Note systemic side effects of prophylactic intracoronary vasodilators ...

Add Rezkalla et al. 2017 (JACC: Cardiovascular Interventions) as a
verified citation for the drawback, in both the Japanese draft and the
English Introduction section.

Refine Introduction wording and add two more verified citations ...

- Add wang2026 (USCNet) and hibi2013 (IVUS history review) to
  references.bib after reading the full PDFs; cite them for KSCNet's
  originating kidney-stone-classification architecture and for the
  claim that IVUS can visualize vessel wall/plaque condition,
  respectively.
- Drop "microvascular spasm" as a contributing factor from the
  no-reflow definition, trim an editorializing clause after the
  attenuated-plaque finding, and rephrase the IVUS-focus sentence as
  the paper's own rationale rather than a general background claim.
- Remove the unsupported vasodilator-treatment-limitations sentence
  and the citation-needed marker on preventive-measures (distal
  protection devices/prophylactic vasodilators), per review: none of
  the added source papers support the former, and the latter is
  standard clinical practice not requiring a citation.
- Generalize the poor-prognosis sentence (previously citing specific,
  unsupported outcomes) to a claim not requiring a citation.

Wire up references.bib and verify citations against source PDFs ...

- Add citations/ folder holding the cited papers' PDFs (babapoor2022,
  wu2011, nishi2021), documented in CLAUDE.md so cite keys can be
  filled in/verified directly from the source paper instead of guessed.
- Fill in references.bib entries for all three keys with real
  bibliographic data, and drop a stray "@TODO" in the header comment
  that was making bibtex misparse the file as a malformed entry.
- Switch main.tex from the template's placeholder internal
  bibliography to \bibliography{references}, so citations actually
  resolve (previously rendered as undefined/"?").
- Correct the Introduction's babapoor2022/wu2011 citation claims after
  reading the full papers: babapoor2022 reports separate no-reflow
  (17.1%) and slow-flow (12.9%) rates in a single-center primary-PCI
  cohort, not a general "10-20% of PCI patients" figure; wu2011's
  finding is specific to AMI patients and a composite no-reflow/
  slow-flow (TIMI <=2) endpoint, and only the amount (not presence) of
  attenuated plaque differed significantly.

Draft Introduction via ja-drafter/review/translate pipeline ...

Writes sections/1_introduction.tex through the documented workflow:
Japanese draft (drafts/ja/1_introduction.md), fact-check + content
review against the Notion source of truth, then English translation.
Centers the section on the proposed KSCNet architecture; open claims
without a source yet are left as inline [citation needed] markers.
Also documents the pipeline itself in CLAUDE.md.

Number section files to match reading order ...

sections/*.tex renamed to 1_introduction.tex .. 6_conclusion.tex so the
directory listing sorts in the same order they're \input from main.tex.
No 0_abstract.tex: the abstract must stay inline in main.tex (mdpi.cls
reuses it as PDF pdfsubject metadata, which \input breaks), and a
drafting-only file would just duplicate it with a risk of drifting out
of sync, so CLAUDE.md now says so explicitly.
