"""Hermes Hub — Automated Release Gate & Verification Engine.

Strictly checks all criteria before allowing a release build:
1. Version consistency across manifests and code (0.1.1).
2. P0 Release Gate tests pass 100%.
3. Full offline test suite passes hermetically.
4. Auto-updater, cryptographic verification, and rollback pass.
5. Zero hardcoded developer paths (E:\\Agent projects, C:\\Users\\trush, etc.) in src/.
6. Zero secrets / keys / credentials in git repo.
7. Multi-Provider Router verification passes.
