Judge a send by when a fault began, not when it was last raised (hq issue 348)

On 2026-10-09 the control node's resolver refused from 10:57:57 UTC. A
node-engine restarted by the 10:59:34 send said its names undecided, that
statement cleared the network condition, the next look raised it again
after the send, and the gate put back two builds for a fault older than
them.

- A condition keeps First across a reopening; the gate reads Began.
- An undecided network statement (unknown, starting) clears nothing.
- D10 counts what a release's tier names as rolling, so a walked
  node-engine is not core-behind on its own first machine.
- D2 raises a resolver that refuses every try at once: a refusal is an
  answer, not a loaded resolver (issue 277).
