Documents the tradeoff between metadata privacy and route error feedback: - Intermediate routers see src_addr/dest_addr (traffic analysis possible) - Source address needed for CoordsRequired/PathBroken error messages - Deliberate choice: explicit feedback over silent drops + app timeouts - Partial mitigation: addresses are SHA-256(npub), not npubs themselves - Notes onion routing as alternative with different tradeoffs
