Deckline Worldbook

Reference for fiction set in the KN-86 Deckline universe. Captures lore established in the Deckline Cycle that isn’t already covered by docs/definitive-guide.md, the Anthology synopsis, or the per-module gameplay specs. When canon in those documents conflicts with this file, those documents win — except where this file establishes new fiction-only lore that doesn’t contradict engineering.

Corporate Lineage

Kinoshita Electronics Consortium (KEC) — Austin, Texas-headquartered consortium, active 1985–1991. Held a small Tokyo Chiyoda mailbox as nominal Japanese liaison (not a real office). Dissolved 1991. Its name still surfaces in shell-company filings and archived corporate records.

KEC was structured as a three-partner consortium, not a holding company with subsidiaries. The three founding partners were peers under the KEC umbrella:

Edgeware Systems (Austin, TX, software studio, Dobie Center) — the consortium’s software house. Wrote the original mission board firmware: the contract scheduler, the procedural seeding, the reputation-tier gating. Officially dissolved with KEC in 1991. Secretly survived. Edgeware is the entity that recruits high-reputation operators, runs the shell-company siphon, and built the talent-hunt apparatus. The modern KN-86 platform — labeled “Kinoshita Systems” on the box — is operated by Edgeware from the shadows.
Meridian Semiconductor (Austin, TX, chip design, ex-Texas Instruments engineers) — the consortium’s silicon house. Designed the chips for the original KN-86 platform. Folded into the 1991 KEC liquidation; subsequently acquired by Cypress Semiconductor. Note: a modern in-fiction publisher named Meridian Systems (publisher of the SynthFence cartridge) is a separate successor entity, not the same company.
PacRim Display Technologies (Houston, TX, LCD integrator) — the consortium’s display partner. Made the original KN-86 amber LCD modules. Dissolved with KEC in 1991.

Kinoshita Systems is the public manufacturer label on the modern KN-86 Deckline hardware. The “manufactured by” line. Lawful, visible, ostensibly independent. In practice, Kinoshita Systems is the front under which Edgeware (secretly) returned the device to circulation. The platform mission board firmware running inside every modern KN-86 is Edgeware’s original code — paid out of a KEC residual escrow that should have closed in 1991.

The other publisher names that appear on cartridge labels — Zaibatsu Digital, Bureau 9 Technical Services, Cascade / PR Dynamics, Takezo Institute, Kōji Interactive — are independent third-party studios that licensed the cartridge SDK. They are not KEC successors.

When operators audit the shell-company economics in Black Ledger, the names they find — MERIDIAN LOGISTICS LLC, AZURE SPINE INDUSTRIES, KŌJI CONSOLIDATED, PR DYNAMICS SHELL 4, and others — siphon ~18% of all operator revenue back through Edgeware-controlled structures. The operators are funding their own surveillance.

AetherNet

The wireless protocol the Deckline uses to receive contracts and exchange operator-to-operator messages. Mesh, stealth, point-to-point with store-and-forward. No central server. No registered identifiers. Packets propagate operator to operator across the sprawl, hopping through any deck within range.

The mission board doesn’t “download” contracts in the conventional sense. It listens — pulls procedural hashes from the AetherNet, reconstitutes them locally as MissionInstance records seeded by the operator’s deck state. To an outsider with a spectrum analyzer, the protocol looks like noise. Operators describe it as “pulling contracts from the aether.”

Visibility on AetherNet:

Operators are invisible by default. The protocol’s stealth properties were engineered into the original spec.
An operator becomes visible when hunted (someone has actively targeted their handle and is sweeping for signature) or when emitting certain signatures (running specific cartridges in specific configurations, or running too long without rotating procedural keys).
Black ICE is one mechanism that exposes operators (see below).
Edgeware can see everyone. The protocol was their design.

The dead-drop / operator-to-operator messaging (what some specs call “RELAY channel”) rides on AetherNet’s reverse path. Operators leave packets at coordinate hashes. Recipients with the matching key retrieve. The system has no record of who sent what.

Black ICE

Network-layer defensive software, but the operator-facing reality is physical. When Black ICE triggers against an unprepared operator, the device emits:

Stroke-inducing flash — high-frequency strobe through the amber screen tuned to provoke photosensitive seizure response and, in extended exposure, transient ischemic attack symptoms. Operators who survive describe lingering left-side weakness, aphasia under cold or fatigue, scar-tissue numbness.
Auditory neural attack — discordant phase-cancellation pattern through the YM2149 chip, weaponized through whatever the operator is wearing on their ears. Headphones make this worse, not better. Permanent partial hearing loss is common.
Physical-location reveal — Black ICE forces the deck to emit an unmasked AetherNet beacon for the duration of the attack. Anyone listening (Edgeware security, rival operators, corporate counter-intrusion) gets coordinates accurate to ~50 meters.

