From a6f88cf310557d9609688cb12eff6c2b702dd711 Mon Sep 17 00:00:00 2001 From: Krishnadheeraj <12496535+DheerajPannala@users.noreply.github.com> Date: Wed, 9 Sep 2026 20:55:34 +0000 Subject: [PATCH 1/8] fix(samples): isolate app-only OBS auth and use S2S endpoints Configure S2S OBS across sample languages, add isolated blueprint-to-agent application-token providers, preserve workload OBO, and cover routing and authentication failure paths.

Legacy Node.js SDKs use +`/observabilityService/tenants/{tenant}/agents/{agent}/traces`; the distro, Python, +.NET and Apex exporters use `/observabilityService/tenants/{tenant}/otlp/agents/{agent}/traces`. +The inspected service implements both route shapes with the same +`ExportTraceServiceRequest` body type. The legacy service route has distinct +tenant-eligibility/service-principal authorization policies: do not infer general +acceptance or caller-allowlist enforcement from the public OTLP role check. +Live authorization remains unverified for the available incomplete configuration. + +Devin, Copilot Studio and Perplexity pin the coherent preview.115 SDK family to +retain their verified scope APIs. OpenAI and Vercel retain their existing +preview.125 dependency family. All five configure their legacy exporter once in +`src/otel.ts` and reject `ENABLE_A365_OBSERVABILITY_PER_REQUEST_EXPORT`: that mode +would bypass the OBS-only resolver and read a context token. There is no need for +an unpublished SDK or a suffix-only payload migration. + +LangChain's published distro 1.4.0 configuration disables `a365.durableDelivery` +because that release can otherwise replay historical route choices. Existing +spool data is not deleted. Do not re-enable replay until the installed release +enforces S2S for both live and replayed exports. No sample falls back to `/observability`. + +**Authentication prerequisite (source-verified, not live-verified):** The inspected +S2S service contract accepts only service-principal/application tokens. +The public `/otlp/agents/` route requires `Agent365.Observability.OtelWrite` in +`roles`, not `scp`. Configure application-role consent rather than assuming a +tenant-specific permission exemption. Delegated AI Teammate/OBO tokens carrying +`scp` are rejected. +Selecting S2S does not convert a delegated token into an application token. +The presence of `scp` makes a token a user principal even if it also has `roles` +or an application-looking `idtyp`; additional permissions do not bypass this gate. + +The autonomous/Salesforce examples acquire application tokens with `roles`. +Interactive samples now use a **separate OBS-only application-token provider**; +they do not obtain exporter tokens from business MCP/Graph/OBO caches. The provider +uses blueprint credentials plus `fmi_path` for the actual agent instance, then +exchanges that parent assertion through a second `client_credentials` grant for +the OBS audience. There is no `user_fic`, OBO assertion, or delegated-token fallback +in this flow. Business authentication and user context remain independent. + +Node.js and Python interactive samples require `AGENT365_OBS_TENANT_ID`, +`AGENT365_OBS_AGENT_ID`, `AGENT365_OBS_BLUEPRINT_CLIENT_ID`, and +`AGENT365_OBS_BLUEPRINT_CLIENT_SECRET` when OBS export is enabled. Their supplied +credential flow is a development example; store secrets securely. .NET uses the +equivalent dedicated `Agent365Observability` configuration and additionally +supports managed-identity assertions. See each sample's template and README. +Providers reject missing/placeholder configuration, blueprint-as-agent IDs, +export identity mismatches, delegated tokens, wrong audiences and expired tokens. +They cache only valid app tokens until their actual expiry and fail explicitly +instead of returning empty or stale tokens. No provisioning or permissions are +changed by the samples. + +Use the provisioned runtime Agent Identity, not the Agent Blueprint ID, for agent +attribution and the agent-bound OBS token flow. Incomplete provisioning is not a +valid AI Teammate test setup. A token-acquisition failure such as `AADSTS82001` +must be resolved before ingestion can be tested; changing the exporter URL cannot +repair a rejected token grant. +Do not fix a 401/403 by switching routes. Console/OTLP-only examples do not become +authenticated OBS examples merely by enabling the exporter; they also require +the dedicated application credentials and permissions. + +**Validation:** Run the offline route/configuration regressions with +`python -m pytest tests/observability` from an environment with pytest and +`microsoft-agents-a365-observability-core>=1.0.0` installed (both are existing +Python sample dependencies). These inspect configuration, mock both token-exchange +requests, and mock HTTP exports for AI Teammate/OBO contexts, including failures, +cache expiry and identity mismatches, without starting agents or contacting services. +Node.js token-flow/route tests run with +`node --test tests/observability/node-app-token.test.cjs` after installing the +Node.js sample dependencies. .NET tests run with +`dotnet test tests/e2e/Agent365.E2E.Tests.csproj --filter FullyQualifiedName~ObservabilityAppTokenTests`. +Salesforce route/401 regressions extend `A365TelemetryTest` and require an +authorized test org. Live AI Teammate and OBO validation must independently check +the exported request's S2S path, audience, agent/tenant attribution, response, +and unchanged tool authentication; offline checks alone do not establish live +authorization success. +The S2S service also sanitizes `user.id` and its aliases unless the host/agent has +an authorized trusted-host or service exemption. Preserving user baggage in the +client's exported payload therefore does **not** prove that downstream OBO caller +attribution is retained. Validate attribution after ingestion using the approved +service configuration; do not alter identities to bypass this restriction. + The SDK versions used by each sample are displayed in the **E2E test workflow summaries**.

