# TODO List for Tercul Go Application

---

## [ ] Performance Improvements

- [ ] Implement batching for Weaviate operations (Medium, 2d)

## [ ] Security Enhancements

- [ ] Add comprehensive input validation for all GraphQL mutations (High, 2d)

## [ ] Code Quality & Architecture

- [ ] Expand Weaviate client to support all models (Medium, 2d)
- [ ] Add code documentation and API docs (Medium, 2d)

## [ ] Architecture Refactor (DDD-lite)

- [ ] Create skeleton packages: `cmd/`, `internal/platform/`, `internal/domain/`, `internal/app/`, `internal/data/`, `internal/adapters/graphql/`, `internal/jobs/`
- [x] Move infra to `internal/platform/*` (`config`, `db`, `cache`, `auth`, `http`, `log`, `search`)
- [ ] Wire DI in `cmd/api/main.go` and expose an `Application` facade to adapters
- [ ] Unify GraphQL under `internal/adapters/graphql` and update `gqlgen.yml`; move `schema.graphqls` and resolvers
- [ ] Resolvers call application services only; add dataloaders per aggregate
- [ ] Introduce Unit-of-Work: `platform/db.WithTx(ctx, func(ctx) error)` and repo factory for `*sql.DB` / `*sql.Tx`
- [ ] Split write vs read paths for `work` (commands.go, queries.go); make read models cacheable
- [ ] Replace bespoke cached repositories with decorators in `internal/data/cache` (reads only; deterministic invalidation)
- [ ] Restructure `models/*` into domain aggregates with constructors and invariants
- [ ] Adopt migrations tool (goose/atlas/migrate); move SQL to `internal/data/migrations`; delete `migrations.go`
- [ ] Observability: centralize logging; add Prometheus metrics and OpenTelemetry tracing; request IDs
- [ ] Config: replace ad-hoc config with env parsing + validation (e.g., koanf/envconfig); no globals
- [ ] Security: move JWT/middleware to `internal/platform/auth`; add authz policy helpers (e.g., `CanEditWork`)
- [ ] Search: move Weaviate client/schema to `internal/platform/search`, optional domain interface
- [ ] Background jobs: move to `cmd/worker` and `internal/jobs/*`; ensure idempotency and lease
- [ ] Python ops: move scripts to `/ops/migration` and `/ops/analysis`; keep outputs under `/ops/migration/outputs/`
- [ ] Cleanup: delete dead packages (`store`, duplicate `repositories`); consolidate to `internal/data/sql`
- [ ] CI: add `make lint test test-integration` and integration tests with Docker compose

## [ ] Testing

- [ ] Add unit tests for all models, repositories, and services (High, 3d)
- [ ] Add integration tests for GraphQL API and background jobs (High, 3d)
- [ ] Add performance benchmarks for critical paths (Medium, 2d)
  - [ ] Add benchmarks for text analysis (sequential vs concurrent) and cache hit/miss rates

## [ ] Monitoring & Logging

- [ ] Add monitoring for background jobs and API endpoints (Medium, 2d)
  - [ ] Add metrics for linguistics: analysis duration, cache hit/miss, provider usage

## [ ] Next Objective Proposal

- [ ] Stabilize non-linguistics tests and interfaces (High, 2d)
  - [ ] Fix `graph` mocks to accept context in service interfaces
  - [ ] Update `repositories` tests (missing `TestModel`) and align with new repository interfaces
  - [ ] Update `services` tests to pass context and implement missing repo methods in mocks
- [ ] Add performance benchmarks and metrics for linguistics (Medium, 2d)
  - [ ] Benchmarks for AnalyzeText (provider on/off, concurrency levels)
  - [ ] Export metrics and dashboards for analysis duration and cache effectiveness
- [ ] Documentation (Medium, 1d)
  - [ ] Document NLP provider toggles and defaults in README/config docs
  - [ ] Describe SRP/DRY design and extension points for new providers
