+ # Enterprise Code Management & Git Strategy
2
+
3
+ This document outlines the software engineering principles, branch management policies, and code review criteria enforced across the **QualEdge** suite.

5

6
+
7
+ ## 1. Git Branching Model (`Trunk-Based + Feature Branches`)
8
+
9
+ To prevent production regressions and guarantee independent feature development, all development must follow isolated branch policies:
10
+
11
+ ```text
12
+ main (Protected, Production-Ready)
13
+ ├── release/v1.1.0 (Release Candidate & Staging Validation)
14
+ ├── feature/q1-int4-quantization (Feature Development)
15
+ ├── feature/q2-modernbert-router (Feature Development)
16
+ └── hotfix/aihub-timeout-retry (Emergency Hotfix)
17
+ ```
18
+
19
+ ### Branch Rules & Naming Conventions
20
+ - `main`: Production branch. Pushes directly to `main` are disabled in GitHub repository settings. All changes require an approved Pull Request (PR) passing CI.
21
+ - `feature/<feature-name>`: Scope-isolated branches for new features (e.g., `feature/sensitivity-sweep`). Merged into `main` via PR.
22
+ - `release/vX.Y.Z`: Staging candidate branches for end-to-end load testing and verification before production deployment.
23
+ - `hotfix/<issue-description>`: Critical patch branches branched directly off `main` to address production outages.
24
+
25
+ ---
26
+
27
+ ## 2. Pull Request (PR) Gating & Review Checklist
28
+
29
+ Every PR must pass automated CI checks before merging:
30
+
31
+ 1. **Automated Unit & Integration Test Pass**: `pytest tests/ -v` must execute with 0 failures.
32
+ 2. **Code Coverage Threshold**: Test coverage across `q1_compression_suite`, `q2_hybrid_router`, and `backend` must equal or exceed **80%**.
33
+ 3. **Zero Hardcoded Secrets**: Scanned via pre-commit regex check (`QAI_HUB_API_TOKEN`, `GROQ_API_KEY`, etc.).
34
+ 4. **Clean Static Analysis**: No `import *`, clean TypeScript compilation (`tsc -b`), and zero syntax/type errors.
35
+ 5. **Architectural Isolation**: Changes in `q1_compression_suite` must not break `q2_hybrid_router` or API contracts.

- ## 10 Technical Questions This Project Answers (Qualcomm & ML Systems Focus)
139
 
140
  #### Q1: Why do depthwise separable convolutions in MobileNetV2 collapse under naive quantization, and how does CLE solve this?
141
- **A:** Depthwise convolutions isolate spatial channels into independent 3x3 kernels. Without cross-channel communication, weight ranges across adjacent layers differ by up to 3 orders of magnitude. Naive tensor-wide quantization forces small-range channels into zero-bins. Cross-Layer Equalization (CLE) applies an exact mathematical weight scaling matrix \( S = \text{diag}(s_1, \dots, s_n) \) between adjacent layer pairs such that \( W_2 \cdot W_1 = (W_2 S^{-1})(S W_1) \), equalizing dynamic range across channels without altering model output.
142
 
143
  #### Q2: How does AdaRound differ from standard Post-Training Quantization (PTQ)?
144
- **A:** Standard PTQ rounds floating-point weights to the nearest integer (\(\lfloor w \rceil\)), which minimizes per-weight error but maximizes task loss curvature error on depthwise layers. AdaRound (Nagel et al., ICML 2020) formulates rounding as a continuous optimization problem per layer: \(\arg\min_V \| W x - \tilde{W}(V) x \|_F^2\) with a rectified sigmoid phase parameter \(V \in [0, 1]\). This adaptively decides whether to round up or down per weight based on task loss impact.
145
 
146
  #### Q3: Why does ReLU6 replacement surgery matter for integer scaling?
147
  **A:** ReLU6 clamps activations at upper bound 6.0. When calculated over integer quantization scales (\(S = \frac{q_{\max} - q_{\min}}{r_{\max} - r_{\min}}\)), artificial upper bounds restrict clipping range parameters and cause severe quantization noise on activation channels. Swapping `nn.ReLU6` for `nn.ReLU` before quantization unlocks full dynamic range for INT8/INT4 activation encodings.
148
 
