## Core tables

| Table          | Purpose                                                |
| -------------- | ------------------------------------------------------ |
| `profiles`     | Per-user profile, created by `handle_new_user` trigger |
| `user_roles`   | Role assignments (`requester` / `reviewer` / `admin`)  |
| `wallet_links` | Maps Solana wallet address → Supabase user id          |
| `siws_nonces`  | Short-lived SIWS nonces (service-role only)            |
| `projects`     | Review project + routing config                        |
| `items`        | Items pending or completed review                      |
| `decisions`    | Reviewer actions on items                              |
| `learnings`    | Captured corrections for training                      |
| `api_keys`     | Per-project public API keys                            |
| `webhooks`     | Outbound webhook configs + secrets                     |

## RLS

All public tables have RLS enabled. Access is gated through the `has_role(user_id, role)` security-definer function — never store roles on `profiles`.

## Triggers

* `handle_new_user` on `auth.users` — inserts a `profiles` row, assigns default `requester` role, sets wallet-derived display name when the email matches `*@wallet.loopdesk.local`.
