Steinmetz Corpus Completion Matrix

Why This Exists

The site now has a large processed corpus, but a definitive Steinmetz archive must also know what it has not processed yet. This matrix keeps every major work, paper, edition, archive, and patent-frontier item visible so the project cannot mistake broad coverage for completion.

49

Bibliography records

Registered Steinmetz works and source targets in the control manifest.

15

Processed source records

Sources with source catalog entries and generated reading surfaces.

14

Critical frontier items

High-value Steinmetz works that must be acquired or explicitly deferred before completion.

11

Seeded patent examples

Patent examples currently registered before the full 200-plus authority pass.

Completion Rule

Steinmetz completion requires every critical work to be either processed with visible custody or explicitly deferred with a public reason; patents require a separate authority pass beyond the seeded examples.

Critical Acquisition Frontier

These are not optional decorations. They are the works most likely to change the depth of the archive: hysteresis, complex quantities, magnetic force language, general circuit equations, lightning, impulse currents, cable discharge, and cumulative surges.