149
  #### Q4: What is a QNN Context Binary, and why is zero CPU fallback critical for mobile battery efficiency?
150
- **A:** A QNN Context Binary (`.bin` or `.qnn`) is a hardware-compiled blob generated by Qualcomm AI Hub containing optimized Hexagon NPU microcode, weights mapped to Tight-Coupled Memory (TCM), and hardware execution graphs. If an unsupported operator falls back to Kryo CPU, execution requires memory swapping between CPU DRAM and NPU TCM, triggering context switches that increase latency by 10-40× and consume 30× more energy per query.
151
 
152
  #### Q5: How does QualEdge measure accuracy drop on INT8 and INT4 quantization?
153
  **A:** FP32 baseline (67.85% top-1) vs. INT8 W8A8 (67.80% top-1, 0.05% drop) and INT4 W4A8 (65.67% top-1, 2.18% drop) are measured across 3,925 validation images from the Imagenette dataset (`results/mobilenetv2_accuracy_measured.json`).
@@ -155,7 +180,7 @@ QualEdge Native QNN C++ Snapdragon NPU Inference Launcher
155
  #### Q6: How does the Q2 Hybrid Router prevent token collapse during degraded on-device generation?
156
  **A:** On-device language models can suffer token repetition under constrained context lengths. The Q2 router monitors real-time output entropy and 3-gram repetition ratios. If n-gram repetition exceeds 40%, the router instantly deflects generation to the cloud cascade pathway via a zero-cost failover retry.
157
 
158
- #### Q7: Why use TF-IDF + Logistic Regression for hybrid routing instead of a small LLM evaluator?
159
  **A:** A small LLM classifier (e.g. Llama-3.2-1B) adds 40-100ms of pre-routing overhead. TF-IDF + Logistic Regression computes n-gram feature vectors in **0.52 ms**, enabling instantaneous routing decisions with **93.3% accuracy** on a 120-query evaluation set.

26
+ ## 1. Problem Statement
27
+
28
+ Deploying deep learning models to mobile/edge devices requires quantization: converting float32 weights to INT8 or INT4. Naive quantization causes significant accuracy drops. Production-grade edge quantization requires:
29
+ 1. **Layer-wise quantization sensitivity analysis** — identifying which layers tolerate INT4 vs. which must remain INT8.
30
+ 2. **Hardware-specific compilation** — compiling for Qualcomm Hexagon HTP tensor formats; unoptimized models fall back to CPU (100× slower).
31
+ 3. **0 CPU fallback** — verifying op-by-op that zero operators revert to CPU DRAM context switching.
32
+ 4. **Outbox task management** — handling asynchronous quantization pipeline surgeries (BN Fold, CLE, AdaRound) reliably.
33
+
34
+ ### Why It's Hard (Engineering Significance)
35
+ - **AdaRound vs. Naive Rounding:** Naive round-to-nearest quantization minimizes per-weight error independently. AdaRound (Learned Rounding) minimizes task loss jointly — allowing weights to round up or down based on downstream output effect. Result: 2-4% higher accuracy at the same bit-width.
36
+ - **Cross-Layer Equalization (CLE):** Consecutive layers with very different weight ranges cause quantization errors to compound. CLE rescales weights between adjacent layers to equalize dynamic ranges before quantization, enabling 0 CPU fallback.
37
+ - **0 CPU Fallback Engineering:** On Hexagon HTP, any unsupported operator forces a CPU round-trip. With profiling tools, every operator is verified as HTP-executable via CLE and ReLU6 surgery.
38
+ - **41.4× Headline Speedup:** PyTorch CPU inference on Snapdragon is the worst-case baseline. The NPU achieves 0.55 ms compared to 7.12 ms on Intel OpenVINO CPU and 22.78 ms on PyTorch Eager CPU.

72
+ | Decision | Alternatives Considered | Chosen | Rationale |
73
+ |---|---|---|---|
74
+ | **Quantization Algorithm** | Naive round-to-nearest, GPTQ, AWQ | **AIMET AdaRound + CLE** | Qualcomm provides AIMET — hardware-vendor-native with Hexagon HTP support. CLE equalizes channel scales to eliminate CPU fallbacks. |
75
+ | **Request Routing** | LLM (GPT-4), RAG, Rule engine | **TF-IDF + LogReg** | **0.52 ms vs >500 ms**. Routing is a classification problem over a closed label set — an LLM adds 1000× unnecessary latency. |
76
+ | **Job Queue Architecture** | Celery + Redis, Synchronous wait | **SQLite Outbox Pattern** | Celery requires a Redis broker. SQLite outbox is durable, self-contained, transactional, and survives worker restarts. |
77
+ | **Quantization Precision** | INT8 only, FP16, INT4 mixed | **INT8 Primary, INT4 Selective** | INT8 achieves 4.04× compression with 0.05% drop; INT4 achieves 8.04× compression for storage-constrained deployments. |
78
+ | **Benchmark Verification** | Self-reported numbers, Screenshots | **Qualcomm AI Hub Job IDs** | AI Hub job ID `jgdzzyo65` is publicly verifiable on `aihub.qualcomm.com`. |

