* fix(relay): stop taking the fleet-wide cell inventory lock on per-connection paths activateControl, acquireActivity, changeActivity and removeSupersededSameCellControls each adjust exactly one cell's reservation, yet took SELECT * FROM relay_cells FOR UPDATE, so every desktop rebind and phone reconnect in the fleet queued behind every other one and behind placement. They now use the single-row atomic update (or lock only their own cell row), leaving the inventory lock to placement and sweeps. Fleet-wide 55P03 retries ran p50 430 / p99 1320 per five minutes on 2026-09-03, every cell pinned sqlLatencyMsMax at the lock timeout, and the old cell image crashed on the resulting pool timeouts ~every 15 minutes. A real-Postgres test holds another cell's row and asserts a rebind proceeds; re-adding the inventory lock fails it. * fix(relay): lock the touched cell rows in order on cross-cell activity moves Review found that acquireActivity's existing-lease branch could lock the old lease's cell row (via removeActivityLease) before the new cell's row, which cycles with placement's ascending inventory lock; reproduced on real Postgres as paired 55P03 retries. lockCellRows now takes the one or two rows a per-connection path touches in cell_id order with the 500 ms request bound, and the census fails on any inline relay_cells FOR UPDATE outside the named lock helpers. A three-cell Postgres test moves an activity from the highest cell to a lower one while the target row is held and asserts the mover holds nothing else; five revert-mutants (inventory lock on each path, dropped ordering, dropped ORDER BY) fail it. * test(relay): make the inline relay_cells lock census scan whole statements Review showed two evasions: a FOR UPDATE inside query() and a queryLocked whose FROM relay_cells sat past a fixed line window. The guard now matches every query()/queryLocked() template statement in full; both evasions fail it. Also clears relay_cell_connection_snapshots in the connection- headroom Postgres suite so an aborted run does not poison the next.
