refactor: move Python implementation to legacy/, make Go primary

Go (go/) becomes the primary implementation. The original Python version moves to legacy/ and is kept runnable; new features are still built in both (see the Dual implementation rule in CLAUDE.md). - git mv app.py, scripts/, templates/, tests/, pyproject.toml, uv.lock and build/ into legacy/ - Makefile: Python targets point at legacy/, venv in legacy/.venv, CREDENTIALS_PATH exported for the root .secret/ file - CI and make image build the Python image with legacy/ as context; the Makefile is no longer copied into the image - legacy/.dockerignore moved to the context root so it takes effect - CLAUDE.md, docs/README.md, Go comments, fixture README, capture script and VS Code launch config updated to the new layout Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

 # Changelog
 ## 2026-10-08 11:33 CEST — refactor: move Python implementation to legacy/, Go is primary
 - Go (`go/`) is now the primary implementation. The original Python version moved to `legacy/` (`app.py`, `scripts/`, `templates/`, `tests/`, `pyproject.toml`, `uv.lock`, `build/`) and is considered legacy; new features are still built in both.
 - `CLAUDE.md` rewritten for the Go-first layout, with a "Dual implementation rule" section.
 - Makefile Python targets keep their names and point at `legacy/`; virtualenv is `legacy/.venv`, Python cache is `legacy/tmp/`; `CREDENTIALS_PATH` is exported pointing at the root `.secret/` file.
 - CI builds the Python image with `legacy/` as context; the image no longer contains the Makefile. `legacy/.dockerignore` now takes effect and excludes nested `__pycache__`.
 - Go comments, fixture README, capture script and VS Code launch config updated to the new paths.
 ## 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`.
 ## 2026-05-11 23:58 CEST — fix(reconcile): fill earliest month deficit first in multi-month allocations
 - Multi-month payment allocation now fills the earliest in-window deficit first and spills
  any remainder to later months, accounting for prior transactions' contributions to each month.
  Previously a single transaction was split proportionally to each month's total expected fee,
  ignoring what earlier transactions had already paid — surfaced by Matyáš Thér's 200+550 case
  showing 566/183 instead of 500/250.
 - Files: `scripts/match_payments.py`, `go/internal/domain/reconcile/reconcile.go`, tests, parity fixtures.
 ## 2026-05-11 22:56 CEST — fix(python): parse Fio 2-digit-year dates + add `make sync-debug` dry-run tool
 - 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"))`.

+Financial management system for FUJ (Frisbee Ultimate Jablonec). Handles attendance-based fee calculation, Fio bank transaction sync, payment reconciliation, and a web dashboard.
 - **Go is the primary implementation** (`go/`). It is the version that is built, deployed and developed first.
 - **Python is legacy** (`legacy/`). The project was originally developed in Python (Flask); that version is kept runnable and in sync, but is considered legacy from now on.
 ## Dual implementation rule
 Until the Python version is retired, **every new feature and every behaviour change must be implemented in both Go and Python**:
 1. Implement and test in Go first (`go/`).
 2. Mirror the change in the legacy Python code (`legacy/`), including its tests.
 3. Keep the two in parity: shared constants (fee rates, merged months, bank accounts, sheet IDs) must match on both sides, and the JSON API contract (`/api/adults`, `/api/juniors`, `/api/payments`) must stay identical. The HTML frontends are allowed to diverge.
 4. If a pure function's behaviour changes, add or update seeds in `legacy/scripts/_fixture_seeds.py`, run `make capture-fixtures`, and make sure `make go-test-all` passes. With both servers running, `make parity` diffs the live JSON APIs.
 Go-only or Python-only changes are fine for things that exist on one side only (build, tooling, HTML/CSS/JS, refactors with no behaviour change).
 ## Key Constraints
 - **PII separation**: Member data (names, emails, payment info) must never be committed to git. Enforce config/data separation from day one.
- **Configuration**: External service IDs, credentials, and tunable parameters are centralized in `scripts/config.py`. Domain-specific constants (fees, merged months) stay in their respective modules.
+- **Configuration**: External service IDs, credentials, and tunable parameters are centralized in `go/internal/config/config.go` (mirrored in `legacy/scripts/config.py`). Domain-specific constants (fees, merged months) stay in their respective modules.
 ## Development Setup
-This project uses `uv` for dependency management.
