Tenant recall: VSEARCH, VSIM, VFUSE New
The recall surface an agent actually issues is now on the wire, in the playground, and on this site.
VSEARCH — caller vector, cosine over that tenant’s HNSW. Trailing MIN_SCORE, EF, SPACE.
VSIM — neighbors of a stored id, self excluded. “More like this memory” without re-embedding.
VFUSE — late fusion across named SPACE graphs with caller WEIGHTS. Missing ids score 0.
Embeddings stay with the caller. DBX does not run CLIP or MiniLM. A named space is another mmap/HNSW file in the same tenant directory — backup, quota, and shred still hit one customer. Certified ANN p50 on the published profile is 2.304 ms, not sub-millisecond. This is not a Qdrant competitor.
Linux strict seals each tenant as its own process: Landlock-restricted filesystem, encrypted WAL / checkpoints / vector ids / HNSW graph, Unix sockets only the orchestrator can open. Idle RSS in the 14–17 MiB band.
Honest limits: SQ8 .vec rows stay mmap plaintext so idle tenants live in page cache. Put the data dir on LUKS or fscrypt. make run-dev is still inprocess — do not ship that as Isolation Kernel. We are not SOC 2 certified.
A recorded demo of the public site and the dashboard compiled into dbx-orchestrator: login, provision, mint a writer, console SET/GET/VADD, explorer, backup. Engineer voiceover over a 140 BPM tech bed. The dashboard itself is not on GitHub Pages.
