POSTHOG_WIZARD_CI_FLAG_OVERRIDES (a JSON object of flag key → value) merges over the flags PostHog returns, so CI routes deterministically — a run that tests the orchestrator arm says so instead of depending on a live flag. Published builds inline NODE_ENV and tsdown strips the entire override path from the bundle; the smoke test asserts the env var's name is physically absent from production output and present in CI output, on every build.

WIZARD_CI_FLAG_OVERRIDES, a JSON object of flag key to value, merges over whatever PostHog returns, so CI routes deterministically instead of depending on a live flag someone can edit. The override path exists only inbuild:cibundles. Published builds inline NODE_ENV and tsdown strips it entirely, and the smoke test asserts the env var's name is physically absent from production output and present in CI output, on every build. A malformed override fails the run loudly, and a valid one applies even when the flag fetch fails.
