Supporting materials for From test purposes to verdicts: source analysis and a controlled case in MQTT test software

Supporting materials for the manuscript “From test purposes to verdicts: source analysis and a controlled case in MQTT test software.” Resources 1–3 are unchanged from version 1.0.0. Resource 4 preserves the previous controlled-case resource byte-for-byte and adds source-archive provenance, a configurable replay helper, and separate same-host relocation QA records. The four resources contain a source-witness guide; selected historical fields and 15 fixed synthetic logic scenarios; a 17-purpose public MQTT test-source inventory with cross-case maps; and one controlled Mosquitto test-to-runner case. Read README_RELEASE.md and RIGHTS.md first. The same-host QA does not expand the manuscript sample, authenticate historical executions, establish cross-platform robustness, or constitute independent replication. Earlier preparation-state labels describe original creation states; the release notices supply current access and component-specific licence information without rewriting evidence. These materials do not recreate the complete historical archive or IoT-Testware suite, establish native product defects or prevalence, or turn retries into independent samples. No full manuscript, full standards, credentials, external dependencies or executable binaries are included. Original author documentation and data are CC BY 4.0; original standalone author code is MIT. Included IoT-Testware source retains EPL-1.0; Mosquitto source and adaptations retain their supplied EPL-2.0 OR BSD-3-Clause terms. These licences apply by component, not as blanket relicensing.
