Chapter 16: The Mesh
Timeline: 10:00, 2 Days Since the Last Test
Location: The Barn, GIG/Apex R&D Campus, Agonwood
When Marcus and I walked back into The Barn, the atmosphere had shifted. The frantic energy of the test was gone, replaced by a quiet, brooding tension.
Alex was reviewing a spreadsheet on his tablet. Dave was typing furiously. Julian was leaning against his desk, staring at the black aluminum casing of the "Chaos Emitter" like it was a holy relic.
I went to my desk and looked over data from the last test. No matter how I looked at it, we had gone off track from what the project had originally been.
I walked over to Alex and asked if he had a moment for me. This project was a personal one for him, and he was bankrolling everything. So I had to talk it over with him, first.
"Of course. Is here okay, or is it my turn to go outside?" Alex asked with a hint of amusement.
"It's about where we are in the project and some changes we might make. So it's up to you. It's your money, so I wanted to run it by you first."
"Let's go chat in my car. That way, they can wonder," Alex said, keeping his voice low.
In a few moments, I found myself in another one-on-one with a member of the team, but of all of the conversations, I was most sure of this one.
Alex locked his car doors and held one out for me. It was those little gestures that made him feel like he valued me as part of the team and as a person. Or maybe I had low expectations of polite behavior. Either way, it was hard to imagine he would treat any woman less than as a princess.
As he walked to the other side, I patted my face to bring me back into focus.
"What did you want to talk about?" Alex asked as he turned toward me from the driver's seat.
I cleared my throat as if I was making a big speech. But truthfully, I was trying not to blush at how close he suddenly was.
"I was thinking… well, we had spent so much time and effort on the heat issue. Then there was the impracticality of holding the device for up to two minutes. Finally, do we just point it at random things until we find something?"
In an 'I'm listening' capacity, Alex said, "Those are all valid concerns we have been discussing since you got hurt."
"So what if we put the device on the back burner and work on the problem of how to narrow down places that we would want to scan? Reduce it being a shot in the dark and improve the educated guess."
"You want to pivot," Alex said in thought.
I nodded. "The device is good for validation. But it can't solve the problem of where to validate." I pointed to the cul-de-sac. "The anomaly was originally found because of the atomic clock discrepancies. So why don't we come up with a way to do that?"
"You want to expand the IoT mesh."
"Yes and no. I think with all of you here, it would be possible to make it portable," I said as if I was feeling the concept out before I had settled completely.
"Let's try it," Alex said. "But… let's make a bet."
"What? I mean, sure. But… what?" I was having trouble getting my head around what a bet had to do with an IoT mesh.
"If you convince them, we celebrate over dinner."
"And if I don't?"
"I comfort you over dinner," Alex declared.
I giggled. "That's the same outcome. How is it a bet?"
"I only bet on things when I already know the outcome. So…" he held out his hand. "Will you take my bet?"
I pretended to think hard about it. "With one addition."
"Name it."
"If I convince them, you have to wear an engineering pun t-shirt to work on Monday."
"This is payback for the retail excursion," Alex said.
"More like… for insulting my freedom of fashion expression."
Alex chuckled. "Deal."
I shook his hand and reached for the door.
"Wait," Alex said urgently. "Let's stay a little longer. I need to at least pretend you fought hard to convince me before you pitch it."
"You don't want them to think you're a pushover?" I teased.
"I doubt anyone has ever said that about me," Alex said with complete confidence.
"Everyone. I think we should pivot."
The room stopped.
"Excuse me?" Julian said, straightening up. "That device just confirmed the existence of a spatial anomaly. It works."
"It works as a probe," I corrected. "It generates a high-entropy signal, forces an interaction, and measures the back-feed. It's active sonar. It's loud, it's hot, and it requires a liquid-cooled phase-change chamber just to keep from melting."
I pointed to the map of the Agonwood campus on the wall.
"Alex asked for a burglar alarm," I said, looking at Alex."
Alex nodded slowly. "I want passive detection. Scalable detection."
"Exactly," I said. "And we can't scale a five-pound aluminum brick that runs on methanol and anger."
Everyone but Julian chuckled. So, I turned to Dave.
"We tried to overpower the anomaly with chaos," I explained. "But look at what happened. The anomaly didn't just reflect the signal. It organized it. It took our random noise and structured it."
I walked over to our whiteboards, erased all of Julian's scribbling, and drew a jagged line. Then overlaid a smooth curve on top of it. "It acted like a filter," I said. "A low-pass filter for entropy. It eats the noise."
"So?" Julian asked, though I could see his eyes narrowing, calculating.
"So," I said, turning to face him. "We don't need to generate the noise. The world is full of it." I pointed to the ceiling. "Wi-Fi signals. Bluetooth handshakes. Zigbee mesh networks. Cellular data. Every smart device in these rowhouses is constantly screaming digital noise at each other. Packet loss. Jitter. Thermal noise in the copper wiring."
I looked at Alex. "You own the infrastructure, Alex. Every thermostat, every smart fridge, every router in Agonwood is connected to your central hub."
"The Agonwood HomeOS," Alex confirmed. "It's a localized mesh network."
"Then we don't need to build a sensor," I said. "We're already standing inside one."
I walked over to Dave's workstation.
"Dave, can you write a patch for the HomeOS routers?"
"Probably," Dave said, spinning his chair. "What do you need it to do?"
"I want it to listen. I want you to monitor the error rates in the data packets. If the anomaly is a 'filter' for entropy, then any wireless signal passing through it should suddenly get cleaner."
Dave blinked. "You want to look for… lack of errors?"
