WHAT TO EXPECT

Documents in this subfolder follow the project's 4-tier evidence system:

Tier 1 (Verified): Peer-reviewed, archaeological record, primary texts
Tier 2 (Credible): Academic, debated but supported by evidence
Tier 3 (Speculative): Possible but unverified
Tier 4 (Dubious): No credible source or contradicted by evidence

Tier distribution in this subfolder: 1: 6 docs, 1–2: 3 docs

Each document includes a Quick Summary, tiered claims with specific evidence,

counter-arguments, bibliography, and cross-references to related documents across the corpus.
