+## Loose-end review — 2026-09-28
+
+Reviewed all 23 repository workplans, including archived files. The 22 closed
+workplans have no unfinished task blocks; T01 and T02 here are the only open
+tasks. Neither can complete before the upstream FLEX-WP-0020 rename lands.
+This workplan is now `blocked`, with both tasks remaining `wait`; no new tasks
+or workplans were opened.
+
+Fresh read-only probes used `curl -sS -L -o <temporary-file> -w '%{http_code}'`
+against the raw capability-index URLs listed above:
+
+- `access-engine/raw/main/registry/indexes/capabilities.yaml`: HTTP **404**.
+- `flex-auth/raw/main/registry/indexes/capabilities.yaml`: HTTP **200** after
+  following redirects.
+
+The 2026-09-20 flex-auth inbox handoff also confirms T01 must follow
+FLEX-WP-0020-T06, with the upstream owner responsible for announcing that the
+new raw index is available. The checked-in source and local roster still use
+`flex-auth`, correctly preserving the working source until that prerequisite
+is met. T02 remains blocked on T01; the hosted registration must follow the
+verified source migration. Resume these existing tasks when the canonical
+access-engine raw index is available and validates successfully.
