Book Oracle: technology

A book oracle is not a quotation chosen to fit the question. Corpus, selection method, and exact locator are fixed before interpretation.

Digital mode

The server commits before client entropy. The question is hashed into the precommit for integrity but is excluded from locator-selection seed derivation.

Physical book

The user performs the physical action. OmenHall records book, edition, locator, and optional passage without claiming that physical opening is uniformly random.
