Changelog

0.9.3 -- Connection-Error Notifications

  • laceNotifications now emits a default structured notification when a call fails with a connection-level error (DNS failure, connection refused, TLS error, etc.). These failures never reach assertion evaluation, so the existing scope and condition rules could not surface them.
  • The notification fires once on entry into the error state -- when the same call had no error on the previous run, or there is no previous run -- and stays silent while the error persists. Timeouts are unaffected; their existing rules still own that outcome.
  • Added conformance vectors covering the default error notification and its silent-on-repeat behaviour.

0.9.2 -- laceNotifications, laceEmitRecovery

  • Fixed laceNotifications silentOnRepeat default behavior
  • Extended laceNotifications tests to cover the silentOnRepeat functionality
  • Added laceEmitRecovery extension with test coverage

0.9.1 -- Body Saving Changes

  • Removed bodyPath from the request record schema; request bodies are no longer saved to disk (they are already present in the AST)
  • Added result.bodies.dir configuration option (default false) to control whether response body files are written
  • Added --save-body CLI flag to enable response body file writing for a single run
  • Body file path convention simplified to call_{index}_response.{ext}
