NO-ISSUE: retry cosign sign in push_and_sign_chart

[adriengentil]

Summary

• Wraps cosign sign in push_and_sign_chart with retry_command (60s timeout, 10s interval), matching the existing helm push retry pattern
• Transient OIDC/Fulcio/registry errors can cause cosign sign to fail after a successful helm push; retrying recovers without failing the whole nightly run

Test plan

• Nightly chart publish job succeeds when cosign encounters a transient error on the first attempt

🤖 Generated with Claude Code

Summary

• The nightly chart-publishing script now retries cosign sign with retry_command 60 10.
• If signing still fails, the existing error handling reports the failure and returns its exit status.
• This affects CI chart publishing. It does not change the API surface, controllers, database, authentication configuration, tests, or documentation.
• No backward-compatibility impact is indicated.

Tests

The supplied test plan is unchecked. No test execution result was provided.

Risk classification

No risk label or labeling criteria were supplied. The applied label and its specific criteria cannot be established from the available evidence.

A transient partial signing failure can cause nightly chart publishing to fail permanently despite retries. Make signing retries idempotent before merging.
