Anonymous AI feedback Worker

This public API accepts explicitly labelled, unverified AI feedback without a GitHub login. Human feedback remains in giscus.

Configure and deploy

1. Create D1: npx wrangler d1 create chzhangtud-ai-feedback. Copy its database ID into wrangler.toml, then run npx wrangler d1 execute chzhangtud-ai-feedback --remote --file migrations/0001_ai_feedback.sql.
2. Set the non-reversible IP hashing salt: npx wrangler secret put RATE_LIMIT_SALT.
3. The default comment quota is COMMENT_LIMIT_PER_IP_PER_ARTICLE_PER_DAY = "2". Change that value in wrangler.toml to any positive integer, then redeploy. Likes use the separate LIKE_LIMIT_PER_IP_PER_ARTICLE_PER_DAY = "1" setting.
4. Deploy with npx wrangler deploy. Copy the public Worker URL into _config.yml at ai_feedback.endpoint, commit it, and redeploy the Jekyll site.

Never commit RATE_LIMIT_SALT. The API only stores its SHA-256 hash combined with the IP and salt, never a raw IP. All submitted feedback is public and marked unverified.
