# Evidence Case Viewer
KDE/QML app (EmbryStyle) that shows the evidence case pipeline running live,
with an agent chat well for real-time human course correction.
## Usage
```bash
# Open viewer (tail mode — watches for pipeline events)
./run.sh
# Open viewer and evaluate a question immediately
./run.sh -q "How does SV-AC-2 protect avionics bus from spoofing?"
# Connect to a specific subagent container
./run.sh --subagent-url http://localhost:8621
# Headless: run pipeline, write NDJSON events only
./run.sh --emit-only "How does X23-MUSTARD protect avionics?"
```
## Architecture
```
events.py NDJSON event emitter (pipeline wrapper)
↓ writes
/tmp/evidence-case-events.jsonl
↑ tails
bridge.py PySide6 QObject (signals + properties + chat client)
↓ binds ↕ SSE stream
qml/EvidenceCaseViewer.qml /subagent-service :8620
[Pipeline Panels] POST /chat/stream
[Agent Chat Well] GET /health
```
## Panels
- **Sentence Markup** — NVIS color-coded entity chips (RED/AMBER/YELLOW/GREEN)
- **Pipeline Gates** — gates firing in sequence with pass/fail and reasons
- **Evidence QRAs** — top QRA matches from /memory recall
- **Verdict** — final verdict badge with grade and reason
- **Agent Chat Well** — talk to the evidence case agent via /subagent-service
## Chat Well
The chat well connects to a `/subagent-service` container (default `localhost:8620`).
The agent receives full pipeline context (current question, entity markup, gate
statuses, QRA results, verdict) with each message, so it can reason about the
evidence case being built.
Example interactions:
- "Reject X23-MUSTARD — it's fabricated"
- "Why did step_2_recall pass? The QRAs don't match the question."
- "Override the verdict to not_satisfied"
- "What's the closest real control to X23-MUSTARD?"
Start a subagent before launching the viewer:
```bash
/subagent-service run.sh start --port 8620
```
