Patch Changes

• Fable 5.1 is selectable in App Settings.

  claude-fable-5-1 is in Claude Code's model catalog (display name "Fable 5.1", June 2026 knowledge cutoff), but the model picker only went up to Fable 5, so pinning it meant hand-editing a case's .claude/settings.local.json. It now appears as a card under App Settings -> Models -> New Claude sessions, and as an option in Task routing (Default for tasks, plus the Explore / Implement / Test / Review overrides).

  It is offered exactly the way Fable 5 already is: the "1M capable" badge, the 1M context window switch stays live for it, and base + switch compose into claude-fable-5-1[1m]. Both strings are accepted by the CLI.

  Deliberately not claimed: that a 1M window is what sets Fable 5.1 apart. The CLI's model catalog marks both fable entries as natively 1M with the same window, so an always-on window for 5.1 next to a switchable one for 5 would encode a difference the models do not have.

  Thanks

  • @shenlvkang-collab for #370, which surfaced that Fable 5.1 was missing from the picker.
