	The astronaut stops at a threshold with a reason to be there: a part sitting in a cradle, a record on a wall, a machine that has to be opened, a door that leads further in. Before stepping through, they can read the room. They see the thing they came for, the hatch, grille or ward door the crowd will come through, the pillar or rail that breaks a firing line, the control that shuts the opening, and the way back out. Nothing comes from nowhere. If bodies arrive, they arrive through an opening the player could have looked at first.
-	That look is where anticipation lives. A closed hatch with dust sifting through its grating promises what is about to happen. The build answers it. A rig that eats dense lines wants the lane where the crowd funnels. A rig built to shove wants the plate or rail the crowd can be pushed onto. A rig back at its starting strength wants the pillar, the long way round and the closure within reach. The crowd is the spectacle: a stream down a narrow bay, a river through a junction, dozens off a gantry stair, hundreds across a great gallery. The fight is about holding space while the astronaut's hands are busy with work.

The crowd is the spectacle: a stream down a narrow bay, a river through a junction, dozens off a gantry stair, hundreds across a great gallery. Mostly the astronaut is on the move, cutting through the horde and breaking it with a build that grows over the outing; some rooms add noisy work that draws the crowd while their hands are busy. The room's shape is what lets them change tactics mid-fight: fall back to a choke, swing onto a flank, shut a mouth or make for the far door.
	Breathing space is earned in the room's own geometry. The player can clear what came through, slip past it into a part of the room shown to be quiet, or throw a closure that cuts the source off. Shutting a grille stops more from coming; it does not remove what is already inside. Relief is the moment the floor goes still and the work position, the record or the door onward is simply there to use. Curiosity pulls them on: the record that did not quite fit, the far door, the room remembered from another expedition.

	- **Feeding aperture.** The grille, hatch, ward door, mouth or shutter a source releases through, visible before anything arrives. It is never one of the room's walking passages, and closing it never closes a walking passage, clamp path, record continuation or rescue route.
	- **Receiving space.** Floor where arrivals land and turn, beside the work or evidence position rather than over it.
	- **Closure control.** Reachable from the side the astronaut fights on and visible from the entry. A completed closure persists unless its owning mechanism says otherwise; a held one lasts only while held.
+	- **Closing early or late.** Closing a source's access before its release commits prevents that release: nothing comes, no temporary upgrade is offered, and the lasting safety and access remain. A physical seal completed after commitment resolves the stage at once, without waiting for the peak. Either way, bodies already through still need clearing or separation. P01's held shutter and P03's dogged-open shutter follow their own rows.
	- **Quiet.** A closure stops further arrivals but leaves bodies already inside. A space is quiet only when those are also cleared, bypassed into a shown quiet state or physically separated. A rescue starts only on a walked, prepared short route that is quiet or separated in this sense; it needs neither killing everything nor both clearing and closing, and never becomes an escort.
	- **Reuse.** A module shape carries no population. Only the hosts in the first table below carry sources; every other placement of those modules stays quiet, refuge or evidence space.
	- **Living return.** Population holds across a living return: spent stages stay spent, completed closures stay closed and nothing refills or is replaced. A different population variant appears only at a death shift.

