🧠 MFid Philosophy Statement

MFid (Mechanical Firmware Index) is a composite measure of system fidelity — defined not only by what is implemented, but how closely it aligns to what should be, based on deterministic logic, engineering intent, and observed behavior.

MFid scoring can be based on three tiers of evidence:

  1. Scientific Calculation Ground-truth mathematical derivations from physical law or architectural invariants.
    Example: Clock jitter bounded by Nyquist limits or thermal throttling modeled via TDP equations.
  2. Published Specification Comparison Real-world performance or reliability measured against vendor or standard specs.
    Example: NVMe latency vs. manufacturer whitepaper, Azure VM uptime vs. SLA.
  3. Engineering Estimation Expert heuristics, reasonable inference from observed patterns or incomplete telemetry.
    Example: Inferring integration fidelity from sync errors + anecdotal developer friction.

These three evidence tiers can coexist within a single MFid, with metadata noting the confidence class per metric.
