nx_root_trace.nx -- THE ROOT-TRACE INSTRUMENT (Genealogist SIL metric), operator 2026-06-13: "make sure that we can go from spore up emitting all of our shapes that have gotten us to where we are." The no-floating LADDER (nx_capability_ladder) already proves every QUEUE row rests on a DONE foundation. This is its GENEALOGY twin: it walks lineage.tsv's child<-parents edges and proves every ORGAN traces UP, by an unbroken parent chain, to the SPORE -- the genesis node rv64im_min_sim (BOOTSTRAP_MAP "god"). A node that CANNOT reach the spore is the genealogical equivalent of a floating capability: FLOATING-ROOT = parents "-" but the node is NOT the spore (claims no parent, yet isn't god) BROKEN-LINK = a named parent has NO row in the tree (a dangling ancestor) UNROOTED = all parents present but at least one does not itself reach the spore Drives traced -> nodes, broken_links -> 0, floating_roots -> 1 (only the spore). Mechanism mirrors the proven capability-ladder fixpoint, but over the lineage parents column instead of the queue deps column (DRY of idiom, not of code -- the formats differ). SELF-VALIDATING (no false-green): a baked pos control (child of the spore traces) and a neg control (a non-spore "-" root + a child of an absent spore stays untraced) run on a synthetic in-memory tree BEFORE the real lineage.tsv; controls wrong -> RED, exit 1. Sovereign: raw syscalls, no shell/sed/awk, no third-party. license_tier: ORIGINAL
