feat(igla): Wave Loop 775 — module-scope [369][2]^6 Pt non-power-of-two outer-dimension array-of-struct variable from call with indexed signed writes

[gHashTag]

Wave Loop 775 closes #1485 by validating a module-scope [369][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_w775.py derived from scripts/gen_w774.py.
• Generated specs/scratch/w775_bench_module_369x2p6_aos_var_call_write.t27 (23,616 elements, 755,712-bit packed vector, ~0.721 MiBit).
• Added seal .trinity/seals/scratch_w775_bench_module_369x2p6_aos_var_call_write.json.
• Added integration test accepts_w775_bench_module_369x2p6_aos_var_call_write.
• Added closeout report docs/reports/FPGA_LOOP_CLOSEOUT_W775_2026-07-24.md with validation matrix, weak-point audit, 2025-2026 ternary/MVL literature scan, and W776 cooperation variants.
• Updated .claude/plans/wave-loop-776.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: 235 passed; 0 failed
• t27c parse W775: PASS
• t27c icarus-lowerable W775: PASS (lowerable)
• t27c icarus-simulate W775: PASS (17 cycles, PASSED)
• t27c icarus-cocotb W775: PASS (reference-model OK)

Notes

• W774 PR feat(igla): Wave Loop 774 — module-scope [367][2]^6 Pt non-power-of-two outer-dimension array-of-struct variable from call with indexed signed writes #1484 is still open awaiting review. W775 was branched from wave-loop-774 HEAD (433102763) so the odd-dimension ladder could continue without blocking.
• Traceability weak point persists: only ~16.2% of recent 30-day commit subjects carry Closes #N/Fixes #N, though bodies/closeouts still include the link.
