The reference runner: a component importing tests and exporting wasi:cli/run, composed with a suite via wac plug (this exists in prototype form in lann/wasi-test runner-cli/). Grow it toward libtest ergonomics:
--list (enumeration only — all() + getters, no run), name-substring filtering (--only earns its keep for bisection), fail-fast.- Human-readable progress on stderr.
- Canonical results JSON (see the results-format issue) written via
wasi:filesystem when the world provides it; stdout as fallback. Note the fragility lesson from webcrypto's composed driver: results-on-stdout works, but any stray print corrupts it — prefer the file path.
- Exit status distinguishes harness errors from case failures (adapters exit nonzero on harness errors; case failures are the aggregator's business — but the standalone runner should also support a "gate directly" mode where any
fail is nonzero).
- Consider
libtest-mimic-compatible output formats for tool familiarity.