	| **R11 R-3 Approach** (E04) | From R01's leg: the bollard; the R12 leg with its gauge and R13's refuge door beyond; the exploration leg with the Flanker pack; and the quarantine-wing grille in that leg's side wall near the junction. The bollard apron is widened where the river turns; the legs keep their width. | **Quarantine ward wing**, a backing volume distinct from occupied R13. A Presser river (25–50 through the junction) pours through the grille and splits round the bollard. **Seal:** the grille's hand-wheel shutter on the junction side of the bollard, visible from R01's leg; the completed closure persists. | Hold R01's mouth as a funnel, work the bollard as hard cover or push to the wheel early; meet the Flankers on their leg. **Work:** walk the exact route, stock and confirm R12, check both controls. **Retreat:** R01's leg, straight to the airlock. | Three walking legs—ship, rescue, exploration—stay open, and closing the grille removes none. The rescue starts only once the route is quiet or separated; R13's inner door is survivor-operated; Sent needs that person aboard with the airlock closed; R12 is the counted abort. |
	| **R14 Pump Hall** (E05 first stage) | From the entry: the tall room, the pump main ending at the back wall, the cable main crossing overhead with its service gantry, the gantry hatch where the main enters the wall, the fixed stair down beside the far pillar, the Boltspitter line, and the addressed workstation and A/B plate on the service apron. The stair lands on open floor with turning space, kept clear of the apron. | **Main service run** beyond the gantry hatch. Bodies cross the gantry and come down the stair (30–60 over the placement) while records are framed. **Seal:** drop the gantry hatch with the chain crank on the near pillar, whose run to the hatch is visible. | Fire up the stair as bodies funnel down; use the pillar against the bolt line; frame records from the apron. **Retreat:** R14's entry threshold. | The floor threshold to R15 is separate from the gantry and stays open; the continuing main defines no route; B face and release. |
	| **R15 Cable Junction** (E05 second stage) | From R14's arm: the cross floor, the labelled bank where the cable main ends, the continuing pump main, the transparent rail with its pressure lane and gate, two cue bays, P04's detents, the Lens exchanger outside the sweep, and in one wall, side by side across the rail post, the open crawl panel and the duct grille. The pressure lane is widened to hold the rail group. | **Cable-duct run.** The rail group enters the lane through the grille and stays behind the rail until its gate state allows, so the Veilbearer's first cast teaches occlusion without ambush. A Boltspitter that survived R14 may walk the cued route behind a later veil. **Seal:** the grille lever on the record side of the rail post. | Cool bays against the sweeps; clamp faces reached from different bays; wait out or route round the veil. **Work:** the record position behind the rail, Lens removal, the crawl test. **Retreat:** R15→R14. | The crawl stays passable and testable; closing the grille leaves it open and promises no far bay. A/R faces and the other arms stay open. |
-	| **R17 Jammed Pressure Approach** (E06; with R20) | From the near threshold: the long lane, both offset pillars, the far threshold into R20, the marked blank panel under the far lamp, the side gallery along one wall with the Flanker pack in it and, between the pillars, two ward doors, one in each wall, with their locks. The lane is widened around the second pillar between the doors. | **Two side wards.** The Flanker-only approach comes first, down the gallery, before the wards are disturbed; it is standing opposition, not a stage. Once the player is mid-hall the wards release one stage (40–80 through the hall). **Seal:** throw both ward-door locks as completed acts; each sits on the entry side of its door, reachable from pillar cover. | Meet the Flankers from the first pillar; move pillar to pillar; use the long lane as a firing line; cut the panel as a candidate bypass. **Work beyond:** R20's valve and caps, with Siphon a special pressure at the valve rather than another stage. **Retreat:** the near threshold, visible from the far end. | R17's long route and panel remain, with no short-rescue qualification. R20 has no source: the crowd reaches it only through the shown threshold, two pillars stay between tether line and valve, and caps stay on different quarters with the dry outer arc. |
-	| **R23 Material Sorting Bay** (E07 host) | From R24's threshold: driver and receiver ends, the protected observation strip, ceramic strips across the Grid seams, both feed clamps, the Cycler cradle outside the transfer path, Veilbearer and Boltspitter. The receiving floor lies between that threshold and the Grid rail, beside, never over, the strip and ceramic routes. | No source in R23. Bodies from R24's hatches walk through the R24→R23 threshold onto the receiving floor. Transfer lines carry no creatures. The closures are in R24. | Lure a finite group across the rail and strike from cover; walk ceramic; wait at the veil sheet's edge. **Work:** operate or frame the corrective pair from the strip; capture; Cycler. **Retreat:** R23→R24, crossing leg floor under the hatches until they are dogged. | Protected evidence refuses Cycler; the Grid arms only from physical rail impacts; in Arrangement B a second threshold leads to R21. |
-	| **R24 Transfer Service Gallery** (E07 apertures) | From any leg: the bollard, the other two legs framing pair records, the closable service recess, three feeding hatches in the ceiling above the legs near their mouths and three dog wheels on the bollard apron. | **Transfer-gallery loft**, one backing volume over the gallery. Its stage drops through all three hatches while E07's pair is operated or framed (30–60 through the placement), and arrivals walk the legs toward the work. **Seal:** dog all three hatches from the apron, each a completed closure. | Bollard cover; each leg is a funnel; dog the retreat leg's hatch first. **Work:** framing angles. **Retreat:** the leg the astronaut entered by. | All three legs stay walkable for records and continuation. The abort recess lies under no hatch, and its door is separate from the dogs, Aster's outside lock at R22 and the transfer machinery. |
