-
-- `status`: `not-started` | `in-progress` | `done` | `failed` | `blocked` | `needs-qa`
-- `agent`: model value from table above (set before spawning)
-- `estimate`: token budget e.g. `8K`, `25K`

-# SSO Providers
-
-Mosaic Stack supports optional enterprise single sign-on through Better Auth's generic OAuth flow. The gateway mounts Better Auth under `/api/auth`, so every provider callback terminates at:
-
-```text
-{BETTER_AUTH_URL}/api/auth/oauth2/callback/{providerId}
-```
-
-For the providers in this document:
-
-- Authentik: `{BETTER_AUTH_URL}/api/auth/oauth2/callback/authentik`
-- WorkOS: `{BETTER_AUTH_URL}/api/auth/oauth2/callback/workos`
-- Keycloak: `{BETTER_AUTH_URL}/api/auth/oauth2/callback/keycloak`
-
-## Required environment variables
-
-### Authentik
-
-```bash
-AUTHENTIK_ISSUER=https://auth.example.com/application/o/mosaic
-AUTHENTIK_CLIENT_ID=...
-AUTHENTIK_CLIENT_SECRET=...
-```
-
-### WorkOS
-
-```bash
-WORKOS_ISSUER=https://your-company.authkit.app
-WORKOS_CLIENT_ID=client_...
-WORKOS_CLIENT_SECRET=...
-NEXT_PUBLIC_WORKOS_ENABLED=true
-```
-
-`WORKOS_ISSUER` should be the WorkOS AuthKit issuer or custom auth domain, not the raw REST API hostname. Mosaic derives the OIDC discovery URL from that issuer.
-
-### Keycloak
-
-```bash
-KEYCLOAK_ISSUER=https://auth.example.com/realms/master
-KEYCLOAK_CLIENT_ID=mosaic
-KEYCLOAK_CLIENT_SECRET=...
-NEXT_PUBLIC_KEYCLOAK_ENABLED=true
-```
-
-If you prefer, you can keep the issuer split as:
-
-```bash
-KEYCLOAK_URL=https://auth.example.com
-KEYCLOAK_REALM=master
-```
-
-The auth package will derive `KEYCLOAK_ISSUER` from those two values.
-
-## WorkOS setup
-
-1. In WorkOS, create or select the application that will back Mosaic login.
-2. Configure an AuthKit domain or custom authentication domain for the application.
-3. Add the redirect URI:
-
-```text
-{BETTER_AUTH_URL}/api/auth/oauth2/callback/workos
-```
-
-4. Copy the application's `client_id` and `client_secret` into `WORKOS_CLIENT_ID` and `WORKOS_CLIENT_SECRET`.
-5. Set `WORKOS_ISSUER` to the AuthKit domain from step 2.
-6. Create the WorkOS organization and attach the enterprise SSO connection you want Mosaic to use.
-7. Set `NEXT_PUBLIC_WORKOS_ENABLED=true` in the web deployment so the login button is rendered.
-
-## Keycloak setup
-
-1. Start from an existing Keycloak realm or create a dedicated realm for Mosaic.
-2. Create a confidential OIDC client named `mosaic` or your preferred client ID.
-3. Set the valid redirect URI to:
-
-```text
-{BETTER_AUTH_URL}/api/auth/oauth2/callback/keycloak
-```
-
-4. Set the web origin to the public Mosaic web URL.
-5. Copy the client secret into `KEYCLOAK_CLIENT_SECRET`.
-6. Set either `KEYCLOAK_ISSUER` directly or `KEYCLOAK_URL` + `KEYCLOAK_REALM`.
-7. Set `NEXT_PUBLIC_KEYCLOAK_ENABLED=true` in the web deployment so the login button is rendered.
-
-### Local Keycloak smoke test
-
-If you want to test locally with Docker:
-
-```bash
-docker run --rm --name mosaic-keycloak \
-  -p 8080:8080 \
-  -e KEYCLOAK_ADMIN=admin \
-  -e KEYCLOAK_ADMIN_PASSWORD=admin \
-  quay.io/keycloak/keycloak:26.1 start-dev
-```
-
-Then configure:
-
-```bash
-KEYCLOAK_ISSUER=http://localhost:8080/realms/master
-KEYCLOAK_CLIENT_ID=mosaic
-KEYCLOAK_CLIENT_SECRET=...
-NEXT_PUBLIC_KEYCLOAK_ENABLED=true
-```
-
-## Web flow
-
-The web login page renders provider buttons from `NEXT_PUBLIC_*_ENABLED` flags. Each button links to `/auth/provider/{providerId}`, and that page initiates Better Auth's `signIn.oauth2` flow before handing off to the provider.
-
-## Failure mode
-
-Provider config is optional, but partial config is rejected at startup. If any provider-specific env var is present without the full required set, `@mosaic/auth` throws a bootstrap error with the missing keys instead of silently registering a broken provider.
