AI-Assisted Compilation via DSMIL Layers 3–9 + +The DSMIL AI architecture provides rich AI capabilities per layer (LLMs in Layer 7, security AI in Layer 8, strategic planners in Layer 9, predictive analytics in Layers 4–6). + +DSLLVM uses these as **external advisors** via a defined request/response protocol. + +### 8.1 AI Advisor Overview + +DSLLVM can emit **AI advisory requests**: + +* Input: + + * Summaries of modules/IR (statistics, CFG features). + * Existing DSMIL metadata (`layer`, `device`, `stage`, `bw_estimate`). + * Current build goals (latency targets, power budgets, security posture). + +* Output (AI suggestions): + + * Suggested `dsmil_stage`, `dsmil_layer`, `dsmil_device` annotations. + * Pass pipeline tuning (e.g., "favor NPU for these kernels"). + * Refactoring hints ("split function X; mark param Y as `dsmil_untrusted_input`"). + * Risk flags ("this path appears security-sensitive; enable sandbox profile S"). + +AI results are **never blindly trusted**: deterministic DSLLVM passes re-check constraints. + +### 8.2 Layer 7 LLM Advisor (Device 47) + +Layer 7 Device 47 hosts LLMs up to ~7B parameters with INT8 quantization. + +"L7 Advisor" roles: + +* Suggest code-level annotations: + + * Infer `dsmil_stage` from project layout / comments. + * Guess appropriate `dsmil_layer`/`device` per module (e.g., security code → L8; exec support → L9). + +* Explainability: + + * Generate human-readable rationales for policy decisions in `AI-REPORT.md`. + * Summarize complex IR into developer-friendly text for code reviews. + +DSLLVM integration: + +* Pass **`dsmil-ai-advisor-annotate`**: + + * Serializes module summary → `*.dsmilai_request.json`. + * External L7 service writes `*.dsmilai_response.json`. + * DSLLVM merges suggestions into metadata (under a "suggested" namespace; actual enforcement still via normal passes). + +### 8.3 Layer 8 Security AI Advisor + +Layer 8 provides ~188 TOPS for security AI & adversarial ML defense. + +"L8 Advisor" roles: + +* Identify risky patterns: + + * Untrusted input flows (paired with `dsmil_untrusted_input`, see §8.5). + * Potential side-channel patterns. + * Dangerous API use in security-critical layers (8–9). + +* Suggest: + + * Where to enforce `dsmil_sandbox` roles more strictly. + * Additional logging / telemetry for security-critical paths. + +DSLLVM integration: + +* **`dsmil-ai-security-scan`** pass: + + * Option 1: offline – uses pre-trained ML model embedded locally. + * Option 2: online – exports features to an L8 service. + +* Attaches: + + * `!dsmil.security_risk_score` per function. + * `!dsmil.security_hints` describing suggested mitigations. + +### 8.4 Layer 5/6 Predictive AI for Performance + +Layers 5–6 handle advanced predictive analytics and strategic simulations. + +Roles: + +* Predict per-function/runtime performance under realistic workloads: + + * Given call-frequency profiles and `*.dsmilmap` data. + * Use time-series and scenario models to predict "hot path" clusters. + +Integration: + +* **`dsmil-ai-perf-forecast`** tool: + + * Consumes: + + * History of `*.dsmilmap` + runtime metrics (latency, power). + * New build's `*.dsmilmap`. + + * Produces: + + * Forecasts: "Functions A,B,C will likely dominate latency in scenario S". + * Suggestions: move certain kernels from CPU AMX → NPU / GPU, or vice versa. + +* DSLLVM can fold this back by re-running `dsmil-device-placement` with updated targets. + +### 8.5 `dsmil_untrusted_input` & AI-Assisted IFC + +Add attribute: + +```c +__attribute__((dsmil_untrusted_input)) +``` + +* Mark function parameters / globals that ingest untrusted data. + +Combined with L8 advisor: + +* DSLLVM can: + + * Identify flows from `dsmil_untrusted_input` into dangerous sinks. + * Emit warnings or suggest `dsmil_gateway` / `dsmil_sandbox` for those