| `baseHeads` | current heads | `replace` and `import` only: what the new document accounts for; writes after it are carried over. |
| `settle` | 8 × keepalive | Voting period, a duration ([`configuration.md`](configuration.md), "Durations and sizes"). A short one only risks an abort for lack of votes. |
| `switchDelay` | 1 × keepalive | Wait between commit and switch, so the commit reaches every node first. Shorter only with `?force=switchDelay`. |
-| `replayWindow` | 1 epoch, 7 days | How far behind a returning node may be and still have its writes carried over automatically. |
+| `replayWindow` | 1 epoch, 7 days | How far behind a returning node may be and still have its writes carried over automatically. A remake's snapshot keeps an earlier epoch's metadata (`_continuum/epochs`) only while that still covers a node on the epoch before, and a strict remake's for good. |
| `archiveRetention` | 2 epochs, 30 days | How long nodes keep the old document. |
A retention is kept until *every* limit it gives has passed.
