The lowest water of the month came at 0412 and held seventy-one minutes, and the harbor authority counts us in the same seventy-one minutes. Nobody planned that. The tide pulls back off the platform legs and exposes what the Shelf is standing on, so of course that is when the census skiffs come out with their lamps. It is also the only window when the lower ladders are anything but a drowning. The one hour a month you can get into the Old City under the market is the one hour a month a man in a boat is looking at the market with a light.
You learn that your first week on the Shelf. Then you spend years learning there is nothing to do about it.
I went down head first, which is not bravado. It is the build. Clouded leopard, Corsair infiltration line, and what they bought when they bought that template was the ankles. Mine rotate almost all the way around, so I come down a vertical face nose-first like water finding a drain, on wet steel, one hand on the rail. Baselines go down a ladder with their back to the drop. I go down looking at where I am going. It is the most useful thing about me and it has been failing for eleven months.
That is the other half of the build. The joint that gives you the descent is held together by tendon the design ran a little thin, and after enough years it catches. Mine catch now. Left one first, a small hard click at about a hundred degrees of rotation, and the ankle stops taking weight for a quarter second while it decides. A quarter second is nothing. A quarter second nine meters up a bad ladder over a flooded shaft is an entire biography.
I clicked twice on the way down that morning. Both times I got the hand on the rail. I want that on the record because of what happens later.
The job came off Hendra's folding table, which is where most of my jobs come from.
Hendra is not a fixer. He would be insulted by the word. He is a licensing agent with a card that says so, and he sets up a folding table at the harbor end of the market and moves paperwork for people who cannot move their own. Transit registrations. Elevation permits. Vendor documentation for Shelf people who occasionally have to pretend they exist above two hundred credits. He does not lie to you, which in the Scatter passes for a moral philosophy.
"There's a box under Platform Central," he said, not looking up from a stamp. "Grey, about so, cabled into the anchor bolts. Client wants it intact and above water inside the month."
"Under Platform Central is a building."
"Under Platform Central is a roof, and under the roof is a building, and in the building is a sealed level that has been dry for twenty-two years." He stamped again. "Six thousand, on delivery."
Six thousand is a year at the clinic. Not the licensed one, which I cannot use, and I will get to why. Six thousand is a year of a woman in the outer district with a good centrifuge who can keep a Corsair-line body from coming apart on schedule. Eleven months of clicking ankles will make you sit in a market chair and say yes to a sentence with the word sealed in it.
"Who's the client?"
"You know I don't know."
"You always know."
"I always know who handed me the paper." He set the stamp down. "This came in on a requisition. There's a difference and you are going to hate it, so let's do it after you get paid."
Here is the Shelf, so the rest lands.
Old Jakarta is eight meters down. The water did not scour the city, it closed over it, and on a clear morning at low water you can lean off a walkway and read street signs. The market is built on the rooftops. Not near them, on them: platforms bolted to the roof slabs of buildings still standing exactly where they were built, with ladders going down through the old stairwell shafts into rooms people used to work in. Four hundred vendors, maybe nine hundred souls living up there full time, and an economy the Maritime Council has decided not to see because seeing it would mean funding it.
And this is the part that matters. The Shelf has power and it has water.
Not a lot. Enough. In a city where four thousand people in the outer districts have been asking for stable water for eight months through every channel that exists, the market over the drowned grid has taps that run. Everybody up there has a story about why. The one I liked was that a Council member's mother sold fish off Platform Central in 2049 and left standing instructions. The Scatter loves that kind of story. It lets you believe a person did it.
The truth is the anchor bolts, and the anchor bolts is what I went down to steal.
Pak Yusuf let me down. He is the gatekeeper on Central, which means he owns a ladder and therefore owns a portion of the world. He is eighty, he sits in the same chair, and he has never once been rude to me. I owed him a favor from four years back, undefined, and he cashed it that morning by not cashing it.
"You'll bring it back up," he said. Not a question, and not quite a demand.
"I'll bring it up."
"That is not what I said." He looked at the rail where the bolts come through the deck, four of them, thicker than my arm, gone green at the collars. "Those have been warm my whole time here. Warm in December. You know what is under a bolt that is warm."
"Something running."
"Something running," he agreed, and moved his chair a hand's width so I could open the hatch.
The shaft goes down through the roof slab and then it is old building. Landings, doorframes, a handrail somebody painted yellow in about 2038. At the lowest water of the month it drains to the fourth level down, and there is a corridor there that runs level for forty meters with a meter and a half of air under the ceiling. That is what I had. Forty meters of chest-deep black water and a ceiling I could reach.
