- Restore Parameter, CorrectAnswer and _EvaluationScenario to lib/Types.ts
  (removed by cleanup while consumers remained)
- Re-export MetricColumnDefinition from the EvalRunDetails table barrel
- TooltipButtonProps was renamed EnhancedButtonProps; statusMap moved to
  @agenta/entity-ui/variant
- Synthesize full Parameter objects in UseApiContent

- useRunMetricData: type selection as the unwrapped value, not the atom
- Webhook builders: narrow WebhookFormValues union before field access
- filtersAtom: accept updater functions in the write signature
- Organization settings: drop stale react-query v4 useErrorBoundary and
  migrate setQueriesData to the v5 filters shape
- evaluations/utils: surface variantId from invocation metadata
- PreviewTableRow: add index signature required by InfiniteTableRowBase

Mirrors the vetted WP-4e-2a in-place fixes from fe-chore/move-evals-to-packages
(adapted to OSS import paths) plus new fixes for the component layer:

- restore PreviewTestCase to lib/Types; re-export MetricProcessor/MetricScope
- add "input" to EvaluationColumnKind (backend mapping emits it) and type the
  visibility-label column extension in buildPreviewColumns
- recharts v3 API drift in EvaluatorMetricsChart (TooltipContentProps, tuple
  radius, MetricStripEntry contextual typing)
- widen evaluationType to EvaluationRunKind; type query atoms as nullable
- latent runtime bugs typed as-is per WP-4e-2a convention (applyAggregatesToRaw,
  metricProcessor ReferenceErrors, dead metric-group branches) - flagged, not fixed

…ant id

- createPaginatedEntityStore: refreshAtom/actions.refresh accept an optional
  value or updater (bare set() still bumps the counter) - clears the
  'Expected 0 arguments' cluster across testset modals and other consumers
- EnvironmentStatus: variant.id optional; the component already guards it

…ing layers; oss tsc 347->105

Parallel per-area pass, behavior-preserving throughout (latent runtime bugs are
typed as-is with NOTE comments per the WP-4e-2a convention, not silently fixed):

- TraceSpanNode OSS<->entities dual-type: aligned at every crossing with
  documented boundary casts (16 errors -> 0); annotations field added to the
  OSS node (drawer stores attach it at runtime)
- SharedDrawers: broken SessionDrawerButton imports repaired, JSON-schema
  access typed, null-safety in SelectEvaluators/AnnotateDrawer, drawer
  payload/ref/label types aligned with runtime
- observability: extended-column types for custom antd props, TraceRow/
  SessionRow InfiniteTableRowBase conformance, traceTabsAtom updater support,
  ag-attributes selector typing at the producer
- playground/url-state: removed drifted local duplicates of package types,
  eagerAtom->atom where deps are sync, modal/store prop alignment
- onboarding/testsets/org: updater-widened widget UI atom, tour placement
  vocabulary fix, OnboardingLoader next/dynamic compat, org provider API
  types matched to the backend wire shape (settings/flags dicts)
- EvalRunDetails remainder: WP-4e-2a-vetted atom fixes adapted, recharts v3
  formatter/content signatures, stale import paths repointed

Flagged for triage (typed as-is): AddToTestsetDrawer trace draft discard/
update call missing molecule actions; orphaned SessionDrawerButton

…atterns; oss tsc 105->82

- InfiniteVirtualTable: canonical ExtendedColumnType exported from the barrel
  (three local extended-column copies repointed as aliases); pure read fn for
  columnHiddenKeys (write path reconciles versions); memo generic preservation;
  onRow/getRowProps/rowSelection.fixed aligned with antd 6
- antd v6 PopoverStylesType 'body' drops typed as-is (2 sites, existing pattern)
- React 19: JSX.Element -> ReactElement in RequireWorkflowKind
- AgentaNodeDTO: trace_id/span_id added (backend SpanDTO sends them)
- Org.default_workspace: list endpoint strips it - both lookups are latent
  dead code, typed as-is with comments
- FiltersPreview: operatorLabel is a display string, not the operator union

…windowing export

- DrillInUIContext: EditorProvider/SharedEditor slots typed with the real
  component prop types instead of a hand-written subset (root cause of the
  OSS provider assignment errors)
- InfiniteVirtualTable: rowSelection.fixed accepts antd FixedType; locale
  accepted (not yet forwarded - flagged); Editor barrel exports CodeLanguage
- workflow barrel exports WorkflowRevisionWindowing

Wave-2 parallel pass over the final ~105 OSS + 11 EE-only errors, behavior-
preserving throughout (latent bugs typed as-is with NOTE comments per the
WP-4e-2a convention):

- Evaluators/Evaluations: generic evaluator filtering, chart datum typing
- pages/evaluations: NewEvaluation modal props retyped to entities-package
  shapes (stale legacy Types imports dropped); antd 6 tabPlacement vocabulary
- Testcases/Testsets/Deployments: canonical ExtendedColumnType adoption,
  dataset-store variance via Pick<...,'hooks'>
- DrillInView/EditorViews: TMode narrowing via consts, Format|CodeLanguage
  state union, html format menu typing
- app-shell misc: services/state/pages sweep with backend-verified API types
- EE Billing + misc EE-only files

Latent bugs surfaced and typed as-is (chips filed where actionable):
workspace rename sends invalid org PATCH body; SessionInspector reads
status.code the backend never sends; axios.isCancel dead on created
instance; invite accept can interpolate undefined ids

Both apps are at zero tsc errors; flip ignoreBuildErrors to false so
next build guards the baseline. Verified: full oss and ee builds pass
with the gate on.

The OSS tracing module declared its own TraceSpan/TraceSpanNode plus four
TypeScript enums that mirrored the zod schemas in @agenta/entities. The two
were structurally equivalent but nominally incompatible, so every crossing
needed a cast (7 of them, added in #5464 as documented scar tissue).

- oss/src/services/tracing/types now owns only TraceSpanNode (entities node
  plus the annotations the drawer stores attach) and GenerationDashboardData;
  consumers import span types from @agenta/entities/trace directly, per the
  app-layer no-re-export rule
- 25 enum value usages become string literals; StatusCode values were already
  identical, SpanCategory differed only in the catch-all
- all 7 boundary casts removed

Fixes a live crash: AGE-3788 canonicalised the backend catch-all from
"undefined" to "unknown", but spanTypeStyles was still keyed "undefined" and
both consumers destructure the lookup, so any span typed "unknown" threw a
TypeError in the observability table and trace tree. The record is now keyed
by SpanCategory (exhaustive, so a new backend category fails the build) with a
fallback at both call sites.

Nullability now matches the payload: entities declares | null where the
backend sends null, so NodeNameCell/StatusRenderer/TimestampCell props and
ScannedExportRow were widened rather than cast.
