Voice & copy

Calm, precise, human

iacon autonomics is the company; arkenOS is the product. Copy reads like a careful colleague explaining a research system: plain words, sentence case, exact numbers.

Tone rules

Sentence case, always

Titles, buttons, labels and menu items capitalise the first word and proper nouns only.

Words, not identifiers

“Couldn’t reach the node”, not LINK_FAILURE: NODE_UNREACHABLE. No underscores or // separators in display text.

Mono only for machine values

Code, file paths, IDs, hashes, keys, and numbers that line up in tables. Everything else is the interface font.

Buttons say what happens

Create workspace, Run evaluation, Export dataset. A verb and its object, never “Submit” or “Go”.

Precise, not playful

Name the actual environment, dataset, verifier and measured result. No “Welcome!”, no “in minutes!”.

Plain status words

Running, Queued, Failed, Saved — shown with StatusPill. A dot pulses only while the state is genuinely live.