No observability code needed (the instrumentor handles it). 5. **Step 4 — Run + flush.** `InvokeAgentScope` wraps `agent.invoke(...)` so the run gets a top-level `invoke_agent ` span; `force_flush()` is critical — without it, batched spans may not export before the process exits. @@ -90,6 +90,37 @@ To diff against your own app: copy Steps 1, 2, and 2b into the file where your a - **No spans printed to stdout** — `BatchSpanProcessor` may not have flushed; the sample calls `force_flush()` on exit, so make sure the script ran to completion. - **`KeyError` or auth error from OpenAI** — verify `OPENAI_API_KEY` (or `AZURE_OPENAI_*` variables) in `.env`. `langchain-openai` reads these directly. - **Spans missing from your OTLP backend (after swap)** — temporarily fall back to `ConsoleSpanExporter` to confirm the SDK is producing spans.

Krishnadheeraj <12496535+DheerajPannala@users.noreply.github.com> Date: Wed, 23 Sep 2026 10:53:33 +0100 Subject: [PATCH 2/8] fix(samples): support roleless OBS and address auth reviews Preserve workload OBO while accepting explicitly app-only roleless OBS tokens. Add independent business-auth contract guards, narrow .NET acquisition failures, harden fixture paths, and reuse the managed-identity exchange scope. Align OpenAI dependencies and update registration and authentication guidance. Review response amendments: - Roleless tokens now also accepted when oid==sub (with no scp), because Entra may not emit idtyp=app for the OBS resource in every tenant. Delegated tokens have oid != sub, so this stays app-only. - Restore the .NET "never leak secrets" guarantee: sanitize CryptographicException, IOException, and any unexpected non-programming exception; still propagate InvalidOperation/NullReference/Argument/KeyNotFound/Overflow as programming failures. - Widen the OpenAI tracing smoke fixture timeout to tolerate cold-cache require() resolution. Follow-ups (session files/pr-followups.md): - Bump sample SDK once #290 publishes and remove the per-request-export startup rejection. - Live-verify roleless acceptance against a second tenant and an OBO-authorized agent.

Tokens without idtyp still work with valid nonempty roles. The .NET autonomous README no longer implies that the service requires idtyp=app. Also use Select projections for the five claim loops and Path.Join for the validated fixture filename in ObservabilityAppTokenTests.
