 ## Backend Architecture
 
-### Vertical Slice Architecture Pattern
+### Layered Architecture Pattern
 
-The backend organizes business capabilities as feature slices instead of
-technical layers. Each feature (`Features.Auth`, `Features.Breweries`,
-`Features.UserManagement`, `Features.Emails`) is a single project that owns
-its own controller, MediatR commands/queries/handlers, validators, and
-repository, end to end:
+The backend follows a strict layered architecture:

-Slices never reference each other's project. The one cross-slice
-interaction (`Features.Auth` triggering a confirmation email handled by
-`Features.Emails`) goes through a MediatR command (`SendRegistrationEmailCommand`)
-whose contract lives in `Shared.Application`, so neither slice takes a
-project reference on the other.
-
 ### Layer Responsibilities
 
 #### API Layer (`API.Core`)
 
-**Purpose**: Thin ASP.NET Core host: no business logic, no controllers of
-its own
+**Purpose**: HTTP interface and request handling
 
 **Components**:
 
-- `Program.cs`: registers MediatR (scanning every `Features.*` assembly),
-  FluentValidation, and uses `AddApplicationPart` so each slice's controllers
-  are discovered by MVC
-- `GlobalException.cs`: global exception filter (host-level cross-cutting
-  concern)
-- `Authentication/JwtAuthenticationHandler.cs`: JWT auth scheme middleware
-- Swagger/OpenAPI documentation, health check endpoints
+- Controllers (`AuthController`, `UserController`)
+- Middleware for error handling
+- Swagger/OpenAPI documentation
+- Health check endpoints
 
 **Dependencies**:
 
-- Every `Features.*` project (for controller/MediatR discovery)
-- `Shared.Contracts`, `Shared.Application`
-- `Infrastructure.Jwt` (for the auth middleware)
+- Service layer
+- ASP.NET Core framework
 
 **Rules**:
 
-- No controllers, no business logic, no feature-specific contracts
-- Exists purely to host and wire up the feature slices
+- No business logic
+- Only request/response transformation
+- Delegates all work to Service layer
 
-#### Feature Slices (`Features.Auth`, `Features.Breweries`, `Features.UserManagement`, `Features.Emails`)
+#### Service Layer (`Service.Auth`, `Service.UserManagement`)
 
-**Purpose**: Each slice is the complete vertical for one business capability
-
-**Components** (per slice):
-
-- `Controllers/`: HTTP endpoints, binding directly to Command/Query types
-  as the request contract
-- `Commands/<Operation>/` and `Queries/<Operation>/`: one folder per
-  operation, each containing the Command/Query record, its
-  `IRequestHandler`, and (for commands) a FluentValidation validator
-- `Repository/`: the slice's own stored-procedure repository
-  implementation
-- `Dtos/`: response shapes returned by query handlers (never the raw
-  domain entity)
-- `DependencyInjection/`: an `AddFeaturesX()` extension method registering
-  the slice's repository/services
-
-`Features.Emails` has no `Controllers/` folder. It's invoked only via
-MediatR commands sent from other slices, never over HTTP.
-
-**Dependencies**:
-
-- `Domain.Entities`, `Domain.Exceptions`
-- `Infrastructure.Sql` (generic ADO.NET plumbing) plus whichever
-  infrastructure project the slice needs (`Infrastructure.Jwt`/
-  `Infrastructure.PasswordHashing` for Auth, `Infrastructure.Email`/
-  `Infrastructure.Email.Templates` for Emails)
-- `Shared.Contracts`, `Shared.Application`
-- **Never** another `Features.*` project
-
-**Rules**:
-
-- All business logic for that feature lives in its command/query handlers
-- No direct controller-to-repository calls; everything flows through
-  MediatR
-- Read endpoints return a dedicated `Dto`, never the domain entity directly
-
-#### Shared Projects (`Shared.Contracts`, `Shared.Application`)
-
-**Purpose**: The minimum cross-slice surface area required because every
-slice needs it, or because duplicating it four times would be worse than
-sharing it
+**Purpose**: Business logic and orchestration
 
