runner-smoke

Deterministic smoke harness that asserts runner invariants (session continuity, tenant isolation, and state writes) using canned dev-mode traces in cases/. The harness ensures we catch regressions before wiring it to the real Runner process.

Run it via make runner.smoke, or directly with cargo run -p runner-smoke -- --cases <dir> when pointing at alternative trace folders.

Effect Log Schema

effect_log.schema.json describes the once-only effect log contract (trace IDs, sequence, and event types). The harness ensures every state_write event carries a unique trace_id; any duplicate trace detected across sessions fails the smoke suite to guard idempotent state writes.
