**TL;DR:** 403 Forbidden covers two different situations: you exceeded a quota, or deletion protection refused a delete. Read which one before acting; the fixes are opposites. Fix: delete unused resources, request a limit increase from support, or restructure (namespaces instead of indexes). Fix: disable deletion protection on the index first, then delete.

## The fix

**TL;DR:** 403 Forbidden covers two different situations: you exceeded a quota, or deletion protection refused a delete. Read which one before acting; the fixes are opposites. Fix: delete unused resources, request a limit increase from support, or restructure (namespaces instead of indexes). Fix: disable deletion protection on the index first, then delete.

## The fix

1. **Quota.** Project or organization limits on indexes, pods, or usage. Creating beyond the cap 403s. Fix: delete unused resources, request a limit increase from support, or restructure (namespaces instead of indexes).

2. **Deletion protection.** The index has deletion protection enabled and a delete call was refused. Fix: disable deletion protection on the index first, then delete. This is a safety feature doing its job; do not script around it blindly.

3. Never auto-retry a 403. It is not transient.

4. Never disable deletion protection as a drive-by step in a cleanup script. That flag exists so a script cannot nuke production. Require explicit human confirmation naming the index.

5. After any quota fix, verify with `list_indexes` or the relevant describe call before re-running the original operation.
