A 3-Layer AI Memory Architecture: Obsidian Vault + Master Context File + Hub-and-Spoke
AiJohnAllen · x · 2026-11-16
Most founders babysit a chat window with amnesia: re-explaining their business, re-pasting offers, losing precision after 40 messages. The author proposes a 3-layer memory architecture:
- Plain-text local vault (Obsidian): keep business rules, ICP definitions, pricing, and pipeline in local Markdown files, not trapped in chat history;
- One canonical state file (00-MASTER-CONTEXT.md): a single <1,500-word structured key-value master file (offer:, icp:, activedeals:, nextactions:) auto-synced via Google Drive;
- Hub-and-spoke execution (Gemini + Workspace): treat chat threads as temporary RAM while the synced Obsidian vault remains the source of truth.
