+-- Migration 005: Personas
+--
+-- Adds the three `auth.personas*` tables introduced by the M2.a–c MCP
+-- work (feat commit 493db0c3b). See docs/plans/mana-mcp-and-personas.md
+-- for the full spec, and src/db/schema/personas.ts for the Drizzle
+-- definitions.
+--
+-- A `persona` is an auto-driven user (archetype + system prompt + module
+-- mix) that goes through the normal auth/register/JWT pipeline — kept in
+-- the auth schema so foreign keys to `auth.users` stay straightforward.
+-- The companion tables are append-only:
+--   - persona_actions: every MCP tool call the runner makes
+--   - persona_feedback: module-scoped quality ratings emitted per tick
+--
+-- This SQL matches what drizzle-kit push would emit for personas.ts. We
+-- apply it manually because the other tables created alongside personas
+-- (spaces.credentials, spaces.module_permissions) live outside the auth
+-- schemaFilter and pre-existing public enums would otherwise trip the
+-- push. See migration 006 for the follow-up that makes push clean.
+--
+-- Idempotent: re-running on a partially-migrated DB is safe.
