feat(go): M6.7 — single-binary embed verification

Add TestEmbedCompleteness and TestStaticAssetsServed in
go/internal/web/assets_test.go. The completeness guard walks the
on-disk templates/ and static/ directories and asserts every file is
present in the corresponding embed.FS, catching forgotten files on
future additions. The static mux test hits /static/css/app.css and all
JS files through the same http.FileServerFS wiring used in server.go,
confirming assets are served from the embedded FS with correct
Content-Type and a 404 for unknown paths.

Standalone binary smoke test passed manually: binary copied to /tmp
(no adjacent templates/ or static/), assets served correctly.

Closes M6.

 # Changelog
 
-## 2026-05-11 22:56 CEST — fix(python): parse Fio 2-digit-year dates + add `make sync-debug` dry-run tool
+## 2026-05-08 15:24 CEST — feat(go): M6.7 — single-binary embed verification
 
-- Fix: `scripts/fio_utils.py` `parse_czech_date` now accepts `DD.MM.YY` / `D.M.YY` in addition to the 4-digit-year variants. Fio's transparent page now mixes both forms in the same response; the 2-digit rows were being silently dropped, which caused `make sync-2026` to miss every recent transfer. Mirrors the Go-side fix from 2026-05-07 (CHANGELOG entry below).
+- Confirmed `embed.FS` wiring is complete: templates parsed via `template.ParseFS(templateFS, ...)`, static assets served via `http.FileServerFS(fs.Sub(staticFS, "static"))`.
-- Added `--dry-run` and `--print-fio-table` flags to `scripts/sync_fio_to_sheets.py`, plus a `make sync-debug [DAYS=N]` Makefile target. Mirrors `make go-sync-debug`: fetches from Fio and dedupes against the sheet, prints `STATUS=NEW/DUP` per transaction, and prints per-row `Dry run: would append …` lines + `would sort by date` instead of touching the sheet.
+- Added `go/internal/web/assets_test.go` with two tests: `TestEmbedCompleteness` (walks disk vs embed.FS to catch forgotten files) and `TestStaticAssetsServed` (hits `/static/css/app.css` and all JS files through the mux, asserts 200 + Content-Type + non-empty body + 404 for unknown paths).
-- Added always-on stderr diagnostics in `scripts/fio_utils.py`: which fetcher was selected (authenticated API vs. transparent-page scraper with `FIO_API_TOKEN`-unset warning), and raw-vs-after-filter transaction counts on both paths — so this class of "scraper drops everything" bug surfaces immediately.
+- Closes M6; single binary confirmed self-contained with no adjacent `templates/` or `static/` required at runtime.
+- Key files: `go/internal/web/assets_test.go` (new).

