+## Unreleased
+
+### Features
+
+* **providers:** add `zero providers repair-config [--name <name>]` to recover a single legacy unnamed provider profile while preserving the legacy effective provider and active reference; identity-changing repairs of stored-key profiles refuse before writing, so they cannot point at another credential
+
+### Bug Fixes
+
+* **oauth:** validate provider configuration before authorization and immediately before token replacement across CLI, TUI, setup, and device flows, preserving existing credentials when validation fails

+If an upgraded `config.json` contains one legacy provider profile without a
+name, repair it with `zero providers repair-config`. The command preserves the
+saved `activeProvider` name (falling back to `openai`). If a row already has that
+exact name, the command preserves the field merge older releases used, with
+later nonempty fields taking precedence. An explicit `--name <unique-name>`
+keeps the legacy row separate instead. Case-only collisions and multiple
+unnamed rows are not merged by guessing; follow the error's repair guidance.

+Provider OAuth login validates the persisted user configuration before opening

+This applies to CLI login, the TUI/setup wizard, and device-code completion. If
