Migrate Auth/Brewery/Location repositories to pure Dapper; rename Timer to RowVersion (#237)

* Integrate Spectre.Console into seed application, use async data loading

* Replace stored-procedure repositories with Dapper-based repositories

Removes the USP_* stored procedures for Auth, Location, and Brewery
data access in favour of services built with Dapper.

Adds a new Features.Locations slice and optimistic concurrency support
for the Brewery slice.

* Add new documentation for Dapper migration/database schema

* Update FluentAssertions to most recent open source ver

* Update XML doc comment in backend projects

* Modify brewery location dto to include denormalized data

* - Updated column names from 'Timer' to 'RowVersion' in schema.sql for
- Introduced new BeerPost entity and updated BreweryPost and BreweryPostLocation entities to use 'RowVersion' for concurrency.
- Modified UserAccount, UserCredential, UserVerification, City, StateProvince, and Country entities to use 'RowVersion' instead of 'Timer'.
- Updated tests and command handlers to reflect changes in concurrency token from 'Timer' to 'RowVersion'.
- Adjusted BreweryDto and BreweryDtoMapper to include 'RowVersion' and updated mapping logic accordingly.
- Ensured all repository methods and interfaces are aligned with the new concurrency handling approach.

* updates

* Add BeerStyle entity and related properties; refactor BreweryDto to remove BeerPosts

* Fix Api.Specs test failures: stale Timer column refs and missing test.user fixture

* Remove repository tests, usages of registration dto used in repo

* archive old stored procs/functions

* update stale docs

* Add instructions for generating cryptographically secure base64 secrets on macOS/Linux and Windows

-- Application focuses on orchestration
+- No ORM (Entity Framework not used); each repository issues inline SQL
+  through Dapper, with no manual `IDbCommand` parameter binding. The one
+  wrinkle is the `GEOGRAPHY` column on `BreweryPostLocation`, which Dapper
+  can't deserialize as a UDT: reads select `CONVERT(varbinary(max),
+  Coordinates)` so the value comes back as a plain `byte[]` Dapper can bind
+- Referential checks that a stored procedure used to perform (e.g. "does this
+  `CityId` exist?") are now explicit `SELECT 1 ...` existence checks in the
+  repository method, run inside the same transaction as the write
+- Optimistic concurrency uses each table's `RowVersion` (`ROWVERSION`) column,
+  checked in the `UPDATE ... WHERE ... AND RowVersion = @RowVersion` clause
+- Repositories throw `Domain.Exceptions` types (`NotFoundException`,
+  `ConflictException`, ...) directly when a check fails, rather than relying on
+  a database-side `THROW`; `API.Core`'s `GlobalExceptionFilter` maps those
+  exception types to HTTP status codes
+- Application focuses on orchestration; the database enforces integrity via
+  keys, `CHECK` constraints, and cascades

-## Database Architecture
+## Database architecture
 
-### SQL-First Philosophy
+For the table-by-table schema and the custom SQL error code scheme, see
+[Database](website/database.md).
+
+### SQL-first philosophy
 
 **Principles**:
 
 1. Database is source of truth
-2. Complex queries in stored procedures
+2. Queries live in the owning repository, not scattered across the app
 3. Database handles referential integrity
 4. Application orchestrates, database executes
 
 **Benefits**:
 
 - Performance optimization via execution plans
-- Centralized query logic
+- Query logic scoped to the repository that owns it, not spread across layers
 - Version-controlled schema (migrations)
 - Easier query profiling and tuning
 
-### Migration Strategy
+### Migration strategy
 
 **Tool**: DbUp
 
 **Process**:
 
-1. Write SQL migration script
-2. Embed in `Database.Migrations` project
-3. Run migrations on startup
-4. Idempotent and versioned
+1. Write a SQL script under `Database.Migrations/scripts/`
+2. Embed it in the `Database.Migrations` project
+3. `Database.Migrations` runs each script against the target database on
+   startup, tracked so a script never re-runs once applied
 
 **Migration Files**:
 
 ```
 scripts/
-├── 001-CreateUserTables.sql
-├── 002-CreateLocationTables.sql
-├── 003-CreateBreweryTables.sql
-└── ...
+└── 01-schema/
+    └── schema.sql   # full table/index/constraint definitions
 ```
 
-### Data Seeding
+Currently the whole schema is a single versioned script. As the schema evolves,
+new numbered scripts get added alongside it rather than editing `schema.sql` in
+place, so DbUp's already-applied tracking stays valid.
 
