The 17e fixture's precondition asserted the clobber the guard removes — and being a require, its failure had the oracle dark: no divergence assertion ran. Re-pointed to 'delivered', with the residuals pinned where they happen: the id moves (which is why the class still fires), and direction reads the flip while the peer holds the old vote. The new reseed pin records the accepted cost: during the poison window the baseline misses the up the peer holds AND subtracts a down it never accepted, clamped to zero — served counts look healthy in both worlds, so SeedOursSubtracted/SeedBaselineClamped and the clamp log line are the only witnesses, and they are what the test defends.
