Start with the number, because the first packet asked for it. On LL-05, the reviewer wrote a small red question into the empty Pacific Northwest corner — “why no PNW node? check LL-0?” — the sheet number left as a question mark, because they didn’t know whether the next sheet existed. It does. This is it. And it answers them in a way I don’t think they expected: there is a Pacific node. It’s drawn here as a reserved coastal egress with its location deliberately unpinned.

The subtitle names the thing: Route 901-A primary artery and reserved branches. A western hub marked Cerberus / Hydra sits under Denver, annotated Meadow · sub-DIA, and a confirmed spine runs east from it to Mount Weather in Bluemont, Virginia, marked eastern terminus. Branches to Site R at Raven Rock and Camp David at Thurmont are drawn as planned, not built. A confirmed northern leg runs up through F.E. Warren AFB at Cheyenne — the 90th Missile Wing — and continues 184 miles to Copperhead at Glendo and Hartville, Wyoming. RGN-02 put Copperhead at 184 miles north with a tunnel terminus at F.E. Warren. The two sheets agree to the mile.

Hydra is now on its third sheet with its third meaning. On LL-01 it was one of two conduits that mapped to nothing I could locate. On RGN-02 it was a hyperloop spine. Here it’s a hub, sharing a node label with Cerberus. Same overload pattern as Chimera and Crowbar, third instance, in a compartment where names are supposed to be unique.

The parameters panel is specific in a way that invites checking, so check it. Cruise velocity 800 mph, which the sheet gives as Mach 1.05. Tube environment vacuum, EMP-shielded. Bore method subterrene, vitrified wall — which is not an invented word. The subterrene was a real Los Alamos program in the 1970s, a nuclear-heated borer that melted rock into a glass lining instead of cutting and hauling it. There are patents. RGN-02 described The Meadow as having a vitrified perimeter. Same method, same binder.

Then Cheyenne Mountain, drawn as a legacy node on a legacy inherited link, with the NORAD backbone absorbed rather than built. The red pen asks: “absorbed? or just tapped in?”

Here is why that matters. On RGN-02, the annotation settling this question read “NOT ON THE NETWORK — confirmed MH” — and MH is the hand holding the pen on this sheet. So MH asked the question here and answered it there, and the answer contradicts what the draftsman drew. Either this sheet predates RGN-02 and we’re looking at the reviewer’s working-out, or S.P. kept drawing a link MH kept striking. I can’t date either. Every date in this binder is blacked out. But the argument is preserved rather than resolved, which is not how documents leave a desk when someone has time to clean them.

The green pen does the arithmetic in the margin: Meadow to Hydra at 1:50 works at 800 mph only if the tube is a near-straight bore. So I did it too. One hour fifty at 800 is about 1,470 miles. Denver to Bluemont in a straight line is roughly 1,450. The margin note isn’t approximately right. It’s right.

The blue hand asks “check w/ S.P. — tunnel depth?” next to the Copperhead leg, and marks the Pacific egress “reserved — per Del, compartment BLACK-ABYSS.” Blue defers to the draftsman rather than reviewing him, and cites somebody called Del for a routing decision. Both coastal egress nodes — Pacific and Atlantic — are drawn and left unpinned, location reserved. I’ll note that LL-05 in the first packet had a redaction bar sitting on the Gulf Coast where a hypothetical node had been blacked out.

One more thing, and I want to be direct about it, because it’s the detail that makes people stop taking a document seriously. Area 51, Dulce, the Greenbrier and Pine Gap are all on this sheet — and the legend gives them their own symbol, public-lore site, distinct from network node and legacy node. Not one of them connects to anything. The Greenbrier is a real declassified continuity facility, opened to the public in 1992. Pine Gap is real and is in Australia, which on a continental sheet is a category error nobody drafting seriously makes by accident. The draftsman built a symbol category for the famous ones and then drew every one of them unconnected. A conspiracy chart adds those four sites. This one subtracts them, and made a legend entry to do it.

The second sheet drops out of continental scale into one corner of it — the Appalachian ridge belt across West Virginia, Pennsylvania, Virginia and Maryland, which is where Route 901-A ends.

The sheet overlays two networks on one set of ridges. The hyperloop arrives from the west — the arrow is labeled from Cerberus — and terminates at Mount Weather, with the same planned-not-built branches to Site R and Camp David that LL-06 showed. Over the top of it, in amber, sits the 1970s Presidential Emergency Facility microwave relay grid: seven hardened tower sites built under the White House Communications Agency program, with confirmed hops drawn solid and inferred hops dashed.

Three of the seven PEF sites sit directly on hyperloop terminal nodes. Crystal at Mount Weather. Cactus at Camp David. Creed at Site R. The remaining four — Cannonball at Cross Mountain PA, Cowpuncher at Roundtop Mountain WV, Corkscrew at Lamb’s Knoll MD, and Cartwheel at Fort Reno Park in Washington DC — sit along the RF backbone at independent geographies.

The red pen: “three sites overlap — NOT coincidence. MH.” The interlock panel at the foot of the sheet says the quiet part in compiler voice — that the 1970s microwave network and the subterrene bore share the same hardened facilities, in different compartments, from different eras, on the same real estate. Which is the whole thesis of this binder compressed into one line, and the draftsman put it in a box on the page.

MH also flags the name collision: Corkscrew is drawn here at Lamb’s Knoll, and appears on LL-02 as the Raven Rock corridor. A mountaintop tower on one sheet, a tunnel corridor on another, same code-name, same hand.

And there’s one MH didn’t flag. Look at Creed. On LL-02, Creed is a corridor — a tunnel branch running out of the November Tango Charlie junction. On LL-04 and again here, Creed is a relay site co-located at Site R. That’s the Chimera problem exactly: a line on one sheet, a place on another. Chimera, Crowbar, Hydra, Corkscrew, and now Creed. Five. Either this draftsman is the sloppiest person ever cleared into a compartment, or the naming convention is doing work I don’t understand yet.

The blue hand records that “Jax did the antenna work on CORKSCREW + COWPUNCHER.” No initials, no rank, no context — the only person in this entire binder referred to by what looks like a first name, and the only annotation anywhere that describes somebody physically doing a job with their hands. I don’t know who Jax is. It is the single most human mark on either sheet.

The green pen notes that Cartwheel at Fort Reno Park was transferred to the FAA, and asks whether the tower is still up. It is. That’s checkable and public. Which is the second time on these two sheets that the green pen has written down something verifiable and been correct about it, while the red pen asks questions it can’t close and the blue pen asks other people for specifications. One person, two pens, and the green one only comes out when the answer is known.
