๐ Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a ๐ 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 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
Adds a defense-in-depth Content-Security-Policy to the standalone diagnostics HTML report generated by render_diagnostics_report, reducing XSS blast radius if an escaping regression is ever introduced.
Changes:
- Injects a strict CSP
<meta http-equiv="Content-Security-Policy" ...>into the report<head>. - Documents the security learning/prevention guidance in the Sentinel journal.

Pull request overview
OpenCode exhausted the configured model pool without a usable current-head review conclusion. This is not approval evidence, so the PR is blocked until a source-backed review can establish approval sufficiency or identify concrete fixes.
Findings
1. HIGH .jules/sentinel.md:1 - OpenCode could not establish approval sufficiency
- Problem: every configured model path failed to produce a usable current-head control block.
- Root cause: model execution, timeout, export, normalization, or approval-gate validation did not complete after exponential retry across the configured model pool.
- Impact: approving from deterministic check state alone would miss PR-intent mismatches, missing files, edge-case bugs, robustness gaps, UX/DX regressions, security issues, and CodeGraph-backed base/head flow changes.
- Fix: rerun OpenCode after model availability recovers, or update the PR with the missing files, tests, docs, generated artifacts, and verification evidence needed for a source-backed review conclusion.
- Regression test: keep the approval gate posting REQUEST_CHANGES, not APPROVE or check-only failure, when no model produces a valid current-head review.
Summary
- Result: REQUEST_CHANGES
- Reason: coverage-evidence passed and peer GitHub Checks completed without failures, but no model produced a valid review control block.
- Deterministic evidence checked but not used for approval: current-head changed-file evidence (.jules/sentinel.md, python/fast_mlsirm/report.py); coverage-evidence result success; peer checks from statusCheckRollup excluding this OpenCode check.
- Model outcome: model_pool=exhausted; selected_model=none.
- Head SHA:
31a3bbd5899aea7de9f90dac1bdb03b079867265 - Workflow run: 28540444278
- Workflow attempt: 1
No PR approval was posted because model-output failure is not evidence that the PR has no blockers.

HIGH OpenCode could not establish approval sufficiency
- Problem: the model pool exhausted without a valid current-head review control block, so this changed line cannot be approved from deterministic check state alone.
- Impact: PR-intent mismatches, missing files, robustness bugs, UX/DX regressions, and CodeGraph-backed flow changes could be missed.
- Fix: rerun OpenCode after model availability recovers, or add the missing source/test/docs/generated verification evidence needed for a source-backed approval.
- Verification: rerun the OpenCode Review workflow and confirm it emits APPROVE or source-backed REQUEST_CHANGES for this head SHA.
