   for history; `controller/module-map.md` is the live map and links back to it. Used additive
   cross-links rather than `git mv` because the old doc is a *planning* artifact with distinct value
   (the KEEP/PORT/DELETE rationale), not a stale copy of the new one.
-- **`controller/README.md` (controller repo):** slimmed to a build/dev quickstart that points here; the
-  architecture/feature prose now lives in `documentation/controller/`. Build instructions preserved.
+- **`controller/README.md` (controller repo):** an authoritative banner was prepended — version bumped to
+  v0.59.0, a "documentation has moved" pointer to `documentation/controller/`, the bootstrap-managed
+  deploy note, and a marker that the body is retained legacy reference. The 1987-line body was NOT
+  rewritten this session (safety over completeness — a full unattended rewrite risked garbling
+  operational/build detail). Fully slimming the body to a pure quickstart is a deferred follow-up; until
+  then the banner makes the central docs authoritative and warns the body may lag.
 - **`BUGHUNT.md` (controller repo):** added a reconciliation banner (H10 fixed, pointer to the
   reconcile record); original content preserved.
 - **`CONTEXT.md` (controller repo):** banner-and-below refreshed to v0.59.0 state.
