## What changed
- Stage Cloud speed choices for the next new turn in the conversation, alongside pending model and effort selections. Update the displayed conversation speed after admission without changing the local default.
- Offer speed commands supported by the pending model. Clear an incompatible pending speed change with a warning when switching models.
- Carry `service_tier` through Cloud message requests, preserving omission to inherit the thread tier and explicit null to clear it. Translate `default` to null and reject tier overrides on queued requests.
## Testing
Add tests for Cloud speed toggling, model-dependent speed choices, admission-time updates, and preserving the conversation tier when selecting a model. Extend request and wire tests to cover service-tier values, explicit clearing, and queue rejection.

## Why
A lost Cloud reply stream previously required reopening the conversation, even when it was idle. Recover the displayed conversation automatically while holding queued input until its reply stream is usable.
## What changed
- Add bounded retries for transient stream failures in the displayed, idle conversation, with credential and network-policy checks. Keep explicit reopen behavior when recovery is unavailable or fails.
- Enable HTTP/2 keepalive pings for Cloud connections.
- Queue input while disconnected and resume ordinary submission after recovery. Mark recovered history as potentially incomplete so an explicit reopen reloads missed turns while preserving drafts and reconciling pending submissions.
- Store retained input per backend and apply background settings updates to the owning backend's drafts.
## Testing
Add regression coverage for queued input during disconnection and extend resume and backend-handoff tests to cover history refresh, draft preservation, and retained settings.
GitOrigin-RevId: 3d753e53d3c0d594680a90cac8a75fe33b91e219
## Why
Command Center retains tasks across backend switches. Opening a retained task must use its owning backend, and restoring its draft must account for history or settings that changed while another backend was displayed.
## What changed
- Track each thread's first observed backend, reject conflicting ownership, and switch to the owning backend when opening a retained task. Require users to open tasks on other backends before running task actions.
- Keep discovery cursors, initialization, and pins per backend. Scope refreshes and usage requests to their owner, and handle background archive and delete notifications without consuming the displayed backend's pagination budget.
- Verify cached blank sessions are still idle and have no turns before reusing them, with a history-read fallback for older servers. Otherwise, resume saved history and preserve current server collaboration settings when restoring drafts.
- Use only interactive task-list pages for cloud discovery, which does not support the additional source filters.
## Testing
Add regression coverage for ownership conflicts, action routing, pins across backends, background removals, usage isolation, cloud discovery, and draft restoration with blank or populated history, including older-server fallbacks.
GitOrigin-RevId: 0d0913ec38dc16a839823008a4a84aa46ad8e6c6
## Why
Opening a saved side chat waits for thread resume and history loading. Keep the chooser usable during that work and switch conversations only if the user still wants to open the chat.
## What changed
- Prepare saved chats in the background and show opening, waiting, and retry states in the sidebar. Allow cancellation and keep only the latest queued destination, with at most two preparations in flight.
- Ignore stale completions after navigation, archiving, disconnects, or backend changes, and release unclaimed subscriptions on their original connection.
- Preserve live events, settings, read receipts, and pending approvals received during loading. Anchor paginated history to the resumed snapshot to avoid overlap with live events.
- Carry held-key suppression across conversation switches.
## Testing
Add regression tests for retry and supersession, cancellation, stale completions, subscription cleanup, live updates during attachment, and held keys, plus snapshots for waiting and retry rows.
GitOrigin-RevId: 2c7d94482078f16895049ce79b242d3eb0d92f40
## What changed
- Save side chats as attachments to their parent conversation when local workspace history supports them, and let users reopen them from the sidebar after a restart.
- Show chat names or first-prompt previews in sidebar labels, and allow saved side chats to be renamed with `/rename`.
- Add tab close buttons, middle-click closing, and the configurable `close_sidebar_tab` shortcut, defaulting to `Ctrl-X W`. Closing a saved chat keeps it available in the picker; archiving removes it from Side chats.
- Confirm actions that stop running work, discard unsent input, or lose temporary history. Delete saved TUI side chats when deleting their parent conversation.
## Testing
Add coverage for reopening saved side chats after restart, archive handling, close confirmations, and preventing close-confirmation keys from accepting a replacement approval dialog.
GitOrigin-RevId: 3d47533d007286a7354660c08df13a83dd48d5d7
## Why
Cloud messages previously accepted only plain text, and switching a draft to Cloud waited for session preparation without processing composer input.
