aura new and aura nodes new follow their git init with a best-effort
initial commit (inline committer identity, warning-never-fatal, skipped
whenever the init itself was skipped per #204), so a fresh project's
first run stamps a real commit instead of an empty provenance block.
closes#243
- New clap family `aura nodes new <name> [--engine-path] [--namespace]`:
scaffolds a node crate as a SIBLING of the project root (Cargo.toml
with the aura-core path-dep, the parameterized Scale starter node,
roster macro, crate-scoped .gitignore + CLAUDE.md, own git repo) and
appends the `[nodes] crates = ["../<name>"]` pointer to the project's
Aura.toml. Refuses outside a project, on any existing [nodes] section
(incl. an empty crates array), and on an existing destination; joins
the load-phase bypass beside `aura new` (a scaffolder must work in an
unbuilt tree).
- The old single-tier scaffold() is gone; the crate templates live on
in scaffold_node_crate; dead-code bridges removed with their callers.
- tests/project_nodes.rs: attach + refusals + namespace override + the
full role-2 loop (scaffold, cargo build, vocabulary resolves
<ns>::Scale end to end).
- tests/project_sweep_campaign.rs fixture reworked to the two-tier
shape (aura new + aura nodes new --namespace knob_lab); the two
campaign acceptance tests are byte-unchanged and green.
