What
Every link into the Max upgrade flow is now built with source, medium and campaign query parameters instead of pointing at the bare upgrade URL, so each entry point is attributable.
Details
The flow builds https://claude.ai/upgrade/max?utm_source=claude_code&utm_medium=cli&utm_campaign=<surface>.
Surfaces in use: pro_trial_expired_dialog, rate_limit_options_menu, and upgrade_command from the /upgrade command.
The pro-trial-expired dialog was also switched to the same shared entry point the rate-limit options menu already used.