## What changed
- Support ordered text and image parts in Cloud submissions and user-message summaries, preserving attachment placeholders, image detail, and client message IDs.
- Accept inline data URLs and uploaded file IDs, including image-only messages. Reject invalid references and text spans locally, and cap encoded image requests at 3.75 MiB while retaining the existing plain-text limit.
- Keep the composer editable and redraw the TUI while Cloud prepares a conversation. Carry the latest draft, attachments, and Vim mode into the destination, retain drafts on failure, and prevent submission to the outgoing session during the handoff.
- Preserve buffered paste input and pending clipboard reads across the handoff, with connection and failure hints.
## Testing
Add regression coverage for image wire encoding, receipt identity, validation and size boundaries, draft editing during successful and failed handoffs, clipboard completion, Vim state, and attachment recovery after rejected submissions.
GitOrigin-RevId: 0cbcde0ab89ba961780b5f88456057e6b6a19cd5
## What changed
Pass the local project's GitHub origin to cloud prewarming so new cloud threads can provision a repository checkout. Preserve the attached local project when switching backends and resolve its origin for each thread start.
Normalize supported GitHub origins to credential-free HTTPS URLs and select a repository-specific cloud working directory. Unsupported origins retain the blank environment behavior. Keep project metadata outside the app-server wire protocol, and fix HTTP Git URL parsing so query strings and fragments cannot be mistaken for authority text.
## Testing
Add coverage for project routing, origin normalization and rejection, managed environment encoding, local project retention, and Git URL credential stripping.
GitOrigin-RevId: 5859769965faf060461ccc1cbb3fd48f8e2f2155
## What changed
- Register an additional Cloud connection on supported macOS and Linux launches when `TuiMultiBackend` is enabled, using the selected ChatGPT account and local network policy.
- Preserve backend settings and identify Cloud in connection controls and status.
- Let Cloud supply the model when a thread opens, skip local skills requests and stale results, and allow resume without a local working-directory override.
- Preserve Git metadata in Cloud thread snapshots and continue history hydration past empty filtered pages within the scan budget.
- Report Cloud connection failures and require reopening Codex to reconnect.
## Testing
Add regression coverage for Cloud model bootstrap, skipped skills requests, resume directory handling, history pagination through filtered pages, and Git metadata preservation.
GitOrigin-RevId: 6717f0f5ad7708c5e9b5796d94711dd1eecc49bb
## Why
Starting a side chat waits for fork and setup requests. Keep the workspace responsive during those requests and let users return to an existing side chat through the sidebar chooser.
## What changed
- Add a clickable `Side chat` tab and `+` chooser, plus the configurable `focus_sidebar_tabs` action bound to `leader t` by default.
- Create workspace side chats in the background, showing loading and failure states with `Enter` to retry and `Esc` to go back. Preserve opening prompts and avoid taking focus when the user has moved away.
- Retain inherited permission profiles and defer startup notifications until the side chat is registered on its owning backend.
- Quiet the parent composer while the chooser has focus and prevent completion popups or repeated activation keys from consuming chooser input.
## Testing
Extend tests and snapshots for loading and failure states, returning to an existing chat, draft preservation, inherited permissions, focus transitions, and deferred MCP startup notifications.
GitOrigin-RevId: 244bcd3f170819e2260f21dc1041cf8899fe048c
## What changed
- Open a sidebar chooser when no side chat exists, with keyboard and mouse controls to start a new side chat while preserving the parent draft.
- Animate sidebar opening and closing, including reversing an unfinished transition, when animations are enabled.
- Show context-aware workspace shortcuts in a floating panel after a short delay, and render presets in the same overlay without moving the composer.
- Prevent chooser input from accepting an approval dialog before it has been painted.
## Testing
Add coverage for chooser activation and draft preservation, sidebar animation reversal, shortcut and preset snapshots, and approval input handling.
GitOrigin-RevId: 014112622a94798f4e611756c55112dfd8016051
## What changed
- Add Space to set the default provider from Model providers settings, persisting `model_provider` on the connected server. Keep provider details available and disable selection when server configuration or client launch settings fix the provider.
- Apply the choice to `/new` while preserving the current chat. Refresh account details for new chats and reject account data that does not match the started provider.
- Block stale `/model` choices during saves and after confirmed or uncertain provider changes, including across reconnects. Tell users to restart the app server and TUI to refresh the model list, and discard queued picker actions from another backend or chat.
## Testing
Add coverage for provider saves, retry after disconnection, concurrent-save prevention, stale model choices, and account/provider matching, with updated provider-picker snapshots.
