Summary

This PR configures the CI coverage upload to authenticate with Codecov using OIDC instead of relying on a stored token.

Changes

• Added OIDC permissions to the coverage job: id-token: write (required for Codecov OIDC) and contents: read.
• Enabled use_oidc: true in the codecov/codecov-action step, so Codecov mints a per-run token via OIDC rather than using a stored secret.
• Updated inline documentation to explain the OIDC behavior, including that:
  • Codecov requires a token on protected branches, which OIDC now provides without a stored secret.
  • Fork PRs skip OIDC and upload tokenless, so an upload rejection on fork runs is expected and not a regression.

Purpose

This addresses coverage upload failures on protected branches (where Codecov requires authentication) by using short-lived OIDC-minted credentials, eliminating the need to manage a stored Codecov token secret.

Upload coverage to Codecov via OIDC (LAB-3435)

Summary

This PR updates the CI workflow comments explaining the Codecov coverage upload step, clarifying how OIDC-based authentication behaves across different run contexts.

Changes

• Revised the explanatory comment block above the "Upload coverage" step in .github/workflows/ci.yml to more accurately describe Codecov's token requirements and OIDC behavior:
  • Clarifies that Codecov requires a token on any same-repo branch (not just protected branches), noting that Codecov's own error message refers to it as "protected".
  • Reiterates that use_oidc mints a token per run via the job's id-token: write permission, avoiding the need for a stored secret.
  • Documents that fork PRs never attempt OIDC and upload tokenless, and that a "Token required" error on a same-repo run indicates OIDC failed to mint a token.

Impact

This is a documentation-only change to the CI workflow comments. It improves clarity for maintainers troubleshooting coverage upload issues by accurately describing the expected authentication behavior for same-repo runs versus fork PRs. No functional or workflow behavior is modified.

Summary by CodeRabbit

• Chores
  • Improved automated test coverage reporting with more secure authentication.
  • Coverage uploads remain non-blocking while continuing to report upload failures clearly.
