**What this is.** One representative sortie from the ship into the station and back, written to show that a clear immediate goal, ordinary horde pressure, a discovery that changes understanding and a purposeful return can be one trip rather than four activities. It is a comparison scenario, not an opening mission and not settled design. Requirements come from the [Owner Brief](/Hold%20The%20Flood/Brief); everything else is a proposal, and revival and the ending stay open. Build rules: [Build Comparison](/Hold%20The%20Flood/Build%20Comparison). Scope: [Design Plan](/Hold%20The%20Flood/Design%20Plan).

**The trip in one sentence.** Bring back an intact compressor head — and come home able to read marks you had already walked past twice.

## Leaving the ship
-
The colony wants the compressor head: station gear that packs a canister denser than the ship can alone. The ship makes unlimited oxygen (owner requirement); what it cannot make is *reach*. That is why a successful trip pays out in exploration rather than damage.

Yeva Kolb — a station pressure-tech the player rescued on an earlier trip — names the workshop and one condition: the head has to arrive uncracked. That is the entire immediate goal, and it is checkable at any moment.

## The rack
-
The head sits in a powered rack whose state is legible: it holds until unpowered, and unpowering it is a deliberate act with a visible consequence in the room. Retrieval is a commitment, not a pickup — freeing the head takes a moment the player has to protect, and afterwards they are carrying it, living with the space decision made back at the ship. Finding and identifying the head does not complete the objective. Only arriving with it does.

## What the player notices
+
The shutdown is also the first thing the player watches a mark do. It travels visibly through the rack, runs through one cut-marked part and stops dead at another marked differently. Nothing is named. The player has simply seen two marks behave differently, once. *This depends on a rule Systems owns and has not yet confirmed — see Dependencies.*
-
The service bay behind the workshop is where the errand stops being an errand. Cut marks recur here across components that plainly do different jobs, yet each mark stays consistent within its group. A player who compares them can conclude, unprompted, that the marks name *families* — relay, sink, isolator — rather than individual parts.

## What the player notices

Three things matter about how that is presented.
+
The service bay behind the workshop finishes the job the rack started. There the player watched two marks behave differently, once. Here the same shapes recur across components that plainly do different jobs, each staying consistent within its group. One observation becomes a pattern, and a player who compares them can conclude, unprompted, that the marks name *families* — relay, sink, isolator — rather than individual parts. Evidence first, generalisation second, and the inference is never handed over.
-
- **Observed, not unlocked.** Nothing is revealed here. Every mark was physically visible the first time the player walked past it; the bay is only where enough of them sit close enough to compare. No solve button, no survivor who translates. The notebook preserves a facsimile and location of a mark the player chooses to record and does no more — no naming, no highlighted match, no translation. The inference stays the player's, and knowing three families is not knowing a language.

-
- **Paid for in oxygen.** Standing in that bay is time, and time is supply. This does not dissolve the brief's tension between pressure and curiosity — it makes the payment worth making.

## The way out
The return trip is the point of the whole design. The corridor is the same corridor. The player is not.
-
They fight differently now, because of what they are holding. In hand, the head leaves only basic defence: the build the player spent capacity on is unusable while it is in their arms. Stowing it on the carry frame gives the build back, but the transfer is deliberate and exposed and the head still occupies its full space. Dropping it restores handling and frees that space at once — and leaves a fragile objective on the floor behind them. Enemies that were a nuisance inbound are a decision outbound.

In hand the head leaves only basic defence: the build they spent capacity on is unusable while they are holding it. Stowing it returns the build through a deliberate, exposed transfer, and it still occupies full space. In-hand carriage is brief by design — once stowing is safe the player takes it, and no threat is invented to keep them holding it. The honest recurring decision homeward is stowed against dropped, and dropping frees space and handling at once while leaving a fragile objective on the floor behind them.
-
And the marks they walked past have stopped being scenery. The cut mark on the crate is a sink, and the component will behave like one.
+
The marks they walked past have also stopped being scenery. The crate's cut mark reads as a sink now, making it the trip's last capacity question: make room, or leave it knowing what they are leaving.
-
The door is the discovery's second half, and it reads differently. The paint is irregular where the cutting was exact: it is a copy, made by a human hand from a shape the crew did not understand, used as a label of their own. It identifies nothing mechanical and does not pretend to. What it says is that someone deliberately cut that section off, and wanted other people to know.

The door reads differently again. Its paint is irregular where the cutting was exact — a copy, made by a human hand from a shape the crew did not understand and used as a label of their own.

## Home
-
The return is purposeful three times over. The head is installed and the colony's canisters reach further. The knowledge outlives the trip. And Yeva recognises the paint: it is Dorn's, her work partner, whom she has not named before now.

