• Add priskv_publish_node_with_pin(kv, keynode, pin_on_publish) and make priskv_publish_node delegate to it. Publishing now runs under the hash-bucket lock, inherits pin_count from the old version, removes the old visible node, inserts the new one, and cleans up the old outside the lock—ensuring a single visible version. • Replace deprecated priskv_key_pin with priskv_key_pin_latest; update semantics so both pin and unpin operate on the latest visible version under the bucket lock, with inline expiry cleanup on miss/expired. • Transport SEAL now calls priskv_publish_node_with_pin to remove the publish→pin race; ACQUIRE uses priskv_key_pin_latest; RELEASE uses priskv_key_unpin_latest. • Add concurrency tests (two-thread and stress) to verify single-version visibility and pin_count inheritance; extend negative/permission and failure-path coverage.
