Verification Taxonomy

The Four Classes of Number

VECTAC enforces an explicit evidence boundary. Automatic camera numbers are practice estimates based on observable head travel. Only an authorized human proctor can attest a test result. VECTAC never confers official military records.

Verification Class Origin & Sensor Source Practice History Projected Score Proctor Ledger Permitted Claim Official Submission
practiceEstimatedAutomatic On-device TrueDepth depth map or normalized face-scale tracker. Self-reviewed. YES YES (Projected) NO (until attested) Calibrated head travel or position time only. No form claim. NEVER
practiceManualSelfReported Direct participant manual keying without sensor validation. YES YES (Projected) NO Self-reported practice entry. No observer verification. NEVER
proctorAttestedManual Human proctor operating web/device timers, count controls, and audit notes directly. YES YES (Simulated) YES Human direct visual observation and attested repetition count. NEVER
proctorAttestedEstimate Paired athlete device proposes estimate; human proctor accepts or corrects on dashboard. YES YES (Simulated) YES Proctor attestation of a paired proposal. Sensor remains travel proxy. NEVER
Official Military Record Authoritative service branch personnel database & certified command test proctors. N/A N/A N/A External service authority. VECTAC cannot confer this status. OUT OF SCOPE

Push-Up Face-Travel Boundary

The camera sits face-up beneath the participant's head on the floor. When calibrated, it calculates the ratio $R = C / B$ of current closeness to baseline.

  • Permitted Claim: The head crossed the descent threshold ($R \ge 1.35$) and returned to top recovery ($R \le 1.15$).
  • Prohibited Claim: Elbow break angle, chest-to-ground depth, spinal alignment, or official form.

Plank Proximity-Zone Boundary

The timer samples distance timestamps and accrues valid hold time only while closeness remains within the valid proximity band $0.88 \le R \le 1.12$.

  • Permitted Claim: The head maintained calibrated proximity to the lens without collapsing or standing up.
  • Prohibited Claim: Back flatness, hip sag, buttock piking, or neck alignment.
