- [X-095] DT512 · DT512 · question: Does halving the deep tier's thinking budget (DEEP_THINKING_BUDGET 1024 -> 512, arm H) keep the thinking gain vs T (DEEPTHINK, 1024) while cutting time (with D = DEEPVPARA no-thinking for the ladder)? · result: 512 vs 1024 on V-para: raw +0.011 (−0.010…+0.031), floor-adjusted +0.014 (−0.012…+0.039), ×0.55 time; on v0.2 −0.005 (−0.020…+0.009), ×0.62 time. · set V-para (V-para); v0.1 (smoke, 2 items), judge Claude Opus, Claude Haiku (L1), n 51 judged ids (58 generated) x 2 seeds; slice 20, seeds 42, 43 (third seed 44 noted later via SEEDVAR), CI −0.010…+0.031 · verdict: parity (closed (CHEAPER-PARITY; 512 kept as a local engine recommendation, not in a claim cut))

- [F-009] Recommended deep configuration (35B mixture-of-experts + 512-token thinking budget) on the bounty-style set. raw 0.553 (0.524–0.581; with seed noise 0.513–0.592); floor-adjusted 0.436 (0.401–0.472; with seed noise 0.387–0.486); win 0/51; desktop p50 ≈ 79 s (judge.v1 ratio) · set V-para (dev-style, development data) · judge Claude Opus (judge.v1, both orders) · n 51 · seeds 2 · CI 95 % item bootstrap; common-mode CI adds seed noise · date 2026-10-09 · caveat: Chosen as the best of ≥ 8 deep configurations on this same set: expect a winner's-curse discount of about 0.01–0.02. QUEUE prints raw 0.552; the two-seed aggregate is 0.553. Desktop only.
- [F-010] A 512-token thinking budget matches 1024 in quality at about half the time. 512 vs 1024 on V-para: raw +0.011 (−0.010…+0.031), floor-adjusted +0.014 (−0.012…+0.039), ×0.55 time; on v0.2 −0.005 (−0.020…+0.009), ×0.62 time (judge.v1 ratio) · set V-para; v0.2 (dev-style / dev, development data) · judge Claude Opus (judge.v1, both orders) · n 51 / 110 · seeds 2 (V-para) / 1 (v0.2) · CI paired 95 % bootstrap · date 2026-10-09 · caveat: Verdict label: CHEAPER-PARITY (an equivalence, not a gain).
- [F-523] R20 Budget 512 vs 1024: 2 seeds. +0.011 (−0.010…+0.031), ×0.55 time · set UNKNOWN (status UNKNOWN) · judge UNKNOWN · n UNKNOWN · seeds UNKNOWN · CI not computed · caveat: why closed: CHEAPER-PARITY → 512 adopted
