• feat: sqlite 1 (#10004)

  Add a `.sqlite` database to be used to store rollout metatdata (and
  later logs)
  This PR is phase 1:
  * Add the database and the required infrastructure
  * Add a backfill of the database
  * Persist the newly created rollout both in files and in the DB
  * When we need to get metadata or a rollout, consider the `JSONL` as the
  source of truth but compare the results with the DB and show any errors

• feat(core) RequestRule (#9489)

  ## Summary
  Instead of trying to derive the prefix_rule for a command mechanically,
  let's let the model decide for us.

• fix: enable per-turn updates to web search mode (#10040)

  web_search can now be updated per-turn, for things like changes to
  sandbox policy.
  
  `SandboxPolicy::DangerFullAccess` now sets web_search to `live`, and the
  default is still `cached`.
  
  Added integration tests.

• fix: handle all web_search actions and in progress invocations (#9960)

  ### Summary
  - Parse all `web_search` tool actions (`search`, `find_in_page`,
  `open_page`).
  - Previously we only parsed + displayed `search`, which made the TUI
  appear to pause when the other actions were being used.
  - Show in progress `web_search` calls as `Searching the web`
    - Previously we only showed completed tool calls

• Reject request_user_input outside Plan/Pair (#9955)

  ## Context
  
  Previous work in https://github.com/openai/codex/pull/9560 only rejected
  `request_user_input` in Execute and Custom modes. Since then, additional
  modes
  (e.g., Code) were added, so the guard should be mode-agnostic.
  
  ## What changed
  
  - Switch the handler to an allowlist: only Plan and PairProgramming are
  allowed
  - Return the same error for any other mode (including Code)
  - Add a Code-mode rejection test alongside the existing Execute/Custom
  tests
  
  ## Why
  
  This prevents `request_user_input` from being used in modes where it is
  not
  intended, even as new modes are introduced.

• Add MCP server scopes config and use it as fallback for OAuth login (#9647)

  ### Motivation
  - Allow MCP OAuth flows to request scopes defined in `config.toml`
  instead of requiring users to always pass `--scopes` on the CLI.
  CLI/remote parameters should still override config values.
  
  ### Description
  - Add optional `scopes: Option<Vec<String>>` to `McpServerConfig` and
  `RawMcpServerConfig`, and propagate it through deserialization and the
  built config types.
  - Serialize `scopes` into the MCP server TOML via
  `serialize_mcp_server_table` in `core/src/config/edit.rs` and include
  `scopes` in the generated config schema (`core/config.schema.json`).
  - CLI: update `codex-rs/cli/src/mcp_cmd.rs` `run_login` to fall back to
  `server.scopes` when the `--scopes` flag is empty, with explicit CLI
  scopes still taking precedence.
  - App server: update
  `codex-rs/app-server/src/codex_message_processor.rs`
  `mcp_server_oauth_login` to use `params.scopes.or_else(||
  server.scopes.clone())` so the RPC path also respects configured scopes.
  - Update many test fixtures to initialize the new `scopes` field (set to
  `None`) so test code builds with the new struct field.
  
  ### Testing
  - Ran config tooling and formatters: `just write-config-schema`
  (succeeded), `just fmt` (succeeded), and `just fix -p codex-core`, `just
  fix -p codex-cli`, `just fix -p codex-app-server` (succeeded where
  applicable).
  - Ran unit tests for the CLI: `cargo test -p codex-cli` (passed).
  - Ran unit tests for core: `cargo test -p codex-core` (ran; many tests
  passed but several failed, including model refresh/403-related tests,
  shell snapshot/timeouts, and several `unified_exec` expectations).
  - Ran app-server tests: `cargo test -p codex-app-server` (ran; many
  integration-suite tests failed due to mocked/remote HTTP 401/403
  responses and wiremock expectations).
  
  If you want, I can split the tests into smaller focused runs or help
  debug the failing integration tests (they appear to be unrelated to the
  config change and stem from external HTTP/mocking behaviors encountered
  during the test runs).

• Add thread/unarchive to restore archived rollouts (#9843)

  ## Summary
  - Adds a new `thread/unarchive` RPC to move archived thread rollouts
  back into the active `sessions/` tree.
  
  ## What changed
  - **Protocol**
    - Adds `thread/unarchive` request/response types and wiring.
  - **Server**
    - Implements `thread_unarchive` in the app server.
    - Validates the archived rollout path and thread ID.
  - Restores the rollout to `sessions/YYYY/MM/DD/...` based on the rollout
  filename timestamp.
  - **Core**
  - Adds `find_archived_thread_path_by_id_str` helper for archived
  rollouts.
  - **Docs**
    - Documents the new RPC and usage example.
  - **Tests**
    - Adds an end-to-end server test that:
      1) starts a thread,
      2) archives it,
      3) unarchives it,
      4) asserts the file is restored to `sessions/`.
  
  ## How to use
  ```json
  { "method": "thread/unarchive", "id": 24, "params": { "threadId": "<thread-id>" } }
  ```
  
  ## Author Codex Session
  
  `codex resume 019bf158-54b6-7960-a696-9d85df7e1bc1` (soon I'll make this
  kind of session UUID forkable by anyone with the right
  `session_object_storage_url` line in their config, but for now just
  pasting it here for my reference)

• feat(tui) /personality (#9718)

  ## Summary
  Adds /personality selector in the TUI, which leverages the new core
  interface in #9644
  
  Notes:
  - We are doing some of our own state management for model_info loading
  here, but not sure if that's ideal. open to opinions on simpler
  approach, but would like to avoid blocking on a larger refactor
  - Right now, the `/personality` selector just hides when the model
  doesn't support it. we can update this behavior down the line
  
  ## Testing
  - [x] Tested locally
  - [x] Added snapshot tests

• Reduce burst testing flake (#9549)

  ## Summary
  
  - make paste-burst tests deterministic by injecting explicit timestamps
  instead of relying on wall clock timing
  - add time-aware helpers for input/submission paths so tests can drive
  the burst heuristic precisely
  - update burst-related tests to flush using computed timeouts while
  preserving behavior assertions
  - increase timeout slack in
  shell_tools_start_before_response_completed_when_stream_delayed to
  reduce flakiness

• Add collaboration_mode to TurnContextItem (#9583)

  ## Summary
  - add optional `collaboration_mode` to `TurnContextItem` in rollouts
  - persist the current collaboration mode when recording turn context
  (sampling + compaction)
  
  ## Rationale
  We already persist turn context data for resume logic. Capturing
  collaboration mode in the rollout gives us the mode context for each
  turn, enabling follow‑up work to diff mode instructions correctly on
  resume.
  
  ## Changes
  - protocol: add optional `collaboration_mode` field to `TurnContextItem`
  - core: persist collaboration mode alongside other turn context settings
  in rollouts

  - Add a session accessor for current collaboration mode and enforce the
  gate in the request_user_input handler.
  - Update core/app-server tests to use Plan mode for success and add
  Execute/Custom rejection coverage.

• Add total (non-partial) TextElement placeholder accessors (#9545)

  ## Summary
  - Make `TextElement` placeholders private and add a text-backed accessor
  to avoid assuming `Some`.
  - Since they are optional in the protocol, we want to make sure any
  accessors properly handle the None case (getting the placeholder using
  the byte range in the text)
  - Preserve placeholders during protocol/app-server conversions using the
  accessor fallback.
  - Update TUI composer/remap logic and tests to use the new
  constructor/accessor.

• fix: prevent repeating interrupted turns (#9043)

  ## What
  Record a model-visible `<turn_aborted>` marker in history when a turn is
  interrupted, and treat it as a session prefix.
  
