DOCUMENT INDEX

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: 11 docs, 1–2: 1 docs, 2: 1 docs

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

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