 - Aligns engineering efforts with business goals
 - Provides a north star for feature development
 - Establishes acceptance criteria before implementation begins
-- Creates a contract between product and engineering
+- Creates a contract between product, engineering, security, and operations.
 
 **Content Guidelines**:
 - User stories with clear acceptance criteria (As a X, I want Y so that Z)
-- Product Requirements Documents (PRDs) with success metrics
+- Product Requirements Documents with clear success metrics and KPIs.
-- Non-functional requirements (performance, security, scalability)
+- Nonfunctional requirements covering performance, scalability, availability, reliability, and privacy.
-- Boundary definitions (what's in scope vs. out of scope)
+- Boundary definitions that state what is in scope and out of scope.
-- Do not cite any other documents as requirements.md is the first document to be created in the ASG Framework
+- Security requirements including threat model outcomes, authentication and authorization expectations, data classification, encryption requirements, and compliance controls.
+- Observability requirements specifying required telemetry, metrics, traces, logs, alerting thresholds, and retention policies.
+- Traceability rule: do not cite other documents as the source of requirements. requirements.md is the canonical first document in the ASG Framework.
 
 **Best Practices**:
 - Link each requirement to a measurable KPI

-[What problem are we solving?]
+- Business Goal
+- User Stories (with acceptance criteria)
+- KPIs & Targets (e.g., "99.95% availability", "<200ms p95 latency")

+### 3.1 Performance & Scalability
-  - Acceptance Criteria: [details]
+- [e.g., Support 10K TPS, scale horizontally to 100 nodes]
 
-## Non-Functional Requirements
+### 3.2 Availability & Reliability
-- Performance: [details]
+- [e.g., SLO: 99.9% monthly uptime, MTTR < 10min]
-- Security: [details]
-- Scalability: [details]
 
-## Out of Scope
+### 3.3 Privacy & Security
-- [What's explicitly excluded]
+- Data Classification: [e.g., PII, PHI]
+- Threat Model Outcomes: [e.g., "Mitigates replay attacks via nonce + timestamp"]
+- Auth/Z Expectations: [e.g., RBAC with 3 roles: viewer, editor, admin]
+- Encryption: [e.g., TLS 1.3+, AES-256 at rest]
+- Compliance: [e.g., GDPR Art. 32, SOC2 Type II]
+
+### 3.4 Observability & Telemetry
+- Required Logs: [e.g., `user_id`, `request_id`, `status`, `latency_ms`]
+- Critical Metrics: [e.g., `auth_failures_total`, `api_latency_seconds{quantile=0.99}`]
+- Tracing: [e.g., Zipkin/B3 propagation, 10% sampling]
+- Alerting: [e.g., `auth_failure_rate > 5%/min` triggers PagerDuty]
+- Retention: [e.g., Logs: 30 days, Metrics: 1 year]
