Implementation Status

Update this file before each feature commit.

Area	Status	Commit	Verification	Notes
Scaffold	Completed	fc47967	cargo fmt --check; cargo test; cargo clippy --all-targets --all-features --locked -- -D warnings	Rust crate, lint policy, pinned TLS-sensitive dependencies, .gitignore, and minimal entry points are in place.
API contract docs	Completed	fc47967	cargo fmt --check; cargo test; cargo clippy --all-targets --all-features --locked -- -D warnings	/v1/* OpenAI-compatible body, /admin/* frontend envelope, body codes, camelCase, and request ID policy are documented.
Configuration	Completed	9ed8579 + e0680bf	cargo test default_config_keeps_only_codex_backend; cargo test config_loader_merges_default_local_and_cprs_env_overrides; full fmt/test/clippy before commit	Defines Codex-only config, default/local/env loading, default YAML, and Arc<AppServices> state shell.
SQLite storage	Completed	ffec8b5 + b0c10f2	cargo test sqlite_schema_creates_accounts_and_event_tables; cargo test connect_sqlite_creates_parent_directory_for_file_database; full fmt/test/clippy before commit	Creates SQLite WAL connector, parent directory bootstrap, sqlx-managed schema for accounts/API keys/sessions/cookies/fingerprints/events, and event/account indexes.
Admin auth and client API keys	Completed	24d5799 + 4e0d1e5	cargo test client_api_key_has_proxy_prefix_and_verifies_against_hash; cargo test admin_password_hash_is_not_a_client_api_key; cargo test --test admin_login_route_test; full fmt/test/clippy before commit	Admin passwords use Argon2id, client API keys use cpr_ prefix plus HMAC-SHA256 with server-side pepper; /admin/login issues HttpOnly sessions and rejects client API keys as admin credentials.
Secret encryption	Completed	105aa58	cargo test secret_box_encrypts_and_decrypts_without_storing_plaintext; full fmt/test/clippy before commit	AES-256-GCM SecretBox stores upstream secrets as v1:<nonce>:<ciphertext> without plaintext.
Logging and pagination	Completed	eb0341e + fc16c48 + b0c10f2	cargo test event_logs_are_cursor_paginated; cargo test admin_logs_are_cursor_paginated_and_include_request_id; cargo test rotating_writer_splits_files_when_size_limit_is_reached; full fmt/test/clippy before commit	Adds cursor pagination, Page<T> camelCase serialization, admin /admin/logs query API, event log repository, runtime tracing initialization, HTTP trace layer, and date/size-based file rotation.
TLS headers and fingerprint	Completed	1bdd08c	cargo test codex_headers_include_desktop_identity_and_turn_state; cargo tree | rg 'reqwest|rustls'; full fmt/test/clippy before commit	Adds Codex Desktop fingerprint model, exact identity/request headers, and pinned reqwest/rustls client builder.
Cookie persistence	Completed	4710926 + 5d3cc6e	cargo test cookie_jar_captures_and_replays_account_scoped_cookies; cargo test cookie_repository_encrypts_and_replays_account_scoped_cookies; full fmt/test/clippy before commit	Adds account-scoped in-memory Cookie jar and encrypted SQLite Cookie repository; Cookies are replayed only for the same account/domain.
Account pool and refresh	Partial	0f97c5c + 2f25db8	cargo test account_pool_skips_expired_disabled_banned_and_quota_exhausted_accounts; cargo test --test account_refresh_test; full fmt/test/clippy before commit	Implemented base account status filtering and refresh scheduler semantics. Still missing original scheduling parity: max concurrent slots, stale slot cleanup, rotation strategies, tier priority, quota-cache filtering, Cloudflare cooldown, request staggering, session affinity, pool integration with the SQLite repository, and admin account CRUD.
Account repository	Completed	14fe706	cargo test --test account_repository_test; cargo fmt --check; cargo clippy --all-targets --all-features --locked -- -D warnings; cargo test	Adds encrypted SQLite account token storage, decrypting reads, cursor pagination, status/label updates, release-time usage counter persistence, and refresh-token-preserving token updates.
Translation	Completed	eff182e	cargo test chat_completion_translates_to_codex_response_request; full fmt/test/clippy before commit	Adds OpenAI Chat request types, Codex Responses request type, translation, and OpenAI-compatible error body helper.
HTTP routes	Partial	ab0ad8f + 3830b21	cargo test v1_requires_client_api_key_not_admin_cookie; cargo test models_route_returns_openai_compatible_codex_model_list; full fmt/test/clippy before commit	Adds Axum router, health route, /v1/models, /v1 unauthorized OpenAI error body, global request-id response header, and binary listener. Still missing admin auth middleware extraction, account/auth/API-key management routes, settings routes, diagnostics, usage stats, model catalog/detail/refresh routes, and additional Responses routes.
Admin/frontend response contract	Completed	1c34ea7 + b0c10f2	cargo test admin_envelope_serializes_lower_camel_case_request_id; cargo test admin_logs_reject_missing_admin_session_cookie; cargo test v1_response_has_request_id_header_without_admin_body_field; full fmt/test/clippy before commit	Adds reusable admin envelopes with body codes, lower camelCase JSON, paginated list shape, requestId bodies, admin session cookie enforcement, and keeps /v1/* OpenAI-compatible.
HTTP auth boundary	Completed	pending	cargo test --test http_auth_test; cargo test --test routes_responses_test; cargo test --test admin_logs_route_test; full fmt/test/clippy before commit	Adds a real src/http/auth.rs boundary for client API key and admin session cookie parsing. /v1/* accepts only Bearer cpr_..., admin session parsing ignores client API keys, and route handlers no longer own ad hoc credential parsing.
Upstream lifecycle	Partial	88cad87 + 225fbff	cargo test responses_route_rejects_non_codex_provider_models; cargo test v1_requires_client_api_key_not_admin_cookie; cargo test --test codex_sse_usage_test; full fmt/test/clippy before commit	/v1 currently enforces client API key shape, rejects non-Codex provider models, returns OpenAI-compatible errors, and includes reusable SSE/usage helpers. It does not yet acquire accounts, forward to Codex, replay/capture Cookies, stream/collect upstream responses, capture rate-limit headers, retry across accounts, record usage, or preserve previous-response/session affinity.
Fingerprint updates	Partial	dd26d31 + e32220a	cargo test update_manifest_updates_app_version_and_build_number; cargo test fingerprint_updater_fetches_manifest_and_persists_history; full fmt/test/clippy before commit	Parses a JSON update manifest and persists app version/build number history to SQLite. Still missing original appcast XML polling, update-state persistence, runtime header fingerprint selection from the latest stored fingerprint, and optional local Codex.app Chromium extraction.
Runtime docs and packaging	Completed	33b63f3	cargo fmt --check; cargo clippy --all-targets --all-features --locked -- -D warnings; cargo test; cargo run; curl -s -i http://127.0.0.1:8080/health	README scope, .env.example, Dockerfile, compose file, and health smoke test are complete.
