Task: Complete the reporting diagrams and write the audit record

Close H01: the three part diagrams carry the sentinel and an empty manual section, the root diagram has no two-pass structure, and no Component Architecture Audit record for the component exists.

• No class whose code has methods is drawn as an empty box, and every drawn edge is supported by the code.
• The root diagram follows the two-pass contract and its rendered image is read, not merely regenerated.
• The audit record is written and H01 passes.

(Implementation strategy. Written when work starts; key decisions are distilled into the parent story's * Decisions at close, but the plan itself stays — it is the historical record of what we did.)
