# SAD Component → Source File Mapping

**Purpose:** Developer convenience mapping from ASPICE architecture components to source file locations. This is NOT an ASPICE document — it's a lookup for developers.

## Component Mapping

| SAD Component | Source Location |
|---|---|
| Flutter app shell | `apps/chanora_flutter/lib/main.dart`, services, widgets |
| Flutter service layer | `apps/chanora_flutter/lib/services/` |
| Flutter widget layer | `apps/chanora_flutter/lib/widgets/` |
| Bridge layer | `crates/chanora_bridge/src/api.rs`, `apps/chanora_flutter/lib/src/rust/` |
| Rust core | `core/chanora_core/src/lib.rs`, `events.rs`, `network_diagnostics.rs`, `ptt.rs` |
| Protocol adapter | `crates/chanora_protocol/src/` |
| State sync | `crates/chanora_state/src/lib.rs`, `channel_join.rs` |
| Audio subsystem | `crates/chanora_audio/src/` |
| Storage | `crates/chanora_storage/src/lib.rs` |
| Diagnostics | `crates/chanora_diagnostics/src/lib.rs` |
| Resolution and prefetch | `crates/chanora_resolver/src/lib.rs`, `crates/chanora_prefetch/src/lib.rs`, `prefetch_debouncer.dart` |
| Build and release hooks | `.github/workflows/`, `tools/`, platform project files |
