# self-directed-learning

Self-directed learning framework for Hermes / Krystie — multi-strategy retrieval over UMP memory, with skill detection, decay, and triadic review.

## What this is

A continuous-learning loop for AI agents:

- **Retrieval substrate** — multi-strategy (FTS5 + vector + graph) RRF fusion with ACT-R re-ranking, served as an MCP shim so Hermes/Krystie can use it transparently through their existing UMP tool surface.
- **Memory hygiene** — nightly decay (per-kind rates, atomic writes, automatic backups), access tracking (frequency + last_accessed_at) feeding the decay and re-ranker.
- **Knowledge graph** — entity extraction + typed relations + co-occurrence edges; BFS expansion surfaces related URNs even when the direct text doesn't match.
- **Triadic review** — Claude + Codex (via Hermes OAuth / ChatGPT Pro subscription) as independent judges for claims before they're written to long-term memory.
- **Cron-driven framework** — skill gap detection, spaced repetition, foraging, reflective journaling, self-measure. All run autonomously and feed back into the retrieval substrate.

## Phases shipped

| Phase | What | Tests |
|---|---|---|
| 1 | Sidecar on `:4380` + 3-channel RRF | baseline 0.500 → 1.000 (+50pp) |
| 2 | Graph channel (typed relations + co-occurrence) | 12 unique top-5 graph-only wins |
| 3 | ACT-R re-ranker | 84% top-5 retention, 4/20 #1 changes |
| 4 | Decay script | 20/20 tests, nightly cron |
| 5 | Access tracking | 28/28 tests, feeds decay + re-ranker |
| 6 | Co-occurrence edges (in code) | (tests pending) |
| 7 | Triadic review (judge.py) | Claude + Codex wired |

## Stack

- **Language:** Node.js 18+ (sidecar, MCP shim), Python 3.11+ (decay, framework scripts)
- **Dependencies:** UMP (`@universalmemoryprotocol/core` 0.1.0), Ollama (`snowflake-arctic-embed2` 1024-dim), Qdrant (`memories_ump` collection), Express, undici, MCP SDK 1.29.
- **Repo:** `http://100.81.59.99/sami7777/self-directed-learning` (DNS3 Gitea)
- **Local path:** `/root/ump-recall/` (directory name kept for stability of running processes; only the repo was renamed)

## Run

```bash
npm start                          # sidecar on :4380
node src/ump-recall-mcp.js         # MCP shim (stdio)
python3 scripts/ump_decay.py --apply    # nightly decay
python3 scripts/judge.py --claim "..."  # Claude + Codex review
npm test                           # full test suite
```
