+## Grounded backfill and live promotion
+
+The dreaming system now has two closely related review lanes:
+
+- **Live dreaming** works from the short-term dreaming store under
+  `memory/.dreams/` and is what the normal deep phase uses when deciding what
+  can graduate into `MEMORY.md`.
+- **Grounded backfill** reads historical `memory/YYYY-MM-DD.md` notes as
+  standalone day files and writes structured review output into `DREAMS.md`.
+
+Grounded backfill is useful when you want to replay older notes and inspect what
+the system thinks is durable without manually editing `MEMORY.md`.
+
+When you use:
+
+```bash
+openclaw memory rem-backfill --path ./memory --stage-short-term
+```
+
+the grounded durable candidates are not promoted directly. They are staged into
+the same short-term dreaming store the normal deep phase already uses. That
+means:
+
+- `DREAMS.md` stays the human review surface.
+- the short-term store stays the machine-facing ranking surface.
+- `MEMORY.md` is still only written by deep promotion.
+
+If you decide the replay was not useful, you can remove the staged artifacts
+without touching ordinary diary entries or normal recall state:
+
+```bash
+openclaw memory rem-backfill --rollback
+openclaw memory rem-backfill --rollback-short-term
+```

+## Dreams UI backfill and reset
+
+The Control UI Dreams scene includes **Backfill** and **Reset** actions for the
+grounded diary workflow. These actions use gateway doctor-style RPC methods, but
+they are **not** part of `openclaw doctor` CLI repair/migration.
+
+What they do:
+
+- **Backfill** scans historical `memory/YYYY-MM-DD.md` files in the active
+  workspace, runs the grounded REM diary pass, and writes reversible backfill
+  entries into `DREAMS.md`.
+- **Reset** removes only those marked backfill diary entries from `DREAMS.md`.
+
+What they do **not** do by themselves:
+
+- they do not edit `MEMORY.md`
+- they do not run full doctor migrations
+- they do not automatically stage grounded candidates into the live short-term
+  promotion store
+
+If you want grounded historical replay to influence the normal deep promotion
+lane, use the CLI flow instead:
+
+```bash
+openclaw memory rem-backfill --path ./memory --stage-short-term
+```
+
+That stages grounded durable candidates into the short-term dreaming store while
+keeping `DREAMS.md` as the review surface.
