// and surface a clean "cancelled" event before the task is

// Mirrors the Token handler's `ui.response_buf`/`ui.response_start_line`
// pair so reasoning streams render via the same buffered
// `replace_from + render_viewport` path the content stream uses.
//
// Previously reasoning used the inline `renderer.write()` path
// which paints per-chunk directly to stdout via per-segment
// `MoveTo`. Under certain conditions that path produces a
// staircase pattern (each chunk on a new row, offset by the
// previous chunk's end-column) — user-confirmed regression with
// current LLM streaming behavior. Buffered rendering paints
// every row at col=indent via `render_viewport`'s explicit per-
// row `MoveTo(0, i)`, so the issue can't manifest.
// dirge-fjqk: thinking is suppressed by default — it's noisy and low
// value. The animated "thinking" avatar is the live spinner; the
// reasoning text is buffered and revealed on demand with Ctrl+O (or
// streamed inline if the user flips this on with Ctrl+R).
// The tool_call_id of the in-flight chamber (or the most-recent
// chamber that was closed without a matching ToolResult yet). Lets
// the ToolResult handler distinguish "this result belongs to the
// currently-painted chamber" (sequential / single-tool case) from
// "this result belongs to an earlier call whose chamber was
// displaced by a parallel sibling" (the dirge-jzj scenario).
//
// When parallel tool execution is enabled (the default per
// agent_loop/types.rs), the LLM emits N ToolCalls back-to-back and
// the agent_loop's `execute_tool_calls_parallel` fires
// ToolExecutionStart for ALL of them before any ToolExecutionEnd.
// Each new ToolCall passively closes the prior chamber. Completion
// order is whatever finishes first, so ToolResults arrive
// arbitrarily — most never match the currently-open chamber's id.
// Without this tracker, mismatched results either landed inside
// the wrong chamber (path a, body painted under another tool's
// banner) or as a `↳ first_line` trailer below an unrelated chamber
// (path b). The fix: when a result's id doesn't match the open
// chamber, paint a fresh complete chamber for THIS id below the
// current scroll position. Completion-order rendering, each tool
// gets its own correctly-labeled frame.
// Tracks whether a tool chamber TOP has been drawn but no matching
// BOTTOM has been written yet. Used by the ask/alert handler to
// close the in-flight chamber BEFORE rendering the ALERT box.
//
// Why separate from `ui.last_tool_name`?
// The alert handler used to gate the chamber-close on
// `ui.last_tool_name.is_some()` — but in practice users reported the
// ALERT box rendering directly under an unclosed chamber TOP,
// meaning that check fell through. The root cause is subtle: when
// `tokio::select!` picks the ask channel after the ToolCall handler
// ran AND after a `close_tool_chamber_if_open` somewhere else
// cleared `ui.last_tool_name`, the chamber TOP is on-screen but
// `ui.last_tool_name` is `None`. Tracking the chamber visibility as
// its own boolean — set on every chamber TOP write, cleared on
// every chamber BOTTOM write — decouples the two state machines so
// the alert handler can rely on a fact about the *screen* rather
// than a fact about a name that has other clear sites.
// Buffer positions bracketing the chamber TOP (spacer + header
// banner). `ui.chamber_top_start` is the buffer length BEFORE
// those lines were pushed; `ui.chamber_top_end` is the length
// AFTER. If the chamber is closed passively (next ToolCall,
// notification, etc.) AND buffer_len() == ui.chamber_top_end (no
// body content was added in between), the chamber is dropped
// entirely via replace_from(start, []) — no orphan empty box.
// dirge-ov2 Phase C: per-chat UI state. When the user switches
// chats (Ctrl-N/P/X, /tasks), the locals above (ui.response_buf,
// ui.reasoning_buf, ui.last_tool_name, ui.last_tool_call_id,
// ui.tool_chamber_open, ui.was_reasoning, ui.agent_line_started,
// ui.response_start_line, ui.reasoning_start_line) get saved into
// `ui.chat_ui_states[old_active]` and the new chat's state is
// loaded into them. Hot-path event handlers reference the locals
// unchanged; only the chat-switch boundary pays for the swap.
//
// `ui.chat_ui_states[0]` mirrors the main chat from the start;
// subagent chats added later push new entries.
// dirge-ov2 Phase E: map subagent task id → chat index so
// Complete / Failed events can find the right chat window.
// Spawn creates the entry; Complete / Failed write to it but
// don't remove (so the user can scroll back later).
// dirge-781c: reverse mapping (chat-idx → subagent-id) so the
// Ctrl+K handler can resolve the focused tab back to a subagent
// id and forward it to `kill_subagent`. Built in lockstep with
// `ui.subagent_chat_map` at Spawn time.
// dirge-gek: per-subagent state for the left-gutter panel.
