| 1 | """Add musehub_reflog_entries table |
| 2 | |
| 3 | Stores branch reflog entries shared from a Muse CLI client via the wire |
| 4 | protocol (muse#54 item 4). Entries are immutable history, so the natural |
| 5 | key is a content hash of every field (entry_id) rather than a mutable |
| 6 | (repo_id, branch) pointer — re-pushing the same entry is a true no-op. |
