WiSER training schedule used by the paper:
  P0 radiomap warmup
  P1 CIR restore with frozen scene encoder / radiomap head
  P2 radiomap refinement
  P3-P8 alternating CIR and radiomap refinement
  P9 final radiomap refinement

Public phase scripts:
  scripts/train_phase_radiomap.py
  scripts/train_phase_cir.py
  scripts/evaluate_dual.py

This wrapper is intentionally conservative: it does not launch a long training
job until users fill the data manifests and warm-start checkpoint paths in a
local run script.
