- Add uploadBlob (@21) and downloadBlob (@22) RPCs to Cap'n Proto schema with SHA-256 content addressing and chunked transfer - Server blob handler: 256KB chunks, SHA-256 verification on finalize, .meta JSON sidecar, 50MB size limit, content-addressable storage - Add FileRef (0x08) AppMessage variant with blob_id, filename, file_size, mime_type - /send-file command: read file, compute hash, upload in chunks with progress display, send FileRef via MLS, MIME auto-detection - /download command: fetch blob in chunks with progress, verify hash, save to disk with collision avoidance - 2 new E2E tests: upload/download round-trip with partial reads, hash mismatch rejection (14 E2E tests total) - New error codes: E024-E027 for blob operations

//! Structured error codes for server RPC responses.

//! Every `capnp::Error::failed()` message is prefixed with a stable code

//! (E001–E020) so clients can match on the code without parsing free-text.
