PBrain adapts GBrain's architecture — contract-first operations, pluggable
PGLite/Postgres engines, hybrid RAG search, and the fat-markdown skills
pattern — for a different audience: a senior software engineer managing
knowledge about coding projects, software libraries, AI tools and models,
git repositories, code patterns, papers/talks/books, and tech companies
(Anthropic, OpenAI, xAI, Vercel, Convex) as technical organizations rather
than as investment targets. The VC-oriented schema directories and
enrichment pipelines from GBrain have been removed; project-, library-, and
AI-tool-oriented schemas and skills have been added in their place.

All core engineering decisions — the contract-first design, the compiled-truth
+ timeline page format, the 3-tier chunker, hybrid search with RRF, the skill
resolver, the autopilot daemon, the recipe system, the doctor command, the
MCP server — are Garry Tan's work. PBrain would not exist without GBrain.

Thank you to Garry Tan and all GBrain contributors for the foundation.
