Critical Files

This page lists files that are critical because source inspection shows they own runtime contracts. It avoids stale claims about parameter counts or training runs. | File | Why it matters | | --- | --- | | `MotionMixApp/Services/EchelonBridge.swift` | Main Swift coordinator. Owns Rust brain/audio handles, SANService, ClaimBridgeService, sensor queues, and dynamics overlays. | | `MotionMixApp/Services/SANService.swift` | Swift wrapper for Rust SAN FFI. Loads `san_weights.bin` and `san_manifest.json`; owns `SANTrajectoryLogger`. | | `MotionMixApp/Services/SANTrajectoryLogger.swift` | Schema-v2 body/SAN capture logger. Writes `Documents/san-training/<session-id>.jsonl`; can push NDJSON to K11. | | `MotionMixApp/Services/DiffusionService.swift` | CoreML/phone-hub/fallback generation service. Uses `ConditioningEncoder` and `FlowGenerator1Step` when available. | | `MotionMixApp/Services/ClaimBridgeService.swift` | Swift wrapper for Rust ClaimBridge. Converts Echelon dynamics into controlled motion inscription claims. | | `MotionMixApp/Services/MocopiFeatureExtractor.swift` | Compresses mocopi skeletons into the app's 24D feature slice and pose stats. | | `MotionMixApp/Services/LiveStreamServer.swift` | Camera-node HTTP surface. | | `MotionMixApp/Services/NodeAdvertiser.swift` | Bonjour camera-node advertisement. | | `MotionMixApp/Services/CameraService.swift` | AVCapture session and capture pipeline. | | `MotionMixApp/Frameworks/libechelon_ios.a` | Rust static library consumed by iOS. | | `MotionMixApp/Resources/san_weights.bin` | Current SAN weight binary. Training provenance must be documented separately. | | `MotionMixApp/Resources/san_manifest.json` | SAN weight manifest. Current local audit: 76 tensors, 164,248 parameters. | | `MotionMixApp/MotionMixApp.swift` | App entry and service wiring. | | File | Why it matters | | --- | --- | | `MotionMixApp/MLModels/ConditioningEncoder.mlpackage` | CoreML encoder used by `DiffusionService`; current Swift shim feeds a 104D input prefix. | | `MotionMixApp/MLModels/FlowGenerator1Step.mlpackage` | CoreML one-step flow/token generator used after the conditioning embedding. | | `MotionMixApp/Models/MotionToMusic.mlpackage` | Separate model artifact; do not confuse it with SAN or the one-step flow lane without checking call sites. | | File | Why it matters | | --- | --- | | `core/audio-media/cc-echelon/crates/cc-brain/src/lib.rs` | Root of the Rust brain crate and public exports. | | `core/audio-media/cc-echelon/crates/cc-brain/src/ffi.rs` | C FFI contract used by Swift. | | `core/audio-media/cc-echelon/crates/cc-brain/src/latent/mod.rs` | `LatentUpdater` trait and backend exports. | | `core/audio-media/cc-echelon/crates/cc-brain/src/latent/simple.rs` | Simple latent updater path. | | `core/audio-media/cc-echelon/
