This breaking pre-v1 minor migration adopts Promptkit's vanity module path,
changes the v0.16-era keyed resources to identified lists, adopts ConfigKit v1,
and removes prompt-version labels.
Promptkit does not install a provider catalog; applications choose configuration
Promptkit installs a default-on bundled OpenRouter catalog; applications choose configuration
inputs explicitly, and execution selects one prompt by its exact ID. This guide
explains the shape changes and decisions an application must make; it is not an
automatic migration tool. The [framework format reference](../formats.md) owns

The backend looks up
`OPENROUTER_API_KEY` when available; credentials are not required at engine
construction. For the complete inventory and diagnostic defaults see the
[format reference](../formats.md#bundled-openrouter-configuration). Use
`promptkit.WithBundledOpenRouter(false)` for application-only inventories.
Caller records replace matching bundled records in full; use `extends` with a
distinct ID to inherit. Replacing `auto` also changes its cost-tier children's
inherited target, while their plugins remain. External collections remain
supported.

### Choose A Profile Ownership Model
Supply backend and profile definitions through the configuration sources your
application selects. PromptKit does not install provider catalogs or built-in
profile inventories; conventional backend ID constants are names only. Define
the model, endpoint, credentials lookup, and settings that your application
application selects, alongside the default-on bundled OpenRouter inventory.
Conventional backend ID constants are names only. Define or replace the model,
endpoint, credentials lookup, and settings that your application
intends to support. A profile may inherit a sibling profile by its local key in
the same root or collection list; its backend reference uses the exact
configured identity. Caller-selected source layers determine the final values. The
