Wave Loop 889 — module-scope [597][2]^6 Pt non-power-of-two outer-dimension array-of-struct variable from call with indexed signed writes

[gHashTag]

Closes #1838

This wave continues the mechanical packed-vector array-of-struct ladder one step past the 1.16 MiBit line.

• New spec: specs/scratch/w889_bench_module_597x2p6_aos_var_call_write.t27 — module-scope [597][2]^6 Pt variable initialized from a pure helper call, with indexed signed field writes and assert_eq read-back in a bench block.
• Generator: scripts/gen_w889.py copied from gen_w888.py with the copy-hazard checklist cleared (destination path, module header, MID_IDX).
• Integration test: accepts_w889_bench_module_597x2p6_aos_var_call_write added to bootstrap/tests/icarus_lowerable.rs.
• Seal: .trinity/seals/scratch_w889_bench_module_597x2p6_aos_var_call_write.json saved and verified.

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 --verify — all MATCH
• Targeted cargo test --release --test icarus_lowerable accepts_w889... — PASS
• Full suite: 348 passed; 1 pre-existing corpus_classifier_matches_lean_completeness mismatch for specs/cloud/railway_deploy.t27 tracked separately.

Zero changes to compiler, reference model, or FROZEN_HASH.
