WordPress bench Lab runner cannot load WP Codebox runtime-core recipe builder

[chubes4]

Summary

Homeboy Lab WordPress bench offloads are failing before workload execution because the WordPress extension cannot load a WP Codebox runtime-core module exporting buildWordPressBenchRecipe.

This blocks running newly merged WooCommerce checkout guardrail rigs against candidate branches.

Observed Failure

Command shape:

homeboy bench --rig woocommerce-performance \
  --path /Users/chubes/Developer/woocommerce@fix-checkout-create-order-idempotency/plugins/woocommerce \
  --scenario checkout-concurrent-create-order \
  --iterations 1 \
  --shared-state /tmp/woocommerce-old-fix-guardrails-concurrent \
  --setting-json 'bench_env={"WC_CONCURRENT_CHECKOUT_ITERATIONS":"1","WC_CONCURRENT_CHECKOUT_REQUESTS":"2"}' \
  --json-summary

The command offloads to homeboy-lab, prepares WooCommerce dependencies, then fails before the workload runs:

Error: WP Codebox recipe builder export buildWordPressBenchRecipe is unavailable.
Install/build a WP Codebox runtime-core module that exports buildWordPressBenchRecipe.
Pass --setting wp_codebox_core_module=/path/to/wp-codebox/packages/runtime-core/dist/index.js, or set HOMEBOY_WP_CODEBOX_CORE_MODULE to that built ESM entrypoint.
Fallback discovery also checks sibling wp-codebox checkouts for packages/runtime-core/dist/index.js.
This is separate from HOMEBOY_WP_CODEBOX_BIN / wp_codebox_bin, which only selects the wp-codebox CLI.
Homeboy Extensions no longer falls back to bundled WP Codebox recipe builders because that stale local copy can drift from the Codebox recipe contract.

Expected Behavior

The Lab runner should have an explicit, stable WP Codebox runtime-core recipe builder available to WordPress bench workloads, or Homeboy should fail preflight with an actionable setup/refresh path before creating a persisted bench failure.

Impact

This currently blocks verification for:

• Add true concurrent WooCommerce checkout rig chubes4/homeboy-rigs#256
• Add WooCommerce checkout gateway compatibility matrix chubes4/homeboy-rigs#257
• Add checkout create_order side-effect guardrails chubes4/homeboy-rigs#258
• WooCommerce PR Fix checkout order creation retry idempotency woocommerce/woocommerce#65588

The guardrail code is installed and discoverable, but iterations remain 0 because the recipe builder fails before workload execution.

Acceptance Criteria

• homeboy bench --rig woocommerce-performance --scenario checkout-concurrent-create-order ... reaches the WooCommerce workload on homeboy-lab.
• homeboy bench --rig woocommerce-performance --scenario checkout-gateway-compatibility-matrix ... reaches the WooCommerce workload on homeboy-lab.
• Missing or stale WP Codebox runtime-core setup is caught by homeboy rig check or an explicit extension setup/doctor command.
• The fix does not restore the stale bundled recipe-builder fallback.

Verification:

Lab setup evidence:

• Installed the extension PR branch on homeboy-lab through homeboy extension install --replace, source revision 486d8e54.
• Setup configured runtime-core at /home/chubes/.cache/homeboy/wp-codebox/source/packages/runtime-core/dist/index.js.

Blocked command reruns:

• checkout-concurrent-create-order reached WooCommerce workload execution on homeboy-lab; it no longer fails at WP Codebox recipe-builder load. Persisted run: d733c9a3-18cf-4f03-ab59-0d353c380984. Current failure is inside the workload: Checkout side-effect guardrail failure: public_create_order_does_not_set_order_awaiting_payment, legacy_coupon_independence, plus SQLite delete-join diagnostics.
• checkout-gateway-compatibility-matrix reached workload execution and passed. Persisted run: e1826aae-ea7c-4276-8e47-b5fba7e3bf3a.
