From 48682042715f0fcfbfebe3e909db6a28cd65a909 Mon Sep 17 00:00:00 2001 From: ProfSynapse Date: Sat, 7 Feb 2026 06:24:43 -0500 Subject: [PATCH 01/19] feat: add ConversationWindowRetriever for scoped retrieval Add windowed message retrieval around matched QA pairs for the scoped search mode of Conversation Memory Search. Given a matched sequence range, computes a window of N turns before/after and fetches messages within that range. Also adds getMessagesBySequenceRange() to IMessageRepository and MessageRepository, leveraging the existing idx_messages_sequence index for efficient range queries.

/**
+ * Location: src/services/embeddings/ConversationEmbeddingWatcher.ts
+ * Purpose: Real-time indexing of completed conversation turns into the
+ * conversation embedding pipeline.
+ *
+ * Watches for assistant messages that reach state='complete' via the
+ * MessageRepository callback hook, finds the corresponding user message,
+ * builds a QA pair, and embeds it using EmbeddingService.
+ *
+ * Also embeds tool trace pairs when the assistant message contains toolCalls.
+ * For each tool call, the tool invocation (Q) and tool result (A) are paired
+ * and embedded using the same pattern as QAPairBuilder.buildQAPairs.
+ *
+ * Skip conditions:
+ * - Non-assistant messages (only assistant completions trigger embedding)
+ * - Non-complete messages (still streaming, aborted, etc.)
+ * - Branch conversations (parentConversationId is set)
+ * - Messages without text content (pure tool-call-only messages)
+ *
+ * Related Files:
+ * - src/database/repositories/MessageRepository.ts - Provides onMessageComplete hook
+ * - src/services/embeddings/EmbeddingService.ts - embedConversationTurn() for storage
+ * - src/services/embeddings/QAPairBuilder.ts - QAPair type and hashContent utility

/**
+ * Location: src/services/embeddings/ConversationEmbeddingService.ts
+ * Purpose: Domain service for conversation QA pair embedding operations.
+ *
+ * Handles embedding, searching, and managing embeddings for conversation turns.
+ * Each QA pair is chunked (Q and A independently) and stored in the
+ * conversation_embeddings vec0 table with metadata in
+ * conversation_embedding_metadata.
+ *
+ * Features:
+ * - QA pair embeddings with independent Q/A chunking
+ * - Content hash for idempotency (skip re-embedding unchanged pairs)
+ * - Semantic search with multi-signal reranking:
+ *   a. Recency boost (20% max, 14-day linear decay)
+ *   b. Session density boost (15% max, rewards clusters of related results)
+ *   c. Note reference boost (10%, rewards wiki-link matches to query terms)
+ * - Deduplication by pairId (keep best-matching chunk per pair)
+ * - Full Q and A text retrieval from messages table
+ *
+ * Relationships:
+ * - Used by EmbeddingService (facade) which delegates conversation operations here
+ * - Uses EmbeddingEngine for generating embeddings
+ * - Uses SQLiteCacheManager for vector storage
+ * - Uses ContentChunker for splitting conversation content into overlapping chunks
+ * - Uses QAPair type from QAPairBuilder
+ * - Uses extractWikiLinks from EmbeddingUtils for reference boosting

/**
+ * Location: src/services/embeddings/ConversationEmbeddingWatcher.ts
+ * Purpose: Real-time indexing of completed conversation turns into the
+ * conversation embedding pipeline.
+ *
+ * Watches for assistant messages that reach state='complete' via the
+ * MessageRepository callback hook, finds the corresponding user message,
+ * builds a QA pair, and embeds it using EmbeddingService.
+ *
+ * Also embeds tool trace pairs when the assistant message contains toolCalls.
+ * For each tool call, the tool invocation (Q) and tool result (A) are paired
+ * and embedded using the same pattern as QAPairBuilder.buildQAPairs.
+ *
+ * Skip conditions:
+ * - Non-assistant messages (only assistant completions trigger embedding)
+ * - Non-complete messages (still streaming, aborted, etc.)
+ * - Branch conversations (parentConversationId is set)
+ * - Messages without text content (pure tool-call-only messages)
+ *
+ * Related Files:
+ * - src/database/repositories/MessageRepository.ts - Provides onMessageComplete hook
+ * - src/services/embeddings/EmbeddingService.ts - embedConversationTurn() for storage
+ * - src/services/embeddings/QAPairBuilder.ts - QAPair type and hashContent utility
+ * - src/services/embeddings/EmbeddingManager.ts - Lifecycle owner (start/stop)

