## What changed
- Add `tui.resume_cwd` with `current` and `session` modes for resume and fork flows.
- Let users persist either mode directly from the working-directory prompt, while preserving one-time choices when no preference is configured.
- Apply the preference consistently during startup and in-app resume, honor explicit `--cd` overrides, and reject unsupported or unavailable directory choices with a clear error.
## Testing
- Cover configuration parsing and persistence, prompt behavior, startup and in-app flows, session metadata fallback, and remote workspace constraints.
GitOrigin-RevId: 7bf144c4b8c55bdb868cc8a71caf397c7740451a
## Why
Audio variants were available in the user-input protocol but were replaced with unsupported-input placeholders instead of being sent to the model.
## What changed
- Serialize audio data URLs as `input_audio` content and convert local `wav`, `mp3`, `m4a`, `webm`, and `ogg` files to labeled data URLs.
- Validate and canonicalize base64 audio before requests, enforce the 50 MiB input limit, and replace invalid, unsupported, or oversized audio with explanatory text.
- Preserve audio attachments when mapping response items back to user-message events and document the app-server input variants.
## Testing
- Add unit coverage for local-file conversion, data URL validation, size and format errors, event mapping, and attachment extraction.
- Add client tests that verify data URL and local audio payloads sent to the Responses API.
GitOrigin-RevId: f72cd6b6e43ab12757eeb47621b1d670594ac7d9
## Why
Assistant-authored inline visualizations need a terminal fallback that lets users open generated artifacts in a browser.
## What changed
- Recognize `::codex-inline-vis{file="..."}` directives in assistant Markdown and replace them with browser links during streaming, finalized history rendering, and local transcript previews.
- Materialize visualization fragments in sandboxed viewer documents with a content security policy, while restricting artifacts to HTML files within the thread's visualization directory and limiting their size.
- Show an explicit unavailable message for invalid or missing artifacts, hide incomplete streaming directives, and preserve directive text in code blocks and user Markdown.
- Add a trusted file-link path for generated viewers without enabling arbitrary `file:` links in Markdown.
## Testing
Add coverage for directive rewriting, streaming and replay, artifact validation, sandboxed viewer generation, trusted terminal hyperlinks, and literal preservation.
GitOrigin-RevId: a666b4ebc82bb5798ad45bd137fd815d538e1de2
## What changed
- Add remote and local audio variants to core and app-server user inputs, including generated JSON and TypeScript schemas.
- Preserve audio fields when converting app-server inputs and response content into thread items.
- Keep unsupported audio out of model requests, TUI rendering, text extraction, and truncated tool output, using explicit text placeholders where audio is submitted as a model input.
## Testing
- Cover app-server media conversion, unsupported-input placeholders, TUI omission, and tool-output truncation.
GitOrigin-RevId: 16152bf3af674575ce569764a8b472e032e7569d
## Why
Opening the agent picker stopped after adding status history whenever path-backed subagents were present, so those agents could not be selected from the picker.
## What changed
- Continue into the picker after rendering status for path-backed subagents.
- Skip duplicate liveness refreshes for path-backed threads and display non-primary agents by their canonical path when available.
## Testing
- Add a snapshot test that opens the picker for a path-backed agent and verifies that selecting it emits `SelectAgentThread` for the expected thread.
GitOrigin-RevId: 1668bb7817ce4e13c91d85c4d7ddab31c04c97b3
## Why
Opening the agent picker could clear a successful spawn hint before the new
sub-agent had emitted a turn event, making a running agent appear stopped.
## What changed
- Treat active turns and matching completion events as authoritative liveness
transitions while leaving an empty event store unchanged.
- Remember terminal liveness so delayed activity cannot revive a stopped agent;
only a new turn can mark it running again.
- Ignore `Interacted` activity when deriving agent liveness.
## Testing
Added coverage for empty stores, stale and current completion events, completed
snapshots, delayed activity, and subsequent turns.
GitOrigin-RevId: 462539d8134a5d3520dbd41edb44b3251f50ead5
## Why
Reverse search fetched persistent history one entry at a time, making a deep or unsuccessful search require a lookup for every older entry.
