Earlier baustein B (`07c653c`) added a 6-row Research-Alignments table
+ a "what's new" banner, but only surfaced ~75 % of what the four
Java-scan + literature-integration commits (`f854f0e`, `979f30c`,
`e8a118f`, `8daee1b`) had introduced. This commit closes the gaps
identified in the lückenprüfung:
Research-Alignments table grows from 6 → 10 rows
─────────────────────────────────────────────────
* +quasi-isothermic maps (Phase 10e, Java port — 6 classes incl.
discrete Beltrami-field solver, Lawson correspondence ~800 lines)
* +higher-genus + hyperelliptic surfaces (Phase 10b — `HyperellipticUtility`
+ Bobenko–Bücking 2009)
* +Möbius centring as variational problem (Phase 9d.4 — replaces the
iterative Fréchet-mean fallback in `normalise_hyperbolic()`)
* +Boundary-First / interactive flattening row (Crane 2017 BFF; Stripe
Patterns 2015) — listed for comparison even though it is not on the
porting roadmap, so the reader sees we know about it
* table caption clarifies that some rows are RESEARCH-only (no Java
parent) and some are planned ports
"What's new" banner
───────────────────
* citation count corrected from "+9" to "+13" — the four Tier-2 papers
added in commit `e8a118f` (Springborn 2019, Springborn–Veselov 2015,
Crane 2017 BFF, Bonneel et al. 2015 Stripe Patterns) are now named
* phase count of "+6 phases" kept, but +Phase 9d.4 (Möbius centring)
and +Phase 10e (quasi-isothermic) are now called out explicitly so
the reader knows what is in the count
* cross-link to `java-parity.md` for the reverse table (every Java
class → C++ destination or *do-not-port* rationale)
questions.md / Q1
─────────────────
* expand the table from 3 to 6 candidate phases — adding 10e (quasi-
isothermic), 10b (hyperelliptic), and 9d.4 (Möbius centring) as
options alongside the existing 9d.2 / 9f / 10c+10c′
* track column distinguishes RESEARCH-only from planned-port
* +Question C — "is there a seventh line we are missing?" — invites
the reader to flag a research thread we have not scoped yet
Pages hub will be refreshed to v5 in a follow-up step (separate from
the in-repo commit, lives only on the codeberg `pages` branch).
