Security Alerts:
- Client-side duplicate collapsing via anomaly_label + text fingerprint
- ×N count badge chip on collapsed rows; toggle to expand
- Skeleton shimmer rows replace "Loading..." text
Dashboard:
- Clickable Recent Criticals — inline LLM explanation via SSE stream
- ±5 min time window scoped to source_id for useful context
- Explanation cache keyed by entry_id (no re-fetch on re-expand)
- Default diagnose query injected on Diagnose button navigation to
prevent local models hallucinating from bare log data
- Stat card and source-health skeleton shimmer loading states
Backend:
- anomaly.py: 4-attempt retry on "database is locked" with 10s backoff
- search.py: migrate build_fts_index to get_conn() (WAL race fix);
add timeline_events to stats_summary for clickable criticals feature
- theme.css: @keyframes shimmer + .loading-shimmer utility;
prefers-reduced-motion degrades gracefully to static muted block
Second-pass cybersec classifier using DeBERTa-v3-base-mnli (already
cached — no download required). Runs after each anomaly scoring pass on
entries flagged by the anomaly scorer or with pattern matches.
Architecture:
- app/services/cybersec.py: zero-shot-classification pipeline with 5
cybersec candidate labels (auth failure, privilege escalation, network
intrusion, malware, data exfiltration). Writes ml_score/ml_label/
ml_scored_at to log_entries; inserts high-confidence hits into
detections with scorer='cybersec'.
- app/tasks/cybersec_scorer.py: async background task (same shape as
anomaly_scorer.py).
- REST: GET/POST /turnstone/api/cybersec/status|run|detections.
GET /turnstone/api/anomaly/detections now accepts scorer= filter.
Schema: ml_score, ml_label, ml_scored_at added to log_entries; scorer
column added to detections (idempotent migrations + DDL for both SQLite
and Postgres).
UI: Security Alerts view gains Source dropdown (All / Anomaly / Cybersec)
and cybersec scorer status badge. Label dropdown split into optgroups.
Deployment: TURNSTONE_CYBERSEC_MODEL/DEVICE/THRESHOLD vars added to
.env.example, docker-compose.yml, docker-standalone.sh.
Tests: 10 new tests — no model, no eligible entries, scoring, detection
creation, normal label suppression, threshold filtering, pattern-tag
filtering, idempotency, list filtering, scorer column filter.
416/416 passing.
Closes: #9
- Add app/services/anomaly.py: batch scorer using HF text-classification
pipeline; rewrites anomaly_score/anomaly_label/anomaly_scored_at on
log_entries; inserts high-confidence hits into detections table
- Add app/tasks/anomaly_scorer.py: background task (same shape as
glean_scheduler); triggered after each glean cycle when
TURNSTONE_ANOMALY_MODEL is set
- DB schema: add anomaly_score/anomaly_label/anomaly_scored_at columns to
log_entries (idempotent ALTER TABLE migration); add detections table
- Wire scorer into scheduler_loop and glean_scheduler.run_once; no-op when
model env var is empty (safe to leave unconfigured)
- REST endpoints: GET/POST /api/anomaly/status, /api/anomaly/run,
GET /api/anomaly/detections, POST /api/anomaly/detections/{id}/acknowledge
- Reuses Hybrid-BERT label map from diagnose/classifier.py; works with any
HF text-classification model
- 12 new tests; 406/406 passing
Closes: #10
