CALANAIS ORDERED-AXIS / ADVERSARIAL REPRODUCIBILITY LAYER v4

Carries forward all v3 adversarial files and adds:
- ORDERED_VECTOR_LOCK_v4.md
- ORDERED_VECTOR_LOCK_v4_RESULTS.json
- vector_endpoint_reconstruction_v4.py
- vector_endpoint_reconstruction_v4.csv

Interpretive rule: the spatial S* reconstruction is a re-expression of the same frozen directional partition statistic. It is NOT an independent evidential channel and is NOT assigned a second p-value. Its purpose is to expose the physical consequence of role exchange: the ordered L->L/T->T assignment predicts the held-out surviving S endpoint within 0.964 m, whereas every axis-swapped assignment misses by at least 47.590 m.

The v3 null calibrations remain unchanged and are not multiplied. Retained negative results remain unchanged, including ES=EW FAIL and P != archaeological ring centre.
