Identity sheet

Field journal, precision instrument

Natural-history editorial warmth over forensic exactitude. Status is always carried by words and symbols — never by color alone.

The mark

An original geometric canary: a spine stroke, a wing of parallel strokes, and a tail. The same strokes recur as probe-path branches and excerpt brackets — the feather becomes a trace.

Typography

Newsreader display italic

Source Sans 3 carries interface and explanatory prose — quiet, legible, and warm enough to sit beside the serif.

Status grammar

PassedFailedErrorNot runUnknown

Passed, failed, not run, and unknown are distinct states and are never merged. A silent canary does not automatically mean a false claim.
