# Oh My Pi 17.2.3: ai& provider, fixes Anthropic OAuth 1M context breakage

> Adds the ai& (`aiand`) provider — an OpenAI-compatible inference API with dynamic model discovery. Fixes a critical bug where Anthropic OAuth (Claude Pro/Max) requests sent the 1M-context beta on every request, breaking all subagents with a hard 429 on subscription credentials. Fixes headless browser launch storms, reasoning blocks leaking into memories, and several coding-agent bugs.

## What changed


- **ai& provider** (`aiand`): OpenAI-compatible API with dynamic model discovery (context windows, capabilities, reasoning, USD pricing), auth via `AIAND_API_KEY`.
- **Critical fix**: Anthropic OAuth requests no longer advertise the 1M-context beta on subscription credentials, which were being rejected with 429. Subscriptions get the standard 200k window. This was breaking all subagents on Claude Sonnet 4.6 and similar models.
- **Headless browser**: Chromium processes now attach to one project-shared daemon-owned browser; concurrent launches share one process; duplicate daemon starts prevented.
- **Memory fix**: reasoning blocks (`thinking…response`) stripped from mnemopi `cleanOutput`, so stored facts no longer contain reasoning prose.
- **Fixes**: OpenAI Codex Responses honor disabled cache retention. Bash auto-background timer no longer delays shutdown. Ephemeral turns preserve prompt cache key. Ask dialog crash on non-string `question` fixed. Codex web search preserves backend error codes. Session-file writing batched for performance.
