actually runs
The schema_discovery.rs include_str! escape was not the only one:
tests/selection.rs's fixture() read
../../contracts/cultnet/interop/selection-vectors.fixture.json, the
same three-levels-up path shape, and 37 of 45 tests panicked on it
under cargo-mutants' isolated copy - confirmed on Yggdrasil after the
schema_discovery.rs fix alone still landed "cargo test failed in an
unmutated tree, so no mutants were tested".
selection-vectors.fixture.json is a checked-in input (not a generated
artifact), so it gets the same treatment as the 22 schemas: a
byte-identical vendored copy under
packages/cultnet-rs/contracts/cultnet/interop/, a drift test
(fixture_contract_matches_the_canonical_source, same skip-when-absent
shape as schema_discovery_contracts.rs), and the loader reads the
vendored copy unconditionally.
selection-vectors.cs-written.json is different in kind: it is the C#
reference's own generated output, produced only by a real cross-runtime
checkout running SelectionParityVectorTests with
CULTNET_WRITE_VECTORS=1. There is nothing to vendor - an isolated
Rust-only copy can never satisfy that test's premise regardless of what
this crate does with its own files. That one test now skips (with an
explanation) when the canonical contracts/ tree is entirely absent,
rather than panicking and failing the whole suite over a cross-runtime
artifact the isolated copy cannot produce by construction.
Verified locally by hiding contracts/ entirely and rerunning the full
suite (217 tests across every binary): unchanged pass count, same as
with it present.
