Walkthrough

The change adds a provisional enhancement document for proxy support in an external OIDC authentication stack. It also adds information-source links to the related context document and Jira issue.

Changes

External OIDC proxy support

Layer / File(s) Summary
Enhancement proposal and references
enhancements/authentication/proxy-support-for-external-oidc-auth-stack.md, enhancements/authentication/proxy-support-for-external-oidc-auth-stack-ctx.md
Adds the enhancement metadata and standard proposal sections. Adds links to the related enhancement document and Jira issue.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟡 Moderate · up to 97372

This change adds an enhancement record rather than runtime behavior, but its proposal and metadata are still incomplete and the related context document has a formatting violation. The design is not yet sufficiently reviewable or ready to merge.

## Summary

The `Summary` section is important for producing high quality
user-focused documentation such as release notes or a development roadmap. It
should be possible to collect this information before implementation begins in
order to avoid requiring implementors to split their attention between writing
release notes and implementing the feature itself.

Your summary should be one paragraph long. More detail
should go into the following sections.

## Motivation

This section is for explicitly listing the motivation, goals and non-goals of
this proposal. Describe why the change is important and the benefits to users.

Replace the copied template with the actual proposal.

The Summary and Motivation sections contain no feature-specific content. The Proposal, Workflow Description, risks, testing, upgrade, and version-skew sections also remain template instructions. Add enough design detail to review the external OIDC proxy behavior, actors, failure modes, and operational boundaries before removing the WIP state.