+Go (primary): a recent Go toolchain (see `go/go.mod`) and `golangci-lint`.
 ```bash
-uv venv && uv sync
+make go-build     # builds bin/fuj
 source .venv/bin/activate
 ```
-Set `PYTHONPATH=scripts:.` when running scripts directly (the Makefile does this automatically).
+Python (legacy) uses `uv`; the project file and virtualenv live in `legacy/`.
 ```bash
 make venv         # uv sync --project legacy  →  legacy/.venv
 ```
 The Makefile sets `PYTHONPATH` (`legacy/scripts:legacy`) and `CREDENTIALS_PATH` (`.secret/fuj-management-bot-credentials.json` at the repo root) for the Python targets. Set both yourself when running Python scripts directly.

+### Repository layout
- `app.py` — Flask app; routes for `/adults`, `/juniors`, `/payments`, `/sync-bank`, `/qr`, `/flush-cache`
+- `go/` — primary implementation (single binary `fuj`, templates and static assets embedded).
- `scripts/attendance.py` — Fetches attendance CSV from Google Sheets, computes per-member per-month fees. Contains fee rate constants (`ADULT_FEE_DEFAULT`, `JUNIOR_FEE_DEFAULT`) and `ADULT_MERGED_MONTHS` / `JUNIOR_MERGED_MONTHS` dicts.
+- `legacy/` — legacy Python implementation (`app.py`, `scripts/`, `templates/`, `tests/`, `pyproject.toml`, `build/Dockerfile`).
- `scripts/match_payments.py` — `reconcile()` matches transactions to members/months. `fetch_sheet_data()` reads the payments sheet. `fetch_exceptions()` reads the `exceptions` tab.
+- `docs/` — documentation; `docs/plans/` holds plans and task lists.
- `scripts/cache_utils.py` — Invalidation via Google Drive API `modifiedTime`; falls back to 5-minute TTL buckets when Drive API is unavailable. Cache files live in `tmp/`.
+- `.gitea/workflows/` — CI: image builds on tag push, gitops image-update PR.
- `scripts/sync_fio_to_sheets.py` — Pulls Fio bank transactions and appends them to the payments Google Sheet.
+
- `scripts/infer_payments.py` — Fills in Person/Purpose/Inferred Amount columns using name-matching heuristics.
+### Key modules — Go (primary)
- `scripts/config.py` — All external IDs, paths, and tunable TTLs. Override via env vars (`CREDENTIALS_PATH`, `BANK_ACCOUNT`, `CACHE_TTL_SECONDS`).
+
 - `go/cmd/fuj` — CLI entry point; subcommands `server`, `fees`, `reconcile`, `sync`, `infer`, `version`.
 - `go/cmd/parity` — diffs the JSON API of the Go and Python servers.
 - `go/internal/config` — sheet IDs, bank accounts, env-driven settings (`CREDENTIALS_PATH`, `CACHE_DIR`, `CACHE_TTL_SECONDS`, `CACHE_API_CHECK_TTL_SECONDS`, `MONTHS_TO_SHOW`, `SERVER_ADDR`, `LOG_LEVEL`, `FIO_API_TOKEN_NEW` / `FIO_API_TOKEN_OLD`).
 - `go/internal/domain` — pure logic: `fees` (rates, `CalculateFee`, `CalculateJuniorFee`), `reconcile`, `matching` (name matching, inference), `czech` (normalize, month parsing), `money`, `synch` (sync IDs).
 - `go/internal/io` — external systems: `attendance` (CSV export), `sheets`, `drive`, `fio` (API + transparent-page scraper), `cache` (file cache). Each has a fake for tests.
 - `go/internal/services` — `membership` (loading, merged months, fee and reconcile reports) and `banksync` (Fio sync + inference).
 - `go/internal/web` — routes for `/adults`, `/juniors`, `/payments`, `/sync-bank`, `/flush-cache`, `/qr`, `/version`, `/api/*`; `templates/` and `static/` are embedded.
 - `go/tests` — parity tests and the scrubbed fixture corpus captured from Python.

 - `legacy/scripts/attendance.py` — Fetches attendance CSV from Google Sheets, computes per-member per-month fees. Contains fee rate constants (`ADULT_FEE_DEFAULT`, `JUNIOR_FEE_DEFAULT`) and `ADULT_MERGED_MONTHS` / `JUNIOR_MERGED_MONTHS` dicts.
