/* PURPOSE */
Retrochannel 2100 is a public logging and review protocol for claimed future-to-present signals.
It records claims and control questions for later review. It does not claim to prove time communication.

/* INTEGRITY MODEL */
Active chain: Chain v2
Chain v2 status: active tamper-evident public hash chain from a new genesis checkpoint
Legacy chain: Chain v1 preserved as a closed archive after an integrity break during deployment/rollback work
Legacy policy: preserved for transparency, not treated as the active public trust chain
