A native graph provider can load its relationship COUNT (manifest) on a cold open
but fail to load the source→target adjacency itself (observed on mmap-filesystem:
the SSTable-segment load is swallowed). The result is find({ connected }),
neighbors(), and related() silently returning [] despite persisted edges — and
staying empty after warm-up. Because it is [] not an error, callers cannot tell
real data is missing.
Brainy now runs a one-time consistency check on the first graph read: if the index
reports relationships exist but a known persisted edge's source resolves to no
neighbors, force a rebuild from storage (which re-scans + repopulates the adjacency);
if even that cannot read the edge, throw the new GraphIndexNotReadyError instead of
serving [] as truth. O(1) probe (one verb + one neighbor lookup), cached per brain,
and a no-op once the adjacency is live — so it self-heals the cold-open case and is
loud when it genuinely can't.
Wired into neighbors() + getRelations() (the graph-read primitives behind
find({ connected })). The underlying cold-open load is a native-provider concern
(addressed upstream); this makes the failure self-healing + loud rather than silent.
Tests: tests/unit/brainy/graph-adjacency-cold-load.test.ts (live → no-op; broken →
rebuild; unfixable → throws; size 0 / no edges → no-op; transient failure → re-checks
without breaking the query). Full unit gate green (1531/1531).
