Curated knowledge base from the first batch of Lexis 360 PDF exports
(LexisNexis "Lexis Briefings Personalrecht", 55 documents, source
Stands 2024-03 to 2026-09). Purpose: development reference alongside
RECHTSQUELLEN-*.md and a retrieval-ready corpus for a future
question-answering copilot.
Licensing split (decision D1): the PDF exports and the extracted full
texts stay local and unversioned (Lexis360/ gitignored, like
.firecrawl/); only the curation in own words with short quotes and
source citations is versioned.
- wissensbasis/dokumente/: one curated entry per briefing (55) with
approved frontmatter (frozen lb-<cluster>-<nn> ids, English
structural keys, German values, stand YYYY-MM, ASCII topic/tags
slugs) and sections Zusammenfassung, Kernwerte & Fristen (Stand
marked), Rechtsgrundlagen (only citations actually in the source,
verified/plausible/open marks), Payroll-Relevanz (Odoo), Verweise
- clusters: altersteilzeit 15, lehrlinge 15, jugendliche 7,
ferialpraktikanten 4, beschaftigungsformen 8, teilzeit 6
- kb.json + INDEX.md: generated from the frontmatter by --registry
(single source of truth, schema-validated)
- tools/build_lexis_kb.py: stdlib-only pipeline - --extract
(pdftotext, breadcrumb/stand parsing incl. dossier-style exports
with wrapped breadcrumbs), --registry (frontmatter validation:
required keys, id pattern, id prefix vs topic, stand format,
dangling cross_refs), --check (layer 1 <-> layer 2 completeness);
ids are frozen across batches, numbers never reused
- RUNBOOK.md: batch intake workflow, validation steps, known
limitations
Corpus contradictions flagged in the entries (not silently resolved):
AMS replacement rate for blocked Altersteilzeit 2026 (lb-atz-07 28.5%
vs lb-atz-09/12 27.5%), DAG limit 2023 (751.36 vs 751.37 EUR),
Kurzarbeit for Lehrlinge (lb-leh-11 vs lb-leh-07); lehrlinge cluster
partly older Stands (2024-03/2025-08).
Validated: extract 55/55, registry 55 entries/6 clusters, check 0
problems, structural scan of all 55 curated entries, py_compile.
