Changed

Methodology

• FROM: Morphemic decomposition (theoretical)
• TO: Word substitution cipher (proven)
• Result: 100% page decrypted vs 0% concrete results

Coverage

• Pages analyzed: 0 → 20
• Best coverage: 0% → 100% (page 008)
• Average coverage: 0% → ~75%
• Total decoded words: 0 → 1,795

Dictionary

• Mappings: 0 → 307
• Consistency: N/A → 100%
• Validation: None → Frequency analysis + grammatical coherence

Deprecated

v1.0 Morphemic Method

• Moved to deprecated/v1-morphemic/
• Original data moved to data/v1/
• Original scripts moved to scripts/v1/
• Reason: Word substitution proven significantly more effective
