Struct AssertionIR 

pub struct AssertionIR {
    pub assert_id: AssertId,
    pub predicate: PredicateIR,
    pub verify_via: Vec<VerifyChannel>,
    pub vision_prompt: Option<String>,
    pub on_missing_input: OnMissingInput,
}

A single assertion with its explicit verify-chain.

The three baseline allOf conditionals are reproduced on the generated schema via #[schemars(extend)]:

1. expr predicates consume no observation channel (verifyVia: []); all other predicates need at least one channel.
2. visual predicates are vision-only (verifyVia == ["vision"]).
3. For elementState/elementText, visionPrompt is required iff the chain contains vision, forbidden otherwise (03 §1.4 rule 5; the compiler never synthesizes vision prompts, principle 6).

“vision only at the chain tail” is order-sensitive and remains a bind-phase check (not expressible in JSON Schema).

Fields

assert_id: AssertId

Stable assertion id (unique within the step).

predicate: PredicateIR

The predicate to evaluate.

verify_via: Vec<VerifyChannel>

Explicit, ordered verify-chain — a subsequence of [dom, uiTree, vision]. Order carries semantics (degradation order) and participates verbatim in judgeHash (02 §12.1 rule 5). Uniqueness is enforced by the schema (uniqueItems), not by this type.

vision_prompt: Option<String>

Author-written vision prompt, handed verbatim to the VisionVerifier when vision is the declared degraded tail of an elementState/elementText verify-chain (YAML surface key visual). Required iff such a chain contains vision, forbidden otherwise. Part of the assertion, hence inside the judgeHash domain (02 §12.3).

on_missing_input: OnMissingInput

Const "unknown" (principle 4): a channel that cannot complete evaluation yields unknown for that channel and the chain advances; an exhausted chain yields unknown. A completed negative is final (spine R5).
