 "codebook": "## Reading the results\n\nEach row is an event, with its date precision and status at that event. Publication, national transposition deadlines and legal application are distinct; a deadline does not establish that every country completed adoption. [@etsi-2014-en-301-549-v1; @ada-2010]\n\nA historical published row does not establish that an edition is still current. First-day dates marked month or year do not assert an exact day. Public abstracts and previews do not provide the full paid requirements. [@iec-60118-4-1981; @iec-60118-4-2014]\n\nDraft schedules and targets remain qualified: BSI's project stage-start dates are plans, not evidence of completed stages. [@bsi-60118-17-project]\n\n## Compilation and interpretation\n\n`standards-timeline.csv` contains 61 selected events supported by 37 library sources, reviewed on 2026-10-13. It covers the standard families named in job q19, plus infrared transmission, loop components and maintenance, New York City law, Canadian building provisions and British bus requirements.\n\nOne row represents an event for an instrument: publication, adoption, an application date, consultation or withdrawal. Amendments and their consolidated edition share a row when their dates match. A later publication can support an earlier event when its explicit history is the evidence. The `source_locator` identifies that history or the relevant clause.\n\n\nThe CSV is UTF-8, comma-delimited, with a header and standard double-quote escaping. Dates and citations should be imported as text. Rows are sorted by normalized date, instrument and event type; rows with month or year precision cannot establish a precise sequence within that period. There are no formulas, merged cells or presentation formatting.\n\nPublication, national adoption and legal application dates are different events. The timeline does not treat a new edition as a requirement to replace every existing installation. `withdrawn` is used only for directly evidenced, dated withdrawals; supersession alone is not assigned an invented withdrawal day. A historical `published` row therefore needs its limitations and later events to be interpreted correctly.\n\nIEC 60118-17 is still a draft in the material read. The April–June 2026 entries are BSI's national public-comment dates. Its November 2027 publication target is recorded only in a limitation, not as an accomplished future event. The 2026-10-13 row is an observation of an undated listing. Publication targets, national transposition deadlines and undefined project dates are not silently converted into completed milestones.\n\nCoverage is selective rather than a complete register of every national adoption, correction or local amendment. Paid text is represented only by what was readable in public abstracts and previews. The q19 research report lists gaps, archive provenance, existing-record concerns and useful findings for other questions. No new question or translated question summary was created.\n",
