# Study 000C Abstract

This exhaustive full-data program analysis was conducted after completion of `Study 000A`, `Study 000B`, `Microstudy A`, `Microstudy B`, and the full-system audit. Its purpose was to test whether the corrected full dataset overturned any of the major program claims or instead sharpened them.

Using bundled flagship outputs, microstudy outputs, yearly ecology tables, and the raw-summary hybrid-cardio audit, the study evaluated claim stability, corrected conditioning ecology, hybrid-session placement within flagship windows, and temporal separation between later outdoor probe runs and later hybrid cardio blocks.

The corrected full-data pass did not overturn the core running findings. The flagship adaptation pattern remained phase-structured, turnover-led, and selectively rather than uniformly remodeled. Cadence still accounted for `62.42%` of cadence-stride speed gain, while `vertical_ratio_pct` remained the lowest-variability candidate at `2.14%` monthly CV and `vertical_oscillation_cm` remained the lowest-variability direct mechanics candidate at `4.19%`.

The biggest new content was ecological. The audit found `18` plausible GPS-bearing `indoor_cardio` sessions and `4` plausible GPS-bearing `strength_training` sessions. The early flagship window contained `7` hybrid indoor-cardio sessions totaling `9.45` miles and `4.99` hours, while the late flagship window contained `0`. In yearly corrected ecology, hybrid GPS cardio accounted for `4.20%` of 2025 indoor-conditioning hours and `26.34%` of 2026 indoor-conditioning hours, though the 2026 block ended on `2026-01-30` and sat `69` to `109` days away from the later outdoor probe runs.

The strongest corrected conclusion is therefore narrower and stronger at the same time: the program supports selective adaptation through corrected ecological narrowing into later stabilized running specialization, with turnover preserved more successfully than stride expression and with mixed internal cost rather than pure economy.
