Patch Changes

• #5078 f4704ac Thanks @rubychilds! - Honor filters.holdout during local feature flag evaluation. A user in an experiment holdout now receives the holdout-<id> variant instead of being bucketed into a regular variant, matching how the server evaluates the same flag. The holdout is resolved before the release conditions, so a held-out user never reaches the flag's targeting — including when those conditions would have excluded them, so isFeatureEnabled can return true where it previously returned false. Experiments with an active holdout will see variant assignment change for the held-out share of traffic on upgrade, bringing locally evaluated assignments in line with server-evaluated ones.
