	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.
-	Coming back alive, the rooms they quieted stay quiet and the openings they closed stay closed. Their temporary strength is gone. The next expedition crosses remembered, quiet ground to the first opening that still holds something, and meets it with the rig they started with.
+	Coming home ends temporary strength. Each new expedition brings fresh crowds and regular combat growth while permanent openings, seals and room connections remain changed. A familiar route can offer a new climb, but its renewed sources and approaches must fit the work the player already completed.
-	**How this could fail.** Crowd space and discovery space compete. If every evidence room grows a broad receiving floor, rooms start to look alike, records end up inside arenas, and the station loses the specific places the player is meant to remember. If only the great galleries carry crowds, ordinary travel loses its horde. The geometry below reserves space and names the layout work still required. How crowds behave is owned by [Combat Rules](/Hold%20The%20Flood/Combat%20Rules), what a resolved release pays by [Build Rules](/Hold%20The%20Flood/Build%20Rules), and each fight's sources and stages by [Encounter And Mechanism Placement Inventory](/Hold%20The%20Flood/Encounter%20And%20Mechanism%20Placement%20Inventory).

	## What this inventory covers
@@ 22,7 22,7 @@
	A wall panel, evidence drawer, reply face, manual bypass, fixture alcove or glass observation cell inside a room is not a free room. A vestibule counts only when it is separately traversable, threshold-delimited and owns a distinct refuge, recovery or route action. A mechanism may span faces in two rooms; each face belongs to its room, while the mechanism has one placed identity. The ship airlock interior, berth, home deck, packing bench, receiver, ledger table, material tray and gait rail are **ship spaces and fixtures, not playable station rooms**. Objective 10 occurs aboard and therefore adds no station room.
-	For every room, stable facts are its identity, module, fixtures, completed local checkpoints, installed/dropped objects, committed captures and selected joins. Current facts are unbound neighbours, orientation, transient power, live population (held across a living return and changed only at a death shift) and unobserved accessibility. A death returns carried property, advances one arrangement, preserves the stable facts and makes prior route/adjacency records historical. **What moves is a rigid unit:** each compact assembly and each latched group holds one internal pose, and an unanchored group may translate and rotate only as a whole, never reflect or stretch its interior. The **ship-rooted group containing R01 is anchored** and neither moves nor turns, so a shift changes which unbound group meets the ship-rooted group's free outer frontier — never which room touches the airlock. Loading, a journal visit or a survivor statement does not shift, complete, locate or connect anything. All capture and work actions happen while the game runs; the journal pauses everything.

All capture and work actions happen while the game runs; the journal pauses everything.
	Two cross-room systems have explicit compact boundaries. **R02 Cargo Turn and R03 Collar Control are one two-room collar-service assembly:** their walkable throat and hard control conduit move together, while the assembly's external faces may change; this preserves the opening board/rack relationship without making either room free. **R36–R40 are one five-room core-boundary assembly:** iris, two clamp rooms, evidence cell and isolation hall keep their internal passages and control lines. This is a placement rule: it changes no interior geometry and does not make any optional exterior approach fixed. R35 is only a current exterior approach; if it is not adjacent and reachable, objective 11 waits. Joining either compact assembly to the ship-rooted network counts all its rooms only after every interior room is actually reachable.

	- **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.

	- **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.
-	- **Growth.** Every source, closure and baseline approach below stands whether temporary growth comes only from resolved stages or also from defeated enemies and milestones.
+	- **New expedition.** Combat populations and growth opportunities renew after living return or revival. Living return keeps the room arrangement; death also shifts unjoined rooms. Permanent closures and other completed work remain changed, and new arrivals need viable sources and routes consistent with them.
+	- **Growth.** The owner selected regular fighting growth with larger transformations at major horde milestones. [Combat Rules](/Hold%20The%20Flood/Combat%20Rules) owns its proposed cadence and milestone conditions; source and closure states remain physical facts. E06 and R25 below map the representative route; other placements and permanent-seal configurations still need their mapping.

