 WinGet's `APPINSTALLER_CLI_ERROR_UPDATE_NOT_APPLICABLE` result is treated as
 success because it means the installed ChatGPT version is already current.
 
+### Parsec
+
+Parsec is installed by `applications/parsec/apply.ps1` instead of the WinGet
+DSC document. Parsec publishes mutable installer content at a stable URL, which
+can temporarily leave the WinGet manifest with a stale SHA256 and make the
+entire DSC run fail. The application-local declaration pins the verified file
+version, SHA256, and Authenticode signer thumbprint. The script downloads only
+when Parsec is absent, verifies all three values, then requests elevation and
+runs the official installer for all users. It never bypasses WinGet hash
+verification.
+
 7-Zip is intentionally installed with its normal Windows installer through
 WinGet rather than as a portable Scoop package, because the normal installer
 provides Explorer shell integration.

+The protected Windows Search key doesn't grant write access to administrators,
+so `apply.ps1` applies the desired value from the declarative
+`enhanced-search.json` as `SYSTEM` to set Find my files to Enhanced. It uses a
+uniquely named one-shot Scheduled Task and always unregisters it immediately
+afterward. It doesn't change the key's owner or access-control list and doesn't
+leave a persistent task behind.
+
+Windows Pro still sends required diagnostic data even when `AllowTelemetry` is
+set to the Security value (`0`); only editions that support the Security level
+honor diagnostic data completely off. The configuration nevertheless disables
+optional diagnostic data and every related user-facing toggle. Enhanced search
+indexes the full user profile, so its initial indexing can temporarily use more
+CPU, battery, and storage.
