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.
- Split monolithic index.php into per-tool pages (ask, search, summarize,
timeline, redact, transcribe), each with its own URL and bookmarkable state
- Shared shell: includes/layout.php + layout_footer.php; shared form:
includes/tool_form.php used by all text-tool pages
- index.php now redirects authenticated users to ask.php; unauthenticated
users see the login gate only
- transcribe.php: engine selector (GPU/OpenAI/Azure), model size (small/
medium/large-v3), diarize, language, expert settings (beam, VAD, task,
initial prompt)
- api/transcribe.php: engine routing — GPU (cuttlefish), OpenAI BYOK,
Azure AI Speech; passes model/beam/task/vad/prompt to Whisper server
- tools.js: data-active-tool body attr drives setTool() on load; <a> nav
tabs skip click listeners; null guards on form/passcodeForm; engine radio
toggle shows/hides BYOK key inputs and model selector; RTF shown in status
- tools.css: styles for BYOK inputs, expert settings panel, prompt textarea
