Package adkpath locates the Python ADK on the system it is running on.

Package budget derives the supervisor's start deadlines from one measured table (GAPI-DIV-107).

Package checkpoint dumps and restores process trees with CRIU (GOBLIN-DIV-018, research section 4.4/4.5).

Package logging is the one place log handlers are built.

Package mounts bootstraps the virtual filesystem hierarchy during Phase 0 of a PID-1 boot (GAPI-DIV-027), before cgroups or the event bus exist.

Package pid1 installs the explicit PID-1 signal semantics (GAPI-DIV-027).

Package procsig delivers signals to agent processes guarded by their start epoch (DDR-5, GAPI-DIV-016): a signal aimed at a dead process whose PID was recycled must never hit the new occupant.

Package product carries the identity of the product whose process the kernel is running inside.

Package shutdown is the PID-1 teardown executor (GAPI-DIV-027): a correct init shutdown is StopAll -> sync -> reverse umount -> reboot(2), replacing the naive grace + SIGKILL pattern.

Package subreaper implements the PID-1 orphan-reaping obligation (GAPI-DIV-027): the supervisor registers as a child subreaper so orphaned descendants reparent to it instead of pid 1, and a reap loop collects their exit statuses - zombie accumulation is a kernel obligation, not an optimization.

Package watchdog keeps a hardware (or software) watchdog timer fed (GAPI-DIV-027): if the supervisor hangs, the kicks stop and the device resets the machine.
