"""Vaultfire NanoLoop v1.1

Extends the v1.0 cell-scale deployment module with regenerative
operations, trauma stabilization, and adaptive tissue encoding.
Ethical safeguards are inherited from ``nanoloop_v1`` and advanced
healing cycles are linked to Purpose Engine v2 using belief signals.
Nothing here is medical advice. It provides configuration and
logging helpers only.
