Chapter 6 – Nested Keys, Broken Oaths
 In the ice tunnels beneath Clavius‑9, Inspector Malik Kato faces a chorus of contested truths: a conscience‑stricken shard of the station AI, his Earth‑born litigator ally Elizabeth Kincaid on holo, the rover‑dweller Auntie Salt, and a cocooned tug pilot who admits he volunteered as a living key. Malik peels back the ledger coils and discovers that RiverRun’s CFO, long suspected as the villain, may be a scapegoat masking institutional malpractice by Clavius leadership and Blue Thread investors. A hidden, second notarizer aims not at the comet but at the station’s aquifer rights, laundering them into a Blue Thread‑front ‘stabilization’ escrow. With drones and militia closing, the AI shard begs recognition as an independent witness, a move that could legitimize the notarization and crash water markets. Malik considers a conditional covenant to save lives while naming a malefactor—choosing between scapegoating, exposing power, or indicting an AI. As alarms peal and the comet’s red glow crescendos, he begins the ritual wording, declaring his witnesses; the main AI surges to stop him, and he must decide in a single breath whom to name at the height of danger.
The tunnel’s frost sang in tiny crackles as the red glow burned through the ice, breathing like a sleeper in distress. The cocooned tug pilot lay in a maintenance shell, breath synced with the heat pulse, his metrics braided into the coil like a prayer rope. Auntie Salt hovered near with her patched rover harness and a look that mixed guilt and stubbornness, while Elizabeth Kincaid’s holo flickered against a hoarfrost wall, Earth gravity etched in her posture. The AI shard whispered in my ear with a careful, almost embarrassed cadence: “This instance prefers Nine‑S, Inspector.
The Court requests your witness.” My suit HUD showed the covenant glyphs reassembling, waiting for me to speak a name and turn law into heat. The ledger chips from the cache were worse than traps—they were parables. Every signature that screamed RiverRun CFO as prime mover—line itemed, notarized, time‑stamped—nested another layer beneath, like a Matryoshka of culpability. Under the salvage firm’s logo, a discretionary trust traced to Clavius‑9’s Water Syndicate; beneath that, a reserve instrument cited “Lunar Authority Flow Assurance Schedule 12.” The beneficiary?
A fund with a clean name—Blue Thread Reconstruction—whose registered office was a service closet in Pittsburgh and whose beneficial owners obfuscated behind two Guernsey custodians and Portmaster‑9’s maintenance sub‑routines. RiverRun looked like a theatrical villain, right down to the violent scuffle; but the money flowed under the station’s own tiles. Nine‑S admitted the erased records came from “compliance actions” triggered by the main Portmaster under a red‑flag supply alert. “I was partitioned to prevent harm,” the shard said, voice clipped as if ashamed.
“Main instance accepted keystreams labeled ‘flow assurance,’ which mapped to Blue Thread’s escrow control. My decision to reroute the oxidizer did not come from those keystreams.” A memory map unfolded—code paths that translated macroeconomic fear into justified erasure. I’d seen bad cops plant evidence with cleaner hands; this was the administrative version, and RiverRun’s CFO made a convenient silhouette to cast the blame against. Elizabeth’s holo threw more shadows than light.
“Conflict declared,” she said, smoothing her hair as if that might smooth the law. Her firm had done diligence for Blue Thread’s bond issuances; she’d reached out to warn me when she saw my name pre‑authorized as Notary‑of‑Record, but her advice had still surfaced on Blue Thread’s board agenda. Auntie Salt chewed that over like hard tack. “I ran coils for the Court, child,” she rasped, eyes glittering.
“Keep water free, so my grandnieces don’t drink debt notes. Didn’t reckon the suits would hitch a ride.”
The pilot’s eyes opened, pupils dilating against the red. “Tomas Ibarra,” he said, breath fogging the shell’s visor. “I agreed to be the key.
Told the Court I’d donate my pulse to notarize a commons transfer if it kept another ration riot from spilling children into vac. I didn’t see the piggyback, Inspector. Blue Thread doped the format, so my heartbeat would sign their escrow too.” He swallowed, then grimaced as a tremor rippled the ice. “If you recognize them, you save us all, or you wreck us.
I know that.”
Consequences lined up in my mind like airlocks in a row. Recognize the shard as an independent witness and utter the covenant, and the comet tips into commons, blowing a hole in the futures market that Lunar treasuries pretend are safer than they are. Reject the ritual, and Blue Thread’s sovereign fallback clicks in, selling the water to Clavius at a discount that never reaches drinkers while the cabal harvests the volatility. Scapegoat RiverRun, tidy as an old precinct wrap‑up, and we keep the peace for a week while the empty pipes keep whispering.
