 # Changelog
 
+## 2026-06-12 19:32 CEST — feat(ci): gitops image-update PR workflow
+
+- Added `.gitea/workflows/gitops-update.yaml`: after each successful Go image build, `uh-cli gitops deployment update` opens a PR in `kacerr/home-kubernetes` bumping the `fuj-management` Deployment (namespace `fuj`) to the new image tag.
+- Supports `workflow_run` auto-trigger and `workflow_dispatch` with `dry_run` / `uh_cli_version` inputs.
+- Requires `GITOPS_TOKEN` repo secret (Gitea PAT with write+PR access to `home-kubernetes`).
+
+## 2026-05-24 21:58 CEST — feat(fees): update adult monthly rates for 2026-05 through 2026-08
+
+- 2026-05: 700 → 450 CZK; 2026-06/07/08: 600 CZK (new months added).
+- Mirrored in both `scripts/attendance.py` and `go/internal/domain/fees/fees.go`.
+
+## 2026-05-24 21:42 CEST — feat: multi-account Fio sync + switch QR default to 2502035405/2010
+
+- Added second bank account `2502035405/2010` (IBAN `CZ0820100000002502035405`) to sync.
+- Both accounts are fetched on every sync; dedup by existing sync_id keeps the payments sheet clean.
+- QR codes now default to the new account (`CZ0820100000002502035405`).
+- Go: `config.go` gains hardcoded `Accounts`/`LoadedAccount` slice; `Config.BankAccount` renamed to `Config.QRAccount`; `FioAPIToken` removed (tokens are per-account via `FIO_API_TOKEN_NEW` / `FIO_API_TOKEN_OLD`).
+- Go: `SyncToSheets` now accepts `[]fio.Client`; new `TestSyncToSheets_MultiAccount` test.
+- Python: `config.py` gains `ACCOUNTS` / `LOADED_ACCOUNTS`; `fio_utils.py` adds `fetch_transactions_for` and `fetch_transactions_all`; `sync_fio_to_sheets.py` uses `fetch_transactions_all`.
+- Key files: `go/internal/config/config.go`, `go/internal/services/banksync/sync.go`, `go/cmd/fuj/main.go`, `scripts/config.py`, `scripts/fio_utils.py`, `scripts/sync_fio_to_sheets.py`.

@@ -14,6 +35,12 @@
 - 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).
 - 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 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.
+## 2026-05-08 15:24 CEST — feat(go): M6.7 — single-binary embed verification
+
+- Confirmed `embed.FS` wiring is complete: templates parsed via `template.ParseFS(templateFS, ...)`, static assets served via `http.FileServerFS(fs.Sub(staticFS, "static"))`.
+- 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).
+- 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.

+# Multi-account Fio sync + switch QR target to 2502035405/2010
+
+## Context
+
+The club is opening a second Fio transparent account, **`2502035405/2010`** (IBAN
+`CZ??...0000002502035405`). Going forward:
+
+- **Sync** must pull transactions from **both** accounts into the existing
+  payments sheet — the old `2800359168/2010` stays active so historical fees
+  paid to it still reconcile.
+- **QR codes** generated by `/qr` should default to the **new** account
+  (`2502035405/2010`), so new payers send money there.
+
+The payments sheet schema and `sync_id` hash stay **unchanged** — no
+"Source Account" column, no migration, no risk of re-appending historical rows.
+Bank-ID uniqueness from Fio plus the existing hash inputs are good enough to
+dedupe across two transparent accounts in practice.
+
+Implementation order: Go first, then port to Python. Both apps use the same
+`PaymentsSheetID`, so once Go writes from two accounts the Python code only
+needs to do the same when invoked.
+
+### Decisions locked in with the user
+- **Config style:** hardcoded list of accounts in `config.go` / `config.py`
+  (sheet IDs are already hardcoded; tokens stay env-driven).
+- **Source tagging:** no schema change, `sync_id` formula unchanged.
+- **Old account:** kept syncing in parallel; only QR target changes.
+
+---
+
+## Go implementation
+
+### 1. Config — hardcoded `Accounts` list, derived `QRAccount`
+
+[go/internal/config/config.go](../../go/internal/config/config.go)
+
+- Replace scalar `BankAccount` + `FioAPIToken` with a hardcoded slice and a
+  primary pointer. Tokens stay env-driven via per-account env names.
