New surface at /deep-research.php where the user pastes a question or
uploads PDF/DOCX/TXT case files and a LLM-orchestrated agent researches
the Do Better Norge legal corpus from 3-5 angles, with hybrid retrieval,
cross-encoder rerank, and synthesis that emits an inline-[n]-cited
markdown brief plus a numbered sources panel.
Uploaded documents are chunked + embedded in memory only (nomic-embed-text
via LiteLLM) and searched alongside the shared corpus during the same
request — never persisted to disk, DB, or Qdrant.
Reuses ClientRagPipeline::searchAll (hybrid + rerank), dbnV6 slice
helpers, and the existing extract.php text-extraction logic via a new
dbnToolsExtractUploadedFile() helper. Also adds dbnToolsCallGpuLlm()
helper in bootstrap.php — fixes a latent bug where LegalTools.php
was already calling that name with no definition.
Search.php is unchanged.
- Extract limit raised from 32K to 128K chars per file (long legal docs now fit)
- Redact API body/text limits raised (400KB / 128K chars) to match
- Upload zone accepts multiple files (up to 5); extracted text concatenated with
doc separator and combined before redaction; shows per-file char counts
- LLM redact pass now infers contextual person roles (FATHER, MOTHER, CHILD,
ATTORNEY, JUDGE, etc.) instead of generic [PERSON] for all names; same
individual gets consistent tag throughout the document
- Tag validation widened to allow any [A-Za-z0-9_- ] pattern (not just the
five hardcoded tags), supporting contextual and alias tags
- Alias UI added to Redact mode: user maps real names to bracketed aliases
(e.g. "David Jr" -> [Junior]); aliases injected into LLM system prompt as
override instructions; max 20 aliases, 100 chars each
- max_tokens raised from 2000 to 4000; timeout from 60s to 90s for larger docs

api/extract.php — new endpoint accepting .pdf/.docx/.txt up to 4 MB;
pdftotext for PDFs, ZipArchive+DOMXPath for DOCX, mb_convert_encoding
for TXT; truncates to 32 000 chars to stay within redact limit.
index.php — drop/browse upload zone above the textarea, visible only
in Redact mode.
tools.js — setupUpload(), handleFileUpload(), resetUpload(); drag-and-drop
and file picker both call the extract endpoint then populate the textarea.
tools.css — upload zone, drag-over, file-info, clear button styles.
