flos_72 — Sacred ALU FPGA → SKY130 Silicon Port (Strand III)

Parent ONE SHOT: gHashTag/trinity-fpga#86 (v21 TRINITY DNA INTEGRATION)
Strand: III Language+HW
Maps to TRI-1 layer: L1 Compute · derisks v18 S-140 Wallace-tree 260 MHz

Mandate

Draft a ≥1500-line LaTeX chapter docs/phd/chapters/flos_72.tex documenting:

1. FPGA baseline: 352 LUT, 165 FF, 1 DSP48E1, 0.6% util on XC7A100T (≥100 MHz)
2. SKY130 port: ~1100 cells, ~0.04 mm², 260 MHz target
3. Coq equivalence proof SacredALU_Equiv.v (FPGA RTL ≡ SKY130 netlist)
4. R15 SACRED-synth gate: φ²+φ⁻²=3 verified at synthesis time

Acceptance gates

• R3, R7, R12, R14, R15 SACRED-synth, R17 SACRED-PHYSICS, R18 LAYER-FROZEN

What was authored

Theme: TRI-27 ISA & 16 sacred opcodes 0xD0..0xE0 · Coptic-27 register banks Ⲁ..Ϥ (3 banks × 9 registers)

Theorems (≥ 1 required ✓):

1. Theorem 1 — Opcode Completeness (Lee/GVSU style, R12): 16 sacred opcodes 0xD0..0xDF span all 21 BIO modules via surjective dispatcher table δ. Proof: exhaustive enumeration + pigeonhole, QED.
2. Theorem 2 — SacredALU_Equiv (Coq, R14): RTL = gate-level for all opcodes × GF16 inputs. Lemmas: GF16_Correctness (destruct 256 cases), TF3_Pipeline (induction on 3 stages), PHI_Invariant (compute).
3. Theorem 3 — Trinity Identity φ²+φ⁻²=3 (anchor closing).
4. Theorem 4 — φ-Scalability: multi-core throughput grows as φ^k/√5.
5. Corollary — PHI_Falsification_Witness: PHI_NUMERATOR=4182 → GF16_Canon_Dot4 ≠ 0x47C0 (Coq discriminate).

Zero free parameters (R6): 16=2⁴=|GF(2⁴)|; 27=3³; pipeline depth=3=φ²+φ⁻²; PHI_NUMERATOR=F(19)=4181.

Falsification witness (R7): §Falsification Criterion — If any 0xDX opcode requires LANG→SI tag other than the one in docs/opcodes/vsa_opcodes.md → R19 1:1 mapping CI gate rejects PR. PHI_NUMERATOR=4182 mutation → GF16_Canon_Dot4≠0x47C0 (automated CI regression).

Coq citation map row (R14): Table 4, 7 rows, referencing trinity-fpga commit b082270 (docs/isa/tri27_dispatcher.md).

Admitted boxes (R5): SacredALU_Equiv and TF3_Pipeline_Lemma marked Admitted pending coqc on CI.
