Port the reader screen's chrome to a Robolectric JVM Compose test (umbrella
ReaderScreenJvmTest drives the real ReaderViewModel over a mocked
MailRepository/SettingsRepository via the v2 createComposeRule() — no emulator —
covering the top bar, star/delete/reply/reply-all/forward actions, the
attachment accordion + downloaded indicator, the attachment download-failure
snackbar, and the loading/plain-text/empty/error/remote-images-banner branches.
WebView caveat: the HTML body renders through HtmlBody, a hardened WebView that
Robolectric can only present as a non-rendering shadow, so the banner branch is
driven via an HTML message with a blank body (no HtmlBody call) and no
WebView-rendered HTML is asserted. HtmlBody.kt stays in scope, covered by its
existing HtmlBodyTest/InlineImageResolverTest. The instrumented ReaderScreenTest
stays as the on-device E2E. ReaderScreenKt lands at 94.3% line coverage; the
bundle rises to 82.7%, above the unchanged 0.79 floor.

Implements issue #409: a serial Mergify merge queue that supersedes the
hand-rolled poor-man's queue (autoupdate.yml + ci-trigger.yml +
traffic-control.yml, all already disabled_manually).
- queue_rules "default": batch_size 1 (serial, no batching), merge_method
merge (merge commits, never squash/rebase), merge_conditions gate on
check-success = "CI passed" + -draft + -conflict + label != broken.
- merge_queue.max_parallel_checks 1 (true serial; unambiguously
require-up-to-date-compatible).
- priority_rules map P0..P9 labels (P0 = 10000 highest .. P9 = 1000).
- pull_request_rules queue action triggers auto-queueing (queue_conditions
alone do NOT auto-queue per Mergify lifecycle docs).
require-up-to-date STAYS ON (Phase 1 is the only trilemma combo that keeps
the checkbox literally enabled AND preserves merge commits). No batching
(that is Phase 2 / #410). Single required gate stays "CI passed".
Validated: YAML parses and conforms to Mergify's published JSON schema
(negative-control confirmed). Merging this activates Mergify, so NO
auto-merge — must be reviewed first.

Investigate Mergify (free-for-OSS merge queue + batching + speculative checks)
as the right-way replacement for the hand-rolled traffic-controller
(autoupdate.yml + ci-trigger.yml + mothballed traffic-control.yml) and the
manual serial-bump grind, now that GitHub's native merge queue is org-only and
unavailable to a user account.
Proposal only — NO live .mergify.yml, nothing activates:
- docs/ci/mergify-integration-spec.md: how the queue coexists with the single
`CI passed` gate; the require-up-to-date x merge-commits x batching trilemma
and its resolution (Phase 1 serial keeps the rule literally; Phase 2 merge-batch
moves the up-to-date GUARANTEE into the queue); P0-P9 -> priority_rules mapping;
what it replaces; interaction with path-filter/sharding/wedge-diag; risks;
phased adopt recommendation.
- docs/ci/mergify.yml.proposed: annotated, NOT-active proposed config.

Convert the VM-driven mail list screens (DraftsScreen, OutboxScreen,
ProblemReportsScreen) to Robolectric JVM Compose tests in the `test`
source set, driving each real ViewModel over a mocked MailRepository /
ReportStore + DiagnosticsCollector via the v2 createComposeRule() — no
emulator. Each test covers the empty/populated render states, item
rendering (subject/recipient/body, queued-vs-failed status, crash/manual
kind labels), and the interactions (open, delete, cancel, retry, create).
Drop the three now-JVM-covered globs from jacocoNonJvmTestableSurface so
the screens count toward the JaCoCo denominator; measured coverage is
DraftsScreen 100%, OutboxScreen 100%, ProblemReportsScreen 97%, and the
bundle line ratio rises to ~82.7% (floor 0.79 unchanged). The instrumented
androidTest E2Es (DraftsScreenTest / OutboxScreenTest /
ProblemReportsScreenTest) stay as the on-device tests.
Part of the Robolectric Compose umbrella (#373); mirrors the #375/#376
pattern (AddAnotherAccountScreenJvmTest, format-control JVM tests).

Add a cheap `changes` job (dorny/paths-filter v4, pinned SHA) that sets
e2e_needed=false only when EVERY changed file is in a safe allow-list
(app/src/test/**, **/*.md, docs/**, scripts/**, .claude/**); anything
else -- or any non-pull_request event -- defaults to true (conservative,
"err toward running E2E").
Gate `e2e` and `e2e-preview` on needs.changes.outputs.e2e_needed so the
whole matrix runs or skips together, and rewrite the `ci-passed` gate:
it now BLOCKS on changes!=success, any of traffic-control-tests /
static-analysis / debug-build / unit-tests !=success, or e2e/e2e-preview
==failure|cancelled -- while TOLERATING an intentional e2e/e2e-preview
'skipped'. So test-only/docs PRs go green on the fast gate, a real E2E
failure/cancel still blocks, and a broken filter (changes!=success)
still blocks. Branch protection ("CI passed") context is unchanged.

