 - Added `src/tools/capture_render_checkpoints.gd` to load the Eastern Kingdoms streaming scene, move a dedicated camera to fixed regression viewpoints and save PNGs under `user://render_checkpoints`.
 - Current checkpoints cover the Elwynn waterfall from front/side and Goldshire Inn/Blacksmith windows. Headless runs are dry-run only because the headless display server cannot produce viewport PNGs.
 
+## 2026-07-13 Renderer Shutdown Ownership
+
+- `StreamingWorldLoader` drains its asynchronous work before teardown, leaves parented streamed nodes to SceneTree ownership, then explicitly frees detached M2/WMO prototype nodes and clears resource caches.
+- `ADTBuilder` explicitly frees a temporary `Water` root when an ADT liquid payload produces no child geometry. Dry tiles must not leave empty nodes in ObjectDB.
+- `src/tools/verify_render_runtime_cache_shutdown.gd` regression-checks detached prototype and resource-cache release plus empty-liquid-root ownership. The unified render-baseline runner executes it before capture.
+- A focused 8-second GUI checkpoint and a seven-checkpoint single-pass GUI run finish without Node, renderer resource or RID leak diagnostics. A timing-dependent anonymous zero-reference `RefCounted` ObjectDB warning can remain at engine teardown; it is tracked separately and is not suppressed.
+- This is shutdown-only ownership behavior and does not alter checkpoint rendering, cache formats or the `Blizzlike335` compatibility profile.
+
 ## Practical Rule For Future Work
 
 If something improves quality but creates visible hitch, it is not done. Move it to bake/cache/background work, split finalization over frames, or prewarm it before the player can see it.

+# M00 Final Paired Evidence — 2026-07-13
+
+## Scope and result
+
+The final local M00 audit used Godot 4.6.1, the existing cache state, the manifest-standard 8-second readiness wait, and `2560x1440` visual candidates. Seven private WoW 3.3.5a build 12340 references produced fourteen cold/warm comparisons with no missing pair. Private images and generated reports remain outside Git.
+
+Every pair exceeded the strict regression tolerance. Comparator exit code `1` means a valid report with measured visual gaps; only codes outside `0/1` are infrastructure failures. This evidence establishes coverage and current differences, not renderer parity.
+
+```powershell
+.\tools\run_render_baseline.ps1 `
+  -Output user://render_baseline_m00_complete_2026-07-13 `
+  -CacheState existing `
+  -WaitSeconds 8 `
+  -MeasureSeconds 0.5 `
+  -ReferenceCheckpointDirectory .\sources\OpenWCReferenceCheckpoints `
+  -VisualComparisonReport user://render_baseline_m00_complete_2026-07-13/visual_comparison.json `
+  -VisualComparisonWidth 2560 `
+  -VisualComparisonHeight 1440
+```
+
+The initial shell timeout detached the canonical capture process after it started. The process completed all fourteen canonical captures and wrote `report.json`; the documented visual-capture and comparator stages were then invoked separately with the same arguments. The final output directory contains both complete reports.
+
+## Paired metrics
+
+| Checkpoint | Pass | Mean perceptual error | Changed-pixel ratio | Classification |
+|---|---|---:|---:|---|
+| `elwynn_adt_boundary` | cold | 0.087258 | 0.634580 | Composition plus terrain/vegetation/material gaps |
+| `elwynn_adt_boundary` | warm | 0.087255 | 0.634598 | Stable against revisit |
+| `elwynn_sky_dusk` | cold | 0.094778 | 0.575956 | Approximate paired camera; sky color, lighting and scene-composition gaps |
+| `elwynn_sky_dusk` | warm | 0.094757 | 0.575898 | Stable against revisit |
+| `elwynn_terrain_overview` | cold | 0.174137 | 0.851791 | Largest composition/framing gap |
+| `elwynn_terrain_overview` | warm | 0.176955 | 0.861271 | Stable gap, not a cold-load artifact |
+| `elwynn_waterfall_liquid` | cold | 0.088629 | 0.706522 | Framing, terrain, liquid and lighting gaps |
+| `elwynn_waterfall_liquid` | warm | 0.087398 | 0.693690 | Stable against revisit |
+| `goldshire_dense_m2` | cold | 0.066893 | 0.575257 | Smallest available paired gap; vegetation/material differences remain |
+| `goldshire_dense_m2` | warm | 0.066927 | 0.575592 | Stable against revisit |
+| `goldshire_inn_large_wmo` | cold | 0.101224 | 0.701835 | WMO is ready; manual framing and presentation gaps remain |
+| `goldshire_inn_large_wmo` | warm | 0.101206 | 0.701855 | Stable against revisit |
+| `gryphon_roost_native_animation` | cold | 0.119467 | 0.882073 | Same build-12340 asset, different real/synthetic placement and uncontrolled animation phase |
+| `gryphon_roost_native_animation` | warm | 0.119471 | 0.882076 | Full-frame metric is diagnostic only; animation observation is human evidence |
+
+Cold and warm values are close for all seven references. The measured gaps are therefore not explained by first-visit cache readiness. Goldshire timing evidence separately demonstrated that the 8-second wait is necessary for WMO publication.
+
+## Animation and sky provenance
+
+The private source corpus preserves exact screenshot bytes; no resize, crop or generated content was used:
+
+| Evidence | SHA-256 | Interpretation |
+|---|---|---|
+| `elwynn_sky_dusk.jpg` | `1fb06836cacae714c76eaf9b8bf7c292fd5e2f2df33eef821bfe4c4a6bd97072` | Build 12340, Elwynn camera position, server time approximately 19:00, UI hidden |
+| `gryphon_roost_native_animation.jpg` | `d3488c741cb8dfe7212198e48332842631a951862a4388b67045338f37357447` | Build 12340 real-world `GryphonRoost01` placement, first visible wing phase |
+| diagnostic animation phase B | `1025572c7ab9fa0d2e500ff026be46eb9c1e6e5447116dbdc3675dd5f44574ab` | Same camera three seconds later; visibly raised wing phase |
+| diagnostic placement context | `b12c0b713a7d75123ed30f5a316b33537331442cd56615aea69214c7cc4e7a42` | Two real Lakeshire placements and surrounding build-12340 scene |
+
+An ADT scan found no `GryphonRoost01` placement in Goldshire. The M00 checkpoint deliberately injects the model there as a synthetic probe. The original-client observation therefore uses two real Lakeshire placements. The three-second pose change establishes `Observed` native animation behavior, but the full-frame comparison cannot establish spatial or animation-phase parity.
+