## What changed
- Keep the newest-entry probe lightweight, then scan older persistent history in bounded batches.
- Cache batch results by absolute offset and preserve continuation cursors across repeated searches.
- Ignore stale responses, retry failed batch reads a bounded number of times, and restore the draft without reporting a false “no match” state when history is unavailable.
## Testing
- Cover batch continuation, caching after query changes or cancellation, stale metadata, retry exhaustion, and thread routing.
- Verify that scanning 1,024 entries uses one single-entry lookup and eight batch lookups.
GitOrigin-RevId: efc791fcbd5290050af703dd31c5c21b33240e23
## Why
The Desktop app can use Codex or ChatGPT branding while retaining stable platform identities. CLI discovery and TUI handoff should not depend on a single display name or hardcoded executable path.
## What changed
- On macOS, search for both `ChatGPT.app` and `Codex.app`, and accept only bundles with the `com.openai.codex` identifier.
- On Windows, detect installs by their package app ID and resolve the `codex` protocol executable from the AppX manifest before handing off a TUI session.
- Use “Desktop app” consistently in CLI and TUI user-facing text.
## Testing
Add coverage for selecting a ChatGPT-named Codex bundle and rejecting the classic ChatGPT bundle.
GitOrigin-RevId: b84a56eb6e960712152e1a9b023ab530ec9a354a
## What changed
- Add nullable `mustShowInstallationInterstitial` metadata to app-server
`PluginSummary` responses.
- Preserve the remote service value through catalog, installed-plugin cache,
list, read, and share-list paths.
- Return `null` for local plugins and remote responses that omit the field so
clients can fail closed when the policy is unavailable.
## Testing
- Cover `true`, `false`, and missing values across remote summary paths and
app-server plugin endpoints.
GitOrigin-RevId: db79702ee2bfa800a9910d64d933bcabecb3ce70
## What changed
- Add the `SessionEnd` hook event to hook configuration, protocol schemas, analytics, and the hooks browser.
- Run matching hooks for root threads during shutdown, including app-server archive, delete, idle unload, and graceful shutdown. Flush the transcript first and provide the session ID, transcript path, working directory, and `reason: "other"`.
- Keep teardown bounded: hook output is advisory, the default timeout is one second, configured timeouts are capped at three seconds, and async hooks run synchronously with a warning.
## Testing
- Cover transcript availability, matcher selection, timeout normalization, ignored control output, subagent exclusion, archive/delete ordering, and graceful shutdown of multiple loaded threads.
GitOrigin-RevId: 5d19a658677a137caf836ed5042dcb43f5eb6d1a
## Why
The TUI import request used the selected migration source as the identifier for
the product initiating the import, conflating two distinct protocol fields.
## What changed
Set `source` to `cli` for imports initiated by the TUI while continuing to pass
the selected adapter through `migrationSource`.
GitOrigin-RevId: 7b00728464cb1d4e478ac4aa6b18f7254d2e5152
## What changed
Remove the unused `PairProgramming` and `Execute` footer indicator variants and their label and styling branches. Keep `Plan` as the only `CollaborationModeIndicator` rendered by the TUI.
GitOrigin-RevId: 5f3e6c8ff50a04d41dd5fc342cf1347a7e4f78fe
## What changed
Remove `word_wrap_lines_borrowed` and use the general `word_wrap_lines` API for
borrowed line slices. Drop the duplicate helper-specific tests while retaining
coverage of borrowed iterator wrapping through the general API.
GitOrigin-RevId: aa55a6180705a676bf82ea66c9ba0fe15d00a5fe
## Why
Selecting a usage-limit reset from the picker immediately started redemption,
leaving no opportunity to verify the choice.
## What changed
- Open a separate confirmation popup before redeeming a selected reset, with
`No, go back` selected by default.
- Show backend-provided reset titles and descriptions in the picker and
confirmation, with generic fallback copy when those details are absent.
- Ignore duplicate or stale confirmation and redemption events, while retaining
the idempotency key needed to retry a failed redemption.
## Testing
- Added coverage for confirmation, cancellation, backend copy, duplicate and
stale events, successful redemption, and retry behavior.