+	| **R17 Jammed Pressure Approach** (E06; with R20) | From the near threshold: the long lane, both offset pillars, the far threshold into R20, the marked blank panel under the far lamp, the side gallery along one wall with the Flanker pack in it and, between the pillars, two ward doors, one in each wall, with their locks. The lane is widened around the second pillar between the doors. | **Two side wards.** The Flanker-only approach comes first, down the gallery, before the wards are disturbed; it is standing opposition, not a stage. Once the player is mid-hall the wards release one stage (40–80 through the hall). The locks are mid-hall too, so throwing them seals the stage after its release commits rather than preventing it. **Seal:** throw both ward-door locks as completed acts; each sits on the entry side of its door, reachable from pillar cover. | Meet the Flankers from the first pillar; move pillar to pillar; use the long lane as a firing line; cut the panel as a candidate bypass. **Work beyond:** R20's valve and caps, with Siphon a special pressure at the valve rather than another stage. **Retreat:** the near threshold, visible from the far end. | R17's long route and panel remain, with no short-rescue qualification. R20 has no source: the crowd reaches it only through the shown threshold, two pillars stay between tether line and valve, and caps stay on different quarters with the dry outer arc. |
+	| **R23 Material Sorting Bay** (E07 host) | From R24's threshold: driver and receiver ends, the protected observation strip, ceramic strips across the Grid seams, both feed clamps, the Cycler cradle outside the transfer path, Veilbearer and Boltspitter. The receiving floor lies between that threshold and the Grid rail, beside, never over, the strip and ceramic routes. | No source in R23. Bodies from R24's hatches walk through the R24→R23 threshold onto the receiving floor. Transfer lines carry no creatures. The closures are in R24. | Lure a finite group across the rail and strike from cover; walk ceramic; wait at the veil sheet's edge. **Work:** operate the corrective pair or commit its capture from the strip, which releases R24's loft; Cycler. **Retreat:** R23→R24, crossing leg floor under the hatches until they are dogged. | Protected evidence refuses Cycler; the Grid arms only from physical rail impacts; a proposed second B face at the far end of the receiving floor leads to R21 in Arrangement B without crossing the Grid seams, the strip or the transfer path. |
+	| **R24 Transfer Service Gallery** (E07 apertures) | From the R15 leg in Arrangement B: the bollard, R22's booth and its pair down one leg, the approach to R23's bay down the other, the closable service recess, three feeding hatches in the ceiling above the legs near their mouths and three dog wheels on the bollard apron. R21 cannot be seen from here. | **Transfer-gallery loft**, one backing volume over the gallery. Its stage releases through all three hatches when R23's corrective pair is operated or a capture of it is committed (30–60 through the placement); looking at or recording R21's or R22's clean pair releases nothing. Arrivals walk the legs toward the work. **Closure:** dog each hatch from the apron. With all three dogged before the release commits, nothing comes and no upgrade is offered; after commitment, dogging the last open hatch seals and resolves the stage at once. | Bollard cover; each leg is a funnel; dog the retreat leg's hatch first. **Work:** framing angles. **Retreat:** the leg the astronaut entered by. | All three legs stay walkable for records and continuation. The abort recess lies under no hatch, and its door is separate from the dogs, Aster's outside lock at R22 and the transfer machinery. |
	| **R25 Balance Gallery** (E08, setpiece A) | From the approach threshold: Bellback across the rib, the neutral line and paired plates, Bank vessels and frost indicators, cap control, stirrup, handrail, and both feeding mouths in the outer walls away from the two walking thresholds. The outer floor is widened outside the mechanism footprint; the plates are flush with it and open along their outer edge. | **Two adjacent source volumes.** The phase 2 stage holds 80–150 at once and passes several hundred through the crest. Arrivals cross the outer floor toward the astronaut and, where their path crosses a plate, stand on it and load it. **Seal:** each mouth's closure on the wall beside it; closing one early shrinks the stage, and closing both resolves it. | Shelter at the rib; time the handrail and stirrup; hold one Bank lane; lure or shove bodies onto one plate to steer the tilt; or overpower. **Work:** caps, each a persistent commit; for a rib, two cutter releases and a seated pin, separate commits that fix that one rib while the other still swings. **Retreat:** the approach threshold and protected control. | Walking thresholds unaffected by either closure; only mass physically on the plates counts; widening does not enlarge the plates; no counter-wave after an early clear. |
	| **R28 Regulator Gallery** (E09) | From the approach at the panel end: panel and reply socket, four rack aisles with plates and tells, the fan flank, the Grid rail between pull face and fan flank with ceramic bypass and clamps visible from the protected mark, the grille at the far end of the fourth aisle and the ceiling hatch above the socket. The cross-aisle before the panel and the rear service walk are widened for circulation. | **Rear rack store** behind the fourth-aisle grille: 30–60 enter, cross the rear walk and come down all four aisles. **Ceiling maintenance space** above the socket: a completed Caller call releases a second stage through its hatch; cutting the alarm first prevents it but does not recall bodies already moving. **Seals:** the grille by a pull rod at the fourth aisle's panel end; the hatch by a chain beside the socket; both independent of the alarm lead and the reply. | Aisles as firing lines; fan shelter and flank; lure a rail impact; walk ceramic. **Work:** pull R4, observe the line and test the matching R3 B plate from the protected marks. **Retreat:** the approach threshold. | Nothing depends on R29 or R30; neither volume stores a plate; closures never replace pulling or testing; A face and releases. |
	| **R35 Receiver Vault Approach** (E10, setpiece B; with R36) | From the entry: the widened hall, two pillars spaced to keep the tether lane readable, Siphon radius, Shutterback's shelter angle, the Caller, one feeding mouth in each side wall, and in the far wall a hatch beside R36's opening, with the iris beyond. | **Two side-wall volumes** release the hall stage (80–150 at once). A completed Caller call releases a second stage from the **far-wall volume** through its hatch. **Seals:** each side mouth from a control on its accessible side; the far hatch from a control on the hall side next to, never across, R36's opening. | Choose selector lane, fan flank or clamp route; hold the pillar line against Siphon; cut the alarm before the call completes. **Work:** in R36–R38. **Retreat:** R35's entry threshold. | R36's two side openings remain walking passages to R37 and R38 and are never sealed; R36–R40 hold no source; opening R39/R40 creates no population; without current R35 access, E10 waits. |