Add Robolectric JVM Compose tests (umbrella #373, batch 3/9) for the
account-setup screens and drop them from `jacocoNonJvmTestableSurface` so
their render/interaction code counts toward the JVM-testable coverage surface:
- AccountPickerScreen (98.9% line)
- AppPasswordSetupScreen (98.7% line)
- ManualSetupScreen (98.5% line)
Each test drives the real screen via the v2 `createComposeRule()` under
RobolectricTestRunner with a mocked ViewModel (their own logic stays covered by
the ViewModel unit tests), a RESUMED LifecycleOwner for
`collectAsStateWithLifecycle`, a no-op ActivityResultRegistry for the Outlook
launcher, and a recording UriHandler for the app-password help links — covering
render, per-provider chrome, field/submit wiring, and the enabled/busy/error/
done branches. The instrumented androidTest E2Es stay as the on-device coverage.
The JaCoCo floor (0.79) is unchanged — the re-ratchet is the final #373 step.

Add Robolectric JVM Compose tests (umbrella #373, batch 2/9) for the
stateless onboarding + lock screens, and drop each from
jacocoNonJvmTestableSurface so its render/interaction code now counts as
JVM-testable surface:
- LockScreen: locked title/body, optional error, unlock callback.
- WelcomeContent + OnboardingWelcomeScreen: render + add-account; the
wrapper's NotificationPermissionEffect launcher is wired to a no-op
ActivityResultRegistry so no system dialog is surfaced on the JVM.
- LicenseScreen: real bundled GPL text renders, Agree gated on
scroll-to-end, Decline.
- ContactsAccessContent (skip/grant/request/rationale) plus the
ContactsAccessScreen wrapper, driven by a mocked OnboardingViewModel.
- BatteryOptimizationScreen: offered vs. done states; Take me there marks
the prompt handled and resolves the settings intent; Not now finishes.
Contacts/Battery use a tall @Config qualifier so their centered,
non-scrolling columns fit without the lower controls clipping. The
instrumented androidTest tests are kept (and remain the coverage for the
system back press, which the JVM compose rule cannot drive). JaCoCo floor
unchanged at 0.79 (the re-ratchet is the final #373 step).

The on-device perf harness cannot force a genuinely uncached body fetch: proactive
backfill (#12) and post-sync body prefetch (#88/#89) warm the cache before a test can
open a message. Add a debug-only, adb-reachable hook to pause proactive fetch so a real
uncached open can be measured.
Components:
- DebugFetchGate (src/main): thread-safe in-memory holder of paused FetchScopes
(BACKFILL, PREFETCH; `all` alias). Defaults to not-paused; HEADER_SYNC and on-demand
OPEN are never gateable.
- FetchGateReceiver (src/debug only): BroadcastReceiver registered in the debug manifest,
driven by `adb shell am broadcast -a org.libremail.debug.FETCH_GATE -n .../FetchGateReceiver
--es action <pause|resume|query> --es scope <backfill,prefetch|all>`. Returns the state as
ordered-broadcast result data (paused=[...]) for a synchronous read-back.
Enforcement (each read guarded by BuildConfig.DEBUG so R8 strips it from release):
- BackfillWorker.doWork() entry -> skip-and-reschedule when BACKFILL is paused, mirroring
the existing cache-lock deferral (covers periodic + backfillNow()).
- MailSyncer/MailBackfiller.prefetchIfEnabled -> early-return when PREFETCH is paused.
openMessage / fetchBodyMarkingSeen / fetchAttachment are deliberately NOT gated.
Debug-only: receiver + <receiver> live wholly in src/debug; every gate read in main is
behind BuildConfig.DEBUG. Verified on assembleRelease that R8 strips DebugFetchGate /
FetchScope / FetchGateReceiver and the log strings from the release APK, and the merged
release manifest has no FETCH_GATE receiver.
PII-free AppLog breadcrumbs on pause/resume/query and on each gate-triggered defer/skip
(scope names only).
Tests: DebugFetchGateTest, BackfillWorkerTest / MailSyncerTest / MailBackfillerTest
enforcement cases, and FetchGateReceiverInstrumentedTest (ordered-broadcast -> gate ->
read-back; gated worker defers while an un-gated path runs).

