Claude Code auto-loads CLAUDE.md (uppercase) at startup. On macOS/Windows
(case-insensitive FS), claude.md resolves fine. On Linux (ext4/btrfs),
it's a different file and never gets loaded — meaning all project
directives, delegation rules, and context recovery instructions were
silently missing on this workstation. This explains the behavioral
differences vs the Mac.
