Table clipboard paste mapping: start row identity · case 02

The table start row identity result violates the stipulated table clipboard paste mapping contract.

Member previewVariant 2 · 3 implementations · 9 checks per implementation

Case contract

Paste maps source offsets to visible table coordinates starting at a stable cell; source raggedness is retained, table edges clip, readonly holes consume coordinates but not patch capacity, raw values remain unchanged, and truncation means an additional writable patch was omitted.

Why this case matters

An offline table UI model isolates table clipboard paste mapping, including adversarial row/column relationships.

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
offset rectangular paste	`{"patches": [["r0", "b", 2], ["r0", "c", 2], ["r1", "b", 3], ["r1", "c", 4]], "rejected": [], "truncated": false}`	`{"patches": [["r1", "b", 2], ["r1", "c", 2], ["r2", "b", 3], ["r2", "c", 4]], "rejected": [], "truncated": false}`	Failed