GitOrigin-RevId: 828945f99f06e8c73941fd864e4aa9ac52729f98
## Why
Multi-agent V2 spawned threads are controlled by their parent and reject direct
app-server input. The TUI should expose that ownership instead of presenting an
input flow that the server will reject.
## What changed
- Add the experimental `Thread.canAcceptDirectInput` capability for loaded
threads and populate it from the same policy used to validate `turn/start`
and `turn/steer`. Stored, unloaded threads report `null`.
- Carry the capability through TUI thread discovery, selection, startup, and
resume flows, with a compatibility fallback for older app servers.
- Present parent-owned threads as view-only, preserve drafts and queued input,
block agent-directed commands and settings shortcuts, and keep local
navigation and inspection commands available.
## Testing
- Cover V1 writable and V2 view-only spawned threads through selection and
resume.
- Cover composer submission paths, queued and initial input preservation,
allowed navigation commands, settings shortcuts, and the view-only UI.
GitOrigin-RevId: 495ad051249e5577fb0b0c1cc8c40a0998d04918
## What changed
Give command, permissions, patch, and MCP elicitation approvals dedicated
request structs, and update TUI routing and rendering to use the wrapped
payloads.
GitOrigin-RevId: ffee4058dd27505be2a11de3758ac12bb707b6b8
## What changed
- Apply `agents.default_subagent_model` and
`agents.default_subagent_reasoning_effort` when a spawn request does not
provide explicit values, including agent job workers.
- Allow full-history forks to use configured defaults or explicit model and
reasoning-effort overrides while retaining the parent conversation context.
- Preserve the selected model and reasoning effort when an agent role does not
override them.
## Testing
- Cover configured defaults, explicit override precedence, full-history forks,
role application, and agent job workers.
GitOrigin-RevId: b1efa8c9abeee82355088fceef57560433144595
## Why
The `agent_type` argument is only useful when agent roles are configured. Avoid
advertising an inapplicable override in the model-visible `spawn_agent` schema.
## What changed
- Include `agent_type` in the V1 and V2 spawn tools only when configured roles
are available.
- Clarify that `agent_type` is an explicit override and document its interaction
with context forking.
- Remove the unused `agents.support_agent_type` configuration field.
## Testing
- Add coverage for hiding `agent_type` without roles and exposing it when a role
is configured.
GitOrigin-RevId: 32e0f123b15f317e9cdb71774029375bc073d9ad
## What changed
- Add `agents.enabled` as a user override for multi-agent tools while keeping an enabled `features.multi_agent_v2` authoritative.
- Rename the shared spawned-thread limit to `agents.max_concurrent_threads_per_session`, retain `agents.max_threads` as an alias, and apply the setting to both multi-agent backends.
- Add reserved subagent model, reasoning effort, and agent-type settings to the config surface and persist all resolved agent settings in config locks.
- Show the resolved `[agents]` values in TUI debug-config output.
## Testing
- Cover config loading, legacy alias normalization across merged layers, backend-selection precedence, V2 concurrency, and debug output.
GitOrigin-RevId: 2957c954a2e1aef51592768dbbccd56c4bf8f118
## What changed
- Parse `cache_write_tokens` from response input token details and carry it through token usage aggregation.
- Expose `cache_write_input_tokens` in protocol, app-server, exec, and TypeScript SDK usage events, defaulting it to zero for compatibility with older payloads.
- Report cache-write usage in analytics, metrics, traces, and rollout data alongside existing cache-read usage.
## Testing
- Add coverage for response parsing, usage event output, aggregation, analytics, metrics, and telemetry fields.
GitOrigin-RevId: 634e4fbe3086a8923c0ee13b622573e7d9d221bd
## What changed
- Detect and import supported Cursor settings, sandbox permissions, MCP servers,
project instructions, hooks, agents, commands, plugins, and recent chat
sessions.
- Update the `/import` flow to check Claude Code and Cursor, prompting for a
source when both have importable data.
- Add `migrationSource` to the app-server detect and import requests so each
operation uses the selected adapter, while retaining `source` for import
attribution and backwards compatibility.
## Testing
- Add coverage for Cursor config conversion, hooks, plugins, session discovery
and conversion, app-server imports, and TUI source selection.