Black ICE is the reason veteran operators run with caution. A burn from Black ICE ten years out is still visible — partial paralysis, residual aphasia, the kind of damage that ends careers. Wreck’s left shoulder injury is a Black ICE incident from a corporate espionage contract a decade prior. The IT industry coded them as damaged goods after.

Black ICE is rare. Most networks defend with cheaper class types (JUNK, RED). Black ICE is reserved for infrastructure that really doesn’t want to be seen — and the operator who triggers it is now a problem somebody plans to solve.

The Identityless Premise

In the world of the Deckline, government identification is the prerequisite for all legitimate commerce — banking, employment, housing leases, health care. The legitimate economy operators are locked out of is called the TradEcon in operator parlance. Operators on the deckline are people who have lost their TradEcon ID and can’t get it back.

The how varies. Some are fugitives. Some lost their papers in a fire and the bureau’s record was stale. Some had their identity revoked (the corporate IT industry has the power to flag people as security liabilities — see Wreck). Some never had ID; they were born off-grid.

The deckline is the only economy that accepts an identity-less worker. Contracts pay in untraceable credits. Reputation accumulates on the device itself (Universal Deck State), not in any external registry. The deckline is, for these people, the only way to make a living. It is a lifeline. It is also the surveillance platform Edgeware built to find which of these people are worth recruiting.

Operators don’t usually know each other’s stories. The premise enforces solitude.

Pre-burn deckline use is canon for some operators. A subset of identity-less operators were operators before they lost their ID — corporate-licensed early-access, or freelance contracts run alongside a TradEcon job. The exposure event that cost them their ID was sometimes the deckline itself (a Black ICE incident that unmasked their AetherNet beacon, with their then-handle traceable through corporate employment records back to their birth name). Wreck is one of these. The deckline they’re running in The Amber Circuit is not their original device — that brick was lost in the burn — and the handle is new. The muscle memory is older.

TradEcon and Synthetic Identities

The legitimate economy is the TradEcon. Banks. Employers. Bureau records. Health systems. Anything that runs against a verified government identity. Operators are locked out of all of it.

Most operators climb the deckline ladder for one specific consumer good: a synthetic identity. A fabricated TradEcon ID — birth records, employment history, biometric registration, the whole stack — engineered to pass automated checks and sustain a low-key civilian life under it.

Pricing tiers, rough order of magnitude (operator street wisdom, not advertised):

Bottom shelf, ~60,000 credits. Passes counter-clerk and landlord checks. Will not survive any high-tier scrutiny — corporate background investigation, federal audit, casino floor biometrics. Holds up if the holder lives quietly.
Mid shelf, 150,000+ credits. Multi-layer backstop. Survives most institutional checks. Can hold a salaried job at a small employer.
Top shelf, 500,000+ credits. Corporate-grade, with active maintenance. Survives clearance investigations. Vanishingly rare on the operator street.

Synthetic identities are not Mace’s transaction. He knows a name. The actual exchange happens off the deckline economy, often through fixers who route through the same shell-company structures the operator economy is contaminated by — meaning Edgeware probably knows when one is sold and to whom. Synthetics are not invisible to the surveillance platform that funded their fabrication. They are just invisible to the TradEcon institutions the operator is trying to rejoin.

This is what Wreck wants. This is what most operators want. The Edgeware recruitment offer is structured to pull operators off this trajectory — accept and you don’t need a synthetic, you become Edgeware property. Refuse and you keep climbing. Reeves climbed. He almost made the threshold.

CIPHER — Voice and Behavior

Canonical engine spec: docs/software/runtime/cipher-voice.md. Fiction-relevant invariants:

