Finding-A from doc/reviewer/external-audit-2026-05-30.md. Root cause: both the Java reference (HyperIdealFunctional.java:222-231) and the C++ port silently applied the one-ideal-vertex volume formula to the first ideal vertex found in a face, ignoring any additional ideal vertices. For two or three ideal vertices this produces a wrong energy value with no diagnostic. Fix: add an ideal_count guard at the top of face_energy() that throws std::logic_error for ideal_count >= 2. The one-ideal (Kolpakov-Mednykh) and zero-ideal (Meyerhoff/Ushijima) paths are unchanged and correct. Three new GTests cover the three guard cases: MultiIdealGuard_TwoIdealVertices_Throws (two ideal → throw) MultiIdealGuard_AllThreeIdealVertices_Throws (all ideal → throw) MultiIdealGuard_ExactlyOneIdeal_DoesNotThrow (one ideal → no throw) 262/262 CGAL tests pass, 0 failed.

Reviewer meeting materials
A single landing page for the three documents associated with an external-reviewer meeting. The materials are written for a peer who actively publishes in discrete differential geometry — specifically the decorated-DCE / Penner-coordinates / hyperideal-polyhedra / canonical-tessellations research line — and who would potentially use conformallab++ as numerical infrastructure for their own future experiments.
| Document | Audience | Purpose |
|---|---|---|
briefing.md |
the reviewer | one-page orientation: what the project is, where to look first, what we want from them |
questions.md |
the reviewer | the 5 concrete decisions we want their opinion on (skim before the meeting) |
agenda.md |
me | my own meeting playbook: timing, order, the "no" question, post-meeting memo template |
After the meeting, a fourth file 2026-XX-XX-meeting-notes.md should
land here too — the memo template at the bottom of agenda.md is the
suggested structure.
When to send to the reviewer
- briefing.md + questions.md: as part of the meeting-confirmation email, ~5 business days before the meeting. Subject line: "Pre-read for our conformallab++ chat (~15 min)".
- agenda.md: never send. This is internal scaffolding.
Hub-Page durability
The reviewer hub HTML at https://tmoussa.codeberg.page/ConformalLabpp/
is published from doc/reviewer/hub.html in the repo (not from a
detached preview branch). This means:
- Merging any of the open PRs into
maintriggers.gitea/workflows/doxygen-pages.ymlwhich republishes the hub alongside fresh Doxygen HTML — the reviewer URL stays live across merges with no manual intervention. - The hub is source-controlled, so changes are reviewable via PR like any other doc, and old versions live in git history.
- The original Doxygen index moves to
/doxygen.htmlwhenever the hub override is active; both are reachable from the hub itself.
Quick links the reviewer should bookmark
- 🌐 Reviewer-hub landing page: https://tmoussa.codeberg.page/ConformalLabpp/ (the hub shows status badges, a "what's new" banner with the most recent delta, the research-alignment table, and direct links into every document below)
