 6. **Toxicity ranking** (`Toxicity` model): Best toxicological indicator selection with priority (NOAEL > LOAEL > LD50) and safety factors
 
 ### Caching strategy
-- ECHA results are cached in MongoDB (`toxinfo.substance_index` collection) keyed by `substance.rmlCas`
+- **ECHA results** are cached in MongoDB (`toxinfo.substance_index` collection) keyed by `substance.rmlCas`
+- **Ingredients** are cached in MongoDB (`toxinfo.ingredients` collection) keyed by `cas`, with PostgreSQL `ingredienti` table as index (stores `mongo_id` + enrichment flags `dap`, `cosing`, `tox`)
+- **Orders** are cached in MongoDB (`toxinfo.orders` collection) keyed by `uuid_ordine`
+- **Projects** are cached in MongoDB (`toxinfo.projects` collection) keyed by `uuid_progetto`
 - The orchestrator checks local cache before making external requests
+- `Ingredient.get_or_create(cas)` checks PostgreSQL -> MongoDB cache, returns cached if not older than 365 days, otherwise re-scrapes
 - Search history is logged to PostgreSQL (`logs.search_history` table)
 
+### Order / Project architecture
+- **Order** (`main_cls.py`): Raw input layer. Receives JSON with client, compiler, product type, ingredients list (CAS + percentage). Cleans CAS numbers (strips `\n`, splits by `;`). Saves to MongoDB `orders` collection. Registers client/compiler in PostgreSQL.
+- **Project** (`main_cls.py`): Processed layer. Created from an Order via `Project.from_order()`. Holds enriched `Ingredient` objects, percentages mapping (CAS -> %), and `Esposition` preset. `process_ingredients()` calls `Ingredient.get_or_create()` for each CAS. Saves to MongoDB `projects` collection.
+- An order can update an older project — they are decoupled.
+
+### PostgreSQL schema (see `data/db_schema.sql`)
+
+- **`clienti`** - Customers (`id_cliente`, `nome_cliente`)
+- **`compilatori`** - PIF compilers/assessors (`id_compilatore`, `nome_compilatore`)
+- **`ordini`** - Orders linking a client + compiler to a project (`uuid_ordine`, `uuid_progetto`, `data_ordine`, `stato_ordine`). FK to `clienti`, `compilatori`, `stati_ordini`
+- **`stati_ordini`** - Order status lookup table (`id_stato`, `nome_stato`). Values mapped to `StatoOrdine` IntEnum in `models.py`
+- **`ingredienti`** - Ingredient registry keyed by CAS. Tracks enrichment status via boolean flags (`dap`, `cosing`, `tox`) and links to MongoDB document (`mongo_id`)
+- **`inci`** - INCI name to CAS mapping. FK to `ingredienti(cas)`
+- **`progetti`** - Projects linked to an order (`mongo_id` -> `ordini.uuid_progetto`) and a product type preset (`preset_tipo_prodotto` -> `tipi_prodotti`)
+- **`ingredients_lineage`** - Many-to-many join between `progetti` and `ingredienti`, tracking which ingredients belong to which project
+- **`tipi_prodotti`** - Product type presets with exposure parameters (`preset_name`, `tipo_prodotto`, `luogo_applicazione`, exposure routes, `sup_esposta`, `freq_applicazione`, `qta_giornaliera`, `ritenzione`). Maps to the `Esposition` Pydantic model
+- **`logs.search_history`** - Search audit log (`cas_ricercato`, `target`, `esito`)

 ### Key conventions
 - Services in `services/` handle external API calls and data extraction
 - Models in `classes/models.py` use Pydantic `@model_validator` and `@classmethod` builders for construction from raw API data
+- Orchestrator classes in `classes/main_cls.py` handle Order (raw input) and Project (processed) layers
 - The `orchestrator` pattern (see `srv_echa.py`) handles: validate input -> check local cache -> fetch from external -> store locally -> return
+- `Ingredient.ingredient_builder(cas)` calls scraping functions directly (`pubchem_dap`, `cosing_entry`, `orchestrator`)
+- `Ingredient.save()` upserts to both MongoDB and PostgreSQL, `Ingredient.from_cas()` retrieves via PostgreSQL index -> MongoDB
+- `Ingredient.get_or_create(cas)` is the main entry point: checks cache freshness (365 days), scrapes if needed
 - All modules use the shared logger from `common_log.get_logger()`
 - API routes define Pydantic request/response models inline in each route file
 
+### db_utils.py functions
+- `db_connect(db_name, collection_name)` - MongoDB collection accessor
+- `postgres_connect()` - PostgreSQL connection
+- `upsert_ingrediente(cas, mongo_id, dap, cosing, tox)` - Upsert ingredient in PostgreSQL
+- `get_ingrediente_by_cas(cas)` - Get ingredient row by CAS
+- `get_all_ingredienti()` - List all ingredients from PostgreSQL
+- `upsert_cliente(nome_cliente)` - Upsert client, returns `id_cliente`
+- `upsert_compilatore(nome_compilatore)` - Upsert compiler, returns `id_compilatore`
+- `aggiorna_stato_ordine(id_ordine, nuovo_stato)` - Update order status
+- `log_ricerche(cas, target, esito)` - Log search history
+
+### Streamlit UI
+- `streamlit/ingredients_page.py` - Ingredient search by CAS + result display + inventory of ingested ingredients
+- `streamlit/exposition_page.py` - Esposition preset creation form + list of existing presets
+- Both pages call the FastAPI endpoints via `requests` (API must be running on `localhost:8000`)
+- Run with: `streamlit run streamlit/<page>.py`
+
 ### Important domain concepts
 - **CAS number**: Chemical Abstracts Service identifier (e.g., "50-00-0")
 - **INCI**: International Nomenclature of Cosmetic Ingredients
