"""Per-slot watchdog store for safety-sell (REQ-034 / BAT-010).
|
|
|
|
WatchdogStore tracks the last time a snapshot RPC response included each
|
|
holding slot. BAT-011 trigger loops use is_expired() to decide whether a
|
|
slot is unmonitored (strategy module absent) and therefore eligible for
|
|
autonomous safety-sell actions.
|
|
|
|
Thread-safety: dict reads and writes in CPython are GIL-atomic for simple
|
|
assignments, which is sufficient here — one writer (snapshot-rpc thread)
|
|
and one or more readers (BAT-011 trigger-loop threads). No explicit lock
|
|
is needed.
