"""Escribe SHA-256 de los artefactos fuente/reproducibles incluidos en el paquete.

Exclusiones (no forman parte del punto fijo del manifiesto):
  - MANIFEST.sha256 — evita hash auto-referente
  - AUDITORIA_AUTO.md — regenerable con timestamp
  - ontology/io_ontology.ttl — regenerable; orden de serialización rdflib no es
    estable byte-a-byte entre corridas (CI lo regenera antes de SHACL)
  - __pycache__, .pytest_cache, .venv

Los CSV canónicos (triad_nodes, vector_steps, relation_candidates) SÍ entran:
son el punto fijo de generate_ontology.py.
