Before, the copy was only fetched at the moment the image was handled, and only after some extra platform checks. Those extra checks no longer apply to this path.\n\nClaude Code records how each reuse turned out:\n\n- The message was sent before the JPEG copy was ready\n\n- The sign-in credential changed in the meantime\n\n- The JPEG copy was no better than the original\n\n- The prefetched copy was used\n\n- Building the image failed\n\nA second remote switch controls an extra option passed to the download step.\n\n**Why**\n\nBoth switches are off unless they are turned on from the server. The switch for reusing the earlier download read on for this site's account and for an anonymous check in a reading taken before this release.\n\n- Flag `tengu_composed_beacon`: Off by default, switched on for this account (read for one account on one subscription tier against v2.1.323; this account: on, anonymous baseline: on, compiled default: off) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Flag `tengu_unhurried_wren`: Off in both readings (read for one account on one subscription tier against v2.1.323; this account: off, anonymous baseline: off, compiled default: off) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Area: File Attachments\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
