The seven principles the author distilled include: every conclusion needs a citation; memory is scoped per person; the past is versioned rather than rewritten, and deletions must issue a receipt; the agent proposes and the human disposes; the graph is the foundation rather than a feature, and the product should honestly stop when it is disconnected; show the points lost, since a benchmark that hides its zeros is marketing while one that records its zeros is evidence; do not assert on LLM prose, assert on structured data.
