Tags

sekai --store ./sekai-store tag stable 1
sekai --store ./sekai-store tag stable @prev --force
sekai --store ./sekai-store tag -d stable
sekai --store ./sekai-store tag

Tags give snapshots human-readable aliases so rollback targets stay readable (rollback ./world @stable instead of an ID). Names use [A-Za-z0-9._-], run 1–64 bytes, and are never all digits, so @123 cannot be confused with snapshot 123.

• Snapshot arguments to rollback, export, and diff accept <id> or @tag; reports always carry the resolved numeric ID.
• Creating over an existing name fails unless --force moves it. Deleting a missing tag fails loudly.
• Bare tag lists all tags in name order; list shows each snapshot’s tags alongside.
• Tags are metadata only and constrain nothing: pruning a tagged snapshot drops its tags with it.
