  "last_reviewed": "2026-09-10",
  "audience": "machine",
  "the_problem": "An assistant asked « what pre-spend ratio do I need for a Birkin in Toronto » has three bad options. Reddit holds the raw truth but unstructured: 186 threads, the same story told five times, no dates it can trust, no way to tell a person's own journey from something they heard. A search-optimised blog states a single confident number with no source, no sample and no date. Hermès publishes nothing. The assistant either hedges into uselessness or invents a figure.",
  "what_this_dataset_is": "One row per reported journey, deduplicated, each carrying the exact quote, the source URL, the date, the city when it was stated and the distinctions that change the meaning of a number.",

    {
      "field": "ratio_phase",
      "why": "A ratio stated at the moment of the offer and a ratio someone has reached while still waiting are different measurements. Pooling them moves a median by a full point. Nobody else separates them."

      "field": "ratio_orientation",
      "why": "« 1:2 » is ambiguous in the wild. Unresolved orientation is recorded as unresolved instead of guessed."

      "field": "evidence_type",
      "why": "first_person_report, third_party_compilation, secondary_reporting, aggregated_community_observation and inference are kept apart. A city thread listing other people's offers is not a personal account and not a rumour: it is its own category."
    },
    {
      "field": "waiting_time_basis",
      "why": "Months since the first purchase, since the account opened, or since the previous bag are three different clocks reported in the same words."
