# The Biergarten Data Pipeline (Current — Synchronous Data Path)
The only concurrency in the current pipeline is a dedicated log dispatcher
thread that drains `log_channel` and forwards entries to spdlog for the entire
run (joined during shutdown after `log_channel` closes).
`BiergartenPipelineOrchestrator::Run()` itself is synchronous — sampling,
enrichment, generation, and export all happen on the main thread.

(not a city/region-specific page). MockEnrichmentService

# The Biergarten Data Pipeline — Activity Diagram (Planned)
Each generation phase runs a producer/consumer chain concurrently: an
**Orchestrator** producer feeds a bounded channel, an **LLM Worker** consumes it
and generates records (closing its output channel when the input is drained and
closed), and a **SQLite Worker** consumes that output channel and commits in
batches. The brewery phase inserts a fourth stage, a **Geocode Worker**, between
the LLM Worker and the SQLite Worker: reverse-geocoding is network-bound and
rate-limited independently of LLM inference (Nominatim's 1-request-per-second
policy), so keeping it off the LLM Worker's thread means neither stage stalls
waiting on the other's bottleneck. The Checkin and Follow phases run in parallel
with each other once the user and brewery pools are populated.

# Biergarten Data Pipeline — Class Diagram (Planned)
```mermaid
--8<-- "pipeline/diagrams/planned/class.mmd"
```
## Notes
- `Logger`, `PipelineLogger`, and `LogWorker` are referenced only in
relationships in the source PlantUML (not given their own class blocks there
either) — they appear here as implicit nodes for the same reason.
- Package grouping from the PlantUML source (`Domain: Models`,
`Domain: Application Configuration`, `Domain: Policy`,
`Infrastructure: Logging`, `Infrastructure: Pipeline Channel`,
`Infrastructure: Data Preloading`, `Infrastructure: Enrichment`,
`Infrastructure: Prompting`, `Infrastructure: Data Generation`,
`Infrastructure: Data Export`) is preserved as Mermaid `namespace` blocks.

forename_list = std::unordered_set<ForenameEntry>
surname_list = std::unordered_set<std::string>
(aliases declared in curated_data_service.h).
ICuratedDataService::LoadForenamesByCountry() /
LoadSurnamesByCountry() each return a flat
std::unordered_map<std::string, forename_list>
or <std::string, surname_list> keyed by ISO
3166-1 country code -- no NamesByCountry
wrapper class. SampleName(forenames_by_country,
surnames_by_country, iso3166_1, rng) is a free
function, not a method, so it can be called by
any per-city worker without owning the maps.
Sourced from popular-names-by-country-dataset
(CC0) -- see ETHICS-AND-KNOWN-ISSUES.md. Gender
is preserved per forename so it can be threaded
through to persona/bio generation later; surnames
carry no gender in the source data. Pairing
happens at sample time, not at fixture-authoring
time, so no information from the source dataset
is discarded up front.

Fixed in-memory dataset used in --mocked mode,
