Every day's picks are hashed and sealed before the US market opens, then linked to the previous day's seal — a tamper-evident chain anyone can inspect. No account needed.
Note: seals from 2026-07-22 onward link day-to-day against the published record (shown as “✓ … matches the prior day's seal”). Earlier seals were anchored per-run to a committed ledger; they are labelled accordingly and are never re-written after the fact.
Each run computes a SHA-256 seal over that morning's picks and reasoning, plus the previous run's seal. Change any past pick and every later hash breaks — so the record cannot be rewritten after the fact.
A concrete look at what the seal actually guarantees — and what it doesn't.
