qd-archive-update

Maintains the Quality-Diversity archive at oniro/archive/.

Procedure

1. Compute the variant's descriptor: (slot_purity, jepa_loss_bucket, action_acc).
2. Locate the MAP-Elites cell from the descriptor.
3. Call QDArchive.insert(variant):
   • If gate ACCEPT: place as canonical, supersede the prior elite iff fitness strictly higher.
   • If gate REJECT but novelty(descriptor) > 0.7 and the cell is empty: place as provisional (cannot supersede a parent, may seed mutations).
   • Otherwise: discard.
4. Append a line to oniro/archive/lineage.jsonl recording the decision.

Output

{
  "placed": true,
  "cell": [2, 1, 3],
  "tier": "canonical",
  "reason": "fitness 0.71 > prior elite 0.68"
}
