docs(workflow-builder): walk Part 15 on Azure; record D-15

7 of 12 pass. The headline is D-15 (fixed in 672868d): the agent chat drawer
was returning 400 on every single message, so the agent was completely unusable
in the browser.

Also corrects my earlier claim that Part 15 was not runnable for want of
credentials — they were configured all along; I had probed my own shell instead
of the backend's environment.

15.12 is recorded as INCONCLUSIVE rather than failed: only 1 of my 2 connect
drags landed an edge, so the chain under test was never built. Consistent with
the rule this walkthrough adopted after four self-caught false positives — a
first-pass failure is unverified until re-probed a second way.

15.9 needs AGENT_MAX_CONVERSATION_TOKENS=1000 plus a backend restart, which is
not something to do to a running stack unasked.

It only asks *you* for a document when the goal is about your specific file. The `source.upload` used for the test-run creates a `Document` (so `documentId` is present at runtime). **Run budget:** repeated re-tests are capped by `AGENT_MAX_RUNS_PER_CONVERSATION` (default 5) — past the cap a run tool returns `run-budget-exceeded` and the agent stops testing.
 - [ ] **15.12 Auto-wire an Artifact-heavy chain.** Build the Azure OCR chain (`submit → poll → extract`) by just connecting the nodes with edges. **Pass:** the `Artifact` identifier ports auto-wire by matching name (`poll.apimRequestId ← submit.apimRequestId`, `extract.ocrResponse ← poll.ocrResponse`) — you should NOT need to hand-bind them; only the `source.upload → file.prepare` hop needs an explicit `documentUrl → blobKey` binding.

+## D-15 — the agent chat was 400ing on every message (fixed, `672868d8`)
+
+The single biggest defect this walkthrough found. The drawer accepted your
+message, showed "Agent", and streamed nothing — forever.
+
+The AI SDK's `DefaultChatTransport` sends `id` and `trigger` alongside our
+payload. `AgentChatRequestDto` never declared them and the global pipe runs with
+`forbidNonWhitelisted: true`, so every request died at the controller boundary:
+
+```
+400 {"message":["property id should not exist","property trigger should not exist"]}
+```
+
+Both are now declared optional and documented as accepted-and-ignored.
+
+**Why nothing caught it.** The backend and Azure are healthy — a hand-built
+request streams GPT-5.4 fine, which is exactly how I first mistook this for an
+environment problem. The agent unit tests pass because class-validator alone
+cannot see whitelisting; that is a `ValidationPipe` concern. And no e2e exercises
+the live chat. The new spec block therefore drives a real `ValidationPipe`, with
+a control asserting a genuinely unknown property is still refused.
+
+This is the same shape as the `/dynamic-nodes` bug that started the whole
+thread: **a contract between two layers, correct on each side in isolation,
+wrong at the join — and only reachable by driving the real UI.**
