Triage CI Failure

Overview

Systematic workflow for triaging and fixing test failures in CI, especially flaky tests that pass locally but fail in CI. Tests that made it to main are usually flaky due to timing, bundling, or environment differences.

CRITICAL RULE: You MUST run the reproduction workflow before proposing any fixes. No exceptions.

When to Use

• CI test fails on main branch after PR was merged
• Test passes locally but fails in CI
• Test failure labeled as "flaky" or intermittent
• E2E or integration test timing out in CI only

MANDATORY First Steps

YOU MUST EXECUTE THESE COMMANDS. Reading code or analyzing logs does NOT count as reproduction.
