# PDF Placeholder Registry

This registry freezes the placeholder naming contract for quotation PDF templates.

| Placeholder | Type | Ownership | Notes |
| --- | --- | --- | --- |
| `customer_name` | mapped | DB mapping | customer display name |
| `customer_addr` | mapped | DB mapping | multiline address |
| `customer_tel` | mapped | DB mapping | customer phone |
| `customer_email` | mapped | DB mapping | customer email |
| `customer_att` | mapped | DB mapping | quotation attention |
| `project_name` | mapped | DB mapping | project name |
| `site_location` | mapped | DB mapping | project location |
| `quotation_date` | mapped | DB mapping | formatted date |
| `quotation_code` | mapped | DB mapping | quotation document code |
| `quotation_price` | mapped | DB mapping | formatted total amount |
| `currency` | mapped | DB mapping | currency code/label |
| `exclusion_data` | mapped | DB mapping | exclusion rows as `string[][]` |
| `app1` | mapped | DB mapping | prepared by name |
| `app1_position` | mapped | DB mapping | prepared by position |
| `app2` | mapped | DB mapping | approved by name |
| `app2_position` | mapped | DB mapping | approved by position |
| `app3` | mapped | DB mapping | authorized by name |
| `app3_position` | mapped | DB mapping | authorized by position |
| `topic` | reserved | dynamic topic engine | base runtime topic label template |
| `data_topic` | reserved | dynamic topic engine | base runtime topic rows template |
| `item_topic` | legacy reserved token | dynamic topic engine | allowed in schema token inventory, not in DB mapping rows |
| `topic_*` | generated | dynamic topic engine | runtime-only generated keys |
| `item_topic_*` | generated | dynamic topic engine | runtime-only generated keys |

## Naming Rules

- do not store `topic_*` or `item_topic_*` keys in `crm_document_template_mappings`
- keep `topic` and `data_topic` reserved for runtime schema cloning
- treat typo-like names such as `quotation_date_labe` and `quotation_code_lable` as static labels, not placeholders
- keep canonical business placeholders as `quotation_date` and `quotation_code`; container aliases like `quotation_date_data` and `quotation_code_data` are tolerated only as schema field names during the current freeze window