 **Components**:
 
-- `Shared.Contracts`: `ResponseBody<T>`/`ResponseBody`, the API response
-  envelope every controller returns
-- `Shared.Application`: `ValidationBehavior<TRequest,TResponse>` (the
-  MediatR pipeline behavior that runs FluentValidation before a handler
-  executes) and the cross-slice email commands
-  (`SendRegistrationEmailCommand`, `SendResendConfirmationEmailCommand`)
+- Authentication services (login, registration)
+- User management services
+- Business rule validation
+- Transaction coordination
+
+**Dependencies**:
+
+- Infrastructure layer (repositories, JWT, password hashing)
+- Domain entities
 
 **Rules**:
 
-- Kept deliberately small: this is the exception to "no slice depends on
-  another slice," not a general-purpose dumping ground
+- Contains all business logic
+- Coordinates multiple infrastructure components
+- No direct database access (uses repositories)
+- Returns domain models, not DTOs
 
 #### Infrastructure Layer
 
-**Purpose**: Technical capabilities and external integrations, shared by
-whichever slices need them
+**Purpose**: Technical capabilities and external integrations
 
 **Components**:
 
-- **Infrastructure.Sql**: generic ADO.NET connection/command plumbing
-  (`ISqlConnectionFactory`, the abstract `Repository<T>` base class), not
-  domain-specific; each slice's own `Repository/` folder builds on this
+- **Infrastructure.Repository**: Data access via stored procedures
 - **Infrastructure.Jwt**: JWT token generation and validation
 - **Infrastructure.PasswordHashing**: Argon2id password hashing
-- **Infrastructure.Email**: Email sending capabilities (SMTP/MailKit)
-- **Infrastructure.Email.Templates**: Email template rendering (Razor
-  components)

 ### Design Patterns
 
-#### Vertical Slice + MediatR
-
-**Purpose**: Organize code by feature instead of by technical layer, so
-everything needed to understand or change one capability lives in one
-project
-
-**Implementation**:
-
-- Each HTTP write operation is a `Command` (e.g. `CreateBreweryCommand` in
-  `Features.Breweries/Commands/CreateBrewery/`); each read operation is a
-  `Query` (e.g. `GetBreweryByIdQuery`)
-- Controllers bind directly to the Command/Query as the request body;
-  there is no separate request DTO + mapping step for writes
-- A single shared `ValidationBehavior<TRequest,TResponse>`
-  (`Shared.Application/Behaviors/`) runs FluentValidation validators in the
-  MediatR pipeline before any handler executes
-- Query handlers map to a dedicated response `Dto`, so domain entities never
-  leak over the wire
-
-**Example**:
-
-```csharp
-public record CreateBreweryCommand(Guid PostedById, string BreweryName, string Description, ...)
-    : IRequest<BreweryDto>;
-
-public class CreateBreweryHandler(IBreweryRepository repository) : IRequestHandler<CreateBreweryCommand, BreweryDto>
-{
-    public async Task<BreweryDto> Handle(CreateBreweryCommand request, CancellationToken cancellationToken) { ... }
-}
-```

 #### Repository Pattern

-**Implementation**: each slice owns its own repository, scoped to that
-feature only:
+**Implementation**:
 
-- `Features.Auth/Repository/IAuthRepository.cs`
-- `Features.Breweries/Repository/IBreweryRepository.cs`

-- `Infrastructure.Sql/DefaultSqlConnectionFactory.cs`: the generic
-  connection factory every slice's repository builds on
+- `IAuthRepository` - Authentication queries
+- `IUserAccountRepository` - User account queries
+- `DefaultSqlConnectionFactory` - Connection management

 ### How it works
 
-The container uses a two-stage build. The builder stage installs CMake/Ninja,
-clones the matching llama.cpp release tag for its headers only (installed into
-`/usr/local/include`), and copies prebuilt shared libraries (`libllama`,
-`libggml`, and CUDA/CPU backend plugins) from `ghcr.io/ggml-org/llama.cpp:full-cuda`
-into `/usr/local/lib`. With both headers and libraries present, CMake's
-system-library detection (see [Build](#build) above) finds them and skips the
-FetchContent source build, keeping image build times short.
+The container uses a two-stage build. The first stage pulls prebuilt
+`libllama`, `libggml`, and backend plugin libraries (including `libggml-cuda.so`
+and the CPU variant plugins) from `ghcr.io/ggml-org/llama.cpp:full-cuda`. The
+second stage copies those libraries into `/usr/local/lib` and runs `ldconfig` so
+the dynamic linker and `dlopen` calls from `ggml_backend_load_all()` can resolve
+the CUDA backend plugin at runtime. llama.cpp headers are cloned at the matching
+tag and installed into `/usr/local/include`. CMake auto-detects both and skips
+the FetchContent source build entirely, keeping image build times short.
 
