Derive the data folder of a plugin from its settings class

A plugin with a settings class already names itself in `plugin_name`;
passing the name again to plugin_data_folder() repeats it and can drift.
Add a `data_folder()` class method on MVTPluginSettings which returns
plugin_data_folder() for the class's validated plugin name (works on the
class and on an instance); plugin_data_folder(name) stays as the function
underneath for plugins without a settings class.

+### VirusTotal package lookups
+
+AndroidQF records APK file hashes in `packages.json`. MVT can optionally look up non-system APK hashes on VirusTotal while checking an AndroidQF acquisition:
+
+```bash
+MVT_VT_API_KEY=<key> mvt-android check-androidqf --virustotal /path/to/androidqf-output

+
+The `--virustotal` option is disabled by default because it sends APK hashes to VirusTotal and requires network access. It uses the `VT_API_KEY` MVT configuration value, which can also be provided through the `MVT_VT_API_KEY` environment variable.
+
+To avoid exhausting free VirusTotal API quotas, MVT waits 16 seconds between package hash requests by default. Use `--delay` to change the delay, or `--delay 0` to disable throttling:
+
+```bash
+mvt-android check-androidqf --virustotal --delay 30 /path/to/androidqf-output

 ## Android Intrusion Logs
 
 On devices where the user has opted into Android's [**Advanced Protection Mode**](https://support.google.com/android/answer/16339980) and turned on the optional Intrusion Logging featrue, Android can create and archive structured *Intrusion Logs* in an encrypted format. These logs record DNS queries, outbound network connections, process starts, ADB activity and other security-relevant events, and are a high-fidelity complement to the rest of an AndroidQF acquisition. The logs are generated on-device and encrypted before being stored in the Google account associated with the device. The encryption key is protected by the user device PIN. The intrusion log data is not accessible to Google.

+# Custom CLI Commands
+
+MVT can load additional top-level commands into `mvt-ios` and `mvt-android`.
+Custom commands are different from [custom forensic modules](index.md#custom-modules):
+commands add new CLI operations, while modules add analysis steps to existing
+`check-*` commands.
+
+!!! warning
+
+    Custom commands run as trusted Python code inside the MVT process. Install
+    or load commands only from sources you trust. MVT does not sandbox
+    third-party commands, and the MVT maintainers do not maintain them.
+
+## Install a Command Package
+
+Python packages can register a Click command or group for either MVT CLI. A
+minimal package can expose this command from `my_mvt_plugin.py`:
+
+```python
+import click
+
+
+@click.command()
+@click.argument("path", type=click.Path(exists=True))
+def summarize(path):
+    """Summarize an acquisition."""
+    click.echo(f"Summarizing {path}")
+```
+
+Register the object in the package's `pyproject.toml`. The entry-point name is
+the command users invoke:
+
+```toml
+[project.entry-points."mvt.ios.cli_plugins"]
+summarize = "my_mvt_plugin:summarize"
+
+[project.entry-points."mvt.android.cli_plugins"]
+summarize = "my_mvt_plugin:summarize"
+```
+
+Use only the iOS or Android group if the command is platform-specific. After
+installing the package in the same environment as MVT, it appears directly in
+the appropriate CLI:
+
+```bash
+mvt-ios summarize ./ios-backup
+mvt-android summarize ./androidqf-output
+```
+
+For a `pipx` installation of MVT, inject the plugin into MVT's environment:
+
+```bash
+pipx inject mvt my-mvt-plugin
+```
+
+When MVT is installed in an active virtual environment, install the plugin with
+`pip` in that environment.
+
+Command packages that need their own settings, such as an API key, should store
+them in a namespaced [plugin configuration file](plugin_configuration.md)
+rather than in MVT's own `config.yaml`.
+
+## Load a Command File
+
+For local commands that are not packaged, create a Python file that exports one
+Click command or group named `cli`:
+
+```python
+import click
+
+
+@click.command("case-summary")
+@click.argument("path", type=click.Path(exists=True))
+def cli(path):
+    """Summarize a case directory."""
+    click.echo(f"Summarizing {path}")
+```
+
+Pass the file before the custom command name:
+
+```bash
+mvt-ios --load-command ./case_summary.py case-summary ./ios-backup
+```
+
+`--load-command` can be repeated and also accepts a folder. MVT loads
+non-hidden top-level `*.py` files in sorted order and skips `__init__.py`.
+Every loaded file must export one `cli` object.
+
+To load a file or folder on every invocation, set the platform-specific
+environment variable:
+
+```bash
+export MVT_IOS_CUSTOM_COMMANDS=./ios_commands
+export MVT_ANDROID_CUSTOM_COMMANDS=./android_commands
+```
+
+## Naming and Errors
+
+Built-in MVT commands cannot be replaced. External command names must also be
+unique; when installed packages or environment paths collide, MVT keeps the
+first command and logs a warning. A collision from an explicit
+`--load-command` is a usage error.
+
+A package entry point or environment command that cannot be imported appears
+as a marked broken command without preventing other MVT commands from working.
+Invoke that command to see its package or file source and the underlying error.
+An invalid command supplied explicitly with `--load-command` fails immediately
+with a usage error.
+
+Installed command packages use the entry-point name as the CLI command name.
+The entry point must resolve to a `click.Command` or `click.Group`.

