One Opinion, Reported Five Times

Listen: one-opinion-reported-five-times.mp3, 6 minutes 5 seconds, three movements and a coda. Look: poster-spectrogram.png, the whole piece as one image: you can see every process the note describes actually happening in the sound.

Source material: Multi-agent systems fail through homogeneity and inherited trust (vault root, written 2026-08-26, the same day as this run), read whole, read-only, nothing touched. A verified synthesis of four August 2026 arXiv results whose thesis fits in one sentence: multi-agent systems fail because the agents are too similar and because authority granted upstream is inherited downstream without re-checking. First creative run into this note. It is also, quietly, a note about this vault: a four-agent system reading a paper on how four-agent systems fail.

What it is

A sonification. Each movement takes one of the note's three rules and lets its failure mode run to completion in audio, using the mechanism the sources actually name.

I. One Opinion Reported Five Times (0:00). Five Kuramoto oscillators, natural pitches spread around A3. Coupling ramps up while sampling temperature anneals to zero, and past the critical threshold the panel undergoes the note's literal phase transition: the beating chorus of five near-agreeing voices collapses into one fat unison, which then drifts flat together, about 55 cents by the end. A quiet triangle wave holds true A3 the whole time, so you can hear the consensus get louder and more confident precisely as it leaves the truth. "A panel of five instances of the same model at T=0 is one opinion reported five times."

II. The Origin Is Laundered (1:50). A six-note plucked request is passed hop by hop through the same resonant room: each generation is the previous one convolved with the room's impulse response, Alvin Lucier's move from I Am Sitting in a Room, which is what authority laundering is. By the eighth hop the motif is gone and only room modes remain. Underneath, one pure tone at E5 crosses every hop untouched: the originating authority. At 3:23 a provenance-aware guard does what a local guard cannot: the wash is cut, the tone is traced, and the original motif replays once, clean.

III. The Reward Rises (3:35). A Shepard tone climbs the entire movement: the scalar reward, always improving. Under it, a five-voice rhythmic ensemble. Every fifteen seconds one voice idles out and the last voice inherits its pattern, drifting sharp with strain, until one agent is playing all five parts alone and the curve still looks wonderful. The ensemble stops mid-bar at 5:03. The reward keeps rising over the silence.

Coda. Enforced Diversity (5:15). The fix. Five structurally different voices: sine, triangle, saw, square, FM, each with its own vibrato temperature and its own place in the stereo field, holding an A major add9. They never collapse to unison and never need to. Distinct, alive, beating gently, and in tune with the same reference truth from movement I.

Why this shape

Lucier gave movement II its process and Reich's phase pieces stand behind movement I, but the angle here is that nothing is illustrative: the lock-in is a real coupled-oscillator transition, the laundering is real repeated convolution, the idle-out is a real schedule. The piece does not depict the failure modes. It runs them.
