From 8328e8f607d5e1065855140f6205b988aee1b78c Mon Sep 17 00:00:00 2001 From: "K. Isom" Date: Thu, 24 Sep 2026 16:08:05 -0700 Subject: [PATCH] M5a plan, task 04: chat-template tags built from pieces Task 04's session read the given test and the check.rs skeleton, both holding the tags the check refuses, and Ornith took them for its own template. It lost track of the file and made no change. The tags are now built with concat! and format! in check.rs and in the four given tests that held them, and the spec describes them in words. The rewritten tests pass against the reference, are rustfmt-clean, and still catch the case-folding mutation.
