C29 compile/unit seam, core carrier (iteration 1 of the self-description
spec): DocGateFault { Empty, RestatesName } + doc_gate() — deterministic
string-shape check, never content judgement — and NodeSchema gains the
required pub doc: &'static str, so every construction site must declare
a meaning line (compiler-enumerated). Core's own 10 test literals thread
doc: "test-only schema"; doc_gate/DocGateFault re-exported at crate root.
Downstream crates are E0063-broken by design until their sites thread
the field (tasks 3-7 of the plan); gates here are crate-scoped:
cargo test -p aura-core (59 green) + clippy -p aura-core (clean).
Interim subset commit of the implement run after adjudicating a
cross-task discard: task 2's file checkout had destroyed task 1's
node.rs/lib.rs work; restored from the loop's recovery snapshot
53c55c3 and merged with task 2's field threading.
