How this week was reconstructed

Both relevant Claude Code sessions and Git history were recovered for this period. Large delegated families were grouped only when their parent lineage was explicit.

We audited the available Claude Code main sessions, their proven child lineages, and the repository history. Session notes explain intent and investigation; Git remains the authority for code that actually landed.
