Patrick Buckley 8effe656bb test(e2e): E5 hidden-retry — the fire guard's non-occurrence detector (#900)
The interactive mirror of coord's G5. A close-on-hide inside the retry's
2s arm window is the reachable way to make it fire against a down
transport, and the detector is a NON-occurrence counted at the fault
layer: history_requests must be unchanged across the hidden window.
Remove the OPEN term and the hidden fetch lands, stamping hidden1.

The scenario also pins the two rulings the guard leans on: the latch
must still be SET after the skip (a skipped retry heals nothing), and
the show edge alone must not heal it — a replay_ok reconnect carries no
synthetic state_change, so the repair rides a plain send's organic
settle into the transport-free backstop, which is why exactly one new
SSE open spans show + heal.
