# Cubie Trust Compiler -- Intel AI Edge Application Ready Verification
# Integration Plan

================================================================================
                          EXECUTIVE SUMMARY
================================================================================

The Cubie Trust Compiler is a formally verified AI workload admission gate that
compiles to native x86_64 machine code. This document details the 5-phase plan
to integrate Cubie into Intel's AI Edge Application Ready Verification program
(Rev 2.1, Jan 2026).

What Cubie already delivers:
  - Cross-compiles to 3 bare-metal targets (RISC-V, x86_64, AArch64)
  - C-ABI entry point: extern "C" fn cubie_admit(*const CubieRequest) -> AdmitResult
  - ~730 ns/call on Intel Core Ultra 9 285HX (~1.37M admits/sec)
  - 754 theorems across Coq 8.18.0, Lean 4.30.0, and Verus
  - 62 passing integration tests, zero external dependencies
  - 3 patent families (US11956363B2, US20240195628A1)

What Intel needs from us:
  1. Application running on Intel edge hardware
  2. Workload performance metrics at light/medium/heavy loads
  3. Pipeline block diagram
  4. Resource utilization screenshots (CPU/GPU/NPU)
  5. Sizing tool report OR Appendix A alternative artifacts

The gap: No Python bindings, no C header, no container config, no OpenVINO
pipeline integration. We need a bridge from libcubie_bare_metal.a to a
Python+OpenVINO demo pipeline.

================================================================================
                WHAT A REAL INTEL EDGE AI WORKLOAD LOOKS LIKE
================================================================================

The Intel Edge AI Sizing Tool (Node.js frontend + Python FastAPI workers,
ports 5000-6000) processes workloads with these actual properties:

Workload-level properties (what gets submitted to a worker):
------------------------------------------------------------------------
  workload_id:           string    # unique identifier
  workload_type:         enum      # "dlstreamer" | "text-generation" |
                                   # "instance-segmentation" | ...
  model_name:            string    # "yolo11n", HuggingFace ID, or .xml path
  model_precision:       enum      # "FP16" | "FP32"
  device:                string    # "CPU" | "GPU" | "NPU" | "AUTO" |
                                   # "MULTI:GPU,CPU"
  batch_size:            int       # frames or tokens per inference call
  number_of_streams:     int       # parallel inference streams
  input_source:          string    # file path, RTSP URL, /dev/videoN, or text

OpenVINO compile_model config (set at model load time):
------------------------------------------------------------------------
  performance_mode:      LATENCY | THROUGHPUT
  model_priority:        LOW(0) | MEDIUM(1) | HIGH(2)
  num_streams:           int
  inference_num_threads: int
  num_requests (nireq):  int       # async request pool size
  scheduling_core_type:  ANY_CORE | PCORE_ONLY | ECORE_ONLY
  affinity:              NONE | CORE | NUMA | HYBRID_AWARE
  execution_mode:        PERFORMANCE | ACCURACY

DLStreamer pipeline element properties (per-stage in video pipelines):
------------------------------------------------------------------------
  gvadetect / gvaclassify / gvainference:
    model:               .xml path
    device:              CPU | GPU | NPU
    nireq:               parallel inference requests
    inference_interval:  process every N-th frame
    batch_size:          frames batched per call
    threshold:           detection confidence cutoff
    pre_process_backend: ie | opencv | va | va-surface-sharing

KServe V2 inference request (OVMS REST API):
------------------------------------------------------------------------
  {
    "id": "request-42",
    "inputs": [
      { "name": "input", "shape": [1,3,224,224], "datatype": "FP32" }
    ],
    "outputs": [
      { "name": "detection_output" }
    ]
  }

           MAPPING CubieRequest TO REAL WORKLOAD PROPERTIES
================================================================================

The existing CubieRequest (40 bytes, bare-metal/src/types.rs:4-25) has abstract
booleans. Here is how each field maps to real Intel Edge workload properties:

+-------------------+--------------------------------------+-------------------------------------------+

+-------------------+--------------------------------------+-------------------------------------------+
| has_valid_lease   | Lease not expired                    | lease_expiry_epoch > now()                |

