+# Feed Intelligence memory profile example
+
+Status: example-only contract
+
+This example applies the existing Slash Topic memory profile posture to the canonical SocioProphet Feed Intelligence reader.
+
+Canonical reader surface:
+
+```text
+SocioProphet/socioprophet/socioprophet-web/client-vue
+```
+
+Related upstream examples:
+
+```text
+SocioProphet/slash-topics/examples/feed-intelligence/scope.example.md
+SocioProphet/new-hope/examples/feed-intelligence/membrane-event.example.md
+```
+
+## Purpose
+
+MemoryMesh attaches after SlashTopics scope resolution and New Hope membrane admission. The Feed Intelligence reader can display memory posture, but it must not silently write durable memory from feed items, browser captures, annotations, summaries, or graph views.
+
+## Example profile

+```
+
+## Boundary rules
+
+- MemoryMesh may provide scoped recall posture after topic and membrane resolution.
+- Raw sensitive payload storage remains disallowed by default.
+- Dry-run mode performs no recall backend call and no writeback.
+- Writeback remains disabled until a later explicit governance flow approves it.
+- Feed item display, browser capture, and graph preparation do not imply durable memory promotion.
+
+## Acceptance posture
+
+This example is acceptable while it remains a non-runtime memory-profile example. It must not claim live recall, writeback, promotion, embedding jobs, or durable memory storage.
