env-topology.sh exists precisely because vps2 runs two environments and one
host-wide marker cannot answer "which environment is this". The AppRole path is the
same question and had been given the same host-wide answer. It is now derived per
environment alongside host, checkout, branch, ports and DB role, and the renderer
resolves THERMOGRAPH_BAO_APPROLE, then TG_BAO_APPROLE, then the conventional path —
the same precedence render-secrets.sh:44 already uses for the backend selector.

Only beta differs. prod and dev keep the conventional path; dev is alone on vps1 so
there is no collision there.

Beta parity passes when the path is supplied by hand (24 keys = 8 + 16 shared);
this makes it automatic. Derivation confirmed by sourcing env-topology.sh for all
three environments.

render-secrets-openbao.sh resolved the AppRole file to a single host-wide default, /etc/thermograph/openbao-approle — which is prod's. On vps2 that made beta's render authenticate as tg-prod, and tg-host-prod.hcl denies thermograph/data/env/beta, so beta could never render from OpenBao. It surfaces as `cannot read thermograph/env/beta`: the policy working correctly against the wrong identity. env-topology.sh exists precisely because vps2 runs two environments and one host-wide marker cannot answer "which environment is this".