	| **M09 Quarantine Ward — R13** | One refuge door opens onto a shallow treatment ward with fixed beds, a wall log opposite the threshold and a quarantined arc grid along a separate service edge. The occupant can operate the inner door without crossing the work lane. | Hosts the sole R-3 occupant, wall record, ward history and Arc source. The grid may be removed without erasing refuge or evidence. This module does not imply every ward is breathable, occupied or connected to the same corridor. |
	| **M10 Pump/Drive Chamber — R14, R27, R31** | Tall machine room with one continuous main crossing overhead, one local machine terminating visibly at the back wall, two pillars and an accessible service apron around the terminating fixture. R14 alone adds a service gantry along the overhead main, a feeding hatch where the main enters the wall and a fixed stair descending to a landing kept clear of the service apron; the hatch chain runs down a pillar within reach of the floor. | R14 compares pump/cable mains, R27 exposes exchanger removal, and R31 turns the geometry into Foundry's outward blue-double pulse. R27 and R31 carry no source. The repeated shape lets earlier “which main ends” evidence reinterpret a later converter candidate; identical architecture does not establish identical purpose, and the gantry is R14's fitting, not the module's. |
	| **M11 Cable Junction — R15** | Cross-shaped cable room with the heavy cable main terminating at a labelled bank while a pump main continues through. An open wall panel reveals a crawl edge; a transparent rail separates one visible pressure lane from the record position. A cable-duct grille sits in the same wall as the crawl panel, on the pressure-lane side of the rail post, and feeds that lane behind the rail gate; its closure lever is on the record side of the post, and closing it leaves the crawl open. | Hosts builder-run comparison, wall-access case, Thermal Lens, visitor continuation mark, A/B/address evidence and the placement-5 Veil/Bolt relation. Removing Lens chills only its exchanger. The crawl may block and never promises its historical far bay is currently reachable; the grille is never a route. |
-	| **M12 Sampling Loop — R20** | Circular pipe walk around a central sample line; cap controls sit at two quarter points, the local impact plate/Dynamo at a third, and the pressure regulator core at a reachable service gate. Two pillars interrupt the Siphon line. | Hosts objective 6's durable cap stages, Breath Bank, Dynamo, regulator assembly and source-side counter observation. Its loop supports withdrawal after one cap. It cannot become a short rescue route or let remote impacts trigger the local clamp. |
-	| **M13 One-Way Transfer Bay — R21, R23** | Two clearly separated end fixtures in one room: a driver visibly pushes through a line and a receiver visibly fills. A protected observation strip sees both; the material cradle, if present, sits outside the transfer path. R23 alone adds a receiving floor on its approach side, between its walking threshold and the transfer floor and beside, never over, the protected strip and ceramic routes. | R21 supplies the clean first pair; R23 supplies the corrective third pair, Cycler and a screened encounter whose crowd arrives through its walking threshold. R21 carries no source, and transfer lines are never creature routes. Reuse must change what is tested—direction first, cross-register/body-slot and removable sorter later—not merely the colour of a pipe. |

