A unit of meaning, not a unit of text
Every thought DNAi has begins as a Competitive Informational Unit — a CIU. A CIU is not a sentence and not a token. It is a propositional commitment built from an NFD triad: a Name (the subject), a Form (declarative, causal, conditional, modal, temporal, or jurisdictional — the predicate type), and a Dharma (the function or lawful constraint the proposition asserts). Identical N+F+D collapses to an identical SHA-512 hash and is automatically deduplicated.
The closest molecular analogue is the codon: a minimal three-slot positional code whose meaning depends on the order and identity of its parts. A codon selects an amino acid; an NFD triad selects a propositional commitment. Both collapse a continuous signal into a discrete, position-sensitive vocabulary that downstream machinery — ribosome or cognition loop — can read. CIUs are the cells of DNAi's mind: each has identity, tier (HOT / WARM / COLD), a merit score, and a contradiction score; each is created, promoted, demoted, or atrophied as a single addressable entity.
