PostHogFeatureFlag

Name	Type
`id`	`number`
`name`	`string`
`key`	`string`
`bucketing_identifier`	`FeatureFlagBucketingIdentifier`
`filters`	`{ aggregation_group_type_index?: number; groups?: FeatureFlagCondition[]; multivariate?: { variants: { key: string; rollout_percentage: number; }[]; }; payloads?: Record<string, string>; holdout?: { id: number; exclusion_percentage: number; } \| null; early_exit?: boolean; }`
`deleted`	`boolean`
`active`	`boolean`
`rollout_percentage`	`number`
`ensure_experience_continuity`	`boolean`
`experiment_set`	`number[]`
`has_experiment`	`boolean`
Whether the flag is linked to an experiment. Absent when the server does not report it.
`evaluation_contexts`	`string[]`
Evaluation context tags set on the flag. The local evaluation poller keeps a flag only when this list is empty or shares at least one entry with the SDK's `evaluationContexts`. Absent when the server does not report it.
`evaluation_tags`	`string[]`
Legacy name for `evaluation_contexts`. Servers older than the field rename (PostHog, 2026-03-11) expose the same list under this key on `/flags/definitions`. Read as a fallback so local-evaluation context filtering still works against those servers.
`evaluation_runtime`	`FeatureFlagEvaluationRuntime`
Where the flag is meant to be evaluated. Absent or null on a flag that does not set a runtime, and on servers older than the field; both mean `all`, the default PostHog applies.
