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 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).

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).

Folds the #370 root-cause finding into the spike. The stable `e2e` matrix
retries its test run once; `e2e-preview` runs connectedDebugAndroidTest exactly
once, so a flaky test self-heals on API 29-36 but wedges the required gate on
API 37 (e.g. #370's SignaturesScreenTest teardown race).
Doc: adds risk item 9 (retry-parity gap + its sharding interaction — per-test
flake is NOT amplified by sharding unlike boot flake, and a per-shard retry
costs only B + T/N; framed mitigation-not-fix) and two §6 recommendations
(retry parity, mirrored into api37_e2e.py; adb start-server before the boot
loop).
PoC (ci.yml): per-shard single test retry (::warning:: on retried-but-passed)
+ adb start-server before the boot loop. The api37_e2e.py retry mirror stays a
documented recommendation (local path needs a real-emulator validation this
spike did not boot). Still DRAFT, not auto-merged.

Feasibility spike for sharding the e2e-preview job (the hand-provisioned
API 37 / google_apis_ps16k 16 KB-page emulator), CI's longest leg
(~16.4-17.6 min). docs/perf/api37-e2e-sharding-spike.md breaks the leg into
fixed overhead B ~8.3 min (setup + boot + Gradle daemon/config/compile/install)
vs parallelizable test execution T ~8.8 min, models B + T/N for N=2/3/4, and
recommends N=2 (~17.1 -> ~12.7 min, ~28% off the critical path) capped by the
API 30 matrix wall (~12.0 min) beyond N=3.
DRAFT PoC (do NOT merge as-is): converts e2e-preview to a strategy.matrix.shard
[0, 1] fan-out passing AndroidJUnitRunner numShards/shardIndex through the
existing -Pandroid.testInstrumentationRunnerArguments.* channel (no GMD, no
orchestrator, no Gradle change). Artifact names gain a shard suffix;
ci-passed still lists e2e-preview once (matrix fan-in keeps the single gate).
Local preflight stays single-emulator. Relates to #258.

CacheEncryptionGate.kt (the gate composable, blank cover, error screen, and ephemeral
report-review screen added for #359) is pure Compose render code, structurally
unreachable from a JVM unit test the same way every other Screen file in
jacocoNonJvmTestableSurface is. Left in scope, it dragged the whole-app line ratio to
0.78, just under the 0.79 no-regression floor.
Excluded it via "**/CacheEncryptionGateKt*" rather than the usual bare
"**/CacheEncryptionGate*" pattern this list otherwise uses, because
CacheEncryptionGateViewModel is named with "CacheEncryptionGate" as a literal
prefix - the bare wildcard would also have swallowed the already JVM-tested,
94%-covered ViewModel and its sealed CacheEncryptionGateState. CacheEncryptionGateViewModel
and CacheEncryptionUnavailableException stay in scope unchanged.
Verified locally: testDebugUnitTest + jacocoTestCoverageVerification now pass, with
the line ratio recovered to about 0.807 (5,044 covered / 6,249 total lines) - the
same 5,044 covered lines as before, just a smaller, honestly-JVM-testable denominator.

Reworks #367. When SQLCipher native library loading fails while the opt-in
encrypted cache is enabled, the app previously degraded to a plaintext cache
(a silent fail-open that defeats the feature). Now it FAILS CLOSED.
DatabaseProvisioner raises a distinct CacheEncryptionUnavailableException
instead of degrading: it does NOT open plaintext, NOT wipe the on-disk
ciphertext, and NOT write the encryptCache setting. The throw is not
memoized, so a later launch re-attempts and recovers automatically if the
library loads.
A new CacheEncryptionGate wraps the app inside AppLockGateHost (so the
passphrase is already unlocked), probes prepareCache() before any DB-backed
screen composes, and on failure shows CacheEncryptionErrorScreen with the
exact message "Error - decryption could not proceed. Native decryption
library load failure." plus a "Report a problem" action. That action
generates an EPHEMERAL PII-free report via the existing DiagnosticsCollector
(never written to ReportStore, since encryption is unavailable in that
moment) for on-screen review and explicit Copy/Save; the copy says so.
The plaintext AccountDatabase tolerates the exception so accounts stay
readable for the error gate and the report. The encryptCache setting is now
written by exactly one caller: the user Settings toggle.
Tests: fail-closed raises the signal with no plaintext open / no wipe / no
setting write / not memoized; the gate VM resolves Ready vs Unavailable and
builds the ephemeral report; an instrumented error-screen UI test and an
AccountDatabase-resilience instrumented test.

Bind the non-exportable AES-256-GCM keys that seal the SQLCipher cache
passphrase to the hardware StrongBox secure element when the device has
one. Applied in the single shared place, AesGcmKeystoreCipher, so it
covers both the master (KeystoreCrypto) and auth-bound (DatabaseKeyCipher)
keys.
Devices without StrongBox throw StrongBoxUnavailableException at
KeyGenerator.generateKey(); a new generate-with-fallback path catches it
and regenerates a TEE-backed key so key creation still succeeds
everywhere. Guarded on API 28+ (minSdk is 29). Framing, seal/unseal, and
the missing-key policies are unchanged; the passphrase is still never
plaintext at rest and never logged.
Adds a JVM regression test for the StrongBox->TEE fallback via the
existing test seams (existingKey / a new generateKey seam).

Add a cross-platform, standard-library-only Python package under
scripts/device-testing/ that replicates LibreMail's on-device performance-test
scenarios and logging capture, codifying the methodology run by hand on
2026-07-05 (Pixel 10 Pro XL).
Modules:
- breadcrumbs.py: a pure, unit-tested parser for the ImapPerf / MailReader /
Reader / MailBackfiller breadcrumbs, plus open-correlation that reproduces the
manual timing-tables.md figures exactly.
- adb.py: a safety-guarded adb wrapper -- an allow-list of adb subcommands and a
deny-list + assertions on shell commands. The only sanctioned app-state
mutation is clearing LibreMail's own cache/ (exact-match); no pm clear /
uninstall / data wipe, and no touching databases/ files/ shared_prefs/
datastore/ can be constructed.
- uidump.py: uiautomator XML parser + screen recognition (mailbox rows with the
cached "Available offline" flag, reader, and the keyguard / foreign-app guards).
- scenarios.py: cold-open, message-open (uncached), back-nav, prefetch A/B
(fetch-policy toggle) and cross-provider, each keyguard-guarded and driven
through the guarded wrapper.
- report.py + perf_harness.py: aggregates, a timing-tables.md renderer mirroring
the manual write-up, and the CLI (timestamped run dir with the raw logcat, a
filtered breadcrumb extract, and the tables). --dry-run prints the exact
command plan without touching device state.
Tests (stdlib unittest, 68 cases) validate the parser, guardrails, UI
recognition and report against the manual run's real captures (fixtures include
a verbatim perf-extract slice and the reader/lockscreen/alarm dumps). Track the
*.log fixture past the gitignore *.log rule via a scoped negation.

Resolve the IdleService.kt conflict as a union of both intents:
- #354 (already on main): foreground-service lifecycle rework —
onStartCommand delegates to the IdleForegroundStarter seam
(START_NOT_STICKY), cap-window skip/degrade.
- #357 Part 2 / #368: reused-connection idle-eviction sweep and
low-battery teardown of reused connections.
In startWatchingIfNeeded(), reconcileWatchers() stays inside the
cache-lock-guarded launch and evictIdleReuseConnectionsLoop() launches as
a sibling coroutine that runs while the service lives (its original #368
placement, independent of the cache-lock guard). No behavior change to
either side.