paths. + * Forward high-risk flows to L8 models for deeper analysis. + +--- + +## 9. AI-Trained Cost Models & Schedulers + +Beyond "call out to the big LLMs", DSLLVM embeds **small, distilled ML models** as cost models, running locally on CPU/NPU. + +### 9.1 ML Cost Model Plugin + +Pass **`DsmilAICostModelPass`**: + +* Replaces or augments heuristic cost models for: + + * Inlining + * Loop unrolling + * Vectorization choice (AVX2 vs AMX vs NPU/GPU offload) + * Device placement (CPU/NPU/GPU) for kernels + +Implementation: + +* Trained offline using: + + * The DSMIL AI stack (L7 + L5 performance modeling). + * Historical build & runtime data from JRTC1-5450. + +* At compile-time: + + * Uses a compact ONNX model executing via OpenVINO/AMX/NPU; no network needed. + * Takes as input static features (loop depth, memory access patterns, etc.) and outputs: + + * Predicted speedup / penalty for each choice. + * Confidence scores. + +Outputs feed `dsmil-device-placement` and standard LLVM codegen decisions. + +### 9.2 Scheduler for Multi-Layer AI Deployment + +For models that can span multiple accelerators (e.g., LLMs split across AMX/iGPU/custom ASICs), DSLLVM provides a **multi-layer scheduler**: + +* Reads: + + * `*.dsmilmap` + * AI cost model outputs + * High-level objectives (e.g., "min latency subject to ≤120W power") + +* Computes: + + * Partition plan (which kernels run on which physical accelerators). + * Layer-specific deployment suggestions (e.g., route certain inference paths to Layer 7 vs Layer 9 depending on clearance). + +This is implemented as a post-link tool, but grounded in DSLLVM metadata. + +--- + +## 10. AI Integration Modes & Guardrails + +### 10.1 AI Integration Modes + +Configurable mode: + +* `--ai-mode=off` + + * No AI calls; deterministic, classic LLVM behavior. + +* `--ai-mode=local` + + * Only embedded ML cost models run (no external services). + +* `--ai-mode=advisor` + + * External L7/L8/L5 advisors used; suggestions applied only if they pass deterministic checks; all changes logged. + +* `--ai-mode=lab` + + * Permissive; DSLLVM may auto-apply AI suggestions while still satisfying layer/clearance policies. + +### 10.2 Policy Dry-Run + +Tool: `dsmil-policy-dryrun`: + +* Runs all DSMIL/AI passes in **report-only** mode: + + * Layer/clearance/ROE checks. + * Stage policy. + * Security scan. + * AI advisor hints. + * Placement & perf forecasts. + +* Emits: + + * `policy-report.json` + * Optional Markdown summary for humans. + +No IR changes, no ELF modifications. + +### 10.3 Diff-Guard for Security Posture + +Tool: `dsmil-abi-diff`: + +* Compares two builds' DSMIL posture: + + * Provenance contents. + * `*.dsmilmap` mappings. + * Sandbox profiles. + * AI risk scores and suggested mitigations. + +* Outputs: + + * "This build added a new L8 sandbox, changed Device 47 workload, and raised risk score for function X from 0.2 → 0.6." + +Useful for code review and change-approval workflows. + +### 10.4 Constant-Time / Side-Channel Annotations (`dsmil_secret`) + +Cryptographic code in Layers 8–9 requires **constant-time execution** to prevent timing side-channels. DSLLVM provides the `dsmil_secret` attribute to enforce this. + +**Attribute**: + +```c +__attribute__((dsmil_secret)) +void aes_encrypt(const uint8_t *key, const uint8_t *plaintext, uint8_t *ciphertext); + +__attribute__((dsmil_secret)) +int crypto_compare(const uint8_t *a, const uint8_t *b, size_t len); +``` + +**Semantics**: + +* Parameters/return values marked with `dsmil_secret` are **tainted** in LLVM IR with `!dsmil.secret = i1 true`. +* DSLLVM tracks data-flow of secret values through SSA graph. +* Pass **`dsmil-ct-check`** (constant-time check) enforces: + + * **No secret-dependent branches**: if/else/switch on secret data → error. + * **No secret-dependent memory access**: array indexing by secrets → error. + * **No variable-time instructions**: division, modulo with secret operands → error (unless whitelisted intrinsics like `crypto.