Vertical gap #5: lig-kernels.toml catalog + parity harness

Summary: Expand benchmarks/competitive/lig-kernels.toml to all lig.kernel.* catalog IDs (including md_force_short and heat_stencil_2d_f32 stubs), document cuda/hip/metal as N/A until emit env, and fix bench-lig-kernel-parity.sh to emit every registry kernel_id while keeping matmul smoke green.

Agent continuation

  1. Read — docs/game-dev/lig-kernel-catalog.md, benchmarks/competitive/lig-kernels.toml, scripts/bench-lig-kernel-parity.sh, packages/lig/li-tests/smoke/kernel_matmul_parity.li.
  2. Run — ./scripts/bench-lig-kernel-parity.sh; build matmul smoke from packages/lig/; ./li-tests/run_all.sh smoke (expects PASS compile_open_ok packages/lig/li-tests/smoke/kernel_matmul_parity.li).
  3. Then — WP2: wire import lig for package smokes; fill vendor columns when LIG_EMIT_CUDA|HIP|METAL=1 lowering lands.
  4. Blocked on — LKIR vendor emit (no timed cuda/hip/metal in TOML until then).

Changed

Area What Evidence
Registry 14 [[kernel]] rows aligned to catalog; meta emit_env_* benchmarks/competitive/lig-kernels.toml
Vendor honesty cuda/hip/metal = N/A on all rows catalog + TOML header comments
Harness JSON kernel_ids + per-kernel stub/pilot entries ./scripts/bench-lig-kernel-parity.sh
Smoke Standalone matmul pilot FFI smoke T-PKG-lig-kernel-matmul-parity compile_open_ok
li-tests Resolve packages/* manifest paths via $REPO li-tests/run_all.sh

Not changed

  • LKIR lowering / LIG_EMIT_* codegen — no compiler emit in this PR.
  • import lig package resolution from repo root — smoke uses inlined FFI shims.
  • benchmarks/competitive/registry.toml tier-1/2 CPU rows.
  • benchmarks dashboard vendor ratio ingest — N/A until emit env.

Breaking

None.

Security

N/A — registry metadata and smoke compile only.

Performance

N/A — stub registry; matmul pilot timing in local JSON only.
