Bug Description

Code Review completed successfully and reported finding 4 confirmed issues, but no review comments were posted on the PR. The severity breakdown table shows 0 for every category despite the summary indicating 4 confirmed findings.

Steps to Reproduce

1. Enable Code Review for a repository via admin settings
2. Open a PR (or push to a PR branch, depending on trigger config)
3. Wait for the review to complete
4. Observe the CI check status on the PR

Observed Behavior

The CI check section shows: "Completed in 32m — Code review found 4 potential issues"

Clicking the check details link shows:

• "Found 22 candidates, confirmed 4. See review comments for details."
• Severity table shows all zeros:
• 🔴 Important: 0
• 🟡 Nit: 0
• 🟣 Pre-existing: 0
• No inline comments or summary comments were posted on the PR
• Nothing visible in the Conversation tab or Files changed tab

Expected Behavior

The 4 confirmed findings should appear as inline review comments on the PR, and the severity table should reflect the actual count (summing to 4, not 0).

Additional Context

• Plan: Claude for Teams
• Repository visibility: Private
• PR size: 13 files changed, +431 / -78
• Review completed in 32 minutes

It appears the analysis pipeline successfully identified and confirmed issues, but something failed between the confirmation step and the comment-posting step. The mismatch between the summary ("confirmed 4") and the severity breakdown (all zeros) suggests the categorization/posting step may have errored silently.

What Should Happen?

There should be comments left in the PR, right?
