Bedrock startup sometimes shows raw model id (eu.anthropic...) instead of model name

[adithya-n05]

Summary

When Claude Code starts a session on AWS Bedrock and model.display_name is not yet present in stdin, Claude HUD shows the raw Bedrock model ID (for example eu.anthropic.claude-opus-4-5-20251101-v1:0) in the statusline instead of a readable model name.

Steps to Reproduce

1. Install current main version of Claude HUD.
2. Run Claude Code with a Bedrock-backed model where startup frames may include only model.id.
3. Or reproduce directly with stdin:

echo '{"model":{"id":"eu.anthropic.claude-opus-4-5-20251101-v1:0"},"cwd":"/tmp","context_window":{"current_usage":{"input_tokens":1000},"context_window_size":200000}}' | node dist/index.js

4. Observe the rendered first line.

Expected Behavior

Model label should remain human-readable (for example Opus, Sonnet, or an intentionally normalized Bedrock model label), not the raw provider-qualified model ID.

Actual Behavior

HUD shows:

[eu.anthropic.claude-opus-4-5-20251101-v1:0 | Bedrock]

This is noisy and appears intermittently during startup depending on whether display_name is present yet.

Environment

• OS: macOS
• Node/Bun version: Node.js 22.x
• Claude Code version: 2.x

Logs or Screenshots

Observed behavior maps to current fallback logic:

• src/stdin.ts:
  • getModelName() currently returns stdin.model?.display_name ?? stdin.model?.id ?? 'Unknown'
• Bedrock detection and provider label are already correct (Bedrock), so the issue is specifically model display fallback when display_name is missing.
