Define the evidence before drawing it.

Subticked publishes the architectural and methodological vocabulary behind its replay research. These notes describe the target system and do not imply that the player is currently available.

R01Time model

CS2 subtick time without invented substeps

Model exact replay instants using server tick, fixed-point intra-tick phase, and deterministic ordering.

Methodology · 8 min
R02Artifact architecture

Why the browser should never parse a demo

Separate Source 2 protocol change from the stable, signed replay contract consumed by the browser.

Architecture · 11 min
R03Trust boundary

Threat model for a browser replay workspace

Raw-source isolation, artifact signatures, resource ceilings, identity privacy, and bundle enforcement.
