+	# Hold The Horde — Exploration Structure
+
+	**Status.** A provisional proposal for review, not owner-approved. It describes how repeated expeditions can form one discoverable, revisitable station. Example fiction is labelled where used. The revival explanation, the station's full history, the escape solution and the languages' design are not settled here and are not needed to settle this. No layout, district count or content programme is proposed.
+
+	## The shape of the campaign: reach, not unlocking
+
+	Oxygen limits how far the astronaut can go and return (owner requirement). That makes reach the natural structure for a campaign of many expeditions: at any moment there is a band of the station the player can work in, and a frontier beyond it.
+
+	The frontier moves outward when the *cost of getting somewhere falls*, not when a gate opens. Three things lower it: carrying capability, so a canister goes further; knowledge, since a known direct route is cheaper than a searched one; and infrastructure the player restores, such as power to a lift. Physical barriers do exist — a sealed door is shut — but they are station state the player can work on with what they understand, not locks waiting on a key found elsewhere. Mostly, places out of reach are out of reach because of supply.
+
+	This has a consequence worth stating plainly: explored space becomes the corridor to unexplored space. The player will cross early areas many times, so those areas must not be inert.
+
+	## What is authored and what varies
+
+	| | Authored and permanent | Varies between expeditions |
+	|---|---|---|
+	| Geometry | Rooms, corridors, junctions | — |
+	| Marks and traces | Cut marks, crew paint, belongings | — |
+	| Machinery | Placement and function | Power state, whether running |
+	| Doors and routes | Where they are | Which are currently passable |
+	| Hordes | — | Population, density, location |
+	| Hazards | Where they can occur | Whether currently active |
+	| Caches (player-created) | Contents and site persist | — |
+
+	The brief lists what a revisit may offer: a changed environment, enemies, understanding, or ability to interact. Layout is not among them, and this proposal does not vary it. Deliberate infrastructure work by the player — power restored, a door unsealed — persists. Consumable state, such as a cleared room, does not.
+
+	## Finding routes and recognising places
+
+	Places are recognised by what is in them: a machine of a particular kind, a wall of marks, a room where someone lived. Recognition is authored, not incidental.
+
+	The station also carries its own addressing. *(Proposed fiction.)* The human crew painted section markings for their own use, in their own hands, so places have readable in-world names the player can write down and say to a survivor. This makes location a thing the player learns rather than a coordinate the game hands over, which is what makes personal note-taking worth doing.
+
+	That fiction has a limit, and the limit is a design dependency rather than a flourish: the crew's names cover only where the crew went. The journal's location reference must therefore rest on a reliable substrate, with the painted names as a legible layer above it. Otherwise references break exactly where exploration becomes most interesting.
+
+	## How earlier observations gain new meaning
+
+	The established pattern is that understanding reinterprets marks the player already walked past. Applied across expeditions, the same evidence keeps addressing a larger object.
+
+	First the marks describe a component. Then a room: a bay whose contacts are all of one family was built to do one job. Then the station: a run of sealed, isolator-marked doors is a boundary someone drew, and its direction says whether they were closing something off or working their way out. The player ends up reading the layout itself with evidence gathered for a different purpose. No new system is required for this, only that the marks stay where they are — which fixed geometry guarantees.
+
+	## Three expeditions
+
+	*Labelled example fiction, using the accepted sortie as its first step. Observed clues, available inferences and resulting choices are kept separate; the inferences are what a player could conclude, not what the game states.*
+
+	**First — the errand.** *Observed:* a rack shutdown runs through one cut-marked part, drains at a second, stops at a third; a pressure door bears an irregular hand-painted copy of one of those shapes; aboard ship, Yeva recognises the paint as Dorn's. *Available inference:* the marks name families rather than parts, and a person deliberately sealed that door. *Choice:* treat the door as a place to return to, or bank the trip and go elsewhere.
+
+	**Second — the sealed section.** *Observed:* the same hand has painted the same shape on several fittings along one route, not on the door alone; behind an open panel, the section's power feed is cut at an isolator-marked contact; the painted marks run *away* from the sealed section rather than into it. *Available inference:* the sealing was deliberate, powered down by hand, and done in sequence — possibly by someone working outward and closing behind himself, possibly by someone shutting something in. Both readings survive the evidence, and the design does not decide between them. *Choice:* restore the feed and open the section, accepting that whatever the isolation was for is no longer isolated; or leave it sealed and follow the painted sequence the other way.
+
+	*Consequence, route:* the same feed powers a hoist on the main run. Restoring it shortens the trip inward for every later expedition — a capability gained by understanding, not by a key.
+
+	**Third — the edge of the crew.** *Observed:* past the hoist, painted section names continue in a different hand, then stop. Beyond them the cut marks carry on across space the crew never labelled. *Available inference:* human presence had a boundary; the station continues past where anyone wrote anything down. *Choice:* press on without the crew's naming to navigate and record by, or work the named band thoroughly first.
+
+	*Consequence, narrative:* the crew's story turns out to have an edge, which is a discovery about people rather than about a mechanism. It resolves nothing about the station's origin, and is not intended to.
+
+	## What a return visit changes
+
+	A revisit is not a repeat because the population and state differ, because infrastructure the player restored is still restored, and above all because the player reads more than they could before. The strongest version costs no new geometry: the room is identical and the player is not.
+
+	## Journal references and cache recovery
+
+	Fixed geometry is what makes both work. A recorded location stays valid indefinitely, so comparing a mark against one seen twenty expeditions ago is reliable. A cache sits where it fell and the route to it continues to exist; whether it can currently be reached, carried and returned within supply is a question of reach, not of whether the room still exists. Those recovery rules are proposed in [Death and Persistence](/Hold%20The%20Flood/Death%20And%20Persistence) and remain under review; nothing here depends on their final form beyond the site persisting.
+
+	## The alternative, and why it might be better
+
+	**Fixed anchors, variable connective tissue.** Authored destinations keep their contents and marks; the corridor and service space between them is regenerated or re-dressed between expeditions.
+
+	Its case is strong and specific. It cuts the largest cost in this proposal — authored content — which is the most credible threat to the brief's scale ambitions. It keeps traversal varied by construction rather than relying on population and state to do that work. And it fits the survivorlike expectation of a different trip each time without needing the station's condition system to carry all the novelty.
+
+	What it costs is priority one. A door the player walked past twice cannot become legible if the corridor may not be there next time, and player-written location references need the game to supply coordinates instead. It would need another way to deliver "changes the meaning of something already seen," and I do not have one that is as cheap.
+
+	**The cost I accept by preferring fixed geometry** is that authored burden, and the real risk that a permanent station becomes a solved commute once its routes are known. Because restored infrastructure persists and shortens known runs, difficulty has to come from depth rather than from re-crossing settled ground. Varying population, hazard and power state is the proposed answer to staleness, and it is unproven.
+
+	## What would change this preference
+
+	Evidence that the authored burden for a permanent station is infeasible at the intended scale, or that varying state and population does not keep re-traversal interesting. Either would make the anchor arrangement the more honest one. No such evidence exists, and written description cannot produce it.
+
+	## Unresolved
+
+	Map generation and how much of the station exists at start; enemy and mechanism reset rules beyond the table above; the journal's positional substrate; how much reach a capability adds; the revival cause, station history, escape solution and language design, all untouched. Nothing here establishes fun, pacing, content feasibility or the 30 / 90 / 100–200 hour ambitions.