163
+ ## 9. 10 Technical Questions This Project Answers (Qualcomm & ML Systems Focus)
164
 
165
  #### Q1: Why do depthwise separable convolutions in MobileNetV2 collapse under naive quantization, and how does CLE solve this?
166
+ **A:** Depthwise convolutions isolate spatial channels into independent 3x3 kernels. Without cross-channel communication, weight ranges across adjacent layers differ by up to 3 orders of magnitude. Cross-Layer Equalization (CLE) applies an exact mathematical weight scaling matrix \( S = \text{diag}(s_1, \dots, s_n) \) between adjacent layer pairs such that \( W_2 \cdot W_1 = (W_2 S^{-1})(S W_1) \), equalizing dynamic range across channels without altering model output.
167
 
168
  #### Q2: How does AdaRound differ from standard Post-Training Quantization (PTQ)?
169
+ **A:** Standard PTQ rounds floating-point weights to the nearest integer (\(\lfloor w \rceil\)), which minimizes per-weight error independently but maximizes task loss curvature error on depthwise layers. AdaRound (Nagel et al., ICML 2020) formulates rounding as a continuous optimization problem per layer: \(\arg\min_V \| W x - \tilde{W}(V) x \|_F^2\) with a rectified sigmoid phase parameter \(V \in [0, 1]\). This adaptively decides whether to round up or down per weight based on task loss impact.
170
 
171
  #### Q3: Why does ReLU6 replacement surgery matter for integer scaling?
172
  **A:** ReLU6 clamps activations at upper bound 6.0. When calculated over integer quantization scales (\(S = \frac{q_{\max} - q_{\min}}{r_{\max} - r_{\min}}\)), artificial upper bounds restrict clipping range parameters and cause severe quantization noise on activation channels. Swapping `nn.ReLU6` for `nn.ReLU` before quantization unlocks full dynamic range for INT8/INT4 activation encodings.
173
 
174
  #### Q4: What is a QNN Context Binary, and why is zero CPU fallback critical for mobile battery efficiency?
175
+ **A:** A QNN Context Binary (`.bin`) is a hardware-compiled blob generated by Qualcomm AI Hub containing optimized Hexagon NPU microcode, weights mapped to Tight-Coupled Memory (TCM), and hardware execution graphs. If an unsupported operator falls back to Kryo CPU, execution requires memory swapping between CPU DRAM and NPU TCM, triggering context switches that increase latency by 10-40× and consume 30× more energy per query.
176
 
177
  #### Q5: How does QualEdge measure accuracy drop on INT8 and INT4 quantization?
178
  **A:** FP32 baseline (67.85% top-1) vs. INT8 W8A8 (67.80% top-1, 0.05% drop) and INT4 W4A8 (65.67% top-1, 2.18% drop) are measured across 3,925 validation images from the Imagenette dataset (`results/mobilenetv2_accuracy_measured.json`).
 
180
  #### Q6: How does the Q2 Hybrid Router prevent token collapse during degraded on-device generation?
181
  **A:** On-device language models can suffer token repetition under constrained context lengths. The Q2 router monitors real-time output entropy and 3-gram repetition ratios. If n-gram repetition exceeds 40%, the router instantly deflects generation to the cloud cascade pathway via a zero-cost failover retry.
182
 
183
+ #### Q7: Why use TF-IDF + Logistic Regression for routing instead of a small LLM evaluator?
184
  **A:** A small LLM classifier (e.g. Llama-3.2-1B) adds 40-100ms of pre-routing overhead. TF-IDF + Logistic Regression computes n-gram feature vectors in **0.52 ms**, enabling instantaneous routing decisions with **93.3% accuracy** on a 120-query evaluation set.
185
 
186
  #### Q8: How does the Transactional Outbox pattern maintain system reliability during background quantization?
