// mssql's provisioner — the adapter that makes mssql a provider of the mesh `mssql-database`
|
|
// interface. The reconcile loop, the contributions file, and reading the mesh's minted password
|
|
// are the sdk harness's; this writes only the per-service half: how mssql creates and removes a
|
|
// consumer's database + login/user with the mesh-minted credential (novox/hq ADR 0039/0040/0048).
|
|
//
|
|
// The `mssql-database` interface: a consumer connects to a database it alone owns, as `as` with
|
|
// the password the mesh minted.
|
|
//
|
|
// **The login name and password are the mesh's, not the provisioner's (ADR 0048).** The mesh
|
|
// derives the login and hands it to both ends, and mints the password. mssql creates a login, a
|
|
// same-named database, and a db_owner user under exactly that login — a name the consumer cannot
|
|
// learn is a database it cannot reach.
|
|
//
|
|
// The DDL runs through MssqlClient, which is the module's one pending boundary (see client.ts).
