android: update the app from the server it syncs with (2727, M12 step 7)
Closes M12. The phone can now notice that its server has a newer build and install it, instead of the operator copying an APK to a device by hand. **A PackageInstaller session, not an install intent.** The obvious route — ACTION_VIEW on the APK — is exactly what on-device install heuristics are tuned against, and it is what produced the "bypassing Android security" warning on Minstrel (Scribe note 2437). It also never tells the OS that this app is the legitimate updater of its own package, and it returns nothing: a failed install is indistinguishable from someone dismissing the dialog. The session says who is doing what, and on Android 12+ declares no user action required — which, with UPDATE_PACKAGES_WITHOUT_USER_ACTION, removes the confirmation entirely on the UPDATE path. Only there: Android will not let an app quietly put a NEW package on a device, which is right. It also only applies when the new build carries the same signing key as the installed one, which is why signing had to land first. Two things from that research deliberately NOT done: `setRequestUpdateOwnership` was chased and turned out to be a red herring, and REQUEST_INSTALL_PACKAGES is not the differentiator either — Mihon declares it too. The mechanism was the whole difference. **The outcome comes back.** `commit` takes an IntentSender and the result lands at `UpdateReceiver`, so a failure can be shown rather than guessed at, and STATUS_PENDING_USER_ACTION is handled — that is the ordinary path below API 31 and still possible above it, since the OS is entitled to ask anyway. Someone declining is reported as no error at all: calling a deliberate choice a failure is how an app sounds broken when it is not. **The network work stays in Rust.** Two FFI additions — `clientUpdate` and `downloadClientUpdate` — because the device token lives in the core, and pulling it into Kotlin to make an HTTP call would spread the one secret this app holds across two languages for nothing. The core also owns the comparison, so the rule "version CODE decides, never the name" lives in the layer that has to get it right for every surface. The download is streamed to disk, not buffered: 55 MiB in memory on a phone is how an update gets killed halfway through. It lands in `update.apk.part` and is renamed only once size and sha256 both match, so an interrupted download can never be mistaken for a finished one. The digest is not a trust anchor — the signature is, and Android checks it — but it catches a truncated transfer before the installer is bothered with it. The advertised path is joined to the base URL this device is LINKED to rather than followed as given, so a server cannot point the download at a host nobody agreed to. **Updates are linked-only, and it says so.** An unlinked install has no update path, so it gets one sentence explaining where updates come from rather than a Check button that silently finds nothing — the same lesson as the desktop's unlink copy (issue 2110). And the "install unknown apps" grant is asked for BEFORE downloading, so nobody spends 55 MiB to be told no. Every Android API here was read out of `android-36/android.jar` with javap first, and the two new FFI methods out of freshly generated bindings, rather than recalled: `suspend fun clientUpdate(installedVersionCode: Long): ClientUpdate?` and `downloadClientUpdate(destPath: String)`. Also fixes `check-symbols.py`, which reported four false positives on `UpdateOutcome.Result` — its object-member index collected functions and properties but not nested TYPES, and a data class inside an object is an ordinary member. |

android: reminders that actually reach you (M12 step 6)
Reminders have been settable since the editor landed and have never once gone off. The board showed them overdue in red, which tells you what you already know by the time you are looking at the board. **AlarmManager, not WorkManager.** The background sync is right to be on WorkManager — nobody minds whether it runs at 3:05 or 3:19. A reminder minds very much. WorkManager's periodic floor is fifteen minutes and it batches into maintenance windows, so "remind me at 09:00" would routinely arrive at 09:14, which is not a reminder, it is a rebuke. **One alarm, not one per reminder.** Only the earliest future reminder is ever scheduled; when it fires, everything due is announced and the next is scheduled. A hundred reminders cost one alarm, and there is no incremental bookkeeping to drift — `Reminders.refresh` recomputes the whole picture from the store, and is called from everywhere anything could have changed: an edit, a foreground, a background sync, boot, and an app update. Boot and MY_PACKAGE_REPLACED both matter and both are easy to forget. Pending alarms survive neither, and this app updates by APK from its own server, so without that receiver a phone would silently stop reminding anyone of anything after a restart — the worst kind of failure, because nothing appears wrong. **Neither permission is treated as a prerequisite.