   - `dcq-reports/` is created at the project root when running `checks`
     or the `*-fix` commands (logs + patch previews).
   - Add `dcq-reports/` to `.gitignore` if you do not want to track it.
+- Host-path parity alias:
+  - The add-on installs `.ddev/web-entrypoint.d/90-dcq-host-path-alias.sh`.
+  - On container start, it creates a host-style project-path symlink to
+    `/var/www/html` so absolute host paths can resolve inside the container.
+  - After first install/upgrade that adds this hook, run `ddev restart` once
+    so the alias is established in the running container.
+  - On macOS paths under `/private/...`, it also creates a `/...` companion
+    alias (for example `/tmp/...`) to cover common host-path forms.
+  - The alias is enforced at startup; if startup cannot safely establish the
+    alias, startup emits an error and wrappers should be considered unavailable
+    until the conflict is resolved.
 - ESLint toolchain selection:
   - `ESLINT_TOOLCHAIN=auto` (default) prefers root toolchain when root configs exist.
   - `ESLINT_TOOLCHAIN=core` forces Drupal core JS toolchain.
   - `ESLINT_TOOLCHAIN=root` forces project root toolchain.
 - ESLint config mode:
   - `ESLINT_CONFIG_MODE=nearest` (default) groups by nearest config file.
-  - `ESLINT_CONFIG_MODE=fixed` forces `.eslintrc.passing.json`.
+  - `ESLINT_CONFIG_MODE=fixed` prefers `.eslintrc.passing.json`, then
+    `.eslintrc.json` in the project root.
 - ESLint warning visibility (GitLab CI parity):
   - `DCQ_ESLINT_QUIET=1` (default) adds `--quiet` to `ddev eslint` and
     `ddev eslint-fix`, so warnings are suppressed.

     time. Avoid using it to hide new regressions.
-- PHPStan config fallback:
-  - If no project `phpstan.neon*` exists, the wrapper uses the GitLab template
-    config shipped with the add-on.
+- PHPStan config requirement:

+    `--configuration <path>`.
 - PHPStan level:
   - GitLab CI template defaults use level 0. The installer can set a local default level (0-10).
