lakehouse/mcp-server/samples/staffing_roster_sample.csv
root 23eb04a145 Onboarding wizard — ingest any staffing CSV in 3 steps 
New /onboard page. Client-facing wizard for getting real data into
the system without engineering help.

Flow:
1. Drop a CSV (or click 'Use the sample as my data' — ships a 25-row
   realistic staffing roster under /samples/staffing_roster_sample.csv)
2. Browser parses client-side. Columns auto-typed (text/int/decimal/
   date). PII flagged by name hint AND content regex (emails, phones).
   First rows previewed. Read-only — nothing written yet.
3. Name the dataset (lowercase+underscores). Commit.
4. Post-commit: dataset is live. Shows 4 next steps the operator can
   take (SQL query, vector index, dashboard search, playbook training).

Backend:
- /onboard serves onboard.html
- /samples/*.csv serves CSV files from mcp-server/samples/ with
  filename validation (only [a-zA-Z0-9_-.]+.csv, prevents path traversal)
- /onboard/ingest forwards multipart/form-data to gateway /ingest/file
  preserving the boundary. The generic /api/* passthrough breaks
  multipart because it reads as text and forwards as JSON; this route
  uses arrayBuffer + original Content-Type.

Verified end-to-end: upload sample roster (25 rows, 12 columns) →
parse in browser → show columns + PII flags + preview → commit →
gateway writes Parquet, registers in catalog → immediately queryable:
  SELECT * FROM onboard_demo2 LIMIT 3

Round-trip <1 second.

Nav updated on all pages to link Onboard. Shipped with a sample CSV
so the full flow is demonstrable without real client data.

When a real client shows up, same path — they upload their CSV.
No engineering ticket, no code change, no schema pre-definition.

Security: sample filename regex prevents path traversal. CSV parse
is client-side pure JS (no DOM injection). Commit uses existing
/ingest/file validation (schema fingerprint, PII server-side,
content-hash dedup).
