Start with the conclusion.
Then inspect the evidence.

What we know restates the strongest public evidence in everyday language. What remains unknown names the missing measurements. Why it matters explains which conclusion those gaps prevent.

This summary is a translation of the record, not a separate opinion. It must never turn an undisclosed value into an estimate.

Evidence marks identify provenance, not a robot score. Independent measurement, operator corroboration, manufacturer reporting and capability claims answer different questions.

A customer statement may establish that work happened at its site. A controlled independent test may establish a measured characteristic. Neither automatically proves years of reliable autonomous field operation.

Not disclosed means HumanoidUptime found no qualifying public value in the sources reviewed through the stated evidence date. It does not mean zero, poor performance or that the operator lacks private measurements.

The disclosure table is therefore a map of public knowledge. It is not a leaderboard.

Numbered references connect each material claim to its original sources. The timeline preserves when claims appeared, and the revision metadata shows when the public record itself last changed.

If a newer source supplies a missing denominator, corrects a figure or changes the evidence level, the record can be revised without erasing its history.