An on-device drilldown proved Gmail server-side throttles LibreMail's
connect-per-operation IMAP: every op was a fresh CONNECT+TLS+LOGIN, and
full-history backfill's body+attachment prefetch generated ~601 connections in
~22 min, tripping (and sustaining) Gmail's per-account rate/bandwidth clamp
(body download collapsed to ~4 KB/s). The `live` gauge peaked at only 5 (Gmail
allows ~15), so it is connection *volume*, not count. Outlook IMAP on the same
device opened in 2-3 s. Reusing one warm socket per account (~601 -> ~1) removes
the throttle's trigger. This wires the reuse path the #125 spike built and left
OFF (issue #357 Part 2 — connection reuse only; prefetch is a separate PR).
How it is enabled (with a safety switch):
- New `BuildConfig.IMAP_CONNECTION_REUSE` (default true) drives the production
`ImapClient` no-arg `@Inject` constructor. To disable if a server misbehaves,
flip it to "false" in app/build.gradle.kts — a build-config change, no Kotlin
edit. The internal `ImapClient(reuseConnections, reuseIdleTimeoutMillis)`
constructor stays the test/harness seam.
- Universal: applies to all providers (incl. Outlook). No per-provider caps or
throttling here — that is a separate effort (#356/#360-#364).
Hardening `ImapConnectionCache` for production (was a spike):
- Transparent stale recovery: broadened drop detection to Angus's own
`iap.ConnectionException` (and a MessagingException caused by one) — the real
signal `folder.open()` throws on a server-dropped idle socket, which the
IOException-only check missed, so the reconnect now actually fires. A dropped
reused socket is rebuilt once and the op retried, so callers see no spurious
error; a genuine app error (e.g. message-not-found) is never retried.
- Idle eviction: `evictIdle()` closes a connection unused past the reuse idle
timeout (default 5 min), swept every 2 min by `IdleService`; skips any
in-use connection.
- Teardown: `IdleService` also tears down reused connections on the low-battery
push-teardown path (#88/#89/#90), mirroring the IDLE connection teardown.
- Concurrency: one connection per account behind a per-account mutex; the
eviction sweep takes the lock non-blockingly so it never stalls or interrupts
an in-flight op. Coexists with IMAP IDLE (its own separate connection).
- PII-free AppLog on the lifecycle (open / reuse-hit / reconnect-stale / evict /
teardown) keyed by an opaque per-cache ordinal, plus the #358 ImapPerf
breadcrumb (connect~=0ms on a reuse hit).
Tests (all via the fast gate, no emulator):
- ImapConnectionCacheTest: reuse, retry-once stale recovery, narrow drop
detection, deterministic idle eviction (injected clock), teardown.
- ImapFolderOpenLatencyTest (GreenMail + counting proxy): N ops share one
connection/LOGIN; a force-dropped socket is transparently reconnected; an app
error does not reconnect; idle eviction LOGS-OUT and the next op reconnects.
- Correctness suites (ImapClientTest/ImapClientBackfillTest/MailBackfillerTest)
pinned to reuse-off to keep their connect-per-op assertions unchanged.
Fast gate green: assembleDebug, testDebugUnitTest, compileDebugAndroidTestKotlin,
lintDebug, ktlintCheck, detekt.

On Android 15+ / SDK 37 devices with 16 KB memory pages (e.g. Pixel 10 Pro XL,
and the API-37 `google_apis_ps16k` emulator image), a native `.so` not aligned
for 16 KB pages fails to load with `UnsatisfiedLinkError` at
`SQLiteConnection.nativeOpen`. With the opt-in SQLCipher encrypted cache on, this
crashed the app on every cold start (issue #359, x4 on-device) instead of
degrading, and encryption silently never applied.
Fix: DatabaseProvisioner's encryption gate now catches `LinkageError`
(UnsatisfiedLinkError and related native-link failures) when opening/converting
the encrypted cache and degrades cleanly instead of propagating the crash — it
turns `encryptCache` off (so the next start does not re-attempt and re-wipe),
clears any on-disk ciphertext the plaintext framework opener cannot parse
(resetting its now-useless seals), and opens the cache unencrypted. The cache is
a re-syncable copy of server mail, so clearing it loses nothing that cannot be
re-fetched. PII-free AppLog.w breadcrumb on the degrade path.
Dependency: no bump needed or available. The repo already pins the newest
SQLCipher it references, `net.zetetic:sqlcipher-android:4.16.0`, which
docs/play-compliance.md certifies (ELF p_align = 0x4000) as 16 KB-aligned on
every ABI; SQLCipher has shipped 16 KB-aligned binaries since well before it, and
the other two bundled `.so` files (Compose graphics-path, DataStore
shared-counter) are already 16 KB-aligned per that doc. The graceful-degrade
catch is therefore the actionable fix.
Tests:
- Unit (DatabaseProvisionerTest): a simulated native-load failure degrades to a
plaintext open without crashing, turns encryptCache off, and wipes + reseals an
already-encrypted cache.
- Instrumented (DatabaseProvisionerInstrumentedTest): a fresh encrypt-on start
loads the real SQLCipher native library and opens the keyed cache — CI's API-37
`google_apis_ps16k` 16 KB job exercises the actual `.so` load, catching any
future 16 KB-alignment regression.

Root cause: after #302's runtime-cap fallBackToPeriodicSync() stops the
dataSync foreground service, IdleService was restarted (START_STICKY
null-intent redelivery + explicit startForegroundService) and onStartCommand
unconditionally called startForeground(DATA_SYNC) while the rolling-24h budget
was still exhausted. The platform rejected the start with
ForegroundServiceStartNotAllowedException; it was uncaught, the process
crashed, and START_STICKY restarted straight back into the same rejection -- a
crash loop until the 24h window freed budget (#354).
Fix (IdleService.kt):
- onStartCommand now returns START_NOT_STICKY. Push is app-managed
(LibreMailApplication.ensurePushStarted deterministically restarts it), so the
sticky null-intent auto-restart was redundant and fired exactly when a dataSync
FGS start is illegal.
- Guard the foreground start via a new JVM-testable IdleForegroundStarter seam:
a ForegroundServiceStartNotAllowedException (caught via its IllegalStateException
supertype, so no minSdk-29 class load) degrades like the cap handler --
schedulePeriodicSync(), keep the degraded POLLING notification, stopSelf()
promptly (avoids the "did not call startForeground in time" ANR) -- instead of
propagating.
- Record the cap event (elapsedRealtime); while still inside the cap window,
onStartCommand skips the now-guaranteed-illegal foreground start entirely.
- onTimeout stop path kept fast so ForegroundServiceDidNotStopInTimeException
stays mitigated.
PII-free AppLog.w/i on the degrade paths.
Tests:
- Unit (IdleForegroundStarterTest): onStartCommand returns START_NOT_STICKY; a
rejected start is caught and routed to degrade without propagating; the cap
window skips the attempt; a non-ISE propagates.
- Instrumented (IdleServiceForegroundStartInstrumentedTest): the degrade path on
a real Context -- rejection caught, periodic-sync fallback scheduled, degraded
"instant delivery paused" notification built, watching skipped.

Adds AppLog breadcrumbs to the message-open path so a debug report can show
where the reader's spinner time goes:
- ImapClient.withStore: per-op connect vs. work timing plus a live
connect-per-op connection gauge (issue #125's provider-ceiling context).
- fetchBodyMarkingSeen: select/body/flag phase timings plus PII-free size
counts (RFC822 size, body chars, attachment count).
- MailRepositoryImpl.openMessage: end-to-end open latency plus the
cached-vs-fetched branch, keyed by accountLogRef and logSafeFolderLabel.
- ReaderViewModel: spinner-to-ready latency, split success vs. failure.
All breadcrumbs are PII-free: accounts are logged via the existing
accountLogRef hash, folders via the existing logSafeFolderLabel allowlist,
and everything else is sizes/durations/booleans only.
Fixes the 4 unit-test classes that exercise this code without mocking
android.util.Log (a throwing stub under plain JVM tests): mockkStatic(Log)

Move the traffic-control (runner-priority orchestration) job verbatim out of
.github/workflows/ci.yml into a new standalone workflow,
.github/workflows/traffic-control.yml, so the heavy CI jobs no longer depend
on it. The job's YAML (name, runs-on, timeout-minutes, permissions, env,
steps) and its documentation comment move unchanged; the decision core
.github/scripts/traffic_control.py is untouched and still unit-tested by the
traffic-control-tests job in ci.yml.
In ci.yml: removed the traffic-control job, dropped needs: traffic-control
from the five heavy jobs (static-analysis, debug-build, unit-tests, e2e,
e2e-preview) and from traffic-control-tests (its only needs, which would
otherwise dangle at a now-deleted job), and updated the now-stale header and
ci-passed comments to point at the extracted workflow.
The new workflow will be disabled pending a rebuild as a published GitHub
Action.