** SCHEDULE_EXACT_ALARM, not USE_EXACT_ALARM: the latter is granted at install with no prompt and is reserved for apps whose whole purpose is an alarm clock or a calendar, which this is not. Refusing the former costs precision, not the feature — it falls back to an inexact alarm, because a reminder a few minutes late beats no reminder. POST_NOTIFICATIONS is asked for on the first launch where a reminder actually exists, never at launch on an empty board. Android gives an app essentially one chance at that dialog, and spending it before the person has any idea what this app would send them is spending it on nothing. For anyone who refuses, or who turns notifications off later in system settings, the Reminders view carries a standing notice with a button to the right screen — a feature that silently does nothing is worse than one that is plainly absent. **A first run adopts overdue reminders silently.** The storm case is linking a server and pulling months of history; a hundred notifications the moment someone signs in is a good way to have the feature turned off before it is ever useful. After that, a missed reminder is announced up to a day late — the web uses fifteen minutes because an open tab has been polling every forty-five seconds, but a phone can be switched off all night. Done and Snooze act from the shade without opening the app. The dedupe key is note id plus remind_at, the same one the web store uses, so snoozing produces a new occurrence rather than one already dealt with. Tapping a notification opens that note. The extra is CONSUMED when read: the Activity keeps the intent it was launched with, so without that, rotating the phone would replay it and reopen a note the person had already closed. `Reminders` split into scheduling policy and `ReminderNotification` rendering after detekt counted fourteen functions in one object — it was right, they answer different questions and change for different reasons. `ForegroundTransitions` moves to the ui package; the reminder notice needs it to re-read a permission the person may have just changed in a system screen this app cannot observe. Known gap, pre-existing and shared with every surface: `complete_reminder` in the core clears a reminder without advancing recurrence — its own comment says so. So tapping Done on a daily reminder ends it rather than moving it to tomorrow. Not changed here because it is core behaviour the desktop and web also have, but notifications make it much easier to hit, and it should be next. |

android: name all four permissions WorkManager adds, not one
The note added with the previous commit said RECEIVE_BOOT_COMPLETED arrives in the merged manifest via WorkManager. True, and incomplete — it brings four: RECEIVE_BOOT_COMPLETED, ACCESS_NETWORK_STATE, WAKE_LOCK and FOREGROUND_SERVICE. A comment whose whole job is "here is why the permission list has entries this file does not declare" fails at that job if it accounts for one of them. Each now says what it is for, checked against the built APK's merged manifest rather than the library's — which is the version a person actually sees. |

android: sync without being asked (M12 step 6)
Until now every sync was a button press. Pull-to-refresh made asking cheaper; it
did not stop the app needing to be asked, which on a phone means a note written
on the bus reaches the desktop whenever you next happen to open the app.
Three moments, and they are deliberately not the same job:
* **Coming to the front**, if the last sync is over five minutes old or there
is unsent work. Not on every foreground: stepping out to copy a link and
stepping back is not a request for fresh notes, and syncing on every app
switch spends someone's mobile data telling them what they are looking at.
* **Going away with unsent work** — handed to WorkManager rather than run
inline, because the process is about to stop being a priority and a sync
started there would be killed halfway. This is the one that matters most: it
is what gets a note off a phone that then goes into a pocket for the night.
* **Every fifteen minutes**, network-constrained. Fifteen is not a preference,
it is WorkManager's floor for periodic work; asking for less gets fifteen.
**An automatic sync must not raise an error banner.** Someone who pulled the
board down is owed an answer; someone who merely opened the app did not ask a
question, and answering it with a red banner about an unreachable server makes
their own notes look broken when nothing of theirs is. So `syncNow` and
`syncQuietly` differ in exactly one thing — whether failure is announced. The
quiet channel for a persistent problem is the drawer badge, from `has_pending`,
which does not care how the attempt was made.
**There is a switch, defaulting to on.** Linking a server IS the consent; a
person who paired a device and then had to find a second toggle before anything
moved would reasonably call that broken. It lives in SharedPreferences rather
than the store: everything else in sync state describes the PAIRING and must
survive a reinstall, while this describes how one handset behaves, and someone
turning it off on their phone is not asking their laptop to stop. The copy says
what "automatically" means in minutes and says that off is not off — a switch
next to a Disconnect button invites exactly that misreading.