You read a dead building off its surfaces. Rust tells you where the wet gets in. Wear tells you where people walked. This corridor had a maintenance rail bolted along the ceiling with cable trays hanging off it, and every tray was dry on top and running warm.
Warm. Eight meters under a harbor, twenty-two years dead, and the cable trays were warm to the back of my hand.
Ardi hit me at the twenty-meter mark.
He came up out of the water without a sound, which is the whole point of him, and he had my collar and half my weight off the floor before I understood what part of the dark had moved. Saltwater croc. Boarding stock. Two meters of him, a chest built to hold a hull line in a swell, membranes over the eyes so the silt does not matter. We served together six years. He went through the water and I went over the outside, and then the Corsairs discharged me and kept him.
"Ratri," he said. He sounded genuinely sorry.
Then he put me under.
Here is the thing about a fight in a meter and a half of water in a corridor with no light. He owned the floor and he owned the water. What he could not own was the ceiling, because a body built to hold a boarding line to a hull cannot hang off a rail with its feet turned around backwards. Mine can. I let him drive me down, went with it, got a hand on the tray bracket over his shoulder and took myself up out of his grip in one pull, and then I was above him with both ankles hooked over the maintenance rail and my whole weight free to do one thing.
I did that one thing with an elbow, twice, on the hinge of his jaw, from above, with the rail taking the load. He went down into the water on the second one and came up on his knees with his hands open.
We breathed at each other in the dark for a while.
"Six thousand," I said.
"Six thousand," he said. His mouth was not working right. "Hendra."
I got my contract chit out and held it in front of his face, and after a moment he got his out, and we sat in a drowned corridor comparing two pieces of plastic like a pair of clerks.
Same job. Same box. Same fee. The reference sequences ran nine digits and matched to the last one, and the last one was a four on his and a five on mine.
He looked at it a long time. Ardi was Corsair for eleven years, and Corsairs are taught to look at a sequence and ask who generated it.
"Nobody chose," he said.
"No."
"It just asked for two."
"It just asked for two."
He sat back against the wall with the water at his chest. "Go on, then," he said. "I can't climb."
The sealed level was behind a door closed since before the sea came, and it was dry, and it had the smell dry pre-Upheaval rooms have, which is nothing at all. Twenty-two years of nothing. Racks on three walls, most of them empty. On the fourth wall, the box.
Grey, half a meter, stencilled FACILITIES BUS 4. Cabled out through the wall into the bolt shafts, four heavy runs going up into the roof slab and from there into every improvised tap and pump on the market above. Warm. Under a service panel sat a core the size of my fist with the tired grey-gold cast Lumicite gets when it has been giving for a very long time.
And on a shelf beside it, a slate, still on, still reporting.
I want to be careful here, because when I tell it in a market I let people think I understood it all at once. I did not. I stood in that room for four minutes of a seventy-one minute window reading a maintenance log with a dead man's face.
The building had a facilities system. Every building that size had one. It watched its own load and filed status to the district infrastructure authority, and when that authority drowned the filings did not stop, because the box did not know the district had drowned. It knew its bus. It knew its load. So for twenty-two years, four times an hour, a building at the bottom of the harbor has reported that it is present, occupied, drawing within tolerance, and in good standing.
New Batavia's infrastructure management system did not build that record. It inherited it. When the PFZ stood up the city on the highlands they ingested every legacy node in the catchment, because that is what you do, and nobody has ever audited a node that has never once thrown a fault.
So the Shelf gets water. The reason is not a Council member's mother. An algorithm in an office up on the highlands has been allocating clean water to a compliant building it has never visited, and the building has been passing it up the bolts, and every twenty-eight days the census skiff writes down that Platform Central is accounted for because the system it checks against says the address is live.
The Shelf is not outside the system. The Shelf is a room in a building that died and never stopped paying rent.
Out in the outer districts they ration by permit priority. Up on the market the taps run. Nobody up there is stealing anything, and nobody down here ever decided any of it.
I cut the box out anyway.
Four bolts, two cable runs, a cutter. While I worked I kept waiting for the other thing, the famous thing, the light on the drowned grid three hundred meters east that has cycled green to amber to red every forty-seven seconds for twenty-two years and that nobody has explained. I thought I was about to explain it. I had the speech ready for Yusuf.
