+## TICKET-007 notes (session 3)
+
+- Backend: `routers/meals.py` (from-log, unpack, PUT components — each one
+  transaction), recursive meal nutrition + cycle detection in
+  `services/nutrition.py`/`services/meals.py`; ticket-004 TODO removed —
+  summary, `GET /api/foods/{id}` (MealRead w/ `computed_nutrition_per_meal`),
+  and `GET /api/log` (nested `components` in LogFoodRead) all show real
+  derived meal nutrition. Unpack scaling verified (1.5× meal → 1.5× each
+  component); cycles (direct + transitive) → 422.
+- Frontend: Dashboard "☑ Select entries" → multi-select → MealBuilder overlay
+  (save-as-meal); LogEntry meal rows collapsible + 🔓 Unpack + "Edit
+  components" → FoodEditor meal mode (`appView='editMeal'`,
+  `mealEdit.foodId` in stores); meal kcal fix in `format.js`
+  (`caloriesForEntry` uses backend `computed_nutrition`, not
+  `calories_per_unit` which is null for meals).
+- **Process:** both implementer subagent runs this session returned truncated
+  output mid-implementation (rate limits?) — the second one wrote nothing.
+  Orchestrator implemented the meal component editor + the select-mode entry
+  point fix directly. QA agent (playwright-cli) worked well both runs and
+  caught the save-as-meal chicken-and-egg UX bug (checkboxes rendered only
+  when already selecting). Consider checking subagent reports against `git
+  status` before trusting them.