That is the proposed channel, and it earns its keep: showing a facsimile to a survivor is what the notebook is *for*, and it is the reason to record an irregular scrawl that means nothing at the time. Survivors read handwriting, not language. The consequence is therefore missable rather than automatic — a deliberate cost, since a player who recorded nothing gets no scene — but missable is not lost: the mark stays on the door and Yeva reacts whenever she is shown it.
-
That is the human consequence, and deliberately not a resolution. She does not know whether he sealed the section to keep something out or to keep himself in; neither does the player, and she wants to know. Her value here is human context — whose hand, which crew practice, what the labels meant to the people who made them — while the pattern-finding stayed with the player. She is a person, not an upgrade dispenser.

Shown it, she says it is Dorn's — her work partner, whom she has not named before now. That is the human consequence, and deliberately not a resolution.

## What the player can now do differently
-
- **A named place to go back to.** The sealed door is a later objective the player chose, not a quest handed out.
-
- **A reusable reading.** Family marks recur across the station, so the discovery changes which components are worth carry space on every later trip. How that feeds build choices belongs to [Build Comparison](/Hold%20The%20Flood/Build%20Comparison).
-
- **A second reading of the same script.** A cut mark names what a component does; once the family is learned it reliably predicts whether that component transfers, absorbs or interrupts an effect. A painted copy of the same shape records what the crew was doing — which sections they cut off, what they thought worth labelling. Two kinds of information in one script, told apart by how the mark was made. Neither lies to the player.
+
- **A named place to go back to.** The sealed door is an objective the player chose, not one handed out.
+
- **A reading that travels.** Cut marks recur station-wide, so the families change which components are worth carry space later; painted copies of the same shapes carry crew context and no mechanical claim. Two kinds of information in one script, told apart by how the mark was made. What the families feed into is [Build Comparison](/Hold%20The%20Flood/Build%20Comparison)'s to state, and it rests on the rack observation below.
- **More reach.** The installed head reopens places the player had to turn back from.
## Provisional mechanics and dependencies
None of this is owner canon. The scene survives if these change.
-
- **Shared carry interface.** Equipment versus salvage is an owner requirement; canisters competing for the same space is a working assumption shared with Systems for this comparison. If oxygen gets separate capacity the loadout decision weakens, but the scene holds.
-
- **Carry states.** In hand, stowed and dropped are the interface reconciled with [Build Comparison](/Hold%20The%20Flood/Build%20Comparison); no magnitude is asserted on either side, and the states are visible rather than hidden penalties. That the head changes how the player fights is what gives the return leg its meaning.
-
- **Findability across trips.** The sealed door must remain locatable later, or the human consequence leads nowhere. That requires *discovered locations to persist* — weaker than a fixed station map. Map and persistence structure stay open.
-
- **Death losses.** Undecided. What happens to a carried head on death changes the whole risk calculation of the return leg, and is deliberately not settled here.
-
- **Notebook.** Facsimile and location of marks the player chooses to record, and nothing else — no naming, matching or translation. Reconciled with Systems and provisional on both sides.
-
- **Salvage magnitude.** How much reach the head adds, and whether it is unique or one of a class, are open and not mine to set.
+
- **The rack observation.** That unpowering visibly runs through one marked part and stops at another is proposed here and not yet confirmed by Systems. It is the only *observed* evidence the family inference rests on. If Systems declines it, the honest correction is to keep the discovery as understanding plus the chosen door and drop the mechanical reading — not to assert a behaviour the player never sees.
+
- **Carry rules.** In hand, stowed and dropped come from [Build Comparison](/Hold%20The%20Flood/Build%20Comparison); no magnitude is asserted. Two points are Systems' and this scene follows whatever they set: whether the head occupies capacity while held, which decides whether the loadout paragraph's "going in heavy" cost is real, and confirmation that in-hand carriage is meant to be transient.
+
- **Shared carry interface.** Equipment versus salvage is an owner requirement; canisters competing for the same space is a working assumption. If oxygen gets separate capacity the loadout decision weakens but the scene holds.
+
- **Notebook.** Facsimiles and locations of marks the player records, and nothing else. Showing one to a survivor is the proposed use that makes recording worth doing.
+
- **Findability across trips.** The sealed door must stay locatable later or the human consequence leads nowhere. That needs *discovered locations to persist* — weaker than a fixed map, which stays open.

- **Salvage magnitude.** How much reach the head adds, and whether it is unique or one of a class, are not mine to set.
## What this does not establish
-
That this is fun; that oxygen pressure tunes to a level rewarding care rather than punishing it; or that horde combat and unhurried observation sit well together in the same minute of play. Those are the real risks and a written scene cannot settle them. One narrower claim holds: this discovery reuses signage and corridors that already exist, so its cost is authored *meaning* rather than new geometry — a reason to prefer this kind of discovery, not evidence about the 30 / 90 / 100–200 hour ambitions, which remain unvalidated.