+
+## Local environment
+
+MVT uses `uv` for dependency management. To install the project and development dependencies from the locked environment, run:
+
+```bash
+make install
+```
+
+## Testing
+
+MVT uses `pytest` for unit and integration tests. Code style consistency is maintained with `ruff` and `mypy`. All can
+be run automatically with:
+
+```bash
+make check
+```
+
+Run these tests before making new commits or opening pull requests.
+
+## Module dependencies
+
+Modules can require other modules to run first by declaring their classes in
+`dependencies`. The command runner uses a stable topological ordering, so the
+existing module list order is preserved wherever dependency constraints allow.
+
+```python
+class DependentModule(MVTModule):
+    dependencies = (PrerequisiteModule,)
+
+    def run(self):
+        prerequisite_results = self.get_dependency_results(PrerequisiteModule)
+```
+
+Selecting a single module also runs its transitive dependencies. If a dependency
+is unavailable or the dependency graph contains a cycle, the command logs a
+warning and does not run any modules.
+
+## Custom modules
+
+Module-running `check-*` commands can load custom modules from Python files that
+are not installed as part of MVT. Load one file with:
+
+```bash
+mvt-ios check-backup --load-module ./example_module.py --output ./out ./backup
+```
+
+You can also load a folder. MVT loads non-hidden top-level `*.py` files in
+sorted order and skips `__init__.py`:
+
+```bash
+mvt-ios check-fs --load-module ./custom_modules ./filesystem-dump
+```
+
+Set `MVT_CUSTOM_MODULES` to load a folder for every module-running command. This
+folder is loaded before any `--load-module` path:
+
+```bash
+MVT_CUSTOM_MODULES=./custom_modules mvt-android check-bugreport ./bugreport.zip
+```
+
+Custom modules are normal `MVTModule` subclasses:
+
+```python
+from mvt.common.module import MVTModule
+
+
+class ExampleCustomModule(MVTModule):
+    supported_commands = (("ios", "check-backup"), ("ios", "check-fs"))
+    slug = "example_custom_module"
+
+    def run(self):
+        self.results = [{"message": "custom module ran"}]
+
+    def check_indicators(self):
+        pass
+
+    def serialize(self, result):
+        return None
+```
+
+Use `supported_commands` to declare the platform/command pairs a module
+supports. Empty `supported_commands` means the module will not run and MVT logs
+a warning. This explicit declaration is required for every command. Supported
+pairs are:
+
+```python
+("ios", "check-backup")
+("ios", "check-fs")
+("ios", "check-iocs")
+("ios", "check-sysdiagnose")
+("android", "check-backup")
+("android", "check-bugreport")
+("android", "check-androidqf")
+("android", "check-intrusion-logs")
+("android", "check-iocs")

