All three read as primary documents. Uncontested facts are written in; six
conflicts between the documents and the KB are RECORDED AND LEFT OPEN, because
several are the user's call and one contradicts a memory entry that shaped
targeting.
New evidence
- Swisscom Zwischenzeugnis (Okt 2025) is unusually specific and now backs SW-1,
SW-2 and SW-3 verbatim: component ownership for the ETL pipelines feeding the
TERADATA DATA WAREHOUSE, Python on Kubernetes with GitLab CI/CD, AWS migration
(S3, Glue, Athena, Redshift, Airflow), 2nd/3rd-level support and on-call.
- Bosch Zeugnis corroborates BS-1 directly: "Erarbeitung und Durchfuehrung von
Integrationsstrategien fuer den Einsatz von Machine Learning Modellen in der
24/7 Fertigungsumgebung". It also confirms the BS-4 PoC framing as the
document's own wording rather than a policy hedge.
- NEW claim BS-7: "Fachliche Betreuung von Studierenden, auch im Rahmen von
Abschlussarbeiten". Documented mentoring evidence, recorded NOWHERE before
today, although "developing other engineers" is a recurring JD requirement -
SBB asked for it explicitly and the answer had to lean on team roles instead.
- Vizrt's letter is thin: testing responsibilities only. It does NOT mention the
transcoding backend, Python or C++, so VZ-1 is marked as resting on the user's
statement rather than on the document.
Six open discrepancies (claims.json: open_discrepancies_2026_09_11)
- D1 HIGH: the Bosch Zeugnis says "Ingenieur" in "Fertigungstechnologie" 1/2/3.
The words "Senior" and "Data Analysis" do not appear in it, yet the KB note
claims official_title is "the formal combined string on the Zeugnis".
- D2: KB has a promotion at 2021-01; the Zeugnis shows department moves at
2021-06 and 2022-03 and names no promotion.
- D3 HIGH: "Seit dem 01. September 2021 arbeitete Herr Thiessen in Teilzeit."
Bosch was PART-TIME for its final ~16 months. Recorded nowhere. Tenure wording
including "over ten years" was written without knowing this.
- D4 HIGH: the Swisscom Zeugnis says he uses ENGLISH, FRENCH and ITALIAN
professionally on a regular basis. Memory user_international_mobility says
"DE/EN only (no French)" - and that entry screened out French-speaking roles.
- D5 HIGH: Swisscom component ownership feeding a Teradata DWH, plus Fraunhofer
MSSQL, undercut two premises of the RUAG "Senior Data Engineer (MSSQL)"
rule-out. Talend and SAP S/4HANA are still 0 and may still carry it.
- D6 LOW: Vizrt letter says 01.07.2017-01.07.2018; KB has end 2018-05.
None of the six is resolved here. Do not quietly pick a side when writing a
document - ask.
Validator PASS, 37/37 tests.
