## Why
Losing an external app-server connection can leave a submission's outcome uncertain. The TUI must preserve local work without retrying it or allowing stale server events to trigger more actions.
## What changed
- Enter an offline state when an external app-server transport disconnects during startup, event streaming, or submission.
- Keep conversation drafts, queued input, expanded pastes, attachments, and agent-overview input editable while blocking submissions, remote actions, and automatic queue replay.
- Show a connection-lost notice that directs users to copy their work and relaunch, while retaining `Ctrl-C` and an empty-composer `Ctrl-D` as quit shortcuts.
- Cancel pending views and asynchronous work, and ignore stale completions after the disconnect. Embedded app-server behavior is unchanged.
## Testing
Added unit, snapshot, and pseudo-terminal coverage for lost startup and mutation replies, offline draft editing, queued-input recovery, stale-event quarantine, agent-overview behavior, and end-to-end preservation without reconnection or resubmission.
GitOrigin-RevId: 7219a95fad676dda447d625db9e465345b469d58
## What changed
- Carry optional backend-owned banner and account identity data through
`account/rateLimits/read`, filtering banners that do not match the authenticated
account and user.
- Render supported rate-limit notices above the composer with actions for usage,
credits, resets, owner notifications, and plan management while preserving the
existing fallback UI for absent or unsupported banners.
- Refresh usage after limit errors, reject stale responses, and keep queued input
paused until recovery completes. When instructed by the banner, switch to the
first available fallback model without changing unrelated thread settings.
## Testing
- Add protocol, banner parsing and rendering, CTA, identity filtering, refresh
ordering, fallback-model, account-change, and queued-input recovery coverage.
GitOrigin-RevId: e03d75a82e425deb87f4b120a71cf2286c0ef6cc
## What changed
- Ignore `thread/started` notifications for ephemeral threads whose feature source is `system`, preventing hidden helper threads from entering TUI thread routing or refreshing the agents overview.
- Continue routing persisted system threads normally.
## Testing
- Add coverage for hidden and persisted system-thread notifications in the agents overview.
- Add generated-title normalization cases for wrapping quotes, trailing punctuation, and meaningful leading punctuation.
GitOrigin-RevId: e1ea48502b4f9aa7d5a187c7407df69c55abe2a9
## 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.
GitOrigin-RevId: 7ed73522f4f6c65a005f65f3a903974d8419e312
## What changed
- Include matching Codex tasks in the `@` mention popup when the active thread supports task tools, prioritizing tasks from the current working directory.
- Submit selected tasks as bounded live thread references so Codex can load their contents with `read_thread`.
- Preserve task mentions across composer history and thread start, resume, and fork flows.
## Testing
- Add coverage for task search and capability propagation, popup selection and rendering, submission encoding, history round-trips, and reference validation and limits.
GitOrigin-RevId: 17502be91bf6d4b01745668829eb69fb318cb5b9
## Why
The TUI rejected app-server dynamic tool calls as unsupported, so agents could
not inspect or manage other Codex tasks through a TUI session.
## What changed
- Add the `codex_tui` tool namespace for listing, reading, waiting on, creating,
forking, messaging, renaming, archiving, and restoring tasks.
- Handle tool calls through existing app-server thread operations, with bounded
inputs and responses and cleanup when calls complete or the TUI disconnects.
- Route delegation tools through an authenticated local MCP server with explicit
approval prompts, while respecting configured and managed MCP policies.
- Fall back to starting threads without dynamic tools when connected to an older
app server that does not support them.
## Testing
Add coverage for tool schemas and response bounds, task lifecycle operations,
approval-gated MCP transport, namespace dispatch, cancellation, and legacy
app-server fallback behavior.
GitOrigin-RevId: c782c11f0a3edceb3fa6909a4b92d6ce01a6eed3
## Why
Approval and item IDs can collide across concurrent threads. Tracking pending app-server approvals by ID alone can therefore resolve, submit, or dismiss a request from the wrong thread.
## What changed
- Key command execution, file change, and permissions approvals by both thread ID and approval ID.
- Route approval responses through the originating thread and require the thread to match when processing resolution notifications or dismissing approval prompts.
- Canonicalize parseable thread IDs so equivalent UUID representations still match.
## Testing
- Cover colliding approval IDs across threads, mismatched resolution notifications, prompt dismissal, and response routing for primary and background threads.