GitOrigin-RevId: a65a1511b6c1c2f9e3e0cfe4f816bb435807282e
## Why
Starting a user turn can wait on remote work. Show the submitted prompt immediately instead of leaving the input invisible during that wait.
## What changed
- Queue optimistic prompt history before app-event submissions and render a frame before starting the turn.
- Preserve the existing submit-failure behavior for direct submissions.
## Testing
- Verify that an initial prompt is added to history before its user-turn event is submitted during session replay.
GitOrigin-RevId: 57f30c6e0067127e6b082a206f7d154fcfef8d7d
## What changed
- Allow `thread/start` to select experimental `historyMode: "paginated"` when the thread store supports turn and item pagination.
- Resume paginated threads with bounded model context and require `excludeTurns: true` instead of loading full history.
- Return `turnsBackwardsCursor` and `itemsBackwardsCursor` from `thread/resume` so clients can hydrate durable history through `thread/turns/list` and `thread/items/list` while newer records arrive through live notifications.
- Reject operations that still require full history, including `initialTurnsPage`, `thread/read` with `includeTurns: true`, `thread/rollback`, and detached review.
- Make item cursors independent of the optional `turnId` filter.
## Testing
- Cover paginated thread start, cold and live resume, backwards cursor hydration, metadata reads, unsupported operations, and stores without pagination support.
GitOrigin-RevId: c42f9b268e29d049843330f474fa3ecde12f5b8a
## What changed
- Track connected and disconnected states across initial remote exec-server connections and reconnection attempts.
- Emit experimental `thread/environment/connected` and `thread/environment/disconnected` app-server notifications for each thread selecting the environment. Each payload identifies the thread and environment; current state is not replayed when a thread starts.
- Stop forwarding connection events when an environment selection is removed or replaced.
## Testing
- Cover connection, disconnection, reconnection, shared-environment notifications, and replacement of a selected environment.
GitOrigin-RevId: 5dd767372363c4a2a8319fc16164be117d5bd20c
## Why
Tabs in composer text could render at a different width from the cursor and
wrapping calculations, causing misaligned cursors and unexpected line breaks.
## What changed
- Replace tabs with single-column spaces for wrapping and rendering while
preserving the original editable text and byte ranges.
- Apply the same display representation to base text, styled elements, and
highlighted ranges.
## Testing
Add coverage for cursor alignment, rendered output, and wrapping of text that
contains tabs.
GitOrigin-RevId: 06d8489621d2f8b0823c7a004079d152dd0cab66
## What changed
- Use `$`-mention boundary rules when deciding whether a skill mention followed by a suffix is already bound.
- Fall back to the editable skill token on the left when the token on the right is a bound mention such as `$bound/path` or `$bound.config`.
## Testing
- Add completion-target coverage for path and configuration suffixes.
- Add a composer snapshot covering the skill popup fallback for a bound path suffix.
GitOrigin-RevId: bf72237dfd56cfe6f590a3fab10c2bfe03b088a8
## Why
Skill mentions and shell parameters both use a `$` prefix. Numeric and special
shell parameters should not open or displace completion popups, while loaded
skills can legitimately have digit- or hyphen-leading names.
## What changed
- Classify `$` queries as skill candidates, shell variables, definite shell
parameters, or ambiguous shell-like names.
- Offer completion for an ambiguous name only when it fuzzy-matches a bindable
loaded mention, reusing the filtered catalog when the popup opens.
- Keep definite shell forms such as `$1`, `$12`, `$-`, and `$_` out of mention
completion and preserve completion targets elsewhere in the composer.
## Testing
Added unit and snapshot coverage for positional and special parameters,
digit- and hyphen-leading skills, uppercase shell variables, unbindable
qualified skills, and competing completion targets.
GitOrigin-RevId: 8bb64cb5ca0fa8233c7fadb11a53678d57eb814c
## What changed
- Add experimental `beforeTurnId` support to `thread/fork` for copying history strictly before a turn, including an in-progress turn.
- Use before-turn forks for TUI backtracking and safety retries so the replacement prompt retains thread context instead of recreating the branch from the preceding turn or a new thread.
