- Update AGENTS.md and .agents/rules/blog-system.md with strict TDD mandate - Extract Eleventy custom filters into modular src/_filters/index.js for unit testing - Add npm test script using Node.js native test runner (node:test) - Create test/site-config.test.js for environment validation and fatal error assertions - Create test/filters.test.js for adversarial filter edge cases (dates, limits, reading time, headings) - Create test/frontmatter-schema.test.js enforcing post metadata contracts - Create test/design-rules.test.js enforcing strict anti-patterns (no glassmorphism, no shadows, max 4px radius) - Create test/build-integrity.test.js checking static output, zero 404 links, and TOC anchor targets
