Frontend Tier 1 Kitchen Sentinels

These fixtures are dedicated kitchen-sink cases for the frontend Tier 1 suite. They are intended as quick sentinels, not replacements for the full suites.

• pp_kitchen.c: object/function macros, token paste, conditional inclusion, stringify, variadics, and local include resolution.
• c_kitchen.c: declarations, struct/union/enum, arrays, pointers, loop, switch, object emission, and kit run.
• toy_kitchen.toy: tuple data, function pointer call, switch, JIT run, and interpreter run.
• wasm_kitchen.wat: memory, mutable global, loop/control flow, call, and kit run through the Wasm frontend. The Wasm sentinel also builds a small C pair to wasm32-none with build-exe and runs the produced .wasm.

Run one suite with:

test/tier1/frontend/run-kitchen.sh pp
test/tier1/frontend/run-kitchen.sh c
test/tier1/frontend/run-kitchen.sh toy
test/tier1/frontend/run-kitchen.sh wasm

Run all frontend sentinels with:

test/tier1/frontend/run-kitchen.sh all

The runner logs each fixture under build/test/tier1/frontend/<suite>/.
