**What changed** Dynamic parameter rendering now evaluates only the coder parameter blocks and what they reference. Other root-module resources are skipped. Parameter, preset, and tag values are unchanged; optimizing rendering on large templates. **How to revert** Set `CODER_DYNAMIC_PARAMETERS_FULL_EVALUATION=true` (or `--dynamic-parameters-full-evaluation`) on `coder server` to restore full evaluation. The flag is hidden and needs no restart of workspaces. If you need it, please [open an issue](https://github.com/coder/coder/issues/new) with the template so we can fix the root cause. **Troubleshooting** Symptoms would be a parameter default, option list, preset value, or workspace tag that shows as unknown or empty after upgrading, when it was populated before. Confirm by setting the flag above; if the value comes back, report it. Templates written in `.tf.json` are not affected (they always use full evaluation). **Why** Rendering re-ran the entire template graph on every parameter change in the workspace form, which dominated latency on large templates. Resources a workspace would create cannot feed a parameter, so evaluating them is wasted work. The optimization lives in coder/preview#226 (coder/trivy#74); this PR adds the deployment-level escape hatch. --- - `CODER_DYNAMIC_PARAMETERS_FULL_EVALUATION` / `--dynamic-parameters-full-evaluation` (hidden, default `false`) on `DeploymentValues`. - `dynamicparameters.PreviewOptions(dv)` maps it to `preview.OptionFullEvaluation()`; `dynamicparameters.WithPreviewOptions` threads it through the loader to `preview.Preview`. - Wired at the three render paths that hold deployment values: the template version tags extractor, the dynamic parameters websocket, and `wsbuilder` builds created from `coderd` (which call `.DeploymentValues(...)`). Not covered: the autobuild lifecycle executor and the enterprise prebuilds reconciler construct `wsbuilder` without deployment values, so builds started from those paths use preview's default regardless of the flag. Those only re-render for builds, not the keystroke websocket path the optimization targets. Prepared with Coder Agents assistance.
