-Amber Signer Patch – Preserve Bunker Encryption Scheme
-======================================================
-
-1. Problem Statement  
-   Persisted bunker requests dropped their original encryption scheme (`encryptionType`). Whenever a pending request made a round trip through intents or storage and came back, the signer assumed NIP-44 for the response—even if the request had arrived encrypted with NIP-04. That broke compatibility with clients expecting NIP-04 and risked leaking plaintext.
-
-2. Proposed Solution  
-   Extend the custom serializer for `AmberBunkerRequest` to write out the `encryptionType` field, and add a focused unit test to guarantee that a serialized/deserialized request keeps its original scheme (e.g., NIP-04 stays NIP-04).
-
-3. Benefits  
-   - Restores protocol compliance and interoperability with NIP-46 clients that still rely on NIP-04.  
-   - Prevents accidental downgrade of encryption, preserving end-to-end confidentiality.  
-   - Introduces a regression test that protects the behaviour against future changes.
-
-4. Trade-offs  
-   - Slightly larger JSON payloads for persisted requests (one extra field).  
-   - Requires maintaining the new unit test alongside future refactors.
-
-5. Performance Implications  
-   Negligible: the change adds a single string field to serialized JSON and a tiny unit test; runtime cost is effectively zero.
-
-6. If Not Implemented  
-   - Responses to NIP-04 sessions would remain mis-encrypted, leading to failed signing flows and possible plaintext exposure.  
-   - Remote clients would see Amber as non-compliant with NIP-46, eroding trust and blocking adoption.
-
-7. Diff Summary  
-   - Updated `app/src/main/java/com/greenart7c3/nostrsigner/models/AmberBunkerRequest.kt` to serialize `encryptionType`.  
-   - Added `app/src/test/java/com/greenart7c3/nostrsigner/models/AmberBunkerRequestTest.kt` to assert round-trip integrity.  
-   - Noted the fix in `AMBER-review.MD`.
-
-8. Tests  
-   - `GRADLE_USER_HOME=$PWD/.gradle ./gradlew testFreeDebugUnitTest --tests "com.greenart7c3.nostrsigner.models.AmberBunkerRequestTest"` (passes).  
-   - Added unit test for serialization round-trip.