Reuse must change what is tested—direction first, cross-register/body-slot and removable sorter later—not merely the colour of a pipe. |
	| **M14 Decontamination Booth — R26** | Dirty and clean thresholds flank an air curtain, with a fixed rib, a side culture rack and a removable wall slab beside an ordinary standing passage. Separate service faces show the existing fixed transformation: forward accepts A and emits B; reverse accepts B and emits A. A manual inner control is reachable by the refuge-side person. | Hosts Mara's distinct rescue rack, wall-access discriminator, Nozzle source, short transfer and the early reversible Decontamination A↔B observation used by the candidate network. Mode and pulse direction are visible and persist separately from walking access. Purging the rack never consumes Story30 cultures; removing Nozzle stops only the air knife, not the fixed service transformer. |
	| **M15 Balance Gallery — R25** | Broad gallery centered on a neutral line, fixed rib and occupied maintenance stirrup. Breath Bank draw lane, Phase-Balance chamber and cap control are visible from the entry; waiting Pressers are visible before commitment. Two feeding mouths in the outer walls, away from both walking thresholds, open onto a widened outer floor; the paired plates stay flush with it and open along their outer edge, so bodies crossing toward the astronaut can walk onto them. | Hosts placement 8/setpiece A and one exchanger-core checkpoint. Durable cap/pin work changes later traversal. The gallery can be overpowered or crossed with cover/timing; it adds no reactive population and is not a generic arena shell. Widening the floor does not enlarge the plates. |
	| **M16 Four-Rack Regulator Gallery — R28** | Four parallel regulator bays face one panel and reply socket. Each rack's plate, physical tell and pry access are visible without entering the others; a side fan creates one readable occlusion angle. A rear service walk links the aisle ends. The fourth aisle ends in a feeding grille from a rear rack store, and a maintenance hatch in the ceiling above the reply socket opens from a separate overhead space; both volumes belong to this room and both routes are visible from the panel. | Hosts R1–R4 A/B chronology, the reply protocol, Capacitor source and placement 9. Pull order can lose evidence but not basic work/reward. Neither source volume stores a plate or depends on a neighbouring room. Reuse elsewhere may borrow the rack grammar only if it preserves per-fitting identity and before/after observation. |