#350 made ci-trigger.yml dispatch ci.yml with the built-in GITHUB_TOKEN, on the
claim that a workflow_dispatch is anti-recursion-exempt so no PAT is needed. In
practice a GITHUB_TOKEN-triggered run is held in `action_required` awaiting manual
approval and never runs un-attended, so auto-updated PRs' CI never ran (stalled
#285). The original #349 design was right: dispatch with a PAT so the run executes
as the authorized owner with no approval gate.
- ci-trigger.yml: the trigger step's GH_TOKEN is now
`${{ secrets.AUTOUPDATE_TOKEN || github.token }}` (was `${{ github.token }}`).
AUTOUPDATE_TOKEN (the PAT) is REQUIRED for the scheduler; the `|| github.token`
fallback stays fail-open but only starts CI if repo settings don't gate
GITHUB_TOKEN-triggered runs.
- autoupdate.yml: branch update stays on GITHUB_TOKEN (must NOT retrigger CI --
that would re-introduce the cascade). Clarified that AUTOUPDATE_TOKEN is still
required by the repo (by ci-trigger.yml) so the secret isn't deleted.
- Corrected the now-wrong "no PAT needed / workflow_dispatch anti-recursion-exempt"
comments in ci-trigger.yml and the traffic_control.py docstrings.
updates = GITHUB_TOKEN, triggering = PAT.
Validation: all three workflow YAMLs parse clean; traffic-control unit tests still
pass (59 tests) -- the change is workflow-env only, script logic unchanged.

Resolve DatabaseModule conflict from #320: main replaced the explicit .addMigrations(...) chain with .addMigrations(*ALL_MIGRATIONS) plus an introspectable ALL_MIGRATIONS list guarded by databaseModuleRegistersEveryDeclaredMigration (registered == declared). Add MIGRATION_19_20 to ALL_MIGRATIONS so the unified-inbox covering-index migration (cache schema v19->v20) is both registered on the Room builder and satisfies that safety-net test. Schema 20.json, the v20 @Database version, and DatabaseEncryptionTest's schema-version assertion (20) are unchanged.

End the merge cascade and give the traffic-controller ownership of CI *triggering*.
- autoupdate.yml updates PR branches with the built-in GITHUB_TOKEN instead of a PAT,
so an update push no longer auto-retriggers CI (GitHub's anti-recursion rule) — the
cascade (every merge re-runs every PR, cancel-in-progress thrashing them) is gone.
- New scheduler ci-trigger.yml -> traffic_control.py --mode trigger (re-)triggers CI
for the highest-priority PR(s) whose head SHA has absent/stale checks, a few at a
time (inflight cap), in the existing P0-P9 / broken-draft priority order — a
poor-man's merge queue reusing the priority core. It runs after autoupdate finishes
(workflow_run, race-free) plus a cron backstop plus manual dispatch.
- Triggering uses workflow_dispatch, which is EXEMPT from anti-recursion, so the
built-in GITHUB_TOKEN (actions: write) starts the run — NO PAT / secret change needed.
- ci.yml gains a workflow_dispatch trigger (pr/head_sha/reason inputs) and a per-PR
concurrency group unifying pull_request and dispatch runs; its on: pull_request path
is kept so brand-new PRs, human pushes, and fork PRs always get CI (fail-open).
Pure select_triggers / classify_sha_runs decision core added to traffic_control.py with
24 new unit tests (priority order, oldest-first fairness, inflight cap, fork skip, P0
bypass+preempt, head-SHA needy classification, and a liveness/anti-starvation simulation).

Add a detekt style>ForbiddenImport rule that forbids `import android.util.Log`
so all logging flows through org.libremail.reporting.AppLog, which mirrors each
line into the debug-report RingLogBuffer. A raw android.util.Log import writes to
Logcat only and never reaches a user-reviewed DebugReport (epic #324, strangler
final step).
Excludes the AppLog facade itself (the one sanctioned wrapper) and the unit tests
that mockkStatic(Log) to verify forwarding — AppLog forwards to Log, a throwing
stub under plain JVM unit tests, so those tests must mock it; they do not bypass
the facade.

Restore (and extend to drafts) the old bash's broken-reclaim behaviour that the
initial Python refactor had dropped. runs_to_cancel now cancels an OTHER PR's
active/queued runs when EITHER:
(a) THIS PR is P0 and that PR is strictly-lower (reclaim every lower runner); OR
(b) that PR is broken/draft (effective priority 10) and THIS PR is strictly-higher
(effective priority < 10) — a wasted run any ready PR may reclaim.
P1-P9 still never bump a *normal* (non-broken/draft) lower run; a broken/draft PR
(P10) preempts nothing (nothing is strictly-lower than the bottom, and the
equal-or-higher invariant means a P10 never cancels another P10). Self / main-push /
equal-or-higher invariants unchanged.
Updates the module docstring + ci.yml comments (the "only P0 preempts" wording
becomes: P0 preempts everything strictly-lower; additionally, any strictly-higher PR
preempts a broken/draft run) and the job step/permission/needs comments. Adds unit
tests: P3 reclaims a broken P10 run and a draft P10 run; P3 does not bump a normal P5
run; a P10 self preempts nothing; plus an end-to-end P5-reclaims-draft-then-waits
scenario. 37 unit tests pass; ci.yml parses clean; --dry-run shows a P3 cancelling a
draft (and broken) run while still yielding to a higher P1.

The priority-based runner orchestration ("traffic-control") lived as a large
inline-bash step in ci.yml — a two-pass preemption + hold-back script that was
effectively untestable in YAML. Move it into .github/scripts/traffic_control.py,
structured as a pure decision CORE + a thin gh-I/O SHELL:
* Pure functions (no network/clock/subprocess), unit-testable in isolation:
- effective_priority(pr): lowest-numbered P0-P9, default P5; broken OR draft => 10.
- runs_to_cancel(this_pr, all_prs, self_run_id): PASS 1 — run ids to cancel,
empty unless THIS PR is P0; only strictly-lower running/queued runs; never self
(by number or run id), never equal-or-higher.
- wait_blockers(this_pr, all_prs): PASS 2 — yield to any strictly-higher PR with
an active/queued run, and to same-level peers ordered ahead (running-first,
then oldest createdAt). Empty => proceed.
* Shell (run_live): gathers the snapshot via gh, applies cancels, runs the bounded
hold-back poll loop; always exits 0. --dry-run feeds the core a snapshot JSON and
prints decisions with zero network.
* No jq/bash dependency (cross-platform, per the repo's Python-stdlib convention).
ci.yml's traffic-control job now checks out the repo and runs the module. Job
permissions gain `contents: read` (for checkout) alongside the existing
`actions: write` / `pull-requests: read`; env and downstream `needs:` wiring
unchanged; step stays `continue-on-error`.
33 stdlib unittest cases cover priority resolution, P0-only preemption, the
self/main/equal-or-higher invariants, and the same-level running-first/oldest
ordering.
Behaviour is preserved except the ticket's refinements: (1) drafts now count as
P10 (bottom); (2) an explicit same-level running-first-then-oldest tiebreaker; and
(3) per the ticket's order-of-operations, ONLY P0 preempts — the old bash also let
any higher-priority PR cancel a `broken` target's run, which no longer happens
(a broken/draft run is only cancelled by a P0, via the same strictly-lower rule).

The sync engine (MailSyncer, MailBackfiller, MailPruner, and their WorkManager
workers) was completely silent, so a submitted debug report showed nothing
about whether sync ran, how much it fetched, or why it was skipped. Add
net-new AppLog breadcrumbs at each class's lifecycle points per the #324
strangler-migration plan: sync start/done/failed and per-folder fetch counts,
backfill slice start/done and per-folder page counts, prune's removed count,
and each worker's cache-locked deferral and success/retry outcome (the retry
path now also carries the scrubbed failure throwable via AppLog's #325
overloads).
Every breadcrumb is PII-safe by construction: accounts are identified only via
accountLogRef(account.id) (never the id or email directly), and a new
logSafeFolderLabel() helper logs a folder's name only when it matches a fixed
allowlist of known system folders (INBOX, Sent, Drafts, Trash, Spam/Junk,
Archive, and their common provider variants) — every other folder, however
nested or named, logs as a fixed placeholder.
Adding logging to these previously-silent classes meant every existing test
exercising them now hits android.util.Log (a throwing stub under plain JVM
unit tests), so each affected suite gains the same static Log mock already
established by AppLogTest/SendWorkerTest/ImapClientTest.

