CHRONOGRID P2P - AI CONTEXT & ARCHITECTURAL MANDATES

1. DATA SOVEREIGNTY & LOCAL-FIRST MANDATE:

   • Never generate code that transmits data to third-party cloud endpoints or SaaS providers.
   • All network synchronization MUST utilize crates/chronogrid_net over libp2p / QUIC with Noise XK encryption.

2. TECH STACK BOUNDARIES:

   • Presentation: Flutter (Win32 for Windows, GTK3 for Linux, Android NDK).
   • Core Logic & Storage: Rust (crates/chronogrid_core) with SQLCipher & Automerge CRDT.
   • FFI Bridge: Use flutter_rust_bridge C-ABI generation ONLY.

3. SINGLE SOURCE OF TRUTH:

   • Prior to modifying data structures, consult docs/API_CONTRACTS/schema.sql and docs/ARCHITECTURE/01-OSAD-system-architecture.md.
   • Update documentation in /docs concurrently with code changes.
