A node claiming something ran must cite a tool_call_id the host issued in
the trajectory. A citation absent from the trajectory is invented, so the
node is dropped along with its edges; a missing citation counts as invented
only when every real ID survived budget fitting, so a trimmed payload cannot
silently empty a graph. Judging is skipped where the evidence cannot be
enumerated: the process-detail supplement dumps raw event JSON and the
messages-table fallback carries no call IDs. Verified citations land in node
metadata rather than tool_execution_id, which is foreign-keyed to
tool_executions.
Also close two smaller holes: fact text can no longer carry the host index
delimiters, which would close the block early and spill the remaining index
into the system prompt; and the console fact endpoints reject the reserved
note/context-* prefix, matching the MCP tool layer.
