§name: String§persona_ref: String§given: String§ask: String§output_type: String§confidence_floor: Option<f64>§apply_ref: String§requires_context: Option<u32>§Fase 68.b — the step’s declared MODEL CAPABILITY requirement: the
context window (in tokens) the cognitive act needs. The §68.c resolver
maps it to the smallest concrete model that satisfies it (per the
resolved backend’s §68.a catalog); None → the backend default
(back-compat). Declare the NEED, not the vendor SKU (D68.1).
now_tz: Option<String>§Fase 91.a — the step’s declared cognitive timezone: an IANA name
("America/Bogota", "UTC"). When present, the runtime injects the
run’s captured instant — rendered in THIS zone — into the step’s
cognitive context (time_is_an_explicit_input, the §71 doctrine
applied to cognition). Format-checked at compile time (axon-T892);
full IANA membership is the runtime’s job (chrono-tz, §91.b).
Overrides a bound context’s now: for this step. None → no
temporal injection (back-compat).
guards: Vec<StepGuardNode>§Fase 119 (D119.4) — the governance applications declared in this step’s body, in source order. Empty for every pre-§119 program.
pix_ops: Vec<FlowStep>§Fase 119.f — the STATEMENTS written in this step’s body, in source
order: the PIX verbs (navigate / drill / trail / validate)
and the step-scoped invocations (probe … for […], use_tool … with …, a bare <Agent>(args) call, par { … }).
README’s pix/corpus family writes them exactly here, with a braceless
field list, and each produces a binding (as: relevant_sections) the
step’s own ask: then interpolates. So they are ELEVATIONS, the same
shape §119.c gave lambda/ots: dispatch runs them BEFORE the step’s
generation. Reusing the flow-level node types (no new AST shapes) is
the D119.4 doctrine — one concept, two positions.
