- What is this?
- Raj Dholakia's hiring demo for NPX Innovation: a cited Q&A over 19 real CNSC REGDOCs and a CANDU shift-turnover generator over simulated Bruce Power data.
- Is the plant data real?
- No — simulated, tuned to CANDU-nominal parameters. None of it mirrors any actual Bruce Power reading.
- Is the REGDOC corpus real?
- Yes. 19 CNSC REGDOCs from cnsc-ccsn.gc.ca, chunked and embedded into Supabase pgvector. Every answer cites its source section.
- How many questions can I ask?
- Anon: 5/day. Signed in: 50/day. Industry domains (npxinnovation.ca, brucepower.com, opg.com, cnsc-ccsn.gc.ca, cameco.com, uwaterloo.ca): 100/day. Limits are tight because the demo runs on a personal OpenAI wallet.
- What happens if I ask something outside the corpus?
- One of two fallbacks — off-topic questions get a plain refusal, in-topic but uncovered questions get a low-confidence disclaimer. The assistant never guesses and never fabricates citations.
- Can I sign in?
- Yes — magic link to your email. Session cookies only. Your email is used to resolve rate-limit tier; never sent to OpenAI or logged against queries.
- Are my questions logged?
- Request metadata only (timestamp, route, latency, hashed IP, tier, similarity scores). Never the raw question or answer.
- What stack is this on?
- Next.js 16 + assistant-ui + Supabase pgvector + OpenAI + Upstash + Cloudflare Workers. Bun as the package manager.
- Is the code public?
- It will be once the Loom walkthrough is recorded.
- Who do I talk to about NPX Innovation?
- Visit npxai.com. This demo is a hiring application from a candidate, separate from NPX's own work.
