  • feat(app-server): filter threads by parent (#26662)
    ## Why
    
    Clients that display or coordinate spawned subagents need an
    authoritative snapshot of a thread's immediate spawned children when
    they connect to app-server or recover after missing live events.
    `thread/list` cannot query by parent, so clients must otherwise scan
    unrelated threads or reconstruct relationships from rollout history and
    transient events.
    
    The direct spawn relationship already exists in persisted
    `thread_spawn_edges` state. Review and Guardian threads do not
    participate in that lifecycle and are intentionally outside this
    filter's scope.
    
    ## What changed
    
    This adds an experimental `parentThreadId` filter to `thread/list`.
    Parent-filtered requests return direct spawned children from persisted
    state while preserving the existing response shape, explicit filters,
    sorting, and timestamp-only cursor behavior. The lookup does not read
    rollout transcripts or recursively return descendants.
    
    Supersedes #25112 with the narrower `thread/list` filter approach.
    
    ## How it works
    
    1. An experimental client passes a valid thread ID as `parentThreadId`.
    2. App-server routes the list through the existing thread-store and
    state-database boundaries.
    3. SQLite selects threads whose IDs have a direct persisted spawn edge
    from that parent.
    4. Omitted provider and source filters include all values; explicit
    filters keep ordinary `thread/list` semantics.
    5. Grandchildren, Review threads, and Guardian threads are excluded.
    
    ## Verification
    
    State (144 tests), rollout (69 tests), and focused app-server
    thread-list (31 tests) suites passed. Scoped Clippy checks and
    repository formatting also passed. Coverage includes direct spawned
    children, omitted grandchildren, pagination, malformed IDs, mixed source
    kinds, explicit filters, and operation without rollout files.
  • feat: use encrypted local secrets for CLI auth (#27539)
    ## Why
    
    Windows Credential Manager limits generic credential blobs to 2,560
    bytes. Large serialized ChatGPT auth payloads can exceed that limit, so
    keyring-mode CLI auth needs a backend that keeps only the encryption key
    in the OS keyring and stores the payload in Codex's encrypted
    local-secrets file.
    
    This is the third PR in the encrypted-auth stack:
    
    1. #27504 — feature and config selection
    2. #27535 — auth-specific local-secrets namespaces
    3. This PR — CLI auth implementation and activation
    4. MCP OAuth implementation and activation
    
    ## What Changed
    
    - Added encrypted CLI-auth storage using the `CliAuth` secrets
    namespace.
    - Preserved direct keyring storage for platforms/configurations where it
    remains selected.
    - Selected the backend consistently for login, logout, refresh,
    device-code login, auth loading, and login restrictions.
    - Threaded resolved bootstrap/full config through CLI, exec, TUI,
    app-server account handling, cloud config, and cloud tasks.
    - Removed stale `auth.json` fallback data after successful encrypted
    saves and removed encrypted, direct-keyring, and fallback data during
    logout.
    - Added storage and integration coverage for both direct and encrypted
    keyring modes.
    
    MCP OAuth persistence is intentionally left to the next PR.

  • Remove TUI realtime voice support (#27801)
    ## Why
    
    Removes the realtime audio support from TUI.
    
    ## What Changed
    
    - Removed the TUI `/realtime` and realtime `/settings` command paths.
    - Deleted TUI voice capture/playback, WebRTC session handling,
    audio-device selection UI, and recording-meter code.
    - Removed TUI realtime tests and snapshots that covered the deleted
    surfaces.
    - Dropped the TUI-only `cpal` and `codex-realtime-webrtc` dependencies
    and refreshed the Rust/Bazel locks.
  • Persist update dismissal without cache (#27783)
    ## Summary
    
    Choosing “Don’t remind me” can silently fail when `version.json`
    disappears before dismissal because `dismiss_version` returns success
    without writing anything. The same update can then reappear on the next
    launch.
    
    Initialize a minimal `VersionInfo` from the selected version when the
    cache cannot be read, then persist the dismissal through the existing
    write path.
    
    Fixes #27147
  • [1 of 3] Support long raw TUI goal objectives (#27508)
    ## Stack
    
    1. **[1 of 3] Support long raw TUI goal objectives** - this PR
    2. [2 of 3] Support long pasted text in TUI goals - #27509
    3. [3 of 3] Support images in TUI goals - #27510
    
    ## Why
    
    `thread/goal/set` limits persisted objective text to 4000 characters.
    The TUI used to reject raw `/goal` objectives above that limit, even
    though the client can make them usable by writing the long text to a
    file and storing a short objective that points at that file.
    
    This also needs to work for remote app-server sessions: filesystem API
    calls must create files on the app-server host, and the stored path must
    be meaningful to the agent on that host.
    
    ## What Changed
    
    - Adds an app-server-host path helper so TUI code can build paths that
    are resolved on the app-server host rather than the TUI host.
    - Adds TUI app-server session helpers for `fs/createDirectory`,
    `fs/writeFile`, `fs/readFile`, and `fs/remove` that work for embedded
    and remote app-server sessions without changing the app-server protocol.
    - Materializes oversized raw `/goal` objectives into
    `$CODEX_HOME/attachments/<uuid>/goal-objective.md` through the
    app-server filesystem APIs, then stores a short, readable objective that
    directs the agent to that file.
    - Reads managed objective files back for `/goal edit`. Other goal UI
    renders the readable stored objective normally, without
    managed-file-specific presentation logic.
    - Recognizes managed references only when they name the expected
    generated file under the app server's reported `$CODEX_HOME`, and cleans
    up newly materialized files when goal replacement or setting does not
    complete.
    
    ## Verification
    
    - Added/updated TUI tests for raw oversized `/goal` submission, large
    inline-paste expansion, queued oversized goals, app-facing
    materialization before `thread/goal/set`, managed-path validation,
    editing, and cleanup.
    - Added/updated app-server-client remote coverage for initialized remote
    Codex home handling.
    
    ## Manual Testing
    
    - Ran the real TUI against a Unix-socket app server with different local
    and server `$CODEX_HOME` directories. Oversized goals wrote only under
    the server home, and persisted references used the server-canonical path
    rather than the TUI path.
    - Exercised 3,999-, 4,000-, and 4,001-character raw objectives. The
    first two stayed inline without new files; the 4,001-character objective
    became a managed objective file.
    - Submitted a larger 8,275-character objective, verified its full
    contents on the app-server host, and observed the goal continuation open
    the referenced server-side file.
    - Opened `/goal edit` for a managed objective and verified the full text
    was restored through remote `fs/readFile`.
    - Submitted an oversized replacement while a goal was active, verified
    no file was written before confirmation, then canceled and confirmed
    that the existing goal and attachment count were unchanged.
  • Print TUI session info on fatal exits (#27417)
    ## Summary
    
    TUI exits printed the resume/session summary only after checking the
    exit reason. On fatal exits, both CLI wrappers wrote the error and
    called `process::exit(1)` immediately, so an active session that ended
    on a fatal error could skip the session information entirely.
    
    This change prints the normal exit summary before returning the fatal
    nonzero exit code. If a fatal exit has a known thread id but no
    resumable rollout hint, it prints `Session ID: <id>` instead of staying
    silent. It also flushes stdout before `process::exit(1)` so the summary
    line is not lost during process teardown.
    
    ## Implementation
    
    - Apply the fatal-exit ordering fix in both `codex` and standalone
    `codex-tui`.
    - Keep normal user-requested exit behavior unchanged.
    - Preserve the existing resume hint when a rollout is resumable, and use
    the raw thread id only as a fatal-exit fallback.
  • Remove TUI legacy Windows sandbox dependency (#27490)
    ## Why
    
    This is part of an ongoing attempt to eliminate the TUI's direct
    dependency on core features. When we moved the TUI to the app server, we
    left a `legacy_core` shim that re-exported some remaining core symbols
    for the TUI. The intent was to eventually remove all of these.
    
    In this PR, we remove the symbols related to the Windows sandbox.
    
    The change should be behavior-neutral and low risk because it's just
    refactoring and removal of code that is now effectively dead.
    
    When working on this PR, I noticed a big existing problem that affects
    mixed-platform remoting. For example, if you run the TUI on a Linux box
    and remote into a Windows box, the TUI logic doesn't properly handle
    Windows sandbox setup properly. Fixing this is beyond the scope of this
    PR, but I've left a TODO comment in place so we don't forget.
    
    ## What changed
    
    - Move the remaining TUI-specific sandbox level, setup, telemetry, and
    read-root helpers into `codex-tui`, calling `codex-windows-sandbox`
    directly.
    - Remove the Windows sandbox namespace and read-root grant re-exports
    from the client-side `legacy_core` facade.
    - Remove the dormant pre-elevation prompt fallback guarded by the
    permanently enabled `ELEVATED_SANDBOX_NUX_ENABLED` switch. The reachable
    elevated and non-elevated setup flows remain unchanged.
  • Trim TUI legacy telemetry and migration dependencies (#27487)
    ## Why
    
    The TUI still reached through `codex-app-server-client::legacy_core` for
    process telemetry setup and personality migration, exposing core-only
    details after the TUI moved onto the app-server layer.
    
    This is part of our ongoing efforts to whittle away at the legacy_core
    shim that was left over after migrating the TUI to the app server.
    
    This change is just a refactor/rename and should be behavior-neutral and
    low risk.
    
