Field truth comes first

Current geometry,
without the overclaim.

The final R08AM snapshot passes 19 of 22 representative normal-walk routes. The C01 mountain portal-to-L1, MainStreet warehouse drive-hall, and Observatory hidden portal-gallery connections are unproven and are not advertised as routes. ISSUE-002 remains open. No world edits were made for this report.

Current access audit

Public, staff, restricted, sealed.

Empty Eight's eleven vacant south bays and two PF08 stairs are public internal circulation. BOH is staff/service only. The grand stair and lower theatre/private-club annex are adults-only, restricted, and non-public. Exterior egress and every future-system interface remain closed.

public

11 bays · 2 stairs

S01–S05 and S07–S12 are publicly viewable vacant shells. S06 stays capped.

Skywalk logic, underground

Read connections
at a glance.

Inspired by downtown skywalk diagrams: each box is a separate underground system, nodes are useful destinations, and lines are verified internal connections. No line between systems means no verified connecting tunnel.

Area-by-area navigation

Ten local maps.

Geographic plans preserve world coordinates, access markers, and local route geometry. Open any map for its full-resolution version.

Cataloged C01 room graph

Seven levels.
One vertical stack.

168 spaces and 181 route edges are indexed across security, garage, living, hospitality, agriculture, utility, command, owner-club, and residential programs. The maps document interior logic without claiming the contested surface arrival is complete.

The ways in

Every cataloged entrance.

Exact points are used where the catalog proves them. Centroids and contested surface nodes say so plainly—read those against in-world doors, signs, and terrain.
