Frontend-testinfrastruktur (Vitest) -- geo, offline-queue, formats

Fortsetter robusthetslinjen: frontend-tester var eksplisitt utenfor
omfang i ADR-058/060. 30 nye tester: lib/geo.ts (GPS-avstand/retning,
fasit-forankret), lib/offline-queue.ts (regresjonsvern for
resourceKey-fiksen fra forrige runde), lib/ny-runde/formats.ts
(fullstendighetssjekk på tvers av format-listene). Egen, lettvekts
Forgejo Actions-workflow (ingen Docker-utenfor-Docker nødvendig).

To reelle funn underveis: prosjektet bruker pnpm ikke npm (et første
forsøk med npm feilet, ingen skade); pnpm-workspace.yaml var arvet-
ignorert fra V0-malen men har nå reelt CI-relevant innhold
(allowBuilds: sharp), rettet før det kunne feile CI stille. Se
ADR-061/CHANGELOG punkt 70.

+## ADR-061: Frontend-testinfrastruktur (Vitest) — 2026-08-10
+
+Direkte fortsettelse av ADR-058/060, som begge eksplisitt navnga
+frontend-tester som bevisst utenfor omfang. Bruker ba om å ta tak i det
+som neste steg i robusthetslinjen, nå som backend-testriggen og CI-
+runneren stod klare.
+
+**Beslutning A — Vitest, ren logikk-testing (`lib/**`), ingen
+komponenttester ennå.** Node-miljø, ingen jsdom/@testing-library i
+denne runden — det finnes ingen komponenttester å kjøre ennå, og
+`node`-miljø er raskere/enklere når det ikke trengs. Tre moduler valgt
+etter samme risikobaserte prinsipp som backend-rundene:
+- `lib/geo.ts` (`haversineMeters`/`bearingDegrees`) — ekte GPS-
+  avstandsmåling (ADR-048), fasit-forankret mot kjente geodetiske
+  verdier (Oslo–Bergen luftlinje, 1 breddegrad ved ekvator ≈ 111,2 km),
+  ikke bare selv-konsistente tall.
+- `lib/offline-queue.ts` — regresjonsvern for `resourceKey`-fiksen fra
+  ADR-060 selv: egen test beviser eksplisitt at to ulike ressurser som
+  deler samme URL IKKE lenger blander sammen versjonsnummer, og at
+  round_hole sin eksisterende bruk (ingen `resourceKey` satt) fortsatt
+  faller tilbake til url-basert nøkling uendret. `fake-indexeddb` gir en
+  ekte IndexedDB-implementasjon i test-miljøet — ikke en mocket
+  tilnærming til køen.
+- `lib/ny-runde/formats.ts` — fullstendighets-/konsistenssjekker på
+  tvers av format-listene (`FORMAT_TO_API`, `FORMAT_MAP`, `API_TO_FORMAT`,
+  `TWO_SIDED` m.fl.), direkte motivert av et tidligere kjent
+  ømtåelig-punkt (separate `play_format`-gatingsett i flere
+  frontend-filer, lett å glemme å oppdatere ett sted når et nytt
+  format legges til). Testene fanger spesifikt opp det TypeScript IKKE
+  gjør automatisk: `FORMAT_MAP` bygges med en `as`-cast som omgår
+  fullstendighetssjekk, og en vanlig array som `FORMATS` har ingen
+  kompilator-garanti for å dekke alle `FormatId`-verdier.
+
+**Beslutning B — pnpm, ikke npm.** Prosjektet bruker pnpm
+(`pnpm-lock.yaml`, Dockerfilens `corepack enable && pnpm install`) —
+et første forsøk med `npm install` feilet med en intern npm/arborist-
+krasj nettopp FORDI `node_modules` allerede var strukturert som et
+pnpm-lagret (`.pnpm/`-innhold), ikke fordi noe var korrupt. Ingen skade
+skjedd (bekreftet med `pnpm install --frozen-lockfile`, som validerte
+hele treet på nytt), men en påminnelse om å sjekke lockfile-typen FØR
+man antar npm er riktig verktøy.
+
+**Reelt funn, rettet i samme runde:** `frontend/pnpm-workspace.yaml` var
+ignorert i `frontend/.gitignore` (arvet fra den opprinnelige V0-sandbox-
+malen, der fila kun inneholdt V0-interne sandbox-detaljer). Filen fikk
+nå reelt, deploy-relevant innhold (`allowBuilds: sharp: true`, fra
+`pnpm approve-builds` — uten den feiler `pnpm install` i et rent
+miljø/CI med `[ERR_PNPM_IGNORED_BUILDS]`). Ignore-regelen fjernet,
+fila sporet i git — ellers ville CI feilet på akkurat denne
+installasjonen hver eneste gang, usynlig lokalt siden node_modules
+allerede var godkjent på denne serveren fra før.
+
+**Beslutning C — egen, lettvekts CI-workflow, ikke gjenbruk av backend-
+sin.** `.forgejo/workflows/frontend-tests.yml` trigger kun på
+`frontend/lib/**`/`package.json`/lockfile-endringer, bruker
+`actions/setup-node@v4` (Node 22, matcher Dockerfilen) + `corepack
+enable` + `pnpm install --frozen-lockfile` + `pnpm test` — INGEN
+Docker-utenfor-Docker, ingen `docker.sock`-tilgang nødvendig, siden
+denne suiten ikke rører database eller containere i det hele tatt.
+Enklere og tryggere blast-radius enn backend-workflowen.
+
+**Verifisert:** 30 tester, 3 filer, alle grønne lokalt
+(`./node_modules/.bin/vitest run`, og via `pnpm test` etter
+`allowBuilds`-fiksen). Ingen produksjonskode endret -- ren
+testinfrastruktur.
+
+**Bevisst utenfor omfang:** komponenttester (jsdom/@testing-library),
+og en tilsvarende fullstendighetssjekk PÅ TVERS AV `round-detail.tsx`/
+`scorecard.tsx`/`leaderboard.tsx` sine egne, separate
+`play_format`-gatingsett (kjent ømtålelig punkt, men disse er store
+komponentfiler som ville krevd en helt annen testtilnærming enn ren
+lib-import — egen, fremtidig vurdering).
+
 Disse må avklares før eller under de relevante fasene:
