miHAN Chat MVP
Production-like MVP implementation described by ../architectory and ../modules.
The current executable entry point is backend/docker-compose.yml; it is the
legacy VM1/stub contour, not evidence that the VM2 cutover is complete.
Target production has two independent root Compose projects/systemd units:
VM1 HAN Chat (backend/) and private VM2 Processing (message-safety,
bitrix-sync, ClamAV, Redis Safety, internal nginx and a local OTEL Collector).
Until the VM2 project is implemented, follow the existing backend guide only
for development/acceptance and the target runbook in
../modules/module-10-deployment-runbook.md for migration boundaries.