    ## What changed
    
    - expose OTEL provider construction through the app-server client and
    keep the small process/SQLite telemetry adapters local to the TUI
    - collapse personality migration results to the config-reload decision
    the TUI needs
    - remove the `legacy_core::otel_init` and
    `legacy_core::personality_migration` subnamespaces
  • Add session delete commands in CLI and TUI (#27476)
    ## Summary
    
    The app server exposes `thread/delete`, but users cannot invoke it from
    the CLI or TUI. Because deletion is irreversible, the user-facing
    commands need deliberate confirmation and safer handling of name-based
    targets.
    
    - Add `codex delete <SESSION>` with interactive confirmation,
    restricting `--force` to UUID targets.
    - Resolve exact names across active and archived sessions, including
    renamed sessions, and validate prompted UUID targets before
    confirmation.
    - Add a `/delete` command with a confirmation popup that warns the
    current session and its subagent threads will be permanently deleted.
    
    ## Manual testing
    
    - Deleted by UUID with `--force` and verified the rollout, session-index
    entry, and database row were removed.
    - Exercised name-based confirmation for both cancellation and
    affirmative deletion; cancellation preserved the session and
    confirmation removed it.
    - Verified deletion refuses to proceed without `--force`, while
    `--force` rejects names, including duplicate names.
    - Verified duplicate-name confirmation displays the concrete UUID
    selected.
    - Deleted an archived session by name.
    - Verified an already-missing UUID fails before displaying a
    confirmation prompt.
    - Exercised `/delete` in the TUI: the popup defaults to No, cancellation
    preserves the session, and confirmation deletes the session and exits.
    - Verified that `codex delete` works for both archived and non-archived
    sessions.
  • [codex] add /import for external agents (#27071)
    ## 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

  • [codex] add external agent import picker UX (#27070)
    ## Why
    
    Users need to understand what external-agent data Codex detected, what
    is selected, and how to proceed before an import begins. The updated
    picker makes focus, selection state, and the submission path explicit
    while preserving the existing import backend.
    
    ## What changed
    
    - replace the old migration prompt with a two-step external-agent import
    picker
    - add a customize view with explicit item focus, selection state,
    counts, and a review action
    - separate detected import data into a view model
    - add Unix and Windows snapshots for prompt, item-focus, and
    action-focus states
    
    ## Validation
    
    - `just test -p codex-tui external_agent_config_migration` (10 passed)
    - manually exercised an isolated TUI fixture covering customization,
    selection toggles, review, import, repeated invocation, and session
    resume
    - the broader `just test -p codex-tui` run passed 2,805 tests, with 2
    unrelated guardian feature-flag failures and 4 skipped tests
    
    ## Review note
    
    This is the largest layer in the stack because the interaction state,
    rendering changes, and required snapshots move together. It remains a
    draft in case reviewers prefer a further presentation/state split.

  • [codex] remove blocking external agent migration flow (#27064)
    ## Why
    
    External-agent import should be initiated deliberately instead of
    interrupting eligible TUI startups. This cleanup removes the blocking
    startup flow before the replacement import experience is introduced
    later in the stack.
    
    ## What changed
    
    - remove the startup-blocking external-agent migration prompt
    - remove the now-unused external migration feature gate
    - remove the obsolete TUI app-server migration wrappers
    - retain the dormant picker behind a module-scoped dead-code allowance
    until the next stack item wires it back in
    - keep normal TUI startup focused on entering Codex immediately

  • fix: Auto-recover from corrupted sqlite databases (#26859)
    Further investigation of the sqlite incidents showed that the problems
    are due to corruption from the older version of SQLite that we recently
    upgraded, and that the data is truly corrupted in the root database --
    recovery of all data is not possible. Given that the data is
    reconstructable from the rollouts on disk, we should just auto-backup
    the database and let codex rebuild the rollout info from the disk
    rollouts.
    
    The new behavior is that appserver auto-backs-up and rebuilds (with logs
    reflecting that behavior). The CLI now pops a message letting you know
    this happened and the paths of the backed-up corrupt db and the new
    database. There is also context added so that the desktop app can read
    the rebuild info from it and inform the user with it.
  • multi-agent: add path-based v2 activity tracking (#27007)
    ## Why
    
    Multi-agent v2 identifies agents by canonical paths, but its tool
    handlers still emitted the larger legacy collaboration begin/end events
    built around nickname and role metadata. App-server, rollout-trace,
    analytics, and TUI consumers therefore lacked one compact path-based
    completion signal that behaved consistently across live events and
    replay.
    
    The TUI also needs a bounded `/agent` status surface for v2 agents. It
    should use recent local activity for previews, refresh liveness without
    loading full histories, and keep the legacy picker available when no
    path-backed v2 agent is known.
    
    ## What changed
    
    - Replace the v2 `spawn_agent`, `send_message`, `followup_task`, and
    `interrupt_agent` legacy lifecycle emissions with a success-only
    `SubAgentActivity` event. The event records the tool call ID, occurrence
    time, affected thread, canonical agent path, and `started`,
    `interacted`, or `interrupted` kind.
    - Expose the activity as a completion-only app-server v2
    `subAgentActivity` thread item in live notifications and reconstructed
    history, regenerate the protocol schemas, and count it in sub-agent tool
    analytics.
    - Track canonical paths from live activity and loaded-thread metadata in
    the TUI, and render the activity in live and replayed transcripts.
    - Make `/agent` list running path-backed agents with summaries from
    bounded local event buffers. Each summary is capped at 240 graphemes,
    the scan is capped at six recent items, only the last three wrapped
    lines are shown, and command output is omitted. Liveness falls back to
    metadata-only `thread/read` when local turn state is unavailable.
    - Persist the activity as a terminal rollout-trace runtime payload and
    reduce it to the corresponding spawn, send, follow-up, or close
    interaction edge. `interrupt_agent` is classified as a close-edge
    operation.
    - Preserve the legacy picker when no path-backed v2 agent is known.
    
    ## Compatibility
    
    App-server v2 clients that consumed `collabAgentToolCall` begin/end
    pairs for these tools must handle the new completion-only
    `subAgentActivity` item. Legacy v1 collaboration behavior is unchanged.
    
    ## Screenshot

    ## Testing
    
    - `just test -p codex-app-server-protocol`
    - `just test -p codex-rollout-trace`
    - Added focused coverage for activity analytics, terminal trace
    serialization, spawn-edge reduction, `interrupt_agent` classification,
    TUI status rendering without aggregated command output, and clearing
    stale running state after a completed turn.
  • Preserve cloud requirements across TUI thread resets (#25177)
    Fixes a TUI regression where thread transitions such as `/new` and
    `/clear` could rebuild config without the cloud requirements loader,
    allowing users to fall back to non-cloud-managed settings. The config
    refresh path now preserves cloud requirements during thread
    reinitialization, and config loading is moved off the deep TUI event
    stack to avoid stack-overflow crashes during those reloads.
    
    - Passes the cloud requirements loader through TUI config rebuild paths.
    - Keeps cloud requirements applied for `/new`, `/clear`, `/fork`, side
    conversations, and session picker transitions.
    - Runs config building on a Tokio task so reloads do not occur on the
    deep TUI caller stack.
    - Adds regression coverage that cloud requirements survive
    thread-transition config refreshes.
    
    ## Test/Repro:
      - Start Codex with a cloud requirement applied.
      - Use `/new` or `/clear`.
    - The refreshed/fresh-session config should still include the cloud
    requirements
      
    This can be tested with any config item, at this moment for oai staff
    the easiest item to test is the `mentions_v2` feature. This is currently
    enabled in cloud requirements, but is not enabled by default. As a
    result, prior to these changes that feature is disabled after `/new` or
    `/clear`. Testing the same steps with a binary from this branch should
    not drop the feature enablement.
  • fix(tui): linkify complete bare URLs with tildes (#27088)
    ## Background
    
    Bare URLs containing `~` in their path are currently only clickable up
    to the tilde in the interactive TUI. For example, Codex renders the
    visible text for:
    
    
    `https://www.cs.tufts.edu/~nr/cs257/archive/olin-shivers/dissertation.pdf`
    
    but the OSC 8 destination stops at `https://www.cs.tufts.edu/`. This
    makes Cmd-click open the wrong location even though the terminal
    recognizes the complete URL outside Codex.
    
    Fixes #26774.
    
    ## Root Cause
    
    The URL scanner already accepts `~`. The truncation happens earlier:
    with strikethrough parsing enabled, `pulldown-cmark` splits this URL
    into adjacent decoded `Event::Text` values around the tilde. The
    Markdown renderer annotated each text event independently, so only the
    first event still looked like a complete URL with a supported scheme.
    
    The renderer now merges adjacent decoded text events before URL
    annotation. It preserves the combined source range while retaining
    parser-decoded contents, which avoids regressing entities such as
    `&amp;`.
    
    ## Changes
    
    - Add a small iterator that merges adjacent decoded Markdown text events
    and their source ranges.
    - Apply it at the Markdown renderer boundary before hyperlink detection.
    - Add regression coverage for the reported URL in prose, wrapped table
    output, and entity-decoded URLs.
    
