A full sweep of #19, and the first review off48e04e. `Display for LayoutLen` leaves out every part that is zero, so `LayoutLen::ZERO` printed as the empty string -- and `Debug` forwards to `Display` since the last commit, so the four `assert_eq!`s in `cases/deferred.rs` print nothing where a request of zero is, and `scenario::describe` prints a `.width(0)` rule as `-`, which is what it prints for a widget that has no rule at all. That file exists so a tree a fuzzer found can be written out by hand; a value it cannot say is a hole in the one thing it is for. `Fixed::ceil_from_f32` took `next_up` of a `from_f32` that had already clamped, and `next_up` wraps, so a measurement past the top of the grid came back as the bottom of it. `from_f32` clamps deliberately because a float has further to come from; the ceiling is the other way in from a float and now holds to the same rule. The check goes beside the one `from_f32` already had. `Moves::depth` walked the move chain a second way, with its own copy of `CHAIN_LIMIT` and without the assertion `walk` makes; it is `walk` now, so the CPU counts the chain in one place and the shader's constant reaches both. `Harness::set_len` said it set a length "the way `.width()` sets one" and wrote the whole rule instead, dropping any bound beside it. A case that set a bound and then a length would have passed with no bound at all. Three rigs each spelled "one seed, or a range of them" by hand -- the class the eleventh sweep closed for reading a parameter and not for this. There is one `rig::seeds` now. `cases/deferred` was last in `suite.rs`'s otherwise alphabetical list. `diag::outside` writes out `AxisHolds::contains`'s four clauses to say which one refused a reuse; a debug assertion now catches a fifth clause added there and not here, which would leave a refusal counted and unexplained. `Sow::bound`'s comment recorded an open hole reached by seeds 4 and 196 at depth 5 -- but `generated.rs` says seeds stopped naming those trees when the leaves grew images, and 600 depth-5 trees over all sixteen cases agree warm against cold with every bound a fraction. The comment says what is true now and why the generator still grows pixels. Format, workspace clippy under -D warnings with and without layout-diagnostics, 208 ordinary and 212 diagnostic tests (207 and 211 before, plus the one this adds), and the cold dump byte-identical tof48e04eacross all 34,986 boxes. The three seed scans were not run: nothing here can move a box, which the dump confirms. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
