From 0b125830feb417f8005277c50af6194215a35970 Mon Sep 17 00:00:00 2001 From: Erik Date: Sat, 30 May 2026 17:11:02 +0200 Subject: [PATCH] =?UTF-8?q?feat(render):=20Phase=20U.2d=20=E2=80=94=20ACDR?= =?UTF-8?q?EAM=5FPROBE=5FVIS=20visibility=20probe=20in=20RenderingDiagnost?= =?UTF-8?q?ics?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add the durable per-frame visibility probe apparatus that #103 lacked, so the Phase U portal-visibility builder can be validated on live frames before any GL/visual work. EmitVis(rootCellId, visibleCells, outsidePolyCount, outsidePlaneCount, perCellPlaneCounts, scissorFallbacks) prints ONE concise [vis] line gated on root-cell CHANGE (private _lastVisRootCellId tracker; no-op when the root is unchanged or ProbeVisibilityEnabled is false — one bool compare per frame when off). Line format: [vis] root=0x… cells=N ids=[…] outside(polys=…,planes=…) percell=[0x…:N,…] fallbacks=… Reuses the existing Phase A8 ProbeVisibilityEnabled flag (env ACDREAM_PROBE_VIS, already DebugPanel-mirrored via DebugVM.ProbeVisibility) rather than adding a parallel owner — Code Structure Rule 5 (one diagnostic owner per subsystem). Property doc repurposed from the abandoned A8 two-pipe stencil semantics to the Phase U unified pipeline. Decoupling note: RenderingDiagnostics lives in AcDream.Core, which must not reference AcDream.App (Code Structure Rule 2). The plan's EmitVis signature took an App-layer CellView; this lands the equivalent as pre-computed primitives (outsidePolyCount + outsidePlaneCount) so the owner stays in Core. The U.4a call site supplies OutsideView.Polygons.Count and the OutsideView ClipPlaneSet.Count. TDD: 3 new tests in RenderingDiagnosticsVisibilityTests (no-op when disabled, fires-once-per-new-root + suppressed-on-unchanged, env-default contract), each self-contained via internal ResetVisibilityProbeForTests + Console.Out capture to avoid the documented static-leak flakiness. Core suite +3 tests, no new failures (flaky physics/input static-leak set unchanged at 16, untouched area). Courtesy: removed the dangling RenderInsideOutAcdream comment reference (deleted in U.1) + the AcDream.App.Rendering.Wb doc cref (a Core→App layer inversion). The emit SITE wiring (per-frame call from the render loop) lands in U.4a; this task lands only the owner members + formatter + test. GameWindow untouched.