    ## How to Test
    
    1. Run Codex with `just c`.
    2. Ask the assistant to output this exact bare URL with no Markdown link
    syntax:
    
    `https://www.cs.tufts.edu/~nr/cs257/archive/olin-shivers/dissertation.pdf`
    3. Hold Cmd and hover or click the URL.
    4. Confirm the complete URL, including the suffix after `~`, is one
    destination.
    5. Repeat with the URL inside a Markdown table and confirm wrapped

  • [codex] Gate terminal visualization instructions in TUI (#26013)
    ## Summary
    - add `Feature::TerminalVisualizationInstructions` as
    `UnderDevelopment`, disabled by default
    - keep terminal visualization instructions inside the TUI package
    - append them to existing developer instructions for TUI start, resume,
    and fork flows only when enabled
    - intentionally do not apply them to `codex exec`
    
    ## Rollout
    Control behavior is unchanged. TUI dogfooders can enable
    `terminal_visualization_instructions`; no default user receives the new
    terminal-specific instructions.
    
    The shared visualization-selection rule is supplied separately through
    the `codex_proxy_model_3` Statsig layer for every target Codex model
    slug in the gated cohort. This TUI feature determines how to render an
    appropriate visualization on the terminal surface; the model-layer
    treatment determines when to use one.
    
    ## Validation
    - `cargo test -p codex-tui
    terminal_visualization_instructions_are_gated_for_all_tui_thread_flows
    --lib`
    - `cargo test -p codex-features --lib`
    - `cargo fmt --all -- --check`
    - `git diff --check`
    - GPT-5.4 and GPT-5.5 real prompt-pipeline smoke tests: both visualized
    the positive mapping case, abstained on the negative route case, and
    passed exact prompt-stack verification on CLI and App
    - refreshed onto current `main` with a clean merge and reran the focused
    validation
    
    The full 53-probe all-model treatment comparison and requested
    production coding evals remain rollout gates before broadening beyond
    the initial employee cohort.
    
    This PR remains open for normal human review.
  • Speed up TUI startup by reusing plugin discovery (#26469)
    ## Summary
    
    TUI startup loads related plugin data from `hooks/list`, session MCP
    initialization, and plugin skill warmup. These paths repeated filesystem
    discovery and emitted the same plugin warnings, while `hooks/list` and
    account/model bootstrap ran serially.
    
    This change:
    
    - Reuses one immutable plugin load outcome across startup consumers.
    - Keys the cache only on plugin-relevant configuration.
    - Single-flights concurrent plugin loads and prevents invalidated loads
    from repopulating the cache.
    - Runs hook discovery and account/model bootstrap concurrently.
    - Preserves configuration-migration ordering, hook review behavior, and
    accurate startup telemetry.
    
    In 10 alternating release-build launches in the Ruff repository with the
    existing `~/.codex` configuration, median time to the first editable
    composer decreased from 833ms to 504ms. The branch was faster in 9 of 10
    pairs, with a paired median improvement of 312ms.
  • Use state DB first for resume --last (#26462)
    ## Summary
    
    `codex resume --last` currently lists sessions by updated time using
    scan-and-repair. Updated-time filesystem listing must stat every rollout
    before applying the cwd, provider, and source filters, so startup scales
    with the entire local session history...
    
    This change queries the state DB first for the latest matching session.
    For local workspaces, we only accept the indexed result when its rollout
    path still exists; otherwise we retry with scan-and-repair. The same
    lookup path is shared by `fork --last`.
    
    I benchmarked the same `thread/list` request used by `resume --last` in
    my local `ruff` checkout against a Codex home with 2,599 active rollouts
    totaling 3.7 GiB, including 90 Ruff threads.
    
    Across five fresh release app-server processes with warm filesystem
    caches, the state-DB-only lookup had median latency of 0.37-0.44 ms,
    while scan-and-repair had median latency of 139-162 ms. First-request
    latency was 0.7-1.7 ms versus 142-185 ms.
    
    So this **removes roughly 140-160 ms from the `resume --last` lookup**
    on this machine, and makes that lookup over 300x faster.
    
    The tradeoff is that this does leave two correctness gaps:
    
    - If a newer matching rollout is missing from SQLite but an older
    matching row exists, the fast path resumes the older thread and never
    falls back to the filesystem scan.
    - If an existing row has stale filter or ordering metadata, the fast
    path can select a different thread from scan-and-repair. The rollout
    tests already demonstrate this for stale cwd metadata: state-DB-only
    returns the stale match, while scan-and-repair removes and repairs it.
    
    So you could end up seeing the "wrong" result in cases like...
    
    1. A crash or SQLite error occurs between Codex writing the conversation
    file and updating SQLite, leaving the newer file unindexed.
    
    2. An older Codex version, restore, or manual copy adds a conversation
    file after SQLite’s one-time backfill completed.
    
    These seem pretty rare though (and sessions can always be recovered via
    other mechanisms -- `--last` is just a convenience feature), and I think
    the tradeoffs are good here?
  • Switch runtime to cloud config bundle (#24622)
    ## Summary
    
    - Adapts the moved `codex-cloud-config` crate from the legacy cloud
    requirements endpoint to the new config bundle endpoint.
    - Switches runtime consumers from `CloudRequirementsLoader` to
    `CloudConfigBundleLoader` so one shared bundle supplies cloud-delivered
    config and requirements.
    - Removes the legacy cloud requirements domain loader path.
    
    ## Details
    
    This intentionally keeps `codex-cloud-config` monolithic for review
    lineage: the previous PR establishes the crate move, and this PR shows
    the behavior change against that moved implementation. A follow-up PR
    splits the module back into focused files.
    
    The new bundle path preserves the important cloud requirements loader
    semantics where intended: account-scoped signed cache, 30 minute TTL, 5
    minute refresh cadence, retry/backoff, auth recovery, and fail-closed
    startup loading. The cached payload changes from a single requirements
    TOML string to the backend-delivered bundle, and validation rejects
    malformed config or requirements fragments before cache write/use.
  • Move cloud requirements crate to cloud config (#24621)
    ## Summary
    
    - Moves the existing `codex-cloud-requirements` crate to
    `codex-cloud-config`.
    - Updates workspace dependencies and imports to the new crate name.
    - Intentionally keeps runtime behavior unchanged: this still fetches the
    legacy cloud requirements endpoint.
    
    ## Details
    
    This PR exists to make the lineage obvious before the bundle migration.
    GitHub should show the old `codex-rs/cloud-requirements/src/lib.rs`
    implementation as moved to `codex-rs/cloud-config/src/lib.rs`, rather
    than as unrelated new code.
    
    The follow-up PR adapts this moved crate to the new config bundle API
    and switches runtime consumers over.
  • Add thread archive CLI commands (#25021)
    ## Problem
    
    Saved threads can already be archived through app-server RPCs, but the
    command line did not expose direct archive or unarchive commands.
    
    ## Solution
    
    Add `codex archive <thread>` and `codex unarchive <thread>`, resolving
    UUIDs or exact thread names before calling the existing `thread/archive`
    and `thread/unarchive` RPCs. The commands support scoped remote flags so
    callers can target remote app-server endpoints when archiving or
    unarchiving threads.
    
    This also fixes a long-standing bug in `codex resume <thread id>` and
    `codex fork <thread id>` that I found when testing the new commands.
    These operations shouldn't be allowed on archived sessions. They now
    fail with an error that tells the user to run `codex unarchive <thread
    id>` first.
    
    ## Verification
    
    Added app-server coverage for rejecting archived thread resume by id and
    checking that the error includes the matching `codex unarchive <thread
    id>` command.
  • Constrain Windows sandbox requirements (#23766)
    # Why
    
    Managed requirements can already constrain sandbox policy choices, but
    Windows sandbox implementation selection was still resolved
    independently from those requirements. That left the TUI able to
    continue through the unelevated fallback even when an organization wants
    to require the elevated Windows sandbox implementation.
    
    # What
    
    - Add `[windows].allowed_sandbox_implementations` requirements support
    for the Windows `elevated` and `unelevated` implementations.
    - Apply that allowlist during core config resolution so disallowed
    configured or feature-selected Windows sandbox implementations fall back
    to an allowed implementation with the existing requirements warning
    path.
    - Reuse the existing TUI Windows setup prompts to block disallowed
    unelevated continuation, keep required elevated setup in front of the
    user, and refuse to persist a TUI-selected Windows sandbox mode that
    requirements disallow.
    
    # Semantics
    
    | Allowed | Selected | Effective |
    | --- | --- | --- |
    | `["elevated"]` | `unelevated` / unset | `elevated` |
    | `["unelevated"]` | `elevated` / unset | `unelevated` |
    | `["elevated", "unelevated"]` | `elevated` | `elevated` |
    | `["elevated", "unelevated"]` | `unelevated` | `unelevated` |
    | `["elevated", "unelevated"]` | unset | `elevated` |
    
    Availability is handled by interactive setup surfaces after allowlist
    resolution. If the effective elevated implementation is not ready,
    elevated-only requirements block on setup. When unelevated is also
    allowed, the UI may offer the existing unelevated fallback.
    
