Summary

This PR adds a comprehensive code analysis and optimization report documenting the current state of the claude-mem codebase, including identified issues, security vulnerabilities, performance bottlenecks, and proposed improvements.

Changes

  • Added: docs/reports/CODE-ANALYSIS-2026-03-13.md — A 951-line detailed analysis covering:
    • 8 Critical Bugs with specific file locations and fixes (e.g., OpenRouter context loss, stale session ID handling, Chroma metadata alignment)
    • 6 Security Vulnerabilities including command injection, path traversal, and insufficient validation issues
    • 11 Race Conditions in concurrency-sensitive areas (SDK resume, ChromaSync creation, file writes)
    • 9 Performance Issues including O(n²) algorithms, unbounded queries, and busy-wait patterns
    • 7 Architectural Improvements proposing service decomposition, unified agent patterns, and schema-driven validation
    • 12 Error Handling Gaps documenting missing timeout protection and silent failure modes
    • 5 Search & Retrieval Upgrades including RRF scoring and query expansion
    • 5 Exponential Accelerators for predictive pre-loading, observation graphs, and adaptive token allocation
    • 5 Self-Evolving Code Patterns for auto-tuning, schema evolution, intelligent caching, and quality scoring
    • Implementation Priority Matrix ranking 24 items from P0 (immediate) to P3 (strategic)

Notable Details

  • Each issue includes specific line numbers, code examples, and concrete fix recommendations
  • Severity levels and effort estimates provided for prioritization
  • Proposed implementations use TypeScript/Node.js patterns consistent with the existing codebase
  • Report identifies both quick wins (5-minute fixes) and strategic improvements (8-12 hour initiatives)
  • Strongest areas noted: SQLite layer, TypeScript types, hook lifecycle design
  • Weakest areas identified: Concurrency safety, Chroma sync consistency, cross-agent interop

This report serves as a roadmap for improving reliability, security, and performance across the codebase.

Deep-dive analysis of 179 source files identifying 53 issues across
security, concurrency, performance, and architecture. Includes
actionable fixes, exponential accelerators (predictive context,
observation graphs, adaptive budgets), and self-evolving code patterns
(auto-tuning telemetry, schema evolution, intelligent caching).

### BUG-003: ChromaSearch Metadata Deduplication Breaks Index Alignment
**File**: `src/services/worker/search/strategies/ChromaSearchStrategy.ts:204-217`
**Impact**: Wrong observations returned for search queries

When multiple Chroma documents map to the same SQLite ID (e.g., observation narrative + facts), only the first metadata entry is kept. Later code at line 740 accesses `rawMetadatas[i]` assuming 1:1 alignment with results — but deduplication broke that alignment.

```typescript
// FIX: Use metadata map instead of raw array indexing
const metadataMap = new Map<number, ChromaMetadata>();
for (const meta of rawMetadatas) {
if (!metadataMap.has(meta.sqlite_id)) {
metadataMap.set(meta.sqlite_id, meta);
}
}
// Then look up by ID, not by array index
```

### BUG-004: SearchOrchestrator Mutates Caller's Parameters
**File**: `src/services/worker/search/SearchOrchestrator.ts:243-255`
**Impact**: Side effects corrupt upstream state

`normalizeSearchParams()` mutates the input object via `delete normalized.obs_type`. This modifies the caller's original object, causing unpredictable behavior if the same params are reused.

```typescript
// FIX: Clone before mutation
const normalized = { ...params }; // shallow clone
delete normalized.obs_type;
return normalized;

### BUG-007: ContextBuilder Resource Leak on Init Failure
**File**: `src/services/context/ContextBuilder.ts:138-169`
**Impact**: Database handles leaked when native modules fail

If database initialization fails at line 138, the function returns early without closing `db`. The `finally` block's `db.close()` only runs in the happy path.

### SEC-002: Path Traversal in Search Context Preview
**File**: `src/services/worker/http/routes/SearchRoutes.ts:180`
**Severity**: MEDIUM

Project name from query params is used unsanitized in path construction. Input `/preview/../../../etc/passwd` could leak filesystem contents.

**Fix**: Sanitize project name to alphanumeric + dashes only.
// FIX: Clear the stale ID
if (existing?.memorySessionId) {
logger.warn(`Clearing stale memorySessionId from previous worker`);
this.dbManager.clearMemorySessionId(sessionDbId); // NEW: actually clear it