	|---|---|---|---|---|
	| **R02 Cargo Turn** (E01; with R03) | From R01's threshold: the entry lane, the board and part cradle at the inside corner, the waist-high rack at the bend and, past it, the second lane ending at the patient-bay shutter with P01's floor frame and preview lamps in front. Both lanes are widened for a standing crowd (20–40); the bend stays the choke. | **Patient-bay ward**, a backing volume on the rigid R02/R03 assembly. The noisy final fastener or a completed Caller call releases its stage (40–60) through the shutter, across the frame and round the bend. **Seal:** P01's completed manual dog hand-cycle with the shutter across that lane; the dog sits beside the frame, reachable before it. A shutter held by the board or by the Fork Relay (the splitter) only suppresses the stage while held, and an undogged shutter returns neutral on withdrawal or death. | Hold the bend with the rack breaking one lane; install Fork so the board holds rack and shutter together, or carry it and fight the open lane. R03's fastener work is visible across the fixed throat. **Retreat:** R03→throat→entry lane→R01, never crossing the frame or the shutter lane and never depending on shutter state. | Fixed throat and conduit, releases in both rooms, the no-Fork selector path, R03's fasteners and bridge identity. The standing crowd is not a stage. |
	| **R05 Pace Calibration Bay** (E02) | From the entry threshold the bay reads end to end: grounded interval, belt with return drum and stop, gait plate at the near end, pillar and Boltspitter line, P02's painted sector, cool bay and entrance-side clamp, and the duct grille at the far wall. Receiving space is a short apron beside the return drum past the last floor mark, then the open side lane opposite the belt. The bay is not widened into a hall. | **Belt-return duct** beyond the far wall. A thin continuous stream (15–30); starting either gait capture wakes it fully and it thickens while the captures run. Arrivals walk up the side lane and cross the interval only to reach the astronaut. **Seal:** drop the grille from the hard-cover position off the measurement line, through its visible linkage. | Pillar against the bolt line; cool bay reachable without entering the interval; alternate observation, movement and work. **Work:** the grounded pass and the feet-still belt ride. **Retreat:** the entry threshold at the plate end. | Every gait and belt endpoint, the return and the stop stay inside R05. The duct is neither the belt route nor R07's housing. Ivo's refuge door, his retreat to stocked R06 and the external face stay separate. |
-	| **R08 First Local Latch Hall** (E03, later variant only) | First lesson: one Clampcrawler in a quiet hall, count lamp empty. Later death-shift variant: the count silhouette of the occupied holding volume behind the opaque alarm-only shutter at the end of the branch P03's frame intersects. A side holding apron between that shutter and the centre island is widened for the later crowd (20–40). | **Holding volume**, reached only through the closed opaque shutter, with no mutual sight. A completed P03 alert opens the route; cutting the exposed lead before commitment prevents the stage; a cut after commitment neither closes the route nor recalls the crowd. **No seal:** P03's persistent commit dogs the shutter open, so this stage resolves only by clearing. A dogged-open shutter stays open and excludes the closed-holding variant; it is never closed again to stage a crowd. | Island cover and opposed-face sightlines; the latch work position sits inside the Crawler's arc while the side step and R09 retreat lie outside it. The apron's lane never takes the side step or blocks the network-side release. **Retreat:** R08→R09. | Introduction-seen bit set on entry to the first lesson; no creature on a same-life retry; both-side releases; no second shutter or latch. |

	| **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). 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. |

The lane is widened around the second pillar between the doors. | **Two side wards.** The Flanker-only approach comes first, down the visible gallery, before the wards are disturbed; it is standing opposition, not a release stage. Once the player is mid-hall the wards release one physical stage (40–80 through the hall). For ordinary growth, the standing Flankers and the two ward portions are three visible pressure bands, with a Break Mark preview at the gallery approach and each ward door. Fresh expeditions renew these groups only through their viable approach and still-unsealed doors. 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. Completed cutter work at the marked panel opens a narrow two-way local service passage from R17's near side to its existing far threshold into R20. Take the long lane outward for its bands, or use the passage as a bypass and safer return. **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 permanent local passage remain, with no added room, source, objective or station-joining face and 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 limited 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 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. |
+	| **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; growth and milestone consequences follow Combat Rules; 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. |