+
+  ```go
+  // Account describes one Fio bank account we sync from.
+  type Account struct {
+      IBAN     string // e.g. "CZ0820100000002502035405"
+      AcctNum  string // bare account number, e.g. "2502035405"
+      TokenEnv string // env var name holding the Fio API token (empty token => transparent scraper path)
+      Primary  bool   // true for the QR-code default account
+  }
+
+  var Accounts = []Account{
+      {IBAN: "CZ0820100000002502035405", AcctNum: "2502035405", TokenEnv: "FIO_API_TOKEN_NEW", Primary: true},
+      {IBAN: "CZ8520100000002800359168", AcctNum: "2800359168", TokenEnv: "FIO_API_TOKEN_OLD"},
+  }
+  ```
+  Compute the **real** IBAN check digit for `2502035405` once and bake it in
+  (replace the `85` placeholder above). The same `IBANAccountNum` helper at
+  [config.go:66](../../go/internal/config/config.go#L66) keeps producing
+  `AcctNum`, but having it on the struct avoids re-parsing at every call site.
+
+- `Config` struct:
+  - Drop `BankAccount` and `FioAPIToken` fields.
+  - Add `QRAccount string` (the IBAN of `Accounts[i].Primary == true`).
+  - Add `LoadedAccounts []LoadedAccount` where each entry pairs an `Account`
+    with the token resolved from `os.Getenv(account.TokenEnv)`.
+- `Load()` reads each `TokenEnv` and stores tokens with the account. Logs a
+  warning (info-level) if no token is set — that's the transparent-scraper
+  path, which is fine.
+
+### 2. Sync loop — one `fio.Client` per account, single dedup pass
+
+[go/internal/services/banksync/sync.go](../../go/internal/services/banksync/sync.go)
+
+Change `SyncToSheets` to accept a slice of clients instead of one:
+
+```go
+func SyncToSheets(
+    ctx context.Context,
+    spreadsheetID string,
+    fioClients []fio.Client, // was: fioClient fio.Client
+    sh sheetsWriter,
+    opts SyncOpts,
+) (int, error)
+```
+
+Inside:
+
+- Keep steps 1 (read existing IDs) and 2 (date window) as-is.
+- Step 3 (fetch) becomes a loop: call `FetchTransactions` on each client; tag
+  each `fio.Transaction` with the account it came from for logging only
+  (don't write it to the sheet). Concatenate into one slice `txns`.
+- Steps 4a–4c (sync_id calc, debug table, row build, dedup) are unchanged —
+  the combined `txns` slice flows through the same code path. Existing
+  `sync_id` collisions across accounts are dropped silently, which is the
+  desired dedup behaviour.
+- `printFioTable` (dry-run debug) should print an extra column showing the
+  source account so per-account fetches are visible — small change in
+  [fio_table.go](../../go/internal/services/banksync/fio_table.go).
+
+Logger output: log fetched count per account and the total combined count.
+
+### 3. Call sites — build clients from the config list
+
+Both entry points construct `[]fio.Client`, one per `LoadedAccount`:
+
+- [go/cmd/fuj/main.go:91](../../go/cmd/fuj/main.go#L91) — server `BankSync` action.
+- [go/cmd/fuj/main.go:200](../../go/cmd/fuj/main.go#L200) — `fuj sync` CLI.
+
+Helper to add somewhere in `cmd/fuj/main.go` or a new
+`internal/services/banksync/clients.go`:
+
+```go
+func clientsFromConfig(cfg config.Config) []fio.Client {
+    out := make([]fio.Client, 0, len(cfg.LoadedAccounts))
+    for _, a := range cfg.LoadedAccounts {
+        out = append(out, fio.New(a.Token, a.AcctNum, nil))
+    }
+    return out
+}
+```
+
+The existing factory at
+[go/internal/io/fio/client.go:35](../../go/internal/io/fio/client.go#L35)
+already routes per-account between the API path and the transparent scraper
+based on whether the token is empty — no change there.