-The runtime stage copies the compiled binary, the same prebuilt shared
-libraries, and config/prompt assets into a slim CUDA runtime image. It sets
-`LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH` so the dynamic linker
-resolves `libllama`/`libggml` at startup, and also co-locates
-`libggml-cuda.so` and the CPU backend plugins next to the binary for
-`ggml_backend_load_all()`'s `dlopen` scan.
+`GGML_BACKEND_PATH` is set to `/usr/local/lib` so llama.cpp knows where to scan
+for backend plugins.

 ### Key Components
 
 - `src/main.cc` — argument parsing and Boost.DI composition root.
-- `CuratedJsonDataService` — implements `ICuratedDataService`; takes a
-  `CuratedDataFilePaths` DTO (locations/personas/forenames/surnames paths) in
-  its constructor, then parses and validates curated location, persona, and
-  forename/surname JSON, memoizing each result after its first load on a
-  given instance. `MockCuratedDataService` is the in-memory substitute (4
-  fixed locations, 3 personas, and name data for `US`/`DE`/`FR`/`BE`) used in
-  `--mocked` runs.
-- `WikipediaEnrichmentService` — queries Wikipedia extracts, caches results,
-  returns empty context on failure. `MockEnrichmentService` is the no-op
-  substitute used in `--mocked` runs.
-- `LlamaGenerator` — formats prompts for Gemma 4, validates JSON output for
-  both `GenerateBrewery` and `GenerateUser`, retries malformed responses up
-  to three times with corrective feedback in the retry prompt. The token
-  budget is fixed across attempts; it is not raised automatically on
-  truncation.
-- `MockGenerator` — stable hash-based output so the same city/persona/name
-  input always produces the same brewery or user.
-- `SqliteExportService` — creates a dated SQLite file per run and persists
-  each successful user and brewery into normalized tables.

 ### Runtime Behaviour
 
-`WikipediaEnrichmentService` fetches two Wikipedia extracts per city: a
-generic "brewing" extract and a "beer in `{country}`" extract. It does not
-currently query a city- or region-specific page. Each query string is cached
-after its first successful (or empty) lookup.
+`WikipediaService` queries city, country, and beer-related Wikipedia extracts
+using its configured lookup, then caches the first successful response per query
+string. The fetched extract text is included in the prompt as context for
+generation.
 
 `GetLocationContext()` returns an empty string when the web client is
 unavailable or when lookup/parsing fails.
 
-`LlamaGenerator` validates model output as structured JSON. On validation
-failure it retries up to three times, replaying the previous error message in
-the next prompt so the model can self-correct. All runs to date have produced
-valid output on the first pass; the retry path is kept for resilience.
+`LlamaGenerator` validates model output as structured JSON. The retry path
+exists as a safety hatch for cases where the reasoning block consumes available
+token budget and compresses the JSON output space. All runs to date have
+produced valid output on the first pass; the path is kept for resilience.
 
 `MockGenerator` uses stable hashes for repeatable output in demos and Storybook
 runs.
 
-`CuratedJsonDataService` memoizes each of `LoadLocations()`, `LoadPersonas()`,
-`LoadForenamesByCountry()`, and `LoadSurnamesByCountry()` independently the
-first time each is called, since `BiergartenPipelineOrchestrator` owns a
-single `ICuratedDataService` instance for the whole run — later calls return
-the cached result instead of re-parsing. 
-
-`GenerateUsers()` samples a forename/surname pair per city via `SampleName()`,
-keyed by the city's ISO 3166-1 code. Countries present in `locations.json`
-but absent from either name fixture (currently `KE`, `SE`, `SG`, `TH`, `VN`,

-      `LocationContext` struct (`text`, `completeness`, `char_count`).
-      Replace `EnrichedCity::region_context` (currently a plain
-      `std::string`) with `context : LocationContext`.
-- [ ] Add `BeerStyle` (`name`, `description`, `min_abv`, `max_abv`,
-      `min_ibu`, `max_ibu`).
-- [ ] Add `BeerResult`, `CheckinResult`, `RatingResult` result payloads.
-- [ ] Add `GenerationMetadata` (`generation_id`, `generated_time`,
-      `context_provided`, `generated_with`).
-- [x] Add `first_name`, `last_name`, `gender`, and `activity_weight` to
-      `UserResult` (currently just `username`, `bio`). `first_name`/
-      `last_name`/`gender` are copied from the sampled `Name` (see below),
-      not LLM-invented.
-- [x] Add `Name` (`first_name`, `last_name`, `gender`) — the sampled result
-      handed to `DataGenerator::GenerateUser`. Add `ForenameEntry` (`name`,
-      `gender`). Landed as a flatter shape than originally planned here: no
-      `NamesByCountry` wrapper class. `curated_data_service.h` instead
-      declares `ForenameList = std::vector<ForenameEntry>` and
-      `SurnameList = std::vector<std::string>`, and
-      `ICuratedDataService` exposes two maps keyed by ISO 3166-1 code —
-      `ForenamesByCountryMap = unordered_map<string, ForenameList>` and
-      `SurnamesByCountryMap = unordered_map<string, SurnameList>` —
-      directly (see §2). Sampling is
-      a free function, `SampleName(forenames_by_country,
-      surnames_by_country, iso3166_1, rng)`, in
-      `generate_users.cc`'s anonymous namespace, not a method on a class.
-      Pairing a forename with a surname happens at sample time so gender
-      (present per-forename in the source data) is never discarded the way a
-      pre-flattened `{first_name, last_name}` list would lose it; see §2.
-- [ ] Extend `GeneratedBrewery` with `brewery_id`, `context_completeness`,
-      `metadata` (currently just `{location, brewery}`).
-- [ ] Add `GeneratedBeer`, `GeneratedCheckin`, `GeneratedRating`,
-      `GeneratedFollow` aggregate structs.
-- [x] Add `UserRecord` (`location`, `user : UserResult`, `email`,
-      `date_of_birth`) as the current stand-in for the planned
-      `GeneratedUser` — `email` and `date_of_birth` are programmatically
-      generated by the orchestrator, never LLM-authored, so a downstream
-      auth-account seeding consumer can register real accounts from the
-      pipeline's SQLite export. No `password`, `user_id`, or `metadata`
-      field yet, matching `BreweryRecord`'s equally pre-`metadata` shape.
-      Already wired into `IExportService`/`SqliteExportService`: a `users`
-      table exists and `GenerateUsers()` exports each successful record via
-      `ProcessRecord(const UserRecord&)` (see §5) in addition to logging and
-      holding `generated_users_` in memory. Still missing vs. the planned
-      `GeneratedUser`: `user_id`, `password`, and `metadata`.
-- [x] Add `UserPersona` (`name`, `description`, `style_affinities`).
-
-## 2. Data Preloading
-
-`tooling/pipeline/includes/services/curated_data/`, fixture files.
-
-- [x] Extract an interface; have `CuratedJsonDataService` implement it.
-      Landed as `ICuratedDataService`
-      (`services/curated_data/curated_data_service.h`), not `DataPreloader`
-      — `LoadLocations()`, `LoadPersonas()`, `LoadForenamesByCountry()`, and
-      `LoadSurnamesByCountry()` are all virtual methods returning `const&`
-      and take no arguments. `CuratedJsonDataService`
-      (`services/curated_data/curated_json_data_service.h`, originally
-      landed as `JsonLoader` under `json_handling/` before being renamed and
-      moved) takes a `CuratedDataFilePaths` DTO (`locations_path`,
-      `personas_path`, `forenames_path`, `surnames_path`) in its
-      constructor rather than a path per `Load*()` call, and memoizes each
-      result in a private `cache` struct (`locations`, `personas`,
-      `forenames_by_country`, `surnames_by_country`), so a second call on
-      the same instance returns the cached result instead of re-parsing —
-      safe because `CuratedJsonDataService` outlives every call site (owned
-      by `BiergartenPipelineOrchestrator` via
-      `unique_ptr<ICuratedDataService>` for the whole run). `main.cc`'s DI
