A message with several attachments used to render every AttachmentRow
stacked vertically, pushing the message body arbitrarily far down. Now
only the first attachment shows by default; when there is more than one,
the extras collapse behind a "See x more attachments" control that
expands and collapses with an animated, rotating chevron. A single
attachment renders exactly as before (no accordion).
The count uses a plurals resource (quantity one/other) so it reads
"See 1 more attachment" / "See 2 more attachments" correctly. The toggle
is one clickable Role.Button whose label and chevron contentDescription
expose the expanded state to screen readers. Download/open behavior of
each row is unchanged.

Recipient autocomplete's READ_CONTACTS permission was requested lazily on
every compose-screen open (a LaunchedEffect(Unit)), re-prompting users who
had declined. Move the request to a dedicated, skippable onboarding step and
add a Settings entry to turn it on later, each with an in-context rationale.
- #127: new skippable ONBOARDING_CONTACTS step (mirrors the battery step),
requested once. ComposeScreen no longer prompts; it only reads the current
grant on resume, so a grant made later (e.g. from Settings) still takes
effect the next time compose opens.
- #128: the onboarding step and the Settings request show a short rationale
(contacts are used only for on-device autocomplete, never uploaded) and
handle shouldShowRequestPermissionRationale so a re-request explains itself.
docs/play-permissions.md updated to match.
- #129: Settings -> Contacts -> Recipient autocomplete reflects on / off /
blocked-in-settings; requests in-app when grantable, deep-links to the app's
system settings when permanently denied.
Graceful degradation is preserved: ContactsRepository.search still runCatch-es,
ComposeViewModel.searchContacts() still guards on contactsAllowed, and the
suggestion list still renders only when non-empty.
Adds a pure ContactPermissionDecision (JVM unit-tested), extends the onboarding
view-model tests, and adds Compose UI tests for the onboarding step
(skip / grant / deny / rationale) and the Settings row states.

The unified inbox query (WHERE folder = ?, no accountId) has no folder-leading
index, so it scans in timestamp order and materializes the whole unified inbox
(~4k rows at a 20k cache) into memory on every emission. Apply Paging 3 to the
unified browse path so query, mapping, and recomposition cost scale with the
visible window, not the total cache.
- MessageDao.pagingUnifiedFolderSummaries: a PagingSource over the folder's
synced rows (inInbox = 1); unified search keeps the whole-folder query so it
can still surface transient server-search hits.
- MailRepository.pagedUnifiedFolderMessages: a Pager (pageSize 40, initialLoad
120, no placeholders) mapping summaries to domain.
- MailboxViewModel.pagedMessages: paged while browsing the unified inbox, else
empty; the messages list flow stays empty in that state so the whole cache is
never materialized. Selection captures each row's accountId at tap time, so
"Move" still resolves the selection's account without an in-memory list.
- MailboxScreen renders the unified browse list via collectAsLazyPagingItems;
per-account and search views render the flat list unchanged (issue #86 stays
flat).
Profiling (docs/perf/issue-124-unified-inbox-paging.md) on an api29 emulator:
current whole-inbox first-emit ~24.6 ms at a 20k cache vs. the paged first page
~6.8 ms and flat regardless of cache size (~3.6x). EXPLAIN QUERY PLAN shows the
paged query still stops early on the existing timestamp index, so no
(folder, ...) index and no schema migration are added.

Device upgrade testing surfaced a crash: on a cache last written before
v13, account_settings has 4 columns (accountId, signature,
signatureEnabled, notificationsEnabled) but the destination table has 6
(retentionCount/retentionMonths were added at v13). The migrator ran
`INSERT OR IGNORE INTO account_settings SELECT * FROM cache...`, which
supplied 4 values for 6 columns and threw SQLiteException — and because
the done-flag is only set after a successful copy, every launch re-ran
and re-crashed (crash loop).
AccountDataMigrator now copies each table by the column names present in
BOTH the freshly-created destination and the (possibly older) source, so
columns the source lacks take the destination's defaults instead of
overflowing the value list. Verified on-device: the upgrade migrates a
pre-v13 install cleanly and the account stays signed in (sync/backfill
workers run). Regression test seeds a v12 cache and asserts the copy.

Two on-device assertion failures (green on JVM compile, red on the
emulator):
- migratorDdlMatchesExportedAccountDatabaseSchema built its expected DDL
by substituting the schema's `${TABLE_NAME}` placeholder with a
backtick-wrapped name, but the exported createSql already wraps the
placeholder in backticks — producing a double-backticked identifier
that never matched the (correct, single-backticked) migrator DDL.
Substitute the bare name so the guard compares like-for-like.
- movesEveryAccountTableOutOfAPlaintextCache asserted signatureEnabled
was false, but the seed row sets it to 1 (true). Assert the seeded
values for both booleans so a true and a false each round-trip.
The production migrator DDL and drop logic were already correct; only
the tests were wrong.

`@Test fun x() = runBlocking { ... }` whose block ends in `.apply { }`
returns the DB (non-Unit), so JUnit4 rejects the whole class at runtime
with InvalidTestClassError ("method should be void") — which compiles
fine locally but fails every E2E job on the emulator. Use
`runBlocking<Unit>` (the existing DatabaseEncryptionTest idiom) so the
methods are void while keeping the expression body ktlint expects.

Accounts, credentials, per-account settings and signatures lived in the
same libremail.db that SQLCipher encrypts under the auth-bound passphrase
when app-lock + encrypted-cache are on. A genuine key invalidation
(biometric re-enrollment or lock removal/re-add) made that file
undecryptable, and the "clear + re-sync" recovery wiped the accounts and
stored credentials along with the mail cache, dropping the user into
onboarding (issue #111).
Move those four tables into a new plaintext AccountDatabase
(libremail-accounts.db) that is never bound to the auth key. Credentials
stay AES-GCM sealed at the column level by the surviving non-auth
KeystoreCrypto master key, so the only secret never touches disk in the
clear. A cache-key invalidation now wipes only libremail.db; the user
stays signed in.
- AccountDatabase (v1) + AccountDatabaseModule; the cache DB drops to v15
via MIGRATION_14_15. DAOs are unchanged and re-provided from the new DB,
so no injection site changes.
- AccountDataMigrator performs the one-time cross-DB copy at startup,
before Room opens either database. It attaches the cache (with its
resolved passphrase, so an encrypted source is handled) and copies with
INSERT OR IGNORE. It is crash-safe and idempotent: the source is dropped
only by MIGRATION_14_15 after the copy, a re-run never duplicates or
overwrites, and it runs after the clear-pending wipe so an unrecoverable
cache degrades to "nothing to move" instead of blocking.
- Exported schemas for both databases; MigrationTest asserts the account
rows/backfills survive to v14 then are dropped at v15, plus a dedicated
14->15 test. AccountDataMigratorTest covers the plaintext + encrypted
copy, idempotency, a DDL-vs-Room drift guard, and end-to-end survival of
a simulated cache wipe.

The mailbox list observed the entire `messages` table (observeSummaries, no
WHERE/LIMIT), mapped every cached row to a domain Message, and filtered down to
the visible account+folder in MailboxViewModel — so its cost scaled with the
whole cache and re-ran on every write to `messages` (IDLE delivery, a flag
toggle, a backfill page, any folder sync). On a 20k-row cache that is ~125 ms of
work per unrelated write.
Push the account/folder filter into SQL (observeFolderSummaries /
observeUnifiedFolderSummaries, exposed via observeFolderMessages /
observeUnifiedFolderMessages) and flatMapLatest the ViewModel over the selected
account+folder. The only remaining client-side pass separates the normal list
from an active search over the small folder-scoped set.
Validated on an emulator against 1k/5k/20k-row caches (docs/perf/issue-86-
profiling.md): the account-scoped query is ~1.5 ms flat (~80x faster at 20k) and
is already served by the existing (accountId, folder, uid) index — so NO
composite index and NO schema migration are added. The ticket's proposed
(accountId, folder, inInbox, timestampMillis) index changes timing only within
noise and isn't even preferred by SQLite's planner. The unified "All inboxes"
view stays an O(N) folder scan (still 5.6x better) and is a follow-up for paging;
IMAP latency on folder open is a separate, unmeasured concern.
Closes#86

parentOf() re-inferred the IMAP hierarchy separator from each folder's name,
relying on an unenforced invariant (displayName == fullName.substringAfterLast(
separator)) established three layers from where ImapClient reads the
authoritative JavaMail folder.separator and then discards it.
Carry that separator through FetchedFolder -> FolderEntity -> Folder and split a
folder's parent on it. Fall back to the old name inference only for legacy rows
whose delimiter is null, until the next folder refresh (delete-then-insert)
backfills the real value.
Adds a nullable folders.hierarchyDelimiter column via a Room v14 -> v15 migration
with the exported v15 schema, and registers MIGRATION_14_15 in DatabaseModule so
existing v14 installs actually upgrade (provideDatabase configures no destructive
fallback, so an unregistered migration would crash every upgrading user).
Tests: JVM unit tests for parentOf() (persisted vs. null delimiter, incl. the
case where inference cannot locate the parent) and the FetchedFolder->entity
round-trip; an instrumented v14->v15 migration test plus the chain-replay
assertion.

Behavior-preserving cleanup of the app-lock UI plumbing:
- SettingsScreen: replace the app's only Toast with the canonical
SnackbarHostState + Scaffold(snackbarHost) + consume pattern for the
app-lock rejection message (matches MailboxScreen); the ViewModel keeps
the @StringRes id, resolved via LocalResources at the display boundary.
- AppLockGateHost: replace the hand-rolled DisposableEffect +
LifecycleEventObserver with LifecycleEventEffect, and the ContextWrapper
findFragmentActivity() walk with LocalActivity; remember the derived
activity and the authenticate lambda.
- AppLockManager: delete the dead availability() API and the four-value
AppLockAvailability enum (no production caller; the
BIOMETRIC_STRONG or DEVICE_CREDENTIAL canAuthenticate combo is
unsupported on minSdk 29). Keep isDeviceSecure() and AUTHENTICATORS.
- AppLockViewModel: derive the gated uiState from the injected gate via a
single publish() helper instead of hand-mirroring gate.state at each
auth site; the transient Checking cover and app-lock-off unlocked states
stay explicit (settings/lifecycle-driven, not session-gate-driven).
Extend SettingsScreenTest with a Compose test for the rejection snackbar
(now visible to Compose semantics) and drop availability() from its fake.

Adds a live unread-count signal shared by two navigation-drawer indicators:
- #83: each folder row shows a trailing unread-count badge (capped at
"99+"), hidden when zero. Screen readers announce the exact count via a
plurals content description.
- #84: accounts with unread mail render their email in bold in the drawer
account switcher and the mailbox account-filter chips.
Both derive from one efficient Room aggregate, MessageDao.observeUnreadCounts():
a COUNT(*) ... GROUP BY accountId, folder over folder-synced rows
(inInbox = 1 AND isRead = 0) that pulls no message rows into memory. Its
GROUP BY is served by the existing (accountId, folder, uid) index, so no
schema change or migration is needed. MailboxViewModel derives
folderUnreadCounts (drawer account, per folder) and accountsWithUnread
(any folder) from the one shared flow.
Unread scope is folder-synced mail in any folder, kept consistent across
both features: an account reads as bold exactly when one of its folders
shows a badge.

Periodic sync, backfill, and prune were enqueued with
ExistingPeriodicWorkPolicy.KEEP, so a newer app version's interval or
constraint change never reached already-installed devices: KEEP pins the job
to the spec from whichever version first scheduled it.
Switch the three periodic schedulers to UPDATE (WorkManager 2.8+; 2.11.2 in
use), which re-applies the current spec on each app-start re-enqueue while
preserving the running period's progress. An unchanged spec is effectively a
no-op, so this never resets the schedule on launch the way REPLACE (cancel +
re-enqueue) would. The one-shot kicks (syncNow/backfillNow/pruneNow) keep
their existing policies -- they are a separate concern from #96.
SyncScheduler now injects Provider<WorkManager> (via a new WorkManagerModule)
instead of calling the WorkManager.getInstance() static directly, so the
policy is unit-testable with MockK; the Provider keeps resolution lazy to
preserve the previous initialization timing.

Closes the two test gaps from PR #54's review (issue #64).
1. The single production link between a server LIST response and the folder
feature -- FetchedFolder.toEntity deriving role (FolderRole.roleOf) and
specialUse (FolderRole.isServerSpecial) from IMAP attributes, plus
FolderEntity.toDomain's specialUse pass-through -- had zero coverage; every
listFolders stub returned emptyList and other tests hand-set specialUse.
Adds FolderMapperTest pinning each RFC 6154 attribute to its expected
(role, specialUse): \Sent/\Drafts/\Junk/\Trash/\Archive drive a role and
mark the folder special, while \All/\Flagged mark it special but drive no
role of their own. Adds a MailRepositoryImplTest refreshFolders case that
slot-captures replaceForAccount and asserts persisted specialUse == [true,
false], and extends the observeFolders test to assert the toDomain leg.
2. baseLabelsOf's doc comment claimed it builds labels "the way the drawer
does", but it is a hand-copied literal stand-in for folderDisplayLabel
(which is @Composable and unreachable from a JVM test). Rewords it to state
it is an independent literal fixture that pins the de-dup logic, not the
role-to-wording mapping, and gives FolderDrawerTest an ARCHIVE fixture whose
server name ("All Mail") differs from its friendly label so it can actually
discriminate role-to-label drift.
The mapping itself was correct, only uncovered -- no production change; the
attribute-to-role table refactor is #65.

Two code-review-derived backfill-correctness bugs (from the PR #46
review). Both govern where MailBackfiller stops and resumes paging a
folder, so they are fixed together.
(MIN(timestampMillis)), but paging descends by UID. One high-UID
message with an old Date header (moved/imported mail) dragged the
cached minimum below the cutoff and marked the folder complete while
lower-UID within-retention messages were still unfetched — a silent,
permanent gap (completion is sticky). The age floor is now decided from
each page actually fetched: only a page ENTIRELY older than the cutoff
(or folder exhaustion) ends paging, and such a prune-fodder page is not
persisted. The count floor keeps its cheap cache check — it orders by
UID like paging, so inversions can't bite it. oldestSyncedTimestamp had
no remaining caller and is removed.
migrated before the uid column existed, or a UIDFolder.getUID -1
fetch); fetchOlderThan treats beforeUid <= 1 as "nothing older", so the
folder was falsely marked fully backfilled. lowestSyncedUid now ignores
uid <= 0 rows (matching MailSyncer's minWindowUid guard), a stale
persisted boundary <= 0 is discarded on resume, and the per-page
descent takes min over positive UIDs only. A page of entirely
unresolved UIDs stalls the folder — it stays incomplete (a future
scheduled run retries) but reports no immediate more-work, so
BackfillWorker's slice-chaining loop can't busy-spin on it.
Together: #95 guarantees paging always descends with a real positive
UID boundary, and #94 makes the stop decision independent of cached
aggregates, so a placeholder or old-Dated row can no longer end
backfill early through either path. Completion stays sticky and is
declared only on positive evidence, preserving the #12/#13
backfill/pruner non-interference.
Tests (JVM, GreenMail + the existing in-memory DAO-fake harness; all
four fail against the pre-fix code): a high-UID/old-Date message must
not gap within-retention history (#94); an entirely-old page ends
paging without persisting prune-fodder (#94); a uid=0 row must not
poison the boundary (#95); a page of unresolvable UIDs stalls instead
of falsely completing (#95). MessageDaoRetentionTest pins the uid > 0
SQL guard against real SQLite and drops the removed oldestSyncedTimestamp
probe.

Three display bugs from the PR #54 code review, all in the shared
label-resolution/presentation path:
- #59: resolveDrawerLabels was wired only into the drawer, so the
move-to picker and the app-bar title still rendered the bare
folderDisplayLabel — two identical "Drafts" rows in the picker could
move mail to different folders. Both surfaces now consume the same
resolution via a shared resolvedFolderLabels helper; picker rows
resolve against the unfiltered target list so a row keeps its
disambiguation even when its colliding twin is filtered out.
- #60: two top-level folders sharing a role-derived base label (e.g.
"Sent" and "Sent Items" both classifying SENT on servers without
SPECIAL-USE) fell through to the full-path safety net as a
self-referential "Sent [Sent]". Colliding top-level user folders now
tie-break on the display name: the folder actually named like the
base keeps it, the others show their real server name. Corrected the
resolver KDoc's overclaimed uniqueness sketch.
- #61: the drawer derived the de-dup provider suffix from drawerAccount,
which updates before the lagging folders StateFlow during an account
switch, so stale Gmail folders briefly rendered as "Drafts - Outlook".
The suffix now derives from the rendered folder list's own accountId
(providerLabelFor), keeping a stale list under its own account's brand.
Tests: FolderLabelsTest covers the role tie-break and providerLabelFor;
MailboxViewModelTest pins the switch gap with Turbine; MailboxScreenTest
drives the disambiguated move picker (moving via "Drafts - Gmail" lands
in [Gmail]/Drafts) and the app-bar title; FolderDrawerTest renders the
transient switch frame.

Closes the gap where app/schemas was exported but never validated (#63):
- androidx.room:room-testing (androidTest) + ship the exported schemas as
androidTest assets so MigrationTestHelper can build old-version databases.
- MigrationTest: 11->12 asserts folders.specialUse arrives defaulting to 0
with existing rows intact; a chain-integrity test requires exactly one
migration per version step up to the newest exported schema; a full
v7->latest replay validates every step against its exported JSON and
asserts seeded v7 data and each migration's backfills survive. The
migration list is discovered from Migrations.kt and the target version
from the exported schemas, so a future migration is covered by just
committing its schema JSON.
- Pin kotlinx-serialization to 1.8.1 via its BOM: androidx.savedstate pins
1.7.3 transitively (shared with androidTest by AGP 9 consistent
resolution), and Room 2.8's schema-bundle serializers need >= 1.8.0 or
MigrationTestHelper throws AbstractMethodError parsing the schema JSON.
Identical to the pin already proven on the feat-fetch-all-retention
branch, so the two merge cleanly in either order.

The multi-select contextual action bar buried Archive, Spam, Move,
Select all, and the single-selection Reply/Reply All/Forward behind one
MoreVert dropdown; only Close and Delete were direct. Promote the
common actions to direct IconButtons, matching the reader app bar's
icons-not-menus pattern: Archive (Done glyph - material-icons-core has
no archive icon, so this leans on the "done = archive" mail idiom),
Spam (Warning), and Delete, each with a contentDescription for
accessibility.
The overflow keeps only the long tail: Move (no usable core glyph, per
the ticket it stays text-labeled), Select all, and the
single-selection reply actions. All conditional visibility is
preserved: Archive/Spam still hide while viewing their own role
folder, Move still requires a single-account selection, and the reply
actions still require exactly one selected message. Four 48dp actions
plus Close still fit a 320dp-wide bar; the count title just truncates
earlier.
UI tests: the direct Archive icon archives without opening the
overflow, the direct Spam icon still confirms before reporting, the
Archive icon hides inside the archive folder, and the overflow test
now keys on Select all instead of the promoted Archive.

The Cc and Bcc fields now start collapsed into small left-aligned link
buttons under the To box, freeing about two field heights of vertical
space for the message body. Tapping a link expands it into the regular
input field and focuses it; a field also expands on its own when it
already carries recipients (reply-all/mailto prefill, resumed drafts)
and never re-collapses once shown, so it cannot vanish mid-edit. The
expansion state lives in the UI via rememberSaveable and survives
rotation. Moving the Bcc field also gives it the medium shape every
sibling field already had.

Tapping a new-mail notification only brought the app to the foreground:
the content PendingIntent was a bare launch intent shared by every
notification, and nothing on the activity side handled a message target.
Per-message notifications now carry an explicit open-message intent —
action + id extra + a per-message data URI, so each message keeps its
own PendingIntent under filterEquals instead of all collapsing onto one
FLAG_UPDATE_CURRENT entry. MainActivity parses the id on fresh launch
and in onNewIntent and hands it to the NavHost as pending state (the
pendingCompose handoff pattern) to navigate to the reader. The group
summary keeps the plain open-the-app intent.

The androidTest compile failed ONLY in CI with "Unresolved reference 'observeAll'"

same file resolved, the identical observeAll().first().map{}.toSet() in
LibreMailDatabaseTest compiled fine in the same unit, and the file compiled cleanly
locally (even `clean --no-build-cache`). That points to a Kotlin incremental-compilation

The drawer rendered every standard-role folder with a generic friendly
name (e.g. "Drafts") and discarded the server name, so a Gmail account
with both a provider built-in folder and a same-named user folder showed
two identical entries (Drafts, Archive, Spam).
De-duplicate labels provider-agnostically: when 2+ folders would render
the same name, the provider's built-in special folder (identified by RFC
6154 SPECIAL-USE flags, now persisted on the folder cache) gets the
provider name appended ("Archive - Gmail"), a nested user folder gets its
parent location ("Reports (Work)"), and a top-level user folder keeps its
plain name. Only triggers on a real collision, so stock accounts are
unchanged.
Adds a `specialUse` column to the folders table (Room v11 -> v12).

The MailPruner/MailBackfiller unit tests mock the DAO, so the queries that
actually define the device-only retention floor were never exercised against a
real database: the newest-N-by-(timestampMillis, uid) prune selection, the
strict age cutoff, the windowed reconcile that spares backfilled history, and
the lowest-uid / count / oldest floor probes the backfiller stops on.
Add an instrumented MessageDao test on an in-memory Room DB covering all of
them, including the timestamp/uid tie-break direction (a flipped ORDER BY would
locally delete the user's newest mail) and inInbox/folder/account scoping.
This closes the disjoint-sets safety argument at the SQL-boundary level, not
just the orchestration level. Verified on the API 37 emulator (5/5).

MessageDao.observeAll() ran `SELECT * FROM messages` and returned full
MessageEntity rows — including the potentially large body/isHtml columns —
for every cached message at once. Dragging big HTML bodies through SQLite's
shared ~2 MB CursorWindow overflowed it once enough bodies were cached,
crashing with "Couldn't read row N from CursorWindow" (#51).
Replace it with observeSummaries(), a body-less column projection into a new
lightweight MessageSummary POJO. The list never renders or searches the body,
and the reader already loads it lazily per-message via getById when a message
is opened, so nothing else needs it.
Add a regression test that reads back rows whose bodies exceed the window.

locating the boundary by binary search over message numbers (O(log n) tiny
UID fetches, memory bounded to one batch).
- MailBackfiller + BackfillWorker page each synced folder newest→oldest,
persisting a per-folder boundary in a new backfill_progress table so a run
interrupted by process death / network loss resumes exactly where it stopped.
Runs off the sync mutex, so foreground sync / pull-to-refresh stay responsive.
- MailSyncer now reconciles server deletions only within the recent UID window
(deleteSyncedInWindowNotIn) instead of wiping everything outside the recent
50, so backfilled history survives each foreground sync. A materialized
messages.uid column powers the windowed reconcile and backfill boundary.
- Body/attachment prefetch still honours FetchPolicy (headers first).
- Per-account count/age overrides (nullable) with a global default; 0 = keep
everything (the default, matching #12).
- MailPruner + PruneWorker delete local rows beyond the limit (cascading
attachment rows + on-disk cache), never issuing a server delete. Deletes are
chunked under SQLite's 999-parameter limit.
- Precedence with backfill: backfill pauses (does not complete) at the
retention floor and both jobs share a maintenance mutex, so they never
contend; foreground fetch is also capped by the count so it can't re-download
what pruning just trimmed.
- Settings UI for the global default and per-account override, with copy making
clear it is device-only, not the server.
Room schema v9→v10 (migration + exported schema + MigrationTestHelper test).
GreenMail tests prove the backfill caches >50 and resumes after interruption;
pruning tests cover count/age limits and never touch the server.

Add a guided, F-Droid-safe onboarding step and an Advanced Settings recovery
row that let users move LibreMail to "Unrestricted" battery usage, so IMAP
IDLE push (IdleService) and periodic WorkManager sync aren't throttled or
killed by Doze. Deep-links to the system app-details screen rather than the
restricted REQUEST_IGNORE_BATTERY_OPTIMIZATIONS dialog, so it needs no new
permission and is safe on Play (#17) and F-Droid (#16).
- BatteryPromptDecision: pure, unit-tested gate (supported && !unrestricted && !handled)
- BatteryOptimizationManager: reads isIgnoringBatteryOptimizations, builds the deep-link intent
- Onboarding step shown after the first account is added; skipped when already
unrestricted or already handled; re-checks status on resume
- Advanced Settings row shows current status and re-opens the system screen
- battery_prompt_handled flag persisted in the settings DataStore (kept out of AppSettings)
- Unit tests for the decision + view model; Espresso E2E for the step
Closes#49
