Why: the logging aggregator wrote every event through the generic catch-all shape. The Tier-1 survey picked six high-value log sources that warrant structured parsing into logs.raw columns/fields for real querying.
How:
- Two-stage routing in `aggregator.yaml`: `app_route` peels off the six Tier-1 streams by subject / VM source tag (mutually exclusive — no double-insert); everything else falls through `app_route._unmatched` to the unchanged generic k8s/vm catch-all.
- Six parse transforms emit the full `logs.raw` shape plus structured `.fields` (Map(String,String) — no DDL change): authentik (JSON), traefik (JSON access), vault audit (JSON), nginx access+error (regex), haproxy httplog (regex), glauth (JSON).
- Companion flip: traefik-system access logs to `format: json` (both overlays) so `traefik_parse` has structured input.
- 15 new `vector test` cases (routing + field extraction) in `aggregator-tests.yaml`; all green locally (vector 0.57).
Live now: authentik + traefik (k8s). Awaiting the puppet-side vector rollout (logs.vm.* with `.file`/`.SYSLOG_IDENTIFIER` tags per the documented convention): vault-file, nginx, haproxy, glauth — transforms are present and unit-tested so they light up automatically.
Note: geoip enrichment for nginx/traefik client IPs is a separate prerequisite — no enrichment table exists in the aggregator yet; these transforms extract `client_ip` ready for it.
