📝 Walkthrough

Walkthrough

The Lab page now displays a scatter chart of hourly activity, grouped by score classification and text verdict. The chart calculates text-verdict strength from confidence and probability, and shows classification, PR, repository, score, strength, and verdict details. When repository and PR details are present, clicking a datapoint opens the GitHub PR in a new tab. The change also adds optional text-verdict fields to ActivityItem, updates vue-data-ui, and adds its scatter module to Vite’s optimized dependencies.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to ee325

Some chart points may show misleading strength or PR details. These are bounded display issues, so the change is mergeable with owner awareness and follow-up.

Security Architecture Review

Security architecture risk: 🔵 Low · up to ee325

The change remains a read-only visualization of existing activity data. Displayed metadata uses text interpolation, and PR navigation retains a fixed GitHub origin with opener isolation. No introduced security issue was established, but upstream data guarantees, deployment access controls, and dependency internals were not verified end to end.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The new presentation makes repository, PR, score, and verdict metadata visible in chart tooltips, but consumes the same hourly activity endpoint available before this PR. The inspected change does not establish a new server-side data-access boundary.

Trust Boundaries and Controls

• observed — Activity metadata reaches the custom tooltip through Vue text interpolation rather than raw HTML. Datapoint navigation requires repository and PR values, constructs a URL with a fixed https://github.com/ prefix, and opens it with noopener,noreferrer.

Review comments at @app/components/Chart/PrTextVerdictScatter.vue:
- Around line 20-21: Update the record filter in PrTextVerdictScatter so it adds
a result to source only when text_confidence and text_probability are finite
numbers, in addition to the existing property and score checks.
- Line 113: Update the point-name construction in the dataset mapping to show a
clear missing-PR label when item.pr is absent, without filtering out the point.
In the tooltip, provide a missing-PR label instead of a bare hash and show the
click instruction only when the click handler can open the PR link.
