Bind a sweep's axes by name instead of by a positional GridSpace:
bp.axis("sma_cross.fast", [2, 3]).axis("sma_cross.slow", [4, 5]).axis("scale", [0.5]).sweep(run)
The sweep half of spec 0030, completing the named-binding feature (#35). A pure
authoring layer over the existing GridSpace::new / sweep primitives; engine core
untouched (C1/C12/C19/C23).
This iteration:
- resolve_axes(): shares resolve's name->slot mapping (iter 1), adds the EmptyAxis
check (the variant defined in iter 1 is now first constructed here) and a
per-element axis kind-check (every element of each axis, first offending element
in axis order). Its validation is a strict superset of GridSpace::new's
(arity / non-empty / per-element kind), so SweepBinder::sweep's downstream
GridSpace::new(...).expect(...) is infallible by construction — it can never
panic on author input.
- Composite::axis -> SweepBinder -> SweepBinder::sweep (Result<SweepFamily, BindError>).
- The CLI sample sweep converted to the named form (behaviour-preserving).
Plan correction (verified by the orchestrator): the iteration plan said only the
GridSpace import was orphaned by the CLI conversion, but replacing the free
sweep(&grid, ..) call with the .sweep(..) method also orphans the free `sweep`
import — both were dropped from aura-cli to satisfy clippy -D warnings. The Scalar
import (from aura_core) stays used and was untouched.
Verified (run by the orchestrator): 6 new aura-engine tests green —
resolve_axes round-trip, EmptyAxis, MissingKnob, the per-element KindMismatch on a
mixed axis (the superset/no-panic guarantee), a builder no-panic wrong-kind test,
and a GridSpace .points() parity test; the two sweep JSON goldens
(sweep_report_renders_four_points_in_odometer_order + the cli_run integration
golden) green unchanged (name/value/order-preserving conversion); full
`cargo test --workspace` green and `cargo clippy --workspace --all-targets
-- -D warnings` clean.
