Targets render to an exact physical diameter of 25.0 mm across all displays using calibrated PPI presets. This standardizes visual angle and mouse travel across varied panel dimensions.

• Pure Visual: Single-stimulus optical motor reaction without auditory cues.

• Spatial Audio: Stereo-panned acoustic spawn triggers to train directional localization.

• Audit Hash: Cryptographic verification string generated upon set completion.

• Run ID: Session sequence ID bound directly to Discord embeds and CSV headers.

• Display Trace: Full resolution and calibrated PPI logged per block.

Sessions must be completed sequentially without aborting or restarting failed trials to record true physiological recovery.
