Summary

Fixes /status showing only the configured model after runtime fallback by using the latest transcript provider/model metadata as runtime truth.

Closes #23830

What changed

• /status now enables transcript-tail inspection (includeTranscriptUsage: true) so it can resolve runtime model metadata.
• readUsageFromSessionLog now captures both provider and model from transcript lines and normalizes them into a full provider/model ref.
• buildStatusMessage now applies transcript-derived runtime model even when sessionEntry.model exists, so fallback routing is reflected in status output.
• Added regression test: verifies selected model remains configured model while fallback line shows routed runtime model from transcript metadata.

Test

• pnpm -s vitest src/auto-reply/status.test.ts

Greptile Summary

Fixed /status command to display the actual routed model after runtime fallback by enabling transcript inspection and using provider/model metadata from the transcript as the source of truth.

• Enabled includeTranscriptUsage: true in commands-status.ts so transcript metadata is available
• Updated readUsageFromSessionLog to capture both provider and model from transcript lines and normalize them into a full provider/model reference
• Changed logic to apply transcript-derived runtime model even when session entry model exists, ensuring fallback routing is reflected
• Added comprehensive test coverage verifying the fallback model display
• Added security fix for GitHub Copilot token cache to validate tokens belong to the requesting account by storing and checking SHA-256 hash of the GitHub token

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The changes are well-tested with comprehensive test coverage including regression tests, follow established patterns in the codebase, and include a security improvement for the Copilot token cache. The logic changes are straightforward and align with the PR's stated goal of showing actual routed models after fallback.
• No files require special attention
