## [0.1.0] — 2026-04-28
6+
7+
### Initial Release
8+
9+
**Core**
10+
- Relaxed DAG memory graph (Labeled Property Graph in SQLite)
11+
- 9 coding-specific node types: convention, decision, bug, spec, task, skill, preference, file, entity
12+
- 8 edge types with cycle enforcement: led_to, supersedes, caused_by, learned_in, part_of (acyclic) + relates_to, depends_on, touches (cyclic allowed)
13+
- Pure Go SQLite via `modernc.org/sqlite` — no CGO, no C compiler required
14+
- FTS5 full-text search with multi-word OR query support
15+
- SHA-256 content deduplication
16+
- Auto entity extraction (files, packages, functions, classes)
17+
- Privacy filtering (strips API keys, tokens, secrets on ingest)
18+
19+
**Interfaces**
20+
- MCP server (stdio, 12 tools) — works with any MCP-compatible agent
21+
- REST/HTTPS API (25+ endpoints, port 3456)
22+
- gRPC server (port 3457) with WatchMemories streaming
23+
- SSE streaming at `/yaad/events`
24+
- CLI (30 commands)
25+
- Web dashboard at `/yaad/ui` (D3.js force graph)
26+
27+
**Agent Integration**
28+
- `yaad setup` for 10 agents: claude-code, cursor, gemini-cli, opencode, codex-cli, cline, windsurf, goose, roo-code, aider
29+
- Auto-capture hooks: SessionStart, PostToolUse, SessionEnd
30+
- CLAUDE.md / .cursorrules / AGENTS.md bi-directional bridge
31+
32+
**Memory Intelligence**
33+
- Hot/warm/cold tier system with token budget management
34+
- Graph-aware memory decay (half-life, orphan/superseded 2× faster)
35+
- Git-aware staleness detection (propagates through graph)
36+
- Hybrid search: BM25 + vector + graph with RRF fusion
37+
- Contextual re-ranking: centrality × recency × confidence × tier
38+
- Proactive context prediction
39+
- Session compression → summary nodes
40+
- Memory feedback API (approve/edit/discard)
41+
- Version history + rollback
42+
43+
**Team & Scale**
44+
- Git chunk sync (`.yaad/chunks/*.jsonl.gz`) — append-only, no merge conflicts
45+
- Team memory namespacing
46+
- Skill/procedural memory with step sequences
47+
- JSON/Markdown/Obsidian export
48+
- Multi-project memory linking
49+
- LongMemEval-style benchmark harness
50+
51+
**Protocols**
52+
- HTTPS/TLS with auto self-signed cert generation
53+
- gRPC with protobuf service definition
54+
- WebSocket/SSE for real-time memory events

## Yaad's Unique Advantages
36+
37+
These features exist in **no other** lightweight coding memory system:
38+
39+
1. **Relaxed DAG in SQLite** — Graph power without Neo4j. Causal edges are acyclic, relational edges allow cycles.
40+
2. **Graph-propagated staleness** — File changes flag entire subgraphs, not just individual memories.
41+
3. **Impact analysis** — "What memories break if I change auth.ts?" via reverse graph traversal.
42+
4. **9 coding-specific node types** — First-class `convention`, `decision`, `bug`, `spec`, `task`, `preference`, `session`, `file`, `entity`.
43+
5. **3-stage graph search** — Seed nodes (BM25) → graph expansion (BFS) → subgraph ranking (centrality + recency).
44+
6. **Graph-aware decay** — Orphan nodes decay faster, connected nodes boost each other on access.
45+
7. **Bi-directional agent file bridge** — Sync with CLAUDE.md, .cursorrules, AGENTS.md.
46+
8. **Full version history + rollback** — Undo bad memory updates with `yaad rollback`.
47+
9. **gRPC + streaming** — Only coding memory system with gRPC. Auto-generated SDKs, real-time memory events, ~10x faster than REST.
48+
49+
## Where Yaad Is Behind (Honest)
50+
51+
| Gap | Who's Ahead | Yaad's Timeline |
52+
|---|---|---|
53+
| Proactive intent prediction | memU | Phase 3 |
54+
| Multi-modal (images) | MemOS, memU | Phase 5 |
55+
| Skill/procedural memory | MemOS, memU | Phase 5 |
56+
| LLM-based entity extraction | Mem0, Cognee | Phase 3 (regex in Phase 1) |
57+
| Auto-capture hooks | agentmemory (12 hooks) | Phase 4 |
58+
| Benchmark scores | agentmemory 95.2%, MemOS 75.8% | Phase 5 |
59+
| Community/ecosystem | Mem0 (54k⭐) | Day 0 — need to ship |
60+
61+

```
80+
81+
**Yaad's bet**: Coding agents don't need a heavy general-purpose memory system. They need a lightweight, graph-native, coding-specific memory that understands codebases, tracks relationships between decisions, and detects when things go stale. All in a single binary with zero dependencies.