The schedule is DECLARED as a function of (linked, switch) in a LaunchedEffect
rather than toggled from the places that change them. There are four routes to
"should not be syncing on its own" and a call at each is four chances to leave a
phone quietly syncing after it was told to stop.
`ON_START`/`ON_STOP`, not resume/pause — the same choice the editor's save-on-
leave makes, because pause fires for anything covering the window and a sync per
notification-shade pull is not automatic sync, it is a stutter.
RECEIVE_BOOT_COMPLETED now appears in the merged manifest. WorkManager
contributes it so the schedule survives a restart; commented in AndroidManifest
because it shows in the app's permission list and nothing else in that file
would explain it.
Two things read from artifacts rather than recalled, both of which memory would
have got wrong: `work-runtime-ktx` is an empty 6 KB stub as of 2.11 with
`CoroutineWorker` and `PeriodicWorkRequestBuilder` moved into `work-runtime`, so
the dependency is on the latter alone; and `Switch` is not experimental in
material3 1.4.0, so no `@OptIn` — an unnecessary one is itself a warning.
Also adds `android/tools/check-strings.py`, after this change added three
strings: `R` is generated, so `R.string.typo` type-checks whether or not the
string exists. It catches a missing name, `stringResource` on a plural or the
reverse, and a format taking more arguments than the call passes. Verified
against a tree with one of each fault — its first version counted Kotlin's
trailing commas as arguments and called three correct sites broken, which is the
failure that teaches you to ignore a tool.
Two comments in this change were wrong when written and are corrected here
rather than left: the flag check in SyncWorker does NOT avoid opening the store,
because Application.onCreate has already run by the time any Worker starts.

android: connect a server from the phone (M12 step 6)
The plumbing has been bound since step 4 — probe, link by password or token, unlink, sync — with nothing on top of it. Until this commit the phone was a good standalone notes app that could not be the SAME notes as the desktop, which is the point of the project. Structurally a port of the desktop's SyncView.vue: same probe-then-link order, same copy wherever the copy was already right. The two surfaces pair with the same servers, and a difference in wording here would read as a difference in behaviour. BEING UNLINKED IS NOT A PROBLEM, and the screen is written around that. It leads with "Working offline on this device" and says what connecting would ADD. A local-first app that frames its resting state as unfinished setup is lying about what it is. The drawer badge follows the same rule: it says nothing at all when unlinked, rather than "Off". Probe before credentials. A typo that reaches a stranger's server should cost a round trip, not a password — so the address is checked first, what answered is shown (name, version, compatibility), and only then does a sign-in form appear. An incompatible server never gets one; the core would refuse the link anyway, and collecting a password to throw away is worse than not asking. CLEARTEXT IS NOW PERMITTED, deliberately and not silently. Android blocks plain http from API 28, and the core explicitly supports a self-hosted server on a LAN — `http://192.168.1.10:8000` is a case it has a test for. The platform default would make this app unusable for exactly the people it is built for, with a transport error they could do nothing about. A network-security-config would be tighter in principle but matches domains and IP literals, not CIDR ranges, so it cannot express "my own network". The other half of the trade is a warning that appears the moment a probed address starts with http:// and BEFORE any credential field: anyone on the same network can read your password and your notes. Credentials never enter the view model. The address, email and device name are `rememberSaveable` so a rotation doesn't cost a retype; the password and the token are plain `remember` on purpose — rememberSaveable persists into the instance-state bundle, and a secret has no business being written there to save four seconds of typing. They reach the core as a `Credentials` sealed type and die with the composable. That sealed type also fixed a bug detekt surfaced by complaining about a six-parameter function: `link_with_token` takes NO device name (the token was already minted against a named device in the web app), so the flat argument list meant the form collected one in token mode and silently dropped it. The field now exists only on the password path. Threading, which differs by call and is easy to get wrong in one direction: probe / linkWithPassword / linkWithToken / unlink / syncNow are Rust async through uniffi, so Kotlin sees suspend functions already driven by tokio and awaits them directly — wrapping them in Dispatchers.IO would park a thread to wait on something that never blocks one. syncStatus and hasPending are