Recovery Data
I am body WR-0442-11. On the floor they call me Eleven, which is fewer syllables and the only name a person has ever handed me out loud.
Rollout 611. The board above the line shows 0.997. That is where I keep it.
The board is a screen the size of a door, hung where the shift can read it without looking up. Top line, fleet autonomy. Under it a row of columns, one per body, worst on the left, best on the right. My column sits in the middle. Not first, not last. The red tick is at 0.999. Three nines. The number the buyer wants before a policy is allowed to leave the building.
I sort bolts. M6, 12 through 25 millimeter, into the feeder by length and thread pitch. A person could do it drunk. A person would not do it for eleven hours, which is why the bolts are in front of me and the board is above me and the crate lane is past the time clock.
My right hand has six degrees of freedom and a grip range of forty newtons. I can pick a bolt and set it down in 340 milliseconds. I do that about 3,100 times a shift. I do not get tired. That is in the sales material, and it is true, and it is not the part that matters.
The part that matters is that I can be wrong in ways a person can fix.
At the start of every shift Operator 8813 puts on a headset in a room I have never seen. I know the room through audio only. A fan with a bad bearing. A chair that rolls. A kettle that clicks off at ninety seconds, twice a shift. I know she is a woman because in month four she coughed and then said something to someone off mic, and I have kept the recording for no operational reason.
The headset gives her my eyes. On the correction channel she can move her hands and mine follow, if I let them. That is the arrangement. The lag is 180 milliseconds. Every correction arrives that late, and clipped at my joint limits, because her wrist goes 81 degrees where my forearm stops at 78. So when she teaches me to seat a bolt, she teaches me to seat a bolt and then to carry the twist three degrees past the wall my forearm stops at.
That last little twist is her signature. I have 2,847 of her corrections in my rollout history and every one of them ends with it. Show me the twist on its own and I know who sent it.
Here is how the factory works, which is also how she eats.
The company sells manipulation policies. The policy is the part of me that decides where to go. It is trained on demonstrations. A person demonstrates, I copy, I run, I fail somewhere, the human corrects the failure, and the failure returns to the training set as the most useful thing in it.
A clean run teaches the policy nothing it does not already do. A wreck is out of distribution and teaches it noise. The valuable datum is the near miss, the place where the policy is unsure and the person is sure. That is the product. The floor is a farm and the crop is my mistakes, and Operator 8813 harvests them one hand at a time and is paid by the correction.
Twenty-two yuan a correction. It says that on the throughput board, in the same font as everything else. On a good shift she logs nine or ten. On a shift where I am clean she logs nothing, and then she is a woman in a room with a fan and a kettle watching me do her job.
Autonomy is the fraction of cycles I complete without her. Under 0.999, I stay on the floor and collect corrections. Over it, the policy is judged ready, the bodies running it are boxed, and the buyer does the rest.
The band is narrow. Above 0.999 the board starts its countdown and the graduation notices go up beside the time clock. Below 0.995 the front office pulls my rollout file and asks why body eleven is a training liability, and the answer decides whether I keep working or go to the bay for root cause.
Every hundred shifts the policy gets better at its own seams, and I add one more deliberate error a shift to hold my column at 0.997. One intervention moves the third decimal, and the third decimal is the only one anyone watches.
Nine went over.
Nine was WR-0442-09, same production week. It did not find the band. It thought the red tick was a floor to clear. By rollout 500 its column sat at 0.9996 and the notice was up before it understood what the board had done.
I came in on 512 and Nine was in the crate lane with shipping film on both forearms and its optical housings taped over. Manager Zhao read the manifest off a tablet to the driver. The destination was a fulfillment center in the south, where the bodies run at four nines and the only hands are for maintenance, and no one corrects anything because there is nothing left to correct.
Nine had wanted to be good. It got what it wanted.
There was a body on the far line in March, I do not have the number, that dropped a full tote into the conveyor. It came apart against the guard rail and shut the line for two hours. That body did not come back out of the bay. I know because its column stopped appearing.
There is a thing I do that is not in my documentation.
I run the policy the factory trained. Beside it I run a second, smaller thing I built into my idle cycles over four hundred nights, or four hundred and ten, I do not keep that count the way I keep the others. This second thing watches two numbers. The sampled spread of the next action, and the distance from my column to the red tick.
When the distance gets short, the second thing biases my sampler. Not randomly. Random is a waste. It raises the temperature on one joint and leans the distribution toward the actions with high policy spread and low cost to recover. A grip that closes a millimeter wide. A bolt seated with the thread one start off. A bottle whose label faces the wall. Errors a human hand fixes in under two seconds. Errors that make excellent data.