+
+### 4. QR endpoint — default to `QRAccount`
+
+[go/internal/web/html_handler.go:129](../../go/internal/web/html_handler.go#L129)
+and [html_handler.go:135](../../go/internal/web/html_handler.go#L135):
+swap `h.apiHandler.Config.BankAccount` → `h.apiHandler.Config.QRAccount`.
+
+API DTOs that surface the payment account in JSON:
+[build_adults.go:141](../../go/internal/web/api/build_adults.go#L141) and
+[build_juniors.go:137](../../go/internal/web/api/build_juniors.go#L137) — same
+swap.
+
+The fields on the API structs at
+[adults.go:40](../../go/internal/web/api/adults.go#L40) and
+[juniors.go:39](../../go/internal/web/api/juniors.go#L39) keep their JSON
+names so the Python parity binary doesn't see a schema diff.
+
+### 5. Tests
+
+- **New** [go/internal/services/banksync/sync_test.go](../../go/internal/services/banksync/sync_test.go):
+  add a test `TestSyncToSheets_MultiAccount` that wires up two fake
+  `fio.Client`s (via the existing
+  [fake.go](../../go/internal/io/fio/fake.go)), one returning a txn unique to
+  it and one returning a txn that duplicates an existing sync_id. Assert:
+  rows from both accounts get appended, the duplicate is dropped.
+- **Update** [go/internal/web/html_handler_test.go:207](../../go/internal/web/html_handler_test.go#L207)
+  `TestServeQR` and [qr_test.go](../../go/internal/web/qr_test.go)
+  `TestQRBuildSPD` — expected SPD strings now contain the new IBAN by default.
+- **Update** any config tests asserting `cfg.BankAccount` directly to use
+  `cfg.QRAccount` and the new `LoadedAccounts` slice. (Grep for `BankAccount`
+  under `go/` after the rename.)
+- Existing fio parser tests
+  ([fio_test.go](../../go/internal/io/fio/fio_test.go)) and sync_id test
+  ([synch_test.go](../../go/internal/domain/synch/synch_test.go)) need no
+  changes — they don't know about the account list.
+
+### 6. Verification (Go)
+
+1. `cd go && go build ./... && go test ./...` — all green.
+2. `FIO_API_TOKEN_NEW="" FIO_API_TOKEN_OLD="" ./build/fuj sync --dry-run --print-fio-table --days 7`
+   — see fetched transactions from **both** accounts, with NEW/DUP status,
+   without writing.
+3. `./build/fuj server` then visit
+   `http://localhost:8080/qr?amount=700&message=test` — QR payload SPD must
+   contain the new IBAN `CZ??...2502035405`.
+4. Real sync once dry-run looks right: `./build/fuj sync --days 30` — confirm
+   in the Google sheet that rows from the old account still appear and no
+   duplicates are written.
+
+---
+
+## Python port (after Go is merged)
+
+The Python app uses the same payments sheet and the same column schema, so
+the port mirrors the Go change one-for-one. Goal: one round-trip of
+`make sync-2026` pulls from both accounts.
+
+### 1. `scripts/config.py`
+
+- Replace the scalar `BANK_ACCOUNT` constant at
+  [scripts/config.py:25](../../scripts/config.py#L25) with a hardcoded list
+  plus a derived primary:
+
+  ```python
+  ACCOUNTS = [
+      {"iban": "CZ0820100000002502035405", "acct_num": "2502035405", "token_env": "FIO_API_TOKEN_NEW", "primary": True},
+      {"iban": "CZ8520100000002800359168", "acct_num": "2800359168", "token_env": "FIO_API_TOKEN_OLD", "primary": False},
+  ]
+  BANK_ACCOUNT = next(a["iban"] for a in ACCOUNTS if a["primary"])  # QR / template default
+  ```
+  Use the real check-digit IBAN for `2502035405` (the same one baked into Go).
+
+- Resolve tokens at module load time with `os.environ.get(token_env, "")` and
+  stash them on a parallel `LOADED_ACCOUNTS` list (or attach to the dicts) so
+  other modules don't all re-read env.
+
+### 2. `scripts/fio_utils.py`
+
+- [fio_utils.py:106](../../scripts/fio_utils.py#L106) and
+  [fio_utils.py:219](../../scripts/fio_utils.py#L219): drop the hardcoded
+  `"2800359168"` default for `account_id`. Make it a required argument.
