AI SDLC Standards: cross-cutting requirements mono repo

- Security: input validation, SQL injection, auth annotations, secrets, CVE checks
- Architecture: API contract first, service boundaries, breaking change protocol
- DevOps: health checks, structured logging, resource limits, rollback safety
- Cost: resource tagging, auto-scaling limits, storage lifecycle
- Deterministic compliance checker (.tests/check.sh)
- Agent skill for context injection (Cursor, OpenSpec, Claude Code examples)
- Demo with intentional violations

+# Security Requirements
+
+Phase: implementation
+Enforcement: informational (graduating to blocking Q3 2026)
+
+## SEC-001: Input Validation
+
+All external input (API request bodies, query parameters, headers, file uploads) MUST be validated through a schema validator before processing.
+
+**Rule:** No raw request body access in business logic. All endpoints must define and validate against a schema (JSON Schema, protobuf, or framework-equivalent).
+
+**Test:** Grep for direct `request.body` / `req.body` / `getParameter()` usage outside of controller/validation layer.
+
+```
+# Bad
+String name = request.getParameter("name");
+db.query("SELECT * FROM users WHERE name = '" + name + "'");
+
+# Good
+ValidatedInput input = validator.validate(request, CreateUserSchema.class);
+userService.create(input);
+```
+
+## SEC-002: No Raw SQL
+
+All database queries MUST use parameterized queries or an ORM. No string concatenation in SQL statements.
+
+**Rule:** Zero tolerance for SQL string concatenation with user-controlled values.
+
+**Test:** Regex scan for SQL keywords adjacent to string concatenation operators (`+`, `concat`, `format`, `f"`, template literals).
+
+## SEC-003: Authentication Annotations
+
+All new REST endpoints MUST have an explicit auth annotation. No endpoint may be implicitly public.
+
+**Rule:** Every `@RequestMapping`, `@GetMapping`, `@PostMapping` (or equivalent) must be accompanied by `@ReltioSecured` or `@PublicEndpoint`. Missing annotation = violation.
+
+**Test:** AST/regex check that every endpoint method has an auth annotation.
+
+## SEC-004: Secrets in Code
+
+No hardcoded secrets, tokens, passwords, or API keys in source code.
+
+**Rule:** All secrets must come from environment variables, vault, or config service. String literals matching secret patterns are violations.
+
+**Test:** Regex scan for patterns: API keys, JWT tokens, passwords in string literals, base64-encoded credentials.
+
+## SEC-005: Dependency Vulnerability
+
+No new dependencies with known critical/high CVEs.
+
+**Rule:** Any new dependency added to `pom.xml`, `package.json`, `go.mod`, or equivalent must pass a vulnerability scan.
+
+**Test:** Run `npm audit` / `mvn dependency-check:check` / `govulncheck` on changed dependency files.
