+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project overview
+
+`id-configurator` is a proprietary CLI tool by InterDiode to "configure a device in an air-gapped environment".
+It targets Python 3.13+ and is packaged with the `uv_build` backend.
+It takes a configuration (JSON or YAML, either from a file or from a base64-encoded environment variable) and applies it to the system, including installing root certificates, configuring package managers, and other system-level settings.
+Modified files are written to a destination directory given with --dst by the user, this directory can be used to build a Docker image.
+The original file system can be provided with --src by the user to detect existing configuration.
+
+Example:
+- the configuration specifies a root certificate to install, the tool will copy it to `<dst>/etc/ssl/certs` and update the system's CA certificates.
+- the configuration specifies a apt source to add and `<src>` contains an existing `/etc/apt/sources.list`, the tool will merge the new source into the existing sources and write the result to `<dst>/etc/apt/sources.list`.
+
+The configuration is expected to be a JSON or YAML object with the following structure:
+
+```yaml
+uuid: <UUID>
+organisation: <string>
+description: <string>
+configurations:
+    certificates:
+      - name: <string>
+        content: <PEM>
+    apt:
+        sources:
+            - name: <string>
+              content: <string>
+        keys:
+            - name: <string>
+              content: <GPG key>
+    yum:
+        repositories:
+            - name: <string>
+              index-url: <string>
+              gpg-url: <string>
+    python:
+        repositories:
+            - name: <string>
+              index-url: <string>
+```
+
+The tool must have an extensible modular structure. Each module can use any part of the configuration, detect if is relevant by checking the current filesystem from `<src>`, and write modified files to `<dst>`.
+Several modules can read the certificates from the configuration and use them differently.
+The tool must be able to run in a Docker container, and must not require any network access.
+It is forbidden to write any file outside of `<dst>`.
+
+The tool must be called by `python -m id_configurator`, or via the console script entry point `id-configurator`.
+
+Here is a preliminary list of modules that will be implemented:
+- install root certificates in the system's CA store
+- configure system package managers:
+  - apt
+  - yum
+  - apk
+  - dnf
+- configure programming language package managers:
+  - python (pip)
+  - ruby (gem)
+  - nodejs (npm)
+  - golang (go)
+  - java (maven, gradle)
+  - php (composer)
+  -
+
+## Current state
+
+This repository is a skeleton: `id_configurator/__init__.py` is currently empty, and `README.md` is empty. `pyproject.toml` already declares a console-script entry point:
+
+```
+id-configurator = "id_configurator:main"
+```
+
+There is no `main` callable yet — implementing it in `id_configurator/__init__.py` (or importing it there) is the first thing needed to make the CLI runnable. No tests, no `[tool.ruff]`/`[tool.pytest]` config, and no CI config exist yet.
+
+## Commands
+
+- Install/sync dependencies: `uv sync`
+- Run the CLI (once `main` exists): `uv run id-configurator`
+- Lint and auto-fix: `uv run ruff check --fix .`
+- Format: `uv run ruff format .`
+- Run all pre-commit hooks (ruff, bandit, shellcheck, commitizen, check-yaml/toml/json, etc.): `uv run pre-commit run --all-files`
+
+There is no test suite yet.
+
+## Conventions
+
+- Python version is pinned to 3.13 (`.python-version`, `requires-python = ">=3.13"` in `pyproject.toml`).
+- `.editorconfig`: 4-space indentation, single quotes, LF line endings, 120 max line length for `.py` files.
+- Commit messages are linted by commitizen via pre-commit, implying Conventional Commits format.
+- The package is proprietary (`Private :: Do Not Upload` classifier) and is not published to PyPI.