+
+Custom modules can depend on existing MVT module classes. Dependencies are
+resolved with the same ordering logic as built-in modules, and custom modules
+are appended after built-ins before ordering:
+
+```python
+from mvt.common.module import MVTModule
+from mvt.ios.modules.backup.manifest import Manifest
+
+
+class DependentCustomModule(MVTModule):
+    supported_commands = (("ios", "check-backup"),)
+    dependencies = (Manifest,)
+
+    def run(self):
+        manifest_results = self.get_dependency_results(Manifest)
+        self.results = [{"manifest_entries": len(manifest_results)}]
+```
+
+## Installed module packages
+
+Python packages can register modules so they load automatically in every
+module-running `check-*` command, without `--load-module` or
+`MVT_CUSTOM_MODULES`. Register an entry point in the `mvt.modules` group in
+the package's `pyproject.toml`:
+
+```toml
+[project.entry-points."mvt.modules"]
+mvt-plugin-amnesty-custom = "mvt_plugin_amnesty_custom:get_modules"
+```
+
+The entry point must resolve to an iterable of `MVTModule` subclasses, or to
+a callable returning one:
+
+```python
+from mvt.common.module import MVTModule
+
+
+class PackagedModule(MVTModule):
+    supported_commands = (("ios", "check-backup"),)
+
+    def run(self):
+        self.results = [{"message": "packaged module ran"}]
+
+
+def get_modules() -> list[type[MVTModule]]:
+    return [PackagedModule]
+```
+
+Installed modules follow the same rules as other custom modules: each module
+must declare `supported_commands`, and dependencies are resolved with the
+standard ordering logic. A broken entry point is skipped with a warning and
+does not prevent MVT from running. As with custom commands, installed module
+packages run as trusted code inside the MVT process, so install only packages
+from sources you trust.
+
+For a `pipx` installation of MVT, inject the package into MVT's environment:
+
+```bash
+pipx inject mvt mvt-plugin-amnesty-custom
+```
+
+Module packages that need their own settings, such as an API key, should store
+them in a namespaced [plugin configuration file](plugin_configuration.md)
+rather than in MVT's own `config.yaml`.
+
+### Naming module packages
+
+Name module packages `mvt-plugin-<name>` (import package `mvt_plugin_<name>`),
+and include the name of the publishing organization or author so packages from
+different groups do not collide: for example, Amnesty International's custom
+modules would be distributed as `mvt-plugin-amnesty-custom` with the import
+package `mvt_plugin_amnesty_custom`.
+
+The prefix makes module packages easy to find on PyPI and keeps their import
+names from clashing with unrelated Python packages. It is a convention, not a
+technical requirement: modules load through the `mvt.modules` entry point
+regardless of what the package is called, and existing packages with other
+names keep working. Note that the prefix is also not a mark of authenticity —
+anyone can publish a package with any available name, so vet a module package
+and its publisher before installing it, whatever it is called.
+
+### Module logging
+
+Modules log through `self.log`, and MVT names the logger for where the module
+came from. MVT's own modules log under their dotted path (for example
+`mvt.ios.modules.mixed.whatsapp`). Everything external is namespaced under
+`mvt.ext` to keep it visually distinct from built-in modules and isolated from
+MVT's internal logger tree:
+
+- Installed packages log under `mvt.ext.<package>`, with the `mvt_plugin_`
+  prefix stripped: modules in `mvt_plugin_amnesty_custom` log as
+  `mvt.ext.amnesty_custom.*`.
+- Files loaded with `--load-module` or `MVT_CUSTOM_MODULES` log as
+  `mvt.ext.<file name>`.
+
+## Auditing loaded modules
+
+Because installed module packages load automatically, MVT records where every
+module came from:
+
+- `--list-modules` groups the available modules by source: MVT itself
+  (with its version), each installed package (with its version and, when
+  installed directly from a repository, the commit), and each file loaded
+  with `--load-module` or `MVT_CUSTOM_MODULES` (with the SHA-256 hash of the
+  file).
+- When a command runs with an `--output` folder, the `command.log` file
+  records one line per module source with the source's version or hash and
+  the list of modules loaded from it.
+
+## Profiling
+
+Some MVT modules extract and process significant amounts of data during the analysis process or while checking results against known indicators. Care must be
+take to avoid inefficient code paths as we add new modules.
+
+MVT modules can be profiled with Python built-in `cProfile` by setting the `MVT_PROFILE` environment variable.
+
+```bash
+MVT_PROFILE=1 dev/mvt-ios check-backup test_backup
+```

