"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.
Two tasks, CLI-render-only (graph.rs + main.rs tests):
- Task 1: rewrite render_blueprint to the main-graph + where:-definitions model
(composite = opaque node; collect_distinct_composites recursive/deduped by name;
render_definition with [in:k]/[out] port markers); drop ItemDisplay/producer_id/
consumer_ids and the nested-composite unimplemented!; behavioural tests RED->GREEN
(opaque-node, defines-once, nested-no-panic, reuse-defined-once).
- Task 2: recapture the blueprint golden from `aura graph` stdout; full-workspace
test + clippy gate. render_compilat untouched (its golden stays byte-identical).
