Intent
The v2 arm of the schedule-optimization campaign gathers every experiment
scored against the re-frozen objective: the probability, over random
seeds, that unseen_mismatch accuracy reaches m_star = 95.5 within
k = 350 steps, guarded by the same two-waypoint dwell
(experiments/schedopt/config_v2.json). Its members are the Step-D
search round that re-searched the three-parameter schedule family at the
corrected point, the Phase-4 rounds that added a tooth-amplitude parameter
riding the ramp, and the Step-F confirmation on fresh held-out seeds. The
operating point was re-frozen only after the Phase-3 confirmation had been
seen, and it was chosen from search and calibration data alone so that the
held-out comparison stayed honest. Nothing here confirms a v1 result: the
re-freeze is always reported as a re-freeze, the two operating points are
never merged, and no number recorded under v2 is comparable to a number under
v1.

Step F of the schedopt re-freeze continuation: the only reportable numbers at the re-frozen operating point v2 (m_star=95.5, k=350, dwell 2), on 150 fresh held-out seeds never used by any selection. Five arms: the Phase-4 modulation winner, the best smooth schedule (which is also the original campaign's winner), the ascending smooth carry-forward, the fixed-α baseline, and the off-family burst reference at its original 400-iteration realization. The objective was re-frozen after the Phase-3 confirmation was seen; nothing here confirms the v1 result, and v1 and v2 numbers are never merged. Adjudication follows the pre-registration committed before the Phase-4 search (
experiments/schedopt/phase4_prereg.md). -

Step E of the schedopt re-freeze continuation (Phase 4), round 9: eight candidate schedules from the four-parameter modulation family, the three-parameter ramp multiplied by (1 + A·w) with amplitude A in [0, 1] and w pinned to
burst_16's realized tooth wave (period 400/3 steps, duty 0.5, peak-first), proposed by Thompson sampling from a Gaussian process warm-started from every three-parameter evaluation re-expressed at A = 0 and scored at the re-frozen operating point v2 (m_star=95.5, k=350, dwell 2) over the shared search seed pool. The pre-registration (experiments/schedopt/phase4_prereg.md) precedes every run of this phase; v1 and v2 numbers are never merged. -

Step D of the schedopt re-freeze continuation (Phase 2b), round 5: eight candidate schedules proposed by Thompson sampling from a Gaussian process re-fitted to every prior evaluation re-scored at the re-frozen operating point v2 (m_star=95.5, k=350, dwell 2) — the v1 objective saturated, and this round searches the speed-measuring point instead. Same search seed pool (common random numbers); adaptivity lives between rounds only; v1 and v2 numbers are never merged.
