Complete ODS documents from published sources and real systems, each with the mistakes a reader must refuse.
Each document is valid. Each entry in its refused.json plants one mistake in a copy of the document and names the findings a check must give. The checks are in Validation.
Two cases so far: a Directive 038 noise impact assessment and a Calculate propagation run. More come before the first release.
Cases
Calculate golden scene G1: flat grass, still air
A real run of a propagation solver: OpenCycle's Calculate labels on golden scene G1, run 20261111T191023Z-42c4ba035, accepted as the scene's baseline on 2026-11-11. The scene and its judging are Calculate's. The exact field is the Weyl-Van der Pol solution for a point source above a locally reacting ground (Salomons, Computational Atmospheric Acoustics, 2001), with the Delany-Bazley impedance of grass (Delany and Bazley, 1970). 94 records, 10 planted mistakes.
Directive 038 noise impact assessment
Alberta Energy Regulator, Directive 038: Noise Control (April 2, 2024), appendix 4, problem 2, with the estimate of appendix 2: https://static.aer.ca/prd/documents/directives/Directive038.pdf. 34 records, 23 planted mistakes.