GitOrigin-RevId: c2d899a1e4b6a6413c78a0595a5311f5fabb9815
## What changed
- Let users start tasks, open root sessions, rename tasks, and stop active work directly from the agents overview.
- Show details for the selected task on wide terminals and limit the overview to root sessions while still reflecting background activity.
- Preserve draft input and pending server requests when switching sessions so running roots and their subagents can continue in the background.
- Apply the selected project's working directory when dispatching from project grouping, including remote workspaces.
## Testing
- Expand overview rendering and interaction coverage for root filtering, dispatch, search, selection, renaming, and responsive input.
- Cover switching away from roots with running subagents and retaining background server requests.
GitOrigin-RevId: b7b0d33b7ecc077498efb756a0ad2fd425158b17
## What changed
- Add `/agents` to open a full-screen dashboard of loaded root sessions from the shared app server, with subagent status reflected in each root session.
- Support search, navigation, and grouping sessions by project or status.
- Refresh the dashboard when relevant thread notifications arrive, while preserving its selection and view preferences.
- Show a clear message when the dashboard is unavailable with the embedded app server.
## Testing
- Add coverage for dashboard rendering, status grouping, persisted view state, and restoring the conversation viewport after closing the dashboard.
- Cover `/agents` command discovery and dispatch from parent-owned threads.
GitOrigin-RevId: 6651f4c47358116e1809da3ac8844a5842026a95
## What changed
- Use `/subagents` consistently for the subagent picker and status UI, removing the `/agent` alias.
- Rejoin already-loaded subagent threads without overriding their existing settings.
- Route notifications and approval requests only to the active thread or its known subagents, discard unrelated startup events, and avoid replaying resolved approvals.
## Testing
- Add coverage for filtering buffered startup events, dropping resolved approvals, preserving owned subagent approvals, and resuming threads without setting overrides.
GitOrigin-RevId: b4e597f7cd4756faccf31d8b964e7a172f5ab0eb
## Why
App directory data and in-flight requests can outlive the account, workspace, or thread that produced them, allowing stale apps to appear in the current TUI context.
## What changed
- Invalidate cached app data, dismiss the app picker, and start a fresh fetch when the account, workspace, or thread changes.
- Tag app directory fetches with their originating thread, workspace, and scope generation, and ignore queued requests or results that no longer match.
- Treat `AppListUpdated` notifications as revalidation signals instead of directly adopting their unscoped contents, with deduplication and a bounded error retry.
## Testing
Added coverage for stale request and result rejection, context invalidation, picker dismissal, and notification revalidation.
GitOrigin-RevId: f20930a0598a6abbdfb3c7826ec955346fe2da7a
## Why
Configuration and app-server initialization can take time before the main TUI is ready, leaving users unable to begin drafting a prompt.
## What changed
- Show a provisional composer while startup work runs and carry its text, cursor position, paste state, and attachments into the initialized chat.
- Limit the provisional composer to safe editing and cancellation, and quarantine input around session pickers, approvals, and other actionable startup screens.
- Preserve configuration validation before terminal checks and recover terminal state cleanly from startup failures and caught panics.
## Testing
- Cover startup editing, multiline and large pastes, keymaps, cancellation, session-picker handoff, approval boundaries, and draft restoration.
- Verify non-interactive launches report configuration errors before terminal errors.
GitOrigin-RevId: fe04a85cfbbcff21ff87fa81fd17474827858575
## What changed
- Extend `account/usage/read` with an optional `threadId` request and a
backward-compatible `threadUsage` response containing estimated credits,
optional USD cost, and model, reasoning, speed, and token breakdowns.
- Fetch thread usage for eligible Business and Enterprise plans when `/status`
is opened, then update the rendered status card asynchronously.
- Preserve terminal scrollback when replacing a visible status-card tail, and
append a refreshed card when the original tail can no longer be updated.
## Testing
- Add app-server coverage for authentication, canonical thread IDs,
unavailable billing routes, and malformed IDs.
- Add TUI coverage for usage formatting, stale responses, retries, history
updates, terminal reflow, and scrollback preservation.
GitOrigin-RevId: 49300914b3fba917c0f08e8595363e04e5ba6d37
## Why
Subagents can leave cached MCP servers deferred indefinitely, causing the TUI to keep showing MCP startup as running after every server that reported startup has settled.
## What changed
- Clear configured MCP startup expectations for active subagent threads so their status is driven by actual startup notifications.
- Preserve configured-server startup tracking for primary threads and side conversations.
