These were the canonical ablation evaluations until 2026-05-05, when the user re-ran all 6 ablation cells at the sweep-optimal RL temperature T=1.15 (rather than T=0.95). The T=1.15 results are now canonical at evaluation/eight_prompt/ablations/.

What's archived here

• ablations_t0.95/ — server-side-copy of the T=0.95 cell contents that previously occupied evaluation/eight_prompt/ablations/ in this bucket (mostly bucket-staged copies of the McClain/plasmidgpt-rl-* model evaluations at T=0.95)
• ablations_t0.95_source/ — the local strict-QC re-run of all 6 ablations at T=0.95 performed on g6-big (/opt/dlami/nvme/strict_qc_ablations/); per-cell outputs.csv + qc/ artifacts + metadata.json. Manifest at ablations_t0.95_source/manifest.json carries seed, sha256, and pass counts.

Numerical comparison

Ablation	T=0.95	T=1.15 (canonical)
full_reward	66.88%	78.35%
no_repeat_penalty	72.17%	75.15%
no_length_prior	71.38%	72.15%
no_cassette_bonus	19.80%	44.52%
length_only	34.73%	37.90%
cds_only	2.40%	1.73%

Cassette-bonus removal remains the largest single-component drop in both settings (47.1pp at T=0.95, 33.8pp at T=1.15). All ablations except cds_only improve at the higher temperature, consistent with the rejection-sampling sweep showing T=1.15 as the GRPO peak.
