The model packet read chart.modules.dasha_boundaries, a key the engine never
wrote, so no answer ever had sub-period boundaries while the receipt still
reported precise timing as allowed. The server now cuts the running mahadasha
into antardashas out of the periods the packet already shows, exposes them as
their own evidence section, and precise timing requires that section.
A run whose calculation succeeded and whose model then wrote nothing was
answered with a fixed apology and billed as completed. It now asks once more
against the cached calculation, and fails with empty_answer—no charge—if that
attempt is silent too.
