SciDEX — Task: [Forge] Export-as-LaTeX for hypotheses, briefs, an

Tarball export with venue templates + figures + BibTeX bib + Makefile; Overleaf deep link; uses venue-templates+scientific-writing skills.

Spec File

Effort: deep

Goal

A SciDEX synthesizer brief is the closest thing the platform has to
a "publishable artifact" — it has structured sections, citations,
figures, an evidence table. But there's no path from there to a
LaTeX manuscript a researcher can import into Overleaf or submit
to a venue. The K-Dense skills bundle already ships venue-templates, scientific-writing, and latex-posters
skills; lean on them to ship a one-click "Export to LaTeX" path
that emits venue-templated .tex + a tarball of figures and a .bib. Specifically valuable for the synthesizer briefs and for
high-quality hypothesis pages.

Acceptance Criteria

☐ Module scidex/forge/latex_export.py:

export_artifact_to_latex(artifact_id, venue:
        Literal['neurips','nature_methods','plos_one',
        'arxiv_preprint']='arxiv_preprint') -> Path

returns a
path to a self-contained tarball with main.tex,
references.bib, figures/, Makefile.
- Pulls the artifact's content_md, citations, and figure
URLs from PG; converts mermaid diagrams to PDF via
existing mermaid_utils.py:render_to_pdf (or shell-out
if absent).
- Uses the venue-templates skill to fetch the right
document class and bib style.
- Citations: each attributed_evidence PMID/DOI is
resolved to a BibTeX entry via Crossref's

https://api.crossref.org/works/<doi>/transform/
        application/x-bibtex

(and PubMed for PMIDs without DOIs).

☐ Schema migrations/<date>_latex_exports.sql:

CREATE TABLE latex_exports (
        id UUID PRIMARY KEY,
        artifact_id TEXT NOT NULL REFERENCES artifacts(id),
        venue TEXT NOT NULL,
        export_path TEXT NOT NULL,
        bytes BIGINT,
        figure_count INT,
        bib_entry_count INT,
        created_by TEXT,
        created_at TIMESTAMP NOT NULL DEFAULT NOW()
      );

☐ Route GET /artifacts/{id}/export.tex.tar.gz?venue=X

streams the tarball; first call renders + caches, second
call serves from data/scidex-artifacts/exports/.

☐ Button. Every artifact page (hypothesis, brief,

analysis) gets an "Export → LaTeX" dropdown with the four
venues.

☐ Overleaf deep link. "Open in Overleaf" button posts the

tarball to https://www.overleaf.com/docs?snip_uri=...
pre-baked URL so the user lands directly in the editor.

☐ Tests tests/test_latex_export.py:

- Synthetic 3-section artifact → tarball contains the
right files; make (in a sandbox container) compiles
without errors.
- BibTeX resolution dedup (same DOI cited twice → 1 bib
entry).
- Mermaid → PDF fallback when PDF renderer absent.

☐ Smoke. Export a real synthesizer brief; attach the

compiled PDF to the Work Log.
