Security Record

Hours = wall-clock session duration per agent, summed; not gap-summed active time. Dev comments = msubbu-logos on GitHub (overwhelmingly Bob replying to Codex threads). Guard/holds data reflects today's session only. LOC excludes lockfiles, *.dar, and dist/. Pre-fleet days (May 20–Jun 3) show · for hours/prompts; Claude sessions began Jun 4. "Madhu" hours are sessions run from the home directory before dedicated agent workspaces existed.
