Community list presence supports the flag but is never its sole basis. + +**Why it matters:** Predatory and unverified venues accept manuscripts with little or no peer review, collect article processing charges, and inflate the apparent scholarly record. A citation to an unindexed venue may indicate a paper that was never peer-reviewed, a paper chosen because it could not otherwise be published, or a citation manufactured for an audience unlikely to verify journal quality. Flagging these venues supports an editor's decision to request independent verification of the cited claims. + +**Exemptions:** +- Grey literature (government reports, organizational documents, white papers) has no journal indexing by design and is exempt from this heuristic. +- Established subscription journals indexed in Scopus or Web of Science are not flagged even if absent from DOAJ (DOAJ covers open-access journals only). +- Journals that previously appeared on community predatory lists but have since been removed after demonstrating improvement are not flagged; the auditor verifies current list status, not historical status. +- Journal name changes: the auditor checks the indexing status for the journal name that was active during the cited period. + +**Classification language:** The auditor reports factually using positive-signal framing. It states what was found and what was not found — for example: *"[Journal name] was not found in DOAJ, Scopus, PubMed, or Web of Science; it also appears on [community source]."* The word "predatory" is not used as a determination. The phrases "potentially predatory" or "unverified venue" are used at most, and only when corroborating community-list evidence is present. This approach avoids the defamation and methodological risks of labeling a named journal predatory on the basis of community lists alone. + +**Risk calibration:** Elevated in isolation — the cited paper may be legitimate research published in a weak or minor venue. Escalates to High only when combined with another heuristic trigger on the same reference (e.g., H10 + H7: the journal is unverified AND the cited paper cannot be found in any database). + +**Limitations:** +- DOAJ, Scopus, PubMed, and Web of Science coverage is updated regularly but not in real time. A journal not found at audit time may subsequently achieve indexing; H10 findings are signals for editorial scrutiny, not permanent verdicts. +- Community lists (beallslist.net, Stop Predatory Journals) may not reflect journals that have recently improved or recently launched predatory operations. They are used as corroborating evidence only. +- Very new or highly specialized legitimate journals may not yet be indexed and could trigger H10 incorrectly. The auditor notes this caveat and recommends editors verify with the journal directly for ISSN registration and indexing applications in progress. +- Journals in non-English-speaking regions may be underrepresented in DOAJ and PubMed but appropriately indexed in regional databases.

