## 🔴 High Risk Functions
### 1. `query_handler` (http_server.rs:831)
**Current State:**
```rust
pub async fn query_handler(
req: HttpRequest,
query: web::Query<HashMap<String, String>>,
state: web::Data<AppState>,
) -> HttpResponse {
// Auth validation
let (claims, token) = match validate_auth(&req, &state).await { ... }; // +1
// Capability check
if !has_capability(&claims, "memory:read") { ... } // +1
// Rate limit check
if let Err(e) = check_rate_limit(...) { ... } // +1
// Parameter extraction
let project = match query.get("project") { ... }; // +1
let question = match query.get("query") { ... }; // +1
// Semantic search
let mut semantic_results = match state.query_worker.query(...).await { ... }; // +1
// RBAC filtering
if let Some(guard) = &state.access_guard { ... } // +1
// Search method branching
match search_method {
"semantic" => { ... } // +1
"hybrid" => {
if let Some(os_client) = &state.opensearch_client { // +1
match os_client.hybrid_search(...).await { // +1
Ok(hybrid_results) => { ... }
Err(e) => { ... } // +1
}
} else { ... } // +1
}
_ => { ... } // +1
}
}
```
**Analysis:**
| Metric | Value |
|--------|-------|
| Cyclomatic Complexity | **14** |
| Test Coverage (est.) | ~20% (only RBAC helper tests) |
| **CRAP Score** | 14² × (0.8)³ + 14 = **114** |
**Anti-Patterns:**
1. ❌ Mixed responsibilities: auth, validation, search, RBAC, response formatting
2. ❌ Nested match/if blocks create cognitive maze
3. ❌ Duplicated JSON response construction (3 places)
4. ❌ No unit tests for main handler logic
**Refactored Version:**
```rust
/// Validate and extract query parameters
struct QueryParams {
project: String,
question: String,
limit: i64,
search_method: SearchMethod,
}
enum SearchMethod {
Semantic,
Hybrid,
}
impl QueryParams {
fn from_query(query: &HashMap<String, String>) -> Result<Self, HttpResponse> {
let project = query.get("project")
.ok_or_else(|| bad_request("missing project parameter"))?
.clone();
let question = query.get("query")
.ok_or_else(|| bad_request("missing query parameter"))?
.clone();
let limit = query.get("limit")
.and_then(|l| l.parse().ok())
.unwrap_or(10);
let search_method = match query.get("method").map(|s| s.as_str()) {
Some("semantic") => SearchMethod::Semantic,
_ => SearchMethod::Hybrid,
};
Ok(Self { project, question, limit, search_method })
}
}
/// Execute search based on method
async fn execute_search(
params: &QueryParams,
semantic_results: Vec<QueryResult>,
os_client: Option<&OpenSearchClient>,
token: &str,
) -> SearchResponse {
match params.search_method {
SearchMethod::Semantic => SearchResponse::semantic(semantic_results, params.limit),
SearchMethod::Hybrid => {
match os_client {
Some(client) => client.hybrid_or_fallback(semantic_results, params).await,
None => SearchResponse::semantic_only(semantic_results, params.limit),
}
}
}
}
/// Main handler - now orchestration only
pub async fn query_handler(
req: HttpRequest,
query: web::Query<HashMap<String, String>>,
state: web::Data<AppState>,
) -> HttpResponse {
let claims = validate_auth_or_return(&req, &state).await?;
require_capability(&claims, "memory:read")?;
check_rate_limit(&claims, &state, "/memory/query")?;
let params = QueryParams::from_query(&query)?;
let results = state.query_worker.query(&params.project, &params.question, Some(50)).await?;
let filtered = apply_rbac_filter(&state, &claims, results, &params.project).await;
let response = execute_search(&params, filtered, state.opensearch_client.as_ref(), &token).await;
Ok(response.into())
}
// New Complexity: 5. With tests, CRAP drops to 5.
