Refresh the channel list when a message is deleted

[gpunto]

Goal

Deleting a message never refreshes the channel list rows. A message deleted only on this device (for example a send the
backend answers with a type="error" message, or a regular message in FAILED_PERMANENTLY) stays in the row's
Channel.messages until the next event for that channel. The stock preview shows the stale failed message, and apps that
build their own preview from the row's messages show the deleted error. Deletes that go to the server only update the
row once message.deleted arrives.

Closes AND-1575

Implementation

• DeleteMessageListenerState refreshes the channel in the active channel list queries after each delete step, as the
  send path already does.

Testing

DeleteMessageListenerStateTest checks the refresh for the local-only delete and for the request, success and failure
of a server delete.

On a device, using the grouped channels sample: send a message the backend answers with type="error" (text over 5000
characters), then hard delete it, and read the last message of the row's Channel.messages. On 6.44.2 it stays the
deleted message, also after a reconnect. With the change it is gone right away and the previous message is the last one. A server delete now updates the row when
the request goes out.

Summary by CodeRabbit

• Bug Fixes
  • Active channel results now refresh after a message is updated or deleted, keeping channel views in sync with the latest message state.
  • Channel results are also refreshed when a message deletion request starts and when it completes, whether it succeeds or fails. This helps prevent outdated channel information from remaining visible during deletion processing.

Walkthrough

The delete-message listener now refreshes active query-channel state after updating or deleting a message in channel and thread state. Tests cover refresh behavior across delete handling, including a case where refresh does not occur.

Tests cover precondition handling, delete-request start, and successful and failed results. A test verifies that precondition handling for a completed regular message does not refresh state.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 61965

In search results, a channel row can continue showing a deleted message as its preview. The issue is limited to that preview path and can be corrected by removing deleted IDs from the cache.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 61965

The refresh is limited to channel lists already active on the device and does not add a server request or expand access to channels. No introduced security issue was established, although concurrent and interrupted delete behavior remains unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The added projection is bounded to active query lists that already contain the message CID; the inspected path does not acquire another channel or a more privileged data source.

Trust Boundaries and Controls

• observed — The delete precondition still evaluates the locally held message against the current user before the local-only delete path; the added refresh receives that message’s CID, while the remote request continues through the existing client hooks.

Looks good. One question on the repro: getPreviewMessage only keeps regular/system messages, and the long-text send comes back as type="error", so I'd expect the row to skip it already after the send refresh. Was the stale row maybe a regular message in FAILED_PERMANENTLY or IN_PROGRESS? Not blocking, the fix covers those too.

[gpunto]

@andremion Right, the stock preview skips it. What stayed stale is the row's Channel.messages, which still had the deleted error. That shows up for apps that build their own preview from the channel's messages, for example to show a "message moderated" row for bounces; that's what the repro checked.

In the stock UI the same gap applies to your case: a regular FAILED_PERMANENTLY or IN_PROGRESS message is also deleted only on this device, with no event, so it stayed in the preview until the next channel event. And deletes that go to the server now update the row right away instead of waiting for message.deleted.
