On a cold process start of a large brain (above the eager index-rebuild
threshold), a native graph adjacency can report size()>0 — its membership set
reloaded — while the source->target edges did NOT load, so find({connected}),
neighbors() and related() returned [] for edges that are persisted on disk. A
database returning empty for data that exists, based purely on warm/cold state,
is a correctness bug; it hit a production deployment after every deploy.
Refactor the cold-load guard into verifyGraphAdjacencyLive(), which gates its
heal/throw decision on a GLOBAL known-edge sample (a persisted verb's source,
which by definition has an outgoing edge) rather than the queried anchor: a
stale adjacency is rebuilt from storage, an unrecoverable one throws
GraphIndexNotReadyError instead of serving [], and a genuinely edgeless anchor
still returns [] with no spurious rebuild. executeGraphSearch re-verifies before
trusting an empty connected result and re-collects after a heal. Adds a 5-case
integration test (self-heal / loud-throw / edgeless-no-false-positive / healthy
/ re-collect) plus updated unit coverage.
