• [codex] Add user input client ids (#24653)

  ## Summary
  
  Adds an optional `clientId` field to app-server v2 `UserInput` and
  carries it through the core `UserInput` model so clients can correlate
  echoed user input items without relying on payload equality.
  
  ## Details
  
  - Adds `client_id: Option<String>` to core `UserInput` variants.
  - Exposes the v2 app-server field as `clientId` on the wire and in
  generated TypeScript.
  - Preserves the id when converting between app-server v2 and core
  protocol types.
  - Regenerates app-server schema fixtures.
  
  ## Validation
  
  - `just fmt`
  - `just write-app-server-schema`
  - `cargo test -p codex-app-server-protocol`
  - `cargo test -p codex-protocol`
  - `just fix -p codex-app-server-protocol`
  - `just fix -p codex-protocol`
  - `git diff --check`

• Add trace_id to TurnStartedEvent (#23980)

  ## Why
  [Recent PR](https://github.com/openai/codex/pull/22709) removed
  `trace_id` from `TurnContextItem`.
  
  ## What changed
  - Add to `TurnStartedEvent` so rollout consumers can correlate turns
  with telemetry traces.
  - Note that the branch name is out of date because I originally re-added
  to `TurnContextItem`, but we decided to move it to `TurnStartedEvent`.
  
  ## Verification
  - `cargo test -p codex-protocol`
  - `cargo test -p codex-core --lib
  regular_turn_emits_turn_started_without_waiting_for_startup_prewarm`
  - `cargo test -p codex-core --test all
  emits_warning_when_resumed_model_differs`
  - `cargo test -p codex-rollout`
  - `cargo test -p codex-state`

• Preserve image detail in app-server inputs (#20693)

  ## Summary
  
  - Add optional image detail to user image inputs across core, app-server
  v2, thread history/event mapping, and the generated app-server
  schemas/types.
  - Preserve requested detail when serializing Responses image inputs:
  omitted detail stays on the existing `high` default, while explicit
  `original` keeps local images on the original-resolution path.
  - Support `high`/`original` consistently for tool image outputs,
  including MCP `codex/imageDetail`, code-mode image helpers, and
  `view_image`.

• Import external agent sessions in background (#20284)

  Summary:
  - Return from external agent import before session history import
  finishes
  - Run session import work in the background and emit the existing
  completion notification when it is done
  - Serialize session imports so duplicate requests do not create
  duplicate imported threads
  
  Verification:
  - cargo test -p codex-app-server external_agent_config_
  - cargo test -p codex-external-agent-sessions
  - just fix -p codex-app-server
  - just fix -p codex-external-agent-sessions
  - git diff --check

• Consume ai-title from external sessions and add end marker (#20261)

  ## Summary
  - Support Claude Code `ai-title` / `aiTitle` records when detecting and
  importing external agent sessions.
  - Preserve existing `custom-title` / `customTitle` precedence; only fall
  back to `aiTitle` when no custom title is present.
  - Add coverage for both detection and import title selection, including
  the custom-title-over-ai-title case.
  
  ## Testing
  - `cargo test -p codex-external-agent-sessions`
  - `just fix -p codex-external-agent-sessions`

• External agent session support (#19895)

  ## Summary
  
  This extends external agent detection/import beyond config artifacts so
  Codex can detect recent sessions files from the external agent home and
  import them into Codex rollout history.
  
  ## What changed
  
  - Added a focused `external_agent_sessions` module for:
    - session discovery
    - source-record parsing
    - rollout construction
    - import ledger tracking
  - Wired session detection/import into the app-server external agent
  config API.
  - Added compaction handling so large imported sessions can be resumed
  safely before the first follow-up turn.
  
  ## Testing
  
  Added coverage for:
  - recent-session detection
  - custom-title handling
  - recency filtering
  - dedupe and re-detect-after-source-change behavior
  - visible imported turn construction
  - backward-compatible import payload deserialization
  - end-to-end RPC import flow
  - rejection of undetected session paths
  - repeat-import behavior
  - large-session compaction before first follow-up
  
  Ran:
  - `cargo test -p codex-app-server external_agent_config_import_ --test
  all`
