-## Project
-
-COBOL 勤怠管理システム for IBM z/OS + DB2. Local dev: GnuCOBOL 3.2.0 + SQLite3 via C bridge (`tools/sqlite_bridge.c` + `tools/convert-sql.mjs`). Japanese only.
-
-| Subsystem | Prefix | Programs | DB access |
-|-----------|--------|----------|-----------|
-| A (勤怠休暇) | KIN | KIN01INP, KIN02UPD, KIN03EXP | EXEC SQL (KIN02UPD, KIN03EXP) |
-| B (残業統計) | ZAN | ZAN01CHK–ZAN06UPD (6 progs) | EXEC SQL (ZAN06UPD only) |
-| C (給与計算) | — | not yet implemented | — |
-
-Subprograms (5, no EXEC SQL): `SUB01DAT` (date), `SUB02MSG` (msg), `SUB03END` (abend), `SUB04CHK` (validation), `SUB05TIM` (rounding).
-
-Git remote: `https://gittea.dev/qiuqiuqiu/cobol-tna-system` (user `qiuqiuqiu`).
-
-## Setup & Prerequisites
-
-- Working directory **must** be project root (`Q:\202606AI-3\`)
-- `gcc`, `cobc`, `node` on PATH
-- `C:\mingw64\bin\sqlite3.dll` must exist
-- `COB_CONFIG_DIR` must be set (default `C:\mingw64\share\gnucobol\config`)
-- `COB_LIBRARY_PATH=bin` for subprogram DLLs
-
-## Build
-
-```
-tools\build.bat src\PROG.cbl  → bin\PROG.exe  (main, -x)
-tools\build.bat sub\PROG.cbl  → bin\PROG.dll   (sub, -m)
-```
-
-Auto-detects main vs sub by directory. Internal: `gcc sqlite_bridge.c` → `node convert-sql.mjs` → `cobc -I"cpy"`. Preprocessed file → `tmp\*_prep.cbl`.
-
-## Run
-
-DD names bound via env vars (prefix = first 5 chars of program ID):
-```
-set ZAN01R01=data\OVT-APPLY.DAT
-set ZAN01W01=data\OVT-VALID.DAT
-bin\ZAN01CHK.exe
-```
-PARM via command line: `bin\PROG.exe YEARMONTH=202605`.
-
-SQLite DBs: `data/OVERTIME.db` (subsystem B), `data/kin.db` (subsystem A).
-
-## Testing
-
-```
-powershell -File test\run_subsystem_b.ps1 -Scenario all
-```
-
-Scenarios: `all`, `zero`, `oneside`, `multi`, `nto1`, `overlap`, `match`, `sql-error`, `branch`.
-
-Individual program tests:
-```
-test\ZAN01\Test-ZAN01CHK.ps1 -TestCase all
-```
-
-Scripts handle data setup, SORT-emulation (PowerShell Sort-Object), pipeline execution, output verification.
-
-**Test coverage must cover**: 0件 (empty), 单边0件 (one-side zero), 复数件 (multi), N:1マッチング, 異常値, 境界値, and **all processing possibilities** (every branch, every processing function). Branch-only coverage is insufficient; every processing path must be exercised.
-
-DB initialization:
-```
-node tools\init_db_zan.mjs     # OVERTIME.db
-node tools\init_db_kin.mjs     # kin.db
-```
-
-## COBOL Conventions
-
-- **Format**: Fixed — Area A = col 8, Area B = col 12, `*` at col 7. 72-char line limit.
-- **ID pattern**: `SSSnnFFF` (ZAN01CHK, SUB01DAT)
-- **DD prefix**: first 5 chars (ZAN01R01 for ZAN01CHK)
-- **No COBOL SORT** — PowerShell `Sort-Object` replaces JCL `PGM=SORT`.
-- **File I/O**: sequential READ/WRITE only. No VSAM, random access, or REWRITE.
-- **EXEC SQL**: source kept in DB2 syntax. `tools/convert-sql.mjs` converts to `CALL 'br_exec'`/`CALL 'br_query'`/`CALL 'br_get_col'` for SQLite.
-- **Bridge COPY**: `tools/DB-COMMON.cpy` has WS-SQL-STR, SQLCODE, etc.
-- **COMP-3 host variables**: declare in `compVars` map in `convert-sql.mjs` (lines 132–136).
-- **Subprograms**: use GOBACK, never EXIT PROGRAM or STOP RUN.
-- **Output files**: write to `data/` or `tmp/`, never project root.
-
-## Critical Gotchas
-
-- **Backup first**: `copy src\PROG.cbl src\PROG-bk-YYYYMMDD-HHmm.cbl` before editing. After session, move `src/*-bk-*` → `src/old/`.
-- **INITIALIZE on PIC X** → SPACES, not `'0'`. If 88-level checks `VALUE '0'`, do explicit `MOVE '0'` after INITIALIZE.
-- **FILLER length** must match record length. Mismatch shifts reads on 2nd+ iteration.
-- **File encoding**: source files are UTF-8 with LF line endings. Fixed-length data files are ASCII. Always use `-Encoding UTF8` in PowerShell for source; never ASCII (corrupts Japanese comments).
-- **Column accuracy**: COBOL fixed format is column-sensitive. `*` at col 7, level 01 at col 8, level 03+ at col 12+. Off-by-one causes "PROCEDURE DIVISION header missing".
-- **Generated STRING blocks** in ZAN06UPD use `>>SOURCE FORMAT IS FREE`. Hand-editing requires care.
-- **Template dead-code**: inherited `*-FLG` variables (WRK-FIRST-FLG, etc.) are initialized but never referenced. Remove them in code review.
-- **復元は `bk/` または `production/` から**: safer than fixing corrupted files in `src/`.
-- **Edit COBOL via PowerShell**: `edit` tool may mismatch whitespace due to encoding. Prefer `Get-Content -Encoding UTF8` → modify array → `WriteAllLines` UTF8 no BOM.
-- **Phase 4で正常コードを「改善」しない**: working variable patterns (e.g., WRK-DIFF-MIN two-step calc) must not be refactored for readability.

-## Development Flow (7 Phases)
-
-| # | Phase | Exit condition |
-|---|-------|---------------|
-| 1 | 設計レビュー | Design review sign-off, JCL/Sort-key/COPY-book consistency checked |
-| 2 | テストケース設計 | All branch-covering + all processing-path test data ready (CSV → fixed-length via `tools/make-test-data.ps1`) |
-| 3 | 実装 | Compile OK |
-| 4 | コードレビュー | Bidirectional trace (design↔code), dead code check, JCL/file-layout match |
-| 5 | テスト実行 | All scenarios PASS (record count, field values, sort order, over/under) |
-| 6 | 文書化 | Resource list & coverage doc updated, design doc reconciled |
-| 7 | バックアップ・完了 | Backups moved to `src/old/`, full re-test PASS |
-
-## Post-Edit Checklist
-
-1. Move backups `src/` → `src/old/`
-2. Update `使用資源一覧/{PGM-ID}_使用資源一覧.md` if COPY/CALL/SELECT/DB tables changed
-3. Update `list/プログラムタイプ・ステートメントカバレッジ状況_*.txt` if statement count changed
-4. Build + run all test scenarios
-5. Verify all PASS
-6. If COPY BOOK modified, verify all programs using it
-7. Copy changed files only to `production/` (compare size or git diff; no blanket copy)

-# 進捗記録
-
-## 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）
