/**
|
||||
* 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.
