14-14: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick winReport payload decode failures instead of discarding them.
serde_json::from_value(...).ok()maps any decode failure toNone. The callers insrc/acp/commands/auth.rsthen send no event and no diagnostic. If the agent changes a field name or returns an error-shaped payload, the OAuth start, complete, and logout actions appear to do nothing in the UI.Keep the tolerant return type, but surface the decode error to the diagnostics log so the failure is observable.
♻️ Example: capture the decode error before dropping it
async fn result_call<C: AcpConnection>( connection: &C, method: &str, params: serde_json::Value, ) -> Result<Option<OAuthResult>, acp_sdk::Error> { let response = call(connection, method, params).await?; - Ok( - serde_json::from_value::<OAuthResultDto>(payload(&response).clone()) - .ok() - .map(result_from_wire), - ) + match serde_json::from_value::<OAuthResultDto>(payload(&response).clone()) { + Ok(dto) => Ok(Some(result_from_wire(dto))), + Err(err) => { + tracing::warn!(method, error = %err, "auth payload decode failed"); + Ok(None) + } + } }Also applies to: 28-30, 66-68

- Around line 191-194: Update the model_id parsing fallback in the
provider/model construction to use model_id as the model value when no slash is
present, matching fallback_model; keep the provider fallback as "unknown" and
preserve the existing split behavior for provider/model identifiers.

In `@src/features/chat/view/header.rs`:
- Around line 125-127: Update the status-matching logic in the delegate count to
increment done for DelegateStatus::Failed as well as Completed and Cancelled,

passing it to compensate_chat_growth and clamp_chat_scroll, preserving correct
scroll behavior.
In `@src/features/navigation/view/theme.rs`:
- Around line 338-424: Rewrite the three tests around build_theme_list_item to
render each returned ListItem through TestBackend, then inspect the buffer for
the actual marker, sixteen swatch block characters, and their foreground colors
instead of rebuilding Lines or asserting proxies. Update
theme_list_item_marker_active_vs_inactive and its documentation to expect the
implementation’s "● " active marker and " " inactive marker.
In `@src/features/profiles/view.rs`:
- Around line 115-119: Update the scroll_input call in the profiles view to pass
the character count of profile_filter rather than its byte length, while

connection so ConnState::Disconnected uses the hollow CONN_OFFLINE symbol, while
preserving the existing colors and other ConnState mappings.
- Around line 135-139: Update draw_header’s width calculations for left spans,

agent-client-protocol Rust 1.0.1 ToolCallUpdateFields status title raw_input partial update schema
💡 Result:
In the Agent Client Protocol (ACP) Rust SDK, ToolCallUpdateFields is a struct designed to represent partial updates to an in-flight tool call [1][2][3]. The Rust SDK achieved version 1.0.0 on June 25, 2026, and 1.0.1 on June 29, 2026 [4][5]. The ToolCallUpdateFields struct is defined as follows: #[non_exhaustive] pub struct ToolCallUpdateFields { pub kind: Option, pub status: Option, pub title: Option, pub name: Option, // Available behind 'unstable_tool_call_name' feature pub content: Option<Vec>, pub locations: Option<Vec>, pub raw_input: Option, pub raw_output: Option, } Key characteristics of this schema include: 1. Partial Updates: All fields are optional (Option) [1][2][6]. Only the fields included in the update are modified; absent fields remain unchanged in the target tool call [2][3]. 2. Collection Handling: Fields containing collections (content, locations) are designed to overwrite existing values rather than append or extend them [1][2]. 3. Raw Input/Output: The fields raw_input and raw_output utilize serde_json::Value to handle arbitrary data [1][2][7]. 4. Unstable Features: The name field is marked as unstable and is only available when the unstable_tool_call_name feature is enabled in the crate [1][7]. 5. Serialization: The structure typically uses camelCase for JSON serialization, and fields are often annotated to skip serialization if they are None [3]. This struct is utilized within the broader ToolCallUpdate envelope, which pairs the update fields with a tool_call_id to target the specific invocation being updated [6][3].

Preserve partial ToolCallUpdate semantics.
ToolCallUpdateFields is partial in agent-client-protocol 1.0.1. A status-only update currently becomes AcpSessionUpdate::ToolCallStart with name "tool" and no arguments. The reducer avoids duplicate tool entries by tool_call_id, but the tool boundary still flushes assistant streaming content and applies start handling.
Represent intermediate updates separately, merge them by tool_call_id, or ignore unsupported updates. Add a test with an initial ToolCall and a status-only ToolCallUpdate that asserts no extra tool-start boundary or assistant flush.