 - `legacy/scripts/match_payments.py` — `reconcile()` matches transactions to members/months. `fetch_sheet_data()` reads the payments sheet. `fetch_exceptions()` reads the `exceptions` tab.
 - `legacy/scripts/cache_utils.py` — Invalidation via Google Drive API `modifiedTime`; falls back to 5-minute TTL buckets when Drive API is unavailable. Cache files live in `legacy/tmp/`.
 - `legacy/scripts/sync_fio_to_sheets.py` — Pulls Fio bank transactions and appends them to the payments Google Sheet.
 - `legacy/scripts/infer_payments.py` — Fills in Person/Purpose/Inferred Amount columns using name-matching heuristics.
 - `legacy/scripts/views.py` — View models shared by the HTML routes and the JSON API.
 - `legacy/scripts/config.py` — All external IDs, paths, and tunable TTLs. Override via env vars (`CREDENTIALS_PATH`, `CACHE_TTL_SECONDS`, `MONTHS_TO_SHOW`).
 - `legacy/scripts/capture_fixtures.py`, `scrub_fixtures.py`, `_fixture_seeds.py` — produce the scrubbed parity fixtures for Go.
 ### Member tiers
 Tiers are set in column B of the attendance sheet:
- `A` — Adult, pays fees (per-month rate from `ADULT_FEE_MONTHLY_RATE`, fallback 700 CZK for 2+ sessions; 200 CZK for exactly 1)
+- `A` — Adult, pays fees (per-month rate from `AdultFeeMonthlyRate` / `ADULT_FEE_MONTHLY_RATE`, fallback 700 CZK for 2+ sessions; 200 CZK for exactly 1)
 - `J` — Junior attending adult practices; their attendance is merged with the junior sheet
 - `X` — Excluded from junior fee calculation (coaches, etc.)

 # Fill-first multi-month payment allocation
 ## Context
 Matyáš Thér paid in two transactions:
 | # | Amount | Purpose             |
 |---|--------|---------------------|
 | 1 | 200    | `2026-02`           |
 | 2 | 550    | `2026-02, 2026-03`  |
 Total 750 = his expected fee for the two months (likely 2026-02 = 500, 2026-03 = 250 — junior tier or exception-adjusted). The app currently shows 2026-02 = **566** paid, 2026-03 = **183** paid. The user wants:
 > First use the second payment for the rest of 2026-02 (no more, no less), then put the remainder toward 2026-03.
 Both Python ([scripts/match_payments.py](scripts/match_payments.py)) and Go ([go/internal/domain/reconcile/reconcile.go](go/internal/domain/reconcile/reconcile.go)) have the same bug: when a single transaction's `in_window_share` is less than the sum of in-window expected fees, both fall into a **proportional** branch that splits the new transaction across months in proportion to each month's *total* expected fee — never consulting what prior transactions already paid into earlier months.
 Trace for txn 2:
 - `in_window = [(2026-02, 500), (2026-03, 250)]`, `total_expected = 750`, `in_window_share = 550`.
 - `550 < 750` → proportional:
  - 02 alloc = `550 × 500 / 750 = 366.67`
  - 03 alloc = `550 − 366.67 = 183.33`
 - Combined with txn 1's 200 → 02 = 566.67, 03 = 183.33 → display `566 / 183`. ✓ matches reported numbers.
 The fix: replace the greedy + proportional branches with a single **fill-first** loop that iterates `in_window` in user-supplied order (already chronological by convention from [scripts/infer_payments.py:151](scripts/infer_payments.py#L151)) and allocates `min(remaining, max(0, expected − paid_so_far))` to each month, with any final surplus going to the credit bucket. This collapses three cases (greedy / proportional / pure overflow) into one and naturally consults the ledger's `paid` field which is already updated by prior transactions in the same reconcile pass.
 The even-split branch (`total_expected == 0`, prepayment before fees known) stays untouched — different semantic, folding it in would silently change behavior.
 ## Changes
 ### Python — [scripts/match_payments.py:471-498](scripts/match_payments.py#L471-L498)
 Replace both `total_expected > 0` branches (current lines 471–498) with a single unified loop. Keep lines 466–469 above and the even-split fallback below (lines 499–510) as-is.
