+## [ ] 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)
-  - [x] Added unit tests for linguistics adapters (lingua-go, GoVADER) and utilities
   - [ ] Add benchmarks for text analysis (sequential vs concurrent) and cache hit/miss rates
 
-## [x] Monitoring & Logging
+## [ ] Monitoring & Logging
 
-- [x] **COMPLETED: Integrate a structured logging framework** (Medium, 1d)
