Multiple Sources and Duplicate Notices

A monster might reference a custom feat, which in turn references a Core Rulebook prerequisite, which itself credits the original System Reference Document. Each link in that chain has its own copyright notice — a compliant Section 15 block needs all of them, not just the one you personally looked at.

This site's chain-walk resolver follows a record's own reference graph — its "Derived From" citation, plus anything that record itself cites — and compiles the full set of upstream sources automatically. The site's own Section 15 register (visible on the Guide Hub) is built the same way at the site level: every distinct source actually cited by any published record, listed once each.

Publishing a record whose own chain includes something not yet published itself is blocked at publish time — this prevents an "orphaned" citation where your notice points at a source that was never actually made public.

If two of your sources both ultimately credit the same upstream work (e.g. two different Bestiary entries both crediting the Core Rulebook), that shared source is only listed once in the compiled rollup — not once per path that reaches it. The same discipline applies to the site's own sitewide register.
