Adds scripts/gateway-ping-g23.mjs, a manual check that sends one prompt through Factory's AI Gateway relay and prints the answer and the cost the gateway reports. It has the same shape as scripts/gateway-ping-c5.mjs. No test calls it and CI never runs it.

Acceptance

Entry	Change	Proof
Uses the ai devDependency pinned at 7.0.165; package.json and package-lock.json unchanged	scripts/gateway-ping-g23.mjs imports from ai	git diff --stat origin/main shows only scripts/gateway-ping-g23.mjs (1 file, +42)
Script creates the gateway with createGateway({ apiKey, baseURL: <FACTORY_GATEWAY_URL>/v4/ai }), calls generateText with nvidia/nemotron-3.5-lightning-free and Say ok., prints text: and cost:; on a missing variable or a failed call it writes one stderr line and exits non-zero; the key is never printed	scripts/gateway-ping-g23.mjs	the one manual run below; node --check scripts/gateway-ping-g23.mjs passes. The failure paths were reviewed in code only, because a second run would break the one-call rule.
Run once from the worker's shell; stdout quoted verbatim	n/a	see below
npm run check and npm test pass; the only change is the new script	n/a	Validation

The one run of node scripts/gateway-ping-g23.mjs (exit code 0)

stdout, verbatim:

text: ok
cost: 0

stderr had only Node's EnvHttpProxyAgent is experimental warning, which the sandbox's proxy setup triggers.

Validation

• npm run check: passed.
• npm test: passed, 855 tests, 0 failed.
• npm run test:db: not run here. Factory's validation runs it. This change adds no source file or test file.
• Budget command: none on the task card.

Fake-only proofs

none

Design checklist

n/a: the repository has no design checklist.

Assumptions

1. The script follows the shape of scripts/gateway-ping-c5.mjs: the stderr line is prefixed gateway-ping-g23: , the key is masked as *** if it shows up in an error message, and the HTTP status is added as (HTTP <status>) when the error has one.
2. When the gateway reports no cost, the script prints cost: undefined rather than failing.
3. npm run check only covers src/ and test/, so the script's syntax was checked separately with node --check. The script is not added to check, because package.json must not change.

Factory: validation green on cada341; ready for the reviewer.

[clockgrove-factory]

Factory reviewer: one comment-only pass, 1 comment(s).

Acceptance as the reviewer judged it:

• 1: met (The script imports createGateway and generateText from ai; package.json pins ai at 7.0.165, the installed version is 7.0.165, and the commit changes only scripts/gateway-ping-g23.mjs, so package.json and package-lock.json are untouched.)
• 2: met (Lines 25-28 build the gateway with the exact apiKey and baseURL expressions; line 29 calls generateText with nvidia/nemotron-3.5-lightning-free and Say ok.; line 31 prints text: and cost: from providerMetadata.gateway.cost; lines 22-23 and 32-38 write one stderr line naming …
• 3: met (The PR body reports one run with exit code 0 and quotes stdout verbatim (text: ok / cost: 0), which matches the two-line format line 31 writes; the run itself cannot be checked from the diff and was not repeated here, to keep the one-call rule.)
• 4: met (Rerun on the PR head: npm run check passed and npm test passed with 855 tests, 0 failed; git diff --stat shows one file changed, the new script (+42).)
