Zen strip mode: zen tab retention · case 01

The tab workspace reports an incorrect zen tab retention.

Verified by executionVariant 1 · 8 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The zen tab retention decision uses [] if x['zen'] and x['hide_tabs'] else x['tabs'] instead of x['tabs'].

VERIFIED REPAIR

Use the stipulated workspace rule: x['tabs'].

Unsuccessful approach: The partial repair [x['selected']] still violates a workspace boundary or normal case.

Case contract

Zen mode may hide tab strips without closing views. Exiting restores prior strip visibility, preserves selected documents and reclaims only the configured strip height.

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.
