       summary: Send a Coach turn (streaming reply)

-        of reply text: `{ type, token }`), `provenance` (the evidence envelope: `{ type, metricSource }`), `suggestion`
-        (a cadence-suggestion card: `{ type, suggestion }`), `reasoning` (v1.18.9, optional reasoning-summary text: `{
-        type, text }` — emitted only by reasoning-capable providers; absent otherwise), `done` (`{ type, conversationId,
-        messageId, usage? }` — v1.18.9 adds the optional `usage` envelope `{ totalTokens, promptTokens?,
-        completionTokens?, model? }`, server-authoritative; clients display it, never recompute), or `error` (`{ type,
-        code, message, reason? }`). The HTTP status is 200 even for a provider/refusal outcome — clients dispatch on the
-        `error` frame, not the status. Clients ignore unknown frame types (additive evolution). Omitting

-        unavailable Coach is refused with the capability envelope before the stream opens, except a missing provider,

+        `text/event-stream`, not JSON: one `data: <json>\n\n` frame per event, each a `CoachStreamEvent` dispatched on
+        `type`. Frames, in the order they arrive: `step` (v1.39.4, live progress while the Coach reads the record: `{
+        type, step }`, upserted by `step.id` from `running` to `done` / `empty` / `failed`; catalog labels, domains,
+        windows and counts only), `token` (a chunk of reply text: `{ type, token }`), `provenance` (the evidence
+        envelope: `{ type, metricSource }`), `result` (v1.39.4, a table of the values the turn read: `{ type, result }`,
+        zero or more, sent only to the account that owns the conversation), `suggestion` (a cadence-suggestion card: `{
+        type, suggestion }`), `suggestedAction` (v1.22, a confirm-to-apply action card: `{ type, suggestedAction }`;
+        nothing is created until the person confirms it through `POST /api/coach/suggested-actions`), `clarification`
+        (v1.39.4, the choices when the reply is a clarifying question: `{ type, clarification }`; answer with
+        `clarification` on the next request), `followUps` (v1.39.4, up to three chips under the reply: `{ type,
+        followUps }`; send one back with `followUp` on the next request), `reasoning` (v1.18.9, optional
+        reasoning-summary text: `{ type, text }` — emitted only by reasoning-capable providers; absent otherwise), and
+        `done` (`{ type, conversationId, messageId, usage? }` — v1.18.9 adds the optional `usage` envelope `{
+        totalTokens, promptTokens?, completionTokens?, model? }`, server-authoritative; clients display it, never
+        recompute), or a single `error` (`{ type, code, message, reason? }`). No frame added after v1.18.9 carries a
+        top-level key an older frame uses, so a client decoding every frame into one flat struct is safe. The HTTP
+        status is 200 even for a provider/refusal outcome — clients dispatch on the `error` frame, not the status.

+ * not know. That makes an unknown frame harmless only while its keys are

+ * shape would make the whole frame fail to decode, and a new frame that
+ * reused one with the same shape would leak a value into whatever the client
+ * does with that key. So a new frame names its payload with a key of its own
+ * (`step`, `result`, `followUps`, `clarification`).
+ *
+ * Reads the frame list from the Zod mirror (`stream-events.ts`), which a
+ * type test holds equal to `CoachStreamEvent`, so a frame added to the
+ * TypeScript union is seen here too.
+ *
+ * Checked by breaking it: adding `message: z.string()` to the `step` frame in
+ * `stream-events.ts` turns the second test red and names the frame and key.