Migrate AppLockViewModel (9 sites) and AccountSetupViewModel (1 site) off
raw android.util.Log onto the AppLog seam (#325), so their diagnostic
lines land in the RingLogBuffer and reach a submitted DebugReport instead
of only Logcat. Adds three new breadcrumbs that were previously silent:
auth-seal unlock success, the clear-cache-and-restart recovery trigger
(with the disableAppLock flag), and every onForeground LockAction
decision. AccountSetupViewModel's success path also now logs "Outlook
account added" (no email). None of these call sites carry PII; where a
throwable is attached, AppLog's StackTraceScrubber redacts it before it
reaches the buffer.
Both ViewModel test suites now install a real RingLogBuffer and assert
against it instead of `verify { Log... }`, including dedicated no-PII
assertions (a known test email never appears in a recorded line). A
minimal `mockkStatic(Log::class)` stub stays in both test files' shared
setUp — AppLog still forwards to the real android.util.Log internally,
which throws "not mocked" in JVM unit tests when uninvoked; the not-yet
-landed guard-rule ticket (#331) will need to reconcile that with a
repo-wide "no raw Log outside AppLog.kt" rule.

Migrate ImapClient/SendWorker/IdleService off raw android.util.Log to AppLog,
per the debug-logging strangler epic (#324), so their diagnostics reach the
RingLogBuffer (and a submitted DebugReport) instead of logcat-only:
- ImapClient: IDLE connect + IDLE push (message count) breadcrumbs.
- SendWorker: outbox-drain count on entry, per-message sent/failed result,
and the existing Graph->SMTP fallback warning.
- IdleService: IDLE watch start, cache-locked defer, and the existing
IDLE-dropped/retrying warning.
Also closes#297: SendWorker and IdleService logged the raw account.email via
Log.w on the Graph->SMTP fallback and IDLE-drop paths. Both now log
accountLogRef(account.id) instead -- a short, stable, non-reversible
per-account reference -- so the account's email never reaches Logcat or a
report.
Rewrites ImapClientTest/SendWorkerTest to install a real RingLogBuffer via
AppLog.install(...) and assert on its contents (migrated calls + new
breadcrumbs), instead of verifying a mocked Log; every assertion also checks
no line carries the test account's email, regression-covering #297. Adds a
SendWorkerTest case that drives a real SmtpSender against an in-process
GreenMail SMTP server end to end. android.util.Log is still stubbed (by
fully-qualified name, without importing it) where AppLog's Logcat passthrough
would otherwise crash the unmocked Android stub in a JVM test.

Migrates the DB/keystore area's raw android.util.Log calls to AppLog so
key-invalidation and DB-conversion breadcrumbs land in the process
RingLogBuffer (and thus a user-reviewed debug report) even in release
builds, where Log.d is otherwise stripped from Logcat only.
- DatabaseKeyCipher: 4 auth-bound-key decision points (encrypt retry,
isInvalidated's three branches) now log via AppLog.d(tag, msg, e).
- DatabaseEncryption.migrate: adds an AppLog.i "converting local cache
database (targetEncrypted=...)" breadcrumb at the start, alongside the
existing "converted" completion line now routed through AppLog.d.
- AccountDataMigrator: the "moved account tables into the account
database: $present" breadcrumb (table names only) now routed through
AppLog.d.
No PII or key material is logged; table-name sets and boolean flags only.
Adds instrumented tests (DatabaseKeyCipher is device-only and
behavior-preserving, so no new test there) asserting the breadcrumbs
land in a RingLogBuffer and never contain the seeded email, secret, or
passphrase.

The API 37 preview E2E boot has flaked twice (#285, #333) with only
"did not boot within 300s" and no root-cause signal. Add rich boot
diagnostics by default, kept in parity between CI and the local
hand-provisioning script (api37_e2e.py):
- Launch the emulator with `-verbose -debug init,avd_config,kernel`
(diagnostics only; no boot-affecting flag changed), still redirecting
to $EMU_LOG.
- Stream `adb logcat -v time` to a file from the moment the device
registers (via `adb wait-for-device logcat`, backgrounded).
- On a boot timeout, dump accel-check, /dev/kvm presence, GPU mode,
free mem/disk, the AVD config.ini and the emulator.log tail; CI writes
these to a boot-diagnostics file, the local script prints them.
- CI uploads emulator.log + logcat.txt + boot-diagnostics.txt as an
artifact with `if: always()` so they survive a timeout/cancel, and
prints a concise summary (accel/KVM status + last 50 lines of
emulator.log) to the step log.
The existing 2-attempt boot retry + boot-completed wait loop are
unchanged; the diagnostics are additive.

Migrate RestartActivity's one raw Log.w site to AppLog, clearing the
final raw android.util.Log site outside the auth/lock, DB/keystore,
connectivity/send, and sync-engine migration areas so the codebase is
ready for the detekt android.util.Log guard (#331).
RestartActivity runs in the separate :restart trampoline process,
where LibreMailApplication.onCreate returns early and never calls
AppLog.install, so this breadcrumb reaches Logcat only, never a
DebugReport. The migration is guard-compliance + Logcat-consistency
only; behavior is unchanged since AppLog forwards to Logcat.
RestartActivity is DEVICE-ONLY (multi-process kill/relaunch), so a
JVM buffer-capture test doesn't apply here. Added
RestartActivityLoggingTest, which instead pins the null-buffer shape
this call runs under in the trampoline process: it forwards to
Logcat and no-ops the buffer cleanly.

Port the last bash dev-script (local_instrumented.sh) to a cross-platform,
stdlib-only Python 3 script (local_instrumented.py), matching api37_e2e.py's
style, and rewire the /preflight skill's local E2E off the GMD
apiXXDebugAndroidTest tasks (which fail locally under AEHD 2.2) onto it.
- local_instrumented.py preserves the .sh's behavior exactly: comma-separated
test-class CLI arg, pre-boot orphan-kill, manual cold-boot of the dev36 AVD
(no GMD, no snapshot), targeted connectedDebugAndroidTest, and the EXIT-trap
teardown (now try/finally + atexit + SIGINT/SIGTERM handlers, idempotent).
Exit codes 0/2/3/4 preserved.
- Cross-platform process kill abstracted per-OS: taskkill /F /IM on Windows,
pkill -f qemu-system on *nix; process listing via tasklist / ps ax.
- Teardown hardened vs the .sh: it now also reaps the emulator *launcher*
image, not just qemu -- the Windows -no-window emulator spawns a sibling
emulator.exe that briefly outlives the qemu VM, which a qemu-only sweep left
as an orphan on return (caught by the smoke run).
- SKILL.md + CLAUDE.md: replace the local api35/api36 GMD E2E steps with
local_instrumented.py; CI's own multi-API matrix is untouched. CLAUDE.md
documents the Python-first dev-script convention.
Validated: py_compile, argparse (--help / no-arg exit 2), and a guarded
emulator smoke run of org.libremail.data.local.DatabaseEncryptionTest -- boots,
passes, and tears down clean (no qemu/emulator orphan on return).

Scope :app:jacocoTestReport's denominator to the JVM-testable surface and
add a :app:jacocoTestCoverageVerification no-regression gate that shares the
same classDirectories/executionData/sourceDirectories, wired into both the
`check` lifecycle task and CI's unit-test job (part of the `CI passed` gate).
Excluded from the denominator (structurally unreachable from a JVM unit
test): Compose screen/component render code, Android framework entry points
(*Activity/*Service/Application/*BackupAgent), Hilt DI (**/di/**), and the
src/debug cold-open probe. Kept in scope: ViewModels, repositories, mappers,
DAOs, utils, richtext, mail, reporting logic, and the six WorkManager Workers.
Corrects PR #292, which excluded **/*Worker*: SyncWorker, BackfillWorker,
PruneWorker, SendWorker, ReportPurgeWorker and ReportUploadWorker are all
directly unit-tested, so they stay counted in both numerator and denominator
(only their Hilt wiring, WorkManagerModule, is excluded, via **/di/**).
Baseline: 80.21% line (4838/6032). Floor: 0.79 (~1.2% headroom) so ordinary
noise doesn't red-flag it while a real drop fails. Manual ratchet for now:
bump the floor up in the same PR when coverage rises materially.