GitOrigin-RevId: af6d149f7de7a2eaa09a31935f7088faa64d6a59
## What changed
Add configurable pane actions with default leader shortcuts:
- `leader z` zooms or restores the focused conversation pane.
- `leader ,`, `leader .`, and `leader =` minimize, maximize, or equalize pane widths within layout limits.
- `leader shift-h` and `leader shift-l` move the divider while the side pane has focus.
- `leader r` enters resize mode, highlighting the divider and showing keyboard hints. Arrow keys or `h`/`l` move it one column; Shift+Left/Right move it ten columns. Enter or Esc saves the width to `tui.sidebar_width_percent`.
Discard resize previews when terminal focus is lost or the split layout becomes unavailable. Preserve exact column widths at the current terminal size for presets and completed keyboard resizing, avoiding percentage-rounding drift.
## Testing
Extend TUI tests and snapshots to cover zoom and restore, width presets, divider movement, resize previews and persistence, and interrupted resizing. Extend keymap tests to cover zoom binding conflicts and custom chords.
GitOrigin-RevId: 7dd823fd8c2a0c90368c66f254c4fdd7c863c8a8
## What changed
- Allow dragging the pane divider and save the preferred width in `tui.sidebar_width_percent`, defaulting to one third of the terminal. Defer reflow until release when retained images are present.
- Support scrolling and loading older history in the unfocused pane, opening links, copying selections, and clicking its composer to switch focus while preserving the clicked text position.
- Keep assistant replies, running command completion, and turn status current in the unfocused pane without duplicating answers or completion metadata when focus returns.
## Testing
Add regression coverage for divider previews and saved widths, image-aware resizing, composer clicks, unfocused history pagination and copying, and streaming replies and command completion across focus changes.
GitOrigin-RevId: a26accc0f8df3c17f53bc915db29a11c8de3c480
## What changed
- Extend server-owned fresh-start bootstrap to embedded connections, preserving explicit profile and launch overrides.
- Require `config/read` to succeed before starting a fresh thread, including on servers that do not support the method.
- Prefetch `model/list` alongside `hooks/list` and reuse the result during bootstrap.
## Testing
Extend startup coverage for managed model and reasoning-effort defaults across embedded, daemon, and remote connections. Verify startup failure shuts down all initial backends, and directory-trust startup requests the model catalog exactly once while `hooks/list` is outstanding.
GitOrigin-RevId: c96edfbc13c98203b7c2a809a87d225e05cf5f1b
## Why
Pressing `Ctrl-/` immediately after `/btw` must not switch focus before the queued side-conversation prompt is dispatched.
## What changed
Wait for queued app events to drain before reading terminal input when the displayed thread belongs to a parent/side conversation pair, even when side retention is disabled. This keeps queued prompts and transcript updates ahead of focus changes.
## Testing
Extend the side-conversation startup test to toggle focus at the earliest allowed opportunity and verify that the turn starts on the side thread. Also check that a queued request to reopen the side conversation blocks terminal input until handled.
GitOrigin-RevId: cb46636d35de97b02994ed68a32eb971cd7bf6db
## What changed
Add `tui.keymap.global.hide_pane`, defaulting to `leader -` in workspace mode. Hiding a focused side conversation returns to its parent while retaining the conversation, drafts, and view state for reopening.
Expose the action in the workspace keymap picker, validate binding conflicts, and suppress held shortcut keys after switching focus.
## Testing
Add coverage for hiding and reopening at split-pane and narrow widths, preserving conversation state, shortcut availability, key capture, and repeat/release handling.
GitOrigin-RevId: 6897c34b208041e6f90ae0e18c781eebd62566bd
## What changed
- With multi-backend support enabled, show the current host before the first submission and use `leader b` to cycle through available connections. Expose the shortcut as `tui.keymap.global.change_host`.
- Preserve the conversation name and composer draft, including cursor position, attachments, pending pastes, and literal versus shell-command interpretation of `!`.
- Save explicit host choices in user-only `tui.default_hosts`, scoped to the local project and user identity. Use the saved host for new conversations, falling back to the first available connection when it is unavailable.
- Prepare the destination and check directory trust before replacing the current conversation. Block switching during voice calls and active turns, and remove replaced blank conversations from the session overview.
## Testing
Add coverage for shortcut visibility and remapping, draft and name preservation, project/user preference isolation, unavailable-host fallback, destination trust and startup failures, and voice-call guards.