## Testing
Add coverage for active and resumed subagents with deferred servers, plus the existing side-conversation behavior.
GitOrigin-RevId: 4d929a162dd067b4a76351652a764a79ce60f31f
## What changed
- Move the migration flow, model, and source picker under the
`external_agent_config_migration` module.
- Keep their tests and snapshots alongside the corresponding module files and
update imports and snapshot source paths.
GitOrigin-RevId: 4b2f83ca689534e4d9cd1dc7aaa8424e76166bba
## Why
Switching away from a side conversation should not wait for its interrupt and
unsubscribe requests to finish.
## What changed
- Remove a side conversation from local TUI state immediately when switching
threads, then interrupt and unsubscribe it in a background task.
- Retry interruption with the active turn ID when the original turn races with
cleanup.
- Ignore late notifications and reject server requests for abandoned side
conversations.
## Testing
- Added coverage that background cleanup removes local state and ignores late
events and approval requests.
GitOrigin-RevId: 7a1d1c34f16ab023d1d1e235451b55404731190c
## What changed
- Store `ServerNotification` and `ServerRequest` payloads behind `Box` in
`AppServerEvent`, `InProcessServerEvent`, and TUI `ThreadBufferedEvent` values.
- Update app-server delivery, TUI routing and replay, exec, onboarding, and tests
to borrow or consume the boxed payloads as appropriate.
GitOrigin-RevId: 7d0dab9aba47487114128ce55c914af5bb46c5b5
## 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
- Show per-type import counts in the `/import` review UI and started
message.
- Render completion results as a multi-line summary with total
imported/failed counts and one row per import type.
- Add snapshot coverage for the updated review and completion output.

/>
## Why
The TUI previously only reported that Claude Code import started or
finished. Users could not see how many items of each type were selected
or how many actually imported versus failed.
## Why
Connector metadata is consumed by connector discovery, ChatGPT
integration, core, and TUI code. Treating app-server's wire DTO as the
shared domain model reverses the intended dependency direction.
## What changed
- Added connector-owned app branding, review, screenshot, metadata, and
info types.
- Added explicit conversions in app-server and TUI while preserving
app-server's wire payloads.
- Removed production app-server-protocol dependencies from connectors
and ChatGPT connector code.
## Stack
This is PR 4 of 6, stacked on [PR
#29722](https://github.com/openai/codex/pull/29722). Review only the
delta from `codex/split-config-layer-types`. Next: [PR
#29724](https://github.com/openai/codex/pull/29724).
## Validation
- Connector and tools coverage passed.
- App-server app-list coverage passed: 13 tests.
## Why
[#25345](https://github.com/openai/codex/pull/25345) was approved,
green, and squash-merged into its stacked base branch,
`fcoury/tokenmaxxing-api`. Four minutes later, that base branch was
force-pushed back to an API-only rebased head while preparing
[#25344](https://github.com/openai/codex/pull/25344) for `main`. As a
result, the squash commit from #25345 was orphaned and the TUI command
never reached `main` or a release.
This PR relands the orphaned TUI change from
[`411410b8`](https://github.com/openai/codex/commit/411410b85c2d8eb050d441f17396c5c4048d866f)
on current `main`.
## What changed
- Add `/usage`, `/usage daily`, `/usage weekly`, and `/usage cumulative`
for account token activity.
- Fetch account usage asynchronously through the existing
`account/usage/read` app-server RPC.
- Render daily, weekly, and cumulative activity with theme-aware
terminal palettes and bounded transient cards.
- Preserve transcript ordering while assistant streams, history
consolidations, active cells, and hooks complete.
- Hide `/usage` from completion when backend auth is unavailable while
keeping typed-command guidance.
- Carry current-main behavior forward for cwd-aware Markdown parsing,
Windows Terminal color detection, and personal access token auth.
- Clear pending usage cards on thread rollback and delay completed cards
until live hook output is committed.
- Add focused regression and snapshot coverage for loading, auth errors,
invalid views, rollback, hook ordering, layout, and charts.
## Prior review
The original implementation was approved by Eric Traut in #25345 after
testing multiple themes and light/dark terminals. This PR preserves that
reviewed implementation while adapting it to current `main` and adding
regression coverage for newer rollback and hook lifecycle behavior.
## Validation
- `just test -p codex-tui token_activity palette renderable
usage_command` — 37 passed.
