The Real Story Of P1: Deliver_incoming() Skips

The Hidden Loophole in InnerEnvelope Design

  • Plaintext skips signature check
  • Forgers exploit MLS ambiguity
  • No validation of sender authority

Core Failure: No Signature Enforcement

  • Packender > theory; practice undermines Ed25519
  • Verify_inner_signature sits unused
  • Message issuer wins the game

People Act on Forgery

  • Medical, legal, civic trust collapses
  • A single invalid signature wipes trust
  • Example: Board meeting vote altered overnight

Weighty Takeaway

  • Let’s make signature verification mandatory, not optional
  • Stop releasing plaintext to buffer
  • Enforce re-sign-up before routing

Is Your System Still Vulnerable?

  • Even audit logs miss this gap
  • Train teams: look beyond MLS
  • Focus on End-to-End authentication

The truth? Forged messages pass normal decryption, then cheat the signature. That's how lost trust spreads. Here is the deal: this isn’t just code - it’s a social contract.

The Bottom Line

Delivering without verification isn’t security. It’s invitation to fraud. This isn’t an error - it’s a threat. Without fixing now, you’re playing catch-up.

Every chain of trust starts with signed bytes. The core truth is clear: Verify. And enforce. That’s how we keep it honest.

This topic touches on message attribution and secure messaging. We need solutions that honor both protocol and practice.