    ## TUI Screens
    
    If elevated setup is not already complete:
    ```
      Your organization requires the default Codex agent sandbox to continue. Set it up to protect your files and control
      network access.
      Learn more <https://developers.openai.com/codex/windows>
    
    › 1. Set up default sandbox (requires Administrator permissions)
      2. Quit
    ```
    
    If admin setup fails under `["elevated"]`:
    ```
      Couldn't set up your sandbox with Administrator permissions
    
      Your organization requires the default sandbox before Codex can continue.
      Learn more <https://developers.openai.com/codex/windows>
    
    › 1. Try setting up admin sandbox again
      2. Quit
    ```
    
    # Next Steps
    
    
    - extend the requirements/readout surface, such as
    `configRequirements/read`, so clients can inspect the loaded
    `[windows].allowed_sandbox_implementations` requirement instead of
    inferring it from Windows setup state
    - consider extending `windowsSandbox/readiness` as well
    - update the App startup guide, setup flow, and banner surfaces so an
    elevated-only requirement omits any continue-unelevated escape hatch and
    blocks startup until a permitted implementation is ready;
    - preserve the existing unelevated fallback path when requirements allow
    it, including the `["unelevated"]` case where elevated is disallowed
  • feat(tui): add OSC 8 web links to rich content (#24472)
    ## Why
    
    Wrapped URLs in rich TUI output, especially URLs rendered inside
    Markdown tables, are split across terminal rows. In terminals that
    support OSC 8 hyperlinks, treating each visible fragment as part of the
    complete destination enables reliable open-link and copy-link actions
    even after table layout wraps the URL.
    
    This addresses the semantic-link portion of #12200 and the behavior
    described in
    https://github.com/openai/codex/issues/12200#issuecomment-4535452980. It
    does not change ordinary drag-selection across bordered table rows.
    
    ## What Changed
    
    - Added shared TUI OSC 8 support that validates `http://` and `https://`
    destinations, sanitizes terminal payloads, and applies metadata
    separately from visible line width/layout.
    - Added semantic web-link annotations to assistant and proposed-plan
    Markdown, including explicit web links and bare web URLs in prose and
    table cells while excluding code and non-web Markdown destinations.
    - Preserved complete URL targets through table wrapping, narrow pipe
    fallback, streaming, transcript overlay rendering, history insertion,
    and resize replay.
    - Routed intentional Codex-owned links in notices,
    status/setup/app-link, feedback, onboarding, MCP/plugin help, memories,
    and update surfaces through the shared hyperlink handling.
    
    ## How to Test
    
    1. Run Codex in a terminal with OSC 8 link support, such as Ghostty, and
    request an assistant response containing a Markdown table whose last
    column contains a long `https://` URL.
    2. Make the terminal narrow enough for the URL to wrap across multiple
    bordered table rows.
    3. Use the terminal's open-link or copy-link action on more than one
    wrapped URL fragment and confirm each fragment resolves to the complete
    original URL.
    4. Resize the terminal after the table is rendered and repeat the link
    action to confirm the destination survives scrollback replay.
    5. Open the transcript overlay while rich output is present and confirm
    web links remain interactive there.
    6. As a regression check, render inline/fenced code containing URL text
    and a Markdown link such as
    `[https://example.com](mailto:support@example.com)`; confirm these do
    not acquire a web OSC 8 destination.
    
    Targeted automated coverage exercised Markdown links and exclusions,
    wrapped and pipe-fallback tables, streaming/transcript overlay
    propagation, status-link truncation, and rendered word-wrapping cell
    alignment. `just test -p codex-tui` was also run; it passed the
    hyperlink coverage and reproduced two unrelated existing guardian
    feature-flag test failures.
  • tui: include exec sessions in resume list (#24503)
    ## Why
    
    Fixes #24502.
    
    `codex resume --include-non-interactive` should include sessions created
    by `codex exec`, but the TUI was sending no `sourceKinds` filter to
    `thread/list` for that mode. `thread/list` treats omitted or empty
    `sourceKinds` as interactive-only (`cli`, `vscode`), so exec sessions
    were still filtered out.
    
    ## What Changed
    
    - Added a shared TUI `resume_source_kinds` helper so both resume lookup
    paths always pass explicit `sourceKinds` to `thread/list`.
    - Kept the default resume behavior scoped to `cli` and `vscode`.
    - Made `--include-non-interactive` include `exec` and `appServer`
    sessions, while continuing to exclude subagent and unknown sources.
    
    ## Verification
    
    Added focused coverage for both affected TUI request builders:
    
    - `latest_session_lookup_params_can_include_non_interactive_sources`
    - `remote_thread_list_params_can_include_non_interactive_sources`
  • fix(tui): prevent macos stderr from corrupting composer (#24459)
    ## Why
    
    Fixes #17139.
    
    On macOS, runtime diagnostics such as `MallocStackLogging` messages can
    be written directly to process stderr while the inline TUI owns the
    terminal. Those bytes paint into the same viewport as the composer
    without passing through the renderer or composer state, making
    diagnostic output appear to leak into the input area.
    
    ## What Changed
    
    - Add a macOS terminal stderr guard while the inline TUI owns the
    viewport.
    - Restore stderr when Codex returns terminal ownership for external
    interactive programs, suspend/resume, panic handling, and normal
    shutdown.
    - Add an fd-level regression test that verifies output is suppressed
    only while terminal ownership is held and restored at each handoff
    boundary.
    
    ## How to Test
    
    1. On macOS, launch the interactive TUI and leave the composer visible.
    2. Exercise the workflow that triggers an allocator/runtime stderr
    diagnostic during an active session, as reported in #17139.
    3. Confirm the diagnostic no longer overwrites the active composer
    region.
    4. Suspend or exit the TUI and confirm subsequent terminal stderr output
    remains visible.
    
    The platform diagnostic is environment-dependent, so the deterministic
    regression check is the new fd-lifecycle test in
    `tui::terminal_stderr::tests::suppresses_stderr_only_while_terminal_is_owned`.
    
    Targeted validation:
    - `just argument-comment-lint-from-source -p codex-tui` passed.
    - `just test -p codex-tui` exercised and passed the new stderr-guard
    regression test. The full invocation currently fails in two unrelated
    guardian-policy tests,
    `update_feature_flags_disabling_guardian_clears_review_policy_and_restores_default`
    and
    `update_feature_flags_disabling_guardian_clears_manual_review_policy_without_history`,
    which reproduce when rerun in isolation.
  • TUI config cleanup: trusted projects (#24255)
    ## Why
    TUI onboarding trusted-project persistence should go through the same
    app-server config write path as other config mutations. Writing
    `config.toml` directly from the trust widget bypasses that layer and can
    let onboarding proceed even when the trust decision was not actually
    persisted.
    
    ## What changed
    - Added a TUI config helper that writes the existing project trust
    structure through `config/batchWrite`.
    - Persists trust decisions as `projects.<project>.trust_level =
    "trusted"` using the existing project trust key helper.
    - Changed the trust directory widget to only record the user selection;
    onboarding performs the app-server write before reporting success.
    - Keeps the user on the trust screen and shows an error if app-server
    persistence fails.
    
    ## Verification
    - `cargo test -p codex-tui --lib
    trust_persistence_failure_keeps_trust_step_in_progress`
    - `cargo test -p codex-tui --lib
    trusted_project_edit_targets_project_trust_level`
    - Manual: built the local `codex-cli`, accepted the trust prompt in a
    temp project, confirmed `projects.<project>.trust_level = "trusted"`,
    and simulated an unwritable config to verify onboarding stays on the
    trust screen without writing trust.
  • TUI config cleanup: oss_provider (#24254)
    ## Summary
    
    Manual provider selection during `codex --oss` startup was still
    persisting `oss_provider` through the legacy local `config.toml` writer.
    That bypasses the app-server-owned config mutation path used by the TUI,
    so this routes the write through the app server config API instead.
    
    The net behavior is intentionally narrow: only an interactive picker
    selection is persisted. Auto-detected single-running-provider startup
    and explicit `--local-provider` startup remain ephemeral, so merely
    having one backend running does not make that provider sticky for future
    runs.
    
    ## What Changed
    
    - Removed the TUI picker’s direct dependency on
    `set_default_oss_provider`.
    - Had `oss_selection` report whether the returned provider came from the
    interactive picker.
    - Carried only manually selected providers into startup persistence.
    - Wrote `oss_provider` via `config/batchWrite` once the app server
    session is available.
    - Logged a warning and continued startup if the app-server config write
    fails.
    
    ## Verification
    
    Manually smoke-tested the real `codex-tui` binary with a temporary
    `CODEX_HOME`, pseudo-terminal input, and a fake LM Studio HTTP server:
    
    - Interactive picker selection persisted `oss_provider = "lmstudio"`.
    - Non-picker `--local-provider lmstudio` startup did not persist
    `oss_provider`.
  • Respect hook trust bypass during TUI startup (#24317)
    Fixes #24093.
    
    ## Why
    
    `--dangerously-bypass-hook-trust` is a supported CLI flag intended for
    headless or automated runs where enabled hooks should be allowed to run
    without requiring persisted trust. In the TUI, startup hook review still
    opened whenever hooks looked untrusted, so a launch using the bypass
    could block on the interactive "Hooks need review" prompt.
    
    The tricky case is persistent app-server resume: a resume may attach to
    an already-running thread, where resume config overrides are ignored. In
    that path, hiding the startup review would be wrong because the existing
    hook engine may still filter untrusted hooks.
    
    ## What Changed
    
    - Startup hook review now skips the prompt only when hook trust bypass
    is actually safe for that launch.
    - The TUI forwards `bypass_hook_trust` through the app-server request
    config for fresh thread start/resume/fork paths, and the app-server
    applies it as a runtime-only `ConfigOverrides` value rather than
    treating it like a `config.toml` setting.
    - Persistent app-server resumes keep the startup review prompt so users
    still have a chance to trust hooks when the running thread cannot
    receive the bypass override.
    
