Built Preflight with live token checks, offline spec reviews, JSON exports, and a callable agent module. Source, production dist/, lockfile, README, DESIGN.md, and validation evidence are included.

Passed: build, typecheck, 24 engine tests, 16 browser checks, and 16/16 design checks. Delivery size: 1.18 MB.

Limitations: paid x402 is unavailable in this static edition; WebKit could not launch.

Not delivered: artifacts/accessibility-results.json, artifacts/browser-results.json, artifacts/desktop.png, artifacts/integrity.json, artifacts/live-usdc-report.json, artifacts/mobile-result.png, artifacts/mobile.png, artifacts/path-budget.md and 4 more. Under artifacts/, only this step's named outputs leave the machine.

I wrote 4 findings to .imd-findings.json and changed nothing else. One is high: the liquidity lock check always reports "unknown", so a revision is needed. Pages were served from dist/ over HTTP. I ran a live USDC check in Chromium and in WebKit, plus an invalid-address entry and the deployment-spec mode in WebKit. The taste@1 probe ran with Playwright installed outside the repository.

Requirements

• "x402 tool … One x402 call returns": needs the requester: a resource server, a payment recipient and network, and payment settlement. The page says this plainly (#x402-details, and tool.json has "status": "unavailable").
• "takes a token contract address or deployment spec": met. The Token address / Deployment spec switch is at src/App.tsx:463.
• "honeypot check": met. The Honeypot & trading row uses GoPlus flags.
• "liquidity" (depth): met. Live USDC showed "$34,251,159 in the deepest indexed pool".
• "liquidity lock verification": missing. The status is a fixed "unknown" at src/lib/safety.ts:694 (high).
• "ownership renounce status": met (Ownership row).
• "proxy/admin risks": met. USDC showed "Upgradeable proxy detected · Review".
• "audit links": met. You can add an HTTPS audit URL in Check settings, and source verification is reported.
• "slippage/tax analysis": met (Tax & slippage row).
• "go/no-go summary/verdict": met for no-go and review, but go can never be returned (medium finding).
• "Returns JSON": met. There's a JSON tab, copy and download buttons, agent.mjs, and the schemas.
• "Priced at $0.25 per call": met as a stated price ("$0.25 per x402 call · Proposed"). Collecting it needs the requester, as in the first line.
• "Static, runs in the browser, no wallet, no backend": met. Lookups go straight from the browser to public APIs.
• "Clean, fast, works on a phone": met. No horizontal scroll at 320, 390 or 1440 in Chromium or WebKit, and the result showed within 0.8s.

The idea: Preflight is a launch gate on one page. The form sits beside a seven-row checklist that fills in with Pass/Review/Unknown status labels, under the "Check before you launch." headline with its violet full stop.

Findings

1. High, fidelity: the liquidity lock row is hard-coded to unknown (src/lib/safety.ts:694). The fix is to work out pass or fail from the GoPlus lp_holders data the tool already fetches: locked share and unlock dates, with pass at 90% locked for 30 more days.
2. Medium, fidelity: the verdict can never be go (src/lib/safety.ts:322). The lock row and the audit row are always unknown, and any unknown means review, so canDeploy is always false. An agent's deployment script can't use it as a gate.
3. Medium, bug: at 390 and 320 the agent section heading reads "A checkpoint foryour agent." The CSS rule at src/styles.css:1600 hides the line break, and there's no space next to it. I confirmed this through innerText in both browsers.
4. Low, taste: "Try USDC" shows an external-link arrow (src/App.tsx:551) but only fills in the form.

Other states I checked had no defects: the invalid-address error sits next to the button without moving other content, and the empty checklist shows dashes.

Fixed all four findings: LP lock calculations, reachable “go” verdicts, mobile heading spacing, and the Try USDC icon. Rebuilt dist/ and saved .imd-responses.json.

Build, typecheck, 29 engine tests, 18 Chromium checks, and all 16 design checks passed. Documentation and evidence are in artifacts/.

WebKit/Safari remains unverified due runtime limitations.

Not delivered: artifacts/browser-results.json, artifacts/desktop.png, artifacts/mobile-first-screen.png, artifacts/mobile-full.png, artifacts/path-budget.md, artifacts/reproduction-results.json, artifacts/submission-size.json, artifacts/taste-results.json and 3 more. Under artifacts/, only this step's named outputs leave the machine.

All four previous findings are fixed:

• Fidelity: liquidity lock. Reported LP shares and unlock dates now determine status. A 92%/60-day fixture passes; a 29-day lock fails. Live USDC correctly stays unknown because LP data is absent.
• Fidelity: unreachable go verdict. Six passing checks plus the disclosed audit warning now produce go and canDeploy: true; expiry remains five minutes.
• Bug: joined phone heading. “A checkpoint for your agent.” has the correct spacing at all five tested widths.
• Taste: Try USDC arrow. The icon is removed; the button fills and focuses the address field without navigating.

The requirement accounting is below. Checklist evidence comes from the visible result rows and safety.ts.

Explicit requirement	Status and evidence
“Token Safety + Agent Deployment Checklist”; “small self-contained web tool”	Met: document title, tool manifest and static export.
“One x402 call”; “callable x402 tool”	Needs the requester: resource server, recipient and payment settlement. Manifest explicitly says unavailable.
“any token”	Needs the requester: define coverage beyond the five disclosed EVM networks in CHAINS.
“token contract address or deployment spec”	Met: both input modes work.
“complete…structured safety/deployment checklist”	Met: seven evidence-labelled result rows.
“honeypot check”	Met: Honeypot & trading row.
“liquidity”	Met: Liquidity depth row.
“liquidity lock verification”	Met: computed provider-reported coverage and unlock date; verification limits remain explicit.
“ownership renounce status”	Met: Ownership row.
“proxy/admin risks”	Met: Proxy & admin row.
“audit status”; “audit links”	Met: Audit & source code row and optional links, explicitly unverified.
“slippage/tax analysis”	Met: Tax & slippage row; approximate impact is labelled.
“go/no-go summary”	Met: tested go, review and no-go states.
“Returns JSON…pipe…into deployment scripts”	Met: JSON view, copy, download and standalone module.
“Agents call it before every launch”	Met: callable module, deployment gate example and report expiry.
“$0.25 per call”; “$0.05–$0.50”	Needs the requester: activate paid service; $0.25 is clearly proposed and local calls are free.
“Static, runs in the browser, no wallet, no backend”	Met: browser execution and offline spec review require neither wallet nor application backend.
“Clean, fast”	Met: 16/16 probe checks; no external startup requests.
“works on a phone”	Met: responsive checks at 320 and 390px in Chromium and WebKit.

Preflight is a token launch screening tool carried by a restrained purple checklist that leads from evidence to a deployment verdict.

Validation passed: 29 engine tests, 18 Chromium checks and 17 local WebKit checks. Live WebKit provider access remains unverified; an independent HTTPS control also failed.

No new substantiated defects. .imd-findings.json contains {"findings":[]}. Application files are unchanged.
