+# Memory Service Overview (`src/services/memory/index.js`)
+
+This document provides a high-level overview of the `src/services/memory/index.js` module, which orchestrates memory ingestion, retrieval, pruning, and persistence for the TORCH agent system.
+
+## What this module does
+
+`src/services/memory/index.js` acts as the **central controller** for the agent memory system. It coordinates:
+
+1.  **Ingestion**: Validating raw events, generating summaries, and persisting them.
+2.  **Retrieval**: Fetching relevant memories based on semantic similarity (or simple filtering) and updating usage stats.
+3.  **Pruning**: Identifying and removing stale, unpinned memories to keep the store manageable.
+4.  **Persistence**: Managing an in-memory store backed by a JSON file (`.scheduler-memory/memory-store.json`), with serialized writes to prevent corruption.
+5.  **Caching**: Providing a short-lived cache for retrieval queries to improve performance within a single run.
+
+It serves as the main API surface for agents and the scheduler to interact with long-term memory.
+
+## Key Flows
+
+### 1. Ingestion Flow (`ingestEvents`)
+
+1.  **Validate**: Checks input events against schema.
+2.  **Ingest**: Calls `ingestMemoryWindow` (in `ingestor.js`) to process events.
+3.  **Persist**: Writes new records to the in-memory store and triggers a save.
+4.  **Invalidate**: Clears the retrieval cache (`cache.clear()`) because new data might change query results.
+5.  **Telemetry**: Emits metrics and telemetry events.
+
+### 2. Retrieval Flow (`getRelevantMemories`)
+
+1.  **Check Cache**: Returns cached results if the exact query params match.
+2.  **List/Filter**: Fetches all memories or a filtered subset from the store.
+3.  **Rank**: Calls `filterAndRankMemories` (in `retriever.js`) to score relevance (e.g., using embeddings or keyword matching).
+4.  **Update Usage**: Updates `last_seen` timestamp for retrieved memories (async, fire-and-forget).
+5.  **Cache**: Stores the ranked result in the retrieval cache.
+6.  **Return**: Returns the top-k memories.
+
+### 3. Pruning Flow (`runPruneCycle`)
+
+1.  **Identify Candidates**: Calls `listPruneCandidates` (in `pruner.js`) or scans the store for unpinned memories older than `retentionMs`.
+2.  **Check Mode**:
+    *   `off`: Does nothing.
+    *   `dry-run`: Returns candidates without deleting.
+    *   `on` (default): Deletes candidates from the store.
+3.  **Persist**: Saves the updated store if changes occurred.
+4.  **Invalidate**: Clears the retrieval cache.
+
+## Public API
+
+| Function | Description |
+| :--- | :--- |
+| `ingestEvents(events, options)` | Ingests raw agent events, creates memory records, and persists them. |
+| `getRelevantMemories(params)` | Retrieves relevant memories for a query, updating usage stats. |
+| `runPruneCycle(options)` | Prunes stale, unpinned memories based on retention policy. |
+| `listMemories(filters, options)` | Lists memories with optional filtering (tags, agent_id, type) and pagination. |
+| `inspectMemory(id, options)` | Retrieves a single memory record by ID. |
+| `pinMemory(id, options)` | Pins a memory to prevent it from being pruned. |
+| `unpinMemory(id, options)` | Unpins a memory, allowing it to be pruned if it becomes stale. |
+| `markMemoryMerged(id, dest, options)` | Marks a memory as merged into another, effectively archiving it. |
+| `triggerPruneDryRun(options)` | Simulates a prune cycle to preview what would be deleted. |
+| `memoryStats(options)` | Returns aggregate statistics (counts, rates, estimated size) for observability. |
+
+## Usage Example
+
+```javascript
+import { ingestEvents, getRelevantMemories } from './src/services/memory/index.js';
+
+// 1. Ingest a new observation
+await ingestEvents([{
+  agent_id: 'test-agent',
+  content: 'The api/v1/users endpoint requires Bearer auth.',
+  timestamp: Date.now(),
+  tags: ['api', 'auth']
+}]);
+
+// 2. Retrieve relevant context later
+const memories = await getRelevantMemories({
+  agent_id: 'test-agent',
+  query: 'how to authenticate user api',
+  k: 5
+});
+
+console.log(memories);
+```
+
+## Key Invariants & Assumptions
+
+*   **Process-Local Truth**: The `memoryStore` Map is the source of truth for the running process. Multi-process coordination (locking) is handled at the scheduler level, not here.
+*   **Serialized Writes**: `saveMemoryStore` uses a promise queue (`currentSavePromise`, `pendingSavePromise`) to ensure writes to `memory-store.json` do not overlap or race, preventing data corruption.
+*   **Cache Invalidation**: Any mutation (ingest, prune, pin, merge) **must** clear the retrieval cache (`cache.clear()`) to ensure consistency.
+*   **Fire-and-Forget Usage Updates**: `updateMemoryUsage` is often called without awaiting its save operation to minimize latency on the retrieval path.
+
+## When to Change
+
+*   **Schema Updates**: If the memory record structure changes (e.g., new fields), update `ingestor.js` and `schema.js`, and ensure `index.js` passes the new fields correctly.
+*   **Persistence Strategy**: If moving from a JSON file to a real database (SQLite, Postgres), this file would need significant refactoring to replace the in-memory `Map` and `fs` calls with DB queries.
+*   **Concurrency**: If multiple agents run in parallel processes writing to the *same* memory file without a coordinator, the file-based locking/serialization here is insufficient. You would need a real DB or a dedicated memory server process.