 ```python
            if total_expected > 0:
                # Fill-first: iterate in_window in matched_months order (chronological by
                # convention), allocate min(remaining, deficit) to each month, where
                # deficit accounts for prior transactions already credited to that month.
                # Any surplus after all in-window deficits are covered → credit bucket.
                remaining = in_window_share
                for m, exp in in_window:
                    paid_so_far = ledger[member_name][m]["paid"]
                    deficit = max(0.0, float(exp) - paid_so_far)
                    alloc = min(remaining, deficit)
                    if alloc <= 0:
                        continue
                    ledger[member_name][m]["paid"] += alloc
                    ledger[member_name][m]["transactions"].append({
                        "amount": alloc,
                        "date": tx["date"],
                        "sender": tx["sender"],
                        "message": tx["message"],
                        "confidence": confidence,
                    })
                    remaining -= alloc
                if remaining > 0:
                    credits[member_name] = credits.get(member_name, 0) + int(remaining)
            else:
                # … existing even-split branch (lines 499–510) unchanged …
 ```
 Note: skipping the `transactions.append` when `alloc <= 0` (e.g. month already fully paid by a prior txn) avoids zero-amount ghost rows in the per-month transaction list. This is a small UI-visible side effect; before committing, grep tests for assertions on `len(transactions)` per month to confirm nothing relies on the current "one row per (txn, month) regardless of alloc" behavior.
 ### Go — [go/internal/domain/reconcile/reconcile.go:320-357](go/internal/domain/reconcile/reconcile.go#L320-L357)
 Same shape — replace both `totalExpected > 0` branches. Even-split branch (lines 358–372) stays.
 ```go
            if totalExpected > 0 {
                // Fill-first; see Python reconcile() for rationale.
                remaining := inWindowShare
                for _, mw := range inWindow {
                    md := ledger[memberName][mw.month]
                    deficit := float64(mw.expected) - md.Paid
                    if deficit < 0 {
                        deficit = 0
                    }

                    })
                    ledger[memberName][mw.month] = md
                    remaining -= alloc
                }
                if remaining > 0 {
                    credits[memberName] += int(remaining)
                }
            } else {
                // … existing even-split branch (lines 358–372) unchanged …
            }
 ```
 ### Tests
 #### Python — [tests/test_reconcile_exceptions.py](tests/test_reconcile_exceptions.py)
 1. **Rewrite `test_proportional_underpayment`** ([line 96](tests/test_reconcile_exceptions.py#L96)) — its current assertions (`paid_02 < 750`, `paid_03 < 350`, `paid_04 < 750`, and 02/04 equal allocation) are incompatible with fill-first. Under fill-first with the same fixture (1250 across `02:750, 03:350, 04:750`):
   - 02: `min(1250, 750) = 750` (full) → remaining 500
   - 03: `min(500, 350) = 350` (full) → remaining 150
   - 04: `min(150, 750) = 150` (partial) → remaining 0
   Replace assertions with these exact expected values, rename to `test_underpayment_fills_earliest_first`.
 2. **Add `test_fill_first_across_two_transactions`** — the Matyáš regression:
   ```python
   def test_fill_first_across_two_transactions(self):
       """Prior txn fills 02 partially; later txn finishes 02 then spills to 03."""
       members = [('Matyáš', 'A', {'2026-02': (500, 2), '2026-03': (250, 1)})]
       sorted_months = ['2026-02', '2026-03']
       tx1 = _tx('Matyáš', '2026-02', 200)
       tx2 = _tx('Matyáš', '2026-02, 2026-03', 550)
       result = reconcile(members, sorted_months, [tx1, tx2])
       months = result['members']['Matyáš']['months']
       self.assertAlmostEqual(months['2026-02']['paid'], 500, places=2)
       self.assertAlmostEqual(months['2026-03']['paid'], 250, places=2)
   ```
 3. `test_greedy_exact_match`, `test_greedy_overpayment_goes_to_credit`, `test_single_month_unchanged`, `test_two_members_multi_month` should pass unchanged — fill-first agrees with greedy when payment ≥ total expected.
 #### Go — [go/internal/domain/reconcile/reconcile_test.go](go/internal/domain/reconcile/reconcile_test.go)
 - Add `TestUnderpaymentFillsEarliestFirst` mirroring the rewritten Python test.
 - Add `TestFillFirstAcrossTwoTransactions` mirroring the Matyáš scenario.
