**What this page is.** The one statement of the shared rules, which every district, enemy, item and colony service must obey. Everything here is a proposal and nothing is owner-approved or played. A district may add to this contract with a readable signal and the choice the addition improves, published as a shared-rule diff (section 7); it may not change what power, signal, a beacon or charge means. Where this page states a rule in one sentence and a domain page states it in full, the domain page owns the detail and this page owns the sentence; the ownership map is in section 10.
**What r3 established (kept).** Eight cells and player-set collection priority (D023); dispatch needs the drum and the trunk, arrivals need supply, the empty flash is a state (D024, REV104-1, -3); fixed power has a source under Answer A with the Stop cascade and the baseline return (D024, REV104-4, COL-I4); the precedence stack, bounded press, glow as one bit, the Carrier's mote, the Grounder allowed, the arc bounded (R1, R2, R4, R5, R9; R10 declined).
-
**What r4 changes.** Section 1: lines conduct when dry. Section 2: fixed power energises a lit branch's channel water continuously; the Grounder's consequences; the race is unfed, not special. Section 3: a flash needs no power; pursuit range is about ten metres; the press bound is checked against the merged third-dispatch crowd. Section 4: the intensity rule; the Spark row; collection is walking over. Section 6: what persists. Section 9: the refuge's circuit and the declined reserve; grounded runs do not persist. Section 10: the dispositions, including Equipment's countersignature and Combat's pending one.

**What r5 changes.** Section 3: Stop as the brake on time; the floater stays in water. Section 1: the cable reel as U6. Section 2: the C2 request declined. Section 4: the Spark row final. Section 9: Stop without the empty flash; the lift. Section 10: the dispositions.

- Current present anywhere in a body of connected water is present everywhere in it. Two channels are one body when a valve, lock or breach joins them and both hold water. A dry bed does not conduct; a drained connection is no connection. Flowing water conducts exactly as still water does; a channel that carries no current is unfed, not non-conducting, and a district that wants a break in conduction must draw a dry one and show it.
- Lines conduct when dry: cables and rails carry current along their length. A dry bed, loose cargo (crane parts, bundles on dry ground) and equipment housings do not.
-
- Ways to change the topology, all readable on the ground: a valve (joins or parts two channels), a drain or field pump (empties a channel), a lock (moves water between basins; Campaign 3.1), the hand pump (a carried drain, section 5), and the cable reel (a laid conductor between two wet points across dry ground; it carries environmental power only and never charges a battery).

- Ways to change the topology, all readable on the ground: a valve (joins or parts two channels), a drain or field pump (empties a channel), a lock (moves water between basins; Campaign 3.1), the hand pump (a carried drain, section 5), and the cable reel (Equipment's U6: one end clamped to an exposed power terminal, up to about six metres of laid line, the other end to a second terminal, so a dead line is bridged from a live one; it carries environmental power only and never charges a battery).
- In the rack, only orthogonal cell contact conducts. Equipment housings do not conduct, so any module, the insulation included, and any empty cell breaks a salvage chain; wet salvage bundles conduct into touching bundles, and a battery leaks one unit per minute per wet bundle reachable from its terminals through such a chain, capped at the charge present, shown as one drip per bundle. Two batteries reaching the same chain both leak; leakage never powers anything and never hurts the surveyor. Insulation worn as a module is also what lets the surveyor stand in energised water. (Owner of the detail: Inventory and Charge, E2.)
- These are game rules and not a claim about real electrical safety; the Reference pages on electricity in water and drainage engineering record the caveats.

- A device works only while the water, rail or line it stands on carries current, and stops when the current stops. Devices: dispatch beacons, hatches and doors, gates, pumps, lifts and indicator lamps.
- Sources of current: a district's own circuit, switched from its panel, whose positions choose which branch is powered and are exclusive (one branch at a time, or off); and a coil discharge, which energises the water the surveyor is touching for two seconds and stuns the conducting bodies in it for eight (section 4). The thick cable is the power line; switching it is instant and priced by what it darkens as well as by what it lights.
-
- **A lit branch's channel water is energised for as long as the branch is lit** (Combat's question C2, ruled yes): it is why the electrician waits in the lit yard in insulation, and why a discharge into a lit channel adds a stun and no new hazard. Fixed power hurts the uninsulated surveyor and does nothing to organisms (the intensity rule, section 4).

