Edit opening stock or correct closed_at
On an open period: updates opening_quote / opening_fx (quote desks) or opening_local (local desks). Recalculates live WAC, remanente, and spray from the new opening plus current lines. Does not rewrite other periods or touch treasury. 409 PERIOD_CLOSED if you send opening fields on a closed day — reopen first. On an already-closed period: optional closed_at late-close correction (does not rewrite the frozen snapshot). Must be >= opened_at and must not overlap another period. After correction, the next period may open at exactly this closed_at.
