Tyre C2: DownstreamTarget::OpenSpillway added — success (open low ground,
complete carved path) split from EdgeUnreachable (strict search exhaustion);
both doc comments exact; test updated. Tyre C3: determinism docstring
corrected (no BTreeMap; the endorheic f64 gate stated as deterministic-by-
derivation). Hoshe H1: vacuous cliff_edge test replaced by
single_basin_bowl_never_carves_a_gorge asserting the known-empty outcome.
Hoshe H2/H3: courses-force-empty disclosure at rect_window_replica and in
the results doc; courses.len() print added to the square production-fn
bench — measured 3/6/10 courses in window (NOT courses-empty, verified
twice); 'faithful stand-in' claim retracted for a precise scope statement;
GJ1c 18-course run identified as the sole production-density rate. Tyre C1:
appendix (4) headline rephrased — the tagged-envelope migration cannot be
dodged by payload optimization (byte math), field-count-rule trigger is a
workshop synthesis call; appendix (2) scope split per-shape.
Hydrology unit suite 15/15; atlas lib suite 679 green; benches compile.

cargo fmt across the four new files; needless_range_loop x2 (enumerate /
iter_mut) and identity_op in hydrology_equilibrium.rs. cargo test was green
on the bounced push — lint-only fixes.

bmv_gridunit_bench: production build_district_window_layer par_iter path at
330K/2.07M/8.3M cells (throughput holds, ~190-220 ns/cell parallel), block
(128m) and tile (1m/4m) spacing costs, the 83K-cell deepest-step viewport
shape, and the verified zero-savings octave-cutoff finding below District
spacing. wire_encoding_bench: real GJ338Bd derived canvases through
derive_at_metres, five encodings (raw rmp / bit-packed / RLE / PNG-per-field
/ PNG-of-packed) with measured bytes + encode/decode round-trips; corrected
raw density 6.00 B/cell. All #[ignore]d release tests.
Workshop gate measurements (2)(3)(4) for body-map-viewer.