MIGRATION_19_20 (issue #187) bumped the Room cache schema to version 20,
but DatabaseEncryptionTest.schemaVersionIsCarriedOntoTheEncryptedFile still

DatabaseEncryption.migrate() carries PRAGMA user_version dynamically

Room open now stamps 20, so v20 genuinely survives the conversion. Update the
expected constant to 20; the assertion's intent (the version survives the

#311: append the `id` primary key as a tiebreaker to the four paged MessageDao
`ORDER BY timestampMillis DESC` queries for a total order, so rows sharing a second
(bulk mail) can't duplicate or skip across a LIMIT/OFFSET page boundary. Pure query-text
change: the exported Room schema (identityHash) is derived from table/index structure,
not @Query SQL, so no schema re-export or version bump; id is already in the projection,
so no new index.
#312: expose the registered migration list as DatabaseModule.ALL_MIGRATIONS (spread into
addMigrations) and assert in MigrationTest that it equals the reflectively-discovered set

MailSyncConcurrencyTest's fake DAO. Instrumented MessageDaoTest + MigrationTest (31 tests)
green on a local emulator; unit tests + androidTest compile + ktlint + detekt green.

ImapClient.deleteMessage and moveMessages flagged the target \Deleted then
called the untargeted Folder.expunge(), which permanently removes EVERY
\Deleted-flagged message in the folder — not just the intended UIDs. That is a
data-loss window whenever a second client, Gmail, or a partial earlier move has
left other messages flagged \Deleted. The repository's batch delete/expunge and
trash-fallback paths also looped single-UID deleteMessage, paying N logins + N
expunges for an N-message selection.
Add a batch deleteMessages(uids) that opens the folder once, flags the matched
messages \Deleted, and issues a single targeted UID EXPUNGE (RFC 4315) via
IMAPFolder.expunge(Message[]) through a shared expungeTargeted() helper. Route
moveMessages through the same helper, delegate single-UID deleteMessage to
deleteMessages, and route MailRepositoryImpl.expunge and the moveByRole trash
fallback through the batch method. moveToFolder already batches via moveMessages,
so it inherits the targeted expunge.
On a server without UIDPLUS, Angus raises "UID EXPUNGE not supported" rather than
silently falling back to the unrelated-mail-destroying untargeted expunge — a
loud failure is the safe outcome. Gmail, Outlook, and GreenMail all advertise
UIDPLUS.
Tests (GreenMail, no emulator): deleteMessages/moveMessages expunge only the
given UIDs and spare other \Deleted-flagged mail; a batch delete of three
messages opens exactly one connection and pays one LOGIN.

exchangeToken's authorization-code exchange already requests
`openid email offline_access $OUTLOOK_SCOPE`, so the returned access token
is an outlook.office.com token usable for IMAP verification and the AuthState
already carries the refresh token and expiry. The immediate follow-up
refreshForScope(authState, OUTLOOK_SCOPE) was a second round-trip for the
same resource that only rotated the just-issued refresh token and added a
needless onboarding failure point (a transient network error there failed
sign-in after consent + code-exchange had already succeeded).
Build OAuthResult directly from the code-exchange tokenResponse
(accessToken + authState.jsonSerializeString()), dropping the extra refresh.
The durable AuthState is still serialized and persisted for later token
refresh; the Graph token remains a distinct resource minted on demand via
freshGraphToken.

A crash report captured throwable.stackTraceToString() verbatim, so mail/network
exceptions (Jakarta Mail, java.net) could embed server host:port tokens and account
emails/usernames in the report's stackTrace field — violating the PII-free-reports
constraint. Add StackTraceScrubber, applied in DiagnosticsCollector before the trace
enters toSubmissionPayload()/toStorageJson(): it keeps the non-PII value (exception
class names + every frame's class/method/file/line) and drops each header line's
free-text message (where hostnames/usernames live), then redacts any residual email
or host:port left on a wrapped continuation line. Frame lines are untouched, so a
frame's File.kt:42 is never mistaken for a host:port.
ReportStore did MutableStateFlow(scan()) in its constructor — a dir list + read +
JSON-parse of every stored report. As an eager @Singleton dep of CrashReporter, whose
install() runs on the MAIN thread in Application.onCreate(), this was main-thread disk
I/O that grows with the 30-day retention. Seed the flow empty and dispatch the initial
scan to an injectable scope (Dispatchers.IO by default); reactive consumers update when
it lands, and writes still re-scan synchronously so a crash-time save is never lost.
Tests: StackTraceScrubberTest (host/ip/port/email dropped from a ConnectException +
auth-failure trace while classes/frames survive; regex redaction of a continuation
line; null-message trace preserved verbatim); DiagnosticsCollector end-to-end scrub
test; ReportStore empty-seed + off-thread populate via a StandardTestDispatcher. Store
constructions in existing tests use an Unconfined scope to keep their synchronous
reopen semantics.

#309: AccountDao no longer uses @Insert(REPLACE). New insertIfAbsent (IGNORE)

outlook:<email>) therefore no longer cascade-deletes its account_settings +

case-insensitive), and the whole address for the consumer providers (Gmail,
Yahoo, iCloud, AOL, Outlook). Applied at every id-derivation site
(MailProvider.createAccount, Account.outlook, ManualSetupViewModel) so
differently-cased addresses can't spawn duplicate accounts. The displayed email
keeps the user's casing.
#299: deleteAccount collects the account's message ids and draft attachment URIs

IdleService runs continuously as a FOREGROUND_SERVICE_TYPE_DATA_SYNC
foreground service (push is on by default). With targetSdk 37, Android 14+'s
dataSync FGS runtime cap (~6h per rolling 24h) calls Service.onTimeout(...)
and then force-stops the service — throwing a system FGS-timeout exception —
if it doesn't stop itself. IdleService overrode onStartCommand/onDestroy/onBind
but not onTimeout, so after ~6 cumulative hours push silently died and the app
hit the exception; on API 35+ the budget is cumulative and a restart can't
recover it until the next 24h window.
Override both onTimeout(startId) (deprecated, API 34) and
onTimeout(startId, fgsType) (API 35+); both route to a clean shutdown that
re-asserts the already-scheduled 15-minute periodic sync, swaps the persistent
notification to a degraded "paused" text and DETACHes it so it survives, then
stopForeground(DETACH) + stopSelf so we never leave a dataSync FGS running past
its cap (the exact condition the platform kills on). This mirrors the existing
low-battery PushMode.POLLING fallback.
The push-status text choice is pulled into a pure PushStatusNotification.statusTextRes
seam and unit-tested on the JVM; the built notification's new timed-out text is
covered by PushStatusNotificationInstrumentedTest.

The wrapper jar path was resolved from the script's own location, but
gradlew picks the *project* to build from the process's current
directory, not from its own script location. Invoking the helper from
a CWD outside its tree (e.g. another worktree) silently built the
wrong repo's :app, once observed as a ClassNotFoundException for a
test class that only existed in the intended worktree.
cd to the already-resolved repo/worktree root before invoking gradlew
so connectedDebugAndroidTest always targets the correct tree
regardless of the caller's CWD. Update the README's usage note to
match.

LocalClipboardManager/ClipboardManager are deprecated in Compose in favor
of LocalClipboard's suspend Clipboard API. Migrates the one call site,
ReportReviewScreen's "Copy report" action: LocalClipboardManager.current
becomes LocalClipboard.current, and the synchronous
clipboard.setText(AnnotatedString(...)) becomes a suspend
clipboard.setClipEntry(ClipEntry(ClipData.newPlainText(...))) run inside
the existing rememberCoroutineScope(). The clipboard interaction is
pulled into a small internal suspend function, copyReportPayloadToClipboard,
so it's unit-testable against a mocked Clipboard without an emulator.

