dsh-diff-view

Across the DSH ecosystem, every client plugin that needs to render a before/after text diff used to ship its own engine, its own line-number math, and its own stylesheet, which meant line numbers drifting after context collapse, inconsistent styling, and duplicated code scattered everywhere. dsh-diff-view consolidates all of that into a single zero-dependency shared service: install the adf-* stylesheet once, and every consuming plugin renders diffs through the diffView client service without writing a line of CSS or diff logic of its own. The engine performs line-level LCS with intra-line word highlights, computes true line numbers before any context collapse so they stay accurate across ellipsis bands, and lets each component instance toggle between split and unified views independently. There is no persistence, no approval coupling, and no standalone UI; the host side is a stub. Plugins inject the service and render immediately. It is built for DSH plugin authors who need reliable, visually consistent diff rendering without reinventing the wheel.