/**
+ * Location: src/services/embeddings/QAPairBuilder.ts
+ * Purpose: Pure function that converts conversation messages into QA pairs for embedding.
+ *
+ * Produces two types of QA pairs:
+ * 1. Conversation turns: user message (Q) paired with assistant response (A)
+ * 2. Trace pairs: tool invocation (Q) paired with tool result (A)
+ *
+ * Each QA pair has a unique pairId and contentHash for change detection.
+ * The pairs are the unit of embedding -- Q and A are chunked independently by
+ * ContentChunker, but all chunks share the same pairId. On search match,
+ * the full Q + full A are returned to the LLM.
+ *
+ * Used by:
+ * - ConversationEmbeddingWatcher: real-time embedding of completed messages
+ * - IndexingQueue: backfill embedding of existing conversations
+ * - EmbeddingService: conversation embedding pipeline
+ *
+ * Relationships:
+ * - Consumes MessageData from src/types/storage/HybridStorageTypes.ts
+ * - Output QAPairs are consumed by ContentChunker and EmbeddingService

/**
- * Location: src/services/embeddings/ContentChunker.ts
- * Purpose: Pure function that splits text into overlapping chunks for embedding.
- *
- * Chunks are indexing artifacts for the embedding pipeline. When a chunk matches
- * a search query, the full original content is returned to the LLM -- chunks
- * themselves are never displayed to users.
- *
- * Used by:
- * - QAPairBuilder: chunks Q and A independently, all chunks share a pairId
- * - EmbeddingService: will replace current 2000-char truncation with chunking
- *
- * Design decisions:
- * - 500-char chunks chosen for search precision (full pair returned regardless)
- * - 100-char overlap prevents splitting semantic units at boundaries
- * - 50-char minimum prevents tiny trailing chunks that embed poorly
- * - Trailing content below minChunkSize is merged into the previous chunk
- */
- 
-/**
- * Configuration for text chunking behavior.
- */
-export interface ChunkOptions {
-  /** Maximum number of characters per chunk. Default: 500 */
-  maxChunkSize: number;
-  /** Number of overlapping characters between consecutive chunks. Default: 100 */
-  overlap: number;
-  /** Minimum size for the final chunk. Smaller remainders merge into the previous chunk. Default: 50 */
-  minChunkSize: number;
-}

- */

-/**
- * Splits text content into overlapping chunks suitable for embedding.
- *
- * The chunking strategy uses a sliding window with configurable size and overlap.
- * The stride (step size) equals maxChunkSize - overlap. For defaults, this means
- * each chunk advances 400 characters while sharing 100 characters with its neighbor.
- *
- * Edge cases:
- * - Empty or whitespace-only content returns an empty array.
- * - Content shorter than or equal to maxChunkSize returns a single chunk.
- * - If the trailing remainder after the last full stride is shorter than minChunkSize,
- *   it is merged into the previous chunk (extending that chunk beyond maxChunkSize).
- *
- * @param content - The text to split into chunks
- * @param options - Optional partial configuration (defaults applied for missing fields)
- * @returns Array of ContentChunk objects, or empty array for empty/whitespace input

