Preface

Most knowledge systems are optimized for publication. They store the polished answer, the approved policy, the current model, or the final report. This is useful, but incomplete. Once the answer has been separated from the path that produced it, later readers cannot reliably inspect what was observed, what was inferred, what remained uncertain, what alternatives were rejected, or why a revision became necessary.

QLens was conceived to preserve that missing path.

It is not merely a note-taking format, a documentation theme, a database schema, or a command-line application. Those are implementations. QLens is first a discipline: a way to let evidence challenge understanding while preserving the history of that challenge.

This Foundation Book states that discipline in durable terms. It is intentionally implementation-independent. A future QLens may use different storage engines, interfaces, programming languages, or presentation systems. It remains QLens only while it preserves the commitments described here.