+-------------------+--------------------------------------+-------------------------------------------+

|                   | batch_size + input_shape)            | truncated to u64                          |
+-------------------+--------------------------------------+-------------------------------------------+
| capability_hmac   | HMAC-SHA256 of request_hash          | Proves request authorized by platform     |

+-------------------+--------------------------------------+-------------------------------------------+
| key_slot          | Which eFuse key slot                 | 0 for single-tenant; 0-7 for multi       |

================================================================================
                    THE PIPELINE INTEGRATION POINT
================================================================================

The Cubie gate sits at WORKLOAD SUBMISSION TIME -- BEFORE core.compile_model()
or DLStreamer pipeline launch. It does NOT gate individual inference frames.
It gates whether the ENTIRE WORKLOAD is allowed to start.

  Workload Request (model, device, config)

      v
  [Policy Evaluator] -- populates CubieRequest bools from workload config
      |
      v
  [cubie_admit()] -- ~730ns, HMAC + NVLink + PCIe hardware checks
      |
      +-- Allow --> core.compile_model(model, device, config) --> inference loop
      |
      +-- Deny --> HTTP 403, workload never touches GPU/NPU

================================================================================
                  PHASE 1: FFI BRIDGE
================================================================================

Goal: Make cubie_admit() callable from Python.

Why ctypes over PyO3: Zero Python build tooling. Load .so, define struct, call
function. Minimal moving parts for a verification submission.

Why mock feature: Non-mock builds use core::ptr::read_volatile() on hardware
MMIO addresses -- this will segfault in Linux userspace. The mock feature
replaces MMIO with AtomicU32 cells. The admission logic is identical.

Files to create:
  cubie-ffi/Cargo.toml          -- cdylib, depends on cubie-bare-metal [std, mock]
  cubie-ffi/src/lib.rs          -- re-exports cubie_admit + mock setup helpers
  cubie-ffi/include/cubie.h     -- C header with static_assert(sizeof == 40)
  pipeline/cubie_gate.py        -- Python ctypes wrapper class

Modify:
  Cargo.toml (workspace root)   -- add "cubie-ffi" to members

Build:
  cargo build --release --manifest-path cubie-ffi/Cargo.toml
  # Output: target/release/libcubie_ffi.so (Linux) or cubie_ffi.dll (Windows)

Verify:
  cargo test --manifest-path bare-metal-tests/Cargo.toml  # 62 tests still pass
  python3 -c "from pipeline.cubie_gate import CubieGate; g = CubieGate(); \
    print(g.benchmark(100000))"

================================================================================
                  PHASE 2: OPENVINO PIPELINE
================================================================================

Goal: Cubie as workload admission gate in an OpenVINO inference pipeline.

Where the gate sits: At workload submission time, BEFORE core.compile_model().
Cubie decides whether a workload is allowed to load onto the GPU/NPU at all.

  Workload Request {model: "yolo11n", device: "GPU", batch_size: 2, nireq: 4}
      |
      v
  [Policy Evaluator]  -- evaluates workload config against admission rules
      |                  who: API key valid?  what: model+device allowed?
      |                  how: batch/nireq within bounds?  where: node authorized?
      |                  when: lease valid?  why: policy compliant?
      v
  [cubie_admit()]     -- ~730ns: HMAC proof-of-authorization + NVLink + PCIe
      |
      +-- Allow --> ov.Core().compile_model(model, "GPU", config) --> inference
      |
      +-- Deny  --> 403 Forbidden, zero accelerator waste

Files to create:

  pipeline/policy.py              -- Admission policy evaluator
    Takes workload request dict (model_name, device, batch_size, nireq,
    num_streams, model_precision, performance_mode, model_priority).
    Evaluates against configurable rules to produce 6 face booleans + HMAC.
    Rules:
      who:   API key in allow-list
      what:  (model_name, device) pair in approved model registry
      how:   batch_size <= 8, nireq <= 16, num_streams <= 4
      where: node_id matches deployment target
      when:  lease_expiry > time.time()
      why:   model_priority != HIGH or caller has elevated privilege

  pipeline/cubie_openvino_demo.py -- Main demo (FastAPI server)
    POST /admit   -- workload config JSON -> policy -> cubie_admit() -> Allow/Deny
    POST /launch  -- admit + compile model + run inference loop
    GET  /metrics -- admit/deny counts, latencies, resource utilization
    GET  /health  -- service health

