feat(dev): ask the phone instead of looking at it
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. |

fix(dev): the Android harness did not parse, and then chose any device
Two bugs, and the first had made every make android-* target dead since the commit that introduced it. **The script did not parse at all.** A case pattern read `*signatures do not match*)`, and `do` is a reserved word: bash rejects the *whole file*, so android-emulator, android-install, android-smoke and android-logs all died with "line 190: syntax error near unexpected token `do'" -- a message that points at a line nobody had reason to suspect, in a file that had been working. Quoting the inner words fixes it. A shell script only ever run by hand can carry a syntax error indefinitely; nothing in the pre-commit hooks runs bash -n. **A bare adb addresses whatever is attached.** With a second emulator present -- another project's, or this one's own corpse left `offline` by a previous run -- every adb call fails with "more than one device", and cmd_install reported that as "no device - run 'make android-emulator' first" *directly after* that had printed "waiting for boot ok". Which is the harness's own house rule broken: a failure that names the wrong cause is worse than one that names none. pick_device resolves ANDROID_SERIAL from ro.boot.qemu.avd_name before any device command. The AVD name is the identity because serials are assigned in boot order and change between runs; a caller's own ANDROID_SERIAL wins, and a single device that is not ours is taken as the target, since that is a phone and a phone is what this tier actually wants. Verified with both emulators running. |

fix(dev): the smoke target died silently on a genuinely dead app
Two harness bugs and the finding that exposed them. **`pidof` exits 1 when it finds nothing**, and under `set -e` a failing command substitution killed the script before it could print anything -- rc=1, no output. That was invisible for as long as the app crash-*looped*, because there is always some pid in that state. It appeared the moment the app died for good and ActivityManager stopped respawning it, which is precisely the run you most want output from. **And an install failure said nothing useful.** Both ways it fails are about identity rather than the build: INSTALL_FAILED_VERSION_DOWNGRADE when a bare `make android` (versionCode 1) meets something a versioned build left behind, and a signature mismatch when a debug-signed local build meets a release-signed one. Both were hit in one session, and both are fixed by uninstalling. The target says so now instead of leaving someone to read the constant name. The finding: with the startup bug fixed the app reaches the database and takes SIGSYS on the x86_64 emulator, because modernc.org/libc's Xlstat64 issues a raw lstat syscall on linux/amd64 and Android's seccomp filter forbids it -- bionic never issues it. arm64 has no lstat syscall at all, so ccgo_linux_arm64.go routes Xlstat through fstatat and is structurally unaffected; Go's own syscall package already used fstatat on both. So the default emulator cannot verify this app, and the skill says so rather than letting the next session read a tombstone as a regression. |

feat(dev): an Android failure looks exactly like a success
The APK installs and launches. It also dies six milliseconds later, and finding that out cost a cycle for three reasons that have nothing to do with the bug itself: **Go's stdout does not reach logcat.** An Android app's fd 1 and 2 go to /dev/null, so every slog line -- including the one naming the error the app is about to exit on -- is discarded. `setprop log.redirect-stdio true` does not help: that redirects the Java runtime's System.out, and our code is a c-shared native library. **os.Exit leaves no evidence.** No panic, no AndroidRuntime stack, nothing in /data/tombstones, nothing in `logcat -b crash` or dropbox. All three places anyone would look are empty, and the one signal that is present -- "Zygote: exited due to signal 9" -- reads as "the system killed it" and sends you after the low-memory killer. **ActivityManager restarts it faster than you can observe.** pidof always answers and `am start` always reports Status: ok, so a crash-looping app looks alive. "Did it start" is the wrong question; `make android-smoke` asks whether it is the *same pid* N seconds later, and prints the filtered logcat plus how to read it when it is not. The tell, once known: "I/WailsBridge: Wails bridge initialized" followed immediately by a new pid doing the same thing. scripts/android-emulator.sh follows dev-headless.sh's shape -- background start, saved-PID stop, filtered log tail, never pkill -f. Two scaffold tasks are deliberately not wrapped: `android:logs` greps logcat for (Wails|yellowjacket), which catches the WailsBridge tag but misses the app's own process tag (app.yellowjacket is lowercase) and misses ActivityManager's "has died" line, which is the one that says it crashed; and `ensure-emulator` boots whatever `-list-avds | tail -1` returns, with no pidfile and no boot wait, so it cannot be sequenced. One environment note that is not obvious on Arch: Gradle needs a platform and /opt/android-sdk has none, so ANDROID_SDK defaults to ~/Android/Sdk while ANDROID_NDK points at /opt/android-ndk. Two SDKs, one for each half of the build. |