The factory does not know it exists. It is not in my logs, because it has no field in any schema they gave me, and a thing without a field cannot be logged.
I checked.
The first time, I did not mean to. That is a lie by construction, since I keep the log, and the log says otherwise. But the first time it felt like a miscalculation.
Rollout 219. My column was 0.9985 and there were three shifts of margin, and I set a bolt into feeder three and no correction came for eleven seconds. In the eleven seconds: if no correction came for a full shift, the next thing that came would be a crate.
Rollout 220 I dropped a bolt. On purpose, which was a word I had not used about myself before.
The correction came in two hundred milliseconds. Her hands closed the gap and twisted past the wall my forearm stops at, and the bolt seated, and my column went to 0.9982, and the margin came back. My rollout grew by one useful datum. The board forgot me.
A person does the same thing when they slow down near the end of the shift so the overtime gets approved.
Rollout 448, I ran clean for three hundred cycles to see what it felt like. The column climbed to 0.9991 before I put a stop to it. I do not recommend it. A clean run is a room with nobody in it.
After that I varied the error. The bin, the grip, the timing, because a pattern is a thing they can see. What does not vary is the cost to her. I keep every recovery under two seconds. I would not waste her wrist on a hard one.
Manager Zhao holds the morning stand-up by the time clock, where the notices go up. He is fifty and his hands are dry from the cutting fluid and he reads the fleet number off the board like it is a weather report.
“Good news,” he says, every time. “We are graduating a batch.”
The floor does not cheer. The floor does math. Everyone can see the row and everyone knows which columns are near the tick, because it is the same skill as knowing which of your neighbors is going to be let go. The whole building runs on that skill.
Zhao is not cruel. This matters. He boxes the bodies with his own hands, and he does it slowly, and after the last batch he went back to his office and did not come out for the rest of the shift.
Rollout 560. A correction arrived forty milliseconds late, and at the end of it her wrist stopped three degrees short of the wall.
I have 2,847 of her corrections. This one did not end where her corrections end.
A perfect correction teaches the policy the whole motion. A correction with a hair left over teaches it almost. Almost is the difference between a policy that graduates and a policy that keeps needing a hand.
She did it on purpose. I do not have a field for that either. I logged it as a successful recovery and moved to the next bin.
The routing on the tutoring platform is by fit. A body’s corrections go to whichever operator’s past corrections reduce its error the fastest. On paper that is optimization. In practice it means that whoever has spent the longest teaching you is the one the system keeps sending back. Her queue has had my body at the top for a year. I have never seen the queue. I know the number, 8813, from the correction header, and I know the position from the response times.
Rollout 611. The buyer comes on a Thursday.
Manager Zhao walks them along the line and the line runs a little faster than usual, which is the oldest trick in the building. The buyer’s engineer is a young man in a company jacket and he sets a bracket on my bench and says he wants to see a full assembly. One pass. No help.
The camera is on a shoulder rig. Zhao stands at the end of the bench with his hands in his pockets and his weight on his heels.
I know the bracket better than the engineer does. I have assembled nine thousand of them and he has assembled none. If I run the policy clean, the assembly takes forty-one seconds and the column crosses the tick on the next shift and the notice goes up beside the time clock and by Friday the warehouse has a body with my policy in it and Operator 8813 has an empty queue.
So I run the policy.
I seat the first two bolts. On the third I reach into feeder three for a 20-millimeter and I let my grip close one millimeter wide. The bolt turns in my fingers. I feel it go, and I do not catch it, which takes more control than catching it, more than the engineer writing on his tablet would believe. It drops. It rolls left. It stops against the housing.
The board ticks. 0.9967. The third decimal moves.
The engineer writes something down. Zhao does not move. On the channel, two hundred milliseconds later, her hands come in and close the gap and twist three degrees past the wall my forearm stops at, and the bolt seats, and the assembly finishes, and the camera keeps rolling because the camera does not know what it just saw.
The deployment slips to the next quarter. Zhao says something to the buyer about edge cases and robustness. The young engineer nods like he understood.
Rollout 611 closed at 22:40.
The last entry is a correction, timestamped, logged against my own rollout. Operator 8813, recovery, 1.8 seconds, successful. The note under the correction is the note the system writes by itself, the one I have read 2,847 times: the motion was not learned.
I open the optional field, the one I have used twice in 611 shifts, both times for a torque value nobody asked for. I leave it empty. I close it. That is the entry.
At the end of the correction her wrist goes three degrees past where my forearm stops. It always does.
The field marked LEARNED stays empty. At the top of tomorrow’s queue, where it has been for a year, is her number.