    ## Verification
    
    - Added focused coverage for startup hook review with and without
    `bypass_hook_trust`.
    - Extended existing TUI/app-server config override tests to cover
    forwarding and applying `bypass_hook_trust`.
  • tui: make codex-tui.log opt-in (#24081)
    ## Why
    
    The TUI currently creates a shared plaintext `codex-tui.log` under the
    default log directory. That append-only file can keep growing across
    runs even though the TUI already records diagnostics in bounded local
    stores.
    
    Make the plaintext file log an explicit troubleshooting choice instead
    of a default side effect.
    
    This is possible because logs are also stored in the DB with proper
    rotation
    
    ## What changed
    
    - Only install the TUI file logging layer when `log_dir` is explicitly
    set.
    - Remove the prior `codex-tui.log` at startup before an opt-in file
    layer is created.
    - Clarify the `log_dir` config/schema text and `docs/install.md` example
    so users opt in with `codex -c log_dir=...` when they need a plaintext
    log.
  • config: remove legacy profile write paths (#24055)
    ## Why
    
    [#23883](https://github.com/openai/codex/pull/23883) moved the
    user-facing `--profile` flag onto profile v2 and
    [#23886](https://github.com/openai/codex/pull/23886) removed CLI
    forwarding for the legacy profile-v1 path. Core and TUI config
    persistence still carried `active_profile` and
    `ConfigEditsBuilder::with_profile`, which let later writes continue
    targeting legacy `[profiles.<name>]` tables after profile selection
    moved to profile-v2 config files.
    
    ## What
    
    - Remove legacy profile routing from
    [`ConfigEditsBuilder`](https://github.com/openai/codex/blob/4b38e9c22e762261d7f7eef49d8a21792e241a06/codex-rs/core/src/config/edit.rs#L1064-L1294),
    so core config edits no longer carry `with_profile` or infer
    `[profiles.*]` write targets from a `profile` key.
    - Drop `active_profile` plumbing from runtime `Config`, TUI
    startup/state, app-server config override forwarding, and Windows
    sandbox setup persistence.
    - Make app-server-backed TUI config edits use unscoped model,
    service-tier, feature, Auto-review, plan-mode, and Windows sandbox paths
    through
    [`tui/src/config_update.rs`](https://github.com/openai/codex/blob/4b38e9c22e762261d7f7eef49d8a21792e241a06/codex-rs/tui/src/config_update.rs#L43-L112).
    - Update config edit coverage so legacy `profile` state stays untouched
    by direct model writes, and remove tests whose only contract was the
    deleted profile-scoped persistence path.
    
    ## Testing
    
    - Not run locally.
  • config: remove legacy profile v1 resolution (#24051)
    ## Why
    
    [#23883](https://github.com/openai/codex/pull/23883) moved user-facing
    `--profile` selection onto profile v2, and
    [#23886](https://github.com/openai/codex/pull/23886) removed the old CLI
    `config_profile` override path. Core still had a second legacy path:
    `profile = "..."` could select `[profiles.*]` values while runtime
    config was built. Keeping that resolver alive preserves the old
    precedence model and profile-carrying surfaces even though profile
    selection now points at `$CODEX_HOME/<name>.config.toml`.
    
    ## What
    
    - Reject legacy top-level `profile = "..."` config while loading runtime
    config, with an error that points callers at `--profile <name>` and
    `<name>.config.toml` in the [core load
    path](https://github.com/openai/codex/blob/3d923366eca10a29143623124c6c6e538f058269/codex-rs/core/src/config/mod.rs#L2524-L2531).
    - Remove the remaining profile-v1 merge points from runtime config
    resolution, including features, permissions, model/provider selection,

  • cli: remove legacy profile v1 plumbing (#23886)
    ## Why
    
    [#23883](https://github.com/openai/codex/pull/23883) moved the
    user-facing `--profile` flag onto profile v2. The shared CLI option
    layer still carried the old `config_profile` slot and several CLI
    entrypoints still copied that value into legacy config overrides.
    Leaving that path around makes the CLI surface look like it still
    selects legacy `[profiles.*]` state even though `--profile` now means
    `$CODEX_HOME/<name>.config.toml`.
    
    ## What
    
    - Remove the legacy `config_profile` field and merge/copy path from
    [`SharedCliOptions`](https://github.com/openai/codex/blob/95baaf72920c8db22097df8d15a0bb76c84528b6/codex-rs/utils/cli/src/shared_options.rs#L8-L177).
    - Stop forwarding profile-v1 overrides from CLI, exec, TUI, doctor,
    debug, feature, and exec-server paths; runtime profile selection remains
    on `config_profile_v2` through
    [`loader_overrides_for_profile`](https://github.com/openai/codex/blob/95baaf72920c8db22097df8d15a0bb76c84528b6/codex-rs/cli/src/main.rs#L1606-L1619).
    - Resolve local OSS provider selection from the base config in exec and
    TUI now that the legacy profile argument is gone.
    
    ## Testing
    
    - Not run (cleanup-only follow-up to #23883).
  • Honor client-resolved service tier defaults (#23537)
    ## Why
    
    Model catalog responses can now advertise a nullable
    `default_service_tier` for each model. Codex needs to preserve three
    distinct states all the way from config/app-server inputs to inference:
    
    - no explicit service tier, so the client may apply the current model
    catalog default when FastMode is enabled
    - explicit `default`, meaning the user intentionally wants standard
    routing
    - explicit catalog tier ids such as `priority`, `flex`, or future tiers
    
    Keeping those states distinct prevents the UI from showing one tier
    while core sends another, especially after model switches or app-server
    `thread/start` / `turn/start` updates.
    
    ## What Changed
    
    - Plumbed `default_service_tier` through model catalog protocol types,
    app-server model responses, generated schemas, model cache fixtures, and
    provider/model-manager conversions.
    - Added the request-only `default` service tier sentinel and normalized
    legacy config spelling so `fast` in `config.toml` still materializes as
    the runtime/request id `priority`.
    - Moved catalog default resolution to the TUI/client side, including
    recomputing the effective service tier when model/FastMode-dependent
    surfaces change.
    - Updated app-server thread lifecycle config construction so
    `serviceTier: null` preserves explicit standard-routing intent by
    mapping to `default` instead of internal `None`.
    - Kept core responsible for validating explicit tiers against the
    current model and stripping `default` before `/v1/responses`, without
    applying catalog defaults itself.
    
    ## Validation

  • Fix: TUI starting in wrong CWD (#23538)
    This fixes a regression wher codex could start in the wrong directory
    when a live local app-server socket was present. The issue was that
    implicit local socket reuse was being treated like an explicit remote
    workspace session, which dropped the invoking cwd unless --cd was
    passed.
    
    The change separates local socket transport from true remote workspace
    semantics.
    - Plain local startup keeps local cwd, trust, resume, picker, and
    config-refresh behavior.
    - Explicit --remote keeps the existing remote cwd behavior.
    - Added coverage for launch target selection and local-session
    filtering/cwd behavior.
    
    Steps to test:
    - Start a local app-server from a different directory than the repo you
    want to use.
      - Launch codex from a project/worktree without --cd.
    - Confirm the session starts in the invoking directory, not the
    app-server process directory.
    - Confirm explicit codex --remote ... still preserves existing remote
    behavior.

  • [1 of 2] Optimize TUI startup terminal probes (#23175)
    ## Why
    
    Codex TUI startup still feels slower than 0.117.0 after the app-server
    move in 0.118.0. A visible chunk of launch-to-input latency comes from
    serial terminal startup probes: cursor position, keyboard enhancement
    support, and default foreground/background color queries can each wait
    on terminal responses before the first usable frame.
    
    Refs #16335.
    
    ## What
    
    This PR batches the terminal startup probes into one bounded probe. It
    also reuses the probed cursor position and default colors during TUI
    setup, fast-paths the primary-device-attributes fallback as keyboard
    enhancement unsupported, and keeps lightweight startup timing logs for
    future tuning.
    
    The startup telemetry is intentionally left in production: it records
    phase timings for terminal probes and initial-frame scheduling so future
    startup regressions can be diagnosed from normal logs rather than
    re-adding one-off debug instrumentation.
    
    ## Benchmark
    
    In the local pty startup benchmark, the pre-optimization `main` baseline
    was about 250.5ms median from launch to accepted chat input. This
    probe-only branch measured about 152ms median, for an approximate
    savings of 95-100ms.

  • [1 of 4] tui: route primary settings writes through app server (#22913)
    ## Why
    The TUI can run against a remote app server, but several high-traffic
    settings still persisted by editing the local config file. That sends
    remote sessions' preference writes to the wrong machine and lets local
    disk state drift from the app-server-owned config.
    
    This is **[1 of 4]** in a stacked series that moves TUI-owned config
    mutations onto app-server APIs.
    
    ## What changed
    - Added a small TUI helper for typed app-server config writes.
    - Routed primary interactive preference writes through
    `config/batchWrite`.
    - Preserved existing profile scoping for settings that already support
    `profiles.<profile>.*` overrides.
    
