What
Direct process.env reads were replaced with typed registry lookups across roughly 220 sites, covering CLAUDE_MEMORY_STORES, CLAUDE_PROJECT_UUID, ANTHROPIC_BASE_URL, CLAUDE_JOB_DIR, TERM_PROGRAM, BAT_THEME, PATHEXT, terminal multiplexer detection and more. Parsing and trimming now happen once in the registry, so MCP_OAUTH_CALLBACK_PORT is checked only against the 65535 upper bound, its lower bound of 1 being enforced by its declaration.
