The Rust SDK removed the low-level SecretStoreWrapper.putSecret/getSecret
API between 26.03.x and 26.04.x — it was an escape hatch we were using
to pin arbitrary bytes into a Matrix 4S slot. The SDK maintainers never
contracted that primitive; locking it down lets their recovery code
evolve without worrying about third-party storage.
This commit replaces that dependency with a self-contained design we
own end-to-end, so future SDK moves no longer break our backup flow.
### Design
- Slot: `com.sulkta.wallet.seed.v1` in Matrix account data.
Our namespace, not a Matrix-spec 4S slot — we are NOT impersonating
Matrix secret storage, we are holding our own opaque blob.
- Envelope (JSON): version tag, algorithm tag, random 12-byte IV, GCM
output (ciphertext || tag), AAD = slot name. AES-256-GCM via stock
javax.crypto. AAD binds a blob to its slot so a blob can't be lifted
from one namespace and successfully opened in another.
- Key: derived from the user's existing Matrix recovery key via
HKDF-SHA256 with info label "sulkta.wallet.seed.v1". The info label
guarantees we never produce the same key bytes Matrix uses for its
own crypto — same secret, different domain.
- I/O: client.setAccountData(key, json) + client.accountData(key)
via the SDK; the homeserver only ever sees the opaque encrypted blob.
### Files
- api/walletsecretstorage/WalletSecretStorage.kt — new interface
- impl/walletsecretstorage/WalletSecretEnvelope.kt — AES-GCM envelope
(with unit tests: round-trip, wrong key, tampered ct, tampered iv,
wrong AAD, wrong version, malformed JSON)
- impl/walletsecretstorage/RecoveryKeyDerivation.kt — base58 decode
+ parity check + HKDF-SHA256 (with unit tests: determinism,
whitespace tolerance, distinct info labels → distinct keys)
- impl/walletsecretstorage/MatrixAccountDataWalletSecretStorage.kt —
WalletSecretStorage impl wrapping Client account data
- test/walletsecretstorage/FakeWalletSecretStorage.kt — in-memory fake
- api/MatrixClient.kt: old .secretStorage → .walletSecretStorage
- features/wallet/.../WalletBackupServiceImpl.kt — rewired to use the
new interface; hasBackupWithoutKey now goes through the same path
instead of manually poking the raw Matrix HTTP API.
- DELETED: api/secretstorage/SecretStorage.kt, SecretStore.kt, impl/
secretstorage/RustSecretStorage.kt — the old SDK-dependent path.
### Backward compat note
Users who backed up a wallet seed on the OLD SDK have a blob in Matrix's
4S at `com.sulkta.cardano.wallet_seed`. This branch cannot read those.
Since the prior integration was only tested internally, acceptable
today — anyone with an old backup re-enters their mnemonic.
TracingConfiguration gained a required sentryConfig parameter between
26.03.x and 26.04.x. Pass null — we don't use SDK-side Sentry.
Timeline.sendRaw was moved off Timeline onto Room. Add sendRawEvent to
the JoinedRoom API interface, implement in JoinedRustRoom by calling
innerRoom.sendRaw, and have RustTimeline.sendRaw proxy through the
owning JoinedRoom. Our /pay event path keeps working without callers
having to know about the SDK move.
* Take into account homeserver capabilities: add `HomeserverCapabilitiesProvider` to check if the HS allows changing the user's display name or avatar. Also, modify the edit user profile screen to reflect these values.
* Add `/myavatar` command. Filter both `/nick` and `/myavatar` commands based on the homeserver capabilities.
* Update screenshots
* Assume the use can change their display name and avatar url if the capabilities check fails: if they try to change those, the HS will return an error anyway.
* Disable also `/myroomname` and `/myroomavatar` based on the HS capabilities.

