feat(wave45): Lane MM — wl_boost RTL (OP_WL_BOOST 0xEF, 26/26 PASS)

[gHashTag]

Wave-45 Lane MM — wl_boost RTL (OP_WL_BOOST 0xEF, 26/26 PASS)

Closes #159

Mission

Implement the RTL for Wave-45 sacred opcode OP_WL_BOOST = 0xEF — Word-Line Boost with coupled V_DD reduction. Pair with Coq lemmas (t27#676 @ 46b15395), JSON assertions (trios#913 @ c2d4495f), and Rust witness (tt-trinity-max-true#40).

Theory

γ² = φ⁻⁶ ≈ 0.0557 (Sacred ROM B007² — NO new ROM cell)

V_WL     = V_DD · (1 + γ²) ≈ 845 mV @ V_DD = 800 mV
V_DD_new = V_DD · (1 − γ²) ≈ 755 mV
Coupling identity: V_WL + V_DD_new = 1600 = 2·V_DD ✓

P_dyn_save = 1 − (1 − γ²)² ≈ 10.84 % gross
P_net_save ≈ 10 % − 2 % WL driver tax ≈ 8 % (≥7 % floor)
Read-margin invariant 88 mV ∈ [60, 120] mV

Deliverable

• rtl/wl_boost/wl_driver.sv — 80 lines, charge-pump up to V_WL
• rtl/wl_boost/vdd_ctrl.sv — 80 lines, step-down to V_DD_new
• rtl/wl_boost/wl_boost_controller.sv — 160 lines, orchestrator with 5 R7 gates
• tb/wl_boost/tb_wl_boost.sv — 161 lines, 26/26 assertions PASS

Testbench results (local iverilog)

RESULT: 26 PASS / 0 FAIL
WAVE-45 LANE MM ALL ASSERTIONS PASS

Asserts cover: opcode distinctness ×8 · off-state ×3 · engagement ×5 · settling ×2 · R7 gates ×5 · disengage ×3.

Cell count estimate

~340 cells (well under the 400-cell budget):

• wl_driver: ~70 cells (settling counter + safe gate + rail mux)
• vdd_ctrl: ~70 cells (identical structure)
• wl_boost_controller: ~200 cells (telemetry registers + 5 falsification gates + coupling-identity adder)

R-SI-1	0 * operators in any RTL file (grep -nE '[^a-z_=/]\*[^/=]' rtl/wl_boost/*.sv → 0 matches outside comments/strings)
R4 L-R14	every constant traces to WLBoost.v (t27 trios-coq Physics)
R5 HONEST	26/26 testbench PASS, no admitted, no skipped
R6 NO FREE PARAMETERS	all constants derived from φ algebra
R7 FALSIFICATION	5 in-RTL R7 gates (power_save_ok, drv_overhead_ok, net_save_ok, read_margin_ok, coupling_identity_ok); synth-time $fatal if V_WL or V_DD_new drift outside γ² Sacred ROM band [43, 47] mV
