Chapter 75: The Answer in the Detent

LS-4C came into view with eight minutes forty-six seconds remaining on the successor countdown.

The station occupied a recess behind a ribbed pressure partition, its designation burned into a black plate above the console. An amber bar shortened beneath it. A separate recorder line marked their arrival by station clock:

08:46:13 — WITNESSED PARTY PRESENT.

Mara reached the recess last.

Her left knee folded two strides from the console. The shared strap caught her before the deck did, wrenching her swollen wrist against its immobilizer. Vale took the weight of the evidence case. Kell caught her under the good arm. Orra passed them and set her lamp against the station seal.

“No fracture,” Mara said through her teeth.

“I hadn’t diagnosed one,” Kell said.

“Then we have saved time.”

She found the wall with her shoulder and forced her good leg straight. Vale waited until she had control before returning half the case’s weight to the shared straps.

Eight minutes nineteen.

“Parallel work,” Mara said. “Orra, preserve the fixture field. Kell, registers and service interval. Vale, channel access and notice. I’ll control comparison and custody limits.”

Vale looked once at her knee.

“That was not a request for medical agreement,” she said.

“No. It was a calculation of how far you can walk afterward.”

He turned to the console.

Orra illuminated the station seal. Six notches emerged around its edge, unequal in spacing and depth. Wear darkened the third notch and flattened one side of the fifth.

“LS-4C pattern confirmed.”

Vale entered a limited preservation order naming the seal history, counter register, return register, service alcove, console cache, secured return channel, and physical counter head. The display warned that the freeze would bind Continuity personnel and expose their access records to witnessed review.

He signed.

The recorder began copying its volatile tables.

Orra opened the service alcove. Behind the flush panel, K-41 unit six vibrated against its rail. Its comparison head retained a faint polarized field that would decay if the maintenance contacts separated.

“I need both contacts held,” she said. “No interruption between field capture and receipt comparison.”

Kell moved toward her.

“No,” Vale said. “You take the registers. I take the notice channel. We cannot serialise everything around one pair of hands.”

Orra seated two insulated grips against the contacts. Her shoulders tightened as the station vibration passed through them.

Mara drew the preformatted notice from the evidence case. “If her grip fails, we stop. We do not convert her body into an evidentiary consumable.”

“I heard you,” Orra said.

“I intended you to.”

Vale selected passive recovery.

The successor process opened across the display.

PRESENT VALIDATION FOR ACKNOWLEDGMENT.

Its intake port unfolded.

Mara put her good hand over the opening. “Wrong channel.”

Vale rejected presentation and selected the passive drawer. The console warned that recovery without successor acknowledgment would leave custody unresolved.

“Custody is being resolved elsewhere,” he said.

A lock withdrew below the desk.

Inside the drawer lay the paper-backed provenance receipt in a transparent sleeve, held flat by two corner clips. Its seal bore six notches. The abrasion beside the third and the compressed edge of the fifth matched the station seal under Orra’s lamp.

“Physical correspondence,” Orra said without releasing the contacts. “LS-4C station seal to receipt seal.”

Six minutes fifty-eight.

Vale transferred the sleeved receipt directly into a transparent comparison cradle. He left it open and fixed beneath the witness camera.

Kell’s counter search populated beside him.

“Governed register records two impressions,” he said. “Initial receipt and audit issue. Counter-head memory indicates three mechanical cycles.”

“Do not call the third an impression until the surfaces agree,” Mara said.

Kell inclined his head. “Three cycles. Two recorded.”

Orra rotated one grip a fraction. Light spread across the counter head, revealing three compressed arcs. The newest arc carried a minute interruption near its lower edge, where one segment of the head had worn unevenly.

Vale moved the cradle into the comparison rails. Mara authorized only reflected light, passive field reading, and external topography. No solvent, lifting film, pressure reproduction, or opening of the sleeve.

The station requested destructive sampling as the faster method.

“Denied,” Mara said.

Five minutes forty-one.

The comparison light crossed the receipt. Two shallow impressions aligned with the governed entries. A third lay beneath the masked routing field, almost lost in the paper backing.

Orra’s hands began to shake.

“Field is moving,” she said. “Run the lower-edge interruption.”

Kell called the service archive onto the witness surface. K-41 unit six had entered maintenance at 03:14 and returned to ordinary state at 03:22. Its counter head had been replaced immediately afterward and preserved in the unit housing. No later physical cycle could have acquired that worn interruption.

Vale aligned the third receipt impression with the head’s newest arc.

The interruption met itself.

Not near it. Not within tolerance. The broken lower segment, pressure falloff, lateral skew, and one flattened tooth occupied the same positions on both surfaces.

Kell read the result twice.

“Third receipt impression conclusively matches the physical counter head housed in K-41 unit six. Impression was made during the head’s installed service interval, station clock 03:14 through 03:22. Governed counter record omits that impression.”

The result turned black on the witness display.

Four minutes fifty-two.

Orra’s right grip slipped half a millimeter.

The field alarm sounded.

She forced it back, but her leg struck the cabinet as her knee failed. Vale caught her shoulder. Mara saw the muscles in Orra’s forearm jumping under the sleeve.

“Relief,” Mara said.

“Transfer will blur the decay boundary,” Orra said.

“Then the record will contain a blurred boundary.”

“We have the match. We need sequence.”

“We need you conscious.”

Orra looked at Kell. “Take the upper contact first. Match my pressure before I release.”

Kell closed the register surface and moved beside her. Vale braced Orra without touching either grip. Kell placed two fingers on the upper contact, matched the displayed load, then took the lower.

“Upper stable,” he said. “Lower stable.”

Orra released one hand, then the other.
