Closes item 5 on the Plan 03 cleanup triage. The option arrays
("METRICS", "COMPARATORS", KIND_OPTIONS, SEVERITY_OPTIONS, FIRE_MODES)
scattered across RouteMetricForm / JvmMetricForm / ExchangeMatchForm /
ConditionStep / ScopeStep were hand-typed string literals. They drifted
silently — P95_LATENCY_MS appeared in a dropdown without a backend
counterpart (caught at runtime in bcde6678); JvmMetric.LATEST and
Comparator.EQ existed on the backend but were missing from the UI all
along.
Fix: new `ui/src/api/alerting-enums.ts` derives every enum from
schema.d.ts and pairs each with a `Record<T, string>` label map.
TypeScript enforces exhaustiveness — adding or removing a backend
value fails the build of this file until the label map is updated.
Every consumer imports the generated `*_OPTIONS` array.
Covered (schema-derived):
- ConditionKind → CONDITION_KIND_OPTIONS
- Severity → SEVERITY_OPTIONS
- RouteMetric → ROUTE_METRIC_OPTIONS
- Comparator → COMPARATOR_OPTIONS (adds EQ that was missing)
- JvmAggregation → JVM_AGGREGATION_OPTIONS (adds LATEST that was missing)
- ExchangeMatch.fireMode → EXCHANGE_FIRE_MODE_OPTIONS
- AlertRuleTarget.kind → TARGET_KIND_OPTIONS
form-state.ts: `severity: 'CRITICAL' | 'WARNING' | 'INFO'` and
`kind: 'USER' | 'GROUP' | 'ROLE'` literal unions swapped for the
derived `Severity` / `TargetKind` aliases.
Not covered, backend types them as `String` (no `@Schema(allowableValues)`
annotation yet):
- AgentStateCondition.state
- DeploymentStateCondition.states
- LogPatternCondition.level
- ExchangeFilter.status
- JvmMetricCondition.metric
These stay hand-typed with a pointer-comment. Follow-up: add
`@Schema(allowableValues = …)` to the Java record components so the
enums land in schema.d.ts; then fold them into alerting-enums.ts.
Plus: gitnexus index-stats refresh in AGENTS.md/CLAUDE.md from the
post-deploy reindex.
Verified: ui build green, 49/49 vitest pass.
