passages: four-strate passage floors supported (L67, evaluator v212); 1-2 wall beat still red

- Shared composer: a passage's restored support is applied after a physically overlapping
  later bore, instead of being carved away by it (0-1: 59 -> 0 unsupported).
- Capsule clearance for support restoration is tested against nearby route segments only
  (1-2: 3 -> 0, 2-3: 2 -> 0 unsupported).
- L66 index switches replaced by a physical criterion (both mouths inside their strata bands,
  neither a SurfaceWorld landing).
- Audit: floor zero-crossing refined by bisection (the 0.2498 m "step" was the gauge);
  wall ripple keeps the authored radius, cubic detrend per 32 m window. Controls detected:
  L35 ribs, beads, synthetic 0.25 m step, L36 washboard, L23 terrace.
- Result: 0-1 and 2-3 pass all audits; 1-2 fails wall ripple 7.27 cm (limit 3.5) from an
  authored-radius beat at 7.06 m. Fast tier was green before the final gauge change and was
  not re-run after it.
