Stop the sync manager from storing a rejected retried message as sent

[gpunto]

Goal

A message queued while offline and retried by the sync manager on reconnect can come back from the server as a
rejection: a 201 with the message echoed as type: "error" (frozen channel, before-send hook). The send listeners
persist that echo, but the retry then wrote the local regular message back to the database as COMPLETED,
overwriting it. In memory the echo wins, so nothing looks wrong until the app restarts and the channel is rebuilt
from the database: the rejected message renders as sent, the mark-read guard sees a server-side message, and the
SDK marks an empty channel read. The server then emits message.read with no last_read_message_id.

Closes AND-1540

Implementation

• SyncManager.retrySendingOfMessageWithSyncedAttachments no longer writes the local copy back on success. The
  send listeners already persist the server's reply with COMPLETED, which also drains the retry queue. The
  permanent-failure marking is unchanged.
• Message.isLocalOnly() also returns true for a COMPLETED message with no createdAt. A server-confirmed
  message always carries one, so this covers rows already written by the old code and stops the bogus mark-read on
  existing installs without deleting anything.

Testing

• SyncManagerTest: a SYNC_NEEDED message whose retry returns a rejection echo is never written back (fails on
  the old code with a type=regular, syncStatus=COMPLETED write), and a permanent failure still marks the row
  failed.
• MessageUtilsTest: new isLocalOnly row for a completed message without a creation date; existing rows pinned
  to a non-null date.
• Verified on a device with the Compose sample against a frozen channel, driving the backend with the Stream CLI:
  send while in airplane mode, freeze the channel, reconnect, force-stop, reopen. On the base build the message
  renders as sent, the controller sends the mark-read and the server's last_read for the user moves to the open
  time. On this branch the message renders as an error, the controller logs rejected (no server-side message),
  no /read request is sent and last_read stays at channel creation.

Walkthrough

The change treats messages without a creation date as local-only. Offline mapping marks completed undated messages as permanently failed. Retry handling now relies on the server-stored reply and persists permanent failures.

Changes

Message synchronization

Layer / File(s)	Summary
Local-only message detection stream-chat-android-client/src/main/.../MessageUtils.kt, stream-chat-android-client/src/test/.../MessageUtilsTest.kt	Message.isLocalOnly() returns true when createdAt is null. Parameterized tests cover dated and undated completed messages.
Offline status mapping and rejected-message persistence stream-chat-android-offline/src/main/.../MessageMapper.kt, stream-chat-android-offline/src/test/.../MessageMapperTest.kt, stream-chat-android-offline/src/test/.../SendMessageListenerDatabaseTest.kt	Completed message entities without creation dates map to FAILED_PERMANENTLY. Tests verify this mapping and verify that rejected server error echoes are stored.
Retry persistence behavior stream-chat-android-state/src/main/.../SyncManager.kt, stream-chat-android-state/src/test/.../SyncManagerTest.kt	Retry sends no longer insert a locally constructed completed message. Permanent send failures are marked as failed. Tests cover rejected replies and 403 failures.

Merge Risk: 🔵 Low · up to 2e2a2

Rare locally persisted undated messages can trigger an unnecessary remote deletion attempt, while undated replies can still appear completed. The impact is bounded, but these synchronization-state inconsistencies should be addressed.

Block remote deletion of undated completed messages.

isLocalOnly() returns true for a completed regular message with createdAt == null, but shouldDeleteRemote() returns Result.Success(Unit) for it. DeleteMessageListenerDatabase then allows the remote delete flow instead of deleting the message only locally. Add createdAt == null to the local-only guard and add a matching test.

Apply the status correction to reply entities.

DatabaseMessageRepository.insertMessages persists message.replyTo through Message.toReplyEntity, which preserves COMPLETED with a nullable createdAt. ReplyMessageEntity.toModel returns that status unchanged. A local-only reply can therefore be exposed as completed, and shouldDeleteRemote() can return Success because it only blocks IN_PROGRESS and FAILED_PERMANENTLY.

Apply the same condition in ReplyMessageEntity.toModel, or centralize the status mapping in a shared helper. Add a reply-entity test for this state.

Both outside-diff findings from the last CodeRabbit review are valid and are fixed in d2817b8.

Block remote deletion of undated completed messages. Reachable through DeleteMessageListenerState, which takes the message from in-memory state (logic.channelFromMessageId(messageId)?.getMessage(messageId)) rather than the repository, so the status correction in MessageEntity.toModel never applies there. DeleteMessageListenerDatabase was already safe because selectMessage goes through the mapper. Added createdAt == null to the local-only guard in shouldDeleteRemote, with a test.

Apply the status correction to reply entities. Fixed as well. Rather than duplicating the condition I moved it into a shared correctedForMissingCreationDate helper used by both MessageEntity.toModel and ReplyMessageEntity.toModel, with a test covering the reply path.

One correction to the suggestion: the target status is FAILED_PERMANENTLY, not IN_PROGRESS, matching the existing correction on the message entity.