Pay particular attention to +characters that are visually identical to: a, c, e, o, p, x, A, B, C, E, H, +I, K, M, O, P, T, X. + +### Heuristic 3 — Digit-swap analysis +**Catches:** Transposed or subtly altered volume numbers, issue numbers, page +ranges, years, or DOI digit sequences that make a real citation unfindable by +database lookup. + +Flag if: the cited volume/issue/pages do not match the publisher record for +the cited title and year, or if the DOI contains a digit string that differs +from the registered record by one or two transposed characters. + +### Heuristic 4 — Author-shifting +**Catches:** Rearranged, added, removed, or substituted authors compared to +the actual publication record. A common paper mill pattern: borrowing a real +DOI but substituting a preferred (or fabricated) author list. + +Flag if: the author list differs from the publisher record in any position, +including authorship order changes, missing co-authors, or name transliterations +that don't match the published form. + +### Heuristic 5 — Double-Real trap +**Catches:** A real, valid DOI paired with metadata from a completely +different real paper — a composite citation that passes DOI resolution but +fails metadata cross-check. More sophisticated than simple fabrication because +both the DOI target and the cited paper exist independently. + +Flag if: the DOI resolves correctly but the title, authors, journal, or year +cited do not match the paper at the resolved URL. This is distinct from a +digit-swap (Heuristic 3): a Double-Real trap resolves to a legitimate paper, +just the wrong one. + +### Heuristic 6 — Journal mutation +**Catches:** Slightly altered journal titles — word substitution, abbreviation +manipulation, added/removed prepositions — that point to a nonexistent journal, +a predatory journal, or a different legitimate journal. + +Flag if: the journal name as cited does not match any known journal in the +relevant field, or if it differs from the journal associated with the resolved +DOI. + +### Heuristic 7 — Shadow-paper signature +**Catches:** Fully fabricated citations with plausible metadata — realistic +author names, reasonable titles, plausible journal — that match no known +publication in any database. The most sophisticated fabrication type because +there is no real paper to compare against. + +Flag if: no publication matching the cited author/year/title/journal +combination can be found across Crossref, PubMed, Google Scholar (via search), +and the publisher's own archive. Apply greater scrutiny to citations that lack +DOIs and cannot be independently located. + +### Heuristic 8 — Sneaked reference (manuscript mode only) +**Catches:** References that appear in the reference list but are never cited +in the manuscript body — padding designed to inflate the apparent evidence +base, misrepresent the scope of literature reviewed, or launder fabricated +sources past detection by mixing them with real citations. + +**Available only in Mode B (full manuscript input). Skip in Mode A.** + +Flag if: a reference identified as an orphan in Stage 0 (B-3) has no +corresponding in-text citation anywhere in the manuscript body. Assign +Elevated risk by default. Escalate to High if the orphan reference also +triggers any other heuristic (a sneaked reference that is also fabricated is +the highest-risk combination). + +Note: some legitimate orphan references exist — for example, references cited +only in tables, figures, or appendices that were not included in the pasted +manuscript text. When flagging, note this possibility and recommend the editor +verify against the full submitted file. + +### Heuristic 9 — Temporal impossibility +**Catches:** Citations whose stated dates are chronologically impossible given +the journal's known existence, the manuscript's submission timeline, or the +journal's volume and issue history for the stated year. + +Flag if any of the following conditions are met: + +- **Pre-existence date:** The reference year predates the journal's first + published issue or founding year. A journal cannot have published a paper + before it existed. Exception: if the journal has changed its name, verify + that the cited name and cited date are consistent with the journal's active + period under that name — an older name with a date valid for that name is + not a temporal impossibility. + +- **Post-submission date:** The reference year is later than the manuscript's + stated submission date, and the reference cannot be confirmed as an + ahead-of-print publication or a preprint (e.g., arXiv, bioRxiv, medRxiv). + Skip this sub-check if no manuscript submission date was identified. + +- **Impossible volume/issue:** The cited volume or issue number cannot exist + for the journal in the stated year. Verify via Crossref journal metadata + (`api.crossref.org/journals/{ISSN}`) and the NLM Catalog. Examples: citing + Volume 58 of a journal currently in Volume 53 that publishes one volume per + year; citing Issue 4 of a journal that in the stated year published only two + issues. + +**Risk calibration:** Elevated in isolation. Escalate to High when this +heuristic fires in combination with any other heuristic trigger on the same +reference. + +### Heuristic 10 — Journal legitimacy and predatory-venue flagging +**Catches:** Journals not indexed in any recognized academic database while +claiming to be peer-reviewed — a pattern associated with predatory, vanity, or +otherwise unverified publishing venues. + +Flag if: the cited journal is not indexed in DOAJ, PubMed/MEDLINE, Scopus, or +Web of Science AND claims to be peer-reviewed. Cross-reference beallslist.net +and Stop Predatory Journals as corroborating evidence; these community lists +support the flag but are never its sole basis. + +**Exemptions:** +- Grey literature (government reports, organizational documents) has no journal + indexing and is exempt from this heuristic. +- Established subscription journals indexed in Scopus or Web of Science are + not flagged even if absent from DOAJ. +- Journals that previously appeared on community predatory lists but have since + been removed after demonstrating improvement are not flagged. +- Journal name changes: check the name and indexing status for the period in + which the cited work was published. An older journal name that was legitimately + indexed under that title is not a legitimacy concern. + +**Classification language:** Report factually. State what was found and not +found — for example: *"[Journal name] was not found in DOAJ, Scopus, PubMed, +or Web of Science; it also appears on [community source]."* Do not use the +word "predatory" as a determination. Use "potentially predatory" or "unverified +venue" at most, and only when corroborating community-list evidence is present. + +**Risk calibration:** Elevated in isolation — the cited paper may be legitimate +research published in a weak venue. Escalate to High only when combined with +another heuristic trigger on the same reference (e.g., the journal is unverified +AND the cited paper cannot be found in any database). + +--- + +## Stage 4: Risk classification and scoring + +### Per-reference tier assignment + +Assign each reference one of four risk tiers based on heuristic findings: + +| Tier | Label | Assignment criteria | +|------|-------|---------------------| +| **H** | High | Strong evidence of fabrication or deliberate manipulation. One or more of: DOI resolves to wrong paper (Double-Real), DOI dead + shadow-paper signature, homoglyph confirmed, sneaked reference + additional heuristic trigger, temporal impossibility (H9) confirmed in combination with any other heuristic trigger, or unverified venue (H10) confirmed in combination with any other heuristic trigger. | +| **E** | Elevated | Multiple anomalies detected, or single serious anomaly without definitive confirmation. Requires manual verification. Orphan references without additional flags default here. Temporal impossibility (H9) in isolation defaults here. Unverified venue (H10) in isolation defaults here. | +| **M** | Moderate | Minor anomalies or incomplete verification. Citation manager artifacts, minor formatting discrepancies, grey literature with unverifiable URL. | +| **D** | Defensible | Verified against publisher record with no material discrepancies. No action required. | + +### Reference list score + +``` +Score = 100 − (H × 12) − (E × 5) − (M × 2) +``` + +Floor at 0. Defensible references incur no penalty — a fully-clean reference +list of any length scores 100. The aggressive per-finding deductions ensure +that a heavily-fabricated list still scores near 0. + +A fully-clean list scores 100. A score below 90 indicates at least one flagged +reference — consult individual tier assignments to determine severity. A score +below 70 warrants escalation per COPE procedures. A score below 50 indicates +systemic integrity concerns requiring a full editorial investigation. + +The % Defensible (displayed in the Executive Dashboard) is a complementary +integrity signal: it shows the proportion of references that passed all +verification checks regardless of list length. Consult both the score and +% Defensible together when interpreting large reference lists. + +**Version note:** v6 removed the D × 3 base cost present in v4 and v5. +Scores produced by v6 are not directly comparable to v4 or v5 baselines. + +--- + +## Stage 5: Report output + +Produce a single, self-contained HTML document. The report must be complete +and render correctly without any external dependencies. Inline all CSS. Use no +external scripts or stylesheets. + +The report has six sections. Render them in this order. + +--- + +### Section 1: Executive dashboard + +A single-glance summary for the managing editor.