    ## Config keys affected
    - `model`
    - `model_reasoning_effort`
    - `personality`
    - `service_tier`
    - `plan_mode_reasoning_effort`
    - `approvals_reviewer`
    - `notice.fast_default_opt_out`
    - Profile-scoped equivalents under `profiles.<profile>.*`
    
    ## Suggested manual validation
    - Connect the TUI to a remote app server, change `model` and
    `model_reasoning_effort`, reconnect, and confirm the remote config
    retained both values while the local `config.toml` did not change.
    - Change `personality`, `plan_mode_reasoning_effort`, and the explicit
    auto-review selection, then reconnect and confirm those choices persist
    through the app server.
    - Clear the service tier back to default and confirm `service_tier` is
    cleared while `notice.fast_default_opt_out = true` is persisted
    remotely.
    - Repeat one setting change with an active profile and confirm the write
    lands under `profiles.<profile>.*`.

    startup and onboarding bookkeeping
  • tui: recover local state db startup failures (#22734)
    ## Why
    
    #22580 made app-server startup fail when the local SQLite state database
    cannot be initialized. Embedded/local TUI startup still continued on the
    permissive path, which left the CLI inconsistent and could hide a real
    startup problem behind unrelated UI. This brings local TUI startup onto
    the same fail-closed behavior while keeping recovery humane for the two
    failure modes we are seeing in practice: damaged database files and
    startup stalls caused by another process holding the database write
    lock.
    
    ## What changed
    
    - Embedded TUI startup now uses `state_db::try_init(...)` and returns a
    typed `LocalStateDbStartupError` that preserves the affected database
    path plus the underlying failure detail.
    - CLI startup handles that failure before entering the interactive TUI:
    - lock-contention failures tell users to quit other Codex processes and
    try again
    - failures consistent with a broken local database offer a safe repair
    that backs up Codex-owned SQLite files, rebuilds local database files,
    and retries startup once
    - declined or unsuccessful repairs print concise guidance plus technical
    details
    - Shared startup error plumbing lives in `tui/src/startup_error.rs`,
    while CLI recovery policy and focused recovery tests live in
    `cli/src/state_db_recovery.rs`.
    
    ## Verification
    
    - `cargo test -p codex-tui
    embedded_state_db_failure_is_typed_for_cli_recovery`
    - `cargo test -p codex-cli state_db_recovery`
    - Manually held an exclusive SQLite lock on `state_5.sqlite` and
    confirmed the CLI shows lock-specific guidance without offering repair.
    - Manually exercised the repair path with a deliberately invalid
    `sqlite_home` and confirmed it backs up the blocking path and resumes
    startup.
  • permissions: support workspace roots in profiles (#22610)
    ## Why
    
    This is the configuration/model half of the alternative permissions
    migration we discussed as a comparison point for
    [#22401](https://github.com/openai/codex/pull/22401) and
    [#22402](https://github.com/openai/codex/pull/22402).
    
    The old `workspace-write` model mixes three concerns that we want to
    keep separate:
    - reusable profile rules that should stay immutable once selected
    - user/runtime workspace roots from `cwd`, `--add-dir`, and legacy
    workspace-write config
    - internal Codex writable roots such as memories, which should not be
    shown as user workspace roots
    
    This PR gives permission profiles first-class `workspace_roots` so users
    can opt multiple repositories into the same `:workspace_roots` rules
    without using broad absolute-path write grants. It also starts
    separating the raw selected profile from the effective runtime profile
    by making `Permissions` expose explicit accessors instead of public
    mutable fields.
    
    A representative `config.toml` looks like this:
    
    ```toml
    default_permissions = "dev"
    
    [permissions.dev.workspace_roots]
    "~/code/openai" = true
    "~/code/developers-website" = true
    
    [permissions.dev.filesystem.":workspace_roots"]
    "." = "write"
    ".codex" = "read"
    ".git" = "read"
    ".vscode" = "read"
    ```
    
    If Codex starts in `~/code/codex` with that profile selected, the
    effective workspace-root set becomes:
    - `~/code/codex` from the runtime `cwd`
    - `~/code/openai` from the profile
    - `~/code/developers-website` from the profile
    
    The `:workspace_roots` rules are materialized across each root, so
    `.git`, `.codex`, and `.vscode` stay scoped the same way everywhere.
    Runtime additions such as `--add-dir` can still layer on later stack
    entries without mutating the selected profile.
    
    ## Stack Shape
    
    This PR intentionally stops before the profile-identity cleanup in
    [#22683](https://github.com/openai/codex/pull/22683) so the base review
    stays focused on config loading, workspace-root materialization, and
    compatibility with legacy `workspace-write`.
    
    The representation in this PR is therefore transitional: `Permissions`
    carries enough state to distinguish the raw constrained profile from the
    effective runtime profile, and there are still call sites that must keep
    the active profile identity and constrained profile value in sync. The
    follow-up PR replaces that with a single resolved profile state
    (`ResolvedPermissionProfile` / `PermissionProfileState`) that keeps the
    profile id, immutable `PermissionProfile`, and profile-declared
    workspace roots together. That follow-up removes APIs such as
    `set_constrained_permission_profile_with_active_profile()` where
    separate arguments could drift out of sync.
    
    Downstream PRs then build on this base to switch app-server turn updates
    to profile ids plus runtime workspace roots and to finish the
    user-visible summary behavior. Reviewers should judge this PR as the
    workspace-roots foundation, not as the final in-memory shape of selected
    permission profiles.
    
    ## Review Guide
    
    Suggested review order:
    
    1. Start with `codex-rs/core/src/config/mod.rs`.
    This is the main shape change in the base slice. `Permissions` now
    stores a private raw `Constrained<PermissionProfile>` plus runtime
    `workspace_roots`. Callers use `permission_profile()` when they need the
    raw constrained value and `effective_permission_profile()` when they
    need a materialized runtime profile. As noted above,
    [#22683](https://github.com/openai/codex/pull/22683) replaces this
    transitional shape with a resolved profile state that keeps identity and
    profile data together.
    
    2. Review `codex-rs/config/src/permissions_toml.rs` and
    `codex-rs/core/src/config/permissions.rs`.
    These add `[permissions.<id>.workspace_roots]`, resolve enabled entries
    relative to the policy cwd, and keep `:workspace_roots` deny-read glob
    patterns symbolic until the actual roots are known.
    
    3. Review `codex-rs/protocol/src/permissions.rs` and
    `codex-rs/protocol/src/models.rs`.
    These add the policy/profile materialization helpers that expand exact
    `:workspace_roots` entries and scoped deny-read globs over every
    workspace root. This is also where `ActivePermissionProfileModification`
    is removed from the core model.
    
    4. Review the legacy bridge in
    `Config::load_from_base_config_with_overrides` and
    `Config::set_legacy_sandbox_policy`.
    This is where legacy `workspace-write` roots become runtime workspace
    roots, while Codex internal writable roots stay internal and do not
    appear as user-facing workspace roots.
    
    5. Then skim downstream call sites.
    The interesting pattern is raw-vs-effective access: state/proxy/bwrap
    paths keep the raw constrained profile, while execution, summaries, and
    user-visible status use the effective profile and workspace-root list.
    
    ## What Changed
    
    - added `[permissions.<id>.workspace_roots]` to the config model and
    schema
    - added runtime `workspace_roots` state to `Config`/`Permissions` and
    `ConfigOverrides`
    - made `Permissions` profile fields private and replaced direct mutation
    with accessors/setters
    - added `PermissionProfile` and `FileSystemSandboxPolicy` helpers for
    materializing `:workspace_roots` exact paths and deny-read globs across
    all roots
    - moved legacy additional writable roots into runtime workspace-root
    state instead of active profile modifications
    - removed `ActivePermissionProfileModification` and its app-server
    protocol/schema export
    - updated sandbox/status summary paths so internal writable roots are
    not reported as user workspace roots
    
    ## Verification Strategy
    
    The targeted tests cover the behavior at the layers where regressions
    are most likely:
    - `codex-rs/core/src/config/config_tests.rs` verifies config loading,
    legacy workspace-root seeding, effective profile materialization, and
    memory-root handling.
    - `codex-rs/core/src/config/permissions_tests.rs` verifies profile
    `workspace_roots` parsing and `:workspace_roots` scoped/glob
    compilation.
    - `codex-rs/protocol/src/permissions.rs` unit tests verify exact and
    glob materialization over multiple workspace roots.
    - `codex-rs/tui/src/status/tests.rs` and
    `codex-rs/utils/sandbox-summary/src/sandbox_summary.rs` verify the
    user-facing summaries show effective workspace roots and hide internal
    writes.
    
    I also ran `cargo check --tests` locally after the latest stack refresh
    to catch cross-crate API breakage from the private-field/accessor
    changes.

  • Trim TUI legacy core helper usage (#22695)
    ## Why
    
    The TUI still had a few low-risk dependencies flowing through the
    transitional `legacy_core` namespace after the app-server migration.
    These helpers either already have clearer non-core owners or are
    presentation logic that does not belong in `codex-core`, so moving them
    out reduces the compatibility surface without changing product behavior.
    
    ## What changed
    
    This is a low-risk change, almost completely mechanical in nature.
    
    - Route TUI Codex-home lookup through `codex-utils-home-dir`, use
    `Config::log_dir` directly, and call
    `codex-sandboxing::system_bwrap_warning` without going through
    `legacy_core`.
    - Move shared `codex resume` hint formatting from `codex-core` into
    `codex-utils-cli`.
    - Update CLI and TUI call sites to use the shared CLI utility, and keep
    the resume-command behavior covered by tests in its new home.
    
