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). https://claude.ai/code/session_01RWC5K8VXjBmA67Vq29sqP5

| ### 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 |
