The document is structured the way most agile product teams organize a feature: high‑level overview, user‑stories, functional & non‑functional requirements, UI/UX design, data model changes, API contract, security, analytics, rollout plan, and test coverage. Feel free to cherry‑pick the sections that match your team’s workflow.

Non‑Functional Requirements

| # | Requirement | Metric / Test | |---|-------------|---------------| | NFR‑001 | Latency – suggestion API ≤ 300 ms (95th percentile) | Load test with 500 concurrent users | | NFR‑002 | Accuracy – ≥ 85 % of suggestions match the “gold‑standard” filter set generated by data‑science team | Offline evaluation on a held‑out dataset | | NFR‑003 | Accessibility – all interactive elements reachable via keyboard, ARIA‑labelled, WCAG 2.1 AA | Axe automated scan + manual testing | | NFR‑004 | Internationalisation – UI strings externalised, support for EN, ES, FR, DE | Regression test on locale switch | | NFR‑005 | Security – no injection via free‑text queries, all inputs sanitized | OWASP ZAP scanning | | NFR‑006 | GDPR – any saved Smart‑Searches stored with user consent flag; deletable on request | Data‑privacy audit | SONE-071
