+Current Topics & Backlog for Qualification Group
+================================================
+
+This document serves as the central hub for our working group's current
+activities, including ongoing discussions, key challenges, and our 
+prioritized backlog.
+
+This is a living document and will be updated as our work evolves.

+
+Ongoing Discussions
+===================
+
+This section outlines topics the working group is currently analyzing or
+deliberating on.
+
+* **Compiler Qualification Language & Standard:**
+    * **Topic:** Defining the initial scope for Clang qualification.
+    * **Challenge:** Deciding between C and C++ for the first qualification target.
+    * **Sub-topics:**
+        * Which C standard (e.g., C11, C23) is most suitable?
+        * Creating an open-source conformance test suite for C seems unfeasible. Any alternatives? Is this a requirement?
+        * Would it suffice to do testing using Alive2?
+        * Criteria for deciding the hardware architecture (target)
+        * Criteria for deciding specific compiler use case and options enabled
+        * Qualification standards usually require a specific, frozen tool version and a controlled development process to be qualified for a particular use case. The continuous development model of most open-source projects doesn't align well with this requirement. Would it be possible to have a Long Term Support (LTS) release of LLVM?
+
+* **Qualification Standard and Tool Confidence Level:**
+    * **Topic:** Defining the initial safety framework scope for qualification (ISO26262, IEC61508, etc).
+    * **Challenge:** We need enough members for each framework we want to include in scope.
+    * **Sub-topics:**
+        * Shall we initially focus on a specific standard, or provide templates for different standards so members can work on their own implementations?
+        * Criteria for choosing tool confidence level
+
+* **Toolchain Integration with Open Source Tools:**
+    * **Topic:** Investigating how to demonstrate confidence in LLVM's development process.
+    * **Challenge:** Bridging the gap between traditional safety-critical processes and open-source development models.
+    * **Sub-topics:**
+        * Can we leverage existing test suites?
+        * Identifying a path to continuous validation within a CI/CD pipeline.
+        * Integrating Alive2 tests
+        * Integrating a human centric approach (tests and documentation of the LLVM's development process)

+
+Prioritized Backlog
+===================
+
+This is a list of tasks and topics we have agreed to address in the near future, ranked by priority.
+
+1.  **Define Language & Standard for Qualification:** Finalize the decision on whether to qualify a specific version of the C or C++ standard.
+2.  **Research C Conformance Test Suites:** Identify and evaluate existing open-source or commercial C conformance test suites.
+3.  **Propose a Community RFC:** Draft a Request for Comments (RFC) to the LLVM community to formalize our group's goals and request support.
+4.  **Create a Public Wiki:** Establish a public-facing wiki or documentation site to track our progress and share findings.
+

+
+Future Ideas & Unsorted Topics
+===============================
+
+This section is a parking lot for new ideas or topics that have been raised but are not yet being actively discussed or prioritized.
+
+* Investigating qualification for the LLVM linker (lld).
+* Exploring the use of static analysis tools (e.g., clang-tidy, Malleus) in a safety-critical context.
+* Documenting the process for a minimal, safety-critical build of Clang.