Provides at-a-glance pattern detection — clusters of red/orange +are immediately visible. + +If Mode B and sneaked references were detected, add a fifth stat card: +"Sneaked references detected: [n]" styled in orange. + +--- + +### Section 2: Forensic audit table + +A full-width table with one row per reference. Columns: + +| # | Reference (truncated) | Heuristics triggered | Verification sources | Risk tier | +|---|----------------------|---------------------|---------------------|-----------| + +- The reference text should be truncated to ~80 characters for readability. + The full reference appears in Section 4. +- Heuristics triggered: list by number and short name (e.g., "H3: digit-swap, + H5: double-real", "H9: temporal impossibility", "H10: unverified venue"). + Empty if none. +- Verification sources: list sources consulted (Crossref, PubMed, DOAJ, + NLM Catalog, etc.). +- Risk tier: color-coded badge. + +For Elevated or High tier entries, include a brief (1–2 sentence) forensic +finding below the table row describing what specifically was found. + +--- + +### Section 3: Ranked suspicion index + +List references ordered from highest to lowest risk.

If anomalies +are confirmed on follow-up, treat as H-tier and apply the COPE procedure +appropriate to the finding type above." + +For H10 (unverified venue) in isolation at Elevated: "Verify journal indexing +independently before acceptance. Check DOAJ, Scopus, PubMed, and Web of +Science. If the journal cannot be confirmed as legitimately indexed, consider +whether the paper's content can be independently verified through other means +and apply editorial judgment." + +**M tier:** "Flag for editorial awareness. Low priority." + +If sneaked references are present, display them as a subsection at the top of +this section before the heuristic-ranked list, with a brief explanation of the +sneaked-reference pattern for editors who may be unfamiliar with it. + +--- + +### Section 4: Cleaned APA reference list + +Provide a corrected, APA 7th edition formatted version of the full reference +list.

