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.

The first device run of the published APK, and the first runtime
evidence any of the Android work has ever had -- A4 shipped entirely
reasoned from source.

It confirms A4 whole: playback survives the screen locking, and the
transport notification appears with cover art, which settles four
open questions at once (the service starts, the permission was granted
and the notification is visible, the lock screen picks up the session,
and art decoded from a MANAGE_EXTERNAL_STORAGE path by a service is
readable -- the one nobody could argue from documentation).

It also found the two faults fixed in the preceding commits, and the
lesson worth keeping is why *those two*: both are things the platform
adds rather than things the app draws. So the skill's Android tier now
says to ask a device about system bars, the back gesture, focus and
audio interruptions, permissions and the keyboard -- and not about
layout, which the other five tiers already cover.

Section A of plan 016 is closed and B1 is decided, so the three tenses
move together: CLAUDE.md for what mediacontrols now is, the skill for
what to run, NOTES.md for what was measured and when.

The entry worth reading is the one that disproves a claim written here
earlier in the same session. Dropping x86_64 was expected to make
make android-install fail with INSTALL_FAILED_NO_MATCHING_ABIS.
Measured, it installs and launches: Google's google_apis x86_64 images
carry arm64 translation (abilist = x86_64,arm64-v8a), so the loader
maps lib/arm64/libwails.so and runs it. It dies before any of our code
with SIGILL, and the disassembly names the reason exactly --
`mrs x0, ID_AA64ISAR0_EL1`, Go's internal/cpu reading the arm64 feature
register at runtime init, which the translator does not implement. So
no Go binary starts under it, and that is not a property of this app.

Which closes the last plausible shortcut. There are now three distinct
ways this app fails on an x86_64 Android -- seccomp on the x86_64
build, an unimplemented system register on the translated arm64 one,
and a real device still unverified -- and none of them is a bug in it.
A phone remains the only verification path.

Plan 016 also carries the B2 scope, now decided rather than
recommended: option 1's data model with option 2's surface. The phone
gets home, library browse, now-playing-as-a-view, the queue, search and
playlists; it does not get autotag, downloads, Explore or the 93-control
Settings page, and each of those has a reason written beside it. One
rule for the work: no view forks, because a phone template that copies
a view's is two templates to fix every bug in.

logan f7dc76c955 docs(android): an arm64 image will not run on an x86_64 host

Build & publish the Android APK / apk (push) Failing after 50s
Emulator 37 refuses cross-architecture emulation outright -- "Avd's CPU
Architecture 'arm64' is not supported by the QEMU2 emulator on x86_64
host" -- and there is no flag for it. Google dropped it.

That matters because the previous commit's finding points at arm64 as
the ABI that works, so the obvious next move is to boot an arm64 AVD,
and the obvious next move costs a 3.8 GB download before it fails.
Written down so the next session does not spend it.

The consequence is stated rather than hidden: the claim that arm64
avoids the seccomp trap rests on reading modernc's two code paths, not
on having run it. Verifying it needs an arm64 host, a physical device
or adb connect.

logan ed975019dc 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.

logan 68468e5378 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.
