fix(sync): dashboard sync covers current year plus Nov-Dec of previous

/sync-bank now uses one shared default window in both implementations:
1 November of the previous year to 31 December of the current year.
Payments dated around New Year are picked up in January; duplicates
are still filtered by Sync ID.

Python used a hardcoded 2026 window and would have stopped syncing on
2027-01-01; Go used the current calendar year only.

Adds make sync-year [YEAR=N] with the same window. The CLI default
without flags (last 30 days) is unchanged.

 # Changelog
 
+## 2026-10-08 12:04 CEST — fix(sync): dashboard sync covers the current year plus Nov–Dec of the previous one
+
+- `/sync-bank` now uses one shared default window in both implementations: 1 November of the previous year to 31 December of the current year. Payments dated around New Year are picked up in January; duplicates are still filtered by Sync ID.
+- Python previously used a hardcoded `2026-01-01`..`2026-12-31` and would have stopped syncing on 2027-01-01; Go used the current calendar year only.
+- Added `make sync-year [YEAR=N]` with the same window; `make sync-2026` is kept. The CLI default without flags (last 30 days) is unchanged.
+- Key files: `go/internal/services/banksync/sync.go` (`DefaultWindow`), `go/cmd/fuj/main.go`, `legacy/scripts/sync_fio_to_sheets.py` (`default_sync_window`), `legacy/app.py`.
+
+## 2026-10-08 11:53 CEST — feat(fees): adult rates for 2026-07 through 2026-12, default 600
+
+- Adult default monthly rate (months not in the table): 700 → 600 CZK.
+- 2026-07 and 2026-08: 600 → 0 CZK; 2026-09 through 2026-12 added at 600 CZK (September and October were previously billed at the old 700 default).
+- The single-session fee (200 CZK) is now capped at the month's rate, so a 0-rate month is free for one session too.
+- Mirrored in `go/internal/domain/fees/fees.go` and `legacy/scripts/attendance.py`; three new parity fixtures for `calculate_fee`.
+
+## 2026-10-08 11:48 CEST — fix(ci): remove kubernetes-deploy workflow that leaked secrets to logs
+
+- Deleted `.gitea/workflows/kubernetes-deploy.yaml`. It ran on every push to every branch, deployed nothing, and echoed the Vault login response, the Kanidm API token response and the OIDC token response to the job log.
+- Deployment is handled by `gitops-update.yaml`. Repo secrets `VAULT_ROLE_ID`, `VAULT_SECRET_ID` and `K8S_CA_CERT` are now unused.
+- Follow-up outside the repo: rotate the Vault AppRole secret and the Kanidm API token, and clear old job logs.
+
 ## 2026-10-08 11:34 CEST — fix(python): return months_to_show from /api/adults and /api/juniors
 
 - Go already returned `months_to_show` in the JSON API; Python only passed it to its HTML templates. Backported the key so the API contract matches and `make parity` reports 3/3 routes.

 Tiers are set in column B of the attendance sheet:

 - `J` — Junior attending adult practices; their attendance is merged with the junior sheet
 - `X` — Excluded from junior fee calculation (coaches, etc.)
 
 ### Fee calculation
 
-- Adults: 0 sessions → 0, 1 session → 200 CZK, 2+ sessions → monthly rate (default 700 CZK)
+- Adults: 0 sessions → 0, 1 session → 200 CZK (never more than the month's rate, so a 0-rate month is free), 2+ sessions → monthly rate (default 600 CZK)
 - Juniors: 0 → 0, 1 → `"?"` (manual review required), 2+ → monthly rate (default 500 CZK)
 - Per-member per-month overrides live in the `exceptions` tab of the payments sheet (columns: Name, Period YYYY-MM, Amount, Note). Exceptions are keyed by `(normalize(name), normalize(period))`.
