 Before starting either process, the root commands check the Supabase schema. If it is missing and `SUPABASE_DB_URL` is configured, they transactionally create all D&G tables, functions, triggers, indexes, and policies from `supabase/bootstrap.sql`. Copy the **Session pooler** URI from the Supabase Dashboard **Connect** panel into the root `.env` and replace the password placeholder with the URL-encoded database password. The database URL is server-only and must never use a `NUXT_PUBLIC_` prefix.
 
+Existing campaigns are upgraded automatically to ruleset version 2 by `pnpm db:ensure`. The migration preserves every round, narration, current HP, inventory, and status; adds the SRD 5.2.1 character rules profile; and records one `migrate_ruleset` audit entry per campaign. Migrated characters retain compatibility with their previous proficiency hints, while newly created characters use explicit server-owned skill, expertise, and saving-throw proficiencies.

 The web and worker commands both load this root `.env` file explicitly. Environment variables supplied by Railway or CI take precedence over values in the file.
 
 The UI can be built without credentials. A running Nitro server and every worker process require `SUPABASE_URL`, `SUPABASE_SERVICE_ROLE_KEY`, `NUXT_PUBLIC_SUPABASE_URL`, and `NUXT_PUBLIC_SUPABASE_ANON_KEY`; startup fails with a clear error when required server credentials are missing. Redis is optional: when `REDIS_URL` is absent, the worker safely claims jobs from the Supabase `ai_jobs` outbox using short database leases and retries failed jobs up to three times.

+4. During world creation, the coauthor also creates three editable, universe-specific AI companions. A new campaign starts immediately with those companions and an owner-controlled hero. Additional players create a human character manually or ask the coauthor for an editable draft; owners can add more AI companions the same way.
 5. The owner creates an expiring private invite link. Signed-in email users join through `/join/:token`.
 6. Players save actions and mark them ready. The final ready action queues the round automatically; the owner can also continue without waiting.
 7. The worker resolves server-owned rolls and state, publishes narration, and opens the next round. Visible campaign tabs synchronize every two seconds and immediately when the tab regains focus.