+# id-configurator
+
+`id-configurator` is a CLI tool by [InterDiode](https://interdiode.fr/) that configures a device (typically a
+Docker image) in an **air-gapped environment**: no network access is required or ever used.
+
+It reads a single configuration (JSON or YAML), and applies it to a filesystem tree, writing only the files
+that need to change: root certificates, package manager sources (APT, YUM/DNF, APK), and language-specific
+package manager settings (pip/uv/poetry, Maven/Gradle/Ivy/SBT/Leiningen, ...). The result can then be used
+to build a Docker image or otherwise deployed to the target device.
+
+## How it works
+
+- `--dst` points to the destination directory that receives every modified or created file. `id-configurator`
+  never writes anywhere else.
+- `--src` (optional) points to an existing filesystem, used to detect the current configuration (existing
+  APT sources, existing Java keystores, etc.) so it can be extended or disabled instead of blindly overwritten.
+- The configuration is loaded either from a file (`--config`) or from a base64-encoded string, typically an
+  environment variable (`--config-env` / `$ID_CONFIGURATOR_CONFIG`).
+- Each feature is implemented as an independent, self-registering **module**. On `apply`, every module
+  inspects the configuration and the source filesystem and decides for itself whether it has something to
+  do; only relevant modules touch the destination directory.
+
+## Installation
+
+Requires Python 3.13+.
+
+```bash
+uv sync
+```
+
+## Usage
+
+```bash
+# Apply a configuration file to a destination directory
+uv run id-configurator apply --config config.yaml --dst ./output
+
+# Take an existing filesystem into account (e.g. to extend its APT sources)
+uv run id-configurator apply --config config.yaml --src /path/to/rootfs --dst ./output
+
+# Use a base64-encoded configuration from the environment instead of a file
+export ID_CONFIGURATOR_CONFIG=$(base64 -w0 config.yaml)
+uv run id-configurator apply --dst ./output
+
+# Validate a configuration without applying it
+uv run id-configurator validate --config config.yaml
+
+# List the available modules
+uv run id-configurator list-modules
+```
+
+The tool can also be invoked as `python -m id_configurator`.
+
+## Configuration format
+
+The configuration is a JSON or YAML object:
+
+```yaml
+uuid: <UUID>
+organisation: <string>
+description: <string>
+configurations:
+  certificates:
+    - name: <string>
+      content: <PEM>
+  apt:
+    sources:
+      - name: <string>
+        uris: [<string>]
+        suites: [<string>]
+        components: [<string>]
+    keys:
+      - name: <string>
+        content: <GPG key>
+  apk:
+    repositories:
+      - url: <string>
+        key: <RSA public key>
+  yum:
+    repositories:
+      - name: <string>
+        index-url: <string>
+        gpg-url: <string>
+    keys:
+      - name: <string>
+        content: <GPG key>
+  python:
+    repositories:
+      - name: <string>
+        index-url: <string>
+  java:
+    repositories:
+      - name: <string>
+        url: <string>
+```
+
+## Modules
+
+| Module         | Applies to                                                                                            |
+|----------------|--------------------------------------------------------------------------------------------------------|
+| `certificates` | Installs root certificates into the system's CA store (`update-ca-certificates`).                     |
+| `apt`          | Disables existing APT sources and adds the configured ones, in DEB822 format.                         |
+| `apk`          | Disables existing Alpine `/etc/apk/repositories` entries and adds the configured ones, plus their keys.|
+| `yum`          | Disables existing YUM/DNF `.repo` files, adds the configured ones, and imports their GPG keys.         |
+| `python`       | Points pip, uv, poetry and `easy_install` to the configured Python package indexes.                   |
+| `java`         | Adds root certificates to every detected JKS/PKCS12 keystore, and configures Maven, Gradle, Ivy, SBT and Leiningen repositories. |
+
+More modules (npm, nuget, ruby/gem, rust/crates, go, packagist/composer, ...) are planned; see `CLAUDE.md` for the full roadmap.
+

+"""Install root certificates into the system's CA store.
+
+Certificates from the configuration are dropped into the "local" CA
+directory, then the trust store under `/etc/ssl/certs` (bundle + named
+symlinks) is rebuilt in pure Python, mirroring what Debian's
+`update-ca-certificates` shell script does: every certificate enabled in
+`ca-certificates.conf` (read from `<src>`), plus everything found under the
+local certificates directory, is concatenated into a single bundle file and
+gets a `<name>.pem` symlink pointing at it.
+
+The OpenSSL subject-hash symlinks (`<hash>.0`) that `update-ca-certificates`
+also creates, for CApath-style directory lookups, are intentionally not
+reproduced here: none of this tool's own consumers (pip, apt, dnf, apk, the
+JVM, ...) do CApath lookups, they all read the single bundle file.
+
+If `/etc/ssl/certs` is itself a symlink in `<src>` (as on RHEL, where it
+points to `/etc/pki/tls/certs`), the bundle and symlinks are written to
+whatever directory it resolves to instead. The write lands where the
+deployed system will actually look, without ever writing a plain directory
+where that system expects a symlink. In that case `/usr/lib/ssl/cert.pem`
+(see below) is not written either, since it isn't OpenSSL's default CAfile
+on such systems in the first place.
+
+Otherwise, `/usr/lib/ssl/cert.pem` - OpenSSL's own compiled-in default
+CAfile on Debian/Ubuntu, and what apt's own https method reads absent any
+explicit configuration - is symlinked to the rebuilt bundle too. This is
+normally created by the ca-certificates package's postinst script; doing it
+here as well means the bundle is trusted even on a base image that never
+had that package installed.
+
+When `<src>` also has a RHEL/Fedora-style trust store (`/etc/pki/ca-trust`),
+the configured certificates are additionally dropped into
+`/etc/pki/ca-trust/source/anchors` and merged into
+`/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem`, the single file that
+`/etc/pki/tls/certs/ca-bundle.crt` and OpenSSL's own default CAfile
+(`/etc/pki/tls/cert.pem`) both resolve to on such systems - which is what
+dnf/curl/openssl-based tools there actually read. This intentionally does
+not reproduce the rest of `update-ca-trust extract`'s output (the OpenSSL
+"trust" bundle with per-certificate usage flags, the email/objsign bundles,
+the extracted Java keystore, ...); only the plain PEM trust bundle is

