 ## Boundary Rules
 
 - Blueprint remains library-only.
 - Identity abstractions are not owned by this repository.
 - Downstream repositories consume package contracts from this repo.
-- Secret provider abstractions are provider-agnostic; concrete provider adapters are bound at runtime.

-# Provider-Agnostic Secret Provider Rollout
-
-This package defines a provider-agnostic contract for secret lookup without binding to Vault, cloud providers, or environment files in core layers.
-
-## Contract Surface
-
-- `IBlueprintSecretProvider`
-- `BlueprintSecretReference`
-- `BlueprintSecretResolutionResult`
-
-## Runtime Defaults
-
-- `AddBlueprintKeyVaultModule(...)` now registers:
-  - `BlueprintKeyVaultRuntimeSettings` with:
-    - `VaultName`
-    - `SecretProviderName`
-  - `NoOpBlueprintSecretProvider` as default fallback.
-
-The default fallback returns unresolved lookups and never introduces provider-specific behavior.
-
-## Binding Strategy
-
-1. Keep domain and application layers dependent only on `IBlueprintSecretProvider`.
-2. Bind provider implementation at runtime through DI:
-   - Vault adapter
-   - Cloud secret manager adapter
-   - Environment/test adapter
-3. Keep one active provider per deployment profile.
-
-## Rollout Notes
-
-- Stage 33 keeps this contract-only baseline.
-- Concrete Vault/OIDC provider integration should be implemented in infrastructure/runtime layers only.
-- Existing identity logic ownership remains in Thalos repositories.
