 - UI: add optional `ui.seamColor` accent to tint the Talk Mode side bubble (macOS/iOS/Android).
 - Nix mode: opt-in declarative config + read-only settings UI when `CLAWDIS_NIX_MODE=1` (thanks @joshp123 for the persistence — earned my trust; I'll merge these going forward).
 - Agent runtime: accept legacy `Z_AI_API_KEY` for Z.AI provider auth (maps to `ZAI_API_KEY`).
-- Groups: add per-group mention gating defaults/overrides for Telegram/WhatsApp/iMessage via `*.groups` with `"*"` defaults.
+- Groups: add per-group mention gating defaults/overrides for Telegram/WhatsApp/iMessage via `*.groups` with `"*"` defaults; Discord now supports `discord.guilds."*"` as a default.
 - Discord: add user-installed slash command handling with per-user sessions and auto-registration (#94) — thanks @thewilloftheshadow.
 - Discord: add DM enable/allowlist plus guild channel/user/guild allowlists with id/name matching.
 - Signal: add `signal-cli` JSON-RPC support for send/receive via the Signal provider.

 Clawdis starts Discord only when a `discord` config section exists. The token is resolved from `DISCORD_BOT_TOKEN` or `discord.token` (unless `discord.enabled` is `false`). Use `user:<id>` (DM) or `channel:<id>` (guild channel) when specifying delivery targets for cron/CLI commands.
 Guild slugs are lowercase with spaces replaced by `-`; channel keys use the slugged channel name (no leading `#`). Prefer guild ids as keys to avoid rename ambiguity.
