"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.
Test 5's asymmetric-collision fixture asserted a root-level param_space
["sma.length"] while also being "test 2's fixture with one leg swapped" (nested)
— a contradiction: check_fan_in_distinguishability only descends into composites,
so a root-level collision is not rejected today (not RED-first). Caught at plan
time while writing the verbatim fixture body.
Corrected: test 5 nests the asymmetric collision in an inner composite `asym`
(param-bearing Sma "sma" + paramless Pass1 .named("sma") + Sub, both leaves on
role price fanning into the Sub) under a source-bound root, asserting
param_space() == ["asym.sma.length"] (the single injective entry — the paramless
leg contributes no path) and that compile_with_params(&[I64(2)]) is Ok after.
Re-grounded PASS, re-panel unanimous SOUND. Forward correction on top of 7f059d0
(main is forward-only — no rewind of the boss-signed spec).

param_space() injectivity becomes a stated, enforced compile invariant. One
structural check (check_param_namespace_injective) replaces the fan-in machinery
(check_fan_in_distinguishability, check_composite_fan_in, signature_of,
leaf_has_param) and the AmbiguousKnob binder branch. The error is path-carrying
(DuplicateParamPath) and the binders run the check before name resolution, so the
canonical by-name author sees the structural cure (.named(...)) instead of the
AmbiguousKnob symptom. param_space() stays infallible; the invariant lives in the
compile step (C23).
Two render-identity-only fan-in rejections (asymmetric param/paramless collision,
role-vs-leg signature collision) are intentionally dropped — neither is a
param_space duplicate (every knob keeps a unique path), and the property they
guarded (render distinguishability) has had no live consumer since the renderer
was retired in 0026. The larger is pinned by a now-compiles fixture.
Boss-signed under spec_auto_sign: objective gates green (precondition clean,
self-review clean, grounding-check PASS without override) + a unanimous five-lens
spec-skeptic panel. The grounding lens first BLOCKed a false set-equality claim;
the user ratified dropping both render-identity cases, the spec was reframed onto
the injectivity scope, re-grounded PASS, and the re-panel returned unanimous SOUND.
