Table fill handle repetition: negative coordinate · case 04

The table negative coordinate result violates the stipulated table fill handle repetition contract.

Member previewVariant 4 · 3 implementations · 6 checks per implementation

Case contract

Fill repeats the source rectangle modulo its original row/column origin, excludes the source itself, respects axis constraints and individual readonly cells, clips targets to table bounds, and emits patches in row-major order.

Why this case matters

An offline table UI model isolates table fill handle repetition, including adversarial row/column relationships.

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
negative viewport	`[["r1", "b", 1], ["r1", "a", 1], ["r1", "b", 1], ["r0", "b", 1], ["r0", "b", 1], ["r1", "b", 1], ["r1", "a", 1], ["r1", "b", 1]]`	`[["r0", "b", 1], ["r1", "a", 1], ["r1", "b", 1]]`	Failed
