+### Task 9 result — wonder-app-vd03 leg PASS (2026-08-12, deployed `20f2ae05` at 17:58, ~58 s downtime, 0 migrations)
+
+Measured as a fixed-compile-count A/B (both nodes compile an identical startup set across builds — Site 21 / Central 6 `Script<Object>` — so no forced compiles were needed on the live box):
+
+| | `5a781c70` | `20f2ae05` |
+|---|---|---|
+| Site metadata triple / `NativeHeapMemoryBlock` | 6,640 / 6,593 | **800 / 753** (8.3× / 8.8× down) |
+| Central metadata triple / `NativeHeapMemoryBlock` | 2,699 / 2,681 | **849 / 831** (3.2× down) |
+| Site / Central working set | 2,814 / 1,374 MB | 612 / 663 MB (post-fix read at ~5 min uptime — not uptime-matched; the metadata counts are the controlled result) |
+
+`CachingScriptMetadataResolver` shows exactly 1 instance per process in the gcdump — active in production. Calibration note: the steady-state residual is a **fixed** cost of roughly one shared closure set + statics (~800 for 21 scripts ≈ 38/script amortized), not the per-compile ≤~10 growth figure — the growth figure applies to *additional* compiles (rig-verified at +2/compile), the fixed cost to the startup set. Follow-up lead (not closed by this): re-test the complex `AddTemplateScript` OOM on wonder — that path was shown twice not to compile scripts, but the OOM signature (large allocation failing with GBs free) matches the native-heap state this leak produced, and the test is now cheap.
