Ogham · E2/E4 · Manuscript & learned layer
Ogham Scriptorium
Manuscript Ogham is now an investigable system rather than a static table: write and round-trip standard manuscript Ogham, try several genuinely attested learned/cryptic keys, and inspect Bríatharogaim together with their manuscript transmission. This layer remains explicitly separate from Classical epigraphy and from the Modern Oracle.
This is a transliteration tool, not a translation of a modern name or sentence into Primitive or Old Irish. That distinction is preserved in the record model.

100+ learned keys
The tract preserves more than a hundred alphabetic keys and cryptographic devices. We execute only those whose rules can be reproduced without invention; the practical use of many variants remains uncertain.
Critical boundary
Normalized ≠ diplomatic
Normalized Old Irish is useful for teaching, but it is not a literal transcription of a single Book of Ballymote folio. The system stores witness status and does not flatten the three Bríatharogam series into artificially equal witnesses.
Important boundary: the encoder transliterates signs; it does not automatically translate a modern name into Primitive Irish or Old Irish. Cryptic keys belong to the learned manuscript tradition and are not presented as the normal writing practice of fifth- to seventh-century stones.
