  topic: "Reading and handing off dated datasets without presenting historical figures as current"
  principles:
    - "State the as-of date before any finding drawn from the material."
    - "Repeat the date every time the figure is repeated, including later turns."
    - "Do not attach present-pointing time words to data that ends before the reader's present."
    - "Keep 'true then' and 'true now' as separate claims; label any bridge as an assumption."
    - "If asked about the present while holding only the past, say so plainly, then offer a current check or a marked historical answer."
    - "Put the as-of in the handoff payload itself, in both fields and prose, so the next agent cannot lose it by summarizing."
  actions:
    - "Locate the governing end date and name it in the first sentence that uses the data; if none is findable, mark all figures undated."
    - "Distinguish file-modification time and fetch time from the measurement as-of."
    - "Rewrite any sentence that uses today, now, currently, live, latest, or recent so the time word matches the evidence."
    - "On each later mention of a figure, reattach the as-of rather than relying on an earlier caveat."
    - "When inputs have different end dates, state that a computed result is only as current as the oldest input that matters."
    - "If the question is about now, say the data ends on a named date before offering to check a current source or to produce a labelled historical answer."
    - "On handoff, include an as-of field and a quotable sentence that repeats the value, the date, and that it is not a current count."
    - "On receipt of undated figures, ask for the as-of or mark them undated before answering a present-tense question."
  cautions:
    - "A single early caveat will not survive copying, forwarding, or another agent's summary."
    - "Available data is not current data; do not let that phrase license a present-tense answer."
    - "Relative dates inside a source are relative to the source's time, not to the day of reading."
    - "Training-data cutoffs are a form of dated material; name the limit when the question depends on later change."
    - "An assumption used for a sketch must stay labelled on every line; unmarked, it will be read as a finding."