  ## Why
  When a turn is interrupted, Codex emits `TurnAborted` but previously did
  not persist anything model-visible in the conversation history. On the
  next user turn, the model can’t tell the previous work was aborted and
  may resume/repeat earlier actions (including duplicated side effects
  like re-opening PRs).
  
  Fixes: https://github.com/openai/codex/issues/9042
  
  ## How
  On `TurnAbortReason::Interrupted`, append a hidden user message
  containing a `<turn_aborted>…</turn_aborted>` marker and flush.
  Treat `<turn_aborted>` like `<environment_context>` for session-prefix
  filtering.
  Add a regression test to ensure follow-up turns don’t repeat side
  effects from an aborted turn.
  
  ## Testing
  `just fmt`
  `just fix -p codex-core`
  `cargo test -p codex-core -- --test-threads=1`
  `cargo test --all-features -- --test-threads=1`

• fix(core) Preserve base_instructions in SessionMeta (#9427)

  ## Summary
  This PR consolidates base_instructions onto SessionMeta /
  SessionConfiguration, so we ensure `base_instructions` is set once per
  session and should be (mostly) immutable, unless:
  - overridden by config on resume / fork
  - sub-agent tasks, like review or collab
  
  
  In a future PR, we should convert all references to `base_instructions`
  to consistently used the typed struct, so it's less likely that we put
  other strings there. See #9423. However, this PR is already quite
  complex, so I'm deferring that to a follow-up.
  
  ## Testing
  - [x] Added a resume test to assert that instructions are preserved. In
  particular, `resume_switches_models_preserves_base_instructions` fails
  against main.
  
  Existing test coverage thats assert base instructions are preserved
  across multiple requests in a session:
  - Manual compact keeps baseline instructions:
  core/tests/suite/compact.rs:199
  - Auto-compact keeps baseline instructions:
  core/tests/suite/compact.rs:1142
  - Prompt caching reuses the same instructions across two requests:
  core/tests/suite/prompt_caching.rs:150 and
  core/tests/suite/prompt_caching.rs:157
  - Prompt caching with explicit expected string across two requests:
  core/tests/suite/prompt_caching.rs:213 and
  core/tests/suite/prompt_caching.rs:222
  - Resume with model switch keeps original instructions:
  core/tests/suite/resume.rs:136
  - Compact/resume/fork uses request 0 instructions for later expected
  payloads: core/tests/suite/compact_resume_fork.rs:215

• chore(instructions) Remove unread SessionMeta.instructions field (#9423)

  ### Description
  - Remove the now-unused `instructions` field from the session metadata
  to simplify SessionMeta and stop propagating transient instruction text
  through the rollout recorder API. This was only saving
  user_instructions, and was never being read.
  - Stop passing user instructions into the rollout writer at session
  creation so the rollout header only contains canonical session metadata.
  
  ### Testing
  
  - Ran `just fmt` which completed successfully.
  - Ran `just fix -p codex-protocol`, `just fix -p codex-core`, `just fix
  -p codex-app-server`, `just fix -p codex-tui`, and `just fix -p
  codex-tui2` which completed (Clippy fixes applied) as part of
  verification.
  - Ran `cargo test -p codex-protocol` which passed (28 tests).
  - Ran `cargo test -p codex-core` which showed failures in a small set of
  tests (not caused by the protocol type change directly):
  `default_client::tests::test_create_client_sets_default_headers`,
  several `models_manager::manager::tests::refresh_available_models_*`,
  and `shell_snapshot::tests::linux_sh_snapshot_includes_sections` (these
  tests failed in this CI run).
  - Ran `cargo test -p codex-app-server` which reported several failing
  integration tests (including
  `suite::codex_message_processor_flow::test_codex_jsonrpc_conversation_flow`,
  `suite::output_schema::send_user_turn_*`, and
  `suite::user_agent::get_user_agent_returns_current_codex_user_agent`).
  - `cargo test -p codex-tui` and `cargo test -p codex-tui2` were
  attempted but aborted due to disk space exhaustion (`No space left on
  device`).