+M00 now has private build 12340 evidence for every required coverage category: terrain, ADT boundary, dense M2, large WMO, liquid, animated M2 and sky transition. The sky reference is approximately paired by map position/time and manually approved composition. Animated-M2 evidence is asset-paired but placement-unpaired because the OpenWC probe is synthetic.
+
+The reports demonstrate current differences and do not claim `1:1`. Camera calibration experiments also show that unknown manual yaw/pitch/FOV cannot be recovered reliably from full-frame color error alone. Region scoring reduces terrain bias but still requires semantic landmark approval.
+
+## Operational risks
+
+A follow-up shutdown ownership fix removed the GUI renderer leaks found by the final visual capture. Before the fix, the focused animated-M2 checkpoint retained 6 mesh, 6 material, 4 shader, 6 texture, 6 instance and associated RenderingDevice RIDs, for 30 resources in use. After the fix, both the focused 8-second capture and a seven-checkpoint single-pass capture completed without Node, resource or RID leak diagnostics.
+
+Godot can still emit a timing-dependent ObjectDB warning for one or more anonymous `RefCounted` objects whose reported reference count is already zero. The warning has no retained Node, renderer resource or RID ownership in the verified captures. It remains recorded as an engine-teardown diagnostic rather than being hidden, but it is distinct from the resolved GUI renderer leak.
+
+## Integrator decision checklist
+
+- Seven required reference checkpoints: cold/warm report complete, `compared=14`, `missing=0`.
+- Animated M2: build-12340 native motion observed in two phases; synthetic/real placement mismatch explicitly classified.
+- Sky transition: build-12340 19:00 evidence present with approximate paired camera and human-approved composition.
+- Renderer visual differences: registered as gaps, not parity claims.
+- GUI renderer RID/resource diagnostics: resolved by explicit shutdown ownership and covered by a headless regression verifier; the residual zero-reference `RefCounted` engine-teardown warning remains tracked separately.
+- Target status, target Evidence and `OPENWC_TARGET_DONE` marker: integrator-only actions.

-- Results: headless load, renderer material smoke, M2 unique-id dedupe and manifest contract passed. Full run produced 14 PNGs and 14 result records for 7 cold/warm checkpoints. Actual renderer was Godot 4.6.1, Vulkan Forward+, NVIDIA RTX 5070, 1280x900, High profile, with all seven cache families present. Cold p95 range was 31.585..86.537 ms with max hitch 258.456 ms; warm p95 range was 18.824..38.085 ms with max hitch 163.363 ms. The final streaming snapshots had an empty tile queue. Report: `user://render_baseline_m00_2026-07-10/report.json`.

-- Remaining risks: original-client paired comparison is still required before DONE; D3D12 descriptor heap creation failed and the measured run fell back to Vulkan; shutdown reported leaked renderer RIDs/resources; current captures intentionally preserve visible terrain/placement/material/animation gaps, including the synthetic native animated M2 probe; perceptual image diff/tolerance is documented but not automated yet.

+- Fidelity comparison: private original-client WoW 3.3.5a build 12340 references cover terrain, ADT boundary, dense M2, large WMO, liquid, animated M2 and sky transition. Every measured pair exceeds the strict visual tolerance and is recorded as a current gap rather than parity. Sky framing is approximately paired; animated M2 is asset-paired but placement-unpaired because the OpenWC Goldshire probe is synthetic.

+- Remaining risks: renderer parity is not claimed; documented terrain/material/placement/animation/lighting/liquid/culling gaps remain future renderer work. D3D12 descriptor heap creation can fall back to Vulkan. Godot can emit a timing-dependent anonymous zero-reference `RefCounted` teardown warning without retained Node/resource/RID ownership.