The paged "All inboxes" query (MessageDao.pagingUnifiedFolderSummaries:
WHERE folder = ? AND inInbox = 1 ORDER BY timestampMillis DESC) had no
folder-leading index, so it SCANned the whole messages table via
index_messages_timestampMillis and filtered folder/inInbox per row.
Add a (folder, inInbox, timestampMillis) index so the two equality
predicates become an index seek and the ORDER BY is supplied by the
index. EXPLAIN QUERY PLAN for the query goes from
SCAN messages USING INDEX index_messages_timestampMillis
to
SEARCH messages USING INDEX index_messages_folder_inInbox_timestampMillis (folder=? AND inInbox=?)
with no temp B-tree sort.
Pure additive index (no column/table change): bump the Room DB to v20
with MIGRATION_19_20 (CREATE INDEX IF NOT EXISTS), register it in
DatabaseModule, export 20.json, and add a MigrationTest that runs the
migration and asserts the index shape plus the SEARCH plan on real
Android SQLite.

Coverage lane 4 (#249) flagged reporting/push classes as unreachable by tests.
Add minimal, behaviour-preserving seams and the tests they unblock (issue #257):
- ReportUploadScheduler: inject Provider<WorkManager> (mirroring SyncScheduler)
instead of calling the WorkManager.getInstance static that MockK can't stub on
the abstract WorkManager (AbstractMethodError). New ReportUploadSchedulerTest
pins the per-report unique-work name + REPLACE policy.
- ReportUploadWorker: take the ingest endpoint via a new @DebugReportEndpoint
qualifier (provided from BuildConfig.DEBUG_REPORT_ENDPOINT in ReportingModule)
rather than reading the BuildConfig static inline. New ReportUploadWorkerHttpTest
drives the transmit path against an in-process JDK HttpServer on loopback and
covers 2xx success + delete, 4xx failure, 5xx retry/attempt-cap, and network
error. Production value is unchanged (empty by default).
- IdleService: extract the foreground-notification channel + push-mode-to-text
logic into PushStatusNotification. New PushStatusNotificationInstrumentedTest
asserts channel importance and the IDLE/POLLING notification text with a real
application Context (never a mocked Context).

Guards the SQLCipher cold-start crash fixed in 592a797 (bug #210): a cold
process opening an already-encrypted cache with nothing to convert reached
Room's keyed nativeOpen with the native .so unloaded and crash-looped with
UnsatisfiedLinkError. Every existing on-device test (DatabaseEncryptionTest,
DatabaseProvisionerInstrumentedTest, DatabaseModuleInstrumentedTest,
AccountDataMigratorTest) runs a conversion first, which loads the process-global
library in-process, masking the bug exactly as production did.
System.loadLibrary is process-global, so the instrumentation process can no
longer observe a cold open once it has minted the encrypted fixture. This adds
ColdOpenCacheProbe -- a debug-only ContentProvider declared with
android:process=":coldopen" -- to host the open in a separate, pristine app
process. The test mints the encrypted fixture in the instrumentation process
(a file created by a prior encrypted DB instance) and drives the cold open in
the :coldopen process via ContentResolver.call, mirroring DatabaseProvisioner's
encrypted branch + DatabaseModule's open lambda against the real DatabaseEncryption,
DeferredOpenHelperFactory and SupportOpenHelperFactory. A cold probe (a keyed open
with no preceding load, asserted to throw UnsatisfiedLinkError) makes the isolation
self-verifying: the test fails rather than passing hollow if the library was
already loaded in the harness process.
Verified locally on an API 36 emulator (connectedDebugAndroidTest): 1 test,
0 failures.

Local Gradle Managed Device tasks (apiXXDebugAndroidTest) fail on this machine:
GMD's AVD snapshot step times out under AEHD 2.2
(AvdSnapshotHandler$EmulatorSnapshotCannotCreatedException), though the emulator
itself boots fine. CI is unaffected (it uses connectedDebugAndroidTest, not GMD).
Add .claude/skills/preflight/local_instrumented.sh, which cold-boots ONE emulator
by hand (-no-snapshot, no GMD) and runs :app:connectedDebugAndroidTest filtered to
a targeted set of test classes -- the same technique CI and api37_e2e.py already use.
The helper is deliberately targeted (the full ~114-test suite tends to wedge mid-run
on this box) and enforces emulator hygiene: it force-kills stray qemu/emulator
processes before booting, tears the emulator down afterward, and exits non-zero if an
orphaned qemu-system-x86_64-headless.exe survives -- accumulated orphans have frozen
this machine. Ships with a documented header and a short sibling README.

Adds instrumented Compose UI tests for the screens #250/#274 left uncovered,
so lane 6's ui-package coverage ratchet (#251, >=95%) can pass:
- ColorSwatchRow (compose/format): none entry + swatch rendering, selection
callbacks, and selected-state semantics.
- LockScreen: locked title/body, optional error text, unlock callback.
- AddAnotherAccountScreen: confirmation + both onboarding choices.
- SignatureEditScreen: real ViewModel over an in-memory Room-backed
SignatureRepository — new-vs-edit title, create/update round-trips.
- ReportReviewScreen: real ViewModel over a file-backed ReportStore (submitter
stubbed disabled) — disclaimer/fields render, Submit gated on comment length
+ email validity, discard deletes and leaves.
- AppPasswordSetupScreen: real ViewModel over FakeAccountRepository — provider
chrome + credential add, and the app-password help link asserted via
Espresso-Intents (mirrors AccountPickerScreenTest) so no real browser opens.
All 23 tests pass locally on an API 36 emulator.

The compose FAB does not render reliably under a never-completing refresh==Loading pager (flaked as not-displayed, not-found, then waitForText-timeout across CI runs).

DatabaseProvisionerTest (mocked) and DatabaseProvisionerInstrumentedTest
(real SQLCipher) both pin that prepareCache() loads SQLCipher's native
library for the encrypted branch, but neither exercises
DatabaseModule.provideDatabase itself — the instrumented one opens
through a hand-rolled SupportOpenHelperFactory, bypassing the branch
that actually maps CacheOpenMode to a real factory. A regression that
breaks that wiring would slip through both existing guards.
Adds DatabaseModuleInstrumentedTest, calling provideDatabase directly
and driving the first real open through its own
DeferredOpenHelperFactory lambda: the encrypted branch loads the
native lib and opens a genuinely-encrypted file, the plaintext branch
never touches the native lib, and a fault-injected load failure
proves the keyed open is causally gated on the load rather than just
usually preceded by it.

Extends #274's AccountPickerScreenTest with an Espresso-Intents check that
tapping Outlook fires AppAuth's authorization intent. AppAuth always routes
through its own AuthorizationManagementActivity before it ever reaches a
real browser, so that component name is the one characteristic of the
launch that's both guaranteed and installed-browser-independent; matching
it also lets the test stub a canceled result so no real browser opens.
Verified against the real OutlookAuthManager + AppAuth 0.11.1 on a
google_apis API 29 emulator (the same image CI's managed devices use).
Redirect handling, token exchange, and account creation stay out of scope
per #276.

emptyState_isHidden_whileTheInboxPagerIsStillLoading asserted the compose
FAB with assertIsDisplayed(), but MailboxScreen renders no loading
affordance in this exact scenario (isSyncingFolder only flips true from
selectFolder(), which this test never calls), so there is nothing else
guaranteed visible while refresh == Loading. The FAB is unconditionally
composed in Scaffold's floatingActionButton slot regardless of loading
state, so its role here is only to prove the screen composed rather than
crashing or rendering blank. Swap to assertExists(), which checks presence
in the semantics tree without requiring on-screen visibility, and keep the
core assertion (mailbox_empty assertDoesNotExist()) that verifies the
actual issue #219 behavior.

Rebase collision with the accountRepository param added to DiagnosticsCollector's

Returning from the reader/message screen to the inbox briefly showed the
"No messages" empty state and reloaded: the inbox's only Paging presenter
(collectAsLazyPagingItems) is torn down while a message is open, so the
cachedIn pager loses its downstream collector. Opening an unread message
writes setRead, invalidating the Room PagingSource; with nothing collecting,
the fresh generation only cold-loaded once the inbox re-entered composition —
a multi-second stall plus a one-frame empty-state flash. (The empty-state
gate itself already landed with #214/#223.)
Add an always-on, invisible PagingDataPresenter in MailboxViewModel that stays
subscribed to the cached paged flow across the reader visit (collectLatest
hands each new generation to collectFrom), so the post-setRead generation
loads in the background and the return replays a full window with no empty
frame.
Tests:
- MailboxViewModelTest: a real, invalidatable Pager proves the pager loads its
initial window and reloads after invalidation with no UI collector attached.
- MailboxScreenTest: the empty state is held back while refresh is Loading and
shown only once the pager settles genuinely empty, driven via PagingData.from
with explicit LoadStates through a new FakeMailRepository paged override.

