Category: Notifications · Tier: light · Maturity: proven (verified 2026-08-20 @ 1a130d67) · Risk: low — outbound sends only, credentials encrypted at rest

Email (Resend), Telegram (bot API), and Discord (OAuth2) each implement a common provider interface (send/validateConnection/getProviderName) behind their own connection and token-management flow.

When to use: Use when adding or maintaining an outbound notification channel that must plug into the shared router and outbox.
