# Timeline

**Container(s):** stellaops-timeline-web
**Slot:** 24 (timeline)  |  **Port:** 8080  |  **Consumer Group:** timeline
**Resource Tier:** light
**Network aliases:** `timeline.stella-ops.local`, `timelineindexer.stella-ops.local` (backwards compat)

## Purpose
The Timeline module provides a unified, HLC-ordered event timeline across the entire platform. It aggregates audit events from Authority, JobEngine, Policy, Evidence Locker, and Notify via HTTP polling and direct ingestion. It also serves timeline indexer query and evidence linkage endpoints (previously in separate timeline-indexer-web and timeline-indexer-worker containers, now merged).

## API Surface
- `/api/v1/audit/*` — unified audit aggregation, anomaly detection, export
- `/api/v1/timeline/*` — timeline indexer event CRUD, indexed queries, evidence linkage
- `/api/v1/timeline/hlc/*` — HLC-ordered event queries, replay, export
- `/timeline/*` — bare-prefix indexer endpoints (direct access)

## Storage
PostgreSQL schema `timeline` (via `Postgres:Timeline:ConnectionString`); Valkey for eventing

## Background Workers
- `TimelineIngestionWorker` (hosted service) — background event ingestion from NATS/Redis (transports disabled by default)

## Merge History
- Timeline Indexer (Slot 23) was merged into Timeline (Slot 24). The `timelineindexer.stella-ops.local` network alias is preserved on the timeline-web container for backwards compatibility.