AccountDaoTest (added by #270's coverage lane) asserts email ordering,
but AccountDao.observeAll()/getAll() now order by the user-defined
sortOrder (#164) with no tiebreaker. Two accounts inserted via plain
upsert() both land on the default sortOrder (0), so they came back in
rowid/insertion order instead — failing the test deterministically on
CI (API 30 & 31): expected [ada, zed], got [zed, ada].
Add `email` as a secondary ORDER BY key. Real accounts always get
distinct sortOrders via insertAtEnd()/reorder(), so drag order is
untouched; only equal-sortOrder rows now fall back to a stable,
deterministic email order. This also matches the "rank by email"
convention already used to seed sortOrder in ACCOUNT_MIGRATION_1_2 and
AccountDataMigrator.copyAccountTables, so the existing coverage test
passes unchanged. No schema/migration change is needed since this
only edits a @Query string, not the entity.

locked state is reproduced with no device auth by mocking SettingsRepository (the

DatabaseProvisionerInstrumentedTest crashed in @Before setUp() on API 31/32 with ArrayIndexOutOfBoundsException (length=0; index=0), passing on API 29. The stack shows the throw is entirely in the test harness: mockk<Context>() -> MockK JvmMockFactoryHelper.isKotlinInline -> kotlin-reflect ReflectJavaMember.getValueParameters, which indexes parameterAnnotations[0] on an empty array. Mocking android.content.Context makes MockK walk the whole framework class with kotlin-reflect, and on Android 12/12L ART returns a parameter-annotation array shorter than the parameter-type array for some Context method, so kotlin-reflect throws. Production DatabaseProvisioner/DatabaseEncryption code never runs. Replace the mockk<Context> with a real ContextWrapper(appContext) that overrides getDatabasePath to route the cache file to the test DB and delegates everything else, sidestepping the framework-class reflection walk. Verified 3/3 pass on the dev36 GMD emulator; API 31/32 left to CI (images not installed locally).

PR #234 (issue #232, merged into this branch) bumped the Room schema 18->19 and made the MessageDao search queries match Unicode-casefolded *Fold columns. Two lane-3 tests were stale against it:
- DatabaseEncryptionTest.schemaVersionIsCarriedOntoTheEncryptedFile hardcoded the pre-#234 schema version 18; bump to 19 (matches LibreMailDatabase version = 19).
- MessageDaoTest's search-summary tests inserted MessageEntity fixtures without populating the new senderFold/senderEmailFold/subjectFold/snippetFold columns, so the casefolded LIKE matched nothing ([]). Populate them in the message() helper via lowercase(), mirroring production (Mappers.toEntity + MessageDao.updateHeaderContent/updateBody).
MigrationTest already covers 18->19 (migrate18To19_addsAndBackfillsCasefoldSearchColumns plus the auto-discovered full-chain replays), so no change there. Verified: targeted connectedDebugAndroidTest of MessageDaoTest+DatabaseEncryptionTest+MigrationTest on the API 36 emulator = 32 tests, 0 failures.

The #164 reorder-accounts feature switched addImapAccount/addOutlookAccount from accountDao.upsert(...) to accountDao.insertAtEnd(...) (a @Transaction default method that stamps sortOrder before delegating to upsert), but the test's mocks/verifies still targeted upsert directly. Since MockK doesn't invoke a mocked interface's default method body, the unstubbed insertAtEnd call threw MockKException. Updated the stub/verify pairs in both add-account happy-path tests and the exactly-0 verifies in both failure-path tests to reference insertAtEnd.

Only P0 preempts in-progress runs (emergency reservation). P1-P9 no longer
cancel lower-priority runs; instead traffic-control holds back (bounded poll,
kept under timeout-minutes) while strictly-higher-priority PRs still have
active/queued CI runs, so their heavy jobs reach the runner queue first.
New `broken` label forces effective priority below P9 (sentinel 10): a broken
PR never preempts (even if also labelled P0 -- broken wins) and always yields,
and because its run is wasted, ANY higher-priority PR (not just P0) may cancel
its in-progress run to reclaim the runner. Net rule: a strictly-lower run is
cancelled iff (self is P0) OR (target is broken); otherwise yield.
All existing safety preserved: never main/push runs, never our own run, never
an equal-or-higher-priority PR; PR-controlled strings via env/jq only;
continue-on-error + set +e + always exit 0; traffic-control stays a
non-required best-effort job and ci-passed is unchanged.
Validated with actionlint and a mocked-gh + fake-clock logic harness.

The e2e Gradle Managed Device group spans api29-36 and org.gradle.parallel=true
is set, so a local e2eGroupDebugAndroidTest (or preflight's api36DebugAndroidTest)
can launch several emulators at once. They contend for the same VT-x/HAXM
virtualization slot on a single machine and hang at 0% CPU with "another
emulator instance is running". Set
android.experimental.testOptions.managedDevices.maxConcurrentDevices=1 in
gradle.properties to force GMD emulator runs serial locally.
CI is unaffected: its e2e matrix boots one emulator per API level on separate
GitHub Actions runners via reactivecircus/android-emulator-runner and
connectedDebugAndroidTest, not these Gradle Managed Device tasks, so the cap
doesn't apply there regardless.

Change the api37_e2e.py emulator launch from `-gpu swiftshader_indirect`
to `-gpu auto-no-window`. For a LOCAL run the host GPU is faster and
auto-no-window is the mode that boots cleanly on this machine; CI's
e2e-preview keeps swiftshader_indirect for headless-runner determinism.
This is now the single deliberate divergence from e2e-preview; the image
string, provisioning, boot sequence, and every other emulator flag stay
in lockstep. Updated the script comments/docstring, SKILL.md, CLAUDE.md,
and the build.gradle.kts managed-devices comment to document it.

Per the repo owner's decision, preflight now runs the API 37 preview
emulator locally instead of leaving it to CI. Since there is no Gradle
Managed Device DSL path to the nonstandard android-37.0 /
google_apis_ps16k image, add a stdlib-only, cross-platform Python 3
helper (.claude/skills/preflight/api37_e2e.py) that mirrors CI's
e2e-preview job EXACTLY: same system image string
(system-images;android-37.0;google_apis_ps16k;x86_64), same emulator
flags, same provisioning/boot sequence. It installs the image via
sdkmanager, creates the AVD via avdmanager, cold-boots headless, waits
for sys.boot_completed, runs :app:connectedDebugAndroidTest, then tears
the emulator + AVD down. Cross-platform: per-OS tool discovery/suffixes
and cmd /c wrapping for Windows .bat launchers.
Update SKILL.md + CLAUDE.md so preflight runs api35 + api36 (GMDs) +
api37 (this script), and the app/build.gradle.kts managed-devices
comment now points at the script. Add a caveat that emulators need a
free hardware hypervisor (VT-x/WHPX) — shut down VirtualBox/other VMs
first or the AVD hangs at 0% CPU.
Validated syntactically only (python -m py_compile + ast.parse +
argparse --help); no emulator was booted and no build was run, to avoid
contending with an in-progress api36 run.

Extend the local preflight gate from api36 (the sole latest-API GMD
run) to api35 + api36, the top two stable levels in the E2E matrix.
Both Gradle Managed Devices already existed in app/build.gradle.kts
(the api29..36 loop) — confirmed via `:app:tasks --group verification`,
no emulator run needed.
API 37 (preview) was investigated but NOT added as a GMD: its only
published system image is the nonstandard "android-37.0" /
google_apis_ps16k pairing that ci.yml's e2e-preview job installs by
hand via sdkmanager. ManagedVirtualDevice's apiLevel (Int) builds
"android-<N>" and apiPreview (codename) builds "android-<Codename>" —
neither produces "android-37.0", the same gap ci.yml documents as why
reactivecircus/android-emulator-runner can't provision it either.
docs/perf/issue-124-unified-inbox-paging.md independently corroborates
this: its API 37 measurements used a physical Pixel, not an AVD. There
is no api37DebugAndroidTest task to run, so it stays CI-only
(e2e-preview) until a managed-device-compatible image ships; the
comment above testOptions.managedDevices in app/build.gradle.kts now
documents this in detail for the next person who looks.
.claude/skills/preflight/SKILL.md and CLAUDE.md are updated to run
both api35DebugAndroidTest and api36DebugAndroidTest as part of the
required gate, with the API 37 gap called out inline.

