Calculation completion and decision authority are different states. A useful result may remain REVIEW, SCREENING ONLY, or TEST REQUIRED when its evidence basis is incomplete.

What version 1.1 adds

Tolerance, correction, and measurement planes

The guide separates the planes in which acceptance is judged, correction is performed, and the rotor is observed.

Machine/process capability

Calibration status is separated from task-specific minimum achievable residual, reduction ratio, angular capability, and correction limits.

Physical evidence floor

Vector repeatability across runs, starts, states, and reassembly is compared with the requested tolerance.

Assembly transfer

Component balance, final assembly balance, incremental correction, clocking, fixtures, and reassembly become different evidence claims.

Modal sensitivity and complete speed path

Critical-speed separation is joined with damping provenance, mode participation, acceleration, deceleration, resonance crossings, and dwell.

Reusable review tools

A worked fictional case, evidence-object template, freeze-readiness checklist, definitions, and verified retrieval path are included.

Who it is for

Engineering teams working with high-speed precision rotors, aerostatic or gas-bearing supports, balancing reports, rotor-dynamic screening, design reviews, technical due diligence, warranty attribution, and release decisions where a clean number is not enough.

The Field Guide is an engineering decision framework, not a standard, certification, or substitute for responsible release authority. Current standards remain the compliance anchors; historical and specialist literature is used as engineering-method support.
