Invariant 01

Nothing is acknowledged until it is durable - a client is told "synced" only when Plaud really has the file.

Invariant 02

Processing is a queue, not a request - workers scale out, and every failure has a defined path back.

Invariant 03

Retrieval is a contract, not a top-k call - a weak question returns nothing instead of noise.
