🔵 Needs a closer look

Legacy configured seeds bypass timestamp migration and can retain invalid last_seen values indefinitely.

Legacy seeds skip LastSeen backfill and remain inactive

peers/​registry.go:400

Legacy seed records are exempted before the zero-LastSeen migration runs. Because configured seeds are always skipped here, a seed persisted by the previous schema keeps the year-1 timestamp indefinitely and is excluded from ActivePeers whenever disconnected. Backfill LastSeen before applying seed/connection exemptions.

🔵 Needs a closer look

The Go prerequisite and peer-retention exceptions remain inconsistent across the public documentation.

In code that hasn't changed since last review

Document active and pending connection retention exceptions

api/​swagger/​openapi.yaml:264

This omits two retention exceptions implemented by PruneStalePeers: active and pending connections are also retained. The README already describes all three exceptions, so the OpenAPI contract should match it.

Update documented Go prerequisite to 1.27

go.mod:3

The documented build prerequisite is now stale: README.md:388 still says Go 1.23 must be installed, while this directive requires Go 1.27. Update the build documentation so users do not attempt the upgrade with an unsupported toolchain.
