CrashLab · v0.50.0

Test the failure modes that create duplicate or ambiguous effects

Package availability boundary: commands that use published @ruleoak/*@0.50.0 packages apply only after those exact npm packages are publicly available. The fresh GitHub v0.50.0 source repository remains the canonical source release.

CrashLab exercises bounded scenarios such as timeout before/after effect, response loss, partial effects, duplicate retry, revocation during retry, expiry, concurrent races and stale state.

Run one scenario

npx @ruleoak/cli@0.50.0 crashlab run --scenario scenario.json

Build a scorecard

npx @ruleoak/cli@0.50.0 crashlab scorecard --scenario-dir scenarios --format human
# CI formats are also available: json, junit, sarif

What a scorecard can establish

behavior against the declared scenario contract
retry/duplicate-effect invariants
evidence completeness for exercised paths
revocation, concurrency and stale-state behavior for the fixture

It does not prove universal production fitness.
