App layer (R1): bind frps NewProxy to token-owned subdomain (anti-hijack), default-deny unknown webhook ops, HMAC-verify stripe-stub billing webhook, enforce bandwidth quota kill-switch (Ping op), least-privilege table grants (migrations 0002/0003), GOTRUE_PASSWORD_MIN_LENGTH=12. Infra/net (R2): unpublish internal host ports (kong/pooler/analytics/frps-dash), read-only docker-socket-proxy for vector (no host breakout), on-demand-TLS allow-list authorizer, edge-block machine-only webhooks, no-new-privileges on custom containers. Secrets (R3): rotate Postgres password (all roles) + frps dashboard; replace predictable supavisor defaults; secrets externalized to gitignored .env. Med/Low (R4): security response headers (HSTS/XCTO/XFO/Referrer/Permissions/COOP), restrict frp proxy_type to http (no open relay), disable destructive redis commands, tighten frps.toml perms. No secrets committed; rotated values live only in gitignored .env files.
/docker — linumiq.net remote access stack
Networks
Shared external docker network: edge (created with docker network create edge).
Shared env
/docker/.env — DOMAIN, LE_EMAIL.
Per-service secrets
/docker/<svc>/.env, all chmod 600, owned root:root. See /docker/SECRETS.md
for the inventory.

Reverse of the above. docker compose down per directory.
Edge functions
Mounted from /docker/supabase/volumes/functions/. The main function is a
router that reads the first URL path segment as the function name.
- Via Kong:
POST http://127.0.0.1:8000/functions/v1/<name> - Direct (intra-
edgenetwork, e.g. frps auth plugin):POST http://supabase-edge-functions:9000/<name>
After editing a function, cd /docker/supabase && docker compose restart functions
(or up -d functions if env changed).
