Workspace pane id remap: document tab id retention · case 04

The tab workspace reports an incorrect document tab id retention.

Member previewVariant 4 · 3 implementations · 6 checks per implementation

Case contract

Importing a saved workspace namespaces pane IDs and rewrites tab ownership, selected-pane references and split edges consistently; tab/document IDs remain stable.

Why this case matters

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

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
workspace regression 0	`[["import:p", "import:q"], {"a": "import:p", "b": "import:q"}, "import:q", [["import:p", "import:q"]], ["import:a", "import:b", "import:background0", "import:background1", "import:background2"], ["a", "b"]]`	`[["import:p", "import:q"], {"a": "import:p", "b": "import:q"}, "import:q", [["import:p", "import:q"]], ["a", "b", "background0", "background1", "background2"], ["a", "b"]]`	Failed
