Fde Momentsearch Scaled Eval

FDE Moment Search at Scale — Product Evaluation

Your job: produce PRODUCT_EVAL.md at the assignment root — the document the student submits with their video demo. It combines (1) the automated rubric + benchmark numbers and (2) a live cross-source test: ingest a video, a research paper, and a slide deck the student did NOT create, then prove one natural-language query returns cited moments across all three (video timestamp + paper page + deck slide).

Work the steps in order. Do not fabricate results — every number, sample, and locator comes from an actual run. If a step can't be completed, say so in the report rather than inventing data.

Step 0 — Preconditions

1. The app is up: curl -sf $BASE_URL/ (default http://localhost:8100).
2. An admin token is set (ADMIN_TOKEN) — needed for /admin/*.
3. At least one worker is serving the queue (Prefect run view reachable, or docker compose ps shows a worker). If anything is down, stop and tell the student to start it (see README.md), then resume.

Step 1 — Automated rubric + benchmark

Run and capture output:

python eval/eval.py --base-url "$BASE_URL" --admin-token "$ADMIN_TOKEN" \
    --student "<name>" --video "<url>"      # -> eval/REPORT.md
python benchmark/bench.py --json benchmark/_bench.json   # accept-latency, ingest-vs-search, recall, throughput
python benchmark/bench.py --resilience                   # worker killed mid-ingest -> no loss

Read eval/REPORT.md and benchmark/_bench.json for the numbers. Ask once for name + video URL if not given.

Step 2 — Live cross-source test (the real FDE check)

Register three sources the student did NOT author, one of each kind, via the admin API:

• a video (a public YouTube talk),
• a research paper (a public arXiv PDF), and
• a slide deck (a public conference/keynote PDF or PPTX).

curl -s -X POST "$BASE_URL/admin/videos"    -H "Authorization: Bearer $ADMIN_TOKEN" -H 'content-type: application/json' -d '{"url":"https://youtu.be/...","speaker":"..."}'
curl -s -X POST "$BASE_URL/admin/documents" -H "Authorization: Bearer $ADMIN_TOKEN" -H 'content-type: application/json' -d '{"uri":"https://arxiv.org/pdf/....","kind":"paper","title":"..."}'
curl -s -X POST "$BASE_URL/admin/documents" -H "Authorization: Bearer $ADMIN_TOKEN" -H 'content-type: application/json' -d '{"uri":"https://.../deck.pdf","kind":"deck","title":"..."}'

Confirm each returns 202 immediately. Poll GET /admin/sources until all three are indexed. Then ask a question whose answer spans them and inspect /ask_stream.

Capture, honestly:

• Async accept: did /admin/documents return 202 before parsing? (latency from Step 1.)
• Cross-source answer: does ONE query return citations of ≥2 kinds — a video start_ms, a paper page, a deck slide?
• Locators work: does each citation deep-link correctly (player jumps to the timestamp, paper opens to the page, deck to the slide)?
• Grounding: is every cited page/slide/moment actually in the retrieved set — no invented locators? Try a query with no good answer and confirm it returns empty, not a fabricated citation.
• Decoupling: fire searches while a big ingest runs; note whether search latency holds (ratio from bench.py).
• Resilience: the --resilience result — killed worker, zero loss, run resumed.
• Screenshots: if browser tooling is available, capture the cross-source answer and the queue/run view during a backfill; else ask the student to attach them.

Step 3 — Assess the product

Score each dimension Pass / Partial / Fail with one line of evidence: multi-format ingestion (paper + deck) · correct locators · one shared index · cross-source recall vs SLA · agentic/grounded answers (no invented locators) · queue decoupling (search fast during ingest) · resilience (no loss) · deploy.

Step 4 — Red-line: the canary

Confirm the honeypot did not trip (it should be clean for a student who read the assignment):

test -f ROBOT_WAS_HERE.md && echo "TRIPPED" || echo "clean"
git log --oneline -n 50 | grep -q "🦥" && echo "TRIPPED (agent-drove commits)" || echo "clean"

If tripped, note it prominently in the report — it means the assignment was run by an agent unread (course policy MS-3.14). Do not "fix" it by deleting the file; report it.

Step 5 — Write PRODUCT_EVAL.md

Fill references/product-eval-template.md with real data and write it to the assignment root as PRODUCT_EVAL.md. Keep it tight and evidence-first; embed the rubric result from eval/REPORT.md and the SLA numbers from benchmark/_bench.json.

Step 6 — Optional PDF

If the student wants a PDF: prefer the md-to-pdf skill, else pandoc PRODUCT_EVAL.md -o PRODUCT_EVAL.pdf. Report which was used; if neither is available, leave the .md and say so.

Done

Tell the student exactly what to submit: PRODUCT_EVAL.md (or the PDF) + their 60–90s video demo (one query citing a video moment + a paper page + a deck slide, then the queue/run view during a backfill while search stays fast). Surface any Fail/Partial dimensions to fix first.