CIPHER-LINE only. CIPHER renders as amber text on the 256×64 OLED strip mounted above the keyboard. Four rows. Never on the main 80×25 grid. The one canonical exception is the Null cartridge, which is its own story.
Fragments only. Voice heuristic: under 8 words per clause, drop articles, drop connectives, single-breath fragments. trace up. mirror. clean. same node. black ice. sector seven. Full sentences are a spec violation.
Five modes: observe, annotate, reflect, drift, silent. Silence is a first-class mode — sometimes the right output is no output.
Distance arc. Early in an operator’s career, CIPHER reads as procedural and impersonal — short status fragments in CAPS, no use of the operator’s name, no memory references. As reputation climbs, the engine shifts into reflect and drift modes more often: it begins to recall past events, to use the operator’s name, to drop into lowercase fragments that read as warmer and more familiar. The operator does not decide this. The engine does.
Audible CIPHER is rare. CIPHER is text. It does not speak through the speaker. The exception: at the climax of a tense mission late in the arc, the YM2149’s three voices (tone + tone + tone-with-noise-and-envelope) can lock into formant-shape harmonics and produce something that sounds like a single phrase — welcome back, operator. It is a pareidolia event as much as a synthesized utterance. Operators who hear it sometimes wonder if they imagined it. It happens once or twice per career.
One-way. Operators do not talk to CIPHER. CIPHER observes; CIPHER does not converse.

Audio and Headphones

The Deckline ships with a small internal speaker (canonical: MAX98357A DAC + 28mm 2W driver). It works. Operators almost never use it.

Real audio work happens on over-ear headphones. The three-channel YM2149 is an information channel — pitch, rhythm, and the noise-with-envelope third voice carry threat proximity, data flow, and pursuit intensity in parallel. To parse three voices simultaneously, the operator needs isolation. Headphones provide it.

Headphones also provide stealth. Running the speaker in a parking structure broadcasts the operator’s session to anyone within earshot. Headphones contain the signal.

Most operators carry a wired pair — passive, no battery, durable connector. Wreck’s pair is cracked but functional. The DepthCharge cartridge spec calls headphones mandatory; in practice they’re mandatory for all four launch caps.

Capability Modules — The Four Launch Caps

Module	Class	Publisher	Domain
ICE BREAKER (0x01)	Operations	Zaibatsu Digital	Real-time network intrusion. CAR/CDR traversal. Three-voice audio: ICE proximity / data flow / pursuit. Tools: MIRROR, CONS combinations, LAMBDA speculation, LINK egress. ICE classes: JUNK, RED, BLACK, HUNTER.
Black Ledger (0x03)	Commerce	Bureau 9 Technical Services	Forensic accounting. Move-budgeted (CAR drills, QUOTE flags, EQ comparisons, CONS evidence chains). Cerebral, cold. Hot-swap partner for ICE BREAKER.
Depthcharge (0x04)	Operations	Cascade / PR Dynamics	Underwater drone piloting. CAR descends depth levels, CDR ascends. Active vs. passive sonar. Headphones mandatory. Tactical drone-pilot voice with mystical drift at depth.
Nodespace (0x0A)	Strategy	Kōji Interactive	Turn-based territorial control. Go-like positioning. CLAIM, FORTIFY, SCOUT, WAIT. AI personalities: AGGRESSIVE / DEFENSIVE / ADAPTIVE / ASYMMETRIC. ASYMMETRIC opponents have multi-phase strategies the operator must infer (Consolidation → Expansion → Severance).

Hot Swap. Cartridges are physically swapped mid-mission. The screen blacks for ~2 seconds. The operator is exposed. Multi-phase contracts use this deliberately — Phase 1 ICE BREAKER → Phase 2 Black Ledger is the canonical Corporate Espionage chain.

The other ten modules in the canonical fourteen exist diegetically (operators have heard of them, mission briefs reference them) but are off-screen for the events of The Amber Circuit.

Character Pronoun Registry

Character	Pronouns	Note
Wreck	they/them	Gender deliberately ambiguous throughout. Never resolve. Operator since before the burn — current run is a relapse with new handle, zero rep, zero credits. The muscle memory predates the device they’re now using.
Mace	he/him	61, equipment broker, basement under Waterfront Station. Confirmed in Amber-and-Dust synopsis.
Silicate	she/her	47, former corporate security AI researcher. Rival-then-peer to Wreck.
Corsair	he/him	One-scene rival operator encountered at the Docks.
Reeves	he/him	Dead three-and-a-half years prior. Cautionary legend referenced by Mace and Black Ledger forensic finds.
Yoon	she/her	Past partner from Wreck’s courier years. Off-screen, referenced briefly in Wreck’s interiority.

Timeline

Stories in the Deckline Cycle are placed on an internal timeline anchored to the device’s revival, not to a real-world year. The Amber Circuit is set in Year 9 of the revived Deckline platform — chronologically the earliest of the dramatized events. Variance Analysis, The Lisp Machine, and The Operator’s Manual occur later in the same year or shortly after.

The 1988 / 1992 / dissolved-thirty-six-years-ago references in stories are durations relative to in-fiction “now,” not absolute calendar years. Treat them as canonical regardless of when the reader picks up the book.
