When the original payload exceeds `segmentSize`, the sender **MUST**:
|
||||
|
||||
- Compute a 32-byte `entire_message_hash = Keccak256(originalPayload)`.
|
||||
- Compute a 32-byte `entire_message_hash = Keccak256(original_payload)`.
|
||||
- Split the payload into one or more **data segments**, each of size up to `segmentSize` bytes.
|
||||
- Optionally generate **parity segments** using Reed–Solomon erasure coding, at a fixed parity rate of 12.5%.
|

Implementations **MUST NOT** produce more than 256 total segments (data + parity).

|
||||
- Reconstruct by:
|
||||
- Concatenating data segments if all are present, or
|
||||
- Applying Reed–Solomon decoding if parity segments are available.
|
||||
- Verify `Keccak256(reconstructedPayload)` matches `entire_message_hash`.
|

- Verify `Keccak256(reconstructed_payload)` matches `entire_message_hash`.

On mismatch, the message **MUST** be discarded and logged as invalid.
|

- Once verified, the reconstructed payload **SHALL** be delivered to the application.
|

- Incomplete reconstructions **SHOULD** be garbage-collected after a timeout.