/**
- * Location: src/services/embeddings/ConversationEmbeddingService.ts
- * Purpose: Domain service for conversation QA pair embedding operations.
- *
- * Handles embedding, searching, and managing embeddings for conversation turns.
- * Each QA pair is chunked (Q and A independently) and stored in the
- * conversation_embeddings vec0 table with metadata in
- * conversation_embedding_metadata.
- *
- * Features:
- * - QA pair embeddings with independent Q/A chunking
- * - Content hash for idempotency (skip re-embedding unchanged pairs)
- * - Semantic search with multi-signal reranking:
- *   a. Recency boost (20% max, 14-day linear decay)
- *   b. Session density boost (15% max, rewards clusters of related results)
- *   c. Note reference boost (10%, rewards wiki-link matches to query terms)
- * - Deduplication by pairId (keep best-matching chunk per pair)
- * - Full Q and A text retrieval from messages table
- *
- * Relationships:
- * - Used by EmbeddingService (facade) which delegates conversation operations here
- * - Uses EmbeddingEngine for generating embeddings
- * - Uses SQLiteCacheManager for vector storage
- * - Uses ContentChunker for splitting conversation content into overlapping chunks
- * - Uses QAPair type from QAPairBuilder
- * - Uses extractWikiLinks from EmbeddingUtils for reference boosting

/**
- * Location: src/services/embeddings/ConversationEmbeddingWatcher.ts
- * Purpose: Real-time indexing of completed conversation turns into the
- * conversation embedding pipeline.
- *
- * Watches for assistant messages that reach state='complete' via the
- * MessageRepository callback hook, finds the corresponding user message,
- * builds a QA pair, and embeds it using EmbeddingService.
- *
- * Also embeds tool trace pairs when the assistant message contains toolCalls.
- * For each tool call, the tool invocation (Q) and tool result (A) are paired
- * and embedded using the same pattern as QAPairBuilder.buildQAPairs.
- *
- * Skip conditions:
- * - Non-assistant messages (only assistant completions trigger embedding)
- * - Non-complete messages (still streaming, aborted, etc.)
- * - Branch conversations (parentConversationId is set)
- * - Messages without text content (pure tool-call-only messages)
- *
- * Related Files:
- * - src/database/repositories/MessageRepository.ts - Provides onMessageComplete hook
- * - src/services/embeddings/EmbeddingService.ts - embedConversationTurn() for storage
- * - src/services/embeddings/QAPairBuilder.ts - QAPair type and hashContent utility

/**
- * Location: src/services/embeddings/QAPairBuilder.ts
- * Purpose: Pure function that converts conversation messages into QA pairs for embedding.
- *
- * Produces two types of QA pairs:
- * 1. Conversation turns: user message (Q) paired with assistant response (A)
- * 2. Trace pairs: tool invocation (Q) paired with tool result (A)
- *
- * Each QA pair has a unique pairId and contentHash for change detection.
- * The pairs are the unit of embedding -- Q and A are chunked independently by
- * ContentChunker, but all chunks share the same pairId. On search match,
- * the full Q + full A are returned to the LLM.
- *
- * Used by:
- * - ConversationEmbeddingWatcher: real-time embedding of completed messages
- * - IndexingQueue: backfill embedding of existing conversations
- * - EmbeddingService: conversation embedding pipeline
- *
- * Relationships:
- * - Consumes MessageData from src/types/storage/HybridStorageTypes.ts
- * - Output QAPairs are consumed by ContentChunker and EmbeddingService

From e910f852586f40b69eb6ef3fcca9554bca25eb9b Mon Sep 17 00:00:00 2001 From: ProfSynapse Date: Mon, 9 Feb 2026 17:00:09 -0500 Subject: [PATCH 19/19] fix: remove 45 debug console.log statements and fix TraceIndexer N+1 query Remove all console.log('[DEBUG]...') statements across 6 files per project guideline (no console.log in production). Replace per-trace embedding check (N individual SELECT queries) with a single batch query using a Set for O(1) lookup, reducing trace backfill from O(N) queries to O(1).