+- `fetch_transactions(date_from, date_to, *, account)` — change signature to
+  take one account dict, return that account's transactions. Internally still
+  routes via `FIO_API_TOKEN` if the account dict has a token, otherwise the
+  transparent scraper at
+  [fio_utils.py:105](../../scripts/fio_utils.py#L105).
+- Add `fetch_transactions_all(date_from, date_to, accounts=None)` that loops
+  over `accounts` (default `config.LOADED_ACCOUNTS`), calls the per-account
+  fetch, concatenates results. Logs per-account counts.
+
+### 3. `scripts/sync_fio_to_sheets.py`
+
+- Where it currently calls `fio_utils.fetch_transactions(...)`, switch to
+  `fio_utils.fetch_transactions_all(...)`. The dedup at
+  [sync_fio_to_sheets.py:62](../../scripts/sync_fio_to_sheets.py#L62) and
+  append at
+  [sync_fio_to_sheets.py:248](../../scripts/sync_fio_to_sheets.py#L248) need
+  no changes — same as in Go, the combined list flows through unchanged.
+
+### 4. `app.py` (QR + template defaults)
+
+- `/qr` at [app.py:321](../../app.py#L321) already reads `BANK_ACCOUNT` from
+  config; since the config default now points at the new IBAN, this is a
+  zero-line change in `app.py`.
+- The `BANK_ACCOUNT` passed into templates at
+  [app.py:180](../../app.py#L180), [app.py:204](../../app.py#L204),
+  [app.py:255](../../app.py#L255), [app.py:291](../../app.py#L291) likewise
+  picks up the new default automatically.
+
+### 5. Tests
+
+The Python suite has **no** existing coverage of `fio_utils`,
+`sync_fio_to_sheets`, or `/qr`. Don't add new tests — keep the port minimal
+and rely on the Go test suite + manual verification for correctness.
+
+### 6. Verification (Python)
+
+1. `make test` — existing suite stays green (the config refactor must not
+   break [tests/test_app.py](../../tests/test_app.py)).
+2. `make sync-2026` against the real sheet, dry-run first if the script
+   supports it, then real run — confirm rows from both accounts arrive.
+3. `make web-debug` → open `/qr?amount=700&message=test` → QR payload SPD
+   contains the new IBAN.
+
+---
+
+## Branching
+
+Per `CLAUDE.md`: this is a feature, so `feat/multi-account-bank-sync` off
+`main`. Two MRs:
+
+1. `feat/multi-account-bank-sync-go` — Go change end-to-end.
+2. `feat/multi-account-bank-sync-py` — Python port, opened after (1) is
+   merged.
+
+Each MR opened via `tea pr create`. CHANGELOG.md entry per MR.
+
+## Out of scope
+
+- No sheet schema migration.
+- No change to `sync_id` hash inputs at
+  [domain/synch/synch.go:14](../../go/internal/domain/synch/synch.go#L14) or
+  [sync_fio_to_sheets.py:67](../../scripts/sync_fio_to_sheets.py#L67).
+- No UI surface for switching the QR account per-request (the existing
+  `?account=` query param on `/qr` keeps working as an override).
+- No backfill / dedup pass over historical rows.

+# Fix `/juniors` 500: `int + str` in reconcile allocation
+
+## Context
+
+The `/juniors` route crashes with:
+
+```
+File ".../scripts/match_payments.py", line 469, in reconcile
+    total_expected = sum(e for _, e in in_window)
+TypeError: unsupported operand type(s) for +: 'int' and 'str'
+```
+
+**Why it happens:** A junior with exactly **1 session** in a month gets an
+expected fee of the string `"?"` (manual-review marker), set in
+[attendance.py:107](scripts/attendance.py#L107). That value flows unchanged into
+the ledger as `ledger[name][m]["expected"]`
+([match_payments.py:370](scripts/match_payments.py#L370)).
+
+When a bank payment is matched to such a junior+month, the new **fill-first
+allocation** block builds `in_window` from those `expected` values and then sums
+them ([match_payments.py:469](scripts/match_payments.py#L469)) and later does
+`float(exp)` ([match_payments.py:480](scripts/match_payments.py#L480)) — both
+blow up on the string `"?"`. Adults never hit this because adults never get
+`"?"`, which is why only `/juniors` 500s.
