Question 1

Is this LangGraph?

Accepted Answer

ChorusGraph is a full replacement for LangGraph — not a wrapper, not a plugin, and not “LangGraph plus extras.” You install ChorusGraph directly (pip install chorusgraph) and run Graph + ChorusStack with built-in semantic cache, Route Ledger, and swappable ports. LangGraph appears only in our benchmark tables below as the baseline we measured against.

Question 2

Do I need a PrismRAG license?

Accepted Answer

Vector retrieval works without a license key. Taxonomy remap (advanced mapping) requires a PrismRAG license. Default zero-dep keyword retrieval needs no key.

Question 3

HIPAA / SOC2?

Accepted Answer

Controls are built into the runtime (Route Ledger, tenant isolation, audit replay). External third-party audit is Phase 2 — we do not claim certifications we have not earned.

Question 4

Postgres support?

Accepted Answer

SQLite ships in 1.0. Postgres HA is Phase 2 — stated honestly on this page and in ENTERPRISE_READINESS.md.

Question 5

How do I reproduce the benchmarks?

Accepted Answer

See docs/BENCHMARK_RESULTS.md and benchmark/results/azure_20260704_212111/. Run python -m benchmark.run_scenarios with the exact flags documented in BENCHMARK.md. HL1 healthcare single is a tie — we disclose it.

Question 6

What about the H10 latency numbers?

Accepted Answer

H10 repeat-band metrics (575 ms vs 4498 ms p50) are sliced — B includes cache and Cortex features A lacks. See benchmark/FAIRNESS_H9.md before quoting latency wins.
