# Dated membership reads and workspace isolation

## Verification Boundary

Membership writes, dated reads, affiliations, standing and officer scope run against the prepared database.

## What This Suite Proves

The structured bindings identify the capability and feature cases whose reviewed assertions this suite executes. Source anchors preserve the evidence for each binding.

## What It Does Not Prove

A local pass does not qualify deployed scheduling, browser administration or successful production partner calls. Registration records existing code and leaves execution and conformance unverified.

## Real Dependencies and Test Doubles

The database constraints and workspace-scoped persistence exercised by this suite remain real; manual clocks, supplied callers and neighbor fixtures define the local boundary.

## Must Not Be Doubled

Keep the prepared database, workspace boundary, exercised owner constraints and the business operation under test real. A partner double cannot substitute for the Membership write this suite claims to exercise.
