 Renovate authenticates as a dedicated bot user. Setup is manual on Gitea — done once per Gitea instance, then the workflow runs unattended.
 
 1. **Create a bot user.** Site Administration → Users → Create User. Suggested name: `apf-portal-bot`. Strong password, mark as **non-admin** (least privilege).
-2. **Add the bot as a collaborator** on this repo with **Write** access (Settings → Collaborators). Without write, Renovate can't push branches.
-3. **Generate a PAT for the bot.** Sign in as the bot, then User Settings → Applications → Generate New Token. Scopes needed: read/write `repository`, read/write `issue`, read `user`. Avoid `admin`.
-4. **Store the PAT as a repo secret.** Settings → Actions → Secrets → New Secret. Name: `RENOVATE_TOKEN`. Value: the token from step 3.
-5. **Sign out and forget the token locally.** It is now only retrievable via the secret store.
+2. **Set the bot's Full Name** in its Gitea profile (User Settings → Profile → Full Name, e.g. `APF Portal Bot`). Without it, Renovate's git commits fail with `empty ident name not allowed`. The `gitAuthor` in `renovate.json` is the explicit override, but keeping the profile value consistent avoids confusion when reading commit history in Gitea's UI.
+3. **Add the bot as a collaborator** on this repo with **Write** access (Settings → Collaborators). Without write, Renovate can't push branches.
+4. **Generate a PAT for the bot** (`RENOVATE_TOKEN`). Sign in as the bot, then User Settings → Applications → Generate New Token. Scopes needed: read/write `repository`, read/write `issue`, read `user`. Avoid `admin`.
+5. **Store the PAT as a repo secret.** Settings → Actions → Secrets → New Secret. Name: `RENOVATE_TOKEN`. Value: the token from step 4.
+6. **Generate a zero-scope GitHub.com PAT** (`GITHUBCOM_TOKEN`). On github.com (any account, e.g. yours): Settings → Developer settings → Personal access tokens → Tokens (classic) → Generate new token (classic). **Do not tick any scope** — anonymous-equivalent rights are enough; the token only buys Renovate the higher authenticated rate limit (5 000 req/h vs 60 req/h) for resolving GitHub-hosted Action versions and `containerbase/node-prebuild` binaries used during lockfile maintenance.
+7. **Store it as a repo secret named `GITHUBCOM_TOKEN`** (Gitea reserves the `GITHUB_*` secret namespace for the built-in `${{ github.* }}` context, so an underscore between `GITHUB` and `COM` is rejected).
+8. **Sign out and forget both tokens locally.** They are now only retrievable via the secret store.
 
-To **rotate** the PAT: regenerate at step 3, update the secret at step 4. The schedule keeps running unattended with the new token.
+To **rotate** either token: regenerate at the matching step, update the secret. The schedule keeps running unattended.
