## [0.1.0] - 2025-12-03

### Added

- High-fidelity AWS Lambda Runtime API (`/2018-06-01/runtime/`)
  - `GET /invocation/next` with long-polling
  - `POST /invocation/{id}/response`
  - `POST /invocation/{id}/error`
  - `POST /init/error`
- Extensions API (`/2020-01-01/extension/`)
  - `POST /register` with identifier generation
  - `GET /event/next` for INVOKE and SHUTDOWN events
  - `POST /exit/{reason}` for graceful shutdown
- Telemetry API (`/2022-07-01/telemetry`)
  - Platform event subscription (platform, function, extension)
  - Buffering with configurable `max_items`, `max_bytes`, `timeout_ms`
  - All platform events: `runtimeDone`, `initStart`, `initRuntimeDone`, etc.
- Process freezing simulation
  - `FreezeMode::Process` using SIGSTOP/SIGCONT (Unix)
  - `FreezeMode::Notify` for cross-platform testing
  - Epoch-based race condition prevention
- Event-driven test helpers
  - `wait_for_runtime_ready()`
  - `wait_for_invocation_complete()`
  - `wait_for_extensions_ready()`

- Environment configuration via `EnvConfig`

### Known Limitations

- Timeout enforcement not yet implemented (deadline calculated but not enforced)
- Environment variables not automatically injected
- Extension registration allowed after init phase