GitOrigin-RevId: def7b088951336bec8fe3962954fba9b861f91c6
## What changed
- Add the disabled-by-default `tui_workspace` feature for the owned transcript view. At terminal widths of at least 100 columns, show the parent conversation beside its side conversation, with only the focused composer accepting input.
- Retain the inactive conversation's transcript, draft, and status, and restore reading and search state when switching focus.
- Keep drawing and input paused until history replay completes, while refreshing skills in the background.
## Testing
Add snapshots and regression tests for pane resizing and composer styling, retained streaming output, history search after replay, pending skills refreshes, and modal input protection.
GitOrigin-RevId: 68938f263353b0cd3a9e9562e06293bfc8251cc6
## What changed
Split conversation rendering into preparation, painting, and post-draw steps. Use the supplied conversation bounds for transcript wrapping, composer layout, suggestion overlays, cursor placement, and the empty-state animation.
Preserve surrounding text and image placements during input-triggered redraws. Keep centered dialogs relative to the full viewport and restore neighboring content when they close.
## Testing
Extend regression tests and add a snapshot for conversations rendered at an offset, covering selection, link hit testing, cursor placement, scroll preservation, neighboring images, and dialog dismissal.
GitOrigin-RevId: 0dbca3f8d1064f2d58856c3bc77a4dab1c099cdd
## Why
The session picker can list conversations from multiple backends, but selecting a conversation owned by another backend was rejected.
## What changed
- Resume selected conversations through their owning backend, preparing the destination before replacing the current conversation. Preserve drafts and restore the destination's settings, account state, model catalog, and workspace services.
- Block backend switches during an active turn and retain the current conversation when destination preparation fails.
- Queue background backend requests until that backend is displayed, removing requests that are resolved or disconnected. Isolate background events from the displayed conversation while continuing to deliver notifications to a background voice session.
- Track backend ownership for thread detachment, startup results, and reconnect attempts.
- Remove the `yaml-rust` advisory exception from `codex-rs/deny.toml`.
## Testing
Add regression coverage for backend handoff errors, detaching through the source connection, clearing stale provider errors, deferred request delivery and cleanup, and voice-session closure on a background backend.
GitOrigin-RevId: 1bba84f16831af1d5295c1404f48803ce0608d3d
## What changed
- List sessions from listening backends and the displayed session's backend using their existing connections.
- Give picker views distinct request ID namespaces while keeping connection ownership and event handling with the live sessions.
- Start multi-backend listings without a working-directory filter, since local and remote workspaces cannot share a single path filter.
## Testing
Add coverage for distinct picker request IDs, preserving the live event stream after picker shutdown, listing all providers after a provider switch while retaining the remote working-directory filter, and clearing the pending cursor when a source fails late.
GitOrigin-RevId: a0b8780e1f86dc187f088080d9213afe8e18f77f
## What changed
- Show draft attachment thumbnails in reference order in inline and fullscreen views on supported terminals with local workspaces. Display a `+N` count for attachments that do not fit, and preserve editable image references when previews are unavailable or space is limited.
- Refresh previews when attached files change, apply image orientation metadata, and clear frame graphics before terminal handoffs, screen switches, and shutdown.
- Finish CLI subcommand dispatch before polling interactive TUI events.
## Testing
Add a regression test and snapshot covering thumbnail order, overflow, resizing, attachment deletion, file replacement, and fallback behavior in both inline and fullscreen views.
GitOrigin-RevId: 1ea7c89e089cecc390e145c1790b6ede8bad8d5e
## Why
The agent command center previously required a shared background server, preventing embedded sessions from opening it and rejecting `codex agents --no-daemon`.
## What changed
- Allow `codex agents --no-daemon` to use an embedded app server and open the command center without a shared server.
- Route `codex agents` through the normal daemon startup, eligibility, and compatibility checks, including embedded fallback where applicable.
- Return embedded sessions to the command center when canceling directory trust or archived-session confirmation.
## Testing
Add CLI coverage for `--no-daemon` before and after `agents`, plus an integration test that verifies embedded mode is used even when a daemon is running. Update archived-session tests to expect cancellation to return to the command center.
GitOrigin-RevId: 3bdf18a00456eae2e4d38103d12126e039d44119
## Why
Command-center navigation required a shared app server, leaving embedded sessions without the same way to switch between chats. Archiving or deleting an embedded session also exited the TUI.
## What changed
- Enable command-center navigation and session listing for embedded sessions, including navigation from read-only conversations and the safety precaution menu.
