## Accumulated Context

### Decisions

Decisions are logged in PROJECT.md Key Decisions table.
Recent decisions affecting current work:

- [v1.1 Research]: API choice unresolved — test DwmGetDxSharedSurface first (no border), fall back to WGC if GDI apps fail
- [v1.1 Research]: Use prebuild (not prebuildify) for cmake-js compatibility
- [v1.1 Research]: PNG encoding in C++ via stb_image_write to avoid 8MB raw buffer transfers

### Pending Todos

None yet.

### Blockers/Concerns

- API choice must be resolved empirically in Phase 5 before committing to implementation
- Native addon crash kills MCP server — defensive RAII coding mandatory
- DwmGetDxSharedSurface undocumented — could break on future Windows updates