Port the instrumented ColorSwatchRow / FontPicker / FontSizePicker /
ParagraphAlignmentControl tests to Robolectric JVM Compose tests (v2
createComposeRule, @GraphicsMode NATIVE, @Config sdk=36) in the `test`
source set, and drop their four globs from `jacocoNonJvmTestableSurface`
so they count toward the JVM coverage metric. The instrumented tests stay.
Also fix a latent gap in the #375 infra: the JaCoCo agent skips classes
with no code-source location, which is exactly how Robolectric loads the
classes-under-test through its sandbox classloader — so Robolectric-only
Compose coverage recorded as zero (the PoC AddAnotherAccountScreen
included). `isIncludeNoLocationClasses = true` on the Test tasks makes
that coverage register; scoped bundle line coverage rises ~0.80 -> ~0.82.
Floor left at 0.79 (#386 re-ratchets).

The dominant merge-blocking flake was the "Set up Android SDK" step
(android-actions/setup-android v4.0.1) dying BEFORE the emulator starts:
Wrong version in preinstalled sdkmanager
Warning: ... preparing SDK package Android Emulator: Error reading Zip
content from a SeekableByteChannel.
Error: The process '.../sdkmanager' failed with exit code 1
Root cause: the action's default cmdline-tools version (20.0) rarely matches the
runner image's preinstalled one, so it logs "Wrong version in preinstalled
sdkmanager" and re-fetches cmdline-tools with NO checksum; it then runs its
default `sdkmanager tools platform-tools` install. Any of those downloads can be
a corrupt/truncated zip, which sdkmanager turns into an un-retried exit 1. v4.0.1
is the latest release, so this is fixed by configuration + hardening, not a bump.
Harden with verify -> reject -> retry, never trusting sdkmanager's exit code
alone, via a new stdlib-only helper .github/scripts/setup_android_sdk.py:
- bootstrap: download the pinned cmdline-tools zip, verify size + SHA-256
(authoritative pin, cross-checked against Google's published SHA-1), and
install it to $ANDROID_SDK_ROOT/cmdline-tools/20.0 -- the exact path
setup-android probes first, so the action reuses the verified tree and never
does its own unverified "Wrong version" re-download. A mismatch (corrupt OR
wrong version) deletes the bad zip + any half-extracted dir and re-downloads.
- install: sdkmanager --install with retry + backoff; on a corrupt package zip it
purges the partial/corrupt package dir (and sdkmanager's temp dirs) before
retrying, forcing a fresh download instead of a re-read.
- setup-android now runs with packages: "" (no flaky tools/platform-tools
install) and cmdline-tools-version: "14742923" (reuse the verified bootstrap).
- actions/cache restore + success-gated save so only a verified SDK is ever
cached (integrity gates the cache); shrinks the re-download/corruption surface.
Applied to every SDK-setup job (debug-build, unit-tests, static-analysis, e2e
matrix, e2e-preview). Emulator BOOT logic, #372 API-37 sharding, and #388
diagnostics are untouched. Pure-logic helpers are unit-tested
(test_setup_android_sdk.py, run by the traffic-control-tests job).

The API 29-36 `e2e` matrix uploaded only its test report, so an emulator
flake or a red leg (e.g. `E2E (31)` dying on a bare `sdkmanager` exit 1)
left nothing to diagnose. Bring the #334 API-37 diagnostics to the matrix,
inline (no changes to `e2e-preview`, which PR #372 is restructuring):
- Stream `adb logcat -v time` to `$RUNNER_TEMP/logcat-api<level>.txt` at the
top of both the "Run E2E tests" and retry reactivecircus steps (emulator is
booted there); backgrounded so gradle stays the exit-status-bearing command.
- New `if: failure()` step dumps device + runner state (adb devices, logcat
tail, emulator -accel-check, /dev/kvm, free -h, df -h) to the step log and a
diagnostics file; every probe guarded with `|| true`.
- New `if: always()` upload-artifact (same pinned v7 SHA) `e2e-diagnostics-api<level>`
carries the logcat + diagnostics files, `if-no-files-found: warn`.
- Make "Install SDK platform and build-tools" diagnosable: bounded 3x retry with
backoff for a transient sdkmanager failure, and print `--list_installed` on a
hard failure instead of a bare exit 1.
Keeps reactivecircus/android-emulator-runner and the existing boot-race retry.
Additive/diagnostic only; no boot-affecting flags change.

