**Builders' runs.** Left by whoever built the structure, above and beside fittings and doorways, as short ordered sequences: `KETH SORAN VEL`. The candidate rule available to the player is positional — that the first token is what the run is about and the rest qualify it. A run is read where it stands.

**The visitors' hand.** A later species wrote on the builders' surfaces in a visibly different hand. It is a language, and the player meets one *register* of it here: marks placed at thresholds in two halves, each carrying a matching bracket token — written as `OSH·a` and `OSH·b` — plus one further token. Pairing is a property of this use, not a claim about the whole language.

- The single-token run is unfinished or damaged.
- The `OSH·a` mark is graffiti, or the same language written badly.

None of these is silly. The first in particular survives a long way, and the article does not pretend otherwise.

## The comparison, and the observation that gives it teeth
+
## The room comparison, stated so it is actually observable
-
The two runs share all three tokens in different order. That alone distinguishes little: two places can perfectly well carry different compound names built from the same elements.
-
-
What makes the comparison worth acting on is a **visible difference in the rooms themselves**, and it needs stating precisely, because "each is about a different thing" is not something a player can see.
+
Two mains run the length of this spine: a pump main and a cable main. Both are visible as continuous runs, and in any given room a main either continues out the far side or comes to an end.
The **test is voluntary and physical**: walk a way and look. It costs oxygen and exposure like any traversal.
-
- The left way ends in a pump hall. Cable trunking crosses it — entering one wall, leaving another, terminating nowhere. The pumps are bolted down, plumbed in and end here.
-
- The middle way ends in a cable junction. The cables terminate: they fan into banked connections that go no further. A pump stands there too, feeding only that room's own cooling loop.
+
- The left way ends in a **pump hall**. The pump main terminates here — the pumps are its end. The cable main crosses the room, entering one wall and leaving another.
+
- The middle way reaches a **cable junction** and continues past it. The cable main terminates here, fanning into banked connections. The pump main crosses and carries on.
+
+
Other things also end in each room — the cable junction has a small cooling pump fed by a branch off the pump main, and it plainly terminates there. That is a local fitting, visibly hung off the main rather than part of its run, and it is why the comparison has to be about the two *mains* rather than about "only one system ends," which is not true of either room.
-
So the observable is *what terminates here and what merely passes through*. In each room both systems are present, and only one of them ends.
+
So the observable is: **of the two mains, which one ends here.** In the pump hall the pump main ends; in the cable junction the cable main ends. The token order tracks that — `KETH` leads over the way where the pump main ends, `SORAN` over the way where the cable main ends.
-
That correlates with the token order. `KETH` leads over the way to the room where pumps terminate; `SORAN` leads over the way where cabling terminates.
+
**What this supports, and what it does not.** It supports the purpose-and-order reading over the stylistic one, because order tracks something the player can see. It does not eliminate compound naming: two places could carry different compound names from the same elements and the correlation would look the same. The player leaves with a working rule, not a proof.

The player leaves with a working rule, not a proof, and that is the honest state of it.
+
`TAAN` over the right way adds a third case — a stair to a vestibule where neither main runs at all. That sits comfortably with a bare subject having nothing to qualify. On its own it settles little; a short name among long ones is unremarkable.

## The visitors' register, and the comparison that gives it direction
-
## The visitors' register, and what a pair actually says
+
A pair marks the two ends of something. What tells the player *which* end is which is not their own route — walking a passage one way says nothing about how the visitors used it.
-
A pair is not only a link. Across pairs the player has completed, the *further* token differs between halves in a consistent way: one recurs at places they entered from, the other at places they moved toward. A completed pair therefore points.
+
It comes instead from an independently observable one-way process. On pairs the player has already recorded, the two ends are the ends of a **transfer** whose direction is visible without reading anything: at one end a driving device pushes into the line, at the other a vessel receives and fills. Across those pairs, one further token recurs at the driving end and the other at the receiving end.
-
That matters because of something the player already did. Earlier, they completed a pair whose halves sat at the two ends of a passage they walked end to end — their own evidence that this species marked the ends of ways they used, and which end was which.
+
That is a small, checkable reading — not a translation. It says the visitors' pairs distinguish a source end from a destination end, and it can be got from two or three pairs whose transfer direction is physically legible. What the tokens *say* remains open.
## Where the second language earns its place
Much later, deep on the far side and reached the long way round, the player finds `OSH·b` beside a bay whose builders' run begins `SORAN`.
-
`OSH·a` at the junction carries the "toward" token; `OSH·b` at the bay carries the "from" token. Under the precedent the player established by walking one themselves, this pair marks a way the visitors used, running from the junction toward that bay.
+
Set against the recorded pairs: `OSH·a` at the junction carries the **driving-end** token, and `OSH·b` at the bay carries the **receiving-end** token. So the visitors marked something running from the junction to that bay.
+
+
There is also an untraversed continuation. The middle way reaches the cable junction, where the player turned back on supply, and a passage carries on past it that has never been followed.
-
There is also an untraversed continuation. The middle way was walked only as far as the cable junction, where the player turned back on supply; a passage runs on past it and has never been followed.
+
**What each language contributes.** The pair says the visitors treated the junction as a source end and the bay as its destination. The builders' runs say the middle way and the far bay are both about cabling, which is consistent with that rather than proof of it. Together they make following the continuation reasoned. Neither is claimed to be indispensable in general, and a player with only the runs has a weaker version of the same idea.

