Task 1-2 of the bound-override cycle: PrimitiveBuilder::bind/try_bind stop capturing the bound value in a wrapped build closure and store it only as BoundParam data; build() merges bound values back into the full-arity vector at call time (ascending original position — behaviour-identical to the retired closure chain). This makes the reversal possible: unbind(slot) returns the param to the declared surface at its original order. aura-engine gains the path-addressed Composite::reopen (mirroring collect_params' prefix rules, lockstep with expansion_map) plus the read-only bound_param_space() enumeration (path-qualified BoundSpec with values) and the ReopenError/BoundSpec exports. An e2e proves a reopened param rebuilds from the freshly supplied value through compile_with_params, not the stale default. refs #246

//! `aura-engine` — the headless, UI-agnostic reactive SoA engine.
|
|
//!
|
|
//! Delivered across cycles 0003-0004 — the harness and its deterministic run
|
|
//! loop:
|
|
//!
|
|
//! - [`Harness`] — the closed root graph that runs (a flat node array + an index
|
|
//! edge table, topologically ordered) and its deterministic `run` loop: a
|
|
//! k-way merge of timestamped sources (C3/C4) driven through a wired DAG of
|
|
//! nodes, cycle by cycle, with freshness-gated recompute and the two firing
|
|
//! policies (C5/C6) deciding when each node re-evaluates and what it holds.
|
|
//! - [`Edge`] / [`Target`] / [`SourceSpec`] — producer->consumer wiring,
|
|
//! source->consumer wiring, and a declared source (its kind + target slots).
|
|
//! - [`BootstrapError`] — wiring faults caught once, at bootstrap (kind
|
|
//! mismatch, bad index, directed cycle).
|
|
//!
|
|
//! Delivered in cycle 0009 — the run report surface:
|
|
//!
|
|
//! - [`RunMetrics`] / [`RunManifest`] / [`RunReport`] — the `(manifest, metrics)`
|
|
//! pair C18 mandates per run, with [`RunReport::to_json`] for the structured
|
|
//! C14 face;
|
|
//! - [`summarize`] — the post-run pure reduction over a run's recorded
|
|
//! pip-equity + exposure streams into [`RunMetrics`]; [`f64_field`] bridges a
|
|
//! recording sink's `Vec<Scalar>` rows to it.
|
|
//!
|
|
//! Orchestration families of the atomic sim unit
|
|
//! (`(topology + params + data-window + seed)`) ship along three of C12's axes: the
|
|
//! **grid** axis via [`sweep`] over a [`GridSpace`] into a [`SweepFamily`], the
|
|
//! **window** axis via [`walk_forward`] over a [`WindowRoller`] into a
|
|
//! [`WalkForwardResult`] (C12 axis 3: rolling in-sample/out-of-sample splits, the
|
|
//! in-sample optimize closure-supplied), and
|
|
//! the **seed** axis via [`monte_carlo`] over a seed set into an [`McFamily`]
|
|
//! (C12 axis 4: Monte-Carlo *is* a sweep over seeds; both drive one shared
|
|
//! disjoint-parallel executor). The **seed** input itself ships too:
|
|
//! [`SyntheticSpec`] is a seeded `Source` producer (`Fn(u64) -> impl Source`,
|
|
//! C12 seed-as-input) whose stream is fully seed-determined, making
|
|
//! [`RunManifest`]'s seed a live captured input; the atomic unit's `-> metrics`
|
|
//! reduction ships via [`summarize`].
|
|
//!
|
|
//! Still to come (subsequent cycles): the broker-independent position-event
|
|
//! output and downstream broker nodes (C10), the random param-sweep
|
|
//! orchestration axis, and registry lineage across a family.
|
|
//!
|
|
//! Visualization is never here: it is a downstream consumer node on the streams.