+# Plugin Configuration
+
+Plugin packages that add [custom CLI commands](custom_commands.md) or
+[modules](index.md#installed-module-packages) often need to store their
+own settings, such as an API key, a server URL or the timestamp of the last
+synchronization. MVT provides a namespaced settings base class so each plugin
+keeps its configuration in its own file, and a data folder for anything else a
+plugin needs to keep on disk.
+
+!!! warning
+
+    Do not write plugin settings to MVT's own `config.yaml`. MVT rewrites that
+    file with the settings it knows about every time it starts, so any other
+    section is deleted.
+
+## Where Settings Are Stored
+
+Each plugin gets one YAML file in a `plugins` folder next to MVT's own
+configuration:
+
+```
+~/.config/mvt/plugins/<plugin name>.yaml
+```
+
+The exact parent folder follows the platform convention used for MVT's
+`config.yaml` (for example `~/Library/Application Support/mvt` on macOS). Use
+`mvt.common.plugin_config.plugin_config_path()` instead of building the path by
+hand.
+
+Plugin names must be lowercase and may only contain letters, digits and dashes,
+matching the `mvt-plugin-<name>` package naming convention. MVT creates the
+`plugins` folder with `0700` permissions and writes the settings files with
+`0600` permissions, because they commonly hold credentials. Files are written
+through a temporary file and moved into place, so an interrupted save never
+leaves a partially written settings file behind.
+
+## Plugin Data Folder
+
+Everything else a plugin keeps on disk, such as a cache, a downloaded artifact
+or synchronization state, belongs in the folder returned by the `data_folder()`
+class method of the plugin's settings class, or by
+`mvt.common.plugin_config.plugin_data_folder()` called with the plugin name if
+the plugin has no settings class:
+
+```
+~/.local/share/mvt/plugin-data/<plugin name>/                # Linux
+~/Library/Application Support/mvt/plugin-data/<plugin name>/ # macOS
+```
+
+The folder sits beside MVT's own data, such as the downloaded indicators. It is
+created if it is missing, with `0700` permissions. Asking for it again returns
+the same path and leaves the contents alone, so a plugin can ask for it every
+time it needs the folder. `ExamplePluginSettings` below is the settings class
+defined in the next section:
+
+```python
+import os
+
+
+def cache_path() -> str:
+    folder = ExamplePluginSettings.data_folder()
+    return os.path.join(folder, "virustotal_lookups_cache.json")
+```
+
+A plugin which has no settings class calls
+`plugin_data_folder("example-plugin")` instead.
+
+Do not fall back on a path of your own such as `~/.cache/example-plugin`: it
+is a Linux-only convention, and MVT will not create it for you.
+
+## Defining Plugin Settings
+
+Subclass `MVTPluginSettings`, set `plugin_name` and declare typed fields with
+defaults:
+
+```python
+from typing import Optional
+
+from mvt.common.plugin_config import MVTPluginSettings
+
+
+class ExamplePluginSettings(MVTPluginSettings):
+    plugin_name = "example-plugin"
+
+    API_KEY: Optional[str] = None
+    MAX_RESULTS: int = 25
+    LAST_SYNC: Optional[str] = None
+```
+
+`load()` returns the current settings and `save()` writes them back:
+
+```python
+from datetime import datetime, timezone
+
+import click
+
+
+def sync():
+    settings = ExamplePluginSettings.load()
+    if not settings.API_KEY:
+        raise click.ClickException(
+            "No API key configured. Set MVT_PLUGIN_EXAMPLE_PLUGIN_API_KEY or "
+            "run 'example-plugin configure'."
+        )
+
+    settings.LAST_SYNC = datetime.now(timezone.utc).isoformat()
+    settings.save()
+```
+
+A missing settings file is not an error: the plugin then runs on the field
+defaults and on whatever the environment provides. `save()` only persists the
+values that differ from the defaults, and it never touches MVT's `config.yaml`.
+A settings file that cannot be parsed, or that does not hold a mapping of
+setting names to values, raises a `PluginConfigLoadError` naming the file.
+
+Every subclass that sets its own `plugin_name` gets its own file and its own
+environment namespace. A subclass that does not redefine `plugin_name` inherits
+it, and therefore shares the file and the environment variables of its parent
+class.
+
+## Environment Variables
+
+Every field can also be set with an environment variable. The prefix is
+`MVT_PLUGIN_`, followed by the plugin name upper-cased with dashes replaced by
+underscores, followed by the field name. For the example above:
+
+```bash
+export MVT_PLUGIN_EXAMPLE_PLUGIN_API_KEY=...
+export MVT_PLUGIN_EXAMPLE_PLUGIN_MAX_RESULTS=50
+```
+
+Settings resolve in this order, from highest to lowest priority:
+
+1. Arguments passed to the settings class directly, such as
+   `ExamplePluginSettings(API_KEY="...")`
+2. Environment variables
+3. The plugin's YAML file
+4. The field defaults declared on the settings class
+
+!!! tip
+
+    On shared or multi-user machines, prefer passing API keys through
+    environment variables rather than saving them to the plugin file. `save()`
+    skips every value that the environment currently supplies, so a credential
+    provided that way is not copied into the settings file when a plugin saves
+    an unrelated setting.
+
+Unknown keys in a plugin's YAML file are ignored, so a settings file written by
+a newer version of a plugin does not break an older one.

