+1. Download the zip from Notion (refuse-reshuffle pack after Boof refresh).
 2. Prefer `gold_observed.jsonl` for T0/T1 gold; full splits in `train.jsonl` / `val.jsonl` / `test.jsonl`.
 3. Keep `keep_weak.jsonl` out of gold unless you set an explicit weak-lane flag.

 5. Encoder gate: `specs/004-encoder-gate/`. `name_gate` stays **false** until your eval is green.
 6. HF Hub skipped (Danny). Boof `ALLOW_TRAIN` is false — run train on Spark.
