- NEW cuas/rt/CuasRT.java: the ENTIRE CUAS RT mode moved out of
  OpticalFlow.buildSeries (curt_en branch) into one readable top method:
  1. INITIALIZATION (ingest, photometric calibration, center appropriation)
  2. DIAGNOSTICS (rend/pose/cond tests - exclusive, never grow the top)
  3. PRODUCTION (detection; the MVP per-scene jp4 loop will replace the
     bulk oracle ingest without changing this structure).
- Borrow boundary (Andrey ruling): all transforms of borrowed QuadCLT data
  happen at CuasRT initialization ONLY. appropriateCenter() zeroes the
  center CLT IN MEMORY (setCenterClt; -CLT-UPDATED is saved upstream, so
  the zeroed copy never persists) - the pose test drops its per-run GPU
  appropriation and uploads an already-zeroed reference. The pure math is
  CuasConditioning.zeroDcClt(fclt, pattern, level) - knows no QuadCLT.
- FIX (POSE-09 silent no-op): the DC-pattern uniform image must be set on
  gpuQuad.getQuadCLT() - what both backends actually read (GpuQuadJna
  setBayerImages(center=true), JCuda base, CorrectionFPN recipe) - not on
  center_CLT; plus an all-zero-pattern guard (warn loudly, never fake-offset).
- FIX (POSE-09 1470-count per-sensor sky spread vs 17 calibrated):
  rtPhotometricCalibration applies the fit to the ALREADY-SPAWNED per-scene
  instances too (created by ingest before the calib step). The recalibrated
  photometric persists only via ref INTERFRAME + a config save after a
  calib-ON run - all current configs still carry the stale values.
