Glossary
The definitive reference for Shift Craft | Atlas terminology and core architecture.
The Truth Protocol™
The immutable, single-source-of-truth architecture at the core of Shift Craft 2. It ensures that every shift assignment, user state and compliance check is mathematically verified against the central roster state, preventing 'blind' conflicts common in generic scheduling tools.
Compliance Firewall
Our real-time validation layer that sits between user actions and the database. It actively blocks any roster change that would violate Working Time Regulations (WTR) [e.g. 48h max average, 11h daily rest], Fatigue Index limits or specific site requirements. It acts as an operational safety lock.
Algorithm-Assisted Pattern Reconstruction (AAPR)
A proprietary import engine designed to ingest unstructured legacy data (Excel, CSV) and mathematically reconstruct the underlying repeating shift patterns (e.g., 4-on/4-off). It turns static data into active, predictable 'Master Roster' sequences.
Safety-Locked Scheduling
The operational state where a roster is mathematically guaranteed to be free of compliance breaches. In Shift Craft 2, you cannot publish a 'Safety-Locked' roster until all critical warnings are resolved.
Proprietary Scheduling Algorithms
Our custom-built mathematical models for solving complex 24/7 coverage requirements. Unlike generic 'calendar' tools, these algorithms optimize for specific industrial rotation logic (2 Days, 2 Nights, 4 Off) to eliminate gaps and minimize fatigue.
Deterministic Logic
A scheduling approach that rejects probabilistic or 'best effort' assignments. Our engine requires binary certainty for every slot. Staff are either valid and available or they are not. This eliminates the 'maybe' state that causes operational failure.
Master Roster
The authoritative, repeating roster structure from which all live schedules are derived. In Shift Craft | Atlas, the Master Roster defines coverage intent and rotation logic independently of day to day operational adjustments.
Coverage Integrity
The condition where every required post, role, or operational function is continuously staffed according to defined rules and coverage requirements.
Constraint-First Scheduling
A scheduling approach where legal, fatigue, and site specific rules are evaluated before any assignment is permitted, rather than corrected after the fact.
Roster State
The current validated condition of a roster, including assignments, compliance status, and unresolved constraints, evaluated against the Truth Protocol™.
Non-Negotiable Constraints
Rules that cannot be overridden by users, including Working Time limits, minimum rest requirements, and site mandated staffing conditions.
Operational Readiness
The condition where a roster is complete, compliant, and suitable for publication into live operations.
Governance Boundary
The enforced separation between what operators may adjust and what the system will refuse in order to preserve legality, safety, and audit integrity.
