audit: cycle 0035 — drift-clean (node instance name in the graph model)
Close-audit for cycle 0035 (commit range 20000dd..0ae8320). Architect drift
review against the design ledger + CLAUDE.md: clean. No regression scripts are
configured (the architect is the gate); build + test + clippy verified green.
cycle 0035 tidy (clean):
- C23 preserved: the instance name is resolved to Option at authoring
(instance_name()), emitted only on the render/model surface, and dropped at
lowering — the compilat wiring is byte-unchanged.
- C14 preserved: model bytes stay deterministic; both golden twins (inline
model_golden + sample-model.json) moved in lockstep to the same two "name"
additions.
- C12/C19 untouched: the cycle adds no param-space surface; the param-ganging
alternative was deflected to idea #61 (not via name collision — param_space
is injective by design).
- Engine<->viewer lockstep intact: the conditional "name" producer (prim_record)
and its three consumers (adaptNodes, genDot leaf-emit, cellLabel) moved
together, protected by a prim_record unit test + a headless render guard.
The blueprint-viewer `SMA[length]` (a051571) and the compiled `Node::label`
`SMA(2)` are legitimately distinct surfaces (name-bearing blueprint model vs
value-bearing compiled view) — the split the ledger already draws at
INDEX.md:681-684, not drift.
