结论：已完成剩余77个SKIP的promotion复核；仅2个main SKIP且promotion_allowed均为0，当前baseline保持82/82/77/0，并新增文档与docs smoke防止误promotion。

+## 2026-06-20 Remaining Skip Promotion Audit
+
+The generated audit for the remaining 77 skipped rows is:
+
+```text
+build/wasm/sim-configs-inventory/remaining-skip-main-program-promotion-audit.tsv
+```
+
+It contains only two skipped rows whose class is `main`:
+
+| Path | Skip kind | Native status | Promotion allowed | Decision |
+| --- | --- | --- | ---: | --- |
+| `axis/vismach/5axis/table-rotary_spindle-rotary-nutating/demos/incremental_repetition_g533.ngc` | `UPSTREAM-DEMO` | `FAIL` with `upstream-demo-missing-motion-gcode` | 0 | Preserve as an upstream demo edge; do not force into PASS. |
+| `axis/vismach/millturn/example.ngc` | `L4-USER-M-PROCESS` | `PASS` | 0 | Web virtual HAL proof exists for M428/M429 to M128/M129 transition state, but arbitrary external user-M process execution remains disabled and is not an inventory promotion proof. |
+
+The remaining skipped rows are not direct main-program promotion targets:
+
+```text
+ASSET-ONLY=65
+NON_MAIN_CLASS=10
+```
+
+The 2026-06-20 audit conclusion is therefore explicit:
+
+```text
+remaining_skip_count=77
+remaining_skipped_main_program_rows=2
+remaining_skipped_main_program_promotion_allowed=0
+direct_inventory_promotion_rows=0
+baseline_change_allowed=no
+```
+
+Future work should add browser diagnostics and release evidence for already
+passing Node inventory or representative rows. It should not change the
+inventory baseline unless a later patch supplies LinuxCNC-owned native proof,
+Node/WASM proof, browser proof, and a manual promotion-lock update for the row
+being promoted.
