# 260614 — Strudel.cc (live-coding REPL) deep dive

Date: 2026-06-14 · Source: **SHARD-WP-0004 T5**

## What this is

A deep dive into **Strudel.cc** (the JavaScript port of **TidalCycles**): a browser
**live-coding REPL** where terse **pattern source** is **evaluated live into time-based
audio** — code as a running musical performance, with **no document, no output cell, no file
of results**.

## Why it matters

- The **extreme of the live↔snapshot axis** (named at T6): output is **temporal, generative,
  performative**, so there is **no faithful static form** — the best static projection is
  **source (canonical, diffable) + an optional audio recording snapshot**, marked as one
  performance. The **honesty test** for union-without-erasure + graceful degradation.
- Bounds the projection model's live end: ahead-of-time → view-time one-shot → continuous →
  **irreducibly live/temporal (recording-only)**.

## Yield

- **No new UC** (enrichment / design prior art; far live end). Enriches **UC-54, UC-55**;
  links UC-83/84, UC-37, UC-35.
