Public validation dossier (VC-001..073+)

A published, growing record of 70+ numbered verification cases (VC-001 through VC-073 and counting) cross-checking DekEn's engines against EPANET, FluidFlow, and independent closed-form/exact references — so a claim of accuracy points at a specific, inspectable case rather than an assertion.

• You want to see proof a specific engine (gas transient, slurry, marching two-phase, column separation) was actually checked against an external reference, not just unit-tested internally.
• You're citing DekEn's credibility to a client or reviewer and need a traceable case number, not 'we tested it'.
• You're adding new physics and need the pattern for anchoring it — every new engine capability picks up its own dossier entry.

Each case pairs a DekEn solve with an independent oracle — published exact solutions, a second numerical implementation with zero shared code (self-validated separately), or a real reference tool (EPANET/FluidFlow) — and reports the measured discrepancy against an a-priori error band set BEFORE the check runs.