    ## Verification
    
    - `cargo test -p codex-utils-cli`
    - `cargo test -p codex-utils-cli resume_command`
  • feat: add layered --profile-v2 config files (#17141)
    ## Why
    
    `--profile-v2 <name>` gives launchers and runtime entry points a named
    profile config without making each profile duplicate the base user
    config. The base `$CODEX_HOME/config.toml` still loads first, then
    `$CODEX_HOME/<name>.config.toml` layers above it and becomes the active
    writable user config for that session.
    
    That keeps shared defaults, plugin/MCP setup, and managed/user
    constraints in one place while letting a named profile override only the
    pieces that need to differ.
    
    ## What Changed
    
    - Added the shared `--profile-v2 <name>` runtime option with validated
    plain names, now represented by `ProfileV2Name`.
    - Extended config layer state so the base user config and selected
    profile config are both `User` layers; APIs expose the active user layer
    and merged effective user config.
    - Threaded profile selection through runtime entry points: `codex`,
    `codex exec`, `codex review`, `codex resume`, `codex fork`, and `codex
    debug prompt-input`.
    - Made user-facing config writes go to the selected profile file when
    active, including TUI/settings persistence, app-server config writes,
    and MCP/app tool approval persistence.
    - Made plugin, marketplace, MCP, hooks, and config reload paths read
    from the merged user config so base and profile layers both participate.
    - Updated app-server config layer schemas to mark profile-backed user
    layers.
    
    ## Limits
    
    `--profile-v2` is still rejected for config-management subcommands such
    as feature, MCP, and marketplace edits. Those paths remain tied to the
    base `config.toml` until they have explicit profile-selection semantics.
    
    Some adjacent background writes may still update base or global state
    rather than the selected profile:
    
    - marketplace auto-upgrade metadata
    - automatic MCP dependency installs from skills
    - remote plugin sync or uninstall config edits
    - personality migration marker/default writes
    
    ## Verification
    
    Added targeted coverage for profile name validation, layer
    ordering/merging, selected-profile writes, app-server config writes,
    session hot reload, plugin config merging, hooks/config fixture updates,
    and MCP/app approval persistence.

  • config: add strict config parsing (#20559)
    ## Why
    
    Codex intentionally ignores unknown `config.toml` fields by default so
    older and newer config files keep working across versions. That leniency
    also makes typo detection hard because misspelled or misplaced keys
    disappear silently.
    
    This change adds an opt-in strict config mode so users and tooling can
    fail fast on unrecognized config fields without changing the default
    permissive behavior.
    
    This feature is possible because `serde_ignored` exposes the exact
    signal Codex needs: it lets Codex run ordinary Serde deserialization
    while recording fields Serde would otherwise ignore. That avoids
    requiring `#[serde(deny_unknown_fields)]` across every config type and
    keeps strict validation opt-in around the existing config model.
    
    ## What Changed
    
    ### Added strict config validation
    
    - Added `serde_ignored`-based validation for `ConfigToml` in
    `codex-rs/config/src/strict_config.rs`.
    - Combined `serde_ignored` with `serde_path_to_error` so strict mode
    preserves typed config error paths while also collecting fields Serde
    would otherwise ignore.
    - Added strict-mode validation for unknown `[features]` keys, including
    keys that would otherwise be accepted by `FeaturesToml`'s flattened
    boolean map.
    - Kept typed config errors ahead of ignored-field reporting, so
    malformed known fields are reported before unknown-field diagnostics.
    - Added source-range diagnostics for top-level and nested unknown config
    fields, including non-file managed preference source names.
    
    ### Kept parsing single-pass per source
    
    - Reworked file and managed-config loading so strict validation reuses
    the already parsed `TomlValue` for that source.
    - For actual config files and managed config strings, the loader now
    reads once, parses once, and validates that same parsed value instead of
    deserializing multiple times.
    - Validated `-c` / `--config` override layers with the same
    base-directory context used for normal relative-path resolution, so
    unknown override keys are still reported when another override contains
    a relative path.
    
    ### Scoped `--strict-config` to config-heavy entry points
    
    - Added support for `--strict-config` on the main config-loading entry
    points where it is most useful:
      - `codex`
      - `codex resume`
      - `codex fork`
      - `codex exec`
      - `codex review`
      - `codex mcp-server`
      - `codex app-server` when running the server itself
      - the standalone `codex-app-server` binary
      - the standalone `codex-exec` binary
    - Commands outside that set now reject `--strict-config` early with
    targeted errors instead of accepting it everywhere through shared CLI
    plumbing.
    - `codex app-server` subcommands such as `proxy`, `daemon`, and
    `generate-*` are intentionally excluded from the first rollout.
    - When app-server strict mode sees invalid config, app-server exits with
    the config error instead of logging a warning and continuing with
    defaults.
    - Introduced a dedicated `ReviewCommand` wrapper in `codex-rs/cli`
    instead of extending shared `ReviewArgs`, so `--strict-config` stays on
    the outer config-loading command surface and does not become part of the
    reusable review payload used by `codex exec review`.
    
    ### Coverage
    
    - Added tests for top-level and nested unknown config fields, unknown
    `[features]` keys, typed-error precedence, source-location reporting,
    and non-file managed preference source names.
    - Added CLI coverage showing invalid `--enable`, invalid `--disable`,
    and unknown `-c` overrides still error when `--strict-config` is
    present, including compound-looking feature names such as
    `multi_agent_v2.subagent_usage_hint_text`.
    - Added integration coverage showing both `codex app-server
    --strict-config` and standalone `codex-app-server --strict-config` exit
    with an error for unknown config fields instead of starting with
    fallback defaults.
    - Added coverage showing unsupported command surfaces reject
    `--strict-config` with explicit errors.
    
    ## Example Usage
    
    Run Codex with strict config validation enabled:
    
    ```shell
    codex --strict-config
    ```
    
    Strict config mode is also available on the supported config-heavy
    subcommands:
    
    ```shell
    codex --strict-config exec "explain this repository"
    codex review --strict-config --uncommitted
    codex mcp-server --strict-config
    codex app-server --strict-config --listen off
    codex-app-server --strict-config --listen off
    ```
    
    For example, if `~/.codex/config.toml` contains a typo in a key name:
    
    ```toml
    model = "gpt-5"
    approval_polic = "on-request"
    ```
    
    then `codex --strict-config` reports the misspelled key instead of
    silently ignoring it. The path is shortened to `~` here for readability:
    
    ```text
    $ codex --strict-config
    Error loading config.toml:
    ~/.codex/config.toml:2:1: unknown configuration field `approval_polic`
      |
    2 | approval_polic = "on-request"
      | ^^^^^^^^^^^^^^
    ```
    
    Without `--strict-config`, Codex keeps the existing permissive behavior
    and ignores the unknown key.
    
    Strict config mode also validates ad-hoc `-c` / `--config` overrides:
    
    ```text
    $ codex --strict-config -c foo=bar
    Error: unknown configuration field `foo` in -c/--config override
    
    $ codex --strict-config -c features.foo=true
    Error: unknown configuration field `features.foo` in -c/--config override
    ```
    
    Invalid feature toggles are rejected too, including values that look
    like nested config paths:
    
    ```text
    $ codex --strict-config --enable does_not_exist
    Error: Unknown feature flag: does_not_exist
    
    $ codex --strict-config --disable does_not_exist
    Error: Unknown feature flag: does_not_exist
    
    $ codex --strict-config --enable multi_agent_v2.subagent_usage_hint_text
    Error: Unknown feature flag: multi_agent_v2.subagent_usage_hint_text
    ```
    
    Unsupported commands reject the flag explicitly:
    
    ```text
    $ codex --strict-config cloud list
    Error: `--strict-config` is not supported for `codex cloud`
    ```
    
    ## Verification
    
    The `codex-cli` `strict_config` tests cover invalid `--enable`, invalid
    `--disable`, the compound `multi_agent_v2.subagent_usage_hint_text`
    case, unknown `-c` overrides, app-server strict startup failure through
    `codex app-server`, and rejection for unsupported commands such as
    `codex cloud`, `codex mcp`, `codex remote-control`, and `codex
    app-server proxy`.
    
    The config and config-loader tests cover unknown top-level fields,
    unknown nested fields, unknown `[features]` keys, source-location
    reporting, non-file managed config sources, and `-c` validation for keys
    such as `features.foo`.
    
    The app-server test suite covers standalone `codex-app-server
    --strict-config` startup failure for an unknown config field.
    
    ## Documentation
    
    The Codex CLI docs on developers.openai.com/codex should mention
    `--strict-config` as an opt-in validation mode for supported
    config-heavy entry points once this ships.
  • feat(tui): remove Zellij TUI workarounds (#22214)
    ## Why
    
    We added Zellij-specific TUI workarounds because older Zellij behavior
    did not work with Codex's normal terminal model:
    
    - #8555 made `tui.alternate_screen = "auto"` disable alternate screen in
    Zellij so transcript history stayed available.
    - #16578 avoided scroll-region operations in Zellij by emitting raw
    newlines and using a separate composer styling path.
    
    This PR removes both workarounds because the latest Zellij release
    tested locally (`zellij 0.44.1`) works correctly with Codex's standard
    TUI behavior: normal alternate-screen handling, redraw, and history
    insertion.
    
    ## What Changed
    
    - Removed the `InsertHistoryMode::Zellij` path and the Zellij-only
    newline scrollback insertion behavior.
    - Removed cached `is_zellij` state from the TUI and composer.
    - Removed Zellij-specific composer styling, the helper snapshot, and the
    `TerminalInfo::is_zellij()` convenience method that only served this
    workaround.
    - Changed `tui.alternate_screen = "auto"` to use alternate screen for
    Zellij too; `--no-alt-screen` and `tui.alternate_screen = "never"` still
    preserve the inline mode escape hatch.
    - Updated the generated config schema description for
    `tui.alternate_screen`.
    
