-**Tier 1** is the output cache — replays the prebuilt rendered report.
-**Tier 2** is the parse cache — skips the JSONL parse and classification step
-but rebuilds the output. **Cold** wipes cursor disk caches and forces a full
-SQLite scan through the parse pipeline.

-The "Cold" run scans all of this from disk. The 154 ms total includes parsing
-~150k JSONL lines plus a targeted SQLite query against the 1.5 GB Cursor DB.