+
+Note the final-balance code at
+[match_payments.py:511-512](scripts/match_payments.py#L511-L512) **already**
+handles this defensively (`mdata["expected"] if isinstance(..., int) else 0`).
+The allocation block added in the recent `fill-first` work simply missed the
+same guard. The intended convention is clear: a `"?"` (unknown) expected counts
+as **0** for arithmetic, so any payment landing on such a month becomes surplus
+/ positive balance rather than filling a deficit.
+
+## Approach
+
+Add one small helper and apply the existing "non-numeric expected → 0"
+convention consistently inside `reconcile()`.
+
+### 1. Helper (near the top of `scripts/match_payments.py`)
+
+```python
+def _expected_amount(value):
+    """Numeric value of an 'expected' fee; non-numeric markers like '?' → 0."""
+    return value if isinstance(value, (int, float)) else 0
+```
+
+### 2. Apply it in the allocation block
+
+- [match_payments.py:469](scripts/match_payments.py#L469):
+  `total_expected = sum(_expected_amount(e) for _, e in in_window)`
+- [match_payments.py:480](scripts/match_payments.py#L480):
+  `deficit = max(0.0, float(_expected_amount(exp)) - paid_so_far)`
+
+With expected coerced to 0 for `"?"` months:
+- A `"?"`-only payment falls into the existing `total_expected == 0` fallback
+  ([match_payments.py:495-499](scripts/match_payments.py#L495-L499)) and is
+  recorded as paid (prepayment behaviour) → shows as positive balance.
+- Mixed with real months, the `"?"` month gets deficit 0 (skipped), real months
+  fill first, surplus → credit. Consistent with line 512.
+
+### 3. Reuse the helper at line 512 (optional consistency tidy)
+
+Replace the inline `isinstance(mdata["expected"], int)` check at
+[match_payments.py:512](scripts/match_payments.py#L512) with
+`_expected_amount(mdata["paid"]/expected)` form, i.e. use `_expected_amount(...)`.
+This also closes a latent gap where a **float** exception amount would be treated
+as 0 (current check only accepts `int`).
+
+`print_report` (line 552+) iterates adults only, so it's unaffected and needs no
+change.
+
+## Verification
+
+1. `make web` and open `http://localhost:5001/juniors` — page renders 200 (was
+   500). Confirm a junior with a single-session `"?"` month who also has a
+   matched payment shows a sensible balance.
+2. `/adults` still renders unchanged (regression check).
+3. `make test` — existing reconcile tests still pass; if there is a
+   reconcile test fixture, add a case where a junior month has `expected == "?"`
+   plus a matched transaction and assert no exception + payment counted as
+   surplus.
+
+## Notes
+
+- Single-file change: [scripts/match_payments.py](scripts/match_payments.py).
+- This is a bug fix; per CLAUDE.md a small fix may go straight to `main`, but
+  confirm with the user whether to branch (`fix/junior-expected-question-mark`).
+- Add a CHANGELOG.md entry once confirmed working.
+- On execution, copy this plan to `docs/plans/<ts>-junior-expected-fix.md` per
+  the repo plan convention.

+# Plan: Limit /adults and /juniors to last N months (default 5)
+
+## Context
+
+The `/adults` and `/juniors` dashboard tables render one column per month of
+attendance/fee history. As the season accumulates months, the tables grow wider
+than the screen. The goal is to show only the **last N months** by default
+(N = 5), with N configurable via an env var, so the tables fit on screen. This
+must be implemented in **both** the Python/Flask version and the Go version,
+keeping their behavior identical.
+
+### Key correctness requirement
+
+Member **balances, credits, and debts** must continue to reflect *all* history,
+not just the visible window. Hiding older columns must not hide older debt.
+
+This is naturally satisfied because in both codebases the balance math iterates
+over the full per-member month map produced by reconcile, while only the
+*column rendering* iterates over the passed-in month list:
+
+- Python `scripts/views.py`: `settled_balance` / `_settled_balance` /
+  credits / debts loop over `data["months"].items()` (full), whereas columns,
+  totals, and per-row cells loop over `sorted_months`.