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. Still-unsealed mouths renew for a new expedition and split their finite release into visibly announced pressure bands; each mouth previews its actual future unpaid marks. The major opportunity remembers a committed mouth band and a valid Bellback answer in either order, as detailed in E08 and Combat Rules. 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. |

	| **M03 Glazed Control Cell — R03, R07, R30** | Compact control room with glass toward the operated fixture, a rear retreat threshold and a side service face. The operator can inspect result before committing the next stage but cannot operate safely from outside. | R03 exposes rack/shutter and bridge fasteners, R07 exposes navigation-coupler release, and R30 records regulator-panel before/after states. Reuse earns distinct extraction, assembly and evidence work; glass never grants remote operation or unseen-room knowledge. |
	| **M04 Split Service Junction — R06, R10, R11, R24, R38** | Three-leg T junction with a central fixed bollard, two visible branch mouths and one shallow service recess. A worker at the recess yields the centre and can be approached from either branch. The base form has no feeding aperture. A host adds a source only where its row says so—a side-wall grille (R11) or hatches above its legs (R24)—and then keeps all three legs walkable, widens only the bollard apron and puts the closure controls on that apron. | R06 supplies the pace-bay approach and Ivo abort recess without containing the belt, R10 supplies a controlled signature refusal, R11 makes the R-3 side lane one leg rather than a long escort, R24 gives transfer records distinct viewing angles, and R38 is the second-clamp flank. R06, R10 and R38 carry no source. The module supplies a readable choice of lanes, not a permanent relationship among whatever rooms currently occupy its branches, and reuse creates no population. |
	| **M05 Pace Bay — R05** | Long marked floor interval parallel to a slow service belt; both begin and end inside the same room, together with the belt return and manual stop. A detachable gait plate sits at the approach end, with hard cover off the measurement line. Past the far floor mark a belt-return duct opens onto a short apron beside, not inside, the return drum; its grille drops from the hard-cover position through a visible linkage, and arrivals walk up the open side lane opposite the belt. | Hosts the same-astronaut voluntary-grounded versus carrier comparison, Stride source, Ivo variant, one Boltspitter cover lesson and a thin continuous stream rather than a hall crowd. It cannot treat survivor steps, recoil, shove or a rolling weight as the established Stride event, and the duct is neither the belt route nor a neighbour's housing. |
-	| **M06 Two-Face Service Hall — R04, R08, R40** | Rectangular hall with opposed visible service faces, a centre inspection island and release controls reachable from the interior/network side. One face can be studied without touching the other. R08 alone adds a side holding apron beside the island and one opaque alarm-only shutter into a non-playable holding volume, used only by its later death-shift variant; the apron never takes the island's side step or the path to the release. | R04 separates wall mark from pressure door, R08 teaches compatible join/refusal/release, and R40 uses the same readable separation for the profile-isolation boundary. R04 and R40 carry no source. Reuse makes old release geometry newly meaningful, but latch compatibility does not explain biological coupling and an isolation mode does not release a walking join. |

	In **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 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.

-	**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.
+	**Route.** R01→R11→R17→R20→R25. R11's rescue leg remains R12→R13; R17's existing far threshold meets R20's B face, and R20's A face meets R25. There is no extra ship exit.
	**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's B face; R20's A face→R25's approach threshold at its A face. *Rescue:* R01→R11→R12→R13 is unchanged, with one contested junction. Mara's route to R26 crosses R11, R17, R20 and R25, so her rescue waits in this arrangement; 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 met at R20 before R25, matching the Encounter inventory's assumption that its warning is learned at P05. *Boundary:* E08's withdrawal crossing is R25's threshold toward R20.

