Finality pause and /api/live pinned to the node's landed shape (ca3-v4-0316 b2e21447, eec34ac3): finalityActive decides paused when present, the node's "paused: " prefix dropped from the sentence, heldBy not repeated when the reason names the table, timestamp_source header | chain_block, a null vote_key_hash reads as empty; tests on the node's exact words
