## Session 2026-06-24

### Goal
Complete Subsystem A FILE STATUS consistency fix and KIN07DAI 9999ABDSOR reachability.

### Done
- FILE STATUS + OPEN error checks added to all 6 KIN programs (KIN01INP/KIN02UPD/KIN03EXP/KIN04CHK/KIN06CLD/KIN07DAI)
- KIN06CLD: added missing 9999ABDSOR section
- All 6 programs build OK
- Subsystem A tests PASS (KIN04CHK/KIN06CLD/KIN07DAI — no tests exist for KIN01INP/KIN02UPD/KIN03EXP)
- \production/\ synced (source + exe)
- Git commit + push (\47866d2\, \master → master\)

### Design Review Note
FILE STATUS is a standard COBOL I/O implementation detail, not design-level business logic. The design documents do not need to reflect FILE STATUS declarations or OPEN STATUS checks. Code and design docs are consistent.

### Next Session
- Subsystem A テスト拡充（KIN01INP/KIN02UPD/KIN03EXP のテストスクリプト作成）
- Subsystem B の継続（次のタスクを確認）
