- Migrated global service tier settings to a per-model-family architecture (OpenAI, Anthropic, Google).
- Implemented `ServiceTierByFamily` mapping to allow independent configuration and resolution per provider.
- Added automatic migration logic for legacy service tier and fast-mode application settings.
- Updated telemetry, session management, and task execution to support provider-specific tier resolution.
- Added test assertions for `preferWebsockets` parity in `advisor-provider-options-parity.test.ts`.
- Introduced a benchmark test to verify propagation of `providerSessionState` and `preferWebsockets` in `bench-auth-fallback.test.ts`.
- Added test suite to validate service tier resolution logic in benchmark commands.
- Verified that command-line flags correctly override application setting values.
- Confirmed default behavior when neither flags nor configuration settings are provided.
- Introduced `withEmptyCompletionRetry` utility to manage bounded retries with exponential backoff for empty streaming responses.
- Integrated completion validation across Anthropic and OpenAI providers to ensure robust handling of intermittent empty outputs.
- Updated `omp bench` and `omp dry-balance` to correctly resolve extension-contributed providers and report content-less runs as failures.
- Added comprehensive unit and regression tests to validate retry logic, provider resolution, and failure reporting metrics.
- Implement JSON repair and strict argument validation to sanitize raw payloads and redact sensitive information from agent event logs.
- Add automatic authentication fallback for benchmark model resolution to ensure consistent performance testing across providers.
- Refactor search tool API parameters by replacing `i` with a case-sensitive `case` boolean flag for clarity.
- Update session history formatting to ensure empty objects are consistently serialized as `{}` instead of empty strings.