A connected peer that never responds can retain entries indefinitely. Add cancellation-safe cleanup and a regression test that aborts the request task after receiving the frame, then asserts pending_len() == 0.

Clamp the custom-editor cursor to the popup bounds.
In a 3-column frame, inner.width is 1. Line 351 sets the cursor x-coordinate to the frame right boundary before it adds cursor_col. This places the cursor outside the visible frame when the custom editor is active.
Clamp the x-coordinate to inner.right().saturating_sub(1), or skip cursor placement when the editor has no usable text area. Add a narrow-frame regression test.

Complete the large-chat offset migration.
total_card_height can now exceed u16::MAX, but RenderState::chat_scroll_offset() still stores a u16 offset and Card::render clamps clip_top to u16::MAX.
For a one-row viewport with a single 66,000-row card, bottom pinning produces clip_top = 65,999. The paragraph then starts at row 65,535 instead of the latest row. For multi-card histories, users also cannot scroll more than 65,535 rows upward.
Store the viewport offset as usize. Render cards with a path that can skip visual rows beyond Ratatui’s u16 paragraph-scroll limit. Add regressions for a single oversized card and for scrolling to the oldest row in a history above 65,535 rows.

Rust std::fs::write file permissions newly created file mode umask OpenOptions create documentation
💡 Result:
In Rust, std::fs::write is a convenience function that opens a file with default options, writes the provided contents, and closes it [1]. Because it uses default OpenOptions, you have no control over the file's initial permissions when using this function [1]. For precise control over file permissions at creation time on Unix-like systems, you must use std::fs::OpenOptions combined with the std::os::unix::fs::OpenOptionsExt trait [2][3]. Key details regarding file permissions and creation: 1. Default Behavior: When creating a new file using standard methods (without explicitly setting a mode), the operating system typically uses a default mode of 0o666, which is then modified by the process's umask to produce the final file permissions [4][2][5]. 2. Setting Permissions at Creation: To specify permissions at the moment of creation, use the mode method provided by OpenOptionsExt [2][3]. This method allows you to set the desired permission bits (e.g., 0o600 for owner-only read/write) [6]. rust use std::fs::OpenOptions; use std::os::unix::fs::OpenOptionsExt; let mut options = OpenOptions::new(); options.write(true).create(true).mode(0o600); let file = options.open("foo.txt")?; Note that the operating system will still apply the umask to the mode you provide [4][2]. If you need exact control regardless of the environment's umask, you may need to temporarily change the process umask or call std::fs::set_permissions immediately after creating the file [7][6]. 3. Changing Permissions After Creation: If a file already exists, you can modify its permissions using std::fs::set_permissions [8]. On Unix-like systems, you can use std::os::unix::fs::PermissionsExt to manipulate the permission bits directly [9]. Permissions-related code should be gated behind platform-specific attributes (e.g., #[cfg(unix)]) to maintain cross-platform compatibility, as these specific traits and methods are not available on all platforms [7][6].

Create the editor draft with owner-only permissions.
fs is std::fs, and fs::write creates new files with default permissions. With a typical Unix 022 umask, the draft gets mode 0644 in std::env::temp_dir(), so other local users can read initial_text. Use OpenOptions with mode 0o600 or a secure temporary-file API.

Clear RuntimeState::current_session_id after deleting the current session. Command::DeleteSession calls session::delete, which only sends DeleteSessionRequest. Since prompt still reads the unchanged session ID, deleting the current session can cause later prompts to target a deleted session.

Derive latest_activity from the maximum timestamp, not the first session.
SessionGroup::latest_activity documents the most recent activity in the group (see src/domain/session.rs lines 2-9). This code reads updated_at from the first session in the group. The order comes from response.sessions, and acp::ListSessionsResponse does not guarantee a descending order. If the agent returns ascending or unsorted results, the group shows the oldest timestamp. Also, the first session may have updated_at == None while later sessions carry a value.
🐛 Proposed fix
- latest_activity: sessions
- .first()
- .and_then(|session| session.updated_at.clone()),
+ latest_activity: sessions
+ .iter()
+ .filter_map(|session| session.updated_at.clone())
+ .max(),This comparison assumes a normalized ISO 8601 form. If the agent can return mixed offsets, parse the timestamps before the comparison.

