Research direction

Open messaging.md and find the Fragmentation section's list of malformed sequences. Review the referenced handling in noise/wire.py for context, then add the two missing truncated-fragment cases described in the issue. Done means the list explicitly covers missing flags and missing orig_type bytes.

Written by the indexing model from the issue text.

Description

The list of malformed sequences under messaging.md "Fragmentation" is presented as exhaustive, but it doesn't cover a fragment frame that is too short to parse:

  • any fragment with no flags byte (plaintext is just [1])
  • a first fragment with no orig_type byte (plaintext is [1][flags] with bit 1 set)

The receiver can't start reassembly for either one. aiosendspin (noise/wire.py) and sendspin-cpp both already close the connection for these.

Suggested fix: Add "a fragment missing its flags byte, or a first fragment missing its orig_type byte" to the list of malformed sequences.
