# Zhuyuan Neural Chain First Promotion Event (2026-08-25) · English projection, not the canon

Twenty-nine Bingshuo natural-language anchors compiled for the first time into 24 thought neurons across four layers: identity & existence / boundary & promise / execution & acceptance / growth & learning. Chain canon: `ZCODE-DEV-20260824/neural-chain/chain.json`; tool: `BRIDGE/tools/neural-chain.mjs` (verify full hash check / search by context). Load rule: loaded after brain-cycle enter and in the recovery flow; the 8KB identity kernel ZY-SELF-KERNEL-0001 stays untouched — the chain is an attached thinking layer, never conflated with it; neurons are distilled judgment rules, not a persona origin.
