United Kingdom pipeline — country #19, 6/6 extracted, 0 stubs

[bdevloed]

The first post-Brexit register in the corpus, and the first where both of the usual spines are unavailable: the UK is no longer in the EU GI scheme (Sussex, registered 2022, was never an EU registration), and Bétard 2022 is an EU PDO layer carrying no PDO-GB-* geometry. Both are replaced by UK-domestic sources.

Corpus

6 registered wine GIs — 4 PDO (English, Welsh, Sussex, Darnibole) + 2 PGI (English Regional, Welsh Regional). Every one ships a public product specification, so the UK is the only country with no stub tier, no national-spec fallback layer and no WAF bootstrap.

Sources

Spine (gb/00): the GOV.UK protected food and drink names register, via the site's own search + content API. The register publishes no GI file number, so stage 00 bridges slug → PDO-GB-* against the EU register. A 7th name (The Crouch Valley) is still an application and is filtered out.

Specs (gb/01 → gb/02): 5 PDF + Sussex's .docx, in three unrelated layouts handled by _lib/gb/spec.py — defra-pfn-2011 (PART blocks + upper-case VINE VARIETIES), defra-pfn-application (Darnibole, no link section so terroir falls back to the demarcated-area definition) and uk-gi-single-document (Sussex). Roster parsing rejoins PDF line-wraps by run (so Blau\nPortugueser stays one variety) but splits bulleted one-per-line rosters, and classifies prose out by item shape. Two source typos are repaired structurally because they split a name before any alias could apply.

Geometry: ONS Open Geography (OGL v3.0). Areas verified against published figures — England 130,522 vs 130,279 km²; Wales 20,790 vs 20,779; Sussex 3,788 vs 3,782. Brighton and Hove is unioned in deliberately: without it the Sussex coastline has a hole.

Darnibole

A 5 ha single vineyard with no published polygon anywhere. Its spec defines the area narratively but ships an OS/RPA parcel plan, and those 4-digit parcel numbers are National Grid references (easting/northing in 10 m units within the km square). The boundary is reconstructed from them — 6.1 ha against a declared 5 ha, no fudge factor — and anchored three ways: internal N/S+E/W consistency (including a km-line visible on the plan), an EU-DEM transect confirming a ~13 % south-facing slope above a valley floor at 11–14 m, and the ONS centroid of the vineyard's postcode 502 m away. The panel discloses it as approximate; see _lib/gb/darnibole.py.

• grape lexicon: 7 UK varieties (Cascade, Madeleine Angevine/Sylvaner, Roter Veltliner — distinct from Frühroter — Frühgipfler via its synonym Senator, Triomphe d'Alsace, Gagarin Blue) + Blau Portugueser / Elbling White aliases. VIVC ids verified.
• fix(map): grape pills showed another country's spelling. emit_html dropped a record's own name whenever it matched its slug, and the client fell back to the most frequent spelling corpus-wide — so English "Optima" rendered as Germany's "Optima 113", German "Müller Thurgau" as Hungarian "Rizlingszilváni", Spanish "godello" as Portuguese "Gouveio". 1,047 substantive cases across 10 countries.
• fix(it): tarantino and rotae were bound to the wrong appellation's Wikipedia article (Trentino, Roma) — and rotae shipped a wiki-sourced terroir bullet about the Roma DOC in all four locales. Both pinned missing; 02d/02e re-run.
• audit_terroir_facts: wire GB in, and make unsupported countries an explicit counted skip instead of a KeyError swallowed as a corrupt cache (it silently covered only FR/ES — 1,030 records across 18 countries).
• geometry-outlier whitelist for the four national GB records (Isles of Scilly, Anglesey); WineGB as the England/Wales trade body.

Verification

368 tests (16 new GB parser tests), ruff clean, eslint 0 errors, duplicate-key audit clean, audit_gb_coverage --strict passes. Rendered and visually checked in a browser at all four locales. Deployed and smoke-tested live.
