[fusa-qual-wg] Add TPL-004 / tool qualification report template

[uwendi]

Summary

Add LLVM-QUAL-TPL-004, a Tool Qualification Report template, together with three associated guidance documents.

TPL-004 records the execution and results of qualification activities planned in TPL-002 (#48), following the classification and malfunction analysis documented in TPL-003 (#57). It assumes that the activities follow one referenced TPL-002 revision. If the plan or classification basis changes, TPL-002 and, where relevant, TPL-003 should be updated before completing the qualification report.

The guidance is divided into:

• a central guide explaining the workflow boundary and how to complete the report
• a qualification-approaches companion covering validation, confidence from use, development-process evaluation, output verification, certification, and evidence reuse
• a standards companion comparing the relevant concepts and test-coverage expectations across IEC 61508, EN 50716, ISO 26262, IEC 62304, and DO-178C/DO-330

Design considerations

The template is intentionally shorter than the accompanying guidance. It references the qualification strategy already established in TPL-002 instead of repeating it.

The guidance also:

• distinguishes qualification approaches from evidence sources and supporting controls
• explains how upstream open-source evidence and downstream evidence can make complementary contributions
• separates requirements and behavior coverage from structural coverage of the tool implementation
• explains certification and its relationship with qualification
• supports standard-specific conclusions without treating the standards as interchangeable
• uses more accessible wording for concepts such as issues, findings, anomalies, and anomalous operating conditions

The documents are informative and do not replace the applicable standards, regulatory or certification guidance, or organization-specific processes.

Feedback is very welcome, particularly on the usability of the template and whether the guide structure makes the detailed material sufficiently approachable.