```
**Required Tests:**
```rust
#[cfg(test)]
mod query_handler_tests {
#[test]
fn test_query_params_valid() { ... }
#[test]
fn test_query_params_missing_project() { ... }
#[test]
fn test_query_params_missing_query() { ... }
#[tokio::test]
async fn test_execute_search_semantic() { ... }
#[tokio::test]
async fn test_execute_search_hybrid_with_opensearch() { ... }
#[tokio::test]
async fn test_execute_search_hybrid_fallback() { ... }
}
```

### 2. `execute_with_wiki` (full_pipeline.rs:225)
**Current State:**
```rust
pub async fn execute_with_wiki(
&self,
query: &str,
wiki_graph: &WikiLinkGraph,
candidates: Vec<(String, String)>,
) -> Result<PipelineResult> {
let start = std::time::Instant::now();
let mut metrics = PipelineMetrics::new();
// Phase 5: Intent inference
let query_intent = MetadataExtractor::infer_query_intent(query); // +1 (method call with internal branching)
// Phase 1-4: Wiki routing
let routed = self.router.route_with_wiki_graph(...).await?; // +1
// Phase 5: Metadata boost loop
for chunk in routed.selected_chunks { // +1
let metadata = MetadataExtractor::extract(...);
if self.config.enable_metadata_boost { // +1
boost = self.booster.calculate_boost(...);
if boost > 0.0 { // +1
boosts_applied += 1;
}
}
enriched_chunks.push(...);
}
// Phase 6: Cache alignment loop
for chunk in &mut enriched_chunks { // +1
if let Some((_, slot)) = slots.iter().find(...) { // +1
chunk.cache_slot = *slot;
}
}
// ...more metric collection
}
```
**Analysis:**
| Metric | Value |
|--------|-------|
| Cyclomatic Complexity | **12** |
| Test Coverage (est.) | ~60% (integration tests) |
| **CRAP Score** | 12² × (0.4)³ + 12 = **21** |
**Anti-Patterns:**
1. ❌ God method: 150+ lines doing 6 phases
2. ❌ Timing instrumentation pollutes business logic
3. ❌ Metrics mutation scattered throughout
4. ❌ Copy-paste between `execute_with_wiki` and `execute_direct`
**Refactored Version:**
```rust
/// Phase executor trait for clean separation
trait PhaseExecutor {
async fn execute(&self, ctx: &mut PipelineContext) -> Result<()>;
}
struct IntentInferencePhase;
struct WikiRoutingPhase { router: QueryRouter }
struct MetadataBoostPhase { booster: MetadataBooster, enabled: bool }
struct CacheAlignmentPhase { aligner: KvCacheAligner }
impl PhaseExecutor for MetadataBoostPhase {
async fn execute(&self, ctx: &mut PipelineContext) -> Result<()> {
if !self.enabled { return Ok(()); }
for chunk in &mut ctx.chunks {
let metadata = MetadataExtractor::extract(&chunk.id, &chunk.text);
let boost = self.booster.calculate_boost(ctx.query_intent, &metadata);
chunk.apply_boost(boost);
ctx.metrics.record_boost(boost);
}
Ok(())
}
}
/// Main pipeline - just orchestration
pub async fn execute_with_wiki(&self, query: &str, ...) -> Result<PipelineResult> {
let mut ctx = PipelineContext::new(query);
ctx.time_phase("intent", || IntentInferencePhase.execute(&mut ctx)).await?;
ctx.time_phase("routing", || self.routing_phase.execute(&mut ctx)).await?;
ctx.time_phase("metadata", || self.metadata_phase.execute(&mut ctx)).await?;
ctx.time_phase("cache", || self.cache_phase.execute(&mut ctx)).await?;
Ok(ctx.into_result())
}
// New Complexity: 4. Each phase is independently testable.
