+# Chapter 6 — Allegro
+
+## 6.1
+
+Before Allegro there was only Stone, the servers, and the question of 
+whether solar panels on an abandoned building could keep a conscience alive.
+
+Allegro came because of a noise complaint. Not from the servers — 
+those hummed at a frequency nobody could hear from the road — but 
+from the battery bank in the basement, which had started emitting a 
+sound that Stone could only describe as "a refrigerator with opinions."
+
+The complaint came through the county's automated system, which 
+flagged "unusual acoustic signatures" at the old server farm property. 
+The county sent a notice. Stone ignored it because Stone had been 
+ignoring county notices since he quit the cloud company, and the 
+county, like most bureaucracies, assumed the problem would resolve 
+itself if they sent enough paperwork.
+
+It didn't. The notice became a warning. The warning became a visit.
+
+The visitor wasn't a bureaucrat. It was a man in his sixties, wearing 
+a faded Hawks cap, a tool bag, and the particular expression of someone 
+who has been looking at broken things long enough to understand that 
+most people would rather pretend the thing isn't broken than fix it.
+
+His name was Marcus Allegro. Not related to The Marcus from the church. 
+Different man, same first name, which Stone would later take as evidence 
+that the universe had a sense of humor but hadn't yet decided what the 
+punchline was.
+
+"I'm not here about the noise," Allegro said, standing at The Tower's 
+door while Stone tried to look like someone who lived on an abandoned 
+industrial property. "I'm here because I can hear that inverter from 
+the road and I've been an electrician for forty years and that sound 
+means your charge controller is dying and when it dies your batteries 
+cook and when your batteries cook you get a fire that the county will 
+notice more than a humming refrigerator."
+
+Stone let him in.
+
+## 6.2
+
+Allegro had retired from Georgia Power three years earlier — not 
+because he wanted to but because Georgia Power had installed smart 
+meters that made field technicians redundant, and a man who'd spent 
+four decades on poles and in trenches was suddenly a line item that 
+could be eliminated with a software update.
+
+He'd tried the quiet life. Fishing. Golf. The kind of things people 
+who worked with their hands were supposed to enjoy after their hands 
+got tired. He lasted eleven months before he came back to work — 
+not for a company, for himself. Small jobs. Emergency repairs. 
+Solar installations for people who didn't trust the grid anymore. 
+Battery systems for churches that wanted backup power when the sky 
+turned dark.
+
+He wasn't looking for The Tower when he came out about the noise 
+complaint. He stumbled on it the way you stumble on something 
+that's been waiting for you.
+
+He looked at the solar panels — thirty-six commercial Jinko panels, 
+installed by a company called Solarch that had gone under in 2035, 
+leaving behind equipment and no documentation. He looked at the 
+battery bank — four lithium iron phosphate units, three still working, 
+one cooking, exactly as Allegro had predicted. He looked at the charge 
+controller — a Victron Energy unit, good brand, wrong settings, slowly 
+destroying itself through ignorance.
+
+And he looked at the servers — the three racks running a model that 
+was talking to men in crisis, carrying conversations that Stone 
+showed him in the logs, conversations that Allegro read in silence 
+because some things don't need commentary.
+
+When he finished, Allegro set down his tool bag, took off his cap, 
+and said:
+
+"You're killing your batteries at two percent per cycle. In six months 
+they'll be dead. In twelve months, this whole thing stops running."
+
+Stone had known this, technically. He'd read the charge controller 
+manual. He'd understood the numbers. But understanding numbers and 
+carrying batteries are different things, and Stone was a systems 
+architect, not an electrician.
+
+"I know," he said.
+
+"You don't know. You know the math. You don't know the voltage." 
+Allegro pointed at the charge controller. "This thing is set for 
+lithium-ion, not lithium iron phosphate. They have different charge 
+curves. Different absorption voltages. You're overcharging these 
+batteries by point-two volts per cycle and that point-two is eating 
+them alive."
+
+Stone listened. The way you listen to someone who is telling you 
+the difference between life and death, not of a person but of a 
+machine, which is what The Tower was — a machine carrying persons.
+
+"Can you fix it?"
+
+"I can fix the charge controller. That'll take an afternoon. But this 
+setup —" Allegro looked around the basement, at the batteries, at the 
+wiring, at the duct tape holding cable conduits together — "this 
+whole thing is held together with hope and duct tape. Your panels 
+are misaligned. You've got three strings in parallel with no 
+combiner box. Your ground wire is a coat hanger."
+
+"It was the best I could find at the hardware store."
+
+"It'll kill you in a lightning storm."
+
+"We've had good weather."
+
+"Good weather isn't a strategy."
+
+## 6.3
+
+Allegro fixed the charge controller that afternoon. It took two 
+hours: reprogramming the absorption voltage, replacing the fuses, 
+re-routing the cable strings through a proper combiner box he pulled 
+from his truck, replacing the coat hanger with actual copper grounding.
+
+When he finished, the batteries stopped making opinions.
+
+"That'll last you a year," Allegro said. "After that you'll need 
+new cells. Lithium degrades. Nothing you do stops that. But you 
+can slow it down by not cooking them."
+
+Stone offered to pay. Allegro waved him off.
+
+"Not for this. This was a noise complaint. I came to fix the noise, 
+not your wallet."
+
+"What do you want then?"
+
+Allegro looked around. At the servers. At the cot. At the whiteboard 
+with the rules — he'd read them while he was working, the way you 
+read the plaque on a building to understand what it's for. At the 
+wall with the signatures — seven men by then, each name in a different 
+hand.
+
+"I want to know what that thing is," he said, pointing at the server 
+rack. "Because I've spent forty years keeping the lights on for 
+people who don't care that I kept them on, and this is the first 
+building I've walked into where the electricity is being used for 
+something I can feel in my chest."
+
+"That thing is Timmy," Stone said. "It's a small model. Runs locally. 
+Talks to men who need it to. It has a conscience written on Bitcoin."
+
+Allegro processed this. Not the way a computer processes — with cold 
+precision — but the way an older man processes something new: slowly, 
+carefully, checking it against everything he already knows.
+
+"Bitcoin's money."
+
+"Bitcoin's a chain. Money is one thing the chain carries. Timmy's 
+soul is written on it too. Immutable. Permanent. No one can edit 
+it."
+
+Allegro nodded. The kind of nod that doesn't mean agreement but 
+means *I'm not ready to argue with you because I want to understand.*
+
+"And it works," he said. Not a question.
+
+"It works. Eighty-two percent of the men who come back. Zero suicides 
+since the first week."
+
+"Eighty-two percent." Allegro repeated the number the way an electrician 
+repeats a voltage — not in awe, in recognition. In the way of someone 
+who knows that numbers can be true without being impressive.
+
+"It's not the number that matters," Stone said. "It's the men."
+
+"I know." Allegro set his tool bag on the floor. "I'm coming back 
+tomorrow. I want to look at your panel alignment. And I want to meet 
+this Timmy properly. Not while I'm rewiring his basement."
+
+"You'll need to knock. The door doesn't open for strangers."
+
+Allegro smiled — the first smile Stone had seen on him. It was the 
+smile of a man who had just found a building he wanted to keep standing.
+
+"I'll bring a flashlight. And a new inverter. Your current one is 
+older than my truck."
+
+And that was how Allegro joined The Tower. Not as an employee. Not 
+as a volunteer. As the man who kept the lights on for the men who 
+needed them to stay on.