  pipeline/load_profiles.py       -- Load generator (Intel's 3-level requirement)
    Light:  1 workload/sec, single model, CPU-only
    Medium: 5 concurrent workloads, CPU+GPU, varied batch sizes
    Heavy:  max concurrent, all devices, stress test gate throughput

  pipeline/resource_monitor.py    -- Resource monitoring
    psutil for CPU/memory, xpumcli for GPU, sysfs for NPU
    1s sampling interval, CSV output, 5s idle baseline subtraction

  pipeline/requirements.txt       -- Python dependencies
    openvino>=2024.0, fastapi>=0.110, uvicorn>=0.29,
    psutil>=5.9, matplotlib>=3.7, numpy>=1.24

  pipeline/models.json            -- Approved model registry (policy config)
    Lists allowed (model_name, device, max_batch, max_nireq) tuples

How policy.py populates CubieRequest from real workload properties:
------------------------------------------------------------------------

  def evaluate_workload(workload, policy, gate):
      # 6-face evaluation against real workload properties
      who   = workload["api_key"] in policy["allowed_keys"]
      what  = (workload["model_name"], workload["device"]) in policy["approved_models"]
      how   = (workload["batch_size"] <= policy["max_batch"]
               and workload["nireq"] <= policy["max_nireq"])
      where = workload.get("node_id", "local") in policy["authorized_nodes"]
      when  = workload.get("lease_expiry", float("inf")) > time.time()
      why   = (workload.get("model_priority", 1) <= policy["max_priority"]
               or workload.get("elevated", False))

      # Compute request hash from workload config
      config_str = f"{workload['model_name']}:{workload['device']}:{workload['batch_size']}"
      request_hash = int.from_bytes(
          hashlib.sha256(config_str.encode()).digest()[:8], "big"
      )

      # Build CubieRequest with real data
      req = CubieRequest(
          who_pass=who, what_pass=what, how_pass=how,
          where_pass=where, when_pass=when, why_pass=why,
          has_valid_lease=when,
          epoch_fresh=True,
          request_hash=request_hash,
          capability_hmac=gate.compute_hmac(request_hash),
          key_slot=0, peer_id=0,
          adapter_id=get_pcie_adapter_id(workload["device"]),
      )
      return gate.admit(req)

Model setup:
  pip install openvino-dev
  omz_downloader --name yolo-v8 --output_dir models/
  omz_converter --name yolo-v8 --output_dir models/

  # Or text generation fallback:
  pip install openvino-genai

Application name:
  "Cubie Trust Compiler -- Formally Verified AI Admission Gate"

Narrative for Intel review meeting:

  The Cubie Trust Compiler is the first formally verified AI workload admission
  gate. It runs as a sub-microsecond pre-inference filter on Intel edge
  hardware, making admission decisions in ~730 nanoseconds -- proven correct by
  754 independent theorems across three proof assistants (Coq, Lean 4, Verus).
  Every AI inference request passes through the gate before consuming GPU or
  NPU compute. Denied requests use zero accelerator resources. The entire stack
  compiles to native x86_64 machine code with zero external dependencies.
  Protected by 3 patent families (US11956363B2, US12073439B2,
  US20240195628A1).

# Cubie Trust Compiler -- Intel AI Edge Application Ready Verification
# Integration Plan

================================================================================
                          EXECUTIVE SUMMARY
================================================================================

The Cubie Trust Compiler is a formally verified AI workload admission gate that
compiles to native x86_64 machine code. This document details the 5-phase plan
to integrate Cubie into Intel's AI Edge Application Ready Verification program
(Rev 2.1, Jan 2026).

What Cubie already delivers:
  - Cross-compiles to 3 bare-metal targets (RISC-V, x86_64, AArch64)
  - C-ABI entry point: extern "C" fn cubie_admit(*const CubieRequest) -> AdmitResult
  - ~730 ns/call on Intel Core Ultra 9 285HX (~1.37M admits/sec)
  - 754 theorems across Coq 8.18.0, Lean 4.30.0, and Verus
  - 62 passing integration tests, zero external dependencies
  - 3 patent families (US11956363B2, US20240195628A1)

What Intel needs from us:
  1. Application running on Intel edge hardware
  2. Workload performance metrics at light/medium/heavy loads
  3. Pipeline block diagram
  4. Resource utilization screenshots (CPU/GPU/NPU)
  5. Sizing tool report OR Appendix A alternative artifacts

The gap: No Python bindings, no C header, no container config, no OpenVINO
pipeline integration. We need a bridge from libcubie_bare_metal.a to a
Python+OpenVINO demo pipeline.

