# Progress

Tracks implementation progress against the phases in `PROJECT_PLAN.md`.

## Phase 1: Foundation — COMPLETE

**Deliverables:**
- [x] Go module (`go.mod`) at `git.wntrmute.dev/kyle/exo`
- [x] `core` package: `Header`, `Metadata`, `Value`, `ObjectType`, `NewUUID`, `MapFromList`/`ListFromMap`
- [x] SQLite migration framework with embedded SQL files (`db/migrations/`)
- [x] Initial schema migration (`001_initial.sql`): 13 tables covering shared infrastructure, bibliographic, and artifact repository
- [x] Database access layer: `Open` (with WAL, foreign keys, busy timeout), `StartTX`/`EndTX`, `ToDBTime`/`FromDBTime`
- [x] `config` package: `Config` struct with paths for database, blob store, Minio endpoint, gRPC listen address
- [x] `.golangci.yaml` — strict linting (errcheck, govet, gosec, staticcheck, revive, errorlint)
- [x] `Makefile` — vet, lint, test, build targets
- [x] Full test coverage for all packages (core, db, config)

**Files created:**
- `go.mod`, `go.sum`
- `core/core.go`, `core/core_test.go`
- `db/db.go`, `db/db_test.go`, `db/migrations/001_initial.sql`
- `config/config.go`, `config/config_test.go`
- `.golangci.yaml`, `Makefile`

## Phase 2: Artifact Repository — COMPLETE

**Deliverables:**
- [x] `artifacts` package: `Artifact`, `Snapshot`, `BlobRef`, `Citation`, `Publisher` types with `Get`/`Store` methods
- [x] `MIME` type alias for clarity
- [x] Tag and category management: `CreateTag`/`GetTag`/`GetAllTags`, `CreateCategory`/`GetCategory`/`GetAllCategories`, `GetArtifactIDsForTag`
- [x] Metadata store/retrieve operations (`StoreMetadata`/`GetMetadata`)
- [x] `blob` package: Content-addressable blob store (SHA256 hashing, hierarchical directory layout, read/write/exists)
- [x] YAML import: `ArtifactYAML`, `SnapshotYAML`, `CitationYAML` with `ToStd()` conversions and `LoadArtifactFromYAML`
- [x] Protobuf message definitions for all artifact types (`proto/exo/v1/common.proto`, `proto/exo/v1/artifacts.proto`)
- [x] gRPC service: `ArtifactService` with create/get artifacts, store/retrieve blobs, manage tags/categories, search by tag
- [x] `server` package: Full gRPC service implementation with proto-domain conversion helpers
- [x] buf.yaml for proto linting, buf.gen.yaml for code generation
- [x] Full test coverage for all packages (artifacts, blob, server)

**Files created:**
- `blob/blob.go`, `blob/blob_test.go`
- `artifacts/artifact.go`, `artifacts/citation.go`, `artifacts/publisher.go`, `artifacts/snapshot.go`
- `artifacts/metadata.go`, `artifacts/tagcat.go`, `artifacts/yaml.go`, `artifacts/artifacts_test.go`
- `proto/exo/v1/common.proto`, `proto/exo/v1/artifacts.proto`
- `proto/buf.yaml`, `proto/buf.gen.yaml`
- `proto/exo/v1/*.pb.go` (generated)
- `server/server.go`, `server/server_test.go`