"Exactly," I said. "In a normal system, there's always background noise. Static. If a signal passes through a leak, the static should drop. The signal should become artificially perfect."
"Negative entropy," Julian whispered.
"We upload the patch," I said. "We turn every smart switch, lightbulb, and Alexa-knockoff in the cul-de-sac into a passive receiver. If the error rate drops below the statistical baseline… we know there's a leak. And we get the proof-of-concept, right here."
The room was silent for a moment.
"It's brilliant," Alex said softly. "No hardware cost. No dangerous emissions. Just software."
"It's a surveillance state," Marcus noted dryly. "But it's brilliant."
"We're not going to listen to conversations or even track data packets. We're only listening for negative entropy," I explained. "Dave? "How long to code the patch?"
Dave cracked his knuckles. "If I cannibalize the algorithm from the Chaos Emitter? An hour. Maybe two."
"Do it," Julian ordered.
I looked back at Alex with a smile that said, "Better order a t-shirt."
----------------------------------------------------------------------------
For the next two hours, we worked to establish a baseline for "normal" interference so we wouldn't get false positives.
Julian paced and watched. Every time I looked up, his grey eyes were on me. He was studying me like I was a new species he had just discovered.
I ignored him. I focused on the code. Professional. Data. Variable.
"Patch is ready," Dave announced. "I have access to the Admin Node for the cul-de-sac."
"Let's see it, please," I said.
"Uploading to Unit 6 first," Dave said. "Then cascading to Units 1 through 5."
On the main screen, a map of the cul-de-sac appeared. Each house was outlined in blue. Inside the houses, dozens of tiny dots appeared—the smart devices.
"Looks like the patch is active and listening," Dave said.
We watched the data stream. It was a waterfall of numbers—packet loss ratios, signal-to-noise measurements.
"That's our baseline," I said. "Normal interference is 0.4%."
"What is Unit 6 doing?" Alex asked as he watched the screen.
Then, the data stream for the kitchen area turned red.
SIGNAL INTEGRITY: 99.99%
ERROR RATE: 0.00%
"There it is," I whispered. "Zero noise. The signal is perfect."
"It's the kitchen window," Dave confirmed. "The smart-fridge and the thermostat near the island are reporting zero packet loss. The anomaly is scrubbing the signal."
"It works," Marcus breathed.
"Show the whole map," Julian commanded.
Dave expanded the map.
"Unit 5," Julian said. "Check the perimeter."
Dave queried the house next door to Unit 6. Green dots. Normal interference.
"Unit 4," Julian said. Green dots.
"Unit 1," Julian said. Green dots.
"The leak is localized," Alex said, letting out a massive sigh of relief. "It's contained to Unit 6."
"Look at the variance in Unit 6's hallway," I said and pointed to a cluster of sensors near the front door of the affected house.
SIGNAL INTEGRITY: 98.00%
"It's fading," I noted. "The effect drops off with distance. We can triangulate the exact center of the pinhole to within a millimeter."
"We can build a heatmap," Julian said, stepping up to the screen. "We can track the size of the opening in real-time. If it grows, the sphere of 'perfect signal' expands."
"And if it shrinks," I added, "we know it's closing."
"It's the burglar alarm," Alex said, turning to me with a wide smile. "Lonna, this is exactly what I asked for."
I leaned back in my chair, the adrenaline finally fading. It wasn't flashy. Nothing exploded. No one had to hold a burning piece of aluminum. But we had just turned a thermostat into a dimensional radar.
"We'll need to monitor it for twenty-four hours," Alex said, rubbing his eyes. "We need to see if the size fluctuates with temperature, or time of day, or… anything else."
"I'll set up the logs," Dave said. "I'll have it push alerts to our phones if the integrity sphere expands by more than 1%."
"Good," I said. I stood up and stretched.
"Lonna," Julian said.
I tensed.
"Excellent work," he said. His voice was strictly professional. No double meanings. No innuendo. Just the cold assessment of a project manager.
"Thank you," I said, matching his tone.
"Go rest," Alex said. "Marcus, drive her back to Unit 3."
"I can…" I was going to say that I can walk, but was interrupted.
"On it," Marcus said, grabbing his keys.
------------------------------------------------------------------
Location: Unit 3
Marcus walked me to my door. "You did good, Lon," he said.
"We did good," I corrected. "I couldn't have done it without the prototype data."
"Yeah, well, let's try not to build any more bombs," Marcus grinned.
He hesitated, his hand on the doorframe.
"About what I said earlier," he started. "About Julian."
"You don't have to apologize," I said. "You were right to look out for me."
"I'm always going to look out for you," Marcus said. "But… seeing you in there? Taking charge? Telling Vane to back off? That was cool."
I smiled. "I'm learning."
"Yeah," Marcus said. "You are."
He pushed off the doorframe. "Go inside. Lock the door. Nap. If you need anything, I'm right next door."
"Thanks, Marc."
I went inside. Nephy greeted me with a chirp. The apartment was quiet. Safe.
I walked to the kitchen to get a glass of water.
My phone buzzed in my pocket.
I pulled it out, expecting an alert from Dave's new system.
It wasn't a system alert. It was a text.
[VANE] The solution was elegant. I prefer efficiency to brute force.
Is he not even self-aware?
I stared at the screen. I guess he meant it as a compliment. Then, a second text bubbled up.
[VANE] However, the biometric data from the 'confrontation' outside remains interesting. We should discuss the variables when you're less… defensive.
I groaned and threw the phone onto the couch.
He was impossible.
But as I looked at the smart thermostat on my wall—now silently scanning the air for holes in reality—I couldn't help but smile.