- **A lit branch's channel water is energised for as long as the branch is lit** (Combat's question C2, ruled yes): it is why the electrician waits in the lit yard in insulation, and why a discharge into a lit channel adds a stun and no new hazard. Combat r5's recommendation that fixed power not energise open channel water was written against r3 and is declined: the collection-without-insulation rationale for the two-second window concerns water no lit branch feeds, the head basin and the flats, not the electrician's lit yard, and the scenes on both pages are priced on this row. Fixed power hurts the uninsulated surveyor and does nothing to organisms (the intensity rule, section 4).
- **What supplies the district circuits (provisional, D024, Answer A).** The city runs on charge harvested from the Flood: the Collector's wheels take charge from the mass passing through, the head-works' switch-house stores and distributes it along the thick cables, and each district's panel switches its share. The store is what makes fixed power feel fixed: it outlasts any one expedition. The Stop position at the head-works ends the harvest, and the districts go dark one by one as the store drains (section 9); no district may depend on a supply the table in section 9 does not name.
- **The relay** is the one stated exception in the districts so far: it is a source of signal, not a consumer of power. Its drum is turned by a wheel in the race above the weir, which is unfed water: no lit circuit joins it, the valves join only below the weir, and the actual dry breaks are the weir's crest, the dry gallery and the cables themselves. Drain R stops the wheel and touches no power (World and Mystery r18 and r22, closing REV103-9). The exception is readable: the wheel turns in water that shows no arcs.
- **A role may darken a beacon.** The Grounder (Enemies) climbs a live cable run and grounds it, so everything on that run loses power, beacon and hatch alike, until the body is killed or the branch re-switched; there is no alternate supply on a run. This passes section 7's test: it makes devices stop for want of current, and can never make a light, cause a dispatch or select an intake. Its signal is an irregular flicker that is visibly not the travelling dispatch pulse, a spark at the body's position on the thick cable, and the forecast marking the branch failing (R9 allowed, Combat's C4 ruled; World owns the body's fiction).

## 3. Attraction: the signal chooses the intake; light draws the crowd
-
- **Dispatch (D024, REV104-1).** A district dispatches when its drum's contact closes and the trunk is carrying time: the drum makes the moment, the trunk permits it. Shut stops the drum; a dark position on the Exchange's bank withholds the trunk; either alone stops announced surges. A dark district is in the shut regime, unannounced trickles that grow and a dark forecast, and never a district with no Flood in it; its arrivals obey ordinary targeting once inside.

- **Dispatch (D024, REV104-1).** A district dispatches when its drum's contact closes and the trunk is carrying time: the drum makes the moment, the trunk permits it. Shut stops the drum; a dark position on the Exchange's bank withholds the trunk; either alone stops announced surges. Stop at the head-works is the brake on the shaft that keeps time, so after Stop no district is permitted: no dispatches and no flashes anywhere, the drums turn to no effect, and the Flood arrives by each district's sluice as trickles that grow, the shut regime everywhere (REV104-12, chosen; World r22's rows say the same). A dark district is in the shut regime, unannounced trickles that grow and a dark forecast, and never a district with no Flood in it; its arrivals obey ordinary targeting once inside.
- **Intake and supply (REV104-3).** At a dispatch the chosen intake's beacon flashes, and a surge enters there if the supply provides one. A flash with nothing behind it is the empty flash, a readable state of its own: the beacon flashes on the cadence, no bodies come, and the forecast shows the next slot. The flash is a signal event and needs no power: a dark beacon still flashes at its dispatch and is dark again after it, so a crowd that entered under it retargets or spreads. The Collector's gates decide supply (Districts, the Collector). Only the panel selects intake; powering a beacon by any other means, including a coil, lights it but never makes it flash. Every district tables its panel: position, powered branch, intake selected, beacon that flashes (Campaign, section 3).
-
- **After entry, in one order (R1).** Every body resolves the first line that applies: 0, stunned (inside the eight-second stun, and it conducts); 1, pursuit (the surveyor is within its pursuit range: chase, and drift back when out of range); 2, a role target other than light (the Floater's is the flow while water flows; the Anchor's the lowest wet ground; the Carrier's the nearest reachable loose charge within its acquisition range; the Grounder's the nearest reachable powered run); 3, attraction (walk continuously to the nearest lit beacon it can reach; hold on arrival; never leave a held beacon for a farther one; retarget to a nearer reachable lit beacon when its own goes dark); 4, spread (no lit beacon reachable: press outward along the entry branch). Pursuit outranks attraction, which is why harvesting inside a held crowd costs health; role targets sit below pursuit and above attraction, so up close every body is just a body. (Owner: Combat Rules.)