================================================================================
                WHAT A REAL INTEL EDGE AI WORKLOAD LOOKS LIKE
================================================================================

The Intel Edge AI Sizing Tool (Node.js frontend + Python FastAPI workers,
ports 5000-6000) processes workloads with these actual properties:

Workload-level properties (what gets submitted to a worker):
------------------------------------------------------------------------
  workload_id:           string    # unique identifier
  workload_type:         enum      # "dlstreamer" | "text-generation" |
                                   # "instance-segmentation" | ...
  model_name:            string    # "yolo11n", HuggingFace ID, or .xml path
  model_precision:       enum      # "FP16" | "FP32"
  device:                string    # "CPU" | "GPU" | "NPU" | "AUTO" |
                                   # "MULTI:GPU,CPU"
  batch_size:            int       # frames or tokens per inference call
  number_of_streams:     int       # parallel inference streams
  input_source:          string    # file path, RTSP URL, /dev/videoN, or text

OpenVINO compile_model config (set at model load time):
------------------------------------------------------------------------
  performance_mode:      LATENCY | THROUGHPUT
  model_priority:        LOW(0) | MEDIUM(1) | HIGH(2)
  num_streams:           int
  inference_num_threads: int
  num_requests (nireq):  int       # async request pool size
  scheduling_core_type:  ANY_CORE | PCORE_ONLY | ECORE_ONLY
  affinity:              NONE | CORE | NUMA | HYBRID_AWARE
  execution_mode:        PERFORMANCE | ACCURACY

DLStreamer pipeline element properties (per-stage in video pipelines):
------------------------------------------------------------------------
  gvadetect / gvaclassify / gvainference:
    model:               .xml path
    device:              CPU | GPU | NPU
    nireq:               parallel inference requests
    inference_interval:  process every N-th frame
    batch_size:          frames batched per call
    threshold:           detection confidence cutoff
    pre_process_backend: ie | opencv | va | va-surface-sharing

KServe V2 inference request (OVMS REST API):
------------------------------------------------------------------------
  {
    "id": "request-42",
    "inputs": [
      { "name": "input", "shape": [1,3,224,224], "datatype": "FP32" }
    ],
    "outputs": [
      { "name": "detection_output" }
    ]
  }

           MAPPING CubieRequest TO REAL WORKLOAD PROPERTIES
================================================================================

The existing CubieRequest (40 bytes, bare-metal/src/types.rs:4-25) has abstract
booleans. Here is how each field maps to real Intel Edge workload properties:

+-------------------+--------------------------------------+-------------------------------------------+

+-------------------+--------------------------------------+-------------------------------------------+
| who_pass          | IDENTITY: Is the requesting entity   | Check API key, JWT, or mTLS cert          |
|                   | (user/service/container) authed?     | against allow-list                        |
+-------------------+--------------------------------------+-------------------------------------------+
| what_pass         | CAPABILITY: Is this model+precision  | Validate model_name + model_precision +   |

+-------------------+--------------------------------------+-------------------------------------------+
| when_pass         | LEASE: Is the time-bounded           | Check lease_expiry > current_time         |

+-------------------+--------------------------------------+-------------------------------------------+
| why_pass          | POLICY: Does the workload comply     | Check model_priority, performance_mode,   |
|                   | with governance rules?               | resource quotas                           |
+-------------------+--------------------------------------+-------------------------------------------+
| has_valid_lease   | Lease not expired                    | lease_expiry_epoch > now()                |

+-------------------+--------------------------------------+-------------------------------------------+
| request_hash      | Hash of (model_name + device +       | SHA-256 of workload config fields,        |
|                   | batch_size + input_shape)            | truncated to u64                          |
+-------------------+--------------------------------------+-------------------------------------------+
| capability_hmac   | HMAC-SHA256 of request_hash          | Proves request authorized by platform     |

