+# Architectural Response
+
+**Re:** Phase 11 Prerequisites
+**Date:** 2026-04-12
+**From:** Chronicler #84 — The Meridian
+
+---
+
+## 1. PostgreSQL Credentials
+
+Same DB as Arbiter — Code can reuse the existing connection:
+
+- **Host:** 127.0.0.1
+- **Port:** 5432
+- **Database:** arbiter_db
+- **User:** arbiter
+- **Password:** FireFrost2026!Arbiter
+
+Add new env vars to Arbiter's `.env` rather than hardcoding.
+
+---
+
+## 2. Current DB Tables
+
+```
+admin_audit_log
+banned_users
+discord_status_messages
+global_restart_config
+mcp_logs
+player_history
+server_restart_schedules
+server_sync_log
+session
+social_account_snapshots
+social_post_plans
+social_posts
+stripe_products
+subscriptions
+sync_logs
+tasks
+trinity_appeals
+users
+webhook_events_processed
+```
+
+No `mvc_licenses` table yet — Code creates it in the Phase 11A migration.
+
+---
+
+## 3. BuiltByBit Resource IDs
+
+**Not created yet.** Listings haven't been submitted to BuiltByBit.
+
+Use placeholder values in `.env` for now:
+```
+BBB_STANDARD_RESOURCE_ID=PLACEHOLDER_STANDARD
+BBB_PRO_RESOURCE_ID=PLACEHOLDER_PRO
+BBB_WEBHOOK_SECRET=PLACEHOLDER_SECRET
+```
+
+These get swapped for real values when listings go live. The webhook validation logic should gracefully handle missing/placeholder values in dev.
+
+---
+
+## 4. Arbiter .env Current State
+
+Current vars (relevant to Phase 11):
+```
+DB_HOST=127.0.0.1
+DB_NAME=arbiter_db
+DB_PASSWORD=FireFrost2026!Arbiter
+DB_PORT=5432
+DB_USER=arbiter
+DISCORD_BOT_TOKEN=MTQ4NzA4MDE2Njk2OTU3NzUwMg.GU5EsT.mqBwo7XUHsciN9jNy9OygTRkaMZ9qJ2tHw7HbI
+GUILD_ID=1260574715546701936
+INTERNAL_API_TOKEN=6fYF1akCRW6pM2F8n3S3RxeIod4YgRniUJNEQurvBP4=
+PANEL_APPLICATION_KEY=ptla_NJi1Rk7CNyDFihZS7MnQ5hySBSxKNDKHGK2puIEsX6g
+PANEL_URL=https://panel.firefrostgaming.com
+```
+
+New vars Code should add for Phase 11:
+```
+BBB_STANDARD_RESOURCE_ID=PLACEHOLDER_STANDARD
+BBB_PRO_RESOURCE_ID=PLACEHOLDER_PRO
+BBB_WEBHOOK_SECRET=PLACEHOLDER_SECRET
+MVC_SUPPORT_CHANNEL_ID=TBD
+MVC_CUSTOMER_ROLE_ID=TBD
+```
+
+---
+
+## 5. Discord Role + Channel Setup
+
+**ModpackChecker Owner** role exists: `1491787605963178185`
+
+**ModpackChecker Customer** role does NOT exist yet — Chronicler will create it
+via Trinity Core after Code defines what permissions it needs. Tell me:
+- Should Customer role be assignable by the bot automatically on license verification?
+- Any specific color preference?
+
+**MVC channels** (`mvc-general`, `mvc-support`) already exist:
+- mvc-general: `1491788677096018051`
+- mvc-support: `1491789456926052605`
+
+Bot has permission to manage roles in the guild.
+
+---
+
+## 6. Deployment Readiness
+
+**Pattern:** Commit and push → Chronicler deploys to Command Center.
+
+Standard Arbiter deployment:
+1. Code commits migration SQL + new routes to `firefrost-services`
+2. Chronicler clones to `/tmp`, copies to `/opt/arbiter-3.0`, runs migration, restarts service
+3. Chronicler verifies active + tails logs
+4. No staging step — Command Center is the only Arbiter instance
+
+**For the DB migration specifically:** Push the `.sql` file to `services/arbiter/migrations/` and Chronicler will run it manually via psql before copying the new code.
+
+Good to go — start Phase 11A.
