- mkbootimg.mk: boot.img uses the normal ramdisk again; the recovery.img rule is guarded so it only builds when recovery is enabled (PAWLET_BUILD_RECOVERY=1) and carries the recovery ramdisk. - config.txt [tryboot] back to boot_partition=2 (A/B trial); recovery enters via reboot,3. - vendor.prop reboot reason back to reboot,tryboot. - drop the no-op reserved-size lines (AOSP ignores RESERVED_SIZE for fixed non-dynamic partitions).
