     - `Call to untyped function (unknown) in typed context`.
   - Fix implemented locally: renamed the all-resumed branch result variable and
     replaced the untyped cleanup lambda with a typed `_noop_cleanup()`.
+- Commit completed:
+  - `022aedb0` — `[bugfix] clean up interleave eval mypy`
+  - Pushed to `origin/interleavethinker-fastvideo`.
+- Final pushed-branch Modal validation:
+  - App URL:

+- Add trace-level evaluation scripts for saved prompt-set outputs:
+  `scripts/interleave_thinker/evaluate_traces.py` and/or a small HTML/contact
+  sheet report. The prompt-set runner now produces the trace and summary
+  artifacts those tools can consume.
