- only a substantive call after the close reopens a timer-closed incident;
a thin "10-4" (doesn't refresh updated_at) or a sweep link of a call from
before the close rides along without reopening — otherwise the next
sweep closed it again and the portal flickered.
- substantive_call_count counts a call once, not once per scene.
- a timer-closed incident is never adopted as a cross-system parent.
Replay e972cac (correlation-only on 731b54b's extraction) vs the 09-22
answer key: pairwise F1 0.548 -> 0.807 (precision 0.839 -> 0.956, recall
0.407 -> 0.698); the bridge MVA is one 76-call incident instead of two
40-call halves. server-26#170.
c2-core: 468 pass.