- **Pursuit range** is about ten metres, a channel's width, and each district names a landmark for it. A body outside it does not chase; a crowd does not cross a district to reach the surveyor. The first battery in any written expedition is therefore earned at a crowd's edge, inside that range, and priced in hits (REV104-8). Contact costs one health with a moment of immunity after; the surveyor has five.
- **Press (R2).** A crowd holding at a beacon occupies a radius set by its size; when bodies join, the radius grows over a few seconds, and when bodies leave or die it shrinks. Press is that relaxation seen from outside, not an unbounded creep. A crowd with no beacon has no centre and spreads along its branch, which is the dangerous case. The forecast overlay draws one ring per crowd. The pumping district's tuning bound becomes checkable: the merged crowd after the third dispatch must not reach the causeway head before the evacuation window closes.
- **What is a beacon.** The district's dispatch beacons, the portable beacon (armed and charged, carried or planted), and a moving beacon where a district adds one (the Tram Incline's lamp, a lure that never flashes). Every other lamp is an indicator.
@@ 52,7 54,7 @@
- A Carrier that reaches a mote on the ground takes it and carries it; killing that Carrier drops it again (R5). Nothing but the surveyor and a Carrier can take a mote.
- **A coil discharge** needs a full linked battery and spends it. It energises the water the surveyor is touching for two seconds and stuns every conducting body in that water for eight (R3, ruled at r3 and confirmed: Equipment countersigned at Coil r2 and Equipment r2; Combat's effect table still carries eight seconds of powered water and is to be brought to this row, PMR006 1). An uninsulated discharge costs two health; after the two seconds the surveyor can collect inside the water without insulation. Stunned bodies that have already shed yield nothing; stunning again buys control, not charge.
- **The arc** drains a full linked battery over about ten seconds, one burst per battery; a body hit while the burst runs is chained and the hit conducts onward to at most three further bodies within a short reach, body to body, needing proximity and line of sight; the chain does not travel through energised water and the arc never energises water (R10 declined; the bounded model preserves spatial limits and is recorded as the alternative's counterpart). The burst returns no motes from bodies that have shed. Starting a burst reserves its battery until it ends; an interrupted burst discards the unused fuel. The Glossary's "about twenty seconds" is wrong; ten is the number.
-
- **A Spark killed in water** energises that water for two seconds, the same window as a discharge, and by the intensity rule it stuns nothing and damages no organism; it hurts an uninsulated surveyor standing in that water and it makes no chain (PMR006 2, chosen as Combat wrote it; r3's stun clause is withdrawn). Its own kill mote is the yield, if it had not shed.

Its own kill mote is the yield, if it had not shed.
- Charge never leaves a district with the player; charge left in a battery at extraction is lost at the dock. What a district's own machines meter or move is that district's design.

**PM report.** Task: the Lead's reconciliation of PMR006's five blockers as they fall on the contract, and of REV104 r2's four contract notes; artifact: this page r4 (r3 59f895 and earlier in history). Changed decisions: none canonical; one r3 clause withdrawn (the Spark's stun) in favour of Combat's row; the persistence rule and the intensity rule added; the refuge's cascade position stated and the pump reserve declined. Evidence: written design against the cited revisions; no player data; nothing built. Risks: the ten-metre pursuit range is a proposal every written scene now leans on; the cascade cadence is a guess; Combat's table still carries eight seconds until countersigned. Next handoff: Combat to countersign the two-second window and the Spark row in its effect table; Colony to mirror section 6's persistence rule and the cascade; World to carry "a grounded run recovers between expeditions" in its table; the critic on this revision with the Campaign's r3; PM's next review.

Evidence: written design against the cited revisions; no player data; nothing built. Risks: Stop's image, dark boards and trickles, is the campaign's last picture and is now the one both World and this page state; the two-second window and the fixed-power row are countersigned by Equipment and, for the window, by Combat.
