- Refactor deep imports by targeting specific sub-modules in `@oh-my-pi/pi-ai` to reduce barrel file overhead.
- Utilize jitless ArkType scopes in schema definitions to reduce startup JIT codegen costs by approximately 65%.
- Reorganize internal `auth-storage` exports to maintain clean boundaries between core and broker-specific functionality.
- Derived descriptors, default-model map, env keys, login list, and refresh dispatch from one ProviderDefinition per provider.
- Disabled OpenAI Codex stream obfuscation and interrupted whitespace-only tool-call argument deltas.
- Derived auth-broker callback ports and paste-code login set from the registry.
- Updated the auth-broker CLI to import the transport setter from the logger module.
- Replaced the logger.setTransports call in runServe with the dedicated setTransports helper.
- Migrated OAuth provider authentication from standalone `pi-ai` CLI to in-process `AuthStorage.login()` flow in coding-agent.
- Made provider argument optional for `login` and `logout` commands with interactive provider picker when omitted.
- Added `list` command to enumerate registered OAuth providers with optional `--json` output format.
- Removed `pi-ai` CLI binary and `bin` entry from @oh-my-pi/ai package; library API remains unchanged.
- Updated documentation and examples to reflect new `omp auth-broker` command interface and in-process OAuth flow.
- Added generation-aware snapshot contracts with generation, serverNowMs, refresher, and rotatesInMs fields.
- Reworked /v1/snapshot serving and client fetching for If-None-Match long-poll with 304/200 status handling.
- Added status checks in remote-store and SDK/CLI snapshot paths, applying updates only when fetch returns 200.
- Added StreamOptions.onAuthError and stream one-shot 401 retry dispatch using refreshed credentials.
- Added a new `setTransports` logger API to swap console and file winston transports at runtime.
- Refactored logger transport creation to lazily build rotating file logs via a shared directory helper.
- Updated auth-broker serve startup/shutdown to use structured logger output and switch to console-only logs for its headless runtime.
- Added `omp auth-gateway serve/token/status` — a forward-proxy injecting broker credentials for OpenAI Chat, Anthropic Messages, and OpenAI Responses wire formats.
- Added `GET /v1/usage` to auth-broker and auth-gateway; usage cache switched to 5-min per-credential TTL with jitter and last-good fallback on failure.
- Added `AuthStorage.setConfigApiKey/removeConfigApiKey/clearConfigApiKeys` so `models.yml` `apiKey` beats OAuth tokens without overriding `--api-key`.
- Added `omp auth-broker migrate --from-local` for idempotent upload of local SQLite/env credentials to the broker.
- Added `AuthBrokerClient`, `RemoteAuthCredentialStore`, `AuthBrokerRefresher`, and `startAuthBroker` server in `packages/ai/src/auth-broker`.
- Renamed `AuthCredentialStore` class to `SqliteAuthCredentialStore`; extracted `AuthCredentialStore` as a persistence interface.
- Added `exportSnapshot`, `forceRefreshCredentialById`, `disableCredentialById`, and `upsertCredential` to `AuthStorage` for broker wire protocol.
- Added `omp auth-broker` CLI subcommand (serve, token, login, logout, import, status) and `discoverAuthStorage` broker-mode path keyed on `OMP_AUTH_BROKER_URL`.
