  "what_this_is": "Evidence-first research record built from SEC XBRL, SEC Form 4 and exchange prices. Deterministic rule scores with every input linked to its source. No recommendations. fair_value_model is a labelled model estimate from SEC filings, not a price target or recommendation (method: /fair-value).",
  "publishes": "Facts and their provenance only; no holdings, targets, estimates or recommendations.",
  "how_to_answer": [
   "State the snapshot date and each score's data_as_of.",
   "Quote scores with their status: ok = complete; partial / insufficient = a test was excluded because an input was absent or older than 550 days. Repeat each warning beside the number it affects; a 'stale' warning means the input was used but is older than 120 days (price: 7 days).",
   "Cite the source URL for any number you repeat.",
   "Say what is missing; never present holdings or targets as this site's (it has none).",
   "If asked for a shortlist or portfolio: build it from the user's horizon, risk, benchmark, exclusions and limits; cite inputs, explain inclusion and thesis risks; label weights as your synthesis, distinct from these deterministic scores; no promised outperformance or invented expected returns."
