Valgrind_Parser

Use when editing, regenerating, or interpreting any of the project's spec documents (PVD, SDD, HLRs, LLRs, Test Plan, Traceability) or their generator inputs. doc/Project.xml is the SINGLE SOURCE OF TRUTH for the project's design, requirements, and verification — and the canonical store from which traceability (SDD→HLR→LLR→Test) is measured. doc/PVD.md is the hand-authored Product Vision Document that sits above the generated stack; the AI is expected to draft and fill in PVD content under the developer's direction, asking targeted questions when sections are thin or missing. USE FOR: any change to doc/PVD.md, doc/SDD.md, doc/HLRs.md, doc/LLRs.md, doc/STP.md, doc/Traceability.md; drafting or revising the Product Vision Document; adding/removing/renumbering HLRs or LLRs; adding new tests under test/ that need traceability annotations; updating Project.xml schema; authoring new Jinja2 templates under tools/templates/; running tools/render_doc.py. DO NOT USE FOR: edits to source code under src/ that do not chang
