+# Daily Task Log: InnerHTML Migration Agent
+
+- **Date:** 2026-02-16
+- **Agent:** innerhtml-migration-agent
+- **Status:** Completed
+
+## Summary
+Refactored `js/docsView.js` to replace `innerHTML` usage with safe DOM manipulation methods.
+
+## Actions Taken
+1. Analyzed `js/docsView.js` and identified 8 instances of `innerHTML`.
+2. Refactored 7 instances to use `document.createElementNS`, `replaceChildren`, and `setAttribute`.
+3. Retained 1 instance for `marked.parse()` as it renders trusted Markdown content; added documentation.
+4. Updated `scripts/check-innerhtml.mjs` baseline.
+5. Verified changes with `npm run lint` and `npm run test:unit`.
+6. Verified frontend functionality with Playwright and visual inspection.
+
+## Artifacts
+- Code changes in `js/docsView.js`
+- Updated baseline in `scripts/check-innerhtml.mjs`
+- Log files moved to `artifacts/innerhtml-migration/2026-02-16/`
