 New constructor-acknowledgment reachability defect was independently reproduced;
 narrow core fix and separate scalar GUI implementation are active in SEM. These
 are current unresolved work, not accepted release limitations. See current STATE.

+Semantic source5/core/REST and scalar GUI are integrated at d114a5d. Full Windows718/
+Linux721 tests, strict Clippy, optimized builds and live semantic REST contracts pass.
+The equal initial discriminator acknowledgment defect is fixed and independently
+closed. Three scalar GUI P2 fixes5a51a75 are under fresh recheck/integration; structured
+authoring remains required. Basic Linux R6, middle scenario and guarded chain insertion
+have actual native evidence in their ledgers; advanced and compact cases remain.
+X11 lacks libxkbcommon-x11-0, installation requires user's sudo password. User has
+the exact fix command; Windows/Wayland progress is independent. This environment
+issue is not evidence of a semantic defect or reason to mark the release blocked.
