Wave Loop 776 closes #1487 by validating a module-scope [371][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.

What changed

  • Added scripts/gen_w776.py derived from scripts/gen_w775.py.
  • Generated specs/scratch/w776_bench_module_371x2p6_aos_var_call_write.t27 (23,744 elements, 759,808-bit packed vector, ~0.725 MiBit).
  • Added seal .trinity/seals/scratch_w776_bench_module_371x2p6_aos_var_call_write.json.
  • Added integration test accepts_w776_bench_module_371x2p6_aos_var_call_write.
  • Added closeout report docs/reports/FPGA_LOOP_CLOSEOUT_W776_2026-07-24.md with validation matrix, weak-point audit, 2025-2026 ternary/MVL literature scan, and W777 cooperation variants.
  • Updated docs/NOW.md, .claude/plans/wave-loop-777.md, .trinity/experience.md, .claude/skills/t27-wave-loop.md, and .trinity/current-issue.md.

What did NOT change

  • No changes to bootstrap/src/compiler.rs.
  • No changes to bootstrap/stage0/FROZEN_HASH (remains 68a0b933c00ba5efd7facb5997f00880c3eecae55e6ac5e8cea2aee399b92adc).
  • No changes to scripts/cocotb_ref_model.py.

Validation

  • cargo build --release -p t27c: OK
  • cargo test -p t27c --bin t27c: 1494 passed; 0 failed; 2 ignored
  • cargo test -p tri: 78 passed; 0 failed
  • cargo test -p t27c --test icarus_lowerable: 236 passed; 0 failed
  • t27c parse W776: PASS
  • t27c icarus-lowerable W776: PASS (lowerable)
  • t27c icarus-simulate W776: PASS (17 cycles, PASSED)
  • t27c icarus-cocotb W776: PASS (reference-model OK)
