El SDK CI - dev / build-and-test (pull_request) Failing after 10m55s
No ingest path could carry a vector. engram_node/_full/_layered take text only, and a node acquired an embedding solely via engram_embed_backfill DERIVING one from n->content. That made text the mandatory entry medium: any non-text modality had to be described in prose first, so the geometry we then reasoned over was the geometry OF THE DESCRIPTION, not of the signal. Measured: POST /api/nodes accepted an "emb" field, returned 200 with a fresh id, and stored nothing — emb_dim=None, embedded=false. engram_node_set_emb attaches a vector to an existing node. Off-dimension vectors are stored but not indexed (the HNSW build loop already filters on emb_dim), so modality geometry is durable and addressable without perturbing the canonical index. Setting emb also makes the node ineligible for embed_backfill, so a realizer's vector is never overwritten by a text-derived one. Two reporting fixes ride along, because both are how the drop stayed invisible: the create response now reports emb_set instead of being success-shaped regardless, and the node document now always emits emb_dim and embedded — without which a genuine ingest drop and a mere reporting gap are indistinguishable. Verified live: voice node emb_dim=64 embedded=true; text control emb_dim=0 embedded=false; malformed hex, length mismatch and dim<=0 all reject. KNOWN PLACEMENT DEFECT: this is at the consumer. Ingest is a language concern, not an engram feature — every el program touching any modality needs it. The vector also marshals as a hex STRING because el has no first-class geometry value, which reintroduces text as the transport medium one layer below the problem being fixed. The durable shape is geometry as an el value plus declarable realizers, after which the engram stops having an ingest concept at all. Landing this as the verified probe that proves the path.
