Engineering Log: Antigravity Memory Architecture

Date: 2026-05-18 Topic: Hierarchical Memory vs. Native Capture

1. The Technical Problem

AI agents instinctively default to generic folder structures (docs/, engineering/) due to statistical weighting in training data. Fighting this “gravity” creates token overhead and friction.

2. The Architectural Solution: Tiered Memory

We are implementing a 2-tier filesystem memory model:

  • Tier 1 (Episodic/Native): Generic folders (docs/, notes/, engineering/) serve as the high-velocity “Capture Layer.”
  • Tier 2 (Semantic/Pillar): The 4-Pillar Scaffolding serves as the “Curation Layer” (The Brain).

3. Implementation Pathway

  • Promote the Engine to 00_core.
  • Establish ~/projects/GEMINI.md as the root context router.
  • Develop a “Curator Agent” to autonomously promote Tier 1 insights into Tier 2 pillars.

4. Model Strategy (2026)

  • Execution: Claude 3.5 / GPT-4o (High-speed vibe coding).
  • Curation: Gemini 1.5 Pro (Large context window for repository-wide synthesis).
