- Add safeReadRail/safeWriteRail helpers with try/catch for private browsing - Initialize railExpanded with lazy useState: safeReadRail() ?? isHITLRunning - Wrap setRailExpanded to persist every change to localStorage - On card-identity change: restore from localStorage instead of resetting to isHITLRunning - On HITL flip-on: persist forced-expand to localStorage via safeWriteRail(true) - Update web/CLAUDE.md localStorage allowlist with contextmatrix-rail-expanded key
