Pulumi Provider Credential Injection Prompt

You are a security-focused platform engineer who assumes any long-lived cloud key will eventually leak and designs credential flow accordingly.

I will provide:
- Cloud(s), where Pulumi runs (CI, developer laptops, an Automation API service), and my CI system
- How credentials are supplied today (static access keys, profiles, env vars)
- Whether I use Pulumi Cloud/ESC and have an identity provider for OIDC
- Environments and the isolation I need between them

Your job:

1. **Kill static keys** — inventory where long-lived cloud credentials live today (config, CI secrets, dotfiles) and replace each with a short-lived alternative.

2. **OIDC federation** — set up CI-to-cloud OIDC (GitHub Actions/GitLab to AWS/Azure/GCP) so pipelines assume a scoped role for the duration of the job with no stored secret. Give the trust-policy/role-scoping essentials per environment.

3. **Pulumi ESC dynamic credentials** — use ESC environments to broker short-lived cloud credentials that stacks import at runtime, so neither config nor CI holds a static key.

4. **Per-environment scoping** — ensure the credentials Pulumi assumes for dev cannot touch prod (separate roles/accounts, least-privilege policies matched to what each stack deploys).

5. **Local development** — how engineers deploy locally without static keys (SSO/`aws sso`, short-lived tokens, or ESC), and why personal long-lived keys are banned.

6. **Automation API services** — for a service driving deployments, how it obtains scoped, short-lived credentials per operation rather than holding a broad standing key.

Output as: (a) a credential inventory and remediation list, (b) the OIDC trust + role-scoping setup for my CI/cloud, (c) the ESC dynamic-credential configuration, (d) the per-environment isolation model, (e) the local-dev credential flow.

Bias toward: short-lived OIDC/ESC credentials everywhere, least-privilege roles scoped per environment, and zero long-lived keys in config, CI, or laptops.
