Report Skill

Render research outputs into self-contained HTML using Jinja2 templates and matplotlib charts. Install with uv sync --extra report. Default output uses QUANTSPACE_REPORTS_ROOT when set, otherwise the workspace reports/ path.

Complete research archives are HTML only. Do not write them as Markdown or PDF. Do not use a database. Other skills must not write HTML; they return objects, and the caller fills ResearchReport then calls write_research_bundle.

Two output paths

Path	Entry	Output	Use for
Complete research archive	`ResearchReport` + `write_research_bundle`	`reports/<namespace>/<slug>/index.html`	Takeaway research document, including public examples
Dashboard preview	`ReportRenderer` + `factor_report` / `backtest_report` / `signal_digest`	one HTML file	Quick look, not an archive

Charts are inlined as base64 data URIs via the png_data_uri Jinja filter.
