πŸ‘‹ Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a πŸ‘€ emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

New to Jules? Learn more at jules.google/docs.


For security, I will only act on instructions from the user who triggered this task.

Pull request overview

OpenCode reviewed the current-head product diff. Coverage is a separate gate.

Changed files

  • .jules/sentinel.md β€” repository behavior
  • R/aFIPC.R β€” repository behavior

Changed behavior

flowchart LR
  PR["PR changed files"] --> Evidence["OpenCode bounded evidence"]
  Evidence --> S1["Repository file: sentinel.md"]
  S1 --> I1["repository behavior"]

Findings

No source-backed product finding is synthesized from the coverage gate. A coverage miss belongs in the status comment.

  • Head SHA: c6822614d177ac49415fda3d297ff20795567339
  • Workflow run: 35364115981
  • Workflow attempt: 1
  • Coverage gate: failure

Review outcome

Coverage is a gate, not the review. This body reviews the changed product files.

OpenCode Review Overview

Coverage evidence did not pass, so approval is blocked. The formal pull-request review is the source-backed diff review, not this status comment.