Pending entries still leak when a caller cancels the request future.
The entry is removed only on send failure, timeout, or fail_all. session/prompt has no timeout, so an aborted prompt task leaves its PendingRequest in pending while the socket stays open. Use a guard that removes the id on drop, and add a regression test that aborts the request task after the frame is observed and asserts pending_len() == 0.

Bound the WebSocket handshake with a timeout.
connect_async has no deadline. If the peer accepts the TCP connection but never completes the handshake, run stays in this await forever. No ConnectionManagerEvent is published in that state, so the UI cannot show a failure and the user has no recovery path except restart. Wrap the call in tokio::time::timeout.

tokio-tungstenite 0.29 split stream automatic pong response flush
💡 Result:
In tokio-tungstenite (and the underlying tungstenite crate), pong responses to received ping messages are queued automatically [1][2]. These queued pong messages are written and flushed automatically during the next call to read, write, or flush operations on the WebSocket stream [1]. When you use.split to separate the WebSocket into a read stream and a write sink, the automatic pong response mechanism remains operational as long as the read side of the connection is actively being polled [3][4]. Because tungstenite maintains the internal state necessary to queue and flush these responses, simply ensuring that your application continuously reads from the stream (which triggers the internal progress necessary to process pings and flush the corresponding pongs) is sufficient [3][4]. If you are manually sending your own pong frames as heartbeats, you should be aware that the automatic pong response is also queued and processed by these same methods [1][2]. To avoid conflicts or to ensure that an automatic pong is not potentially delayed or overwritten in a way that interferes with your custom logic, ensure your writing task calls flush or write appropriately [1][4][2]. In highly sophisticated scenarios where you must strictly control the sequence of pong frames, some developers advise calling write_pending (where available) or ensuring the write sink is flushed before sending a custom message to guarantee the automatic pong has been dispatched [4][2]. However, for most use cases, the standard behavior of automatic handling upon reading/writing is intended to be sufficient and safe [3][4].

tungstenite 0.29 WebSocket read automatic pong queued flush split WebSocketStream source
💡 Result:
In Tungstenite 0.29, automatic responses to Ping frames are handled by queueing a Pong message internally [1][2]. When a Ping is received during a read operation, the corresponding Pong is placed in a write buffer [1][2]. Key behavioral details for Tungstenite 0.29 include: Automatic Flush: While general write operations in Tungstenite 0.29 do not automatically flush to improve performance, automatic responses such as Pong frames are an exception [3][4]. These queued automatic messages are written and eagerly flushed during subsequent calls to read, write, or flush [1][2]. Manual Pong vs. Automatic Pong: You should not respond to Ping frames manually, as the library handles this automatically [1][2]. If you send a custom Pong frame manually using write, and the library has an automatic Pong queued from a previous Ping, your custom message may replace the queued one [1][2]. To safely send a custom Pong after receiving a Ping, you must first call flush to ensure the automatic response has been sent [1][2]. Split WebSocketStream: When using tokio-tungstenite and splitting a WebSocketStream into a Sink and Stream (using split from the futures crate), the stream and sink become separate entities [5][6]. The underlying logic remains, but users must be aware that the automatic reply mechanism requires the underlying WebSocket protocol state to be driven [1][7]. If you are not using the integrated read/write methods, you must ensure that the sink is polled or flushed appropriately to process queued messages [1][7]. General Flush Requirement: Since version 0.20, Tungstenite has removed many implicit flushing behaviors [3][4]. Users are expected to explicitly call flush when they need to ensure that data has been fully written to the underlying stream, except for the aforementioned automatic responses which are eagerly flushed [3][4].

Forward automatic Pong frames through the writer. tokio_tungstenite 0.29 delegates socket.split() reads and writes to separate WebSocketStream operations. Tungstenite queues the automatic Pong when the reader processes Message::Ping, but the Pong is sent on a subsequent read, write, or flush. This reader ignores Message::Ping, and the writer waits for write_rx, so an idle connection can leave the Pong queued and trigger the peer’s keepalive timeout. Send Message::Pong through write_tx when the reader receives Message::Ping.
