chore(codegen): daily schema refresh (2026-05-29)

[timgl]

Summary

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

• Spec diff size: 1 file changed, 774 insertions, 15 deletions in src/generated/api.d.ts
• openapi-filter.yaml changes: none
• Resources touched: none (no Zod / pipeline edits required — additive schema-only changes)
• Typecheck: passing
• Tests: 291 / 291 passing

What changed in the spec

All deltas are additive component-schema updates — no breaking removals or renames inside the operations our filter exposes. Highlights:

• New optional warnings: DataWarehouseSyncWarning[] | null field on most query response schemas (Trends, Funnels, Retention, Lifecycle, Stickiness, HogQL, etc.) flagging stale or failed warehouse-source syncs.
• New component types: DataWarehouseSyncWarning, CalendarHeatmapFilter, ExperimentMetricOutlierHandling, ParserMode, Response7.
• AggregationPropertyType1 renamed to AggregationPropertyType (used only in experiments_create_exposure_cohort_for_experiment_create — outside our filter).
• resultCustomizations added to chart filter schemas; new cohortLabelStartIndex field; new experiment metric math fields (math, math_property, math_group_type_index, math_hogql, ignore_zeros, lower_bound_percentile, upper_bound_percentile, denominator_outlier_handling, numerator_outlier_handling).
• Discriminator-enum comment style change on kind constants (cosmetic).

New operationIds added to the filter

None. The drift report surfaced ~1,200 operationIds that exist in the live spec but are not in openapi-filter.yaml. None of them close a CRUD gap for an existing managed resource family — they are sub-resources (sharing, collaborators, activity), bulk helpers, or belong to unmanaged resource families.

A few things worth a human's eye for a future PR:

1. PUT (*_update) operations for resources we currently only manage via PATCH (*_partial_update): cohorts_update, event_definitions_update, experiment_holdouts_update, experiment_saved_metrics_update, experiments_update. PATCH is sufficient for our IaC use case so they are intentionally omitted.
2. Brand-new resource families that may be worth managing: annotations, surveys, alerts, early_access_feature, notebooks, hog_functions, hog_flows, error_tracking_*, etc. Adding any of these is significant scope (Zod schema + pipeline + diff + execute wiring + tests) and should go through the add-resource skill in a dedicated PR, not a daily refresh.

Unresolved drift

None. No operationIds previously in openapi-filter.yaml have disappeared from the live spec.