ordinary blocking FFI into SQLite and do need it. A sync that changed anything tells the board to reload, because a pull can have rewritten every note it is holding. Wired explicitly at the one place that owns both view models rather than through a shared event bus. A no-op sync deliberately does not, so the board never flashes its loading state for nothing. Sync results are kept RAW in state and turned into sentences in the UI, where stringResource is in scope — the same split Time.kt draws for timestamps. The summary counts what MOVED; batches, pages, noop and cursor are all real numbers and none of them answer "are my notes in step". Rejections are surfaced rather than swallowed: only a person can resolve them. So is a revoke that didn't land — someone disconnecting to retire a phone has to be told a live credential is still out there, and has to still find it when they come back to check, so it is a persistent notice and not a toast. Also here: `Panel`/`Notice` extracted as shared tinted chrome, drawn from the same note palette the cards use rather than Material's errorContainer, so a warning is the same yellow a note can be. `PlainTextField` gained a visual transformation for the password field. `formatReminder` became `formatInstant` now that "last synced" reads it too. Verified locally per ci-requirements.md: ktlint and detekt clean in ci-rust-android:1.97, uniffi bindings generated from a host build and read to confirm ULong on the summary counters, `Compatibility.Ok`/`RevokeOutcome. Unsupported` being objects, and all five sync calls being suspend. Every R.string/R.plurals reference cross-checked for existence, kind and format arity. A symbol-resolution pass over the whole package caught a composable a bad edit had deleted — ktlint and detekt both parse without resolving, so neither could see it. Not done: no automatic sync. The desktop is manual-only too, so this is parity rather than a gap, but pull-to-refresh on the board is the obvious phone-native follow-up. Worth an operator decision, not changed here: allowBackup is still true, so Android's cloud backup now includes a device token as well as the notes. Good for restoring to a new phone, and a wider blast radius than before this commit. Scribe #2777 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

android: a Kotlin/Compose app that drives the Rust core (M12 step 5)
The skeleton, and the lane that builds it. Gradle invokes cargo-ndk to
cross-compile thoughtsync-ffi for four ABIs, generates the Kotlin bindings from
the resulting .so, and packages both.
BUILT ON MINSTREL'S TOOLCHAIN, not a fresh guess. Gradle 9.1.0 / AGP 9.0.1 /
Kotlin 2.3.21 on JDK 25 is the combination already proven in this family on
ci-android, including the JDK 22+ native-access opt-in the launcher JVM needs
and the artifact-upload action pinned by SHA (issues 2255 / 2270). It also
independently confirms the JDK 25 call made on ci-rust-android in step 3.
Gradle wiring worth noting:
* ExecOperations, not project.exec — the latter was REMOVED in Gradle 9, and
touching `project` at execution time is also what breaks the configuration
cache this build enables.
* The cargo task's inputs are the Rust SOURCES, not the workspace directory.
Declaring the directory would make Gradle hash target/, which is gigabytes.
* Bindings are generated with `--library` against the built .so, so they can
never describe a different version of the Rust than the one being packaged.
* cargo runs --locked, so an Android build cannot silently re-resolve the
lockfile the desktop lanes are gated on.
JNA is a real dependency, with the @aar classifier. The plain jar builds fine
and fails at runtime with UnsatisfiedLinkError, which is the worst way to learn
it. R8 keep rules for JNA and the bindings are in for the same reason — that
failure would otherwise appear only in a minified release.
The UI is a working board, not a debug screen: capture field, note list, empty
state, error banner, and an honest failure screen for a store that won't open.
Rules 23/24 — a surface ships at quality from the first commit. Capture uses the
IME action key because the north star is a thought captured in under a second,
and leaves the title empty so the core derives it from the first body line.
Every core call runs on Dispatchers.IO: they are blocking FFI into synchronous
SQLite, and running them on the main thread is exactly the jank going native was
meant to avoid.
The launcher icon reuses frontend/public/icon-maskable-512.png as an adaptive
foreground on the brand #F5C518 — the same asset and colour the web app already
ships, so the three surfaces wear one face.
No signing config. A release keystore that has passed through an agent session
or shell history is compromised by construction (task 2136); it has to be
generated by the operator and reach CI only as a secret. CI builds debug.
CI can only prove this BUILDS — a Linux runner cannot execute an APK, so feel
and on-device correctness remain an operator pass on an emulator.
Scribe #2739.
