Captures every candidate block (5,10,...,45, plus DEFAULT_BLOCK=25)
read-only alongside the one that actually steers, so block_sweep()
can answer "which block really separates liked from disliked" from
data already being collected -- reusing trajectory_probe's own
permutation test (proven correct on this project's real data) instead
of trusting REINS' 50%-depth heuristic (their own paper picks the
best layer per model by sweep, not by applying one universal
percentage) or porting a diagnostic built for a different question
(LTXAV's identity-block search measured cross-scene consistency, not
liked-vs-disliked separation).
Grouped by prompt_hash (trajectory_probe's own, reused) so cross-
prompt content differences can't masquerade as a rating signal -- the
same confound that inverted the first cross-prompt read of this
project's output value function.
Settings > Learning > Refinement & Taste gets a per-key REINS panel
(status, block-sweep table, export/clear) mirroring the trajectory
probe UI, plus matching /api/h3_repr_steering routes -- so data can
be pulled off a rental and handed over directly instead of relayed
through pasted console logs.
