The three hand-kept copies of the 22-key zero-arg roster in
aura-std/vocabulary.rs (std_vocabulary match arms, std_vocabulary_types
list, the test's inline array) collapse into one private declarative
macro invoked once with the "TypeId" => Type pairs — the resolver and
the enumerable list now agree by construction (the #160 failure mode:
a node resolvable but silently absent from graph introspect
--vocabulary, or vice versa). Byte-preserving: same fn signatures, same
22 ids, same order; lib.rs re-export and every consumer untouched; the
vocabulary stays a closed compiled-in set (invariant 9 / C24 — a
compile-time expansion, no registry). Adding a zero-arg node is now one
roster line plus the conscious count-pin bumps.
Tests: the two unit tests reshaped (round-trip iterates the generated
list with PrimitiveBuilder::label() as the independent oracle; the shape
test keeps the count pin as deliberate friction). The E2E phase added
one cross-boundary pin beyond the plan — kept:
graph_introspect_vocabulary_lists_exactly_the_closed_roster_count checks
the same count through Env::type_ids() and the CLI print loop across the
real process boundary, which no roster-internal test can see.
Accepted residual (documented at the roster site, recorded on #160):
a new zero-arg node never rostered at all stays unguarded — no
enumeration of zero-arg builders exists — and fails safe in both
directions (clean UnknownNodeType on load; merely absent from
--vocabulary).
Verification: cargo build clean; cargo test --workspace 885 passed /
0 failed (884 baseline + 1 new e2e); clippy --all-targets -D warnings
clean; cargo doc --no-deps 0 warnings.
