chore(codegen): daily schema refresh (2026-05-23)

[timgl]

Summary

Daily refresh of src/generated/api.d.ts against the live PostHog OpenAPI schema.

• Spec diff size: ~130 lines (+129 / -11) in src/generated/api.d.ts. Entirely additive — new optional fields and enriched descriptions on already-managed schemas. openapi-filter.yaml unchanged.
• New operationIds added to filter: none. All "missing" operationIds in the live spec are either (a) auxiliary endpoints on managed families (sharing, activity, bulk_update_tags, sub-resources, sub-action mutations like experiments_recalculate_timeseries_create), or (b) belong to unmanaged resource families (logs, surveys, hog_flows, llm_analytics, warehouse, …) that we deliberately don't expose. PUT variants (*_update) on resources where we manage PATCH (*_partial_update) were also skipped — we standardize on PATCH for IaC.
• Resources touched: none. No Zod schemas or pipeline projections needed adjustment.
• Unresolved drift: none. All operationIds in openapi-filter.yaml are still present in the live spec.
• Notable schema additions (visible in the diff and now usable by downstream code):
  • ParserMode enum + parserMode on HogQL query options.
  • resultCustomizations on chart settings, usedLazyPrecompute on query response metadata, cohortLabelStartIndex on RetentionFilter, useWebAnalyticsPrecompute on WebOverviewQuery.
  • query, name/description docs on ExperimentSavedMetric / PatchedExperimentSavedMetric.
  • test_account_filters on Team / PatchedTeam, populated TeamCustomerAnalyticsConfig schema.
  • prompt_name query param on experiments_list.
  • kind discriminator fields on ActionsNode / EventsNode / ExperimentDataWarehouseNode reflowed from @constant to @enum (no semantic change — still a single-value discriminator).

Test plan

• pnpm install --frozen-lockfile
• pnpm codegen
• pnpm typecheck — clean
• pnpm test — 291 / 291 passing
