Demo160 — Context Memory

Prepare the demo

Start at the root of the complete distribution built in Release. Shared projects Maf.Memory and Maf.DemoConnection are required. Answers use live chat without embeddings. Local read, reset, forget and save commands need no generated answer. Demo170 calls chat directly for its comparison.

• Installation and initial setup

• Connections and capabilities

Launch from the root

dotnet run --project demos/Demo160_ContextMemory/Demo160.App.csproj -c Release --no-build

Modes and procedure

Repeat Demo150’s correction and forgetting sequence, then ask a question without key=value. Inspect mem after each call and after forget module.

protected override async ValueTask StoreAIContextAsync(InvokedContext context,
    CancellationToken cancellationToken = default)
{
    if (context.InvokeException is not null)
        return;
    foreach (var message in context.RequestMessages.Where(m => m.Role == Microsoft.Extensions.AI.ChatRole.User
        && m.GetAgentRequestMessageSourceType() == AgentRequestMessageSourceType.External))
    {
        if (!string.IsNullOrWhiteSpace(message.Text))
            report(await extraction.UpdateAsync(message.Text, cancellationToken));

Results and useful failures

AIContextProvider injects before invocation and extracts external User only after success. An assistant answer and the injected block must not enter the writer. forget replaces both business sessions.

These observations are expected from inspecting the linked public code revision. The site lot separately reruns deterministic tests: it does not present an unmeasured generated answer or provider score as observed output.

Persistence and limits

Facts in Demo150/160 and the Demo170 comparison stay in-process. Demo130 retains SQLite context only; Demo140 retains its JSON snapshot. Forgetting one session does not purge other stores or backups. Admission errors remain visible without fallback. Scripted tests alone qualify no model.
