Vendor OpenClaw source as Adolf fork baseline

Adolf is a fork/vendored clone of github.com/openclaw/openclaw (v2026.6.11),
free to diverge. Tree copied sans upstream .git; upstream remote added for
future syncs. Node pinned to 24 (.nvmrc); engines already require >=22.19.

+# @openclaw/nostr
+
+Nostr DM channel plugin for OpenClaw using NIP-04 encrypted direct messages.
+
+## Overview
+
+This extension adds Nostr as a messaging channel to OpenClaw. It enables your bot to:
+
+- Receive encrypted DMs from Nostr users
+- Send encrypted responses back
+- Work with any NIP-04 compatible Nostr client (Damus, Amethyst, etc.)
+
+## Installation
+
+```bash
+openclaw plugins install @openclaw/nostr
+```
+
+## Quick Setup
+
+1. Generate a Nostr keypair (if you don't have one):
+
+   ```bash
+   # Using nak CLI
+   nak key generate
+
+   # Or use any Nostr key generator
+   ```
+
+2. Add to your config:
+
+   ```json
+   {
+     "channels": {
+       "nostr": {
+         "privateKey": "${NOSTR_PRIVATE_KEY}",
+         "relays": ["wss://relay.damus.io", "wss://nos.lol"]
+       }
+     }
+   }
+   ```
+
+3. Set the environment variable:
+
+   ```bash
+   export NOSTR_PRIVATE_KEY="nsec1..."  # or hex format
+   ```
+
+4. Restart the gateway
+
+## Configuration
+
+| Key          | Type     | Default                                     | Description                                                |
+| ------------ | -------- | ------------------------------------------- | ---------------------------------------------------------- |
+| `privateKey` | string   | required                                    | Bot's private key (nsec or hex format)                     |
+| `relays`     | string[] | `["wss://relay.damus.io", "wss://nos.lol"]` | WebSocket relay URLs                                       |
+| `dmPolicy`   | string   | `"pairing"`                                 | Access control: `pairing`, `allowlist`, `open`, `disabled` |
+| `allowFrom`  | string[] | `[]`                                        | Allowed sender pubkeys (npub or hex)                       |
+| `enabled`    | boolean  | `true`                                      | Enable/disable the channel                                 |
+| `name`       | string   | -                                           | Display name for the account                               |
+
+## Access Control
+
+### DM Policies
+
+- **pairing** (default): Unknown senders receive a pairing code to request access
+- **allowlist**: Only pubkeys in `allowFrom` can message the bot
+- **open**: Anyone can message the bot (use with caution)
+- **disabled**: DMs are disabled
+
+Inbound event signatures are verified before policy enforcement and NIP-04 decryption.
+Unknown senders in `pairing` mode can receive a pairing reply, but their original DM body is not
+processed unless approved.
+
+### Example: Allowlist Mode
+
+```json
+{
+  "channels": {
+    "nostr": {
+      "privateKey": "${NOSTR_PRIVATE_KEY}",
+      "dmPolicy": "allowlist",
+      "allowFrom": ["npub1abc...", "0123456789abcdef..."]
+    }
+  }
+}
+```
+
+## Testing
+
+### Local Relay (Recommended)
+
+```bash
+# Using strfry
+docker run -p 7777:7777 ghcr.io/hoytech/strfry
+
+# Configure openclaw to use local relay
+"relays": ["ws://localhost:7777"]
+```
+
+### Manual Test
+
+1. Start the gateway with Nostr configured
+2. Open Damus, Amethyst, or another Nostr client
+3. Send a DM to your bot's npub
+4. Verify the bot responds
+
+## Protocol Support
+
+| NIP    | Status    | Notes                  |
+| ------ | --------- | ---------------------- |
+| NIP-01 | Supported | Basic event structure  |
+| NIP-04 | Supported | Encrypted DMs (kind:4) |
+| NIP-17 | Planned   | Gift-wrapped DMs (v2)  |
+
+## Security Notes
+
+- Private keys are never logged
+- Event signatures are verified before processing
+- Sender policy is checked before expensive crypto work
+- Inbound DMs are rate-limited and oversized payloads are dropped before decrypt
+- Use environment variables for keys, never commit to config files
+- Consider using `allowlist` mode in production
+
+## Troubleshooting
+
+### Bot not receiving messages
+
+1. Verify private key is correctly configured
+2. Check relay connectivity
+3. Ensure `enabled` is not set to `false`
+4. Check the bot's public key matches what you're sending to
+
+### Messages not being delivered
+
+1. Check relay URLs are correct (must use `wss://`)
+2. Verify relays are online and accepting connections
+3. Check for rate limiting (reduce message frequency)
