/**
 * Claude's SessionStart source decides where a virgin event WAL begins reading its transcript.
 *
 * A positional startup prompt is written before SessionStart reaches the connector. Generic JSONL
 * adoption therefore parks after the only record that can open the first run, and every later
 * assistant/tool record maps to nothing. Only `source: "startup"` names a genuinely new session;
 * resume, fork, clear and compact all point at retained history and must keep ordinary adopt-at-end
 * semantics.
