1BTF

1-Byte Text Format

1BTF is a byte-oriented text representation layer.

Core

• One 1BTF unit = exactly 1 byte.
• Raw UTF-8 byte matching.
• No grapheme segmentation.
• No tokenizer.
• No final token.
• English letters are canonical.
• English words are not stored as 1BTF units.
• Duplicate English representations are not stored in other domains.
• Global IDs belong to the master registry.
• Runtime representation uses 1-byte local IDs.
• Original UTF-8 unit information is stored in the registry.

Package

• 1btf_master.bin — single master registry
• tables/ — individual 1BTF sub-tables
• manifest.json — package metadata and checksums

Runtime

Raw UTF-8 → exact 1BTF unit → 1-byte representation

1BTF is not a tokenizer and is not a final token format.
