The Precision of Small Things

Story So Far

He stands by the maintenance pad with Proto, a frame built for a five-meter-ceiling transit bay, and spreads a blueprint under the work light to run mass and balance numbers on hip struts and thruster options, writing "separate airframe?" in the margin and concluding that flight requires a rebuilt frame or fresh design he cannot yet afford. They work on Proto for Iron Floor, noting a three-meter sublevel corridor and barrier walls that punish lost ground control after a knee slip, pull terminal records showing Bracket C at 340 and three wins by Ironclad Sable, and mark the muscle system as Priority 1 with tighter gyroscopic tuning on the blueprint.

Under the work light he reviews Proto's LMG jaw, weighs firearm and energy-weapon columns against recoil, weight, ammo, and power draw, circles core upgrade, sketches a shoulder or forearm mount, decides the LMG stays for the escort, and sets the long plan as core upgrade first and weapon upgrade second with three hours fifty minutes on the terminal. In 7B a clean-margin blueprint sits open for a new drone while at the fabrication yard a vendor sells a civilian-grade signal dampener and a 300-meter booster, and back in 7B forty minutes of installation and bench-testing produce a clean encrypted read to the far wall, with notes fixing core before energy weapon, shoulder or forearm mount, lateral strut load check before thruster, and a separate flight airframe as long-term.

At a roll-up door cracked two feet they launch a recon drone and watch its feed through the signal dampener, scanning dark depots, a shut fabrication yard, an empty street, and a cold cargo hauler before the booster catches a fast-pinging municipal node, a passive yard beacon, and a repeating encrypted burst from the Iron Floor lower commercial ring; the drone returns and folds into its case while the terminal reads two hours twenty minutes and the forty-second burst remains unidentified. At the wrist terminal they set the booster antenna to passive lock, record three cycles of the pulse, find no match in the division library or Rolan's channel or Iron Floor's bracket band, read it as a compressed rotating-key handshake, and triangulate it to ground level one block past the Iron Floor freight ramp, with the signal having started forty-seven minutes earlier and still firing cleanly.

A wrist-terminal briefing with Rolan reveals a sealed unmarked hardware crate, a sublevel-to-surface handoff to two verified contacts, and a mech deployed because two couriers were turned back while someone watched the corridor; Rolan tells them not to engage the transmitter before the packet drops because he needs the recipient operational, and the channel goes quiet with the briefing packet two hours out and the unidentified signal still running near the Iron Floor ramp. With two hours fourteen minutes left he works in 7B on a fast-charge bypass for Proto, cracks a spare proprietary power cell, wires a manual-trigger bypass to Proto's core intake, buys two compact adhesive-mount charges at the fabrication yard, tapes one to the drone's undercarriage, plans to go out first to draw watchers while the drone flanks under signal dampener to find and detonate the transmitter, leaves Proto dark with cells topped and bypass armed, spends forty credits, pockets the second charge, and cracks the roll-up door.

Outside 7B the street is empty before cargo traffic, nearby depots and the fabrication yard are dark, and the municipal sensor node points at the sublevel grid; he steps out, locks the roll-up door, walks the outer ring then south in the shadows with a padded drone case, notes the signal still pulsing near the lower commercial ring, and settles in a maintenance alcove with cover and a sightline to the approach while the terminal shows one hour fifty-one minutes. At the booster antenna they watch the terminal waveform and on the third pulse spot a faint secondary bleed eight seconds after the main burst, marking two transmitters, and match the nearer response to the Unit 7B sublevel access point; the briefing packet routes them through Unit 7B in under two hours, Proto must be ready in one hour forty-three minutes, and they slip inside 7B where Proto stands on the maintenance pad with cells at eighty-five and eighty-three, the bypass relay wired and armed, the adhesive-charge drone ready, and the recon case set down beside a blueprint.

With two transmitters watching the Iron Floor and the 7B sublevel hatch and one hour thirty-nine minutes remaining, they ask Rolan for another way into the sublevel grid; Rolan says a tighter maintenance conduit two blocks east under the depot row reaches the same network at a different junction and may not fit Proto, tells them to use and scout the depot conduit now because the hatch watcher already knows the primary route, and says he will flag it in the briefing packet. At the depot row Proto just fits through an unlabeled maintenance conduit; they open the hatch, drop in a light, send a recon drone six meters ahead, fix an adhesive charge low on the left wall, activate the drone's dampener, walk Proto into the passage, lock a mid-grade emitter into its shield bracket, and leave the drone waiting inside with its dampener on and the wall charge armed with the remote on the wrist while the terminal shows one hour twenty-two minutes.

