The device tier could only take a screenshot and read what Go chose to log, and a screenshot cannot tell a dropped CSS declaration from a missing asset. This adds the third thing: the page's own answer, from the engine that is really rendering it. `make android-screenshot` grabs the screen, `make android-inspect` forwards the WebView's devtools socket, and `make android-eval EXPR=...` evaluates in the real page. Four details are load-bearing. Only a `debuggable` build opens that socket, so the debug build type takes `applicationIdSuffix ".dev"` and installs *beside* the release app -- the two carry different signing certificates, and Android's only remedy for a changed certificate is an uninstall, which takes the user's library with it. Playwright cannot drive a WebView (`connectOverCDP` calls `Browser.setDownloadBehavior`, which it answers "Browser context management is not supported"), so the eval is raw CDP over Node's built-in WebSocket. The socket name carries the pid, so it is resolved per launch rather than written down. And `exec-out`, not `shell`, for the screenshot: a pty translates LF and corrupts the PNG. What it immediately established is why it was worth having. The phone renders in Chrome 113 at 424x439 CSS px -- two years behind every browser the other tiers use, with no Popover API and no relaxed CSS nesting -- so a spec passing at that viewport says nothing about the device, and two conclusions drawn from version numbers alone were wrong. Both are corrected in NOTES.md and the plan.
