Tab decoration measurement: dirty footprint · case 01

The tab workspace reports an incorrect dirty footprint.

Verified by executionVariant 1 · 6 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The dirty footprint decision uses 0 instead of x['dirty_width']+x['gap'] if x['dirty'] else 0.

VERIFIED REPAIR

Use the stipulated workspace rule: x['dirty_width']+x['gap'] if x['dirty'] else 0.

Unsuccessful approach: The partial repair x['dirty_width'] if x['dirty'] else 0 still violates a workspace boundary or normal case.

Case contract

Tab label layout reserves distinct icon, dirty marker, close button and padding footprints before truncating the title; absent decorations consume no width.

Why this case matters

Offline tab/panel workspace behavior; no browser or desktop framework is emulated.

Verification & scope

Finite stipulated workspace snapshots only. Independent result fields describe observable obligations, not a full UI runtime. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
