## Why
Threads need a visible title while automatic generation is pending or fails. Hidden title-generation requests must also stay out of the foreground conversation, including during skill installation prompts.
## What changed
- Immediately display a Markdown-stripped, single-line excerpt of the first message, capped at 60 characters. Replace it with the generated title, or save the excerpt if generation fails or returns an invalid title.
- Give title threads explicit read-only permissions and request the `never` approval policy, subject to managed policy constraints. Keep blocking input requests on the hidden thread until timeout.
- Interrupt timed-out temporary structured turns before detaching them.
## Testing
Add coverage for provisional title replacement, fallback persistence, managed permission and approval policies, and hidden input requests. Add a terminal integration test that verifies title generation after choosing “Continue anyway” on a skill installation prompt.

## Why
Locally configured MCP servers may differ from those reported by the app server. Waiting for unreported servers can leave startup progress busy after the observed servers have finished.
## What changed
- Track startup progress from received server status updates, settling when no observed starts remain pending. Handle standalone outcomes after attachment or lag, deduplicate repeated diagnostics, and reactivate progress on new starts.
- Read effective MCP configuration through `config/read` to prevent task tools from shadowing the `codex_tui` namespace, including when configuration changes after startup.
- Use the same configuration reader to disable MCP servers for temporary structured threads.
- Remove client-side MCP requirement checks for the task-tools server and MCP requirements from debug configuration output, leaving enforcement to the app server.
## Testing
Update regression coverage for unreported local servers, startup rounds after lag, diagnostic handling, namespace conflicts, and server-enforced managed requirements.

## What changed
Read `final_answer_moderation` metadata and attach `moderation: { moderated: boolean }` to the completed final-answer message only when its item ID matches. Apply this in both normal and plan modes, and reset the pending decision when a new response starts.
Preserve the answer's native item ID and moderation flag through legacy events and history reconstruction. Combine text parts into one legacy event when a moderation decision is present.
Expose nullable moderation data on app-server agent messages and update the JSON schemas, TypeScript types, and Python models.
## Testing
Add an integration test for moderation on completed answers and their legacy events. Extend protocol conversion tests to cover populated moderation data and serialization as `null` when absent.

## 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.

## Why
Forcing `approval_policy` to `never` on temporary structured threads can trigger configuration warnings when managed requirements allow only `on-request`. These hidden threads also need to reject unexpected interaction requests without prompting the user.
## What changed
Inherit the app server's approval policy when starting temporary structured threads. Reject their server requests before dynamic tool handling or interactive TUI routing.
## Testing
Extend regression tests to verify inherited `on-request` approval without approval-policy warnings, and error responses for recap-thread approval and user-input requests even when the thread is marked active and primary.

## Why
Application network restrictions need to cover clients created by the TUI and `codex exec` before embedded app-server startup, and remain effective when configuration is rebuilt.
## What changed
- Introduce `EmbeddedNetworkPolicy` to share live policy between caller-owned transports and the embedded app-server.
- Apply loaded requirements before creating telemetry, background HTTP clients, and executor connections. Limit authentication and cloud configuration bootstrap requests to exact endpoints under local policy.
- Preserve the shared policy across TUI session changes, permission-profile rebuilds, and worktree cloud loaders so existing clients observe policy reloads and failures.
- Document application network policy behavior and transport coverage.
## Testing
Add regression coverage for policy activation, reload failure and recovery, retained policy across TUI rebuilds, rejected OAuth and cloud-policy redirects, and workspace network restrictions with `CODEX_API_KEY`. Also cover retaining the caller-selected project during embedded startup.

## Why
Managed permission profiles take precedence over the legacy sandbox override, so a managed `:workspace` default can prevent temporary structured threads from starting with the required read-only permissions.
## What changed
Set `default_permissions` to `:read-only` when starting a temporary structured thread without a custom permission profile. Preserve existing custom profile handling.
## Testing
Add coverage for a managed `:workspace` default, verifying read-only permissions when allowed and rejection when read-only is disallowed. Extend recap request assertions to check the read-only sandbox and permission configuration.

## Why
Memory consolidation and ephemeral title generation need to use their selected request-level reasoning effort even when managed settings enable reasoning-effort overrides.
## What changed
- Exempt current and legacy memory consolidation sessions and ephemeral `thread_title` threads from reasoning-effort overrides.
- Tag temporary title threads with `thread_title` and keep them excluded from agents overview refreshes. Recap threads retain the `system` tag.
- Preserve override behavior for persisted `thread_title` threads and other ephemeral threads.
## Testing
Extend regression coverage to verify request effort, omission of effort updates from exempt workers' requests, preservation of inherited history, title thread tagging, and overview filtering.
GitOrigin-RevId: 8dbc2eb13509f9c80f90d5798a56ea33fad2a0bc
## What changed
- Replace `send_user_message_async` with `request_user_input_async`, accepting one or more questions with optional suggested answers while allowing the turn to continue.
- Attach structured question metadata to asynchronous agent messages while retaining readable fallback text, and preserve it through app-server events, thread history, and generated schemas.
- Continue enabling the new tool for model catalogs that advertise either the old or new tool name.
## Testing
- Cover tool registration, question validation, emitted items, continued turn execution, history preservation, and backwards-compatible deserialization.

## What changed
- Give unnamed TUI threads an immediate provisional title from the first user message, then replace it asynchronously with a normalized generated title.
- Preserve manual renames by applying a generated title only while the provisional title is still current, and keep automatic rename notifications out of the transcript.
- Run title generation in a bounded ephemeral structured request that preserves custom permission profiles, otherwise uses read-only access, and disables tools and MCP servers.
## Testing
- Cover prompt and response bounds, Unicode-safe truncation, title normalization, manual-rename races, silent automatic updates, permission preservation, and structured-response failures.
