# Pi v0.83.0: credential export, headless OpenRouter login, Claude Opus 5, TypeBox breaking changes

> Pi v0.83.0 adds credential export commands for external clients, headless OpenRouter sign-in over SSH, and Claude Opus 5 support via GitHub Copilot. The bundled TypeBox aliases were upgraded to 1.3.7 with several removed APIs, a breaking change for extensions using deprecated features. Dozens of fixes include session streaming, context file loading, Git package installs, and llama.cpp token accounting.

## What changed


- `pi auth print-api-key` and `pi auth print-bearer-token` export configured credentials with automatic OAuth refresh and minimum-validity enforcement
- Headless OpenRouter login: paste redirect URL or auth code when loopback callback is unavailable
- Claude Opus 5 on GitHub Copilot with adaptive thinking and 1M context window
- **Breaking:** TypeBox aliases upgraded to 1.3.7, removing `Type.Base`, `Type.Awaited`, `Type.Promise`, `Type.AsyncIterator`, `Type.Iterator`, `Type.Options`, `Value.Mutate` — extensions using removed APIs must migrate
- `ctx.scopedModels` exposed to extensions
- Inherited per-request `fetch` injection for text/image provider transports
- `"pending"` stop reason for partial streaming messages
- Raw provider stop reasons across Google, Anthropic, Bedrock, Mistral, OpenAI streams; unmapped terminal reasons now surface as provider errors
- OAuth token refresh triggers at 5 minutes remaining instead of expiration
- Fixed: file-backed SYSTEM.md/APPEND_SYSTEM.md omitted from startup context listing
- Fixed: context files loading twice under nested Git worktrees
- Fixed: llama.cpp streamed responses reporting zero token usage
- Fixed: session replacement during active response now persists outgoing turn
- Fixed: failed Git package installs leaving partial directories
- Fixed: /model selector retaining stale selection while filtering
- Fixed: direct RPC bash commands bypassing extension user_bash handlers
