## What changed
- Honor `RuntimeAgentInstances` and the configured runtime auth mode for Analytics plan discovery and report requests to OpenAI endpoints.
- Share installation ID resolution and Codex runtime registration setup through `codex-runtime-agent-instance`.
- Preserve typed runtime authentication errors so expired credentials retain the “Sign in again to load Analytics” guidance.
## Testing
Add coverage for both runtime auth modes across regional and staging endpoints, fresh assertions for each request, sign-in guidance after bootstrap failure, redirect rejection, and invalid organization/project selectors.