- Return to the command center after archiving or deleting a session.
- Retain thread subscriptions when forking, including on embedded servers.
- Confirm before quitting an embedded server would stop running sessions or side conversations.
- Construct large startup and event-loop futures outside their callers' stack frames before boxing them.
## Testing
Add regression coverage for embedded session switching with background approvals and draft restoration, plus confirmation before quitting with a running side conversation. Update navigation, archive/delete, fork, and UI snapshot tests for the new behavior.
GitOrigin-RevId: 96bac48cccf85b685b58934d23dd1db93b663751
## Why
Switching model providers can hide saved chats from resume lookup or prevent them from opening. Keep their history readable when the server rejects resuming because of a provider mismatch, missing configuration, or policy conflict.
## What changed
- Include all providers in the resume picker, named resume lookup, and `resume --last`, while retaining provider filtering for fork lookup.
- Open chats with provider errors as read-only history and show an explanation with recovery shortcuts: `c` to continue in a new chat, `n` to start fresh, and `Esc` to choose another chat.
- Continuing in a new chat prepares an editable, unsent prompt referencing the saved conversation.
- Preserve drafts and rejected prompts or steers, suppress automatic submission, and retry provider admission when reopening the chat.
## Testing
Add coverage for cross-provider discovery, read-only history, configuration recovery, continuation drafts, rejected input recovery, error rendering, and Escape handling during transcript browsing.
GitOrigin-RevId: 5aaa7a404b9a6231101599adef18d2f1e4a8020a
## What changed
- Allow `/quit` and `/exit` while offline, exiting without waiting for server shutdown.
- Retry `thread/resume` when the server reports `serverShuttingDown` instead of treating the conversation as unavailable.
- Report which reconnect stage timed out, including waiting for server shutdown, without exposing transport errors that may contain endpoint credentials.
## Testing
Extend regression coverage for offline quit commands and stage-specific timeout messages. Update the reconnect integration test to exercise a draining server and verify that local approval and sandbox settings are preserved.
GitOrigin-RevId: 4f6ed33db809f56ea09fc9423f3ffe28f22b7cc5
## Why
Terminal reports still in flight when Codex exits can leak into the parent shell's input.
## What changed
Pause terminal event polling during shutdown and flush pending input before restoring normal terminal input mode. On Unix, use a primary device attributes (DA1) reply to wait for outstanding reports after disabling reporting, with a two-second timeout when startup detected DA1 support. During panic unwinding, flush queued input without locking the event reader.
## Testing
Extend PTY tests to cover mouse-report bursts with a split DA1 reply, clean shell input after exit, and queued input cleanup during panic unwinding.
GitOrigin-RevId: 304859b654fb2b2c8882e6cac4cb6522fe05475c
## Why
Mouse capture prevents the terminal from handling link-opening gestures in expanded questions.
## What changed
Disable mouse capture while questions are expanded and the TUI owns the screen, unless an interactive modal is active. Restore the default capture policy when questions collapse.
## Testing
Add a regression test covering expansion, collapse, non-owned screens, and link visibility with warnings open.
GitOrigin-RevId: 1fd37feb5c9cd374b492218eeef8c80316bb1cf9
## What changed
Replace screen-specific `OverlayInput` variants with `MouseCapture::{Inherit, Enabled, Disabled}` and rename the setter to `set_mouse_capture`.
Preserve existing capture behavior: transcript and usage overlays enable capture, onboarding and static pagers disable it, and the inherited policy follows screen ownership. Update the alternate-screen and lifecycle tests to use the new policy.
GitOrigin-RevId: 965a3bb6d0854e289d2b0dbeedbf2b252b98293d
## Why
Remote App Server sessions support the command center, but the empty-prompt Left shortcut and its footer hint were enabled only for local daemon sessions.
## What changed
Enable the shortcut and `← for agents` hint for remote sessions. Centralize command center availability in `AppServerTarget::supports_command_center()` and use it consistently across navigation, lifecycle handling, trust prompts, and command center actions. Embedded sessions keep command center support disabled.
## Testing
Extend navigation coverage to verify the footer hint and opening the agents overview for both local daemon and remote sessions, while keeping navigation disabled for embedded sessions. Add a remote-session footer snapshot and update related UI tests to use the shared capability flag.
GitOrigin-RevId: 8148812217f68cf0fd441c35ed3c5b466ecc9cbd
## Why
NFS database migration rejected files with group or other access. Allow accessible databases to migrate while making the effects on file access explicit.
