Architecture

Yamete is more engineered than a joke app deserves. The whole point of the project is to demonstrate how I build code and design systems, so the documentation walks the same path the code does. One concept per page. Each page has a "why this exists" framing, the diagram, and the file-level pointer.

If you came here to read the joke, the home page explains the joke. If you came here to read the code, this is your sidebar.

The pages

  • Module graph Four SPM targets. One direction. Why each layer exists and what it refuses to know.
  • Signal pipeline Sensor or event to output, end to end. The shape of the bus.
  • Per-sensor detection gates Six gates between a raw sample and a published reaction. Why each one exists.
  • Fusion engine Consensus across three impact sensors plus a rearm gate that keeps a single tap from firing twice.
  • Sensitivity gate User-facing sensitivity becomes an inverted threshold band that decides which impacts even reach the bus.
  • Bus enricher One pre-fan-out pass that resolves the audio clip, picks the face, and stamps publishedAt. So every output sees the same reaction.
  • Response dispatch Independent subscribers on the bus, each gated by the per-output per-reaction toggle matrix.
  • Display / audio pairing How Yamete pairs monitor speakers with their displays via EDID, and the topologies where the pairing falls back to "we don't know."
  • LED flash detail Caps Lock PWM dithering + a damped spring on the keyboard backlight. The crash-recovery sentinel that puts the brightness back if everything explodes mid-pulse.
  • Concurrency model Swift 6 strict concurrency. Where each actor lives, what crosses isolation, why the bus is an actor.
  • Pipeline lifecycle How the orchestrator brings the bus, sources, and outputs up. How it tears them down without leaking the IOKit handle.
  • Source map Every Swift file in the project, one line each. The cheat sheet.
  • Testing Every layer of the test pyramid Yamete drives in anger.
