## What changed
Add optional `inputImages` metadata containing each referenced local image's path and SHA-256 hash of the bytes read before normalization. Compute the hash from the same bytes used to prepare the edit request.
Preserve this metadata through completion events, persisted thread history, resume, and legacy rollout migration. Update app-server schemas and generated TypeScript and Python types; older items continue to deserialize without the field.
## Testing
Add coverage for input ordering, changed contents at the same path, unreadable or invalid references, serialization, persisted history and resume, and legacy migration.

## What changed
- Upload generated images to the attachment store and expose `fileId` in image-generation items when available, with inline `result` fallback on upload or decoding failure.
- Preserve file references through legacy events, persisted rollouts, thread history, and task output summaries. Keep model-facing image preparation separate.
- Add attachment request tags and mark generated-image uploads with `usage=image_gen`, preserving the thread's ephemeral setting.
- Update public schemas and SDK types to accept either image representation, retain the Python `ImageGenerationThreadItem` alias, and prefer `fileId` when reading records containing both fields.
## Testing
Add coverage for file-backed generation and rollout persistence, legacy history replay, inline and transitional serialization, task output visibility, and Python SDK alias compatibility.

## What changed
Render local viewed images and generated image artifacts as bounded thumbnails in the rich fullscreen transcript using Kitty or Sixel graphics. Viewed images appear when their activity is expanded or the detailed presentation is active; generated images appear alongside their saved-path entry.
Keep previews clipped to the viewport, retain graphics across unrelated redraws, and remove them when overlays open. Bound image decoding and cache memory, and preserve text-only entries for remote workspaces, unsupported terminals, missing files, and oversized images. Image rows do not enter searchable or selectable text.
## Testing
Add layout and snapshot coverage for disclosure, viewport clipping, rewrapping, raw-mode fallback, deleted files, and oversized rasters. Add terminal coverage for retained Kitty graphics, repainting after a clear, local-file transport, and overlay cleanup.

## What changed
Add `model` and `reasoningEffort` to `subAgentActivity` items for multi-agent v2 spawns. Capture startup settings before the child begins its turn and resolve the reported effort against model metadata, including model defaults, while preserving the child's configured effort.
Carry these fields through live notifications, persisted activity, thread history, and legacy rollout migration. Update the JSON schemas and generated TypeScript and Python types. Older records and other activity kinds retain null values.
## Testing
Add coverage for resolved spawn settings matching the child's request across legacy and paginated history, preserving configured effort, forwarding metadata through events and history, and reading and migrating older records without the new fields.

## 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
Render Control, Shift, and Alt as `⌃`, `⇧`, and `⌥` on macOS, and Control as `^` on Linux. Keep textual modifier labels on other platforms.
Route hard-coded shortcut hints through the shared key-label formatter so footers, overlays, pickers, and transcript notices use consistent notation.
## Testing
Update modifier-combination and chord label assertions, along with rendering snapshots and narrow-layout expectations for the shorter hints.

## Why
Command execution analytics lack the observed sandbox backend. Older execution servers may omit this information, so an unknown backend must remain distinguishable from an explicitly unsandboxed process.
## What changed
- Carry optional `sandbox_type` metadata through command execution items and emit its metric tag as `sandbox_backend` in analytics.
- Propagate the observed backend through unified execution completion and failure events, including asynchronous exits.
- Preserve missing backend information as `None` and mark executed user shell commands as `Some(SandboxType::None)`.
- Exclude the metadata from serialized command items and generated schemas and TypeScript types.
## Testing
Extend tests for missing and explicit executor backends, backend propagation on failed execution, and analytics payloads, including platform-specific backend tags in app-server integration coverage.

## 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
The TUI ignored dynamic tool items, and replayed tool activity could differ from live output. Concurrent tool completion also needs to preserve transcript order when writing to terminal scrollback.
## What changed
- Retain dynamic tool rows, update them when calls finish out of order, and mark unfinished calls interrupted when a turn ends.
- Queue terminal output behind unfinished dynamic tools and drain settled rows in bounded batches. Preserve queued output through stream consolidation, resize, and rollback without emitting it twice.
- Align replayed file changes, MCP results, and exploration groups with live rendering. Keep hidden reasoning and terminal interaction details within compatible activity groups, and preserve finalized plan fragments.
- Ignore stale history-page responses, bound turn metadata requests to missing turns, and insert older history after session headers. Keep hidden review prompts as activity-group boundaries.
## Testing
Add regression tests and snapshots for out-of-order tool completion, interruption, ordered scrollback emission, rollback, deferred usage updates, replay consistency, overlapping history, and repeated hidden prompts.

## 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.
GitOrigin-RevId: a716db571440f891cc2c6894ae93fbe0e149aed4
## Why
Loaded transcripts reduce several tool calls and file changes to basic status summaries, losing details available in live history cells.
## What changed
- Reuse rich history cells for completed commands, MCP calls, patches, agent activity, image generation, and notices.
- Add dynamic tool cells with bounded output previews while retaining arguments and full output in detailed and raw views.
- Preserve last-known statuses for incomplete calls, unavailable results, and declined or failed operations. Keep legacy command text and terminal interaction output when rich reconstruction is unavailable.
- Remove redundant move annotations from patch diffs and retain patch activity IDs.
- Filter untrusted control characters before emitting terminal scrollback, while preserving semantic hyperlinks.
## Testing
Add unit and snapshot coverage for compact and detailed tool rendering, status fallbacks, retained output, patch restoration, and control-character filtering with and without hyperlinks.
