What we deliberately don’t cite
- · Commercial data aggregators that lack primary-source attribution chains.
- · Property-portal listing-tier estimates (real-estate-agent quoted price guides aren’t primary).
- · Forecasts from individual analysts whose methodology isn’t public.
- · Anecdotal claims from buyer-agent newsletters or property-investing influencer accounts.
- · Our own back-tested predictions, until they’ve been graded held / missed / pending in the public ledger.
See /methodology for how each source feeds into the 49-metric scorecard, the citation chip mechanic, and the 5 confidence states. See /ledgerfor how propautopilot’s own predictions get held / missed / pending grading.
