What and why

Closes #485. Same family as #236, in a query it didn't cover.

• Activity (sentient/activity/timeline.py): Timeline._call_arguments read a chat tool call's arguments from the latest assistant message with tool_calls at or before the tool result's created_at. Windows' clock advances every 15.6 ms (Python 3.12's time.time() uses GetSystemTimeAsFileTime; 200,000 calls here gave 109 distinct timestamps), so a tool result and the next call often share a timestamp, and the query could pick the next call's message and drop this call's "query: ..." line. It now finds the message that holds the call's id (instr(tool_calls, '"<id>"') > 0), still the latest one at or before the result.
• Test (tests/test_claude_code.py): test_stop_everything_drops_calls_still_waiting killed the fake Claude Code as soon as the process existed, but the fake logs its run only after claude.cmd, cmd.exe and Python have started and it has read the prompt, so on a slow start fake_claude.runs() was empty. It now waits until the fake has logged its run. Test-only.
• changes/485.fixed.md.

How I tested it

• New tests/test_timeline.py::test_a_calls_details_survive_a_shared_timestamp: two calls whose messages all share one created_at; each call's arguments are found. It fails without the fix.
• On a Windows 11 laptop where both tests failed about 5 runs in 6 with main unchanged: test_chat_tool_calls_and_approvals_say_what_and_why, test_stop_everything_drops_calls_still_waiting and the new test passed 8 runs out of 8, then 5 out of 5 on this branch.
• pytest -q tests/test_timeline.py tests/test_claude_code.py: 45 passed. Full suite (Windows), with these fixes and my feat(api): let other apps chat with Sentient through an OpenAI-compatible API #479 branch together: 2735 passed, 2 skipped, nothing deselected.
• ruff check sentient tests packaging: clean.

Real test

• No engine run: the fix is a query that reads the database, and the regression test exercises it on a real SQLite store with the timestamps forced equal. The flaky failure itself was reproduced and is gone on the Windows machine above.

Checklist

• Tests added or updated, and pytest / npm run typecheck pass locally for what I touched
• ruff check sentient tests is clean
• docs/API.md updated if the desktop ↔ engine contract changed (not changed)
• A changelog entry in changes/ (changes/485.fixed.md)
• No keys, tokens or personal data in the code, tests or screenshots

Summary by CodeRabbit

• Bug Fixes

  • Fixed Activity on Windows so chat-tool inputs display correctly, including queries saved at the same time as other tool calls.
  • Prevented tool calls with matching timestamps or special characters in their identifiers from displaying another call’s arguments.

• Tests

  • Added regression coverage for distinguishing simultaneous tool calls and handling special-character identifiers.
  • Improved concurrency test synchronization for more reliable results.

📝 Walkthrough

The timeline now selects assistant messages that contain the requested tool-call ID. Regression tests cover escaped IDs and shared timestamps. The stop-everything test waits for the fake Claude Code run to be recorded.

Changes: Activity call details

Layer / File(s)	Summary
Match arguments by call ID sentient/activity/timeline.py, tests/test_timeline.py, changes/485.fixed.md	The timeline lookup matches the requested tool-call ID, including JSON-escaped IDs. Tests cover calls with identical timestamps. The changelog records the Windows correction.
Wait for the fake CLI run tests/test_claude_code.py	The stop-everything test waits for both the live state and a recorded fake CLI run.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix · Severity of issue fixed: Medium

Merge Risk: 🟡 Moderate · up to 7ddf6

The Activity fix can still omit tool inputs in a reachable call-order case, and the Windows synchronization test can race on slow startup; both should be corrected before merging.

Full details: Linked Issues check

Explanation

Issue #485 is directly linked and has coding requirements. sentient/activity/timeline.py now filters assistant messages by json.dumps(call_id) while retaining the created_at constraint, then validates the call ID before reading arguments. tests/test_timeline.py covers shared timestamps and JSON-escaped IDs. tests/test_claude_code.py waits for the fake run log before starting the queued call. These changes implement the issue requirements. The reported focused test run passed 45 tests.

Full details: Out of Scope Changes check

Explanation

The changed production code directly fixes issue #485. The timeline tests cover the required regression and escaped IDs. The Claude Code test change fixes the Windows startup race named in issue #485. changes/485.fixed.md documents the fix. No unrelated change is shown.

Beside the timestamp’s crowded wall.
Escaped IDs now lead the way,
While Claude waits for logs to stay.
Windows queries bloom in view,
And tests confirm the details true.}

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Do not continue after the polling timeout.

When 300 polls expire, the loop exits normally even if fake_claude.runs() is still empty. second then starts before the first fake run is recorded, which can race with the later process-count and run-count assertions on a slow startup.

Suggested fix

     for _ in range(300):  # running and logged, not just spawned: slow to start on Windows (claude.cmd, then Python)
         if claude_code._live and fake_claude.runs():
             break
         await asyncio.sleep(0.05)
+    else:
+        raise AssertionError("The first fake Claude Code run was not recorded")
     second = asyncio.create_task(one())

Thanks @Tanmay-Ts, nice catch and a careful fix. I reproduced it on main with a real engine: a call whose result shares a timestamp with the next call lost its "query: ..." line in Activity. With your branch, both calls keep their details, and the restore path is fixed too. Your reasoning on the CodeRabbit thread holds. Approving and merging!