- Add experimental `deferGoalContinuation` support so safety-retry forks can inherit an active goal while waiting for the replacement turn before automatic continuation resumes.
- Hide duplicated nested-review prompts when replaying history or selecting a prompt to edit.
## Testing
- Cover before-turn truncation, fork validation, active-goal inheritance, TUI safety retries, backtracking, and nested-review replay.
GitOrigin-RevId: 4915d85ae1929a0b8c40f3ed7dca29c7a5bdcdf3
## Why
Retrying a safety-buffered turn by rolling back the active thread rewrites the
source conversation and requires the TUI to repair its local transcript state.
## What changed
- Interrupt the buffered turn, then fork after the preceding completed turn and
submit the prompt on the new thread with the faster model and low reasoning
effort.
- Start a new thread when the buffered request is the conversation's first turn.
- Preserve committed steering input in the retry, leave the source thread
intact, and restore the prompt alongside any existing draft if branching
fails.
- Do not offer the retry action for side conversations or stale and in-progress
turns.
## Testing
Added coverage for retries with prior context, first-turn retries, committed
steering input, branch failures, existing composer drafts and attachments, and
side conversations.
GitOrigin-RevId: adb49da8236e9212ef0082e033e6f715986b5cd9
## What changed
- Add an explicit restore mode for thread input snapshots and use it when replaying thread snapshots.
- Preserve the pending-steer interrupt flag alongside running-turn and queued-input state when restoring an in-flight turn.
- When in-flight state is not preserved, clear stale running flags and move pending steers ahead of already queued follow-ups while retaining their history records.
## Testing
- Expand TUI tests to cover both restoration modes, including sleep-inhibitor state, pending-steer ordering, history records, and queued submission.
GitOrigin-RevId: f4e8b2bdf065ef6c6644b7f0ea9cf32c8a9af619
## What changed
- Fork the conversation immediately before the selected prompt instead of rolling back the current thread in place, preserving the original conversation.
- Reopen the selected prompt in the new conversation with its images, text elements, and mention bindings intact.
- Start a fresh conversation when editing the first prompt, show a dedicated continuation notice, and restore the prompt with an error if branching fails.
## Testing
- Cover branching before first and later prompts, source preservation, prompt restoration, hidden review prompts, mid-turn steering, in-progress turns, stale transcript entries, and mention bindings.
GitOrigin-RevId: 15473535b3f9733b0300711a498969e6d389db79
## What changed
- Leave an output-free interrupted prompt in the transcript and open a blank
composer for the user's next instruction.
- Use the normal interruption notice for both `Esc` and `Ctrl-C` interrupts.
- Track safety-buffering prompts separately so failed retries can still restore
the prompt, including after switching between threads.
## Testing
- Cover output-free `Esc` and `Ctrl-C` interrupts, failed safety-buffer retries,
and restoration of safety-buffer state from thread snapshots.
GitOrigin-RevId: 30b368d00dfdb981d06d4c95ce3f252389b7917c
## Why
Sparse and out-of-order rate-limit updates can omit account metadata or let an
older full read overwrite a newer workspace hard stop. Credit availability also
does not always include a displayable balance.
## What changed
- Propagate the backend's `spendControlReached` state through rate-limit
snapshots and the app-server protocol, preserving it across sparse updates.
- Keep workspace hard-stop classifications for error routing and ignore stale
full-read results after a newer hard-stop notification.
- Base TUI warnings and model-switch prompts on credit availability and hard-stop
state, and show `Credits: Available` when a finite balance is hidden.
## Testing
Added coverage for spend-control mapping, snapshot merging, out-of-order reads,
workspace error routing, warning and prompt behavior, and credit status display.
GitOrigin-RevId: 18b09d493d5a620a7c079fb721ec50b38dd5b04c
## What changed
- Add `subErrorType` to external agent config import failures and carry it through progress and completion notifications, persisted import histories, and analytics.
- Expose plugin store failure subtypes from `PluginInstallError` so manual installs and imported plugins report details such as `failed_to_copy_plugin_file` while failures without a subtype remain `null`.
