files or modules only when the merged unit has a clearer single responsibility.
 - Split files only when it improves locality around a stable responsibility and preserves public API shape.
 - Do not manually edit generated files unless the generation process is part of the verified change.
 - Do not introduce backward-compatibility shims unless there is a persisted-data, shipped-API, external-consumer, or explicit product need.
 - Record larger architectural opportunities in the maintainability review instead of forcing them into this pass.
 Full code-review fix rules:
 - Fix safety bugs before Module split work.
 - Use test-driven development for production behavior changes: write the failing test, run it, implement the minimal fix, then rerun the test.
 - Keep manual/generated bridge files out of direct edits unless regeneration is intentionally verified.
 - Split huge Modules only when the split creates a deeper Module with leverage and locality; file-size-only sharding is not sufficient.
 - Compare architecture choices against established voice/chat client practice: Mumble-style bounded voice/control separation, Discord/TeamSpeak-style independent mute owners, WebRTC-style realtime callback minimalism, and Matrix/Element-style coherent state replication.
 ## Testing Design
 Verification is tied to change type:
 - Rust-only changes require `cargo fmt --all`, `cargo check --workspace`, and `cargo test --workspace`.
 - Flutter changes require `flutter analyze` and `flutter test --exclude-tags e2e` from `apps/chanora_flutter`.
 - Bridge DTO/API changes require Rust verification, bridge generation check, Flutter analyze, and Flutter tests.
 - Android platform, permission, lifecycle, or audio changes require Rust and Flutter verification plus Android NDK target compilation, `adb devices -l`, Android build/install, and a device or emulator smoke test.
 - Documentation-only changes require affected docs and cross-links to be read and checked; code tests are not required unless the docs describe a code change just made.
 If no ADB target is connected, Android runtime verification must be recorded as blocked. If Android target compilation cannot find the NDK compiler, for example `aarch64-linux-android-clang`, Android build evidence must also be recorded as blocked. The implementation must not claim Android runtime success without build/install/smoke evidence from an authorized device or emulator.
 ## Fail-Safe Review
 The review must identify fail-safe gaps and either verify them, fix them, or record the missing evidence.
 Priority fail-safe areas:
 - User mute ownership must not be cleared by talk-power or permission recovery.
 - Touch and keyboard PTT must release on cancellation, disposal, disconnect, lifecycle transition, or missed-up conditions.
 - iOS AVAudioSession must be configured and activated before VoiceProcessingIO startup.
 - Realtime callbacks must not block, allocate repeatedly, or use unsynchronized mutable aliasing.
 - Disconnect and control requests must be bounded and must not hold global session locks across unbounded transport waits.
 - Android and iOS device runtime behavior must be verified on hardware or an authorized emulator/simulator where applicable before platform success is claimed.
 - Android secure storage and Keystore-backed data-encryption-key handling
 - Android permission and audio lifecycle behavior
 - Stuck PTT prevention and missed-key-up recovery
 - Diagnostic redaction and privacy-sensitive event export
 - Bridge DTO drift between Core, Bridge, and Dart generated bindings
 - Protocol isolation exceptions for voice packet handling
 - Runtime behavior gaps not covered by unit tests
 No release-readiness or production-safety claim should be made without matching evidence.
 ## Documentation Design
 The working review record remains `docs/governance/maintainability-review-2026-06-08.md`.
 Documents to update when affected:
 - `README.md`
 - `CHANGELOG.md`
 - `docs/governance/document-index.md`
 - `docs/governance/product-decision-register.md`
 - `docs/architecture/sad.md`
 - `docs/architecture/sdd.md`
 - `docs/implementation-status-2026-05-28.md`
 - `docs/verification/swe4-unit-verification-plan.md`
 - `docs/verification/swe5-software-integration-verification-plan.md`
 - `docs/verification/verification-master-plan.md`
 - `docs/verification/sys4-system-integration-verification-plan.md`
 - `docs/release/release-readiness-go-nogo-record.md`
 - `docs/release/dv-waiver-register.md`
 - release or fail-safe records if verification status changes
 Documentation should distinguish completed changes, follow-up opportunities, blocked verification, and release limitations.
 ## Commit Policy
 No commit is created automatically. A commit happens only when explicitly requested, after inspecting `git status`, `git diff`, and recent commits.
 ## Success Criteria
 This work is successful when:
 - Safe simplifications are implemented or recorded as follow-up opportunities.
 - Built-in replacement opportunities are applied only when behavior remains covered by tests.
 - Fail-safe gaps are documented with required evidence or fixed with verification.
 - Rust and Flutter verification are run as required by the touched files, including targeted regression tests for every fixed bug.
 - Android ADB runtime verification is run when a target is available or explicitly recorded as blocked.
 - Documents reflect the final code and verification state.
 - Full code-review findings are either fixed, downgraded with evidence, or recorded as follow-up risks with verification requirements.

 | 0.9.10 | 2026-05-18 | Authorized Option B of the benchmark-infrastructure decision for the realtime audio path. Added SysRS-307 (maintained numeric performance baselines for the realtime audio capture and playback paths — heap allocation count per callback after warmup, per-callback wall-clock budget relative to the audio frame period, Opus encode/decode latency, and resampler throughput at common rate-pair conversions; extends SysRS-180/SysRS-181 from prescriptive intent into a measurable contract; consistent with SysRS-186 and SysRS-236). Added SysRS-308 (advisory CI regression reporting executing the benchmark suite on every PR and every merge to the default branch on at least one host architecture, surfacing results in the PR status-check view; explicitly **advisory only** — does not fail the build, does not block merge; escalation to a build-failing hard gate is out of scope and deferred to a future SysRS clause after baseline maturity; consistent with the SysRS-234..239 verification-family pattern). Added SysRS-309 (explicitly declared numeric tolerance window for the advisory comparison; numeric value(s) and comparison methodology delegated to SysDes/SAD; suggested starting value +20% recorded as non-binding downstream guidance). All three new clauses are consistent with SysRS-295 (no automatic telemetry / diagnostic upload in MVP) — they neither authorize nor require off-device transmission of measurement data beyond the existing CI provider surface visible to repository collaborators. Explicitly **NOT** authored in this update: (a) Dimension 3 production telemetry export of timing histograms (deferred to P1; any future opt-in performance-evidence export through the user-initiated diagnostic-export path requires a separate P1 SysRS clause and must be reconciled with SysRS-295 at that time); (b) build-failing hard CI gate (deferred to a future SysRS clause). |

 Android integration changes require a working Android target toolchain and a connected device or emulator. The minimum local gate is:
 1. The Android NDK compiler needed by the target build, including `aarch64-linux-android-clang` for arm64, is available.
 2. `adb devices -l` shows one authorized target.
 3. Android app builds for that target.
 4. The app installs and launches.
 5. Permission, connect-screen, audio-start/stop, and diagnostic-export smoke paths are exercised or explicitly marked not applicable to the change.
 If the NDK compiler is unavailable or no target is connected and authorized, Android verification is blocked rather than passed.
