Digital philology increasingly relies on hybrid communities of human and computational agents. This paper proposes a logical meta-layer to formalise philological acts across three community types — ecdotic, exegetical, and hermeneutic — corresponding to evaluative, epistemic, and doxastic modal logics. Each community is defined by a shared triple of constraints: evidence (E), rules (R), and logics (L). By making implicit choices explicit and comparable, argumentative transparency becomes the operational condition of transhuman textual communities.