The wards release one stage once the player is mid-hall. Cutter stages test the candidate bypass; Siphon is previewed before loop work. | Language-first order gives a reason to cut; build-first can complete via long route and reinterpret the mark later.

The receiving floor lies between the R24 threshold and the Grid rail, beside the protected strip and ceramic routes; bodies from R24's hatches arrive through that threshold. | Corrects accidental reversal; removing Cycler stops sorting but preserves transfer evidence and Grid state.

+	These are eligible paper arrangements, not generated maps, simulations or promises of universal reachability. Unlisted rooms remain elsewhere in the same arrangement; a route shown here does not reveal them. Each route step below is a **walking adjacency**: two thresholds standing open to each other in this arrangement, crossable now. That is not a persistent join, which still needs a compatible pair, the latch preview and its hand-cycle, and it carries no directional network signal, which only faces with input or output arrows can pass.
	### Arrangement A — build-and-ship first, with one valid short rescue
@@ 210,13 211,13 @@
	In the current proposed **Arrangement A**, R01's one outer threshold leads only to **R11**. R11's three legs are: R01 entry, **R12→R13** rescue branch, and an exploration branch toward R17. Thus the rescue route is **R01→R11 (one contested junction)→R12 (stocked abort vestibule)→R13 (R-3 refuge)**, not a second R01 exit. The astronaut walks this exact current route, checks flow and both controls, and makes the crossing quiet or separated—cleared, bypassed into a shown quiet state or cut off by a persistent local closure—before transfer. Yeva or Aster operates the R13 inner door, walks under their own power and may call abort. Ordinary abort reaches R12; Sent exists only after that same person reaches the ship and its airlock closes. The encounter does not move with them or grow into another junction.
-	R11's exploration leg currently reaches **R17**, whose far threshold opens into **R20**; R20's second walking threshold opens into **R25**, and R25 leads on to R26–R27 for Balance/Nozzle/exchanger. This order is revised so that the allocated ordinary encounter at R17/R20 comes before setpiece A; Trace A below gives the checks. Gauges allow objective 6 before formal language work; later records from R14/R15 and R21–R23 reinterpret the already captured pressure destinations. R20's completed caps and removed Dynamo remain true, while any later death makes these current routes historical. Installing all four assemblies aboard exposes objective 10's bounded readiness report, not departure or credits.
+	R11's exploration leg currently reaches **R17**, whose far threshold meets **R20**'s B face; R20's second walking threshold, its proposed A face, meets **R25**'s A face, and R25 leads on to R26–R27 for Balance/Nozzle/exchanger. The ordinary encounter at R17/R20 therefore stands between cleared R11 and setpiece A; Trace A gives the checks and the travel cost.

R20's completed caps and removed Dynamo remain true, while any later death makes these current routes historical. Installing all four assemblies aboard exposes objective 10's bounded readiness report, not departure or credits.
	This arrangement makes no claim that R18 is also reachable through R12. In any later eligible arrangement for Dorn, R18's side route must be walked while the direct boundary remains sealed. Choosing the direct hoist opens it persistently; only after the astronaut walks the newly exposed route and finds it short may rescue proceed. Finding an extra junction leaves the opening committed and Dorn waiting; a separately verified current side route remains the honest alternative.
	### Arrangement B — language-and-network first, with honest rescue deferral
-	R01's outer threshold meets **R14**, whose floor threshold meets **R15**. R15's arms lead back to R14, on to R11 and on to **R24**; its crawl is a test, not a route. R24's other two legs reach **R22** and **R23**, and R23's second threshold opens to **R21**. The player records builder mains and visitor transfer pairs, visits R08 for the first latch, and uses gauges plus those predictions at R17/R20. In this arrangement R-3 is reachable only through **R14→R15→R11→R12→R13**: two exposed junctions lie between airlock and refuge, and R12's ship-side abort path is not current. The R-3 person remains waiting. A bearing, a photographed wall string and knowledge of the old route cannot compress it; no staged refuge chain or long escort appears. The player pursues other objectives until a later arrangement yields a genuinely short walked route.

	At R28, physical pull/reply work makes responsive procedure concrete before R36. R35–R38 then offer direct or two-clamp equalisation, opening R39/R40 without language as a gate. Suppose R40 was seen first: its opposed faces and two kinds of control are recorded but not understood as a recovery pattern. A later visit to repeated module M06 at R08 teaches that walking latch and network-side release remain distinct. Returning to reachable R40 lets the player identify the analogous physical release while keeping the profile-isolation control conceptually separate. If R08 was visited first, the same insight applies forward. The module earns reinterpretation in either order without a required chronology.

	Both traces follow a living return in an unchanged arrangement. Nothing shifts, nothing refills, no seal pays twice and no death is needed. Temporary upgrades and unchosen offers were lost aboard; carried property, completed work and knowledge remain. A **mouth** is a feeding aperture; a **reward stage** is a sourced release that pays once when cleared or closed; a **work stage** is a world-time step on a mechanism or objective, which pays nothing and may warn again from neutral.

