First application of CLAUDE.md's new Code Structure Rules §5
("Runtime probes belong in diagnostic owner classes"). Migrates the
four ACDREAM_DUMP_STEEP_ROOF call-site env reads into a single
PhysicsDiagnostics.DumpSteepRoofEnabled property initialized from the
env var at type init, with a runtime setter that follows the existing
ProbeResolveEnabled / ProbeCellEnabled / ProbeBuildingEnabled pattern.
Sites migrated:
- AcDream.Core/Physics/PhysicsEngine.cs:637 (KILL-VELOCITY-APPLIED log)
- AcDream.Core/Physics/TransitionTypes.cs:718 (PHASE3-RESET log)
- AcDream.App/Input/PlayerMovementController.cs:1117 (FRAME log)
- AcDream.App/Input/PlayerMovementController.cs:1199 (per-frame bounce log)
Behavior-preservation only. ACDREAM_DUMP_STEEP_ROOF=1 still produces
identical [steep-roof] log output. The class-comment in
PhysicsDiagnostics already anticipated this migration
("Future slices may fold the older ACDREAM_DUMP_* env vars into this
class for unified runtime toggling").
Not yet wired to a DebugVM checkbox — runtime toggling is available
via the property setter for future debugging sessions, but exposing
it on the panel is a 30-second future cut, not in scope here.
Build: green.
Tests: same pass/fail profile as before this commit (8 pre-existing
Core failures unrelated to physics-diagnostics; App.Tests / Core.Net.Tests
/ UI.Abstractions.Tests all green).
