+Build a **performant, robust native Android app** (Kotlin + Compose) that lets you use pi sessions running on your laptop from anywhere (bed, outside, etc.) via **Tailscale**, **without SSH/SFTP**. + +Primary success criteria: +- Smooth long chats with streaming output (no visible jank) +- Safe/resilient remote connection over tailnet +- Fast session browsing and resume across multiple projects/cwds +- Clear extension path for missing capabilities + +--- + +## 1) Facts from pi docs (non-negotiable constraints) + +### 1.1 RPC transport model +From `docs/rpc.md`: +- RPC is **JSON lines over stdin/stdout** of `pi --mode rpc` +- It is **not** a native TCP/WebSocket protocol + +Implication: +- Android cannot connect directly to RPC over network. +- You need a **laptop-side bridge** process: + - Android ↔ (Tailscale) ↔ Bridge ↔ pi RPC stdin/stdout + +### 1.2 Sessions and cwd +From `docs/session.md`, `docs/sdk.md`: +- Session files include a `cwd` in header and are stored under `~/.pi/agent/sessions/----/...jsonl` +- RPC has `switch_session`, but tools are created with process cwd context + +Implication: +- Multi-project correctness should be handled by **one pi process per cwd** (managed by bridge). + +### 1.3 Session discovery +From `docs/rpc.md`: +- No RPC command exists to list all session files globally. + +Implication: +- Bridge should read session files locally and expose a bridge API (best approach). + +### 1.4 Extension UI in RPC mode +From `docs/rpc.md` and `docs/extensions.md`: +- `extension_ui_request` / `extension_ui_response` must be supported for dialog flows (`select`, `confirm`, `input`, `editor`) +- Fire-and-forget UI methods (`notify`, `setStatus`, `setWidget`, `setTitle`, `set_editor_text`) are also emitted + +Implication: +- Android client must handle extension UI protocol end-to-end. + +--- + +## 2) Architecture decision + +## 2.1 Connection topology +- **Laptop** runs: + - `pi-bridge` service (WebSocket server) + - one or more `pi --mode rpc` subprocesses +- **Phone** runs Android app with WebSocket transport +- Network is Tailscale-only, no router forwarding + +## 2.2 Bridge protocol (explicit) +Use an **envelope protocol** over WS to avoid collisions between bridge-control operations and raw pi RPC messages. + +Example envelope: +```json +{ "channel": "bridge", "payload": { "type": "bridge_list_sessions" } } +{ "channel": "rpc", "payload": { "type": "prompt", "message": "hi" } } +``` + +Responses/events: +```json +{ "channel": "bridge", "payload": { "type": "bridge_sessions", "sessions": [] } } +{ "channel": "rpc", "payload": { "type": "message_update", ... } } +``` + +Why explicit envelope: +- Prevent ambiguous parsing +- Keep protocol extensible +- Easier debugging and telemetry + +## 2.3 Process management +Bridge owns a `PiProcessManager` keyed by cwd: +- `getOrStart(cwd)` +- idle TTL eviction +- crash restart policy +- single writer lock per cwd/session + +## 2.4 Session indexing +Bridge scans `~/.pi/agent/sessions/` and returns: +- `sessionPath`, `cwd`, `createdAt`, `updatedAt` +- `displayName` (latest `session_info.name`) +- `firstUserMessagePreview` +- optional `messageCount`, `lastModel` + +Android caches this index per host and refreshes incrementally. + +--- + +## 3) UX scope (v1) + +1. **Hosts**: add/edit host (tailscale host/ip, port, token,

model + thinking cycling +4. **Extension UI**: dialog requests + fire-and-forget requests +5. **Settings**: defaults and diagnostics + +--- + +## 4) Performance-first requirements (explicit budgets) + +These are required, not optional: + +### 4.1 Latency budgets +- Cold app start to visible cached sessions: **< 1.5s** target, **< 2.5s** max (mid-range device) +- Resume session to first rendered messages: **< 1.0s** target for cached metadata +- Prompt send to first token (healthy LAN/tailnet): **< 1.2s** target + +### 4.2 Rendering budgets +- Chat streaming should keep main thread frame time mostly under 16ms +- No sustained jank while streaming > 5 minutes +- Tool outputs default collapsed when large + +### 4.3 Memory budgets +- No unbounded string accumulation in UI layer +- Streaming buffers bounded and compacted +- Long chat (>= 2k messages including tool events) should avoid OOM and GC thrash + +### 4.4 Throughput/backpressure +- WS inbound processing must not block UI thread +- Throttled rendering (e.g., 20–40ms update interval) +- Drop/coalesce non-critical transient updates when overwhelmed + +### 4.5 Reconnect/resync behavior +After disconnect/reconnect: +- restore active

Buffer drops non-critical events when full to prevent memory exhaustion during high-frequency streaming. Add StreamingBufferManager for memory-efficient text streaming with: - Per-message 50KB content limit (tail truncation) - Automatic segment compaction - LRU eviction for oldest messages - Memory usage estimation Add BackpressureEventProcessor for event coalescing and prioritization: - Critical events prioritized (stream lifecycle, UI requests) - Non-critical deltas coalesced under backpressure - Unified ProcessedEvent sealed interface for UI consumption Add TurnStartEvent and TurnEndEvent to RpcIncomingMessage hierarchy for complete lifecycle tracking. Add coroutines dependency to core-rpc for Flow-based backpressure. All components include comprehensive unit tests.

Fix default port mismatch (8765 → 8787 in test) 2. Add connection diagnostics on Hosts screen: - New ConnectionDiagnostics class to test bridge connectivity - Tests WebSocket connection, auth, and get_state RPC - Shows status icons (success/failed/testing) per host - Displays model/cwd info on successful connection - Updated HostsScreen with Test button and result details 3. Extract SessionController into separate interface file: - SessionController.kt with all session control operations - ForkableMessage data class for fork picker - ModelInfo with all fields (id, name, provider, thinkingLevel) 4. Add fork-point picker support: - getForkMessages() in SessionController - forkSessionFromEntryId() for specific message forking - ForkFromEntry action in SessionsViewModel - loadForkMessages() for UI to fetch options 5. Add MetricsRecorder interface: - MetricsRecorder interface for testability - DefaultMetricsRecorder implementation - NoOpMetricsRecorder for tests - PerformanceMetrics now delegates to DefaultMetricsRecorder 6.

picker (Phase 3) Task 3.1 - Session Stats Display: - Add GetSessionStatsCommand and SessionStats data class - Add getSessionStats() to SessionController - Stats sheet showing token usage (input/output/cache) - Display total cost with 4 decimal precision - Show message counts (user/assistant/tool) - Copyable session file path - Stats button in chat header (bar chart icon) Task 3.2 - Model Picker: - Add GetAvailableModelsCommand and AvailableModel data class - Add SetModelCommand for setting specific model - Full model picker dialog with search functionality - Group models by provider - Show context window, thinking capability, costs - Long-press model chip to open picker - Tap to cycle models (existing behavior preserved) All quality gates pass: ktlintCheck, detekt, test,

2026 17:25:09 +0000 Subject: [PATCH 100/154] fix(sessions): make New Session work + add flat view toggle Fix 'New Session' button: - Was failing because it tried to call newSession() without an active connection - Now establishes connection first (like resume), then sends new_session command - Shows proper loading state and navigates to chat on success Add directory view toggle: - 'All' button shows flat list of all sessions sorted by updatedAt - 'Tree' button shows original hierarchical CWD view - Flat view shows CWD as label on each session card Refactor newSession() into smaller