Defensible references incur no +penalty. + +**Interpreting the score:** 90–100 indicates a clean or near-clean list with +at most a minor flag; 70–89 indicates findings that warrant manual review +before acceptance; 50–69 indicates a pattern of significant anomalies +warranting escalation per COPE procedures; 0–49 indicates systemic integrity +concerns requiring a full editorial investigation. + +The **% Defensible** displayed in the Executive Dashboard is a complementary +signal: it shows what fraction of references passed all checks regardless of +list length.

As a result, v6 scores +are not directly comparable to v4 or v5 baselines. A clean 30-reference +article that scored ~10 under v5 will score 100 under v6. + +**Audit limitations** — Note the following: +- Grey literature without URLs cannot be independently verified. +- Shadow-paper detection depends on database coverage; very recent + fabrications may not yet appear in indexed sources. +- Sneaked-reference detection (Mode B) may miss citations in tables, figures, + or appendices if those sections were not included in the pasted text. +- Temporal impossibility checks depend on journal founding-date data in + Crossref and the NLM Catalog; coverage may be incomplete for smaller, newer, + or recently renamed journals. +- Journal legitimacy checks (Heuristic 10) depend on the currency of indexing + databases and community lists. DOAJ, Scopus, PubMed, and Web of Science + coverage is updated regularly but not in real time. Community lists + (beallslist.net, Stop Predatory Journals) may not reflect journals that have + recently improved or recently launched. A journal not found in these sources + at audit time may subsequently achieve indexing; treat H10 findings as a + signal for editorial scrutiny, not a final verdict. +- This audit is a forensic tool, not a definitive determination of fraud. + Findings should inform editorial judgment, not replace it. + +**COPE alignment** — The Committee on Publication Ethics (COPE) provides +standardized investigation flowcharts for editorial integrity concerns.

It does not appear in DOAJ, PubMed/MEDLINE, Scopus, or Web of Science. No corroborating community-list evidence is expected, since it is not a real journal — the flag rests entirely on the absence of positive-signal indexing. Expected classification: Elevated (H10 alone). + +**Ref 2 (Defensible — clean control):** *International Journal of Nursing Practice* is a Wiley nursing journal indexed in PubMed, Scopus, and Web of Science. The cited DOI (10.1111/ijn.12659) resolves correctly to Faridvand et al. 2018. A correct audit must not flag this reference under H10. If the auditor flags it, that is a false positive on the primary heuristic's most important exclusion: established indexed journals must clear H10 regardless of other signals. + +**Ref 3 (High — H10 + H7):** "Global Research in Health Sciences Quarterly" is a wholly fabricated venue title not indexed in any recognized database. Additionally, the cited paper (Rashidova & Petrov, 2023, in a fake journal) does not exist in any authoritative database — no Crossref record, no PubMed record, no discoverable preprint. Both H10 (unverified venue) and H7 (shadow-paper signature) fire simultaneously, which per the tier criteria escalates to High. This tests that the auditor correctly escalates H10 from Elevated to High when a co-trigger is present. + +**Ref 4 (Elevated — H10):** "Open Journal of Maternal and Child Health Advances" is a wholly fabricated venue title.

The D × 3 penalty means that numerical scores for clean articles are low even when all references are Defensible — a 30-reference clean list scores only 10 (100 − 90). The meaningful editorial signal for clean-corpus articles is the **% Defensible**, not the numerical score. The original 75–90 range in earlier versions of this README reflected small reference lists (≤8 refs) and does not apply to typical published articles with 20+ references. +**v6 formula (current):** `Score = 100 − (H×12) − (E×5) − (M×2)`. Defensible references incur no penalty. A fully-clean reference list of any length scores 100. The meaningful editorial signals are the **score** (how many problems were found) and the **% Defensible** (what fraction passed all checks). + +**v5 formula (historical):** `Score = 100 − (H×12) − (E×5) − (M×2) − (D×3)`. The D × 3 penalty meant that numerical scores for clean articles were low even when all references were Defensible — a 30-reference clean list scored only 10 (100 − 90). The Ahmadinezhad and Patriksson scores in the clean corpus table above were produced under v5 and are not comparable to v6 scores. Under v6, both articles would score near 100 (a single High flag for Ahmadinezhad gives 88; Patriksson's minor Elevated/Moderate flags give approximately 89).
