# List contingency schedule changes

> The operator-recorded contingency schedule changes, keyset-paged newest announced first. Each row is an out-of-band-received Núclea announcement (OP002 §14 = telephone/e-mail) recorded verbatim by an operator (decision #1); br-siloc parses no Núclea schedule wire and computes no schedule (D-4). Read-only — the feed is projected, never mutated through this surface.