+"""Add the configured root certificates to every Java trust store detected
+under `<src>`, without shelling out to `keytool`, and configure the
+Maven-compatible repositories declared in `configurations.java.repositories`
+globally for the main JVM build tools.
+
+Java ignores the system CA store and only trusts what is in each JRE/JDK's
+own `cacerts` file: JKS format before Java 9, PKCS12 since Java 9. Every
+`cacerts` file found under `usr/` or `opt/` in `<src>` is copied into `<dst>`
+with the configured root certificates added, entirely in Python: `pyjks`
+handles the legacy JKS format, `cryptography` handles PKCS12. The default
+`changeit` store password is used, since virtually every JDK ships with it
+unchanged; a keystore that doesn't open with it is left untouched and a
+warning is logged instead of failing the whole run.
+
+The repositories are written to the well-known global configuration file of
+each build tool. Maven's is installation-wide, so every user on the image
+picks it up; the others are written under root's home directory, since this
+tool targets Docker images, which are built and run as root:
+
+- Maven3: `/etc/maven/settings.xml` (the file `/usr/share/maven/conf/settings.xml`
+  points to on Debian/Ubuntu, Maven's global, all-users settings file), plus
+  `conf/settings.xml` in every other Maven installation detected under
+  `<src>` (found via its `bin/mvn` launcher). Both get an always-active
+  profile adding every repository, plus a `mirrorOf=*` mirror on the first
+  one so that even `pom.xml` files hardcoding central are redirected.
+- Gradle: `~/.gradle/init.d/id-configurator-repositories.gradle`, an init
+  script adding the repositories to every project and to plugin management.
+- Ivy: `~/.ivy2/ivysettings.xml`, as a chain of `ibiblio` resolvers.
+- SBT: `~/.sbt/repositories`, the resolver override file SBT reads for its
+  own bootstrapping and, when combined with the `sbt.override.build.repos`
+  system property, for every project's resolvers as well.
+- Leiningen: `~/.lein/profiles.clj`, adding the repositories to the `:user`
+  profile.

+"""Ansible module wrapping id-configurator.
+
+Applies an id-configurator configuration directly to this host's live root
+filesystem, exactly like the `id_configurator` role does, but as a native
+Ansible module: it imports id-configurator's own Python API in-process
+(instead of shelling out to the CLI through a temporary file), which also
+lets it honor Ansible's check mode - reporting which modules would be
+applied without writing anything.
+
+This module is a thin, additive wrapper: it does not change anything about
+id-configurator's own behavior (the `id_configurator` Python package,
+including its module registry and every individual module, is used exactly
+as-is - the same `Configuration`, `Context` and module registry the CLI
+itself uses).

+description:
+  - Assembles the given options into an id-configurator configuration and
+    applies it directly to this host's live root filesystem, by importing
+    id-configurator's own Python API in-process (no CLI subprocess, no
+    temporary file).
+  - The option names and structure mirror id_configurator.config.Configuration
+    and id_configurator.config.ConfigurationsBlock one for one. The
+    `id_configurator` Python package must already be installed on the
+    target host, using the same Python interpreter Ansible uses there.
+  - Supports check mode - reports which modules would be applied without
+    writing anything.

+# yum-repo fixtures, used by tox-docker to exercise the `apk` module
+# integration test (tests/configs/Apk.yaml.j2,
