"""Shared async Redis client.
|
||
|
|
|
||
|
|
Redis is used as scratch / cache only — never as a system of record. We
|
||
|
|
disable RDB/AOF in compose so a restart wipes state, which matches the
|
||
|
|
"ephemeral pie" property: anything the server temporarily holds during
|
||
|
|
/api/analyze or /api/portfolio/parse must not survive a restart.
|
||
|
|
|
||
|
|
The client is module-singleton; FastAPI handlers get it via get_redis()."""
