The compat badge was red on bookkeeping, not on compatibility: the check passed
16/16 and the run then failed trying to commit the refreshed matrix and open a
PR. That step should never have existed here — GitHub is a read-only mirror of
Gitea, so anything a bot pushes is clobbered by the next sync. It now publishes
the matrix to the run summary and the workflow only needs contents:read, so the
badge means what it says.
The README had grown into an implementation document. Endpoints, markup traps,
the login handshake and the drift-detection design move to docs/internals.md;
what is left is installation, entities, events, the dashboard, requirements and
troubleshooting.
