+#### Audit Mode
+
+The [`--permission-audit`][] flag enables audit mode for the Permission Model.
+In audit mode, permission checks are performed but access is **not** denied —
+no `ERR_ACCESS_DENIED` error is thrown. Instead, each permission violation is
+published through the `node:diagnostics_channel` module, allowing the
+application to observe and log which operations would be denied under enforce
+mode. Execution continues normally.
+
+Audit mode is useful for discovering what permissions your application
+requires before deploying with [`--permission`][]. It can also be combined
+with the [`--allow-fs-read`][], [`--allow-fs-write`][],
+[`--allow-child-process`][], [`--allow-worker`][], [`--allow-addons`][], and
+[`--allow-wasi`][] flags to audit a subset of permissions while granting
+others.
+
+When a permission check fails in audit mode, a message is published to the
+diagnostics channel corresponding to the denied scope. The channel names are:
+
+* `node:permission-model:fs` — File System (read and write)
+* `node:permission-model:child` — Child Process
+* `node:permission-model:worker` — Worker Threads
+* `node:permission-model:inspector` — Inspector
+* `node:permission-model:wasi` — WASI
+* `node:permission-model:addon` — Native Addons
+
+Each message is an object with the following properties:
+
+* `permission` {string} The name of the denied permission scope.
+* `resource` {string} The resource that access was denied to (e.g. a file path).
+
+```js
+const diagnostics_channel = require('node:diagnostics_channel');
+
+diagnostics_channel.channel('node:permission-model:fs').subscribe((msg) => {
+  console.log(`Permission denied: ${msg.permission} on ${msg.resource}`);
+});
+
+// Running with --permission-audit, this publishes a diagnostics channel
+// message but does not throw
+const fs = require('node:fs');
+fs.readFileSync('/etc/passwd');
+```
+
+If both [`--permission`][] and [`--permission-audit`][] are specified,
+`--permission` takes precedence and the Permission Model runs in enforce mode.