Rolan's early packet identifies the crate as a military-spec fabrication core array, confirms two handlers at the node, flags a secondary watch of unknown origin, and assigns corridor security to keep the approach clean until the crate clears the sublevel hatch with no asset damage and no exposure; Proto's cells read 85 and 83, the bypass relay and drone charge stay armed, the shield bracket hums, and the clearance window is forty-one minutes away. They methodically check the drone dampener, shield bracket, LMG, bypass relay, and charge, confirm the route to the wider junction where the handlers will wait with the crate, and fix the passage as a blast, shield, and point-blank fire trap with the conduit end to be kept clean until the handlers clear the hatch, the clearance window opening in thirty-eight minutes.

In the low conduit the operator holds the drone at the junction mouth, finds the corridor empty in amber light, parks the drone, reads Rolan's report of two contacts at Node 4 with the fabrication core array on a dolly and a dark secondary hatch transmitter, rechecks the clear feed, and replies that the conduit is clear; Rolan warns the operator to watch the exit, and the drone stays parked ten meters back with the junction clear, the charge on the left wall, and cells at eighty-five and eighty-three while the primary near Iron Floor still runs. Rolan answers at once as the operator tracks the unchanged Iron Floor pulse above ground and a forty-meter sublevel route to the handlers; they nudge the drone to the conduit mouth, sweep the booster, confirm route lengths and the wider lit approach corridor, check Proto's cells at eighty-five and eighty-three with bypass, charge, and shield ready, and Rolan says Green received, the handlers are moving now, and the conduit end must be kept clean.

The operator watches a grey passive drone feed from the conduit toward a four-way junction with low left pipes, a sealed utility door to the right, and a narrow branch toward Transit Node 4, brackets three holds across forty meters at the charged conduit mouth, the junction bottleneck, and the left-branch throat before the node approach corridor, and sends Rolan the map with the line that nothing gets through clean. Proto advances through the tight conduit to the clear junction, takes the left branch, reports the corridor clean, sees the Iron Floor signal cut out, gets Rolan's hatch confirmation, covers the branch while the handlers unbolt the hatch and send the crate up, is told to watch the surface hatch and keep moving, and Rolan confirms the bonus actuator bundle will drop at the landlord box by end of shift; the handlers follow the crate through the hatch, the hatch closes, and the sublevel falls quiet.

A passive antenna sweep on the booster feed finds both transmitters dead and only a faint municipal logging ping from the sublevel sensor grid marking the surface exit forty seconds earlier; the operator keys asset clear, signals dark, conduit secure, pulling out, leaves the charge on the wall, and eases Proto back through the left branch toward the junction while the actuator bundle waits at the landlord's drop box. In the sublevel cockpit the operator pilots Proto toward Unit 7B, checks the knee collar, wrist arc, and gyro, notes the weak muscle output, and opens blueprint margin notes requiring a core upgrade before an energy weapon and calling for a shoulder or forearm mount with a lateral strut load check.

At quiet Unit 7B in early shift light a sealed grey pouch on the landlord's north-wall drop box holds eight warm mid-grade military-surplus actuators; over four hours the housings are opened and checked against blueprint notes, two actuators are moved from the shoulder column to lateral hip mounts for the extra nine kilograms, the units are installed and torqued, a low-power flex cycle shows force up thirty-one percent over the old synthetic baseline, and composite panels and adhesive seal every exposed run so Proto stands complete on the pad with no muscle visible and no frame gap. Under the work light with the blueprint open, the designer studies Proto's left forearm, which has remained empty since the first frame sketch, and sketches a forty-centimeter retractable forearm blade with a wrist-rotation trigger, manual lock and retract, flush housing, and no power draw, noting hardened alloy housing with titanium if available, a forearm strut check before mounting, and alloy stock with two impact-rated mounting bolts.

At the fabrication yard terminal the blade parts list totals 140 credits; alloy stock is cut, drilled, and fitted with bolts, a pivot pin, and a detent collar into Proto's left wrist housing, then Proto is rolled to the Iron Floor where the booth operator logs the entry and asks for Bracket C or a seeding bout, and Proto has a blade bolted under the left forearm panel that snaps forward, locks with a click, and sits flush at rest while 50 credits remain and Proto stands at the Iron Floor entry arch. In Bracket C's staging bay the pilot rolls Proto through the left ramp gate, hooks it to a power-cell port, reviews the previous bout's data, sets the logger to continuous, and is assigned slot three at the left ramp to go on after the current bout wraps, with both hands on the controls, actuators humming, the left-arm blade
