-#### PERF-001: N+1 Query Pattern in IndexService (CRITICAL) -**File:** `src/git_notes_memory/index.py:201` -**Status:** ✅ Fixed -**Commit:** `perf(index): fix N+1 query pattern` - -**Problem:** Loop-based queries fetching memories one at a time. -

sql += " AND m.namespace = ?" - params.append(namespace) -``` - -**Impact:** O(n) queries reduced to O(1) for vector search results. - ---- - -#### PERF-002: Model Loading Check in NoveltyChecker (CRITICAL) -**File:** `src/git_notes_memory/hooks/novelty_checker.py:85` -**Status:** ✅ Fixed -**Commit:** `perf(hooks): skip novelty check when embedding model not loaded` -

logger.debug( - "Embedding model not loaded, skipping novelty check " - "(assuming novel to avoid blocking hook execution)" - ) - return NoveltyResult(novelty_score=1.0, is_novel=True, ...) -``` - -**Impact:** Prevents hook timeout (2s limit) when model not preloaded. -

This maintains git-native semantics for both domains. + +2. **Parallel Index Pattern**: Two IndexService instances (user + project) rather than a single unified index. This keeps schemas simple and allows independent sync. + +3. **Domain as First-Class Concept**: Added `domain` field to Memory model and index schema, enabling filtering at both capture and recall. + +4. **Lazy Initialization**: User-memory infrastructure is only created when first accessed, avoiding overhead for users who don't use global memories. + +5. **Project Precedence**: When merging results, project memories appear before user memories at equal relevance, honoring local context. + +## Component Design + +### Component 1: Domain Configuration (`config.py`) + +- **Purpose**: Centralize domain-related paths and settings +- **Responsibilities**: + - Define `get_user_memories_path()` returning `~/.local/share/memory-plugin/user-memories/` + - Define `get_user_index_path()` returning `~/.local/share/memory-plugin/user/index.db` + - Provide `Domain` enum: `USER`, `PROJECT` +- **Interfaces**: Pure functions, no dependencies +- **Technology**: Python stdlib, `pathlib.Path` + +### Component 2: Domain-Aware GitOps (`git_ops.py`) + +- **Purpose**: Extended git notes operations for user domain +- **Responsibilities**: + - Initialize bare repo at user-memories path if not exists + - Support both project (existing) and user repo operations + - Manage user-memories refs: `refs/notes/mem/{namespace}` +- **Interfaces**: + - New class method `GitOps.for_domain(domain: Domain) -> GitOps` + - Factory creates appropriate instance for domain +- **Dependencies**: `config.py` for paths, `git` CLI +- **Technology**: subprocess for git commands + +### Component 3: Extended Memory Model (`models.py`) + +- **Purpose**: Add domain field to Memory dataclass +- **Responsibilities**: + -

