Tab resource sharing: released view listeners · case 01

The tab workspace reports an incorrect released view listeners.

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

ROOT CAUSE

The released view listeners decision uses sum(x['subscriptions'].values()) instead of x['subscriptions'][x['closing']].

VERIFIED REPAIR

Use the stipulated workspace rule: x['subscriptions'][x['closing']].

Unsuccessful approach: The partial repair 0 still violates a workspace boundary or normal case.

Case contract

Several tab views may share one document. Closing one view releases only its view resources and closes document resources only when no other view references that document.

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.
