Demo440 — Context Budget

Prepare the live experiment

Demo440.App references Maf.Memory, Maf.Observability and the common connection. An available chat provider is required, Ollama granite4:3b by default or an explicitly configured API. This scenario uses neither embeddings nor RAG. Donnees/dossier_support_volumineux.txt is copied to output; its content remains unchanged, including French labels used by the filter.

dotnet build BaseTechnique.slnx -m:1 -c Release

• Demo150 — Shared Facts

• Demo420 — Safe Telemetry

Run through the final ledger

dotnet run --project demos/Demo440_ContextBudget/Demo440.App.csproj -c Release --no-build

The program runs then exits without a menu. Read raw-corpus and scenario-specific-line-filter, memory updates, context policies, then NativeWindow and Experiment coverage including auxiliary calls. For each stage retain size, available provider usage and answer. Failure exits 1 with Context experiment failed; no savings are inferred.

string selected = string.Join('\n', corpus.Split('\n').Where(line =>
    line.StartsWith("Client :", StringComparison.OrdinalIgnoreCase)
    || line.StartsWith("Situation :", StringComparison.OrdinalIgnoreCase)
    || line.StartsWith("Impact :", StringComparison.OrdinalIgnoreCase)
    || line.StartsWith("Contrainte", StringComparison.OrdinalIgnoreCase)
    || line.StartsWith("Point métier", StringComparison.OrdinalIgnoreCase)
    || line.Contains("billing.outbound", StringComparison.OrdinalIgnoreCase)));
if (string.IsNullOrWhiteSpace(selected))
    throw new InvalidDataException("The explicit scenario filter selected no lines. No fallback.");

Compare retained facts

In a corpus copy, move a prohibition outside selected prefixes; observe whether it disappears from transmitted context. In ContextExperiment, compare full, window-last-3, generated-summary-unverified and bounded-user-facts with the same question. Check Billing, SQL Server 2022 and the nightly-restart prohibition. Do not treat a plausible answer as fidelity evidence.

Keep an attributable table

Console.WriteLine("This line filter is deterministic selection for this fixture. Native MAF compaction and history policies follow.");
await ContextExperiment.RunAsync(chat, stop.Token);
Console.WriteLine("Experiment coverage including auxiliary calls: " + JsonSerializer.Serialize(ledger.Summarize()));
Console.WriteLine("All extraction, summary and compaction calls are reported separately. No cost or savings claim; answer quality must be evaluated separately.");

Interpret without claiming savings

The estimate need not cover the whole request. A summary can lose or invent a fact; window compaction removes turns without summarizing. Extraction and summary add requests. Null values remain unknown. This page publishes no new live campaign or price comparison; the default profile remains unqualified.
