 3. **Gap of >10 minutes** since the last emit, via `REVIVE_REFRESH_TIME_GAP`
    (default `600` seconds).
+4. **Right after `/compact`** (or AutoCompact). The `PostCompact` hook
+   drops `.claude/revive-compact.signal` and the next refresh consumes it,
+   bypassing cadence — that's the moment the agent has lost the most
+   context, so re-injecting the brief gives the highest ROI.
+5. **Right after `/clear`**. `SessionStart` with `matcher: "clear"` drops
+   the same signal — `/clear` wipes more than `/compact`, same recovery
+   path applies.
 
 Prompts between emits see nothing from revive — silent skip, zero cost.
