## Why Recovered answer history needs presentation instructions alongside the moderation flag so clients can apply the intended display behavior. ## What changed - Add optional `display` metadata with an `action` and optional `blockType`, `cyberTrustedAccess`, and `checkTrustedContacts` fields. - Carry display metadata through final answers, legacy events, thread history reconstruction, and legacy rollout migration. - Expose the metadata in the app-server protocol and update generated JSON schemas, TypeScript types, and Python SDK models. Missing display fields remain compatible with existing stored moderation data; the app-server emits absent optional values as `null`. ## Testing Extend the final-answer moderation test to cover display metadata in answer items and legacy events. Add serialization coverage for missing display data, nullable fields, and preservation of an explicit `false` value. GitOrigin-RevId: b798a2ecc53c2a94c7659ef3d9663b3143b70a1a
Thread Store
codex-thread-store is the storage boundary for Codex threads. It defines the
ThreadStore trait plus local and in-memory implementations. Other storage
implementations may live outside this repository.
Responsibilities
ThreadStore::append_itemsis the raw canonical history append API. It does not infer metadata from item contents.ThreadStore::update_thread_metadatais the only thread metadata write API. It accepts a single literal metadata patch shape, regardless of whether the caller is applying a user/API mutation or facts derived above the store from appended history.LiveThreadis the preferred API for active session persistence. It owns a per-thread metadata sync helper, applies the rollout persistence policy, appends canonical history, and then sends metadata patches throughThreadStore::update_thread_metadata.ThreadManagerroutes metadata mutations for loaded and cold threads through one entrypoint. Loaded threads use theirLiveThread; cold threads go directly to the store.LocalThreadStorepersists history throughcodex-rolloutJSONL files and persists queryable metadata through the SQLite state database when available. Local explicit metadata mutations also maintain JSONL/name-index compatibility so reading old or SQLite-less local storage keeps working.RolloutRecorderis the local JSONL writer. It writes already-canonical items forThreadStore::append_items; it no longer decides metadata updates for live thread-store appends.core/sessioncreates or resumesLiveThreadhandles and does not need to know whether persistence is backed by local files or another store.
Direction
New metadata observation semantics should live above ThreadStore. Stores
persist explicit metadata fields, but raw history appends remain history-only.
