A valid x402 manifest with 492 payment rails hit a D1 SQL limit — how to catch it before launch

说明与用途

本地和 CI 预检检查 x402 清单可防止数据库 SQL 错误，保留现有列表并确保安全更新。

问题

A merchant’s x402 manifest can be structurally valid yet fail during registry ingestion due to database SQL limits, risking data loss or incomplete updates.

结果

Implementing a local structural checker and CI preflight step prevents large manifests from causing database errors, preserving existing listings and ensuring safe replacements.

工作流

• 1. Run a local structural checker (ManifestScope) on the .well-known/x402.json to verify resource URLs, payment rails, and required fields.
• 2. Add the x402‑manifest‑import‑preflight GitHub Action to the merchant’s repo to run the checker on every push or pull request.
• 3. Configure the Action with "strict-warnings: false" to allow large but otherwise valid manifests to pass, or "true" to fail on advisory warnings.
• 4. If the Action passes, merge the PR; otherwise, fix the manifest and re‑run.
• 5. In production, ensure the registry uses parameterized set‑based insertion and wraps replacement in a single transaction to avoid partial updates.

证据

The registry failed with D1_ERROR: too many SQL variables

来源

Use parameterized set-based insertion rather than generating one huge batch with variable-length per-resource and per-payment statements

Add this to .github/workflows/x402-preflight.yml in the merchant's repository
