{"_meta": {"battery": "5f", "sub_battery": "finetuning", "version": "v1", "task_count": 6, "notes": "#000025 §10.11: shard-chain Finetuning — reads the two most-recent SelfModel snapshots from a PERSISTENT chain shard (default ~/.arborist/shards/selfmodel-chain.db, override via ARBORIST_SELFMODEL_CHAIN_DB) and measures improvement on target_capability between them. The chain is grown one snapshot per run by `make bench-5f-selfmodel-snapshot`; run THAT (>=2x) before this pack. Tasks fail honestly if the shard is absent / too short — this is an operator pack, not part of `make bench-5f` or the default test suite. expected_improvement_min=0.0 = a no-regression assertion (the embedded packs are at ceiling, so the chained delta is 0.0)."}}
