## 4 — Recommended order of work
1. **Port `make_lawson_square_tiled()`** (low-level half-edge; see §5) →
unblocks the single HIGH oracle and the MED branch-point variant in one go.
2. Add `HyperIdealLawsonGoldenJava` test using the **per-class symmetric**
assertion above (robust, no DOF-order matching).
3. Add `wente.obj` asset → genus-1 uniformization self-consistency (MED).
4. Defer LATER items to their phases; revisit golden vectors then
(branch-point and hyperelliptic golden u\* are already recorded in the
Java tests and can be reused verbatim once the generator exists).
1. **DONE (PR #29)** — Tier 1: cyclic φ oracle + full analytic edge-DOF Hessian.
2.**DONE (PR #30)** — Tier 3: `make_lawson_square_tiled()` (low-level
half-edge; §5) + plain & branch-points golden oracles (per-class symmetric,
no DOF-order matching needed).
3. ⏸️ **Deferred** — Lawson **hyperelliptic** variant (XML-format reader +
`HyperIdealHyperellipticUtility` / jReality θ; non-symmetric golden).
4. ⏸️ **Phase 9f** — Wente genus-1 uniformization (quad/cyclic pipeline).
5. **Phase 10a/10c/11/13** — LATER items (genus-2, holomorphic forms, Schottky);
golden u\* / data recorded in the Java tests for reuse then.