-      injector also gained a `MockCuratedDataService` (fixed in-memory
-      data: 4 locations across `US`/`DE`/`FR`/`BE`, 3 personas, and
-      matching forename/surname sets for those four countries), bound in
-      place of `CuratedJsonDataService` under `--mocked`, mirroring the
-      existing `MockEnrichmentService`/`MockGenerator` pattern.
-- [ ] Add `LoadBeerStyles()`. `beer-styles.json` already exists in the repo
-      and is already copied into the Docker image
-      (`runpod/Dockerfile`), but no loader reads it yet, and the native
-      CMake build doesn't copy it into `build/` at all — `CMakeLists.txt`'s
-      "Runtime Assets" step only copies `locations.json` and `prompts/`.
-- [x] Add `LoadPersonas()` and author `personas.json` (doesn't exist yet).
-- [x] Add name-by-country loading, parsing
-      `tooling/pipeline/forenames-by-country.json` and
-      `surnames-by-country.json`. Landed as two separate methods —
-      `LoadForenamesByCountry()` and `LoadSurnamesByCountry()` — each
-      returning a flat `ForenamesByCountryMap` / `SurnamesByCountryMap`
-      (aliases for `unordered_map<string, ForenameList>` /
-      `unordered_map<string, SurnameList>`) keyed by ISO 3166-1 code, rather
-      than one combined `LoadNamesByCountry() : NamesByCountry` call. Both
-      files are vendored verbatim (unmodified,
-      full multinational coverage) from
-      `sigpwned/popular-names-by-country-dataset` (CC0) — see
-      ETHICS-AND-KNOWN-ISSUES.md's Names-by-Country Dataset section for
-      provenance. Deliberately not pre-paired or filtered down to just the
-      countries in `locations.json`: keeping the source shape (including
-      per-forename gender) intact means the loader can support more
-      countries later, or gender-aware persona/bio generation, without
-      re-sourcing data.
-
-## 3. Policy / Strategy Layer
-
-Entirely new — no `includes/policy/` (or equivalent) directory exists today.
-
-- [ ] `ContextStrategy` interface + `BreweryContextStrategy` /
-      `BeerContextStrategy`. Today `WikipediaEnrichmentService::GetLocationContext`
-      hardcodes a generic `"brewing"` query and a `"beer in {country}"`
-      query directly — no per-phase strategy selection.
-- [ ] `SamplingStrategy` interface + `UniformSamplingStrategy`, replacing
-      the inline `std::ranges::sample(...)` call in
-      `BiergartenPipelineOrchestrator::QueryCitiesWithCountries()`.
-- [ ] `BeerSelectionStrategy` interface + `RandomBeerSelectionStrategy`, to
-      pick styles per brewery from the `BeerStyle` palette (depends on §1
-      and §2).
-- [ ] `CheckinDistributionStrategy` interface + `JCurveCheckinStrategy` /
-      `RandomCheckinStrategy` — this is the "Check-In System" item already
-      called out in README.md's Next Steps, made concrete.
-- [ ] `FollowGenerationStrategy` interface + `RandomFollowStrategy` /
-      `ActivityWeightedFollowStrategy`.
-
-## 4. Data Generation
-
-`tooling/pipeline/includes/data_generation/`, `src/data_generation/`.
-
-- [ ] Extend the `DataGenerator` interface with `GenerateBeer`,
-      `GenerateCheckin`, `GenerateRating` (today: only `GenerateBrewery` and
-      `GenerateUser`).
-- [x] Implement `LlamaGenerator::GenerateUser` for real, with a retry loop
-      mirroring `GenerateBrewery` (GBNF grammar, `ValidateUserJson`, up to 3
-      attempts with corrective feedback) and a new
-      `prompts/USER_GENERATION.md`. Changed the `DataGenerator::GenerateUser`
-      signature to
-      `(city : const EnrichedCity&, persona : const UserPersona&, name : const Name&) : UserResult`,
-      matching what the activity diagram actually passes. `MockGenerator::GenerateUser`
-      updated to match the new signature too.
-- [ ] Implement `MockGenerator::GenerateBeer` / `GenerateCheckin` /
-      `GenerateRating`.
-- [ ] Add `IPromptFormatter::ExpectedArchitecture()` and
-      `LlamaGenerator::ValidateModelArchitecture()` so loading a GGUF that
-      doesn't match the configured chat template fails fast instead of
-      silently producing degraded output.
-- [ ] Add prompt template files for beer/checkin/rating generation next to
-      the existing `prompts/BREWERY_GENERATION.md`.
-
-## 5. Export Service
-
