Item and station names such as `AID.*` come from the author's own test project on the
development system (see "Test system" in `progress.md`); they do not exist on other systems.

## How to close an issue

1. Confirm the answer with the user (practiced on the test system where possible).
2. Update **every file in the issue's "Update on close" column** with the answer.
3. Update the matching row in `knowledge/progress.md` (status and notes).
4. Set the issue to **closed** and write the resolution and date in "Next step / resolution".
   Keep closed issues in the table as history.

## Issues

| ID | Date | Area | Issue | Status | Next step / resolution | Update on close |
|---|---|---|---|---|---|---|
| ISS-001 | 2026-09-30 | ITEM (`itmval`) | Writing an item with `itmval -p -n AID.WRPS.SIM.INFLOW -v 400` added the `uoff` option flag (options 0x…8a → 0x…8e). The flag stayed after writing the original value back. Meaning of `uoff` unknown; not found in the EN manuals by text search. | open | Find what `uoff` means and how to clear it (ITEM Service IM 36K10L35/L36, Engineering Module I/O Processes IM 36K10C10). Until then, `itmval -p` stays "awaiting confirmation". | Create `.claude/skills/system-management/tasks/read-write-item.md` (with the `uoff` explanation) and add it to that skill's `SKILL.md` task table; `knowledge/progress.md` row "Write an item with `itmval -p`" |
| ISS-002 | 2026-09-30 | DATABASE (`dsschk`) | `dsschk -d ITEM_DF -v` (check only) exits 0 with no console output and nothing new in `umhlog.log`. Where results are reported is unknown. | open | Revisit with the Data Access / Data Set Service manuals; try without `-d`, or with `-e`. | Create `.claude/skills/system-management/tasks/consistency-check.md` and add it to that skill's `SKILL.md`; `knowledge/manuals/IM36K10J10-01EN.md` §4.1.1 consistency tools (add where output goes); `knowledge/progress.md` row "Consistency check" |
| ISS-003 | 2026-09-30 | DATABASE (`dssqld`) | Filtered export (`dssqld -e <out> <filter>.qli`) failed with a guessed filter syntax (`@ITEM_DF`, `@FIELD`, `@SELECT`). | open | Get the exact filter-file syntax from the Data Set Service manuals (IM 36K10L50 / P30). | `.claude/skills/system-management/tasks/export-dataset.md` section "Filtered exports"; `knowledge/manuals/IM36K10J10-01EN.md` §5.6 step 1; `knowledge/progress.md` row "Export a dataset" |
| ISS-004 | 2026-09-30 | ITEM (`itmval`) | `itmval -g -a <1..5>` returns `ITM-E-WRONG_ATT` on `AID.WRPS.*` items, so reading limits is unproven. | open | Retry on an item that has alarm limits configured (phase 8, alarms). | `.claude/skills/system-management/tasks/read-write-item.md` (limits section); `knowledge/progress.md` row "Read an item with `itmval -g`" |
