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. Built as a 48h hackathon project on 2026-05-13. Active development.

Architecture

Sensors
→ Scoutline      fetch, parse, dedup, signal
→ Proofline      validate indicators, score confidence
→ Mapline        resolve victim, actor, jurisdiction, CERT route
→ Classifyline   severity, TLP, incident type, internal class
→ Sealine        authority-sealed evidence encryption
→ Routeline      pick destinations, build payloads, submit
→ Ledgerline     immutable audit, receipts, outcomes
→ Publishline    sanitized public intelligence after mitigation
→ Trainline      lawful intel → LoRA-ready training data
→ Cockpit        operator UI (FastAPI + Jinja)

Each -line is a stage in a small-worker mesh; each worker performs one narrow job and passes a normalized Case object to the next stage. Heavy models are reserved for judgment-heavy tasks. Humans approve everything sensitive before it leaves the platform.

Full architecture: docs/dossier.md — consolidated read of the original individual records (still in docs/archive/).

Quick start

python3 -m virtualenv .venv
.venv/bin/pip install -e .

.venv/bin/psyc init                       # create the sqlite db
.venv/bin/psyc fetch-urlhaus --limit 50   # ingest a URLhaus pass
.venv/bin/psyc serve --port 8767          # cockpit at http://127.0.0.1:8767
.venv/bin/psyc status                     # count of ingested cases

Style

All code follows docs/style.md: Optional[X] / List[X] from typing, Field(default_factory=...) for Pydantic mutables, Result[T, E] types for expected failures (raise reserved for true exceptions), class X(str, Enum) for closed string sets, structlog with area.action event names, SQLAlchemy Core (no ORM), flat Typer commands with hyphenated names. Ruff config in pyproject.toml enforces the bits a linter can check; UP006/UP007/UP035 are disabled so the typing-import rules stand.

---

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
• submit evidence that exceeds a destination's max TLP

The boundaries are defined in docs/dossier.md §5 Destination Minimization, §10 TLP Enforcement, and §16 Public Reporting Rules. The Ledger records every external submission and destructive action; sensitive evidence is encrypted to authorized recipients via Sealine before any routing decision.

Training (Trainline + QLoRA)

psyc train-build-all emits Alpaca-style JSONL datasets under data/datasets/<task>-v<n>.jsonl for four defensive tasks: ioc_extraction, severity_classification, routing_decision, tlp_assignment. QualityGate drops TLP:RED, restricted sources, empty/oversize, and credential-leak rows per the dossier's training-data policy.

To fine-tune Qwen3.5-4B with QLoRA in an NVIDIA Docker container:

# 1. build datasets (one-off; re-run after ingestion changes)
.venv/bin/psyc train-build-all

# 2. build the training image (CUDA 12.4 + unsloth + Qwen3.5)
docker build -t psyc-trainer -f Dockerfile.train .

# 3. fine-tune (mount host data/ so adapters land there)
docker run --gpus all --rm \
    -v $(pwd)/data:/data \
    psyc-trainer \
    --dataset /data/datasets/ioc_extraction-v1.jsonl \
    --dataset /data/datasets/severity_classification-v1.jsonl \
    --dataset /data/datasets/routing_decision-v1.jsonl \
    --dataset /data/datasets/tlp_assignment-v1.jsonl \
    --output /data/adapters/psyc-v1

Defaults target a 24 GB consumer GPU (3090/4090): Qwen3.5-4B-Instruct at 4-bit, LoRA r=16/alpha=16, bf16, 3 epochs, effective batch size 8. For A100-40/80 bump --base-model unsloth/Qwen3.5-9B-Instruct-bnb-4bit and raise --batch-size + --max-seq-length.

Output: data/adapters/psyc-v1/final/ (adapter weights) + training_meta.json (base model, hyperparameters, dataset list).

Status

Day 2 of a 48h build. Shipped: Scoutline (URLhaus) → Classifyline → Mapline (GeoResolver via ip-api.com) → Sealine (PyNaCl sealed boxes) → Routeline → Courier → mock CERT → Ledgerline. Cockpit has cases / case detail / ledger pages and a design-token CSS layer. Trainline emits LoRA-ready JSONL; Dockerfile.train builds an unsloth + Qwen3.5 QLoRA training container.
