Phase 1.0AF: offline BigApp lifecycle model
Status: HOST_LIFECYCLE_MODEL_COMPLETE_TARGET_IMPLEMENTATION_BLOCKED
Date: 2026-07-29
The host-only state machine implements the lifecycle selected in Phase 1.0AE using exact built-in fake events. It contains no PS5 headers, process calls, syscalls, socket, real clock, CLI or filesystem output.
The model refuses launch when a BigApp already exists. A successful synthetic
attempt must attach and arm the parent, request only fixed title PPSA01659,
observe one positive unique child identity, detach the parent, observe child
exec, replace one exact payload, restore temporary mutations, detach the child
and emit one result within 64 supplied ticks.
Failure injection proves the modeled unwind order. An acquired parent is detached. A newly observed child is the only process eligible for termination. If replacement began, restoration precedes termination. Cleanup failure is a hard error rather than a clean result. These are properties of the model, not firmware or runtime evidence.
Target implementation remains blocked. The next permitted work is a host-only bounded ELF contract and validator so malformed or oversized payloads can be rejected before any future launcher boundary.