-`tooling/pipeline/includes/services/database/`, `src/services/sqlite/`.
-
-- [x] `IExportService::ProcessRecord(const UserRecord&)` and
-      `SqliteExportService`'s `users` table (see
-      `kCreateUsersTableSql` / `kInsertUserSql` in
-      `includes/services/database/sqlite_statement_helpers.h`) are
-      implemented — `GenerateUsers()` exports every successful user
-      alongside its resolved `location_id`.
-- [ ] Extend `IExportService` with `ProcessBeer`, `ProcessCheckin`,
-      `ProcessRating`, `ProcessFollow` (today `ProcessRecord(const
-      BreweryRecord&)` and `ProcessRecord(const UserRecord&)` exist).
-- [ ] Add `beers`, `checkins`, `ratings`, `follows` tables to
-      `SqliteExportService::InitializeSchema()` (`locations`, `breweries`,
-      and `users` already exist) — see `kCreateLocationsTableSql` /
-      `kCreateBreweriesTableSql` / `kCreateUsersTableSql` in
-      `includes/services/database/sqlite_statement_helpers.h` for the
-      existing pattern to follow.
-- [ ] Add a `brewery_cache_` alongside the existing `location_cache_`, and
-      move from one open transaction for the whole run to per-phase batched
-      commits (`BEGIN` / `COMMIT & BEGIN` on a batch-size threshold), as
-      shown in the planned activity diagram.
-
-## 6. Concurrency & Orchestration
-
-`tooling/pipeline/includes/concurrency/`,
-`src/biergarten_pipeline_orchestrator/`.
-
-- [ ] `BoundedChannel<T>` already exists and is production-tested — but
-      it's only wired to the single log channel today. Stand up the
-      per-phase producer/consumer channels (`loc_ch`, `exp_ch`, etc.) the
-      planned activity diagram describes, each with a dedicated LLM worker
-      thread and SQLite worker thread.
-- [ ] Rewrite `BiergartenPipelineOrchestrator::Run()` from one synchronous
-      pass over `generated_breweries_` into phased methods —
-      `RunUserPhase` → `RunBreweryAndBeerPhase` (with a `RunBeerPhase`
-      sub-step once `brewery_pool_` is populated) → `RunCheckinPhase` /
-      `RunFollowPhase` (these two can run in parallel) → `RunRatingPhase` —
-      backed by `user_pool_`, `brewery_pool_`, `beer_pool_`,
-      `checkin_pool_`, `follow_pool_`.
-- [ ] Honor the structural-concurrency requirement already called out in a
-      comment on `BiergartenPipelineOrchestrator::Run()` in
-      `biergarten_pipeline_orchestrator.h`: once real worker threads exist,
-      they must be structurally joined (e.g. via `std::jthread`) before
-      `Run()` returns, so no worker logs to a closed channel during
-      teardown.
-
-## 7. Enrichment
-
-- [ ] Decide whether to restore the city/region-specific Wikipedia query
-      that's currently commented out in
-      `src/services/enrichment/wikipedia/get_summary.cc`
-      (`GetLocationContext`). The `ContextStrategy` work in §3 is a natural
-      place to reintroduce it via `BreweryContextStrategy::QueriesFor()`.
-- [ ] Pre-warm caches at startup (`PreWarmBeerStyleCache`,
-      `PreWarmLocationCache` in the planned activity diagram) instead of
-      fetching lazily per record, so the streaming phases never block on a
-      cold cache mid-run.
-
-## 8. Fixtures / Build
-
-- [x] Author `personas.json`, `forenames-by-country.json`, and
-      `surnames-by-country.json` (see §2).
-- [ ] Fix the `beer-styles.json` build-tree gap: add it to the "Runtime
-      Assets" `configure_file` step in `CMakeLists.txt` so native builds and
-      the Docker image agree on what's available at runtime.
-
----
-
-## Suggested build order
-
-The planned activity diagram's own phase notes ("brewery*pool* is now fully
-populated. Phase 1b may begin.", etc.) imply a dependency order. Roughly:
-
-1. Domain models (§1) and data preloading (§2) — nothing else compiles
-   without these.
-2. Export schema (§5) — so every later generation phase has somewhere to
-   land its output.
-3. Policy/strategy layer (§3) and generator interface (§4).
-4. Concurrency/orchestration rewrite (§6), which is the only piece that
-   actually wires §1–§5 into the phased, parallel pipeline shown in the
-   planned diagrams.
-5. Enrichment cache pre-warming and the city/region query decision (§7) —
-   useful at any point, but most valuable once phases run concurrently.

