Makes the WebLanding 'Sign up' button work (it was 404ing — the tripit-enrollment flow didn't exist). Open passwordless registration: prompt(email,name) -> user_write(INACTIVE, external, group 'TripIt External') -> email verification (activates) -> passkey -> login. The inactive-until-verified gate is the security boundary: tripit trusts X-authentik-email, so activation must require proving inbox ownership. Passwordless login already works via the built-in webauthn flow. tripit-recovery (email -> new passkey) is built but intentionally NOT wired into the global brand recovery, so admin recovery is unchanged. Schema validated with terraform validate.

Viktor wants people outside the homelab to self-register to TripIt with email + a passkey (no password), kept separate from the rest of the homelab. Adds the empty, parentless 'TripIt External' Authentik group and a first-position branch in the catch-all policy that admits those users to tripit.viktorbarzin.me only and denies every other forward-auth host. Inert on apply (group empty => matches no existing user => no lockout). An adversarial review found the fence is forward-auth-only, so the runbook records the OIDC-app containment audit (every sensitive app already requires a trusted group External users won't hold), the Vault->Allow Login Users binding that closes the one open OIDC app, the SMTP prerequisite for email verification, and the before/after access-matrix verification. Flows/SMTP/Vault binding are UI steps per the runbook; the push that applies the catch-all edit must be human-watched (CI auto-applies the authentik stack).
