+- Tests already existed in `src/summary.test.ts` with comprehensive coverage (8 tests, 8 expect() calls) - likely created during `add-summary-generator` implementation
+- Existing tests cover all key scenarios: phase name extraction, max 5 words truncation, task ID fallback, special characters handling, ultimate "plan" fallback, empty content, multiple phases (first one used), and numbers in phase names
+- All tests pass - no additional tests needed as the coverage is already comprehensive
+- Pattern: when implementing a module (like `add-summary-generator`), it's valuable to write tests alongside the implementation rather than deferring to a separate test task - this leads to better coverage and faster feedback loops

-
-
-
-## mock-loop-interface
-
-- Created `src/agent.ts` with an `Agent` interface that defines `run()` and `isAvailable()` methods
-- The interface uses typed events (`onLog`, `onOutput`) for streaming updates to consumers
-- `LogEntry` has categories: info, success, warning, error - matches the existing loop.ts color scheme
-- `AgentOutput` is raw text with timestamps for agent stdout/stderr
-- `OpenCodeAgent` wraps the real CLI using `Bun.spawn()` to capture output streams
-- `MockAgent` is fully configurable: logs, output, exitCode, delay, and availability
-- For tests, use `!` non-null assertions when accessing array elements after verifying length with `toHaveLength()`
-- The mock can be reconfigured mid-test using `configure()` method for testing different scenarios
-- Keep test mocks simple - just arrays of strings and basic config objects, no complex simulation
-
-## loop-dry-run
-
-- Added `dryRun` and `agent` options to `LoopOptions` interface
-- When `dryRun: true`, the loop skips git branch creation and uses MockAgent instead of OpenCodeAgent
-- The `agent` option allows injecting any Agent implementation for testing or custom behavior
-- Replaced `process.exit(1)` calls with `throw new Error()` for better testability
-- Tests need `pauseSeconds: 0` to avoid the 3-second default pause between iterations
-- TASKS.md format uses `###` (h3) for task IDs, not `##` (h2) - important for test fixtures
-- When testing agent invocation, need pending tasks - if all tasks complete, loop exits before calling agent
-- Event callbacks (onLog, onOutput) forward agent events to the loop's console.log and stdout
-
-## output-buffer
-
-- Created `src/ui/buffer.ts` as a shared module for storing loop logs and agent output separately
-- Reused the `LogCategory` type from `src/agent.ts` to keep categories consistent (info, success, warning, error)
-- Used callback-based subscriptions with `Set` for efficient add/remove operations
-- Subscription functions return an unsubscribe function (closure pattern) for clean cleanup
-- `getLogs()` and `getOutput()` return copies of arrays (`[...array]`) to prevent external mutation
-- The `clear()` method was added for buffer reset while keeping subscriptions intact
-- Tests verify that subscriptions continue working after clear() - important for reconnection scenarios
-- Kept the module simple with no dependencies beyond the LogCategory type - YAGNI principle
-
-## stream-capture
-
-- Added `buffer?: OutputBuffer` to `LoopOptions` - optional so non-UI mode continues to work unchanged
-- Used a factory function pattern `createLoggers(buffer?)` to create log functions that write to both console and buffer
-- The loggers are created at the start of `runLoop` and passed to `createWorkingBranch` via a `Loggers` interface
-- Agent output is captured in the `onOutput` event handler: writes to both `process.stdout` and `buffer?.appendOutput()`
-- The optional chaining (`buffer?.appendLog`) ensures graceful fallback when no buffer is provided
-- Console.log calls continue working for non-UI mode - the buffer is purely additive
-- Tests mock both `console.log` and `process.stdout.write` to verify output goes to both destinations
-- Buffer subscriptions work in real-time - subscribers receive entries as they are appended during loop execution
-
-## bun-server
-
-- Bun.serve() returns a server object with inferred type - no need to import `Server` type explicitly (it requires a generic argument anyway)
-- For WebSocket upgrade, use `server.upgrade(req, { data })` inside fetch handler - if successful returns truthy and you return `undefined`
-- `routes` object handles static routes, `fetch` function handles dynamic routes and WebSocket upgrades
-- WebSocket handlers receive `ServerWebSocket` where T is the data type attached during upgrade
-- For tests, use different ports per test to avoid conflicts (8315, 8316, etc.) since tests may run in parallel
-- `afterEach` with `server.stop()` ensures clean teardown between tests
-- WebSocket tests need proper timeout handling with Promise wrappers around event callbacks
-- Placeholder responses are simple - just return `new Response()` with appropriate headers/status
-
-## websocket-streaming
-
-- WebSocket data can hold unsubscribe functions directly - `{ id, unsubscribeLogs: (() => void) | null, unsubscribeOutput: (() => void) | null }`
-- When a client connects: (1) send connected message, (2) send history, (3) subscribe to buffer updates
-- History message includes both logs and output in a single `{ type: "history", logs: [], output: [] }` message
-- New entries are sent as individual `{ type: "log", entry }` or `{ type: "output", entry }` messages
-- On disconnect, must call the unsubscribe functions and set them to null to avoid memory leaks
-- Tests for WebSocket message timing can be flaky - avoid sequential `await receiveMessage()` calls across multiple sockets
-- Better pattern: collect all messages in arrays via `onmessage` handlers, then filter and assert after a small delay
-- Exported `WebSocketMessage` type for type-safe parsing in tests and future frontend code
-- The `BufferLogEntry` and `BufferAgentOutput` types needed to be imported from buffer.ts for the message types
-
-## html-shell
-
-- Bun's HTML imports allow `./app.tsx` to be referenced directly in script tags - Bun handles the transpilation automatically
-- Used `