Robolectric resolved its android-all-instrumented runtime jar lazily at test
time via its own MavenDependencyResolver/MavenArtifactFetcher, and that
download is unreliable on CI runners: AddAnotherAccountScreenJvmTest failed
with `AssertionError at MavenArtifactFetcher ... IOException` ("Failed to
fetch maven artifact"), though it passed locally where ~/.m2 was warm.
Resolve the jar through Gradle instead (reliable, cached, persisted by the CI
Gradle cache) and hand it to Robolectric in offline mode so it never hits the
network at test time:
- Pin org.robolectric:android-all-instrumented:16-robolectric-13921718-i7
(exactly what Robolectric 4.16.1 DefaultSdkProvider maps @Config(sdk=36) to)
in the version catalog.
- Add it to a dedicated resolvable configuration (NOT testImplementation/
testRuntimeOnly, which would flatten the ~200MB instrumented framework onto
the JVM test classpath and collide with the stub android.jar).
- syncRobolectricAndroidAll stages the jar under its Maven filename, and
robolectric.offline + robolectric.dependency.dir point Robolectric's
LocalDependencyResolver at it.

Enables unit-testing Jetpack Compose UI on the JVM via Robolectric, so
render-only screens can leave the jacocoNonJvmTestableSurface exclusion
list and be counted by JaCoCo without an emulator.
- add Robolectric 4.16.1 (test scope) + Compose ui-test-junit4/-manifest
- testOptions.unitTests.isIncludeAndroidResources = true so resources
(strings, Material3 theme) resolve on the JVM
- src/test/resources/robolectric.properties pins sdk=36 (targetSdk 37 is
a preview level Robolectric 4.16 has no sandbox for)
- PoC: AddAnotherAccountScreenJvmTest drives the screen with the v2
createComposeRule under RobolectricTestRunner (3 tests, green on the JVM)
- drop AddAnotherAccountScreen from jacocoNonJvmTestableSurface (now
JVM-covered); floor stays 0.79 — re-ratchet deferred to end of #373

The spike commits already implemented the N=2 shard matrix (numShards/
shardIndex via -Pandroid.testInstrumentationRunnerArguments.*), per-shard
test-retry parity, adb start-server before the boot loop, and shard-suffixed
artifact names. This drops the SPIKE / DRAFT "do not merge as-is" framing from
the ci.yml comments and reframes docs/perf/api37-e2e-sharding-spike.md from a
feasibility spike into the adopted design, so the change is mergeable as-is.
Also fixes the doc's section 3a example, which showed 1-based shardIndex values
[1, 2]; shardIndex is 0-based (0..numShards-1) and the implementation correctly
uses matrix.shard: [0, 1] -- [1, 2] would run an empty bucket and silently drop
half the suite.
Fan-in unchanged and verified: ci-passed still lists e2e-preview once; GHA
matrix aggregation makes its result `failure` if either shard fails, so both
shards must pass for the gate to go green. Branch protection requires the
"CI passed" context (not the per-leg "E2E (API 37 preview) (N)" check names),
so no branch-protection change is needed.

SignaturesScreenTest built a real SignaturesViewModel by hand but tore down
with a bare `db.close()` that never cancelled viewModelScope. The ViewModel's
`signatures` StateFlow is a Room InvalidationTracker Flow kept alive by
stateIn(WhileSubscribed(5_000)), so the collector could stay live up to 5s
after the UI detached — a re-query then landed on the just-closed in-memory DB
and threw SQLITE_MISUSE ("connection is closed"). Timing-dependent, hence the
intermittent API-37 CI failure in tappingRadioOnNonDefault_makesItTheDefault.
Fix: hold the ViewModel in an androidx.lifecycle.ViewModelStore and, in @After,
call store.clear() (→ ViewModel.onCleared() → cancels viewModelScope) BEFORE
db.close(), so the collector is gone before the DB closes. Behaviour and
assertions are unchanged; the fix removes the race by construction.
Audited the androidTest tree for the same hazard and fixed two siblings the
same way:
- AccountSettingsScreenTest: had the same live-Room-Flow-vs-close race,
previously worked around by never closing the in-memory DB at all; now
clears the ViewModel then closes the DB.
- ComposeScreenTest: ComposeViewModel's init launches a viewModelScope
coroutine that reads the real accountSettings/signature Room repos; clear
the store before db.close() to avoid the same in-flight-read-vs-close race.
Verified locally: connectedDebugAndroidTest green for all three classes
(12/12) on a cold-booted emulator, plus the JVM fast gate (assembleDebug,
testDebugUnitTest, jacocoTestCoverageVerification, compileDebugAndroidTestKotlin,
lintDebug, ktlintCheck, detekt).