+-------------------+--------------------------------------+-------------------------------------------+
| key_slot          | Which eFuse key slot                 | 0 for single-tenant; 0-7 for multi       |

+-------------------+--------------------------------------+-------------------------------------------+
| adapter_id        | PCIe adapter for bandwidth check     | Maps to GPU/NPU PCIe device ID            |

================================================================================
                    THE PIPELINE INTEGRATION POINT
================================================================================

The Cubie gate sits at WORKLOAD SUBMISSION TIME -- BEFORE core.compile_model()
or DLStreamer pipeline launch. It does NOT gate individual inference frames.
It gates whether the ENTIRE WORKLOAD is allowed to start.

  Workload Request (model, device, config)
      |
      v
  [Policy Evaluator] -- populates CubieRequest bools from workload config
      |
      v
  [cubie_admit()] -- ~730ns, HMAC + NVLink + PCIe hardware checks
      |
      +-- Allow --> core.compile_model(model, device, config) --> inference loop
      |
      +-- Deny --> HTTP 403, workload never touches GPU/NPU

================================================================================
                  PHASE 1: FFI BRIDGE
================================================================================

Goal: Make cubie_admit() callable from Python.

Why ctypes over PyO3: Zero Python build tooling. Load .so, define struct, call
function. Minimal moving parts for a verification submission.

Why mock feature: Non-mock builds use core::ptr::read_volatile() on hardware
MMIO addresses -- this will segfault in Linux userspace. The mock feature
replaces MMIO with AtomicU32 cells. The admission logic is identical.

Files to create:
  cubie-ffi/Cargo.toml          -- cdylib, depends on cubie-bare-metal [std, mock]
  cubie-ffi/src/lib.rs          -- re-exports cubie_admit + mock setup helpers
  cubie-ffi/include/cubie.h     -- C header with static_assert(sizeof == 40)
  pipeline/cubie_gate.py        -- Python ctypes wrapper class

Modify:
  Cargo.toml (workspace root)   -- add "cubie-ffi" to members

Build:
  cargo build --release --manifest-path cubie-ffi/Cargo.toml
  # Output: target/release/libcubie_ffi.so (Linux) or cubie_ffi.dll (Windows)

Verify:
  cargo test --manifest-path bare-metal-tests/Cargo.toml  # 62 tests still pass
  python3 -c "from pipeline.cubie_gate import CubieGate; g = CubieGate(); \
    print(g.benchmark(100000))"

================================================================================
                  PHASE 2: OPENVINO PIPELINE
================================================================================

Goal: Cubie as workload admission gate in an OpenVINO inference pipeline.

Where the gate sits: At workload submission time, BEFORE core.compile_model().
Cubie decides whether a workload is allowed to load onto the GPU/NPU at all.

  Workload Request {model: "yolo11n", device: "GPU", batch_size: 2, nireq: 4}
      |
      v
  [Policy Evaluator]  -- evaluates workload config against admission rules
      |                  who: API key valid?  what: model+device allowed?
      |                  how: batch/nireq within bounds?  where: node authorized?
      |                  when: lease valid?  why: policy compliant?
      v
  [cubie_admit()]     -- ~730ns: HMAC proof-of-authorization + NVLink + PCIe
      |
      +-- Allow --> ov.Core().compile_model(model, "GPU", config) --> inference
      |
      +-- Deny  --> 403 Forbidden, zero accelerator waste

Files to create:

  pipeline/policy.py              -- Admission policy evaluator
    Takes workload request dict (model_name, device, batch_size, nireq,
    num_streams, model_precision, performance_mode, model_priority).
    Evaluates against configurable rules to produce 6 face booleans + HMAC.
    Rules:
      who:   API key in allow-list
      what:  (model_name, device) pair in approved model registry
      how:   batch_size <= 8, nireq <= 16, num_streams <= 4
      where: node_id matches deployment target
      when:  lease_expiry > time.time()
      why:   model_priority != HIGH or caller has elevated privilege

  pipeline/cubie_openvino_demo.py -- Main demo (FastAPI server)
    POST /admit   -- workload config JSON -> policy -> cubie_admit() -> Allow/Deny
    POST /launch  -- admit + compile model + run inference loop
    GET  /metrics -- admit/deny counts, latencies, resource utilization
    GET  /health  -- service health

