The uplink branch was split from the vault's with the vault's files reset to a main that did not yet hold #205; merging it afterwards took the older vault definition along (no claim, the refused event names), and the vault could not be built. Restored to #205's state.

// mesh-vault's provisioner — the adapter that makes vault a provider of the mesh `secret` interface. The
|
|
// reconcile loop, the contributions file, and reading the mesh's minted value are the sdk harness's;
|
|
// this writes only the per-service half (novox/hq ADR 0039/0040/0048) — and for a vault that half is
|
|
// taking custody, not creating anything.
|
|
//
|
|
// The `secret` interface (ADR 0085, design 24): a consumer requires a value for its own use — the
|
|
// password of a store it runs privately, an internal token — and reads it from the file the mesh
|
|
// writes on its machine. There is no server to create a login on. **The value is the pair
|
|
// credential itself**: the controller minted it, sealed it to both nodes, and delivered each its
|
|
// copy. What makes it *owned* is this: the vault records who holds it and its fingerprint, notices
|
|
// when `rotate secret` delivers a different one, and says so on the mesh. Rotation is not new
|
|
// machinery — it is the machinery that already moves a database password, pointed at a secret the
|
|
// vault provides (design 13).
