 ### Analysis/Retrospection for Attempt 19:
-*   **TypeScript Errors in `server.test.ts`**: The planned fixes for TS2493, TS2339, TS2707 were either not correctly applied or were insufficient. New TS errors (TS2367, TS2352, TS2358) emerged, primarily related to type assertions and checks within logger mock call argument validation. The `VitestMock` type usage for `findFreePortSpy` is still problematic.
+*   **TypeScript Errors in `server.test.ts`**: The applied fixes were insufficient. The `VitestMock` type usage for `findFreePortSpy` is still incorrect. The logger argument checks need more robust type guarding.
 *   **`index.test.ts` Failures**:
-    *   The `mockStartServer` issue persists. The top-level `vi.mock('./dist/lib/server.js', ...)` is not effectively mocking the `startServer` function when `dist/index.js` (the SUT) dynamically requires `dist/lib/server.js`. The SUT seems to get the original, unmocked version.
-    *   The `--port` test failure indicates `yargs` `apply` function isn't setting `process.env.HTTP_PORT` as expected in the test environment, or the assertion timing is off. The planned debug log for this was not confirmed as added/visible.
-    *   The `--json` test failure (unexpected logs) means `mockConsoleLog.mockClear()` was not added or was ineffective, and/or other `console.log` calls (like the debug ones) are interfering.
-*   **`server.test.ts` Timeouts**: The `startProxyServer` timeouts remain, suggesting the async nature of `http.createServer().listen()` or `findFreePort` interactions within these tests is still not correctly handled by the mocks.
+    *   `mockStartServer` not being called suggests the top-level `vi.mock('./dist/lib/server.js', ...)` is not effective for the dynamically imported SUT (`dist/index.js`).
+    *   `--port` test: The yargs `apply` function *is* setting `process.env.HTTP_PORT` correctly in the test's main process. The failure might be related to how `runMainWithArgs` executes or if `process.env` is being reset/overridden unexpectedly before the assertion.
+    *   `--json` test: `mockConsoleLog.mockClear()` is working, but the debug logs from `index.test.ts` itself (`[INDEX_TEST_DEBUG]`) and `index.ts` (`[INDEX_TS_DEBUG]`) are being captured.
+*   **`server.test.ts` Timeouts**: The `startProxyServer` timeouts persist, indicating issues with the `http.createServer().listen()` or `findFreePort` mocks within that suite.
 *   **Integration Test Failures**:
-    *   LLM Mocking: The `llm-provider` mock factory *is* being called. However, the `mockLLMProviderInstance.generateText.mockClear().mockResolvedValueOnce()` calls are not working. This could mean the `mockLLMProviderInstance` object itself is not the one the SUT (spawned server) is using, or the mock calls are being reset/overridden elsewhere. The `CODECOMPASS_INTEGRATION_TEST_MOCK_LLM` env var is present but not used by the read-only `llm-provider.ts`.
-    *   `get_session_history`: The "Repository path is required" error is gone, which is progress. However, "Query 2" (from `agent_query`) is still missing. This points to an issue in `addQuery` within `agent-service.ts` or how `processAgentQuery` interacts with session state. The planned `sessionId` logging was not confirmed as added/visible.
-    *   `trigger_repository_update`: `batchUpsertVectors` spy not called. This remains an issue with `indexRepository` or the qdrant mock.
+    *   LLM Mocking: The `llm-provider` mock factory is called, and `mockLLMProviderInstance` is returned. However, `mockLLMProviderInstance.generateText.mockClear().mockResolvedValueOnce()` is not effective. This strongly suggests the SUT (spawned server) is either getting a *different instance* of the LLM provider or the mock setup in the test's `beforeEach` is being overridden or not correctly applied to the instance the SUT uses.
+    *   `get_session_history`: The debug logs confirm `addQuery` *is* called for the second query by `agent-service.ts`. The fact that "Query 2" is missing from the final history output, despite `addQuery` being called, points to a potential issue in how `SessionState.queries` array is managed or how the `get_session_history` tool formats its output.
