Detailed Description

Layer 1 search mechanics and sign-off: the design that is scored is the design that is shipped.

L1-01  validation never raises tank pressure or swaps the candidate to make a design "solve".
L1-04  the derived throat is solved to tolerance, independent of where CMA proposed it.
L1-05  sign-off re-checks every declared geometric limit at face value.
L1-07  the block stage searches no derived DOF and uses per-coordinate scaling.
L1-08  valley escape fires only on the infeasible plateau, not on a shaping-term floor.
DEF-09 the chamber OD floor follows the smallest reachable throat, not the envelope cap.

Run Layer-1 setup up to the worker pool and return (bounds, constants).

◆ test_a_one_dimensional_block_does_not_crash_cma()

test_layer1_search_and_signoff.test_a_one_dimensional_block_does_not_crash_cma ( )

Dropping the derived DOFs can leave a block with one coordinate; CMA_stds on a 1-D
problem raised IndexError inside cma (seen on configs/ethalox_6500N.yaml, seeds 3 and 4).

◆ test_blocks_search_no_derived_dof_and_scale_per_coordinate()

test_layer1_search_and_signoff.test_blocks_search_no_derived_dof_and_scale_per_coordinate ( )

L1-07: blocks ran isotropic CMA (sigma = 0.2 x median span) over coordinates whose
ranges differ by 1e5 and searched the solved throat, eps and fuel pitch freely.

◆ test_derived_throat_is_independent_of_the_proposed_start()

test_layer1_search_and_signoff.test_derived_throat_is_independent_of_the_proposed_start ( )

L1-04: two secant steps from the proposal left +0.4..0.9 % thrust depending on the start.

◆ test_element_count_scan_crosses_basins_along_constant_injector_area()

test_layer1_search_and_signoff.test_element_count_scan_crosses_basins_along_constant_injector_area ( )

Seeds ended at n = 5, 5, 7, 13 with objectives 20 % apart: at fixed jet diameters each
count is a different injector, so an integer CMA step never crossed between them. Scored
along constant flow area and pitch circle, every count is reachable in one batch.

◆ test_od_floor_admits_the_shape_band_at_low_thrust()

test_layer1_search_and_signoff.test_od_floor_admits_the_shape_band_at_low_thrust ( monkeypatch )

DEF-09: the OD floor was 0.5 x cap -- a 72.9 mm bore under a 1 kN engine whose
D/Dt band (2.2-3.2) wants a 41-60 mm bore.

◆ test_signoff_enforces_the_declared_element_pitch()

test_layer1_search_and_signoff.test_signoff_enforces_the_declared_element_pitch ( )

L1-05: 24 doublets in a 127 mm bore is a 22.97 mm pitch against the 6500 N config's
22.5 mm limit; the 4.4e-4 squared miss hid under gate_eps and every seed said VALID.

◆ test_validation_does_not_boost_tanks_to_make_a_design_close()

test_layer1_search_and_signoff.test_validation_does_not_boost_tanks_to_make_a_design_close ( )

L1-01: the replay retried at 1.03-1.72x tank pressure, took the first that solved,
and stamped the design VALID with the un-raised pressures written to the YAML.

◆ test_valley_escape_ignores_a_constant_shaping_floor()

test_layer1_search_and_signoff.test_valley_escape_ignores_a_constant_shaping_floor ( )

L1-08: 'best > 100/150/300' read the ~1970-point mass floor as stuck on every 6500 N
run (7 sigma kicks) and never fired on blank runs.
