"""Guard against the Python and Go protocol constants drifting apart.
|
|
|
|
The wire protocol is declared twice — ``strix/interface/tui/backend/protocol.py``
|
|
for the backend and ``strix/interface/tui/internal/protocol/protocol.go`` for the
|
|
sidecar. This test parses the Go source shipped in the tree and checks the two
|
|
declarations agree, so a version or capability change in one language cannot
|
|
land silently without the other.
