pub fn external_property_snapshot() -> HashMap<PropertyKey, PropertyValue>Expand description
Snapshot the cells currently visible to the external bus by polling the
channel non-destructively. Used by FFI typed reads that want to consult
pending pre-run writes without owning a PropertyStore. The returned
map is empty when the channel is unset or empty.
This is a best-effort accessor - concurrent senders may add entries after the snapshot returns. Read consistency across a single FFI call is sufficient for round-trip embedder scenarios (set N, read N).