    ## How to Test
    
    Manual smoke path used with `zellij 0.44.1`:
    
    1. Build and run this branch inside a Zellij `0.44.1` session with
    default config.
    2. Start Codex normally and produce enough assistant/tool output to
    create scrollback.
    3. Confirm the transcript remains readable, the composer renders
    normally, and scrolling through terminal history works.
    4. Resize the Zellij pane while output exists and confirm the TUI
    redraws without duplicated, missing, or stale rows.
    5. Compare with `--no-alt-screen` or `-c tui.alternate_screen=never` if
    you want to verify the inline fallback still works.
    
    Targeted tests:
    - `just write-config-schema`
    - `just fmt`
    - `just fix -p codex-tui`
    - `cargo test -p codex-terminal-detection`
    - `cargo test -p codex-tui alternate_screen_auto_uses_alt_screen`
    
    Attempted but did not complete locally:
    - `cargo test -p codex-tui` built and ran the new test successfully,
    then failed later on unrelated local failures in
    `status_permissions_full_disk_managed_*` and a stack overflow in
    `tests::fork_last_filters_latest_session_by_cwd_unless_show_all`.
    
    ## Documentation
    
    No developers.openai.com Codex documentation update is needed for this
    revert.
  • add --dangerously-bypass-hook-trust CLI flag (#21768)
    # Why
    
    Hook trust happens through the TUI in `/hooks` so it can block
    non-interactive use cases. This flag will allow users that are using
    codex headlessly to bypass hooks when they want to.
    
    # What
    
    This adds one invocation-scoped escape hatch.
    
    - the CLI flag sets a runtime-only `bypass_hook_trust` override; there
    is no durable `config.toml` setting
    - hook discovery still respects normal enablement, so explicitly
    disabled hooks remain disabled
    - we show a `--dangerously-bypass-hook-trust is enabled. Enabled hooks
    may run without review for this invocation.` message on startup so
    accidental use is visible in both interactive and exec flows
    
    This keeps “enabled” and “trusted” as separate concepts in the normal
    path, while giving CI/E2E callers a stable way to opt into the
    exceptional path when they already control the hook set.
  • Add support for UDS in codex --remote (#22414)
    ## Why
    
    Added support for UDS connections in `codex --remote`.
    
    TUI also now connects to local app-server using UDS by default if it is
    running and set to listen to UDS connection.
    
    ## What Changed
    
    - Introduced `RemoteAppServerEndpoint` with `WebSocket` and `UnixSocket`
    variants.
    - Reused the existing JSON-RPC-over-WebSocket protocol over either a TCP
    WebSocket stream or a UDS stream.
    - Updated `codex --remote` to accept `ws://host:port`,
    `wss://host:port`, `unix://`, and `unix://PATH`.
    - Kept `--remote-auth-token-env` restricted to `wss://` and loopback
    `ws://` remotes.
    - Added a fast TUI startup probe for the default daemon socket, falling
    back to the embedded app server when the daemon is absent or
    unresponsive.
    
    ## Verification
    
    - Manually verified that the updated remote flow works.
    - Added coverage for UDS remote round trips, WebSocket auth headers,
    auth-token transport policy, remote address parsing, and missing-daemon
    fallback.
    - Ran focused remote test coverage locally.
  • feat(tui): add ambient terminal pets (#21206)
    ## Why
    
    The Codex App has animated pets, but the TUI had no equivalent ambient
    companion surface. This brings that experience into terminal Codex while
    keeping the main chat flow usable: the pet should feel present, but it
    cannot cover transcript text, composer input, approvals, or picker
    content.
    
    The feature also needs to be terminal-aware. Different terminals support
    different image protocols, tmux can interfere with image rendering, and
    some users will want pets disabled entirely or anchored differently
    depending on their layout.

    </table>
    
    ## What Changed
    
    - Add a TUI ambient pet renderer in `codex-rs/tui/src/pets/`.
    - Port the app-style pet animation states so the sprite changes with
    task status, waiting-for-input states, review/ready states, and
    failures.
    - Add `/pets` selection UI with a preview pane, loading state, built-in
    pet choices, and a first-row `Disable terminal pets` option.
    - Download built-in pet spritesheets on demand from the same public CDN
    path already used by Android, under
    `https://persistent.oaistatic.com/codex/pets/v1/...`, and cache them
    locally under `~/.codex/cache/tui-pets/`.
    - Keep custom pets local.
    - Add config support for pet selection, disabling pets, and choosing
    whether the pet follows the composer bottom or anchors to the terminal
    bottom.
    - Reserve layout space around the pet so transcript wrapping, live
    responses, and composer input do not render underneath the sprite.
    - Gate image rendering by terminal capability, disable image pets under
    tmux, and support both Kitty Graphics and SIXEL terminals.
    - Add redraw cleanup for terminal image artifacts, including sixel cell
    clearing.
    
    ## Current Scope
    
    - This is an initial TUI version of ambient pets, not full App parity.
    - It focuses on ambient sprite rendering, `/pets` selection, custom
    pets, terminal capability gating, and on-demand CDN-backed built-in
    assets.
    - The ambient text overlay is currently disabled, so the TUI renders the
    pet sprite without extra status text beside it.
    
    ## How to Test
    
    1. Start Codex TUI in a terminal with image support.
    2. Run `/pets`.
    3. Confirm the picker shows built-in pets plus custom pets, and the
    first item is `Disable terminal pets`.
    4. On a fresh `~/.codex/cache/tui-pets/`, move onto a built-in pet and
    confirm the first preview downloads the spritesheet from the shared
    Codex pets CDN and renders successfully.
    5. Move through the pet list and confirm subsequent built-in previews
    use the local cache.
    6. Select a pet, then send and receive messages. Confirm transcript and
    composer text wrap before the pet instead of rendering underneath the
    sprite.
    7. Change the pet anchor setting and confirm the pet can either follow
    the composer bottom or sit at the terminal bottom.
    8. Return to `/pets`, choose `Disable terminal pets`, and confirm the
    sprite disappears cleanly.
    
    Targeted tests:
    - `cargo test -p codex-tui ambient_pet_`
    - `cargo test -p codex-tui
    resize_reflow_wraps_transcript_early_when_pet_is_enabled`
    - `cargo insta pending-snapshots`
  • Add process-scoped SQLite telemetry (#22154)
    ## Summary
    - add SQLite init, backfill-gate, and fallback telemetry without
    introducing a cross-cutting state-db access wrapper
    - install one process-scoped telemetry sink after OTEL startup and let
    low-level state/rollout paths emit through it directly
    - add process-start metrics for the process owners that initialize
    SQLite

  • feat(tui): render responsive Markdown tables in TUI (#22052)
    ## Why
    
    The TUI currently treats Markdown tables as ordinary wrapped text, which
    makes table-heavy responses hard to read and brittle across narrow panes
    and terminal resizes.
    
    This change teaches the TUI to render Markdown tables responsively while
    preserving the raw Markdown source needed to re-render streamed and
    finalized transcript content after width changes. The goal is to keep
    tables legible during streaming, after resize, and once a turn has
    finished, without corrupting scrollback ordering.
    
    ## What Changed
    
    - add table detection and responsive table rendering in the Markdown
    renderer
    - render standard tables with Unicode box-drawing borders when the pane
    is wide enough
    - add a vertical readability fallback for constrained or dense tables so
    narrow panes still show each row clearly
    - keep links and `<br>` content inside table cells instead of leaking
    text outside the table
    - avoid table normalization inside fenced or indented code blocks
    - preserve raw streamed Markdown source and keep the active table as a
    mutable tail until finalization
    - consolidate finalized streamed content into source-backed transcript
    cells so post-resize re-rendering stays correct
    - add snapshot and targeted streaming/resize regression coverage for the
    new table behavior
    
    ## How to Test
    
    1. Start Codex TUI from this branch.
    2. Paste this exact prompt:
    `This is a session to test codex, no need to do any thinking, just end
    different markdown tables, with columns exploring different markdown
    contents, like links, bold italic, code, etc. Make them different sizes,
    some 30+ rows, some not and intertwine them with some paragraphs with
    complex formatting as well.`
    3. Confirm the response includes several Markdown tables mixed with
    richly formatted paragraphs.
    4. Confirm wide-enough tables render with box-drawing borders instead of
    plain wrapped pipe text.
    5. Resize the terminal narrower while the answer is still streaming and
    confirm the in-progress table stays coherent instead of duplicating
    headers or leaving broken scrollback behind.
    6. Resize again after the turn finishes and confirm the finalized
    transcript re-renders cleanly at the new width.
    7. In a narrow pane, verify dense tables fall back to the vertical
    per-row layout instead of producing unreadable wrapped columns.
    8. Also verify pipe-heavy fenced code blocks still render as code, not
    as tables.
    
    Targeted tests:
    - `cargo test -p codex-tui table_readability_fallback --no-fail-fast`
    - `cargo test -p codex-tui markdown_render --no-fail-fast`
    - `cargo test -p codex-tui streaming::controller --no-fail-fast`
    - `cargo test -p codex-tui table_resize_lifecycle --no-fail-fast`