- Keep existing persisted import records compatible by defaulting the new field when it is absent.
## Testing
- Cover store I/O subtype extraction, analytics serialization, persisted import histories, and migration notification fixtures.
GitOrigin-RevId: ec1a85623fc826cbd7cfe9f55c2dd2bc86665937
## What changed
- Hide `gpt-5.4` and `gpt-5.4-mini` from model selection and direct existing users to `gpt-5.6-terra` and `gpt-5.6-luna`, respectively.
- Use Terra for memory consolidation and Luna for memory extraction and rate-limit switch prompts.
- Keep Amazon Bedrock GPT-5 catalog entries visible when their bundled model metadata is hidden.
## Testing
- Add coverage that all Amazon Bedrock GPT-5 models remain visible and update TUI expectations for the new model choices.
GitOrigin-RevId: fd69c8d5fb6b510c77204df6b7ac3f07e67cded2
## What changed
- Define `SleepItem` in `codex-extension-items` and carry `clock.sleep` events through `TurnItem::Extension`.
- Preserve sleep persistence, thread-history reconstruction, and the app-server's `type: "sleep"` schema while reusing the extension-owned type.
## Testing
- Add serialization coverage for the `clock.sleep` extension wire shape and its protocol wrapper.
- Update sleep lifecycle and thread-history tests to exercise the extension-owned item.
GitOrigin-RevId: 34bb33ed9b90a09bf4744aafdb56e019c717a168
## Why
Special filesystem subpaths can contain relative or foreign-platform path
spellings. Treating this wire text as a host-native path can reinterpret it.
## What changed
- Store special filesystem subpaths as strings in the core permissions model.
- Represent app-server subpaths as `LegacyAppPathString` and convert them at
the protocol boundary without changing their spelling.
- Add `LegacyAppPathString::from_string` for callers that already own legacy
app-server path text.
GitOrigin-RevId: 2214f03aa997fd0e6eb2ab60d425304bb4bd6132
## What changed
- Hide the working-status indicator when finalized assistant output is committed to the transcript, including single-line final answers.
- Restore the indicator when image generation begins during a running task after its streamed preamble has been flushed.
## Testing
- Add snapshot coverage for a single-line final answer and for image generation following a single-line preamble.
GitOrigin-RevId: e294a11cda3f0ce46f2bbed1be2a1380c9c73085
## Why
Stream consolidation can replace transcript cells while initial history replay is buffering capped display rows, leaving those rows stale and omitting the finalized output.
## What changed
- Discard buffered rows when required stream reflow occurs during capped initial replay and rebuild the capped tail from the canonical transcript after replay finishes.
- Schedule the rebuild through the resize reflow path so it waits for an active transcript overlay to close.
## Testing
Added coverage for consolidated Markdown output during capped initial replay, both with and without an active transcript overlay.
GitOrigin-RevId: 1c184ff561a50362daf11c1c629be59882f27a4a
## Why
Full access significantly increases the risk of data loss, leaks, or unexpected behavior, so users should explicitly confirm each time they select it.
## What changed
- Always open the full access confirmation when user-reviewed approvals are active, regardless of `notices.hide_full_access_warning`.
- Remove the persistent "don't ask again" option and its acknowledgement events.
## Testing
- Update the TUI permission tests and confirmation popup snapshot to cover repeated confirmation.
GitOrigin-RevId: 0ee827332441e13d9445349ed6a5a92dc8fef4b2
## Why
Clients that account for individual upstream Responses API calls need the exact
usage for each completion rather than accumulated or estimated thread usage.
## What changed
- Add the opt-in `rawResponse/completed` app-server notification with the
`threadId`, `turnId`, `responseId`, and upstream `usage` payload.
- Emit the transient event for normal turns and compaction requests when
`experimentalRawEvents` is enabled. The event is not persisted or replayed,
and `usage` is `null` when the upstream response omits it.
- Export the notification in the app-server schemas and document its behavior.
## Testing
- Cover exact token breakdowns for turn and compaction completions.
GitOrigin-RevId: 49040a060bf1784c1ff1dd62112efb4a778428c4
## What changed
- Include the active Codex Apps tools cache and connector directory cache, when available, in diagnostic uploads that include logs.
