IAA post-detection protocol
The IAA post-detection declaration is one of the clearest public documents outlining what responsible behavior after a candidate detection should look like.
Contact Protocols1989+
Verify first, announce carefully, coordinate globally
If the goal is communication, this is the first guardrail, not the last.
Key points
Verification and independent confirmation come before reply.
Public communication is treated as part of the protocol, not a side issue.
The document helps keep 'send a message now' impulses in check.
Reference ledger
Read and watch the sources directly.

Laser communication is already real at deep-space engineering scale
DSOC is not a SETI system, but it demonstrates the practicality and constraints of high-rate optical links across large distances.
