What is Writing telemetry?
Writing telemetry is metadata captured during composition — keystroke timing, pause durations, revision events, paste sizes, and session boundaries — recorded without storing the content itself.
Telemetry is the raw material of behavioral certification. A capture layer in the editor observes events as they happen and batches them for analysis: when keys were pressed (not which), how long pauses lasted, where text was deleted and rewritten, and how much arrived via paste.
The privacy boundary is the defining design constraint: timing and structure are recorded, content never is. A telemetry stream cannot reconstruct a single word of the document, but it can establish beyond reasonable doubt whether the document was typed by a human or pasted into existence.
Keystroke dynamics
Keystroke dynamics is the analysis of typing rhythm — the timing between key presses, pause patterns, and bursts — which is distinctive enough to characterize how a specific piece of text was physically produced.
Behavioral certification
Behavioral certification proves content origin by recording the creator's behavior during creation — typing rhythm, pauses, revisions — and issuing a signed certificate, instead of classifying the finished output.
