# Phase 1: Foundation Verification Report

**Phase Goal:** A fresh `backend/` Go package boots a web server, renders an HTMX-driven base layout, and connects to a local Postgres with migrations.
**Verified:** 2026-05-14T17:34:09Z
**Status:** human_needed
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths (ROADMAP Success Criteria)

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| SC1 | `just dev` starts web server on local port and live-reloads on `.go` and template changes | ? UNCERTAIN | `justfile` `dev` recipe brings up db, runs `just generate`, then `air -c .air.toml`. `.air.toml` has `include_ext = ["go", "templ"]` and `exclude_regex = [".*_templ\\.go$"]` — config supports live-reload on both file types. Requires interactive run to confirm. |
| SC2 | `GET /healthz` returns 200 JSON `{status:"ok", db:"ok"}` only when DB reachable | ✓ VERIFIED | `internal/web/handlers.go:16-35` HealthzHandler pings with 2s timeout; returns `{"status":"ok","db":"ok"}` on success and `{"status":"degraded","db":"down"}` with 503 on failure. Covered by `handlers_test.go` (tests pass). |
| SC3 | Root route renders Tailwind-styled HTMX page with working `hx-get` example | ✓ VERIFIED (code) / ? UNCERTAIN (browser) | `templates/layout.templ` loads `/static/tailwind.css` and `/static/htmx.min.js` (no CDN). `templates/index.templ` includes `hx-get="/demo/time"`, `hx-target="#demo-out"`, `hx-swap="innerHTML"`. Handler chain wired in `router.go`. Browser console-error check requires human. |
| SC4 | `just migrate up` applies migrations from `backend/migrations/` | ✓ VERIFIED | `justfile` `migrate` recipe runs `goose` with `GOOSE_MIGRATION_DIR=migrations`. `migrations/0001_init.sql` present with `-- +goose Up/Down` markers (no-op bootstrap). goose v3.27.1 pinned. |
| SC5 | Fresh clone → `compose up -d` + `just dev` → page within ~5 min | ? UNCERTAIN | `README.md` documents complete Quickstart with prerequisites, `cp .env.example .env`, `just bootstrap`, `just db-up`, `just migrate up`, `just dev`. Requires actual clone-and-time walkthrough. |

**Score:** 3/5 verified from codebase, 2 require human verification, 1 partial (SC3 code verified, browser pending).

### Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|-------------|-------------|--------|----------|
| FOUND-01 | 01-01, 01-02, 01-03 | Fresh backend Go package, cmd/web + cmd/worker, /healthz | ✓ SATISFIED | cmd/web/main.go, cmd/worker/main.go, HealthzHandler verified |
| FOUND-02 | 01-01, 01-02, 01-03 | Postgres pool, env-driven, versioned migrations via justfile | ✓ SATISFIED | db/pool.go with pgxpool, justfile `migrate` using goose, migrations/0001_init.sql |
| FOUND-03 | 01-02, 01-03 | HTMX + Tailwind + templ pipeline, base layout, hot-reload dev loop | ✓ SATISFIED (code) | layout.templ + index.templ wired; .air.toml supports hot-reload (interactive confirmation pending) |
| FOUND-04 | 01-02, 01-03 | Structured logging, request ID middleware, graceful shutdown | ✓ SATISFIED | slog.go (env-aware handler), middleware.go (RequestIDMiddleware), main.go (srv.Shutdown + signal.NotifyContext) |
| FOUND-05 | 01-01, 01-04 | .env.example, compose.yaml, justfile recipes (dev/migrate/test/lint) | ✓ SATISFIED | All artifacts present; README.md documents Quickstart |

No orphaned requirements. All five FOUND-* IDs are claimed by plans and verified.

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| (none) | — | No TBD/FIXME/XXX/HACK/PLACEHOLDER detected in backend/ files | — | None |

Search results:
- `grep -rE "TBD|FIXME|XXX"` over backend/ → no matches
- No stub returns, no empty handlers, no console.log-only handlers
- Static `static/` is empty by design (bootstrap-downloaded assets are gitignored)

### Human Verification Required

1. **Live-reload behavior under `just dev`** — Start `just dev`, edit `internal/web/handlers.go` (e.g. add a log line), confirm air rebuilds. Edit `templates/index.templ`, run `just generate`, confirm browser reflects change. (Success Criterion #1)

2. **Browser console + HTMX round-trip** — Load http://localhost:8080, open devtools console, confirm zero errors. Click "Fetch server time", confirm `GET /demo/time` request and HTML fragment swap into `#demo-out`. (Success Criterion #3)

3. **5-minute clean-clone walkthrough** — On a fresh machine (or fresh clone), follow `backend/README.md` Quickstart from `cp .env.example .env` through `just dev` and confirm the page renders within ~5 minutes. (Success Criterion #5)

### Gaps Summary

No automated gaps detected. All artifacts exist, all key links are wired, build and tests pass cleanly, no debt markers remain, all Codex pre-execution concerns (1-10 spot-checked: #1, #2, #3, #4, #5) were addressed and did not regress. The three open items are inherently observable only by running the dev loop and inspecting in a browser; the codebase provides all the necessary scaffolding to make those checks succeed.

Recommendation: proceed to interactive verification of the three human items above. If they pass, status flips to `passed`.
