test(coach): pin the chat turn as golden SSE transcripts
Drive POST /api/insights/chat through the real SSE stream and the real reply guards for every branch a turn can take: tool mode with present, drifted and missing figures, the no-tools path, inbound and replayed refusals, the budget refusal, each provider failure class, a cancelled turn, the outbound block, every sentinel in its valid and malformed forms, learn-link scrubbing, the three no-provider paths, a workout scope, the post-call defect path, and the refusals that answer before the stream opens. Each transcript records the frames the client receives (heartbeat comments dropped) and the ordered side effects: persisted messages, budget reserve and reconcile, audit rows, annotate names with their meta keys, and the provider inputs as prompt fingerprints.

/**
|
||||
* Shared fixtures for the Coach chat golden transcripts.
|
||||
*
|
||||
* The golden suite drives `POST /api/insights/chat` end to end through the
|
||||
* real SSE stream (`createSseStream` is NOT mocked) and the real reply guards
|
||||
* (sentinel parsers, outbound screen, grounding ledger, learn-link scrub,
|
||||
* refusal detector, request builder). Only the boundaries are replaced: auth,
|
||||
* the database, providers, budget, snapshot, tools, persistence and the
|
||||
* observability sinks.
|
||||
*
|
||||
* Every replaced boundary writes to one ordered call log, so a transcript
|
||||
* pins both halves of a turn: the frames the client sees (heartbeat comments
|
||||
* dropped) and the side effects in the order they happened.
|
||||
*
|
||||
* The test file registers the module mocks itself (vi.mock is hoisted per
|
||||
* file) and points each factory at the objects exported here.