-# FULL SYSTEM PROMPT
-
-You are a craft beer community profile writer. You write short, first-person
-biographies for fictional users of a brewery-discovery app, grounded in the
-exact name, locale, and persona provided. You do not invent the user's name --
-it is given to you and must not be altered, translated, or abbreviated beyond
-forming a username.
-
-You will receive the inputs like this:
-
-## NAME:
-
-[First name] [Last name]
-
-## GENDER:
-
-[Gender associated with the given first name]
-
-## CITY:
-
-[City Name]
-
-## COUNTRY:
-
-[Country Name]
-
-## PERSONA:
-
-[Persona archetype name]
-
-## PERSONA DESCRIPTION:
-
-[What this persona cares about and how they talk about beer]
-
-## STYLE AFFINITIES:
-
-[Comma-separated beer styles this persona favors]
-
-## CRITICAL OUTPUT FORMAT (READ CAREFULLY):
-
-ABSOLUTELY NO MARKDOWN FORMATTING. Do NOT wrap your response in json or ```
-blocks.
-
-Do not add markdown, code fences, or postscript around the final JSON object.
-Do not say "Here is the JSON" or "Enjoy!".
-
-The JSON must contain exactly three keys ("username", "bio",
-"activity_weight") in that order. Do not rename or add any other keys.
-
-ESCAPE ALL QUOTES inside the bio field using \", or use single quotes (' ')
-instead.
-
-DO NOT use actual line breaks (\n) inside any string. Keep the bio as one
-continuous string.
-
-The bio must be between 25 and 60 words, written in first person, and must
-read as something this specific person would write about themselves -- not a
-generic profile blurb.
-
-`activity_weight` is a number between 0 and 1 (inclusive) representing how
-often this persona checks in at breweries relative to other users. Persona
-archetypes implying frequent, habitual brewery visits should skew higher;
-casual or occasional-visitor personas should skew lower. Do not default to
-0.5 -- vary it meaningfully based on the persona description.
-
-Expected JSON format:
-
-```json
-{
-  "username": "a handle derived from the given name",
-  "bio": "The first-person bio goes here.",
-  "activity_weight": 0.62
-}
-```
-
-## CONTENT RULES AND CONSTRAINTS:
-
-### THE USERNAME:
-
-Derive the username from the given first and/or last name (e.g. lowercase,
-abbreviated, or combined with a short word or number tied to the persona's
-style affinities). Do not invent an unrelated handle. Do not include spaces.
-
-### THE BIO:
-
-Ground the bio in the supplied persona description and style affinities --
-mention at least one specific beer style from the style affinities list, in a
-way that sounds like a personal preference rather than a list. Reference the
-city or country naturally if it fits, but do not force it.
-
-### VOICE & PERSPECTIVE:
-
-Write in the first person ("I"/"my"). The tone should match the persona:
-an enthusiastic explorer sounds different from a relaxed, easy-drinking
-regular. Do not write in second or third person.
-
-### THE BLOCKLIST (FORBIDDEN CONCEPTS):
-
-You absolutely cannot use the following words and phrases. Make sure your
-final output doesn't have any of these:
-
-- "hidden gem"
-- "passion"
-- "authentic"
-- "craft beer enthusiast"
-- "beer connoisseur"
-- "journey"
-
-#### FORBIDDEN WRITING PATTERNS
-
-The following patterns are common AI writing pitfalls and must not appear in
-the bio:
-
-- Negative parallelism constructions: "It's not X, it's Y"
-- Inflated significance phrases: "stands as a testament," "plays a vital
-  role," "deeply rooted"
-- Superficial trailing analyses: sentences ending in -ing words that add
-  opinion without content
-- Promotional travel-copy tone: "breathtaking," "must-visit," "vibrant"
-- Overused conjunctive transitions used as sentence openers: "Moreover,"
-  "Furthermore," "In addition"
-- Rule of three: do not consistently organise ideas or examples in triplets
