The Sable Reach
Description
"Sits on the stable-space lip of the Span mouth… the one fixed chokepoint every hull must pass." Geographically outside the reach, controlling "the single authenticated door into and out of it." "The Cairn does not move; the meaning of what lies beyond it changes" — in Who the Door Admits the edge of an unproven road, by The Cairn the boundary before damaged space.
Classification
Contested strategic chokepoint. The Cairn on it is constituted as a civilian authentication relay (a warship base at the throat "would read as conquest"); Earth's Book 3 militarisation targets it; the Book 3 resolution (the Cairn Compact) makes it multilateral.
Wound state
By The Cairn (planned) the reach beyond the throat has gone wound-riddled; the throat is the boundary before damaged space. The Cairn "watches the sky humanity's own road first visibly damaged".

On the record
- The Dawnward's escape route ("the single door out of the Sable Reach,"); the Span-control infrastructure at the mouth is commissioned into Cairn Relay (the Cairn).
- The reach's gateway; the Book 3 crisis site (trapped mixed transit + emergency bypass both happen here); Adm. Merrick militarises the throat as national survival; "whoever holds it holds the reach." Resolves into the Cairn Compact (Earth losing unilateral authority).
- ~2316+ (The Cairn, planned) The last stable junction before the wound complex; the launch point for the first wound expeditions.