• Add collaboration_mode override to turns (#9408)

• feat(app-server, core): return threads by created_at or updated_at (#9247)

  Add support for returning threads by either `created_at` OR `updated_at`
  descending. Previously core always returned threads ordered by
  `created_at`.
  
  This PR:
  - updates core to be able to list threads by `updated_at` OR
  `created_at` descending based on what the caller wants
  - also update `thread/list` in app-server to expose this (default to
  `created_at` if not specified)
  
  All existing codepaths (app-server, TUI) still default to `created_at`,
  so no behavior change is expected with this PR.
  
  **Implementation**
  To sort by `updated_at` is a bit nontrivial (whereas `created_at` is
  easy due to the way we structure the folders and filenames on disk,
  which are all based on `created_at`).
  
  The most naive way to do this without introducing a cache file or sqlite
  DB (which we have to implement/maintain) is to scan files in reverse
  `created_at` order on disk, and look at the file's mtime (last modified
  timestamp according to the filesystem) until we reach `MAX_SCAN_FILES`
  (currently set to 10,000). Then, we can return the most recent N
  threads.
  
  Based on some quick and dirty benchmarking on my machine with ~1000
  rollout files, calling `thread/list` with limit 50, the `updated_at`
  path is slower as expected due to all the I/O:
  - updated-at: average 103.10 ms
  - created-at: average 41.10 ms
  
  Those absolute numbers aren't a big deal IMO, but we can certainly
  optimize this in a followup if needed by introducing more state stored
  on disk.
  
  **Caveat**
  There's also a limitation in that any files older than `MAX_SCAN_FILES`
  will be excluded, which means if a user continues a REALLY old thread,
  it's possible to not be included. In practice that should not be too big
  of an issue.
  
  If a user makes...
  - 1000 rollouts/day → threads older than 10 days won't show up
  - 100 rollouts/day → ~100 days
  
  If this becomes a problem for some reason, even more motivation to
  implement an updated_at cache.

• Turn-state sticky routing per turn (#9332)

  - capture the header from SSE/WS handshakes, store it per
  ModelClientSession using `Oncelock`, echo it on turn-scoped requests,
  and add SSE+WS integration tests for within-turn persistence +
  cross-turn reset.
  
  - keep `x-codex-turn-state` sticky within a user turn to maintain
  routing continuity for retries/tool follow-ups.

• Add text element metadata to protocol, app server, and core (#9331)

  The second part of breaking up PR
  https://github.com/openai/codex/pull/9116
  
  Summary:
  
  - Add `TextElement` / `ByteRange` to protocol user inputs and user
  message events with defaults.
  - Thread `text_elements` through app-server v1/v2 request handling and
  history rebuild.
  - Preserve UI metadata only in user input/events (not `ContentItem`)
  while keeping local image attachments in user events for rehydration.
  
  Details:
  
  - Protocol: `UserInput::Text` carries `text_elements`;
  `UserMessageEvent` carries `text_elements` + `local_images`.
  Serialization includes empty vectors for backward compatibility.
  - app-server-protocol: v1 defines `V1TextElement` / `V1ByteRange` in
  camelCase with conversions; v2 uses its own camelCase wrapper.
  - app-server: v1/v2 input mapping includes `text_elements`; thread
  history rebuilds include them.
  - Core: user event emission preserves UI metadata while model history
  stays clean; history replay round-trips the metadata.

• [search] allow explicitly disabling web search (#9249)

  moving `web_search` rollout serverside, so need a way to explicitly
  disable search + signal eligibility from the client.
  
  - Add `x‑oai‑web‑search‑eligible` header that signifies whether the
  request can have web search.
  - Only attach the `web_search` tool when the resolved `WebSearchMode` is
  `Live` or `Cached`.

  `web_search_cached`, `web_search_request`, and `tools.web_search`.
  
  Keep `--search` as live.
  
  ### Tests
  Added tests
