Abstract
Short-term test-retest reliability of the 10-metre fast walk test (10mFWT) and 6-minute walk test (6MWT) was evaluated in 31 ambulatory children with cerebral palsy (CP), with subgroup analyses in Gross Motor Function Classification System (GMFCS) Levels I (n=9), II (n=8), and III (n=14). Sixteen females and 15 males participated, mean age 9 years 5 months (SD 3y 7mo, range 4y 3mo-18y 2mo). Twenty had spastic diplegia, while the others had another form of CP. Retest interval varied from 1 to 4 weeks (mean 10.6d [SD 6.4]). Intraclass correlation coefficients (ICCs) estimated reliability. The 10mFWT ICC was 0.81 (95% confidence interval [CI] 0.65-0.90) across participants, and >0.59 in GMFCS subgroups (95% CI lower bound >0.01). The 6MWT ICC was 0.98, and >0.90 in GMFCS subgroups (95% CI lower bound >0.64). Bland-Altman plots indicated bias towards higher 6MWT retest distances in GMFCS Level I. Minimum detectable change (95% CI) was 61.9, 64.0, and 47.4m for the 6MWT within GMFCS Levels I, II, and III respectively. The conclusion is that while the 10mFWT showed inadequate test-retest reliability given its wide 95% CI, the 6MWT demonstrated good to excellent reliability. Investigation of the need for a practice walk when administering the 6MWT with children in GMFCS Level I is recommended to establish their fastest pace.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
