 | # | Component | Computes | Analog primitive | Reuse source (no tapeout) | Feedback path (nudged phase) | Tolerance status |
 |---|---|---|---|---|---|---|
 | 1 | Token embedding | table lookup | **digital** (SRAM lookup + DAC line drivers) | any MCU/FPGA + DAC array | none (input boundary) | n/a |
-| 2 | RoPE | fixed per-position 2×2 rotations on q,k | **I/Q quadrature mixer**: cos/sin DDS + multiplying DACs | century-old RF practice; COTS mixer/DDS chips | transpose = rotation by −θ — **same mixer, negated sin** | phase error ≈ position blur — expect very tolerant; **E-tier item (queued)** |
-| 3 | qkv / attn-proj / SwiGLU w1,w3,w2 / head | matrix–vector products | **crossbar arrays** (the bulk of all compute) | Demo-0/1: **SRAM-CIM (Shanbhag DIMA class)**; alternatives: Mythic flash CIM, IBM HERMES PCM eval | J^T reads = **bidirectional crossbar access** (the known PAR price; standard in every analog-EP proposal) | wq8 safe / wq6 marginal (looped-era static-tolerance); **re-run on cascade in E-tier** |
-| 4 | QK-norm (full-width RMS) | q,k ← q/rms(q)·g | **divisive normalization**: square-law devices + KCL current sum + divider/AGC | same primitive class as softmax normalization periphery | Jacobian symmetric — self-transpose, no extra hardware | divider mismatch/offset — **E-tier item (queued)** |
-| 5 | Softmax (causal) | exp + row-normalize | **Elfadel–Wyatt "entropic resistor"**: subthreshold-exp devices + KCL normalization (log-sum-exp co-content) | classic analog-VLSI circuit family; small arrays demonstrated | softmax Jacobian diag(p)−pp^T is symmetric; the QKV coupling around it is the non-reciprocal part | ±1% device mismatch → ±1% softmax error (linear); QK-norm bounds its input range. Dynamic-noise cliff (fnoise ≥1e-3, looped-era) **re-test on cascade = E-tier** |
-| 6 | SwiGLU gate | silu(w1x) ⊙ (w3x) | sigmoid = differential pair (native); ⊙ = **Gilbert/translinear multiplier** per unit | textbook standard cells | transpose of ⊙ = multiply by the partner signal — cheap | per-multiply mismatch/noise, 1408 wide — **E-tier item (queued)** |
+| 2 | RoPE | fixed per-position 2×2 rotations on q,k | **I/Q quadrature mixer**: cos/sin DDS + multiplying DACs | century-old RF practice; COTS mixer/DDS chips | transpose = rotation by −θ — **same mixer, negated sin** | **E-tier w1: 0.03 rad FREE; 0.1 rad ΔCE +0.012, cos_clean 0.92** — ~2° I/Q phase accuracy suffices (easy) |
+| 3 | qkv / attn-proj / SwiGLU w1,w3,w2 / head | matrix–vector products | **crossbar arrays** (the bulk of all compute) | Demo-0/1: **SRAM-CIM (Shanbhag DIMA class)**; alternatives: Mythic flash CIM, IBM HERMES PCM eval | J^T reads = **bidirectional crossbar access** (the known PAR price; standard in every analog-EP proposal) | **E-tier w1 (cascade): wq8 FREE (ΔCE +0.004, cos_clean 0.96); wq6 MARGINAL (+0.051, 0.81); wq4 DEAD (+2.23)** — ≥7b effective weight precision is the binding spec; wave-2 lever = quant-aware co-training |
+| 4 | QK-norm (full-width RMS) | q,k ← q/rms(q)·g | **divisive normalization**: square-law devices + KCL current sum + divider/AGC | same primitive class as softmax normalization periphery | Jacobian symmetric — self-transpose, no extra hardware | **E-tier w1: 3% mismatch FREE (ΔCE +0.003, cos_clean 0.95); 10% MARGINAL (+0.042, 0.78)** — 3% device matching is routine |
+| 5 | Softmax (causal) | exp + row-normalize | **Elfadel–Wyatt "entropic resistor"**: subthreshold-exp devices + KCL normalization (log-sum-exp co-content) | classic analog-VLSI circuit family; small arrays demonstrated | softmax Jacobian diag(p)−pp^T is symmetric; the QKV coupling around it is the non-reciprocal part | ±1% device mismatch → ±1% softmax error (linear); QK-norm bounds its input range. **E-tier w1: forward additive state noise σ=1e-2 FREE (ΔCE +0.001, cos 0.97) — the looped-era 1e-3 cliff does NOT transfer to cascade** |
+| 6 | SwiGLU gate | silu(w1x) ⊙ (w3x) | sigmoid = differential pair (native); ⊙ = **Gilbert/translinear multiplier** per unit | textbook standard cells | transpose of ⊙ = multiply by the partner signal — cheap | **E-tier w1: 10% gain error ΔCE +0.006, cos_clean 0.945 — FREE** at translinear-practice tolerances |
 | 7 | RMSNorm ×2 per block (norm-after-sublayer) | bound each sublayer output | divisive normalization (as #4), **no mean-subtraction path** (cheaper than LayerNorm) | same as #4 | symmetric Jacobian | as #4; ~4L+1 normalizers total = the largest NEW periphery count |
 | 8 | Residual stream | z + branch outputs | **current-summing bus (KCL node)** | wires | pass-through | norm-after bounds every injection — the arch change is itself the tolerance fix |
 | 9 | Final RMSNorm | bound pre-readout state | as #4 | as #4 | symmetric | bounds the **ADC** dynamic range at the digital boundary |
