 # Working Agreements
 
+## Native app versions and build numbers
+
+For every delivered change under `native/`, increment the app version and bundle/build number for the affected platforms in the same change before committing. Do this for fixes and follow-up changes too; do not wait for a separate release or a user reminder.
+
+- macOS changes require a higher macOS app version and `bundle.macOS.bundleVersion`.
+- iOS changes require a higher iOS app version and `bundle.iOS.bundleVersion`, including the matching Xcode `MARKETING_VERSION` and `CURRENT_PROJECT_VERSION` in both `project.yml` and `project.pbxproj`.
+- Shared changes require a higher general native app version and higher bundle/build numbers for every affected platform. Android changes also require a higher `bundle.android.versionCode`; this metadata rule does not imply Android build support.
+- The app version is currently shared: keep `native/package.json`, `native/src-tauri/tauri.conf.json`, the native package entries in `Cargo.toml` and `Cargo.lock`, and the Xcode marketing versions consistent. Use a patch increment unless the requested release calls for a minor or major increment. Never decrease or reuse an existing build number.
+- Update the native release notes and run the existing version consistency test. One coordinated increment per delivered change is sufficient; intermediate edits and test reruns do not need additional increments.
+
 ## Missing programs and SDKs
 
 If implementation or verification requires a missing program, SDK, runtime, toolchain, or platform component, do not download or install a temporary copy in `/tmp` or another temporary directory. Do not use an ad hoc toolchain as a workaround. Tell the user which prerequisites are missing, ask them to install them permanently and confirm when installation is complete, and wait for that confirmation before continuing dependent work. This rule applies to every implementation task in this project.