- Focused rollback, hook-ordering, and error snapshot tests — 4 passed.
- `just fix -p codex-tui` — passed.
- `UV_CACHE_DIR=/private/tmp/codex-uv-cache just fmt` — passed.
- `cargo insta pending-snapshots` — no pending snapshots.
- `just test -p codex-tui` — 2,870 passed; two unrelated guardian
feature-flag tests failed because their expected `OverrideTurnContext`
event was absent:
-
`update_feature_flags_disabling_guardian_clears_manual_review_policy_without_history`
-
`update_feature_flags_disabling_guardian_clears_review_policy_and_restores_default`
- `just argument-comment-lint` could not complete because the local
Bazel LLVM `compiler-rt` repository is missing `include/sanitizer/*.h`.
The touched Rust diff was manually inspected and no missing
opaque-literal argument comments were found.
## Why
External-agent import should be discoverable and deliberate without
blocking startup or claiming the public `codex [PROMPT]` CLI namespace.
The slash command keeps the flow local to the interactive TUI and reuses
the existing app-server import API.
## What changed
- add the user-facing `/import` slash command
- detect external-agent importable items only when the command is
invoked
- run imports through the embedded local app-server
- show start and completion messages, refresh configuration, and block
duplicate imports while one is pending
- reject the flow for unsupported remote and local-daemon sessions
## Validation
- `just test -p codex-tui external_agent_config_migration` (10 passed)
- manually exercised an isolated TUI fixture with existing
external-agent setup and session data using a fresh `CODEX_HOME`
- verified picker customization, plugin and session detection, import
completion, repeated invocation, and imported-session resume context
- the broader `just test -p codex-tui` run passed 2,805 tests, with 2
unrelated guardian feature-flag failures and 4 skipped tests
## Draft follow-ups
- review whether completion messaging should remain attached to the
initiating chat if the user switches chats during an import
- review shutdown semantics for an in-progress background import

## Why
MCP startup failures from spawned subagents were rendered as global
notifications, so a child thread's failure could pollute the visible
parent transcript. Routing the notification to the child exposed two
related replay problems: session refresh could discard the buffered
event, and a newly created child `ChatWidget` did not know the expected
MCP server set, which could leave its startup spinner running after
every server had settled.
MCP startup diagnostics should remain visible in the thread that owns
the startup without affecting other transcripts. The protocol also needs
to support a future app-scoped MCP lifecycle where startup is not owned
by any thread.
## Reported Behavior
The [originating Slack
report](https://openai.slack.com/archives/C08JZTV654K/p1780604538859939)
called out that using subagents could turn MCP startup failures into a
wall of yellow CLI warnings because repeated failures were not
deduplicated. The intended behavior is for those diagnostics to remain
visible once in the thread that owns the startup, without polluting the
parent transcript.
## What Changed
- add nullable `threadId` ownership to `mcpServer/startupStatus/updated`
- populate it from the app-server conversation ID for the current
thread-scoped lifecycle and regenerate the protocol schema and
TypeScript artifacts
- treat a missing or null `threadId` as app-scoped without injecting it
into the active chat transcript
- route and buffer thread-owned MCP startup notifications by thread in
the TUI
- preserve buffered MCP startup events across child session refresh
- seed expected MCP servers before replaying a thread snapshot so
startup reaches its terminal state
- suppress an identical repeated failure warning for the same server
within one startup round
The owning thread still renders the detailed failure and final `MCP
startup incomplete (...)` summary.
## How to Test
1. Configure an optional MCP server named `smoke` that exits during
initialization.
2. Launch the TUI with multi-agent support enabled.
3. Confirm the main thread's own startup failure renders one detailed
`smoke` warning and one incomplete-startup summary.
4. Spawn exactly one subagent.
5. Confirm the parent transcript does not receive the subagent's MCP
startup failure.
6. Switch to the subagent thread and confirm it contains exactly one
detailed `smoke` failure and one incomplete-startup summary.
7. Confirm the subagent's MCP startup spinner disappears and the thread
remains usable.
8. Switch between the parent and subagent and confirm the warnings
neither move nor duplicate.
Targeted tests:
- `just test -p codex-app-server-protocol`
- `just test -p codex-app-server
thread_start_emits_mcp_server_status_updated_notifications`
- `just test -p codex-tui mcp_startup`
The parent/child behavior and spinner completion were also exercised
manually in tmux. `just argument-comment-lint` was attempted but blocked
by an unrelated local Bazel LLVM empty-glob failure; touched Rust
callsites were inspected manually.
