Plan section 2.4 records the re-scope (Q1, Q2, Q5 here; Q3 and Q4 to the sibling lanes) and
the operating changes (both boxes, nice 10, the capacity layer's yield, queued sweeps). The
sweep is shardable (--seed-start), writes every row as it lands, counts the Q5 structure
and draws from the F8 label space so the unmodified f8 harness (src/live.rs, built as
adv-live) measures the live hot set of the same program. Devnet 3 epoch-0 program.json
copied read-only as an input.