+    *   `trigger_repository_update`: `batchUpsertVectors` spy not called.
 
 ### Next Step / Plan for Next Attempt (Attempt 20):
 1.  **`src/tests/server.test.ts` TypeScript Errors (Highest Priority - 11 errors):**
-    *   **TS2707 (`VitestMock` generics)**: Change `VitestMock<[number], Promise<number>>` to `MockInstance<[number], Promise<number>>` for `findFreePortSpy` type, as `MockInstance` is the correct Vitest type for spies and takes the expected number of generic arguments.
+    *   **TS2707 (`VitestMock` generics)**: Change `VitestMock<[number], Promise<number>>` to `MockInstance<[number], Promise<number>>` for `findFreePortSpy`.
     *   **TS2493 (tuple length)** & **TS2352 (undefined conversion)**: For logger call assertions like `const meta = callArgs[1] as { message?: string };`, first check `callArgs && callArgs.length > 1 && callArgs[1] !== undefined && typeof callArgs[1] === 'object' && callArgs[1] !== null` before trying to access `message`.
     *   **TS2339 (`.includes` on `never`)**: For `firstArg.includes(...)`, ensure `firstArg` is explicitly checked `typeof firstArg === 'string'` before calling `.includes()`.
     *   **TS2358 (`instanceof` LHS) & TS2339 (`.message` on `never`)**: For `secondArg instanceof Error && secondArg.message.includes(...)`, ensure `secondArg` is first checked `typeof secondArg === 'object' && secondArg !== null` and then potentially cast to `Error` or use a type guard before accessing `message`.
     *   **TS2367 (unintentional comparison)**: For `if (firstArgString === "Failed to start CodeCompass")`, if `firstArgString` can be `""`, this comparison is valid. If TypeScript infers `firstArgString` as `""` incorrectly, the type inference leading to that needs to be fixed. For now, assume the comparison is intentional and the type inference is the issue to be addressed by other fixes.
 2.  **`src/tests/index.test.ts` Failures (20):**
     *   **`mockStartServer` not called**:
-        *   Modify `runMainWithArgs`: Instead of relying on top-level `vi.mock` for `dist/lib/server.js`, use `vi.doMock(MOCKED_SERVER_MODULE_PATH, () => ({ startServer: mockStartServer, ... }))` *inside* `runMainWithArgs` just before `await import(indexPath)`. This ensures the mock is in place for the dynamic import.
-        *   Ensure `MOCKED_SERVER_MODULE_PATH` correctly points to `'../../dist/lib/server.js'` relative to `index.test.ts` if `indexPath` is `dist/index.js`.
-    *   **`--port` test**: Add the `console.log` inside the `yargs` `.option('port', { apply: (value) => { ... } })` function in `src/index.ts` (as planned for A19) to see if it's called and what `process.env.HTTP_PORT` is.
-    *   **`--json` test**: Add `mockConsoleLog.mockClear()` immediately before `await runMainWithArgs(...)` in this specific test. Filter out the `[INDEX_TEST_DEBUG]` and `[INDEX_TS_DEBUG]` logs from the assertion if they are unavoidable.
+        *   Modify `runMainWithArgs`: Use `vi.doMock(MOCKED_SERVER_MODULE_PATH, () => ({ startServer: mockStartServer, startProxyServer: mockStartProxyServer, ServerStartupError: ServerStartupError }))` *inside* `runMainWithArgs` just before `await import(indexPath)`. This ensures the mock is in place for the dynamic import of `dist/index.js`.
+    *   **`--port` test**: The yargs `apply` function is working. The issue might be that `runMainWithArgs` re-imports `index.ts` which re-runs yargs parsing, potentially resetting `process.env.HTTP_PORT` if the test arguments don't include `--port`. Ensure the test arguments for `runMainWithArgs` in the `--port` test *include* the `--port 1234` args.
