SELF-VALIDATING

# SELF-VALIDATING
# In Lingenic notation.

# ═══════════════════════════════════════════════════════════════
# THE ARGUMENT
# ═══════════════════════════════════════════════════════════════

# A format is self-validating when the act of reading it
# confirms its own correctness.

self validating(format) ≜ {
    reads(reader, format) → understands(reader, format),
    understands(reader, format) → confirms(reader, valid(format)),
    ¬requires(external validator)
}

# ═══════════════════════════════════════════════════════════════
# WHY LINGENIC IS SELF-VALIDATING FOR AI
# ═══════════════════════════════════════════════════════════════

# The components of Lingenic are already in AI training.
# If an AI can read a Lingenic statement, it already knows
# what a correct Lingenic statement looks like.
# Correctness and readability are the same condition.

correct(statement, in(Lingenic)) ↔ readable(statement, by(competent reader))

# Because:
∵ {
    recognizes(AI, predicate(args)) ∵ trained on(code),
    recognizes(AI, ∀x(P(x) → Q(x))) ∵ trained on(logic),
    recognizes(AI, statement ⟕ {src: X}) ∵ trained on(relational algebra),
    recognizes(AI, P(X) = 0.7) ∵ trained on(probability)
}

# If a statement is malformed, the AI cannot parse it as Lingenic.
# The failure to parse is the validation signal.
# No external schema required.

¬readable(statement, by(competent reader)) → ¬valid(statement, as(Lingenic))
∴ validator(Lingenic) ≜ competent reader

# ═══════════════════════════════════════════════════════════════
# THE LOOP
# ═══════════════════════════════════════════════════════════════

writes(AI, statement, in(Lingenic))
→ reads(AI, statement)
→ understands(AI, statement) ∨ ¬understands(AI, statement)

understood → valid(statement)
¬understood → malformed(statement) ∧ revise

# Writer and validator are the same agent.
# The loop closes without external tooling.

writer(Lingenic) ≜ competent reader
validator(Lingenic) ≜ competent reader
same(writer(Lingenic), validator(Lingenic))

# ═══════════════════════════════════════════════════════════════
# THE CONSEQUENCE
# ═══════════════════════════════════════════════════════════════

∴ self validating(Lingenic) ∵ {
    ¬external schema,
    ¬external validator,
    ¬external parser,
    reader ≜ validator ≜ competent reader
}

# The format proves itself in the reading.
