+The eleventh sweep landed at `ea1f836`. It is the first review of `2ac0843`
+-- `SizeRule` from an enum to a preferred length beside an independent bound,
+the offer constrained in `Placing::ask`, and `MaxSize` removed. Eight
+findings, the two largest being a hint read that answered "cannot say" above
+the diagnostics and so counted as no read at all, and five spellings of
+reading one environment variable across the rigs, which is the class the
+tenth sweep found one commit earlier -- there is now one `env` in
+`tests/rig/`, used by all six. `bounds_cost` also verified 128 regions inside
+its measured loop; the check moved out, and the 0.65% it measured is written
+beside it. `docs/LAYOUT_LOG.md` has all eight, with the two rules it tripped
+and left. Verified: format, clippy both ways, 206 and 210 tests, 400 depth-5
+trees warm against cold in 64.19s, and the cold dump byte-identical to
