 Rules learned on the test system:
-- Do not put `%` in `PRINT` text: the message is cut at that point (ISS-025).
+- A single `%` in `PRINT` text cuts the message at that point; write `%%` for a literal percent

 - An object at root level has an empty `SECTION`; build names with an `IF` then (release notes).

   object creation fail.

 | ISS-006 | 2026-09-30 | HISTORY (`ithloahis`) | Samples dated before the start of the current storage unit were not stored (no error shown); samples after it were. Also, a new storage group stored nothing until CI Server was restarted. | closed | Closed 2026-10-01 (confirmed by user). Confirm with History Management (IM 36K10L20) in phase 9: how to load into older units, and whether a restart is really required. 2026-09-30 (phase 5): IM 36K10L35 §1.3/§5 explains the first part: event storage picks the unit by time stamp, never older than 60 units, and within the storage process's `gap_time` (ITHEEX/ITHEIX 2880 min) and, for EVENT/ITEM, `max_sample_delay` (ITHEIX 14400 min); older data needs earlier unit files (`hisdbg`, `hisrecover`, `isfrename`), `ithrecover <group> -p` and a restart. Practice in phase 9. 2026-10-01 (phase 9, verified): (1) restart **is** required — `CIENG_SCAN10S` / `CIENG_AGG` loaded at 11:54 and `CIENG_EVENT` reloaded at 11:32 stored nothing until the 12:00 restart, then stored at once. (2) The first unit of a new Event/Item or Aggregation group is dated 2 days back (= `gap_time` 2880 min), but samples loaded into that pre-restart unit (11:50, 30-Sep) were still dropped; samples inside the active unit (12:02) and inside a unit closed by a forced rollover (12:03 into unit 3,1) were stored. So: samples older than the first unit opened since the restart are dropped silently. Loading older data would need `hisrecover` / `isfrename` / `ithrecover` (not practiced). Proposed close: documented in `load-history.md` and skill `history-management`. | `.claude/skills/system-management/tasks/load-history.md`; `examples/CI-Eng-Sample/README.md`; `knowledge/manuals/IM36K10J10-01EN.md` command-line tools |

Which component and certificate is not known. | closed | Closed 2026-10-01 (confirmed by user): cause known, ODBC server left as is (not licensed/used on the test system). Identify in phase 7. 2026-10-01 (phase 7): cause found. The message comes from the ODBC server `odbsrv` (ACCESS Service, Simba): `odbsrv.sup` has `USESSL = YES` and `access_start.cmd` points it at `%TLS_ROOT_PATH%\tls\pki\odbsrv\SampleServerCertificate.pem` / `SampleServerKey.pem`, but that folder does not exist and no sample certificate is installed. `odbsrv` exits right after start (`DUR-W-REM_PROC, Process ODBSRV exited unexpectedly`), port 1583 does not listen.

 | ISS-010 | 2026-09-30 | ITEM (sub-items) | The Integrator sub-item adds value × seconds; setting `TIME_UNIT` = Hour made no difference (1 per second while the main item was 1). The Tutorial lists a time unit only for Rate-of-Change. | closed | 2026-09-30 (phase 5): IM 36K10C10 §3.2 and `itm.sup` answer it: the integral is divided by the **integration granule** `itm_int_secs` (label "Integration granule, sec.") in `itm.sup` — **system-wide**, installed value 1 (seconds); 60 = minutes, 3600 = hours. `TIME_UNIT` only applies to Rate-of-Change. Practiced 2026-09-30: set to 60 and restarted → `CI-Eng-Sample.PUMP1.RUNNING.RUN_SECONDS` rose exactly 1.0 in 60 s; restored to 1 (file identical to backup) → 8 in 8 s.

Confirm with History Management (IM 36K10L20) in phase 9: how to load into older units, and whether a restart is really required. 2026-09-30 (phase 5): IM 36K10L35 §1.3/§5 explains the first part: event storage picks the unit by time stamp, never older than 60 units, and within the storage process's `gap_time` (ITHEEX/ITHEIX 2880 min) and, for EVENT/ITEM, `max_sample_delay` (ITHEIX 14400 min); older data needs earlier unit files (`hisdbg`, `hisrecover`, `isfrename`), `ithrecover <group> -p` and a restart. Practice in phase 9. 2026-10-01 (phase 9, verified): (1) restart **is** required — `CIENG_SCAN10S` / `CIENG_AGG` loaded at 11:54 and `CIENG_EVENT` reloaded at 11:32 stored nothing until the 12:00 restart, then stored at once. (2) The first unit of a new Event/Item or Aggregation group is dated 2 days back (= `gap_time` 2880 min), but samples loaded into that pre-restart unit (11:50, 30-Sep) were still dropped; samples inside the active unit (12:02) and inside a unit closed by a forced rollover (12:03 into unit 3,1) were stored.

