+Checked against main on merge. Nothing in this map is built: no `texts` on
+`SourceQuery`, no chat code under `sources/`. The anchors above were corrected.
+What changed since the map was written:
+
+- Questions 1 and 2 are answered with the recommendations
+  (`gamecult-chat:ruling:chat-index-synapse-credential`, operator 2026-11-03,
+  "I take both recs."; `gamecult-chat:ruling:chat-index-room-scope`,
+  public-only). Question 3 (`chat-recall-vs-memory-ruling`) is still open.
+- **Cut 3's premise is stale.** A Persona now carries a live session under
+  bubblewrap with a shell and the web (`mind-body/src/persona.rs:53`, `--tools`;
+  rulings `persona-session-full-sandbox`, `live-mind-sessions`). She can run
+  `huginn sources` herself, so a pushed recall lane is no longer the only path.
+  Re-map cut 3 on that before it is specced: whether to push chat hits into her
+  input at all, and under which budget, is open again. Cuts 1 and 2 are
+  unaffected.