Add a lightweight `traffic-control` job that runs first (the heavy
build/E2E jobs `needs:` it) and preempts contended runners by PR
priority. It reads the triggering PR's P0–P9 label (P0 = highest,
P9 = lowest; default P5 when unlabeled) and cancels the in-progress /
queued CI runs of strictly-lower-priority OTHER open PRs, freeing their
runners for the higher-priority PR.
Safety: never cancels main/push runs, the PR's own run, or an
equal-or-higher-priority PR — only strictly-lower-priority OTHER open
PRs' active CI runs. The job is best-effort (every gh call guarded,
always exits 0, step is continue-on-error) and is NOT part of the
`CI passed` merge gate. `ci-passed` now also treats a `skipped` heavy
job as a gate failure, so a (should-never-happen) traffic-control
failure blocks the merge fail-safe rather than passing it untested.

The auto-submit crash prompt over-triggered: it re-surfaced the newest saved
crash report on every launch, with no age bound, so a pre-update crash kept
popping "LibreMail crashed" long after the crash was fixed (#255).
Gate StartupReportViewModel.pendingCrash so a crash is auto-offered:
- first re-open only — dismiss() now persists a "surfaced" marker instead of an
in-memory-only hide, so a report is offered at most once across launches; it
stays in the store (still listed in Problem Reports) and only discard() deletes.
- < 24h only — inject a clock provider and filter to createdAtMillis within 24h.
- legitimate crash only — reports come solely from CrashReporter's uncaught-
exception handler, so update / force-stop / user-close create none; made
explicit and covered by a test.
The marker is a minimal additive `surfaced` flag on DebugReport (persisted in
storage JSON, kept out of the submission payload; a missing flag = not surfaced)
plus ReportStore.markSurfaced(id). Extracted StartupCrashPrompt from LibreMailApp
so the real dialog + gating is E2E-testable.

In age-based retention, MailSyncer fetched the newest-N headers but only capped that window by the
retention COUNT, not the age cutoff. On a low-traffic mailbox whose newest-N span older than the
cutoff, each sync re-inserted messages the age pruner had just deleted, and the next prune deleted
them again — a churn loop of wasted DB writes + prune deletes (issue #193).
Sync now drops fetched messages older than policy.ageCutoffMillis before persisting (the same cutoff
the pruner uses), so sync and prune keep exactly the same set in both retention modes. Count/unlimited
modes have a null cutoff and are unchanged. The empty-folder wipe is keyed on the raw fetch (server
truth), so a folder holding only past-cutoff mail is left to the pruner rather than wiped.
MailPruner's KDoc now documents the sync alignment for both modes.
Closes#193

Make the latest-API-level emulator E2E (api36DebugAndroidTest, the
highest level in the E2E matrix and its Gradle Managed Device task) an
actually-run, required step:
- CLAUDE.md: preflight now runs api36DebugAndroidTest, and a change is
not done until that E2E runs and passes locally (not merely compiles).
The full multi-API matrix and the API 37 preview job stay CI's job.
- preflight skill: add the api36 E2E as the final step, note the
emulator/managed-device precondition, and replace the old
"don't run E2E locally" guidance so the two files agree.

State plainly that a change isn't complete without passing unit tests
and E2E/instrumented tests covering it, with no softening about
running the emulator matrix locally being optional.

Codify that a task/PR isn't complete without both passing unit tests
and E2E/instrumented tests covering the change. Writing and committing
the E2E/instrumented test is required; only running it against a
booted emulator locally stays optional, since CI's E2E matrix covers
that.

DiagnosticsCollector now includes one "<provider> (<authType>)" entry per account (the count is the
list size) in DebugReport.accounts, alongside the existing settings + recent-log capture. The provider
is a coarse bucket derived from the IMAP host (Gmail/Yahoo/iCloud/Outlook/AOL/Other) — never the raw
host or email — so no PII leaks; a custom domain buckets to "Other". Accounts are cached like settings
so crash reports (built on the crashing thread) include the last-known snapshot; accounts live in the
non-auth AccountDatabase, so reading them never blocks on the encrypted cache.
Recent device/app logs were already captured (RingLogBuffer) and serialize as the report's "logs".
Closes#235

Adds ReportPurgeWorker, deleting locally-stored crash/problem reports older than
30 days via new ReportStore.purgeOlderThan(cutoffMillis). Scheduled as a periodic
WorkManager job with a charging constraint (SyncScheduler.schedulePeriodicReportPurge,
enqueued at startup alongside sync/backfill/prune) so it never costs battery. Reports
are file-backed (no DB), so the worker needs no cache-lock gate.
Also discloses the auto-deletion: the problem-reports list and the submission review
screen state reports are deleted from the device after 1 month.
Tests: ReportStore.purgeOlderThan cutoff (boundary kept); ReportPurgeWorker computes a
~30-day cutoff and retries on failure.
Closes#239

Completes the crash-interrupted #192 WIP (app/build.gradle.kts already had a
jacocoTestReport task and toolVersion pin recovered onto build-192-jacoco):
- Move the JaCoCo tool version into gradle/libs.versions.toml instead of a
hardcoded string in app/build.gradle.kts, matching how every other plugin
version in this repo is sourced.
- Fix the generated-code exclusion list against the real compileDebugKotlin
output (verified by inspecting the compiled class tree): Room's
KSP-generated `_Impl` DAOs/database and the Compose compiler's per-file
ComposableSingletons holders are the only generated code that actually
lands in classDirectories, since Hilt/Dagger's generated Java and AGP's
BuildConfig/R/Manifest are compiled by a separate javac task this report
never reads. Drop the blanket `**/*$$*` exclude the WIP had — it was
silently discarding ~200 real classes' worth of coverage on Kotlin's own
`$$inlined$` synthetic classes (e.g. Flow.map { ... } transforms in the
repositories), which is hand-written logic, not generated boilerplate.
- Add Hilt_*/Dagger* prefix patterns so the (currently inert,
belt-and-suspenders) Hilt exclusions are actually correct if the
classDirectories scope ever changes.
- Add a minimal CI step to the existing unit-tests job that runs
jacocoTestReport and uploads the XML+HTML report as a build artifact.
No coverage threshold gate yet (a jacocoTestCoverageVerification rule is
a natural follow-up once there's a baseline).
- Document the new :app:jacocoTestReport task in CLAUDE.md.
Verified on JDK 21: fast gate (assembleDebug, testDebugUnitTest,
compileDebugAndroidTestKotlin, lintDebug, ktlintCheck, detekt) plus
jacocoTestReport all pass, from both a warm and a `clean` build. The
report shows real signal (30% instruction / 38% line coverage) with no
generated classes leaking in.

Give accounts a user-controlled order (issue #164). Every surface that
lists accounts -- the Settings list, the drawer account switcher, and the
compose account picker -- reads the same `ORDER BY sortOrder` query, so a
reorder in Settings is honored app-wide. In Settings a row can be
long-pressed and dragged to a new position; the order persists and
survives restart.
Data layer:
- AccountEntity gains `sortOrder` (@ColumnInfo defaultValue "0"); AccountDao
orders by it and adds insertAtEnd / reorder / nextSortOrder / setSortOrder,
the mutations wrapped in transactions.
- New accounts are appended (current max + 1) via insertAtEnd.
Migration (AccountDatabase v1 -> v2):
- ACCOUNT_MIGRATION_1_2 adds the column and backfills existing accounts by
their previous alphabetical (email) rank, so the already-shown order does
not shuffle on upgrade. Registered in AccountDatabaseModule; 2.json is
exported and AccountMigrationTest replays and validates it.
- AccountDataMigrator (the pre-#111 cache->account-db move) creates the
v2-shaped table and applies the same email-rank backfill, since
ACCOUNT_MIGRATION_1_2 does not run for that path.
UI:
- AccountReorderList drives long-press drag over a plain Column (no nested
lazy list inside the scrolling settings column, no extra dependency); the
pure reorder-index maths (commitDrag) is unit-tested.