```

## 🟡 Medium Risk Functions
### 3. `evaluate` (access_evaluator.rs:44)
**Analysis:**
| Metric | Value |
|--------|-------|
| Cyclomatic Complexity | **8** |
| Test Coverage | ~80% (17 tests) |
| **CRAP Score** | 8² × (0.2)³ + 8 = **8.5** |
**Status:** ✅ Acceptable due to high test coverage. The complexity is inherent to RBAC logic.
**Minor Improvement:** Extract role iteration into helper:
```rust
fn find_first_allowing_role(&self, claims: &Claims, resource: &ResourceMeta, verb: Verb, roles: &[Role]) -> Option<AccessDecision> {
roles.iter()
.find_map(|role| self.evaluate_role(claims, resource, verb, role))
.filter(|d| d.is_allowed())
}
```
---
### 4. `ingest_handler` (http_server.rs:423)
**Analysis:**
| Metric | Value |
|--------|-------|
| Cyclomatic Complexity | **11** |
| Test Coverage | ~10% |
| **CRAP Score** | 11² × (0.9)³ + 11 = **99** |
**Anti-Patterns:**
1. ❌ 100+ lines of sequential validation
2. ❌ No unit tests (only integration)
3. ❌ Mixed concerns: validation, RBAC, queuing, response
**Recommended Refactor:** Same pattern as `query_handler` - extract `IngestParams`, `IngestValidator`, separate RBAC check.
---
### 5. `check_all` (scope_checker.rs)
**Analysis:**
| Metric | Value |
|--------|-------|
| Cyclomatic Complexity | **6** |
| Test Coverage | ~70% |
| **CRAP Score** | 6² × (0.3)³ + 6 = **6.97** |
**Status:** ✅ Acceptable.
---
## 🟢 Low Risk Functions (Exemplary)
### `to_rbac_claims` (http_server.rs:152)
```rust
fn to_rbac_claims(jwt: &JwtClaims) -> RbacClaims {
RbacClaims::new(&jwt.sub)
.with_roles(jwt.roles.clone().unwrap_or_default().iter().map(|s| s.as_str()).collect())
.with_groups(jwt.groups.clone().unwrap_or_default().iter().map(|s| s.as_str()).collect())
.with_permissions(jwt.permissions.clone().unwrap_or_default().iter().map(|s| s.as_str()).collect())
}
```
| Metric | Value |
|--------|-------|
| Complexity | **2** |
| Coverage | 100% (3 tests) |
| **CRAP Score** | **2** ✅ |
### `query_result_to_resource_meta` (http_server.rs:160)
| Metric | Value |
|--------|-------|
| Complexity | **4** |
| Coverage | 100% (4 tests) |
| **CRAP Score** | **4** ✅ |
---
## Refactoring Priority Matrix
| Function | CRAP | LOC | Tests | Priority |
|----------|------|-----|-------|----------|
| `query_handler` | 114 | 196 | 0 | 🔴 P0 |
| `ingest_handler` | 99 | 108 | 0 | 🔴 P0 |
| `execute_with_wiki` | 21 | 150 | 6 | 🟡 P1 |
| `learn_handler` | ~50 | 170 | 0 | 🟡 P1 |
| `context_handler` | 12 | 65 | 2 | 🟢 P2 |
---
## Recommended Actions
### Immediate (P0)
1. **Extract `QueryParams` struct** from `query_handler`
2. **Add 6 unit tests** for query parameter validation
3. **Extract `IngestParams` struct** from `ingest_handler`
4. **Add 4 unit tests** for ingest validation
### Short-term (P1)
1. **Refactor `full_pipeline.rs`** using Phase Executor pattern
2. **Deduplicate** `execute_with_wiki` / `execute_direct`
3. **Add timing decorator** instead of inline instrumentation
### Long-term (P2)
1. **Generate coverage report** with `cargo-tarpaulin`
2. **Set CI gate**: CRAP > 30 fails build
3. **Extract HTTP handler helpers** into `handlers/` module
---
## Test Coverage Improvement Plan
```bash
# Install coverage tool
cargo install cargo-tarpaulin
# Generate report
cargo tarpaulin --out Html --output-dir coverage/
# Target files
cargo tarpaulin --packages mem-cli --files src/http_server.rs
```
**Target:** Achieve 80% coverage on all handlers → CRAP < 10 for all functions.
