Drops porting-history narratives (dodrenett), superseded-behavior
explanations, and restatements of what the next line does. Constraint
notes (fail-closed policies, CAS semantics, cascade behavior, id
uniqueness) stay, just shorter. No code changes.

-//! Plain NATS event publishing - ported from dodrenett's lib/nats.ts
-//! (AnswerSubmitted). Deliberately just a publish, no stream/consumer
-//! bookkeeping here: whoever reads `portal.answers.submitted` today is a
-//! person watching the subject; a future LLM-driven follow-up poster
-//! reads the exact same subject and shape, so this doesn't need to
-//! change shape when that shows up, only gain a second subscriber.
+//! Plain NATS publish of every submission/decision - fire and forget,
+//! no stream bookkeeping. The n8n automations subscribe to
+//! `portal.answers.submitted` and gate on `question_id`/`alternative`.
