Deleted open document: missing path tooltip · case 04

The tab workspace reports an incorrect missing path tooltip.

Member previewVariant 4 · 3 implementations · 6 checks per implementation

Case contract

External deletion leaves dirty tab buffers recoverable, marks missing backing files, permits Save As, and closes clean tabs only under the explicit close-clean policy.

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	`[["a", "b"], ["b"], ["a"], {"b": "b.txt"}, ["b", "c", "background0", "background1", "background2"], {"a": "/project/a.txt", "b": "/project/b.txt"}]`	`[["a", "b"], ["b"], ["a"], {"b": "b.txt"}, ["b", "c", "background0", "background1", "background2"], {"a": "/project/a.txt (missing)", "b": "/project/b.txt (missing)"}]`	Failed
