# Timeline performance sample

## Verification Boundary

This suite measures real timeline reads under fixture volume; it is registered as integration evidence.

## What This Suite Proves

Fixture-volume timeline reads are timed against the real database. This is a performance sample without a functional acceptance binding.

No capability or feature scenario is bound to this suite. Its executable assertions remain engineering evidence until a precise acceptance mapping is reviewed.

## What It Does Not Prove

It does not establish deployed Lambda transport, live Platform policy or end-user browser behavior.

## Real Dependencies and Test Doubles

The actual persistence or presentation functions execute against the migrated PostgreSQL database and fixture execution contexts.

## Must Not Be Doubled

The database queries, constraints, version checks, workspace policies and transaction boundaries under assertion remain real.
