In one minute

• mu is the company chart of piabrota, an open software fabric made in Rio de Janeiro. It holds the dogma, the charter, the standards, the journal and the tools that every piabrota project inherits, and its eight products as submodules.
• DOGMA.md holds the ten invariants. Agents fix every error a user or an owner reports, in short pull requests. Judgement is decision-oriented: evidence, a decision model, calibrated probabilities, rules that humans define, a verdict.
• PIABROTA.md indexes every public repo of the org.
• pirsig will manage this repo: smart notes, PARA and a track record of high-level decisions. brain/ is its fork state.
• mu began as a copy of Ouroboric's company repo. NOTICE.md keeps that credit.
