+# Finish Work
+
+Wrap up the current session.
+
+## Step 1: Quality Gate
+
+`trellis-check` should have already run in Phase 3. If not, trigger it now and do not proceed until lint, type-check, tests, and spec compliance pass.
+
+## Step 2: Remind User to Commit
+
+If there are uncommitted changes:
+
+> "Please review the changes and commit when ready."
+
+Do NOT run `git commit` — the human commits after testing.
+
+## Step 3: Record Session (after commit)
+
+Archive finished tasks (judge by work status, not the `status` field):
+
+```bash
+python3 ./.trellis/scripts/task.py archive <task-name>
+```
+
+Append a session entry (auto-handles journal rotation, line count, index update):
+
+```bash
+python3 ./.trellis/scripts/add_session.py \
+  --title "Session Title" \
+  --commit "hash1,hash2" \
+  --summary "Brief summary"
+```
