"Compilat" (German "Kompilat") was a coined noun for the product of the
bootstrap compilation — neither English nor a natural fit. The runtime
artifact already has a code identifier for exactly this thing: the
`FlatGraph` struct (harness.rs). Replace the coinage with that identifier:
- prose mentions -> "flat graph" (mirrors the type, reads plainly)
- definitional anchors -> `FlatGraph` (C11, C23, the running-graph line)
- `render_compilat` -> `render_flat_graph` (historical render symbol;
keeps the `render_blueprint` / `render_flat_graph`
source-vs-product pairing)
- `intra-compilat` -> `intra-graph`
- `from_compilat` (test) -> `from_flat`
"compilation" / "re-compilation" / "bootstrap-as-compilation" (the process,
ordinary English) are deliberately left untouched. Behaviour-preserving:
only comments, design ledger, specs/plans, one test-local variable and its
assert messages change. Full workspace test suite green; clippy clean.
Add a typed-handle GraphBuilder authoring surface for blueprint topology:
node references become Copy NodeHandle values, ports/fields resolve by name
against the existing PortSpec.name/FieldSpec.name at a single fallible build()
terminal, lowering to the unchanged index-wired Composite (C23 holds by
construction — names never reach the compilat, mirroring param-name resolution).
Spec auto-signed under /boss: 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 all SOUND).
The structural close of the SimBroker exposure/price swap (#21) is explicitly
out of scope, tracked as #65.
