# psyc
> Validate the signal, protect the evidence, route only what each destination is
> authorized to receive, and prove every external action through an immutable ledger.
Defensive cyber-threat-intelligence routing & evidence-sealing platform — a
small-worker mesh that ingests public threat feeds, classifies and seals cases,
routes them to the right destinations under TLP policy, and proves every action
through an append-only ledger. Started as a 48h hackathon (2026-05); grown into
a working platform with a fine-tuned model in operation.

## Architecture
```text
Sensors
→ Scoutline fetch + parse public feeds, emit normalized cases [built]
→ Proofline validate indicators, score confidence [planned]
→ Mapline resolve hosting country / jurisdiction [built]
→ Classifyline severity, TLP, incident type, internal class [built]
→ Sealine authority-sealed evidence encryption [built]
→ Routeline pick destinations under policy, build payloads [built]
→ Courier submit to destinations, collect receipts [built]
→ Ledgerline immutable audit of every submission + blocked route [built]
→ Publishline sanitized public intelligence after mitigation [planned]
→ Trainline lawful intel → LoRA datasets + QLoRA training [built]
→ Cockpit operator UI (FastAPI + Jinja) [built]
```
Each `-line` is a stage in a small-worker mesh; each worker does one narrow job
and passes a normalized `Case` object onward. Rules drive the deterministic
work; a fine-tuned model handles judgment (see Training). Humans approve
anything sensitive before it leaves the platform.

## Quick start
```bash
python3 -m virtualenv .venv
.venv/bin/pip install -e .
.venv/bin/psyc init # create the sqlite db
.venv/bin/psyc fetch-all # ingest URLhaus + CISA KEV + Feodo Tracker
.venv/bin/psyc demo # run one case through the whole pipeline
```
The platform runs as up to three services (each in its own terminal):
```bash
.venv/bin/psyc serve --port 8767 # operator cockpit → http://127.0.0.1:8767
.venv/bin/psyc mock-cert --port 8770 # stand-in CERT / abuse-API receiver
# optional, needs an NVIDIA GPU — puts the live model behind the Classifier bot:
docker run --gpus all --rm -p 8771:8771 --entrypoint python \
-v $(pwd)/data:/data -v $(pwd)/scripts:/scripts \
psyc-trainer /scripts/serve_model.py --adapter /data/adapters/psyc-v4/final
```
---
## Cockpit
`http://127.0.0.1:8767` — five views:
| View | Path | Shows |
|---|---|---|
| Case Queue | `/cases` | every ingested case, severity + TLP badges |
| Case detail | `/cases/{id}` | classification, observables, sealed package, routes, per-case ledger |
| Worker Mesh | `/cases/{id}/journey` | animated 7-bot replay of the case's path; the Classifier bot shows the live model's verdict |
| Ledger | `/ledger` | immutable audit feed |
| Trainline | `/train` | datasets + trained adapters with loss charts |

## Training & the live model (Trainline + QLoRA)
`psyc train-build-all` emits Alpaca-style JSONL datasets under
`data/datasets/-v.jsonl` for four defensive tasks — `ioc_extraction`,
`severity_classification`, `routing_decision`, `tlp_assignment`. QualityGate
drops TLP:RED, restricted-source, empty, and credential-leak rows.
Fine-tune Qwen3.5-4B with QLoRA in the CUDA container:
```bash
docker build -t psyc-trainer -f Dockerfile.train .
docker run --gpus all --rm --entrypoint python \
-v $(pwd)/data:/data -v $(pwd)/scripts:/scripts \
psyc-trainer /scripts/train_qlora.py \
--dataset /data/datasets/ioc_extraction-v4.jsonl \
--dataset /data/datasets/severity_classification-v4.jsonl \
--dataset /data/datasets/routing_decision-v4.jsonl \
--dataset /data/datasets/tlp_assignment-v4.jsonl \
--output /data/adapters/psyc-v4
```
Defaults target a 24 GB GPU (3090/4090): `unsloth/Qwen3.5-4B` at 4-bit, LoRA
r=16, bf16, 3 epochs. Output: `data/adapters//final/` + `training_meta.json`.
Evaluate with `scripts/eval_adapter.py`; the `/train` cockpit page shows every
dataset and adapter with its loss curve.
`scripts/serve_model.py` loads an adapter and serves `/infer` over HTTP. When
it's running, the cockpit's **Classifier bot** shows the live model's severity
verdict beside the rule's — and degrades to rules-only if the server is down.
---
## Style
All code follows [`docs/style.md`](docs/style.md) — a 12-fold guide: `Optional[X]`
/ `List[X]` from `typing`, `Field(default_factory=...)`, `Result[T, E]` for
expected failures, `class X(str, Enum)`, structlog `area.action` events,
SQLAlchemy Core (no ORM), flat hyphenated Typer commands.
---
## Scope
**Lawful, white-hat defensive operations only.** psyc routes intelligence to
victims, CERT/CSIRTs, sector ISACs, provider/registrar abuse desks, and trusted
CTI communities. It will **not** amplify stolen data, expose victims
prematurely, interact with criminal actors, distribute exploitation content, or
submit evidence beyond a destination's max TLP. Boundaries: `docs/dossier.md`
§5, §10, §16.

## Status
Working platform. Built: Scoutline (URLhaus + CISA KEV + Feodo Tracker) →
Classifyline → Mapline → Sealine → Routeline → Courier → Ledgerline → Trainline,
the FastAPI cockpit (five views incl. the animated Worker Mesh), and a
fine-tuned Qwen3.5-4B (psyc-v4) served live behind the Classifier bot.
Not yet built: Proofline (confidence scoring), Publishline (public advisories).
