A 27-node lattice (3³ — the lock) of capacitors tethered to their six face-neighbours, run as a real discrete wave equation. The offsets 0·1·2·3 seed each node in quadrature phase (×90° — the pulse states). One node is D34DB335 — the DEADBEEF sentinel, clamped to zero: a defect that scatters the wave and traps a mode near it. Pluck it, watch the standing wave form and reflect off the walls; undamped, the energy holds.
TRUE: a genuine standing-wave propagator — each capacitor voltage obeys the discrete wave equation v̈ᵢ = c²·Σ(vⱼ−vᵢ) − γv̇ᵢ over the six tethers, integrated with energy-conserving velocity-Verlet. Undamped, total energy holds to ~1–2% (the readout proves it live); the 26 live nodes carry 26 standing-wave normal modes. The D34DB335 dead node is a real lattice defect: clamped to zero, it scatters the wave and localizes energy around itself — a cavity dug by a sentinel.
SYMBOLIC: the 27 = 3³ "lock", the 0·1·2·3 read as pulse-states / quadrature phase, and DEADBEEF-as-"dead-shell" are David's doctrine layered onto the physics — labels, not claims. And it is a capacitor-network analogue of a standing wave, not a fabbed device: no real LC values, no impedances. The wave maths is exact; the silicon is metaphor.
