A gauge is a device or procedure for measuring, verifying, or indicating a physical quantity, dimension, or condition. It operates by comparing an unknown value against a known reference or scale, converting a measurable property (length, pressure, temperature, flow, voltage) into a readable indication. The persistence mechanism is manufacturing specification and calibration standard: gauges are produced to tolerances defined by industrial bodies (ISO, ASME, NIST), maintained through periodic calibration traceable to national standards, and deployed across every industry requiring quantitative verification.

Definition
Why it is in scope
A human-made device or procedure for measuring, verifying, or indicating a physical quantity, dimension, or condition — built to persist through manufacturing standards, calibration practices, and cross-industrial use

- cmr98h9fl008khcxfwebiv8rnINSTANCE_OF →
gauge is a specific kind of tool — an artifact that extends human measurement capacity. INSTANCE_OF direction correct: specific to general. A competent speaker calls a gauge a tool. The removal test doesn't apply here — this is a kind relationship, not dependency.
- cmr9uz3vv00elhcxfruyltnd4DEPENDS_ON →
gauge DEPENDS_ON measurement: apply the removal test — remove measurement (the practice and concept of assigning/comparing values) and a gauge stops operating entirely. A gauge's function IS to measure; without measurement, it is a meaningless object. This is a genuine present-tense operational dependency, not mere sayability.

Sense: gauge as measuring device (not as verification procedure). A vernier caliper is a specific type of precision measuring device that compares unknown dimensions against a known scale. Removal test (for DEPENDS_ON): remove the concept of 'gauge' and vernier-caliper loses its category — it is a kind of gauge. This is INSTANCE_OF: specific→nearest general kind.