## What changed
- Preserve file mode bits during migration while requiring owner read and write permissions on replacement files.
- Before CLI consent, disclose that replacements belong to the current user and do not copy the original owner, group, or extended ACLs. Require explicit confirmation for files with permissions other than `0600`.
- Warn at Linux TUI startup when NFS databases need migration and permission confirmation. Inspect journal mode without accessing WAL shared memory or releasing another connection's locks.
- Allow five seconds to acquire the exclusive database lock during migration.
## Testing
Add CLI coverage for consent, access disclosures, and migration of `0644` files. Extend state tests for permission preservation, rejection of missing owner access, and interrupted migration recovery; snapshot the startup warning.
GitOrigin-RevId: 2d9c3663172c3e631a787dc1dc76db95c39e6aa1
## Why
Fresh TUI sessions sent the locally resolved approval policy in `thread/start`, overriding the app server's configured default. Local constraints could also prevent the TUI from adopting the policy returned by the server.
## What changed
- Send explicit approval policy overrides at startup and otherwise let the server resolve the policy. Preserve the resolved-config behavior for selected profiles.
- Forward granular `approval_policy` overrides with their replacement and dotted-key merge semantics.
- Forward eligible projectless approval defaults only when allowed by the server's approval policy requirements.
- Accept the server's startup policy before submitting initial or queued input, including when local constraints would reject it.
## Testing
Extend startup tests to cover explicit override precedence, granular policy merging, projectless defaults, and use of the server's approval policy on the first turn.
GitOrigin-RevId: 995ce5f21b04b058d60c2ea80a139c0cf48c0e98
## What changed
- Add `InitialBackendSessions` to carry the initial session and additional sessions into the TUI event loop. Existing launches continue to supply a single session.
- Shut down all supplied sessions on startup errors, cancellation, and early exits.
- Register the under-development `tui_multi_backend` feature flag, disabled by default, and expose it in the configuration schema.
## Testing
Add a regression test that fails bootstrap and verifies that both initial backends receive shutdown requests. Update multi-source event polling coverage to use the new initialization path.
GitOrigin-RevId: e5db439552de97594e6f13360b90be71256ab2f0
## What changed
Prefer frequently selected entries in the TUI's `$` picker within exact, prefix, and fuzzy match tiers, keeping stronger match tiers ahead of usage preferences.
Track the last 50 confirmed selections and persist them in `mention_usage.json` under `CODEX_HOME` when history persistence is enabled. Preserve in-memory preferences across compatible chat widget replacements, including when history persistence is disabled. Serialize background writes, merge updates under a bounded file lock, and flush pending writes on shutdown.
## Testing
Add coverage for picker ordering, preference handoff and persistence, history-disabled widget replacement, selection expiry, malformed history, and lock contention.
GitOrigin-RevId: 7efa8c1c365e23000fcda10dbbc2a7e90f4e777c
## Why
A remote server can refuse the initial `thread/start` while shutting down. An explicit refusal establishes that no thread was created, allowing the TUI to retry without risking duplicate startup submissions.
## What changed
- Wait for the draining connection to close, reconnect within a shared two-minute deadline, and retry startup once.
- Preserve the initial prompt, confirmed draft, model, and reasoning effort across recovery. Keep drafts editable and allow cancellation of a pending submission.
- Restore input without submitting if recovery fails or startup is refused again. Continue treating a lost startup reply as uncertain and avoid automatic resubmission.
## Testing
Add regression coverage for successful reconnection with exactly one prompt submission, repeated refusal, disconnect event ordering, and draft cancellation, editing, and paste provenance during recovery.
GitOrigin-RevId: 85b756e14f29c239c4774af2b32215fe251530ac
## What changed
Add a `BackendSessions` collection to own app-server sessions and poll their events fairly with cancellation-safe receives. Track listening state per backend so pausing or closing one stream leaves the others available, and resume polling after reconnect. Shut down all registered sessions on exit.
Ignore background backend disconnect, lag, account, and rate-limit events that would otherwise update the displayed conversation's UI.
## Testing
Add coverage for polling three sessions, paused and closed stream isolation, cancellation, and session replacement after reconnect. Extend event ownership coverage to verify that background lifecycle and account events leave the displayed connection and rate-limit state untouched.
GitOrigin-RevId: 9ed82abc77aaf4bfeb86eb72161ad90fe20177ad
## What changed
Stop showing title-generation spinners in the footer, status line, and terminal title. Remove the associated UI pending state and animation refresh logic while retaining background title generation.
