Eliminate the errorCode property from server logger calls, error contract types, and API error bodies throughout the codebase. This reduces duplication and streamlines error reporting, relying on structured event names and error classes for identification. All affected API routes, server logic, and logging utilities have been updated for consistency. Documentation directory added for future reference.
Introduce `serverLogger` utility based on pino for consistent, structured logging across all server and API modules. Replace direct console logging with `serverLogger` and add request-scoped logging helpers. Update environment variable handling, documentation, and deployment guides to reflect new logging configuration (`LOG_FORMAT`, `LOG_LEVEL`, `COMPUTE_LOG_LEVEL`). Enforce no-console in server code via ESLint and add pino/pino-pretty dependencies.
This change standardizes log output, improves observability, and prepares the codebase for ingestion by log platforms.
Transition all TTS-related logic, types, and UI to use the new providerRef/providerType model in place of legacy ttsProvider fields. Introduce a centralized tts-provider-policy module to encapsulate provider/model capability checks, default value resolution, and compatibility logic. Update all API routes, contexts, hooks, components, and tests to use providerRef and providerType, ensuring consistent handling of built-in and shared TTS providers. Remove legacy defaultTtsModel config in favor of per-provider defaults and shared provider admin control. Add the showAllProviderModels runtime flag to restrict users to provider default models when desired.
BREAKING CHANGE: ttsProvider fields are replaced by providerRef/providerType throughout the codebase; defaultTtsModel config is removed in favor of per-provider defaults.
Move resolveVoices and resolveReplicateVoiceInputKey to a new server-side
voice-resolution module to improve separation of concerns and reduce shared
bundle size. Update all imports and related tests to use the new module.
Remove unused LRUMap and related caches from shared catalog. Update Replicate
cooldown logic to use per-scope LRU cache for improved concurrency handling.
