 - `agent/channels/github.ts` handles authorized mentions, `factory`-label intake, CI-failure follow-up, and PR summaries.
 - Failure comments are policy-controlled. `lib/failure-policy.ts` decides what a channel may say when a turn or session fails: a **deployment fault** (an unusable credential, an unpaid gateway account, or a model the account cannot reach) posts nothing, because only an operator can clear it, and every other failure posts one generic sentence that never carries the upstream provider's text. eve's built-in handler echoes that text verbatim, which is how a revoked key repeated `Model provider API error: Authentication Fails, Your api key: ****53a6...` into the originating thread on every dispatch.

+- `agent/channels/discord-mentions.ts` owns ordinary `@Computer` mentions in the internal Discord channel; `bridge/discord-gateway/` holds the Gateway connection that carries them, and `lib/discord-mention-policy.ts` decides admission. Admission is default-deny and fail-closed: an allowlisted guild, plus either an allowlisted channel or — with `DISCORD_INTERNAL_GUILD_WIDE` — an allowlisted operator role, plus an explicit bot mention with a non-empty prompt.
 - `agent/extensions/github.ts` mounts the official GitHub tools with an explicit allowlist and the WazooComputer GitHub App installation token.
 - `agent/subagents/` contains isolated station prompts, sandboxes, and handoff tools.
 - `agent/skills/` contains load-on-demand triage, writing, and tracker-bridging procedures.

 1. Create the Discord application and bot, and enable the privileged **Message Content** intent in its Bot settings. It is required for `content` to arrive at all; a socket that requests it without the portal toggle is closed with code 4014.
 2. Give the bot a channel permission set that can read and reply: View Channels, Send Messages, Send Messages in Threads, Read Message History, and Embed Links. No administrator permission is needed, and the `applications.commands` scope is no longer required.
 3. Leave the application's **Interactions Endpoint URL unset**. Discord is exclusive here: once a URL is configured, interactions stop arriving on the Gateway, so the approval buttons and modal answers a mention session waits on would go nowhere.

No `DISCORD_PUBLIC_KEY` is needed: nothing verifies an inbound interaction signature any more.
 5. Run the bridge on an always-on host, with the same allowlists, the same secret, and the deployment origin:
