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.

Inline images in rich HTML emails (embedded via Content-ID and
<img src="cid:...">, e.g. USPS Informed Delivery digests) were listed
under Attachments with a download button and never rendered in the body.
Two bugs combined; both are fixed here.
1. Misclassification: ImapClient classified any part with a filename as
an attachment, sweeping inline images (which carry a filename AND a
Content-ID under Content-Disposition: inline) into the list. A part is
now a downloadable attachment only when its disposition is attachment,
or it has a filename but no Content-ID; an inline image is collected
separately and excluded from the displayed list (AttachmentDao filters
contentId IS NULL). The Content-ID is read via MimePart.getContentID()
so it resolves from IMAP BODYSTRUCTURE rather than a per-part header
fetch that Angus leaves unpopulated.
2. No rendering path: HtmlBody's WebViewClient now overrides
shouldInterceptRequest to resolve cid:<id> to the matching part's
bytes (backing the CSP's existing cid: allowance). Content-ID is
threaded end-to-end through AttachmentPart, Attachment,
AttachmentEntity, and MailRepository.inlineImages(); ReaderViewModel
surfaces the cid->bytes map to the WebView.
Schema: adds attachments.contentId (v16 -> v17, MIGRATION_16_17).
Tests: MIME-part classification (inline+cid excluded, real/disposition/
filename-only kept), a GreenMail multipart/related round-trip, the
cid->bytes resolver, repository inlineImages(), the DAO display filter,
and the v16->v17 migration.
Closes#133

Wire ktlint-gradle 14.2.0 and detekt 2.0.0-alpha.5 (the only detekt line
with Gradle 9 support) through the version catalog.
- .editorconfig: official Kotlin style, 120-col limit, @Composable exempt
from function-naming.
- config/detekt/detekt.yml: slim overrides on detekt's defaults —
@Composable exemptions for the OOP-era metrics, sane ReturnCount /
ThrowsCount / TooManyFunctions thresholds, and TooGenericExceptionCaught
off at the resilient network/push boundaries (which now log).
Findings fixed in code (behaviour-preserving; 81 unit tests still pass):
- SwallowedException: SendWorker / IdleService now log the caught exception.
- roleOf (Folder) and extractBody (ImapClient) split into named helpers.
- MailSyncer: hoisted a 4-condition `if` into a named val.
- TopDest extracted to its own file; ~14 magic numbers -> named constants.
The remainder is the ktlint auto-format across the module.

Add a long-press contextual action bar to the mailbox: Archive, Delete,
Spam, Move, Select All, and (single-selection only) Reply, Reply All, and
Forward. Reply All/Spam/Delete are confirmed first; deleting from Trash or
Spam warns that it is permanent.
- Delete moves to Trash and Spam moves to the Spam folder; only deletes
already in Trash/Spam do a permanent IMAP expunge. Archive/Spam/Move
resolve the destination per account so the unified inbox works.
- Reply/Reply All/Forward force a fresh server fetch of the original
(recipients + body via BODY.PEEK), build a quoted draft, and open compose;
a spinner shows during the fetch and they error via snackbar if offline.
Add a top-level "Message downloading" setting (Always fetch all / Fetch all
on Wi-Fi / Always on-demand; default Always) that aggressively pre-caches
full bodies and all attachment bytes during sync (outside the sync lock,
without marking mail read), into a persistent per-part attachment cache so
messages and attachments open instantly and offline.
Show an "available offline" mark on cached list rows and a per-attachment
"downloaded" check in the reader.
Extract a Syncer interface (MailSyncer implements it) so the mailbox can be
driven end-to-end in tests.
Tests: 66 unit + 27 instrumented, all passing on the API 37 emulator.

Folder view: a left navigation drawer lists each account's IMAP folders;
tapping one browses and caches that folder's mail. IMAP UIDs are unique only
within a folder, so message identity, the fetch/read/flag/delete paths, sync,
and the Room cache all became folder-aware (id = "accountId:folder:uid"; new
`folder` column; schema v7->v8). Standard folders (Inbox/Sent/Drafts/Spam/Trash/
Archive) surface with friendly names + icons via RFC 6154 SPECIAL-USE attributes
with a case-insensitive name fallback; the multi-account drawer adds an account
switcher and a unified "All Inboxes". INBOX stays the only auto-synced,
IDLE-watched, notifying folder; other folders sync on demand.
Lower minSdk 33 -> 29 for a rolling ~7-year Android support window; guard the
API-33 POST_NOTIFICATIONS runtime request accordingly.
Tests and CI:
- Bump espresso-core 3.6.1 -> 3.7.0 so Compose UI tests run on API 37
(3.6.1's InputManagerEventInjectionStrategy reflects a removed hidden method).
- New coverage across layers: FolderRoleTest, ImapClientTest folder cases,
MailboxViewModelTest, MailRepositoryImplTest folder routing, a FolderDrawer
Compose UI test, and LibreMailDatabaseTest folder DAO/reconcile tests.
- Gradle Managed Devices + a CI E2E matrix over every API 29-36; a single
"CI passed" gate job fans in all jobs and is required by branch protection.
- Non-blocking, custom-provisioned API 37 (preview) E2E job with image caching.
- Build + unit-test jobs run on arm64 (ubuntu-24.04-arm); emulators stay x86_64.

Search previously only filtered the cached inbox. Now a query also runs an IMAP SEARCH
on the server and folds the matches into the cache, so messages beyond the synced
window surface in the results.
- ImapClient.search(query) ORs SUBJECT/FROM/BODY terms and fetches matching headers
(extracted a shared toFetchedMessage mapper, reused by fetchRecentInbox).
- MailRepository.searchServer inserts/updates matches into the message cache (no
pruning); MailboxViewModel triggers it from a debounced, deduplicated search query.
- assemble/test/lint green, including a new ImapClient test asserting SEARCH returns
only the matching message against GreenMail.

Increment 4 — read.
- ImapClient.fetchBodyMarkingSeen extracts the best body part (HTML preferred,
else plain text) and marks the message \Seen; setFlag and deleteMessage (expunge)
back the star/read/delete actions.
- MailConnectionFactory shares credential/token resolution between sync and reader.
- Cached bodies survive sync: schema v3 (isHtml column via a data-preserving
Migration 2->3); sync is now insert-new + update-header + delete-absent instead of
replace-all, so fetched bodies are not clobbered.
- Reader fetches and caches the body on open (marking it read), renders HTML in a
hardened WebView (JavaScript off, file/content access off, remote content blocked
with an opt-in "Show images") and plain text in selectable Text; star + delete in
the app bar; a snippet is derived from the fetched body.
- Tests: GreenMail fetchBodyMarkingSeen unit test (body + read flag). assemble/test/
lint green; verified end-to-end on the Android 17 emulator against a local GreenMail
server (HTML rendered in the WebView, mark-read, snippet).

Increment 3 — receive.
- ImapClient.fetchRecentInbox pulls recent INBOX headers (ENVELOPE/FLAGS/UID)
over IMAP (password or XOAUTH2) into FetchedMessage.
- MailSyncer orchestrates per-account fetch -> Room (replace-per-account),
refreshing and re-persisting the Gmail OAuth token when needed.
- WorkManager background sync via a @HiltWorker (periodic 15-min + an expedited
one-shot after adding an account); Application supplies the HiltWorkerFactory
and the default WorkManager initializer is removed.
- Mailbox renders real cached mail with pull-to-refresh and proper empty states
(welcome/add-account vs no-messages); the sample-data crutch is removed.
- Shared entity mappers; MessageDao.replaceAccountMessages transaction.
- Tests: GreenMail-backed fetchRecentInbox unit test (deliver via SMTP, read via
IMAP, newest-first). Instrumented Keystore + Angus-provider tests stay green on
the Android 17 emulator, where the SyncWorker also runs to SUCCESS.
- Add error_prone_annotations to the compile classpath (Hilt/Dagger codegen).

Increment 2 — authentication and account management.
- Gmail OAuth 2.0 via AppAuth (Authorization Code + PKCE, restricted
https://mail.google.com/ scope); redirect scheme derived from the client id.
- Generic IMAP/SMTP manual setup (host/port/security) with an Advanced section.
- Angus/Jakarta Mail IMAP client (password + XOAUTH2); "test connection" logs in
and lists folders before an account is saved.
- Android Keystore-backed AES-256-GCM credential store (encrypts the OAuth
AuthState / IMAP password); accounts + secrets persisted in Room (schema v2).
- AccountRepository + Hilt wiring; Settings accounts list (add / remove).
- Tests: GreenMail-backed IMAP client unit test; instrumented Keystore round-trip
and Angus Mail provider-resolution tests (green on the Android 17 emulator).
- Remove the placeholder Compose smoke test (the API 37 Compose-UI-test library
hits InputManager.getInstance); on-device rendering verified via screenshots.
