LAB · FIXTURE → RUNNER → RESULT → TRACE

From runnable to reproducible.

Every formal experiment pins its question, inputs, subject, and evidence boundary before publishing structured results and redacted traces. Synthetic format fixtures remain separate from experiment records.

Read the design before the result.

Controlled experiments support behavior only within their controls; Native, Controlled, and Adversarial evidence are never conflated.

TRACE LEDGER

Every run has its own evidence boundary.

A format fixture tests the data shape; only a reproduced run binds a formal experiment and result.
