# Vessels — Investor Walkthrough Script A 9-step demo that walks an investor through the Vessels artifact in ~12 minutes. Every step references a real route, a real persisted table, and (where relevant) a Λ-receipt hash you can verify on screen. Pre-flight (do once before the room): - `pnpm --filter @workspace/api-server seed:vessels:investor` plants one vessel with a sanctions hit, one anomaly above 0.7, one overdue maintenance item, and 90 days of risk-score history. - Confirm the api-server, the vessels web artifact, and the a11oy artifact are all green in workflows. - `pnpm dev` against `artifacts/vessels`. The script assumes the operator dashboard (`/dashboard`). --- ## 1. Landing & Command Overview (90s) Open `/vessels/`. Read the one-line thesis aloud: *"Vessels is the operator surface for ocean-going risk — sanctions, anomalies, voyage economics — with a receipt for every decision."* Click **Enter platform**. Land on the Command Overview (`/dashboard`). Lead with "this is what a maritime risk operator sees at 06:00 UTC." Point at the KPI strip — fleet count, open exceptions, sanctions exposure, average Λ. Numbers come from `/api/vessels` and `/api/vessels/formula/risk-history/*`. Investor takeaway: this is operational, not marketing. Every number on this screen has a receipt. ## 2. Fleet List & Behavioural Risk Scoring (90s) Sort by composite Λ risk descending. Top row is `MV TAMAR EXPRESS` (seeded). Click into it or navigate to `/risk-scoring`. Show the radar — six axes, one accent. Pick the top-risk vessel (Λ ≈ 0.9). Click **Show the math**. The Sheet opens, expression renders verbatim: ``` Λ = clamp( severity · likelihood · valueAtRisk / cap , 0, 1 ) ``` Point at the Λ-receipt hash in the footer. Tagline: **"the formula is the product, not the chart."** ## 3. Vessel Detail & 90-day Λ history (60s) KPI strip shows IMO, MMSI, vessel type, current lat/lng, current speed, heading. All values render in tabular-num monospace and pull live from the API — no placeholders. The line chart pulls from `vessels_risk_history` (table) via `/api/vessels/formula/risk-history/:vesselId`. The chart renders real numerics on first paint. Investor takeaway: every number on the page is a real number from a real persisted table. Each row carries the receipt hash that produced it. ## 4. Run a live recompute (60s) Click the **Show the math** affordance next to the composite number. The Λ weighted geometric mean expands inline with the live inputs, the weights, and the receipt ID of the most recent compute. POST `/api/vessels/formula/risk-recompute` from the in-page **Recompute now** button. The composite ticks (400ms ease), the 90-day trend line gains a new point, and a new row appears in the page-footer receipt strip. Investor takeaway: the math is auditable in-page and every compute emits a receipt. ## 5. Route Anomaly Engine & A11oy Handoff (1.5m) Click the **Anomalies** tab or navigate to `/route-anomaly-engine`. SSE feed renders the seeded anomaly at the top with severity 0.82, type `route_deviation`. Click it. Evidence panel populates with the AIS track that triggered the detection. Show the `// AMARU_HOOK: third_eye_pattern` marker in the developer-tools view — this is the attach point for the brain runtime. Note the **A11oy handoff ID** chip — every anomaly above the 0.7 threshold fires `crossProductHandoff` and the ID is persisted in the `vessels_anomaly_detections` table next to the receipt hash. Tagline: **"the moment a detection clears 0.7, it's no longer just Vessels' problem — it's an A11oy workcell."** ## 6. Open A11oy workcell — cross-product handoff (1m) Click **Open A11oy workcell**. The page hands off to the A11oy artifact with the anomaly context as the payload. A workcell appears with the maritime-routing template. Navigate back to Vessels. The **Recent A11oy decisions** panel on the Vessel Detail page now lists the workcell with a link back into A11oy. Investor takeaway: the platform is one fabric, not a folder of disjoint apps. ## 7. Voyage Calculator + Monte Carlo (120s) Navigate to `/voyage-calculator`. Pick VLCC + Ras Tanura → Rotterdam. Submit. Show the deterministic P&L (revenue, costs, TCE, break-even freight). Then click **Run Monte Carlo (2,000 iterations)** — calls `/api/vessels/formula/voyage-monte-carlo`. p10 / p50 / p90 land on screen. Click **Show the math** on the p50 — Sheet renders the Gaussian sampling formula. The calculation lands in `vessels_voyage_calculations` with its receipt. ## 8. Bunkering & Sanctions Screening (1.5m) Navigate to `/bunkering`. Map shows the seeded bunker stations (Singapore, Rotterdam, Fujairah, etc.) with live prices, wait times, and quality scores. Investor takeaway: **"this is operational data, not a brochure."** Navigate to `/sanctions-screening`. Trigger a screen on the seeded vessel. OFAC status badge flips to **HIT**. The A11oy handoff fires automatically because the policy threshold tripped. Show the ownership network graph in the **Sanctions Chain Explorer**. ## 9. Receipt inspector & closing (90s) Open the receipt drawer (top-right). Show the most recent N receipts from the `vessels-formula-thesis` chain — each linked to its predecessor via `prevHash`. Pick one, expand, show: - formula id (e.g. `normalizedRiskScore`) - inputs hash + result hash - sequence number - `selfHash` and `prevHash` Closing line: *"Every number you saw is from a persisted table. Every decision left a receipt. The math is in-page, not in a slide. That's the bar."* --- ## What to NOT click - `/cortex/*` deep tabs — they have great content but they branch the narrative. - Anything tagged `// AMARU_HOOK:` — deferred behind that marker. - The warm-gold redesign surfaces (still landing under #5096). ## If something breaks - If a chart is empty: hit the recompute / detect button on the page — both routes seed shape on first call. - If a receipt hash is missing: the in-memory ReceiptChain resets on server restart. Run any compute endpoint once to re-bootstrap the chain. - If a page 404s: check that `vessels-formula-thesis` is registered in `artifacts/api-server/src/routes/groups/vessels.ts`.
