Milestone-scope fieldtest (closing functional gate) for "The World —
parameter-space & sweep" (issues #30-#36). Three curated end-to-end scenarios
derived top-down from the milestone promise, driven from the public interface
only (ledger + specs + rustdoc; no crates/*/src read), built and run from HEAD
via a downstream consumer crate.
Delivery verdict: GREEN. The milestone delivers its promise.
- mw_1 single run bound by name: .with("sma_cross.fast", 2).bootstrap() binds
and runs (12 equity rows); diagnostics precise and knob-named (UnknownKnob /
AmbiguousKnob / KindMismatch).
- mw_2 named-axis sweep + compare: .axis(..).sweep(run) yields a 4-member,
ordered (odometer), disjoint, non-constant SweepFamily; ranking from public
fields. CLI (aura sweep / aura runs rank) delivers the same with no Rust.
- mw_3 structural-constant negative space (deliberate): SMA2-entry's
definitional `2` has no honest expression today -> grounds #55. Out of
milestone scope; not a blocker.
Findings: 0 bugs, 2 working, 3 friction, 1 spec_gap. Verified independently
(re-ran all three from HEAD; confirmed a plain SMA-cross emits sma_cross.length
twice and the shipped CLI sample carries the fast/slow ParamAlias overlays).
Friction (routed to the forward queue, none blocks the gate):
- the promised sma_cross.fast/.slow names are not free — they require
author-added ParamAlias overlays, doubly mandatory because the canonical
2-SMA cross also will not bootstrap without them (IndistinguishableFanIn);
- the sweep closure drops back to positional bind + manual name re-zip.
spec_gap -> #55: the wished-for structural-constant consumer code is recorded
in mw_3 as #55's acceptance evidence.
This commit is the milestone fieldtest itself; it closes no issue. Closing the
tracker milestone stays a deliberate manual act on this green gate.

OK: named-axis sweep produced a comparable, ordered, non-constant family.
