+# Meal-history logger (used by the daily job)
+
+After composing the two meals (lunch + dinner) and BEFORE sending the email, the daily
+job must record them into `meal-history.json` (same skill dir) so the user can later say
+"remove <day>'s <meal> from inventory" and have precise items deducted.
+
+## Entry shape
+```json
+{
+  "date": "2026-08-27",
+  "weekday": "Thursday",
+  "meal": "lunch" | "dinner",
+  "name": "Human-readable meal name",
+  "items": [ { "name": "Name as in inventory.json", "qty": 1, "unit": "count" }, ... ]
+}
+```
+
+## Rules
+- UPSERT: if an entry with the same `date`+`meal` already exists, replace it (don't
+  duplicate on re-runs).
+- PRUNE: drop any entry whose `date` is more than 7 days before today (keep a true
+  rolling 7-day window).
+- Log ONLY substantive food items actually used in that meal — enough to decrement
+  inventory accurately. Do NOT log pure condiments (olive oil, salt, pepper, spices,
+  garlic, soy sauce, miso, honey, etc.) and do NOT log the optional "third hit" snack.
+- Item `name` values should match `inventory.json` names closely (case-insensitive match
+  on removal) so removal works: e.g. "Chicken breast", "Eggs", "Tinned tuna in veg oil",
+  "Dried red lentils", "Sweet potatoes", "Aubergine", "Red cabbage", "Green pesto",
+  "Leeks", "Orange bell pepper", "Cooked beetroot", "Microwave rice", "Cheese", etc.
+- Use units consistent with inventory.json (count / g / can / portion / pieces / jar).
+  For a half-item use 0.5 (e.g. half a sweet potato = qty 0.5 unit "count").
+- Bump the top-level file with no extra schema — keep the `entries` array only.
+- This does NOT modify inventory.json (that only happens on explicit user removal).
+
+## Example
+Composed lunch "Chicken & Pesto Roast Veg Bowl" using chicken breast (1), sweet potato
+(½), aubergine (½), red cabbage (150 g), green pesto (1 tbsp ≈ 0.1 jar) → record those
+five items under meal "lunch" for today's date/weekday.
