Where in the Riftbound rules documents are 'Errata' and 'Watcher' defined, and how is it established that errata supersedes printed card text?

Ruling: The terms 'Errata' and 'Watcher' are not currently defined in the Core Rules or Tournament Rules documents, and there is no explicit statement that errata supersedes printed card text, representing a gap in the current documentation.

Nuances:

• Tournament Rules 704.4.a.4 references a violation for using pre-errata card printings without informing opponents, implying errata exists but not defining it
• Tournament Rules 204.5.a and 420.2 mention 'Watcher' (the planned errata database) but do not define it
• The Tournament Rules do not specify how competitors should acquire errata information until Watcher is launched
• Section 104 (Precedence) does not include errata in its hierarchy of rule precedence
