## How this track was built
This track was generated from `DE_BERLIN` by
`0_Workflow and Pipelines CWICR/python/11-country-track-builder/add_country_track.py`.
- **Norms** (labour hours, machine hours, resource quantities) are
identical to the source track — Resource-Based Costing methodology
treats norms as country-agnostic physical first principles.
- **Prices** are derived via the cascade
`type_factors → location_factor → optional national overrides`.
Type factors come from OECD wage indexes (labour), construction
PPP (material), and ECB FX (equipment). FX snapshot date is
recorded in the per-resource columns.
- **Language** columns are translated where target language differs
from source. Existing tracks are used as parallel-text seeds.
## Data Structure
85+ columns organised into:
- Classification hierarchy (10 cols)
- Rate / work-item identifiers (11 cols)
- Resource decomposition (7 cols)
- Labour metrics (11 cols)
- Machinery & equipment (12 cols)
- Price aggregates (16 cols)
- Mass / service / regional markers (~18 cols)
See the repository-level [DATA_DICTIONARY.md](../DATA_DICTIONARY.md)
for the complete column-by-column reference.
## Qdrant collection
Vector index built from concatenated localised text fields,
encoded with OpenAI `text-embedding-3-large` (3072-dim, cosine).
```bash
