+# To-do
+
+Open items that aren't tied to a single roadmap phase. Tick them off (or delete them) as they're resolved. Phase work lives in [ROADMAP.md](ROADMAP.md).
+
+## Project setup
+
+- [ ] **Code of Conduct contact.** Replace the placeholder in [CODE_OF_CONDUCT.md](../CODE_OF_CONDUCT.md) with a reporting email address, ideally a project alias rather than a personal one.
+- [ ] **Source code link.** The About page links to `https://www.equineform.com` for now (default in `src/lib/config.ts`, overridable with `VITE_SOURCE_URL`). Change it to the public git repository once one exists, and use the same URL for issue links in CONTRIBUTING.md.
+- [ ] **CI on Gitea.** Confirm Actions is enabled for the repository and a runner is registered, then check the first run of `.gitea/workflows/ci.yml` passes. Keep the Playwright container tag in the workflow in sync with `@playwright/test`.
+
+## Done
+
+- [x] Product name: **Open SafetyLog EHS** (decided 2026-10-06). Note: Insight Works sells a similarly named free "Safety Logbook" EHS app for Microsoft Business Central; run a USPTO trademark search before a public launch.
+- [x] CONTRIBUTING.md and CODE_OF_CONDUCT.md (Contributor Covenant 2.1)
+- [x] About page with source-code link (AGPL-3.0 section 13)
