+### stack-close no longer records which model and effort ran each phase
+
+`stack-close`'s closing comment no longer carries a per-phase table of model, effort, session
+shape and compaction, nor the `size/` label beside it; the comment is the changelog line, then
+the issue closes. The operator decided the models used need not be documented (Gitea #170), so
+the record is dropped without a replacement, together with the sentences that leaned on it: `stack-mode.md` § Sessions
+and models, and two in `docs/model-and-effort-selection.md`. Which model suits which phase is
+unchanged. Dev-only apart from one `docs/` sentence; no behaviour change.
