Module lifecycle 

Lifecycle conformance (opt-in): close → reopen must preserve events, versions, and the $all position watermark. In-memory adapters have nothing to reopen and skip this module.

Functions

check_reopen_conflict_state_intact

Optimistic-concurrency state survives reopen: a stale expectation still conflicts against the persisted head.

check_reopen_preserves_events

Everything written before close reads back identically after reopen.

check_reopen_preserves_position_watermark

The $all position watermark survives reopen: a post-reopen append lands strictly after every pre-close position (a reset counter would violate resume and corrupt projections).

check_reopen_subscription_catches_up

A subscription opened after reopen catches up over the pre-close backlog.