*`). + +**AI Integration**: + +* **Layer 8 Security AI** analyzes functions marked `dsmil_secret`: + + * Identifies potential side-channel leaks (cache timing, power analysis). + * Suggests mitigations: constant-time lookup tables, masking, assembly intrinsics. + +* **Layer 5 Performance AI** balances constant-time enforcement with performance: + + * Suggests where to use AVX-512 constant-time implementations. + * Recommends hardware AES-NI vs software AES based on Device constraints. + +**Policy**: + +* Functions in Layers 8–9 with `dsmil_sandbox("crypto_worker")` **must** use `dsmil_secret` for all key material. +* Violations trigger compile-time errors in production builds (`DSMIL_PRODUCTION`). +* Lab builds (`--ai-mode=lab`) emit warnings only. + +**Metadata Output**: + +* `!dsmil.secret = i1 true` on SSA values. +* `!dsmil.ct_verified = i1 true` after `dsmil-ct-check` pass succeeds. + +**Example**: + +```c +DSMIL_LAYER(8) DSMIL_DEVICE(80) DSMIL_SANDBOX("crypto_worker") +__attribute__((dsmil_secret)) +void hmac_sha384(const uint8_t *key, const uint8_t *msg, size_t len, uint8_t *mac) { + // All operations on 'key' are constant-time enforced + // Layer 8 Security AI validates no side-channel leaks +} +``` + +### 10.5 Quantum Optimization Hints in AI I/O + +DSMIL Layer 7 Device 46 provides quantum optimization via QAOA/VQE. DSLLVM now integrates quantum hints directly into the **AI advisor I/O pipeline**. + +**Integration**: + +* When a function is marked `dsmil_quantum_candidate`, DSLLVM includes additional fields in the `*.dsmilai_request.json`: + +```json +{ + "schema": "dsmilai-request-v1.2", + "ir_summary": { + "functions": [ + { + "name": "placement_solver", + "quantum_candidate": { + "enabled": true, + "problem_type": "placement", + "variables": 128, + "constraints": 45, + "estimated_qubit_requirement": 12 + } + } + ] + } +} +``` + +* **Layer 7 LLM Advisor** or **Layer 5 Performance AI** can now: + + * Recommend whether to export QUBO (based on problem size, available quantum resources). + * Suggest hybrid classical/quantum strategies. + * Provide rationale: "Problem size (128 vars) exceeds current QPU capacity; recommend classical ILP solver on CPU." + +**Response Schema**: + +```json +{ + "schema": "dsmilai-response-v1.2", + "suggestions": [ + { + "target": "placement_solver", + "quantum_export": { + "recommended": false, + "rationale": "Problem size exceeds QPU capacity; classical ILP preferred", + "alternative": "use_highs_solver_on_cpu" + } + } + ] +} +``` + +**Pass Integration**: + +* **`dsmil-quantum-export`** pass now: + + * Reads AI advisor response. + * Only exports `*.quantum.json` if `quantum_export.recommended == true`. + * Otherwise, emits metadata suggesting classical solver. + +**Benefits**: + +* **Unified workflow**: Single AI I/O pipeline for both performance and quantum decisions. +* **Resource awareness**: L7/L5 advisors have real-time visibility into Device 46 availability and QPU queue depth. +* **Hybrid optimization**: AI can recommend splitting problems (part quantum, part classical). + +### 10.6 Compact ONNX Schema for Feature Scoring on Devices 43-58 + +DSLLVM embeds **tiny ONNX models** (~5–20 MB) for **fast feature scoring** during compilation. These models run on **Devices 43-58** (Layer 5 performance analytics accelerators, ~140 TOPS total). + +**Motivation**: + +* Full AI advisor calls (L7 LLM, L8 Security AI) have latency (~50-200ms per request). +* For **per-function cost decisions** (inlining, unrolling, vectorization), need <1ms inference. +* Solution: Use **compact ONNX models** for feature extraction + scoring, backed by
