The seam-submit arm had grown three near-identical reject sites inline in
execute, each repeating "advance the escrow, then reject". resolveSeamOrder is
the single resolution point: escrow -> order frame, or a deterministic reject,
with the escrow advanced on every path exactly once.
That the escrow advances even on a reject is the load-bearing part, and it now
has one place to be true rather than three to stay true together.
