# Pre-outcome plan revision v1→v2

No capacity outcomes were computed under v1. The physical-calendar preflight failed systematically at DST transitions, and signed source solar values violated the initial nonnegative assumption. All source CSV bytes remain unchanged.

RTE’s June2025 specification describes fixed96quarter-hour source labels/day and half-hour actuals. Independent checks found all48actual(date,heure)labels complete for every nominal date, while derived UTC timestamps are non-injective in spring and omit an autumn hour. No repair is inferred.

v2changes the estimand to a labelled nominal-profile accounting model, preserving reported signed primary values, adding explicit nonnegative-generation and DST-date-removal sensitivities, and retaining the original exact-balance/monthly-permutation logic. The old physical-calendar plan and its ABORT record remain part of the research record. This cannot establish actual French physical storage capacity or falsify the source duration-aware mechanism.
