## ⚡ Key Innovations & Mathematical Formulations

### 1. Laya JEV Non-Autoregressive Routing Engine

Traditional developer tooling relies on slow, expensive LLM calls ($1,200\text{ms}+$) just to decide *which tool* to execute. The **Laya Decision Engine** replaces autoregressive classification with a deterministic, sub-millisecond ($<0.2\text{ms}$) multi-factor **Jaccard-Edit-Vector (JEV)** routing algorithm.

#### Composite JEV Scoring Function

For an incoming user query $Q$ and candidate command pattern $C$:

$$\text{JEV}(Q, C) = w_j \cdot \text{SoftJaccard}(Q, C) + w_e \cdot \text{NormalizedEditSim}(Q, C) + w_v \cdot \text{VectorScore}(Q, C)$$

where the optimal empirical weights are calibrated to:

$$w_j = 0.35, \quad w_e = 0.35, \quad w_v = 0.30 \quad \left(\sum w_k = 1.0\right)$$

#### Component Formulations:

1. **Soft Jaccard with Token Containment ($\text{SoftJaccard}$)**:
   Measures lexical set overlap while boosting queries where the full command token vocabulary is completely contained within the user input:

   $$\text{SoftJaccard}(Q, C) = \frac{|T(Q) \cap T(C)|}{|T(Q) \cup T(C)|} \cdot \left(1.0 + 0.2 \cdot \mathbb{I}(T(C) \subseteq T(Q))\right)$$

   where $T(x)$ is the normalized alphanumeric token set of string $x$, and $\mathbb{I}(\cdot)$ is the indicator function.

2. **Normalized Levenshtein Edit Similarity ($\text{NormalizedEditSim}$)**:
   Provides robust typo-tolerance against misspelled developer inputs (e.g., `"archtecture map"` $\to$ `"architecture"`, `"diagnostix doctor"` $\to$ `"doctor"`):

   $$\text{NormalizedEditSim}(Q, C) = 1.0 - \frac{\text{Levenshtein}(Q, C)}{\max(|Q|, |C|)}$$

3. ### Domain Vector Vocabulary Overlap ($\text{VectorScore}$)

Weights technical domain terms and command trigger keywords:

$$
\text{VectorScore}(Q, C) =
\frac{
\sum_{t \in T(Q) \cap T(C)}
\text{IDF}_{\text{domain}}(t)
}{
\sum_{t \in T(C)}
\text{IDF}_{\text{domain}}(t)
}
$$

### Decision Boundary & Fallback Threshold

$$
\text{Route}(Q) =
\begin{cases}
\arg\max_{C} \text{JEV}(Q,C),
& \text{if } \max_{C} \text{JEV}(Q,C) \geq \theta_{\text{route}}
\land \text{IsDeterministic}(Q)
\\[6pt]
\text{AI-FALLBACK},
& \text{if } \max_{C} \text{JEV}(Q,C) < \theta_{\text{route}}
\lor \text{IsConceptual}(Q)
\end{cases}
$$

where $\theta_{\mathrm{route}} = 0.55$.

Conceptual triggers (`"why"`, `"explain why"`, `"trade-offs"`, `"design pattern"`, `"how should we refactor"`) automatically route to the citation-grounded LLM layer.

---

### 2. Multi-Tier Refactoring Impact & Risk Classification

WIA computes the exact blast radius of changing any symbol or file by traversing the directed knowledge graph $G = (V, E)$.

#### Traversal Formulation:

- **Target Node**: $v_t \in V_{\text{symbol}} \cup V_{\text{file}}$ defined in file $f(v_t)$.
- **Direct Consumers**:
  $$\text{DirectFiles}(v_t) = \{ f(u) \mid (u, v_t) \in E \land \text{relation}(u, v_t) \in \{\text{CALLS}, \text{IMPORTS}, \text{INHERITS}\} \land f(u) \neq f(v_t) \}$$
- **Indirect/Transitive Ripple**:
  $$\text{IndirectFiles}(v_t) = \text{BFS}_{\text{depth} \le 4}(\text{DirectFiles}(v_t)) \setminus \text{DirectFiles}(v_t)$$
- **Total Affected Component Set**:
  $$\text{AffectedFiles}(v_t) = \text{DirectFiles}(v_t) \cup \text{IndirectFiles}(v_t)$$
- **Affected Test Suite**:
  $$\text{AffectedTests}(v_t) = \{ f \in \text{AffectedFiles}(v_t) \mid \text{IsTestFile}(f) \}$$

#### Evidence-Derived Risk Rating Metric:

$$\text{RiskLevel}(v_t) = \begin{cases} \mathbf{HIGH} & \text{if } |\text{AffectedFiles}(v_t)| \ge 10 \lor |\text{AffectedTests}(v_t)| \ge 5 \\ \mathbf{MEDIUM} & \text{if } 3 \le |\text{AffectedFiles}(v_t)| < 10 \\ \mathbf{LOW} & \text{if } 0 < |\text{AffectedFiles}(v_t)| < 3 \lor \left(|\text{AffectedFiles}(v_t)| = 0 \land \text{Found}(v_t)\right) \\ \mathbf{NOT\_FOUND} & \text{if } \neg\text{Found}(v_t) \end{cases}$$

> **Key Rule**: Symbol-level impact analysis evaluates the symbol's actual incoming call and reference edges. It **never** contaminates isolated symbols with whole-file container importers.

