Split the API 37 leg so the part that works can gate
CI has never run the API level this app targets. The reason it did not was never "API 37 is untestable" -- it was that two tests fail on the emulator image, so one row would be permanently red or permanently allow-listed. This splits that row instead of choosing between those two. E2E API 37 gates. It runs 55 of the suite's 57 instrumented tests and must be green. E2E API 37 Media3 hardware transcode runs the other two, reports, and never blocks (continue-on-error). Both are driven off ONE marker, @FailsOnEmulatorApi37: the gating job passes notAnnotation, the advisory job passes annotation. Two lists would drift, and drift is silent in both directions -- a test that ends up in neither job reads as green. Excluding by class was not an option either: Media3EngineTest has four tests and two of them pass here, so notClass would have thrown away real coverage. The advisory job is named for what it runs, not for what we think is wrong. Both its tests drive a full H.264 -> H.265 hardware transcode, which is what distinguishes them from the two Media3EngineTest cases that pass -- those never decode video. The goldfish-decoder theory sits in a comment inside the job, where it can be corrected without renaming a check people have learned to look for; docs/api-37-emulator-crash.md keeps measurement and inference apart. The SystemUI disable moves into .github/scripts/e2e-run.sh behind E2E_DISABLE_SYSTEM_UI, unset everywhere but the two API 37 jobs, so the other four legs run byte-identical commands -- the same shape as E2E_EXTRA_GRADLE_ARGS. It runs BEFORE the streamed logcat starts, deliberately: `adb shell stop` would end that logcat and nothing restarts it, so a disable placed after it would cost the leg its diagnostics for the part of the run that matters. The body is probe v2 from api37-debug.yml -- the version measured 4/4 -- not the older one-round form: three rounds, waits for system_server to actually be gone, verifies against `pm list packages -d`, and requires a 45 s window with zero new aborts. The weaker probe reported success on a run that then started SystemUI eight more times. The caveat is written next to the row rather than left implicit: this leg runs with SystemUI disabled and the framework restarted under it, a device configuration no other leg and no Pixel run uses. Anything that touches system UI must not trust it, and the Pixel check before each release is still the only API 37 run with SystemUI intact. docs/api-37-emulator-crash.md's "So should CI take API 37?" said no on three reasons. Two were claims about CI that had never been measured; the section now carries the eight runs that measured them, and the third reason is what the split answers. docs/local-emulator.md and api37-debug.yml's header carried the same "the matrix stops at 36" claim and are corrected with it. CLAUDE.md is left alone deliberately -- its "CI's matrix therefore stops at API 36" clause is now false, and that correction is parked in the doc's existing "Correction owed to CLAUDE.md" section, where two others are already waiting. Making E2E API 37 an actually-required check is a repository-settings change and must come after this is on main: adding a required context that does not exist on the default branch blocks every PR.

Find out why the emulators segfault, and make them run
CLAUDE.md has said "Emulators segfault on this host -- qemu dies on every AVD" since the E2E matrix landed, and the PR that introduced it called the failure "exit 139 across three AVDs and both GPU backends, environmental". That is accurate about the symptom and wrong about the cause, and the cost of being wrong was the whole instrumented suite being unrunnable here. SwiftShader's Reactor JIT writes generated GLES shader code onto the heap and mprotects it executable. Fedora's SELinux policy denies that -- execheap is not granted to unconfined_t and selinuxuser_execheap is off -- so the mprotect fails and the emulator takes SIGSEGV the moment it calls the routine it just generated. The AVC denial and the core are the same event, one second apart. The predictor is mechanical and held 7 for 7 across every -gpu mode: a run crashes if and only if it dlopens gles_swiftshader/libGLESv2.so. host, angle_indirect and swangle_indirect boot. auto, off, guest and swiftshader_indirect crash -- and auto is the default, which is why the failure looked universal rather than renderer-specific. tools/local-emulator/run-e2e.sh picks a renderer that works and refuses the ones that do not. It reuses .github/scripts/e2e-run.sh rather than forking it, so the local and CI diagnostics cannot drift; the one change there adds an optional E2E_EXTRA_GRADLE_ARGS that is unset in CI, so CI runs byte-identical commands. The API 33-36 sweep has now been run and is written down. All four levels are green on a local emulator and match the physical Pixel 10 Pro XL baseline exactly: 49 tests, 0 failures, 0 errors, 2 skipped, every level. Those counts come from the result XML, not the UTP console counter, which double-counts skips and reported "Finished 51 tests" on all four. No boot log dlopens SwiftShader GLES and the sweep window holds no AVC denial and no qemu core -- which is confirmation of the mode matrix's first row rather than new coverage, since every one of these runs is -gpu host. The table is still seven modes measured once each. Two things the sweep surfaced that the doc now records: pre-build before sweeping, or a fresh checkout spends API 33's 20-minute wrapper budget compiling and wedges before a test runs; and the device pinning is untested by this run, because the Pixel dropped off USB five seconds before it started. Still offered for review rather than applied: the CLAUDE.md correction the doc drafts. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Adapt LibreMail's emulator instrumentation for the E2E matrix
The E2E legs could fail with almost nothing to show for it. The previous handler
was a single line of semicolons printing meminfo and 60 lines of crash logcat,
and it only ran when gradle RETURNED non-zero -- a hang left nothing at all, and
`adb logcat -d` at the end only holds whatever survived in the ring buffer, which
a chatty run evicts.
The two failure shapes want different evidence, so they are handled separately:
FAILED -- gradle returned non-zero. The test reports already say which test and
why, so this captures the surrounding state: guest memory and
storage, whether the app even installed, native crashes, and the
runner's own kvm/memory/disk.
WEDGED -- gradle never returned and the wrapper timeout killed it. There are no
reports, so the evidence has to come off the live device: which test
was in flight per the TestRunner logcat, whether the binder services
are published, and SIGQUIT thread dumps of both processes. That last
one is the point -- ART writes full stacks to logcat and /data/anr,
which is what separates a deadlocked test from a stuck MediaCodec
from a device that stopped answering. dumpsys media.player is in
there because both engines transcode through MediaCodec, so a hung
conversion shows up in it.
Logcat is now streamed to a file from the start of the step and uploaded whichever
way the leg goes, since the leg worth reading is usually the one that went red once
and green on re-run -- by which time the emulator is gone.
It is a script rather than inline YAML because it has to be. The action splits its
`script` input on newlines and runs each line as its own `sh -c`, so functions and
`if` blocks cannot survive there; that constraint is what produced the one-line
handler in the first place. One line calls the script now.
The wrapper timeout is 1200s against measured ~5-minute healthy legs, so it cannot
trip on a slow-but-working run, and sits far enough under the 60-minute cap to
leave room for the capture. It wraps only the foreground gradle client, never the
emulator the action owns, so it cannot hang the leg itself.
Not adopted from LibreMail: the hand-provisioned AVD boot, its SDK-integrity
installer and its focus gate. Those answer failures this repo has not had, and
replacing a boot path that works to fix problems we do not have is how a working
matrix breaks. Every emulator setting here -- ram-size, disk-size, the ABI filter,
swiftshader -- is untouched, along with the reasoning already written next to it.