+# Memory Update — docs-code-investigator — 2026-02-27
+
+## Key findings
+-   `src/services/memory/index.js` uses a manual promise-based queue (`performSave` / `saveMemoryStore`) to serialize file writes. This is a critical pattern to preserve if refactoring persistence.
+-   The memory store is an in-memory `Map` initialized from a JSON file at startup.
+-   Any mutation to the store *must* clear the retrieval cache (`cache.clear()`) to maintain consistency.
+
+## Patterns / reusable knowledge
+-   When documenting complex async state managers, explicitly call out the concurrency control mechanism (in this case, the save queue).
+-   JSDoc `@fileoverview` is useful for high-level module context that doesn't fit in individual function docs.
+
+## Warnings / gotchas
+-   Running multiple agent processes without a coordinator will cause race conditions on `memory-store.json` because the locking is process-local.

+
+## Goal
+Document `src/services/memory/index.js` to improve codebase maintainability and understanding. This file is a core component of the memory service, orchestrating ingestion, retrieval, and pruning.
+
+## Scope
+-   Target file: `src/services/memory/index.js` (565 LOC).
+-   Tasks:
+    -   Add JSDoc for exported functions.
+    -   Add inline comments for complex logic.
+    -   Create `docs/memory-service-index-overview.md` with high-level explanation, usage examples, and flow descriptions.
+
+## Constraints
+-   No behavioral changes.
+-   No cryptographic modifications.
+-   One file per PR (effectively, as this is the main target).
+
+## Plan
+1.  Analyze `src/services/memory/index.js` deeply.
+2.  Add JSDoc to `ingestEvents`, `getRelevantMemories`, `runPruneCycle`, `pinMemory`, `unpinMemory`, `markMemoryMerged`, `listMemories`, `inspectMemory`, `triggerPruneDryRun`, `memoryStats`.
+3.  Add inline comments to `performSave`, `saveMemoryStore`, and other internal helpers where logic is non-trivial.
+4.  Create `docs/memory-service-index-overview.md`.
+5.  Run tests (`npm test src/services/memory/index.js` and `npm run lint`) to verify no regressions/issues.

+
+Prompt: src/prompts/daily/docs-code-investigator.md
+
+## Decision: Document `src/services/memory/index.js`
+
+### Context
+`src/services/memory/index.js` is a large file (565 LOC) that serves as the main entry point for the memory service, orchestrating multiple sub-modules (`ingestor`, `retriever`, `pruner`). It has complex internal state (memory store caching, save serialization).
+
+### Rationale
+-   High complexity: It manages async persistence with a manual lock/queue mechanism (`performSave`, `saveMemoryStore`).
+-   Critical path: All memory operations pass through here.
+-   Maintenance risk: Future refactors could easily break the save serialization or cache invalidation logic if not clearly documented.
+
+### Implementation Details
+-   Will add comprehensive JSDoc for all public exports.
+-   Will add a detailed module-level comment explaining the flow and invariants.
+-   Will document the `performSave` / `saveMemoryStore` pattern specifically to prevent race conditions in future edits.

- * Key invariants:
- * - `memoryStore` is the process-local source of truth and is asynchronously persisted to `.scheduler-memory/memory-store.json`.
- * - Any mutation that affects retrieval semantics clears the in-memory cache.
- * - Save operations are serialized/coalesced (`currentSavePromise` + `pendingSavePromise`) so concurrent writes do not overlap.
