# Oh My Pi 17.2.6: /reset command, Bedrock Mantle provider, file locks

> Adds a `/reset` command that clears conversation context in-place while preserving session identity, transcript, and model. Introduces the Bedrock Mantle provider with authenticated discovery for OpenAI GPT-5.x models through Amazon Bedrock's Responses endpoint. Adds opt-in SQLite page-size configuration for mnemopi and process-owned file lock utilities. Fixes peer-IRC interrupt handling, Ollama without user-role messages, and several session/branching bugs.

## What changed


- **`/reset` slash command**: drops live messages, queued turns, pending tool calls, and async jobs while keeping session id, title, cwd, model, and on-disk transcript. Pre-reset history stays on disk.
- **Bedrock Mantle provider** (`bedrock-mantle`): authenticated model discovery for OpenAI GPT-5.4, GPT-5.5, GPT-5.6 (Luna, Terra variants) via Amazon Bedrock Responses endpoint.
- **mnemopi**: opt-in SQLite page-size via `MNEMOPI_DB_PAGE_SIZE` env var or `pageSize` option.
- **FileLock bindings**: Unix abstract sockets, Windows named mutexes, `flock(2)` sidecars; shared `file-lock` utility with auto-release.
- **Fixes**: peer-IRC interrupts no longer skip non-interruptible tool calls; interrupt messaging distinguishes parent steering from advisory. Ollama requests without user-role message now generate output. Extension slash commands no longer appear as user prompts. Session titles preserved when branching. Browser guest JS rejections caught as tool errors, not crashes. Windows PID-recycling fix for cancelled bash timeout. macOS PCRE2 JIT disabled by default. `/btw` branch promotion fixes. Database bloat fixed via archived session stats cleanup. Startup hang on local model discovery timeout fixed.
