Stand up the Go project alongside the Python backend so both run
independently during migration. `make web-go` builds and serves on :8080;
`make web-py` (alias: `make web`) keeps the Python side on :5001.
- go/: new module `fuj-management/go` (Go 1.26)
- cmd/fuj: stdlib-flag dispatcher; `server` + `version` work,
fees/reconcile/sync/infer stubbed for M2/M4
- internal/config: env loader mirroring scripts/config.py
- internal/logging: slog setup, level taken from config
- internal/web: net/http ServeMux + request-timer middleware
- build/Dockerfile: golang:1.26 → alpine:3 multi-stage image
- .golangci.yml: govet, staticcheck, errcheck, gofumpt, unused
- Makefile: web→web-py alias; go-build/go-test/go-run/go-lint/web-go
- CI: parallel build-go job in .gitea/workflows/build.yaml (<tag>-go image)
- docs/plans/: M1 kickoff plan + progress tracker (M1 complete)
- .claude/settings.json: gofumpt + golangci-lint permissions
Gate: make go-build ✓ make go-lint ✓ make go-test ✓ curl :8080 ✓

# Changelog
|
||
|
||
## 2026-05-04 12:02 CEST — Go rewrite M1: skeleton + tooling
|
||
|
||
- Created `go/` tree with module `fuj-management/go` (Go 1.26).
|
||
- `cmd/fuj`: stdlib-flag subcommand dispatcher; `server` and `version` implemented, stubs for M2/M4 commands.
|
||
- `internal/config`: env loader mirroring `scripts/config.py` (same env var names and defaults).
|
||
- `internal/logging`: slog setup accepting log level from config.
|
||
- `internal/web`: `net/http` ServeMux on `:8080`; `middleware/timer.go` logs method/path/status/ms.
|
||
- `go/build/Dockerfile`: multi-stage (`golang:1.26` → `alpine:3`) producing a static binary image.
|
||
- Makefile: `web` → `web-py` alias; added `web-go`, `go-build`, `go-test`, `go-run`, `go-lint`.
|
||
- `.gitea/workflows/build.yaml`: parallel `build-go` job pushing `<tag>-go` image.
|
||
- Gate: `make go-build`, `make go-lint`, `make go-test`, `curl :8080` all pass.
|
||
|
||
## 2026-05-03 20:37 CEST — Fix Balance column to correctly reflect past-month debt
|
||
|
||
- Balance (and Pay-All) are now computed as `sum(paid − expected)` over past months only, iterating directly over the ledger entries from `reconcile()`.
|
||
- Previously the balance used `total_balance` (which includes current/future-month activity and out-of-window credits) plus a one-sided current-month debt adjustment. Current-month *surplus* leaked through, making the balance appear less negative than the actual past-month debt.
|
||
- Pay-All is now `max(0, −balance)` so the two values are derived from a single source and can never disagree.
|
||
- Affected: `adults_view()` and `juniors_view()` in `app.py`.
|
||
|
||
## 2026-05-03 19:26 CEST — Fee-aware allocation for multi-month payments
|
||
|
||
- `reconcile()` no longer splits a multi-month payment evenly. Allocation is now per-member with two phases: greedy (if amount ≥ total expected, each month gets exactly its expected fee and overflow → credit) and proportional (otherwise distribute by each month's expected). Fixes the case where e.g. 1250 CZK covering 3 months with mixed fees (750/350/150) marked two months red.
|
||
- Out-of-window months keep the previous even-split-to-credit behavior. Fallback to even split when all matched months have `expected = 0` (prepayment before attendance is recorded).
|
||
- Display layer only — no changes to how payments are stored in Google Sheets; `Inferred Amount` still holds the full bank amount.
|
||
- Files: [scripts/match_payments.py](scripts/match_payments.py), [tests/test_reconcile_exceptions.py](tests/test_reconcile_exceptions.py) (6 new test cases).
