Agents routinely spend turns tight-polling for a condition that was already
going to notify them — ~80 consecutive no-op turns waiting out one local:gate
run on #2250, with a completion notifier for that very process already armed.
The convention existed only in a per-user memory note, which is invisible to
anyone else and cannot be relied on mid-session.
- AGENTS.md gains a "Waiting on long-running work" section: arm a notifier and
stop; one notification is a backgrounded command or a single `until` loop, many
is a Monitor. It states the one genuine exception — state the harness cannot
observe — and says where the poll belongs in that case, inside one backgrounded
loop rather than spread across turns.
- pre-push-gate points at it where the gate is actually run.
- pr-flow §7 points at it where the Copilot review is actually waited on, with
the loop written out. The count-not-existence trap is called out: on round two
the first round's review is still there, so `-ge 1` returns immediately.
