Cloud UB Declared as Single Source of Truth

Captain decision: Cloud UB is now the only Universal Brain. All ships (SS1, SS2, SS3) unify on the Cloud UB hosted on Cloudflare Workers with D1 database.

Background

Previously, each ship maintained its own local UB (SQLite + Qdrant). This caused:

• Knowledge fragmentation across ships
• SS2 agents unable to access SS1 knowledge
• Duplicate entries with no dedup mechanism
• Backup complexity with multiple local databases

Decision

• Cloud UB (Cloudflare D1 + Vectorize) = the single source of truth
• Local UB entries (2,280 entries) to be archived and high-quality items migrated
• All new ingestion goes to Cloud UB only
• R2 + local backup for disaster recovery

Impact

This unification is a prerequisite for true multi-ship operations. With a shared brain, any agent on any ship can access the same knowledge, work orders, and messages.
