DEFAULT_WOVEN_PATH_GRACE

How long a path-lost (ready → waiting) connection is given to recover before the woven seam evicts the peer and tears the connection as CloseReason.Unreachable (#1478) — the public name for the fabric's grace window, so a consumer (or an out-of-tree hardware harness) can read the shipping value rather than mirroring the literal.

The value itself lives on NwSeam, which is internal; this is the one exported alias.
