Grafana on ace answers 401 to the vault's admin password, every 30 s since at least 2026-10-05. I think the cause is
the adoption: Grafana keeps the admin password it was first given in its database and applies
GF_SECURITY_ADMIN_PASSWORD__FILE only when it creates it; ace's Grafana came with its database before the mesh minted
own/ace/grafana/admin (2026-09-30, generation 1, unchanged since), so the minted value never took (keycloak's
admin, hq issue 179, is the same kind).
Quick fix: none in code; the password in Grafana's database must become the vault's (grafana cli admin
reset-admin-password in the container), an act on ace no tool offers yet. Thorough fix: a step that converges the
admin password at every start, which needs a container entrypoint the node-engine's declaration does not carry.
This commit does what the catalogue can now: the refusal is said once with its cause and what ends it, asked again
hourly, and its end is said.
