The 5.2.1 chassis and retained 5.1 content
SRD 5.2.1 (the 2024 revision) is licensed under the SAME CC-BY-4.0 grant as 5.1, so the choice between them is a DESIGN one, never a licensing one, and the corpus may draw on both.
5.2.1 is the rules chassis.
Where both SRDs print a rule or record, the 5.2.1 definition wins. Nonconflicting
5.1 catalogue material retains its own provenance. A *.srd52.ron file
transcribes 5.2.1 and says so in its source; no active id is defined twice.
The SRD 5.2.1 encounter tables are tables/encounter_xp_budgets.srd52.ron
(level 1–20, Low/Moderate/High XP per character) and
tables/cr_xp.srd52.ron (XP by CR). Battle sums the selected difficulty’s
budget for each party member, including mixed levels, and spends that
total on creature XP without a creature-count multiplier. Its strength dial
selects Low at −1, Moderate at 0, and High at +1; −2 halves Low and +2
doubles High as game extensions. The dungeon’s occupancy-rated chamber
allotments remain party blind and use the same CR→XP price table.
