[BUG] Fable 5 missing from /model on Max20 — CLI stuck at "hasAvailableSubscription": false after re-login

Preflight Checklist

• [x] Searched existing issues; the "Fable missing in CLI /model" case is not filed. Related but distinct: #76093, #43118, #58101 (about weekly usage caps, same backend root cause).
• [x] Single bug report
• [x] Using the latest version of Claude Code (2.1.206)

What's Wrong?

On a Max20 subscription (billing verified in claude.ai: plan shows "Max", $220 Paid on 2026-06-09 and 2026-07-09, renews 2026-08-09), Claude Code CLI does not list Fable 5 in /model, while claude.ai (web) does offer Fable 5.

~/.claude.json shows:

"hasAvailableSubscription": false
"hasOpusPlanDefault": false

which contradicts the active Max20 plan.

claude logout → re-login was performed twice. profileFetchedAt updates each time, but the values stay false. So this is not a local cache issue — the server returns hasAvailableSubscription: false for the CLI token even though the web surface has the Fable entitlement.

The CLI binary (2.1.206) already has the real model id wired in (claude-fable-5 is present in the binary), confirming the client supports it; only the account entitlement delivered to the CLI is wrong.

This appears to share a backend root cause with #76093 / #43118 / #58101 (entitlement not re-synced after a plan change; #43118 reportedly required a backend correction of account limit values).

What Should Happen?

On Max20, the CLI should receive the same entitlement as the web app: hasAvailableSubscription should be true, and Fable 5 should appear in /model.

Steps to Reproduce

1. Be on Max20 (verified in claude.ai Billing).
2. In claude.ai chat, confirm Fable 5 is selectable.
3. In Claude Code CLI (2.1.206), open /model → Fable 5 is absent.
4. grep -E 'hasAvailableSubscription|hasOpusPlanDefault' ~/.claude.json → both false.
5. claude logout && claude (re-login), repeat step 4 → still false.

Environment

• Claude Code: 2.1.206 (native install)
• OS: macOS (Darwin 25.6.0)
• Plan: Max20