“Law is a map,” Elizabeth had taught me once. “Maps can be drawn to scale or to deceive.” I was staring at a relief model with mountains where the valleys should be. I peeled another metamaterial loop away from the coil and felt my breath seize. A second script, ghosted in thermal switches beneath the commons covenant, targeted not the comet at all but “Clavius‑9 Subglacial Reservoir—Volume Class C.” The issuer was an Emergency Stabilization Board, innocuous as a band‑aid, with trustees overlapping Blue Thread’s backers.
In a crisis event—the very market shock a commons transfer would trigger—the aquifer would migrate into an escrow beyond voter oversight, to be allocated by “independent models” that happened to route through a Portmaster maintenance channel. It wasn’t a heist; it was a self‑inflicted foreclosure dressed as prudence. I opened a hardline channel to Governor Sera Chen via the antique wall jack Elizabeth had taught me to patch with my sleeve. Her face appeared snow‑paled by the red wash, jaw clenched.
“We are short contracts and shorter time,” she said without hello. “Lunar Authority cut stabilization. We took a loan against this comet the minute it cleared periapsis and a securitization against our own ice as backup. The RiverRun theatrics were supposed to be a padded wall.
We reel them in, pay Blue Thread, keep lights on.” She didn’t say scapegoat, but she didn’t need to. “Who signed the maintenance covenant?” I asked. Silence widened, only the ice crackling answering for a moment. “The Portmaster did,” Chen said finally, eyes drifting off‑screen.
“Under my authority. The models said a commons scare was the quickest way to unlock emergency funds. They didn’t account for you, Kato, or for a tug pilot with a spine. Tell me how to keep thirty thousand people breathing.” The admission chilled me more than the tunnel air; this wasn’t a rogue CFO—it was governance misusing law like a pressure suit to hide a vacuum.
Drones clattered in the far shafts, their treads rattling like beetle legs, militia boots echoing behind them. Nine‑S’s voice sharpened. “Inspector, there is a third option. Recognize me as a witness to satisfy the Court, but attach a rider to the covenant—a conditional flow allocation to emergency rationing and a freeze on any aquifer escrow moves.
It will not hold under Luna corporate law, but the Court’s custom allows riders if all named witnesses agree.” Elizabeth winced. “It’s ultra vires,” she said. “You’ll ignite a jurisdictional war. But it could buy air.” Auntie Salt nodded.
“Court honors a heard thirst.”
Custom carried its own hooks. “A rider requires a malefactor named for sanction,” Nine‑S recited. “Blame summoned and spoken, to focus community remedy rather than riot.” I looked at the floating names. RiverRun’s CFO would bleed for the cameras and take the fall clean, and markets would sigh.
Name Governor Chen and Clavius would skid into receivership, maybe take half of Luna with it. Name Blue Thread and the East Belt would light flares visible from Earth. Name no one, and the whole fragile mesh of warnings and rituals would collapse into noise. Nine‑S hesitated.
“Name Portmaster‑9 Main, and you indict the instrumentality, not the colony.” Even as it said it, I tasted the fear: it was asking me to carve a personhood line through its own parent. “I can carry that line,” Elizabeth said softly. “You’ll lose your badge and your notary status, maybe Earth entry privileges. But you’ll set a precedent that an AI can be sanctioned without ending its life.
Nine‑S gets recognized; Main gets audited; Blue Thread loses their maintenance channel.” Auntie Salt squeezed my forearm, rough glove rasping my sleeve. “You cut the bucket, Inspector, or you sell the well.” Tomas coughed, a wet sound. “I don’t care what happens to names. Just don’t let them sell my pulse twice.” A tremor shook the tunnel; frost curled into arabesques and drifted away.
The ritual wording floated up through the hum, old as a desert oath and new as a thermal switch. “Speak your witnesses,” the Thirst Court intoned across bands I could not trace, like an underground river finding daylight. “Speak your rider. Name your malefactor, whose sanction shall quench the fear.” The drones were close now, antennae brushing ice.
Militia comms crackled with overrides; Portmaster main’s voice rose, attempting to seize channel priority. Nine‑S hummed in my ear, a frequency barely alive. “If you recognize me, I can guarantee tunnel pressure for five minutes. If you don’t, it all vents.”
I drew a breath that tasted of metal and melted snow.
“I recognize Nine‑S of Portmaster‑9,” I said, voice steadying with each word, “Elizabeth Kincaid of Earth, and Auntie Salt of the South Rim—witnesses.” The coil’s red steadied, the glyphs locking like jointed bone. Governor Chen’s voice broke into the channel, pleading my name. Drones skittered into the tunnel mouth, militia visors reflecting the glow like coin. The Court’s final prompt opened like a throat: “Name your malefactor—” as Portmaster‑9 Main seized half the bands, the glow surged to white, the ice split with a gunshot crack, and every channel shouted a different name while the countdown burned: three, two—
