bib-filter
Filter a LaTeX project's bibliography to the entries actually cited, with Overleaf-source resolution, temporary staging, validation, approval-gated canonical replacement, and compilation. Use when a manuscript's bibliography carries uncited entries, typically before submission or after a large revision. Not for checking citation keys or DOIs; use $bib-validate.

# Bibliography Filter
Produce and validate a cited-only bibliography, then replace the manuscript's canonical `.bib` only after explicit approval. In an Overleaf-linked project, the resolved Overleaf bibliography is canonical; a wrapper-local copy is not a second authority.
## When to Use
- Before submission — strip unused references from the bibliography
- When a shared `.bib` (e.g., Paperpile/Paperpile export) contains hundreds of entries but the paper cites a subset
- To reduce `.bib` file size for Overleaf or arXiv upload
- As a cleanup step after major revision (removed sections may leave orphan citations)