 #### Parity — [go/tests/parity/reconcile/reconcile_parity_test.go](go/tests/parity/reconcile/reconcile_parity_test.go)
 Add a fixture for the Matyáš two-transaction case. Since both implementations change together and Python remains canonical, existing parity fixtures should continue to pass; verify after edits.

 ```markdown
 ## 2026-05-11 23:55 CET — fill-first multi-month payment allocation
 - Multi-month payment allocation now fills the earliest in-window deficit first
  and spills the remainder to later months, accounting for prior transactions'
  contributions. Previously a single transaction was split proportionally to
  each month's total expected fee, ignoring earlier payments — surfaced by
  Matyáš Thér's two-payment 200+550 case showing 566/183 instead of 500/250.
 - scripts/match_payments.py, go/internal/domain/reconcile/reconcile.go, tests.

 ## Critical files
 - [scripts/match_payments.py](scripts/match_payments.py) — Python reconcile (canonical)
 - [go/internal/domain/reconcile/reconcile.go](go/internal/domain/reconcile/reconcile.go) — Go reconcile (mirrors Python)
 - [tests/test_reconcile_exceptions.py](tests/test_reconcile_exceptions.py) — rewrite `test_proportional_underpayment` + add Matyáš test
 - [go/internal/domain/reconcile/reconcile_test.go](go/internal/domain/reconcile/reconcile_test.go) — add Go tests
 - [go/tests/parity/reconcile/reconcile_parity_test.go](go/tests/parity/reconcile/reconcile_parity_test.go) — add parity fixture
 - [CHANGELOG.md](CHANGELOG.md) — top entry
 ## Verification
 1. `make test` — Python unit tests including the rewritten + new fill-first tests.
 2. `cd go && go test ./internal/domain/reconcile/... ./tests/parity/reconcile/...` — Go unit + parity tests.
 3. `make web` → load `/adults` or `/juniors` (whichever lists Matyáš Thér) → his 2026-02 row should be fully paid (no shortfall), 2026-03 fully paid, no leftover credit.
 4. Spot-check one other multi-month-purpose member to make sure fully-covered cases still look right.
 ## Branch & MR (per CLAUDE.md)
 1. `git checkout -b fix/fill-first-multi-month-allocation`
 2. Apply edits + tests + CHANGELOG entry.
 3. `make test && (cd go && go test ./...)` — both green.

  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.
 ## Housekeeping
 - Per `CLAUDE.md`, copy this plan to
  `docs/plans/YYYY-MM-DD-HHMM-months-to-show.md` during implementation (create
  `docs/plans/` if missing) and add a `CHANGELOG.md` entry once verified.
 - Per `CLAUDE.md`, this is a feature → do it on a `feat/months-to-show` branch
  and open a Gitea MR with `tea`; do not commit to `main`.

 # 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`

 - `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.)

kacerrandClaude Opus 5.5	022facc957	refactor: move Python implementation to legacy/, make Go primary Deploy to K8s / deploy (push) Successful in 20s Details Go (go/) becomes the primary implementation. The original Python version moves to legacy/ and is kept runnable; new features are still built in both (see the Dual implementation rule in CLAUDE.md). - git mv app.py, scripts/, templates/, tests/, pyproject.toml, uv.lock and build/ into legacy/ - Makefile: Python targets point at legacy/, venv in legacy/.venv, CREDENTIALS_PATH exported for the root .secret/ file - CI and make image build the Python image with legacy/ as context; the Makefile is no longer copied into the image - legacy/.dockerignore moved to the context root so it takes effect - CLAUDE.md, docs/README.md, Go comments, fixture README, capture script and VS Code launch config updated to the new layout Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-08 11:33:57 +02:00

Adds %d.%m.%y and %d/%m/%y to the format list, mirroring the Go-side fix from 2026-05-07. Also adds a Python analog of make go-sync-debug: - --dry-run skips header write / append / sort and prints "would …" lines - --print-fio-table prints aligned per-txn table with NEW/DUP status - make sync-debug [DAYS=N] wrapper (default DAYS=30) - always-on stderr diagnostics in fio_utils: which fetcher was chosen (with FIO_API_TOKEN-unset lag warning) + raw-vs-filtered counts, so this class of "scraper drops everything" bug surfaces immediately.
