Wave Loop 773 — [365][2]^6 Pt non-power-of-two outer-dimension array-of-struct variable from call with indexed signed writes

[gHashTag]

Goal
Close Wave Loop 773 by validating a module-scope [365][2]^6 Pt packed array-of-struct variable initialized from a function call, with indexed signed field writes and assert_eq read-back in a bench block.

Acceptance criteria

1. specs/scratch/w773_bench_module_365x2p6_aos_var_call_write.t27 is generated and parses.
2. The witness is Icarus-lowerable and simulates correctly (17 cycles, PASSED).
3. The cocotb reference model matches the t27 semantics.
4. t27c seal --save succeeds and FROZEN_HASH remains unchanged.
5. All cargo suites remain green.
6. Integration test accepts_w773_bench_module_365x2p6_aos_var_call_write is added.
7. Closeout report docs/reports/FPGA_LOOP_CLOSEOUT_W773_2026-07-24.md is written.
8. Learning is saved to .trinity/experience.md, memory, and skills-wave-loop-recipe.md.
9. Branch merges to master with Closes #1744.

Technical notes

• Shape: [365][2]^6 Pt where Pt = pub struct Pt { x : i16, y : i16 }.
• Total elements: 365 x 64 = 23,360.
• Packed vector width: 23,360 x 32 = 747,520 bits (~0.713 MiBit).
• MID_IDX = 182; frame-condition element [182][1][0][0][0][0][0] is element 182*64 + 32 = 11,680.
• Generator script: scripts/gen_w773.py (copy from scripts/gen_w772.py, set OUTER = 365 and MID_IDX = 182, manually fix the f-string header).
• Use assert_eq checks on changed elements (Icarus simulation path does not emit assert_ne).
• Include make_grid(32768) period-identity check because 32768 == 0 (mod 32768).
• Zero compiler / reference-model / FROZEN_HASH changes expected.

Cooperation variants for next Wave Loop

• Variant A (recommended): continue the odd outer-dimension ladder with [367][2]^6 Pt.
• Variant B: keep width at ~0.713 MiBit but move the packed var to bench/function scope.
• Variant C: add if-guarded indexed signed field writes at the current width.
