the public one, and the failure the report saw has to be run again to be placed.

# A served fact made at first start cannot be served, so the catalogue's authority cannot start
## Symptom, as observed
The catalogue's certificate authority module declares its root certificate, its root key and
that key's password as its own secrets, and writes each into a file the container is told to
initialise from. The mesh mints an own secret as random bytes. Random bytes are not a
certificate: as written, the authority cannot initialise, and no bed has ever raised it — the
whole-mesh bed that names it has not run since it was converted. Found while converting the
route-forwarding bed to the catalogue's proxy, which requires the authority beside it.
The authority can make its own root at first start — the certificate bed raises it that way and
it issues within a second. What it cannot do then is tell the mesh what that root is: a
consumer of `acme-ca` is given `${bound:acme-ca:root}` from the provider's `serves`, which is
written in the manifest before anything runs.
## Why it matters beyond this instance
- **Two kinds of secret the vocabulary does not distinguish.** A value the mesh may invent (a
password) and a value only the module can produce (a key pair, a certificate) are both
"own secrets", and the mesh invents both.
- **A served fact that exists only after first start** has no way into a binding. Anything a
module generates and its consumers must trust — a root, a public key, a fingerprint — is in
the same position.
- Every consumer of `acme-ca`, which today is the route proxy, is blocked with it.
## What would close it
Either a module may say a secret is *made by the module* — the mesh reserves the name, the
module writes the value once, the mesh takes custody of it and delivers it where it is bound —
or a served fact may be *contributed at run time* by the provider's runtime rather than written
in its manifest. The first is the smaller change and covers the root certificate; the second is
what a fingerprint or a public key wants. Decided, then the authority raised in the lab beside
the proxy, which is the route-forwarding bed's conversion.