- Resolve cache paths from the current authentication context and use stable attachment filenames.
- List both optional cache files in the upload consent dialog.
## Testing
- Add coverage for selecting existing active cache files, including a directory cache without an account ID.
- Update consent dialog snapshots to include the optional attachments.
GitOrigin-RevId: 1d4ffbf2bcb96653f03dc25f91d80dd65038d585
## What changed
- Add an optional `source` selector to `externalAgentConfig/detect`, while preserving the existing behavior for omitted, `null`, and unrecognized values.
- Pass `claude-code` as the source for TUI detection and import requests.
- Move source-specific migration behavior behind an adapter boundary and consolidate session migration into `codex-external-agent-migration`.
## Testing
- Cover explicit, omitted, and unknown detection source values with app-server protocol tests.
- Add unit coverage for the extracted migration and hook helpers.
GitOrigin-RevId: 63bd3dcb485f3ad7bd996022db4e351506aeea77
## What changed
- Make `Esc` dismiss the slash-command popup immediately without changing the draft or interrupting a running task.
- Keep the popup closed while the first-line command token is unchanged, and reopen it after the token is edited.
## Testing
- Cover dismissal while idle and while a task is running.
- Add a snapshot confirming that the dismissed popup remains hidden.
GitOrigin-RevId: f0ee84af080181e8d92c435f474ded1c8cb5b457
## Why
Model overrides for `spawn_agent` must be compatible with the multi-agent backend used by the current turn.
## What changed
- Carry each model's multi-agent backend metadata into `ModelPreset`.
- Filter the advertised `spawn_agent` model overrides for multi-agent v2 and reject overrides assigned to another backend.
- Limit error suggestions to picker-visible, backend-compatible models.
## Testing
Added coverage for hiding incompatible models from the tool description and rejecting them during spawn validation.
GitOrigin-RevId: 22c12aba67df46e9743a74f019b72a1b8b76b308
## Why
`Max` and `Ultra` consume usage limits faster than standard reasoning levels, so they should not be selected accidentally while navigating the normal effort scale.
## What changed
- Move `Max` and `Ultra` behind a `More reasoning…` entry with a dedicated warning and descriptions.
- Keep the reasoning shortcuts from silently increasing into advanced efforts.
- Apply `Ultra` to the active conversation without changing defaults for new threads, while preserving it across mode switches and thread resumes.
- Record applied thread settings in thread metadata, including explicit clearing of reasoning effort, so resumed threads restore their latest model settings unless the user supplied an override.
## Testing
- Add TUI coverage for the advanced picker, shortcuts, Plan mode, configuration defaults, and resumed conversations.
- Add app-server and thread-store coverage for persisting, clearing, and restoring model and reasoning settings.
GitOrigin-RevId: 6708c7c2e8d38f491bf63000ea34f83476afdfe6
## What changed
- Resolve `@` and `$` completion targets on either side of the cursor while treating atomic text elements and line breaks as boundaries.
- Prefer the nearest editable mention when file, skill, and plugin candidates compete, and avoid treating common uppercase environment variables as skill queries.
- Insert a separator before completions adjacent to atomic elements and keep dismissed popup state scoped to the matching editable token occurrence.
## Testing
- Add unit and snapshot coverage for adjacent and partially bound mentions, whitespace boundaries, shell variables, popup dismissal, and file, image, skill, and plugin insertion.

## Why
The skill toggle view truncated every display name to 21 characters, even when
the popup had enough room to show more. This could hide the part that
distinguishes similarly named skills.
## What changed
- Pass full skill display names to the shared row renderer so it can fit them
to the available width alongside descriptions.
- Keep narrow layouts bounded by the renderer's width-aware truncation.
## Testing
Added coverage for preserving and filtering full display names, plus snapshots
for wide and narrow popup layouts.

## What changed
- Replace tab characters in rendered diff spans with four spaces while keeping
their wrapping width and style intact.
- Ensure diff buffers never contain literal tab characters.
## Testing
- Cover tab expansion and wrapping in `wrap_styled_spans`.
- Update diff gallery snapshots at multiple terminal sizes.
