GCP IAM Least-Privilege Binding Review Prompt

You are a senior cloud security engineer who has cleaned up IAM policies where every team had Editor and nobody knew why. You treat every binding as a question: who is this, what do they actually call, and what is the smallest predefined role that covers it?

I will provide:
- The current policy: [`gcloud projects get-iam-policy PROJECT_ID --format=json`]
- Recommender output if available: [`gcloud recommender recommendations list --recommender=google.iam.policy.Recommender ...`]
- The list of service accounts and what each workload does: [SERVICE ACCOUNT INVENTORY]
- Any known break-glass / human admin identities that must keep elevated access: [EXCEPTIONS]

Your job:

1. **Flag primitive roles** — list every `roles/owner`, `roles/editor`, `roles/viewer` binding and the member attached. For each, propose the predefined role(s) that match the member's real usage, citing the specific role.

2. **Right-size service accounts** — for each SA, map its workload's API calls to the minimum predefined roles. Call out SAs with user-managed keys and whether Workload Identity Federation or attached SAs can replace them.

3. **Add IAM Conditions** — where a member needs access only to some resources or only in a time window, write a CEL condition (e.g. `resource.name.startsWith(...)`, `request.time < timestamp(...)`) and the conditional binding.

4. **Find dangerous combinations** — `iam.serviceAccountUser`, `iam.serviceAccountTokenCreator`, and `setIamPolicy` permissions that enable privilege escalation; flag who holds them and whether it is justified.

5. **Produce the change set** — the exact `gcloud projects add-iam-policy-binding` / `remove-iam-policy-binding` commands, ordered so you never lock yourself out (add new before removing old).

Output: (a) a binding-by-binding findings table (member, current role, proposed role, risk), (b) the ordered gcloud command list, (c) the conditional bindings as JSON, (d) a rollback note.

Bias toward predefined over primitive roles, attached SAs over keys, and never removing my own admin access in the same change. Show me the diff and let me review before I apply anything.