---

### 3. $O(1)$ Inverted Index & Token Relevance Engine

The WIA inverted search index maps tokens, symbols, docstring terms, and file paths into memory-mapped posting lists for instantaneous sub-millisecond retrieval.

#### Lexical Relevance Scoring:

$$\text{Score}(D, Q) = \sum_{t \in Q \cap D} \text{IDF}(t) \cdot \frac{\text{TF}(t, D) \cdot (k_1 + 1)}{\text{TF}(t, D) + k_1 \cdot \left(1 - b + b \cdot \frac{|D|}{\text{avgdl}}\right)} + \text{ExactMatchBonus}(t, D)$$

- $\text{TF}(t, D)$: Term frequency of token $t$ in document/symbol metadata $D$.
- $\text{IDF}(t) = \ln\left(1 + \frac{N - n(t) + 0.5}{n(t) + 0.5}\right)$, where $N$ is total indexed files and $n(t)$ is count of files containing $t$.
- $k_1 = 1.2$, $b = 0.75$.
- $\text{ExactMatchBonus}(t, D) = 2.5 \cdot \mathbb{I}(t = \text{SymbolName}(D))$.

---

### 4. Directional Knowledge Graph & Cycle Detection

The `WorkspaceGraph` models the entire repository as a typed directed multi-graph:

- **Node Types**: `file`, `module`, `class`, `function`, `package`.
- **Edge Types**: `DEFINES`, `CALLS`, `IMPORTS`, `INHERITS`, `DEPENDS_ON`, `TESTS`.

#### Circular Dependency Cycle Detection:
WIA executes Tarjan's Strongly Connected Components (SCC) and Depth-First Search (DFS) back-edge detection on file-level `IMPORTS` subgraphs to locate architectural violations:

$$\text{Cycle}(G) = \{ (v_1, v_2, \dots, v_k, v_1) \mid (v_i, v_{i+1}) \in E_{\text{IMPORTS}} \}$$

### Interactive Sidebar Agent View
- **View ID**: `wia-agent-view`
- Provides natural-language query routing via the embedded Laya JEV engine.
- Interactive quick-action chips for instant architecture review, dependency conflict checks, and health reports.
- Nonce-secured Content Security Policy (CSP) with complete event delegation.

### Refactoring Change Impact Inspector
- **Command**: `wia.openImpactPanel` / `wia.analyzeImpactForSymbol`
- Live inspection panel displaying:
  - Evidence-grounded risk badge (`LOW`, `MEDIUM`, `HIGH`).
  - Stat cards: **Direct Callers**, **Affected Files**, **Risk Rating**.
  - Direct callers and dependents list with clickable file navigation (`Jump to Source`).
  - Transitive downstream ripple files list.
  - One-click `Trace Flow` buttons.

### Visual Architecture & Subsystem Explorer
- **Command**: `wia.openArchPanel` / `wia.architecture`
- Interactive visual subsystem dependency map.
- Immediate circular import cycle indicators with file paths.

## ⚙️ Multi-Provider AI Configuration

Deterministic features (AST search, impact calculation, dependency conflicts, architecture diagrams, call flows) require **no API keys**.

To enable citation-grounded natural-language answers for complex conceptual questions:

```bash
# 1. OpenRouter (Recommended for Claude 3.5 Sonnet / Llama 3.3 70B)
export OPENROUTER_API_KEY="sk-or-v1-..."
wia config --set-provider openrouter --set-model anthropic/claude-3.5-sonnet

# 2. NVIDIA NIM
export NVIDIA_API_KEY="nvapi-..."
wia config --set-provider nvidia --set-model meta/llama-3.1-70b-instruct

# 3. OpenAI
export OPENAI_API_KEY="sk-..."
wia config --set-provider openai --set-model gpt-4o

# 4. Anthropic
export ANTHROPIC_API_KEY="sk-ant-..."
wia config --set-provider anthropic --set-model claude-3-5-sonnet-20241022

# 5. Google Gemini
export GEMINI_API_KEY="AIzaSy..."
wia config --set-provider gemini --set-model gemini-1.5-pro
```

In VS Code, keys can also be securely stored in OS Keychains via **`WIA: Open Settings`** without touching `.env` files.

## 🔒 Security & Privacy Guarantees

- 🛡️ **Zero Bundled Credentials**: No secrets or private keys are ever stored in source code or packaged builds.
- 🔒 **Local-First Processing**: Code indexing, graph construction, and search run entirely on your local machine.
- 🎭 **Automatic Secret Masking**: All keys and tokens are automatically masked in CLI outputs, logs, and Webviews.
- 🛡️ **Strict Content Security Policy (CSP)**: Extension webviews execute under strict nonce-secured CSP with zero inline `eval` allowances.
- 🔐 **OS Keyring Integration**: API tokens in VS Code are stored in platform credential managers via `vscode.SecretStorage`.
