Diagnose upload:r2 403 Forbidden as R2 REST auth/account/bucket issue.

Date: 2026-08-13 00:22 Summary: Diagnose upload:r2 403 Forbidden as R2 REST auth/account/bucket issue.

[question] npm run upload:r2 → wrangler put 403 Forbidden on _pages/ar/privacy.html.gz

[try to solve] Cloudflare’s REST side rejected the R2 write—this is not a script logic bug. Local upload:r2:local is unaffected. On the machine, run wrangler whoami / r2 bucket list, confirm the bucket exists in the correct account; with multiple accounts, logout+login and clear wrangler-account.json. If using CLOUDFLARE_API_TOKEN, Object Read/Write is not enough for wrangler put—need Admin Read & Write, or switch to the S3 API. Handbook §9.1 added; upload script prints the same hint on 403.
