DOI 10.1007/0-387-29555-0_13 is Ushijima (sole author) —
"A Volume Formula for Generalised Hyperbolic Tetrahedra",
in: Prékopa & Molnár (eds.), Non-Euclidean Geometries,
Springer 2006. arXiv: math/0309216.
The references.md entry was wrong on all three counts:
- Author: "Meyerhoff, Ushijima" → Ushijima only
- Title: "A Note on the Dirichlet Domain" → entirely different title
- Book: "The Epstein Birthday Schrift" → Non-Euclidean Geometries
Same error pattern as the Kolpakov-Mednykh fix: the Java source
links only to a DOI without naming authors; a wrong name was
invented during the C++ port.

arXiv:math/0603097 is Springborn 2008 ("A variational principle for weighted
Delaunay triangulations and hyperideal polyhedra"), not a Kolpakov-Mednykh paper.
The author pair Kolpakov & Mednykh has no joint publication from 2006; their
earliest collaboration is arXiv:1008.0312 (2010, on torus knots, unrelated).
The wrong author name was introduced during the Java→C++ port — the Java source
correctly links to math/0603097 without naming the authors; whoever ported it
invented "Kolpakov-Mednykh". The S1 citation audit (2026-05-31) then cemented
the error by adding the incorrect row to references.md.
Files corrected (7):
- code/include/hyper_ideal_utility.hpp
- code/include/hyper_ideal_functional.hpp
- code/tests/cgal/test_hyper_ideal_functional.cpp
- doc/math/references.md
- doc/roadmap/research-track.md
- doc/architecture/project-structure.md
- doc/api/tests.md
Also:
- doc/reviewer/math-derivation-citation-audit-2026-05-31.md: M1 post-correction noted
- doc/reviewer/finding-orchestration.md: lesson-learned section added (AI citation
audits can introduce plausible-but-wrong attributions; human expert review required
before CGAL submission)
- papers/MANUAL-DOWNLOAD.md: overview of papers requiring manual download (paywalled
journals, TU Berlin theses, books)
- .gitignore: papers/*.pdf excluded (downloaded arXiv PDFs, not tracked)

Session 1 (2026-05-31) resolved 26 findings across Sonnet/Haiku/Opus; 298/298
CGAL tests green. Bring the audit docs in line with reality:
- README.md: G0 banner now records that the original authors were contacted by
email about porting/relicensing rights (awaiting reply); headline-status cells
updated per finding; new "Session 1 — implemented" record; link to the plan.
- Per-audit resolution banners (api-performance, numerical-stability,
input-validation, test-coverage, math-citation, thread-safety) + G0-blocked
banners (cgal-submission, dependency-license).
- NEW finding-orchestration.md: the meta-plan mapping every finding to a session,
an implementing model (Haiku/Sonnet/Opus by the "how much must be understood"
rule), and an Opus review gate after each implementation session. Records S1
(done) and lays out S2–S6 so the next session can be picked up cold.
Docs only — no code change.

Checks code/docs against the published mathematics (vs java-port-audit which
checks code vs Java):
- M1: Kolpakov-Mednykh volume formula used in code but missing from references.md
- M2: BPS circle-packing paper cited as '2010' in code vs '2015' in references.md
- M3: post-2023/preprint citations back unimplemented phases — re-verify + clarify
scope before submission
- M4: no canonical citation-key convention
- M5: large derivations numerically validated but prose unreviewed — expert sign-off
