Per Andrey: static per-tile dx offsets found in -POSE-RT-HYPER (e.g. tile
x=15,y=41: dx mean +0.92 constant over all 497 scenes, far tile disp 0.02;
tile x=71,y=51: dx +0.86 dy +1.91, near tile disp 13.2 - neighbors with
similar disparity are near zero) -> suspect broken per-tile task data.

New checkbox "Pose test stored poses (no LMA)" (curt.pose_stored): every
scene is measured/rendered at its STORED (oracle-vintage) pose, the LMA is
skipped entirely. -POSE-RT-HYPER/-CORR2D/-COMPOSITE come from that single
measurement; CSV rms column = weighted RMS of the measured offsets.
The -POSE-RT-COMPOSITE "real" component must then match the oracle
CUAS-MERGED-CUAS-DBG per-scene renders tile-for-tile (and "virtual" its
[average] slice) - any mismatch localizes the broken tiles in the
task/render/correlation chain, independent of the solver.

Observability only - the fitting paths are unchanged.
Verified: mvn -DskipTests clean package OK.