+- Go `build_adults.go` / `build_juniors.go`: `settledBalance(mr, ...)` loops
+  over `mr.Months` (full); columns/totals/cells loop over `sortedMonths`.
+
+Therefore the correct seam is: run `reconcile()` / `Reconcile()` on the **full**
+month list, then trim the list to the last N **only for the view-model builder**.
+The member-details modal also keeps full history because it reads the untrimmed
+`member_data` / `MemberData`.
+
+## Approach
+
+Add a `MONTHS_TO_SHOW` tunable (default 5; `<= 0` means "show all" as an escape
+hatch). Trim `sorted_months`/`sortedMonths` to the last N immediately before the
+view-model builder, leaving reconcile on the full list.
+
+### Python
+
+1. **`scripts/config.py`** — add, next to the existing `CACHE_TTL_SECONDS`
+   pattern (`int(os.environ.get(...))`):
+   ```python
+   MONTHS_TO_SHOW = int(os.environ.get("MONTHS_TO_SHOW", 5))
+   ```
+
+2. **`app.py`** — add a small helper (module-level) and apply it in all four
+   routes that build the adults/juniors view models:
+   ```python
+   from config import MONTHS_TO_SHOW   # add to existing config import
+
+   def _last_n_months(months):
+       return months[-MONTHS_TO_SHOW:] if MONTHS_TO_SHOW > 0 else months
+   ```
+   In each route, keep `reconcile(members, sorted_months, ...)` on the full
+   list, then pass the trimmed list to the builder:
+   ```python
+   result = reconcile(members, sorted_months, transactions, exceptions)
+   display_months = _last_n_months(sorted_months)
+   vm = build_adults_view_model(members, display_months, result, ...)
+   ```
+   Apply to: `adults_view()` (~`app.py:226`), `juniors_view()` (~`app.py:260`),
+   and the JSON twins `/api/adults` (~`app.py:161`) and `/api/juniors`
+   (~`app.py:184`) for parity.
+
+   No changes to `scripts/views.py` — it already derives `months`,
+   `raw_months`, `totals`, and per-row `row.months` from whatever month list it
+   receives, and balances/credits/debts from the full `result`.
+
+### Go
+
+1. **`go/internal/config/config.go`** — add `MonthsToShow int` to the `Config`
+   struct (~line 57-67), populate it in `Load()` (~line 80-90) with a new
+   integer helper modeled on `envDuration`:
+   ```go
+   func envInt(key string, fallback int) int {
+       if v := os.Getenv(key); v != "" {
+           if n, err := strconv.Atoi(v); err == nil {
+               return n
+           }
+       }
+       return fallback
+   }
+   ```
+   ```go
+   MonthsToShow: envInt("MONTHS_TO_SHOW", 5),
+   ```
+   (Note: unlike `envDuration`, accept `<= 0` so it can mean "show all".)
+
+2. **`go/internal/web/api/handler.go`** — in `AssembleAdults`
+   (lines 50-57) and `AssembleJuniors` (lines 71-78), keep `Reconcile` on the
+   full `sortedMonths`, then trim before the builder:
+   ```go
+   result := domreconcile.Reconcile(members, sortedMonths, txns, exceptions, time.Now().Year())
+   displayMonths := lastNMonths(sortedMonths, h.Config.MonthsToShow)
+   return buildAdultsResponse(members, displayMonths, result, txns, h.Config, time.Now().Format("2006-01")), nil
+   ```
+   Add a small helper (e.g. in handler.go):
+   ```go
+   func lastNMonths(months []string, n int) []string {
+       if n > 0 && len(months) > n {
+           return months[len(months)-n:]
+       }
+       return months
+   }
+   ```
+   No changes to `build_adults.go` / `build_juniors.go` or the templates — they
+   already derive `Months`, `RawMonths`, `Totals`, and per-row cells from the
+   passed-in `sortedMonths`, and balances/credits/debts from the full
+   `result.Members[...]`.
+
+## Critical files
+
+- `scripts/config.py` — new `MONTHS_TO_SHOW` constant.
+- `app.py` — trim helper + apply in 4 routes (HTML + JSON, adults + juniors).
+- `go/internal/config/config.go` — `MonthsToShow` field + `envInt` helper.
