+# Prospect Platform API MVP
+
+Dependency-light JSON API for a single demo tenant (`demo-tenant`). Core domain rules use only Python's standard library; persistence is SQLite. This MVP stores prospect evidence and scores, but never sends outreach.
+
+## Run
+
+From this directory:
+
+```bash
+python3 app/main.py
+# listens on http://127.0.0.1:8000
+python3 -m unittest discover
+```
+
+Set `PROSPECT_API_PORT` or pass `--port`; set `PROSPECT_API_DB` or pass `--db` to override the default `prospects.db`.
+
+## Endpoints
+
+- `GET /api/v1/health/live` — liveness.
+- `GET /api/v1/dashboard/summary` — tenant-scoped counts and score average.
+- `GET /api/v1/businesses` — list businesses; optional `?q=` filter.
+- `POST /api/v1/businesses` — create a business from JSON (`name` required; website, email, phone, description optional). Normalization, scoring, deduplication, and suppression are enforced server-side.
+- `GET /api/v1/businesses/{id}` — retrieve one tenant-scoped business.
+- `POST /api/v1/suppressions` — add `{kind: email|domain|phone, value: ...}`. Future matching business creation is blocked.
+- `POST /api/v1/imports/preview` — preview `{rows: [...]}` without writing; reports accepted, duplicates, suppressed, normalized rows.
+
+All SQL uses parameters and all responses are JSON. Scores include `score_version` and `score_factors` for traceability. There is intentionally no send/outreach endpoint.

+# ProspectOS web MVP
+
+Self-contained static frontend for the Prospect Platform API. There is no bundler or runtime dependency: serve this directory with any static HTTP server.
+
+## Configure and run
+
+The API base is configurable before `app.js` runs:
+
+```html
+<script>window.API_BASE = 'http://127.0.0.1:8000';</script>
+<script src="app.js"></script>
+```
+
+If not set, the UI uses `localStorage.prospect_api_base` when present, then renders clearly-labelled demo data. The API contract used by this page is the current MVP contract:
+
+- `GET /api/v1/businesses` (optional filtering is performed client-side)
+- `GET /api/v1/dashboard/summary`
+- `POST /api/v1/businesses`
+
+The CSV control is intentionally preview-only. The backend's `POST /api/v1/imports/preview` can be wired to a confirmation flow later; this UI does not claim that import rows have been persisted.
+
+## Browser verification
+
+1. Start the API from `apps/api` with `python3 app/main.py`.
+2. Serve this directory: `python3 -m http.server 8080 --directory apps/web`.
+3. Open `http://127.0.0.1:8080`, with `window.API_BASE` set to `http://127.0.0.1:8000` using a tiny pre-load edit or browser devtools.
+4. Confirm the header changes to **API connected**, metrics populate, search and score/status filters update the table, selecting a row opens evidence/confidence/freshness, and adding a prospect POSTs to `/api/v1/businesses`.
+5. Confirm rows with `status: review` show **Outreach unavailable — Review this prospect before outreach is available**, and suppressed rows show **Outreach unavailable — Suppressed records cannot be contacted**. There is no outreach/send endpoint or button.
+6. Select a CSV and confirm a local, preview-only table appears without a network request.
+7. Resize below 700px to verify the collapsible nav, stacked panels, and horizontally scrollable explorer table.
+
+A zero-dependency static smoke page (`smoke-test.html`) checks the key DOM contract in an iframe and reports pass/fail.
