OPEREX Engines
FOR DEVELOPERS & INTEGRATORSHeadless, deterministic, versioned computational APIs for industrial operations — built to be called over REST from your own systems, or consumed through an OPEREX UI module. One family, one contract style: typed I/O, an OpenAPI 3.1 description, and a pinnable engine + rule version on every response so a result is reproducible and auditable.
The engines
Deterministic continuous-operation crew rostering with a national labour-law compliance report — canonical rotation, holiday overlay, versioned rules. Signals and justifies, does not guarantee.
Shared principles
Same input plus the same engine and rule versions returns the same result — reproducibly, for audit.
Domain rules (patterns, statutes, catalogues) live as versioned data, separate from the engine core.
Where an engine touches compliance, it flags and justifies with sources — it does not certify.
