- Add Pause/Resume toggle to session context menu
- Gray agent dots when parent session is paused
- Disable input field with 'Session paused' placeholder when paused
- Preserve focus on prompt input during tree rebuilds
- Add per-agent statewait streams to track execution state
- Agent dots show: green=idle, orange=calling, blue=thinking
- Session dots show RPC connection health (unchanged)
- Use version counter pattern to force QML binding re-evaluation
Session selection now auto-selects first agent:
- Clicking a session row selects its first agent (not just the session)
- Auto-select at startup now picks first agent of first session
- Fixes issue where clicking session would clear agent and show empty chat
Improved UI feedback:
- Header shows 'Session / Agent' name instead of just state
- State indicator gray when no agent selected
- Placeholder message when no agent selected: 'Select an agent to view chat'
- Chat ListView hidden when no agent (shows placeholder instead)
- Input already disabled with 'No agent' placeholder (existing behavior)
Cleanup:
- Remove dead declaration reconcileAgentConnections(const QVariantList&)
Change createAgent to return error string (empty=success).
Replace standardButtons with custom footer so dialog stays open
on error, showing the message and letting the user adjust values.
Connection monitoring and all 9P operations now use immutable
session/agent UUIDs in paths instead of mutable display names.
The server resolves these via the new Aliases mechanism in findChild.
This fixes the disconnected-indicator bug after session rename:
connections no longer go stale when names change.
Removed dead sessionNameForId/agentNameForId helpers and the
m_agentConnectionPaths tracking (unnecessary with stable paths).
Rename operations no longer restart streams.
- Introduce StreamFsm class wrapping QProcess lifecycle with
Oneshot/Looping/Guarded restart policies
- Replace raw QProcess management in Ollie9pClient with StreamFsm
- Fix chatblockmodel FSM to properly handle [[[end]]] and fence
transitions with a combined State enum (Outside/InBlock/InFence)
- Add Q_INVOKABLE to setActiveSessionId for direct QML access
- Add streamfsm.cpp to CMakeLists.txt for both KF5 and KF6 builds
- Add killSession(sessionId) Q_INVOKABLE to Ollie9pClient
- Accept right button in session tree MouseArea
- Context menu with Kill option on right-click
- MenuItem resolves session ID via parent chain
- New session dialog: Backend and Model now use proper ComboBoxes with
editable=true so users can type or select from dropdown
- Backend picker and model picker dialogs removed (no longer needed)
- Model list populated reactively via Connections on backend selection
- Fix model caching: m_rootModels[be].toStringList() returns a copy;
extract to local QStringList, append, store back into map
- Session creation uses correct path 'session/new' instead of 'new'
- Chat blocks are now collapsible: user/assistant/tool expanded by default,
reasoning/call/error/info/default collapsed
- Fix chat history on session switch: readLogForSession() reads from the
explicit session/agent path instead of relying on active state
- Fix delegate layout: use plain ColumnLayout instead of Item-wrapped
ColumnLayout so ListView calculates implicit heights correctly
- Add C++ methods: loadRootBackends(), loadRootAgents(), getAvailableModels(), createSession()
- Add Q_PROPERTYs for root data state (backends, agents, models)
- Add '+' button to sessions toolbar
- Create New Session Dialog with:
- Directory field + Browse button (FolderDialog)
- Name field (optional, auto-generated if empty)
- Backend combo (populated from /backends)
- Model combo (filtered by selected backend)
- Agent combo (populated from /agents)
- Remote field (user@host:port)
- Root data loaded lazily on startup
- OK creates session via 'write new' 9P call and refreshes list
- Add getAgents() to Ollie9pClient for listing agents per session
- Add switchAgent() for switching sessions+agents atomically
- Add activeAgentId property and activeAgentIdChanged signal
- Replace flat ListView with tree-aware model (session → agents)
- Session nodes expandable/collapsible with ▶/▼ indicator
- Agent nodes indented, clickable to activate that agent
- Active agent highlighted, active session auto-expanded
- State dots on both session and agent rows
Kill the entire D-Bus rendering pipeline. The GUI now uses plan9port's
9p command as a subprocess for all server communication:
- Chat streaming: persistent 'read chat' process, readyReadStandardOutput
delivers tokens directly to QML (no polling, no signals, no offsets)
- State: 'read statewait' process, restarts on each state change
- Session list: 'read session/idx' one-shot
- Submit/stop/kill: 'write prompt/ctl' one-shot
The QML is stripped to fundamentals: session list + monospace streaming
text (last 8KB tail) + input field. No ChatBlockModel, no ThemeManager,
no OllieDBusClient, no syntax highlighting, no markdown rendering.
This eliminates the multi-second GUI freezes caused by:
- QTextDocument relayout on 200KB+ accumulated text
- loadEarlier cascade creating hundreds of delegates
- KSyntaxHighlighting::Repository blocking init
- Offset mismatch triggering synchronous D-Bus calls
Features will be re-added incrementally on this proven foundation.
D-Bus retained only for plasmoid/tray/KRunner (desktop integration).
