Universal ASCII–Language Coherence Ledger – Full 0–127

Reference & Interoperability Chain

Integrated with Expanded Interoperability Edition & All Linked Works

1. Purpose

This final ledger connects every printable and non-printable ASCII character (0–127) to its:

Graphemic unit
Phonetic/morphemic role
Etymon & linguistic lineage
Keyboard location & scan code
Electrical input → OS keymap → output flow
SGI verification status

It links all prior works for recursive interoperability:
