check the bot performance and if it is still running, if it has stopped check why fix the bug and restart it

## Assistant

I'll start by looking at the project structure to find the bot process and how it's run.

## Assistant

Found it — the bot crashed today at 09:31:05 with a `TypeError` in `winner_score.py`, and the tmux session's pane is just sitting at a bash prompt (not running monitor.py). Let me look at the crash site.

## Assistant

Now let me apply the fix — resolve `as_of` once at the top of `evaluate_entry_pipeline`, matching the pattern used everywhere else in this codebase (`stream_features.py`, `entry_score.py`), so a real timestamp gets stored in `score_history` instead of `None`.

## Assistant

This looks correct. Also, I should defensively harden `winner_score.py` in case any stale `None` timestamps are already sitting in a live `state` dict in memory (irrelevant now since the process crashed and will restart cleanly, but worth checking if there's a persisted state file).

## Assistant

No persisted `score_history` to worry about — it's in-memory only, so a clean restart clears it. Let me check for a stale PID lock and find how the bot is normally started.

## Assistant

Good — it uses `flock`, not a stale-PID check, so since the crashed process already exited, the OS released the lock automatically. No manual cleanup needed. Now let's verify the fix with a quick syntax check and the existing test suite before restarting.

## Assistant

These two failures are in `entry_engine`/monitor shortlist logic — unrelated to `prediction_pipeline.py`/`winner_score.py` (the module I touched isn't even imported by them), and they involve `entry_engine.evaluate_entry` momentum/volume thresholds, not the crash I fixed. They're pre-existing, not a regression from my change. Now let's restart the bot in the tmux session.

## Assistant

Confirmed paper mode (Alpaca paper account, no real money). Restarting now, matching the exact cron invocation.

## Assistant

monitor.py is running again (PID 219163). Let me tail the log to confirm it's progressing past the point where it crashed before.

## Assistant

It restarted cleanly and is running the premarket scan now. Let me wait a bit and confirm it gets past the entry pipeline stage (where it crashed before) without error.