Add threads list screen for rooms:
- Add `ThreadsListService` to subscribe to thread changes in the room.
- Create `ThreadsListView` and its associated node a presenters (the UI may change).
- Add a menu icon in the room screen to open it.
This is still pending info about unread threads, so several UI components related to it will be hidden.
* Add feature flag and use it to hide the access to this new screen

Adds SecretStorage interface and RustSecretStorage implementation
for accessing Matrix SSSS (Secure Secret Storage and Sharing).
This enables storing and retrieving encrypted secrets using the
user's recovery key.
Also fixes SDK compatibility issues:
- Remove deprecated Sentry configuration from TracingService
- Make analytics SDK enableSentryLogging a no-op
Requires updated Rust SDK with SecretStoreWrapper FFI.
- Add Timeline.sendRaw() to send custom Matrix events
- Add CustomEventContent type for receiving custom events
- Update TimelineEventContentMapper to handle MsgLikeKind.Other
- Update TimelineItemContentFactory to intercept payment events
- Rewrite DefaultPaymentEventSender to use sendRaw instead of text markers
- Update TimelineItemContentPaymentFactory to parse raw JSON
- Remove text-marker detection from TimelineItemContentMessageFactory
- Update tests to use raw event API
- Mark raw event SDK blocker as RESOLVED in BLOCKERS.md
Event type: co.sulkta.payment.request (reverse-domain format)
Status updates: co.sulkta.payment.status
Benefits:
- Proper Matrix protocol compliance
- No JSON embedded in text messages
- Events won't be indexed by search
- Clean separation from regular messages
* fix(deps): update dependency org.matrix.rustcomponents:sdk-android to v26.03.18
* Fix API breaks
* Add compatibility with rustls (#6367)
A new `rustls-platform-verifier-android` library has to be added to the project, it'll be called from Rust to get access to the certificates on Android.
Originally, this was supposed to be added as a local maven repo pointing to the rust crate that publishes the AAR, but that's just plain terrible (more details [here](https://github.com/rustls/rustls-platform-verifier#android).
Instead, what we can do is use a script that uses `cargo-download` to download the latest crate or a specified version, unzip it and add the `aar` file to the `:libraries:matrix:impl` module.
* Try fixing Sonar with local AAR files
* Remove `UserCertificatesProvider`: this is no longer needed after integrating rustls
* Added some docs for rustls and its `platform-verifier` library
* Upgrade SDK to `26.03.19`: this version contains a workaround that allows the app to use the same TLS verifier as before, fixing the Let's Encrypt issues we saw with some homeservers (like element.io)

* Make 'room list catch-up' analytics transaction network aware.
* Add `RoomListService.isInitialSyncDone`. Use this to simplify `DefaultAnalyticsRoomListStateWatcher`'s logic.
- Added `MediaSource.safeUrl` property replacing `withCleanUrl` method.
- Made `url` private so it can't be used externally.
- Reverted code in `CoilMediaFetcher`
- Also add tests
We've seen some MXC urls in the wild having some `mxc://foo/bar#auto` fragment suffix, which is invalid, but the URL before that fragment part is valid and can be displayed
* feat: Add history sharing badges to room details view
* tests: Add snapshots for history sharing room details badges
* fix: Disable soft-wrapping in badges, use FlowRow
* tests: Add unit test for `RoomDetailsState` and history sharing badges.
* tests: Add `MatrixBadgeAtomNeutralWrappingPreview` to exceptions
* chore: Re-order `MatrixBadgeAtom` previews
* fix: Add `Immutable` annotation to `RoomHistoryVisibility`.
* fix: Correct translation for shared badge
* Update dependency org.matrix.rustcomponents:sdk-android to v26.2.5
* Fix breaking API changes:
- Add temporary imlementation for `RustClientSessionDelegate.onBackgroundTaskErrorReport`, logging unrecoverable errors in background tasks of the SDK.
- Change `TimelineEventTypeFilter` to `TimelineEventFilter`.
- Support new `LatestEventValue.RemoteInvite`.
* Update the Rust SDK to `26.2.6`
* Fix API changes: `TimelineFocus.PinnedEvents` no longer takes any arguments
* Fix test fixtures: `NotificationItem` has a `rawEvent` field now

It shouldn't be in use, since it was never properly defined:
- The `Private` values coming from the SDK are considered to be `Invite` instead.
- Remove any existing `JoinRule.Private` usages in our code.
* When the user is in a v12 room, use different UI to select the last owner when leaving
- Add `LeaveSpaceRoom.areCreatorsPrivileged` to detect when this is happening.
- Import new strings.
- Build the new UI.
- Attach it to a change member roles screen navigation.
* Don't display the `isLastOwner` UI if the user is the only joined one in the room
* Rename `LeaveSpaceState.isLastOwner` to `.needsOwnerChange`. This way, it's easier to understand the difference with the passed `LeaveSpaceRoom.isLastOwner` value
* Add a test for the new check of user not being the last joined member
* Fix paddings in `LeaveSpaceView`
* Update screenshots
