Ch.12 — Hardware Bridge (FPGA / KOSCHEI)

Master: trios#380 GOLDEN SUNFLOWERS Book
Priority: ⚪ P2 defer · Word target: 500 · Owner: defer post-hackathon

🎯 Scope (FROZEN)

FPGA iCE40 GF16 ALU implementation (existing in t27/gen/). KOSCHEI opcode 0xD6 (TEMPORALTRITQUERY). Power/area numbers vs IEEE/MX. Why this matters for edge inference.

🔑 Key claims / formulas

• iCE40 GF16 ALU LUT count vs FP16 ALU
• KOSCHEI 0xD6 single-cycle TEMPORALTRITQUERY
• Power: estimated mW per op
• Area: gates per format

📦 Deliverables

• paper/sections/12_hardware_bridge_fpga__koschei.tex
• Defer for hackathon submission (not in 16MB scope)
• Reserve for arXiv v2 paper post-hackathon

🔗 Dependencies

• Ch.4 GoldenFloat

📝 Draft (Markdown — paste here when ready)

Operator types наполни Ch.12 → General fills this section with research-backed Markdown.

✅ Definition of Done (NeurIPS checklist aligned)

• Word count 500 ±10%
• All claims cited (primary literature, not just our repos)
• No AI as author (Acknowledgments only)
• Compiles in main.tex via tectonic, no warnings
• Limitations stated (where applicable)
• Reproducibility info present (where applicable)
• PR with Closes #<this> + green CI
• L1 (no .sh) · L3 (clippy zero) · L4 (tests pass) · L8 (PUSH FIRST)

🤖 ONE-SHOT directive (когда operator typed ONE SHOT Ch.12)

A CHAPTER-AGENT: take Markdown draft from this issue body §"Draft", convert to LaTeX,
place in paper/sections/12_<slug>.tex, ensure compile via tectonic with main.tex,
open PR linked to #, run cargo clippy/test, push, request review.
Hard deadline per priority (P0 → T-3h, P1 → T-1h, P2 → defer).

❌ Closed — moved out of PhD scope per v2.1

woody-shop / WOODY / KOSCHEI / FPGA iCE40 / Sacred Core v6/v7 are CLIENT projects, not PhD. Ch.12 Hardware Bridge removed from book v2.1. New scope: software-only (Rust/Zig), no hardware/FPGA/KOSCHEI.

Replaced by:

• Ch.20 Live Dashboard (Rust axum) → 📖 Ch.9 — Live Dashboard (Rust + Neon + HTMX) (500w · 🟡 P1) #390
• Ch.22 Railway deployment → 📖 Ch.22 — Railway deployment plus Tailscale (400w · 🟡 P1 · V — INFRASTRUCTURE) #407 (new)
• Ch.23 MCP Server v2.2 → 📖 Ch.23 — MCP Server v2.2 endpoints (500w · 🟡 P1 · V — INFRASTRUCTURE) #408 (new)

🔄 RE-OPENED — scope clarified per operator directive 2026-04-30T16:46 +07

Sacred Core / KOSCHEI / FPGA iCE40 = author's research stack (NOT woody-shop commercial layer). Reverted closure decision. Chapter restored as Ch.12 Hardware Bridge with strict academic framing.

Scope (FROZEN, academic-tone)

NO "Sacred"/"Eternal"/"OS of time itself" terminology in tex output. NO Investor Deck / commercial framing.

For LaTeX paper:

• "Sacred Core" → "Period-Locked Runtime Monitor"
• "Eternal monitor" → "φ-period monitor"
• "KOSCHEI IS OS" → "KOSCHEI φ-Numeric Coprocessor ISA" (simple architecture name)
• Keep code paths in repo as-is (src/tri/eternal_monitor.zig) for reproducibility, but rename in tex narration: phi_period_monitor.zig

Falsifiable claims only

Claim	Measurement
φ-keyed interval (1618ms) reduces jitter	drift X% over 24h vs uniform 1500ms baseline
KOSCHEI 0xD6 TEMPORALTRITQUERY	N cycles on iCE40 HX8K @ 12MHz
Sacred ALU GF16 add/mul	K LUTs, M FFs, F_max MHz
LED heartbeat at 1618ms	visual reproducibility check

Honest limitations

• Simulation only (yosys+nextpnr), not silicon — admit explicitly in §12.4
• Trinity SAI Strand II (cognitive) — design-space exploration, not validated
• Not ASIC, no tape-out — "future work"

Disclosure paragraph (mandatory in §14)

"The author is also developing TRINITY OS, an open-source φ-time-keyed runtime; the FPGA prototype shares numeric primitives with this paper, but no commercial code is included. See companion preprint [TBD]."

Status decision (T-7h13m to operator target)

Per operator directive: option (B) for today — minimal Ch.24 KOSCHEI ISA only (~800w). Full Ch.25 FPGA Verilog + Ch.26 Sacred ALU + Ch.27 Trinity SAI = deferred to v3.0 post-hackathon roadmap.

Re-opening this issue as 🟡 P1 deferred (active in v3.0, not in today's submission cut).
