Citation Verification

Citation — stage 10

Make every author-used reference traceable, real, correctly identified, and honestly connected to the claim it is supposed to support. Treat formatting, metadata existence, publication-integrity facts, and semantic support as four different questions.

Read citation-resource-map.md before a full manuscript audit. Read references/registry_contract.md before producing or consuming the canonical registry. Read references/locator_audit.md before judging claim support.

Stage contract

• Consume paper-writing's light.paper_claims.v1, exact claim/source locators, current claim text hashes, reviewer-bound citation-support hashes, manuscript, figures/tables, supplement, and reference candidates.
• Reuse literature-search provenance as input evidence; independently verify the references the author actually keeps.
• Emit light.citation_registry.v1, BibTeX, CSL JSON, source-level evidence, failure records, claim-edge review, citekey audit, and light.findings.v1(producer=citation).
• Keep stage 10's only critical gate citation_verify: confirmed missing works and chimeric citations. Metadata conflicts, unavailable sources, claim relevance, formatting, and publication-update alerts are warn/skip.
• Fix citation failures inside stage 10. ROUTES has no key 10; never invent a back-edge.
• Hand references.bib, citekey-audit.json, registry and delivery.json to typesetting. Typesetting compiles and checks keys; it does not re-decide authenticity. delivery.json must declare status and per-deliverable sha256: hashes so typesetting can reject stale or edited handoffs.

Non-negotiable rules

1. Never invent a reference, DOI, author, year, venue, citekey, locator or support verdict.
2. Never call a network failure, rate limit, 5xx, authentication failure, or index miss “this work does not exist.”
3. Assign CONFIRMED-MISSING only when DOI Registration Agency explicitly reports non-existence and Crossref plus DataCite both return 404/410.
4. Assign CONFIRMED only when registration metadata and at least one independent field source confirm the work. Otherwise retain UNAVAILABLE or UNRESOLVED.
5. Preserve every source's title/authors/year/venue/identifier value. Select canonical fields from the registration agency; never use fuzzy matching to overwrite the original citation.
6. Treat a real DOI paired with conflicting title/authors/year as a possible chimeric citation. Multi-core-field conflict is critical; one ambiguous field mismatch is a warning for manual review.
7. Read publication updates in the correct direction: the affected original carries Crossref updated-by; the notice carries inverse update-to.
8. Record retraction/correction/expression-of-concern facts and alerts, then hand integrity judgment and wording to research-ethics. Do not rebuild its ethics gate.
9. Never equate metadata confirmation or “A cites B” with “B supports claim C.” SUPPORTS requires a locator-backed semantic review.
10. Keep the core path local/free or public/no-key. OpenAlex and keyed Semantic Scholar are optional coverage enhancements; commercial managers, institutional databases, and browser plugins are never required.

Execute the author workflow

1. Inventory every reference occurrence

Use the claim map, manuscript, figures/tables and supplement together:

python scripts/citation_registry.py \
  --claim-map claim_plan.json \
  --draft paper.tex \
  --figure figure_notes.md \
  --supplement supplement.md \
  --refs-spec citation_input.json \
  --out-dir citation-delivery

Preserve claim_id, exact claim, claim locator, artifact path, occurrence locator, citekey and raw identifier. Use templates/citation_input.json when the project has no reference spec.

2. Normalize without erasing versions

Normalize DOI, arXiv, PMID, ISBN and URL. Deduplicate exact works. Keep arXiv, accepted manuscript, versioned dataset and published DOI as explicit versions under one work only when the inputs establish the relationship. If not established, keep them separate and mark the relationship unresolved.

3. Verify with independent sources

python scripts/verify_refs.py \
  --spec citation_input.json \
  --self-author Smith \
  --out verify.json

Use Crossref or DataCite as the registration source. Use PubMed, Semantic Scholar, or configured OpenAlex as the independent field source. Keep each endpoint, HTTP status, outcome, timestamp and returned fields in source_evidence，并保存实际参与判定的 normalized-field SHA-256。Crossref polite-pool email、OpenAlex/Semantic Scholar key 只用于请求，绝不写入 endpoint、registry 或日志。

Interpret status exactly:

4. Resolve field conflicts and chimeras

Compare the author's cited title, authors and year against registration metadata. Inspect field_conflicts source by source. Keep the user's raw citation unchanged until a human resolves the conflict.

Treat these as chimeric critical:

• real identifier plus conflicts in at least two of title/authors/year;
• title matches but the cited author list adds an author absent from the registered work.

Treat a single title translation, subtitle, year-online/year-print difference, author omission or ordering issue as metadata warning unless corroborating evidence establishes a chimera.

5. Record publication updates

Inspect publication_updates. Confirm relation direction with both the affected work and notice DOI when the alert matters. Record type, notice DOI, source and direction. Send those facts to research-ethics; do not label a correction notice itself retracted because it has update-to.
