+1. **Validate**:

+   ```
+2. **Update Integrity**:
+   ```sh
+   bazel run //tools:update_integrity -- <name> --version=<version>
+   ```
+3. **Overlay vs Patches**:
+   - `overlay/`: Add or overwrite files (requires `bazel_compatibility` in `MODULE.bazel`).
+   - `patches/`: Modify existing files.
+4. **Consistency**: `modules/.../MODULE.bazel` must match the source archive's version (if exists) exactly. Use an overlay/patch if they differ.

-# Gemini's Guide to Adding a Module to the Bazel Central Registry
+# Gemini's Guide to the Bazel Central Registry (BCR)
 
-This document summarizes the key learnings from adding a new module version to the Bazel Central Registry (BCR).
+This guide summarizes the essential workflows and policies for contributing to and maintaining the BCR.
 
-## 1. Initial Scaffolding
+## 📁 Repository Structure
+Each module is organized under the `modules/` directory:
+- `modules/<name>/metadata.json`: Module-level info (maintainers, versions, homepage).
+- `modules/<name>/<version>/`:
+    - `MODULE.bazel`: The module's dependency definition.
+    - `source.json`: Source archive URL, integrity (SHA-256), and optional `patches` or `overlay`.
+    - `presubmit.yml`: CI configuration (platforms, build/test targets).
+    - `patches/`: `.patch` files to modify upstream source.
+    - `overlay/`: Files to add or overwrite in the upstream source.
 
-1.  **Create the version directory**:
-    ```sh
-    mkdir -p modules/<module_name>/<version>
-    ```
-2.  **Create the `MODULE.bazel` file**: Copy from a previous version if possible and update the version number. If the module has dependencies, ensure they are correctly listed.
-3.  **Create the `source.json` file**: Copy from a previous version if possible and update the version number. This file contains the URL of the source archive, its integrity hash, and the `strip_prefix`. If the source archive doesn't contain a `MODULE.bazel` or `BUILD.bazel` file, you'll need to provide them in an `overlay`.
-4.  **Create `overlay` and `patches` directories**: If the module requires any overlays or patches, copy these directories from a previous version if they exist.
-5.  **Create `presubmit.yml`**: The validation script will fail if `modules/<module_name>/<version>/presubmit.yml` does not exist. You can usually copy this file from a previous version.
-6.  **Update `metadata.json`**: The validation script will fail if the new version is not added to the `versions` list in `modules/<module_name>/metadata.json`.
+## ⚖️ Important Policies
+- **Add-only**: The BCR is immutable. Never modify an existing version.
+- **Registry Fixes**: If a fix is registry-only (e.g., fixing compatibility with a new Bazel version), append `.bcr.<N>` to the version (e.g., `1.2.3` -> `1.2.3.bcr.1`).
+- **Bazel 9 Compatibility**: Native rules (like `cc_library`) are being removed.
+    - Add `bazel_dep(name = "rules_cc", version = "...")` to `MODULE.bazel`.
+    - Use `load("@rules_cc//cc:defs.bzl", "cc_library", ...)` in `BUILD` files via patches.
+- **Overlays**: When using `overlay/`, include `bazel_compatibility = [">=7.2.1"]` in `MODULE.bazel`.
+- **Target Names**: C++ modules should ideally expose a target with the same name as the module to allow `@module_name` syntax.
 
-## 2. Validation and Iteration
-
-*   **Validation is your best friend**: The `tools/bcr_validation.py` script is the most important tool for this process. Run it early and often. Use the `--check` flag to specify the module and version you are working on: `bazel run //tools:bcr_validation -- --check <module_name>@<version>`.
-*   **Use the `update_integrity` tool**: The `bazel run //tools:update_integrity -- <module name> --version=<version>` command is the correct way to update the integrity hashes in `source.json`.
-*   **`overlay` vs. `patches`**:
-    *   `overlay`: Use this to add or overwrite files in the downloaded source archive. The files to be overlaid should be placed in an `overlay` subdirectory within the version directory.
-    *   `patches`: Use this to apply changes to existing files in the source archive. Patch files should be placed in a `patches` subdirectory.
-*   **`MODULE.bazel` Duplication**: The `MODULE.bazel` file must exist in two places:
-    1.  At the root of the version directory (`modules/<module_name>/<version>/MODULE.bazel`).
-    2.  Inside the `overlay` directory (`modules/<module_name>/<version>/overlay/MODULE.bazel`). The file in the `overlay` directory should be a symlink to the one at the root.
-*   **`bazel_compatibility`**: When using `overlay`, the `MODULE.bazel` file must specify the `bazel_compatibility` attribute.
-
-## 3. Build Verification
-
-*   **Use the presubmit setup tool**: The `bazel run //tools:setup_presubmit_repos -- --module <module_name>@<version>` command sets up a local test environment.
-*   **Run the local build**: The output of the presubmit setup tool provides the exact `bazel build` command to run for local testing.
-*   **Clear the caches**: If you are having trouble with changes not being picked up, run `bazel clean --expunge` to clear the caches.
+## 🛠️ Essential Tools
+- `//tools:add_module`: Interactive scaffolding.
+- `//tools:update_integrity`: SHA-256 automation.
+- `//tools:bcr_validation`: Local CI check.
+- `//tools:setup_presubmit_repos`: Local build reproduction.
