+# NIP-46 Client Overview
+
+`js/nostr/nip46Client.js` implements the **Nostr Connect** (NIP-46) protocol, allowing the application to delegate event signing to a remote signer (e.g., a "Bunker" or mobile wallet) instead of managing private keys locally.
+
+## Architecture
+
+The communication happens over standard Nostr relays using **Kind 24133** (Nostr Connect) events. These events act as an RPC (Remote Procedure Call) transport layer.
+
+### Components
+
+1.  **`Nip46RpcClient`**: The central controller. It manages:
+    *   **Encryption**: Secures payloads using NIP-44 (XChaCha20) or NIP-04 (legacy AES).
+    *   **Subscription**: Listens for responses from the specific remote signer pubkey.
+    *   **Queueing**: Uses `Nip46RequestQueue` to serialize and throttle requests (preventing "rate-limited" errors).
+    *   **Session**: Persists connection details (remote pubkey, relays) to `localStorage`.
+
+2.  **`Nip46RequestQueue`**: A priority queue ensuring RPC calls are processed sequentially and respect relay rate limits.
+
+### Connection Flow
+
+1.  **Parsing**: The app receives a connection URI (e.g., `bunker://...` or `nostrconnect://...`).
+2.  **Handshake**: `Nip46RpcClient` initiates a `connect` RPC call.
+3.  **Verification**: If a `secret` was provided in the URI, the client verifies the signer's response matches it.
+4.  **Metadata**: The client fetches the user's public key via `get_public_key`.
+

+    Relay->>Client: Deliver Response
+    Client->>Client: Verify Secret & Permissions
+    Client-->>App: Connected
+```
+
+## Signing Flow
+
+When the app needs to publish a video or update a profile, it calls `signEvent`.

+    Relay->>Client: Deliver Response
+    Client->>Client: Decrypt & Parse
+    Client-->>App: Signed Event
+```
+
+## Security & Encryption
+
+*   **Ephemeral Keys**: The client generates a random local key pair for each session. The user's main private key is **never** transmitted.
+*   **Encryption Negotiation**: The client prefers **NIP-44 v2** but falls back to NIP-04 if the signer doesn't support it.
+*   **Auth Challenges**: If the signer requires out-of-band authentication (e.g., scanning a QR code), it returns an `auth_url` error, which the client bubbles up to the UI.
+
+## Key Functions
+
+*   `parseNip46ConnectionString(uri)`: specific parser for `bunker://` and `nostrconnect://` URIs, extracting secrets, relays, and remote pubkeys.
+*   `createNip46Cipher(...)`: Factory that creates an encryption interface (encrypt/decrypt) based on available libraries and negotiated algorithms.
+*   `decryptNip46PayloadWithKeys(...)`: Helper to brute-force decrypt an incoming message using all available algorithms (handling legacy vs modern formats).
+
+## Error Handling
+
+*   **Timeouts**: RPC calls have a default timeout (15s).
+*   **Rate Limiting**: If relays reply with `rate-limited`, the client performs exponential backoff.
+*   **Session Recovery**: On page load, `readStoredNip46Session` rehydrates the session from `localStorage` to resume without re-connecting.
+
+## When to change
+
+*   **Protocol Updates**: If NIP-46 or NIP-44 standards are updated (e.g. new encryption vectors, new RPC methods).
+*   **Security Audit**: If a security review identifies weaknesses in the ephemeral key handling or encryption flow.
+*   **Relay Logic**: If the strategy for relay selection or rate-limiting needs to be optimized for better connectivity.
