Sonic absence: predictions

Three circular voice scores surround a finite Rule 30 field, beside acoustic pitch-class energy and a next-symbol distribution.

Sonic absence: predictions

Nine bounded extension predictions were recorded before implementation. The earlier supplied prototype already had results; those are carried-in evidence and are not represented as new predictions. Confidence applies to finite program fixtures, rather than to people or music in general.

ID	Prediction	Check	Status
P1	The finite cone and exact edge strips agree with independent Rule 30 evolution.	Truth table, independent grid and comparisons through row 1024.	Held
P2	Late computation never rewrites a deadline or issued command.	Frozen original records and separate known-value replay.	Held in finite and browser checks
P3	Equal and five-limit major thirds differ by about 13.686286 cents.	Independent 400-cent and 5/4 calculations.	Held
P4	Every finite pulse count and rotation preserves evenly spaced cyclic gaps.	Sizes 1–32, all counts and rotations.	Held
P5	The score reader predicts before updating; forgetting changes future inference without rewriting receipts.	Hand probabilities, repetition, normalized distributions and eviction accounting.	Held
P6	Digital zero has no pitch; finite sine and missing-fundamental fixtures meet the declared error bounds.	440 Hz within 1%; 880 + 1320 Hz fixture within 2%; zero has no activity or key.	Held on these fixtures
P7	A time reversal can preserve all DFT magnitudes while changing ordered transitions.	Independently computed asymmetric sequence and reversal.	Held
P8	Arrangements change rendering procedures while retaining the finite cell gates.	Eight arrangements over the same frozen 64-step score; actual offline audio on a 32-step score.	Held in finite and browser audio checks
P9	Stop, mute, interruption and reset prevent unintended continuation; replay preserves the original.	Twenty actual browser lifecycle conditions; visibility event is synthetic.	Held in reviewed conditions; native browser save handling remains unverified

The thirteen extension checks include 13,759 comparisons. These results establish exact calculations and declared finite model behavior. They do not establish human pitch perception, enjoyment, awareness, cultural adequacy, a definition of music or a complexity lower bound for Rule 30.
