## What changed


- **pi-agent-core**: Codex V2 remote compaction fixed with explicit v2Endpoint and feature-negotiation header.
- **pi-ai**: `omp usage invalidate` now discards stale OAuth/API-key usage snapshots and forces per-provider refresh; quota reporting fixed for China (Beijing) Alibaba Token Plan credentials.
- **pi-catalog**: wire constants for Codex V2 compaction; GitHub Copilot credentials now scoped per-credential (fixes business model requests hitting personal endpoint with 403); OpenRouter DeepSeek V4 Pro 0813 effort clamping fixed (now accepts low/high/max ladder).
- **pi-coding-agent**: MuPDF-WASM PDF backend replaced with pdf-inspector via pi-natives; PDF page rendering restored via headless Chromium capture; Streamable HTTP MCP sessions no longer invalidated by opening GET SSE stream before notifications/initialized (fixes Figma Dev Mode MCP); Ctrl+D hotkey description corrected; Ctrl+G external editors fixed on Windows (Bun re-quoting).
- **pi-mnemopi**: `recall()` with channel filter no longer drops global-scope rows (buildWhere was appending redundant channel_id clause).
- **pi-natives**: added async pdfToMarkdown API with page numbering, OCR-needed metadata; Docker images build via cargo/napi-rs instead of Bazel; fixed workspace load with stale crate dirs; fixed dockerignore patterns missing nested target/dist dirs; DeviceCheck no longer aborts with SIGTRAP on headless macOS (checks for graphic access first).
- **pi-tui**: terminal DA1 reply leaking into composer fixed (consumed for entire session lifetime, not just probe sentinel).
