+# PRODUCTION_DEPLOYMENT_REPORT
+
+Дата: 2026-07-15  
+Ветка: `feature/maximum-demo-realism`  
+Базовый commit этапа 1: `985f7c3`  
+Production bundle после этапа 2: `index-ncgt6PBL.js`
+
+## Способ деплоя
+
+Docker-контейнер `owl-web-1` (image `owl-web:<release>`), порт `127.0.0.1:3100→80`.  
+Docker API: `DOCKER_HOST=tcp://127.0.0.1:2375` (из coder-контейнера).  
+Compose-файл: `docker-compose.server.yml` (исторически `-p owl`).  
+Скрипт: `scripts/deploy-production.sh`.
+
+Публичный доступ в этой среде:
+
+- Loopback: `http://127.0.0.1:3100/`
+- Quick tunnel cloudflared: `https://invitations-based-characters-accent.trycloudflare.com/`
+- `https://arhipovdan.ru/` из контейнера даёт TLS SNI / openresty 404 — DNS/прокси домена вне текущего coder-окружения; проверяйте снаружи.