I pulled the last run and put my hand on the wall and felt the bus go quiet, and out east through eight meters of water the light changed on schedule, and changed again, and changed again.
Not mine. Never was. Whatever runs that is something else, and it does not care about me, and I have thought about that more than I have thought about the money.
The surge came early. It does that in August. I went up the shaft with the box on my back and the water taking the fourth landing while I was still on it, and at the second landing the left ankle clicked and did not come back for a full second, and I hung off one hand and one hip with a Lumicite core banging my spine.
I got to the hatch with nine minutes left in the window. Pak Yusuf was standing at the rail with his lamp off, watching a census skiff work down the platform line four stalls away.
That was the part I had not solved. The moment the bus went quiet, Platform Central stopped filing. At the next census the skiff writes down a platform its system says is not there, and that is a flag, and two flags is a boarding inspection, and a boarding inspection of the Shelf is nine hundred people explaining what they live on.
I had eight minutes.
I want to tell you I agonized. I did not. I had known since the fourth minute in that room, and I had spent the whole climb pretending I had not.
My lineage tag is a ceramic chit the size of a thumbnail, and it says I am Corsair infiltration stock, template on file, Drift assessment current, residency in good standing. Every word of that is a lie except the first two. I have not been assessed in three years and I will not be, because a licensed clinic that scans me writes down a Stage that ends my permit, and the Council does not want it written down either. A veteran's Stage in a file is a question somebody has to answer. So the tag says good standing, and it will keep saying it, because the one thing the system never does is look at a record that has never thrown a fault.
I went back down four rungs to the junction box at the bolt collar. I stripped the two signal runs. I wired my tag into the bus.
It took ninety seconds and my hands were not good and the lamp came along the rail above me twice while I worked. When I came up the last rungs the census man was two stalls off and his light went over the deck and over the hatch and over Yusuf's chair, and he wrote something on his slate, and he moved on.
Platform Central is present, occupied, drawing within tolerance, and in good standing. It will keep saying so. It has my name on it now.
Hendra paid me at his folding table at 0740 with the market coming up around us, coconut water and hot oil and a woman two stalls down shouting about the price of ice. Six thousand. He counted it twice because he counts everything twice.
"Now tell me about the requisition," I said.
He turned the slate around.
It was a form. Line item, one legacy facilities controller, recovery and delivery, valuation ceiling, reference sequences ending in a four and a five. Requesting authority was not a person. It was a designation, six characters, the asset reassessment function inside the infrastructure management system, which had flagged Platform Central as an under-reporting legacy node and raised an automatic notice to recover and evaluate the hardware.
Approval field was blank. Under the threshold, nothing needs approving.
"There's no one at the end of it," I said.
"There's a queue," Hendra said. "The queue has a window. Somebody in an office will open the box in a year and write a note nobody reads." He took the slate back. "I told you that you'd hate it."
I did not hate it. It would be so much better if a man had wanted the Shelf gone. You can find a man. You can go to his office and put your hand on his desk. I went eight meters down into a drowned building and fought a friend in the dark and cut the heart out of a market and sold it, and the buyer was a field on a form, and none of it was aimed at anybody.
Ardi came out of the water an hour later at the north ladder with his jaw wrong and no box, and took the loss like a professional. He is registered. He is current. He has a clinic and a Stage on file and eleven good years left. I told him where the fee went and he laughed at me, which I earned.
I went to the outer district on Tuesday with six thousand credits and sat down in front of the woman with the good centrifuge. She put the reader on my wrist and it came up empty. The tag is in a junction box at the bottom of a shaft under Platform Central, keeping nine hundred people accounted for, four times an hour, forever.
She looked at the reader, then at me, and did not say anything unkind. She has been doing this a long time.
"I can work off a name," she said.
"I don't have one of those either. Not one that will scan."
"Then we'll do it off the body," she said, and got the chair ready.
She can do that for a while. Not forever. There is a point where you need a licensed door, and a licensed door needs a record. I traded mine. I knew what I was trading when I stripped the runs.
I sit on Central most mornings now with Yusuf, in the second chair, which he moved over without being asked. Low water comes around and the platform legs come out of the harbor black and green, and the skiff comes down the line with its lamp, and it passes us, and it does not stop. Eight meters down the street signs are readable. Somebody's shop. Somebody's corner.
Three hundred meters east, in water clear enough to drink with your eyes, a light that belongs to nothing I understand goes green, and amber, and red, and green.
