PersistentRestartLoopGuard
Defined in the protocols module.AI Agent A :class:
RestartLoopGuard whose events survive a process restart.
The in-memory guard is reconstructed fresh on every boot, so a persisted
turn that hard-crashes the whole process (OOM, segfault) can drive an
infinite supervisor → boot → auto-resume → crash loop the breaker never
sees. This subclass loads its event history from an injected
:class:RestartStoreProtocol at construction and flushes back on every
mutation, so the breaker observes the true cross-boot restart rate and can
trip on a crash cycle slower than a single in-process window.
The window defaults to one hour (vs. the in-process 60s) because a
cross-boot crash loop is paced by process (re)start latency, not by an
in-loop retry. Pure decision preserved: all persistence is delegated to the
injected store, so the trip logic remains provable in isolation.
