# 33_Project_GoldenHair

Autologous keratin nanoparticle with iron-sulfur cluster core and gold shell.

**Project triad:** [BOUNTY_BOARD.md](BOUNTY_BOARD.md) · [WORLDLINE.md](WORLDLINE.md) · [FORM.md](FORM.md) · [BOOK.md](BOOK.md) · vault [§6 workflow](../README.md#6-workflow-applies-across-all-projects) · **Ring #33 of 33** — [`_VAULT_STATE.md`](../_VAULT_STATE.md).

### How this fits the argument

> **In one sentence:** GoldenHair tests whether Z₃-adjacent materials logic (LENG) can be embodied in a body-sourced instrument — hair as feedstock for a measured nanoparticle.

**The vault's unified argument** is in [THE_ARGUMENT.md](../THE_ARGUMENT.md). This project provides **materials bridge — autologous keratin, cubane Fe–S core, Au shell, macrophage-scale window**.

**Read first:** this README · **Depends on:** [05 LENG](../05_Project_LENG/README.md), [27 Wings](../27_Project_WingsAboveMorning/README.md), [08 Astronomicon](../08_Project_Astronomicon/README.md) (orem path) · **Feeds into:** unified instrument story if synthesis clears.

## Function

Design, model, and (eventually) synthesize a nanoparticle from the operator's own hair. Fe-S clusters provide Z3 point-group symmetry via cubane Td→C3 chemistry. Gold shell provides biocompatibility, SPR tunability, and fungal recognition surface. Size window 75-100 nm matches macrophage uptake route.

## Form

- **FORM.md** — Comprehensive tool inventory (in-house + orthodox + electrophysiology)
- **OREM design + engine** — Lives in `08_Project_Astronomicon/orem/` (shared with Astronomicon warp infrastructure)
- **Cross-project dependencies:** Lotus-Universalis (05), coupling tensor (27/10), constraint graph (**06** Daemon), spectral analysis (30), void / geo-temporal (29)

## Potential

The engineering holds on measured parameters. The theoretical η = 2/9 claim at molecular assembly scale was pre-registered and falsified. Z3 point-group symmetry from cubane chemistry is confirmed. Next gate: collaborator with glovebox + EPR.

## Status

DESIGN phase. No synthesis initiated. Guardrails active.
