Expo Smoke Test

This skill requires project-knowledge. Before doing any work, confirm it is installed. When it is missing, stop and report it with its install command, npx skills@latest add toy-crane/skills --skill project-knowledge, using the project's package manager runner where it pins one.

Prove two things on each platform: the current change works, and the app's core loop still works. Static inspection, type checks, unit tests, and a successful bundle support the result but do not replace device verification.

Establish the run

Inspect the request, the current diff, the Expo config, and the package manifest to identify the flow the change affects and its observable result.
