## What changed
Replace `UserHistoryCell`'s `spoken` boolean with `UserMessagePresentation`, defaulting to `Plain` and using `Spoken` for speech transcripts. Route rendering checks through `is_spoken()`, preserving the existing prompt styling and whitespace handling.

## What changed
- Add nullable `startedAtMs` and `completedAtMs` fields to `ThreadItem` in live notifications and turn history. Values are Unix milliseconds when recorded.
- Preserve recorded item times through history reconstruction, pagination, and resume, including command start times recorded during approval.
- Separate the Rust item payload into `ThreadItemPayload` while keeping the JSON payload flat, and update consumers, schemas, and generated TypeScript and Python types.
## Testing
Extend coverage for timestamp serialization, history reconstruction, paginated reads and resume, and persisted Python SDK items.

## Why
Clients starting delegated work need to attribute descendant turns to the original turn and retain that attribution through completion and history reads.
## What changed
- Accept optional `parentTurnId` and `rootTurnId` in `turn/start`, and expose `rootTurnId` on returned turns and lifecycle notifications.
- Default new turns to their own root when none is supplied. Preserve the active turn's root when steering, ignoring incoming lineage fields.
- Carry root IDs through completion, interruption, recovery, and fork boundaries, and persist them for paginated history reads. Leave unknown roots null in older history.
- Update protocol schemas and generated TypeScript and Python bindings.
## Testing
Extend coverage for default and explicit roots, steering without changing lineage, interrupted and recovered turns, history reads after restart in both history modes, nested fork pagination, and compatibility with older database writers.

## What changed
- Add mouse selection, word and line selection, drag autoscrolling, and keyboard selection with `Ctrl+Space`. Support copying selected text and opening links with a modified click.
- Anchor reading positions and selections to source text so resizing, streaming completion, and history pagination preserve the displayed content. Preserve hard line breaks, indentation, tabs, and graphemes when copying, while excluding display gutters and soft wraps.
- Rejoin activity groups split across history pages while retaining the reader's displayed revision.
- Distinguish confirmed clipboard writes from unconfirmed terminal requests, and retain native clipboard ownership after the transcript overlay closes.
- Manage mouse capture and keyboard modes across overlay transitions, editor handoffs, and suspend/resume.
## Testing
Add regression tests for selection during live updates and pagination, source-text copying across resize, clipboard confirmation and lifetime, and terminal mode restoration.

## Why
Persisted transcripts rendered tool calls individually and displayed reasoning differently from live replay. Enabling raw reasoning also replaced the summary instead of retaining it.
## What changed
- Group computer activity and compatible exploration commands across intervening reasoning, retaining details for the expanded transcript. Respect visible content, command failure boundaries, and turn boundaries.
- Separate paginated history at every turn boundary before filtering hidden items, while adding completion metadata only for successful turns.
- Keep persisted reasoning out of the compact display, preserve hyperlinks in detailed rendering, and append enabled raw reasoning to the summary. Preserve standalone reasoning Markdown in transcript exports.
- Add helpers to rejoin activity groups and attach reasoning across page boundaries using persisted item identities and turn adjacency.
## Testing
Add regression coverage for reasoning replay parity, computer groups split across history pages, turn boundaries, and grouped terminal input. Update export and raw-reasoning tests to verify retained summaries and Markdown.

## What changed
- Render web activity on one line with width-aware truncation and labels for searches, opened pages, and in-page searches. Preserve all batched queries in full details.
- Show viewed images by filename in chat while retaining their original paths in expanded transcripts and raw output. Use these activity renderers for persisted transcripts and exports.
- Display code-mode tool titles without the `Calling` or `Called` prefix and truncate headers to the available width while preserving full transcript titles and failure details.
- Keep `Returned image` markers inside the originating MCP call, alongside result text, and use the same wording in transcript exports.
## Testing
Add regression tests and snapshots for narrow displays, missing web action details, batched queries, image paths, MCP image results, matching live and replay rendering, and complete web and image details in persisted exports.

## What changed
- Render spoken user prompts with a bold red chevron, preserving its color during live transcript animation. Trim leading whitespace for display while retaining the raw transcript text.
- Underline and link file references such as `src/lib.rs:42` in spoken assistant transcripts using terminal hyperlinks. Preserve existing links and support Windows-style relative separators.
- Restrict generated file links to existing files with allowed extensions inside the workspace, rejecting hidden paths, traversal, and symlink escapes.
## Testing
Add rendering and transcript tests for the spoken marker, raw text preservation, file links, Unicode column offsets, and Windows-style paths, plus validation tests for rejected file destinations.
GitOrigin-RevId: 5fa180aa606acdc579a916441520602cb2bf3655
## What changed
- Add `/export` with clipboard and file destinations, including a default filename prompt and support for an explicit path argument.
- Export the complete conversation history as structured Markdown, preserving user and assistant messages, plans, reasoning, activity, image labels, file changes, and MCP tool details while honoring reasoning visibility.
- Fall back to legacy history loading when pagination is unavailable, and use the visible transcript for ephemeral sessions.
- Resolve relative and home-relative paths without overwriting an existing file, and report export or copy results in the conversation.
## Testing
- Cover Markdown rendering, hidden review prompts, activity details, complete paginated and legacy history loading, destination prompts, status messages, path resolution, and overwrite protection.
