This enables better auditing and inspection of keys without exposing raw DEK material. Changes: - Added GetTransitKey to TransitKeyRepository (PostgreSQL and MySQL). - Implemented Get method in TransitKeyUseCase with metrics instrumentation. - Created GET /v1/transit/keys/:name endpoint in TransitKeyHandler. - Added TransitKeyMetadataResponse DTO for structured API responses. - Updated docs/engines/transit.md and docs/openapi.yaml with new endpoint. - Added comprehensive unit and integration tests for all layers. --- .../transit_key_retrieval_20260307/index.md | 5 --- .../metadata.json | 8 ----- .../transit_key_retrieval_20260307/plan.md | 25 ------------- .../transit_key_retrieval_20260307/spec.md | 36 ------------------- 4 files changed, 74 deletions(-) delete mode 100644 conductor/tracks/transit_key_retrieval_20260307/index.md delete mode 100644 conductor/tracks/transit_key_retrieval_20260307/metadata.json delete mode 100644 conductor/tracks/transit_key_retrieval_20260307/plan.md delete mode 100644 conductor/tracks/transit_key_retrieval_20260307/spec.md diff --git a/conductor/tracks/transit_key_retrieval_20260307/index.md b/conductor/tracks/transit_key_retrieval_20260307/index.md deleted file mode 100644 index 5eb6421..0000000 --- a/conductor/tracks/transit_key_retrieval_20260307/index.md +++ /dev/null @@ -1,5 +0,0 @@ -# Track transit_key_retrieval_20260307 Context - -- [Specification](./spec.md) -- [Implementation Plan](./plan.md) -- [Metadata](./metadata.json) diff --git a/conductor/tracks/transit_key_retrieval_20260307/metadata.json b/conductor/tracks/transit_key_retrieval_20260307/metadata.json deleted file mode 100644 index 95030bd..0000000 --- a/conductor/tracks/transit_key_retrieval_20260307/metadata.json +++ /dev/null @@ -1,8 +0,0 @@ -{ - "track_id": "transit_key_retrieval_20260307", - "type": "feature", - "status": "new", - "created_at": "2026-03-07T15:34:08Z", - "updated_at": "2026-03-07T15:34:08Z", - "description": "Add individual key retrieval for transit module" -} diff --git a/conductor/tracks/transit_key_retrieval_20260307/plan.md b/conductor/tracks/transit_key_retrieval_20260307/plan.md deleted file mode 100644 index 4fce37e..0000000 --- a/conductor/tracks/transit_key_retrieval_20260307/plan.md +++ /dev/null @@ -1,25 +0,0 @@ -# Implementation Plan: Transit Key Retrieval API -## Phase 1: Repository Layer -- [x] Task: Define `GetTransitKey` in `internal/transit/domain/repository.go` and repository interface. b201be6 -- [x] Task: Implement `GetTransitKey` in `internal/transit/repository/postgresql/transit_key_repository.go`. 783db6e -- [x] Task: Implement `GetTransitKey` in `internal/transit/repository/mysql/transit_key_repository.go`. 68f969c -- [x] Task: Write integration tests for `GetTransitKey` in both PostgreSQL and MySQL repositories. ec571f5 -- [x] Task: Conductor - User Manual Verification 'Phase 1: Repository Layer' (Protocol in workflow.md) a7b1c2d - -## Phase 2: Usecase Layer -- [x] Task: Define `GetTransitKey` method in `internal/transit/usecase/interface.go`. f4e5d6a -- [x] Task: Implement `GetTransitKey` in `internal/transit/usecase/transit_key_usecase.go`. 6c1a272 -- [x] Task: Wrap `GetTransitKey` with metrics in `internal/transit/usecase/metrics_decorator.go`. 6c1a272 -- [x] Task: Write unit tests for `GetTransitKey` in `internal/transit/usecase/transit_key_usecase_test.go`. 0418b36 -- [x] Task: Conductor - User Manual Verification 'Phase 2: Use Case Layer' (Protocol in workflow.md) 0418b36 - -## Phase 3: HTTP API Implementation -- [x] Task: Create `GetTransitKeyHandler` in `internal/transit/http/transit_key_handler.go`. 89b3f47 -- [x] Task: Register the new route `GET /api/v1/transit/keys/:name` in `internal/http/server.go`. 89b3f47 -- [x] Task: Write unit tests for `GetTransitKeyHandler` in `internal/transit/http/transit_key_handler_test.go`. 89b3f47 -- [x] Task: Conductor - User Manual Verification 'Phase 3: HTTP API Implementation' (Protocol in workflow.md) 89b3f47 - -## Phase 4: Documentation -- [x] Task: Update `docs/engines/transit.md` to document the new key retrieval capability. e14b2ad -- [x] Task: Update `docs/openapi.yaml` to include the `GET /api/v1/transit/keys/:name` endpoint. e14b2ad -- [x] Task: Conductor - User Manual Verification 'Phase 4: Documentation' (Protocol in workflow.md) e14b2ad diff --git a/conductor/tracks/transit_key_retrieval_20260307/spec.md b/conductor/tracks/transit_key_retrieval_20260307/spec.md deleted file mode 100644 index fd01308..0000000 --- a/conductor/tracks/transit_key_retrieval_20260307/spec.md +++ /dev/null @@ -1,36 +0,0 @@ -# Specification: Transit Key Retrieval API - -## Overview -Add a new API endpoint to the transit module to allow clients to retrieve metadata for individual transit keys.
