Design spec for #56 — give every blueprint node a name so param-space
path-qualification and fan-in distinguishability both flow from one
author-controlled identity, and retire the index-addressed ParamAlias overlay.
A primitive builder gains an optional name (default = the node's type-label
string, ASCII-lowercased verbatim: "SMA"->"sma", "SimBroker"->"simbroker";
explicit names must be non-empty). param_space() becomes uniformly
<node>.<param> at every level including the root. signature_of and the C9
fan-in rule re-key onto the node name: two same-type siblings both defaulting
to "sma" collide and IndistinguishableFanIn fires correctly, so one act —
naming the legs "fast"/"slow" — fixes both the naming collision and the fan-in
check. ParamAlias / Composite.params / the alias index-check are removed
(Role.name and OutField.name untouched). Ledger C9 and C23 amended. One
cohesive iteration: the engine mechanism + in-workspace migration (CLI sample,
engine tests, sweep goldens, graph_model.rs, sweep.rs, lib.rs re-export) land
together since removing the struct is compile-coupled; fieldtests/ are frozen
non-workspace records, out of scope.
Boss-signed under spec_auto_sign: all objective gates green (precondition,
self-review, grounding-check PASS) and a unanimous five-lens spec-skeptic panel
(criterion / grounding / scope-fork / ambiguity / plan-readiness) returned
SOUND after one fix round. The panel's first round caught real defects — a
worked example written against a non-existent fluent API, a false [param:]
render-marker claim (the marker was removed in cycle 0020), and an
under-specified compound default name — all corrected and re-grounded before
the unanimous pass.
