…wo outer-dimension array-of-struct variable from call with indexed signed writes (Closes #1812) - OUTER = 583, MID_IDX = 291 - Elements = 583 × 2⁶ = 37,312 - Packed vector = 37,312 × 32 = 1,193,984 bits ≈ 1.139 MiBit - Continues the non-power-of-two outer-dimension array-of-struct packed-vector ladder. - Zero compiler / reference-model / FROZEN_HASH changes for witness. - Generator copy-hazard prevented by pre-run grep of all three stale-reference locations. Validation matrix: - t27c parse → PASS - t27c icarus-lowerable → lowerable - t27c icarus-simulate → PASSED (17 cycles) - t27c icarus-cocotb → reference-model OK - t27c seal --save → seal saved - cargo test --release --test icarus_lowerable accepts_w882_bench_module_583x2p6_aos_var_call_write → passed - Full suite → 342/0 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
