-# Agent Context Hints
+# AnthoLume - Agent Context
 
-## Current Status
+## Migration Context
-Currently mid migration from go templates (`./templates`) to React App (`./frontend`)
+Updating Go templates (rendered HTML) → React app using V1 API (OpenAPI spec)
 
-## Architecture Context
+## Critical Rules
-- **Backend**: Go with Gin router (legacy), SQLC for database queries, currently migrating to V1 API (oapi-codegen)
-- **Frontend**: React with Vite, currently migrating from Go templates (using the V1 API)
-- **API**: OpenAPI 3.0 spec, generates Go server (oapi-codegen) and TS client (orval)
 
-## Frontend Linting
+### Database Access
-The frontend uses ESLint and Prettier for code quality and formatting.
+- **NEVER write ad-hoc SQL** - Only use SQLC queries from `database/query.sql`
+- Migrate V1 API by mirroring legacy implementation in `api/app-admin-routes.go` and `api/app-routes.go`
 
-### Running Linting
+### Migration Workflow
-- **Check linting**: `cd frontend && bun run lint`
+1. Check legacy implementation for business logic
-- **Fix linting issues**: `cd frontend && bun run lint:fix`
+2. Copy pattern but adapt to use `s.db.Queries.*` instead of `api.db.Queries.*`
-- **Check formatting**: `cd frontend && bun run format`
+3. Map legacy response types to V1 API response types
-- **Format files**: `cd frontend && bun run format:fix`
+4. Never create new DB queries
 
-### When to Run Linting
+### Surprises
-Run linting after making any changes to the frontend to ensure code quality and consistency. All new code should pass linting before committing.
+- Templates may show fields the API doesn't return - cross-check with DB query
+- `start_time` is `interface{}` in Go models, needs type assertion in Go
+- Templates use `LOCAL_TIME()` SQL function for timezone-aware display
 
-### Package Management
+## Error Handling
-The frontend uses **bun** for package management. Use:
+Use `fmt.Errorf("message: %w", err)` for wrapping. Do NOT use `github.com/pkg/errors`.
-- `bun install` to install dependencies
-- `bun add <package>` to add a new package
-- `bun remove <package>` to remove a package
-- `bunx <command>` to run CLI binaries locally
 
-## Data Flow (CRITICAL for migrations)
+## Frontend
-1. Database schema → SQL queries (`database/query.sql`, `database/query.sql.go`)
+- **Package manager**: bun (not npm)
-2. SQLC models → API handlers (`api/v1/*.go`)  
+- **Lint**: `cd frontend && bun run lint` (and `lint:fix`)
-3. Go templates show **intended UI** structure (`templates/pages/*.tmpl`)
+- **Format**: `cd frontend && bun run format` (and `format:fix`)
-4. API spec defines actual API contract (`api/v1/openapi.yaml`)
-5. Generated TS client → React components
 
-## When Migrating from Go Templates
+## Regeneration
-- Check template AND database query results (Go templates may show fields API doesn't return)
-- Template columns often map to: document_id, title, author, start_time, duration, start/end_percentage
-- Go template rendering: `{{ template "component/table" }}` with "Columns" and "Keys"
-
-## API Regeneration Commands
 - Go backend: `go generate ./api/v1/generate.go`
 - TS client: `cd frontend && npm run generate:api`
-
-## Frontend Key Files and Directories
-- **Source code**: `frontend/src/`
-- **Configuration**: `frontend/eslint.config.js`, `frontend/.prettierrc`, `frontend/tsconfig.json`
-- **Build output**: `frontend/dist/`
-- **Generated API client**: `frontend/src/generated/`
-
-## Key Files
-- Database queries: `database/query.sql` → SQLc Query shows actual fields returned
-- SQLC models: `database/query.sql.go` → SQLc Generated Go struct definitions
-- Go templates: `templates/pages/*.tmpl` → Legacy UI reference
-- API spec: `api/v1/openapi.yaml` → contract definition
-- Generated TS types: `frontend/src/generated/model/*.ts`
-
-## Common Gotchas
-- API implementation may not map all fields from DB query (check `api/v1/activity.go` mapping)
-- `start_time` is `interface{}` in Go models, needs type assertion
-- Go templates use `LOCAL_TIME()` SQL function for timezone-aware display
-
-## CRITICAL: Migration Implementation Rules
-- **NEVER write ad-hoc SQL queries** - All database access must use existing SQLC queries from `database/query.sql`
-- **Mirror legacy implementation** - Check `api/app-admin-routes.go`, `api/app-routes.go` for existing business logic
-- **Reuse existing functions** - Look for helper functions in `api/utils.go` that handle file operations, metadata, etc.
-- **SQLC query reference** - Check `database/query.sql` for available queries and `database/query.sql.go` for function signatures
-- **When implementing TODOs in v1 API**:
-  1. Find the corresponding function in legacy API (e.g., `api/app-admin-routes.go`)
-  2. Copy the logic pattern but adapt to use `s.db.Queries.*` instead of `api.db.Queries.*`
-  3. Use existing helper functions from `api/utils.go` (make them accessible if needed)
-  4. Map legacy response types to new v1 API response types
-  5. Never create new database queries - use what SQLC already provides
-
-## API Structure
-- **Legacy API**: `api/` directory (e.g., `api/app-admin-routes.go`, `api/app-routes.go`)
-  - Uses Gin router
-  - Renders Go templates
-  - Contains all existing business logic to mirror
-- **V1 API**: `api/v1/` directory (e.g., `api/v1/admin.go`, `api/v1/documents.go`)
-  - Uses oapi-codegen (OpenAPI spec driven)
-  - Returns JSON responses
-  - Currently being migrated from legacy patterns