document specifies the requirements for implementing an LLM-powered "subconsciousness" layer in the git-notes-memory system. The subconsciousness acts as an intelligent intermediary between raw memory storage and the consuming agent (Claude Code), providing automated memory capture, consolidation, intelligent forgetting, proactive surfacing, and semantic linking. + +The design is grounded in cognitive science (Dual-Process Theory, SOAR/ACT-R architectures) and validated by industry prior art (MemGPT/Letta, A-MEM, mem0). The key differentiator is the integration of adversarial robustness and confidence scoring—features largely missing from existing memory systems. + +**Key outcomes:** +1. **Implicit Capture**: Auto-detect memorable content from transcripts without explicit markers +2. **Memory Consolidation**: Merge related memories into higher-level abstractions +3. **Intelligent Forgetting**: Archive/forget stale memories based on access patterns and relevance +4. **Proactive Surfacing**: Surface relevant memories before they're explicitly requested +5. **Semantic Linking**: Create bidirectional relationships between related memories + +## Problem Statement + +### The Problem + +Current memory management in git-notes-memory is **explicit and manual**: + +- Users must explicitly capture memories with markers (`[decision]`, `[learned]`, `▶ progress`, etc.) +- Recall requires explicit search queries or context injection +- No automatic consolidation of related memories +- No intelligent forgetting of stale/redundant information +- No proactive surfacing of relevant memories +- Memory context injection is rule-based, not context-aware + +### Impact + +This results in five critical user pain points: + +| Pain Point | Impact | Frequency | +|------------|--------|-----------| +| **Capture fatigue** | Important decisions go unrecorded because users forget markers | High | +| **Information overload** | Old, redundant memories accumulate without cleanup | Medium | +| **Missed connections** | Related memories are not linked, context is lost | High | +| **Stale context** | Outdated information persists indefinitely, polluting recall | Medium | +| **Reactive only** | System waits for queries instead of proactively helping | High | + +### Current State + +The existing hooks subsystem provides foundational capabilities: +- `SessionAnalyzer` already analyzes transcripts for signals +- `_auto_capture_signals()` captures high-confidence content +- `NoveltyChecker` prevents duplicate captures +- Vector search enables semantic retrieval + +However, these are **heuristic-based** rather than LLM-powered, limiting their intelligence and adaptability. + +## Goals and Success Criteria + +### Primary Goal + +Create a cognitive memory layer that autonomously manages the memory lifecycle—capture, enrich, link, surface, consolidate, and forget—reducing user burden while improving memory quality and relevance. + +### Success Metrics + +| Metric | Target | Measurement Method | +|--------|--------|-------------------| +| Implicit capture acceptance rate | >70% | Percentage of auto-captured memories user accepts | +| Memory redundancy reduction | >30% | Duplicate/similar memories consolidated | +| Proactive surfacing usefulness | >50% | User rates surfaced memories as "useful" | +| Stale memory archival accuracy | >90% | Important memories not accidentally archived | +| Capture fatigue reduction | >60% | User satisfaction survey pre/post | + +### Non-Goals (Explicit Exclusions) + +- **Real-time LLM inference during capture**: All LLM calls are async/batched +- **Cloud dependency**: Local-only mode must function (degraded but operational) +- **Automatic memory deletion**: Forget = soft-delete/archive, not hard delete +- **Cross-repository memory sharing**: Memories scoped to single repo (future work) +- **Training/fine-tuning models**: Uses pre-trained models only + +## User Analysis + +### Primary Users + +| User Type | Needs | Context | +|-----------|-------|---------| +| **Solo developer** | Reduce capture overhead, get relevant context automatically | Daily coding sessions | +| **Team developer** | Share learnings across sessions, maintain decision history | Collaborative projects | +| **Claude Code agent** | Accurate, relevant context for coding assistance | Every interaction | + +### User Stories + +#### Implicit Capture (Dream Harvesting) + +1. As a **developer**, I want important decisions captured automatically so that I don't lose critical context when I forget to add markers. + +2. As a **team member**, I want lessons learned from debugging sessions captured so that the team benefits from individual discoveries. + +3. As a **Claude Code user**, I want session transcripts analyzed for memory-worthy content so that my interaction history becomes searchable knowledge. + +#### Memory Consolidation (Sleep Cycle) + +4. As a **developer**, I want related memories merged into abstractions so that I see patterns rather than scattered data points. + +5. As a **long-term user**, I want duplicate memories consolidated so that recall isn't cluttered with redundant information. + +#### Intelligent Forgetting (Memory Decay) + +6. As a **developer**, I want stale, superseded decisions archived so that current context isn't polluted by outdated information. + +7. As a **project maintainer**, I want completed project memories to decay gracefully so that active projects get priority. + +#### Proactive Surfacing (Intuition) + +8. As a **developer**, I want relevant memories surfaced when I open files so that I have context before I ask for it. + +9. As a **debugger**, I want past blocker resolutions surfaced when similar errors occur so that I solve problems faster. + +#### Semantic Linking (Association) + +10. As a **developer**, I want related memories linked so that I can explore connections between decisions, learnings, and patterns. + +11. As a **architect**, I want contradiction links flagged so that conflicting decisions are surfaced for resolution. + +## Functional Requirements + +### Must Have (P0) + +| ID | Requirement | Rationale
