# The Siegel Stack

Five PRs, one causally-closed pipeline from atoms to on-chain ed25519 attestation. Each PR is a layer; read in fabrication order.

## Layer 0 — Fab (atoms)
**horse#13** merged · `bcf-0034..36` · $3,801 remaining BOM

Bambu Lab H2C (TPU 85A–95A for electrode gaskets, 325³ build volume for single-piece ShitBCI headframes, multi-material prints *mirroring* the colored operad isolation stack). Oscilloscope already owned. EE bench: DMM, soldering, hot air, PSU, microscope — every line justified against a named debug scenario in the skill library.

**Invariant:** lab capex < one PLUX fNIRS Pioneer Kit.

## Layer 1 — PCB (boards)
**horse#12** open · `uncut-gems-v2/REDESIGN.md` · 3 tiers

- **T1** OpenBCI-compatible: ADS1299 + nRF5340
- **T2** Cognionics HD-72 64ch adapter
- **T3** ShitBCI: RP2040 + ADS131M08, <$15 BOM @ qty 1, ~$25 @ qty 1000 rigid-flex

`gayOS` submodule: 1-bit Xerox NoteCards TUI for skill browsing. `PLANTS.md` for SF lab biosphere (Flora Grubb sourcing, R2-hosted).

**Connection to Layer 0:** every tier is printable/assemblable on the bench from horse#13.

## Layer 2 — Ingest (parser)
**nanoclj-zig#21** open · `brainfloj` — **one-line change**

`parseDelimitedSummary` now skips `%`-prefixed lines alongside `#`. This is the full delta between *"OpenBCI GUI output errors"* and *"OpenBCI GUI output ingests natively into nanoclj-zig Clojure with GF(3) trit classification."* `examples/cyton_sample.txt` = 25-row synthetic fixture, full 20-column Cyton layout, Fp1/Fp2/C3/C4/P7/P8/O1/O2 10-20 naming.

**Connection to Layer 1:** T1/T3 boards write `OpenBCI-RAW-*.txt`; this is the parser that eats them.

## Layer 3 — Ambient (environment)
**asi-skills#3** open · `ikea-varmblixt-smart-lamp`

Matter-over-Thread donut lamp. Documents the *pairing-unpair quirk* (Thread credential rotation breaks BILRESA remote when Matter fabric joins — pair controller first, then re-pair remote). 6× power-cycle factory reset (no buttons). Exactly the ambient sensor/illumination layer for a BCI session.

**Connection to Layer 0–2:** lab lighting + Thread border router presence = predictable stimulus + wireless interference baseline for Layer 1 RF work.

## Layer 4 — Proof (chain)
**asi#87** open · `kolmogorov-codex-quest` · **mainnet green**

Three on-chain txs verified today: `publish` (27974 gas), `create_quest` with 2 APT escrow (4954), **`submit_solution` (978 gas)** with native `ed25519::signature_verify_strict` accepting a 153-byte BCS message.

Pipeline faithful to gay-mcp + gf3-trit-oracle SKILLs:
1. world-hopping from seed `0x626d6f727068` ("bmorph") — 6 worlds, GF(3)-balanced (−1,0,+1,−1,0,+1)
2. gay-mcp SplitMix64 hue → trit (warm→+1, neutral→0, cold→−1)
3. gf3-trit-oracle classifies skill chain; canonical padded if Σtrit ≢ 0 mod 3
4. bisimulation-oracle: dual sha3-256 Merkle roots (1794 wikidata leaves = 26×69; gaymcp color-trace leaves)
5. IdentityProof assembled, ed25519-signed by local oracle
6. BCS layout: `solver(32)‖quest(32)‖wiki_root(32)‖gay_root(32)‖skills(8LE)‖worlds(8LE)‖gf3(1)‖ts(8LE)` = 153 B exactly
7. 45 Python tests mirror all 10 Move `assert!`s in `submit_solution`

Side quest: `bmorphism_palette.json` — 12 colors from `0x626d6f727068`, n=7 loop closure.

**Connection to Layer 2:** brainfloj's GF(3) trit of a real session is a valid input to the `gf3_sum` field in IdentityProof. **The Siegel stack closes the loop from electrode gasket to mainnet receipt.**

## Layer 5 — Regulatory (humans)
**horse#16** open · `bcf-0058` · 615 LOC (zubyul, not Siegel — but same stack)

Maps 28 BCI devices → FDA classification → IRB tier. Gates Siegel's entire L0–L4 pipeline before any human sits in the chair.

| Tier | IRB? | FDA? | Timeline |
|---|---|---|---|
| 0 Wellness demo | No | No | Now |
| 1 READ research | Expedited (Solutions IRB) | No | Q2 2026 |
| 2 FUS within ITRUSST | Full board (Advarra) | NSR by IRB | Q4 2026 |
| 3 Novel/SR | Full board + IDE | FDA IDE | 2027+ |

References 21 CFR 882.5050/1400, 45 CFR 46, ITRUSST Consensus 2025 (MI ≤ 1.9, ΔT < 2°C), IEEE Std 2010-2023.

**Connection to Layer 0–4:** without L5, Siegel's PCBs cannot touch human skin beyond Tier 0. L5 is the permissioning layer that turns the mainnet receipt (L4) into lawfully-reproducible signal (L1→L2 on a real subject).

Every step has an artifact on disk or a tx hash. No speculative layers.

## Winner address
`0xaa58415c…5404274`

## Gas economics
One-time (publish+create): 32,928 gas
Per-proof (submit): 978 gas
Sustainable for repeated BCI-session → on-chain receipt flow.

## What's unconnected (yet)
- HyperNEM/PoincareBall embedding of the 6-world seed
- VCGAuction over quest bounties (currently first-come)
- Retrocausal influence: post-solve `proof_timestamp` → pre-solve session scheduling
