Time-travel read: the instance as it stood at the at watermark, reconstructed by folding its structural events. Property values that were marking-redacted or truncated in the event log surface as sentinel objects, not values.

The durable identity that survives every membership transition — upgrade, downgrade, freeze, cancellation, renewal. One per primary member; dependents (spouse, children, registered companions) attach under it as separate membership rows (commit 2). Distinct from the individual access-bearing membership because the account identity is what the operator tracks for billing (one subscription per account in commit 3), recognition (the long arc of the member-property relationship), and clinical-record binding (assessments attach to an individual membership, but the family unit lives on the account). The Mindbody Premier factoring of Pricing Option vs Membership vs Autopay vs Contract is the load-bearing reference for why account and access record are separate primitives.
