Implementation plan for spec 0031 (#56). Three tasks:
1. aura-core PrimitiveBuilder instance-name mechanism (.named()/node_name(),
default = lowercased type label) — additive.
2. The engine mechanism + the full compile-coupled migration, as one task by
necessity: collect_params node segment, signature_of + fan-in re-keyed onto
the node name, ParamAlias / Composite.params / the Composite::new 5th arg /
aliases_on / check_alias_indices removed, every in-workspace Composite::new
caller and ParamAlias reference migrated, the mirror / top_level (inverted) /
signature / CLI-golden assertions updated — all under one cargo build/test
--workspace gate that enumerates migration completeness.
3. Ledger C9 + C23 amendments.
plan-recon (DONE_WITH_CONCERNS) surfaced two sites the brief missed, both now in
the plan: the sweep-golden twin crates/aura-cli/tests/cli_run.rs:214 (lockstep
with main.rs), and the model_to_json goldens — resolved as OUT of scope (the JSON
model emits the type label + factory param names, both node-name-independent, so
sample-model.json and the graph_model.rs golden stay byte-identical; the fixtures
migrate structurally only). signature_of stays -> String, re-keyed onto the node
name. fieldtests/ are frozen non-workspace records, out of scope.