+# M6.7 — Single-binary embed verification
+
+## Context
+
+M6.7 is the final task in M6 (Go-native HTML frontend). Per the
+[progress tracker](2026-05-03-2349-go-backend-rewrite-progress.md): "Wire
+`embed.FS` into handlers; verify single-binary deployment includes all
+assets."
+
+The wiring is **already in place** from M6.1 onward:
+
+- [go/internal/web/assets.go](../../go/internal/web/assets.go) declares
+  `//go:embed templates` → `templateFS` and `//go:embed static` → `staticFS`.
+- [go/internal/web/render.go:66](../../go/internal/web/render.go#L66)
+  parses every page template via `template.New(...).ParseFS(templateFS, ...)`.
+- [go/internal/web/server.go:48-68](../../go/internal/web/server.go#L48-L68)
+  serves `/static/*` via `http.FileServerFS(fs.Sub(staticFS, "static"))`.
+- [go/build/Dockerfile](../../go/build/Dockerfile) copies only the compiled
+  binary into the `alpine:3` runtime image — no `templates/` or `static/`
+  directory ever lands beside it.
+
+What is missing is **proof** the embed is complete and stays complete:
+
+1. Nothing fails the build/test if a contributor adds a new file under
+   `internal/web/templates/` or `internal/web/static/` that isn't matched
+   by an `//go:embed` glob (or, more realistically, adds a sibling
+   directory like `static/img/` and the glob still picks it up — but a
+   typo'd directive would silently drop it).
+2. No automated test exercises the `/static/*` route against the embedded
+   FS — current tests in
+   [html_handler_test.go](../../go/internal/web/html_handler_test.go)
+   render templates (which proves `templateFS` is good) but never hit a
+   static URL through the mux.
+3. The "single binary, no working-dir assets" property is undocumented —
+   if it ever broke, no one would notice until the Docker image started
+   500'ing in prod.
+
+The intended outcome: a small test file plus a documented manual
+verification step, after which M6.7 can be ticked and M6 closed.
+
+## Plan
+
+### 1. Add `go/internal/web/assets_test.go`
+
+One new file, two tests, no production code changes.
+
+**Test A — embed completeness regression guard.** Walks the on-disk
+`templates/` and `static/` directories and asserts every regular file is
+also present in the corresponding embedded FS. Catches:
+
+- A new template added without updating the `//go:embed` directive
+  (current globs are `templates` and `static` — recursive by default for
+  directories, so this is a low-probability regression, but the test
+  doubles as living documentation of the contract).
+- A typo in the directive (e.g. someone renames `static` → `assets` in
+  one place but not the other).
+
+Implementation sketch:
+
+```go
+func TestEmbedCompleteness(t *testing.T) {
+    cases := []struct {
+        name   string
+        diskFS fs.FS         // os.DirFS("templates") / os.DirFS("static")
+        embed  fs.FS         // exported helper or via internal test in package web
+        root   string
+    }{...}
+    for _, tc := range cases {
+        _ = fs.WalkDir(tc.diskFS, ".", func(path string, d fs.DirEntry, err error) error {
+            if err != nil || d.IsDir() { return err }
+            embPath := tc.root + "/" + path
+            if _, err := fs.Stat(tc.embed, embPath); err != nil {
+                t.Errorf("file %q on disk but missing in embed.FS: %v", embPath, err)
+            }
+            return nil
+        })
+    }
+}
+```
+
+Because `templateFS` and `staticFS` are unexported package vars, this
+test lives in `package web` (not `web_test`) — sibling to
+[assets.go](../../go/internal/web/assets.go). All the existing handler
+tests are in `package web_test`; that's fine, this one is internal.
+
+**Test B — `/static/*` end-to-end via the mux.** Builds an `http.ServeMux`
+with the same wiring as
+[server.go:68](../../go/internal/web/server.go#L68), fires httptest
+requests, asserts:
+
+- `GET /static/css/app.css` → 200, `Content-Type: text/css; charset=utf-8`,
+  body contains a known string from app.css (e.g. a CSS selector).
+- `GET /static/js/member-detail.js` → 200, `Content-Type` starts with
+  `text/javascript` or `application/javascript`, body non-empty.
+- `GET /static/js/payment-qr.js` → 200, body non-empty.
+- `GET /static/css/missing.css` → 404 (sanity: the file server actually
+  rejects unknown paths instead of returning some default).
+
+Rather than duplicate the mux assembly, factor a tiny helper (or test the
+existing mux). The cleanest move: extract `staticHandler()` from
+[server.go:48-50,68](../../go/internal/web/server.go#L48-L68) into a small
+exported-from-package function or just `staticFS` / `fs.Sub` helper, and
+have the test call it. Smallest delta: keep production code unchanged and
+replicate the two-line wiring inside the test file (acceptable — it's
+two lines and the test exists precisely to lock that contract).
+
+### 2. Manual / one-shot verification (no code; documented in plan only)
+
+Run once locally and tick M6.7. Command transcript:
+
+```bash
+make go-build                  # → ./bin/fuj
+cp bin/fuj /tmp/fuj-standalone
+cd /tmp                        # working dir has no templates/ or static/
+./fuj-standalone server &
+SERVER_PID=$!
+sleep 1
+curl -sf http://localhost:8080/adults | grep -q "Adults Dashboard"
+curl -sf http://localhost:8080/juniors | grep -q "Juniors"
+curl -sf http://localhost:8080/payments | grep -q "Payments Ledger"
+curl -sf -o /tmp/app.css http://localhost:8080/static/css/app.css \
+  && test -s /tmp/app.css
+curl -sf -o /tmp/qr.js http://localhost:8080/static/js/payment-qr.js \
+  && test -s /tmp/qr.js
+kill $SERVER_PID
+```
+
+`fuj server` will fail to talk to Sheets without credentials, so the
+`/adults` etc. pages will render with the `Error` field set — that's
+fine; the assertion is that the **template + static asset pipeline** is
+self-contained, not that data loads. Each curl above only checks for
+markup present in every render path (header text and stylesheet body).
+
+### 3. Tracker + changelog
+
+- Tick `M6.7` in
+  [docs/plans/2026-05-03-2349-go-backend-rewrite-progress.md:120](2026-05-03-2349-go-backend-rewrite-progress.md#L120),
+  append the merge SHA on the line.
+- Mark "Last updated" date and bump milestone status: M6 complete, next is
+  M7.
+- Append a `CHANGELOG.md` entry per CLAUDE.md convention (`date "+%Y-%m-%d %H:%M %Z"`).
+
+## Files touched
+
+| File | Change |
+| --- | --- |
+| [go/internal/web/assets_test.go](../../go/internal/web/assets_test.go) | **new** — two tests (embed completeness + `/static/*` mux) |
+| [docs/plans/2026-05-03-2349-go-backend-rewrite-progress.md](2026-05-03-2349-go-backend-rewrite-progress.md) | tick M6.7, bump "last updated" |
+| [CHANGELOG.md](../../CHANGELOG.md) | new top entry |
+
+No production source files change. (If extracting the static handler
+reads cleaner, a 4-line refactor in
+[server.go](../../go/internal/web/server.go) is acceptable but optional.)
+
+## Branch + MR
+
+Per project convention this is a feature, so:
+
+```bash
+git checkout -b feat/go-m6-7-embed-verify
+# … commits …
+git push -u origin feat/go-m6-7-embed-verify
+tea pr create --title "feat(go): M6.7 — single-binary embed verification" \
+  --description "<short body referencing M6.7>" --base main \
+  --head feat/go-m6-7-embed-verify
+```
+
+## Verification
+
+After implementation:
+
+1. `make go-test` → green (new `TestEmbedCompleteness` and `TestStaticAssetsServed` pass).
+2. `make go-lint` → clean.
+3. Run the manual transcript in §2 above — all curls succeed, no
+   "template not found" or 404 on static assets.
+4. `make go-build && docker build -f go/build/Dockerfile -t fuj-go:m6-7 go/` →
+   succeeds; `docker run --rm -p 8080:8080 fuj-go:m6-7` serves `/adults`
+   with stylesheet attached (visual smoke test in browser).
+
+## Out of scope
+
+- Re-architecting how templates are parsed or served.
+- Compressing / fingerprinting static assets (a separate concern).
+- Live integration test with real Sheets data — covered later in M7.