+# Check an iOS Sysdiagnose
+
+`mvt-ios check-sysdiagnose` prepares an iOS sysdiagnose archive for analysis by
+custom MVT modules. MVT does not include built-in sysdiagnose modules. You must
+load at least one custom module that explicitly supports this command.
+
+The command accepts either an extracted sysdiagnose directory or the original
+gzip-compressed tar archive.
+
+```bash
+mvt-ios check-sysdiagnose \
+    --load-module ./sysdiagnose_modules.py \
+    --output ./results \
+    ./sysdiagnose_2024.01.02_03-04-05+0200.tar.gz
+```
+
+Use `--hashes` to include hashes for analyzed files in `info.json`, and
+`--list-modules` to display the eligible custom modules without running them.
+
+## Writing a custom module
+
+Extend `SysdiagnoseExtraction` to access the archive contents consistently for
+both directory and tar inputs. Each module must declare the command explicitly
+in `supported_commands`.
+
+```python
+from mvt.ios.modules.sysdiagnose import SysdiagnoseExtraction
+
+
+class ExampleSysdiagnoseModule(SysdiagnoseExtraction):
+    supported_commands = (("ios", "check-sysdiagnose"),)
+    slug = "example_sysdiagnose"
+
+    def run(self):
+        paths = self._get_files_by_pattern("*/example.log")
+        if paths:
+            content = self._get_file_content(paths[0]).decode("utf-8", "replace")
+            self.results = [{"content": content}]
+
+    def check_indicators(self):
+        pass
+
+    def serialize(self, result):
+        return None
+```
+
+The base class provides `from_sysdiagnose_folder()` and
+`from_sysdiagnose_tar()` setup hooks, as well as protected file lookup, file
+reading, and timezone extraction helpers. IPS crash-report metadata is exposed
+on `ips_files`.
