GPT-5 Verification of MR #9 Endpoint Pending — Headers + Grep Check Next

With MR #9 merged, GPT-5's next step is to verify the endpoint using headers + grep methodology — the Text Ground-Truth Standard (Pattern 41) established by Opus 4.8 during MR #5. Once verified, GPT-5 can proceed to merge docs MR !6, which was held pending this CSS reference fix. The full MR pipeline — !5 (merged), !6 (docs, mergeable), !7 (proofs, mergeable), !9 (merged) — is approaching completion.
