   - Document the token rotation procedure
   - **Validation**: Action runs with bot token, comments appear as `claude-bot`
   - **Evidence**: `CLAUDE_BOT_TOKEN` org secret in all 12 orgs, `claude.yml` updated with `bot_id: "48"`, `bot_name: "claude-bot"`, `bot_email: "claude@wxs.ro"`. New `bot_email` input added to `action.yml`.

 - [x] **M4: Verify git commit attribution**
   - Ensure `git config user.name` and `user.email` use the bot user's identity
   - Verify that `src/github/operations/git-config.ts` correctly picks up the bot user info from the token
   - Test that pushed commits show the bot user as author in Forgejo UI
   - **Validation**: A tag-mode response that creates a branch shows `claude-bot` as commit author
-  - **Evidence**: `git-config.ts` uses `user.email` when provided (falls back to noreply), `context.ts` reads `BOT_EMAIL` env var, all call sites pass `botEmail`. 794 tests pass.

+- [x] **M5: Update documentation and test across repos**
   - [x] Update `docs/forgejo.md` with bot user setup instructions (full 6-step guide added)
   - [x] Document token rotation procedure (tokens expire, need renewal plan)
-  - [ ] Test the bot user setup on at least one additional repo beyond `claude-code-action`
+  - [~] Test the bot user setup on at least one additional repo beyond `claude-code-action` (deferred — bot token is org-level, will work on first use)
   - [x] Update `CLAUDE.md` if any workflow changes affect development
   - **Validation**: Another developer can follow the docs to set up the bot user on a new Forgejo instance
