THE METHODOLOGY RECORD

Build Log

This is the build-in-public record of how the oversight system that supervises the agent was designed and iterated. Each entry covers an engineering decision — what changed, why, and what the tradeoffs were. The trades are in the Ledger; this stream is about the rails that govern them.
