Adds /corpus.php — a data transparency page showing what powers the
legal tools: 9 coverage categories with live doc counts, a full
sources table pulled from the corpus DB, the AI stack (LLMs, Whisper,
Qdrant, Azure AI Search, embeddings, chunking), and a pipeline flow
diagram. Stats are live via a new /api/corpus-stats.php endpoint
(queries dobetter_rag + bnl_admin). The reasoning sidebar is repurposed
as a Corpus health panel on this page.
Also ships the in-progress timeline background events toggle:
API and UI wired together via include_background param.

Add 4-language switcher (EN/NO/UK/PL), engine choice (Azure mini/full,
GPU/cuttlefish), and expandable Advanced panel (Focus, Confidence filter,
Date types) to timeline.php. Wire new params through api/timeline.php and
LegalTools::timeline() with engine routing, focus-aware prompt injection,
and confidence/date-type post-filters. Add TIMELINE_I18N to tools.js with
improved renderTimeline() confidence colour-coding and new CSS classes.
