Code Review Summary

Status: No Issues Found | Recommendation: Merge

Executive Summary

The incremental change adds a dynamic promo-discount percentage to formatName, routes GPT-5.6 promo models to the OpenAI provider via OpenRouter, and formally documents pricing.discount in OpenRouterModelSchema; the schema update resolves the previously flagged discount-leak concern, and no new correctness, security, or breaking-change issues were found in the changed lines.

Previous review (commit 8c65ea8)

Status: No Issues Found | Recommendation: Merge

Executive Summary

Incremental update simplifies formatName so promoted GPT-5.6 models return only the (50% off) label (skipping $$$$/new/retires suffixes), adds a clarifying comment on the BYOK-disable flag, and updates the test to match the new early-return behavior; no correctness, security, or breaking-change issues found in the changed lines.