-**Purpose**: Populate development/test databases
+### Data seeding
 
-**Implementation**: `Database.Seed` project
+**Purpose**: Populate development/test databases with realistic data
+
+**Implementation**: `Database.Seed` project, using data produced by the C++
+pipeline under `tooling/pipeline/` (see [Pipeline README](pipeline/README.md))
 
 **Seed Data**:
 
-- Countries, states/provinces, cities
-- Test user accounts
-- Sample breweries (future)
+- Countries, state/provinces, and cities (via `Features.Locations`'
+  `ILocationRepository`, which creates `Country`/`StateProvince` rows on
+  demand while resolving a city)
+- User accounts (via `Features.Auth`'s repository)
+- Brewery posts with locations (via `Features.Breweries`' repository)
 
-## Deployment Architecture
+Tables that exist in the schema but have no repository yet (`Photo`,
+`UserAvatar`, `UserFollow`, `BeerStyle`, `BeerPost`, `BeerPostPhoto`,

+surnames" and "List of most popular given names" as of the week of 2023-07-08 —

+is curated fixture data per ROADMAP.md §2. Per-forename gender from the source
+data is preserved through to the sampled `Name` (rather than discarded during
+loading) so it's available for gender-aware persona/bio generation later.
+
+The full multinational dataset is kept as-is (106 countries for forenames, 75
+for surnames) rather than trimmed to `locations.json`'s current country list, so
+it doesn't need re-sourcing if more countries are added later. `SampleName()` (a
+free helper in `generate_users.cc`) returns no result for a country present in
+neither file; of the countries in `locations.json`, that's currently `KE`, `SE`,

 ### How it works
 
-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 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.
 
-`GGML_BACKEND_PATH` is set to `/usr/local/lib` so llama.cpp knows where to scan
-for backend plugins.
+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.

+`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

+# Pipeline Roadmap — Reaching the Planned Architecture
+
+This is the engineering breakdown for closing the gap between the **current**
+pipeline and the **planned** architecture documented in
+[`diagrams/planned/class.puml`](./diagrams/planned/class.puml) and
+[`diagrams/planned/activity.puml`](./diagrams/planned/activity.puml). Nothing in
+`diagrams/planned/` is implemented yet — this file tracks what it would take to
+get there. For the current implementation, see [README.md](./README.md).
+
+Items are grouped by layer and roughly ordered by dependency: later groups build
+on types and services introduced earlier.
+
+The only concurrency in the current pipeline is the log dispatcher thread
+(`main.cc` spawns it to drain a `BoundedChannel<LogEntry>` into spdlog for the
+whole run). Sampling, enrichment, generation, and export all happen
+synchronously on the main thread inside `BiergartenPipelineOrchestrator::Run()`
+— §6 below is what introduces the additional worker threads the planned
+architecture needs.
+
+---
+
+## 1. Domain Models
+
+`tooling/pipeline/includes/data_model/generated_models.h` and `models.h`.
+
+- [ ] Add `Completeness` enum (`Full`, `Partial`, `Absent`) and a
+      `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.

+SQL Server 2022 schema, migration approach, and the app's SQL error-handling
+convention. For the vertical-slice code that talks to this schema, see
+[Architecture](../architecture.md).
+
+## Schema
+
+The full schema lives in one script:
+`web/backend/Database/Database.Migrations/scripts/01-schema/schema.sql`, run by
+`Database.Migrations` (DbUp) on startup. Each table is queried directly by the
+owning feature slice's repository (see
+[Direct SQL via Dapper/ADO.NET](../architecture.md#direct-sql-via-dapperadonet)).
+
+All tables use a `UNIQUEIDENTIFIER` primary key defaulting to `NEWID()`, and
+most carry a `RowVersion ROWVERSION` column used for optimistic concurrency on
+updates (`UPDATE ... WHERE ... AND RowVersion = @RowVersion`).
+
+### Tables backed by the API today

+| `BeerPostPhoto`    | Links a `BeerPost` to a `Photo`                                                                          |

+
+## Migrations
+
+**Tool**: DbUp, run by the `Database.Migrations` project/container.
+
+Scripts live under `scripts/`, applied in order and tracked so a script never
+re-runs once it has succeeded. Today that's a single `01-schema/schema.sql`.
+When the schema needs to change, add a new numbered script rather than editing
+`schema.sql` in place — DbUp's tracking is per-script, so editing an
+already-applied script means it won't re-run against existing databases.
+
+## Data seeding
+
+`Database.Seed` populates a target database from data produced by the C++
+pipeline (see [Pipeline README](../pipeline/README.md)): countries,
+state/provinces, and cities (created on demand while resolving each brewery's
+location), user accounts, and brewery posts with locations. It only seeds
+tables that have a feature slice to write through (see the table above).
+
+## Database error handling
+
+- Optimistic-concurrency conflicts are detected by an `UPDATE` affecting zero
+  rows against the `RowVersion` column.
+- On failure, the repository throws a `Domain.Exceptions` type directly
+  (`NotFoundException`, `ConflictException`, `ArgumentException`, ...).
+  `API.Core`'s `GlobalExceptionFilter` maps these to HTTP status codes (404,
+  409, 400, ...); an unmapped `SqlException` (e.g. a genuine connectivity or
+  constraint-violation failure) maps to 503.
+
+  - One repository-level exception: `Features.Auth`'s `AuthRepository` does
+    catch `SqlException` directly, to detect a duplicate-key race (SQL Server
+    error 2601 or 2627) when two requests try to verify the same account
+    concurrently — see `Auth Repository.IsDuplicateVerificationViolation`.
