docs(architecture): close GameWindow render slice

Record the clean Release, lifecycle, soak, and framebuffer gates for Slice 7, advance the structural program to Slice 8, and preserve the observed process-residency diagnostic gap as issue 232 rather than weakening its leak threshold.\n\nCo-authored-by: Codex <codex@openai.com>

+## #232 — Nine-stop soak process-memory gate lacks canonical owner snapshots
+
+**Status:** OPEN
+**Severity:** LOW
+**Filed:** 2026-07-22
+**Component:** connected automation / resource diagnostics
+
+**Description:** Identical-binary nine-stop runs can cross the same-location
+working/private-process-memory tolerance even when all deterministic lifecycle,
+entity, animation, allocation-rate, update-cost, movement, and graceful-close
+checks pass. At Slice 7 closeout, two runs reported Caul-plateau working-set
+growth of +240.9 MiB and +497.4 MiB; a third unchanged run passed at +85.7 MiB
+(private +59.3 MiB). Earlier Slice 6 development history also contains both a
+coarse-memory failure and subsequent clean runs.
+
+**Root cause / status:** The current soak samples only process working set and
+private bytes plus coarse world/title counters. Those totals combine live .NET
+objects, committed-but-free GC segments, native allocations, mapped pages, and
+GPU-driver residency, so a failed total cannot identify the owner that grew.
+This is a diagnostic blind spot, not evidence that the threshold should be
+raised. The unchanged gate produced a clean required closeout pass; no runtime
+workaround or tolerance change was made.
+
+**Files:** `tools/run-connected-r6-soak.ps1`;
+`src/AcDream.App/Diagnostics/WorldLifecycleAutomationController.cs`;
+`src/AcDream.App/Rendering/RenderFrameDiagnosticsController.cs`.
+
+**Acceptance:** Each named soak checkpoint records the existing canonical
+world-lifecycle resource snapshot (managed used/committed, tracked GPU buffers
+and textures, mesh/atlas caches, composite/particle texture ownership, VFX and
+pending teardown counts). Same-location assertions identify which owner grew;
+process residency remains a secondary guard. Repeated clean runs pass without
+loosening the canonical-owner leak limits.

 **Purpose:** One source of truth for where the project is and where it's going. Every observed defect or missing feature has a named phase that owns it; when something looks wrong in-game, look here to find the phase that'll address it. Implementation details live in per-phase specs under `docs/superpowers/specs/`, not in this file.