## Summary
- add v2 personal access token support for `codex login
--with-access-token` and `CODEX_ACCESS_TOKEN`
- classify opaque `at-` tokens separately from legacy Agent Identity
JWTs
- hydrate required ChatGPT account metadata through AuthAPI
`/v1/user-auth-credential/whoami`
- use PATs directly as bearer tokens while preserving existing ChatGPT
account surfaces
- expose PAT-backed auth as the explicit `personalAccessToken`
app-server auth mode
## Implementation
PAT auth is intentionally small and stateless. Loading a PAT performs
one AuthAPI metadata request, stores the hydrated metadata in the
in-memory auth object, and redacts the secret from debug output. Legacy
Agent Identity JWT handling remains unchanged. The shared access-token
classifier lives in a private neutral module because it dispatches
between both credential types.
PAT hydration fails closed when AuthAPI omits any required metadata,
including email. Hydrated metadata is intentionally not persisted:
startup performs a live `whoami` preflight so revoked tokens or changed
account metadata are not accepted from a stale cache.
## Workspace restriction scope
This change intentionally does **not** apply
`forced_chatgpt_workspace_id` to PAT authentication. The setting is a
client-side config guardrail, not an authorization boundary, and PAT
does not currently require workspace-ID parity. The PAT login and
`CODEX_ACCESS_TOKEN` paths therefore validate through AuthAPI without
threading workspace-restriction state through access-token loading.
Existing workspace checks for non-PAT auth remain on their established
paths.
## App-server compatibility
The public app-server `AuthMode` is shared across v1 and v2, and
PAT-backed auth reports `personalAccessToken` through both APIs.
Following human review, this intentionally removes the temporary v1
compatibility mapping that reported PATs as `chatgpt`; the deprecated v1
API is kept in parity with v2 rather than maintaining a separate closed
enum. Clients with exhaustive auth-mode handling in either API version
must add the new case and should generally treat it as ChatGPT-backed
unless they need PAT-specific behavior.
The v1 auth-status response still omits the raw PAT when `includeToken`
is requested because that response cannot carry the account metadata
needed to reuse the credential safely. Persisted PAT auth also omits the
new enum value so older Codex builds can deserialize `auth.json` and
infer PAT auth from the credential field after a rollback.

## Summary
Enterprise users can have an effective monthly credit limit, but Codex
`/status` currently drops that metadata from the account-usage response.
This change adds the optional `spend_control.individual_limit`
projection to the existing rate-limit snapshot flow. The backend client
reads the monthly limit, app-server exposes it as `individualLimit`, and
the TUI renders a `Monthly credit limit` row through the existing
progress-bar renderer.
When the backend does not return an effective monthly limit, existing
rate-limit behavior is unchanged.
## Existing backend state
The account-usage backend already returns the effective monthly limit
and current usage together:
```json
{
"spend_control": {
"reached": false,
"individual_limit": {
"limit": "25000",
"used": "8000",
"remaining": "17000",
"used_percent": 32,
"remaining_percent": 68,
"reset_after_seconds": 86400,
"reset_at": 1778137680
}
}
}
```
Before this change, Codex projected rolling `primary` and `secondary`
windows plus `credits`. It ignored `spend_control.individual_limit`, so
app-server clients and `/status` could not render the monthly cap.
The updated flow is:
```text
account usage backend
-> backend-client reads spend_control.individual_limit
-> existing rate-limit snapshot carries optional individual_limit
-> app-server exposes optional individualLimit
-> TUI renders Monthly credit limit
```
## App-server contract
`account/rateLimits/read` and sparse `account/rateLimits/updated`
notifications now include an additive nullable
`rateLimits.individualLimit` field:
```json
{
"individualLimit": {
"limit": "25000",
"used": "8000",
"remainingPercent": 68,
"resetsAt": 1778137680
}
}
```
In an `account/rateLimits/read` response, `null` means no monthly limit
is available. `account/rateLimits/updated` remains a sparse rolling
notification: clients merge available values into their most recent
`account/rateLimits/read` snapshot or refetch. Nullable account metadata
in a rolling notification does not clear a previously observed value.
## Design decisions
- Extend the existing rate-limit snapshot instead of introducing a
separate request or wire-level update protocol.
- Keep the Codex projection narrow: `/status` needs the effective limit,
current usage, remaining percentage, and reset timestamp.
