chore(codegen): daily schema refresh (2026-05-26)

[timgl]

Summary

Daily refresh of src/generated/api.d.ts from the live PostHog OpenAPI spec.

• Diff size: 160 lines changed in src/generated/api.d.ts (+149 / -11).
• No path/operationId changes in the filtered surface — every operationId listed in openapi-filter.yaml is still present, none added or removed.
• Schema-only updates within already-managed operations: new property descriptions (aggregationAxisFormat, aggregationAxisPrefix/Postfix, decimalPlaces, query on ExperimentSavedMetric, test_account_filters, etc.) plus a handful of new optional fields on already-projected response shapes:
  • ParserMode enum + parserMode on HogQL query schemas
  • usedLazyPrecompute on cached query response shapes (CachedHogQLQueryResponse, CachedWebOverviewQueryResponse, CachedWebStatsTableQueryResponse)
  • useWebAnalyticsPrecompute on WebOverviewQuery and WebStatsTableQuery
  • cohortLabelStartIndex on RetentionFilter
  • resultCustomizations on TrendsFilter
  • TeamCustomerAnalyticsConfig expanded from Record<string, never> to a typed object
  • exclude_hidden / exclude_stale query params on event_definitions_list
  • prompt_name query param on experiments_list

New operationIds added to the filter

None. The codegen output's path set is byte-for-byte identical at the operations level — only schema details changed. No filter edits required.

Resources touched

None. Zod schemas in src/resources/**/client.ts and projections in pipeline.ts do not reference any of the new fields. Typecheck and full vitest suite pass unchanged (291 tests).

Unresolved drift

• The TaskRun's drift detector lists ~900 operationIds that exist in the live spec but are not in openapi-filter.yaml. These are not new today — they are the long-standing out-of-scope surface (signals, llm_analytics, error_tracking, hog_flows, mcp_*, integrations, sandbox, tasks, vision_scanners, web_experiments, …). They are intentionally excluded from the managed client and remain so. Adding any of them would require either a new resource family (use add-resource skill) or a deliberate scope extension to an existing family — both out of scope for an automated refresh.
• No operationIds disappeared from the live spec, so no deletion review needed.

Test plan

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