## What changed
- Mark `api_key_model_discovery` as stable and enable it by default, while preserving explicit user opt-outs and provider catalog requirements.
- Fall back to bundled models when discovery is disabled at runtime, including when a remote catalog has already been loaded.
## Testing
Extend model-list coverage for default enablement, app overrides, and user configuration precedence. Add a regression assertion that runtime opt-outs hide loaded catalogs without additional fetches, and update daemon compatibility tests for the new default.

## Why
Opening a separate-window editor from the fullscreen TUI leaves the alternate screen, hiding the draft and the instruction to save and close the editor.
## What changed
Preserve and repaint the last Codex frame when handing the terminal to an external editor, while releasing keyboard and mouse input modes. Track whether the alternate screen's keyboard mode is active so cleanup does not pop it twice if the editor switches screens. Restore TUI modes and the alternate screen when the editor returns.
## Testing
Add terminal integration coverage for separate-window editors, terminal editors that switch or reuse screens, and inline mode. Verify the visible draft and handoff hint, disabled mouse reporting, edited draft recovery, and continued typing. Add a unit test for balanced keyboard stacks whether or not the editor leaves the alternate screen.

## Why
Automatic daemon launches could silently fall back to embedded mode when shared feature settings differed from the session's requirements. Changing those settings affects other clients, and restarting the server may interrupt active or queued work.
## What changed
- Offer interactive choices to run without the daemon, restart with the required settings, or cancel. Default to cancel and require explicit confirmation for restart.
- Allow restart only for managed daemons with a feature mismatch, then recheck compatibility once. Noninteractive required-daemon failures return an error with `--no-daemon` guidance; optional attachment retains its fallback behavior.
- Preserve saved feature overrides on startup and require confirmation before applying requested shared-feature disables, including on fresh starts.
- Merge confirmed settings under the lifecycle lock, persist changes after the old process stops, and avoid restarting when the saved overrides already match.
## Testing
Add recovery-menu snapshots and confirmation tests, compatibility tests for required and optional attachment, daemon ownership and settings-preservation tests, and CLI terminal tests for cancellation, embedded fallback, confirmed restart, and disabling shared features.

## Why
Feature overrides previously forced embedded mode even when they could work with the shared daemon. A running daemon can also have different feature settings from the current invocation, including when the invocation uses defaults.
## What changed
- Allow selected Boolean feature overrides and `suppress_unstable_features_warning` in daemon mode. Keep explicit overrides that disable shared services in embedded mode.
- Pass shared-service feature overrides to newly launched daemons and persist them for restarts and updates without changing a running daemon's settings.
- Check daemon feature settings with `experimentalFeature/list` before attaching. Warn and fall back to embedded mode on mismatches, failed checks, or an incompatible code-mode host fallback policy. Skip this check for the agents overview.
- Resolve worktree configuration before daemon selection and allow worktree sessions to auto-start the daemon.
- Forward `suppress_unstable_features_warning` in thread configuration overrides.
## Testing
Add coverage for override eligibility and precedence, launch-feature persistence and reuse, and TUI fallback warnings for feature and host-policy mismatches. Extend worktree integration coverage to exercise daemon auto-start and warning suppression.

## What changed
- Add `features.daemon_auto_start`, disabled by default and available through `/experimental`, to start the shared local server for eligible new, resumed, and forked sessions. Changes take effect on the next launch, and disabling the feature persists an explicit `false`.
- Require successful daemon startup and connection when auto-start applies. On failure, show guidance to rerun the same command with `--no-daemon` instead of silently falling back to an embedded server.
- Preserve embedded mode for excluded launches, including Bedrock sign-in, and carry exclusion warnings through resume and fork pickers. Honor `--no-daemon` without an exclusion warning.
- Update `/import` guidance to recommend restarting with `codex --no-daemon`.
## Testing
Add CLI and TUI coverage for automatic daemon attachment, startup and connection failures, `--no-daemon`, picker warning persistence, and Bedrock onboarding with and without a running daemon. Add snapshots and configuration-write assertions for the experimental toggle.
