# Agent

Name: Agent 01 - Foundation

Stage: Foundation

Date: 2026-04-13

## Scope

Set up the initial runnable Go application skeleton for the update server.

Completed in this stage:

- initialized the Go module;
- added the server entrypoint and graceful app bootstrap;
- implemented environment-based config loading with sensible local defaults;
- wired the base `chi` router, middleware stack, and route groups;
- added a JSON health endpoint;
- added template bootstrapping and the first server-rendered HTML pages;
- added base static assets and a `Justfile` for local run/build/test tasks;
- created the `migrations` directory placeholder for the next stage.

## Files Changed

- `/Users/delete/projects/update_server/.gitignore`
- `/Users/delete/projects/update_server/go.mod`
- `/Users/delete/projects/update_server/go.sum`
- `/Users/delete/projects/update_server/Justfile`
- `/Users/delete/projects/update_server/cmd/server/main.go`
- `/Users/delete/projects/update_server/internal/app/app.go`
- `/Users/delete/projects/update_server/internal/config/config.go`
- `/Users/delete/projects/update_server/internal/http/router.go`
- `/Users/delete/projects/update_server/internal/http/middleware.go`
- `/Users/delete/projects/update_server/internal/http/handlers.go`
- `/Users/delete/projects/update_server/internal/http/render.go`
- `/Users/delete/projects/update_server/internal/http/response.go`
- `/Users/delete/projects/update_server/web/templates/layouts/base.gohtml`
- `/Users/delete/projects/update_server/web/templates/pages/home.gohtml`
- `/Users/delete/projects/update_server/web/templates/pages/admin.gohtml`
- `/Users/delete/projects/update_server/web/static/app.css`
- `/Users/delete/projects/update_server/migrations/README.md`

## Database Changes

- no schema or migration files were added in this stage;
- created `/Users/delete/projects/update_server/migrations` with a placeholder README so Agent 02 can own the first migration set cleanly.

## API Or Route Changes

- added `GET /healthz` returning JSON status;
- added `GET /` as the foundation landing page;
- added `GET /admin` as the reserved admin route group entry;
- added `GET /api/v1` as the reserved versioned API route group entry;
- added static asset serving under `/static/*`.

## Commands And Tests Run

- `gofmt -w ./cmd ./internal` - completed successfully;
- `go mod tidy` - completed successfully after running with normal network/cache access;
- `go test ./...` - completed successfully;
- `go build -o /tmp/update-server ./cmd/server` - completed successfully;
- started `/tmp/update-server` on `127.0.0.1:18080` and verified `curl http://127.0.0.1:18080/healthz` returned `200 OK` JSON.

## Known Limitations

- no database connection or migration runner exists yet;
- no authentication, sessions, uploads, or business modules are implemented yet;
- template loading currently reads from the filesystem path configured by `TEMPLATES_DIR`;
- a local `data-dev/` directory is created on startup and is intentionally ignored via `.gitignore`.

## Recommended Next Step

Agent 02 should implement the SQLite foundation next: add the migration tool flow, create the initial schema files for the spec tables, and introduce the database connection/repository layer without changing the existing app bootstrap, config contract, or route-group structure.

## Notes For Validator

- there were no prior stage handoff or validation reports yet; only the directory README placeholders existed;
- pay attention to whether the app boots from the repo root, whether `/healthz` responds, and whether the route groups remain ready for later auth and feature modules.
