One hardening opportunity: exists() (fintual/backend-devops-interview/go-service/store.go:225)
  concatenates a table name. Every current caller supplies the literal blog_user or blog_post, so it is
  safe today. An explicit allowlist would protect against future misuse.


Please do it

I’ll add the table allowlist, check the Go tests, and commit the change. I’m applying the unslop skill for concise reporting.

Added an explicit allowlist to `exists()`: only `blog_user` and `blog_post` are accepted. Other names return an error before querying.

Added regression coverage; `go test ./...` passes.

Committed as `c558b0e`.
