EA-CORPORA-04 seats two Greek corpora and repairs the chain that seats them.
Aristotle enters at 04/01: forty-eight works, 83,110 lines, united across First1KGreek and Perseus at pinned commits, with the genuine and the spurious carried undivided. The seat records the received authenticity status as a field to be tested against rather than a filter to measure through, and says why in its own source.json. The partition is an inference, not an attestation. Andronicus of Rhodes made it in the first century BCE from the cross-references the texts themselves contain; his catalogue is lost; and his judgments have since been reversed, since he held De interpretatione spurious and the field now receives it as genuine. Any analysis that drops the spuria to sharpen a claim about Aristotle has filtered its evidence through a category assembled out of the consistency it means to measure.
Plotinus enters at 04/02 for a reason rather than for completeness. Measured on particle-transition profiles across nine Greek authors, Aristotle sits nearer to Plotinus than to Plato, and nearer to Plotinus than to himself, across seven centuries and a change of dialect. Plato meanwhile sits nearer to Philo and to Thucydides than to Aristotle, and the Plato-Aristotle pair ranks tenth of thirty-six. What the feature space separates is verse from prose and then register; authorship is not visibly in the ordering. The seat exists so the finding can be contested rather than believed.
The deposit also records what could not be had: the seven lesser Thrasyllan spuria have no Greek edition in either upstream, and Iamblichus and Damascius are absent at every pin under any author string.
Finally it repairs an infrastructure defect of the same family as the capture-registry splitbrain. A seat is finished only when the seat directory, the machine index, a seating deposit and the rendered reading room all agree. The rendered surface had no generator and was made by hand, so it drifted: two corpora seated and indexed never reached the shelf, and the index listed seventeen of thirty-nine seats. A generator and a postflight gate now run the chain and fail when any surface disagrees. A corpus that exists only inside a data directory is not published; it is stored.