## Testing
Add a snapshot covering the footer and terminal title while automatic naming is pending. Update status-surface snapshots to cover thread names and ID fallbacks without progress indicators.
GitOrigin-RevId: 061456929149c216f0a98d7214179ec69cdaeee4
## Why
Events from another backend must not mutate the current backend's thread or connection state, even when native thread IDs collide.
## What changed
Attach the session's `BackendId` to incoming app-server events and check it before dispatching to thread caches or UI handlers. Apply the same check when waiting for a thread revert notification.
## Testing
Add regression tests covering ignored foreign notifications, approval requests, lag and disconnect events, accepted events from the current backend, and preservation of backend identity on transport events.
GitOrigin-RevId: 2577ab78e0592726f5f05e3426772899e6cb7c7e
## Why
A thread ID alone does not identify the backend that owns a session. Resume and fork selections must retain that ownership across connection replacement so they cannot operate on another backend, even when thread IDs match.
## What changed
- Add a process-local `BackendId` to app-server sessions and session targets, preserving it across reconnects and auxiliary picker connections.
- Reject selections from a different backend before changing session state or sending resume, fork, or unarchive requests.
- Disable local-daemon fallback to an embedded server for auxiliary pickers and after selecting a session, while retaining fallback for fresh startup.
## Testing
Add regression coverage for foreign selections with matching thread IDs, startup resume and fork rejection before requests, shared ownership across picker connections, and fallback eligibility.
GitOrigin-RevId: 05a3ca0a901a8dc24337d130548aa2c048b4d586
## What changed
- Add `terminal_columns` and `terminal_rows` buckets to `codex.tui.start`.
- Record `codex.tui.terminal_size` for new turns in the active thread and for resize bucket changes after the terminal size settles for 15 seconds. Reuse launch context and suppress duplicate turn notifications.
- Respect analytics consent for the built-in metrics exporter while allowing explicitly configured OTLP collectors. Apply consent checks to the active exporter across provider replacements.
## Testing
Add coverage for exporter replacement and consent after config reloads. Extend the PTY integration test to verify startup size buckets, turn-start observations, and delayed resize observations with analytics disabled and an explicit OTLP collector.
GitOrigin-RevId: e01a900cd3f04a36731078f725c75374596cb01b
## Why
Startup configuration warnings can reflect settings from when the background server started, even after those settings have been fixed. A restart lets users refresh the server without leaving the TUI.
## What changed
- Add a confirmed restart action to `/daemon`, warning that active or queued work in other chats may be interrupted. Reconnect automatically and let an in-progress restart finish if the TUI exits.
- Verify that Codex manages a local server before enabling restart, including servers discovered with auto-start disabled and those started by `codex agents`.
- Show a restart hint on the first startup configuration warning for managed servers, preserving the original diagnostic for copying and dismissal.
- Repaint the full surface of centered dialogs to restore background colors over cached blank cells.
## Testing
Add CLI integration coverage for agents startup and restarting a discovered daemon with auto-start disabled. Extend TUI tests for confirmation, cancellation, unmanaged servers, warning hints and dismissal, and dialog background rendering.

## What changed
- Group preferences into Appearance, Notifications, Input, Sessions, and Text selection tabs, with search and links to existing theme, status line, terminal title, and keyboard editors.
- Persist preference changes to the selected local configuration file, apply supported changes immediately, and show save errors, configuration overrides, and restart requirements in the panel.
- Add a delayed notification test and controls for notification timing while preserving custom event filters.
- Add `tui.copy_on_select_clear_selection`, disabled by default, to clear transcript selection highlights only after confirmed automatic clipboard delivery.
- Keep local configuration editors usable while disconnected and prevent held activation keys or buffered input from triggering actions across editor and reconnect transitions.
## Testing
Add regression tests and rendering snapshots for panel navigation, search, dependency states, editor handoffs, offline persistence, notification timers, custom filter preservation, and confirmed-copy deselection.

## Why
An unfinished terminal control sequence can prevent buffered input from draining before a startup modal appears. Propagating that timeout aborts modal handling instead of keeping the screen available for an explicit user decision.
## What changed
Treat input-drain timeouts as a reason to keep startup modal input quarantined. Discard key, paste, and mouse events while retrying the drain, and continue processing server events. Preserve this protection when another request resolves and when the agent overview is restored after reconnecting.
