EDFM + MINC matrix–fracture transfer
Research-grade — validation in progress.
Closed-form Embedded Discrete Fracture Model face transmissibility (`edfmTransmissibility`, Li–Lee 2008 / Moinfar 2013 average matrix-to-fracture distance) plus a nested MINC subgrid transient (N shells, harmonic-mean inter-shell transmissibility, implicit-Euler tridiagonal solve) in `src/lib/reservoir/edfmMinc.ts`. Complements the Warren–Root λ / connectivity-index helpers in `src/lib/embeddedDfnConductivity.ts`. Workspace surface `/edfm-minc` exposes shell count, matrix k/φ/c_t, fracture spacing and contact area, and reports T_mf, per-shell pressure history and the equivalent dual-porosity λ so unstructured-grid claims can be checked against the closed form.
Closed-form transfer only — the EDFM faces are not yet assembled into the 3-phase black-oil IMPES grid, so full multiphase EDFM sector runs still route through the structured voxel path. Next ship: contribute EDFM transmissibilities directly to the `compositionalBlackOil3P` pressure matrix and let DFN geometry from `dfnGraph.ts` generate the faces automatically.
