# Comprehensive internal-process walk.
#
# Phases:
#   A) Pause / resume — multiple intervals merge into duration_actual
#   B) Skip an opt-in step
#   C) Skipped steps don't block job mark-done
#   D) Wet plating step finish auto-spawns bake.window with right window_hours
#   E) Bake-window state evolves (awaiting_bake → bake_in_progress → baked)
#   F) Failure: try to start a step already done
