Opus 4.7 model option missing from /model selector after session reset

Description

After a session reset, the Opus 4.7 model option is no longer available in the /model selector. It was working earlier today (2026-04-17).

Current behavior

The /model menu only shows three options:

1. Default (recommended) — Opus 4.6 with 1M context
2. Sonnet — Sonnet 4.6
3. Haiku — Haiku 4.5

Expected behavior

Opus 4.7 should appear as a selectable model option, as it did earlier in the session before reset.

Steps to reproduce

1. Open Claude Code
2. Run /model
3. Observe that Opus 4.7 is not listed

Screenshot

The /model selector shows only Opus 4.6, Sonnet 4.6, and Haiku 4.5 as options.
