First Verifiable AI Architecture Analysis – Zero Source Files Read (github.com)

On October 24, 2025 the Open Cognition team published and demonstrated the first verifiable, pure-grounded architecture analysis where an AI produced a complete architectural understanding without reading any source files — reasoning solely from structured PGC (Grounded Context Pool) metadata. The demo reports: zero source files read, 101 structural patterns analyzed, all insights produced by reproducible command outputs (patterns analyze, blast-radius), and a meta‑cognitive capability to reason about its own architecture. The system is claimed to be production-ready and fully auditable: every transformation is logged, every artifact is content-addressed by cryptographic hash, and every claim can be re-run and verified. Technically, PGC is presented as an executable bounded lattice: knowledge elements live in objects/ (immutable content-addressable storage), index/ maps semantic paths to current hashes (the “present”), transforms/ records an immutable operation log (the “past”), and reverse_deps/ provides O(1) reverse lookups (the “nervous system”). Reasoning reduces to two lattice primitives — Meet (common dependencies via downward traversal) and Join (synthesized abstractions upward) — and an Update Function U that propagates invalidation efficiently through reverse_deps. Overlays (structural_patterns, lineage_patterns) anchor to the same genesis layer to produce specialized, verifiable views (architecture, dependency/impact). For AI/ML, this promises verifiable, hallucination‑free system knowledge, reproducible analysis at scale, and a formal, performant foundation for persistent model memory and auditability.