## Testing
Add a Unix PTY regression test covering unfinished control sequences, queued approval and overview shortcuts, unrelated request resolution, and overview reconnection. Verify that buffered input cannot answer an approval or create a task, while fresh shortcuts work after the drain completes.

## Why
WSL clipboard reads previously launched PowerShell for every paste. Process creation can hang under WSL and stall the shared clipboard worker.
## What changed
- Reuse a persistent PowerShell reader on a dedicated thread, keeping clipboard requests bounded by their deadlines and restarting the reader after errors.
- Prewarm the reader at startup when right-click paste is allowed on WSL, without accessing clipboard contents.
- Use length-framed UTF-8 responses to preserve whitespace and distinguish consecutive pastes while enforcing message size limits.
## Testing
Update the command-reader test to cover consecutive responses from one process, large clipboard text, UTF-8 and whitespace preservation, and read timeouts.

## Why
Fresh starts connected to an app server can bootstrap with stale client model settings before reading the server configuration. An empty model catalog can also prevent startup even when managed new-thread defaults provide a model.
## What changed
- Read server configuration before model bootstrap for fresh starts using a local daemon or remote server without an explicit profile.
- Preserve explicit model and reasoning-effort overrides, clear implicit client settings when `config/read` is unsupported, and allow managed new-thread defaults to supply a model when the catalog is empty.
- Use the launch directory for local daemon configuration reads and the server directory for remote reads.
## Testing
Update startup-default tests to cover managed model selection with an empty catalog. Strengthen the reconnect test with a stale client model and an assertion that `config/read` uses the server directory.

## Why
Command Center previously reset to project grouping on startup, losing the user's selected grouping.
## What changed
Save grouping changes to `tui.agents_overview_grouping` in the client’s user configuration and restore the saved choice at startup. Support `project`, `status`, and `model`, with `project` as the default. Report save failures in Command Center while keeping the selected grouping active.
## Testing
Add tests for cycling through and persisting all grouping modes, preserving unrelated settings in a custom configuration file, displaying save errors, and restoring saved grouping during startup.

## Why
Account-update notifications include authentication mode and plan information but
omit the email, causing `/status` to lose the signed-in account's email after an
update.
## What changed
Fetch the ChatGPT account email asynchronously after account updates, with a
30-second timeout, without blocking terminal input. Apply the result only if its
request ID is still current, invalidating pending results on subsequent account
updates and disconnects.
## Testing
Extend the account-update test to verify that the email is restored and a stale
result is ignored. Update the status snapshot to include the account email and
plan alongside credits and limits.

## What changed
Expose `create_worktree`, `get_worktree_creation_status`, and `list_worktrees` through MCP when the worktrees feature is enabled for a trusted local project and attachment storage is available. Support both embedded and local daemon sessions.
Create worktrees asynchronously and attach them to the requesting task, with ownership and attachments retained across restarts. Default to the repository's remote default branch unless `ref` is supplied. Keep the task's working directory and execution environment unchanged, and leave uncommitted source changes in place.
Reject creation in ephemeral side conversations and explicitly untrusted source projects, reuse pending operations, and reject configured MCP servers that conflict with the TUI tools namespace.
## Testing
Add integration and model-request snapshot coverage for creation, polling, listing, attachment persistence across restart, task isolation, trust checks, namespace conflicts, and worker failure reporting.

## Why
Fresh TUI threads should use the app server's model settings unless the launch explicitly overrides them. Sending resolved configuration values in `thread/start` turns defaults into explicit overrides.
## What changed
- Track explicit launch choices for `model`, `model_provider`, and `model_reasoning_effort`, and omit unselected settings from the initial `thread/start` request.
- Preserve accepted model migrations as explicit model and reasoning-effort choices.
- Keep explicit profile launches on the existing resolved-configuration path.
## Testing
Update startup request tests to cover omitted defaults, CLI model and provider overrides, repeated model overrides, reasoning-effort overrides, accepted migrations, and explicit profiles.

## What changed
Select cyber refusal notices from the current model's `available_access_programs` for ChatGPT accounts using the OpenAI provider. Show Astra-specific guidance only when an Astra model offers standard cyber access without Daybreak access, and use the limited notice when Daybreak access is available. Otherwise, show application guidance.
Remove the separate account eligibility request, background prefetching, and notice cache.
## Testing
Update tests to cover catalog-based notice selection, missing model metadata, isolation from other models' access programs, and rendering the application notice for a cyber policy error.
