Visual
What visually changed on the routes the PR touched?
What it asks
Captures snapshots of every changed route during the test run, diffs against the baseline (the merge target's most recent snapshot), and scores `100 - maxDiffPercentage`. Pure soft signal in v1 — no hard rules — because pixel-perfect compares produce too many false positives to gate merges deterministically.
Hard rules
- •analyzer_error — the visual capture itself crashed; the umbrella escalates the same way it does for any signal that fails to produce a verdict.
Soft signal
Visual score 0–100. Composite weight in izri/quality: 0.15. A chorus of small visual changes plus a small scope drift can still tip the composite below threshold.
When it fires
On every PR run for the routes returned by the project's `changedRoutes` resolver. Premium tier — the analyzer lives in `packages/premium/visual-testing/` under a proprietary license.
