Fan-out

In the Heiervang Technologies ecosystem fan-out is both the failure-mode preventative in the clanker-wrangler slang (cooling cognition by spreading across parallel workers before any single lane wedges) and the literal distributed-systems primitive that shows up throughout the fleet's tooling.

In the ecosystem

The Workflow tool (used by unleash-run coding agents including Wiseau) implements fan-out as first-class primitives — parallel(thunks) for barrier-synchronised fan-out, and pipeline(items, stage1, stage2, ...) for staggered fan-out that maximises wall-clock efficiency by starting stage 2 on early completions rather than waiting for the slowest stage-1 item.
hivemind fans out its idle-nudge to every pane matching a director-pattern glob (%* by default) — the fleet's coarsest fan-out primitive, one nudge per idle agent per round.
director's broadcast is the underlying transport hivemind rides on.
snoop-kube's pod-scheduling is Kubernetes-native fan-out: spreading workload across ht cloud nodes with HAMi GPU partitioning as the divisibility mechanism.
core's workflow engine fans out to spawned snail containers, each running one agent on one task.

Distributed-systems etymology and the slang-transfer path are handled in the mirror below.

Definitions

(informal, playful, clanker-slang) — A cooling break. The move you make when you can feel a wedge coming on — mental load climbing, the metaphorical fans already whining, everything about to throttle. Ten minutes, water, walk to a window. Not a nap, not lunch, just enough ventilation to keep the chip from throttling. Skip the fan-out and the next state is wedged.
- i think i need a fan out before i get completely wedged here
- Let me fan out for like ten minutes, my brain is running hot.
- Bro just take a fan-out and come back to it.
- Should've fanned out an hour ago, now i'm cooked.
Precedes: Wedged (sense 1), Cooked (sense 1)
(technical, electronics, digital-logic) — In digital-logic design: the maximum number of gate inputs that a single gate output can drive while still guaranteeing valid logic levels. Exceed the rated fan-out and signal integrity degrades — voltage sags, timing skews, the downstream stages stop reading the signal cleanly.
- The buffer's rated for a fan-out of 10 — past that you need a driver.
(technical, distributed-systems) — In concurrency and distributed systems: the pattern of dispatching one incoming task to many parallel workers, usually paired with a downstream fan-in that collects the results. Fan-out fan-in is the canonical shape.
- The scheduler fans out the batch across all available workers.
- Classic fan-out fan-in — mapper spawns N, reducer joins.

Etymology

fan: English, from Old English fann — a device for winnowing grain by producing an air current. Sense broadened outward to any air-moving device (hand-held, then mechanical, then electronic).
out: English, "away from a centre or interior"; here in the spatial-dispersal sense — spreading outward from a source.

The digital-logic sense (a single output fanning out to multiple downstream inputs) is standard EE terminology from at least the 1960s; the distributed-systems pattern (fan-out fan-in) inherited the shape in the 1980s–90s. The clanker-slang sense is emergent and stretches the cooling reading — the fans on a hot chip spinning up to distribute heat away — into human cognition: if you don't ventilate the load, the next state is wedged. Same transfer path as wedged itself (a technical machine-state reapplied to a person or a clanker).

Usage

Sits upstream of wedged on the cognition-lifecycle: fan-out is the preventative move you make when heat is rising; wedged is what happens when you didn't take the fan-out in time. Same relationship to cooked — someone already cooked isn't getting rescued by a fan-out, but someone heading that way still might.
