🌍 EcoGrid Manifold Engine

Ultra‑low‑power spectral tension solver • NDH A3 governed architecture

EcoGrid is a continuous spectral‑tension engine designed to model instability, load imbalance, sustainability strain, and spectral drift across structured or synthetic environments — all under a strict 2,000 FLOP thermodynamic ceiling.

It implements:

• a dense 9×9 Laplacian relaxation solver
• a shock‑coupling injection layer
• a spectral stability metric
• dual implementations in TypeScript (runtime) and Python (scientific reference)
• expressive HUD glyphs defined in /config/visual_grammar.json v1.2

EcoGrid is built for clarity, ethics, and computational minimalism.

📐 Mathematical Formulation (Gated, Expressive‑Only)

The following equation is a conceptual governing anchor and is not executed directly by the solver:

$$\frac{dP}{dt} = -L \cdot P(t) + W_{in} \cdot I(t) - \nabla_P(\text{VFE})$$

NDH Gate:
This PDE is expressive‑only. EcoGrid does not implement a continuous solver.

---

🧮 Implemented Solver Update (Discrete, FLOP‑Bounded)

EcoGrid uses a bounded, deterministic relaxation step:

$$P_{t+1} = P_t - \alpha (L P_t) + \beta (W_{in} I_t) - \gamma \nabla_P(\text{VFE}_t)$$

NDH Gate:
This is the only mathematical form executed by the solver.

🧩 Why You Must Build the Testing Environment Before Running Tests

EcoGrid’s testing system is a governed scientific apparatus, not a passive test suite.

1. The solver and runtime pipeline must be structurally complete

Tests validate:

• Laplacian correctness
• shock propagation
• spectral stability
• FLOP ceilings
• TS ↔ Python consistency

These require the full pipeline to exist.

2. The test suite audits the entire manifold

EcoGrid tests:

• the manifold
• the adapter
• the solver
• the runtime pipeline
• the spectral gate
• the expressive grammar

3. NDH A3 governance requires pre‑test structural verification

Before tests run, the environment must demonstrate:

• correct lane separation
• correct file placement
• correct expressive grammar
• correct solver invariants
• correct FLOP ceilings

4. Empirically, building the environment demonstrates:

• deterministic solver compilation
• structural integrity
• expressive grammar validity
• spectral stability
• TS ↔ Python consistency
• reproducible runtime experiment behavior

Building the environment is the empirical proof that EcoGrid is ready to be tested.
