Overview

Process-wide lookup of async_options keyed by Variation#digest.

Populated lazily by VariationExtension#initialize whenever a Variation is constructed with :transformer in its async_options – which happens on every view-side ‘attachment.variant(:name)` call. The redirect controller then resolves async_options by digest without scanning blob.attachments for a transformations-match.

Cold-worker behavior: if a worker receives a redirect-URL request before any view-side call has registered the variant’s digest, the lookup misses and resolution falls through to standard Rails (no leak, no spinner). Self-warms on subsequent view requests.
