The "upgrade to Max" subscription flow previously showed different messages depending on whether the user was in a background session. Background-session-specific strings were removed:
- "You are already on the highest Max subscription plan. For additional usage, run /login from an interactive terminal to switch to an API usage-billed account." — collapsed to a single message without the background-session qualifier.
- "Visit ... to upgrade to Max, then run /login from an interactive terminal to use your new plan." and "Visit ... to upgrade to Max. Run /login after upgrading to use your new plan." — replaced with a direct call to open the upgrade URL without a fallback text path.
Evidence
B$t function simplified (search for "You are already on the highest Max subscription plan"); background-session URL-open fallback removed (search for "to upgrade to Max, then run /login from an interactive terminal")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
