```
**Note:** The `discord_bot_token` secret is the only value read directly by this
Discord channel WASM component. The `discord_app_id` and `discord_public_key`
secrets are used by the IronClaw host (for example, to verify Discord
interaction signatures and manage slash command registration) and are not
accessed from the WASM module itself.
**Note:** The `discord_bot_token` secret is used for Discord REST API calls.

## Advanced Usage
### Mention Polling
The Discord channel can also poll configured channels for `@bot` mentions.
Example channel config:
```json
{
"require_signature_verification": true,
"webhook_secret": "YOUR_DISCORD_PUBLIC_KEY_HEX",
"polling_enabled": true,
"poll_interval_ms": 30000,
"mention_channel_ids": ["123456789012345678"],
"owner_id": null,
"dm_policy": "pairing",
"allow_from": []
}
```
### Access Control
- `owner_id`: when set, only that Discord user can interact with the bot.
- `dm_policy`: `open` allows all DMs; `pairing` requires approval.
- `allow_from`: allowlist entries for DM pairing checks (`*`, user id, or username).

- This validation happens on the host before reaching the WASM.
- Check that `webhook_secret` is set to your Discord app public key hex in the
