Behaviour vs. cookbook spec

• Before editing, the model enumerated call sites via grep_search.
• Issued one edit_file per file with targeted replacements — no replace_all misfire.
• Ran git grep load_config at the end to self-verify; got empty output.
• No unrelated lines touched.

Verdict

• git grep load_config → empty. ✅
• git grep load_settings → 7 matches (definition + 6 callers — one more than the cookbook’s stated 4 because src/lib.rs has both the pub use re-export and the internal call site). ✅
• git diff --stat shows exactly the four expected files. ✅
• cargo check is expected to pass; this repo has no Cargo.lock/target cache, so the run log captures cargo check exit 0 (see tail of dscc_run.log).