## The choice, and what actually happens if it is wrong
-
## The choice, and the cost of being wrong
+
The player can follow the continuation past the cable junction, expecting to reach the far bay, instead of the long route they have walked before. If it connects, that is expected to be shorter and cheaper in oxygen and exposure — expected, not guaranteed, until they have done it.
-
The player can follow the continuation past the cable junction, expecting to come out at the far bay, instead of the long route they have walked before. If it connects, that is **expected** to be shorter and cheaper in oxygen and exposure — expected, not guaranteed, until they have actually done it.
+
If they arrive somewhere else, the journal records the arrival they actually made against the route link they set. That is a record of where they went, not a verdict on the reading. A blocked or abandoned attempt records as incomplete rather than as a refuted idea.
-
If the reading is wrong they find out by arriving somewhere else, and they see where they are: information rather than a refusal. They have spent the attempt's oxygen and must fall back on the known route, subject to the station's state and their remaining supply.
+
The cost is time, oxygen and interrupted work. Under the owner's rule, carried property comes home regardless, so a detour does not put equipment at risk. What it can cost is the rest of the trip: the player can press on, retreat to the known route, or end the expedition by dying and arrive home with everything. World time and supply still matter, and none of those outcomes is free.
-
A wrong *rule* fails the same way and teaches more: a player who decided the last token is the subject predicts differently, walks, and finds the prediction broken in a specific place with the run still above them.
+
**A wrong rule is not necessarily exposed by one trip.** A player who decided the last token is the subject can make a prediction that happens to hold, or fail for an unrelated reason. What one walk gives is an observation, and observations accumulate.
## Recovering from a wrong guess or a missed clue
Runs and pairs recur, so no single instance is load-bearing. A player who missed `OSH·a` can learn the paired structure from another pair; a player who never completes one still has the builders' runs and the weaker route hypothesis they support.
-
What the design does not claim is that any two swapped runs, or any short run, will do the same work. The rooms in this episode carry a visible terminate-or-pass-through difference; a different pair of rooms might carry nothing comparable. Nor does it claim universal access: a player who never compares occurrences may not reach the positional rule, and the survivor route does not fix that.

**Precisely what that gives.** It does not translate a token. It fixes which *place* each run sits above without the player walking there, so runs can be lined up against known destinations from the record alone. The token-to-purpose mapping, the positional rule, and whether order carries meaning at all remain inferred.

She never read the visitors' hand and says so, so the pair, its direction and the route inference stay with the player. Help shortens the road without walking it, and the unaided player is not treated as the only legitimate one.

## Assistance, and the tradeoff
-
Withholding a correctness badge does not by itself maximise ownership, and explicit help does not by itself remove thinking. The real difference is diagnosis.
+
On request, the journal may surface a previously captured record that looks visually similar to one the player is examining. It is fallible, it is separate from any claim about relation, direction or route, and manual comparison remains fully usable.
-
Bounded confirmation — recording that a stated local prediction *matched here* — costs some ambiguity and risks a status label reading as more authoritative than intended. Withholding it preserves ambiguity, but a sound hypothesis can look wrong because of an unpowered control, a blocked passage, low supply or a death that ended the attempt, and the player cannot tell which. **I accept the first cost**, because in this episode the thing being confirmed is where the player arrived, never what a token means.
+
**What that costs and why I now accept it.** I previously argued for leaving all noticing unaided. What changed my position is that the alternative rests on a prediction I cannot support — that unaided noticing is where the discovery lives — while the burden it creates is concrete: with pairs many expeditions apart, a player can hold both halves and never bring them together. On-request similarity reduces some unaided noticing. It does not interpret, relate or route, and everything above still has to be done by the player.
-
## What remains open
+
**On confirmation.** Recording an actual arrival against a stated route link is not a correctness badge on a hypothesis, and this episode asks for nothing more. Without any record, diagnosis becomes harder rather than impossible: environmental evidence stays visible, and a player can often see why an attempt failed. Calling that "the player cannot tell" overstated it, and I have dropped it.

How records are compared and revised, and whether a completed pair is surfaced as visually similar or left entirely for the player to notice, belong to [Language and Journal](/Hold%20The%20Flood/Language%20and%20Journal). This episode works under either answer, though the second changes how much thinking remains.

## What remains open

Also open: what these tokens mean beyond the placement Yeva's road names allow, who the visitors were, and why they wrote across the builders' walls. Nothing here establishes that inferring a positional rule is enjoyable, or that players will test rather than wait to be told.