Confirm with History Management (IM 36K10L20) in phase 9: how to load into older units, and whether a restart is really required. 2026-09-30 (phase 5): IM 36K10L35 §1.3/§5 explains the first part: event storage picks the unit by time stamp, never older than 60 units, and within the storage process's `gap_time` (ITHEEX/ITHEIX 2880 min) and, for EVENT/ITEM, `max_sample_delay` (ITHEIX 14400 min); older data needs earlier unit files (`hisdbg`, `hisrecover`, `isfrename`), `ithrecover <group> -p` and a restart. Practice in phase 9. 2026-10-01 (phase 9, verified): (1) restart **is** required — `CIENG_SCAN10S` / `CIENG_AGG` loaded at 11:54 and `CIENG_EVENT` reloaded at 11:32 stored nothing until the 12:00 restart, then stored at once. (2) The first unit of a new Event/Item or Aggregation group is dated 2 days back (= `gap_time` 2880 min), but samples loaded into that pre-restart unit (11:50, 30-Sep) were still dropped; samples inside the active unit (12:02) and inside a unit closed by a forced rollover (12:03 into unit 3,1) were stored. So: samples older than the first unit opened since the restart are dropped silently. Loading older data would need `hisrecover` / `isfrename` / `ithrecover` (not practiced).

Confirm with History Management (IM 36K10L20) in phase 9: how to load into older units, and whether a restart is really required. 2026-09-30 (phase 5): IM 36K10L35 §1.3/§5 explains the first part: event storage picks the unit by time stamp, never older than 60 units, and within the storage process's `gap_time` (ITHEEX/ITHEIX 2880 min) and, for EVENT/ITEM, `max_sample_delay` (ITHEIX 14400 min); older data needs earlier unit files (`hisdbg`, `hisrecover`, `isfrename`), `ithrecover <group> -p` and a restart. Practice in phase 9. 2026-10-01 (phase 9, verified): (1) restart **is** required — `CIENG_SCAN10S` / `CIENG_AGG` loaded at 11:54 and `CIENG_EVENT` reloaded at 11:32 stored nothing until the 12:00 restart, then stored at once. (2) The first unit of a new Event/Item or Aggregation group is dated 2 days back (= `gap_time` 2880 min), but samples loaded into that pre-restart unit (11:50, 30-Sep) were still dropped; samples inside the active unit (12:02) and inside a unit closed by a forced rollover (12:03 into unit 3,1) were stored. So: samples older than the first unit opened since the restart are dropped silently. Loading older data would need `hisrecover` / `isfrename` / `ithrecover` (not practiced).

The trend has 4 further empty pens. 2026-10-01 later: the trend also had the property `chart.attribute[00]` connected to `TANK1.LEVEL` (added by mistake with the pen); the Operator Interface (desktop) showed *Short attribute name ( 61.0) is invalid*. After removing it the desktop trend draws the line, but the HTML trend still logs the mismatch error. | open | Tried 2026-10-01 (fresh session after a restart, 283 history samples in the hour): removing the 4 empty pens, and `updating` true / `updateInterval` 10 like the factory `AOG_TrendOpen` — the mismatch error and the empty trend stayed in both cases (changes reverted). Still to try: a Micro Trend, the HTML-supported trend properties (IM 36K10R30 §4.8.7), clearing the browser/`MO_CACHE_DISPLAYS` cache (the console shows `CIENG_Tank.xml` *loaded (from cache)*), and adding the pen to the factory *Open Trend* display in the HTML client. | `.claude/skills/graphics/tasks/create-display.md`; `knowledge/manuals/IM36K10R30-01EN.md` §4 |

(2) App. 1 explanations of `SHELVE` and `UN-SHELVE` are swapped. (3) `QUESIZE`: manual default and maximum 200 kB, `adtsys.sup` help default 10 kB, minimum 10 (file sets 200). (4) `TIMEFMT` default: manual `DD/MM/YY hh:mm:ss.ppp`, `adtsys.sup` help without `.ppp`; `ADTLOG` output shows milliseconds (manual right). (5) `dssqld` changes are recorded with source `ENT-ENG-MOD`, not `QUICKLOAD`. (6) The selection expression language is not described in the manual; the compiler listing gives the words and operators (no `LIKE`).