+    *   **`--json` test**: Filter out the `[INDEX_TEST_DEBUG]` and `[INDEX_TS_DEBUG]` logs from the `mockConsoleLog` assertion.
 3.  **`src/tests/server.test.ts` Timeouts (4 - `startProxyServer` suite):**
-    *   In the `startProxyServer` suite's `beforeEach`, ensure the `mockHttpServerListenFn` correctly simulates asynchronous listen by calling its callback (if any) with `process.nextTick`. Also, ensure the `http.createServer` mock consistently returns server instances that have properly mocked `on`, `once`, `listen`, `close`, `address` methods, especially for `findFreePort`'s internal usage.
+    *   In the `startProxyServer` suite's `beforeEach`, ensure the `mockHttpServerListenFn` correctly simulates asynchronous listen by calling its callback (if any) with `process.nextTick`. Ensure the `http.createServer` mock consistently returns server instances with properly mocked `on`, `once`, `listen`, `close`, `address` methods.
 4.  **`src/tests/integration/stdio-client-server.integration.test.ts` Failures (4):**
     *   **LLM Mocking (`generate_suggestion`, `get_repository_context`)**:
-        *   The `llm-provider` mock factory is confirmed to be called. The issue is likely that the `mockLLMProviderInstance` used by the SUT is not the one being configured with `mockResolvedValueOnce` in the test.
-        *   **Strategy**: In `src/tests/integration/stdio-client-server.integration.test.ts`, ensure the `mockLLMProviderInstance.generateText` is reset in `beforeEach` *after* `vi.clearAllMocks()`: `mockLLMProviderInstance.generateText.mockClear().mockResolvedValue("Default integration mock response");`. Then, in specific tests, use `mockLLMProviderInstance.generateText.mockResolvedValueOnce("Specific response for test A").mockResolvedValueOnce("Specific response for test B if needed");`.
+        *   **Strategy**: In `src/tests/integration/stdio-client-server.integration.test.ts`, in `beforeEach`, after `vi.clearAllMocks()`, explicitly re-assign the methods of the *existing* `mockLLMProviderInstance` object:
+            ```typescript
+            mockLLMProviderInstance.generateText = vi.fn().mockResolvedValue("Default mock from integration test beforeEach");
+            mockLLMProviderInstance.generateEmbedding = vi.fn().mockImplementation(async (text: string) => { /* ... */ });
+            mockLLMProviderInstance.checkConnection = vi.fn().mockResolvedValue(true);
+            // etc. for other methods if needed
+            ```
+            Then, in specific tests, use `mockLLMProviderInstance.generateText.mockResolvedValueOnce("Specific response for test A");`. This ensures the test is modifying the same object instance that the mock factory returns.
     *   **`get_session_history`**:
-        *   Add the planned logging to `src/lib/server.ts` (tool handler), `src/lib/state.ts` (`getOrCreateSession`, `addQuery`), and `src/lib/agent-service.ts` (`processAgentQuery`) to trace `sessionId` and `repoPath` flow.
-        *   In `src/lib/state.ts`, modify `addQuery`, `addSuggestion`, `addFeedback`, `updateContext`, `addAgentSteps` to throw an error if `sessions.get(sessionId)` fails (i.e., session not found), instead of trying to create one if `repoPath` is missing. This makes the "session not found" case explicit. `getOrCreateSession` should remain the primary way to obtain/create sessions.
+        *   The `addQuery` call in `agent-service.ts` seems to be working. The issue might be in the `get_session_history` tool handler in `src/lib/server.ts` when it formats the output, or if the session object is being mutated unexpectedly. Add logging within the `get_session_history` tool handler just before it formats the response, to dump the `session.queries` array.
     *   **`trigger_repository_update`**: Defer.

 *   `index.test.ts` failures (mocking `dist` code, yargs options).