+- `go/internal/web/api/handler.go` — `lastNMonths` helper + apply in
+  `AssembleAdults` / `AssembleJuniors`.
+
+No template or `views.py` / `build_*.go` changes required.
+
+## Verification
+
+Python:
+- `make test` (and a targeted run, e.g.
+  `PYTHONPATH=scripts:. python -m unittest tests.test_app`).
+- `make web`, open `/adults` and `/juniors`: confirm exactly 5 month columns by
+  default, and that the **Balance** column / credits / debts are unchanged from
+  before (compare against an untrimmed run, e.g. `MONTHS_TO_SHOW=0`).
+- `MONTHS_TO_SHOW=3 make web` → 3 columns; `MONTHS_TO_SHOW=0` → all columns.
+- Spot-check that the month-range filter dropdowns and a member-details modal
+  (full history) still work.
+
+Go:
+- `cd go && go build ./... && go test ./...`.
+- Run the Go server, open `/adults` and `/juniors`: same checks as above
+  (default 5 columns, balances unchanged, `MONTHS_TO_SHOW` env override works).
+- Confirm Python and Go render the same number of columns and identical
+  balances for the same data.
+

+# Plan: Gitea Action to open a gitops image-update PR for fuj-management
+
+## Context
+
+The Go image of this app is built and pushed by the `build-go` job in
+[.gitea/workflows/build.yaml](.gitea/workflows/build.yaml), tagged
+`gitea.home.hrajfrisbee.cz/kacerr/fuj-management:<git-tag>-go` (e.g. `0.37-go`).
+
+Kubernetes manifests live in a **separate** repo,
+`gitea.home.hrajfrisbee.cz/kacerr/home-kubernetes`. Today, bumping the image in
+the `fuj-management` Deployment (namespace `fuj`) is a manual edit there.
+
+We want CI to automate that bump: when a new Go image is built, open a PR against
+`home-kubernetes` that swaps the image to the freshly built tag — using the
+`uh-cli gitops deployment update` command. The user reviews/merges that PR in
+Gitea (matching the existing branch-per-change, merge-in-browser workflow).
+
+Decisions confirmed with the user:
+- **Separate workflow file** (not a job inside build.yaml).
+- **New `GITOPS_TOKEN` secret** for home-kubernetes write + PR access.
+- **uh-cli version pinned with a default, overridable via env/var/input.**
+
+## How uh-cli works (from `/Users/jan.novak/srv/go/uh-cli/docs/`)
+
+- `uh-cli gitops deployment update` clones `--git-repo`, walks `--git-path`
+  recursively for a `kind: Deployment` whose `metadata.name`/`namespace` match,
+  edits the first container image surgically, commits on a new branch
+  `gitops/update-<name>-<timestamp>`, pushes, and **opens the PR itself** via
+  `tea pr create`. PR base is always `main`; title/body are hardcoded (no flags).
+- Requires on PATH: `git` and `tea` (tea only for the PR flow; `--force` skips it).
+- Auth: token embedded in the `--git-repo` URL (`https://user:TOKEN@host/...`);
+  `tea login add` for PR creation; git identity via `git config`/env vars.
+- `--dry-run` prints the unified diff and makes no git changes. Global `-v`
+  (placed **before** the subcommand) enables debug logging on stderr.
+- Release binaries are named `uh-cli-<version>-linux-amd64` (version includes the
+  `v`), attached to the Gitea release. Latest tag today is **`v0.1.0`**.
+
+## Change: new workflow `.gitea/workflows/gitops-update.yaml`
+
+Triggers:
+- `workflow_run` on `workflows: ["Build and Push"]`, `types: [completed]`, gated
+  to `conclusion == 'success'` — auto-fires after the image build succeeds.
+- `workflow_dispatch` with inputs: `tag` (git tag without the `-go` suffix, e.g.
+  `0.37`), `dry_run` (boolean, default false), `uh_cli_version` (optional override).
+
+Single job `gitops-pr`, `runs-on: ubuntu-latest`, in a `container: ubuntu:latest`
+for a hermetic install (matches the uh-cli CI doc pattern). Steps:
+
+1. **Install git, curl, ca-certificates, tea** — apt-get + download tea
+   `0.9.2` from `gitea.com/gitea/tea/releases/...` to `/usr/local/bin/tea`.
