Context

The SadConsole terminal Writer uses a deferred-wrap model (PendingWrap flag) per ECMA-48 §7.1. When the cursor reaches the right margin, the wrap is deferred until the next printable character. Cursor-movement handlers must decide whether to just clear the flag (most handlers) or resolve the wrap first (advance to next line, col 0).

Pattern: Forward-Movement PendingWrap Resolution

Any handler that moves the cursor forward along the line (increasing column) must resolve PendingWrap, not just clear it. Without resolution, forward movement from the right margin is clamped to width-1 → a no-op.

Detection Rule

A handler is AT RISK if:

It moves the cursor forward (increasing column index)
The movement is relative to the current position
The target is clamped at width - 1