-	**Why the arrangement changed.** As first proposed, R11's exploration leg met R25 directly. After the rescue, the next expedition would cross cleared R11 and arrive at setpiece A with the starting rig and no ordinary stage first. The revision puts the allocated ordinary encounter E06 in between: R11→R17→R20→R25, with R26–R27 beyond.
+	**Route.** R11's exploration leg leads to R17, R17 to R20 and R20 to R25, with R26–R27 beyond, so the ordinary encounter at R17/R20 stands between cleared R11 and setpiece A.
-	**Checks.** *Walking:* each step uses one current threshold: R01→R11's ship leg; R11's exploration leg→R17's near threshold; R17's far threshold→R20; R20's second walking threshold→R25's approach threshold. *Rescue:* R01→R11→R12→R13 is unchanged, with one contested junction. Mara's route to R26 now crosses R11, R17, R20 and R25, so her rescue waits in this arrangement, as it already did; Dorn and later Yeva stay unclaimed. *Discovery orders:* the build-first player uses R17's long route and R20's gauges before any language; a player holding R04's marked-wall capture can choose the cutter panel instead; R14/R15 records reinterpret R20's destinations whenever they arrive. Breath Bank is now met at R20 before R25, matching the Encounter inventory's assumption that its warning is learned at P05. *Boundary:* E08's withdrawal crossing becomes R25's threshold toward R20.

	**Checkpoint.** The rescue expedition resolved E04 by closing the quarantine-wing grille and cleared the bodies already inside, so the route was quiet. It stocked R12, captured R13's wall log, and brought the R-3 survivor aboard with the airlock closed: Sent. E04's temporary upgrade and any unchosen offer were lost aboard.
	**The next expedition.** R01 is unchanged. In R11 the bollard apron is still, the grille wheel stands closed where it was left, and the R12 leg leads to an empty refuge. Nothing has refilled. The exploration leg opens onto R17.
-	**First unresolved source.** From R17's near threshold the player sees the long lane, a Flanker pack in the side gallery and, deeper between the pillars, two ward doors with their locks: E06's one reward stage, which releases once they are mid-hall. The Flankers are standing opposition, not a stage. *Knowledge-led choice:* R11 taught that a closure resolves a stage as fully as clearing it, so the player can plan a pillar-to-pillar line that reaches both locks before the peak. A player holding R04's marked-wall capture can instead cut R17's marked panel as a candidate bypass.

A player holding R04's marked-wall capture can instead cut R17's marked panel as a candidate bypass.
	**Baseline without upgrades.** Meet the Flankers from the first pillar with the starting rig; move pillar to pillar; throw the near lock, then the far one; clear or slip past what already came through. The near threshold stays visible as the retreat. Escaping earns nothing, and re-entering resumes the same stage.
	**Beyond.** R20 holds work stages under pressure, not further reward stages: the Bank caps and the regulator-core assembly, with Glass Siphon as a special pressure at the valve and the Dynamo nearby. R25 follows with the setpiece's reward stage from two mouths, and P07's caps and P08's rib releases as work stages. Nozzle and the exchanger core wait in R26–R27.
-	**The return after that.** Once E06 is spent too, the next expedition crosses R11, R17 and R20 before reaching R25, with no stage between. R20's Bank phases warn again from neutral unless a cap was closed, which is pressure without reward. This walk is longer than the original R11→R25; R17's panel is only a candidate bypass, so no shortcut is claimed, and the setpiece keeps its baseline approach. As cleared ground grows, the frontier recedes; this page does not solve that.

R15's third arm opens onto R24.

The loft is E07's reward stage, released through the hatches when the corrective pair is operated or framed. *Knowledge-led choice:* R14 and R15's address plates point to R23's third workstation as the test that matters. R15 showed that a veil invalidates targets and that closing a source resolves its stage. So the player may frame from the ceramic strips and dog the entry leg's hatch first to keep the retreat.

The station becomes a set of persistent places the player can remember and physically assemble, not forty interchangeable skins.

Twelve rooms first authored for small fights now reserve receiving floors, apertures and closures; that is real layout work, and it risks making discovery rooms look alike. Revised Arrangement A lengthens cleared travel to setpiece A. Three signature families, a reversible converter, Decontamination mode and one fixed converter may still be too much network notation—or too little late-puzzle depth.
