constrained_env combines three conditions: scheduler not running, in ISR, or cache disabled. Only the first is safe for flash access. Check xPortInIsrContext() (IRAM-resident) explicitly: - In ISR: output tag only via esp_rom_printf (ROM). Flash may be inaccessible. This matches V1 behavior where ISR logging was best-effort. - Not in ISR (scheduler not running, PHY init): call flash-resident esp_log_format_early_ which formats the full message. This ensures the override is safe for all constrained env cases without pulling in esp_rom_vprintf (1.2KB IRAM).
