==========

The reference backend is dependency-free. Strict representation is the default
normalization profile; logical equality is opt-in. A matching fingerprint is
evidence for accidental drift detection, not proof against an adversary.

Run examples from the repository root. Source preparation, observations and
declared lineage remain separate evidence: a capture time does not establish
operation timing, and missing data must remain visible in reports.
