Reticle gives coding agents a verdict on the running app

Reticle helps coding agents check what they actually built rather than stopping at the code change. The repository presents a runtime-perception tool for web and desktop apps; reticle compare drives two builds in a browser and reports differences users can see, network calls, and console errors.

Verification happens from outside the app, with no SDK required. The comparator can pit a main build against a pull request preview and, with --base, classify differences as regressions, missed targets, or changes.
