Problem

When configuring a paywall trigger for transaction_abandon, the dashboard filter UI only exposes abandoned_product_id.

The SDK already includes richer abandoned product metadata in the internal $product_* parameter set, but those fields are not copied into the explicit event parameter payload that powers the filter picker. As a result, you cannot target different paywalls based on the abandoned product duration.

Intended use case

The goal is to show a different rescue paywall depending on which subscription duration was abandoned. For example:

• If the user abandons a yearly product, show a discounted yearly paywall
• If the user abandons a monthly product, show a discounted monthly paywall
• If the user abandons a weekly product, show a discounted weekly paywall

Right now that workflow is blocked because transaction_abandon does not expose duration-related fields in the filter UI.

Solution

• Copy available abandoned product attributes into explicit abandoned_product_* event parameters
• Preserve the existing abandoned_product_id field
• Avoid emitting misleading empty duration fields for blank products used by Stripe/web checkout fallback paths
• Add test coverage for the new transaction_abandon parameter set

Notes

This addresses the App Store abandon path where a real StoreProduct is available. Stripe/web checkout abandon still only has product ID in the current model, so duration-based filtering for that path would require additional Stripe product metadata to be tracked.

Greptile Summary

This PR copies StoreProduct.attributes into the transaction_abandon audience filter params under an abandoned_product_* prefix, guarded by !product.period.isEmpty so that Stripe/web products (which return an empty period) are unaffected. The SKProductSubscriptionPeriodMock is updated from a hardcoded numberOfUnits: 1 to a configurable init to support the new test, following the same pattern already used by MockSkProduct.

Confidence Score: 5/5

This PR is safe to merge; the change is additive, well-guarded, and consistent with the existing product_* attribute pattern.

No P0 or P1 issues found. The !product.period.isEmpty guard correctly scopes the new params to App Store subscription products, the identifier key is explicitly excluded to avoid a duplicate with the separately set abandoned_product_id, and the implementation mirrors the pre-existing product_* pattern in PaywallInfo.audienceFilterParams(). Test coverage uses actual-value assertions for all new fields.

No files require special attention.
