**Claim (as registered):** Genre diversity (distinct recorded inscription-type values) is at least 8 in every eligible province.

**Proposed mechanism:** A cataloguing/vocabulary-breadth floor: any province with enough surviving, catalogued material to clear the minimum-support threshold is expected to have recorded a reasonably diverse range of inscription genres, not a narrow handful.

**Scope:** Source: the Epigraphic Database Heidelberg (EDH), a catalogue of Roman-period inscriptions on stone/metal/etc. (physical objects, catalogued separately from a manuscript census). Training: the 33 provinces in the alphabetically first half of EDH's own province-code order (42,009 inscriptions). Holdout: the 33 provinces in the alphabetically second half, minus 'Provincia incerta' (EDH's own catch-all for uncertain findspots, not a real geographic unit, excluded from all arithmetic) -- 32 real provinces, 39,457 inscriptions -- landed in one complete fetch after the claim was fixed. EDH's own content has been fixed since 2021 (the cataloguing project's funding ended), so this holdout tests whether a pattern generalizes across an arbitrary alphabetical split of already-catalogued, unchanging material, not whether it predicts new discoveries. Minimum support: at least 150 genre-typed rows in a province. 41 distinct genre values exist across the whole corpus.

**Training-side evidence:** Observed training-side minimum: 11 distinct genres (in a small southern-Italian province, n=196 typed rows). Observed maximum: 36 distinct genres (in a large frontier province, n=5,947 typed rows).

**Holdout test and outcome:** Of 20 eligible holdout provinces, the closest approach to the floor was 14 distinct genres.

**Status:** Survived every eligible holdout province.