  pipeline/load_profiles.py       -- Load generator (Intel's 3-level requirement)
    Light:  1 workload/sec, single model, CPU-only
    Medium: 5 concurrent workloads, CPU+GPU, varied batch sizes
    Heavy:  max concurrent, all devices, stress test gate throughput

  pipeline/resource_monitor.py    -- Resource monitoring
    psutil for CPU/memory, xpumcli for GPU, sysfs for NPU
    1s sampling interval, CSV output, 5s idle baseline subtraction

  pipeline/requirements.txt       -- Python dependencies
    openvino>=2024.0, fastapi>=0.110, uvicorn>=0.29,
    psutil>=5.9, matplotlib>=3.7, numpy>=1.24

  pipeline/models.json            -- Approved model registry (policy config)
    Lists allowed (model_name, device, max_batch, max_nireq) tuples

How policy.py populates CubieRequest from real workload properties:
------------------------------------------------------------------------

  def evaluate_workload(workload, policy, gate):
      # 6-face evaluation against real workload properties
      who   = workload["api_key"] in policy["allowed_keys"]
      what  = (workload["model_name"], workload["device"]) in policy["approved_models"]
      how   = (workload["batch_size"] <= policy["max_batch"]
               and workload["nireq"] <= policy["max_nireq"])
      where = workload.get("node_id", "local") in policy["authorized_nodes"]
      when  = workload.get("lease_expiry", float("inf")) > time.time()
      why   = (workload.get("model_priority", 1) <= policy["max_priority"]
               or workload.get("elevated", False))

      # Compute request hash from workload config
      config_str = f"{workload['model_name']}:{workload['device']}:{workload['batch_size']}"
      request_hash = int.from_bytes(
          hashlib.sha256(config_str.encode()).digest()[:8], "big"
      )

      # Build CubieRequest with real data
      req = CubieRequest(
          who_pass=who, what_pass=what, how_pass=how,
          where_pass=where, when_pass=when, why_pass=why,
          has_valid_lease=when,
          epoch_fresh=True,
          request_hash=request_hash,
          capability_hmac=gate.compute_hmac(request_hash),
          key_slot=0, peer_id=0,
          adapter_id=get_pcie_adapter_id(workload["device"]),
      )
      return gate.admit(req)

Model setup:
  pip install openvino-dev
  omz_downloader --name yolo-v8 --output_dir models/
  omz_converter --name yolo-v8 --output_dir models/

  # Or text generation fallback:

Application name:
  "Cubie Trust Compiler -- Formally Verified AI Admission Gate"

Narrative for Intel review meeting:

  The Cubie Trust Compiler is the first formally verified AI workload admission
  gate. It runs as a sub-microsecond pre-inference filter on Intel edge
  hardware, making admission decisions in ~730 nanoseconds -- proven correct by
  754 independent theorems across three proof assistants (Coq, Lean 4, Verus).
  Every AI inference request passes through the gate before consuming GPU or
  NPU compute. Denied requests use zero accelerator resources. The entire stack
  compiles to native x86_64 machine code with zero external dependencies.
  Protected by 3 patent families (US11956363B2, US12073439B2,
  US20240195628A1).

                  END-TO-END VERIFICATION
================================================================================

  1. cargo test --manifest-path bare-metal-tests/Cargo.toml
     -- 62 tests pass (no regression)

  2. cargo build --release --manifest-path cubie-ffi/Cargo.toml
     -- .so/.dll builds

  3. python3 -c "from pipeline.cubie_gate import CubieGate; \
       g = CubieGate(); print(g.admit(g.create_test_request()))"
     -- prints True

  4. Policy evaluation test:
     Submit workload: model_name="yolo11n", device="GPU", batch_size=2
       against a policy that allows it -> returns Allow
     Change device="INVALID" -> returns Deny (what_pass fails)
     Change batch_size=999 -> returns Deny (how_pass fails)

  5. python3 pipeline/cubie_openvino_demo.py --mode light --duration 10
     -- runs without error, logs admit/deny with ns latencies

  6. python3 pipeline/generate_diagrams.py --output artifacts/
     -- produces PNGs

  7. All artifacts in artifacts/ directory are non-empty and submission-ready
