Finding-U3 from doc/reviewer/usability-audit-2026-05-31.md.
Three concrete errors corrected:
1. check_gauss_bonnet() row (was: implies all map types work)
→ now: 'EuclideanMaps/SphericalMaps only' — HyperIdealMaps overload
is = delete (compile error since external-audit Finding-B fix)
2. enforce_gauss_bonnet() row (same issue)
→ same restriction note added
3. newton_hyper_ideal() preconditions (was: 'lambda0 initialised')
→ WRONG: HyperIdeal computes lengths from b_v, a_e via zeta functions
internally; lambda0 plays no role. Correct precondition:
'no lambda0 needed · no GB pre-check'
→ Added explanation: strictly convex energy (Springborn 2020 Thm 1.3)
→ Newton converges for any targets without a pre-check
Gauss-Bonnet prose section also updated:
- Examples now show EuclideanMaps/SphericalMaps explicitly
- HyperIdeal compile-error note added with the correct hyperbolic
identity Σ(2π-Θ_v) - Area = 2π·χ and why no pre-check is needed
- Open-mesh note added (GB identity does not hold for boundary meshes)

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)
