+- Warm-up guard: `SpikeConfig.DataSince` / `WarmupWindows` (default 6). No alert
+  until that much baseline exists; `spike-alerts` sets it from
+  `min(timestamp)` of `normalized_events`. Test: `TestDetectSpikesWarmupGuard`.
+- `holdout.jsonl` labelled (by Claude, review it; ambiguous 404s such as `/mcp`,
+  `/graphql`, `/api`, `/api/v2/*` were labelled `stale_reference`). Rules fixed for
+  the misses: more probe paths (`_debugbar`, `debug/pprof`, `server-info`,
+  `actuator`, `__env`, `.bash_*`, `*.key|pem|py`, `graphql/console`) and all
+  1xx/2xx/3xx are `expected_lifecycle`. 60/60, but the set is now tuned
+  against, so re-export a fresh holdout before trusting the number.
+  `IsProbePath` is shared with the blocker, so these also widen what counts as a probe.
+- Client IP gap (last 6h of nginx spans): public IPs 10.3k spans (2192 IPs),
+  `10.10.0.1` 25k (the user's firewall: traffic it NATs to ingress arrives with the firewall as source), loopback 4.1k. The loopback rows include
+  real external scanners (CameraScannerV3, MSIE8 UAs, raw-IP hosts), so ~10% of
+  spans lose the attacker IP. Ingress has `externalTrafficPolicy: Local`, no
+  `use-proxy-protocol`, and `x-real-ip` is never attached. Cause: something on the
+  node forwards to ingress from 127.0.0.1; not yet identified.
+
+- UA classes: `internal/uaclass` holds the known crawler / AI agent / monitor /
+  scan-tool list (first match wins; UA is spoofable, so a class is a positive
+  signal only). Stored as `normalized_events.ua_class` (added by
+  `EnsureNormalizedSchema` on next start; old rows are `''`), served as
+  `uaClass` on issue samples and endpoint stats. Issues UI: add-filter offers
+  `client: X` and `hide client: X`. Not yet a triage/spike feature.

+The issues view's source IP opens a dialog (`GET /api/ip/{ip}`, authed) with
+country/region/city, timezone, ASN and network. Lookups are local. Enable by
+mounting GeoLite2 files and setting `OTEL_GEOIP_CITY_DB` and/or
+`OTEL_GEOIP_ASN_DB` (the Dockerfile copies `db/*.mmdb` into the image and sets both); without them the dialog says so. Private/loopback
+addresses are labelled instead of looked up.
