scale=0.2 made TP1 uniformly infeasible (no baseline); bound decode to 128 tokens and
use mild 2x compression so TP1 registers a real, fast baseline, with 6 probes to span
TP1's low and TP4's high feasibility boundaries. Both configs identical except use_harness.

First TP1 baseline probe under scale=0.2 ran ~6min (severe overload, 260
preemptions on the lighter half of the trace; TP1 is decode-bound and the
arrival-lag early-stop does not cut a decode-drain-bound probe). Cut
search.max_probes 5->3 to bound binary-search steps per trial. Caps stay
at elapsed=180/lag=30. Both configs still differ only in use_harness +
study_id.

At replay_time_scale=0.2 the 600s arrival window compresses to 120s, so
the inherited 900s wall-clock elapsed cap let overloaded TP1 probes burn
~15min each (the tractability hazard the brief flagged). Scale the caps
proportionately to the time axis: early_stop_max_elapsed_s 900->180,
early_stop_max_lag_s 120->30. Feasible probes (~120s arrival + drain)
finish well inside 180s; overloaded probes die in ~3min. Both configs
still differ only in use_harness + study_id. Adds the ablation doc
skeleton and a read-only trajectory-extraction helper.

Two configs identical except llm.use_harness and study_id, for the
controlled harness-ON vs naive-OFF tuning-trajectory ablation on dense
Qwen3.5-27B. Faster substrate (replay_time_scale=0.2, search.high=0.25,
max_probes=5) keeps the ablation tractable; Stop-A stays enabled.