+	**Checkpoint.** The rescue expedition closed R11's quarantine-wing grille and cleared the bodies already inside, stocked R12, captured R13's wall log, and brought the R-3 survivor aboard with the airlock closed: Sent. On the earlier ward-hall visit, the astronaut fought through R17 without permanently locking its wards. R04's marked-wall capture made the panel an informed cutter test. Completed cutter work opened R17's narrow two-way service passage from its near side to its existing far threshold into R20. Returning alive kept this arrangement and every permanent change, while ending temporary power.
-	**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.
+	**Fresh pressure.** R11's closed grille sends no new bodies. Sound and movement on the exploration leg warn of the fresh Flanker band in R17's visible side gallery; alerted Flankers can follow through the shown near threshold. Both still-unsealed wards hold fresh Pressers and release through their own doors. The gallery approach and each ward door show one band preview. The long lane retains two pillars, its two hall-side locks and one physical ward-release stage of 40–80; the standing pack plus two ward portions are three growth bands, not three new releases.
-	**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:* the locks sit mid-hall, where the release commits, so here a closure cannot prevent the stage, only seal it early. R11 taught that a completed seal resolves a stage at once, so the player can plan a pillar-to-pillar line to both locks instead of waiting out the crest. A player holding R04's marked-wall capture can instead cut R17's marked panel as a candidate bypass.
+	**Outward choice.** With the starting rig, meet the Flankers from the first pillar, then move along the long lane. Breaking the pack and both ward bands banks one ordinary Tune before R25. A queued Tune and partial progress survive taking another choice or retreating within this expedition; [Combat Rules](/Hold%20The%20Flood/Combat%20Rules) owns the detailed queue and thresholds. The player can take a choice during the journal's full pause or keep fighting. Throwing the ward locks stops their access, not bodies already through; each seal previews the actual uncommitted marks it would prevent. The local passage is also available outward, forgoing these bands rather than granting their growth. R25 retains its no-upgrade baseline.
-	**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.
+	**Work and climax.** Earn quiet by clearing or separating the arrived bodies, then inspect the panel and its lamp/crew-name sightline. R20 has no source: only real, visible followers from R17 plus the existing Glass Siphon can apply creature pressure there. Its Bank caps, regulator-core assembly, Dynamo and source counter retain their own work and property rules. At R25, the two unsealed mouths announce finite bands. The mouth commitment and Bellback answer are remembered in either order, and the gallery shows which fact has occurred. Leaving the locked cone, sheltering at the rib through its wave, catching it with a faced Barrier, interrupting the unfinished brace by displacement, or defeating Bellback can supply the answer. When both facts exist, transformation ready appears once while later crowd remains. No immunity or replacement creature protects the milestone. Caps and rib pins remain physical work; Nozzle and the exchanger core remain in R26–R27.
-	**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.
+	**Return and next visit.** The completed R17 passage provides the local return shortcut; it does not automatically qualify any survivor route. Going home ends the temporary climb again. R11's seal and the passage remain, and fresh bands can return through R17/R25 sources that are still viable. R20's Bank phases warn again from neutral unless a cap was closed. This trace covers that explicit open-ward/open-mouth configuration. It does not establish renewal after all ward doors or gallery mouths have been permanently sealed, or after a shift changes an external neighbour.
-	**The return after that.** Once E06 is spent too, the next expedition crosses R11, R17 and R20 before reaching R25, with no award stage between. R20's Bank phases warn again from neutral unless a cap was closed, which is pressure without reward. It is a long cleared walk; R17's panel is only a candidate bypass, so there is no shortcut, and the setpiece keeps its baseline approach. As cleared ground grows, the frontier recedes.

These choices change pressure and access; their growth and milestone consequences follow Combat Rules rather than a guaranteed choice for stage resolution.
	**Baseline without upgrades.** Walk the ceramic strips; use the Boltspitter's locked line to lure one rail impact; wait out the discharge; frame from cover, since R15 showed that a veil invalidates targets. Dog the hatches first, or step back to the apron to dog them once the release has come, and clear or slip past what landed. The retreat runs R23→R24→R15.
-	**Beyond.** R21 is a dead end in this arrangement: its one face is the threshold from R23, and its clean pair has no stage. R22's booth is next to the apron.

Further crowd sources in this arrangement lie off this branch: R17's side wards, R28's rack store and ceiling space, and R35's mouths. On another expedition, renewed crowds must fit the surviving open routes and permanent hatch states. P04 still warns unless locked. The full renewal mapping for this branch remains to be designed.

	**Strongest useful experience.** A familiar spatial grammar gains a different meaning: a pump-shaped room teaches that architecture is not purpose; a two-face hall first teaches recoverable joins and later helps separate walking access from biological isolation; old language and pressure records make a later action intelligible without turning notes into a map. The station becomes a set of persistent places the player can remember and physically assemble, not forty interchangeable skins.
-	**Accepted costs.** Forty room identities still require forty distinct state/revisit briefs and later layout work. Multi-room encounters and the iris need careful boundary ownership. Seven rescue-host variants across six rooms increase arrangement constraints. Publishing a 40-room roster exposes a known hidden count. Twelve rooms first designed for small fights now reserve receiving floors, apertures and closures; that is real layout work, and it risks making discovery rooms look alike. Arrangement A's route makes the cleared walk to setpiece A long once R17/R20 is spent, and R20 and R23 each need a second face. 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. Zero added rooms depends on future geometry fitting every named refuge, fixture and release inside these counted rooms.
