read-width: packfile accepts a string-seed pack (any even-length hex epoch seed; the seed-word re-derivation still checks it); bench-only playbooks for the second PC round
Round 1 (run-readwidth-{5090,9070}-20261005) delivered the probes and refused every pack: pf_load demanded the chain's 32-byte epoch seed and the experiment packs carry igneum-pow --seed strings.
