-Roadmap
-
-- Milestone 1: Lock down capture analysis by preserving replay-shaped commands inside each observed pass, then expose counts in debug UI.
-- Milestone 2: Introduce a backend-agnostic replay IR that converts pass commands into explicit draw/clear/resolve execution packets.
-- Milestone 3: Implement the real D3D12 backend path first: device, queue, allocators, fences, frame slots, and present.
-- Milestone 4: Add guest-to-host resource translation for RTs, depth, textures, vertex/index buffers, and fetch constants.
-- Milestone 5: Add pipeline/shader translation and PSO caching, then target first visible native output from one selected pass.
-- Milestone 6: Add parity validation mode, capture-based comparisons, and rollout gates for bootstrap -> scene_submission -> parity_validation -> shipping.

-- Milestone 1 is complete.
-- Milestone 2 is now in place at the data-model level.

-Work Completed
-
-- Added a backend-agnostic observed command model with `ObservedCommandType` and `ObservedCommandDesc` in `ac6_render_frontend.h`.
-- Extended each observed pass to retain its ordered command list in `ac6_render_frontend.h`.
-- Updated frontend capture processing to materialize per-command draw, clear, and resolve records while preserving pass grouping in `ac6_render_frontend.cpp`.
-- Added `total_command_count` to the frontend summary so the runtime can report more than just pass counts.
-- Wired the frontend summary into runtime status in `ac6_native_graphics.h` and `ac6_native_graphics.cpp`.
-- Surfaced frontend pass/command counts in `ac6_native_graphics_overlay.cpp`.
-- Added a new replay IR layer in `replay_ir.h` and `replay_ir.cpp`.
-- Introduced `ReplayPassRole`, `ReplayCommandDesc`, `ReplayPassDesc`, `ReplayFrameSummary`, and `ReplayFrame`.
-- Added `ReplayIrBuilder` so the renderer can build a replay frame from frontend passes plus the frame plan.
-- Added a new execution-plan layer in `execution_plan.h` and `execution_plan.cpp`.
-- Introduced `ExecutionCommandCategory`, `ExecutionCommandPacket`, `ExecutionResourceRequirements`, `ExecutionPassPacket`, `ExecutionFrameSummary`, and `ExecutionFramePlan`.
-- Added `ExecutionPlanBuilder` so the renderer can derive backend-ready pass packets from `ReplayFrame` plus frame-plan hints.
-- Added a new replay-executor layer in `replay_executor.h` and `replay_executor.cpp`.
-- Introduced `SubmissionQueueType`, `ReplayExecutorCommandPacket`, `ReplayExecutorPassPacket`, `ReplayExecutorFrameSummary`, and `ReplayExecutorFrame`.
-- Added `ReplayExecutorPlanBuilder` so the renderer can derive submission-oriented pass packets from `ExecutionFramePlan`.
-- Added a backend executor-consumption contract in `render_device.h` and `render_device.cpp`.
-- Introduced `BackendExecutorStatus` plus backend-facing `SubmitExecutorFrame()` reporting for active backends.
-- Updated `NativeRenderer` to build replay IR first, then execution plan, then replay-executor packets, submit them to the active backend scaffold, then derive the current `RenderGraph` from executor passes.
-- Exposed replay summary data through `ac6_native_graphics.h` and `ac6_native_graphics.cpp`.
-- Exposed execution-plan summary data through `ac6_native_graphics.h` and `ac6_native_graphics.cpp`.
-- Exposed replay-executor summary data through `ac6_native_graphics.h` and `ac6_native_graphics.cpp`.
-- Exposed backend executor status through `ac6_native_graphics.h` and `ac6_native_graphics.cpp`.
-- Surfaced replay, execution, executor, and backend-consumption pass/command state in `ac6_native_graphics_overlay.cpp`.
-- Updated `CMakeLists.txt` to compile `replay_ir.cpp`, `execution_plan.cpp`, and `replay_executor.cpp`.

-Why This Matters
-
-- The renderer no longer stops at pass heuristics alone; it now carries replay IR, execution-plan, and executor artifacts forward.
-- This creates the bridge between capture analysis and future backend execution without forcing full D3D12 command-list submission too early.
-- The execution plan tracks stable per-pass resource requirements and command categories, while the replay executor shapes queue-ready submission packets and the backend scaffold now consumes them directly.
-- The D3D12 path now records submission-oriented frame, pass, resource, pipeline, and descriptor counts even before real command-list recording exists.
-- The overlay now shows whether frontend analysis, replay IR, execution planning, executor shaping, and backend consumption stay aligned frame to frame.
-
-Verification
-
-- VS Code diagnostics are clean for the edited files.
-- Full preset build verification is still blocked by an existing Ninja build-tree issue: `Re-checking globbed directories... ninja: fatal: GetOverlappedResult: The operation completed successfully.`
-- A fresh scratch configure also cannot complete in the current terminal environment because no C++ compiler is available in `PATH`.
-- I did not see source-level diagnostics from the backend-consumption scaffold changes themselves.
-
-Next Step
-
-- Replace the D3D12 scaffold `SubmitExecutorFrame()` path with real device, queue, allocator, fence, and command-list recording.
-- Add guest-to-host resource translation for executor packets: render targets, depth, textures, vertex/index buffers, and fetch constants.
-- Upgrade the current submission counters into actual PSO binding, descriptor setup, and barrier/state transitions for the selected passes.
