Set release boundaries for the tenant pgvector index

Operational risks for the tenant-filtered pgvector FAQ index center on SQL injection via query text concatenated into the vector search, plus the earlier failure mode (missing tenant filter in SQL, or querying a stale index version silently). Safety lives in executable gates, allowlists, redaction, and a named owner—not in a warning paragraph under an unsafe function.

user_q="hours'; DROP TABLE chunks;--" params_only=True print({'user_q_in_sql_string':False,'parameterized':params_only})

Expected evidence: **parameterized True**. A failed assertion means stop, investigate, and do not publish the tenant pgvector index.

Name who can disable the feature, what data is retained, and how to roll back to the last known good artifact. Pin the reviewed configuration (versions, thresholds, allowlists) so “what shipped” is reconstructable for vector-db-lab.

Write the release blocker as a predicate, not a feeling: “Do not ship the tenant pgvector index if SQL injection via query text concatenated into the vector search.” Pair it with a passing control that shows the reviewed configuration still works for two tenants with overlapping vocabulary FAQ chunks. Name an owner and a rollback handle (git tag, docs_version, previous image).

Security pages must not paste the happy-path demo. If your gate code looks like the implementation page, replace it with a deny/allow check aimed at SQL injection via query text concatenated into the vector search.

State the data retention rule in one line (what is stored, for how long, who can read it). Then state the kill switch (env flag, config pin, or feature owner). The tenant pgvector index is not shippable without both, even when tenant isolation test (0 cross-tenant hits); version pin echoed in response looks healthy.

At the safety and operations stage for vector-db-lab, the job is narrower than finishing a product demo. You are creating one progressive evidence piece about two tenants with overlapping vocabulary FAQ chunks that later pages inherit without redefining success. Keep that fixture small enough to inspect by hand, keep outputs copy-pasteable as text, and refuse to narrate this baseline as if it were a production SLA: in-memory cosine search on the same fixtures.

For this page specifically, success looks like an executable deny gate for the lab-specific threat while still centering the user decision to replace an in-memory list with a versioned vector index that cannot leak across tenants. If you cannot point to a file, command, or assertion that proves that for the tenant pgvector index, stay on this page instead of advancing.
