+# Secrets rule
+
+Все креды (SSH, БД, panel, BA) лежат в `pass` (password-store). **Перед поиском доступов — `pass ls` / `pass show <path>`, а не grep по вики или `~/.ssh/config`.**
+Серверы СТО Стайер: `stostayer/client` (`new.stostayer.ru:20435` — машина клиента, файлы 1С в `/var/from_1c/`), `stostayer/rusonyx`, `stostayer/client-wireguard`.
+
+# VDS ops rule
+
+Все docker-compose stacks на VDS управляются через Portainer (`https://portainer.vds.kzntsv.site`).
+`ssh + docker compose up -d` на VDS — anti-pattern. См. [`portainer-stack-management-vds`](.wiki/concepts/portainer-stack-management-vds.md) для migration script + gotchas.
+Исключения: `traefik` + `portainer` (management plane, ad-hoc compose).
