Opus 4.7 (1M context) missing from /model picker on Bedrock

Description

When using Claude Code with AWS Bedrock, the Opus 4.7 (1M context) option does not appear in the /model picker, even when the us.anthropic.claude-opus-4-7 inference profile is enabled and accessible in the account.

Steps to Reproduce

1. Configure Claude Code to use AWS Bedrock (CLAUDE_CODE_USE_BEDROCK=1)
2. Ensure the us.anthropic.claude-opus-4-7 cross-region inference profile is enabled in your AWS account
3. Open the /model picker

Expected Behavior

"Opus 4.7 (1M context)" should appear as a selectable option in the picker, alongside the other 1M context variants (e.g. Opus 4.6 1M, Sonnet 4.6 1M).

Actual Behavior

"Opus 4.7 (1M context)" is absent from the picker. The model is usable — typing /model claude-opus-4-7[1m] works — but it never surfaces in the dropdown.

Environment

• Claude Code version: 2.1.143
• Provider: AWS Bedrock
• Platform: macOS

Notes

The Opus 4.6 (1M context) entry appears correctly for Bedrock users. The issue seems specific to the Opus 4.7 (1M context) variant — there may be a special-case condition in the Bedrock model picker path that unintentionally suppresses this entry. The firstParty/anthropicAws path does not appear to have this problem.
