fieldtest: blueprint-name — 4 examples, 1 bug / 0 friction / 1 spec-gap / 4 working

Source-blind consumer run over the four cycle axes on the release
binary at 4ff85b9: the authoring loop lands the name in bytes, store
document, and traces/<name>/ (with the documented default collision
observable on the unnamed twin); the refusal battery is uniform and
op-indexed across the op route and the file intakes; a named blueprint
defaults its use-splice instance identifier as documented, two unnamed
splices collide, two named ones coexist; help/guide/glossary agree on
eleven ops and the render-name vs registry-label split. Finding B1
(sweep --list-axes ungated, mangled listing at exit 0) is fixed
RED-first in the preceding commit; SG1 (prefix variance in the refusal
prose) is ratified there in C24.

+Construct a graph from a stdin op-list
+
+Usage: aura graph build [OPTIONS]
+
+Options:
+      --release  Load the project dylib from target/release instead of target/debug
+  -h, --help     Print help
+
+Op-list reference (stdin: a JSON array of op objects, applied in order):
+  {"op":"source","role":"price","kind":"F64"}
+      declare a bound root input role of a scalar kind
+  {"op":"input","role":"price"}
+      declare an open input role (wired by an enclosing graph)
+  {"op":"add","type":"SMA","name":"fast","bind":{"length":{"I64":2}}}
+      instantiate a node ("name" optional; "bind" maps param -> typed scalar)
+  {"op":"add","type":"Session","name":"ny","args":{"tz":"America/New_York","open":"09:30"},"bind":{"period_minutes":{"I64":15}}}
+      an arg-bearing type applies "args" (closed, per-type-declared string
+      pairs) BEFORE "bind" — see graph introspect --node <T> for its args
+  {"op":"feed","role":"price","into":["fast.series","slow.series"]}
+      wire a role into one or more input slots
+  {"op":"connect","from":"fast.value","to":"sub.lhs"}
+      wire a node output into an input slot
+  {"op":"expose","from":"sub.value","as":"bias"}
+      name a graph output field
+  {"op":"tap","from":"sub.value","as":"spread"}
+      declare a recordable tap on a wire (expose's output-side twin)
+  {"op":"gang","as":"length","into":["fast.length","slow.length"]}
+      fuse two or more sibling params into one public knob
+  {"op":"doc","text":"..."}
+      declare the composite's one-line meaning (C29)
+  {"op":"use","ref":{"name":"agree"},"name":"gate","bind":{"sma.length":{"I64":9}}}
+      splice a registered blueprint (by "content_id" or "name") under an
+      instance name ("bind" path-qualifies the spliced instance's params)
+  {"op":"name","name":"ny_momentum"}
+      set the composite's render name, at most once per script (default
+      "graph" if omitted)
