+- GitHub Actions CI workflow (compile, format, test)
+- Security notice in README documenting the trust boundary
+
+### Changed
+
+- API key log output now shows only last 4 characters instead of first 12
+- `.envrc` untracked and added to `.gitignore` (local direnv preference)
+- Added `@moduledoc` to `RLMWeb.Endpoint`, `RLMWeb.Router`, `RLMWeb.RunListLive`,
+  `RLMWeb.RunDetailLive`, and `RLMWeb.Telemetry`
+- Pre-commit hook skips gracefully when `mix` is not available
+
+### Removed
+
+- `demo_run.exs` — referenced missing `priv/foodlab.epub`; would crash on clone
+- `RLMWeb.PageController`, `RLMWeb.PageHTML` — unused Phoenix generator leftovers
+- `RLMWeb.channel/0` helper — no channels in the application
+- Swoosh dependency and `RLMWeb.Mailer` — no email functionality exists
+- `/dev/mailbox` route — removed with Swoosh

+## Security

+RLM executes LLM-generated Elixir code via `Code.eval_string` with full access to the
+host filesystem, network, and shell. **Do not expose RLM to untrusted users or untrusted
+LLM providers.** It is designed for local development, trusted API backends (Anthropic),
+and controlled environments. There is no sandboxing beyond process-level isolation and
+configurable timeouts.
