Tab resource sharing: released document handles · case 01

The tab workspace reports an incorrect released document handles.

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

ROOT CAUSE

The released document handles decision uses x['document_handles'][x['views'][x['closing']]] instead of x['document_handles'][x['views'][x['closing']]] if not any(v!=x['closing'] and d==x['views'][x['closing']] for v,d in x['views'].items()) else 0.

THE FAILURE

The released document handles decision uses x['document_handles'][x['views'][x['closing']]] instead of x['document_handles'][x['views'][x['closing']]] if not any(v!=x['closing'] and d==x['views'][x['closing']] for v,d in x['views'].items()) else 0.

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.

HELD IN THE MEMBER ARCHIVE

The verified repair and its recorded checks are member-only.

This mechanism has 6 recorded checks per implementation. The open-access tier publishes the failure and the unsuccessful fix; the repaired source that passes every check, and the observations that prove it, are available to members.

Every case sharing this mechanism uses the same contract and the same repair, so this one record is held back for all of them.

Member access is invitation-based. Sign in with your invited account to inspect the repair.

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.
