# Rsync Manager — Direct Distribution Release

Rsync Manager is designed for direct macOS distribution rather than the Mac App Store because it intentionally launches `rsync`/`ssh` and accesses user-selected arbitrary paths.

## Release security baseline

- Developer ID Application signing.
- Hardened Runtime enabled.
- App Sandbox intentionally disabled for this product architecture.
- No Hardened Runtime exception entitlements.
- SSH host-key verification is never disabled.
- SSH uses BatchMode, connection timeout and keepalive limits.
- Password storage/authentication is not supported; use a private key or the macOS SSH agent.
- Advanced rsync arguments that can replace the SSH transport, run remote commands, load passwords, read/write arbitrary option/list/log/batch files or bypass controlled delete handling are rejected.
- Scheduled/file-watch `--delete` requires explicit per-job authorisation.
- Run logs are sanitised and capped before storage and expire according to Settings.
- `PrivacyInfo.xcprivacy` declares no tracking/no collected data and the UserDefaults required-reason API.

## Mandatory preflight

Before every release archive, run on the release Mac:

```bash
./Scripts/release-preflight.sh
```

This performs the static security policy checks, validates the privacy manifest, and performs a clean unsigned **Release** build with the installed macOS SDK so compiler/typecheck warnings or SDK incompatibilities are caught before signing.

## Archive

In Xcode select **Any Mac (Apple Silicon, Intel)**, choose **Product > Archive**, then distribute using **Developer ID**.

Alternatively:

```bash
xcodebuild -project RsyncManager.xcodeproj -scheme RsyncManager -configuration Release -archivePath build/RsyncManager.xcarchive archive
```

Choose your Developer ID Application certificate/team in Xcode signing settings before archiving.

## Verify signature

```bash
codesign --verify --deep --strict --verbose=2 /path/to/RsyncManager.app
codesign -d --entitlements :- /path/to/RsyncManager.app
```

The Release build should show Hardened Runtime and should not contain `com.apple.security.get-task-allow`.

## Notarise

Store notarisation credentials in a Keychain profile once:

```bash
xcrun notarytool store-credentials "RsyncManagerNotary"
```

Submit a signed ZIP/DMG/PKG:

```bash
ditto -c -k --keepParent /path/to/RsyncManager.app RsyncManager.zip
xcrun notarytool submit RsyncManager.zip --keychain-profile "RsyncManagerNotary" --wait
```

Staple and validate:

```bash
xcrun stapler staple /path/to/RsyncManager.app
xcrun stapler validate /path/to/RsyncManager.app
spctl --assess --type execute --verbose=4 /path/to/RsyncManager.app
```

## Pre-release functional security tests

1. Local source nested inside destination is rejected.
2. Local destination nested inside source is rejected.
3. SSH host beginning with `-` is rejected.
4. SSH username containing spaces/control characters is rejected.
5. A `.pub` key cannot be selected as the effective private key.
6. Advanced arguments `-e`, `--rsh`, `--rsync-path`, `--password-file`, `--files-from`, `--log-file`, `--write-batch`, `--remove-source-files`, `--delete*` and `-M` are rejected, and malformed quoting is rejected.
7. Remote destination shell metacharacters are rejected before rsync is launched.
8. Scheduled/watch job using `--delete` cannot run until **Allow unattended delete** is explicitly enabled.
9. SSH to a previously unknown host does not silently bypass host-key checking.
10. Scheduled SSH job with unavailable authentication fails rather than prompting indefinitely.
11. History expiry removes old completed runs according to Settings.
12. A failed persistent SwiftData store opens Recovery Mode instead of immediately crashing.
13. `Scripts/security-check.sh` passes before every signed build.
