Renames date-prefixed migrations (20260107_002, 20260408_003, 20260409_004) to plain sequential numbers (002, 003, 004) to match the convention used by other service migration directories. Adds TimelineCoreMigrationCategoryTests to verify the unified-audit migration registers under the correct category for the StartupMigrationHost transaction classifier.

Timeline
Container(s): stellaops-timeline-web
Slot: 24 (timeline) | Port: 8080 | Consumer Group: timeline
Resource Tier: light

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.localnetwork alias is preserved on the timeline-web container for backwards compatibility.
