**Generated:** ${payload.generatedAt}

This artifact separates the five requested publication packs into:

- addresses we can honestly treat as **auto-submittable** from the repo
- addresses that are **manual or external**
- addresses that are only **inventory/reference tracking**

## Chain Summary

| Chain ID | Chain | Total Entries | Auto-submittable | Manual / External | Inventory / Reference |
| --- | --- | ---: | ---: | ---: | ---: |
${summaryRows}

## Auto-submittable backlog

| Chain ID | Chain | Label | Address | Type | Automation | Explorer Status | Next Action |
| --- | --- | --- | --- | --- | --- | --- | --- |
${autoRows}

## Manual or external backlog

| Chain ID | Chain | Label | Address | Type | Automation | Explorer Status | Next Action |
| --- | --- | --- | --- | --- | --- | --- | --- |
${manualRows}

## Closure note

For the five requested packs, the repo-owned **automatic** submission pass is complete when the auto-submittable backlog is empty.
Any remaining rows in the manual/external table require source provenance, ownership confirmation, or a non-repo verification process before they can be closed honestly.
