# Get a cycle's recálculo round chain

> The ordered Art.18 recálculo rounds for the cycle (oldest first), each projected verbatim — the excluded participant, the recomputed side + amount, the complement window (a later round surfaces the +15min prorrogation), and the internal resolution label — plus a note that any post-exclusion residual is a bilateral participant TED (surfacing, not routing). An unknown cycle is 404; a cycle that never entered recálculo is an empty chain.
