# Free sample — Sealed Pack Audit Checklist

**Skill ID:** `gf-ops-sealed-pack-audit`  
**Unlock:** $3.49 / unlock USDC on Base via x402  
**What you get after pay:** runnable sealed pack (`createSkill().run`) + workbook + templates  

## Summary

Audit checklist for x402 sealed digital packs: manifest integrity, unlock path, pricing metadata, and delivery smoke.

Before you sell sealed goods, audit them. Covers manifest hashes, unlock endpoints, USDC price fields, delivery artifacts, and buyer-path smoke. Free outline; x402 unlock for the full checklist. Not legal advice; no sales guarantees.

## When to use

- You are listing new sealed packs on a skill marketplace and need a pre-publish trust gate.
- Unlock flows, price metadata, or artifact zips have drifted from the catalog entry.
- You want a repeatable audit before each batch publish so buyers get what the listing promises.

## Decision-grade outline (free)

1. Verify pack identity: id, name, category, kind, and price_usd match catalog and payment metadata.
2. Check sealed delivery: artifact list exists, filenames match listing, and hashes or version pins are recorded.
3. Walk the unlock path: free outline visible, paywall/x402 challenge correct on Base USDC, success delivers the sealed assets.
4. Scan content policy: no revenue guarantees, no legal advice claims, disclaimers present where required by your standards.
5. Smoke as a buyer: complete a test unlock (or dry-run), confirm files open, and log residual defects before public sell.

## Capabilities

- Catalog-to-payment metadata parity checks for sealed goods
- Artifact inventory and integrity recording for delivery packs
- x402 unlock path walkthrough on Base USDC
- Buyer-path smoke and content-policy disclaimer scan

## Artifacts after unlock

- `sealed-pack-audit-checklist.md`
- `artifact-integrity-log.csv`
- `buyer-smoke-report.md`

## Detailed description

Selling sealed digital packs without an audit is how marketplaces ship empty zips, wrong prices, and broken unlocks. The Sealed Pack Audit Checklist is a trust good for operators of x402-style skill markets: confirm the listing tells the truth, the payment path works, and the buyer receives the files they paid for. Identity checks align id, name, category, kind, and price_usd between catalog JSON and payment metadata so a $4.99 listing cannot charge something else. Delivery checks require an artifact inventory, matching filenames, and recorded hashes or version pins so “sealed” means something concrete. The unlock walk verifies the free outline remains free, the x402 challenge on Base USDC is correct, and success actually delivers assets. A content-policy pass looks for banned guarantee language and missing disclaimers according to your house standards. Buyer smoke (live test or dry-run) opens the files and logs defects before the pack is public. Free outline on the listing; full sealed checklist unlocks via x402 Base USDC. This is operational QA guidance only—not legal advice, not a financial product, and it makes no revenue, conversion, or compliance guarantees. Use it as the last gate before batch publish.
