Greptile Summary

Replaces the best_description Statsig experiment (single description param) with best_title (dual title + description params), wiring the new heroTitleBase through the SSR bundle, page data, and client exposure path. The default hero subtitle is updated to the new baseline copy and evaluateHeroDescriptionExperiment is fully removed with no remaining callers.

Confidence Score: 5/5

Safe to merge — migration is complete and consistent across SSR, client exposure, and both hero components.

All references to the old experiment key are removed, fallback paths are correctly handled, normalization functions are reused, and the SSR/client assignment symmetry is preserved via the Statsig bootstrap payload. No P1 or P0 findings.

No files require special attention.

Important Files Changed

Filename	Overview
src/lib/statsig/experiments/marketing-hero-server.ts	Replaces evaluateHeroDescriptionWithClient with evaluateBestTitleHeroWithClient (returns both title and description); adds heroTitleBase to MarketingHomeStatsigBundle; removes standalone evaluateHeroDescriptionExperiment export.
src/lib/statsig/experiments/marketing-hero-client.ts	Adds heroTitle to MarketingHeroStatsigBaseline; readMarketingHeroExperimentsForExposure now reads both title and description from the single best_title experiment; debug structure updated accordingly.
src/lib/statsig/constants.ts	Updates DEFAULT_HERO_SUBTITLE to new baseline copy; DEFAULT_HERO_TITLE unchanged.
src/lib/statsig/experiments/marketing-hero-ids.ts	Renames experiment key from best_description to best_title; updates JSDoc to reflect dual params (title + description).
src/lib/statsig/hero-query-overrides.ts	Extracts normalizeHeroTitle into a reusable export (was inline in readHeroTitleOverride); readHeroTitleOverride now delegates to it; doc comment updated.
src/lib/statsig/hero-statsig.server.ts	Removes re-export of the now-deleted evaluateHeroDescriptionExperiment; no other changes.
src/routes/(marketing)/(components)/hero.svelte	Passes heroTitle baseline to readMarketingHeroExperimentsForExposure for correct Pulse exposure; updates debug log key from bestDescription to bestTitle. Display continues to use SSR page.data values.
src/lib/components/homepage-variations/custom-hero.svelte	Adds clientHeroTitle reactive state; wires heroTitle into resolveHeroQueryOverrides and readMarketingHeroExperimentsForExposure, consistent with existing pattern for subtitle/layout/cta.
src/routes/(marketing)/+page.server.ts	Destructures heroTitleBase from loadMarketingHomeStatsigBundle; passes DEFAULT_HERO_TITLE as the title fallback; feeds heroTitleBase into resolveHeroQueryOverrides instead of the old hardcoded DEFAULT_HERO_TITLE.