- Render the monthly row through the existing progress-bar renderer,
with one optional detail line for `8,000 of 25,000 credits used`.
- Keep the backend response optional so existing accounts and older
usage states preserve their current behavior.
- Preserve cached monthly metadata when sparse rolling notifications
omit it. Live account-usage reads remain authoritative and can clear a
removed limit.
## Visual evidence
```text
Monthly credit limit: [██████████████░░░░░░] 68% left (resets 07:08 on 7 May)
8,000 of 25,000 credits used
```
Snapshot:
`codex-rs/tui/src/status/snapshots/codex_tui__status__tests__status_snapshot_includes_enterprise_monthly_credit_limit.snap`
## Testing
Tests: generated app-server schema verification, protocol tests,
backend-client tests, app-server integration coverage, TUI snapshot
coverage, formatting, and workspace lint cleanup.
## Why
App and skill toggles are user config mutations too. When the TUI is
attached to a remote app server, writing those toggles into the local
`config.toml` makes the UI report success without updating the server
that actually owns the session.
This is **[2 of 4]** in a stacked series that moves TUI-owned config
mutations onto app-server APIs.
## What changed
- Routed app enable/disable persistence through app-server config batch
writes.
- Routed skill enable/disable persistence through `skills/config/write`.
- Avoided refreshing local config from disk after these writes when the
TUI is connected to a remote app server.
## Config keys affected
- `apps.<app_id>.enabled`
- `apps.<app_id>.disabled_reason`
- `[[skills.config]]` entries keyed by `path`, with `enabled = false`
used for persisted disables
## Suggested manual validation
- Connect the TUI to a remote app server, disable an app, reconnect, and
confirm the app remains disabled from remote config rather than local
disk state.
- Re-enable the same app and confirm both `apps.<app_id>.enabled` and
`apps.<app_id>.disabled_reason` are cleared remotely.
- Disable a skill in the manage-skills UI and confirm a remote
`[[skills.config]]` disable entry appears.
- Re-enable that skill and confirm the disable entry is removed and the
effective enabled state updates without relying on local config reloads.

## Why
With the local model layer and app-server routing in place from PR1,
this PR moves the active TUI runtime onto app-server notifications. The
affected pieces share the same event flow, so the command surface,
session state, bottom-pane prompts, chat rendering, history/status
views, and tests move together to keep the stacked branch buildable.
This PR also removes the obsolete compatibility surface that is no
longer used after the migration. The proposed protocol-boundary verifier
layer was dropped from the stack; enforcing that final boundary will be
simpler once `codex-tui` no longer needs any `codex_protocol`
references.
This PR is part 2 of a 2-PR stack:
1. Add TUI-owned replacement models and extract app-server event
routing.
2. Move the active TUI flow to app-server notifications and delete
obsolete adapter code.
## What changed
- Rewired app command and session handling to use app-server request and
notification shapes.
- Moved approval overlays, request-user-input flows, MCP elicitation,
realtime events, and review commands onto the app-server-facing model
surface.
- Updated chat rendering, history cells, status views, multi-agent UI,
replay state, and TUI tests to use app-server notifications plus the
local models introduced in PR1.
- Deleted `codex-rs/tui/src/app/app_server_adapter.rs` and the
superseded `chatwidget/tests/background_events.rs` fixture path.
## Verification
- `cargo check -p codex-tui --tests`
- Top of stack: `cargo test -p codex-tui`
## Why
This stack moves `codex-tui` away from the core protocol event surface
and toward app-server API shapes plus TUI-owned local models. This first
PR sets up the lower-risk foundation: it introduces the local model
surface and extracts app-server event routing into focused TUI modules
while preserving the existing behavior for the larger migration in PR2.
This PR is part 1 of a 2-PR stack:
1. Add TUI-owned replacement models and extract app-server event
routing.
2. Move the active TUI flow to app-server notifications and delete
obsolete adapter code.
## What changed
- Added TUI-owned approval, diff, session state, session resume, token
usage, and user-message models.
- Added `app/app_server_event_targets.rs` and `app/app_server_events.rs`
to hold app-server event targeting and dispatch logic outside `app.rs`.
- Updated app/status tests to use the local model layer and added
focused routing coverage.
- Boxed a few large async TUI test futures so this base layer remains
checkable without overflowing the default test stack.
## Verification
- `cargo check -p codex-tui --tests`
