alva/felsokning/services/gemensam/metodiker.mjs

// Metodikbiblioteket — delad kod.
//
// Låg tidigare bara i klienten, vilket gjorde att servern inte kunde
// utvärdera kvalitetsgrindens metodikrader (QUALITET C-2). Datan bor nu
// här; app/src/felsokning/metodiker.ts återexporterar den med typer, så
// det finns fortfarande exakt en sanning.
//
// En metodik är inte en checklista över vad som brukar vara fel — det
// vore att gissa åt teknikern. Den är en ordning för att utesluta:
// symptomet verifieras först, sedan det billiga och synliga, sedan det
// som kräver mätning, sist det som kräver demontering.
//
// Tre regler gäller alla metodiker här:
//
//   1. Varje kontroll har ett minimikrav (mätvärde, foto eller
//      observation). En kryssruta är inte evidens.
//   2. Symptomsteget frågar aldrig "vad är fel" utan "vad händer, när,
//      var". Kundens ord blir ett verifierat symptom först när det
//      reproducerats.
//   3. Där arbetet kan skada någon kommer säkerhetssteget först och kan
//      inte hoppas över — se HÖGVOLT.
//
// Att "täcka allt" går inte att lova. Det som går är att täcka fordonets
// system systematiskt och låta GENERISK vara ett strukturellt komplett
// skyddsnät: den fungerar även för det ingen förutsett.
//
// ---- Språk och granskningsstatus (ALVA-SPEC-060) ------------------------
//
// Texten är skriven på svenska och översatt till engelska när engelska
// blev källspråk. Det är alltså en ÖVERSÄTTNING som ännu inte lästs av en
// fackman på målspråket, och den ska behandlas som en sådan tills den är
// det — samma krav som ställs på de nio andra språken.
//
// Det spelar roll här och ingen annanstans i produkten: det här är den
// enda text i systemet som säger åt någon vad den ska göra med ett
// fordon. "Mät och dokumentera spänningsfrihet före ingrepp" är inte en
// etikett.
//
// NYCKELORDEN är ett undantag och är avsiktligt tvåspråkiga. De matchas
// mot teknikerns egen fritext; att byta ut de svenska mot engelska hade
// gjort metodikvalet blint för allt en svensk verkstad skriver. Fler
// nyckelord kan bara ge fler träffar, aldrig färre.
