-api and worker are co-located on `anjie` while `nikola` and `frootmig` are out for drive replacement.
+Postgres roles `moments_rw` and `moments_ro` must exist on the primary, with `pg_ident.conf.d/<host>.conf` mapping the api host's FQDN → `moments_ro` and the worker host's FQDN → `moments_rw`. See `asset/sql/bootstrap-moments.sql`, `asset/postgres/ident.conf.tmpl`, and `script/db-perms.sh` (idempotently adds the cert_cn lines on the postgres primary + standby and reloads postgres).
 
-Postgres roles `moments_rw` and `moments_ro` must exist on the primary, with `pg_ident.conf` mapping `anjie.kosherinata.internal` to **both** roles (one cert_cn line per mapping). See `asset/sql/bootstrap-moments.sql` and `asset/postgres/ident.conf.tmpl`.
+Inter-host traffic over the WG mesh: web's nginx connects to the api host in plaintext. The mesh provides the encryption layer; per-hop TLS for an internal HTTP read-only API on already-public data is deferred. If that changes, swap the api binary to rustls + the host cert pair, and update the nginx upstream to `https://`.

If that changes, swap the api binary to rustls + the host cert pair, and update the nginx upstream to `https://`.
+Secrets are resolved at deploy time via `pass`. The mapping of env-var name → pass-store path lives under `worker.secrets` in `manifest.yml`; `deploy.sh` iterates the map, fetches each secret, and substitutes the matching `{{NAME}}` placeholder in `worker.env.tmpl`. To add a secret: add a `worker.secrets` entry, add `NAME={{NAME}}` to `worker.env.tmpl`, and ensure `pass show <path>` returns the value on the deploying machine.
