+## 2026-06-20 Five-Axis TRT Evidence Expansion
+
+After the remaining 77 SKIP audit confirmed there are no directly promotable
+skipped main-program rows, the next evidence batch expanded browser diagnostics
+coverage for already passing representative rows instead of changing the
+inventory baseline.
+
+The virtual HAL sim-config evidence expansion report now requires these
+five-axis TRT rows:
+
+```text
+trt-boat-xyzac
+linuxcnc/configs/sim/axis/vismach/5axis/table-rotary-tilting/demos/boat-xyzac.ngc
+
+trt-xyzac-switchkins
+linuxcnc/configs/sim/axis/vismach/5axis/table-rotary-tilting/demos/xyzac_switchkins.ngc
+```
+
+Both rows use the LinuxCNC-owned `xyzac-trt.ini` machine context and the
+vendored `428remap.ngc`, `429remap.ngc`, and `430remap.ngc` remap
+subroutines. They remain:
+
+```text
+currentNodeInventoryStatus=PASS
+currentMatrixBrowserStatus=REP
+targetBrowserEvidence=browser-diagnostics-expansion
+promotionAllowed=false
+inventoryBaselineUnchanged=true
+```
+
+The real browser simulation diagnostics artifact now validates that the
+evidence expansion report has `candidateCount=5` and `readyCandidateCount=5`,
+including the two TRT rows above. The inventory baseline remains
+`executed=82 passed=82 skipped=77 unexpected_fail=0`.
