 # Changelog
 
+## 2026-05-04 23:08 CEST — fix: payment inference exact-match short-circuit
+
+- `match_members()` now short-circuits on whole-word full-name hits; nickname/partial checks only run when no full name is present.
+- Replaced bare `in` substring checks with `_word_in()` word-boundary regex throughout, closing the class of bugs where a short nickname (e.g. `tov`) matches inside another member's surname (`ottova`).
+- Added `tests/test_match_members.py` (6 cases). Affects `scripts/match_payments.py`.
+
+## 2026-05-04 23:08 CEST — feat: lower adult monthly fee to 700 CZK from April 2026
+
+- `ADULT_FEE_DEFAULT` reduced from 750 → 700 CZK.
+- `ADULT_FEE_MONTHLY_RATE` now pins Sep 2025 – Feb 2026 at 750 to preserve historical billing; Mar 2026 stays 350; Apr–May 2026 at 700. Affects `scripts/attendance.py`.
+
 ## 2026-05-04 12:02 CEST — Go rewrite M1: skeleton + tooling
 
 - Created `go/` tree with module `fuj-management/go` (Go 1.26).
