Rationale for the conventions

In-depth:

This apparatus accompanies Dating the Birth of Jesus. The main text carries out the derivation and bears its source references in footnotes; the lists of authors per position are there as well. What the footnotes do not bear — the distribution of authors per axis, the tables, the code, the kill matrix and what has not been seen — is here.

Two citation systems. Author-year (APA) does not fit AJ 17.167, RPC I 4242 or ILS 918. Hence: APA 7 for modern literature (§II.2), and a separate convention for ancient, epigraphic, numismatic and documentary sources (§II.1), naming the edition used where that edition bears the datum. The footnotes use the short form (author + year + page, or the ancient abbreviation); the full details are in §II.

The status of each datum — the mark — is not in the reading text. How a datum was consulted (firsthand, in transmission, calculated, construed, or not seen) is a control datum, not a reading datum; it would cloud the running text. Hence the footnotes carry no marks. The marks stand where they belong: in the Register of constraints and sources (§IV below, which sets each constraint beside its source and its status) and in the machine-readable base register deposited with this work (Visser, 2026b; https://doi.org/10.5281/zenodo.22944959).

The legend of the marks (for the register and the appendices): SEEN, PRIMARY / SEEN FIRSTHAND (firsthand, as page image, own count or calculation), DOCUMENTED (transmission — summary, translation, OCR; does not bear on its own), CALCULATED (derived arithmetically or by machine), CONSTRUED (a reading or inference, not a measurement), NOT SEEN (not consulted, without weight).

By machine wherever a machine could. The author register per axis (§III) comes from the data files of the deposit; the tables (Appendix A) and the kill matrix (Appendix C) come from `logigram.py` and are its output. The bibliography (§II.2) is grounded in the references in the main text and in the primary reading notes — no bibliographic field has been filled in where the source did not bear it.

Nowhere is a proof claimed. Not in this apparatus either. There is a cheapest reading with the prices of the rivals beside it, and a register that traces every step back to a source.