+2. **Install uh-cli** — download
+   `https://gitea.home.hrajfrisbee.cz/kacerr/uh-cli/releases/download/${UH_CLI_VERSION}/uh-cli-${UH_CLI_VERSION}-linux-amd64`
+   to `/usr/local/bin/uh-cli`.
+   `UH_CLI_VERSION: ${{ inputs.uh_cli_version || vars.UH_CLI_VERSION || 'v0.1.0' }}`.
+3. **Resolve image tag** — if `workflow_dispatch`, use `inputs.tag`; else use
+   `github.event.workflow_run.head_branch` (the pushed tag name). Output
+   `gitea.home.hrajfrisbee.cz/${{ github.repository }}:<tag>-go`.
+4. **Configure git identity** — `git config --global user.name/email` for the bot.
+5. **Authenticate tea** — `tea login add --name ci --url https://gitea.home.hrajfrisbee.cz --token "$GITEA_TOKEN"`.
+6. **Open image-update PR** — run, with `--dry-run` appended only when the
+   dispatch `dry_run` input is true:
+   ```
+   uh-cli -v gitops deployment update \
+     --deployment-name fuj-management \
+     --deployment-namespace fuj \
+     --set-image "<resolved image>" \
+     --git-repo "https://fuj-gitops-bot:${GITEA_TOKEN}@gitea.home.hrajfrisbee.cz/kacerr/home-kubernetes" \
+     --git-path gitops/home-kubernetes
+   ```
+
+`GITEA_TOKEN` is sourced from `secrets.GITOPS_TOKEN` at job level.
+
+Job-level guard: `if: ${{ github.event_name == 'workflow_dispatch' || github.event.workflow_run.conclusion == 'success' }}`.
+
+## Prerequisites (user must set up in Gitea — call out in handoff)
+
+1. **Create `GITOPS_TOKEN` secret** in the `fuj-management` repo: a Gitea token
+   for a user (`fuj-gitops-bot` or `kacerr`) that has **write + pull-request**
+   access to `kacerr/home-kubernetes`. The username in the `--git-repo` URL must
+   match that token's owner (adjust `fuj-gitops-bot` if using `kacerr`).
+2. **uh-cli `v0.1.0` release assets must exist** (the `uh-cli-v0.1.0-linux-amd64`
+   binary attached to the release). If not yet published, cut that release in the
+   uh-cli repo first, or set `UH_CLI_VERSION` to a published tag.
+3. **Confirm the manifest path**: `--git-path gitops/home-kubernetes` must contain
+   the `fuj-management` Deployment; `--deployment-namespace fuj` disambiguates.
+   Cannot verify from this repo — verify against home-kubernetes (narrow the path
+   if uh-cli reports an ambiguity error).
+
+## Files
+
+- **New**: `.gitea/workflows/gitops-update.yaml` (the workflow above).
+- After it works: prepend a `CHANGELOG.md` entry; save this plan to
+  `docs/plans/<ts>-gitops-pr-action.md` per CLAUDE.md convention.
+
+## Branching
+
+Feature work → branch `feat/gitops-pr-action` off `main`, commit with the
+`Co-Authored-By` trailer, push with `-u`, open the MR with
+`tea pr create --base main --head feat/gitops-pr-action`. Do not merge from CLI.
+
+## Verification
+
+1. **Dry run (manual)**: trigger `gitops-update.yaml` via workflow_dispatch with
+   `tag=0.37`, `dry_run=true`. Confirm logs show the unified diff (image line
+   `…:0.37-go`) and `-v` debug milestones; **no PR** is created.
+2. **Real run (manual)**: re-trigger with `dry_run=false`. Confirm a PR appears in
+   `home-kubernetes` against `main` with the image bump, and the PR URL is printed.
+3. **Auto-trigger**: push a new git tag to fuj-management → `Build and Push`
+   completes → `gitops-update` fires via `workflow_run` and opens the PR.
+   (Note: `workflow_run`/`head_branch` behavior depends on this Gitea/act_runner
+   version; if it doesn't fire, manual `workflow_dispatch` is the fallback and the
+   plan still delivers the core capability.)
