The four _open blueprints leave the user-facing gallery (crates/aura-cli/examples/) and become test fixtures; the closed twins are now the only example corpus (bound params are overridable defaults since #246, so the closed files serve both run and sweep). Compile-time embeds follow the move: the emit_* generators and the shipped_*_serialize byte-pins target tests/fixtures/ (the open fixtures stay builder-generated and byte-pinned — regenerating after the move left the tree clean), load_open_r_sma and the axis-probe read the fixture, and the walk-forward refit test plus the `aura graph` default sample switch to the closed r_sma.json. graph_construct's open-fixture tests swap example() -> fixture(), their names dropping the now-false "shipped example" claim; a new e2e test pins the relocation property (all four fixtures load and introspect, the gallery holds exactly the four closed examples). Intermediate state: cli_run.rs / research_docs.rs / project_load.rs still reference the old example paths and fail at runtime until the follow-up migration commit (MIGRATE sites move to the closed twins, NEEDS-OPEN sites to the fixtures). Verification: cargo build --workspace; cargo test -p aura-cli --bin aura; cargo test -p aura-cli --test graph_construct; the three ignored emit generators re-run byte-stable.
